(Reuters) - The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.

Coronavirus leaves survivors with self-attacking antibodies

Months after recovering from SARS-CoV-2 infection, survivors have elevated levels of antibodies that can mistakenly attack their own organs and tissues, even if they had not been severely ill, according to new findings.

Among 177 healthcare workers who had recovered from confirmed coronavirus infections contracted before the availability of vaccines, all had persistent autoantibodies, including ones that can cause chronic inflammation and injury of the joints, skin and nervous system. "We would not normally expect to see such a diverse array of autoantibodies elevated in these individuals or stay elevated for as long six months after full clinical recovery," said Susan Cheng of the Cedars-Sinai Smidt Heart Institute in Los Angeles. Patterns of elevated autoantibodies varied between men and women, the researchers reported on Thursday in the Journal of Translational Medicine .
