Critically ill patients present a similar or even stronger immunity against the virus than convalescent patients. This supports the theory that severe infections might be linked to an exaggerated immune reaction.
A weak immune response isn’t the cause of dangerous lung failure in severe Covid-19 infections. Such infections seem, on the contrary, to be caused by an overreaction of the immune system. This is the conclusion made by a research team from Ruhr-Universität Bochum (RUB) and the university hospital of Duisburg-Essen led by Professor Nina Babel, Head of the Centre for Translational Medicine at the RUB clinic Marien Hospital Herne. The team from Marien Hospital and the department of Virology of Ruhr-Universität Bochum (RUB) as well as the Clinic for Infectious Diseases, the Clinic of Anesthesiology and the Institute for Virology of University Medicine Essen studied specific antibodies and T cells occurring in recovered, seriously ill and deceased Covid-19 patients. The researchers identified comparable immune reactions in clinical follow up. They report their findings in the journal Cell Reports Medicine from 29 August 2020.
