Abstract
Summary Background The global pandemic of COVID-19 cases caused by infection with SARS-CoV-2 is ongoing. We describe here the clinical course of COVID-19 in a cohort of confirmed cases in Wuhan, China, treated with the repurposed potential experimental therapeutics IFN-α2b, arbidol or a combination of IFN-α2b plus arbidol. Methods 77 adults with confirmed COVID-19 were treated with either nebulized IFN-α2b (5mU,b.i.d.), arbidol (200mg dispersible tablet, t.i.d.) or a combination of IFN-α2b plus arbidol. Serial SARS-CoV-2 testing along with hematological measurements, including cell counts and blood biochemistry, serum cytokine levels, temperature and blood oxygen saturation levels were recorded for each patient during their hospital stay. Findings Treatment with IFN-α2b with or without arbidol significantly reduced the duration of detectable virus in the upper respiratory tract and in parallel reduced duration of elevated blood levels for the inflammatory markers IL-6 and CRP. Interpretation IFN-α2b should be investigated as therapy in COVID-19 cases.
