“The obstetrical population presents a unique challenge during this pandemic, since these patients have multiple interactions with the health care system and eventually most are admitted to the hospital for delivery,” wrote Desmond Sutton, MD, and colleagues at Columbia University Irving Medical Center, New York

In a letter published in the New England Journal of Medicine, the researchers reviewed their experiences with 215 pregnant women who delivered infants during March 22–April 4, 2020, at the New York–Presbyterian Allen Hospital and Columbia University Irving Medical Center. All the women were screened for symptoms of the COVID-19 infection on admission.

Overall, four women (1.9%) had fevers or other symptoms on admission, and all of these women tested positive for the virus that causes COVID-19. The other 211 women were afebrile and asymptomatic at admission, and 210 of them were tested via nasopharyngeal swabs. A total of 29 asymptomatic women (13.7%) tested positive for COVID-19 infection.

“Thus, 29 of the 33 patients who were positive for SARS-CoV-2 at admission (87.9%) had no symptoms of COVID-19 at presentation,” Dr. Sutton and colleagues wrote.

Three of the 29 COVID-19-positive women who were asymptomatic on admission developed fevers before they were discharged from the hospital after a median stay of 2 days. Of these, two received antibiotics for presumed endomyometritis and one patient with presumed COVID-19 infection received supportive care. In addition, one patient who was initially negative developed COVID-19 symptoms after delivery and tested positive 3 days after her initial negative test.

“Our use of universal SARS-CoV-2 testing in all pregnant patients presenting for delivery revealed that at this point in the pandemic in New York City, most of the patients who were positive for SARS-CoV-2 at delivery were asymptomatic,” Dr. Sutton and colleagues said.

Although their numbers may not be generalizable to areas with lower infection rates, they highlight the risk of COVID-19 infection in asymptomatic pregnant women, they noted.

“The potential benefits of a universal testing approach include the ability to use COVID-19 status to determine hospital isolation practices and bed assignments, inform neonatal care, and guide the use of personal protective equipment,” they concluded.
 

Continuing challenges

“What I have seen in our institute is the debate about rapid testing and the inherent problems with false negatives and false positives,” Catherine Cansino, MD, of the University of California, Davis, said in an interview. “I think there is definitely a role for universal testing, especially in areas with high prevalence,” and the New York clinicians have made a strong case.

However, the challenge remains of obtaining quick test results that would still be reliable, as many rapid tests have a false-negative rate of as much as 20%, noted Dr. Cansino, who was not involved in the New York study.

Her institution is using a test with a higher level of accuracy, “but it can take several hours or a day to get the results,” at which point the women may have gone through labor and delivery and been in contact with multiple health care workers who have used personal protective equipment accordingly if they don’t know a patient’s status.

To help guide policies, Dr. Cansino said that outcome data would be useful. “It’s hard to know how outcomes are different, and it would be good to know how transmission rates differ between symptomatic carriers and those who are asymptomatic.”

“As SARS-CoV-2, the virus responsible for COVID-19, continues to spread, pregnant women remain a unique population with required frequent health system contacts and ultimate need for delivery,” Iris Krishna, MD, of the Emory Healthcare Network in Atlanta, said in an interview. “This report in a high prevalence area demonstrated 1 out of 8 asymptomatic pregnant patients presenting for delivery were SARS-CoV-2 positive, illustrating a need for universal screening.

“As this pandemic evolves, we are learning more and more, and it is important to expand our understanding of asymptomatic transmission and the risk this may pose,” said Dr. Krishna, who was not part of the New York study.

“Key benefits to universal screening are the capability for labor and delivery units to implement best hospital practices in their care of mothers and babies, such as admitting positive patients to cohort units,” she noted. Such units would “allow for closer monitoring of mothers and babies, as well as ensuring proper use of personal protective equipment by health care teams” and also would help preserve supplies of personal protective equipment.

Dr. Krishna cited hospital testing capacity as an obvious barrier to universal screening of pregnant women, as well as factors including the need for additional protective equipment to be used during swab collection. Also, “If you get a negative result and there is a strong suspicion for COVID-19 infection, when do you retest?” she asked. “These are key questions or areas of assessment that should be considered before embarking on universal screening for pregnant women.” In addition, some patients may refuse testing out of fear of stigma or separation from their newborn.

“Implementing an ‘opt out’ approach to screening is encouraged, whereby a patient is informed that a test will be included in standard preventive screening, and they may decline the test,” Dr. Krishna said. “Routine, opt-out screening approaches have proven to be highly effective as it removes the stigma associated with testing, fosters earlier diagnosis and treatment, reduces risk of transmission, and has proven to be cost effective. Pregnant women should be reassured that universal screening is beneficial for their care and the care of their newborn baby,” she emphasized.

“Institutions should consider implementing universal screening on labor and delivery as several geographic areas are predicted to reach their peak time of COVID-19 transmission, and it is clear that asymptomatic individuals continue to play a role in its transmission,” Dr. Krishna concluded.

Dr. Sutton and associates had no financial conflicts to disclose. Neither Dr. Cansino nor Dr. Krishna had any financial conflicts to disclose. Dr. Cansino and Dr. Krishna are members of the Ob.Gyn. News Editorial Advisory Board.

The key to opening up the American economy rests on the ability to conduct mass testing, according to the Infectious Diseases Society of America (IDSA).

As policymakers weigh how to safely reopen parts of the United States, the IDSA, along with its HIV Medicine Association, issued a set of recommendations outlining the steps that would be necessary in order to begin easing physical distancing measures.

“A stepwise approach to reopening should reflect early diagnosis and enhanced surveillance for COVID-19 cases, linkage of cases to appropriate levels of care, isolation and/or quarantine, contact tracing, and data processing capabilities for state and local public health departments,” according to the recommendation document.

Some of the recommended steps include the following:
 

• Widespread testing and surveillance, including use of validated nucleic acid amplification assays and anti–SARS-CoV-2 antibody detection.
• The ability to diagnose, treat, and isolate individuals with COVID-19.
• Scaling up of health care capacity and supplies to manage recurrent episodic outbreaks.
• Maintaining a degree of physical distancing to prevent recurrent outbreaks, including use of masks, limiting gatherings, and continued distancing for susceptible adults.

“The recommendations stress that physical distancing policy changes must be based on relevant data and adequate public health resources and capacities and calls for a rolling and incremental approach to lifting these restrictions, ” Thomas File Jr., MD, IDSA president and a professor at Northeastern Ohio Universities, Rootstown, said during an April 17 press briefing.

The rolling approach “must reflect state and regional capacities for diagnosing, isolating, and treating people with the virus, tracing their contacts, protecting health care workers, and addressing the needs of populations disproportionately affected by COVID-19,” he continued.

In order to fully lift physical distancing restrictions, there would need to be effective treatments for COVID-19 and a protective vaccine that can be deployed to key at-risk populations, according to the recommendations.

During the call, Tina Q. Tan, MD, professor of pediatrics at Northwestern University, Chicago, and a member of the IDSA board of directors, said that easing social distancing requirements requires comprehensive data and that “one of the major missing data points” is the number of people who are currently infected or have been infected. She warned that easing restrictions too soon could have “disastrous consequences,” including an increase in spread of infection, hospitalization, and death rates, as well as overwhelming health care facilities.

“In order to reopen, we have to have the ability to safely, successfully, and rapidly diagnose and treat, as well as isolate, individuals with COVID-19, as well as track their contacts,” she said.

The implementation of more widespread, comprehensive testing would better enable targeting of resources, such as personal protective equipment, ICU beds, and ventilators, Dr. Tan said. “This is needed in order to ensure that, if there is an outbreak and it does occur again, the health care system and the first responders are ready for this,” she said.

Exposing contaminated N95 respirators to vaporized hydrogen peroxide (VHP) or ultraviolet (UV) light appears to eliminate the SARS-CoV-2 virus from the material and preserve the integrity of the masks fit for up to three uses, a National Institutes of Health (NIH) study shows.

Dry heat (70° C) was also found to eliminate the virus on masks but was effective for two uses instead of three.

Robert Fischer, PhD, with the National Institute of Allergy and Infectious Diseases in Hamilton, Montana, and colleagues posted the findings on a preprint server on April 15. The paper has not yet been peer reviewed.

Four methods tested

Fischer and colleagues compared four methods for decontaminating the masks, which are designed for one-time use: UV radiation (260-285 nm); 70° C dry heat; 70% ethanol spray; and VHP.

For each method, the researchers compared the rate at which SARS-CoV-2 is inactivated on N95 filter fabric to that on stainless steel.

All four methods eliminated detectable SARS-CoV-2 virus from the fabric test samples, though the time needed for decontamination varied. VHP was the quickest, requiring 10 minutes. Dry heat and UV light each required approximately 60 minutes. Ethanol required an intermediate amount of time.

To test durability over three uses, the researchers treated intact, clean masks with the same decontamination method and assessed function via quantitative fit testing.

Volunteers from the Rocky Mountain laboratory wore the masks for 2 hours to test fit and seal.

The researchers found that masks that had been decontaminated with ethanol spray did not function effectively after decontamination, and they did not recommend use of that method.

By contrast, masks decontaminated with UV and VHP could be used up to three times and function properly. Masks decontaminated with dry heat could be used two times before function declined.

“Our results indicate that N95 respirators can be decontaminated and reused in times of shortage for up to three times for UV and HPV, and up to two times for dry heat,” the authors write. “However, utmost care should be given to ensure the proper functioning of the N95 respirator after each decontamination using readily available qualitative fit testing tools and to ensure that treatments are carried out for sufficient time to achieve desired risk-reduction.”

Reassurance for clinicians

The results will reassure clinicians, many of whom are already using these decontamination methods, Ravina Kullar, PharmD, MPH, an infectious disease expert with the Infectious Diseases Society of America, told Medscape Medical News.

Kullar, who is also an adjunct faculty member at the David Geffen School of Medicine of the University of California, Los Angeles, said the most widely used methods have been UV light and VPH.

UV light has been used for years to decontaminate rooms, she said. She also said that so far, supplies of hydrogen peroxide are adequate.

A shortcoming of the study, Kullar said, is that it tested the masks for only 2 hours, whereas in clinical practice, they are being worn for much longer periods.

After the study is peer reviewed, the Centers for Disease Control and Prevention (CDC) may update its recommendations, she said.

So far, she noted, the CDC has not approved any method for decontaminating masks, “but it has said that it does not object to using these sterilizers, disinfectants, devices, and air purifiers for effectively killing this virus.”

Safe, multiple use of the masks is critical in the COVID-19 crisis, she said.

“We have to look at other mechanisms to keep these N95 respirators in use when there’s such a shortage,” she said.

Integrity of the fit was an important factor in the study.

“All health care workers have to go through a fitting to have that mask fitted appropriately. That’s why these N95s are only approved for health care professionals, not the lay public,” she said.

The study was supported by the National Institutes of Health; the Defense Advanced Research Projects Agency; the University of California, Los Angeles; the US National Science Foundation; and the US Department of Defense.

Fischer and colleagues compared four methods for decontaminating the masks, which are designed for one-time use: UV radiation (260-285 nm); 70° C dry heat; 70% ethanol spray; and VHP.

For each method, the researchers compared the rate at which SARS-CoV-2 is inactivated on N95 filter fabric to that on stainless steel.

All four methods eliminated detectable SARS-CoV-2 virus from the fabric test samples, though the time needed for decontamination varied. VHP was the quickest, requiring 10 minutes. Dry heat and UV light each required approximately 60 minutes. Ethanol required an intermediate amount of time.

To test durability over three uses, the researchers treated intact, clean masks with the same decontamination method and assessed function via quantitative fit testing.

Volunteers from the Rocky Mountain laboratory wore the masks for 2 hours to test fit and seal.

The researchers found that masks that had been decontaminated with ethanol spray did not function effectively after decontamination, and they did not recommend use of that method.

By contrast, masks decontaminated with UV and VHP could be used up to three times and function properly. Masks decontaminated with dry heat could be used two times before function declined.

“Our results indicate that N95 respirators can be decontaminated and reused in times of shortage for up to three times for UV and HPV, and up to two times for dry heat,” the authors write. “However, utmost care should be given to ensure the proper functioning of the N95 respirator after each decontamination using readily available qualitative fit testing tools and to ensure that treatments are carried out for sufficient time to achieve desired risk-reduction.”

Reassurance for clinicians

The results will reassure clinicians, many of whom are already using these decontamination methods, Ravina Kullar, PharmD, MPH, an infectious disease expert with the Infectious Diseases Society of America, told Medscape Medical News.

Kullar, who is also an adjunct faculty member at the David Geffen School of Medicine of the University of California, Los Angeles, said the most widely used methods have been UV light and VPH.

UV light has been used for years to decontaminate rooms, she said. She also said that so far, supplies of hydrogen peroxide are adequate.

A shortcoming of the study, Kullar said, is that it tested the masks for only 2 hours, whereas in clinical practice, they are being worn for much longer periods.

After the study is peer reviewed, the Centers for Disease Control and Prevention (CDC) may update its recommendations, she said.

So far, she noted, the CDC has not approved any method for decontaminating masks, “but it has said that it does not object to using these sterilizers, disinfectants, devices, and air purifiers for effectively killing this virus.”

Safe, multiple use of the masks is critical in the COVID-19 crisis, she said.

“We have to look at other mechanisms to keep these N95 respirators in use when there’s such a shortage,” she said.

Integrity of the fit was an important factor in the study.

“All health care workers have to go through a fitting to have that mask fitted appropriately. That’s why these N95s are only approved for health care professionals, not the lay public,” she said.

The study was supported by the National Institutes of Health; the Defense Advanced Research Projects Agency; the University of California, Los Angeles; the US National Science Foundation; and the US Department of Defense.

There was no hand sanitizer on the hospital’s psychiatric ward for fear patients would drink it; they slept together on futons in communal rooms and the windows were sealed shut to prevent suicide attempts — all conditions that created the perfect environment for the rapid spread of a potentially deadly virus.

This scenario may sound like a something out of a horror film, but as reported last month by the UK newspaper The Independent, it was the reality in the psychiatric ward of South Korea’s Daenam Hospital after COVID-19 struck. Eventually health officials put the ward on lockdown, but it wasn’t long before all but two of the unit’s 103 patients were positive for the virus.

To avoid a similar catastrophe, staff at an Israeli hospital have created what they describe as the “world’s first” dedicated COVID-19 unit for psychiatric inpatients.

Clinicians at Israel’s national hospital, Sheba Medical Center Tel HaShomer in Tel Aviv, believe the 16-bed unit, which officially opened on March 26, will stop psychiatric inpatients with the virus — who may have trouble with social distancing — from spreading it to others on the ward.

“Psychiatric patients are going to get sick from coronavirus just like anybody else,” Mark Weiser, MD, head of the psychiatric division at the institution told Medscape Medical News. “But we’re concerned that, on a psychiatric ward, a patient who is COVID-19 positive can also be psychotic, manic, cognitively impaired, or have poor judgment … making it difficult for that patient to keep social distancing, and very quickly you’ll have an entire ward of patients infected.

“So the basic public health issue is how to prevent a single psychiatric patient who is hospitalized and COVID-19-positive from making everybody else sick,” he added.
 

Unique Challenges, Rapid Response

Adapting an existing psychiatric ward to one exclusively used by inpatients with COVID-19 required significant planning, coordination, and modifications to ensure the well-being of patients and staff.

First, the ward’s air conditioning system was re-engineered to separate it from the hospital’s main system. A dedicated entrance for the exclusive use of infected psychiatric inpatients was also created.

In addition, two-way television cameras in patients’ rooms were installed to facilitate a constant flow of communication and enable therapeutic sessions and family visits. All of these modifications were completed in under a week.

“Under normal circumstances, we have cameras in the public areas of our wards, but in order to respect people’s privacy, we do not have cameras in their rooms.

“In this specific ward, on the other hand, we did put cameras in the rooms, so if a patient needs to be watched more closely, it could be done remotely without exposing staff to the virus. We have a person who’s watching the screens at all times, just to see what’s going on and see what patients are doing,” said Weiser.

Protective personal equipment (PPE) and clothing for staff was tailored to the unique challenges posed by the ward’s patient population.

“Of course, you need to wear clothes that are protective against the virus,” said Weiser. “But sometimes our patients can get agitated or even violent, so you’ve got protect against that as well.”

With this in mind, all personnel working on the ward must put on an extra layer of PPE as well as a tear-proof robe. The institution has also implemented a strict protocol that dictates the order in which PPE is donned and doffed.

“It’s got to be done in a very careful and very specific way,” said Weiser. “We have all of it organized with a poster that explains what should be taken off or put on, and in what order.”

For institutions considering setting up a similar unit, Weiser said close proximity to an active care hospital with the capacity to provide urgent care is key.

“We’re psychiatrists; we’re not great at treating acute respiratory problems. So patients with significant respiratory problems need a place to get appropriate care quickly,” he said.

In setting up the unit, there were still a few obstacles, Weiser noted. For instance, despite the many protective and safety measures undertaken by the institution, some of the hospital staff were concerned about their risk of contracting the virus.

To address these concerns, the hospital’s leadership brought in infectious disease experts to educate hospital personnel about the virus and transmission risk.

“They told our staff that given all the precautions we had taken, there was very little risk anyone else could become infected,” Weiser said.

Despite the many challenges, Weiser said he and his colleagues are thrilled with the dedicated ward and the positive reception it has received.

“My colleagues and the directors of psychiatric hospitals all around the country are very happy with this because now they’re not hospitalizing infected patients. They’re very happy for us to take care of this,” he said.
 

“No Easy Solutions”

Commenting on the initiative for Medscape Medical News, John M. Oldham, MD, chief of staff at Baylor College of Medicine’s Menninger Clinic in Houston, Texas, raised some questions.

“Is it really going to be the treatment unit or a quarantine unit? Because if you don’t have a comparable level of established, effective treatment for these patients, then you’re simply herding them off to a different place where they’re going to suffer both illnesses,” he cautioned.

Nevertheless, Oldham recognized that the issue of how to treat psychiatric patients who test positive for COVID-19 is complex.

“We’re still wrestling with that question here at Menninger. We have created an enclosed section of the inpatient area reserved for this possibility.

“If we have a patient who tests positive, we will immediately put that patient in one of these rooms in the quarantine section. Then we will use protective equipment for our staff to go and provide care for the patient,” he said.

However, he acknowledged that a psychiatric hospital is in no position to treat patients who develop severe illness from COVID-19.

“We’re certainly worried about it,” he said, “because how many inpatient general medical units are going to want to take a significantly symptomatic COVID-19 patient who was in the hospital for being acutely suicidal? There are no easy solutions.”

Because of their place at the interface between critical care and cardiovascular medicine, critical care cardiologists are in a good position to come up with novel approaches to adapting critical care systems to the current crisis. Health care and clinical resources have been severely strained in some places, and increasing evidence suggests that SARS-CoV-2 can cause injury to most organ systems. More than a quarter of hospitalized patients have cardiac injury, which can be a key reason for clinical deterioration.

An international group of critical care cardiologists led by Jason Katz, MD, of Duke University, Durham, N.C., offered suggestions for scalable models for critical care delivery in the context of COVID-19 in the Journal of the American College of Cardiology.

Critical care cardiology developed in response to changes in patient populations and their clinical needs. Respiratory insufficiency, heart failure, structural heart disease, and multisystem organ dysfunction became more common than patients with complicated acute MI, leading cardiologists in critical care cardiology to become more proficient in general critical care medicine, and to become leaders in forming collaborative multidisciplinary teams. The authors argued that COVID-19 is precipitating a similar need to adapt to the changing needs of patients.

“This pandemic should serve as a clarion call to our health care systems that we should continue to develop a nimble workforce that can adapt to change quickly during a crisis. We believe critical care cardiologists are well positioned to help serve society in this capacity,” the authors wrote.
 

Surge staging

They proposed four surge stages based in part on an American College of Chest Physicians–endorsed model (Chest 2014 Oct;146:e61S-74S), which regards a 25% capacity surge as minor. At the other end of the spectrum, a 200% surge is defined as a “disaster.” In minor surges (less than 25% increase), the traditional cardiac ICU (CICU) model can continue to be applied. During moderate (25%-100% increases) or major (100%-200%) surges, the critical care cardiologist should collaborate or consult within multiple health care teams. Physicians not trained in critical care can assist with care of intubated and critically ill patients under the supervision of a critical care cardiologist or under the supervision of a partnership between a non–cardiac critical care medicine provider and a cardiologist. The number of patients cared for by each team should increase in step with the size of the surge.

In disaster situations (more than 200% surge), there should be adaptive and dynamic staffing reorganization. The report included an illustration of a range of steps that can be taken, including alterations to staffing, regional care systems, resource management, and triage practices. Scoring systems such as Sequential Organ Failure Assessment may be useful for triaging, but the authors also suggest employment of validated cardiac disease–specific scores, because traditional ICU measures don’t always apply well to CICU populations.

At the hospital level, deferrals should be made for elective cardiac procedures that require CICU or postanesthesia care unit recovery periods. Semielective procedures should be considered after risk-benefit considerations when delays could lead to morbidity or mortality. Even some traditional emergency procedures may need to be reevaluated in the COVID-19 context: For example, some low-risk ST-segment elevation MI (STEMI) patients don’t require ICU care but are manageable in cardiac intermediate care beds instead. Historical triage practices should be reexamined to predict which STEMI patients will require ICU care.
 

Resource allocation

The CICU work flow will be affected as some of its beds are opened up to COVID-19 patients. Standard philosophies of concentrating intense resources will have to give way to a utilitarian approach that evaluates operations based on efficiency, equity, and justice. Physician-patient contact should be minimized using technological links when possible, and rounds might be reorganized to first examine patients without COVID-19, in order to minimize between-patient spread.

Military medicine, which is used to ramping up operations during times of crisis, has potential lessons for the current pandemic. In the face of mass casualties, military physicians often turn to the North Atlantic Treaty Organization triage system, which separates patients into four categories: immediate, requiring lifesaving intervention; delayed, requiring intervention within hours to days; minimal, where the patient is injured but ambulatory; and expectant patients who are deceased or too injured to save. Impersonal though this system may be, it may be required in the most severe scenarios when resources are scarce or absent.

The authors reported no relevant financial disclosures.

The explanation for the impressive clinical benefits of sacubitril/valsartan in women with heart failure with preserved ejection fraction in the PARAGON-HF trial – but not in the men – remains elusive, Jonathan W. Cunningham, MD, said at the joint scientific sessions of the American College of Cardiology and the World Heart Federation. The meeting was conducted online after its cancellation because of the COVID-19 pandemic.

“We’ve all been trying to unravel the explanation for the differential effects between men and women in the primary trial. I don’t know that this NT-proBNP substudy gives a clear answer because we did see similar reduction in NT-proBNP in the men and women,” said Dr. Cunningham of Brigham and Women’s Hospital, Boston.

“Unfortunately, I think we’re still looking for the underlying physiological explanation for that very interesting interaction,” he added.

The PARAGON-HF trial included 4,796 patients with heart failure with preserved ejection fraction (HFpEF) who were randomized double-blind to sacubitril/valsartan (Entresto) or valsartan on top of background guideline-directed medical therapy and followed for a median of 34 months (N Engl J Med. 2019 Oct 24;381[17]:1609-20). The sacubitril/valsartan group’s 13% relative risk reduction in the primary composite endpoint of cardiovascular death and total heart failure hospitalizations fell tantalizingly short of statistical significance (P = 0.058).

In women, however, who comprised more than half of the study population, the benefit of sacubitril/valsartan was larger: a 27% relative risk reduction compared to valsartan alone. That’s a statistically significant difference in a prespecified subgroup analysis, but according to the rules of clinical trials and statistics it must be considered hypothesis-generating and nondefinitive, since the overall trial was negative. Men randomized to sacubitril/valsartan had a modest 3% increased risk of the primary endpoint compared to men on valsartan.

Because of the enormous unmet need for effective therapy for HFpEF, and the fact that HFpEF is more common in women than men, the search is on for an explanation that would account for the striking gender difference in outcome in PARAGON-HF. At ACC 2020, Dr. Cunningham presented a secondary analysis of the trial focusing on the relationships between baseline and on-treatment N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and clinical outcomes.

Among the key findings was that the higher the baseline NT-proBNP, the greater the likelihood of the primary endpoint. Also, sacubitril/valsartan reduced NT-proBNP to a similar extent in men and women: For example, by 20% compared to valsartan in men and by 18% in women when measured 16 weeks after randomization. And reduction in NT-proBNP was associated with reduced risk of cardiovascular death and heart failure hospitalizations; indeed, 60% of participants in PARAGON-HF experienced a decrease in NT-proBNP, and they had a 23% lower event rate compared to patients whose NT-proBNP increased during the course of the study.

Another intriguing finding in the parent PARAGON-HF trial was that HFpEF patients with an LVEF of 45%-57% had a 22% lower rate of the primary endpoint than those with an LVEF of 58% or more. But as with the gender difference in clinical outcomes in response to sacubitril/valsartan, the difference in outcomes based on ejection fraction was not mediated by the drug’s impact on NT-proBNP, since sacubitril/valsartan reduced NT-proBNP to a similar degree in HFpEF patients with an LVEF above or below 57%.

The difference in outcomes by ejection fraction wasn’t entirely surprising, because those low-normal–range ejection fractions where sacubitril/valsartan had a favorable impact approach those characteristic of heart failure with reduced ejection fraction (HFrEF), and guidelines give sacubitril/valsartan a class I recommendation in patients with HFrEF on the strength of the medication’s demonstrated reduction in morbidity and mortality in the PARADIGM-HF trial.

Discussant Lee R. Goldberg, MD, predicted this analysis will have an impact on the design of future clinical trials in HFpEF, which up until now have required certain minimum NT-proBNP levels for participation.

“Maybe this is why so many of our trials in HFpEF have been unsuccessful. It’s a very heterogeneous population and perhaps NT-proBNP cutoffs are leading to a lot of mischief or heterogeneity that causes us some difficulty,” said Dr. Goldberg, professor of medicine and chief of the section of advanced heart failure and cardiac transplantation at the University of Pennsylvania, Philadelphia.

Dr. Cunningham reported having no financial conflicts regarding his study. The PARAGON-HF trial was funded by Novartis.

Simultaneously with Dr. Cunningham’s presentation at ACC 2020, the study results were published online (JACC Heart Fail. 2020 Mar 26; doi: 10.1016/j.jchf.2020.03.002.

“I do not shrink from this responsibility – I welcome it.” – John F. Kennedy, inaugural address

COVID-19 has changed our world. Social distancing is now the norm and flattening the curve is our motto. Family physicians’ place on the front line of medicine is more important now than it has ever been.

In the Pennsylvania community in which we work, the first person to don protective gear and sample patients for viral testing in a rapidly organized COVID-19 testing site was John Russell, MD, a family physician. When I asked him about his experience, Dr. Russell said: “No one became a fireman to get cats out of trees ... it was to fight fires. As doctors, this is the same idea ... this is a chance to help fight the fires in our community.”

And, of course, it is primary care providers – family physicians, internists, pediatricians, nurse practitioners, physician assistants, and nurses – who day in and day out are putting aside their own fears, while dealing with those of their family, to come to work with a sense of purpose and courage.

The military uses the term “operational tempo” to describe the speed and intensity of actions relative to the speed and intensity of unfolding events in the operational environment. Family physicians are being asked to work at an increased speed in unfamiliar terrain as our environments change by the hour. The challenge is to answer the call – and take care of ourselves – in unprecedented ways. We often use anticipatory guidance with our patients to help prepare them for the challenges they will face. So too must we anticipate the things we will need to be attentive to in the coming months in order to sustain the effort that will be required of us.

With this in mind, we would be wise to consider developing plans in three domains: physical, mental, and social.

With gyms closed and restaurants limiting their offerings to take-out, this is an opportune time to create an exercise regimen at home and experiment with healthy meal options. YouTube videos abound for workouts of every length. And of course, you can simply take a daily walk, go for a run, or take a bike ride. Similarly, good choices can be made with take-out and the foods we prepare at home.

To take care of our mental health, we need to have the discipline to take breaks, delegate when necessary, and use downtime to clear our minds. Need another option? Consider meditation. Google “best meditation apps” and take your pick.

From a social standpoint, we must be proactive about preventing emotional isolation. Technology allows us to connect with others through messaging and face-to-face video. We need to remember to regularly check in with those we care about; few things in life are as affirming as the connections with those who are close to us: ­family, coworkers, and patients.

Out of crisis comes opportunity. Should we be quarantined, we can remind ourselves that Sir Isaac Newton, while in quarantine during the bubonic plague, laid the foundation for classical physics, composed theories on light and optics, and penned his first draft of the law of gravity.¹

Life carries on amidst the ­pandemic. Even though the current focus is on the ­COVID-19 crisis, our many needs, joys, and challenges as human beings remain. Today, someone will find out she is pregnant and someone else will be diagnosed with cancer, plan a wedding, or attend the funeral of a loved one. We, as family physicians, have the training to lead with courage and empathy. We have the expertise gained through years of helping patients though diverse physical and emotional challenges.

We will continue to listen to our patients’ stories, diagnose and treat their diseases, and take steps to bring a sense of calm to the chaos around us. We need to be mindful of our own mindset, because we have a choice. As the psychologist Victor Frankl said in 1946 after being liberated from the concentration camps, “Everything can be taken from a man but one thing: the last of the human freedoms – to choose one’s attitude in any given set of circumstances, to choose one’s own way.”²

It is becoming increasingly clear that obesity is one of the biggest risk factors for severe COVID-19 disease, particularly among younger patients.

Newly published data from New York show that, among those aged under 60 years, obesity was twice as likely to result in hospitalization for COVID-19 and also significantly increased the likelihood that a person would end up in intensive care.

“Obesity [in people younger than 60] appears to be a previously unrecognized risk factor for hospital admission and need for critical care. This has important and practical implications when nearly 40% of adults in the U.S. are obese with a body mass index [BMI] of [at least] 30,” wrote Jennifer Lighter, MD, of New York University Langone Health, and colleagues in their research letter published in Clinical Infectious Diseases.

Similar findings in a preprint publication, yet to be peer reviewed, from another New York hospital show that, with the exception of older age, obesity (BMI greater than 40 kg/m²) had the strongest association with hospitalization for COVID-19, increasing the risk more than 500%.

Meanwhile, a new French study shows a high frequency of obesity among patients admitted to one ICU for COVID-19; furthermore, disease severity increased with increasing BMI. One of the authors said in an interview that many of the presenting patients were younger, with their only risk factor being obesity.

“Patients with obesity should avoid any COVID-19 contamination by enforcing all prevention measures during the current pandemic,” wrote the authors, led by Arthur Simonnet, MD, Centre Hospitalier Universitaire de Lille (France).

They also stressed that COVID-19 patients “with severe obesity should be monitored more closely.”
 

Those with obesity are young and become very sick, very quickly

François Pattou, MD, PhD, coauthor of the French article published in Obesity said in an interview that, when patients with COVID-19 began to arrive at their ICU in Lille, there were young patients who did not have any other comorbidities.

“They were just obese,” he observed, adding that they seemed “to have a very specific disease, something different” from that seen before, with patients becoming very sick, very quickly.

In their study, they examined 124 consecutive patients admitted to intensive care with COVID-19 between Feb. 25 and April 5, 2020, and compared them with a historical control group of 306 patients admitted to the ICU at the same hospital for non–COVID-19-related severe acute respiratory disease in 2019.

By April 6, 60 patients with COVID-19 had been discharged from intensive care, 18 had died, and 46 remained in the unit. The majority (73%) were male, and their median age was 60 years. Obesity and severe obesity were significantly more prevalent among the patients with COVID-19, at 47.6% and 28.2% versus 25.2% and 10.8% among historical controls (P < .001 for trend).

A key finding was that those with a BMI greater than 35 had a more than 600% increased risk of requiring mechanical ventilation (odds ratio, 7.36; P = .021), compared with those with a BMI less than 25, even after adjusting for age, diabetes, and hypertension.
 

Obesity in under 60s at least doubles risk of admission in U.S.

The studies out of New York, one of which was stratified by age, paint a similar picture.

Dr. Lighter and colleagues found that, of the 3,615 individuals who tested positive for COVID-19 in their series, 775 (21%) had a BMI of 30-34 and 595 (16%) had a BMI of at least 35. Obesity wasn’t a predictor of admission to hospital or the ICU in those over the age of 60 years, but in those younger than 60 years, it was.

Those under age 60 with a BMI of 30-34 were twice as likely to be admitted to hospital (hazard ratio, 2.0; P < .0001) and critical care (HR, 1.8; P = .006), compared with those under age 60 with a BMI less than 30. Likewise, those under age 60 with a BMI of at least 35 were 2.2 (P < .0001) and 3.6 (P < .0001) times more likely to be admitted to acute and critical care.

“Unfortunately, obesity in people [less than] 60 years is a newly identified epidemiologic risk factor which may contribute to increased morbidity rates [with COVID-19] experienced in the U.S.,” they concluded.

And in the other U.S. study, Christopher M. Petrilli, MD, of New York University, and colleagues looked at 4,103 patients with COVID-19 treated between March 1 and April 2, 2020, and followed to April 7.

Just under half of patients (48.7%) were hospitalized, of whom 22.3% required mechanical ventilation and 14.6% died or were discharged to hospice. The research was published on medRxiv, showing that, apart from age, the strongest predictors of hospitalization were BMI greater than 40 (OR, 6.2) and heart failure (OR, 4.3).

“It is notable that the chronic condition with the strongest association with critical illness was obesity, with a substantially higher odds ratio than any cardiovascular or pulmonary disease,” they noted.
 

Inflammation is a possible culprit

Dr. Pattou believes that the culprit behind the increased risk of disease severity seen with obesity in COVID-19 is inflammation, mediated by fibrin deposits in the circulation, which his colleagues have seen on autopsy, and which “block oxygen passage through the blood.”

This may help explain why mechanical ventilation can be less successful in these patients. “The answer is to get rid of this inflammation,” Dr. Pattou observed.

Dr. Petrilli and colleagues also observed that obesity “is well-recognized to be a proinflammatory condition.”

And their findings showed “the importance of inflammatory markers in distinguishing future critical from noncritical illness,” they said, noting that, among these markers, early elevations in C-reactive protein and D-dimer “had the strongest association with mechanical ventilation or mortality.”

Livio Luzi, MD, of IRCCS MultiMedica, Milan, Italy, has previously written on the relationship between influenza and obesity, and discussed in an interview the potential lessons for the COVID-19 pandemic.

“Obesity is characterized by an impairment of immune response and by a low-grade chronic inflammation. Furthermore, obese subjects have an altered dynamic of pulmonary ventilation, with reduced diaphragmatic excursion,” Dr. Luzi said. These factors, alongside others, “may help to explain” the current results, and stress the importance of close monitoring of those with obesity and COVID-19.

It is becoming increasingly clear that obesity is one of the biggest risk factors for severe COVID-19 disease, particularly among younger patients.

Newly published data from New York show that, among those aged under 60 years, obesity was twice as likely to result in hospitalization for COVID-19 and also significantly increased the likelihood that a person would end up in intensive care.

“Obesity [in people younger than 60] appears to be a previously unrecognized risk factor for hospital admission and need for critical care. This has important and practical implications when nearly 40% of adults in the U.S. are obese with a body mass index [BMI] of [at least] 30,” wrote Jennifer Lighter, MD, of New York University Langone Health, and colleagues in their research letter published in Clinical Infectious Diseases.

Similar findings in a preprint publication, yet to be peer reviewed, from another New York hospital show that, with the exception of older age, obesity (BMI greater than 40 kg/m²) had the strongest association with hospitalization for COVID-19, increasing the risk more than 500%.

Meanwhile, a new French study shows a high frequency of obesity among patients admitted to one ICU for COVID-19; furthermore, disease severity increased with increasing BMI. One of the authors said in an interview that many of the presenting patients were younger, with their only risk factor being obesity.

“Patients with obesity should avoid any COVID-19 contamination by enforcing all prevention measures during the current pandemic,” wrote the authors, led by Arthur Simonnet, MD, Centre Hospitalier Universitaire de Lille (France).

They also stressed that COVID-19 patients “with severe obesity should be monitored more closely.”
 

Those with obesity are young and become very sick, very quickly

François Pattou, MD, PhD, coauthor of the French article published in Obesity said in an interview that, when patients with COVID-19 began to arrive at their ICU in Lille, there were young patients who did not have any other comorbidities.

“They were just obese,” he observed, adding that they seemed “to have a very specific disease, something different” from that seen before, with patients becoming very sick, very quickly.

In their study, they examined 124 consecutive patients admitted to intensive care with COVID-19 between Feb. 25 and April 5, 2020, and compared them with a historical control group of 306 patients admitted to the ICU at the same hospital for non–COVID-19-related severe acute respiratory disease in 2019.

By April 6, 60 patients with COVID-19 had been discharged from intensive care, 18 had died, and 46 remained in the unit. The majority (73%) were male, and their median age was 60 years. Obesity and severe obesity were significantly more prevalent among the patients with COVID-19, at 47.6% and 28.2% versus 25.2% and 10.8% among historical controls (P < .001 for trend).

A key finding was that those with a BMI greater than 35 had a more than 600% increased risk of requiring mechanical ventilation (odds ratio, 7.36; P = .021), compared with those with a BMI less than 25, even after adjusting for age, diabetes, and hypertension.
 

Obesity in under 60s at least doubles risk of admission in U.S.

The studies out of New York, one of which was stratified by age, paint a similar picture.

Dr. Lighter and colleagues found that, of the 3,615 individuals who tested positive for COVID-19 in their series, 775 (21%) had a BMI of 30-34 and 595 (16%) had a BMI of at least 35. Obesity wasn’t a predictor of admission to hospital or the ICU in those over the age of 60 years, but in those younger than 60 years, it was.

Those under age 60 with a BMI of 30-34 were twice as likely to be admitted to hospital (hazard ratio, 2.0; P < .0001) and critical care (HR, 1.8; P = .006), compared with those under age 60 with a BMI less than 30. Likewise, those under age 60 with a BMI of at least 35 were 2.2 (P < .0001) and 3.6 (P < .0001) times more likely to be admitted to acute and critical care.

“Unfortunately, obesity in people [less than] 60 years is a newly identified epidemiologic risk factor which may contribute to increased morbidity rates [with COVID-19] experienced in the U.S.,” they concluded.

And in the other U.S. study, Christopher M. Petrilli, MD, of New York University, and colleagues looked at 4,103 patients with COVID-19 treated between March 1 and April 2, 2020, and followed to April 7.

Just under half of patients (48.7%) were hospitalized, of whom 22.3% required mechanical ventilation and 14.6% died or were discharged to hospice. The research was published on medRxiv, showing that, apart from age, the strongest predictors of hospitalization were BMI greater than 40 (OR, 6.2) and heart failure (OR, 4.3).

“It is notable that the chronic condition with the strongest association with critical illness was obesity, with a substantially higher odds ratio than any cardiovascular or pulmonary disease,” they noted.
 

Inflammation is a possible culprit

Dr. Pattou believes that the culprit behind the increased risk of disease severity seen with obesity in COVID-19 is inflammation, mediated by fibrin deposits in the circulation, which his colleagues have seen on autopsy, and which “block oxygen passage through the blood.”

This may help explain why mechanical ventilation can be less successful in these patients. “The answer is to get rid of this inflammation,” Dr. Pattou observed.

Dr. Petrilli and colleagues also observed that obesity “is well-recognized to be a proinflammatory condition.”

And their findings showed “the importance of inflammatory markers in distinguishing future critical from noncritical illness,” they said, noting that, among these markers, early elevations in C-reactive protein and D-dimer “had the strongest association with mechanical ventilation or mortality.”

COVID-19 has prompted many changes in pediatric health care. They say necessity is the mother of invention. Sometimes, necessity is the motivator for the long-past-due adoption of a previous invention, such as telemedicine for minor illnesses. And sometimes necessity reminds us about what is really important in a world of high technology.

Unlike our nearly overwhelmed internal medicine, ED, and family physician colleagues, many pediatricians are in a lull that threatens the financial viability of our practices. We are postponing annual well visits. We have fewer sick visits and hospitalizations since respiratory syncytial virus (RSV) and influenza also have been reduced by social distancing. Parents are avoiding the risk of contagion in the waiting room and not bringing their children in for minor complaints. There is more telemedicine – a welcome change in financing and practice whose time has come, but was being delayed by lack of insurance coverage.

Technology has allowed clinicians to respond to the pandemic in ways that would not have been possible a few years ago. Online tools, such as subscription email lists, webinars, and electronic medical news services, provide updates when the information changes weekly on the virus’s contagiousness, asymptomatic and presymptomatic transmission, prevalence, the effectiveness of masks, and experimental treatment options. These changes have been so fast that many journal articles based on data from China were obsolete and contradicted before they appeared in print.

However, technology only helped us to more effectively do what we needed to do in the first place – come together in a world of physical distancing and work toward common goals. In many hospitals, pediatric wards were emptied by reduced RSV admissions and postponed elective surgeries. These units have been converted to accept adult patients up to age 30 or 40 years. Our med-peds colleagues quickly created webinars and online resource packages on topics pediatric hospitalists might need to care for that population. There were refresher courses on ventilator management and reminders that community pediatric hospitalists, who in the winter might have one-third of their admissions with RSV, have more experience managing viral pneumonia than the internists.

Ward teams were created with a pediatric attending and an internal medicine resident. The resident’s familiarity with the names of blood pressure medicines complemented the attending’s years of clinical judgment and bedside manner. People are stepping out of their comfort zones but initial reports from the front lines are that, with each other’s support, we’ve got this.

Mistakes in telemedicine are being made, shared, and learned from. Emergency physicians are collecting anecdotes of situations when things were missed or treatment delayed. Surgeons report seeing increased numbers of cases in which the diagnosis of appendicitis was delayed, which isn’t surprising when a pediatrician cannot lay hands on the belly. Perhaps any case in which a parent calls a second or third time should be seen in the flesh.

Some newborn nurseries are discharging mother and baby at 24 hours after birth and rediscovering what was learned about that practice, which became common in the 1990s. It works well for the vast majority of babies, but we need to be ready to detect the occasional jaundiced baby or the one where breastfeeding isn’t going well. The gray-haired pediatricians can recall those nuances.

Another key role is to help everyone process the frequent deaths during a pandemic. First, there are the families we care for. Children are losing grandparents with little warning. Parents may be overwhelmed with grief while ill themselves. That makes children vulnerable.

Our medical system in 2 months has moved heaven and earth – and significantly harmed the medical care and financial future of our children – trying to assure that every 80-year-old has the right to die while attached to a ventilator, even though only a small fraction of them will survive to discharge. Meanwhile, on the wards, visitation policies have people deteriorating and dying alone. I find this paradigm distressing and antithetical to my training.

Medicine and nursing both have long histories in which the practitioner recognized that there was little they could do to prevent the death. Their role was to compassionately guide the family through it. For some people, this connection is the most precious of the arts of medicine and nursing. We need to reexamine our values. We need to get creative. We need to involve palliative care experts and clergy with the same urgency with which we have automakers making ventilators.

Second, there are our colleagues. Pediatric caregivers, particularly trainees, rarely encounter deaths and can benefit from debriefing sessions, even short ones. There is comfort in having a colleague review the situation and say: “There was nothing you could have done.” Or even: “That minor omission did not alter the outcome.” Even when everything was done properly, deaths cause moral suffering that needs processing and healing. Even if you don’t have magic words to give, just being present aids in the healing. We are all in this, together.

As an Episcopal priest, Father Robert Pace of Fort Worth, TX, is used to putting others first and reaching out to help. So when the pulmonologist who helped him through his ordeal with COVID-19 asked if he would like to donate blood to help other patients, he did not hesitate.

“I said, ‘Absolutely,’” Pace, 53, recalls. He says the idea was ‘very appealing.’ ” During his ordeal with COVID-19 in March, he had spent 3 days in the hospital, isolated and on IV fluids and oxygen. He was short of breath, with a heartbeat more rapid than usual.

Now, fully recovered, his blood was a precious commodity, antibody-rich and potentially life-saving.

As researchers scramble to test drugs to fight COVID-19, others are turning to an age-old treatment. They’re collecting the blood of survivors and giving it to patients in the throes of a severe infection, a treatment known as convalescent plasma therapy.

Doctors say the treatment will probably serve as a bridge until other drugs and a vaccine become available.

Although the FDA considers the treatment investigational, in late March, it eased access to it. Patients can get it as part of a clinical trial or through an expanded access program overseen by hospitals or universities. A doctor can also request permission to use the treatment for a single patient.

“It is considered an emergent, compassionate need,” says John Burk, MD, a pulmonologist at Texas Health Harris Methodist Hospital, Fort Worth, who treated Pace. “It is a way to bring it to the bedside.” And the approval can happen quickly. Burk says he got one from the FDA just 20 minutes after requesting it for a severely ill patient.
 

How it works

The premise of how it works is “quite straightforward,” says Michael Joyner, MD, a professor of anesthesiology at the Mayo Clinic, Rochester, MN. “When someone is recovered and no longer symptomatic, you can harvest those antibodies from their blood and give them to someone else, and hopefully alter the course of their disease.” Joyner is the principal investigator for the FDA’s national Expanded Access to Convalescent Plasma for the Treatment of Patients with COVID-19, with 1,000 sites already signed on.

Convalescent therapy has been used to fight many other viruses, including Ebola, severe acute respiratory syndrome (SARS), the “bird” flu, H1N1 flu, and during the 1918 flu pandemic. Joyner says the strongest evidence for it comes from the 1950s, when it was used to treat a rodent-borne illness called Argentine hemorrhagic fever. Using convalescent plasma therapy for this infection reduced the death rate from nearly 43% before the treatment became common in the late 1950s to about 3% after it was widely used, one report found.

Data about convalescent therapy specifically for COVID-19 is limited. Chinese researchers reported on five critically ill patients, all on mechanical ventilation, treated with convalescent plasma after they had received antiviral and anti-inflammatory medicines. Three could leave the hospital after 51-55 days, and two were in stable condition in the hospital 37 days after the transfusion.

In another study of 10 severely ill patients, symptoms went away or improved in all 10 within 1 to 3 days after the transfusion. Two of the three on ventilators were weaned off and put on oxygen instead. None died.

Chinese researchers also reported three cases of patients with COVID-19 given the convalescent therapy who had a satisfactory recovery.

Researchers who reviewed the track record of convalescent therapy for other conditions recently concluded that the treatment doesn’t appear to cause severe side effects and it should be studied for COVID-19.

Although information on side effects specific to this treatment is evolving, Joyner says they are “very, very low.”

According to the FDA, allergic reactions can occur with plasma therapies. Because the treatment for COVID-19 is new, it is not known if patients might have other types of reactions.
 

Who can donate?

Blood bank officials and researchers running the convalescent plasma programs say the desire to help is widespread, and they’ve been deluged with offers to donate. But requirements are strict.

Donors must have evidence of COVID-19 infection, documented in a variety of ways, such as a diagnostic test by nasal swab or a blood test showing antibodies. And they must be symptom-free for 14 days, with test results, or 28 days without.

The treatment involves collecting plasma, not whole blood. Plasma, the liquid part of the blood, helps with clotting and supports immunity. During the collection, a donor’s blood is put through a machine that collects the plasma only and sends the red blood cells and platelets back to the donor.
 

Clinical trials

Requirements may be more stringent for donors joining a formal clinical trial rather than an expanded access program. For instance, potential donors in a randomized clinical trial underway at Stony Brook University must have higher antibody levels than required by the FDA, says study leader Elliott Bennett-Guerrero, MD, medical director of perioperative quality and patient safety and professor at the Renaissance School of Medicine.

He hopes to enroll up to 500 patients from the Long Island, NY, area. While clinical trials typically have a 50-50 split, with half of subjects getting a treatment and half a placebo, Bennett-Guerrero’s study will give 80% of patients the convalescent plasma and 20% standard plasma.

Julia Sabia Motley, 57, of Merrick, NY, is hoping to become a donor for the Stony Brook study. She and her husband, Sean Motley, 59, tested positive in late March. She has to pass one more test to join the trial. Her husband is also planning to try to donate. “I can finally do something,” Sabia Motley says. Her son is in the MD-PhD program at Stony Brook and told her about the study.
 

Many questions remain

The treatment for COVID-19 is in its infancy. Burk has given the convalescent plasma to two patients. One is now recovering at home, and the other is on a ventilator but improving, he says.

About 200 nationwide have received the therapy, Joyner says. He expects blood supplies to increase as more people are eligible to donate.

Questions remain about how effective the convalescent therapy will be. While experts know that the COVID-19 antibodies “can be helpful in fighting the virus, we don’t know how long the antibodies in the plasma would stay in place,” Bennett-Guerrero says.

Nor do doctors know who the therapy might work best for, beyond people with a severe or life-threatening illness. When it’s been used for other infections, it’s generally given in early stages once someone has symptoms, Joyner says.

Joyner says he sees the treatment as a stopgap ‘’until concentrated antibodies are available.” Several drug companies are working to retrieve antibodies from donors and make concentrated antibody drugs.

“Typically we would think convalescent plasma might be a helpful bridge until therapies that are safe and effective and can be mass-produced are available, such as a vaccine or a drug,” Bennett-Guerrero says.

Even so, he says that he doesn’t think he will have a problem attracting donors, and that he will have repeat donors eager to help.
 

More information for potential donors

Blood banks, the American Red Cross, and others involved in convalescent plasma therapy have posted information online for potential donors. People who don’t meet the qualifications for COVID-19 plasma donations are welcomed as regular blood donors if they meet those criteria

According to the FDA, a donation could potentially help save the lives of up to four COVID-19 patients.

Father Pace is already planning another visit to the blood bank. To pass the time last time, he says, he prayed for the person who would eventually get his blood.

As an Episcopal priest, Father Robert Pace of Fort Worth, TX, is used to putting others first and reaching out to help. So when the pulmonologist who helped him through his ordeal with COVID-19 asked if he would like to donate blood to help other patients, he did not hesitate.

“I said, ‘Absolutely,’” Pace, 53, recalls. He says the idea was ‘very appealing.’ ” During his ordeal with COVID-19 in March, he had spent 3 days in the hospital, isolated and on IV fluids and oxygen. He was short of breath, with a heartbeat more rapid than usual.

Now, fully recovered, his blood was a precious commodity, antibody-rich and potentially life-saving.

As researchers scramble to test drugs to fight COVID-19, others are turning to an age-old treatment. They’re collecting the blood of survivors and giving it to patients in the throes of a severe infection, a treatment known as convalescent plasma therapy.

Doctors say the treatment will probably serve as a bridge until other drugs and a vaccine become available.

Although the FDA considers the treatment investigational, in late March, it eased access to it. Patients can get it as part of a clinical trial or through an expanded access program overseen by hospitals or universities. A doctor can also request permission to use the treatment for a single patient.

“It is considered an emergent, compassionate need,” says John Burk, MD, a pulmonologist at Texas Health Harris Methodist Hospital, Fort Worth, who treated Pace. “It is a way to bring it to the bedside.” And the approval can happen quickly. Burk says he got one from the FDA just 20 minutes after requesting it for a severely ill patient.
 

How it works

The premise of how it works is “quite straightforward,” says Michael Joyner, MD, a professor of anesthesiology at the Mayo Clinic, Rochester, MN. “When someone is recovered and no longer symptomatic, you can harvest those antibodies from their blood and give them to someone else, and hopefully alter the course of their disease.” Joyner is the principal investigator for the FDA’s national Expanded Access to Convalescent Plasma for the Treatment of Patients with COVID-19, with 1,000 sites already signed on.

Convalescent therapy has been used to fight many other viruses, including Ebola, severe acute respiratory syndrome (SARS), the “bird” flu, H1N1 flu, and during the 1918 flu pandemic. Joyner says the strongest evidence for it comes from the 1950s, when it was used to treat a rodent-borne illness called Argentine hemorrhagic fever. Using convalescent plasma therapy for this infection reduced the death rate from nearly 43% before the treatment became common in the late 1950s to about 3% after it was widely used, one report found.

Data about convalescent therapy specifically for COVID-19 is limited. Chinese researchers reported on five critically ill patients, all on mechanical ventilation, treated with convalescent plasma after they had received antiviral and anti-inflammatory medicines. Three could leave the hospital after 51-55 days, and two were in stable condition in the hospital 37 days after the transfusion.

In another study of 10 severely ill patients, symptoms went away or improved in all 10 within 1 to 3 days after the transfusion. Two of the three on ventilators were weaned off and put on oxygen instead. None died.

Chinese researchers also reported three cases of patients with COVID-19 given the convalescent therapy who had a satisfactory recovery.

Researchers who reviewed the track record of convalescent therapy for other conditions recently concluded that the treatment doesn’t appear to cause severe side effects and it should be studied for COVID-19.

Although information on side effects specific to this treatment is evolving, Joyner says they are “very, very low.”

According to the FDA, allergic reactions can occur with plasma therapies. Because the treatment for COVID-19 is new, it is not known if patients might have other types of reactions.
 

Who can donate?

Blood bank officials and researchers running the convalescent plasma programs say the desire to help is widespread, and they’ve been deluged with offers to donate. But requirements are strict.

Donors must have evidence of COVID-19 infection, documented in a variety of ways, such as a diagnostic test by nasal swab or a blood test showing antibodies. And they must be symptom-free for 14 days, with test results, or 28 days without.

The treatment involves collecting plasma, not whole blood. Plasma, the liquid part of the blood, helps with clotting and supports immunity. During the collection, a donor’s blood is put through a machine that collects the plasma only and sends the red blood cells and platelets back to the donor.
 

Clinical trials

Requirements may be more stringent for donors joining a formal clinical trial rather than an expanded access program. For instance, potential donors in a randomized clinical trial underway at Stony Brook University must have higher antibody levels than required by the FDA, says study leader Elliott Bennett-Guerrero, MD, medical director of perioperative quality and patient safety and professor at the Renaissance School of Medicine.

He hopes to enroll up to 500 patients from the Long Island, NY, area. While clinical trials typically have a 50-50 split, with half of subjects getting a treatment and half a placebo, Bennett-Guerrero’s study will give 80% of patients the convalescent plasma and 20% standard plasma.

Julia Sabia Motley, 57, of Merrick, NY, is hoping to become a donor for the Stony Brook study. She and her husband, Sean Motley, 59, tested positive in late March. She has to pass one more test to join the trial. Her husband is also planning to try to donate. “I can finally do something,” Sabia Motley says. Her son is in the MD-PhD program at Stony Brook and told her about the study.
