COVID-19 Updates

The Janssen/Johnson & Johnson single-dose adenovirus vaccine provides 85% efficacy globally against severe COVID-19 illness, according to the highly anticipated interim phase 3 results announced this morning.

The efficacy against severe disease provided by the Janssen/J&J vaccine held true regardless of age, race/ethnicity, absence or presence of comorbidities, and geography. The 44,000-participant ENSEMBLE study was conducted in the United States, South America, and South Africa.

“The team is very diligently monitoring all the variants that come up, and there are literally thousands of these. We are acting in anticipation of a variant being a potential problem. The South African variant we too acted on right away. So we too are preparing that antigen for testing.

“With data today, we do see that not a single South African, after 28 days post vaccination, ended up needing to go to the hospital, no South African died who was vaccinated.

“We do see that 85%-plus protection in South African against severe disease. That is one of the most exciting results in the dataset today,” said Mathai Mammen, MD, PhD, global head of Janssen Research & Development.

The overall efficacy was 66% globally, 72% in the United States, 66% in Latin America, and 57% in South Africa against moderate to severe SARS-CoV-2 28 days post vaccination, officials from the National Institutes of Health and Janssen reported during a media briefing.

But the J&J vaccine has potential advantages over the existing two-dose Pfizer/BioNTech and Moderna mRNA vaccines because it’s single dose and has less stringent storage requirements – only regular refrigeration is needed versus a need to freeze the two-dose Pfizer/BioNTech and Moderna COVID-19 vaccines. The J&J vaccine can be refrigerated for up to 3 months at 36°-46° F (2°-8° C).

But the difference between these just-released efficacy figures and the 94%-95% efficacy provided by the existing Pfizer/BioNTech and Moderna mRNA vaccines generated many questions during the briefing.

Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said the focus should not just be on the overall numbers. “The most important thing from a public health standpoint domestically is to keep people out of the hospital and prevent them from getting severe illness,” he said. “Many in the general public might look at a number and want to know if they get symptomatic disease or not.”

“More important than preventing someone from getting some aches and a sore throat is to prevent people – particularly people who have underlying conditions and the elderly, the ones most susceptible to a severe outcome – [from getting] severe disease,” Dr. Fauci added. Prevention of severe outcomes in a high percentage of individuals “will alleviate so much of the stress, human suffering, and death.”

Dr. Fauci acknowledged that many people will naturally focus on the distinction between 72% efficacy and 94%-95% efficacy. “This could be a messaging challenge [but] you have to make sure people understand the implications.”

It is more complex, he added, than just asking people: “If you go to the door on the left, you get 94% or 95%. If you go to the door to the right, you get 72%. What door do you want to go to?”

Instead, the messaging should be that “this and the other vaccines we have are actually preventing severe disease to a very substantial degree.”
 

Company defends numbers

Janssen defended their efficacy findings, pointing out that it is not a fair comparison.

“The vaccine programs that went a couple of months ago, they ran their studies during different times, when the pandemic was less complex. There were not these variants, and there was not the same level of incidence, which puts pressure on vaccine efficacy,” said Mathai Mammen, MD, PhD, global head of research and development for Janssen.

“So the numbers cannot really be compared, and that does pose a messaging challenge,” he said. “But the reality is, if one was to run the same studies [for the Pfizer and Moderna vaccines] today you would likely see different results.”

Asked if the efficacy figures could affect vaccine hesitancy, National Institutes of Health Director Francis Collins, MD, PhD, said at the announcement that most reluctance among people to get vaccinated against SARS-CoV-2 stems from concerns about safety. “The safety record is extremely good for this vaccine, as it is for the others that have received emergency use authorization.”

Janssen/J&J plans to submit for emergency use authorization from the U.S. Food and Drug Administration next week, at which point the company plans to release more information on side effects, deaths, and patient subpopulation efficacy, and more from the ENSEMBLE trial.

Janssen is aiming to provide 1 billion doses by the end of this year.

Dramatic changes in the use of radiotherapy for cancer were seen during the first wave of the COVID-19 pandemic in England. Some radiotherapy regimens were shortened, but others were intensified, suggesting that they were being used as a replacement for surgery.

The findings come from an analysis of National Health Service data in England, which also indicated that overall there was a reduction in the amount of radiotherapy delivered.

“Radiotherapy is a very important treatment option for cancer, and our study shows that, across the English NHS, there was a rapid shift in how radiotherapy was used,” said lead author Katie Spencer, PhD, faculty of medicine and health, University of Leeds (England).

“It is impressive to see that the data closely follow the guidelines published at the start of the pandemic,” she said. For instance, for patients with breast and colorectal cancers, treatment regimens were shorter and more intensive, whereas for patients with prostate cancer, treatments were delayed to reduce exposure to COVID-19.

“In other cases, such as head and neck cancers and anal cancers, we saw that the number of radiotherapy treatments hardly changed during the first wave. This was really reassuring, as we know that it is vital that these treatments are not delayed,” Dr. Spencer added.

The study was published online in The Lancet Oncology on Jan. 22 (doi: 10.1016/S1470-2045[20]30743-9).

Researchers examined data from the National Radiotherapy Dataset on all radiotherapy delivered for cancer in the NHS in England between Feb. 4, 2019, and June 28, 2020.

On interrupted time-series analysis, the introduction of lockdown in response to the COVID-19 pandemic was associated with a significant reduction in both radiotherapy courses and attendances (P < .0001).

Overall, the team estimated that there were 3,263 fewer radiotherapy treatment courses and 119,050 fewer attendances than would have taken place had the pandemic not occurred.

The largest reduction in treatment courses was seen for prostate cancer, with a 77% reduction in April 2020 in comparison with April 2019, and in nonmelanoma skin cancer, for which there was a decrease of 72.4% over the same period.

There were, however, marked increases in the number of radiotherapy courses given for some disorders in April 2020 in comparison with April 2019. Radiotherapy for bladder cancer increased by 64.2%; for esophageal cancer, it increased by 41.2%; and for rectal cancer, it increased by 36.3%.

This likely reflects the fact that, during the pandemic, “surgical capacity dropped dramatically,” Dr. Spencer said in an interview.

“To try to mitigate the consequences of that, working with their multidisciplinary teams, doctors increased the use of radiotherapy to provide a timely alternative curative treatment and help mitigate the consequences of not having access to surgery,” she said.

“This is a cohort of patients who would otherwise have had their treatment delayed, and we know that’s detrimental, so having an alternative strategy that, in specific cases, can offer similar outcomes is fantastic,” she added.

The analysis shows the “incredible speed with which radiotherapy services within the NHS were able to adapt their treatment patterns to help protect patients with cancer whilst coping with reduced surgical capacity due to the global pandemic,” coauthor Tom Roques, MD, medical director of professional practice for clinical oncology at the Royal College of Radiologists, commented in a statement.
 

Shorter radiotherapy regimen for breast cancer

In addition to the pandemic, two other events led to changes in the way that radiotherapy was delivered in the period analyzed.

One was the publication in April 2020 of the FAST-Forward trial of radiotherapy for breast cancer. This showed that radiotherapy with 26 Gy in 5 fractions administered over 1 week following primary surgery for early breast cancer was noninferior to the standard 40 Gy delivered in 15 fractions over 3 weeks.

These results led to immediate changes in practice, and quick implementation across the NHS “massively freed up capacity in terms of the number of fractions being delivered but also really helped to keep patients safe by ensuring they were only visiting the hospital on 5 occasions instead of the standard 15,” Spencer said.

Indeed, the analysis showed that the proportion of all breast radiotherapy courses given as the ultrahypofractionated regimen of 26 Gy in five fractions increased from 0.2% in April 2019 to 60.0% in April 2020 (P < .0001), which the authors noted “contributed to the substantial reduction” in radiotherapy attendances.

The other event occurred in March 2020, when NHS England “dramatically changed commissioning” from a tariff-based system in which radiotherapy was paid for every fraction delivered to a “payment that reflects the amount of money that was spent the previous year.

“That supported radiotherapy providers to do what was necessary to continue to deliver the best possible care to patients with cancer despite COVID,” Dr. Spencer added. “We saw this in our study, with doctors shortening radiotherapy courses to keep patients safe and departments running.”

The question now is whether the changes resulting from these two events will be maintained once the COVID-19 pandemic lifts.

What will happen to radiotherapy service commissioning beyond the end of the financial year is currently “unclear,” Dr. Spencer commented.

“There’s strong clinical support for continuing to use the shorter treatment courses in breast cancer, although it’s hard to know how any change in commissioning and reduction in COVID risk will influence their use over the next year and beyond,” she said.

“The data we used in this study, that Public Health England collect, will be really valuable in helping us to assess this in future,” Dr. Spencer said.
 

Radiotherapy remains reduced

Dr. Spencer taid that, “whilst in April and May 2020 we saw that the fall in radiotherapy was in cancers where it›s safe to delay treatment, in June we could see that radiotherapy activity was not back up to where it was previously, and that was across a wider range of cancers.

“This looks likely to be because of a fall in the number of people being diagnosed with cancer,” she said.

“The pandemic continues to cause severe disruption for cancer diagnosis and some national screening programs,” she commented. “This has meant that fewer patients were diagnosed with cancer during the first wave of the pandemic, and this is likely to have led to the persistent fall in treatments we are seeing.”

By November 2020, some referral pathways were back up to the volume of patients that was seen before the pandemic, but “it’s very variable across different diagnoses.”

The fear is that the resurgence of COVID-19 over the past month has made the situation worse, which is “very worrying,” Dr. Spencer said.

No funding for the study was declared. The authors disclosed no relevant financial relationships.

The United States is facing a “Category 5” storm as coronavirus variants begin to spread across the country, one of the nation’s top infectious disease experts said Sunday.

“We are going to see something like we have not seen yet in this country,” Michael Osterholm, PhD, MPH, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis, said on NBC’s Meet the Press.

The United States has reported 467 cases of the coronavirus variant first identified in the United Kingdom, across 32 states, according to the CDC variant tracker. The United States has also reported three cases of the variant first identified in South Africa in South Carolina and Maryland. One case of the variant first identified in Brazil has been found in Minnesota.

Although overall COVID-19 cases and hospitalizations have declined during the past few weeks, another storm is brewing on the horizon with the variants, Dr. Osterholm told host Chuck Todd. The U.K. variant will likely cause a surge in COVID-19 cases during the next 6-14 weeks, he said. “You and I are sitting on this beach where it’s 70 degrees, perfectly blue skies, gentle breeze. But I see that hurricane 5, Category 5 or higher, 450 miles offshore. And telling people to evacuate on that nice blue sky day is going to be hard. But I can also tell you that hurricane is coming.”

Dr. Osterholm urged federal and state officials to vaccinate as many people as possible to reduce the oncoming storm. The United States has distributed 49.9 million doses and administered 31.1 million doses, according to the latest CDC data updated Sunday, including 25.2 million first doses and 5.6 million second doses.

Doling out more doses to older Americans, rather than holding onto the second dose of the two-shot regimen, is an urgent decision, Dr. Osterholm said.

“I think right now, in advance of this surge, we need to get as many one doses in as many people over 65 as we possibly can to reduce serious illnesses and deaths that are going to occur over the weeks ahead,” he said.

The U.K. variant will likely become the dominant coronavirus strain in the United States in coming weeks, Dr. Osterholm said, adding that COVID-19 vaccines should be able to protect against it. In the meantime, however, he’s worried that the variant will cause more infections and deaths until more people get vaccinated.

“What we have to do now is also anticipate this and understand that we’re going to have change quickly,” he said. “As fast as we’re opening restaurants, we’re likely going to be closing them in the near term.”

The United States is facing a “Category 5” storm as coronavirus variants begin to spread across the country, one of the nation’s top infectious disease experts said Sunday.

“We are going to see something like we have not seen yet in this country,” Michael Osterholm, PhD, MPH, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis, said on NBC’s Meet the Press.

The United States has reported 467 cases of the coronavirus variant first identified in the United Kingdom, across 32 states, according to the CDC variant tracker. The United States has also reported three cases of the variant first identified in South Africa in South Carolina and Maryland. One case of the variant first identified in Brazil has been found in Minnesota.

All patients receiving active cancer treatment should receive a COVID-19 vaccine and should be prioritized for vaccination, according to preliminary recommendations from the National Comprehensive Cancer Network (NCCN).

Vaccination timing considerations vary based on factors such as cancer and treatment type, and reasons for delaying vaccination in the general public also apply to cancer patients (recent COVID-19 exposure, for example).

In general, however, patients with cancer should be assigned to Centers for Disease Control and Prevention priority group 1 b/c and immunized when vaccination is available to them, the guidelines state. Exceptions to this recommendation include:

• Patients undergoing hematopoietic stem cell transplant or receiving engineered cellular therapy such as chimeric antigen receptor T-cell therapy. Vaccination should be delayed for at least 3 months in these patients to maximize vaccine efficacy. Caregivers of these patients, however, should be immunized when possible.
• Patients with hematologic malignancies who are receiving intensive cytotoxic chemotherapy, such as cytarabine- or anthracycline-based regimens for acute myeloid leukemia. Vaccination in these patients should be delayed until absolute neutrophil count recovery.
• Patients undergoing major surgery. Vaccination should occur at least a few days before or after surgery.
• Patients who have experienced a severe or immediate adverse reaction to any of the ingredients in the mRNA COVID-19 vaccines.

Conversely, vaccination should occur when available in patients with hematologic malignancies and marrow failure who are expected to have limited or no recovery, patients with hematologic malignancies who are on long-term maintenance therapy, and patients with solid tumors who are receiving cytotoxic chemotherapy, targeted therapy, checkpoint inhibitors and other immunotherapy, or radiotherapy.

Caregivers, household contacts, and other close contacts who are 16 years of age and older should be vaccinated whenever they are eligible.
 

Unique concerns in patients with cancer

The NCCN recommendations were developed to address the unique issues and concerns with respect to patients with cancer, who have an increased risk of severe illness from SARS-CoV-2 infection. But the guidelines come with a caveat: “[t]here are limited safety and efficacy data in these patients,” the NCCN emphasized in a press statement.

“Right now, there is urgent need and limited data,” Steven Pergam, MD, co-leader of the NCCN COVID-19 Vaccination Committee, said in the statement.

“Our number one goal is helping to get the vaccine to as many people as we can,” Dr. Pergam said. “That means following existing national and regional directions for prioritizing people who are more likely to face death or severe illness from COVID-19.”

Dr. Pergam, associate professor at Fred Hutchinson Cancer Research Center in Seattle, further explained that “people receiving active cancer treatment are at greater risk for worse outcomes from COVID-19, particularly if they are older and have additional comorbidities, like immunosuppression.”

NCCN’s recommendations couldn’t have come at a better time for patients with cancer, according to Nora Disis, MD, a professor at the University of Washington in Seattle.

“The NCCN’s recommendations to prioritize COVID vaccinations for cancer patients on active treatment is an important step forward in protecting our patients from the infection,” Dr. Disis said in an interview.

“Cancer patients may be at higher risk for the complications seen with infection. In addition, cancer is a disease of older people, and a good number of our patients have the comorbidities that would predict a poorer outcome if they should become sick,” Dr. Disis added. “With the correct treatment, many patients with cancer will be long-term survivors. It is important that they be protected from infection with COVID to realize their best outcome.”
 

Additional vaccine considerations

The NCCN recommendations also address several other issues of importance for cancer patients, including:

• Deprioritizing other vaccines. COVID-19 vaccines should take precedence over other vaccines because data on dual vaccination are lacking. The NCCN recommends waiting 14 days after COVID-19 vaccination to deliver other vaccines.
• Vaccinating clinical trial participants. Trial leads should be consulted to prevent protocol violations or exclusions.
• Decision-making in the setting of limited vaccine availability. The NCCN noted that decisions on allocation must be made in accordance with state and local vaccine guidance but suggests prioritizing appropriate patients on active treatment, those planning to start treatment, and those who have just completed treatment. Additional risk factors for these patients, as well as other factors associated with risk for adverse COVID-19 outcomes, should also be considered. These include advanced age, comorbidities, and adverse social and demographic factors such as poverty and limited health care access.
• The need for ongoing prevention measures. Vaccines have been shown to decrease the incidence of COVID-19 and related complications, but it remains unclear whether vaccines prevent infection and subsequent transmission. This means everyone should continue following prevention recommendations, such as wearing masks and avoiding crowds.

The NCCN stressed that these recommendations are “intended to be a living document that is constantly evolving – it will be updated rapidly whenever new data comes out, as well as any potential new vaccines that may get approved in the future.” The NCCN also noted that the advisory committee will meet regularly to refine the recommendations as needed.

Dr. Pergam disclosed relationships with Chimerix Inc., Merck & Co., Global Life Technologies Inc., and Sanofi-Aventis. Dr. Disis disclosed grants from Pfizer, Bavarian Nordisk, Janssen, and Precigen. She is the founder of EpiThany and editor-in-chief of JAMA Oncology.

COVID-19 infection altered the gut microbiota of adult patients and caused depletion of several types of bacteria with known immunomodulatory properties, based on data from a cohort study of 100 patients with confirmed COVID-19 infections from two hospitals.

“As the GI tract is the largest immunological organ in the body and its resident microbiota are known to modulate host immune responses, we hypothesized that the gut microbiota is associated with host inflammatory immune responses in COVID19,” wrote Yun Kit Yeoh, PhD, of the Chinese University of Hong Kong, and colleagues.

In a study published in Gut, the researchers investigated patient microbiota by collecting blood, stool, and patient records between February and May 2020 from 100 confirmed SARS-CoV-2–infected patients in Hong Kong during hospitalization, as well as follow-up stool samples from 27 patients up to 30 days after they cleared the COVID-19 virus; these observations were compared with 78 non–COVID-19 controls.

Overall, 274 stool samples were sequenced. Samples collected from patients during hospitalization for COVID-19 were compared with non–COVID-19 controls. The presence of phylum Bacteroidetes was significantly higher in COVID-19 patients compared with controls (23.9% vs. 12.8%; P < .001), as were Actinobacteria (26.1% vs. 19.0%; P < .001).

After controlling for antibiotics, the investigators found that “differences between cohorts were primarily linked to enrichment of taxa such as Parabacteroides, Sutterella wadsworthensis, and Bacteroides caccae and depletion of Adlercreutzia equolifaciens, Dorea formicigenerans, and Clostridium leptum in COVID-19 relative to non-COVID-19” (P < .05). In addition, Faecalibacterium prausnitzii and Bifidobacterium bifidum were negatively correlated with COVID-19 severity after investigators controlled for patient age and antibiotic use (P < .05).

The researchers also examined bacteria in COVID-19 patients and controls in the context of cytokines and other inflammatory markers. “We hypothesized that these compositional changes play a role in exacerbating disease by contributing to dysregulation of the immune response,” they said.

In fact, species depleted in COVID-19 patients including included B. adolescentis, E. rectale, and F. prausnitzii were negatively correlated with inflammatory markers including CXCL10, IL-10, TNF-alpha, and CCL2.

In addition, 42 stool samples from 27 patients showed significantly distinct gut microbiota from controls up to 30 days (median, 6 days) after virus clearance, regardless of antibiotics use (P < .05), the researchers said.
 

Long-term data needed

The study findings were limited by several factors, including the potential confounding of microbial signatures associated with COVID-19 because of heterogeneous patient management in the clinical setting and the potential that gut microbiota reflects a patient’s health with no impact on disease severity, as well as lack of data on the role of antibiotics for severe and critical patients, the researchers noted. In addition, “gut microbiota composition is highly heterogeneous across human populations and changes in compositions reported here may not necessarily be reflected in patients with COVID-19 from other biogeographies,” they wrote.

The “longer follow-up of patients with COVID-19 (e.g., 3 months to 1 year after clearing the virus) is needed to address questions related to the duration of gut microbiota dysbiosis post recovery, link between microbiota dysbiosis and long-term persistent symptoms, and whether the dysbiosis or enrichment/depletion of specific gut microorganisms predisposes recovered individuals to future health problems,” they wrote.

However, the results suggest a likely role for gut microorganisms in host inflammatory responses to COVID-19 infection, and “underscore an urgent need to understand the specific roles of gut microorganisms in human immune function and systemic inflammation,” they concluded.
 

More than infectious

“A growing body of evidence suggests that severity of illness from COVID-19 is largely determined by the patient’s aberrant immune response to the virus,” Jatin Roper, MD, of Duke University, Durham, N.C., said in an interview. “Therefore, a critical question is: What patient factors determine this immune response? The gut microbiota closely interact with the host immune system and are altered in many immunological diseases,” he said. “Furthermore, the SARS-CoV-2 virus infects enterocytes in the intestine and causes symptomatic gastrointestinal disease in a subset of patients. Therefore, understanding a possible association between gut microbiota and COVID-19 may reveal microbial species involved in disease pathogenesis,” he emphasized.   

In the current study, “I was surprised to find that COVID-19 infection is associated with depletion of immunomodulatory gut bacteria,” said Dr. Roper. “An open question is whether these changes are caused by the SARS-CoV-2 virus and then result in altered immune response. Alternatively, the changes in gut microbiota may be a result of the immune response or other changes associated with the disease,” he said.

“COVID-19 is an immunological disease, not just an infectious disease,” explained Dr. Roper. “The gut microbiota may play an important role in the pathogenesis of the disease. Thus, specific gut microbes could one day be analyzed to risk stratify patients, or even modified to treat the disease,” he noted.
 

Beyond COVID-19

“Given the impact of the gut microbiota on health and disease, as well as the impact of diseases on the microbiota, I am not at all surprised to find that there were significant changes in the microbiota of COVID-19 patients and that these changes are associated with inflammatory cytokines, chemokines, and blood markers of tissue damage,” said Anthony Sung, MD, also of Duke University.

According to Dr. Sung, researchers have already been investigating possible connections between gut microbiota and other conditions such as Alzheimer’s disease, and it’s been hypothesized that these connections are mediated by interactions between the gut microbiota and the immune system.

“While this is an important paper in our understanding of COVID-19, and highlights the microbiome as a potential therapeutic target, we need to conduct clinical trials of microbiota-based interventions before we can fully realize the clinical implications of these findings,” he said.

The study was supported by the Health and Medical Research Fund, the Food and Health Bureau, The Government of the Hong Kong Special Administrative Region, and donations from Hui Hoy & Chow Sin Lan Charity Fund Limited, Pine and Crane Company Limited, Mr. Hui Ming, and The D.H. Chen Foundation. The researchers had no financial conflicts to disclose. Dr. Roper and Dr. Sung had no financial conflicts to disclose.

“While this is an important paper in our understanding of COVID-19, and highlights the microbiome as a potential therapeutic target, we need to conduct clinical trials of microbiota-based interventions before we can fully realize the clinical implications of these findings,” he said.

The study was supported by the Health and Medical Research Fund, the Food and Health Bureau, The Government of the Hong Kong Special Administrative Region, and donations from Hui Hoy & Chow Sin Lan Charity Fund Limited, Pine and Crane Company Limited, Mr. Hui Ming, and The D.H. Chen Foundation. The researchers had no financial conflicts to disclose. Dr. Roper and Dr. Sung had no financial conflicts to disclose.

COVID-19 infection altered the gut microbiota of adult patients and caused depletion of several types of bacteria with known immunomodulatory properties, based on data from a cohort study of 100 patients with confirmed COVID-19 infections from two hospitals.

“As the GI tract is the largest immunological organ in the body and its resident microbiota are known to modulate host immune responses, we hypothesized that the gut microbiota is associated with host inflammatory immune responses in COVID19,” wrote Yun Kit Yeoh, PhD, of the Chinese University of Hong Kong, and colleagues.

In a study published in Gut, the researchers investigated patient microbiota by collecting blood, stool, and patient records between February and May 2020 from 100 confirmed SARS-CoV-2–infected patients in Hong Kong during hospitalization, as well as follow-up stool samples from 27 patients up to 30 days after they cleared the COVID-19 virus; these observations were compared with 78 non–COVID-19 controls.

Overall, 274 stool samples were sequenced. Samples collected from patients during hospitalization for COVID-19 were compared with non–COVID-19 controls. The presence of phylum Bacteroidetes was significantly higher in COVID-19 patients compared with controls (23.9% vs. 12.8%; P < .001), as were Actinobacteria (26.1% vs. 19.0%; P < .001).

After controlling for antibiotics, the investigators found that “differences between cohorts were primarily linked to enrichment of taxa such as Parabacteroides, Sutterella wadsworthensis, and Bacteroides caccae and depletion of Adlercreutzia equolifaciens, Dorea formicigenerans, and Clostridium leptum in COVID-19 relative to non-COVID-19” (P < .05). In addition, Faecalibacterium prausnitzii and Bifidobacterium bifidum were negatively correlated with COVID-19 severity after investigators controlled for patient age and antibiotic use (P < .05).

The researchers also examined bacteria in COVID-19 patients and controls in the context of cytokines and other inflammatory markers. “We hypothesized that these compositional changes play a role in exacerbating disease by contributing to dysregulation of the immune response,” they said.

In fact, species depleted in COVID-19 patients including included B. adolescentis, E. rectale, and F. prausnitzii were negatively correlated with inflammatory markers including CXCL10, IL-10, TNF-alpha, and CCL2.

In addition, 42 stool samples from 27 patients showed significantly distinct gut microbiota from controls up to 30 days (median, 6 days) after virus clearance, regardless of antibiotics use (P < .05), the researchers said.
 

Long-term data needed

The study findings were limited by several factors, including the potential confounding of microbial signatures associated with COVID-19 because of heterogeneous patient management in the clinical setting and the potential that gut microbiota reflects a patient’s health with no impact on disease severity, as well as lack of data on the role of antibiotics for severe and critical patients, the researchers noted. In addition, “gut microbiota composition is highly heterogeneous across human populations and changes in compositions reported here may not necessarily be reflected in patients with COVID-19 from other biogeographies,” they wrote.

The “longer follow-up of patients with COVID-19 (e.g., 3 months to 1 year after clearing the virus) is needed to address questions related to the duration of gut microbiota dysbiosis post recovery, link between microbiota dysbiosis and long-term persistent symptoms, and whether the dysbiosis or enrichment/depletion of specific gut microorganisms predisposes recovered individuals to future health problems,” they wrote.

However, the results suggest a likely role for gut microorganisms in host inflammatory responses to COVID-19 infection, and “underscore an urgent need to understand the specific roles of gut microorganisms in human immune function and systemic inflammation,” they concluded.
 

More than infectious

“A growing body of evidence suggests that severity of illness from COVID-19 is largely determined by the patient’s aberrant immune response to the virus,” Jatin Roper, MD, of Duke University, Durham, N.C., said in an interview. “Therefore, a critical question is: What patient factors determine this immune response? The gut microbiota closely interact with the host immune system and are altered in many immunological diseases,” he said. “Furthermore, the SARS-CoV-2 virus infects enterocytes in the intestine and causes symptomatic gastrointestinal disease in a subset of patients. Therefore, understanding a possible association between gut microbiota and COVID-19 may reveal microbial species involved in disease pathogenesis,” he emphasized.   

In the current study, “I was surprised to find that COVID-19 infection is associated with depletion of immunomodulatory gut bacteria,” said Dr. Roper. “An open question is whether these changes are caused by the SARS-CoV-2 virus and then result in altered immune response. Alternatively, the changes in gut microbiota may be a result of the immune response or other changes associated with the disease,” he said.

“COVID-19 is an immunological disease, not just an infectious disease,” explained Dr. Roper. “The gut microbiota may play an important role in the pathogenesis of the disease. Thus, specific gut microbes could one day be analyzed to risk stratify patients, or even modified to treat the disease,” he noted.
 

Beyond COVID-19

“Given the impact of the gut microbiota on health and disease, as well as the impact of diseases on the microbiota, I am not at all surprised to find that there were significant changes in the microbiota of COVID-19 patients and that these changes are associated with inflammatory cytokines, chemokines, and blood markers of tissue damage,” said Anthony Sung, MD, also of Duke University.

More people with fever and body aches are turning to NSAIDs to ease symptoms, but the drugs have come under new scrutiny as investigators work to determine whether they are a safe way to relieve the pain of COVID-19 vaccination or symptoms of the disease.

Early on in the pandemic, French health officials warned that NSAIDs, such as ibuprofen, could worsen coronavirus disease, and they recommended switching to acetaminophen instead.

The National Health Service in the United Kingdom followed with a similar recommendation for acetaminophen.

But the European Medicines Agency took a different approach, reporting “no scientific evidence” that NSAIDs could worsen COVID-19. The U.S. Food and Drug Administration also opted not to take a stance.

The debate prompted discussion on social media, with various reactions from around the world. It also inspired Craig Wilen, MD, PhD, from Yale University, New Haven, Conn., and associates to examine the effect of NSAIDs on COVID-19 infection and immune response. Their findings were published online Jan.20 in the Journal of Virology.

“It really bothered me that non–evidence-based decisions were driving the conversation,” Dr. Wilen said. “Millions of people are taking NSAIDs every day and clinical decisions about their care shouldn’t be made on a hypothesis.”

One theory is that NSAIDs alter susceptibility to infection by modifying ACE2. The drugs might also change the cell entry receptor for SARS-CoV-2, alter virus replication, or even modify the immune response.

British researchers, also questioning the safety of NSAIDs in patients with COVID-19, delved into National Health Service records to study two large groups of patients, some of whom were taking the pain relievers.

“We were watching the controversy and the lack of evidence and wanted to contribute,” lead investigator Angel Wong, PhD, from the London School of Hygiene and Tropical Medicine, said in an interview.

And with nearly 11 million NSAID prescriptions dispensed in primary care in England alone in the past 12 months, the inconsistency was concerning.

The team compared COVID-19–related deaths in two groups: one group of more than 700,000 people taking NSAIDs, including patients with rheumatoid arthritis and osteoarthritis; and another of almost 3.5 million people not on the medication.

NSAIDs work by inhibiting cyclooxygenase-1 and COX-2 enzymes in the body, which are crucial for the generation of prostaglandins. These lipid molecules play a role in inflammation and are blocked by NSAIDs.

The investigators found no evidence of a harmful effect of NSAIDs on COVID-19-related deaths; their results were published online Jan. 21 in the Annals of the Rheumatic Diseases.

The results, they pointed out, are in line with a Danish study that also showed no evidence of a higher risk for severe COVID-19 outcomes with NSAID use.

“It’s reassuring,” Dr. Wong said, “that patients can safely continue treatment.”
 

More new evidence

Dr. Wilen’s team found that SARS-CoV-2 infection stimulated COX-2 expression in human and mice cells. However, suppression of COX-2 by two commonly used NSAIDs, ibuprofen and meloxicam, had no effect on ACE2 expression, viral entry, or viral replication.

In their mouse model of SARS-CoV-2 infection, the investigators saw that NSAIDs impaired the production of proinflammatory cytokines and neutralizing antibodies. The findings suggest that NSAIDs influence COVID-19 outcomes by dampening the inflammatory response and production of protective antibodies, rather than modifying susceptibility to infection or viral replication.

Understanding the effect of NSAIDs on cytokine production is critical, Dr. Wilen pointed out, because they might be protective early in COVID-19 but pathologic at later stages.

Timing is crucial in the case of other immunomodulatory drugs. For example, dexamethasone lowers mortality in COVID-19 patients on respiratory support but is potentially harmful for those with milder disease.

There still is a lot to learn, Dr. Wilen acknowledged. “We may be seeing something similar going on with NSAIDs, where the timing of treatment is important.”

Antibodies against SARS-CoV-2 cross the placenta during pregnancy and are detectable in most newborns born to mothers who had COVID-19 during pregnancy, according to findings from a study presented Jan. 28 at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“I think the most striking finding is that we noticed a high degree of neutralizing response to natural infection even among asymptomatic infection, but of course a higher degree was seen in those with symptomatic infection,” Naima Joseph, MD, MPH, of Emory University, Atlanta, said in an interview.

“Our data demonstrate maternal capacity to mount an appropriate and robust immune response,” and maternal protective immunity lasted at least 28 days after infection, Dr. Joseph said. “Also, we noted higher neonatal cord blood titers in moms with higher titers, which suggests a relationship, but we need to better understand how transplacental transfer occurs as well as establish neonatal correlates of protection in order to see if and how maternal immunity may also benefit neonates.”

The researchers analyzed the amount of IgG and IgM antibodies in maternal and cord blood samples prospectively collected at delivery from women who tested positive for COVID-19 at any time while pregnant. They used enzyme-linked immunosorbent assay to assess for antibodies for the receptor binding domain of the SARS-CoV-2 spike protein.

The 32 pairs of mothers and infants in the study were predominantly non-Hispanic Black (72%) and Hispanic (25%), and 84% used Medicaid as their payer. Most of the mothers (72%) had at least one comorbidity, most commonly obesity, hypertension, and asthma or pulmonary disease. Just over half the women (53%) were symptomatic while they were infected, and 88% were ill with COVID-19 during the third trimester. The average time from infection to delivery was 28 days.

All the mothers had IgG antibodies, 94% had IgM antibodies, and 94% had neutralizing antibodies against SARS-CoV-2. Among the cord blood samples, 91% had IgG antibodies, 9% had IgM antibodies, and 25% had neutralizing antibodies.

“It’s reassuring that, so far, the physiological response is exactly what we expected it to be,” Judette Louis, MD, MPH, an associate professor of ob.gyn. and the ob.gyn. department chair at the University of South Florida, Tampa, said in an interview. “It’s what we would expect, but it’s always helpful to have more data to support that. Otherwise, you’re extrapolating from what you know from other conditions,” said Dr. Louis, who moderated the oral abstracts session.

Symptomatic infection was associated with significantly higher IgG titers than asymptomatic infection (P = .03), but no correlation was seen for IgM or neutralizing antibodies. In addition, although mothers who delivered more than 28 days after their infection had higher IgG titers (P = .05), no differences existed in IgM or neutralizing response.

Infants’ cord blood titers were significantly lower than their corresponding maternal samples, independently of symptoms or latency from infection to delivery (P < .001), Dr. Joseph reported.

“Transplacental efficiency in other pathogens has been shown to be correlated with neonatal immunity when the ratio of cord to maternal blood is greater than 1,” Dr. Joseph said in her presentation. Their data showed “suboptimal efficiency” at a ratio of 0.81.

The study’s small sample size and lack of a control group were weaknesses, but a major strength was having a population at disproportionately higher risk for infection and severe morbidity than the general population.
 

Implications for maternal COVID-19 vaccination

Although the data are not yet available, Dr. Joseph said they have expanded their protocol to include vaccinated pregnant women.

“The key to developing an effective vaccine [for pregnant people] is in really characterizing adaptive immunity in pregnancy,” Dr. Joseph told SMFM attendees. “I think that these findings inform further vaccine development in demonstrating that maternal immunity is robust.”

The World Health Organization recently recommended withholding COVID-19 vaccines from pregnant people, but the SMFM and American College of Obstetricians and Gynecologists subsequently issued a joint statement reaffirming that the COVID-19 vaccines authorized by the FDA “should not be withheld from pregnant individuals who choose to receive the vaccine.”

“One of the questions people ask is whether in pregnancy you’re going to mount a good response to the vaccine the way you would outside of pregnancy,” Dr. Louis said. “If we can demonstrate that you do, that may provide the information that some mothers need to make their decisions.” Data such as those from Dr. Joseph’s study can also inform recommendations on timing of maternal vaccination.

“For instance, Dr. Joseph demonstrated that, 28 days out from the infection, you had more antibodies, so there may be a scenario where we say this vaccine may be more beneficial in the middle of the pregnancy for the purpose of forming those antibodies,” Dr. Louis said.
 

Consensus emerging from maternal antibodies data

The findings from Dr. Joseph’s study mirror those reported in a study published online Jan. 29 in JAMA Pediatrics. That study, led by Dustin D. Flannery, DO, MSCE, of Children’s Hospital of Philadelphia, also examined maternal and neonatal levels of IgG and IgM antibodies against the receptor binding domain of the SARS-CoV-2 spike protein. They also found a positive correlation between cord blood and maternal IgG concentrations (P < .001), but notably, the ratio of cord to maternal blood titers was greater than 1, unlike in Dr. Joseph’s study.

For their study, Dr. Flannery and colleagues obtained maternal and cord blood sera at the time of delivery from 1471 pairs of mothers and infants, independently of COVID status during pregnancy. The average maternal age was 32 years, and just over a quarter of the population (26%) were Black, non-Hispanic women. About half (51%) were White, 12% were Hispanic, and 7% were Asian.

About 6% of the women had either IgG or IgM antibodies at delivery, and 87% of infants born to those mothers had measurable IgG in their cord blood. No infants had IgM antibodies. As with the study presented at SMFM, the mothers’ infections included asymptomatic, mild, moderate, and severe cases, and the degree of severity of cases had no apparent effect on infant antibody concentrations. Most of the women who tested positive for COVID-19 (60%) were asymptomatic.

Among the 11 mothers who had antibodies but whose infants’ cord blood did not, 5 had only IgM antibodies, and 6 had significantly lower IgG concentrations than those seen in the other mothers.

In a commentary about the JAMA Pediatrics study, Flor Munoz, MD, of the Baylor College of Medicine, Houston, suggested that the findings are grounds for optimism about a maternal vaccination strategy to protect infants from COVID-19.

“However, the timing of maternal vaccination to protect the infant, as opposed to the mother alone, would necessitate an adequate interval from vaccination to delivery (of at least 4 weeks), while vaccination early in gestation and even late in the third trimester could still be protective for the mother,” Dr. Munoz wrote.

Given the interval between two-dose vaccination regimens and the fact that transplacental transfer begins at about the 17th week of gestation, “maternal vaccination starting in the early second trimester of gestation might be optimal to achieve the highest levels of antibodies in the newborn,” Dr. Munoz wrote. But questions remain, such as how effective the neonatal antibodies would be in protecting against COVID-19 and how long they last after birth.

No external funding was used in Dr. Joseph’s study. Dr. Joseph and Dr. Louis have disclosed no relevant financial relationships. The JAMA Pediatrics study was funded by the Children’s Hospital of Philadelphia. One coauthor received consultancy fees from Sanofi Pasteur, Lumen, Novavax, and Merck unrelated to the study. Dr. Munoz served on the data and safety monitoring boards of Moderna, Pfizer, Virometix, and Meissa Vaccines and has received grants from Novavax Research and Gilead Research.

No external funding was used in Dr. Joseph’s study. Dr. Joseph and Dr. Louis have disclosed no relevant financial relationships.

Antibodies against SARS-CoV-2 cross the placenta during pregnancy and are detectable in most newborns born to mothers who had COVID-19 during pregnancy, according to findings from a study presented Jan. 28 at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“I think the most striking finding is that we noticed a high degree of neutralizing response to natural infection even among asymptomatic infection, but of course a higher degree was seen in those with symptomatic infection,” Naima Joseph, MD, MPH, of Emory University, Atlanta, said in an interview.

“Our data demonstrate maternal capacity to mount an appropriate and robust immune response,” and maternal protective immunity lasted at least 28 days after infection, Dr. Joseph said. “Also, we noted higher neonatal cord blood titers in moms with higher titers, which suggests a relationship, but we need to better understand how transplacental transfer occurs as well as establish neonatal correlates of protection in order to see if and how maternal immunity may also benefit neonates.”

The researchers analyzed the amount of IgG and IgM antibodies in maternal and cord blood samples prospectively collected at delivery from women who tested positive for COVID-19 at any time while pregnant. They used enzyme-linked immunosorbent assay to assess for antibodies for the receptor binding domain of the SARS-CoV-2 spike protein.

The 32 pairs of mothers and infants in the study were predominantly non-Hispanic Black (72%) and Hispanic (25%), and 84% used Medicaid as their payer. Most of the mothers (72%) had at least one comorbidity, most commonly obesity, hypertension, and asthma or pulmonary disease. Just over half the women (53%) were symptomatic while they were infected, and 88% were ill with COVID-19 during the third trimester. The average time from infection to delivery was 28 days.

All the mothers had IgG antibodies, 94% had IgM antibodies, and 94% had neutralizing antibodies against SARS-CoV-2. Among the cord blood samples, 91% had IgG antibodies, 9% had IgM antibodies, and 25% had neutralizing antibodies.

“It’s reassuring that, so far, the physiological response is exactly what we expected it to be,” Judette Louis, MD, MPH, an associate professor of ob.gyn. and the ob.gyn. department chair at the University of South Florida, Tampa, said in an interview. “It’s what we would expect, but it’s always helpful to have more data to support that. Otherwise, you’re extrapolating from what you know from other conditions,” said Dr. Louis, who moderated the oral abstracts session.

Symptomatic infection was associated with significantly higher IgG titers than asymptomatic infection (P = .03), but no correlation was seen for IgM or neutralizing antibodies. In addition, although mothers who delivered more than 28 days after their infection had higher IgG titers (P = .05), no differences existed in IgM or neutralizing response.

Infants’ cord blood titers were significantly lower than their corresponding maternal samples, independently of symptoms or latency from infection to delivery (P < .001), Dr. Joseph reported.

“Transplacental efficiency in other pathogens has been shown to be correlated with neonatal immunity when the ratio of cord to maternal blood is greater than 1,” Dr. Joseph said in her presentation. Their data showed “suboptimal efficiency” at a ratio of 0.81.

The study’s small sample size and lack of a control group were weaknesses, but a major strength was having a population at disproportionately higher risk for infection and severe morbidity than the general population.
 

Implications for maternal COVID-19 vaccination

Although the data are not yet available, Dr. Joseph said they have expanded their protocol to include vaccinated pregnant women.

“The key to developing an effective vaccine [for pregnant people] is in really characterizing adaptive immunity in pregnancy,” Dr. Joseph told SMFM attendees. “I think that these findings inform further vaccine development in demonstrating that maternal immunity is robust.”

The World Health Organization recently recommended withholding COVID-19 vaccines from pregnant people, but the SMFM and American College of Obstetricians and Gynecologists subsequently issued a joint statement reaffirming that the COVID-19 vaccines authorized by the FDA “should not be withheld from pregnant individuals who choose to receive the vaccine.”

“One of the questions people ask is whether in pregnancy you’re going to mount a good response to the vaccine the way you would outside of pregnancy,” Dr. Louis said. “If we can demonstrate that you do, that may provide the information that some mothers need to make their decisions.” Data such as those from Dr. Joseph’s study can also inform recommendations on timing of maternal vaccination.

“For instance, Dr. Joseph demonstrated that, 28 days out from the infection, you had more antibodies, so there may be a scenario where we say this vaccine may be more beneficial in the middle of the pregnancy for the purpose of forming those antibodies,” Dr. Louis said.
 

Consensus emerging from maternal antibodies data

The findings from Dr. Joseph’s study mirror those reported in a study published online Jan. 29 in JAMA Pediatrics. That study, led by Dustin D. Flannery, DO, MSCE, of Children’s Hospital of Philadelphia, also examined maternal and neonatal levels of IgG and IgM antibodies against the receptor binding domain of the SARS-CoV-2 spike protein. They also found a positive correlation between cord blood and maternal IgG concentrations (P < .001), but notably, the ratio of cord to maternal blood titers was greater than 1, unlike in Dr. Joseph’s study.

For their study, Dr. Flannery and colleagues obtained maternal and cord blood sera at the time of delivery from 1471 pairs of mothers and infants, independently of COVID status during pregnancy. The average maternal age was 32 years, and just over a quarter of the population (26%) were Black, non-Hispanic women. About half (51%) were White, 12% were Hispanic, and 7% were Asian.

About 6% of the women had either IgG or IgM antibodies at delivery, and 87% of infants born to those mothers had measurable IgG in their cord blood. No infants had IgM antibodies. As with the study presented at SMFM, the mothers’ infections included asymptomatic, mild, moderate, and severe cases, and the degree of severity of cases had no apparent effect on infant antibody concentrations. Most of the women who tested positive for COVID-19 (60%) were asymptomatic.

Among the 11 mothers who had antibodies but whose infants’ cord blood did not, 5 had only IgM antibodies, and 6 had significantly lower IgG concentrations than those seen in the other mothers.

In a commentary about the JAMA Pediatrics study, Flor Munoz, MD, of the Baylor College of Medicine, Houston, suggested that the findings are grounds for optimism about a maternal vaccination strategy to protect infants from COVID-19.

“However, the timing of maternal vaccination to protect the infant, as opposed to the mother alone, would necessitate an adequate interval from vaccination to delivery (of at least 4 weeks), while vaccination early in gestation and even late in the third trimester could still be protective for the mother,” Dr. Munoz wrote.

Given the interval between two-dose vaccination regimens and the fact that transplacental transfer begins at about the 17th week of gestation, “maternal vaccination starting in the early second trimester of gestation might be optimal to achieve the highest levels of antibodies in the newborn,” Dr. Munoz wrote. But questions remain, such as how effective the neonatal antibodies would be in protecting against COVID-19 and how long they last after birth.

New data on COVID-19 vaccines should serve as a “wake-up call” about the need to stop the spread of the SARS-CoV-2 virus among people and thus deprive it of opportunities to evolve its defenses, the top federal expert on infectious diseases said.

“The virus will continue to mutate and will mutate for its own selective advantage,” said Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, at a Friday news conference organized by the White House.

The continued transmission of SARS-CoV-2 “gives the virus the chance to adapt to the forces, in this case the immune response, that’s trying to get rid of it,” Dr. Fauci said. “That’s where you get mutations.”

Federal health officials are working to boost the U.S. supply of COVID-19 vaccines, even as signals emerge about the extent that the virus is already evolving.

Data released this week about the Janssen/Johnson & Johnson (J&J) and Novavax COVID-19 vaccines in late-stage development provides further evidence that they may not protect as well against emerging variants, Dr. Fauci said.

“Mutations that lead to different lineage do have clinical consequences,” he said, while also emphasizing that the emerging vaccines appear to confer broad protection. Dr. Fauci earlier in the day addressed the “messaging challenge” for clinicians and researchers in discussing the results of the J&J vaccine trial, which appear to fall short of those reported for the two vaccines already approved and in use in the United States. He noted the benefits of possibly soon having more authorized vaccines to combat COVID-19. But continued community spread of the infection will foster conditions that can undermine the vaccines’ effectiveness.

“Even though the long-range effect in the sense of severe disease is still handled reasonably well by the vaccines, this is a wake-up call to all of us,” Dr. Fauci said.

Pharmaceutical scientists and executives and government health officials will need to work together to continue to develop vaccines that can outwit the emerging variants, he said.

On Jan. 29, J&J reported that its highly anticipated single-dose vaccine had shown its worst results in South Africa where many cases of COVID-19 were caused by infection with a SARS-CoV-2 variant from the B.1.351 lineage. The overall efficacy was 66% globally, 72% in the United States, and 57% in South Africa against moderate to severe SARS-CoV-2, J&J said.

Novavax on Jan. 28 reported an efficacy rate for its COVID-19 vaccine of 49.4% from a clinical trial conducted in South Africa, compared with an 89.3% rate from a U.K. study. There already have been attempts to estimate how well the Pfizer/BioNTech and Moderna vaccines can handle new variants of the virus. They both have been granted emergency-use authorization by the U.S. Food and Drug Administration.
 

‘Genomic surveillance’

The Centers for Disease Control and Prevention on Thursday reported the first U.S.-documented cases of the B.1.351 variant of SARS-CoV-2 in South Carolina. On Jan. 26, the first confirmed U.S. case of a highly transmissible Brazilian coronavirus variant was detected in Minnesota, state health officials said.

The CDC’s stepped-up “genomic surveillance” will help keep clinicians and researchers aware of how SARS-CoV-2 is changing, Dr. Fauci said.

Speaking at the same White House news conference, CDC director Rochelle Walensky, MD, MPH, said the two South Carolina cases of the B.1.351 variant were reported in different parts of the state and not believed to be epidemiologically linked. The people involved “did not have any travel history,” she added.

The SARS-CoV-2 mutations were expected to emerge at some point, as with any virus, but their appearance underscores the need for people to remain vigilant about precautions that can stop its spread, Dr. Walensky said.

She and Dr. Fauci both stressed the need for continued use of masks and social distancing and urged people to get COVID-19 vaccines as they become available. Continued community spread of the virus allows this global health threat to keep replicating, and thus increases its chances to thwart medical interventions, Dr. Fauci said.

“The virus has a playing field, as it were, to mutate,” Dr. Fauci said. “If you stop that and stop the replication, the viruses cannot mutate if they don’t replicate.”

An international team of researchers studying COVID-19 has made a startling and pivotal discovery: The virus appears to cause the body to make weapons to attack its own tissues.

The finding could unlock a number of COVID-19’s clinical mysteries. They include the puzzling collection of symptoms that can come with the infection; the persistence of symptoms in some people for months after they clear the virus, a phenomenon dubbed long COVID-19; and why some children and adults have a serious inflammatory syndrome, called multisystem inflammatory syndrome in children (MIS-C) or MIS in adults (MIS-A), after their infections.

“It suggests that the virus might be directly causing autoimmunity, which would be fascinating,” says lead study author Paul Utz, MD, who studies immunology and autoimmunity at Stanford (Calif.) University.

The study also deepens the question of whether other respiratory viruses might also break the body’s tolerance to itself, setting people up for autoimmune diseases like multiple sclerosis, rheumatoid arthritis, and lupus later in life.

Dr. Utz said he and his team are next going to study flu patients to see if that virus might also cause this phenomenon.

“My prediction is that it isn’t going to be specific just to SARS-CoV-2. I’m willing to bet that we will find this with other respiratory viruses,” he said.

The study comes on the heels of a handful of smaller, detailed investigations that have come to similar conclusions.

The study included data from more than 300 patients from four hospitals: two in California, one in Pennsylvania, and another in Germany.

Researchers used blood tests to study their immune responses as their infections progressed. Researchers looked for autoantibodies – weapons of the immune system that go rogue and launch an attack against the body’s own tissues. They compared these autoantibodies with those found in people who were not infected with the virus that causes COVID.

As previous studies have found, autoantibodies were more common after COVID – 50% of people hospitalized for their infections had autoantibodies, compared with less than 15% of those who were healthy and uninfected.

Some people with autoantibodies had little change in them as their infections progressed. That suggests the autoantibodies were there to begin with, possibly allowing the infection to burn out of control in the body.

“Their body is set up to get bad COVID, and it’s probably caused by the autoantibodies,” Dr. Utz said.

But in others, about 20% of people who had them, the autoantibodies became more common as the infection progressed, suggesting they were directly related to the viral infection, instead of being a preexisting condition.

Some of these were antibodies that attack key components of the immune system’s weapons against the virus, like interferon. Interferons are proteins that help infected cells call for reinforcements and can also interfere with a virus’s ability to copy itself. Taking them out is a powerful evasive tactic, and previous studies have shown that people who are born with genes that cause them to have lower interferon function, or who make autoantibodies against these proteins, appear to be at higher risk for life-threatening COVID infections.

“It seems to give the virus a powerful advantage,” said study author, John Wherry, PhD, who directs the Institute for Immunology at the University of Pennsylvania, Philadelphia. “Now your immune system, instead of having a tiny little hill to climb, is staring at Mount Everest. That really is devious.”

In addition to those that sabotage the immune system, some people in the study had autoantibodies against muscles and connective tissues that are seen in some rare disorders.

Dr. Utz said they started the study after seeing COVID patients with strange collections of symptoms that looked more like autoimmune diseases than viral infections – skin rashes, joint pain, fatigue, aching muscles, brain swelling, dry eyes, blood that clots easily, and inflamed blood vessels.

“One thing that’s very important to note is that we don’t know if these patients are going to go on to develop autoimmune disease,” Dr. Utz said. “I think we’ll be able to answer that question in the next 6-12 months as we follow the long haulers and study their samples.”

Dr. Utz said it will be important to study autoantibodies in long haulers to see if they can identify exactly which ones seem to be at work in the condition. If you can catch them early, it might be possible to treat those at risk for enduring symptoms with drugs that suppress the immune system.

What this means, he said, is that COVID will be with us for a long, long time.

“We have to realize that there’s going to be long-term damage from this virus for the survivors. Not just the long haulers, but all the people who have lung damage and heart damage and everything else. We’re going to be studying this virus and it’s badness for decades,” Dr. Utz said.

Dr. Utz said they started the study after seeing COVID patients with strange collections of symptoms that looked more like autoimmune diseases than viral infections – skin rashes, joint pain, fatigue, aching muscles, brain swelling, dry eyes, blood that clots easily, and inflamed blood vessels.

“One thing that’s very important to note is that we don’t know if these patients are going to go on to develop autoimmune disease,” Dr. Utz said. “I think we’ll be able to answer that question in the next 6-12 months as we follow the long haulers and study their samples.”

Dr. Utz said it will be important to study autoantibodies in long haulers to see if they can identify exactly which ones seem to be at work in the condition. If you can catch them early, it might be possible to treat those at risk for enduring symptoms with drugs that suppress the immune system.

What this means, he said, is that COVID will be with us for a long, long time.

“We have to realize that there’s going to be long-term damage from this virus for the survivors. Not just the long haulers, but all the people who have lung damage and heart damage and everything else. We’re going to be studying this virus and it’s badness for decades,” Dr. Utz said.

Long-acting injectable antipsychotics (LAIs) are an essential tool in the treatment of patients with psychotic disorders, allowing for periods of stable drug plasma concentration and confirmed adherence.¹ The current coronavirus disease 2019 (COVID-19) pandemic presents unique challenges for administering LAIs and requires a thoughtful and prospective approach in order to ensure continuity of psychiatric care while minimizing the risk of infection with COVID-19. Ideally, patients should be seen in person as infrequently as clinically prudent during this public health emergency; however, LAI administration necessitates direct physical contact between patient and clinician.

Patients with serious mental illness (SMI), who comprise the majority of individuals who receive LAIs, are at heightened risk for cardiovascular and pulmonary comorbidities. These factors are the primary reason the life expectancy of a patient with SMI is nearly 30 years shorter than that of the general population.^2-5 The risk of health care workers becoming infected or inadvertently spreading COVID-19 is heightened when working with patients in group living environments (ie, a shelter or group home), who have both increased exposure and increased risk of further transmission.⁶ Additional patient populations, including older adults, immunocompromised individuals, and those with preexisting conditions, are at heightened risk for serious complications if they were to contract COVID-19.^7,8

Thus, the questions of whether LAIs should be administered, and how to do so safely (both during the ongoing, acute phase of the pandemic as well as during the subsequent recovery period until the pandemic abates) need to be carefully considered. In this article, we provide concrete advice for clinicians and clinics on these topics, with the goal of maintaining patients’ psychiatric stability while protecting patients, health care workers, and the broader society from COVID-19 infection. Table 1 summarizes the questions regarding LAIs that clinicians need to address during this crisis. While we focus on outpatient care, inpatient teams should keep these considerations in mind if they are starting and discharging a patient on an LAI. More than ever, close collaboration and communication between inpatient and outpatient teams is critical.

Should an LAI be continued?

An important first step to approaching this challenge is to create a spreadsheet for all patients receiving LAIs. Focusing on a population-based approach is helpful to be systematic and ensure that no patients fall through the cracks during this public health emergency.⁹ Once all patients have been identified, the treatment team should review each patient to determine if continuing to administer the antipsychotic as an LAI formulation is essential, taking into account the patient’s current psychiatric status, historical medication adherence, potential severity and dangerousness of decompensation if nonadherent, and structures to support stability. For example, can a patient move in with family who can monitor medication adherence during the pandemic? Is it possible for the group home to assume medication administration? Additional consideration should be given to the living environment and health-vulnerability of the patient and the individuals living with them.

If the risk calculation does not point strongly towards a need for continuing the LAI, it may be prudent to temporarily transition the patient to the corresponding oral antipsychotic preparation. Table 2 lists all LAIs available in the United States and their approximate equivalent oral dosing. It is important to note that such transitions are not without clinical risk, to emphasize to the patient that the transition is intended as a temporary measure, and to discuss a proposed timeline for re-initiating the LAI. Also, emphasize to the patient and family that this transition does not diminish the previous reasoning for needing an LAI, but is a temporary measure taken in light of weighing the risks and benefits during a pandemic.

Which LAI should be administered?

If continuing the LAI is determined to be clinically necessary, consider switching the patient to a longer-acting preparation to maximize intervals between administrations and minimize the potential for infection. From a public health perspective, the longest clinically prudent interval between injections may be the most important consideration, provided the patient can receive a dose necessary to retain stability, and the LAI should be chosen accordingly. Deltoid injections may be able to be administered with reduced contact, or on a “drive-up” basis.¹⁰ Consider transitioning a patient who is receiving olanzapine pamoate to an alternate LAI or oral formulation, because the 3-hour observation period that is required after olanzapine pamoate administration is particularly problematic. While it may not be ideal to make medication changes during a pandemic, it is worth carefully weighing the patient’s stability and historical experience with other LAIs to determine if a safer/longer-spaced option is worth trying.¹¹

We recommend only switching among similar antipsychotics (ie, risperidone to paliperidone), or between different preparations of the same drug (ie, Abilify Maintena to Aristada), if possible, as these are the lowest risk transitions with regards to relapse. Table 3 provides examples.

When should the LAI be administered?

The pharmacokinetics of LAIs allow for some flexibility in terms of when an LAI needs to be administered. The package inserts of all second-generation LAIs include missed-dose guidelines. These guidelines provide information on how long one can wait before the next injection is due, and what additional measures must be taken when beyond that date. Delaying an injection may be prudent, and the missed dose guidelines will indicate when one must consider supplementing with oral medications. For patients who are in quarantine, it may be better to delay an injection until the patient ends their quarantine than to deliver the dose during quarantine. Administering an injection earlier also is usually safe; off-cycle visits may help minimize patient contact (ie, if the patient happens to be coming into the vicinity of the clinic, or requires phlebotomy for therapeutic drug monitoring), and assist in planning for possible resurgences. When appropriate, and after considering the risk of worsening adverse effects, administering a higher dose than the usual maintenance dose would provide a buffer if the next injection was to be delayed. Therapeutic drug monitoring can help to optimize dosing and avoid low plasma drug levels, which may be not be sufficient, particularly during this time of stress.¹² To provide optimal protection against relapse, consider administering a dose that puts patients at the higher range of plasma drug levels.

Where can the LAI be administered, and who can give it?

For patients who usually travel to a clinic, consider arranging for a more local injection (ie, at the patient’s primary care clinic in their hometown, or at a local mental health center), and explore if the patient may be able to receive their injection in their home through a visiting nurse association (VNA). In many states (approximately 30 currently), clinicians at pharmacies are also able to administer patient injections. Clinics would do well to at least plan for alternate staffing models in the event of staff illness. A pool of individuals should be available to give injections; consider training additional staff members (including MDs who may have never previously administered an LAI but could be quickly instructed to do so) to administer LAIs. Theoretically, during a public health emergency, family members, particularly those who have a background in health care, could be trained to give an injection and provided education on LAI storage and post-injection monitoring. This approach would not be consistent with FDA labeling, however, and should only be considered as a last resort.

What safety measures can be put in place?

Face-to-face time for injection administration should be kept as brief as possible. Before the encounter, obtain the patient’s clinical information, ideally through telehealth or from an acceptable distance. Medication should be drawn ahead of time, and not in an enclosed space with the patient present. Strongly consider abandoning the traditional enclosed room for the injection, and instead use larger spaces, doorways, or outside, if feasible. As previously noted, some clinics and clinicians have used a drive-up approach for LAI administration, particularly for deltoid injections.¹⁰ Individuals who administer the injections should wear personal protective equipment, and the clinic should obtain an adequate supply of this equipment well in advance.

Lessons learned at our clinic

In our community mental health center clinic, planning around these questions has allowed us to provide safe and continuous psychiatric care with LAIs during this public health emergency while reducing the risk of infection. We have worked to transfer LAI administration to VNAs and transition patients to longer-lasting formulations or oral medications where appropriate, which has resulted in an approximately 50% decrease in in-person visits. Reducing the number of in-person visits does not need to result in less frequent clinical follow-up. Telepsychiatry visits can make up for lost in-person visits and have generally been well accepted.

As we are preparing for the next phase, routine medical health monitoring (eg, metabolic monitoring, monitoring for tardive dyskinesia) that has not been at the forefront of concerns should be carefully reintroduced. Challenges encountered have included difficulty in having VNA accept patients for short-term LAI visits, changes to where on the body the injection is delivered, and patients with SMI and their families being reluctant to depart from previous routines and administration schedules.

There is great value in the collective lessons learned during this public health emergency (eg, the need for a flexible, population health-based approach; acceptability of combination telehealth and in-person visits) that can lead to more person-centered and accessible care for patients with SMI.

Bottom Line

When caring for a patient with a psychotic illness during the coronavirus disease 2019 (COVID-19) pandemic, evaluate whether it is necessary to continue a longacting injectable antipsychotic (LAI). If yes, reconsider which LAI should be administered, when and where it should be given, and by whom. Implement safety measures to minimize the risk of COVID-19 exposure and transmission.
