Some Covid Survivors Have Antibodies That Attack the Body, not Virus
New research found autoantibodies similar to those in lupus and rheumatoid arthritis patients. But patients may also benefit from treatments for those autoimmune diseases.

Covid-19 patients were discharged from a temporary hospital in Lima, Peru, last month. The study may help explain why so-called long-haulers continue to experience symptoms long after the virus has left their bodies.Credit...

Some survivors of Covid-19 carry worrying signs that their immune system has turned on the body, reminiscent of potentially debilitating diseases like lupus and rheumatoid arthritis, a new study has found.
At some point, the bodys defense system in these patients shifted into attacking itself, rather than the virus, the study suggests. The patients are producing molecules called autoantibodies that target genetic material from human cells, instead of from the virus.
This misguided immune response may exacerbate severe Covid-19. It may also explain why so-called long haulers have lingering problems months after their initial illness has resolved and the virus is gone from their bodies.
The findings carry important implications for treatment: Using existing tests that can detect autoantibodies, doctors could identify patients who might benefit from treatments used for lupus and rheumatoid arthritis. There is no cure for these diseases, but some treatments decrease the frequency and severity of flare-ups.
Its possible that you could hit the appropriate patients harder with some of these more aggressive drugs and expect better outcomes, said Matthew Woodruff, an immunologist at Emory University in Atlanta and lead author of the work.
The results were reported Friday on the preprint server MedRxiv, and have not yet been published in a scientific journal. But other experts said the researchers who carried out the study are known for their careful, meticulous work, and that the findings are not unexpected because other viral illnesses also trigger autoantibodies.
