02/18/2021 16:00 GMT — Azithromycin has no effect on survival outcomes for patients hospitalized with COVID-19

Some researchers and medical practitioners believe that azithromycin, a common antibiotic, might help improve outcomes for some people who test positive for COVID-19 and who do not require hospitalization.

Moreover, some studies from 2020 suggest that administering this antibiotic to patients hospitalized with COVID-19 appeared to reduce mortality rates due to the disease.

Additionally, an online survey conducted last spring by Sermo, a private social media network for physicians, indicates that 41% of physicians who treat patients with COVID-19 prescribed them azithromycin, making this antibiotic the second most commonly prescribed medication for this disease.

Now, the RECOVERY Collaborative Group — in charge of the RECOVERY clinical trial, which tests potential COVID-19 treatments — have announced that, according to their data, this antibiotic does not improve mortality outcomes in patients hospitalized with COVID-19.

The study paper, which appears in The Lancet, reports that the researchers monitored 7,763 hospitalized patients, 2,582 of whom received azithromycin.

“Overall, 561 (22%) patients allocated to azithromycin and 1,162 (22%) patients allocated to usual care died within 28 days,” the paper states, suggesting that the antibiotic “did not improve survival” among those treated for COVID-19 in a hospital setting.

02/18/2021 09:14 GMT — UK set to run world’s first coronavirus Human Challenge study

In the next few weeks, the United Kingdom will embark on the world’s first Human Challenge study. As a government press release explains, part of the research will “involve establishing the smallest amount of virus needed to cause infection.”

Scientists will recruit 90 healthy adult volunteers and expose them to SARS-CoV-2 in a safe and controlled environment.

In their press release, the government explain that the study “will give doctors greater understanding of COVID-19 and help support the pandemic response by aiding vaccine and treatment development.”

Following the initial trial, scientists will give vaccine candidates to healthy participants before exposing them to SARS-CoV-2. According to their press release, this will help “identify the most effective vaccines and accelerate their development.”

Speaking about the upcoming research, Interim Chair of the Vaccines Taskforce Clive Dix says:

“We have secured a number of safe and effective vaccines for the U.K., but it is essential that we continue to develop new vaccines and treatments for COVID-19. We expect these studies to offer unique insights into how the virus works and help us understand which promising vaccines offer the best chance of preventing the infection.”

02/18/2021 08:53 GMT — Lockdown may have boosted well-being for some

A recent study of people who care for children concludes that COVID-19 lockdowns have provided some unexpected benefits. Some people reported positive changes in their family relationships, spiritual well-being, and more. The results appear in the British Journal of Psychiatry.

When the researchers asked participants, “Do you think there are any positives to come out of this pandemic and the social distancing restrictions?” 88.6% responded “yes.”

However, there are limitations. The study was relatively small and included participants who were, as the authors explain, “highly educated mothers.” It is not possible to know how the results would have differed in other groups.

Similarly, the study primarily included mothers who had intact nuclear families with one or two children aged 6–16 years. The results may not be applicable to single parents and caregivers and those with younger children.

02/17/2021 08:39 GMT — Allocetra may improve outcomes for people with severe or critical COVID-19 

In a press release, Enlivex Therapeutics outline the results of a recent trial investigating the benefits of their drug — Allocetra — for people with severe or critical COVID-19. The results are encouraging, but the study has important limitations.

The phase 2 clinical trial included data from just 21 people. All participants had severe or critical COVID-19. By day 28, none had died, and 19 of the 21 had left the hospital.

Prof. Stephen Evans, a professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine in the United Kingdom, who was not involved in the study, adds some context:

“The results here are not from a randomized or controlled trial; it is effectively an observational study. Even though the results look encouraging […] the results are statistically compatible with a mortality rate of over 20%.”

He calls for randomized controlled trials that compare Allocetra, which is not yet licensed, with dexamethasone, which is relatively cost effective, easily available, and proven to be effective in similar patients.

02/17/2021 08:36 GMT — Winter COVID-19: Climate less important than control measures

COVID-19 rates have spiked in the winter months in the Northern Hemisphere and in summer months in the Southern Hemisphere. However, a new study suggests that the current winter peaks result from relaxing control measures — not changing climatic conditions.

02/12/2021 16:30 GMT — People with disabilities account for 6 out of 10 COVID-19 deaths in England

In the United Kingdom, the Office for National Statistics (ONS) have just released data showing that people with disabilities account for six out of 10 COVID-19 deaths.

The data cover the entire period of the pandemic up to November 20, 2020. During this time, 30,296 of 50,888 people who died had disabilities. Of the total study population, only 17.2% were living with disabilities, which suggests that the pandemic affects this group of people to a disproportionate degree.

The data also show that men with disabilities were 3.1 times more likely to die from COVID-19 compared with men without disabilities. Among women with disabilities, this risk was 3.5 times greater.

02/12/2021 14:30 GMT — Gastrointestinal symptoms in COVID-19: What we know so far

Respiratory symptoms are the most common symptom of COVID-19. However, according to some recent studies, over half of people hospitalized with COVID-19 also experience at least one gastrointestinal (GI) symptom.

Furthermore, evidence increasingly suggests that having GI symptoms with COVID-19 or developing COVID-19 in addition to preexisting GI conditions may raise the risk of disease severity and complications.

In a Special Feature, Medical News Today round up the evidence that we have so far on the relationship, prevalence, and impact of GI symptoms in SARS-CoV-2 infections.

02/11/2021 14:20 GMT — Japan declares it will discard millions of vaccine doses, due to unsuitable syringes

Japan’s health minister, Norihisa Tamura, has announced that the country will have to discard millions of doses of Pfizer’s COVID-19 vaccine.

This is because Japan does not have enough suitable syringes for the extraction of six doses per vial. These are the so-called “low dead space” syringes, which have less space between the plunger and the needle, meaning that they can draw more liquid.

The standard syringes in the country are “high dead space,” and they can only be used to extract five doses from a vial. This will be enough to vaccinate 60 million people.

Japan had acquired 144 million shots of the Pfizer vaccine, which would have been enough to vaccinate 72 million people — if, and only if, healthcare practitioners could extract six doses from each vial.

02/11/2021 14:15 GMT — FDA issue EUA for two monoclonal antibodies as COVID-19 treatment

On February 9, the Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for two monoclonal antibodies — bamlanivimab and etesevimab — as a treatment for mild to moderate COVID-19.

Bamlanivimab and etesevimab will be administered together through an intravenous infusion. They are recommended for emergency use in adults and in children aged at least 12 and weighing at least 40 kilograms.

However, this treatment is not recommended for those already hospitalized with COVID-19 or those who are receiving oxygen therapy for the disease.

“The data supporting this emergency authorization add to emerging evidence that points to the clinical utility of neutralizing antibodies for the treatment of COVID-19 in certain patients,” said Dr. Patrizia Cavazzoni, acting director of the FDA Center for Drug Evaluation and Research.

02/11/2021 09:51 GMT — mRNA vaccines may be slightly less effective against some SARS-CoV-2 variants

02/10/2021 08:51 GMT — SARS-CoV-2 unlikely to have escaped from Chinese lab, according to WHO

A delegation of experts from the World Health Organization (WHO) recently completed a 4-week visit to Wuhan, China. Considering their findings, Peter Ben Embarek, who led the investigation, believes that the virus is unlikely to have escaped from a laboratory.

“The findings suggest that the laboratory incidents hypothesis is extremely unlikely to explain the introduction of the virus to the human population,” he explains.

The team also found no evidence that the virus was spreading widely before the initial outbreak in December 2020.

“We haven’t been able to fully do the research, but there is no indication there were clusters before what we saw happen in the later part of December in Wuhan,” explains Liang Wannian, who led the Chinese experts who were involved in the WHO mission.

02/04/2021 09:10 GMT — SARS-CoV-2 can impact metabolism by infecting pancreas cells

A new study, which appears in Nature Metabolism, settles a long-standing debate. Using a multipronged approach, the researchers demonstrate that SARS-CoV-2 can infect beta-cells, which are the pancreatic cells that produce insulin. They also showed that this infection can disrupt beta-cell function.

Although scientists initially considered COVID-19 a disease of the lungs, they have shown that it impacts a range of organs, including the brain and heart.

There is also evidence that COVID-19 impacts glucose metabolism. For instance, a meta-analysis showed that severe COVID-19 was associated with increased blood glucose. 

The authors conclude, “Our data identify the human pancreas as a target of SARS-CoV-2 infection and suggest that beta-cell infection could contribute to the metabolic dysregulation observed in patients with COVID-19.”

02/02/2021 15:32 GMT — The B.1.1.7 coronavirus picks up ‘worrying’ mutations in the UK

A report by Public Health England (PHE) describes 11 instances of an additional mutation in the B.1.1.7 SARS-CoV-2 variant. The particular mutation, called E484K, is also present in the variants first identified in Brazil and South Africa. 

Scientists first identified the B.1.1.7 variant in the United Kingdom last year. Some people refer to it as the “U.K. variant.” Modeling data indicate that this variant is more likely to pass from person to person. 

Additional variants that researchers identified in South Africa and Brazil carry some of the same mutations as B.1.1.7. What has set them apart until now is the addition of the E484K mutation in the spike protein. It appears to make vaccines and monoclonal antibodies less effective at fighting off the virus. 

Prof. Jonathan Stoye, a group leader at the Francis Crick Institute in London, U.K. — whose laboratory studies virus-host interactions — provided comments on the report by PHE: 

“The E484K mutation [has] now been identified in a small fraction of viruses carrying sequence differences defining the U.K. variant,” he says. “This suggests that the U.K. variant is now independently acquiring the E484K change.”

“From a virological standpoint, appearance of new variants by mutation during replication cannot be considered surprising. Whether this change will provide significant growth advantages for the novel virus causing it to predominate remains to be seen,” Prof. Stoye continues. “This report would seem to suggest that under conditions of very high levels of virus replication even the most stringent of border controls, although they may delay spread, are unlikely to prevent the appearance of new variants.” 

“This updated PHE report on the U.K. B.1.1.7 [variant] mentions the acquisition of the E484K mutation — which is a worrying development, though not entirely unexpected,” adds Dr. Julian Tang, a clinical virologist from the University of Leicester in the U.K. 

“This is another reason to follow the COVID-19 restrictions/infection control measures more strictly — otherwise not only can the virus continue to spread, it can also evolve,” he adds.

02/01/2021 09:10 GMT — WHO team visits Wuhan wet markets

Yesterday, a number of experts from the World Health Organization (WHO) visited the wet market in Wuhan, China, that is linked to some of the earliest cases of COVID-19. They hope that this visit might provide clues as to how the virus spread so widely.

Earlier in their trip, the experts visited a museum dedicated to the early days of COVID-19, as well as two hospitals in the region and the Baishazhou market, one of the largest wet markets in Wuhan.

Understanding the complex genesis of SARS-CoV-2 is likely to be a long project, but the experts hope that visits such as these might illuminate further avenues of investigation. 

As one of the team, zoologist Dr. Peter Daszak, explains, the visit is “critical for our joint teams to understand the epidemiology of COVID-19 as it started to spread at the end of 2019.”

In response to reduced infection rates and hospitalization, some states are beginning to ease restrictions. For instance, in Michigan, restaurants are open to indoor dining for the first time in 10 weeks. However a 10 p.m. curfew is in place, and their capacity is limited.

Gretchen Whitmer, Michigan’s governor, explained: “We are in a stronger position because we have taken this pause. But we are also very mindful of the fact that this variant is now here in Michigan. It poses a real threat.”

Similarly, Washington, D.C., has recently reopened indoor dining for the first time this year. In California, Governor Gavin Newsom has removed stay-at-home orders, and restaurants and places of worship can now operate outdoors.

In Oregon, officials have announced that from tomorrow gyms and movie theaters can reopen but with limited capacity.

Experts are rightfully cautious about reopening too soon. Dr. Joshua Sharfstein, vice dean for public health practice and community engagement at Johns Hopkins University in Baltimore, MD, said:

“I do not think it is unreasonable to start to reopen, but if people think that is the green light to pretend the virus does not exist, then we are going to be right back to where we were. If you do restrictions, the virus goes down. You can open up and see how it goes. But if the variants really take hold, that may not be so easy.”

01/27/2020 09:21 GMT — Problems with EU vaccine rollout

The European Union has been criticized for the slow pace of vaccine distribution across its member states. In December, the E.U. approved the purchase of 300 million doses of the Pfizer-BioNTech vaccine. However, due to miscommunication and supply chain problems, Pfizer have not been able to meet expectations.

01/27/2021 09:18 GMT — Eli Lilly’s monoclonal antibody combo treatment reduces COVID-19 severity

A press release from Eli Lilly outlines encouraging findings from recent Phase 3 trials. They found that a combination of monoclonal antibodies bamlanivimab (LY-CoV555) and etesevimab (LY-CoV016) reduces the risk of COVID-19 hospitalization and death by 70%.

According to the press release, the study included data from 1,035 “high risk patients recently diagnosed with COVID-19.” Of those who received the monoclonal antibodies, 2.1% were hospitalized or died, compared with 7% of those who took the placebo.

In total, there were 10 deaths, all of which occurred in the placebo group. According to the press release, “These exciting results, which replicate positive Phase 2 data in a much larger set of patients, add valuable clinical evidence about the role neutralizing antibodies can play in fighting this pandemic.”

Prof. Stephen Evans, a professor of pharmacoepidemiology at London School of Hygiene & Tropical Medicine in the United Kingdom, who was not involved in the study, says:

“These results are very encouraging. They are the first antiviral drugs that demonstrably work in the first phase of the disease, just after the virus has infected someone but before it has had time to cause a lot of damage.”

However, Prof. Evans also outlines some limitations. For instance, he is concerned that the cost of the treatment may be quite high and that the drugs need to be given by infusion.

He also questions how much of an impact this type of therapy could have: “Identifying patients who test positive and are at high risk of hospitalization and death prior to their admission to hospital is not simple. It is not clear whether this could be many tens of thousands of patients or relatively few.”

According to a recent study, bamlanivimab, a monoclonal antibody drug manufactured by Eli Lilly and Co., helps prevent COVID-19 in nursing homes. The study involved 299 residents and 666 members of staff. For the residents, bamlanivimab reduced the risk of COVID-19 by 80% during a SARS-CoV-2 outbreak.

However, when the researchers analyzed data from the residents and staff together, they found that the drug reduced the risk of developing COVID-19 symptoms by 57%. Compared with a placebo, bamlanivimab was also associated with a lower risk of COVID-19 mortality and lower viral loads.

The results are encouraging, but as vaccine rollouts focus on older adults, the need for drugs of this type will be reduced. By the time the FDA provide a new emergency use authorization, relatively few nursing home residents and staff should be left unvaccinated.

A recent study investigated how the pandemic has influenced traditional gender roles in child care. The researchers found that child care responsibilities tended to fall to women during the initial wave of the COVID-19 pandemic in the United States. The findings appear in theJournal of Applied Psychology.

Overall, the researchers found that couples working alternating days generally had the best outcomes, with both husbands and wives in this category experiencing the most sleep and the lowest psychological distress. The scientists compared this with couples trying to work in ‘mini-shifts’ or having one parent attempting to do all the child care.

01/19/2021 09:13 GMT — Almost 1 in 3 people treated for COVID-19 in hospitals readmitted after discharge

A recent study tracked 47,780 COVID-19 patients for almost 5 months following hospital discharge. They compared the outcomes of this group with those of matched individuals who had been admitted for reasons unrelated to COVID-19. The people who had received hospital treatment for COVID-19 were 3.5 times more likely to be readmitted.

The group treated for COVID-19 were also 7.7 times more likely to die than those treated for other reasons. The results of the study appear on the preprint server MedRxiv. Older adults and people who were not white had the greatest risk of readmission and death.

The authors conclude: “Individuals discharged from hospital following COVID-19 face elevated rates of multiorgan dysfunction, compared with background levels, and the increase in risk is neither confined to the elderly nor uniform across ethnicities.”

01/18/2021 08:58 GMT — Most hospitalized COVID-19 patients still have symptoms after 6 months

A recent study showed that more than three-quarters of a cohort of COVID-19 patients still had at least one symptom 6 months after being discharged from the hospital. Dubbed “long COVID,” common symptoms include fatigue, coughing, muscle aches, chest pain, heart palpitations, and rashes.

The results appear in the journal The Lancet. Corresponding author Prof. Bin Cao explains that “because COVID-19 is such a new disease, we are only beginning to understand some of its long-term effects on patients’ health.” He continues:

“Our analysis indicates that most patients continue to live with at least some of the effects of the virus after leaving hospital and highlights a need for postdischarge care, particularly for those who experience severe infections.”

01/15/2021 12:02 GMT — Brazilian variant detected in UK

According to scientists, a new variant they believe to have first appeared in Brazil is already in the United Kingdom. Although the variant is distinct from those first spotted in the U.K. and South Africa, it shares certain mutations.

“The Brazilian variant has three key mutations in the spike receptor binding domain (RBD) that largely mirror some of the mutations we are worried about it in the South African variant, hence the concern,” explains Prof. Ravi Gupta, a professor of microbiology at the University of Cambridge in the U.K.

“The SARS-CoV-2 RBD is one of the main targets for our immune defences and also the region targeted by vaccines and changes within this region are therefore worrisome. Vaccines are still likely to be effective as a control measure if coverage rates are high and transmission is limited as far as possible.”

01/15/2021 09:00 GMT — COVID-19: Gut bacteria may influence severity

The authors of a recent study conclude that an individual’s gut microbiome might affect how their body responds to a SARS-CoV-2 infection. More specifically, gut bacteria might influence both the short- and long-term effects of the infection. The results appear in the journal Gut.

Overall, the authors conclude: “Associations between gut microbiota composition, levels of cytokines, and inflammatory markers in patients with COVID-19 suggest that the gut microbiome is involved in the magnitude of COVID-19 severity, possibly via modulating host immune responses.”

The scientists also believe that gut bacteria could play a role in the development of long COVID.

01/13/2021 09:02 GMT — Large-scale study to test interferon beta

Researchers are still working hard to identify and trial drugs that can reduce the severity of COVID-19. One such drug is interferon beta. Scientists in the United Kingdom are embarking on a large-scale study to find out if it can prevent severe COVID-19 symptoms from emerging.

The experimental treatment is an inhaled version of interferon beta, which biotech company Synairgen developed at Southampton University Hospital in the U.K.

Interferon beta is one of the first cytokines to be released during an infection. The protein is the primary driver of the immune response in the lung. SARS-CoV-2 suppresses the release of interferon beta, and the researchers believe that by inhaling the cytokine into the lungs, it will produce a stronger immune response against the virus. 

Last year, a smaller study involving 101 people produced encouraging results.

As the authors concluded, “Patients who received [interferon beta] had greater odds of improvement and recovered more rapidly from SARS-CoV-2 infection than patients who received placebo, providing a strong rationale for further trials.”

The scientists say that they should be able to complete the study by the summer.

01/12/2021 12:35 GMT — Russia to conduct clinical trial for “Sputnik-Light” vaccine

On Monday, Russian authorities declared that, in order to ensure COVID-19 vaccine doses reach enough people, they will test out a one-dose regimen of Sputnik V.

Sputnik V is a COVID-19 vaccine developed by the Gamaleya Research Institute of Epidemiology and Microbiology in Moscow, which was first approved for provisional use in Russia last fall.

The experimental one-dose regimen is dubbed “Sputnik-Light,” and researchers are set to test it in 150 volunteers.

In the meantime, Russia will continue to roll out the two-dose Sputnik V vaccination regimen.

Russian officials have hinted that if the trial of Sputnik-Light is successful, they may make the modified vaccine available for export.

According to Kirill Dmitriev, head of the Russian Direct Investment Fund, which funds the new trial, “‘Sputnik-Light’ can serve as an effective temporary solution for many countries, which are experiencing a peak of coronavirus infection.”

01/12/2021 10:45 GMT — Immunity against SARS-CoV-2 may last at least 8 months

In a new study published in Science, researchers found that immune responses that can fight off SARS-CoV-2 have persisted for more than 8 months after people recovered from COVID-19.

The team from La Jolla Institute in California, led by Prof. Alessandro Sette and Prof. Shane Crotty, analyzed 254 blood samples from 188 individuals who recovered from COVID-19. Of these, 43 samples were taken at least 6 months after the infection with the virus.

The researchers found antibodies, T cells, and memory B cells specific to SARS-CoV-2 to varying degrees, suggesting immunity to severe COVID-19 in most study participants. However, there was variation, and some of the volunteers did not have significant levels of immunity. 

This may be why some people can develop COVID-19 more than once.

01/12/2021 10:11 GMT — Gorillas in San Diego Zoo have COVID-19

After tigers, lions, cats, dogs, and mink, gorillas are the latest animals to contract SARS-CoV-2 outside of lab studies. A press release from the San Diego Zoo, in California, suggests that the virus likely passed to the gorillas from a staff member with an asymptomatic SARS-CoV-2 infection.

After two members of the gorilla troop at the zoo started coughing last week, testing of fecal samples confirmed the presence of SARS-CoV-2. 

“Aside from some congestion and coughing, the gorillas are doing well,” Lisa Peterson, the executive director of the San Diego Zoo Safari Park, said. “The troop remains quarantined together and are eating and drinking. We are hopeful for a full recovery.”

01/11/2021 17:52 GMT — Is there a link between COVID-19 and long-term neurological problems?

Researchers studying the effects of past viral illnesses, including the 1918 flu, on cognitive function suggest that COVID-19 may have long-lasting effects on the brain. However, more research is necessary to draw any conclusions.

Writing in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, Dr. Gabriel A. de Erausquin from the University of Texas Health Science Center at San Antonio and collaborators share their perspective on what data from past viral infections may mean for people who recover from COVID-19.

The scientists suggest a link between a person’s risk for neurological disorders, such as Alzheimer’s disease, Parkinson’s disease, and mental health problems, and infection with respiratory viruses. Among the viruses, they cite H1N1, which caused the 1918 flu pandemic, and the SARS-CoV virus, which caused the 2003 SARS epidemic.

Like the new coronavirus, these respiratory viruses are able to infect cells in the brain. The scientists suggest that even people who have had an asymptomatic SARS-CoV-2 infection may be at increased risk of lasting effects on the brain.

Scientists will need to run longer-term studies to see whether they can confirm this theory.

01/07/2021 08:33 GMT — Study finds new evidence of SARS-CoV-2 damaging brain blood vessels

In a recent study, scientists did not find SARS-CoV-2 in the brains of people with the infection. However, in the post-mortem brains of patients who tested positive for COVID-19, they found blood vessel damage caused by inflammation. The results appear in the New England Journal of Medicine.

“We were completely surprised. Originally, we expected to see damage that is caused by a lack of oxygen,” says senior author Dr. Avindra Nath. “Instead, we saw multifocal areas of damage that is usually associated with strokes and neuroinflammatory diseases.”

Dr. Nath plans to continue investigating: “In the future, we plan to study how COVID-19 harms the brain’s blood vessels and whether that produces some of the short- and long-term symptoms we see in patients.”

01/05/2021 10:10 GMT — UK begins third lockdown

Yesterday evening, the United Kingdom’s prime minister, Boris Johnson, announced the U.K.’s third lockdown. Although the U.K. government decided to let pupils return to school on Monday, they reversed the decision that evening. Learning will move online, while people should work from home where possible.

Johnson said the decision is due to the rise of a new variant of SARS-CoV-2, first identified in the U.K. This variant may be more transmissible, although it does not appear to increase the risk of worse disease.

For many experts, this move is unsurprising and arrived too late. Dr. Julian W Tang, honorary associate professor and clinical virologist at the University of Leicester, says:

“We sort of predicted the likely need for this post-Xmas and New Year lockdown because we knew that many people would still try to meet up over the festive season — and we cannot really blame the new variant virus for all of this.”

He continues, “Yet this brief freedom will have long-term costs for business and education — and people’s health, both COVID-19 and non-COVID-19-related.”

In his televised statement, Johnson said, “The weeks ahead will be the hardest yet, but I really do believe that we are entering the last phase of the struggle, because with every jab that goes into our arms, we are tilting the odds against [COVID-19] and in favor of the British people.”

Talking about the latest U-turn, Dr. Catherine Carroll-Meehan, Head of School of Education and Sociology, University of Portsmouth, says, “Closing schools is the right decision. What families, children, and schools need is some certainty. It is a shame that the government do not take decisions in a more certain and timely manner.”

The new lockdown will continue until mid-February.
