Slower clearance of coronavirus infection may explain why men fare worse than women

Why do men have trouble shaking off their infections? Seeking a molecular explanation, the researchers focused on how coronavirus infection occurs. To infect cells, coronaviruses must first latch onto well-known proteins, called ACE2 receptors, that sprout like tiny antennae from the surfaces of cells. Cell types expressing copious levels of ACE2 on their surfaces would theoretically be most susceptible to infection.

Researchers at Montefiore Health System and Albert Einstein College of Medicine may have solved a mystery surrounding the novel coronavirus pandemic: Why men infected by the virus generally show more severe symptoms and are more likely than women to die from COVID-19.

In collaboration with the Kasturba Hospital for Infectious Diseases in Mumbai, India, the scientists showed for the first time that men clear the virus from their bodies slower than women and found a possible explanation: a potential male-only “reservoir” for coronavirus.

Their study was uploaded to MedRxiv, a website created by Cold Spring Harbor Laboratory to make research quickly available to the scientific community before undergoing the usual peer review process. It has become widely used to share information quickly during the COVID-19 pandemic.

“COVID-19 studies worldwide have consistently shown a higher incidence and greater severity of the disease in men compared with women,” says Aditi Shastri, M.D., assistant professor of medicine at Einstein, a clinical oncologist at the Montefiore Einstein Center for Cancer Care, and lead author of the Montefiore-Einstein study. “Our collaborative study found that men have more difficulty clearing coronavirus following infection, which could explain their more serious problems with COVID-19 disease.”

The viral-clearance analysis involved 68 people (48 men and 20 women) with symptoms of COVID-19 who were examined at India’s Kasturba Hospital for Infectious Diseases, in Mumbai. After undergoing initial nasal swab tests indicating active infection, individuals were re-tested with serial swabs until the tests turned negative, indicating the time taken to clear the coronavirus. The women cleared the virus significantly earlier than men: a median of four days for women vs. six days for men.

Next, three Mumbai families were identified in which men and women had tested positive for coronavirus infection on swab testing. Again, the women in all three families cleared the coronavirus earlier than male members of the same family.

Why do men have trouble shaking off their infections? Seeking a molecular explanation, the researchers focused on how coronavirus infection occurs. To infect cells, coronaviruses must first latch onto well-known proteins, called ACE2 receptors, that sprout like tiny antennae from the surfaces of cells. Cell types expressing copious levels of ACE2 on their surfaces would theoretically be most susceptible to infection.

The researchers consulted three independent databases with information on ACE2 expression in different tissues. They saw that the testes, along with the lungs and kidneys, were among the areas of the body with the highest ACE2 expression. By contrast, ACE2 could not be detected in tissue of the ovaries, the female equivalent of the testes.

Dr. Shastri stresses that the novel coronavirus’ ability to infect and multiply in testicular tissue needs to be confirmed, but says it wouldn’t surprise her. A recent study from China compared the levels and ratios of sex hormones in male COVID-19 patients vs. healthy men of the same age. The results indicated that the COVID-19 patients had experienced impaired testicular function—evidence that the testes may be significantly affected when men develop COVID-19. Such a COVID-19 complication could have important medical and public health implications, she notes, and deserves to be investigated by clinical trials.

The study’s Montefiore-Einstein senior authors are Amit Verma, M.B.B.S., professor of medicine and of developmental & molecular biology at Einstein and director of hematologic malignancies at Montefiore; and Ulrich Steidl, M.D., Ph.D., professor of cell biology and of medicine and the Diane and Arthur B. Belfer Faculty Scholar in Cancer Research at Einstein, and associate chair for translational research in oncology at Montefiore.

The study’s other senior author is Jayanthi Shastri, M.D., a microbiologist and infectious disease specialist. As director of Kasturba Hospital’s molecular diagnostic laboratory, Dr. Jayanthi Shastri led Mumbai’s effort to serially monitor and analyze coronavirus infection in individuals and their family members.

Research suggests drinking coffee may reduce the risk of frailty

Habitual coffee consumption of 4-6 cups and over* (with one cup measuring at 125ml) per day is associated with a reduced risk of frailty.

Published

A new study published in the European Journal of Nutrition has suggested that habitual coffee consumption of 4-6 cups and over* (with one cup measuring at 125ml) per day is associated with a reduced risk of frailty.

The study, funded by the Institute for Scientific Information on Coffee (ISIC) is the first to analyze the relationship between coffee consumption and the underlying components of frailty.

Coffee consumption has previously been linked to reducing the risk of some of the natural symptoms of ageing, such as improving cognitive function2 and mitigating against inflammatory related diseases. This latest research adds to the growing knowledge base within this area, exploring the benefits of regular coffee consumption over an extended period of time. 

For this study, researchers conducted a detailed analysis over a long seven-year follow-up period, surveying 1,161 adults aged 55+ years through the Longitudinal Aging Study Amsterdam (LASA). 

The relationship between coffee consumption and the presence and incidence of frailty was investigated. Frailty status was evaluated using Fried’s five-component frailty phenotype4,which is defined by the presence of three or more of the following symptoms: weight loss, weakness, exhaustion, slow gait (walking) speed, and low physical activity.

The results of this study indicate that higher habitual coffee consumption is associated with lower overall odds of frailty. These findings can be considered alongside the European Food Safety Authority’s (EFSA) scientific opinion that up to 400mg of caffeine (3-5 cups of coffee) per day is a moderate and safe amount5.

The researchers explain that coffee’s effect on reducing frailty can partly be attributed to the role of antioxidants in coffee, which may help to reduce inflammation, sarcopenia (muscle loss), and prevention of muscle damage. Coffee may also help to improve regulating insulin sensitivity and glucose uptake in older people.

The study’s lead author, Margreet R. Olthof, Associate Professor at the Amsterdam Public Health Research Institute, Vrije Universiteit Amsterdam, commented: “Drinking coffee is a key part of many people’s daily routine, and as people age they are constantly looking for ways to maintain their health. Our findings highlight the possible beneficial association between daily coffee consumption and reduced risk of frailty in later life in the older population. Coffee consumption may thus enhance healthy aging, but it is important we also explore further dietary interventions, to ensure older adults can continue to live fulfilling lives.” 

* Moderate coffee consumption can be defined as 3–5 cups per day, based on the European Food Safety Authority’s review of caffeine safety.

Cannabidiol therapy could reduce symptoms in autistic children and teenagers

The use of cannabidiol (CBD) cannabis extract can lead to meaningful benefits and improve the behaviour of children and adolescents with autism spectrum disorder.

Published

on

New research presented at the 2025 European Congress of Psychiatry reveals that the use of cannabidiol (CBD) cannabis extract can lead to meaningful benefits and improve the behaviour of children and adolescents with autism spectrum disorder (ASD). ASD affects approximately 1 in 100 children around the world and symptoms can include difficulty interpreting language, difficulty expressing emotions, and repetitive behaviour and routines.1,2 

The meta-analysis included randomised, placebo-controlled trials on the efficacy or safety of CBD cannabis extracts in children and adolescents with ASD. Three studies were used in total with 276 participants with a mean age of 10.5, ranging in age from 5 to 21. The dosage of CBD cannabis extract started at 1 mg/kg per day and was titrated up to 10 mg/kg.  

Key findings from the study include: 

  • CBD cannabis extract use shows moderate improvements in social responsiveness and small yet notable reductions in disruptive behaviours.
  • CBD cannabis extract significantly enhanced social responsiveness and reduced disruptive behaviour.
  • The use of CBD cannabis extract has a favourable safety profile as it did not increase adverse events compared to placebo  
  • There were no significant differences between adverse events in CBD cannabis extract versus placebo  

Lara Cappelletti Beneti Branco, Lead Investigator, São Camilo University Center, University of São Paulo, said: “The global population prevalence of ASD diagnosis amongst children and adolescents is growing, but many treatment pathways are not effective. It is promising to see the effect of CBD cannabis extract on the study participants. However, there still needs to be considerable focus on further research with larger trials to clarify its efficacy and safety in managing ASD.” 

Professor Geert Dom, EPA President, said: “ASD can be extremely frustrating for all involved; parents of children and adolescents with the disorder, the treating clinicians and of course the children and adolescents themselves. A large part of this frustration is down to finding a viable treatment option that works to reduce symptoms. It is with delight that we see the results of this meta-analysis and we hope to see further research into this so we can move towards a solution to the unmet need within this community”.
