By the time he tested positive for COVID-19 on Jan. 12, Gary Herritz was feeling pretty sick. He suspects he was infected a week earlier, during a medical appointment in which he saw health workers who were wearing masks beneath their noses or who had removed them entirely.

His scratchy throat had turned to a dry cough, headache, joint pain, and fever – all warning signs to Mr. Herritz, who underwent liver transplant surgery in 2012, followed by a rejection scare in 2018. He knew his compromised immune system left him especially vulnerable to a potentially deadly case of COVID.

“The thing with transplant patients is we can crash in a heartbeat,” said Mr. Herritz, 39. “The outcome for transplant patients [with COVID] is not good.”

On Twitter, Mr. Herritz had read about monoclonal antibody therapy, the treatment famously given to President Donald Trump and other high-profile politicians and authorized by the Food and Drug Administration for emergency use in high-risk COVID patients. But as his symptoms worsened, Mr. Herritz found himself very much on his own as he scrambled for access.

His primary care doctor wasn’t sure he qualified for treatment. His transplant team in Wisconsin, where he’d had the liver surgery, wasn’t calling back. No one was sure exactly where he should go to get it. From bed in Pascagoula, Miss., he spent 2 days punching in phone numbers, reaching out to health officials in four states, before he finally landed an appointment to receive a treatment aimed at keeping patients like him out of the hospital – and, perhaps, the morgue.

“I am not rich, I am not special, I am not a political figure,” Mr. Herritz, a former community service officer, wrote on Twitter. “I just called until someone would listen.”

Months after Mr. Trump emphatically credited an experimental antibody therapy for his quick recovery from covid and even as drugmakers ramp up supplies, only a trickle of the product has found its way into regular people. While hundreds of thousands of vials sit unused, sick patients who, research indicates, could benefit from early treatment – available for free – have largely been fending for themselves.

Federal officials have allocated more than 785,000 doses of two antibody treatments authorized for emergency use during the pandemic, and more than 550,000 doses have been delivered to sites across the nation. The federal government has contracted for nearly 2.5 million doses of the products from drugmakers Eli Lilly and Regeneron Pharmaceuticals at a cost of more than $4.4 billion.

So far, however, only about 30% of the available doses have been administered to patients, U.S. Department of Health & Human Services officials said.

Scores of high-risk COVID patients who are eligible remain unaware or have not been offered the option. Research has shown the therapy is most effective if given early in the illness, within 10 days of a positive COVID test. But many would-be recipients have missed this crucial window because of a patchwork system in the United States that can delay testing and diagnosis.

“The bottleneck here in the funnel is administration, not availability of the product,” said Dr. Janet Woodcock, a veteran FDA official in charge of therapeutics for the federal Operation Warp Speed effort.

Among the daunting hurdles: Until this week, there has been no nationwide system to tell people where they could obtain the drugs, which are delivered through IV infusions that require hours to administer and monitor. Finding space to keep COVID-infected patients separate from others has been difficult in some health centers slammed by the pandemic.

“The health care system is crashing,” Dr. Woodcock told reporters. “What we’ve heard around the country is the No. 1 barrier is staffing.”

At the same time, many hospitals have refused to offer the therapy because doctors were unimpressed with the research federal officials used to justify its use.

Monoclonal antibodies are lab-produced molecules that act as substitutes for the body’s own antibodies that fight infection. The COVID treatments are designed to block the SARS-CoV-2 virus that causes infection from attaching to and entering human cells. Such treatments are usually prohibitively expensive, but for the time being the federal government is footing the bulk of the bill, though patients likely will be charged administrative fees.

Nationwide, nearly 4,000 sites offer the infusion therapies. But for patients and families of people most at risk – those 65 and older or with underlying health conditions – finding the sites and gaining access has been almost impossible, said Brian Nyquist, chief executive officer of the National Infusion Center Association, which is tracking supplies of the antibody products. Like Mr. Herritz, many seeking information about monoclonals find themselves on a lone crusade.

“If they’re not hammering the phones and advocating for access for their loved ones, others often won’t,” he said. “Tenacity is critical.”

Regeneron officials said they’re fielding calls about COVID treatments daily to the company’s medical information line. More than 3,500 people have flooded Eli Lilly’s COVID hotline with questions about access.

As of this week, all states are required to list on a federal locator map sites that have received the monoclonal antibody products, HHS officials said. The updated map shows wide distribution, but a listing doesn’t guarantee availability or access; patients still need to check. It’s best to confer with a primary care provider before reaching out to the centers. For best results, treatment should occur as soon as possible after a positive COVID test.

Some health systems have refused to offer the monoclonal antibody therapies because of doubts about the data used to authorize them. Early studies suggested that Lilly’s therapy, bamlanivimab, reduced the need for hospitalization or emergency treatment in outpatient COVID cases by about 70%, while Regeneron’s antibody cocktail of casirivimab plus imdevimab reduced the need by about 50%.

But those studies were small, just a few hundred subjects, and the results were limited. “A lot of doctors, actually, they’re not impressed with the data,” said Dr. Daniel Griffin, an infectious disease expert at Columbia University who cohosts the podcast “This Week in Virology.” “There really is still that question of, ‘Does this stuff really work?’ ”

As more patients are treated, however, there’s growing evidence that the therapies can keep high-risk patients out of the hospital, not only easing their recovery but also decreasing the burden on health systems struggling with record numbers of patients.

Dr. Raymund Razonable, an infectious disease expert at the Mayo Clinic in Minnesota, said he has treated more than 2,500 COVID patients with monoclonal antibody therapy with promising results. “It’s looking good,” he said, declining to provide details because they’re embargoed for publication. “We are seeing reductions in hospitalizations; we’re seeing reductions in ICU care; we’re also seeing reductions in mortality.”

Banking on observations from Mayo experts and others, federal officials have been pushing for wider use of antibody therapies. HHS officials have partnered with hospitals in three hard-hit states – California, Arizona, and Nevada – to set up infusion centers that are treating dozens of COVID patients each day.

One of those sites went up in late December at El Centro Regional Medical Center in California’s Imperial County, an impoverished farming region on the state’s southern border that has recorded among the highest COVID infection rates in the state. For months, the medical center strained to absorb the overwhelming influx of patients, but chief executive Dr. Adolphe Edward said a new walk-up infusion site has already put a dent in the COVID load.

More than 130 people have been treated, all patients who were able to get the 2-hour infusions and then recuperate at home. “If those folks would not have had the treatment, they would have come through the emergency department and we would have had to admit the lion’s share of them,” he said.

It’s important to make sure people in high-risk groups know to seek out the therapy and to get it early, Dr. Edward said. He and his staff have been working with area doctors’ offices and nonprofit groups and relying on word of mouth.

“On multiple levels, we’re saying, ‘If you’ve tested positive for the virus, come and let us see if you are eligible,’ ” Dr. Edward said.

Greater awareness is a goal of the HHS effort, said Dr. John Redd, chief medical officer for the assistant secretary for preparedness and response. “These antibodies are meant for everyone,” he said. “Everyone across the country should have equal access to these products.”

For now, patients like Mr. Herritz, the Mississippi liver transplant recipient, say reality is falling well short of that goal. If he hadn’t continued to call in search of a referral, he wouldn’t have been treated. And without the therapy, Mr. Herritz believes, he was just days away from hospitalization.

“I think it’s horrible that if I didn’t have Twitter, I wouldn’t know anything about this,” he said. “I think about all the people who have died not knowing this was an option for high-risk individuals.”

It’s in the nature of presidential candidates and new presidents to promise big things. Just months after his 1961 inauguration, President John F. Kennedy vowed to send a man to the moon by the end of the decade. That pledge was kept, but many others haven’t been, such as candidate Bill Clinton’s promise to provide universal health care and presidential hopeful George H.W. Bush’s guarantee of no new taxes.

Now, during a once-in-a-century pandemic, incoming President Joe Biden has promised to provide 100 million COVID-19 vaccinations in his first 100 days in office.

“This team will help get … at least 100 million covid vaccine shots into the arms of the American people in the first 100 days,” Biden said during a Dec. 8 news conference introducing key members of his health team.

When first asked about his pledge, the Biden team said the president-elect meant 50 million people would get their two-dose regimen. The incoming administration has since updated this plan, saying it will release vaccine doses as soon as they’re available instead of holding back some of that supply for second doses.

Either way, Biden may run into difficulty meeting that 100 million mark.

“I think it’s an attainable goal. I think it’s going to be extremely challenging,” said Claire Hannan, executive director of the Association of Immunization Managers.

While a pace of 1 million doses a day is “somewhat of an increase over what we’re already doing,” a much higher rate of vaccinations will be necessary to stem the pandemic, said Larry Levitt, executive vice president for health policy at Kaiser Family Foundation. (KHN is an editorially independent program of KFF.) “The Biden administration has plans to rationalize vaccine distribution, but increasing the supply quickly” could be a difficult task.

Under the Trump administration, vaccine deployment has been much slower than Biden’s plan. The rollout began on Dec. 14. Since then, 12 million shots have been given and 31 million doses have been shipped out, according to the Centers for Disease Control and Prevention’s vaccine tracker.

This sluggishness has been attributed to a lack of communication between the federal government and state and local health departments, not enough funding for large-scale vaccination efforts, and confusing federal guidance on distribution of the vaccines.

The same problems could plague the Biden administration, said experts.

States still aren’t sure how much vaccine they’ll get and whether there will be a sufficient supply, said Dr. Marcus Plescia, chief medical officer for the Association of State and Territorial Health Officials, which represents state public health agencies.

“We have been given little information about the amount of vaccine the states will receive in the near future and are of the impression that there may not be 1 million doses available per day in the first 100 days of the Biden administration,” said Dr. Plescia. “Or at least not in the early stages of the 100 days.”

Another challenge has been a lack of funding. Public health departments have had to start vaccination campaigns while also operating testing centers and conducting contact tracing efforts with budgets that have been critically underfunded for years.

“States have to pay for creating the systems, identifying the personnel, training, staffing, tracking people, information campaigns – all the things that go into getting a shot in someone’s arm,” said Jennifer Kates, director of global health & HIV policy at KFF. “They’re having to create an unprecedented mass vaccination program on a shaky foundation.”

The latest covid stimulus bill, signed into law in December, allocates almost $9 billion in funding to the CDC for vaccination efforts. About $4.5 billion is supposed to go to states, territories and tribal organizations, and $3 billion of that is slated to arrive soon.

But it’s not clear that level of funding can sustain mass vaccination campaigns as more groups become eligible for the vaccine.

Biden released a $1.9 trillion plan last week to address covid and the struggling economy. It includes $160 billion to create national vaccination and testing programs, but also earmarks funds for $1,400 stimulus payments to individuals, state and local government aid, extension of unemployment insurance, and financial assistance for schools to reopen safely.

Though it took Congress almost eight months to pass the last covid relief bill after Republican objections to the cost, Biden seems optimistic he’ll get some Republicans on board for his plan. But it’s not yet clear that will work.

There’s also the question of whether outgoing President Donald Trump’s impeachment trial will get in the way of Biden’s legislative priorities.

In addition, states have complained about a lack of guidance and confusing instructions on which groups should be given priority status for vaccination, an issue the Biden administration will need to address.

On Dec. 3, the CDC recommended health care personnel, residents of long-term care facilities, those 75 and older, and front-line essential workers should be immunized first. But on Jan. 12, the CDC shifted course and recommended that everyone over age 65 should be immunized. In a speech Biden gave on Jan. 15 detailing his vaccination plan, he said he would stick to the CDC’s recommendation to prioritize those over 65.

Outgoing Health and Human Services Secretary Alex Azar also said on Jan. 12 that states that moved their vaccine supply fastest would be prioritized in getting more shipments. It’s not known yet whether the Biden administration’s CDC will stick to this guidance. Critics have said it could make vaccine distribution less equitable.

In general, taking over with a strong vision and clear communication will be key to ramping up vaccine distribution, said Ms. Hannan.

“Everyone needs to understand what the goal is and how it’s going to work,” she said.

A challenge for Biden will be tamping expectations that the vaccine is all that is needed to end the pandemic. Across the country, covid cases are higher than ever, and in many locations officials cannot control the spread.

Public health experts said Biden must amp up efforts to increase testing across the country, as he has suggested he will do by promising to establish a national pandemic testing board.

With so much focus on vaccine distribution, it’s important that this part of the equation not be lost. Right now, “it’s completely all over the map,” said KFF’s Ms. Kates, adding that the federal government will need a “good sense” of who is and is not being tested in different areas in order to “fix” public health capacity.

Jan. 20, 2021, marks the launch of The Biden Promise Tracker, which monitors the 100 most important campaign promises of President Joseph R. Biden. Biden listed the coronavirus and a variety of other health-related issues among his top priorities. You can see the entire list – including improving the economy, responding to calls for racial justice and combating climate change – here. As part of KHN’s partnership with PolitiFact, we will follow the health-related issues and then rate them on whether the promise was achieved: Promise Kept, Promise Broken, Compromise, Stalled, In the Works or Not Yet Rated. We rate the promise not on the president’s intentions or effort, but on verifiable outcomes. PolitiFact previously tracked the promises of President Donald Trump and President Barack Obama.

Either way, Biden may run into difficulty meeting that 100 million mark.

“I think it’s an attainable goal. I think it’s going to be extremely challenging,” said Claire Hannan, executive director of the Association of Immunization Managers.

While a pace of 1 million doses a day is “somewhat of an increase over what we’re already doing,” a much higher rate of vaccinations will be necessary to stem the pandemic, said Larry Levitt, executive vice president for health policy at Kaiser Family Foundation. (KHN is an editorially independent program of KFF.) “The Biden administration has plans to rationalize vaccine distribution, but increasing the supply quickly” could be a difficult task.

Under the Trump administration, vaccine deployment has been much slower than Biden’s plan. The rollout began on Dec. 14. Since then, 12 million shots have been given and 31 million doses have been shipped out, according to the Centers for Disease Control and Prevention’s vaccine tracker.

This sluggishness has been attributed to a lack of communication between the federal government and state and local health departments, not enough funding for large-scale vaccination efforts, and confusing federal guidance on distribution of the vaccines.

The same problems could plague the Biden administration, said experts.

States still aren’t sure how much vaccine they’ll get and whether there will be a sufficient supply, said Dr. Marcus Plescia, chief medical officer for the Association of State and Territorial Health Officials, which represents state public health agencies.

“We have been given little information about the amount of vaccine the states will receive in the near future and are of the impression that there may not be 1 million doses available per day in the first 100 days of the Biden administration,” said Dr. Plescia. “Or at least not in the early stages of the 100 days.”

Another challenge has been a lack of funding. Public health departments have had to start vaccination campaigns while also operating testing centers and conducting contact tracing efforts with budgets that have been critically underfunded for years.

“States have to pay for creating the systems, identifying the personnel, training, staffing, tracking people, information campaigns – all the things that go into getting a shot in someone’s arm,” said Jennifer Kates, director of global health & HIV policy at KFF. “They’re having to create an unprecedented mass vaccination program on a shaky foundation.”

The latest covid stimulus bill, signed into law in December, allocates almost $9 billion in funding to the CDC for vaccination efforts. About $4.5 billion is supposed to go to states, territories and tribal organizations, and $3 billion of that is slated to arrive soon.

But it’s not clear that level of funding can sustain mass vaccination campaigns as more groups become eligible for the vaccine.

Biden released a $1.9 trillion plan last week to address covid and the struggling economy. It includes $160 billion to create national vaccination and testing programs, but also earmarks funds for $1,400 stimulus payments to individuals, state and local government aid, extension of unemployment insurance, and financial assistance for schools to reopen safely.

Though it took Congress almost eight months to pass the last covid relief bill after Republican objections to the cost, Biden seems optimistic he’ll get some Republicans on board for his plan. But it’s not yet clear that will work.

There’s also the question of whether outgoing President Donald Trump’s impeachment trial will get in the way of Biden’s legislative priorities.

In addition, states have complained about a lack of guidance and confusing instructions on which groups should be given priority status for vaccination, an issue the Biden administration will need to address.

On Dec. 3, the CDC recommended health care personnel, residents of long-term care facilities, those 75 and older, and front-line essential workers should be immunized first. But on Jan. 12, the CDC shifted course and recommended that everyone over age 65 should be immunized. In a speech Biden gave on Jan. 15 detailing his vaccination plan, he said he would stick to the CDC’s recommendation to prioritize those over 65.

Outgoing Health and Human Services Secretary Alex Azar also said on Jan. 12 that states that moved their vaccine supply fastest would be prioritized in getting more shipments. It’s not known yet whether the Biden administration’s CDC will stick to this guidance. Critics have said it could make vaccine distribution less equitable.

In general, taking over with a strong vision and clear communication will be key to ramping up vaccine distribution, said Ms. Hannan.

“Everyone needs to understand what the goal is and how it’s going to work,” she said.

A challenge for Biden will be tamping expectations that the vaccine is all that is needed to end the pandemic. Across the country, covid cases are higher than ever, and in many locations officials cannot control the spread.

Public health experts said Biden must amp up efforts to increase testing across the country, as he has suggested he will do by promising to establish a national pandemic testing board.

With so much focus on vaccine distribution, it’s important that this part of the equation not be lost. Right now, “it’s completely all over the map,” said KFF’s Ms. Kates, adding that the federal government will need a “good sense” of who is and is not being tested in different areas in order to “fix” public health capacity.

Jan. 20, 2021, marks the launch of The Biden Promise Tracker, which monitors the 100 most important campaign promises of President Joseph R. Biden. Biden listed the coronavirus and a variety of other health-related issues among his top priorities. You can see the entire list – including improving the economy, responding to calls for racial justice and combating climate change – here. As part of KHN’s partnership with PolitiFact, we will follow the health-related issues and then rate them on whether the promise was achieved: Promise Kept, Promise Broken, Compromise, Stalled, In the Works or Not Yet Rated. We rate the promise not on the president’s intentions or effort, but on verifiable outcomes. PolitiFact previously tracked the promises of President Donald Trump and President Barack Obama.

It’s in the nature of presidential candidates and new presidents to promise big things. Just months after his 1961 inauguration, President John F. Kennedy vowed to send a man to the moon by the end of the decade. That pledge was kept, but many others haven’t been, such as candidate Bill Clinton’s promise to provide universal health care and presidential hopeful George H.W. Bush’s guarantee of no new taxes.

Now, during a once-in-a-century pandemic, incoming President Joe Biden has promised to provide 100 million COVID-19 vaccinations in his first 100 days in office.

“This team will help get … at least 100 million covid vaccine shots into the arms of the American people in the first 100 days,” Biden said during a Dec. 8 news conference introducing key members of his health team.

When first asked about his pledge, the Biden team said the president-elect meant 50 million people would get their two-dose regimen.

A one-stop shop approach to managing the spectrum of complications in patients with type 2 diabetes with a coordinated, multidisciplinary team of clinicians has taken root in at least two U.S. medical centers, and their efforts have now joined to take this concept national through the Cardiometabolic Center Alliance, which hopes to have at least 20 such centers running by the end of 2022.

Doug Brunk/MDedge News

In patients with type 2 diabetes (T2D), “multiple organs are affected by the same disease process,” notably the heart, kidneys, vasculature, and liver, but the care these patients often receive today is “fragmented, and typically without good coordination,” explained Mikhail N. Kosiborod, MD, a cardiologist and codirector of the Saint Luke’s Michael & Marlys Haverty Cardiometabolic Center of Excellence in Kansas City, Mo.

“We need to depart from the outdated idea that each medical specialty focuses on an organ system. It’s one patient with one disease that affects multiple organs and needs comprehensive, multidisciplinary care,” he said.

Historically, “we’ve looked to primary care physicians to ‘conduct the orchestra’ for complex, multispecialty care” for patients with T2D, but a recent “avalanche” of new treatments with new data and recommendations has made coordination by a single, generalist physician essentially impossible. “It isn’t realistic” to expect a single primary care physician to coordinate all the care a patient with T2D now needs to receive, said Dr. Kosiborod, who is also a professor of medicine at the University of Missouri–Kansas City. Plus, “patients can get lost” when they try to navigate on their own among several physicians, possibly in disparate locations, and without fully understanding what each physician is responsible for managing.
 

Application of recommended treatments ‘lagging’

“The data are there, and the recommendations are there for T2D and cardiovascular disease, heart failure, and diabetic kidney disease, but the problem has been implementation,” said Dr. Kosiborod. “Application in practice is lagging way behind the recommendations.” That led him and his associates to devise a “new model of care for patients with T2D,” the cardiometabolic center (CMC), as a status quo alternative.

The CMC paradigm is that patients with T2D, especially those with existing cardiovascular or chronic kidney disease or at high risk for these complications, undergo assessment and treatment at one site from a multidisciplinary staff of physicians and allied caregivers including nurse practitioners, nurse coordinators, pharmacists, dieticians, and diabetes educators who are cross-trained for managing both T2D and cardiovascular diseases.

The Cardiometabolic Center Alliance builds on the idea that this care model is defined by a set of detailed treatment protocols and processes of care that other sites can adopt to boost the number of patients aided by this approach, to gather data from a larger patient pool in a dedicated registry to better document the program’s impact, and to form a quality-improvement network that can collectively improve performance.

“It’s absolutely replicable,” maintained Dr. Kosiborod, who is also executive director of the Cardiometabolic Center Alliance. “We’ve codified all of the care and medications into an impressive package. We now have something that works, and many other centers are interested in building programs like this. By establishing a base of well-defined protocols and operating procedures we can train a cadre of allied professionals who can effectively implement the program across wider populations of patients, while using the brick and mortar center to manage more complex patients,” he added.

“We’re not taking patients” from primary care physicians, Dr. Kosiborod stressed. “We’re helping generalists give better care. They already have their hands full. We’re here to help physicians do better.”

He cited a recent study of 1,735 patients with atherosclerotic cardiovascular disease and diabetes (96% with T2D) enrolled in a registry at 119 U.S. sites during 2016-2018 that found less than 7% were on the full range of guideline-directed medical therapy that they qualified for based on existing treatment guidelines. “This is not acceptable,” Dr. Kosiborod declared.

“It’s so obvious that this needs to be a combined approach. It’s very difficult to have one provider take care of all of the T2D complications. There needs to be a new approach, and [the Cardiometabolic Center program at Saint Luke’s] has done a great job getting their initiative underway to take a more global approach,” commented Ralph A. DeFronzo, MD, chief of the diabetes division and professor of medicine at the University of Texas Health Science Center, San Antonio.
 

Early results show improved metrics

The Saint Luke’s Haverty CMC launched in 2019, and data from its first 129 patients with at least one follow-up visit documented early efficacy for the program, as reported at the American Heart Association’s Quality of Care and Outcome’s Research meeting, held virtually on May 15 and 16, 2020.

That analysis from Dr. Kosiborod and associates compared various short-term metrics among their CMC patients against a control cohort of 387 similar patients with T2D who also received care in the Saint Luke’s Health System during 2019 but outside of the CMC. This observational study involved no patient randomization, but the researchers used propensity scoring to match the control patients with those managed in the CMC by several demographic and clinical parameters.

During follow-up that was generally less than 6 months, patients managed in the CMC averaged 12 pounds of weight loss, a 0.5% reduction in their average hemoglobin A1c, a mean 4.6–mm Hg cut in their systolic blood pressure, an average drop in their LDL cholesterol of 11.4 mg/dL, and among those receiving insulin the daily, average insulin dose fell by a relative 43%, compared with baseline. Among the controls, averages for these five parameters were weight loss of 2 pounds, a cut in A1c of 0.2%, a systolic blood pressure reduction of 0.6 mm Hg, a drop in LDL cholesterol of 4.9 mg/dL, and a relative rise in insulin dose of 6%. All of these between group differences were statistically significant except for LDL cholesterol.

Additional analysis of the medications that patients in the CMC and control group received also showed striking differences. Combined prescriptions for all components of guideline-directed medical therapy went to 41% of the CMC patients, compared with 2% of the controls, a statistically significant difference. Contributing to this difference were significantly increased rates of prescriptions for ACE inhibitors and statins.

The CMC staff also started 57% of their patients on a SGLT2 inhibitor and 90% on a GLP-1 receptor agonist (GLP-1 RA), compared with rates of 18% and 13%, respectively, among controls. Both of these between-group differences were also significant, and they highlighted the willingness and success of the CMC clinicians to put a large number of their patients on agents from both of these beneficial drug classes. This is a notable change from usual recent practice that limits most patients who actually receive these medications to a drug from just one of these two classes, often because of real or perceived limits on insurance coverage.

The data from these initial patients in the Saint Luke’s CMC show that the program was “very successful; it looks very promising,” said Dr. Kosiborod. The results show “transformational improvement in the quality of care.” Subsequent to this initial cohort from 2019, the Saint Luke’s CMC has seen “hundreds” of additional patients with T2D.
 

The Cardiometabolic Center Alliance gets started

The second member of the Cardiometabolic Center Alliance is a program run by the University Hospitals system based in Cleveland that had begun earlier in 2020. The University Hospitals’ Center for Integrated and Novel Approaches in Vascular-Metabolic Disease (CINEMA) uses a comprehensive, multidisciplinary-care model developed independently of but very similar to the Saint Luke’s CMC. By the end of 2020, the CINEMA program had managed about 150 patients, said Sanjay Rajagopalan, MD, director of CINEMA and a professor of medicine at Case Western Reserve University, Cleveland.

“Our outcomes have been quite similar” to what the Saint Luke’s program reported, he said. “We had better use of guideline-directed therapies, more weight loss, and better control of metabolic parameters.” The CINEMA program entered the Cardiometabolic Center Alliance as a “key strategic partner,” which means it will have a role in shaping the alliance going forward. One issue the alliance faces is how to leverage its growth to improve management of patients with T2D who do not have access to a CMC.

The CMCs “are not meant for every patient with T2D, but for those with high risk for cardiovascular complications who require extra attention,” Dr. Rajagopalan said in an interview. Both he and Dr. Kosiborod acknowledged that, even if 200 CMCs were to eventually open, and even if each center averaged 5,000 managed patients, those 1 million patients would be a small fraction of the total number of U.S. patients with T2D.

“Having these centers will produce a ripple effect. The protocols will percolate to primary care physicians,” Dr. Rajagopalan predicted. Once that happens, “not all patients will need to go to a cardiometabolic center.” In addition, leveraging established protocols via nurse coordinators and virtual care could bring this model to many more patients, Dr. Kosiborod noted.

By the end of 2020, a total of three additional U.S. centers had joined Saint Luke’s and University Hospitals in the alliance, but Dr. Kosiborod said that none of the three had yet been officially announced. The alliance has also started a national cardiometabolic registry, which will be “instrumental for its mission to track, benchmark, and improve quality of care and outcomes; enable mechanisms for “learning health care systems”; and can be used to answer important research questions,” Dr. Kosiborod said.

Combined SGLT2 inhibitor and GLP-1 RA treatment takes off

A key element of the more aggressive, risk-driven management emphasized in the CMC approach is frequent use of combined treatment with an SGLT2 inhibitor and a GLP-1 RA. Both classes of glucose-lowering drugs have well-documented, risk-reducing benefits, notably reduced atherosclerotic cardiovascular events and weight loss produced by the GLP1-RAs, and cuts in heart failure onset and hospitalizations and slowing of chronic kidney disease progression by the SGLT2 inhibitors.

Until now, medical society recommendations as well as opinion leaders have approached these two drug classes with a presumption that physicians would usually prescribe patients an agent from only one of these two classes, largely because the high cost of agents in both classes, all still under patent, often means coverage limits by insurers. Physicians at both the Saint Luke’s and University Hospitals programs have been more proactive, and successful, in prescribing agents from both classes to their high-risk patients with T2D.

“We use combination treatment quite a bit,” said Dr. Kosiborod. “It’s very sensible to use both. Their mechanisms of action are different and likely don’t overlap, so it’s reasonable to presume their activity is complimentary.” But he acknowledged that this has not yet been formally studied for cardiovascular or renal outcomes. Study results have documented complimentary effects between the two classes for weight loss, blood pressure reduction, and to some extent A1c reduction. A key reason for more frequent combined treatment with an SGLT2 inhibitor and GLP-1 RA is increased focus on the ability of both drug classes to lower risk in patients with T2D and high cardiovascular-disease risk, rather than prescribing decisions driven largely by trying to further reduce a patient’s A1c.

Although insurance coverage is not a given, the Saint Luke’s CMC has had good results using patient-assistance programs run by various drug companies. Some patients have received their medications free of charge or with modest copays, depending on their income and insurance coverage. At Saint Luke’s, “many” patients with T2D have been able to get free medications through assistance programs, he said. And for patients with health insurance, getting coverage for an agent from each class “is easier now than it was 3-4 years ago.”

Dr. Kosiborod has been a consultant to several companies, and has received research grants from AstraZeneca and Boehringer Ingelheim. Dr. DeFronzo received research grants from Astra Zeneca, Janssen, and Merck; he has been an adviser to AstraZeneca, Boehringer Ingelheim, Intarcia, Janssen, and Novo Nordisk; and he has been a speaker on behalf of AstraZeneca and Novo Nordisk. Dr. Rajagopalan has been a consultant to Novo Nordisk and Takeda.

Once that happens, “not all patients will need to go to a cardiometabolic center.” In addition, leveraging established protocols via nurse coordinators and virtual care could bring this model to many more patients, Dr. Kosiborod noted.

By the end of 2020, a total of three additional U.S. centers had joined Saint Luke’s and University Hospitals in the alliance, but Dr. Kosiborod said that none of the three had yet been officially announced. The alliance has also started a national cardiometabolic registry, which will be “instrumental for its mission to track, benchmark, and improve quality of care and outcomes; enable mechanisms for “learning health care systems”; and can be used to answer important research questions,” Dr. Kosiborod said.

Combined SGLT2 inhibitor and GLP-1 RA treatment takes off

A key element of the more aggressive, risk-driven management emphasized in the CMC approach is frequent use of combined treatment with an SGLT2 inhibitor and a GLP-1 RA. Both classes of glucose-lowering drugs have well-documented, risk-reducing benefits, notably reduced atherosclerotic cardiovascular events and weight loss produced by the GLP1-RAs, and cuts in heart failure onset and hospitalizations and slowing of chronic kidney disease progression by the SGLT2 inhibitors.

Until now, medical society recommendations as well as opinion leaders have approached these two drug classes with a presumption that physicians would usually prescribe patients an agent from only one of these two classes, largely because the high cost of agents in both classes, all still under patent, often means coverage limits by insurers. Physicians at both the Saint Luke’s and University Hospitals programs have been more proactive, and successful, in prescribing agents from both classes to their high-risk patients with T2D.

“We use combination treatment quite a bit,” said Dr. Kosiborod. “It’s very sensible to use both. Their mechanisms of action are different and likely don’t overlap, so it’s reasonable to presume their activity is complimentary.” But he acknowledged that this has not yet been formally studied for cardiovascular or renal outcomes. Study results have documented complimentary effects between the two classes for weight loss, blood pressure reduction, and to some extent A1c reduction. A key reason for more frequent combined treatment with an SGLT2 inhibitor and GLP-1 RA is increased focus on the ability of both drug classes to lower risk in patients with T2D and high cardiovascular-disease risk, rather than prescribing decisions driven largely by trying to further reduce a patient’s A1c.

Although insurance coverage is not a given, the Saint Luke’s CMC has had good results using patient-assistance programs run by various drug companies. Some patients have received their medications free of charge or with modest copays, depending on their income and insurance coverage. At Saint Luke’s, “many” patients with T2D have been able to get free medications through assistance programs, he said. And for patients with health insurance, getting coverage for an agent from each class “is easier now than it was 3-4 years ago.”

Dr. Kosiborod has been a consultant to several companies, and has received research grants from AstraZeneca and Boehringer Ingelheim. Dr. DeFronzo received research grants from Astra Zeneca, Janssen, and Merck; he has been an adviser to AstraZeneca, Boehringer Ingelheim, Intarcia, Janssen, and Novo Nordisk; and he has been a speaker on behalf of AstraZeneca and Novo Nordisk. Dr. Rajagopalan has been a consultant to Novo Nordisk and Takeda.

A one-stop shop approach to managing the spectrum of complications in patients with type 2 diabetes with a coordinated, multidisciplinary team of clinicians has taken root in at least two U.S. medical centers, and their efforts have now joined to take this concept national through the Cardiometabolic Center Alliance, which hopes to have at least 20 such centers running by the end of 2022.

Doug Brunk/MDedge News

In patients with type 2 diabetes (T2D), “multiple organs are affected by the same disease process,” notably the heart, kidneys, vasculature, and liver, but the care these patients often receive today is “fragmented, and typically without good coordination,” explained Mikhail N. Kosiborod, MD, a cardiologist and codirector of the Saint Luke’s Michael & Marlys Haverty Cardiometabolic Center of Excellence in Kansas City, Mo.

“We need to depart from the outdated idea that each medical specialty focuses on an organ system. It’s one patient with one disease that affects multiple organs and needs comprehensive, multidisciplinary care,” he said.

Historically, “we’ve looked to primary care physicians to ‘conduct the orchestra’ for complex, multispecialty care” for patients with T2D, but a recent “avalanche” of new treatments with new data and recommendations has made coordination by a single, generalist physician essentially impossible. “It isn’t realistic” to expect a single primary care physician to coordinate all the care a patient with T2D now needs to receive, said Dr. Kosiborod, who is also a professor of medicine at the University of Missouri–Kansas City. Plus, “patients can get lost” when they try to navigate on their own among several physicians, possibly in disparate locations, and without fully understanding what each physician is responsible for managing.
 

Application of recommended treatments ‘lagging’

“The data are there, and the recommendations are there for T2D and cardiovascular disease, heart failure, and diabetic kidney disease, but the problem has been implementation,” said Dr. Kosiborod. “Application in practice is lagging way behind the recommendations.” That led him and his associates to devise a “new model of care for patients with T2D,” the cardiometabolic center (CMC), as a status quo alternative.

The CMC paradigm is that patients with T2D, especially those with existing cardiovascular or chronic kidney disease or at high risk for these complications, undergo assessment and treatment at one site from a multidisciplinary staff of physicians and allied caregivers including nurse practitioners, nurse coordinators, pharmacists, dieticians, and diabetes educators who are cross-trained for managing both T2D and cardiovascular diseases.

The Cardiometabolic Center Alliance builds on the idea that this care model is defined by a set of detailed treatment protocols and processes of care that other sites can adopt to boost the number of patients aided by this approach, to gather data from a larger patient pool in a dedicated registry to better document the program’s impact, and to form a quality-improvement network that can collectively improve performance.

“It’s absolutely replicable,” maintained Dr. Kosiborod, who is also executive director of the Cardiometabolic Center Alliance. “We’ve codified all of the care and medications into an impressive package. We now have something that works, and many other centers are interested in building programs like this. By establishing a base of well-defined protocols and operating procedures we can train a cadre of allied professionals who can effectively implement the program across wider populations of patients, while using the brick and mortar center to manage more complex patients,” he added.

“We’re not taking patients” from primary care physicians, Dr. Kosiborod stressed. “We’re helping generalists give better care. They already have their hands full. We’re here to help physicians do better.”

He cited a recent study of 1,735 patients with atherosclerotic cardiovascular disease and diabetes (96% with T2D) enrolled in a registry at 119 U.S. sites during 2016-2018 that found less than 7% were on the full range of guideline-directed medical therapy that they qualified for based on existing treatment guidelines. “This is not acceptable,” Dr. Kosiborod declared.

“It’s so obvious that this needs to be a combined approach. It’s very difficult to have one provider take care of all of the T2D complications. There needs to be a new approach, and [the Cardiometabolic Center program at Saint Luke’s] has done a great job getting their initiative underway to take a more global approach,” commented Ralph A. DeFronzo, MD, chief of the diabetes division and professor of medicine at the University of Texas Health Science Center, San Antonio.
 

Early results show improved metrics

The Saint Luke’s Haverty CMC launched in 2019, and data from its first 129 patients with at least one follow-up visit documented early efficacy for the program, as reported at the American Heart Association’s Quality of Care and Outcome’s Research meeting, held virtually on May 15 and 16, 2020.

That analysis from Dr. Kosiborod and associates compared various short-term metrics among their CMC patients against a control cohort of 387 similar patients with T2D who also received care in the Saint Luke’s Health System during 2019 but outside of the CMC. This observational study involved no patient randomization, but the researchers used propensity scoring to match the control patients with those managed in the CMC by several demographic and clinical parameters.

During follow-up that was generally less than 6 months, patients managed in the CMC averaged 12 pounds of weight loss, a 0.5% reduction in their average hemoglobin A1c, a mean 4.6–mm Hg cut in their systolic blood pressure, an average drop in their LDL cholesterol of 11.4 mg/dL, and among those receiving insulin the daily, average insulin dose fell by a relative 43%, compared with baseline. Among the controls, averages for these five parameters were weight loss of 2 pounds, a cut in A1c of 0.2%, a systolic blood pressure reduction of 0.6 mm Hg, a drop in LDL cholesterol of 4.9 mg/dL, and a relative rise in insulin dose of 6%. All of these between group differences were statistically significant except for LDL cholesterol.

Additional analysis of the medications that patients in the CMC and control group received also showed striking differences. Combined prescriptions for all components of guideline-directed medical therapy went to 41% of the CMC patients, compared with 2% of the controls, a statistically significant difference. Contributing to this difference were significantly increased rates of prescriptions for ACE inhibitors and statins.

The CMC staff also started 57% of their patients on a SGLT2 inhibitor and 90% on a GLP-1 receptor agonist (GLP-1 RA), compared with rates of 18% and 13%, respectively, among controls. Both of these between-group differences were also significant, and they highlighted the willingness and success of the CMC clinicians to put a large number of their patients on agents from both of these beneficial drug classes. This is a notable change from usual recent practice that limits most patients who actually receive these medications to a drug from just one of these two classes, often because of real or perceived limits on insurance coverage.

The data from these initial patients in the Saint Luke’s CMC show that the program was “very successful; it looks very promising,” said Dr. Kosiborod. The results show “transformational improvement in the quality of care.” Subsequent to this initial cohort from 2019, the Saint Luke’s CMC has seen “hundreds” of additional patients with T2D.
 

The Cardiometabolic Center Alliance gets started

The second member of the Cardiometabolic Center Alliance is a program run by the University Hospitals system based in Cleveland that had begun earlier in 2020. The University Hospitals’ Center for Integrated and Novel Approaches in Vascular-Metabolic Disease (CINEMA) uses a comprehensive, multidisciplinary-care model developed independently of but very similar to the Saint Luke’s CMC. By the end of 2020, the CINEMA program had managed about 150 patients, said Sanjay Rajagopalan, MD, director of CINEMA and a professor of medicine at Case Western Reserve University, Cleveland.

“Our outcomes have been quite similar” to what the Saint Luke’s program reported, he said. “We had better use of guideline-directed therapies, more weight loss, and better control of metabolic parameters.” The CINEMA program entered the Cardiometabolic Center Alliance as a “key strategic partner,” which means it will have a role in shaping the alliance going forward. One issue the alliance faces is how to leverage its growth to improve management of patients with T2D who do not have access to a CMC.

The CMCs “are not meant for every patient with T2D, but for those with high risk for cardiovascular complications who require extra attention,” Dr. Rajagopalan said in an interview. Both he and Dr. Kosiborod acknowledged that, even if 200 CMCs were to eventually open, and even if each center averaged 5,000 managed patients, those 1 million patients would be a small fraction of the total number of U.S. patients with T2D.

“Having these centers will produce a ripple effect. The protocols will percolate to primary care physicians,” Dr. Rajagopalan predicted.

Use of sodium-glucose cotransporter 2 (SGLT2) inhibitors during acute COVID-19 illness raises the risk for euglycemic diabetic ketoacidosis (euDKA), a new case series suggests.

Five patients with type 2 diabetes who were taking SGLT2 inhibitors presented in DKA despite having glucose levels below 300 mg/dL. The report was published online last month in AACE Clinical Case Reports by Rebecca J. Vitale, MD, and colleagues at Brigham and Women’s Hospital, Boston.

“A cluster of euglycemic DKA cases at our hospital during the first wave of the pandemic suggests that patients with diabetes taking SGLT2 inhibitors may be at enhanced risk for euDKA when they contract COVID-19,” senior author Naomi D.L. Fisher, MD, said in an interview.

Dr. Fisher, an endocrinologist, added: “This complication is preventable with the simple measure of holding the drug. We are hopeful that widespread patient and physician education will prevent future cases of euDKA as COVID-19 infections continue to surge.”

These cases underscore recommendations published early in the COVID-19 pandemic by an international panel, she noted.

“Patients who are acutely ill with nausea, vomiting, abdominal pain, or diarrhea, or who are experiencing loss of appetite with reduced food and fluid intake, should be advised to hold their SGLT2 inhibitor. This medication should not be resumed until patients are feeling better and eating and drinking normally.”  

On the other hand, “If patients with asymptomatic or mild COVID-19 infection are otherwise well, and are eating and drinking normally, there is no evidence that SGLT2 inhibitors need to be stopped. These patients should monitor [themselves] closely for worsening symptoms, especially resulting in poor hydration and nutrition, which would be reason to discontinue their medication.” 
 

Pay special attention to the elderly, those with complications

However, special consideration should be given to elderly patients and those with medical conditions known to increase the likelihood of severe infection, like heart failure and chronic obstructive pulmonary disease, Dr. Fisher added.

The SGLT2 inhibitor class of drugs causes significant urinary glucose excretion, and they are also diuretics. A decrease in available glucose and volume depletion are probably both important contributors to euDKA, she explained.

With COVID-19 infection the euDKA risk is compounded by several mechanisms. Most cases of euDKA are associated with an underlying state of starvation that can be triggered by vomiting, diarrhea, loss of appetite, and poor oral intake.

In addition – although not yet known for certain – SARS-CoV-2 may also be toxic to pancreatic beta cells and thus reduce insulin secretion. The maladaptive inflammatory response seen with COVID-19 may also contribute, she said.  

The patients in the current case series were three men and two women seen between March and May 2020. They ranged in age from 52 to 79 years.

None had a prior history of DKA or any known diabetes complications. In all of them, antihyperglycemic medications, including SGLT2 inhibitors, were stopped on hospital admission. The patients were initially treated with intravenous insulin, and then subcutaneous insulin after the DKA diagnosis.

Three of the patients were discharged to rehabilitation facilities on hospital days 28-47 and one (age 53 years) was discharged home on day 11. The other patient also had hypertension and nonalcoholic steatohepatitis.

Childhood treatment with recombinant human growth hormone was associated with a significantly increased risk of cardiovascular events, based on data from more than 3,000 individuals.

“Both excess levels of growth hormone and [growth hormone deficiency] have been associated with increased cardiovascular morbidity and mortality,” but data on long-term cardiovascular morbidity in individuals treated with growth hormone in childhood are lacking, wrote Anders Tinblad, MD, of Karolinska Institutet, Stockholm, and colleagues.

In a population-based cohort study published in JAMA Pediatrics, the researchers identified 3,408 Swedish patients treated as children with recombinant human growth hormone (rhGH) between Jan. 1, 1985, and Dec. 31, 2010, and compared each with 15 matched controls (a total of 50,036 controls). The patients were treated for one of three conditions: isolated growth hormone deficiency (GHD), small for gestational age (SGA), and idiopathic short stature (ISS).

Data on cardiovascular outcomes were collected from health care and population-based registers and analyzed between Jan. 1, 1985, and Dec. 31, 2014. The average age of the participants at the study’s end was 25.1 years.

In all, 1,809 cardiovascular disease events were recorded over a median follow-up period of 14.9 years, for an incidence rate of 25.6 events per 10,000 person-years in patients and 22.6 events per 10,000 person-years in controls.

When separated by sex, the incidence was higher in female patients compared with controls (31.2 vs. 23.4 events per 10,000 person-years, respectively, but similar in male patients vs. controls (23.3 vs. 22.3 events per 10,000 person-years). “Differences in estrogen levels or responsiveness to rhGH treatment have previously been hypothesized as possible explanations, but the underlying mechanism for this sex difference still remains unclear and merits further investigation,” the researchers wrote.

Overall, the highest adjusted hazard ratios occurred in subgroups of patients with the longest treatment duration (HR 2.08) and highest cumulative dose of growth hormone (HR 2.05), but no association was noted between highest daily hormone dose and cardiovascular event risk. Hazard ratios were higher across all three treatment subgroups of SGA, GHD, and ISS compared with controls (HR 1.97, 1.66, and 1.55, respectively).

“The association between childhood rhGH treatment and CVD events was also seen when assessing only severe CVD outcomes, but with even lower absolute risks,” the researchers noted.

The study findings were limited by several factors including the potential for confounding by treatment indication and the lack of long-term follow-up data given the relatively young age of the study population, the researchers said. The results were strengthened by the large sample size and showed that the absolute risk for overall and severe cardiovascular disease in children treated with growth hormones was low, “which could be reassuring to individual patients,” they added. However, “At the group level, and perhaps especially for female patients and those treated for SGA indication, further close monitoring and future studies of CVD safety are warranted,” they concluded.
 

Safety and ethical concerns persist

Although the study authors cite limited conclusions on causality and low absolute risk, several issues persist that prompt ongoing analysis of pediatric growth hormone use, namely “worrisome indirect evidence, challenges and limitations in the direct evidence, and the changing world of growth hormone treatment,” Adda Grimberg, MD, of the University of Pennsylvania, Philadelphia, wrote in an accompanying editorial.

“Although evidence asserts that neither growth hormone nor insulinlike growth factor I is carcinogenic, the basic science and oncology literatures are rife with reports showing that they can make aberrant cells more aggressive,” and such indirect evidence supports the need for more direct evidence of possible harm from growth hormone treatment, Dr. Grimberg wrote. Most current safety data on growth hormone come from postmarketing surveillance studies, but these studies do not include controls or data on outcomes after discontinuation of treatment, she noted.

The current study, while able to follow patients across the lifespan, cannot indicate “whether the small but increased risk of cardiovascular disease found in this study was caused by the pediatric growth hormone treatment that identified the participants, by the conditions being treated, by other potential confounder(s) not captured by the study’s methods, or by a combination of the above,” said Dr. Grimberg.

In addition, “the move from replacement of GHD to pharmacologic height augmentation in children who already make sufficient growth hormone had the potential to change the safety profile of treatment,” she said.

“Parents of patients in pediatric primary care practices and of patients seeking growth-related care in a subspecialty endocrine clinic rated treatment characteristics (i.e., proven efficacy and safety) as the factor most having a big or extreme effect on their growth-related medical decision-making,” Dr. Grimberg said. “The centrality of treatment safety to patient-family decision-making underscores the importance of continued scrutiny of growth hormone safety as the treatment and its recipients continue to evolve,” she concluded.

The study was supported by the Swedish Research Council, the Stockholm City Council, the Karolinska Institute, the Society for Child Care, Sahlgrenska University Hospital, and the Stockholm County Council’s combined clinical residency and PhD training program. Lead author Dr. Tidblad disclosed funding from the Society for Child Care and Stockholm County Council during the conduct of the study and personal fees from Pfizer. Dr. Grimberg disclosed serving as a member of the steering committee for the Pfizer International Growth Study Database, and as a consultant for the Pediatric Endocrine Society GH Deficiency Knowledge Center, sponsored by Sandoz AG.

Although the study authors cite limited conclusions on causality and low absolute risk, several issues persist that prompt ongoing analysis of pediatric growth hormone use, namely “worrisome indirect evidence, challenges and limitations in the direct evidence, and the changing world of growth hormone treatment,” Adda Grimberg, MD, of the University of Pennsylvania, Philadelphia, wrote in an accompanying editorial.

“Although evidence asserts that neither growth hormone nor insulinlike growth factor I is carcinogenic, the basic science and oncology literatures are rife with reports showing that they can make aberrant cells more aggressive,” and such indirect evidence supports the need for more direct evidence of possible harm from growth hormone treatment, Dr. Grimberg wrote. Most current safety data on growth hormone come from postmarketing surveillance studies, but these studies do not include controls or data on outcomes after discontinuation of treatment, she noted.

The current study, while able to follow patients across the lifespan, cannot indicate “whether the small but increased risk of cardiovascular disease found in this study was caused by the pediatric growth hormone treatment that identified the participants, by the conditions being treated, by other potential confounder(s) not captured by the study’s methods, or by a combination of the above,” said Dr. Grimberg.

In addition, “the move from replacement of GHD to pharmacologic height augmentation in children who already make sufficient growth hormone had the potential to change the safety profile of treatment,” she said.

“Parents of patients in pediatric primary care practices and of patients seeking growth-related care in a subspecialty endocrine clinic rated treatment characteristics (i.e., proven efficacy and safety) as the factor most having a big or extreme effect on their growth-related medical decision-making,” Dr. Grimberg said. “The centrality of treatment safety to patient-family decision-making underscores the importance of continued scrutiny of growth hormone safety as the treatment and its recipients continue to evolve,” she concluded.

The study was supported by the Swedish Research Council, the Stockholm City Council, the Karolinska Institute, the Society for Child Care, Sahlgrenska University Hospital, and the Stockholm County Council’s combined clinical residency and PhD training program. Lead author Dr. Tidblad disclosed funding from the Society for Child Care and Stockholm County Council during the conduct of the study and personal fees from Pfizer.

Childhood treatment with recombinant human growth hormone was associated with a significantly increased risk of cardiovascular events, based on data from more than 3,000 individuals.

“Both excess levels of growth hormone and [growth hormone deficiency] have been associated with increased cardiovascular morbidity and mortality,” but data on long-term cardiovascular morbidity in individuals treated with growth hormone in childhood are lacking, wrote Anders Tinblad, MD, of Karolinska Institutet, Stockholm, and colleagues.

In a population-based cohort study published in JAMA Pediatrics, the researchers identified 3,408 Swedish patients treated as children with recombinant human growth hormone (rhGH) between Jan. 1, 1985, and Dec. 31, 2010, and compared each with 15 matched controls (a total of 50,036 controls). The patients were treated for one of three conditions: isolated growth hormone deficiency (GHD), small for gestational age (SGA), and idiopathic short stature (ISS).

Data on cardiovascular outcomes were collected from health care and population-based registers and analyzed between Jan. 1, 1985, and Dec. 31, 2014. The average age of the participants at the study’s end was 25.1 years.

In all, 1,809 cardiovascular disease events were recorded over a median follow-up period of 14.9 years, for an incidence rate of 25.6 events per 10,000 person-years in patients and 22.6 events per 10,000 person-years in controls.

When separated by sex, the incidence was higher in female patients compared with controls (31.2 vs. 23.4 events per 10,000 person-years, respectively, but similar in male patients vs. controls (23.3 vs. 22.3 events per 10,000 person-years). “Differences in estrogen levels or responsiveness to rhGH treatment have previously been hypothesized as possible explanations, but the underlying mechanism for this sex difference still remains unclear and merits further investigation,” the researchers wrote.

Overall, the highest adjusted hazard ratios occurred in subgroups of patients with the longest treatment duration (HR 2.08) and highest cumulative dose of growth hormone (HR 2.05), but no association was noted between highest daily hormone dose and cardiovascular event risk. Hazard ratios were higher across all three treatment subgroups of SGA, GHD, and ISS compared with controls (HR 1.97, 1.66, and 1.55, respectively).

“The association between childhood rhGH treatment and CVD events was also seen when assessing only severe CVD outcomes, but with even lower absolute risks,” the researchers noted.

The study findings were limited by several factors including the potential for confounding by treatment indication and the lack of long-term follow-up data given the relatively young age of the study population, the researchers said. The results were strengthened by the large sample size and showed that the absolute risk for overall and severe cardiovascular disease in children treated with growth hormones was low, “which could be reassuring to individual patients,” they added. However, “At the group level, and perhaps especially for female patients and those treated for SGA indication, further close monitoring and future studies of CVD safety are warranted,” they concluded.

The pandemic has isolated our patients to an unprecedented degree, forcing them to find other ways to communicate with us, including email. I wondered how private offices were handling the marked increase in email communications since the pandemic began; so I queried several physician blogs and social media pages.

Responses varied all over the map. Some refuse the medium entirely. “I politely say that I don’t practice dermatology via email,” said one. “Please schedule a teledermatology appointment and I’d be happy to help.”

Others are ambivalent: “I do email with some patients who have complex situations or quick questions, but if it gets out of hand then I let them know someone will call to make an appointment.” Another office treats them as a one-way street: “We set up one account to receive patients’ emails, but we tell them clearly that we don’t respond ... my staff or I call them back.”

Still others have assimilated it completely. “Patients email through the portal and my MA routes [them] to me. I answer questions and the MA responds ... staff loves it because it’s so much faster than the phone.”

A 1998 study in JAMA was more scientifically designed, but basically reached the same conclusion. The authors found “a striking lack of consensus” on how to deal with patient emails: 50% responded to them, but 31% of responders refused to give advice without seeing the patient, while 59% offered a diagnosis, and a third of that group went on to provide specific advice about therapy. In response to a follow-up questionnaire, 28% said that they tended not to answer any patient emails, 24% said they usually replied with a standard message, and 24% said they answer each request individually. The authors concluded that “standards for physician response to unsolicited patient emails are needed.”

Indeed, my own unscientific survey suggests that, more than 20 years later, there is still nothing resembling a consensus on this issue. In the interim, several groups, including the American Medical Informatics Association and the American Medical Association have proposed standards, but none have been generally accepted. Until that happens, it seems prudent for each individual practice to adopt its own guidelines. For ideas, take a look at the proposals from the groups I mentioned, plus any others you can find. When you’re done, consider running your list past your attorney to make sure you haven’t forgotten anything, and that there are no unique requirements in your state.

Your guidelines may be very simple (if you decide never to answer any queries) or very complex, depending on your situation and personal philosophy. But all guidelines should cover such issues as authentication of correspondents, informed consent, licensing jurisdiction (if you receive emails from states in which you are not licensed), and of course, confidentiality.

Contrary to popular belief, HIPAA does not prohibit email communication with patients, nor require that it be encrypted. The HIPAA website specifically says: “Patients may initiate communications with a provider using email. If this situation occurs, the health care provider can assume (unless the patient has explicitly stated otherwise) that e-mail communications are acceptable to the individual.”

Still, if you are not comfortable with unencrypted communication, encryption software can be added to your practice’s email system. Proofpoint, Tumbleweed, Zix, and many other vendors sell encryption packages. (As always, I have no financial interest in any product or enterprise mentioned in this column.)

Another option is web-based messaging: Patients enter your website and send a message using an electronic template that you design. A designated staffer will be notified by regular email when messages are received, and can post a reply on a page that can only be accessed by the patient. Besides enhancing privacy and security, you can state your guidelines in plain English to preclude any misunderstanding of what you will and will not address online.

Web-based messaging services can be freestanding or incorporated into existing secure websites. Medfusion and klara are among the leading vendors of secure messaging services.

The important thing is to make a firm decision on how you want to deal with emails, and stick with that method. And follow your guidelines.

A scoring system that predicts risk for new heart failure over 5 years that is based solely on a few familiar, readily available biomarkers could potentially help steer patients with diabetes or even prediabetes toward HF-preventive therapies, researchers proposed based on a new study.

They foresee the risk-stratification tool, based on data pooled from three major community-based cohort studies but not independently validated, as a way to select patients with diabetes and prediabetes for treatment with SGLT2 inhibitors.

Several members of that drug class, conceived as antidiabetic agents, have been shown to help in prevention or treatment of HF in patients with diabetes and those without diabetes but at increased cardiovascular (CV) risk. Yet their uptake in practice has been lagging, the group noted.

Most HF benefits in the SGLT2 inhibitor trials “were seen in patients who have established cardiovascular disease – basically a history of heart attack or stroke,” Ambarish Pandey, MD, MSCS, University of Texas Southwestern Medical Center, Dallas, said in an interview.

“So we wanted to see how we can identify high-risk patients without a history of cardiovascular disease using these biomarkers, as an approach to targeting SGLT2 inhibitors, which are fairly expensive therapies,” he said. Without such risk stratification, “you end up treating so many more patients to get very modest returns.”

The group developed a scoring system based on four biomarkers that are “easily measured with inexpensive tests,” Dr. Pandey said: high-sensitivity-assay cardiac troponin T (hs-cTnT) and C-reactive protein (hs-CRP) levels, N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) levels, and electrocardiography for evidence of left-ventricular hypertrophy (ECG-LVH).

The derivation cohort consisted of participants in the Atherosclerosis Risk in Communities RIC, Dallas Heart Study, and Multi-Ethnic Study of Atherosclerosis Multi-Ethnic Study of Atherosclerosis epidemiologic studies who were free of coronary heart disease, stroke, or HF for whom there were sufficient data on CV risk factors and the four biomarkers. None were taking SGLT2 inhibitors at enrollment in their respective studies, the researchers noted.

Members of the pooled cohorts who had diabetes or prediabetes were assigned 1 point for each abnormal biomarker. The 5-year risk for incident HF went up continuously along with the score in people with diabetes and in those with prediabetes, the latter defined as a fasting plasma glucose level from 100 mg/dL to less than 126 mg/dL.

For those with a score of 1, compared with 0, for example, the risk for HF went up 82% with diabetes and 40% with prediabetes. But for those with a score of 3 or 4, the risk went up more than four and a half times with diabetes and more than three and a half times for those with prediabetes. Risk increases were independent of other likely HF risk factors and consistently significant.

The analysis was published Jan. 6 in JACC: Heart Failure.

The biomarker score should be especially useful in patients considered at low to intermediate risk, based on clinical characteristics, as a means to identify residual HF risk and, potentially, select candidates for SGLT2-inhibitor therapy, Dr. Pandey said.

“The other purpose of the study was to broaden the scope of heart failure prevention in dysglycemia by looking also at prediabetes, not just diabetes,” he said. There isn’t much high-quality evidence supporting SGLT2-inhibitor therapy in prediabetes, but it follows that the drugs may be helpful in prediabetes because they are protective in patients with and without diabetes.

“Our work suggests that prediabetes patients who have elevated biomarkers are at a higher risk of heart failure,” Dr. Pandey said, suggesting that the HF risk score could potentially help select their drug therapy as well.

The current study seems “to provide a proof of concept that one can use circulating biomarkers to more precisely identify patients in whom therapies might be expected to exert greatest benefit,” which is especially important for potentially expensive agents like the SGLT2 inhibitors, James L. Januzzi, MD, Massachusetts General Hospital, Boston, said in an interview.

Importantly in the analysis, a greater number of biomarker abnormalities not only corresponded to rising levels of risk, the risk increases were “dramatic,” and therefore so was the supposed potential benefit of SGLT2-inhibitor therapy, said Dr. Januzzi, who isn’t a coauthor but was an editor for its publication in JACC: Heart Failure.

The uptake of SGLT2 inhibitors for heart failure in practice has been less rapid than hoped, he observed, so if “this hypothetical construct holds up” for the drug class, “it might actually help kick-start focusing on who might optimally receive the drugs.”

Elevated levels of hs-cTnT, hs-CRP, and NT-proBNP, as well as presence of ECG-LVH, were each independently associated with a significantly increased 5-year risk for HF in unadjusted and adjusted analyses of the 6,799 people in the pooled cohort, 33.2% of whom had diabetes and 66.8% of whom had prediabetes, the group writes.

The scoring system would require validation in other cohorts before it could be used, Dr. Pandey observed; once there is “robust validation,” it might be applied first to patients with dysglycemia at intermediate CV risk by standard clinical measures.

Certainly the HF risk-stratification scoring system requires validation in other studies, Dr. Januzzi agreed. But it is intuitively appealing, and the study’s results are consistent with “data that we’re submitting for publication imminently” based on the CANVAS CV-outcomes trial of the SGLT2 inhibitor canagliflozin (Invokana) in patients with diabetes.

Dr. Pandey disclosed receiving support from the Gilead Sciences Research Scholar Program and serving on an advisory board of Roche Diagnostics. Dr. Januzzi disclosed receiving grant support from Novartis, Applied Therapeutics, and Innolife; consulting for Abbott Diagnostics, Janssen, Novartis, Quidel, and Roche Diagnostics; and serving on end-point committees or data safety monitoring boards for trials supported by Abbott, AbbVie, Amgen, CVRx, Janssen, MyoKardia, and Takeda.

The biomarker score should be especially useful in patients considered at low to intermediate risk, based on clinical characteristics, as a means to identify residual HF risk and, potentially, select candidates for SGLT2-inhibitor therapy, Dr. Pandey said.

“The other purpose of the study was to broaden the scope of heart failure prevention in dysglycemia by looking also at prediabetes, not just diabetes,” he said. There isn’t much high-quality evidence supporting SGLT2-inhibitor therapy in prediabetes, but it follows that the drugs may be helpful in prediabetes because they are protective in patients with and without diabetes.

“Our work suggests that prediabetes patients who have elevated biomarkers are at a higher risk of heart failure,” Dr. Pandey said, suggesting that the HF risk score could potentially help select their drug therapy as well.

The current study seems “to provide a proof of concept that one can use circulating biomarkers to more precisely identify patients in whom therapies might be expected to exert greatest benefit,” which is especially important for potentially expensive agents like the SGLT2 inhibitors, James L. Januzzi, MD, Massachusetts General Hospital, Boston, said in an interview.

Importantly in the analysis, a greater number of biomarker abnormalities not only corresponded to rising levels of risk, the risk increases were “dramatic,” and therefore so was the supposed potential benefit of SGLT2-inhibitor therapy, said Dr. Januzzi, who isn’t a coauthor but was an editor for its publication in JACC: Heart Failure.

The uptake of SGLT2 inhibitors for heart failure in practice has been less rapid than hoped, he observed, so if “this hypothetical construct holds up” for the drug class, “it might actually help kick-start focusing on who might optimally receive the drugs.”

Elevated levels of hs-cTnT, hs-CRP, and NT-proBNP, as well as presence of ECG-LVH, were each independently associated with a significantly increased 5-year risk for HF in unadjusted and adjusted analyses of the 6,799 people in the pooled cohort, 33.2% of whom had diabetes and 66.8% of whom had prediabetes, the group writes.

The scoring system would require validation in other cohorts before it could be used, Dr. Pandey observed; once there is “robust validation,” it might be applied first to patients with dysglycemia at intermediate CV risk by standard clinical measures.

Certainly the HF risk-stratification scoring system requires validation in other studies, Dr. Januzzi agreed. But it is intuitively appealing, and the study’s results are consistent with “data that we’re submitting for publication imminently” based on the CANVAS CV-outcomes trial of the SGLT2 inhibitor canagliflozin (Invokana) in patients with diabetes.

Dr. Pandey disclosed receiving support from the Gilead Sciences Research Scholar Program and serving on an advisory board of Roche Diagnostics. Dr. Januzzi disclosed receiving grant support from Novartis, Applied Therapeutics, and Innolife; consulting for Abbott Diagnostics, Janssen, Novartis, Quidel, and Roche Diagnostics; and serving on end-point committees or data safety monitoring boards for trials supported by Abbott, AbbVie, Amgen, CVRx, Janssen, MyoKardia, and Takeda.

The list of things to be ungrateful for last year is long. You’re not supposed to make this list, though. The best practice is to list what you’re grateful for, even when living in trying times. That’s a long list too, but I find making it similarly unfruitful.

Of course, I’m grateful I don’t have COVID-19, thankful my practice hasn’t been significantly impacted, grateful I got the vaccine. But simply repeating these gratitudes daily seems ineffective. I’ve learned a different “gratefulness practice” that perhaps works better.

The last question is the best. We all spend time thinking about what others think of us. We should spend time thinking about what impact we’ve had on them. Like a cold shower, it’s both briskly awakening and easy to do. Go back through your day and reflect on what you did that made things difficult for others. It can be as simple as I started whining about how a patient waylaid me with her silly complaints. That led to my colleague’s joining in about difficult patients. Or I was late turning in my article, which made my editor have to work harder to get it completed in time.

There’s plenty of things we should be grateful for. In doing these exercises you’ll learn just how much others have cared for you and, I hope, how you might do things to make them grateful for you.

If you’re interested in learning more about Naikan, I discovered this from Brett McKay’s The Art of Manliness podcast and the teaching of Gregg Krech, summarized in his book, “Naikan: Gratitude, Grace, and the Japanese Art of Self-Reflection.”

A single injection of denosumab (Prolia, Amgen), frequently used to treat osteoporosis, may reduce the need for revision surgery in patients with symptomatic osteolysis following total hip arthroplasty, a new proof-of-concept study suggests.

Aseptic loosening is the result of wear-induced osteolysis caused by the prosthetic hip and is a major contributor to the need for revision surgery in many parts of the world.

“The only established treatment for prosthesis-related osteolysis after joint replacement is revision surgery, which carries substantially greater morbidity and mortality than primary joint replacement,” Mohit M. Mahatma, MRes, of the University of Sheffield, England, and colleagues wrote in their article, published online Jan. 11 in The Lancet Rheumatology.

As well as an increased risk of infection and other complications, revision surgery is much more costly than a first-time operation, they added.

“The results of this proof-of-concept clinical trial indicate that denosumab is effective at reducing bone resorption activity within osteolytic lesion tissue and is well tolerated within the limitations of the single dose used here,” they concluded.

Commenting on the findings, Antonia Chen, MD, associate professor of orthopedic surgery, Harvard Medical School, Boston, emphasized that further studies are needed to assess the effectiveness of this strategy to reduce the need for hip revision surgery.

Nevertheless, “osteolysis is still unfortunately a problem we do have to deal with and we do not have any other way to prevent it,” she said in an interview. “So it’s a good start ... although further studies are definitely needed,” Dr. Chen added.

In an accompanying editorial, Hannu Aro, MD, Turku University Hospital in Finland, agreed: “Without a doubt, the trial is a breakthrough, but it represents only the first step in the development of pharmacological therapy aiming to slow, prevent, or even reverse the process of wear-induced periprosthetic osteolysis.”
 

Small single-center study

The phase 2, single-center, randomized, controlled trial involved 22 patients who had previously undergone hip replacement surgery at Sheffield Teaching Hospitals and were scheduled for revision surgery due to symptomatic osteolysis. They were randomized to a single subcutaneous injection of denosumab at a dose of 60 mg, or placebo, on their second hospital visit.

“The primary outcome was the between-group difference in the number of osteoclasts per mm of osteolytic membrane at the osteolytic membrane-bone interface at week 8,” the authors noted.

At this time point, there were 83% fewer osteoclasts at the interface in the denosumab group compared with placebo, at a median of 0.05 per mm in the treatment group compared with 0.30 per mm in the placebo group (P = .011). 

Secondary histological outcomes were also significantly improved in favor of the denosumab group compared with placebo.
 

Potential to prevent half of all hip revision surgeries?

Patients who received denosumab also demonstrated an acute fall in serum and urinary markers of bone resorption following administration of the drug, reaching a nadir at week 4, which was maintained until revision surgery at week 8.

In contrast, “no change in these markers was observed in the placebo group [P < .0003 for all biomarkers],” the investigators noted. Rates of adverse events were comparable in both treatment groups.

As the authors explained, osteolysis occurs following joint replacement surgery when particles of plastic wear off from the prosthesis, triggering an immune reaction that attacks the bone around the implant, causing the joint to loosen.

“It is very clear from our bone biopsies and bone imaging that the [denosumab] injection stops the bone absorbing the microplastic particles from the replacement joint and therefore could prevent the bone from being eaten away and the need for revision surgery,” senior author Mark Wilkinson, MBChB, PhD, honorary consultant orthopedic surgeon, Sheffield Teaching Hospitals, said in a press release from his institution.

“This study is a significant breakthrough as we’ve demonstrated that there is a drug, already available and successful in the treatment of osteoporosis, that has the potential to prevent up to half of all revised replacement surgeries which are caused by osteolysis,” he added.

Dr. Wilkinson and coauthors said their results justify the need for future trials targeting earlier-stage disease to further test the use of denosumab to prevent or reduce the need for revision surgery.

In 2018, aseptic loosening accounted for over half of all revision procedures, as reported to the National Joint Registry in England and Wales.
 

Older polyethylene prostheses are the main culprit

Commenting further on the study, Dr. Chen noted that osteolysis still plagues orthopedic surgeons because the original polyethylene prostheses were not very good. A better prosthesis developed at Massachusetts General Hospital is made up of highly crossed-link polyethylene and still wears over time but to a much lesser extent than the older polyethylene prostheses.

Metal and ceramic prostheses also can induce osteolysis, but again to a much lesser extent than the older polyethylene implants.

“Any particle can technically cause osteolysis but plastic produces the most particles,” Dr. Chen explained. Although hip revision rates in the United States are low to begin with, aseptic loosening is still one of the main reasons that patients need to undergo revision surgery, she observed.

“A lot of patients are still living with the old plastic [implants] so there is still a need for something like this,” she stressed.

However, many questions about this potential new strategy remain to be answered, including when best to initiate treatment and how to manage patients at risk for osteolysis 20-30 years after they have received their original implant.

In his editorial, Dr. Aro said that serious adverse consequences often become evident 10-20 years after patients have undergone the original hip replacement procedures, when they are potentially less physically fit than they were at the time of the operation and thus less able to withstand the rigors of a difficult revision surgery.

“In this context, the concept of nonsurgical pharmacological treatment of periprosthetic osteolysis ... brings a new hope for the ever-increasing population of patients with total hip arthroplasty to avoid revision surgery,” Dr. Aro suggested.

However, Dr. Aro cautioned that reduction of bone turnover by antiresorptive agents such as denosumab has been associated with the development of atypical femoral fractures.

The study was funded by Amgen. Dr. Wilkinson has reported receiving a grant from Amgen. Dr. Chen has reported serving as a consultant for Striker and b-One Ortho. Dr. Aro has reported receiving a grant to his institution from Amgen Finland and the Academy of Finland. He has also served as a member of an advisory scientific board for Amgen Finland.

When Margot Gage-Witvliet began feeling run down after her family returned from a trip to the Netherlands in late February 2020, she initially chalked up her symptoms to jet lag. Three days later, however, her situation went from concerning to alarming as she struggled to breathe. “It felt like there was an elephant sitting on my chest,” she said.

Her husband and daughters also became ill with COVID-19, but Ms. Gage-Witvliet was the only one in her family who didn’t get better. After an early improvement, a rare coronavirus-induced tonic-clonic seizure in early April sent her spiraling back down. Ms. Gage-Witvliet spent the next several weeks in bed with the curtains drawn, unable to tolerate light or sound.

Today, Ms. Gage-Witvliet’s life looks nothing like it did 6 months ago when she first got sick. As one of COVID-19’s so called long-haulers, she continues to struggle with crushing fatigue, brain fog, and headaches – symptoms that worsen when she pushes herself to do more. Across the country, as many as 1 in 10 COVID-19 patients are reporting illnesses that continue for weeks and months after their initial diagnosis. Nearly all report neurologic issues like Ms. Gage-Witvliet, as well as shortness of breath and psychiatric concerns.

For Avindra Nath, MD, a neurologist at the National Institutes of Health, the experience of these long-haul COVID-19 patients feels familiar and reminds him of myalgic encephalomyelitis, also known as chronic fatigue syndrome.

Dr. Nath has long been interested in the lingering neurologic issues connected to chronic fatigue. An estimated three-quarters of all patients with chronic fatigue syndrome report that their symptoms started after a viral infection, and they suffer unrelenting exhaustion, difficulties regulating pulse and blood pressure, aches and pains, and brain fog. When Dr. Nath first read about the novel coronavirus, he began to worry that the virus would trigger symptoms in a subset of those infected. Hearing about the experiences of long-haulers like Ms. Gage-Witvliet raised his suspicions even more.

Unlike COVID-19 long-haulers, however, many patients with chronic fatigue syndrome go at least a year with these symptoms before receiving a diagnosis, according to a British survey. That means researchers have had few opportunities to study the early stages of the syndrome. “When we see patients with myalgic encephalomyelitis, whatever infection they might have had occurred in the remote past, so there’s no way for us to know how they got infected with it, what the infection was, or what the effects of it were in that early phase. We’re seeing them 2 years afterward,” Dr. Nath said.

Dr. Nath quickly realized that studying patients like Ms. Gage-Witvliet would give physicians and scientists a unique opportunity to understand not only long-term outcomes of COVID-19 infections, but also other postviral syndromes, including chronic fatigue syndrome at their earliest stages. It’s why Dr. Nath has spent the past several months scrambling to launch two NIH studies to examine the phenomenon.

Although Dr. Nath said that the parallels between COVID-19 long-haulers and those with chronic fatigue syndrome are obvious, he cautions against assuming that they are the same phenomenon. Some long-haulers might simply be taking a much slower path to recovery, or they might have a condition that looks similar on the surface but differs from chronic fatigue syndrome on a molecular level. But even if Dr. Nath fails to see links to chronic fatigue syndrome, with more than 92.5 million documented cases of COVID-19 around the world, the work will be relevant to the substantial number of infected individuals who don’t recover quickly.

“With so many people having exposure to the same virus over a similar time period, we really have the opportunity to look at these manifestations and at the very least to understand postviral syndromes,” said Mady Hornig, MD, a psychiatrist at Columbia University, New York.

The origins of chronic fatigue syndrome date back to 1985, when the Centers for Disease Control and Prevention received a request from two physicians – Paul Cheney, MD, and Daniel Peterson, MD – to investigate a mysterious disease outbreak in Nevada. In November 1984, residents in and around the idyllic vacation spot of Incline Village, a small town tucked into the north shore of Lake Tahoe, had begun reporting flu-like symptoms that persisted for weeks, even months. The doctors had searched high and low for a cause, but they couldn’t figure out what was making their patients sick.

They reported a range of symptoms – including muscle aches and pains, low-grade fevers, sore throats, and headaches – but everyone said that crippling fatigue was the most debilitating issue. This wasn’t the kind of fatigue that could be cured by a nap or even a long holiday. No matter how much their patients slept – and some were almost completely bedbound – their fatigue didn’t abate. What’s more, the fatigue got worse whenever they tried to push themselves to do more. Puzzled, the CDC sent two epidemic intelligence service (EIS) officers to try to get to the bottom of what might be happening.


 

Muscle aches and pains with crippling fatigue

After their visit to Incline Village, however, the CDC was just as perplexed as Dr. Cheney and Dr. Peterson. Many of the people with the condition reported flu-like symptoms right around the time they first got sick, and the physicians’ leading hypothesis was that the outbreak and its lasting symptoms were caused by chronic Epstein-Barr virus infection. But neither the CDC nor anyone else could identify the infection or any other microbial cause. The two EIS officers duly wrote up a report for the CDC’s flagship publication, Morbidity and Mortality Weekly ReportI, titled “Chronic Fatigue Possibly Related to Epstein-Barr Virus – Nevada”.

That investigators focused on the fatigue aspect made sense, says Leonard A. Jason, PhD, professor of psychology at DePaul University and director of the Center for Community Research, both in Chicago, because it was one of the few symptoms shared by all the individuals studied and it was also the most debilitating. But that focus – and the name “chronic fatigue syndrome” – led to broad public dismissal of the condition’s severity, as did an editorial note in MMWR urging physicians to look for “more definable, and possibly treatable, conditions.” Subsequent research failed to confirm a specific link to the Epstein-Barr virus, which only added to the condition’s phony reputation. Rather than being considered a potentially disabling illness, it was disregarded as a “yuppie flu” or a fancy name for malingering.

“It’s not a surprise that patients are being dismissed because there’s already this sort of grandfathered-in sense that fatigue is not real,” said Jennifer Frankovich, MD, a pediatric rheumatologist at Stanford (Calif.) University’s Lucile Packard Children’s Hospital in Palo Alto. “I’m sure that’s frustrating for them to be tired and then to have the clinician not believe them or dismiss them or think they’re making it up. It would be more helpful to the families to say: ‘You know what, we don’t know, we do not have the answer, and we believe you.’ ”
 

A syndrome’s shame

As time passed, patient advocacy groups began pushing back against the negative way the condition was being perceived. This criticism came as organizations like the CDC worked to develop a set of diagnostic criteria that researchers and clinicians dealing with chronic fatigue syndrome could use. With such a heterogeneous group of patients and symptoms, the task was no small challenge. The discussions, which took place over nearly 2 decades, played a key role in helping scientists home in on the single factor that was central to chronic fatigue: postexertional malaise.

“This is quite unique for chronic fatigue syndrome. With other diseases, yes, you may have fatigue as one of the components of the disease, but postexertional fatigue is very specific,” said Alain Moreau, PhD, a molecular biologist at the University of Montreal.

Of course, plenty of people have pushed themselves too hard physically and paid the price the next day. But those with chronic fatigue syndrome weren’t running marathons. To them, exertion could be anything from getting the mail to reading a book. Nor could the resulting exhaustion be resolved by an afternoon on the couch or a long vacation.

“If they do these activities, they can crash for weeks, even months,” Dr. Moreau said. It was deep, persistent, and – for 40% of those with chronic fatigue syndrome – disabling. In 2015, a study group from the Institute of Medicine proposed renaming chronic fatigue to “systemic exercise intolerance disease” because of the centrality of this symptom. Although that effort mostly stalled, their report did bring the condition out of its historic place as a scientific backwater. What resulted was an uptick in research on chronic fatigue syndrome, which helped define some of the physiological issues that either contribute to or result from the condition.

Researchers had long known about the link between infection and fatigue, said Dr. Frankovich. Work included mysterious outbreaks like the one in Lake Tahoe and well-documented issues like the wave of encephalitis lethargica (a condition that leaves patients in an almost vegetative state) that followed the 1918 H1N1 influenza pandemic.

“As a clinician, when you see someone who comes in with a chronic infection, they’re tired. I think that’s why, in the chronic-fatigue world, people are desperately looking for the infection so we can treat it, and maybe these poor suffering people will feel better,” Dr. Frankovich added. Then the pandemic struck, giving him yet another opportunity to study postviral syndromes.
 

Immunologic symptoms

Given the close link between a nonspecific viral illness and the onset of symptoms in chronic fatigue syndrome, scientists like Dr. Hornig opted to focus on immunologic symptoms. In a 2015 analysis published in Science, Dr. Hornig and colleagues showed that immune problems can be found in the earliest stages of chronic fatigue syndrome, and that they change as the illness progresses. Patients who had been sick for less than 3 years showed significant increases in levels of both pro- and anti-inflammatory cytokines, and the factor most strongly correlated to this inability to regulate cytokine levels was the duration of symptoms, not their severity. A series of other studies also revealed problems with regulation of the immune system, although no one could show what might have set these problems in motion.

Other researchers found signs of mitochondrial dysfunction in those with chronic fatigue syndrome. Because mitochondria make energy for cells, it wasn’t an intellectual stretch to believe that glitches in this process could contribute to fatigue. As early as 1991, scientists had discovered signs of mitochondrial degeneration in muscle biopsies from people with chronic fatigue syndrome. Subsequent studies showed that those affected by chronic fatigue were missing segments of mitochondrial DNA and had significantly reduced levels of mitochondrial activity. Although exercise normally improves mitochondrial functioning, the opposite appears to happen in chronic fatigue.

To Dr. Nath, these dual hypotheses aren’t necessarily mutually exclusive. Some studies have hinted that infection with the common human herpesvirus–6 (HHV-6) can lead to an autoimmune condition in which the body makes antibodies against the mitochondria. Mitochondria also play a key role in the ability of the innate immune system to produce interferon and other proinflammatory cytokines. It might also be that the link between immune and mitochondrial problems is more convoluted than originally thought, or that the two systems are affected independent of one another, Dr. Nath said.

Finding answers, especially those that could lead to potential treatments, wouldn’t be easy, however. In 2016, the NIH launched an in-depth study of a small number of individuals with chronic fatigue, hoping to find clues about what the condition was and how it might be treated.

For scientists like Dr. Nath, the NIH study provided a way to get at the underlying biology of chronic fatigue syndrome. Then the pandemic struck, giving him yet another opportunity to study postviral syndromes.
 

Chronic post-SARS syndrome

In March 2020, retired physician Harvey Moldofsky, MD, began receiving inquiries about a 2011 study he and his colleague, John Patcai, MD, had published in BMC Neurology about something they dubbed “chronic post-SARS syndrome.” The small case-control study, which involved mainly health care workers in Toronto, received little attention when it was first published, but with COVID-19, it was suddenly relevant.

Early clusters of similar cases in Miami made local physicians desperate for Dr. Moldofsky’s expertise. Luckily, he was nearby; he had fled the frigid Canadian winter for the warmth of Sarasota, Fla.

“I had people from various countries around the world writing to me and asking what they should do. And of course I don’t have any answers,” he said. But the study contained one of the world’s only references to the syndrome.

In 2003, a woman arrived in Toronto from Hong Kong. She didn’t know it at the time, but her preairport stay at the Hotel Metropole had infected her with the first SARS (severe acute respiratory syndrome) coronavirus. Her subsequent hospitalization in Toronto sparked a city-wide outbreak of SARS in which 273 people became ill and 44 died. Many of those affected were health care workers, including nurses and respiratory therapists. Although most eventually returned to work, a subset couldn’t. They complained of energy-sapping fatigue, poor sleep, brain fog, and assorted body aches and pains that persisted for more than 18 months. The aches and pains brought them to the attention of Dr. Moldofsky, then director of the Centre for the Study of Pain at the University of Toronto.

His primary interest at the time was fibromyalgia, which caused symptoms similar to those reported by the original SARS long-haulers. Intrigued, Dr. Moldofsky agreed to take a look. Their chest x-rays were clear and the nurses showed no signs of lingering viral infection. Dr. Moldofsky could see that the nurses were ill and suffering, but no lab tests or anything else could identify what was causing their symptoms.

In 2011, Dr. Moldofsky and Dr. Patcai found a strong overlap between chronic SARS, fibromyalgia, and chronic fatigue syndrome when they compared 22 patients with long-term SARS issues with 21 who had fibromyalgia. “Their problems are exactly the same. They have strange symptoms and nobody can figure out what they’re about. And these symptoms are aches and pains, and they have trouble thinking and concentrating,” Dr. Moldofsky said. Reports of COVID-19 long-haulers didn’t surprise Dr. Moldofsky, and he immediately recognized that Nath’s intention to follow these patients could provide insights into both fibromyalgia and chronic fatigue syndrome.

That’s exactly what Dr. Nath is proposing with the two NIH studies. One will focus solely on the neurologic impacts of COVID-19, including stroke, loss of taste and smell, and brain fog. The other will bring patients who have had COVID-19 symptoms for at least 6 months to the NIH Clinical Center for an inpatient stay during which they will undergo detailed physiologic tests.

Scientists around the world are launching their own post–COVID-19 studies. Dr. Moreau’s group in Montreal has laid the groundwork for such an endeavor, and the CoroNerve group in the United Kingdom is monitoring neurologic complications from the coronavirus. Many of them have the same goals as the NIH studies: Leverage the large number of COVID-19 long-haulers to better understand the earliest stages of postviral syndrome.

“At this juncture, after all the reports that we’ve seen so far, I think it’s very unlikely that there will be no relationship whatsoever between COVID-19 and chronic fatigue syndrome,” Dr. Hornig said. “I think there certainly will be some, but again, what’s the scope, what’s the size? And then, of course, even more importantly, if it is happening, what is the mechanism and how is it happening?”

For people like Ms. Gage-Witvliet, the answers can’t come soon enough. For the first time in more than a decade, the full-time professor of epidemiology didn’t prepare to teach this year because she simply can’t. It’s too taxing for her brain to deal with impromptu student questions. Ms. Gage-Witvliet hopes that, by sharing her own experiences with post COVID-19, she can help others.

“In my work, I use data to give a voice to people who don’t have a voice,” she said. “Now, I am one of those people.”

When Margot Gage-Witvliet began feeling run down after her family returned from a trip to the Netherlands in late February 2020, she initially chalked up her symptoms to jet lag. Three days later, however, her situation went from concerning to alarming as she struggled to breathe. “It felt like there was an elephant sitting on my chest,” she said.

Her husband and daughters also became ill with COVID-19, but Ms. Gage-Witvliet was the only one in her family who didn’t get better. After an early improvement, a rare coronavirus-induced tonic-clonic seizure in early April sent her spiraling back down. Ms. Gage-Witvliet spent the next several weeks in bed with the curtains drawn, unable to tolerate light or sound.

Today, Ms. Gage-Witvliet’s life looks nothing like it did 6 months ago when she first got sick. As one of COVID-19’s so called long-haulers, she continues to struggle with crushing fatigue, brain fog, and headaches – symptoms that worsen when she pushes herself to do more. Across the country, as many as 1 in 10 COVID-19 patients are reporting illnesses that continue for weeks and months after their initial diagnosis. Nearly all report neurologic issues like Ms. Gage-Witvliet, as well as shortness of breath and psychiatric concerns.

For Avindra Nath, MD, a neurologist at the National Institutes of Health, the experience of these long-haul COVID-19 patients feels familiar and reminds him of myalgic encephalomyelitis, also known as chronic fatigue syndrome.

Dr. Nath has long been interested in the lingering neurologic issues connected to chronic fatigue. An estimated three-quarters of all patients with chronic fatigue syndrome report that their symptoms started after a viral infection, and they suffer unrelenting exhaustion, difficulties regulating pulse and blood pressure, aches and pains, and brain fog. When Dr. Nath first read about the novel coronavirus, he began to worry that the virus would trigger symptoms in a subset of those infected. Hearing about the experiences of long-haulers like Ms. Gage-Witvliet raised his suspicions even more.

Unlike COVID-19 long-haulers, however, many patients with chronic fatigue syndrome go at least a year with these symptoms before receiving a diagnosis, according to a British survey. That means researchers have had few opportunities to study the early stages of the syndrome. “When we see patients with myalgic encephalomyelitis, whatever infection they might have had occurred in the remote past, so there’s no way for us to know how they got infected with it, what the infection was, or what the effects of it were in that early phase. We’re seeing them 2 years afterward,” Dr. Nath said.

Dr. Nath quickly realized that studying patients like Ms. Gage-Witvliet would give physicians and scientists a unique opportunity to understand not only long-term outcomes of COVID-19 infections, but also other postviral syndromes, including chronic fatigue syndrome at their earliest stages. It’s why Dr. Nath has spent the past several months scrambling to launch two NIH studies to examine the phenomenon.

Although Dr. Nath said that the parallels between COVID-19 long-haulers and those with chronic fatigue syndrome are obvious, he cautions against assuming that they are the same phenomenon. Some long-haulers might simply be taking a much slower path to recovery, or they might have a condition that looks similar on the surface but differs from chronic fatigue syndrome on a molecular level. But even if Dr. Nath fails to see links to chronic fatigue syndrome, with more than 92.5 million documented cases of COVID-19 around the world, the work will be relevant to the substantial number of infected individuals who don’t recover quickly.

“With so many people having exposure to the same virus over a similar time period, we really have the opportunity to look at these manifestations and at the very least to understand postviral syndromes,” said Mady Hornig, MD, a psychiatrist at Columbia University, New York.

The origins of chronic fatigue syndrome date back to 1985, when the Centers for Disease Control and Prevention received a request from two physicians – Paul Cheney, MD, and Daniel Peterson, MD – to investigate a mysterious disease outbreak in Nevada. In November 1984, residents in and around the idyllic vacation spot of Incline Village, a small town tucked into the north shore of Lake Tahoe, had begun reporting flu-like symptoms that persisted for weeks, even months. The doctors had searched high and low for a cause, but they couldn’t figure out what was making their patients sick.

They reported a range of symptoms – including muscle aches and pains, low-grade fevers, sore throats, and headaches – but everyone said that crippling fatigue was the most debilitating issue. This wasn’t the kind of fatigue that could be cured by a nap or even a long holiday. No matter how much their patients slept – and some were almost completely bedbound – their fatigue didn’t abate. What’s more, the fatigue got worse whenever they tried to push themselves to do more. Puzzled, the CDC sent two epidemic intelligence service (EIS) officers to try to get to the bottom of what might be happening.


 

Muscle aches and pains with crippling fatigue

After their visit to Incline Village, however, the CDC was just as perplexed as Dr. Cheney and Dr. Peterson. Many of the people with the condition reported flu-like symptoms right around the time they first got sick, and the physicians’ leading hypothesis was that the outbreak and its lasting symptoms were caused by chronic Epstein-Barr virus infection. But neither the CDC nor anyone else could identify the infection or any other microbial cause. The two EIS officers duly wrote up a report for the CDC’s flagship publication, Morbidity and Mortality Weekly ReportI, titled “Chronic Fatigue Possibly Related to Epstein-Barr Virus – Nevada”.

That investigators focused on the fatigue aspect made sense, says Leonard A. Jason, PhD, professor of psychology at DePaul University and director of the Center for Community Research, both in Chicago, because it was one of the few symptoms shared by all the individuals studied and it was also the most debilitating. But that focus – and the name “chronic fatigue syndrome” – led to broad public dismissal of the condition’s severity, as did an editorial note in MMWR urging physicians to look for “more definable, and possibly treatable, conditions.” Subsequent research failed to confirm a specific link to the Epstein-Barr virus, which only added to the condition’s phony reputation. Rather than being considered a potentially disabling illness, it was disregarded as a “yuppie flu” or a fancy name for malingering.

“It’s not a surprise that patients are being dismissed because there’s already this sort of grandfathered-in sense that fatigue is not real,” said Jennifer Frankovich, MD, a pediatric rheumatologist at Stanford (Calif.) University’s Lucile Packard Children’s Hospital in Palo Alto. “I’m sure that’s frustrating for them to be tired and then to have the clinician not believe them or dismiss them or think they’re making it up. It would be more helpful to the families to say: ‘You know what, we don’t know, we do not have the answer, and we believe you.’ ”

A series of other studies also revealed problems with regulation of the immune system, although no one could show what might have set these problems in motion.

Other researchers found signs of mitochondrial dysfunction in those with chronic fatigue syndrome. Because mitochondria make energy for cells, it wasn’t an intellectual stretch to believe that glitches in this process could contribute to fatigue. As early as 1991, scientists had discovered signs of mitochondrial degeneration in muscle biopsies from people with chronic fatigue syndrome. Subsequent studies showed that those affected by chronic fatigue were missing segments of mitochondrial DNA and had significantly reduced levels of mitochondrial activity. Although exercise normally improves mitochondrial functioning, the opposite appears to happen in chronic fatigue.

To Dr. Nath, these dual hypotheses aren’t necessarily mutually exclusive. Some studies have hinted that infection with the common human herpesvirus–6 (HHV-6) can lead to an autoimmune condition in which the body makes antibodies against the mitochondria. Mitochondria also play a key role in the ability of the innate immune system to produce interferon and other proinflammatory cytokines. It might also be that the link between immune and mitochondrial problems is more convoluted than originally thought, or that the two systems are affected independent of one another, Dr. Nath said.

Finding answers, especially those that could lead to potential treatments, wouldn’t be easy, however. In 2016, the NIH launched an in-depth study of a small number of individuals with chronic fatigue, hoping to find clues about what the condition was and how it might be treated.

For scientists like Dr. Nath, the NIH study provided a way to get at the underlying biology of chronic fatigue syndrome. Then the pandemic struck, giving him yet another opportunity to study postviral syndromes.
 

Chronic post-SARS syndrome

In March 2020, retired physician Harvey Moldofsky, MD, began receiving inquiries about a 2011 study he and his colleague, John Patcai, MD, had published in BMC Neurology about something they dubbed “chronic post-SARS syndrome.” The small case-control study, which involved mainly health care workers in Toronto, received little attention when it was first published, but with COVID-19, it was suddenly relevant.

Early clusters of similar cases in Miami made local physicians desperate for Dr. Moldofsky’s expertise. Luckily, he was nearby; he had fled the frigid Canadian winter for the warmth of Sarasota, Fla.

“I had people from various countries around the world writing to me and asking what they should do. And of course I don’t have any answers,” he said. But the study contained one of the world’s only references to the syndrome.

In 2003, a woman arrived in Toronto from Hong Kong. She didn’t know it at the time, but her preairport stay at the Hotel Metropole had infected her with the first SARS (severe acute respiratory syndrome) coronavirus. Her subsequent hospitalization in Toronto sparked a city-wide outbreak of SARS in which 273 people became ill and 44 died. Many of those affected were health care workers, including nurses and respiratory therapists. Although most eventually returned to work, a subset couldn’t. They complained of energy-sapping fatigue, poor sleep, brain fog, and assorted body aches and pains that persisted for more than 18 months. The aches and pains brought them to the attention of Dr. Moldofsky, then director of the Centre for the Study of Pain at the University of Toronto.

His primary interest at the time was fibromyalgia, which caused symptoms similar to those reported by the original SARS long-haulers. Intrigued, Dr. Moldofsky agreed to take a look. Their chest x-rays were clear and the nurses showed no signs of lingering viral infection. Dr. Moldofsky could see that the nurses were ill and suffering, but no lab tests or anything else could identify what was causing their symptoms.

In 2011, Dr. Moldofsky and Dr. Patcai found a strong overlap between chronic SARS, fibromyalgia, and chronic fatigue syndrome when they compared 22 patients with long-term SARS issues with 21 who had fibromyalgia. “Their problems are exactly the same. They have strange symptoms and nobody can figure out what they’re about. And these symptoms are aches and pains, and they have trouble thinking and concentrating,” Dr. Moldofsky said. Reports of COVID-19 long-haulers didn’t surprise Dr. Moldofsky, and he immediately recognized that Nath’s intention to follow these patients could provide insights into both fibromyalgia and chronic fatigue syndrome.

That’s exactly what Dr. Nath is proposing with the two NIH studies. One will focus solely on the neurologic impacts of COVID-19, including stroke, loss of taste and smell, and brain fog. The other will bring patients who have had COVID-19 symptoms for at least 6 months to the NIH Clinical Center for an inpatient stay during which they will undergo detailed physiologic tests.

Scientists around the world are launching their own post–COVID-19 studies. Dr. Moreau’s group in Montreal has laid the groundwork for such an endeavor, and the CoroNerve group in the United Kingdom is monitoring neurologic complications from the coronavirus. Many of them have the same goals as the NIH studies: Leverage the large number of COVID-19 long-haulers to better understand the earliest stages of postviral syndrome.

“At this juncture, after all the reports that we’ve seen so far, I think it’s very unlikely that there will be no relationship whatsoever between COVID-19 and chronic fatigue syndrome,” Dr. Hornig said. “I think there certainly will be some, but again, what’s the scope, what’s the size? And then, of course, even more importantly, if it is happening, what is the mechanism and how is it happening?”

For people like Ms. Gage-Witvliet, the answers can’t come soon enough. For the first time in more than a decade, the full-time professor of epidemiology didn’t prepare to teach this year because she simply can’t. It’s too taxing for her brain to deal with impromptu student questions. Ms. Gage-Witvliet hopes that, by sharing her own experiences with post COVID-19, she can help others.

“In my work, I use data to give a voice to people who don’t have a voice,” she said. “Now, I am one of those people.”
