Remdesivir effective, well-tolerated in final trial report

Drug beats placebo across multiple endpoints in COVID-19 patients

 

A final report from the multinational placebo-controlled ACTT-1 trial confirms that remdesivir is effective and well tolerated for shortening the time to recovery from COVID-19 infection.

In May 2020, remdesivir received Food and Drug Administration approval for emergency treatment of severe COVID-19 on the basis of a preliminary report on this trial. In August 2020, the FDA expanded the indication to include all hospitalized adult and pediatric patients with suspected or laboratory-confirmed COVID-19 infection irrespective of severity.

“Our findings were consistent with the findings of the preliminary report: a 10-day course of remdesivir was superior to placebo in the treatment of hospitalized patients with COVID-19,” reported a team of investigators led by John H. Beigel, MD, of the Division of Microbiology and Infectious Diseases at the National Institute of Allergy and Infectious Diseases, in the New England Journal of Medicine.

The drug’s broadened indication was not based on the ACTT-1 trial, according to Dr. Beigel. “Other data have demonstrated that remdesivir shortens recovery in patients with lower acuity. In our study, evidence of pneumonia was an enrollment requirement,” he explained in an interview.

In the newly published final ACTT-1 data, the median time to recovery was 10 days for those on active therapy versus 15 days for those randomized to placebo. With a rate ratio of 1.29 (P less than .001), this translated to a recovery that was about one third faster.

In this final report, remdesivir’s significant advantage over placebo regarding the trial’s primary endpoint was reinforced by efficacy on multiple secondary endpoints.

This benefits on multiple secondary endpoints included a 50% greater odds ratio (OR, 1.5; 95% CI, 1.2-1.9) of significant clinical improvement by day 15 after adjustment for baseline severity, a shorter initial length of hospital stay (12 vs. 17 days) and fewer days on oxygen supplementation (13 vs. 21 days) for the subgroup of patients on oxygen at enrollment.

Although the numerically lower mortality in the remdesivir arm (6.75 vs. 11.9%) did not reach statistical significance, Dr. Beigel said, “mortality was moving in the same direction as the other key endpoints.”

According to the study investigators, the types of rates of adverse events on remdesivir, which inhibits viral replication, “were generally similar in the remdesivir and placebo groups.”

In ACTT-1, 1,062 patients were randomized to remdesivir (200 mg loading dose followed by 100 mg daily for up to 9 days) or placebo. Patients were enrolled at study sites in North America, Europe, and Asia.

The data of ACTT-1 confirm a benefit from remdesivir in hospitalized COVID-19 patients with severe disease, but Dr. Beigel said he agrees with the current FDA indication that supports treatment in any hospitalized COVID-19 patient.

“We saw bigger benefits in patients with more severe infections. The benefits are not as large in patients with mild disease, but I think remdesivir should be considered in any hospitalized patient,” Dr. Beigel said.

This point of view is shared.

“I would give this drug to anyone in the hospital infected with COVID-19 assuming there was an ample supply and no need for rationing,” said Donna E. Sweet, MD, professor of internal medicine, University of Kansas, Wichita. She noted that this study has implications for hospital and hospital staff, as well as for patients.

“This type of reduction in recovery time means a reduction in potential exposures to hospital staff, a reduced need for PPE [personal protective equipment], and it will free up beds in the ICU [intensive care unit],” said Dr. Sweet, who also serves as an editorial advisory board member for Internal Medicine News.

An infectious disease specialist at the University of Minnesota also considers remdesivir to have an important role for conserving resources that deserves emphasis.

The reduction in time to recovery “is of benefit to the health system by maintaining hospital bed capacity,” said David R. Boulware, MD, professor of medicine at the University of Minnesota, Minneapolis.

According to his reading of the available data, including those from ACTT-1, the benefit appears to be greatest in those with a moderate degree of illness, which he defined as “sick enough to be hospitalized and require oxygen, yet not severely sick [and] requiring a ventilator or [extracorporeal membrane oxygenation].”

This does not preclude a benefit in those with more severe or milder disease, but patients with mild disease “are likely to recover regardless – or despite – whatever therapy they receive,” he said.

Dr. Beigel, the principal investigator of this trial, reports no potential conflicts of interest.

One measure of child COVID-19 may be trending downward

Article Type
Changed

After increasing for several weeks, the proportion of new COVID-19 cases occurring in children has dropped for the second week in a row, according to data in a new report from the American Academy of Pediatrics and the Children’s Hospital Association.

COVID-19 cases in children accounted for 12.3% of all new cases in the United States for the week ending Oct. 1, down from 15.2% the previous week. That measure had reached its highest point, 16.9%, just one week earlier (Sept. 17), the AAP and the CHA said in their weekly COVID-19 report.

The total number of COVID-19 cases in children now stands as 657,572, or 10.6% of the more than 6.2 million cases reported among Americans of all ages, based on data from the health departments of 49 states (New York does not provide ages on its website), as well as the District of Columbia, New York City, Puerto Rico, and Guam.



The child COVID-19 rate for the United States was 874 per 100,000 children as of Oct. 1, and that figure has doubled since the end of July. At the state level, the highest rates can be found in Tennessee (2,031.4 per 100,000), North Dakota (2,029.6), and South Carolina (2,002.6), with the lowest rates in Vermont (168.9), Maine (229.1), and New Hampshire (268.3), the AAP/CHA report shows.

The children of Wyoming make up the largest share, 22.4%, of any state’s COVID-19 cases, followed by North Dakota and Tennessee, both at 18.3%. New Jersey is lower than any other state at 3.9%, although New York City is a slightly lower 3.6%, the AAP and CHA said.

“The data are limited because the states differ in how they report the data, and it is unknown how many children have been infected but not tested. It is unclear how much of the increase in child cases is due to increased testing capacity,” the AAP said in an earlier statement.

CMS gives hospitals 14 weeks to start daily COVID, flu reports

Article Type
Changed

 

The federal government is giving hospitals 14 weeks to comply with daily reporting requirements for COVID-19.

Hospitals that fail to meet the requirements will be barred from participating in Medicare and Medicaid, as announced in late August in a final rule.

The Centers for Medicare & Medicaid Services will send letters on October 7 to all 6,200 hospitals that receive reimbursement from the two federal health programs informing them of how well they are doing now, said CMS Administrator Seema Verma on a press call.

Verma would not give an estimate on how many hospitals are currently not compliant. But Deborah Birx, MD, a member of the White House Coronavirus Task Force, said on the call that 86% of hospitals are currently reporting daily.

Federal officials on the call also announced that hospitals would have the option to begin reporting certain data on influenza starting October 19, but that it would become mandatory a few weeks later.

The reporting is important “to really ensure that we’re triangulating all data to understand where this epidemic is, how it’s moving through different populations, and ensuring that we’re meeting the needs of specific hospitals and communities,” Birx said.

The federal government began a new hospital reporting system in April but did not require hospitals to participate until it quietly issued guidance in mid-July informing facilities that they should no longer report to the Centers for Disease Control and Prevention (CDC).

The move perplexed many public health experts and epidemiologists, who expressed concern that asking hospitals to use a new data system during a pandemic could result in delays and lost information. The new HHS data collection site, HHS Protect, is being managed by a private contractor, not the CDC, which also raised alarms.

The final CMS rule issued in August went into effect immediately, without any chance for comment or revision. CMS said at the time that the pandemic was reason enough to skip over the normal bureaucratic process.

Hospitals were not pleased. But Verma claimed that since then CMS had been working with hospital organizations on enforcement.

“We’re going to do everything we can to facilitate reporting, including an enforcement timeline that will provide hospitals ample opportunity to come into compliance,” she said.

Hospitals that do not comply will get a notice every 3 weeks. Three weeks after the second notice, they’ll get weekly notices for a month, and a final termination notice at 14 weeks.

The Federation of American Hospitals (FAH), however, said their members were still not happy. “It is both inappropriate and frankly overkill for CMS to tie compliance with reporting to Medicare conditions of participation,” said FAH President and CEO Chip Kahn in a statement. He called the CMS proposal “sledgehammer enforcement,” and said that the continuing data request might weaken hospitals’ response to the pandemic because it would divert time and money away from patient care.

Rick Pollack, president and CEO of the American Hospital Association called the CMS rule an “overly heavy-handed approach that could jeopardize access to hospital care for all Americans.” He noted in a statement that barring hospitals from Medicare and Medicaid could harm beneficiaries and the effort to provide COVID care.

Pollack also noted that AHA has “observed errors in data processing and confusion about exactly what was being requested at the hospital, state, contractor, and federal level, and has worked diligently with the federal agencies to identify and correct those problems.”

The document that lays out U.S. Department of Health and Human Services (HHS) Protect reporting requirements were updated again on October 6 to add influenza data. The hospitals must report on total patients with laboratory-confirmed flu; previous day’s flu admissions; total ICU patients with lab-confirmed flu; total inpatients with either flu or COVID-19; and the previous day’s deaths for flu and COVID.

CDC Director Robert Redfield, MD, said on the press call that the new data will give the agency crucial hospital-level information and perhaps better estimates of the flu burden. Flu trends have been tracked using the CDC’s Influenza Hospitalization Surveillance Network (FluSurv-NET), which will not be replaced, Redfield said. But that network only tracks hospitalizations in 14 states and does not provide information in “nearly real-time,” he said.

Having the new data “will give us a true situational awareness of severe respiratory illness, provide local hospitalization trends, and help direct resources such as antiretrovirals to address potential increased impact of flu and COVID cocirculation,” Redfield said.

FDA posts COVID vaccine guidance amid White House pushback

The Food and Drug Administration on Tuesday signaled its resistance to President Donald J. Trump’s drive for an accelerated clearance of a COVID-19 vaccine, while medical and trade associations called for a thorough review of any such product before approval.

The FDA took the unusual step of posting background materials much earlier than usual for its planned Oct. 22 advisory committee meeting on potential vaccines for COVID-19. The FDA also on Tuesday afternoon released a new guidance document, expanding on a previous set of recommendations the agency released in June.

In the new guidance document, FDA officials outline what will be required for even a limited clearance, known as an emergency use authorization (EUA), for a COVID-19 vaccine.

“Data from phase 3 studies should include a median follow-up duration of at least 2 months after completion of the full vaccination regimen to help provide adequate information to assess a vaccine’s benefit-risk profile,” the FDA said in the document.

FDA staff have emphasized the higher bar that drugmakers and regulators face in considering approval of a COVID-19 vaccine.

“Vaccines are complex biological products, and an EUA for a COVID-19 vaccine may allow for rapid and widespread deployment for administration of the vaccine to millions of individuals, including healthy people,” the agency staff said in the briefing documents.

The FDA’s briefing document for the Oct. 22 meeting appears to be markedly at odds with the claim Trump made in a video Monday night, in which he told the American public that “vaccines are coming momentarily.”

Trump, who is in a tightly contested presidential race against Democratic candidate Joe Biden, has repeatedly made claims of the potential arrival of COVID vaccines that are at odds with timelines offered with guarded optimism by experts in infectious diseases.

But based on these new guidelines from the FDA, it appears that the White House may now endorse the FDA’s stance, according to a Wall Street Journal report based on “people familiar with the matter.”

The publication reports that the White House, which has yet to officially comment, “endorsed the U.S. Food and Drug Administration’s plans for assessing whether a Covid-19 vaccine should be given widely, casting aside objections to requirements that would likely mean a shot won’t be cleared until after Election Day, people familiar with the matter said.”

Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, on Monday night said during a virtual appearance at the twenty-first annual New Yorker Festival that there could be evidence as early as November or December about whether one of the vaccines now in testing will work out. He declared himself to have “cautious optimism” about potential rollout of vaccines as early as late 2020 or early 2021.

Peter Lurie, MD, MPH, who earlier served as the FDA’s associate commissioner for public health strategy and analysis, described the agency’s release of the briefing document as being a positive development.

News organizations, including the New York Times, have reported that the White House had sought to block the FDA from releasing further instructions for companies developing COVID-19 vaccines. The Associated Press on Tuesday said that a senior Trump administration official confirmed that the White House had blocked earlier FDA plans to formally publish the safety guidelines based on the 2-month data requirement, arguing that there was “no clinical or medical reason” for it.

“It is an encouraging sign that, despite opposition from the White House, the Food and Drug Administration has effectively published guidelines for emergency release of a vaccine for COVID-19 by disclosing the advice it has been providing to individual sponsors,” said Dr. Lurie, who is now executive director and president of the Center for Science in the Public Interest.

In a news release, he said the White House had sought to keep the FDA guidance under wraps “so it could maintain the public fiction that a safe and effective vaccine could be available before Election Day or even so that it could force emergency authorization of a vaccine with more limited follow-up.”

“Even the pharmaceutical industry has been clamoring for the release of these guidelines. We all want a safe and effective vaccine to end the pandemic, and we want it sooner rather than later,” Dr. Lurie said. “But we can’t afford for the Trump administration to bungle vaccine review the way they’ve bungled nearly every other aspect of its pandemic response.”

Tuesday also saw a flood of statements in support of FDA officials, including tweets from the chief executive of Pfizer, which is among the leaders in the race to develop a COVID-19 vaccine. Pfizer’s Albert Bourla, DVM, PhD, said that the FDA’s “public servants are known for their high integrity and scientific expertise and we have full faith in their ability to set appropriate standards for the approval of a COVID vaccine or treatment.”

The American Medical Association on Tuesday announced a public webinar on Wednesday where its president, Susan R. Bailey, MD, will discuss the COVID-19 vaccine review process with Peter Marks, MD, PhD, director of the Center for Biologics Evaluation and Research at the FDA. The AMA described this webinar as part of work “to restore trust in science and science-based decision-making among policymakers and the public.”

“To ensure media and the physician community are continuously informed about the federal review process for COVID-19 vaccine candidates, the AMA will host a webinar series to gain fact-based insights from the nation’s highest-ranking subject matter experts working to protect the health of the public,” the organization said in announcing the webinar.

In a statement, leaders of the Association of American Medical Colleges said that the FDA’s Vaccines and Related Biological Products Advisory Committee should evaluate any COVID-19 candidate vaccines prior to the FDA issuing an EUA.

“Full approval of a new vaccine or biologic requires demonstration of safety and effectiveness through a process that includes evaluation by the VRBPAC. Their recommendations are considered by FDA staff who ultimately have the authority to approve the new product,” said AAMC chief scientific officer Ross McKinney Jr, MD, and AAMC CEO David J. Skorton, MD, in the statement.

Thomas M. File Jr., MD, president of the Infectious Diseases Society of America, said in a statement that his association again asked the White House to “follow medical and scientific expertise in efforts to combat COVID-19.”

“It is imperative that a vaccine be approved on the basis of FDA’s quality standards and that its safety and efficacy are established before it is authorized,” Dr. File said. “A vaccine that has been approved with speed, rather than safety and efficacy, at the forefront will compound the challenges posed by this pandemic. FDA guidelines for approval that set standards the American people can trust are essential to the success of a vaccine.”

Stephen J. Ubl, chief executive of the Pharmaceutical Research and Manufacturers of America, said in a statement that his association “supports any efforts by FDA to provide clarifying guidance and we have engaged with the agency to support bringing greater transparency to the review process for COVID-19 vaccines.”

“To help address this public health crisis, our companies have also taken unprecedented steps to share vaccine clinical trial protocols and data in real time,” Mr. Ubl said. “We welcome the agency’s efforts to instill confidence in the rigorous safety of these potential vaccines.”

On Oct. 1, Michelle McMurry-Heath, MD, PhD, president and chief executive of the Biotechnology Innovation Organization, released publicly her letter urging Department of Health & Human Services Secretary Alex Azar to “publicly release all new guidance” related to a COVID-19 vaccine. Such a move would bolster public confidence in the vaccine, she said.

“We cannot allow a lack of transparency to undermine confidence in the vaccine development process. The public must have full faith in the scientific process and the rigor of FDA’s regulatory oversight if we are to end the pandemic,” she wrote in the Oct. 1 letter to Azar. “Releasing any additional guidance on granting emergency use authorization for a vaccine will go a long way in accomplishing this critical goal.”

Stroke may be the first symptom of COVID-19 in younger patients

Article Type
Changed

Stroke may be the first presenting symptom of COVID-19 in younger patients, new research suggests. Investigators carried out a meta-analysis of data, including 160 patients with COVID-19 and stroke, and found that nearly half of patients under the age of 50 were asymptomatic at the time of stroke onset.

Although younger patients had the highest risk of stroke, the highest risk of death was in patients who were older, had other chronic conditions, and had more severe COVID-19–associated respiratory symptoms.

“One of the most eye-opening findings of this study is that, for patients under 50 years old, many were totally asymptomatic when they had a stroke related to COVID-19, [which] means that, for these patients, the stroke was their first symptom of the disease,” lead author Luciano Sposato, MD, MBA, associate professor and chair in stroke research at Western University, London, Ont.

The study was published online Sept. 15 in Neurology.
 

Anecdotal reports

“In early April of 2020, we realized that COVID-19 was a highly thrombogenic disease,” said Dr. Sposato. “Almost in parallel, I started to see anecdotal reports in social media of strokes occurring in patients with COVID-19, and there were also very few case reports.”

The investigators “thought it would be a good idea to put all the data together in one paper,” he said, and began by conducting a systematic review of 10 published studies of COVID-19 and stroke (n = 125 patients), which were then pooled with 35 unpublished cases from Canada, the United States, and Iran for a total of 160 cases.

The analysis examined in-hospital mortality rates of patients with stroke and COVID-19.

In addition, the researchers conducted a second review of 150 papers, encompassing a final cohort of 3,306 COVID-19 patients with stroke of any type and 5,322 with ischemic stroke.

“Some studies reported data for only ischemic stroke, and some reported data for all strokes considered together, which resulted in a different number of patients on each meta-analysis, with a lower number of ‘any stroke’ cases,” Dr. Sposato explained. “This review looked at the number of patients who developed a stroke during admission and included thousands of patients.”

Dr. Sposato noted that the first review was conducted on single case reports and small case series “to understand the clinical characteristics of strokes in patients with COVID-19 on an individual patient level,” since “large studies, including hundreds of thousands of patients, usually do not provide the level of detail for a descriptive analysis of the clinical characteristics of a disease.”

Cluster analyses were used to “identify specific clinical phenotypes and their relationship with death.” Patients were stratified into three age groups: <50, 50-70, and >70 years (“young,” “middle aged,” and “older,” respectively). The median age was 65 years and 43% were female.
 

Mortality ‘remarkably high’

The review showed that 1.8% (95% confidence interval, 0.9%-3.7%) of patients experienced a new stroke, while 1.5% (95% CI, 0.8%-2.8%) of these experienced an ischemic stroke. “These numbers are higher than historical data for other infectious diseases – for example, 0.75% in SARS-CoV-1, 0.78% in sepsis, and 0.2% in influenza,” Dr. Sposato commented.

Moreover, “this number may be an underestimate, given that many patients die without a confirmed diagnosis and that some patients did not come to the emergency department when experiencing mild symptoms during the first months of the pandemic,” he added.

Focusing on the review of 160 patients, the researchers described in-hospital mortality for strokes of all types and for ischemic strokes alone as “remarkably high” (34.4% [95% CI, 27.2%-42.4%] and 35.7% [95% CI, 27.5%-44.8%], respectively), with most deaths occurring among ischemic stroke patients.

“This high mortality rate is higher than the [roughly] 15% to 30% reported for stroke patients without COVID-19 admitted to intensive care units,” Dr. Sposato said.
 

High-risk phenotype

Many “young” COVID-19 patients (under age 50) who had a stroke (42.9%) had no previous risk factors or comorbidities. Moreover, in almost half of these patients (48.3%), stroke was more likely to occur before the onset of any COVID-19 respiratory symptoms.

Additionally, younger patients showed the highest frequency of elevated cardiac troponin compared with middle-aged and older patients (71.4% vs. 48.4% and 27.8%, respectively). On the other hand, mortality was 67% lower in younger versus older patients (odds ratio, 0.33; 95% CI, 0.12-0.94; P = .039).

Dr. Sposato noted that the proportion of ischemic stroke patients with large-vessel occlusion was “higher than previously reported” for patients with stroke without COVID-19 (47% compared with 29%, respectively).

“We should consider COVID-19 as a new cause or risk factor for stroke. At least, patients with stroke should probably be tested for SARS-CoV-2 infection if they are young and present with a large-vessel occlusion, even in the absence of typical COVID-19 respiratory symptoms,” he suggested.

The researchers identified a “high-risk phenotype” for death for all types of stroke considered together: older age, a higher burden of comorbidities, and severe COVID-19 respiratory symptoms. Patients with all three characteristics had the highest in-hospital mortality rate (58.6%) and a threefold risk of death, compared with the rest of the cohort (OR, 3.52; 95% CI, 1.53-8.09; P = .003).

“Several potential mechanisms can explain the increased risk of stroke among COVID-19 patients, but perhaps the most important one is increased thrombogenesis secondary to an exaggerated inflammatory response,” Dr. Sposato said.
 

Not just elders

Commenting on the study, Jodi Edwards, PhD, director of the Brain and Heart Nexus Research Program at the University of Ottawa Heart Institute, said the findings are “consistent with and underscore public health messaging emphasizing that COVID-19 does not only affect the elderly and those with underlying health conditions, but can have serious and even fatal consequences at any age.”

Dr. Edwards, who was not involved with the study, emphasized that “adherence to public health recommendations is critical to begin to reduce the rising incidence in younger adults.”

Dr. Sposato acknowledged that the study was small and that there “can be problems associated with a systematic review of case reports, such as publication bias, lack of completeness of data, etc, so more research is needed.”

Dr. Sposato is supported by the Kathleen & Dr. Henry Barnett Research Chair in Stroke Research at Western University, the Edward and Alma Saraydar Neurosciences Fund of the London Health Sciences Foundation, and the Opportunities Fund of the Academic Health Sciences Centre Alternative Funding Plan of the Academic Medical Organization of Southwestern Ontario. Dr. Sposato reported speaker honoraria from Boehringer Ingelheim, Pfizer, Gore, and Bayer and research/quality improvement grants from Boehringer Ingelheim and Bayer.

Many “young” COVID-19 patients (under age 50) who had a stroke (42.9%) had no previous risk factors or comorbidities. Moreover, in almost half of these patients (48.3%), stroke was more likely to occur before the onset of any COVID-19 respiratory symptoms.

Additionally, younger patients showed the highest frequency of elevated cardiac troponin compared with middle-aged and older patients (71.4% vs. 48.4% and 27.8%, respectively). On the other hand, mortality was 67% lower in younger versus older patients (odds ratio, 0.33; 95% CI, 0.12-0.94; P = .039).

Dr. Sposato noted that the proportion of ischemic stroke patients with large-vessel occlusion was “higher than previously reported” for patients with stroke without COVID-19 (47% compared with 29%, respectively).

“We should consider COVID-19 as a new cause or risk factor for stroke. At least, patients with stroke should probably be tested for SARS-CoV-2 infection if they are young and present with a large-vessel occlusion, even in the absence of typical COVID-19 respiratory symptoms,” he suggested.

The researchers identified a “high-risk phenotype” for death for all types of stroke considered together: older age, a higher burden of comorbidities, and severe COVID-19 respiratory symptoms. Patients with all three characteristics had the highest in-hospital mortality rate (58.6%) and a threefold risk of death, compared with the rest of the cohort (OR, 3.52; 95% CI, 1.53-8.09; P = .003).

“Several potential mechanisms can explain the increased risk of stroke among COVID-19 patients, but perhaps the most important one is increased thrombogenesis secondary to an exaggerated inflammatory response,” Dr. Sposato said.
 

Not just elders

Commenting on the study, Jodi Edwards, PhD, director of the Brain and Heart Nexus Research Program at the University of Ottawa Heart Institute, said the findings are “consistent with and underscore public health messaging emphasizing that COVID-19 does not only affect the elderly and those with underlying health conditions, but can have serious and even fatal consequences at any age.”

Dr. Edwards, who was not involved with the study, emphasized that “adherence to public health recommendations is critical to begin to reduce the rising incidence in younger adults.”

Dr. Sposato acknowledged that the study was small and that there “can be problems associated with a systematic review of case reports, such as publication bias, lack of completeness of data, etc, so more research is needed.”

Dr. Sposato is supported by the Kathleen & Dr. Henry Barnett Research Chair in Stroke Research at Western University, the Edward and Alma Saraydar Neurosciences Fund of the London Health Sciences Foundation, and the Opportunities Fund of the Academic Health Sciences Centre Alternative Funding Plan of the Academic Medical Organization of Southwestern Ontario. Dr. Sposato reported speaker honoraria from Boehringer Ingelheim, Pfizer, Gore, and Bayer and research/quality improvement grants from Boehringer Ingelheim and Bayer.

Stroke may be the first presenting symptom of COVID-19 in younger patients, new research suggests. Investigators carried out a meta-analysis of data, including 160 patients with COVID-19 and stroke, and found that nearly half of patients under the age of 50 were asymptomatic at the time of stroke onset.

Although younger patients had the highest risk of stroke, the highest risk of death was in patients who were older, had other chronic conditions, and had more severe COVID-19–associated respiratory symptoms.

“One of the most eye-opening findings of this study is that, for patients under 50 years old, many were totally asymptomatic when they had a stroke related to COVID-19, [which] means that, for these patients, the stroke was their first symptom of the disease,” lead author Luciano Sposato, MD, MBA, associate professor and chair in stroke research at Western University, London, Ont.

The study was published online Sept. 15 in Neurology.
 

Anecdotal reports

“In early April of 2020, we realized that COVID-19 was a highly thrombogenic disease,” said Dr. Sposato. “Almost in parallel, I started to see anecdotal reports in social media of strokes occurring in patients with COVID-19, and there were also very few case reports.”

The investigators “thought it would be a good idea to put all the data together in one paper,” he said, and began by conducting a systematic review of 10 published studies of COVID-19 and stroke (n = 125 patients), which were then pooled with 35 unpublished cases from Canada, the United States, and Iran for a total of 160 cases.

The analysis examined in-hospital mortality rates of patients with stroke and COVID-19.

In addition, the researchers conducted a second review of 150 papers, encompassing a final cohort of 3,306 COVID-19 patients with stroke of any type and 5,322 with ischemic stroke.

“Some studies reported data for only ischemic stroke, and some reported data for all strokes considered together, which resulted in a different number of patients on each meta-analysis, with a lower number of ‘any stroke’ cases,” Dr. Sposato explained. “This review looked at the number of patients who developed a stroke during admission and included thousands of patients.”

Dr. Sposato noted that the first review was conducted on single case reports and small case series “to understand the clinical characteristics of strokes in patients with COVID-19 on an individual patient level,” since “large studies, including hundreds of thousands of patients, usually do not provide the level of detail for a descriptive analysis of the clinical characteristics of a disease.”

Cluster analyses were used to “identify specific clinical phenotypes and their relationship with death.” Patients were stratified into three age groups: <50, 50-70, and >70 years (“young,” “middle aged,” and “older,” respectively). The median age was 65 years and 43% were female.
 

Mortality ‘remarkably high’

The review showed that 1.8% (95% confidence interval, 0.9%-3.7%) of patients experienced a new stroke, while 1.5% (95% CI, 0.8%-2.8%) of these experienced an ischemic stroke. “These numbers are higher than historical data for other infectious diseases – for example, 0.75% in SARS-CoV-1, 0.78% in sepsis, and 0.2% in influenza,” Dr. Sposato commented.

Moreover, “this number may be an underestimate, given that many patients die without a confirmed diagnosis and that some patients did not come to the emergency department when experiencing mild symptoms during the first months of the pandemic,” he added.

Focusing on the review of 160 patients, the researchers described in-hospital mortality for strokes of all types and for ischemic strokes alone as “remarkably high” (34.4% [95% CI, 27.2%-42.4%] and 35.7% [95% CI, 27.5%-44.8%], respectively), with most deaths occurring among ischemic stroke patients.

“This high mortality rate is higher than the [roughly] 15% to 30% reported for stroke patients without COVID-19 admitted to intensive care units,” Dr. Sposato said.

CDC flips, acknowledges aerosol spread of COVID-19

Article Type
Changed

The Centers for Disease Control and Prevention acknowledged Oct. 5 in updated guidance that COVID-19 can sometimes be spread through the air, especially in enclosed spaces with poor ventilation, when people are more than 6 feet apart.

The information reiterates, however, that “COVID-19 is thought to spread mainly through close contact from person to person, including between people who are physically near each other (within about 6 feet). People who are infected but do not show symptoms can also spread the virus to others.”

In a statement to the media, the CDC said, “Today’s update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19–positive person left an area. In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise. Such environments and activities may contribute to the buildup of virus-carrying particles.”

“This is HUGE and been long delayed. But glad it’s now CDC official,” tweeted Eric Feigl-Ding, MD, an epidemiologist and health economist at Harvard University, Boston on Oct. 5.

The CDC announcement follows an abrupt flip-flop on information last month surrounding the aerosol spread of the virus.
 

Information deleted from website last month

On September 18, the CDC had added to its existing guidance that the virus is spread “through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks, or breathes. These particles can be inhaled into the nose, mouth, airways, and lungs and cause infection.”

The CDC then deleted that guidance on Sept. 21, saying it was a draft update released in error.

A key element of the now-deleted guidance said, “this is thought to be the main way the virus spreads.”

The information updated today reverses the now-deleted guidance and says aerosol transmission is not the main way the virus spreads.

It states that people who are within 6 feet of a person with COVID-19 or have direct contact with that person have the greatest risk of infection.

The CDC reiterated in the statement to the media today, “People can protect themselves from the virus that causes COVID-19 by staying at least 6 feet away from others, wearing a mask that covers their nose and mouth, washing their hands frequently, cleaning touched surfaces often, and staying home when sick.”

Among the journals that have published evidence on aerosol spread is Clinical Infectious Diseases, which, on July 6, published the paper, “It Is Time to Address Airborne Transmission of Coronavirus Disease 2019,” which was supported by 239 scientists.

The authors wrote, “there is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several meters, or room scale).”

Aerosols and airborne transmission “are the only way to explain super-spreader events we are seeing,” said Kimberly Prather, PhD, an atmospheric chemist at the University of California at San Diego, in an interview Oct. 5 with the Washington Post.

Dr. Prather added that, once aerosolization is acknowledged, this becomes a “fixable” problem through proper ventilation.

“Wear masks at all times indoors when others are present,” Dr. Prather said. But when inside, she said, there’s no such thing as a completely safe social distance.

Inside the flawed White House testing scheme that did not protect Trump

Article Type
Changed

 

President Donald Trump’s COVID-19 diagnosis is raising fresh questions about the White House’s strategy for testing and containing the virus for a president whose cavalier attitude about the coronavirus has persisted since it landed on American shores.

The president has said others are tested before getting close to him, appearing to hold it as an iron shield of safety. He has largely eschewed mask-wearing and social distancing in meetings, travel and public events, while holding rallies for thousands of often maskless supporters.

The Trump administration has increasingly pinned its coronavirus testing strategy for the nation on antigen tests, which do not need a traditional lab for processing and quickly return results to patients. But the results are less accurate than those of the slower PCR tests. 

An early antigen test used by the White House was woefully inaccurate. But the new antigen test the White House is using has not been independently evaluated for accuracy and reliability. Moreover, this is the kit the Trump administration is pushing out to thousands of nursing homes to test residents and staff.

Testing “isn’t a ‘get out of jail free card,’” said Dr. Alan Wells, medical director of clinical labs at the University of Pittsburgh Medical Center and creator of its test for the novel coronavirus. In general, antigen tests can miss up to half the cases that are detected by polymerase chain reaction tests, depending on the population of patients tested, he said.

The White House said the president’s diagnosis was confirmed with a PCR test but declined to say which test delivered his initial result. The White House has been using a new antigen test from Abbott Laboratories to screen its staff for COVID-19, according to two administration officials. 

The test, known as BinaxNOW, received an emergency use authorization from the Food and Drug Administration in August. It produces results in 15 minutes. Yet little is independently known about how effective it is. According to the company, the test is 97% accurate in detecting positives and 98.5% accurate in identifying those without disease. Abbott’s stated performance of its antigen test was based on examining people within 7 days of COVID symptoms appearing.

The president and first lady have both had symptoms, according to White House chief of staff Mark Meadows and the first lady’s Twitter account. The president was admitted to Walter Reed National Military Medical Center on Friday evening “out of an abundance of caution,” White House press secretary Kayleigh McEnany said in a statement.

Vice President Mike Pence is also tested daily for the virus and tested negative, spokesperson Devin O’Malley said Friday, but he did not respond to a follow-up question about which test was used.

Trump heavily promoted another Abbott rapid testing device, the ID NOW, earlier this year. But that test relies on different technology than the newer Abbott antigen test.

“I have not seen any independent evaluation of the Binax assay in the literature or in the blogs,” Wells said. “It is an unknown.”

The Department of Health and Human Services announced in August that it had signed a $760 million contract with Abbott for 150 million BinaxNOW antigen tests, which are now being distributed to nursing homes and historically black colleges and universities, as well as to governors to help inform decisions about opening and closing schools. The Big Ten football conference has also pinned playing hopes on the deployment of antigen tests following Trump’s political pressure.

However, even senior federal officials concede that a test alone isn’t likely to stop the spread of a virus that has sickened more than 7 million Americans.

“Testing does not substitute for avoiding crowded indoor spaces, washing hands, or wearing a mask when you can’t physically distance; further, a negative test today does not mean that you won’t be positive tomorrow,” Adm. Brett Giroir, the senior HHS official helming the administration’s testing effort, said in a statement at the time.

Trump could be part of a “super-spreading event,” said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Given the timing of Trump’s positive test — which he announced on Twitter early Friday – his infection “likely happened 5 or more days ago,” Osterholm said. “If so, then he was widely infectious as early as Tuesday,” the day of the first presidential debate in Cleveland.

At least seven people who attended a Rose Garden announcement last Saturday, when Trump announced his nomination of Judge Amy Coney Barrett to the Supreme Court, have since tested positive for the coronavirus. They include Trump’s former adviser Kellyanne Conway, Republican Sens. Mike Lee and Thom Tillis, and the president of the University of Notre Dame, the Rev. John Jenkins.

“Having that many infected people there all at one time, we’re still going to see transmission coming off that event for a couple days,” Osterholm said.

Osterholm notes that about 20% of infected people lead to 80% of COVID-19 cases, because “super spreaders” can infect so many people at once.

He notes that participants and audience members at Tuesday’s debate were separated by at least 6 feet. But 6 feet isn’t always enough to prevent infection, he said.

While many COVID-19 infections appear to be spread by respiratory droplets, which usually fall to the ground within 6 feet, people who are singing or speaking loudly can project virus much further. Evidence also suggests that the novel coronavirus can spread through aerosols, floating in the air like a speck of dust.

“I wonder how much virus was floating in that room that night,” Osterholm said.

Other experts say it’s too soon to say whether Trump was infected in a super-spreader event. “The president and his wife have had many exposures to many people in enclosed venues without protection,” so they could have been infected at any number of places, said Dr. William Schaffner, an infectious disease specialist at the Vanderbilt University School of Medicine. 

Although Democratic presidential candidate and former Vice President Joe Biden tested negative for the virus with a PCR test Friday, experts note that false-negative results are common in the first few days after infection. Test results over the next several days will yield more useful information.

It can take more than a week for the virus to reproduce enough to be detected, Wells said: “You are probably not detectable for 3, 5, 7, even 10 days after you’re exposed.”

In Minnesota, where Trump held an outdoor campaign rally in Duluth with hundreds of attendees Wednesday, health officials warned that a 14-day quarantine is necessary, regardless of test results.

“Anyone who was a direct contact of President Trump or known COVID-19 cases needs to quarantine and should get tested,” the Minnesota Department of Health said.

Ongoing lapses in test result reporting could hamper efforts to track and isolate sick people. As of Sept. 10, 21 states and the District of Columbia were not reporting all antigen test results, according to a KHN investigation, a lapse in reporting that officials say leaves them blind to disease spread. Since then, public health departments in Arizona, North Carolina and South Dakota all have announced plans to add antigen testing to their case reporting.

Requests for comment to the D.C. Department of Health were referred to Mayor Muriel Bowser’s office, which did not respond. District health officials told KHN in early September that the White House does not report antigen test results to them – a potential violation of federal law under the CARES Act, which says any institution performing tests to diagnose COVID-19 must report all results to local or state public health departments.

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security, said it’s not surprising that Trump tested positive, given that so many of his close associates – including his national security adviser and Secret Service officers – have also been infected by the virus.

“When you look at the number of social contacts and travel schedules, it’s not surprising,” Adalja said.

“I wonder how much virus was floating in that room that night,” Osterholm said.

Other experts say it’s too soon to say whether Trump was infected in a super-spreader event. “The president and his wife have had many exposures to many people in enclosed venues without protection,” so they could have been infected at any number of places, said Dr. William Schaffner, an infectious disease specialist at the Vanderbilt University School of Medicine. 

Although Democratic presidential candidate and former Vice President Joe Biden tested negative for the virus with a PCR test Friday, experts note that false-negative results are common in the first few days after infection. Test results over the next several days will yield more useful information.

It can take more than a week for the virus to reproduce enough to be detected, Wells said: “You are probably not detectable for 3, 5, 7, even 10 days after you’re exposed.”

In Minnesota, where Trump held an outdoor campaign rally in Duluth with hundreds of attendees Wednesday, health officials warned that a 14-day quarantine is necessary, regardless of test results.

“Anyone who was a direct contact of President Trump or known COVID-19 cases needs to quarantine and should get tested,” the Minnesota Department of Health said.

Ongoing lapses in test result reporting could hamper efforts to track and isolate sick people. As of Sept. 10, 21 states and the District of Columbia were not reporting all antigen test results, according to a KHN investigation, a lapse in reporting that officials say leaves them blind to disease spread. Since then, public health departments in Arizona, North Carolina and South Dakota all have announced plans to add antigen testing to their case reporting.

Requests for comment to the D.C. Department of Health were referred to Mayor Muriel Bowser’s office, which did not respond. District health officials told KHN in early September that the White House does not report antigen test results to them – a potential violation of federal law under the CARES Act, which says any institution performing tests to diagnose COVID-19 must report all results to local or state public health departments.

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security, said it’s not surprising that Trump tested positive, given that so many of his close associates – including his national security adviser and Secret Service officers – have also been infected by the virus.

“When you look at the number of social contacts and travel schedules, it’s not surprising,” Adalja said.

President Donald Trump’s COVID-19 diagnosis is raising fresh questions about the White House’s strategy for testing and containing the virus for a president whose cavalier attitude about the coronavirus has persisted since it landed on American shores.

The president has said others are tested before getting close to him, appearing to hold it as an iron shield of safety. He has largely eschewed mask-wearing and social distancing in meetings, travel and public events, while holding rallies for thousands of often maskless supporters.

The Trump administration has increasingly pinned its coronavirus testing strategy for the nation on antigen tests, which do not need a traditional lab for processing and quickly return results to patients. But the results are less accurate than those of the slower PCR tests. 

An early antigen test used by the White House was woefully inaccurate. But the new antigen test the White House is using has not been independently evaluated for accuracy and reliability. Moreover, this is the kit the Trump administration is pushing out to thousands of nursing homes to test residents and staff.

Testing “isn’t a ‘get out of jail free card,’” said Dr. Alan Wells, medical director of clinical labs at the University of Pittsburgh Medical Center and creator of its test for the novel coronavirus. In general, antigen tests can miss up to half the cases that are detected by polymerase chain reaction tests, depending on the population of patients tested, he said.

The White House said the president’s diagnosis was confirmed with a PCR test but declined to say which test delivered his initial result. The White House has been using a new antigen test from Abbott Laboratories to screen its staff for COVID-19, according to two administration officials. 

The test, known as BinaxNOW, received an emergency use authorization from the Food and Drug Administration in August. It produces results in 15 minutes. Yet little is independently known about how effective it is. According to the company, the test is 97% accurate in detecting positives and 98.5% accurate in identifying those without disease. Abbott’s stated performance of its antigen test was based on examining people within 7 days of COVID symptoms appearing.

The president and first lady have both had symptoms, according to White House chief of staff Mark Meadows and the first lady’s Twitter account. The president was admitted to Walter Reed National Military Medical Center on Friday evening “out of an abundance of caution,” White House press secretary Kayleigh McEnany said in a statement.

Vice President Mike Pence is also tested daily for the virus and tested negative, spokesperson Devin O’Malley said Friday, but he did not respond to a follow-up question about which test was used.

Trump heavily promoted another Abbott rapid testing device, the ID NOW, earlier this year. But that test relies on different technology than the newer Abbott antigen test.

“I have not seen any independent evaluation of the Binax assay in the literature or in the blogs,” Wells said. “It is an unknown.”

The Department of Health and Human Services announced in August that it had signed a $760 million contract with Abbott for 150 million BinaxNOW antigen tests, which are now being distributed to nursing homes and historically black colleges and universities, as well as to governors to help inform decisions about opening and closing schools. The Big Ten football conference has also pinned playing hopes on the deployment of antigen tests following Trump’s political pressure.

However, even senior federal officials concede that a test alone isn’t likely to stop the spread of a virus that has sickened more than 7 million Americans.

“Testing does not substitute for avoiding crowded indoor spaces, washing hands, or wearing a mask when you can’t physically distance; further, a negative test today does not mean that you won’t be positive tomorrow,” Adm. Brett Giroir, the senior HHS official helming the administration’s testing effort, said in a statement at the time.

Trump could be part of a “super-spreading event,” said Dr. Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.

Given the timing of Trump’s positive test — which he announced on Twitter early Friday – his infection “likely happened 5 or more days ago,” Osterholm said. “If so, then he was widely infectious as early as Tuesday,” the day of the first presidential debate in Cleveland.

At least seven people who attended a Rose Garden announcement last Saturday, when Trump announced his nomination of Judge Amy Coney Barrett to the Supreme Court, have since tested positive for the coronavirus. They include Trump’s former adviser Kellyanne Conway, Republican Sens. Mike Lee and Thom Tillis, and the president of the University of Notre Dame, the Rev. John Jenkins.

“Having that many infected people there all at one time, we’re still going to see transmission coming off that event for a couple days,” Osterholm said.

Osterholm notes that about 20% of infected people lead to 80% of COVID-19 cases, because “super spreaders” can infect so many people at once.

He notes that participants and audience members at Tuesday’s debate were separated by at least 6 feet. But 6 feet isn’t always enough to prevent infection, he said.

While many COVID-19 infections appear to be spread by respiratory droplets, which usually fall to the ground within 6 feet, people who are singing or speaking loudly can project virus much further. Evidence also suggests that the novel coronavirus can spread through aerosols, floating in the air like a speck of dust.

‘Celebration’ will be ‘short-lived’ if COVID vaccine rushed: Experts

Article Type
Changed

U.S. regulators eventually could safely approve vaccines for COVID-19 if the process is kept free of political pressure regarding time lines, study protocols, and safety standards, expert witnesses told a House panel investigating the process on Wednesday.

The career staff of the Food and Drug Administration can be counted on to appropriately weigh whether a vaccine should be cleared for use in preventing COVID-19, witnesses, including Paul A. Offit, MD, of Children’s Hospital of Philadelphia, told the House Energy and Commerce Committee’s oversight and investigations panel.

FDA staffers would object to attempts by the Trump administration to rush a vaccine to the public without proper vetting, as would veteran federal researchers, including National Institutes of Health Director Francis S. Collins, MD, PhD, and Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, Offit said.

“If COVID-19 vaccines are released before they’re ready to be released, you will hear from these people, and you will also hear from people like Dr. Francis Collins and Tony Fauci, both of whom are trusted by the American public, as well as many other academicians and researchers who wouldn’t stand for this,” he said.

“The public is already nervous about these vaccines,” said Offit, who serves on key FDA and Centers for Disease Control and Prevention committees overseeing vaccine policy. “If trusted health officials stand up and decry a premature release, the celebration by the administration will be short-lived.”

Overly optimistic estimates about a potential approval can only serve to erode the public’s trust in these crucial vaccines, said another witness, Ashish K. Jha, MD, MPH, the dean of Brown University’s School of Public Health, in Providence, Rhode Island.

“All political leaders need to stop talking about things like time lines,” Jha told the lawmakers.

President Donald Trump has several times suggested that a COVID vaccine might be approved ahead of the November 3 election, where he faces a significant challenge from his Democratic rival, former Vice President Joe Biden.

In a Tuesday night debate with Biden, Trump again raised the idea of a quick approval. “Now we’re weeks away from a vaccine,” Trump said during the debate.

Trump’s estimates, though, are not in line with those offered by most firms involved with making vaccines. The most optimistic projections have come from Pfizer Inc. The drugmaker’s chief executive, Albert Bourla, has spoken about his company possibly having data to present to the FDA as early as late October about the safety and effectiveness of a vaccine.

In a September 8 interview with the Today show, Bourla said there was a 60% chance his company would meet that goal. In response to a question, he made it clear his comments applied to a potential Pfizer application, not an approval or release of a vaccine by that time.

In response to concerns about political pressures, the FDA in June issued guidance outlining what its staff would require for approval of a COVID-19 vaccine.
 

Pushback on politics

Another witness at the Wednesday hearing, Mark McClellan, MD, PhD, a former FDA commissioner (2002 – 2004), pushed back on objections to a potential release of further guidance from the agency.

“Some recent statements from the White House have implied that FDA’s plan to release additional written guidance on its expectations for emergency use authorization of a vaccine is unnecessarily raising the bar on regulatory standards for authorization,” said McClellan in his testimony for the House panel. “That is not the case.”

Instead, further FDA guidance would be a welcome form of feedback for the firms trying to develop COVID-19 vaccines, according to McClellan, who also serves on the board of directors for Johnson & Johnson. Johnson & Johnson is among the firms that have advanced a COVID-19 vaccine candidate to phase 3 testing. In his role as a director, he serves on the board’s regulatory compliance committee.

Along with politics, recent stumbles at FDA with emergency use authorizations (EUAs) of treatments for COVID-19 have eroded the public’s confidence in the agency, Jha told the House panel. The FDA approved hydroxychloroquine, a medicine promoted by Trump for use in COVID, under an EUA in March and then revoked this clearance in June.

Jha said the FDA’s most serious misstep was its handling of convalescent plasma, which was approved through an EUA on August 23 “in a highly advertised and widely televised announcement including the president.

“The announcement solidified in the public conversation the impression that, increasingly with this administration, politics are taking over trusted, nonpartisan scientific institutions,” he said in his testimony.

Approving a COVID-19 vaccine on the limited evidence through an EUA would mark a serious departure from FDA policy, according to Jha.

“While we sometimes accept a certain level of potential harm in experimental treatments for those who are severely ill, vaccines are given to healthy people and therefore need to have a substantially higher measure of safety and effectiveness,” he explained.

Jha said the FDA has only once before used this EUA approach for a vaccine. That was for a vaccine against inhaled anthrax and was mostly distributed to high-risk soldiers and civilians in war zones.

COVID-19, in contrast, is an infection that has changed lives around the world. The virus has contributed to more than 1 million deaths, including more than 200,000 in the United States, according to the World Health Organization.

Scientists are hoping vaccines will help curb this infection, although much of the future success of vaccines depends on how widely they are used, witnesses told the House panel.
 

Debate on approaches for vaccine effectiveness

In his testimony, Jha also noted concerns about COVID-19 vaccine trials. He included a reference to a Sept. 22 opinion article titled, “These Coronavirus Trials Don›t Answer the One Question We Need to Know,” which was written by Peter Doshi, PhD, of the University of Maryland School of Pharmacy, in Baltimore, and Eric Topol, MD, a professor of molecular medicine at Scripps Research in La Jolla, Calif. Topol is also editor in chief of Medscape.

Topol and Doshi questioned why the firms Moderna, Pfizer, and AstraZeneca structured their competing trials such that “a vaccine could meet the companies’ benchmark for success if it lowered the risk of mild Covid-19, but was never shown to reduce moderate or severe forms of the disease, or the risk of hospitalization, admissions to the intensive care unit or death.”

“To say a vaccine works should mean that most people no longer run the risk of getting seriously sick,” Topol and Doshi wrote. “That’s not what these trials will determine.”

There was disagreement about this point at the hearing. U.S. Representative Morgan Griffith (R-Va.) read the section of the Doshi-Topol article quoted above and asked one witness, Offit, to weigh in.

“Do you agree with those concerns? And either way, tell me why,” Griffith asked.

“I don’t agree,” Offit responded.

“I think it’s actually much harder to prevent asymptomatic infection or mildly symptomatic infection,” he said. “If you can prevent that, you are much more likely to prevent moderate to severe disease. So I think they have it backwards.”

But other researchers also question the approaches used with the current crop of COVID-19 vaccines.

“With the current protocols, it is conceivable that a vaccine might be considered effective – and eventually approved – based primarily on its ability to prevent mild cases alone,” wrote William Haseltine, PhD, president of the nonprofit ACCESS Health International, in a September 22 opinion article in the Washington Post titled: “Beware of COVID-19 Vaccine Trials Designed to Succeed From the Start.”
In an interview with Medscape Medical News on Wednesday, Haseltine said he maintains these concerns about the tests. Earlier in his career, he was a leader in HIV research through his lab at Harvard University in Cambridge, Massachusetts, and he subsequently led a biotech company, Human Genome Sciences.

He fears consumers will not get what they might expect from the vaccines being tested.

“What people care about is if this is going to keep them out of the hospital and will it keep them alive. And that’s not even part of this protocol,” Haseltine said.

Clarence Troutman survived a 2-month hospital stay with COVID-19, then went home in early June. But he’s far from over the disease, still suffering from limited endurance, shortness of breath and hands that can be stiff and swollen.

“Before COVID, I was a 59-year-old, relatively healthy man,” said the broadband technician from Denver. “If I had to say where I’m at now, I’d say about 50% of where I was, but when I first went home, I was at 20%.”

He credits much of his progress to the “motivation and education” gleaned from a new program for post-COVID patients at the University of Colorado at Denver, Aurora, one of a small but growing number of clinics aimed at treating and studying those who have had the unpredictable coronavirus.

As the election nears, much attention is focused on daily infection numbers or the climbing death toll, but another measure matters: Patients who survive but continue to wrestle with a range of physical or mental effects, including lung damage, heart or neurologic concerns, anxiety, and depression.

“We need to think about how we’re going to provide care for patients who may be recovering for years after the virus,” said Sarah Jolley, MD, a pulmonologist with UCHealth University of Colorado Hospital and director of UCHealth’s Post-Covid Clinic, where Mr. Troutman is seen.

That need has jump-started post-COVID clinics, which bring together a range of specialists into a one-stop shop.

One of the first and largest such clinics is at Mount Sinai in New York City, but programs have also launched at the University of California,San Francisco; Stanford (Calif.) University Medical Center; and the University of Pennsylvania, Philadelphia. The Cleveland Clinic plans to open one early next year. And it’s not just academic medical centers: St. John’s Well Child and Family Center, part of a network of community clinics in south central Los Angeles, said this month it aims to test thousands of its patients who were diagnosed with COVID-19 since March for long-term effects.

The general idea is to bring together medical professionals across a broad spectrum, including physicians who specialize in lung disorders, heart issues, and brain and spinal cord problems. Mental health specialists are also involved, along with social workers and pharmacists. Many of the centers also do research studies, aiming to better understand why the virus hits certain patients so hard.

“Some of our patients, even those on a ventilator on death’s door, will come out remarkably unscathed,” said Lekshmi Santhosh, MD, an assistant professor of pulmonary critical care and a leader of the post-COVID program at UCSF, called the OPTIMAL clinic. “Others, even those who were never hospitalized, have disabling fatigue, ongoing chest pain, and shortness of breath, and there’s a whole spectrum in between.”
 

‘Staggering’ medical need

It’s too early to know how long the persistent medical effects and symptoms will linger, or to make accurate estimates on the percentage of patients affected.

Some early studies are sobering. An Austrian report released this month found that 76 of the first 86 patients studied had evidence of lung damage 6 weeks after hospital discharge, but that dropped to 48 patients at 12 weeks.

Some researchers and clinics say about 10% of U.S. COVID patients they see may have longer-running effects, said Zijian Chen, MD, medical director of the Center for Post-COVID Care at Mount Sinai, which has enrolled 400 patients so far.

If that estimate is correct – and Dr. Chen emphasized that more research is needed to make sure – it translates to patients entering the medical system in droves, often with multiple issues.

How health systems and insurers respond will be key, he said. More than 6.5 million U.S. residents have tested positive for the disease. If fewer than 10% – say 500,000 – already have long-lasting symptoms, “that number is staggering,” Dr. Chen said. “How much medical care will be needed for that?”

Though start-up costs could be a hurdle, the clinics themselves may eventually draw much-needed revenue to medical centers by attracting patients, many of whom have insurance to cover some or all of the cost of repeated visits.

Dr. Chen said the specialized centers can help lower health spending by providing more cost effective, coordinated care that avoids duplicative testing a patient might otherwise undergo.

“We’ve seen patients that when they come in, they’ve already had four MRI or CT scans and a stack of bloodwork,” he said.

The program consolidates those earlier results and determines if any additional testing is needed. Sometimes the answer to what’s causing patients’ long-lasting symptoms remains elusive. One problem for patients seeking help outside of dedicated clinics is that when there is no clear cause for their condition, they may be told the symptoms are imagined.

“I believe in the patients,” said Dr. Chen.

About half the clinic’s patients have received test results showing damage, said Dr. Chen, an endocrinologist and internal medicine physician. For those patients, the clinic can develop a treatment plan. But, frustratingly, the other half have inconclusive test results yet exhibit a range of symptoms.

“That makes it more difficult to treat,” said Dr. Chen.

Experts see parallels to a push in the past decade to establish special clinics to treat patients released from ICU wards, who may have problems related to long-term bed rest or the delirium many experience while hospitalized. Some of the current post-COVID clinics are modeled after the post-ICU clinics or are expanded versions of them.

The ICU Recovery Center at Vanderbilt University Medical Center, Nashville, Tenn., for instance, which opened in 2012, is accepting post-COVID patients.

There are about a dozen post-ICU clinics nationally, some of which are also now working with COVID patients, said James Jackson, director of long-term outcomes at the Vanderbilt center. In addition, he’s heard of at least another dozen post-COVID centers in development.

The centers generally do an initial assessment a few weeks after a patient is diagnosed or discharged from the hospital, often by video call. Check-in and repeat visits are scheduled every month or so after that.

“In an ideal world, with these post-COVID clinics, you can identify the patients and get them into rehab,” he said. “Even if the primary thing these clinics did was to say to patients: ‘This is real, it is not all in your head,’ that impact would be important.”
 

 

 

A question of feasibility

Financing is the largest obstacle, program proponents said. Many hospitals lost substantial revenue to canceled elective procedures during stay-at-home periods.

“So, it’s not a great time to be pitching a new activity that requires a start-up subsidy,” said Glenn Melnick, PhD, a professor of health economics at the University of Southern California.

At UCSF, a select group of faculty members staff the post-COVID clinics and some mental health professionals volunteer their time, said Dr. Santhosh.

Dr. Chen said he was able to recruit team members and support staff from the ranks of those whose elective patient caseload had dropped.

Dr. Jackson said unfortunately there’s not been enough research into the cost-and-clinical effectiveness of post-ICU centers.

“In the early days, there may have been questions about how much value does this add,” he noted. “Now, the question is not so much is it a good idea, but is it feasible?”

Right now, the post-COVID centers are foremost a research effort, said Len Nichols, an economist and nonresident fellow at the Urban Institute. “If these guys get good at treating long-term symptoms, that’s good for all of us. There’s not enough patients to make it a business model yet, but if they become the place to go when you get it, it could become a business model for some of the elite institutions.”

Nerve damage linked to prone positioning in COVID-19

Article Type
Changed

Among COVID-19 patients who undergo mechanical ventilation, lying in the prone position has been associated with lasting nerve damage. A new case series describes peripheral nerve injuries associated with this type of positioning and suggests ways to minimize the potential damage.

The most common sites of injury

“Physicians should remain aware of increased susceptibility to peripheral nerve damage in patients with severe COVID-19 after prone positioning, since it is surprisingly common among these patients, and should refine standard protocols accordingly to reduce that risk,” said senior author Colin Franz, MD, PhD, director of the Electrodiagnostic Laboratory, Shirley Ryan AbilityLab, Chicago.

The article was published online Sept. 4 in the British Journal of Anaesthesiology.
 

Unique type of nerve injury

Many patients who are admitted to the intensive care unit with COVID-19 undergo invasive mechanical ventilation because of acute respiratory distress syndrome (ARDS). Clinical guidelines recommend that such patients lie in the prone position 12-16 hours per day.

“Prone positioning for up to 16 hours is a therapy we use for patients with more severe forms of ARDS, and high-level evidence points to mortality benefit in patients with moderate to severe ARDS if [mechanical] ventilation occurs,” said study coauthor James McCauley Walter, MD, of the pulmonary division at Northwestern University, Chicago.

With a “significant number of COVID-19 patients flooding the ICU, we quickly started to prone a lot of them, but if you are in a specific position for multiple hours a day, coupled with the neurotoxic effects of the SARS-CoV-2 virus itself, you may be exposed to a unique type of nerve injury,” he said.

Dr. Walter said that the “incidence of asymmetric neuropathies seems out of proportion to what has been reported in non–COVID-19 settings, which is what caught our attention.”

Many of these patients are discharged to rehabilitation hospitals, and “what we noticed, which was unique about COVID-19 patients coming to our rehab hospital, was that, compared with other patients who had been critically ill with a long hospital stay, there was a significantly higher percentage of COVID-19 patients who had peripheral nerve damage,” Dr. Franz said.

The authors described 12 of these patients who were admitted between April 24 and June 30, 2020 (mean age, 60.3 years; range, 23-80 years). The sample included White, Black, and Hispanic individuals. Eleven of the 12 post–COVID-19 patients with peripheral nerve damage had experienced prone positioning during acute management.

The average number of days patients received mechanical ventilation was 33.6 (range, 12-62 days). The average number of proning sessions was 4.5 (range, 1-16) with an average of 81.2 hours (range, 16-252 hours) spent prone.
 

A major contributor

Dr. Franz suggested that prone positioning is likely not the only cause of peripheral nerve damage but “may play a big role in these patients who are vulnerable because of viral infection and the critical illness that causes damage and nerve injuries.”

“The first component of lifesaving care for the critically ill in the ICU is intravenous fluids, mechanical ventilation, steroids, and antibiotics for infection,” said Dr. Walter.

“We are trying to come up with ways to place patients in prone position in safer ways, to pay attention to pressure points and areas of injury that we have seen and try to offload them, to see if we can decrease the rate of these injuries,” he added.

The researchers’ article includes a heat map diagram as a “template for where to focus the most efforts, in terms of decreasing pressure,” Dr. Walter said.

“The nerves are accepting too much force for gravely ill COVID-19 patients to handle, so we suggest using the template to determine where extra padding might be needed, or a protocol that might include changes in positioning,” he added.

Dr. Franz described the interventions used for COVID-19 patients with prone positioning–related peripheral nerve damage. “The first step is trying to address the problems one by one, either trying to solve them through exercise or teaching new skills, new ways to compensate, beginning with basic activities, such as getting out of bed and self-care,” he said.

Long-term recovery of nerve injuries depends on how severe the injuries are. Some nerves can slowly regenerate – possibly at the rate of 1 inch per month – which can be a long process, taking between a year and 18 months.

Dr. Franz said that therapies for this condition are “extrapolated from clinical trial work” on promoting nerve regeneration after surgery using electrical stimulation to enable nerves to regrow at a faster rate.

“Regeneration is not only slow, but it may not happen completely, leaving the patient with permanent nerve damage – in fact, based on our experience and what has been reported, the percentage of patients with full recovery is only 10%,” he said.

The most common symptomatic complaint other than lack of movement or feeling is neuropathic pain, “which may require medication to take the edge off the pain,” Dr. Franz added.
 

Irreversible damage?

Commenting on the study, Tae Chung, MD, of the departments of physical medicine, rehabilitation, and neurology, Johns Hopkins University, Baltimore, said the study “provides one of the first and the largest description of peripheral nerve injury associated with prone positioning for management of ARDS from COVID-19.”

Dr. Chung, who was not involved in the research, noted that “various neurological complications from COVID-19 have been reported, and some of them may result in irreversible neurological damage or delay the recovery from COVID-19 infection,” so “accurate and timely diagnosis of such neurological complications is critical for rehabilitation of the COVID-19 survivors.”

The study received no funding. Dr. Franz, Dr. Walter, study coauthors, and Dr. Chung report no relevant financial relationships.

Among COVID-19 patients who undergo mechanical ventilation, lying in the prone position has been associated with lasting nerve damage. A new case series describes peripheral nerve injuries associated with this type of positioning and suggests ways to minimize the potential damage.

The most common sites of injury

“Physicians should remain aware of increased susceptibility to peripheral nerve damage in patients with severe COVID-19 after prone positioning, since it is surprisingly common among these patients, and should refine standard protocols accordingly to reduce that risk,” said senior author Colin Franz, MD, PhD, director of the Electrodiagnostic Laboratory, Shirley Ryan AbilityLab, Chicago.

The article was published online Sept. 4 in the British Journal of Anaesthesiology.
 

Unique type of nerve injury

Many patients who are admitted to the intensive care unit with COVID-19 undergo invasive mechanical ventilation because of acute respiratory distress syndrome (ARDS). Clinical guidelines recommend that such patients lie in the prone position 12-16 hours per day.

“Prone positioning for up to 16 hours is a therapy we use for patients with more severe forms of ARDS, and high-level evidence points to mortality benefit in patients with moderate to severe ARDS if [mechanical] ventilation occurs,” said study coauthor James McCauley Walter, MD, of the pulmonary division at Northwestern University, Chicago.

With a “significant number of COVID-19 patients flooding the ICU, we quickly started to prone a lot of them, but if you are in a specific position for multiple hours a day, coupled with the neurotoxic effects of the SARS-CoV-2 virus itself, you may be exposed to a unique type of nerve injury,” he said.

Dr. Walter said that the “incidence of asymmetric neuropathies seems out of proportion to what has been reported in non–COVID-19 settings, which is what caught our attention.”

Many of these patients are discharged to rehabilitation hospitals, and “what we noticed, which was unique about COVID-19 patients coming to our rehab hospital, was that, compared with other patients who had been critically ill with a long hospital stay, there was a significantly higher percentage of COVID-19 patients who had peripheral nerve damage,” Dr. Franz said.

The authors described 12 of these patients who were admitted between April 24 and June 30, 2020 (mean age, 60.3 years; range, 23-80 years). The sample included White, Black, and Hispanic individuals. Eleven of the 12 post–COVID-19 patients with peripheral nerve damage had experienced prone positioning during acute management.

The average number of days patients received mechanical ventilation was 33.6 (range, 12-62 days). The average number of proning sessions was 4.5 (range, 1-16) with an average of 81.2 hours (range, 16-252 hours) spent prone.
 

A major contributor

Dr. Franz suggested that prone positioning is likely not the only cause of peripheral nerve damage but “may play a big role in these patients who are vulnerable because of viral infection and the critical illness that causes damage and nerve injuries.”

“The first component of lifesaving care for the critically ill in the ICU is intravenous fluids, mechanical ventilation, steroids, and antibiotics for infection,” said Dr. Walter.

“We are trying to come up with ways to place patients in prone position in safer ways, to pay attention to pressure points and areas of injury that we have seen and try to offload them, to see if we can decrease the rate of these injuries,” he added.

The researchers’ article includes a heat map diagram as a “template for where to focus the most efforts, in terms of decreasing pressure,” Dr. Walter said.

“The nerves are accepting too much force for gravely ill COVID-19 patients to handle, so we suggest using the template to determine where extra padding might be needed, or a protocol that might include changes in positioning,” he added.

Dr. Franz described the interventions used for COVID-19 patients with prone positioning–related peripheral nerve damage. “The first step is trying to address the problems one by one, either trying to solve them through exercise or teaching new skills, new ways to compensate, beginning with basic activities, such as getting out of bed and self-care,” he said.

Long-term recovery of nerve injuries depends on how severe the injuries are. Some nerves can slowly regenerate – possibly at the rate of 1 inch per month – which can be a long process, taking between a year and 18 months.

Dr. Franz said that therapies for this condition are “extrapolated from clinical trial work” on promoting nerve regeneration after surgery using electrical stimulation to enable nerves to regrow at a faster rate.

“Regeneration is not only slow, but it may not happen completely, leaving the patient with permanent nerve damage – in fact, based on our experience and what has been reported, the percentage of patients with full recovery is only 10%,” he said.

The most common symptomatic complaint other than lack of movement or feeling is neuropathic pain, “which may require medication to take the edge off the pain,” Dr. Franz added.
 

Irreversible damage?

Commenting on the study, Tae Chung, MD, of the departments of physical medicine, rehabilitation, and neurology, Johns Hopkins University, Baltimore, said the study “provides one of the first and the largest description of peripheral nerve injury associated with prone positioning for management of ARDS from COVID-19.”

Dr. Chung, who was not involved in the research, noted that “various neurological complications from COVID-19 have been reported, and some of them may result in irreversible neurological damage or delay the recovery from COVID-19 infection,” so “accurate and timely diagnosis of such neurological complications is critical for rehabilitation of the COVID-19 survivors.”

The study received no funding. Dr. Franz, Dr. Walter, study coauthors, and Dr. Chung report no relevant financial relationships.
