There is one clinical trial.
A team at the University of Manchester are developing a test that tcould be helpful in detecting immunity to the Coronavirus (which causes the COVID-19 disease) in participants with inflammatory arthritis. It is based on a flu assay has already developed; the team will replace the flu antigen with a Coronavirus antigen to see if it is effective. This project aims to develop a test to see if people who have had the virus have developed immunity to it. This could help to predict who might or might not get the disease a second time, who should stay at home to be protected from potential infection or who will not develop any symptoms, even if exposed to the virus. When vaccination trials against the Coronavirus will be launched, this test could also help to see if the vaccine is effective.
Description: the prevalence and abundance of CD4+ T lymphocytes specifically recognizing SARS-CoV-2 in COVID-19 patients with inflammatory arthritis, in pre- and post-infection samples; in patients without COVID-19 and in healthy volunteers with or without COVID-19. Correlation of these cells with COVID-19 severity.
Measure: Prevalence and abundance of CD4+ T lymphocytes Time: 2 years
