Antibody levels may wane after 7 months for people who got the Pfizer-BioNTech vaccine, according to a new study published on the bioRxiv preprint server.

In the study, which hasn’t yet been peer-reviewed or formally published in a medical journal, researchers analyzed blood samples from 46 healthy young or middle-aged adults after receiving two doses, and then 6 months after the second dose.

“Our study shows vaccination with the Pfizer-BioNTech vaccine induces high levels of neutralizing antibodies against the original vaccine strain, but these levels drop by nearly 10-fold by 7 months,” the researchers told Reuters.

In about half of the adults, neutralizing antibodies were undetectable at 6 months after the second dose, particularly against coronavirus variants such as Delta, Beta, and Mu.

Neutralizing antibodies only make up part of the body’s immune defense against the virus, Reuters noted, but they are still “critically important” in protecting against coronavirus infections.

“These findings suggest that administering a booster dose at around 6 to 7 months following the initial immunization will likely enhance protection,” the study authors wrote.

BioNTech said a new vaccine formula will likely be needed by mid-2022 to protect against future mutations of the virus, according to the Financial Times.

“This year, [a different vaccine] is completely unneeded, but by mid-next year, it could be a different situation,” Ugur Sahin, MD, cofounder and CEO of BioNTech, told the news outlet.

Current variants, namely the Delta variant, are more contagious than the original coronavirus strain but not different enough to evade current vaccines, he said. But new strains may be able to evade boosters.

“This virus will stay, and the virus will further adapt,” Dr. Sahin said. “This is a continuous evolution, and that evolution has just started.”

A one-time dose of two long-acting monoclonal antibodies reduced the risk of developing symptomatic COVID by 77% in comparison with placebo (P < .001) in a randomized, double-blind, placebo-controlled, phase 3 trial in adults, according to researchers who presented results at IDWeek 2021, an annual scientific meeting on infectious diseases.

The mix of tixagevimab and cilgavimab (AZD7442, Astra Zeneca) in a 300-mg dose is delivered in two intramuscular injections.

“This is the first long-acting combination of monoclonal antibodies that represents a potential new option to augment COVID-19 prevention,” said lead author Myron J. Levin, MD, a professor and pediatric infectious disease specialist at the University of Colorado at Denver, Aurora, who presented the findings of the PROVENT trial.

Both antibodies were taken from B cells donated by patients who had been infected with SARS-CoV-2, and they work synergistically, Dr. Levin said.

“The combination of them is better than adding results of each individually,” he said. “In vitro experiments have already shown that variants of interest and concern, including the Delta variant, are successfully neutralized by this cocktail.”

The trial was conducted in 87 sites in the United States, the United Kingdom, Spain, France, and Belgium. Participants included 5,197 unvaccinated adults who had never been infected with SARS-CoV-2 and either were at higher risk for inadequate response to COVID-19 vaccines because they were immunocompromised or were at high risk for exposure.

“Efficacy was observed through at least 3 months,” Dr. Levin said. “Preliminary pharmacokinetic modeling predicts potential protection for up to 12 months.”

Raymund Razonable, MD, an infectious disease expert with the Mayo Clinic in Rochester, Minn., who was not involved with the trial, told this news organization he was particularly interested in this combination because the developers made use of novel technology that extends the half-life of the antibodies and because of the large number of participants in the study.

Modeling that shows protection could last up to a year is novel and important, he said.

“People won’t need frequent injections,” Dr. Razonable said. With postexposure prophylaxis monoclonal cocktails, people may be given a dose a month, he noted.

Dr. Razonable said, “This is something intended to prevent COVID in people who are unvaccinated. The downside to that is we want people to get vaccinated. The best strategy so far is really vaccination.”

He said AZD7442 could potentially help fill the void for patients who are not able to respond to the COVID vaccines, including some who are immunocompromised or are undergoing chemotherapy.

Dr. Razonable said that, although the 77% reduction for developing symptomatic COVID-19 (95% confidence interval vs. placebo, 46.0-90.0; P < .001) is impressive, it is a reduction in relative risk. Still unknown is how much an individual’s absolute risk is reduced.

He also said it would be helpful to know how many people in the study population were immunocompromised, “because I think that’s where this product will be useful for prevention.”

The primary study endpoints were the first case of SARS-CoV-2 RT-PCR-positive symptomatic illness post dose and prior to day 183 (efficacy) as well as the safety of the product.

The cocktail appeared to be well tolerated. Adverse events occurred in 35% of participants administered AZD7442 and in 34% of the placebo group. Injection-site reactions occurred in 2.4% of the AZD7442 group and in 2.1% of the placebo group. There was one case of severe or critical COVID-19; two COVID-19–related deaths occurred in the placebo group.

AZD7442 is being developed with the help of funding from the U.S. government. Dr. Levin has received support from GlaxoSmithKline companies. Many of the coauthors are employed by AstraZeneca and hold stock in the company. Dr. Razonable has disclosed no relevant financial relationships.

The U.S. Department of Veteran Affairs (VA) has been unable to provide genetic counseling to veterans at the same level as the civilian community, and other gaps exist, a genetic counselor told oncologist and hematologist colleagues. The good news is that telemedicine is turning out to be a valuable and proven way to reach veterans who need this kind of care, she said, although certain patients are being left behind.

“To me, telehealth is no doubt the way to go. But it is really important that we continue to look into these disparities, what's causing them, and how we can find a path forward,” said

Deborah Hartzfeld, MS, CGC, of the Genomic Medicine Service based in Salt Lake City, Utah. She spoke in a presentation at the 2021 annual meeting of the Association of VA Hematology/Oncology (AVAHO) that was held virtually and in person in Denver, Colorado, from September 24 to September 26, 2021.

As Harzfeld explained, the genetic counselor workforce is expanding along with the number of indications for genetic testing, especially in cancer, “where the need for germline genetic testing for inherited cancer genes becomes broader every year.”

Genetic counselors are a homogenous group, she said, as revealed by a 2021 survey of most of the nation’s 5,629 certified generic counselors. The North American survey, by the National Society of Genetic Counselors, found that 94% of respondents identified themselves as female, and 90% were white/non-Hispanic.  

The survey report also noted that “the genetic counseling profession has grown by over 100% in the last 10 years and is expected to grow another 100% over the next 10 years. By 2025 there should be nearly 7,500 certified genetic counselors, and by 2030 there are likely to be over 10,000.”

Genetic counseling within the VA has also grown rapidly. In 2010, Harzfeld said, about 737 veterans were referred for the service. In 2020, the number was about 10,000, with about half referred for personal or family history of cancer.

The VA has 18 genetic counselors, not all of whom are actively seeing patients or working full time, she said. “Per the National Society of Genetic Counselors, there's one clinical genetic counselor per 100,000 people in the general population,” she said. “It's one for about 474,000 in the VA.”

Wait times for genetic counseling within the VA exceed Mission Act standards outside of urgent referrals in matters such as surgical or medical management, she said. “We usually see those patients within a week, but other folks have to wait or are referred into the community. It remains unclear how many of our patients could access care easily in the community or what the wait times at any individual VA will be.”

Fortunately, she said, telemedicine has increased access to genetic counseling within the general population and the VA, Harzfeld said. “A recent systematic evidence review found providing genetic counseling via video or telephone is comparable to in-person care, it increases access and it's likely feasible and acceptable to major stakeholders. It's worth noting that the data in this evidence review was collected prior to COVID-19 when fewer programs were using telehealth.”

Genetic counseling works especially well via telehealth because counselors don’t perform physical examinations, she said. “Prior to COVID, service probably saw maybe 4 VVC [VA Video Connect] appointments per month for genetic counseling. Now, VVC makes up about 70% of our new patient encounters. About 25% are telephone and about 5% are clinical video telehealth where the veteran goes into their clinic to be seated in front of the machine.”

Research has suggested that non-White patients are 40 to 50% less likely to be referred to telehealth for genetic counseling vs. in-person encounters, she said, although women in general (including black women) are more likely to be referred.

Harzfeld highlighted several challenges facing genetic counseling in the VA. She notes that contracted laboratories aren’t “really set up to be experts in germline genetic testing, so they’re not as nimble, and their test catalogs are not most likely going to be as comprehensive enough for what is needed.” Also, she said, “test ordering can be quite burdensome.”

“We need to continue working with various partners to increase access and the ease of ordering genetic testing,” she said.

A monoclonal antibody combination of casirivimab and imdevimab (REGEN-COV) significantly reduced the risk of COVID-19–related hospitalizations and death from any cause in the phase 3 portion of an adaptive trial of outpatients.

Researchers, led by David Weinreich, MD, MBA, executive vice president of the drug cocktail’s manufacturer Regeneron, found in the randomized trial that the combination also resolved symptoms and reduced the SARS-CoV-2 viral load more quickly, compared with placebo.

Findings were published in the New England Journal of Medicine. 

COVID-related hospitalization or death from any cause occurred in 18 of 1,355 patients (1.3%) in the group getting 2,400 mg infusions of the study drug, compared with 62 (4.6%) of 1,341 in the matching placebo group, indicating a relative risk reduction of 71.3%; P < .001.

Sunil Joshi, MD, president of the Duval County Medical Society Foundation and an immunologist in Jacksonville, Fla., said in an interview that these findings confirm benefits of REGEN-COV and are very good news for a patient group that includes those age 65 and older with high blood pressure, diabetes, or obesity; and for people not vaccinated, who are all at high risk of hospitalization or death if they get COVID-19.

“Vaccines are critically important,” he said, “but if you were to be infected and know that there’s a way to keep yourself out of the hospital, this is very good news.”
 

Researchers seek lowest doses

This trial found that the effect was similar when researchers cut the doses in half. These outcomes occurred in 7 of 736 (1%) of patients given 1,200 mg of REGEN-COV and in 24 (3.2%) of 748 in the matching placebo group (relative risk reduction, 70.4%; P = .002).

Symptoms were resolved on average 4 days earlier with each REGEN-COV dose than with placebo (10 days vs. 14 days; P < .001 for both comparisons).

Dr. Weinreich said in an interview that trials will continue to find the lowest effective doses that can stand up to all evolving variants.

“This is one of those settings where you don’t want to underdose. You’ve got one shot at this,” he said. “We’d love to do lower doses. It would be more convenient and we could treat more patients, but if it generates more clinical failures or doesn’t work with certain variants, then you’ve done a huge disservice to the world.”

Also new in this study is that researchers tested not only seronegative patients, but patients at high risk regardless of blood antibody status, he said.

“It’s the first suggestion of data that if you’re breaking through a vaccine and you’re at high risk, the use of the cocktail is something to strongly consider because treatment early is better than treatment later,” Dr. Weinreich said.

In addition to efficacy, the phase 3 trial demonstrated the cocktail had a good safety profile. Serious adverse events occurred more often in the placebo group (4%) than in the 1,200-mg group (1.1%) and the 2,400-mg group (1.3%). Infusion reactions (grade 2 or higher) occurred in less than 0.3% of patients in all groups. 

William Fales, MD, state medical director for the Michigan Department of Health and Human Services, said the results confirm the promise of REGEN-COV for reducing hospitalizations and death in a peer-reviewed publication.
 

COVID-19 a moving target

However, Dr. Fales noted that COVID-19 is a moving target with emerging variants. The criteria for populations at high risk have also broadened since the start of the study, he said.

“A great example is pregnancy is now included as high risk, and that would have likely been a specific contraindication of patients in this clinical trial,” he said.

Dr. Fales said Michigan has been using both REGEN-COV and the Eli Lilly combination of bamlanivimab and etesevimab, which also has an emergency use authorization (EUA) from the Food and Drug Administration, with positive results.

REGEN-COV has an EUA to treat people who are at high risk of serious consequences from COVID-19, including those who are already infected (nonhospitalized) or those in certain postexposure prophylaxis settings.

“We’re seeing very low hospitalization rates and few deaths in a state that is predominately Delta,” Dr. Fales said. “So, this makes us feel that we’re doing the right thing and supports the current efforts around the country to make monoclonal antibody therapy available to high-risk patients.”  

Dr. Joshi noted that trial results have been emerging from other monoclonal antibody cocktails with different COVID-19 patient groups.

However, he said in an interview, “how much more effective they would be than this is something we’d have to look at, as 71% effectiveness in keeping people out of the hospital is pretty good for any treatment.”

“These are great numbers, but vaccination itself keeps you from getting the disease in the first place and not just for a short time period. This treatment is just that – a treatment. It gets you through that episode but it doesn’t mean you won’t get sick again. You don’t develop an immune response as you do with the vaccine,” he said.

Dr. Weinreich agreed: “This is not a substitute for a vaccine except for the small group who get the vaccine and their bodies can’t respond to it because they’re significantly immunocompromised.”

The results from this paper “are one piece of a large, multistudy, phase 3 program that basically spans from prophylaxis all the way to hospitalization and pretty much the gamut – all of them – have worked. All of these studies have shown dramatic improvement in whatever the definitive regulatory endpoint is,” Dr. Weinreich said.

He said discussions are ongoing for full regulatory approval in the United States and for expanding the EUA for other populations, including pre-exposure prophylaxis, “which the [United Kingdom’s] authority has already granted us but the FDA has not.”

A monoclonal antibody combination of casirivimab and imdevimab (REGEN-COV) significantly reduced the risk of COVID-19–related hospitalizations and death from any cause in the phase 3 portion of an adaptive trial of outpatients.

Researchers, led by David Weinreich, MD, MBA, executive vice president of the drug cocktail’s manufacturer Regeneron, found in the randomized trial that the combination also resolved symptoms and reduced the SARS-CoV-2 viral load more quickly, compared with placebo.

Findings were published in the New England Journal of Medicine. 

COVID-related hospitalization or death from any cause occurred in 18 of 1,355 patients (1.3%) in the group getting 2,400 mg infusions of the study drug, compared with 62 (4.6%) of 1,341 in the matching placebo group, indicating a relative risk reduction of 71.3%; P < .001.

Sunil Joshi, MD, president of the Duval County Medical Society Foundation and an immunologist in Jacksonville, Fla., said in an interview that these findings confirm benefits of REGEN-COV and are very good news for a patient group that includes those age 65 and older with high blood pressure, diabetes, or obesity; and for people not vaccinated, who are all at high risk of hospitalization or death if they get COVID-19.

“Vaccines are critically important,” he said, “but if you were to be infected and know that there’s a way to keep yourself out of the hospital, this is very good news.”
 

Researchers seek lowest doses

This trial found that the effect was similar when researchers cut the doses in half. These outcomes occurred in 7 of 736 (1%) of patients given 1,200 mg of REGEN-COV and in 24 (3.2%) of 748 in the matching placebo group (relative risk reduction, 70.4%; P = .002).

Symptoms were resolved on average 4 days earlier with each REGEN-COV dose than with placebo (10 days vs. 14 days; P < .001 for both comparisons).

Dr. Weinreich said in an interview that trials will continue to find the lowest effective doses that can stand up to all evolving variants.

“This is one of those settings where you don’t want to underdose. You’ve got one shot at this,” he said. “We’d love to do lower doses. It would be more convenient and we could treat more patients, but if it generates more clinical failures or doesn’t work with certain variants, then you’ve done a huge disservice to the world.”

Also new in this study is that researchers tested not only seronegative patients, but patients at high risk regardless of blood antibody status, he said.

“It’s the first suggestion of data that if you’re breaking through a vaccine and you’re at high risk, the use of the cocktail is something to strongly consider because treatment early is better than treatment later,” Dr. Weinreich said.

In addition to efficacy, the phase 3 trial demonstrated the cocktail had a good safety profile. Serious adverse events occurred more often in the placebo group (4%) than in the 1,200-mg group (1.1%) and the 2,400-mg group (1.3%). Infusion reactions (grade 2 or higher) occurred in less than 0.3% of patients in all groups. 

William Fales, MD, state medical director for the Michigan Department of Health and Human Services, said the results confirm the promise of REGEN-COV for reducing hospitalizations and death in a peer-reviewed publication.
 

COVID-19 a moving target

However, Dr. Fales noted that COVID-19 is a moving target with emerging variants. The criteria for populations at high risk have also broadened since the start of the study, he said.

“A great example is pregnancy is now included as high risk, and that would have likely been a specific contraindication of patients in this clinical trial,” he said.

Dr. Fales said Michigan has been using both REGEN-COV and the Eli Lilly combination of bamlanivimab and etesevimab, which also has an emergency use authorization (EUA) from the Food and Drug Administration, with positive results.

Adherence to the MIND diet can improve memory and thinking skills of older adults, even in the presence of Alzheimer’s disease pathology, new data from the Rush Memory and Aging Project (MAP) show.

Suprijono Suharjoto/Fotolia

“The MIND diet was associated with better cognitive functions independently of brain pathologies related to Alzheimer’s disease, suggesting that diet may contribute to cognitive resilience, which ultimately indicates that it is never too late for dementia prevention,” lead author Klodian Dhana, MD, PhD, with the Rush Institute of Healthy Aging at Rush University, Chicago, said in an interview.

The study was published online Sept. 14, 2021, in the Journal of Alzheimer’s Disease.
 

Impact on brain pathology

“While previous investigations determined that the MIND diet is associated with a slower cognitive decline, the current study furthered the diet and brain health evidence by assessing the impact of brain pathology in the diet-cognition relationship,” Dr. Dhana said.

The MIND diet was pioneered by the late Martha Clare Morris, ScD, a Rush nutritional epidemiologist, who died in 2020 of cancer at age 64. A hybrid of the Mediterranean and DASH (Dietary Approaches to Stop Hypertension) diets, the MIND diet includes green leafy vegetables, fish, nuts, berries, beans, and whole grains and limits consumption of fried and fast foods, sweets, and pastries.

The current study focused on 569 older adults who died while participating in the MAP study, which began in 1997. Participants in the study were mostly White and were without known dementia. All of the participants agreed to undergo annual clinical evaluations. They also agreed to undergo brain autopsy after death.

Beginning in 2004, participants completed annual food frequency questionnaires, which were used to calculate a MIND diet score based on how often the participants ate specific foods.

The researchers used a series of regression analyses to examine associations of the MIND diet, dementia-related brain pathologies, and global cognition near the time of death. Analyses were adjusted for age, sex, education, apo E4, late-life cognitive activities, and total energy intake.

The results show that a higher MIND diet score was associated with better global cognitive functioning around the time of death (beta, 0.119; P = .003).

Notably, the researchers said, neither the strength nor the significance of association changed markedly when AD pathology and other brain pathologies were included in the model (beta, 0.111; P = .003).

The relationship between better adherence to the MIND diet and better cognition remained significant when the analysis was restricted to individuals without mild cognitive impairment at baseline (beta, 0.121; P = .005) as well as to persons in whom a postmortem diagnosis of AD was made on the basis of NIA-Reagan consensus recommendations (beta, 0.114; P = .023).

The limitations of the study include the reliance on self-reported diet information and a sample made up of mostly White volunteers who agreed to annual evaluations and postmortem organ donation, thus limiting generalizability.

Strengths of the study include the prospective design with annual assessment of cognitive function using standardized tests and collection of the dietary information using validated questionnaires. Also, the neuropathologic evaluations were performed by examiners blinded to clinical data.

“Diet changes can impact cognitive functioning and risk of dementia, for better or worse. There are fairly simple diet and lifestyle changes a person could make that may help to slow cognitive decline with aging and contribute to brain health,” Dr. Dhana said in a news release.
 

Builds resilience

Weighing in on the study, Heather Snyder, PhD, vice president of medical and scientific relations for the Alzheimer’s Association, said this “interesting study sheds light on the impact of nutrition on cognitive function.

“The findings add to the growing literature that lifestyle factors – like access to a heart-healthy diet – may help the brain be more resilient to disease-specific changes,” Snyder said in an interview.

“The Alzheimer’s Association’s US POINTER study is investigating how lifestyle interventions, including nutrition guidance, like the MIND diet, may impact a person’s risk of cognitive decline. An ancillary study of the US POINTER will include brain imaging to investigate how these lifestyle interventions impact the biology of the brain,” Dr. Snyder noted.

The research was supported by the National Institute on Aging of the National Institutes of Health. Dr. Dhana and Dr. Snyder disclosed no relevant financial relationships.

A new series of cases of cerebral venous sinus thrombosis (CVST) linked to the adenoviral vector COVID-19 vaccines has been reported, confirming the severity of the reaction and the associated high mortality rate.

The new series comes from an international registry of consecutive patients who experienced CVST within 28 days of COVID-19 vaccination between March 29 and June 18, 2021, from 81 hospitals in 19 countries.

The cases are described in an article published online on Sept. 28. in JAMA Neurology.

“This is a reliable description on the clinical condition of these patients with CVST associated with COVID-19 vaccination. It is striking that this a much worse condition than CVST not associated with COVID-19 vaccination, with a much higher rate of intracerebral hemorrhage and coma and a much higher mortality rate,” senior author Jonathan M. Coutinho, MD, Amsterdam University Medical Centers, told this news organization.

These data confirm the observations from an earlier U.K. cohort in which cases of cerebral venous thrombosis linked to COVID-19 vaccination occurred.

“This is the biggest series, and as an international series, it gives a broader perspective from a larger range of countries,” Dr. Coutinho said. “All the data together show that, although this side effect is rare, the consequences are very severe,” he added.

In the current study, the researchers regarded CVST as being linked to the vaccine if it was accompanied by thrombosis with thrombocytopenia syndrome (TTS), as evidenced by thrombosis and new-onset thrombocytopenia.

In the cohort of 116 patients with CVST after COVID-19 vaccination, 78 (67.2%) had thrombosis with TTS and were thus classified as having had a vaccine-related adverse event. These patients were frequently comatose at presentation (24%) and often had intracerebral hemorrhage (68%) and concomitant thromboembolism (36%); 47% died during hospitalization.

These patients were compared with the 38 patients in the same cohort who had CVST but in whom there was no indication of concomitant thrombosis and thrombocytopenia. The case patients were also compared with a control group of 207 patients with CVST who were included in a separate international registry before the COVID-19 pandemic.

Mortality rates were much higher among the patients deemed to have had a vaccine-related CVST. The in-hospital mortality rate was 47%, compared with 5% among the patients in the same cohort who did not have TTS and 3.9% among the prepandemic control group.

The mortality rate was even higher (61%) among patients in the TTS group for whom the diagnosis was made before the condition garnered attention in the scientific community. The mortality rate was 42% among patients diagnosed later.

Of the 78 patients in whom CVST and TTS occurred after COVID-19 vaccination in this cohort, 76 had received the AstraZeneca vaccine (in 75 patients, CVST and TTS occurred after the first vaccination; in one patient, they occurred after the second vaccination). One patient had received the Johnson & Johnson vaccine, and one had received the Pfizer vaccine.

“After more analysis, the case after the Pfizer vaccination is not believed to be caused by the vaccine,” Dr. Coutinho said. “In that case, the patient had a platelet count just below the lower limit and was taking an immunomodulator drug that is known to be associated with thrombocytopenia.”

For two patients who received the AstraZeneca vaccine, there was also an alternative explanation for the thrombocytopenia.

Dr. Coutinho also pointed out that the Johnson & Johnson vaccine has been used mainly in the United States, and these data were largely from other countries.

The median time from vaccination to CVST symptom onset was 9 days in the TTS group. The median platelet count at hospital admission among patients with postvaccination CVST-TTS was 45. Three patients presented with a normal platelet count and developed thrombocytopenia during admission; two patients presented with mild thrombocytopenia, 30 presented with moderate thrombocytopenia, and 43 presented with severe thrombocytopenia.

Antibodies against platelet factor 4 (PF4) were measured in 69 patients with TTS, of whom 63 (91%) tested positive (the one patient in whom TTS occurred after the patient received the Pfizer vaccine did not test positive). However, the researchers note that sensitivity varies among different PF4 ELISA tests. Findings of platelet activation assays were positive in all 36 tested patients.

In the TTS group, 52 patients (67%) received immunomodulation therapy, most often intravenous immunoglobulins (IVIG). Among patients treated with IVIG, the mortality rate was lower (28%).
 

Different from CVST linked to natural COVID-19 infection

Dr. Coutinho noted that CVST can occur in natural SARS-CoV-2 infection but that vaccine-associated CVST is very different.

“In natural COVID-19 infection, there is an increased risk of thrombosis, and some patients can get CVST as a part of this, but in these cases, this is not accompanied by thrombocytopenia. While the CVST in natural COVID-19 infection is also associated with a bad prognosis, this is more to do with the underlying disease. It is normally the very sick COVID patients who develop CVST, and these patients usually die from the underlying disease rather than the CVST itself,” he explained.

“Clinicians need to be aware of vaccine-related CVST, as it requires very specific and rapid treatment,” Dr. Coutinho stressed.

“Patients presenting with an extremely severe headache (unlike any headache they’ve had before) or with seizures or a focal deficit (weakness in arm or problems with speaking or vision) within 4 weeks of an adenovirus COVID-19 vaccination should ring alarm bells. It is important to do diagnostics quickly, with a platelet count the most important first step, and a rapid CT/MRI scan,” he said.

Other tests that should be conducted are D-dimer for thrombosis and the PF4 antibody test. But results for the PF4 antibody test can take days to come back, and clinicians shouldn’t wait for that, Dr. Coutinho notes.

“Specific treatment needs to be given immediately – with anticoagulation (preferably nonheparin) and immunomodulation with IVIG to stop the immune reaction. Platelets should not be given – that may seem counterintuitive in patients with a low platelet count, but giving platelets makes it worse,” he said.
 

Is there a geographic difference?

Dr. Coutinho pointed out that fewer cases of this vaccine-related CVST are being reported at the current time.

“We are not sure why this is the case. These adenovirus vaccines are not being used much now in Western countries, but our collaboration covers many less developed countries in South America and Asia, which are relying heavily on these vaccines. We are now shifting focus to these countries, but so far we have only seen a handful of cases from these areas,” he said.

He suggested that this may be because these countries started their vaccination programs later and are vaccinating their elderly (who are not so susceptible to this side effect) first, or it may be because of some environmental or genetic factor that has not yet been discovered.

“This is now an important research question – is the risk of vaccine-induced CVST the same in different countries or ethnicities? This could influence decisions on future vaccine strategies,” Dr. Coutinho said.

“So far, female sex is the strongest risk factor for vaccine-induced CVST. In our cohort, 81% of cases were in women. In addition, 95% were White, but that doesn’t allow us to conclude that this is a risk factor, as the majority of people who have been vaccinated are White. So, we have no clear insight into that yet,” he said.

In a comment for this news organization, the lead author of the previous U.K. report of a series of 70 cases of cerebral venous thrombosis linked to COVID-19 vaccination, Richard Perry, PhD, University College Hospital, London, described this new report as “an excellent study, with many of the same strengths and weaknesses as our study and has very similar results.”

Dr. Perry noted that the two studies used slightly different definitions of vaccine-induced thrombotic thrombocytopenia, but the cases reported appear to be very similar overall. “It is reassuring and gratifying to see that they have made such similar observations,” he said.

“And as they have drawn their cases from a broad range of countries whereas ours were all from the U.K., this provides evidence that the observations from both studies are reasonably generalizable,” he added.

Dr. Perry pointed out that this new report states that TTS occurred in one patient after the patient had received a second dose of the AstraZeneca vaccine. “I would like to know more about this case, because we didn’t see any cases after a second dose in our cohort,” he said.

Dr. Coutinho responded that he didn’t believe this was the first reported case after the second dose.

The study did not receive any specific funding. Dr. Coutinho has received grants paid to his institution from Boehringer Ingelheim and Bayer and payments paid to his institution for data safety monitoring board participation by Bayer.

A new series of cases of cerebral venous sinus thrombosis (CVST) linked to the adenoviral vector COVID-19 vaccines has been reported, confirming the severity of the reaction and the associated high mortality rate.

The new series comes from an international registry of consecutive patients who experienced CVST within 28 days of COVID-19 vaccination between March 29 and June 18, 2021, from 81 hospitals in 19 countries.

The cases are described in an article published online on Sept. 28. in JAMA Neurology.

“This is a reliable description on the clinical condition of these patients with CVST associated with COVID-19 vaccination. It is striking that this a much worse condition than CVST not associated with COVID-19 vaccination, with a much higher rate of intracerebral hemorrhage and coma and a much higher mortality rate,” senior author Jonathan M. Coutinho, MD, Amsterdam University Medical Centers, told this news organization.

These data confirm the observations from an earlier U.K. cohort in which cases of cerebral venous thrombosis linked to COVID-19 vaccination occurred.

“This is the biggest series, and as an international series, it gives a broader perspective from a larger range of countries,” Dr. Coutinho said. “All the data together show that, although this side effect is rare, the consequences are very severe,” he added.

In the current study, the researchers regarded CVST as being linked to the vaccine if it was accompanied by thrombosis with thrombocytopenia syndrome (TTS), as evidenced by thrombosis and new-onset thrombocytopenia.

In the cohort of 116 patients with CVST after COVID-19 vaccination, 78 (67.2%) had thrombosis with TTS and were thus classified as having had a vaccine-related adverse event. These patients were frequently comatose at presentation (24%) and often had intracerebral hemorrhage (68%) and concomitant thromboembolism (36%); 47% died during hospitalization.

These patients were compared with the 38 patients in the same cohort who had CVST but in whom there was no indication of concomitant thrombosis and thrombocytopenia. The case patients were also compared with a control group of 207 patients with CVST who were included in a separate international registry before the COVID-19 pandemic.

Mortality rates were much higher among the patients deemed to have had a vaccine-related CVST. The in-hospital mortality rate was 47%, compared with 5% among the patients in the same cohort who did not have TTS and 3.9% among the prepandemic control group.

The mortality rate was even higher (61%) among patients in the TTS group for whom the diagnosis was made before the condition garnered attention in the scientific community. The mortality rate was 42% among patients diagnosed later.

Of the 78 patients in whom CVST and TTS occurred after COVID-19 vaccination in this cohort, 76 had received the AstraZeneca vaccine (in 75 patients, CVST and TTS occurred after the first vaccination; in one patient, they occurred after the second vaccination). One patient had received the Johnson & Johnson vaccine, and one had received the Pfizer vaccine.

“After more analysis, the case after the Pfizer vaccination is not believed to be caused by the vaccine,” Dr. Coutinho said. “In that case, the patient had a platelet count just below the lower limit and was taking an immunomodulator drug that is known to be associated with thrombocytopenia.”

For two patients who received the AstraZeneca vaccine, there was also an alternative explanation for the thrombocytopenia.

Dr. Coutinho also pointed out that the Johnson & Johnson vaccine has been used mainly in the United States, and these data were largely from other countries.

The median time from vaccination to CVST symptom onset was 9 days in the TTS group. The median platelet count at hospital admission among patients with postvaccination CVST-TTS was 45. Three patients presented with a normal platelet count and developed thrombocytopenia during admission; two patients presented with mild thrombocytopenia, 30 presented with moderate thrombocytopenia, and 43 presented with severe thrombocytopenia.

Antibodies against platelet factor 4 (PF4) were measured in 69 patients with TTS, of whom 63 (91%) tested positive (the one patient in whom TTS occurred after the patient received the Pfizer vaccine did not test positive). However, the researchers note that sensitivity varies among different PF4 ELISA tests. Findings of platelet activation assays were positive in all 36 tested patients.

In the TTS group, 52 patients (67%) received immunomodulation therapy, most often intravenous immunoglobulins (IVIG). Among patients treated with IVIG, the mortality rate was lower (28%).
 

Different from CVST linked to natural COVID-19 infection

Dr. Coutinho noted that CVST can occur in natural SARS-CoV-2 infection but that vaccine-associated CVST is very different.

“In natural COVID-19 infection, there is an increased risk of thrombosis, and some patients can get CVST as a part of this, but in these cases, this is not accompanied by thrombocytopenia. While the CVST in natural COVID-19 infection is also associated with a bad prognosis, this is more to do with the underlying disease. It is normally the very sick COVID patients who develop CVST, and these patients usually die from the underlying disease rather than the CVST itself,” he explained.

“Clinicians need to be aware of vaccine-related CVST, as it requires very specific and rapid treatment,” Dr. Coutinho stressed.

“Patients presenting with an extremely severe headache (unlike any headache they’ve had before) or with seizures or a focal deficit (weakness in arm or problems with speaking or vision) within 4 weeks of an adenovirus COVID-19 vaccination should ring alarm bells. It is important to do diagnostics quickly, with a platelet count the most important first step, and a rapid CT/MRI scan,” he said.

Other tests that should be conducted are D-dimer for thrombosis and the PF4 antibody test. But results for the PF4 antibody test can take days to come back, and clinicians shouldn’t wait for that, Dr. Coutinho notes.

“Specific treatment needs to be given immediately – with anticoagulation (preferably nonheparin) and immunomodulation with IVIG to stop the immune reaction. Platelets should not be given – that may seem counterintuitive in patients with a low platelet count, but giving platelets makes it worse,” he said.
 

Is there a geographic difference?

Dr. Coutinho pointed out that fewer cases of this vaccine-related CVST are being reported at the current time.

“We are not sure why this is the case. These adenovirus vaccines are not being used much now in Western countries, but our collaboration covers many less developed countries in South America and Asia, which are relying heavily on these vaccines. We are now shifting focus to these countries, but so far we have only seen a handful of cases from these areas,” he said.

He suggested that this may be because these countries started their vaccination programs later and are vaccinating their elderly (who are not so susceptible to this side effect) first, or it may be because of some environmental or genetic factor that has not yet been discovered.

“This is now an important research question – is the risk of vaccine-induced CVST the same in different countries or ethnicities? This could influence decisions on future vaccine strategies,” Dr. Coutinho said.

“So far, female sex is the strongest risk factor for vaccine-induced CVST. In our cohort, 81% of cases were in women. In addition, 95% were White, but that doesn’t allow us to conclude that this is a risk factor, as the majority of people who have been vaccinated are White. So, we have no clear insight into that yet,” he said.

Many people are confused — patients and healthcare providers alike — in the wake of the U.S. Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) announcements about who is authorized to get a third or ‘booster’ shot of the Pfizer/BioNTech COVID-19 vaccine.

The official word on boosters from the CDC in the early morning hours of September 24 sparked a jump in people calling about or coming in for a third shot, healthcare providers report. At the same time, the uncertainty from changing federal messages about boosters is causing some chaos, especially in the form of vaccine misinformation.

The confusion started, in part, with the August 13 announcement that immunocompromised Americans were eligible for a booster shot. Next came the initial Biden administration intention to provide most U.S. adults with a third shot starting September 20 — an announcement later rolled back — followed by the Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) limiting boosters to select groups last week.

“It was only 3% of the population that was going to be getting a third dose, then it was back to everyone being able to get the booster, and then it’s back to a select crew,” Louito Edje, MD, a family physician in private practice in Cincinnati, said in an interview with this news organization.

This kind of mixed messaging is generating more questions than answers.  

“Even though that is following the science, translating the science into policy, it’s really fraught with confusion for patients, especially,” added Dr. Edje, professor educator in the departments of medical education and family and community medicine at UC Health and a fellow of the American Academy of Family Physicians.

When asked if he’s seeing more uncertainty about boosters, community pharmacist Brian Caswell, RPh, said: “I’m going to have to say yes because I’ve been confused myself at times.”

“Yes, there is a lot of confusion,” added Mr. Caswell, owner or co-owner of four pharmacies in Kansas and Missouri and president of the National Community Pharmacists Association. 
 

Boosting misinformation?

“Unfortunately, confusion leads to an acceleration of misinformation,” Mr. Caswell said.

Dr. Edje shared an example. “The folks who have been hesitant to even get the first vaccine appear now a little less likely to want to go ahead and get vaccinated.”

These patients point to breakthrough COVID-19 cases of the Delta variant, which “reinforces that they don’t need to get vaccinated in the first place,” Dr. Edje said.

“That’s unfortunate because it’s a complete fallacy.”

Clearer communication from the federal government could help alleviate confusion, Mr. Caswell said. “I would like to see an official CDC chart that states who is eligible as of a certain date. Something that is accessible through their webpage or a social media source that can be updated. That would help all of us.”

“For myself, I’ve got patients from Kansas, Oklahoma, and Missouri that might be operating under different guidelines. That makes it even more confusing,” he said.

More clarity is needed for individuals seeking boosters as well. “It would help to be very clear with the general public, who are becoming very knowledgeable within this vaccine realm,” Mr. Caswell said.
 

‘Gaming the system’

Although most people seeking a booster shot at one of Caswell’s pharmacies are following official recommendations, there are some who remain ineligible but nonetheless come in for an additional vaccine.

“Even before this announcement last Friday, in the latter part of August when the CDC talked about a booster for immunocompromised, we had interest from people who did not meet the criteria,” Mr. Caswell said.

To the ineligible, he and his staff explain the approval process, why certain decisions are made, and point out that the number of eligible Americans is likely to expand in the future.

“The vast majority of them are understanding,” Mr. Caswell said. “But we’ve had some people who really didn’t want to accept the information, and I don’t know what they’ve done.”

“Some people are gaming the system to get their booster or second shot of J&J,” he said.

For example, Mr. Caswell had a patient who crossed over state lines from Missouri seeking a vaccine booster at Wolkar Drug, a pharmacy in Baxter Springs, Kan. “We found out later he had a J&J shot at a facility or provider in Missouri. He came over to Kansas, signed up for it and got a booster with Moderna.”

“We called and asked him if he was aware of it. He said, ‘yes.’ When we questioned him more about it, he hung up.”

Dr. Edje is likewise seeing interest from some ineligible patients, she said.
 

Crossing a liability line?

Mr. Caswell has asked for advice from lawyers and the State Board of Pharmacy on potential liability if a pharmacist gives a booster to a patient not eligible under the official FDA and CDC guidance.

“We ask patients direct questions about whether they’ve had the COVID vaccine, COVID, and a whole litany of questions they must answer. And we’re assuming they are going to be honest and forthright,” he said. “The pharmacist needs to make sure they make every effort to get that information from the patient.”

Normally, healthcare providers like Mr. Caswell report each COVID-19 vaccination to the state registry after administration. “We have not gone through a police action and checked the registry first,” he said.

But, if people continue to try ‘gaming the system,’ he said, he might have to start checking the state registry before giving someone a booster.

The American Academy of Family Physicians offers advice from the CDC about legal protections for providers.

“As outlined by CDC, any off-label use of the Comirnaty/Pfizer-BioNTech COVID-19 vaccine is not authorized at this time and may not be covered under the PREP Act or the PREP Act declaration. This means that clinicians providing the vaccine outside of the authorized/approved use may not have immunity from claims,” the AAFP website states.

“Per CDC, individuals who receive a third dose may not be eligible for compensation after a possible adverse event. Such use would be in violation of the CDC COVID-19 vaccination program provider agreement and therefore may not be reimbursable and may impact the ability of a provider to remain in the CDC program, in addition to other potential sanctions. Administration fees for off-label doses may not be reimbursed by payers.”
 

Despite confusion, demand is up

Even amid all the uncertainty, there appears to be a jump in enthusiasm for the booster shots.

“The requests have gone up quite a bit. We’ve seen a number of requests from people in person and over the phone looking to get a booster,” Mr. Caswell said. “Since the discussion at the federal level...there has been a lot of interest in the third shot booster, itself, as well as about a booster for J&J.”

“There is quite a bit of excitement out there,” he said.

Dr. Edje agreed: “I take care of a fair number of folks...including the elderly and healthcare professionals. They are already asking for the booster.”

Interestingly, Dr. Edje would like to get a booster herself but is not eligible for the Pfizer third shot. She is a participant in a Moderna vaccine trial and can only receive additional immunization as part of the study.
 

‘Walk, don’t run’

To quell any potential early rush to get a third shot, U.S. health officials are reminding booster-ineligible people that they still have some protection against COVID-19.

“If you’re a person who ultimately might get a booster that will make you optimally protected, you don’t necessarily need to get it tomorrow,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases told CNN.

CDC Director Rochelle Walensky, MD, also weighed in. She told ABC that boosters for people who received a Moderna or Johnson & Johnson vaccine will be addressed with urgency.

“I want to reiterate that this is a very slow wane. There is no urgency here to go and get your booster immediately. You know, walk don’t run to your booster appointment,” she said.

“We will come and look at the data for Moderna and J&J in very short order.”

Dr. Edje and Mr. Caswell have reported no relevant financial relationships.

“We will come and look at the data for Moderna and J&J in very short order.”

Dr. Edje and Mr. Caswell have reported no relevant financial relationships.

Many people are confused — patients and healthcare providers alike — in the wake of the U.S. Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) announcements about who is authorized to get a third or ‘booster’ shot of the Pfizer/BioNTech COVID-19 vaccine.

The official word on boosters from the CDC in the early morning hours of September 24 sparked a jump in people calling about or coming in for a third shot, healthcare providers report. At the same time, the uncertainty from changing federal messages about boosters is causing some chaos, especially in the form of vaccine misinformation.

The confusion started, in part, with the August 13 announcement that immunocompromised Americans were eligible for a booster shot. Next came the initial Biden administration intention to provide most U.S. adults with a third shot starting September 20 — an announcement later rolled back — followed by the Food and Drug Administration (FDA) and Centers for Disease Control and Prevention (CDC) limiting boosters to select groups last week.

“It was only 3% of the population that was going to be getting a third dose, then it was back to everyone being able to get the booster, and then it’s back to a select crew,” Louito Edje, MD, a family physician in private practice in Cincinnati, said in an interview with this news organization.

This kind of mixed messaging is generating more questions than answers.  

“Even though that is following the science, translating the science into policy, it’s really fraught with confusion for patients, especially,” added Dr. Edje, professor educator in the departments of medical education and family and community medicine at UC Health and a fellow of the American Academy of Family Physicians.

When asked if he’s seeing more uncertainty about boosters, community pharmacist Brian Caswell, RPh, said: “I’m going to have to say yes because I’ve been confused myself at times.”

“Yes, there is a lot of confusion,” added Mr. Caswell, owner or co-owner of four pharmacies in Kansas and Missouri and president of the National Community Pharmacists Association. 
 

Boosting misinformation?

“Unfortunately, confusion leads to an acceleration of misinformation,” Mr. Caswell said.

Dr. Edje shared an example. “The folks who have been hesitant to even get the first vaccine appear now a little less likely to want to go ahead and get vaccinated.”

These patients point to breakthrough COVID-19 cases of the Delta variant, which “reinforces that they don’t need to get vaccinated in the first place,” Dr. Edje said.

“That’s unfortunate because it’s a complete fallacy.”

Clearer communication from the federal government could help alleviate confusion, Mr. Caswell said. “I would like to see an official CDC chart that states who is eligible as of a certain date. Something that is accessible through their webpage or a social media source that can be updated. That would help all of us.”

“For myself, I’ve got patients from Kansas, Oklahoma, and Missouri that might be operating under different guidelines. That makes it even more confusing,” he said.

More clarity is needed for individuals seeking boosters as well. “It would help to be very clear with the general public, who are becoming very knowledgeable within this vaccine realm,” Mr. Caswell said.
 

‘Gaming the system’

Although most people seeking a booster shot at one of Caswell’s pharmacies are following official recommendations, there are some who remain ineligible but nonetheless come in for an additional vaccine.

“Even before this announcement last Friday, in the latter part of August when the CDC talked about a booster for immunocompromised, we had interest from people who did not meet the criteria,” Mr. Caswell said.

To the ineligible, he and his staff explain the approval process, why certain decisions are made, and point out that the number of eligible Americans is likely to expand in the future.

“The vast majority of them are understanding,” Mr. Caswell said. “But we’ve had some people who really didn’t want to accept the information, and I don’t know what they’ve done.”

“Some people are gaming the system to get their booster or second shot of J&J,” he said.

For example, Mr. Caswell had a patient who crossed over state lines from Missouri seeking a vaccine booster at Wolkar Drug, a pharmacy in Baxter Springs, Kan. “We found out later he had a J&J shot at a facility or provider in Missouri. He came over to Kansas, signed up for it and got a booster with Moderna.”

“We called and asked him if he was aware of it. He said, ‘yes.’ When we questioned him more about it, he hung up.”

Dr. Edje is likewise seeing interest from some ineligible patients, she said.
 

Crossing a liability line?

Mr. Caswell has asked for advice from lawyers and the State Board of Pharmacy on potential liability if a pharmacist gives a booster to a patient not eligible under the official FDA and CDC guidance.

“We ask patients direct questions about whether they’ve had the COVID vaccine, COVID, and a whole litany of questions they must answer. And we’re assuming they are going to be honest and forthright,” he said. “The pharmacist needs to make sure they make every effort to get that information from the patient.”

Normally, healthcare providers like Mr. Caswell report each COVID-19 vaccination to the state registry after administration. “We have not gone through a police action and checked the registry first,” he said.

But, if people continue to try ‘gaming the system,’ he said, he might have to start checking the state registry before giving someone a booster.

The American Academy of Family Physicians offers advice from the CDC about legal protections for providers.

“As outlined by CDC, any off-label use of the Comirnaty/Pfizer-BioNTech COVID-19 vaccine is not authorized at this time and may not be covered under the PREP Act or the PREP Act declaration. This means that clinicians providing the vaccine outside of the authorized/approved use may not have immunity from claims,” the AAFP website states.

“Per CDC, individuals who receive a third dose may not be eligible for compensation after a possible adverse event. Such use would be in violation of the CDC COVID-19 vaccination program provider agreement and therefore may not be reimbursable and may impact the ability of a provider to remain in the CDC program, in addition to other potential sanctions. Administration fees for off-label doses may not be reimbursed by payers.”
 

Despite confusion, demand is up

Even amid all the uncertainty, there appears to be a jump in enthusiasm for the booster shots.

“The requests have gone up quite a bit. We’ve seen a number of requests from people in person and over the phone looking to get a booster,” Mr. Caswell said. “Since the discussion at the federal level...there has been a lot of interest in the third shot booster, itself, as well as about a booster for J&J.”

“There is quite a bit of excitement out there,” he said.

Dr. Edje agreed: “I take care of a fair number of folks...including the elderly and healthcare professionals. They are already asking for the booster.”

Interestingly, Dr. Edje would like to get a booster herself but is not eligible for the Pfizer third shot. She is a participant in a Moderna vaccine trial and can only receive additional immunization as part of the study.
 

‘Walk, don’t run’

To quell any potential early rush to get a third shot, U.S. health officials are reminding booster-ineligible people that they still have some protection against COVID-19.

“If you’re a person who ultimately might get a booster that will make you optimally protected, you don’t necessarily need to get it tomorrow,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases told CNN.

CDC Director Rochelle Walensky, MD, also weighed in. She told ABC that boosters for people who received a Moderna or Johnson & Johnson vaccine will be addressed with urgency.

“I want to reiterate that this is a very slow wane. There is no urgency here to go and get your booster immediately. You know, walk don’t run to your booster appointment,” she said.

“We will come and look at the data for Moderna and J&J in very short order.”

Both high C-reactive protein (CRP) and older age predict mortality from COVID-19 in patients with diabetes, new research suggests.

The data, from the retrospective ACCREDIT cohort study, were presented at the virtual annual meeting of the European Association for the Study of Diabetes (EASD 2021) by Daniel Kevin Llanera, MD.

The combination of older age and high levels of the inflammatory marker CRP were linked to a tripled risk for death by day 7 after hospitalization for COVID-19 among people with diabetes. But, in contrast to other studies, recent A1c and body mass index did not predict COVID-19 outcomes.

“Both of these variables are easily available upon admission to hospital,” Dr. Llanera, who now works at Imperial College, London, said in an EASD press release.

“This means we can easily identify patients early on in their hospital stay who will likely require more aggressive interventions to try and improve survival.”

“It makes sense that CRP and age are important,” said Simon Heller, MB BChir, DM, of the University of Sheffield, England. “It may be that diabetes alone overwhelmed the additional effects of obesity and A1c.

“Certainly in other studies, age was the overwhelming bad prognostic sign among people with diabetes, and perhaps long-term diabetes has effects on the immune system which we haven’t yet identified.”
 

Kidney disease in younger patients also linked to poorer outcomes

The study, conducted when Dr. Llanera worked for the Countess of Chester NHS Foundation Trust, involved 1,004 patients with diabetes admitted with COVID-19 to seven hospitals in northwest England from Jan. 1 through June 30, 2020. The patients were a mean age of 74.1 years, 60.7% were male, and 45% were in the most deprived quintile based on the U.K. government deprivation index. Overall, 56.2% had macrovascular complications and 49.6% had microvascular complications.

They had a median BMI of 27.6 kg/m², which is lower than that reported in previous studies and might explain the difference, Dr. Llanera noted.

The primary outcome, death within 7 days of admission, occurred in 24%. By day 30, 33% had died. These rates are higher than the rate found in previous studies, possibly because of greater socioeconomic deprivation and older age of the population, Dr. Llanera speculated.

A total of 7.5% of patients received intensive care by day 7 and 9.8% required intravenous insulin infusions.

On univariate analysis, insulin infusion was found to be protective, with those receiving it half as likely to die as those who didn’t need IV insulin (odds ratio [OR], 0.5).

In contrast, chronic kidney disease in people younger than 70 years increased the risk of death more than twofold (OR, 2.74), as did type 2 diabetes compared with other diabetes types (OR, 2.52).

As in previous studies, use of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers were not associated with COVID-19 outcomes, nor was the presence of diabetes-related complications.

In multivariate analysis, CRP and age emerged as the most significant predictors of the primary outcome, with those deemed high risk by a logistic regression model having an OR of 3.44 for death by day 7 compared with those at lower risk based on the two factors.

Data for glycemic control during the time of hospitalization weren’t available for this study, Dr. Llanera said in response to a question.

“We didn’t look into glycemic control during admission, just at entry, so I can’t answer whether strict glucose control is of benefit. I think it’s worth exploring further whether the use of IV insulin may be of benefit.”

Dr. Llanera also pointed out that people with diabetic kidney disease are in a chronic proinflammatory state and have immune dysregulation, thus potentially hindering their ability to “fight off” the virus.

“In addition, ACE2 receptors are upregulated in the kidneys of patients with diabetic kidney disease. These are molecules that facilitate entry of SARS-CoV-2 into the cells. This may lead to direct attack of the kidneys by the virus, possibly leading to worse overall outcomes,” he said.

Dr. Llanera has reported no relevant financial relationships. Dr. Heller has reported serving as consultant or speaker for Novo Nordisk, Eli Lilly, Sanofi Aventis, Mannkind, Zealand, MSD, and Boehringer Ingelheim.

Smokers are 80% more likely to be admitted to the hospital with COVID-19 than nonsmokers, according to an Oxford (England) University–led study.

Observational data was analyzed alongside hospital coronavirus test data and UK Biobank genetic information for the first time, and the findings are published in Thorax.

The data cover 421,469 people overall. Of these, 3.2% took a polymerase chain reaction swab test, 0.4% of these tested positive, 0.2% of them required hospitalization for COVID-19, and 0.1% of them died because of COVID-19.

When it came to smoking status, 59% had never smoked, 37% were ex-smokers, and 3% were current smokers.

Current smokers were 80% more likely to be admitted to hospital, and significantly more likely to die from COVID-19, than nonsmokers.
 

Time to quit

Heavy smokers who smoked more than 20 cigarettes a day were 6.11 times more likely to die from COVID-19 than people who had never smoked.

Analysis also showed those with a genetic predisposition to being smokers had a 45% higher infection risk, and 60% higher hospitalization risk.

The authors wrote: “Overall, the congruence of observational analyses indicating associations with recent smoking behaviors and [Mendelian randomization] analyses indicating associations with lifelong predisposition to smoking and smoking heaviness support a causal effect of smoking on COVID-19 severity.”

In a linked podcast, lead researcher Dr. Ashley Clift, said: “Our results strongly suggest that smoking is related to your risk of getting severe COVID, and just as smoking affects your risk of heart disease, different cancers, and all those other conditions we know smoking is linked to, it appears that it’s the same for COVID. So now might be as good a time as any to quit cigarettes and quit smoking.”

These results contrast with previous studies that have suggested a protective effect of smoking against COVID-19. In a linked editorial,  Anthony Laverty, PhD, and Christopher Millet, PhD, Imperial College London, wrote: “The idea that tobacco smoking may protect against COVID-19 was always an improbable one.”
