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 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.

“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.

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.

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.”

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 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.

Among the multiple vaccine candidates around the globe, next up in the arsenal against COVID-19 is likely the single-dose Ad26.COV2.S vaccine in development from Johnson & Johnson/Janssen, infectious disease experts predict.

And it got closer with promising interim phase 1/2a trial results, published online Jan. 13 in The New England Journal of Medicine.

A single Ad26.COV2.S dose was associated with S-binding and neutralizing antibodies in more than 90% of the participants. The finding was observed in both adults aged 18-55 years and participants 65 and older, as well as for participants given low-dose or high-dose vaccinations.

The results also suggest a durable vaccine response. “The take-home message [includes] a high neutralizing antibody responder rate to a single dose of our Ad26.COV2.S COVID-19 vaccine candidate. In addition, we see that these responses and antibody titers are stable for at least 71 days,” senior study author Hanneke Schuitemaker, PhD, global head of viral vaccine discovery and translational medicine at Johnson & Johnson in Leiden, the Netherlands, said in an interview.

If the single-dose Johnson & Johnson product gains Food and Drug Administration emergency use authorization (EUA), it could significantly boost the number of overall immunizations available. Less stringent storage requirements – only regular refrigeration vs. a need to freeze the Pfizer/BioNTech and Moderna COVID-19 vaccines – is another potential advantage. The Ad26.COV2.S vaccine can be refrigerated for up to 3 months at 36°-46 °F (2°-8 °C).

“Phase 1-2 trial data on the J&J vaccine: If it works as well as the mRNA options, it will have substantial advantages,” Jeremy Faust, MD, an emergency room physician affiliated with Brigham & Women’s Hospital and Harvard Medical School, Boston, tweeted on Jan. 13.

Unlike the Pfizer/BioNTech and Moderna messenger RNA vaccines, the Johnson & Johnson product is a recombinant, replication-incompetent adenovirus serotype 26 (Ad26) vector encoding a full-length and stabilized SARS-CoV-2 spike (S) protein.
 

Phase 3 efficacy/safety results pending

Under normal circumstances, phase 3 trial results would not be anticipated within weeks of phase 1/2a trial findings. However, the urgency of the COVID-19 pandemic accelerated the vaccine development process, so preclinical trials were conducted simultaneously and not sequentially. For this reason, phase 3 interim results for the Johnson & Johnson vaccine are expected within weeks, and a company executive told Reuters that the rollout is on track for March.

“We hope to report data from our first phase 3 study, ENSEMBLE, in which we are testing the protective efficacy of a single dose of Ad26.COV2.S, by the end of this month or early February,” Dr. Schuitemaker said. 

In the meantime, the phase 1/2a ongoing, multicenter, randomized, double-blind, and placebo-controlled trial interim results have drawn positive reactions.

“Data is highly encouraging and supports the single inoculation approach that makes this vaccine unique,” Carlos del Rio, executive associate dean for Emory University at Grady in Atlanta, wrote in a tweet on Jan. 13.

“Encouraging COVID vaccine data from J&J published [Jan. 13]. Solid antibody, CD4 T cell, and CD8 T cell responses – a nice trifecta of vaccine immune responses to see! And safe!” tweeted Shane Crotty, PhD, vaccine scientist and professor at the La Jolla (Calif.) Institute for Immunology.

 

First results in 800+ participants

At baseline for the phase 1/2a trial, 2% of the younger group and 1% of the 65+ group were seropositive for SARS-CoV-2 S-specific antibodies.

A total of 402 people in the younger age cohort and 403 in the 65 and older group received a first dose of the Johnson & Johnson vaccine. Many participants also received a second dose 56 days later for a separate trial, ENSEMBLE2, designed to compare safety and efficacy between single- and double-dose regimens. Results of that trial are still pending.
 

Safety profile

A single dose was associated with a higher incidence of solicited systemic adverse events in the higher vaccine dose group. They also found that grade 3 adverse events decreased with increasing age.

Injection site pain on the day of immunization or the next day was the most common local reaction. The pain generally resolved within 24 hours. Fever was reported by 15% of the low-dose vaccine group and 39% of the high-dose cohort. Fatigue, headache, and myalgia were the most common grade 1 or 2 solicited systemic adverse events reported.

Five serious adverse events were reported, including four that investigators deemed unrelated to vaccination: hypotension, bilateral nephrolithiasis, legionella pneumonia, and one case of worsening of multiple sclerosis. The vaccine-related serious adverse event was a fever that resulted in hospitalization because of suspicion of COVID-19. The patient recovered within 12 hours.

“These data confirm our previous experience with vaccine candidates based on our Ad26 viral vector platform in the younger age group. The almost similar performance in older adults is promising,” Dr. Schuitemaker said.

A potential limitation of the phase 1/2a trial is “the lack of representation of minority groups,” the researchers noted. Johnson & Johnson is working on improving the diversity of study participants “with respect to groups that seem to be affected most by the COVID-19 pandemic.”
 

AstraZeneca/Oxford vaccine status

The AstraZeneca/Oxford AZD1222 vaccine in development received approval for use in the United Kingdom on Dec. 30. The approval came after Public Health England said the country was facing “unprecedented” levels of infections, the BBC reported. AstraZeneca applied for European Medical Agency approval earlier in the week of Jan. 10, which could lead to more widespread use across Europe.

The status of the vaccine remains uncertain in the United States. A phase 3 trial that started in August was paused for about 6 weeks in September and October after an adverse event in a British volunteer halted studies worldwide. On Oct. 23, the FDA permitted researchers to continue the trial with approximately 40,000 participants.

There was some suggestion in the clinical trials that a half dose of the AstraZeneca vaccine was more effective than a full dose, 90% vs. 62%, but some irregularities in the research require further investigation.

Although the AstraZeneca vaccine is delivered to cells by an adenovirus – as with the Johnson & Johnson product – it is designed to be delivered in two doses 28 days apart, like the administration schedule of the Moderna mRNA vaccine.
 

A need for speed, and more doses

Regardless of which vaccine product is next to gain an EUA in the United States, many experts agree the COVID-19 vaccine rollouts so far have been problematic, at a time when cases are climbing to record-breaking levels, and likely more related to logistics over administration of the vaccine than production of the doses.

“Lots of doses being manufactured. In December 20 million, January 40 million, February 80 million and J&J hopefully soon to add to the count. The shortage is the number arms not getting vaccinated. Freezers do not get COVID. They do not need all those vaccines,” Daniel Griffin, MD, PhD, an infectious disease expert in Port Washington, N.Y., tweeted on Jan. 12.

“Unfortunately, the rollout has not gone smoothly, partly due to a lack of resources for this distribution phase we’re in,” Andrew T. Pavia, MD, chief of the division of pediatric infectious diseases at the University of Utah, Salt Lake City, said during a media briefing Jan. 14 sponsored by the Infectious Diseases Society of America (IDSA).

“We’re concerned about the mismatch between the number of people who are being told they are eligible and the amount of vaccine that is being distributed,” he said.

Complicating the rollout is a directive from U.S. Health and Human Services Secretary Alex Azar that states should start vaccinating everyone 65 and older as well as those with underlying conditions.

Expanding distribution to the 15% of Americans in just this age group is a big challenge, Dr. Pavia said. “We have enough vaccine maybe to vaccinate 40 million by the end of this month. There is a huge disconnect, and that creates a lot of problems.”

“One of the biggest problems is we are trying to do this mass vaccination program in the middle of the biggest surge we’ve ever seen,” Julie Vaishampayan, MD, MPH, chair of the IDSA Public Health Committee, said during the briefing. Without sufficient time for public health officials to plan for vaccinating a larger population, “people will come and stand in extremely long lines.”

Trying to expand immunization access without a proportionate increase in available doses prompted Dr. Vaishampayan to share an analogy from a colleague: “We are trying to fill a lake with a garden hose. Rather than making the lake bigger, what we really need is more water.”

Dr. Pavia emphasized that infectious disease experts “know the measures that work.” Not using masks, physical distancing, and hand hygiene, he said, “is a bit like knowing that really good shark repellents will be available in summer, so I’m going to jump into the ocean covered in blood while the great whites are swimming around.”

An official at the World Health Organization agreed. “Vaccines are coming online and I do believe vaccines will make a huge difference. But they are not here yet in enough quantities and in enough people to make that difference,” Michael Ryan, MB, WHO executive director of health emergencies, said during an online media briefing Jan. 13, held in conjunction with Emory University.

Dr. Ryan predicted that “we’ve got weeks if not months ahead of us in which our weapon is our knowledge ... what we know about this virus, its transmission, and stopping that transmission.

“And as the vaccines roll in, we can hopefully end this horrific pandemic.”

Dr. Schuitemaker reports grants from BARDA during the conduct of the study; personal fees and other from Janssen Vaccines and Prevention, a J&J company, outside the submitted work. Johnson & Johnson and the Biomedical Advanced Research and Development Authority of the Department of Health and Human Services funded the phase 1/2a study.

“Encouraging COVID vaccine data from J&J published [Jan. 13]. Solid antibody, CD4 T cell, and CD8 T cell responses – a nice trifecta of vaccine immune responses to see! And safe!” tweeted Shane Crotty, PhD, vaccine scientist and professor at the La Jolla (Calif.) Institute for Immunology.

 

First results in 800+ participants

At baseline for the phase 1/2a trial, 2% of the younger group and 1% of the 65+ group were seropositive for SARS-CoV-2 S-specific antibodies.

A total of 402 people in the younger age cohort and 403 in the 65 and older group received a first dose of the Johnson & Johnson vaccine. Many participants also received a second dose 56 days later for a separate trial, ENSEMBLE2, designed to compare safety and efficacy between single- and double-dose regimens. Results of that trial are still pending.
 

Safety profile

A single dose was associated with a higher incidence of solicited systemic adverse events in the higher vaccine dose group. They also found that grade 3 adverse events decreased with increasing age.

Injection site pain on the day of immunization or the next day was the most common local reaction. The pain generally resolved within 24 hours. Fever was reported by 15% of the low-dose vaccine group and 39% of the high-dose cohort. Fatigue, headache, and myalgia were the most common grade 1 or 2 solicited systemic adverse events reported.

Five serious adverse events were reported, including four that investigators deemed unrelated to vaccination: hypotension, bilateral nephrolithiasis, legionella pneumonia, and one case of worsening of multiple sclerosis. The vaccine-related serious adverse event was a fever that resulted in hospitalization because of suspicion of COVID-19. The patient recovered within 12 hours.

“These data confirm our previous experience with vaccine candidates based on our Ad26 viral vector platform in the younger age group. The almost similar performance in older adults is promising,” Dr. Schuitemaker said.

A potential limitation of the phase 1/2a trial is “the lack of representation of minority groups,” the researchers noted. Johnson & Johnson is working on improving the diversity of study participants “with respect to groups that seem to be affected most by the COVID-19 pandemic.”
 

AstraZeneca/Oxford vaccine status

The AstraZeneca/Oxford AZD1222 vaccine in development received approval for use in the United Kingdom on Dec. 30. The approval came after Public Health England said the country was facing “unprecedented” levels of infections, the BBC reported. AstraZeneca applied for European Medical Agency approval earlier in the week of Jan. 10, which could lead to more widespread use across Europe.

The status of the vaccine remains uncertain in the United States. A phase 3 trial that started in August was paused for about 6 weeks in September and October after an adverse event in a British volunteer halted studies worldwide. On Oct. 23, the FDA permitted researchers to continue the trial with approximately 40,000 participants.

There was some suggestion in the clinical trials that a half dose of the AstraZeneca vaccine was more effective than a full dose, 90% vs. 62%, but some irregularities in the research require further investigation.

Although the AstraZeneca vaccine is delivered to cells by an adenovirus – as with the Johnson & Johnson product – it is designed to be delivered in two doses 28 days apart, like the administration schedule of the Moderna mRNA vaccine.
 

A need for speed, and more doses

Regardless of which vaccine product is next to gain an EUA in the United States, many experts agree the COVID-19 vaccine rollouts so far have been problematic, at a time when cases are climbing to record-breaking levels, and likely more related to logistics over administration of the vaccine than production of the doses.

“Lots of doses being manufactured. In December 20 million, January 40 million, February 80 million and J&J hopefully soon to add to the count. The shortage is the number arms not getting vaccinated. Freezers do not get COVID. They do not need all those vaccines,” Daniel Griffin, MD, PhD, an infectious disease expert in Port Washington, N.Y., tweeted on Jan. 12.

“Unfortunately, the rollout has not gone smoothly, partly due to a lack of resources for this distribution phase we’re in,” Andrew T. Pavia, MD, chief of the division of pediatric infectious diseases at the University of Utah, Salt Lake City, said during a media briefing Jan. 14 sponsored by the Infectious Diseases Society of America (IDSA).

“We’re concerned about the mismatch between the number of people who are being told they are eligible and the amount of vaccine that is being distributed,” he said.

Complicating the rollout is a directive from U.S. Health and Human Services Secretary Alex Azar that states should start vaccinating everyone 65 and older as well as those with underlying conditions.

Expanding distribution to the 15% of Americans in just this age group is a big challenge, Dr. Pavia said. “We have enough vaccine maybe to vaccinate 40 million by the end of this month. There is a huge disconnect, and that creates a lot of problems.”

“One of the biggest problems is we are trying to do this mass vaccination program in the middle of the biggest surge we’ve ever seen,” Julie Vaishampayan, MD, MPH, chair of the IDSA Public Health Committee, said during the briefing. Without sufficient time for public health officials to plan for vaccinating a larger population, “people will come and stand in extremely long lines.”

Trying to expand immunization access without a proportionate increase in available doses prompted Dr. Vaishampayan to share an analogy from a colleague: “We are trying to fill a lake with a garden hose. Rather than making the lake bigger, what we really need is more water.”

Dr. Pavia emphasized that infectious disease experts “know the measures that work.” Not using masks, physical distancing, and hand hygiene, he said, “is a bit like knowing that really good shark repellents will be available in summer, so I’m going to jump into the ocean covered in blood while the great whites are swimming around.”

An official at the World Health Organization agreed. “Vaccines are coming online and I do believe vaccines will make a huge difference. But they are not here yet in enough quantities and in enough people to make that difference,” Michael Ryan, MB, WHO executive director of health emergencies, said during an online media briefing Jan. 13, held in conjunction with Emory University.

Dr. Ryan predicted that “we’ve got weeks if not months ahead of us in which our weapon is our knowledge ... what we know about this virus, its transmission, and stopping that transmission.

“And as the vaccines roll in, we can hopefully end this horrific pandemic.”

Dr. Schuitemaker reports grants from BARDA during the conduct of the study; personal fees and other from Janssen Vaccines and Prevention, a J&J company, outside the submitted work. Johnson & Johnson and the Biomedical Advanced Research and Development Authority of the Department of Health and Human Services funded the phase 1/2a study.

Among the multiple vaccine candidates around the globe, next up in the arsenal against COVID-19 is likely the single-dose Ad26.COV2.S vaccine in development from Johnson & Johnson/Janssen, infectious disease experts predict.

And it got closer with promising interim phase 1/2a trial results, published online Jan. 13 in The New England Journal of Medicine.

A single Ad26.COV2.S dose was associated with S-binding and neutralizing antibodies in more than 90% of the participants. The finding was observed in both adults aged 18-55 years and participants 65 and older, as well as for participants given low-dose or high-dose vaccinations.

The results also suggest a durable vaccine response. “The take-home message [includes] a high neutralizing antibody responder rate to a single dose of our Ad26.COV2.S COVID-19 vaccine candidate. In addition, we see that these responses and antibody titers are stable for at least 71 days,” senior study author Hanneke Schuitemaker, PhD, global head of viral vaccine discovery and translational medicine at Johnson & Johnson in Leiden, the Netherlands, said in an interview.

If the single-dose Johnson & Johnson product gains Food and Drug Administration emergency use authorization (EUA), it could significantly boost the number of overall immunizations available. Less stringent storage requirements – only regular refrigeration vs. a need to freeze the Pfizer/BioNTech and Moderna COVID-19 vaccines – is another potential advantage. The Ad26.COV2.S vaccine can be refrigerated for up to 3 months at 36°-46 °F (2°-8 °C).

“Phase 1-2 trial data on the J&J vaccine: If it works as well as the mRNA options, it will have substantial advantages,” Jeremy Faust, MD, an emergency room physician affiliated with Brigham & Women’s Hospital and Harvard Medical School, Boston, tweeted on Jan. 13.

Unlike the Pfizer/BioNTech and Moderna messenger RNA vaccines, the Johnson & Johnson product is a recombinant, replication-incompetent adenovirus serotype 26 (Ad26) vector encoding a full-length and stabilized SARS-CoV-2 spike (S) protein.
 

Phase 3 efficacy/safety results pending

Under normal circumstances, phase 3 trial results would not be anticipated within weeks of phase 1/2a trial findings. However, the urgency of the COVID-19 pandemic accelerated the vaccine development process, so preclinical trials were conducted simultaneously and not sequentially. For this reason, phase 3 interim results for the Johnson & Johnson vaccine are expected within weeks, and a company executive told Reuters that the rollout is on track for March.

“We hope to report data from our first phase 3 study, ENSEMBLE, in which we are testing the protective efficacy of a single dose of Ad26.COV2.S, by the end of this month or early February,” Dr. Schuitemaker said. 

In the meantime, the phase 1/2a ongoing, multicenter, randomized, double-blind, and placebo-controlled trial interim results have drawn positive reactions.

“Data is highly encouraging and supports the single inoculation approach that makes this vaccine unique,” Carlos del Rio, executive associate dean for Emory University at Grady in Atlanta, wrote in a tweet on Jan. 13.

The American Diabetes Association, along with 18 other organizations, has sent a letter to the U.S. Centers for Disease Control and Prevention urging them to rank people with type 1 diabetes as equally high risk for COVID-19 severity, and therefore vaccination, as those with type 2 diabetes.

On Jan. 12, the CDC recommended states vaccinate all Americans over age 65 and those with underlying health conditions that make them more vulnerable to COVID-19.

Currently, type 2 diabetes is listed among 12 conditions that place adults “at increased risk of severe illness from the virus that causes COVID-19,” with the latter defined as “hospitalization, admission to the intensive care unit, intubation or mechanical ventilation, or death.”

On the other hand, the autoimmune condition type 1 diabetes is among 11 conditions the CDC says “might be at increased risk” for COVID-19, but limited data were available at the time of the last update on Dec. 23, 2020.

“States are utilizing the CDC risk classification when designing their vaccine distribution plans. This raises an obvious concern as it could result in the approximately 1.6 million with type 1 diabetes receiving the vaccination later than others with the same risk,” states the ADA letter, sent to the CDC on Jan. 13.

Representatives from the Endocrine Society, American Association of Clinical Endocrinology, Pediatric Endocrine Society, Association of Diabetes Care & Education Specialists, and JDRF, among others, cosigned the letter.
 

Newer data show those with type 1 diabetes at equally high risk

While acknowledging that “early data did not provide as much clarity about the extent to which those with type 1 diabetes are at high risk,” the ADA says newer evidence has emerged, as previously reported by this news organization, that “convincingly demonstrates that COVID-19 severity is more than tripled in individuals with type 1 diabetes.”

The letter also cites another study showing that people with type 1 diabetes “have a 3.3-fold greater risk of severe illness, are 3.9 times more likely to be hospitalized with COVID-19, and have a 3-fold increase in mortality compared to those without type 1 diabetes.”

Those risks, they note, are comparable to the increased risk established for those with type 2 diabetes, as shown in a third study from Scotland, published last month.

Asked for comment, CDC representative Kirsten Nordlund said in an interview, “This list is a living document that will be periodically updated by CDC, and it could rapidly change as the science evolves.”

In addition, Ms. Nordlund said, “Decisions about transitioning to subsequent phases should depend on supply; demand; equitable vaccine distribution; and local, state, or territorial context.”

“Phased vaccine recommendations are meant to be fluid and not restrictive for jurisdictions. It is not necessary to vaccinate all individuals in one phase before initiating the next phase; phases may overlap,” she noted. More information is available here.
 

Tennessee gives type 1 and type 2 diabetes equal priority for vaccination

Meanwhile, at least one state, Tennessee, has updated its guidance to include both types of diabetes as being priority for COVID-19 vaccination.

Vanderbilt University pediatric endocrinologist Justin M. Gregory, MD, said in an interview: “I was thrilled when our state modified its guidance on December 30th to include both type 1 and type 2 diabetes in the ‘high-risk category.’ Other states have not modified that guidance though.”

It’s unclear how this might play out on the ground, noted Dr. Gregory, who led one of the three studies demonstrating increased COVID-19 risk for people with type 1 diabetes.

“To tell you the truth, I don’t really know how individual organizations dispensing the vaccination [will handle] people who come to their facility saying they have ‘diabetes.’ Individual states set the vaccine-dispensing guidance and individual county health departments and health care systems mirror that guidance,” he said.

Thus, he added, “Although it’s possible an individual nurse may take the ‘I’ll ask you no questions, and you’ll tell me no lies’ approach if someone with type 1 diabetes says they have ‘diabetes’, websites and health department–recorded telephone messages are going to tell people with type 1 diabetes they have to wait further back in line if that is what their state’s guidance directs.”

“Kidney disease is the most common chronic disease in the United States and the world, and the incidence is on the rise,” said Kim Zuber, PA-C, executive director of the American Academy of Nephrology PAs and outreach chair for the National Kidney Foundation in St. Petersburg, Fla.

Kidney disease also is an expensive problem that accounts for approximately 20% of the Medicare budget in the United States, she said in a virtual presentation at the Metabolic & Endocrine Disease Summit by Global Academy for Medical Education.

“It’s important that we know how to identify it and how to slow the progression if possible, and what to do when we can no longer control the disease,” she said.

Notably, the rate of growth for kidney disease is highest among adults aged 20-45 years, said Ms. Zuber. “That is the group who will live for many years with kidney disease,” but should be in their peak years of working and earning. “That is the group we do not want to develop chronic diseases.”

“Look for kidney disease. It’s not always on the chart; it is often missed because people don’t think of it,” Ms. Zuber said. Anyone over 60 years has likely lost some kidney function. Other risk factors include minority/ethnicity, hypertension or cardiovascular disease, diabetes, and a family history of kidney disease.

Women are more likely to develop chronic kidney disease (CKD), but less likely to go on dialysis, said Ms. Zuber. “What I find fascinating is that a history of oophorectomy” increases risk. Other less obvious risk factors in a medical history that should prompt a kidney disease screening include mothers who drank during pregnancy, individuals with a history of acute kidney disease, lupus, sarcoid, amyloid, gout, or other autoimmune conditions, as well as a history of kidney stones of cancer. Kidney donors or transplant recipients are at increased risk, as are smokers, soda drinkers, and heavy salt users.

CKD is missed by many health care providers, Ms. Zuber said. For example, she cited data from more than 270,000 veterans treated at a Veterans Affairs hospital in Texas, which suggested that the likelihood of adding CKD to a patient’s diagnosis was 43.7% even if lab results confirmed CKD.
 

Find the patients

There are many formulas for defining kidney function, Ms. Zuber said. The estimation of creatinine clearance (eCrCl) and estimated glomerular filtration rate (eGFR) are among them. The most common definition is to calculate eGFR using the CKD-EPI formula. Cystatin C is more exact, but it is not standardized, so a lab in one state does not use the same formula as one in another state.

Overall, all these formulas are plus or minus 30%. “It is an estimate,” she said. Within the stages of CKD, “what we know is that, if you have a high GFR, that’s good, but patients who are losing albumin are at increased risk for CKD.” The albumin is more of a risk factor for CKD than GFR, so the GFR test used doesn’t make much difference, whereas, “if you have a lot of albumin in your urine, you are going downhill,” she said.

Normally, everyone loses kidney function with age, Ms. Zuber said. Starting at age 30, individuals lose about 1 mL/min per year in measures of GFR, however, this progression is more rapid among those with CKD, so “we need to find those people who are progressing more quickly than normal.”

The way to identify the high-risk patients is albumin, Ms. Zuber said. Health care providers need to test the urine and check albumin for high levels of albumin loss through urine, and many providers simply don’t routinely conduct urine tests for patients with other CKD risk factors such as diabetes or hypertension.

Albuminuria levels of 2,000 mg/g are the most concerning, and a urine-albumin-to-creatinine ratio (UACR) test is the most effective tool to monitor kidney function, Ms. Zuber said.

She recommends ordering a UACR test at least once a year to monitor kidney loss in all patients with hypertension, diabetes, lupus, and other risk factors including race and a history of acute kidney injury.
 

Keep them healthy

Managing patients with chronic kidney disease includes attention to several categories: hypertension, diabetes, obesity, and cardiovascular disease, and mental health, Ms. Zuber said.

“If hypertension doesn’t cause your CKD, your CKD will cause hypertension,” she said. The goal for patients with CKD is a target systolic blood pressure less than 120 mm Hg. “As kidney disease progresses, hypertension becomes harder to control,” she added. Lifestyle changes including exercise, low-fat diet, limited use of salt, weight loss if needed, and stress reduction strategies can help.

For patients with diabetes and CKD, work towards a target hemoglobin A1c of 7.0 for early CKD, and of 8% for stage 4/5 or for older patients with multiple comorbidities, Ms. Zuber said. All types of insulin are safe for CKD patients. “Kidney function declines at twice the normal rate for diabetes patients; however, SGLT2 inhibitors are very renoprotective. You may not see a drop in A1c, but you are protecting the kidney.”

For patients with obesity and CKD, data show that bariatric surgery (gastric bypass) lowers mortality in diabetes and also protects the heart and kidneys, said Ms. Zuber. Overall, central obesity increases CKD risk independent of any other risk factors, but losing weight, either by surgery or diet/lifestyle, helps save the kidneys.

Cardiovascular disease is the cause of death for more than 70% of kidney disease patients, Ms. Zuber said. CKD patients “are two to three times more likely to have atrial fibrillation, so take the time to listen with that stethoscope,” she added, also emphasizing the importance of statins for all CKD and diabetes patients, and decreasing smoking. In addition, “managing metabolic acidosis slows the loss of kidney function and protects the heart.”

Additional pearls for managing chronic kidney disease include paying attention to a patient’s mental health; depression occurs in roughly 25%-47% of CKD patients, and anxiety in approximately 27%, said Ms. Zuber. Depression “is believed to be the most common psychiatric disorder in patients with end stage renal disease,” and data suggest that managing depression can help improve survival in CKD patients.

“Kidney disease is the most common chronic disease in the United States and the world, and the incidence is on the rise,” said Kim Zuber, PA-C, executive director of the American Academy of Nephrology PAs and outreach chair for the National Kidney Foundation in St. Petersburg, Fla.

Kidney disease also is an expensive problem that accounts for approximately 20% of the Medicare budget in the United States, she said in a virtual presentation at the Metabolic & Endocrine Disease Summit by Global Academy for Medical Education.

“It’s important that we know how to identify it and how to slow the progression if possible, and what to do when we can no longer control the disease,” she said.

Notably, the rate of growth for kidney disease is highest among adults aged 20-45 years, said Ms. Zuber. “That is the group who will live for many years with kidney disease,” but should be in their peak years of working and earning. “That is the group we do not want to develop chronic diseases.”

“Look for kidney disease. It’s not always on the chart; it is often missed because people don’t think of it,” Ms. Zuber said. Anyone over 60 years has likely lost some kidney function. Other risk factors include minority/ethnicity, hypertension or cardiovascular disease, diabetes, and a family history of kidney disease.

Women are more likely to develop chronic kidney disease (CKD), but less likely to go on dialysis, said Ms. Zuber. “What I find fascinating is that a history of oophorectomy” increases risk. Other less obvious risk factors in a medical history that should prompt a kidney disease screening include mothers who drank during pregnancy, individuals with a history of acute kidney disease, lupus, sarcoid, amyloid, gout, or other autoimmune conditions, as well as a history of kidney stones of cancer. Kidney donors or transplant recipients are at increased risk, as are smokers, soda drinkers, and heavy salt users.

CKD is missed by many health care providers, Ms. Zuber said. For example, she cited data from more than 270,000 veterans treated at a Veterans Affairs hospital in Texas, which suggested that the likelihood of adding CKD to a patient’s diagnosis was 43.7% even if lab results confirmed CKD.
 

Find the patients

There are many formulas for defining kidney function, Ms. Zuber said. The estimation of creatinine clearance (eCrCl) and estimated glomerular filtration rate (eGFR) are among them. The most common definition is to calculate eGFR using the CKD-EPI formula. Cystatin C is more exact, but it is not standardized, so a lab in one state does not use the same formula as one in another state.

Overall, all these formulas are plus or minus 30%. “It is an estimate,” she said. Within the stages of CKD, “what we know is that, if you have a high GFR, that’s good, but patients who are losing albumin are at increased risk for CKD.” The albumin is more of a risk factor for CKD than GFR, so the GFR test used doesn’t make much difference, whereas, “if you have a lot of albumin in your urine, you are going downhill,” she said.

Normally, everyone loses kidney function with age, Ms. Zuber said. Starting at age 30, individuals lose about 1 mL/min per year in measures of GFR, however, this progression is more rapid among those with CKD, so “we need to find those people who are progressing more quickly than normal.”

The way to identify the high-risk patients is albumin, Ms. Zuber said. Health care providers need to test the urine and check albumin for high levels of albumin loss through urine, and many providers simply don’t routinely conduct urine tests for patients with other CKD risk factors such as diabetes or hypertension.

Albuminuria levels of 2,000 mg/g are the most concerning, and a urine-albumin-to-creatinine ratio (UACR) test is the most effective tool to monitor kidney function, Ms. Zuber said.

She recommends ordering a UACR test at least once a year to monitor kidney loss in all patients with hypertension, diabetes, lupus, and other risk factors including race and a history of acute kidney injury.
 

Keep them healthy

Managing patients with chronic kidney disease includes attention to several categories: hypertension, diabetes, obesity, and cardiovascular disease, and mental health, Ms. Zuber said.

“If hypertension doesn’t cause your CKD, your CKD will cause hypertension,” she said. The goal for patients with CKD is a target systolic blood pressure less than 120 mm Hg. “As kidney disease progresses, hypertension becomes harder to control,” she added. Lifestyle changes including exercise, low-fat diet, limited use of salt, weight loss if needed, and stress reduction strategies can help.

For patients with diabetes and CKD, work towards a target hemoglobin A1c of 7.0 for early CKD, and of 8% for stage 4/5 or for older patients with multiple comorbidities, Ms. Zuber said.

Three-quarters of patients hospitalized with COVID-19 were still experiencing at least one symptom of the infection 6 months after being discharged, according to a follow-up study involving 1,733 patients.

“Patients with COVID-19 had symptoms of fatigue or muscle weakness, sleep difficulties, and anxiety or depression,” and those with “more severe illness during their hospital stay had increasingly impaired pulmonary diffusion capacities and abnormal chest imaging manifestations,” Chaolin Huang, MD, of Jin Yin-tan Hospital in Wuhan, China, and associates wrote in the Lancet.

Fatigue or muscle weakness, reported by 63% of patients, was the most common symptom, followed by sleep difficulties, hair loss, and smell disorder. Altogether, 76% of those examined 6 months after discharge from Jin Yin-tan hospital – the first designated for patients with COVID-19 in Wuhan – reported at least one symptom, they said.

Symptoms were more common in women than men: 81% vs. 73% had at least one symptom, and 66% vs. 59% had fatigue or muscle weakness. Women were also more likely than men to report anxiety or depression at follow-up: 28% vs. 18% (23% overall), the investigators said.

Patients with the most severe COVID-19 were 2.4 times as likely to report any symptom later, compared with those who had the least severe levels of infection. Among the 349 participants who completed a lung function test at follow-up, lung diffusion impairment was seen in 56% of those with the most severe illness and 22% of those with the lowest level, Dr. Huang and associates reported.

In a different subset of 94 patients from whom plasma samples were collected, the “seropositivity and median titres of the neutralising antibodies were significantly lower than at the acute phase,” raising concern for reinfection, they said.

The results of the study, the investigators noted, “support that those with severe disease need post-discharge care. Longer follow-up studies in a larger population are necessary to understand the full spectrum of health consequences from COVID-19.”

The Food and Drug Administration has determined that data collected on the dual SGLT1/2 inhibitor sotagliflozin (Zynquista) for treating patients with type 2 diabetes in the SOLOIST and SCORED pivotal trials can help support a New Drug Application (NDA) submission, according to a statement released on Jan. 14 by Lexicon Pharmaceuticals, the company developing this drug. Lexicon concurrently said that it hopes to potentially file this NDA later in 2021.

The statement said the FDA’s decision related to an NDA for “an indication to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent visits for heart failure in adult patients with type 2 diabetes with either worsening heart failure or additional risk factors for heart failure.”

Results from SOLOIST and SCORED, first reported in November 2020 at the American Heart Association scientific sessions, showed statistically significant benefits for their respective primary endpoints.

The findings also demonstrated several novel benefits from the first advanced clinical trials of an SGLT inhibitor that blocks both the SGLT2 protein in kidneys as well as the SGLT1 protein, which resides primarily in the gastrointestinal system and is the main route for glucose out of the gut.

In both SOLOIST and SCORED, patient outcomes on sotagliflozin tracked the benefits and adverse effects previously seen with several SGLT2 inhibitors (canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin), but in addition showed several unprecedented benefits: An ability to lower hemoglobin A1c in patients with severely depressed renal function, safe initiation in patients recently hospitalized for heart failure, the first prospective data to show improvements in patients with heart failure with preserved ejection fraction, and a higher level of protection against MIs and strokes than the SGLT2 inhibitors.

The FDA’s willingness to consider data from both trials in an NDA was not a given, as the primary endpoints for both trials underwent tweaking while they were underway to compensate for an unexpectedly early end to patient enrollment and follow-up caused by changes in drug company sponsorship and challenges introduced by the COVID-19 pandemic.

In 2019, the FDA denied the NDA for sotagliflozin as a treatment for patients with type 1 diabetes, but this indication received approval in Europe.

SOLOIST and SCORED were sponsored initially by Sanofi, and more recently by Lexicon.

While the direct toll of the COVID-19 pandemic is being tallied and shared on the nightly news, the indirect effects will undoubtedly take years to fully measure.

In two papers published online Jan. 11 in the Journal of the American College of Cardiology, researchers have started the process of quantifying the impact of the pandemic on the care of patients with cardiovascular disease (CVD).

In the first study, Rishi Wadhera, MD, MPP, MPhil, and colleagues from the Beth Israel Deaconess Medical Center and Harvard Medical School in Boston examined population-level data to determine how deaths from cardiovascular causes changed in the United States in the early months of the pandemic relative to the same periods in 2019.

In a second paper, Andrew J. Einstein, MD, PhD, from Columbia University Irving Medical Center/New York–Presbyterian Hospital and colleagues looked at the pandemic’s international impact on the diagnosis of heart disease.

Using data from the National Center for Health Statistics, Dr. Wadhera and colleagues compared death rates from cardiovascular causes in the United States from March 18, 2020, to June 2, 2020, (the first wave of the pandemic) and from Jan. 1, 2020, to March 17, 2020, (the period just before the pandemic started) and compared them to the same periods in 2019. ICD codes were used to identify underlying causes of death.

Relative to 2019, they found a significant increase in deaths from ischemic heart disease nationally (1.11; 95% confidence interval, 1.04-1.18), as well as an increase in deaths caused by hypertensive disease (1.17; 95% CI, 1.09-1.26). There was no apparent increase in deaths from heart failure, cerebrovascular disease, or other diseases of the circulatory system.

When they looked just at New York City, the area hit hardest during the early part of the pandemic, the relative increases in deaths from ischemic heart disease were more pronounced.

Deaths from ischemic heart disease or hypertensive diseases jumped 139% and 164%, respectively, between March 18, 2020, and June 2, 2020.

More modest increases in deaths were seen in the remainder of New York state, New Jersey, Michigan and Illinois, while Massachusetts and Louisiana did not see a change in cardiovascular deaths.

Several studies from different parts of the world have indicated a 40%-50% drop in hospitalization for myocardial infarction in the initial months of the pandemic, said Dr. Wadhera in an interview.

“We wanted to understand where did all the heart attacks go? And we worried that patients with urgent heart conditions were not seeking the medical care they needed. I think our data suggest that this may have been the case,” reported Dr. Wadhera.  

“This very much reflects the reality of what we’re seeing on the ground,” he told this news organization. “After the initial surge ended, when hospital volumes began to return to normal, we saw patients come into the hospital who clearly had a heart attack during the surge months – and were now experiencing complications of that event – because they had initially not come into the hospital due to concerns about exposure to the virus.”

A limitation of their data, he stressed, is whether some deaths coded as CVD deaths were really deaths from undiagnosed COVID-19. “It’s possible that some portion of the increased deaths we observed really reflect the cardiovascular complications of undiagnosed COVID-19, because we know that testing was quite limited during the early first surge of cases.”

“I think that basically three factors – patients avoiding the health care system because of fear of getting COVID, health care systems being strained and overwhelmed leading to the deferral of cardiovascular care and semi-elective procedures, and the cardiovascular complications of COVID-19 itself – all probably collectively contributed to the rise in cardiovascular deaths that we observed,” said Dr. Wadhera.

In an accompanying editorial, Michael N. Young, MD, Geisel School of Medicine at Dartmouth, Lebanon, N.H., and colleagues write that these data, taken together with an earlier study showing an increase in out-of-hospital cardiac arrests at the pandemic peak in New York City, “support the notion of excess fatalities due to unattended comorbid illnesses.” That said, attribution of death in the COVID era “remains problematic.”

In the second article, Andrew Einstein, MD, PhD, and the INCAPS COVID Investigators Group took a broader approach and looked at the impact of COVID-19 on cardiac diagnostic procedures in over 100 countries.

The INCAPS (International Atomic Energy Agency Noninvasive Cardiology Protocols Study) group has for the past decade conducted numerous studies addressing the use of best practices and worldwide practice variation in CVD diagnosis.

For this effort, they sent a survey link to INCAPS participants worldwide, ultimately including 909 survey responses from 108 countries in the final analysis.

Compared with March 2019, overall procedure volume decreased 42% in March 2020 and 64% in April 2020.

The greatest decreases were seen in stress testing (78%) and transesophageal echocardiography (76%), both procedures, noted Dr. Einstein, associated with a greater risk of aerosolization.

“Whether as we reset after COVID we return to the same place in terms of the use of cardiovascular diagnostic testing remains to be seen, but it certainly poses an opportunity to improve our utilization of various modes of testing,” said Dr. Einstein.

Using regression analysis, Dr. Einstein and colleagues were able to see that sites located in low-income and lower-middle-income countries saw an additional 22% reduction in cardiac procedures and less availability of personal protective equipment (PPE) and telehealth.

Fifty-two percent of survey respondents reported significant shortages of N95 masks early in the pandemic, with fewer issues in supplies of gloves, gowns, and face shields. Lower-income countries were more likely to face significant PPE shortages and less likely to be able to implement telehealth strategies to make up for reduced in-person care. PPE shortage itself, however, was not related to lower procedural volume on multivariable regression.

“It all really begs the question of whether there is more that the world can do to help out the developing world in terms of managing the pandemic in all its facets,” said Dr. Einstein in an interview, adding he was “shocked” to learn how difficult it was for some lower-income countries to get sufficient PPE.
 

Did shutdowns go too far?

Calling this a “remarkable study,” an editorial written by Darryl P. Leong, MBBS, PhD, John W. Eikelboom, MBBS, and Salim Yusuf, MBBS, DPhil, all from McMaster University, Hamilton, Ont., suggests that perhaps health systems in some places went too far in closing down during the first wave of the pandemic, naming specifically Canada, Eastern Europe, and Saudi Arabia as examples.

“Although these measures were taken to prepare for the worst, overwhelming numbers of patients with COVID-19 did not materialize during the first wave of the pandemic in these countries. It is possible that delaying so-called nonessential services may have been unnecessary and potentially harmful, because it likely led to delays in providing care for the treatment of serious non–COVID-19 illnesses.”

Since then, more experience and more data have largely allowed hospital systems to “tackle the ebb and flow” of COVID-19 cases in ways that limit shutdowns of important health services, they said.

Given the more pronounced effect in low- and middle-income countries, they stressed the need to focus resources on ways to promote prevention and treatment that do not rely on diagnostic procedures.

“This calls for more emphasis on developing efficient systems of telehealth, especially in poorer countries or in remote settings in all countries,” Dr. Leong and colleagues conclude.

Dr. Wadhera has reported research support from the National Heart, Lung, and Blood Institute, along with fellow senior author Robert W. Yeh, MD, MBA, who has also received personal fees and grants from several companies not related to the submitted work.

While the direct toll of the COVID-19 pandemic is being tallied and shared on the nightly news, the indirect effects will undoubtedly take years to fully measure.

In two papers published online Jan. 11 in the Journal of the American College of Cardiology, researchers have started the process of quantifying the impact of the pandemic on the care of patients with cardiovascular disease (CVD).

In the first study, Rishi Wadhera, MD, MPP, MPhil, and colleagues from the Beth Israel Deaconess Medical Center and Harvard Medical School in Boston examined population-level data to determine how deaths from cardiovascular causes changed in the United States in the early months of the pandemic relative to the same periods in 2019.

In a second paper, Andrew J. Einstein, MD, PhD, from Columbia University Irving Medical Center/New York–Presbyterian Hospital and colleagues looked at the pandemic’s international impact on the diagnosis of heart disease.

Using data from the National Center for Health Statistics, Dr. Wadhera and colleagues compared death rates from cardiovascular causes in the United States from March 18, 2020, to June 2, 2020, (the first wave of the pandemic) and from Jan. 1, 2020, to March 17, 2020, (the period just before the pandemic started) and compared them to the same periods in 2019. ICD codes were used to identify underlying causes of death.

Relative to 2019, they found a significant increase in deaths from ischemic heart disease nationally (1.11; 95% confidence interval, 1.04-1.18), as well as an increase in deaths caused by hypertensive disease (1.17; 95% CI, 1.09-1.26). There was no apparent increase in deaths from heart failure, cerebrovascular disease, or other diseases of the circulatory system.

When they looked just at New York City, the area hit hardest during the early part of the pandemic, the relative increases in deaths from ischemic heart disease were more pronounced.

Deaths from ischemic heart disease or hypertensive diseases jumped 139% and 164%, respectively, between March 18, 2020, and June 2, 2020.

More modest increases in deaths were seen in the remainder of New York state, New Jersey, Michigan and Illinois, while Massachusetts and Louisiana did not see a change in cardiovascular deaths.

Several studies from different parts of the world have indicated a 40%-50% drop in hospitalization for myocardial infarction in the initial months of the pandemic, said Dr. Wadhera in an interview.

“We wanted to understand where did all the heart attacks go? And we worried that patients with urgent heart conditions were not seeking the medical care they needed. I think our data suggest that this may have been the case,” reported Dr. Wadhera.  

“This very much reflects the reality of what we’re seeing on the ground,” he told this news organization. “After the initial surge ended, when hospital volumes began to return to normal, we saw patients come into the hospital who clearly had a heart attack during the surge months – and were now experiencing complications of that event – because they had initially not come into the hospital due to concerns about exposure to the virus.”

A limitation of their data, he stressed, is whether some deaths coded as CVD deaths were really deaths from undiagnosed COVID-19. “It’s possible that some portion of the increased deaths we observed really reflect the cardiovascular complications of undiagnosed COVID-19, because we know that testing was quite limited during the early first surge of cases.”

“I think that basically three factors – patients avoiding the health care system because of fear of getting COVID, health care systems being strained and overwhelmed leading to the deferral of cardiovascular care and semi-elective procedures, and the cardiovascular complications of COVID-19 itself – all probably collectively contributed to the rise in cardiovascular deaths that we observed,” said Dr. Wadhera.

In an accompanying editorial, Michael N. Young, MD, Geisel School of Medicine at Dartmouth, Lebanon, N.H., and colleagues write that these data, taken together with an earlier study showing an increase in out-of-hospital cardiac arrests at the pandemic peak in New York City, “support the notion of excess fatalities due to unattended comorbid illnesses.” That said, attribution of death in the COVID era “remains problematic.”

In the second article, Andrew Einstein, MD, PhD, and the INCAPS COVID Investigators Group took a broader approach and looked at the impact of COVID-19 on cardiac diagnostic procedures in over 100 countries.

The INCAPS (International Atomic Energy Agency Noninvasive Cardiology Protocols Study) group has for the past decade conducted numerous studies addressing the use of best practices and worldwide practice variation in CVD diagnosis.

For this effort, they sent a survey link to INCAPS participants worldwide, ultimately including 909 survey responses from 108 countries in the final analysis.

Compared with March 2019, overall procedure volume decreased 42% in March 2020 and 64% in April 2020.

The greatest decreases were seen in stress testing (78%) and transesophageal echocardiography (76%), both procedures, noted Dr. Einstein, associated with a greater risk of aerosolization.

“Whether as we reset after COVID we return to the same place in terms of the use of cardiovascular diagnostic testing remains to be seen, but it certainly poses an opportunity to improve our utilization of various modes of testing,” said Dr. Einstein.

Using regression analysis, Dr. Einstein and colleagues were able to see that sites located in low-income and lower-middle-income countries saw an additional 22% reduction in cardiac procedures and less availability of personal protective equipment (PPE) and telehealth.

Fifty-two percent of survey respondents reported significant shortages of N95 masks early in the pandemic, with fewer issues in supplies of gloves, gowns, and face shields. Lower-income countries were more likely to face significant PPE shortages and less likely to be able to implement telehealth strategies to make up for reduced in-person care. PPE shortage itself, however, was not related to lower procedural volume on multivariable regression.

“It all really begs the question of whether there is more that the world can do to help out the developing world in terms of managing the pandemic in all its facets,” said Dr. Einstein in an interview, adding he was “shocked” to learn how difficult it was for some lower-income countries to get sufficient PPE.
 

Did shutdowns go too far?

Calling this a “remarkable study,” an editorial written by Darryl P. Leong, MBBS, PhD, John W. Eikelboom, MBBS, and Salim Yusuf, MBBS, DPhil, all from McMaster University, Hamilton, Ont., suggests that perhaps health systems in some places went too far in closing down during the first wave of the pandemic, naming specifically Canada, Eastern Europe, and Saudi Arabia as examples.

“Although these measures were taken to prepare for the worst, overwhelming numbers of patients with COVID-19 did not materialize during the first wave of the pandemic in these countries. It is possible that delaying so-called nonessential services may have been unnecessary and potentially harmful, because it likely led to delays in providing care for the treatment of serious non–COVID-19 illnesses.”

Since then, more experience and more data have largely allowed hospital systems to “tackle the ebb and flow” of COVID-19 cases in ways that limit shutdowns of important health services, they said.

Given the more pronounced effect in low- and middle-income countries, they stressed the need to focus resources on ways to promote prevention and treatment that do not rely on diagnostic procedures.

“This calls for more emphasis on developing efficient systems of telehealth, especially in poorer countries or in remote settings in all countries,” Dr. Leong and colleagues conclude.

Dr. Wadhera has reported research support from the National Heart, Lung, and Blood Institute, along with fellow senior author Robert W. Yeh, MD, MBA, who has also received personal fees and grants from several companies not related to the submitted work. Dr. Einstein, Dr. Leong, Dr. Eikelboom, and Dr. Yusuf have reported no relevant financial relationships.
