Adding the arthritis drug tocilizumab to standard care for patients in hospital with severe or critical covid-19 is no better than standard care alone in improving clinical outcomes at 15 days, finds a new trial published by The BMJ today.
There was an increased number of deaths at 15 days in patients receiving tocilizumab, resulting in the trial being stopped early.
Today’s results contradict earlier observational studies suggesting a benefit of tocilizumab. However, observational effects are limited by a high risk that they may be due to other unknown (confounding) factors – and some studies have not yet been peer reviewed or published in a medical journal.
Smoking is associated with an increased risk of COVID-19 symptoms and smokers are more likely to attend hospital than non-smokers, a study has found.
The study published today in Thorax, by researchers from King’s College London, investigates the association between smoking and the severity of the COVID-19.
Researchers analysed data from the ZOE COVID Symptom Study App. Of the participants of the app, 11% were smokers. This is a lower proportion than the overall UK population of 14.7%, however, it reflects the demographics of the self-selected sample of the ZOE COVID Symptom Study.
While more than a third of users reported not feeling physically well during the period of study (24th March and April 2020), current smokers were 14% more likely to develop the classic triad of symptoms suggesting diagnosis of COVID-19: fever, persistent cough and shortness of breath – compared to non-smokers.
A novel computational drug screening strategy combined with lab experiments suggest that pralatrexate, a chemotherapy medication originally developed to treat lymphoma, could potentially be repurposed to treat Covid-19. Haiping Zhang of the Shenzhen Institutes of Advanced Technology in Shenzhen, China, and colleagues present these findings in the open-access journal PLOS Computational Biology.
With the Covid-19 pandemic causing illness and death worldwide, better treatments are urgently needed. One shortcut could be to repurpose existing drugs that were originally developed to treat other conditions. Computational methods can help identify such drugs by simulating how different drugs would interact with SARS-CoV-2, the virus that causes Covid-19.

The combination of baricitinib, an anti-inflammatory drug, and remdesivir, an antiviral, reduced time to recovery for people hospitalized with COVID-19, according to clinical trial results published in the New England Journal of Medicine. The study was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
The clinical trial is the second iteration of the NIH Adaptive COVID-19 Treatment Trial (ACTT-2), a study protocol to evaluate therapeutics for people hospitalized with COVID-19. Remdesivir is a broad-spectrum antiviral treatment developed by Gilead Sciences, Inc. Baricitinib was discovered by Incyte and licensed to Eli Lilly and Company, and marketed under the brand name Olumiant. It is approved in more than 70 countries as a treatment for adults with moderately-to-severely active rheumatoid arthritis. Researchers hypothesized that because many severe symptoms of COVID-19 are caused by a poorly regulated inflammatory response, a therapeutic designed to target inflammation could be helpful for patients. The primary results of this study were first announced in September.
Potential treatments for Covid-19 have been identified after the discovery of five genes associated with the most severe form of the disease.
Genetic evidence is second only to clinical trials as a way to tell which treatments will be effective in a disease. Existing drugs that target the actions of the genes reveal which drugs should be repurposed to treat Covid-19 in clinical trials, experts say.
Genes involved in two molecular processes – antiviral immunity and lung inflammation – were pinpointed. The breakthrough will help doctors understand how Covid-19 damages lungs at a molecular level.
Researchers from the University of Edinburgh made the discovery by studying the DNA of 2,700 patients in 208 intensive care units (ICUs) in the UK.
Researchers from the GenOMICC consortium – a global collaboration to study genetics in critical illness – compared the genetic information of Covid-19 patients in ICU with samples provided by healthy volunteers from other studies, such as UK Biobank, Generation Scotland and 100,000 Genomes.
