Association between treatment with colchicine and improved survival in a single-centre cohort of adult hospitalised patients with COVID-19 pneumonia and acute respiratory distress syndrome.

The outbreak of COVID-19 posed the issue of urgently identifying treatment strategies. Colchicine was considered for this purpose based on well-recognised anti-inflammatory effects and potential antiviral properties. In the present study, colchicine was proposed to patients with COVID-19, and its effects compared with 'standard-of-care' (SoC). In the public hospital of Esine, northern Italy, 140 consecutive inpatients, with virologically and radiographically confirmed COVID-19 admitted in the period 5-19 March 2020, were treated with 'SoC' (hydroxychloroquine and/or intravenous dexamethasone; and/or lopinavir/ritonavir). They were compared with 122 consecutive inpatients, admitted between 19 March and 5 April 2020, treated with colchicine (1 mg/day) and SoC (antiviral drugs were stopped before colchicine, due to potential interaction). Patients treated with colchicine had a better survival rate as compared with SoC at 21 days of follow-up (84.2% (SE=3.3%) This proof-of-concept study may support the rationale of use of colchicine for the treatment of COVID-19. Efficacy and safety must be determined in controlled clinical trials.
