Long after recovery from COVID-19, people face significantly higher risks for new heart problems, a large study has found. Risk of new heart problems much higher after COVID recovery They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. Feb 9 (Reuters) - The following is a summary of some recent studies on COVID-19. These include its retrospective design and the limited access they had to other demographic and medical information about patients that could have influenced clinical outcomes.įor live updates on the latest developments regarding the novel coronavirus and COVID-19, click here. In their paper, the authors acknowledge several limitations of their study. They say that more research is necessary to explain why liver damage appears to be so much worse among COVID-19 patients in the U.S. The team is conducting further clinical and laboratory-based studies to investigate the effects of COVID-19 on the liver. However, because doctors were more likely to prescribe drugs such as tocilizumab to the most critically ill patients, it was not possible to determine whether the treatment or the disease was responsible for causing liver damage. “We observed a strong association between the use of COVID-19 medications and abnormal liver tests,” says Dr. This is especially true in the case of a drug called tocilizumab. The study also uncovered an association between liver damage and some of the medications that doctors are using to treat COVID-19. ![]() The study authors write that this likely reflects direct damage by the virus elsewhere in the body, rather than damage to the liver itself.Įven though liver cells carry the ACE2 receptors that the virus uses to gain entry to cells, the researchers’ analysis suggests that most of the damage is due to inflammation resulting from an infection elsewhere - namely, the bile duct. ![]() Regardless of whether they developed liver problems before or after hospitalization with COVID-19, having abnormal test results was associated with worse outcomes from the illness.Īfter adjusting for other risk factors - including age, sex, body mass index (BMI), and the presence of diabetes - the researchers found that patients with abnormal liver tests were more likely to need intensive care, more likely to require mechanical ventilation, and more likely to die. When the researchers looked at the patients’ medical records, they found that around one-quarter of them had abnormal liver tests before contracting SARS-CoV-2. In addition, millions of people have chronic liver infections due to hepatitis B and hepatitis C. The National Institutes of Health (NIH) estimate that 30–40% of adults in the U.S. Nonalcoholic fatty liver disease (NAFLD) has links to obesity, high blood pressure, diabetes, and high cholesterol levels. Joseph Lim, the director of the Yale Viral Hepatitis Program. patients may have an increased rate of other risk factors, such as alcoholic or nonalcoholic fatty liver disease,” says senior study author Dr. are more likely to have sustained damage, but underlying health differences between Chinese and U.S. The researchers are unsure why the livers of COVID-19 patients in the U.S. ![]()
