Retrospective 2,882 patients in China, median age 62, 278 receiving HC
Q, median 10 days post hospitalization, showing that HC
Q treatment can reduce systemic inflammation and inhibit the cytokine storm, thus protecting multiple organs from inflammatory injuries, such as detoxification in the liver and attenuation of cardiac injury. IL-6 levels significantly reduced after HC
Q treatment, p<0.05, and elevated after HC
Q withdrawal. The significantly lower dose used here is potentially related to the different observations from the RECOVERY trial results. Authors suggest that treatment should be started as soon as possible.
