Objectives 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). Methods 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). results Patients treated with colchicine had a better survival rate as compared with soC at 21 days of followup (84.2% (se=3.3%) vs 63.6% (se=4.1%), p=0.001). Cox proportional hazards regression survival analysis showed that a lower risk of death was independently associated with colchicine treatment (HR=0.151 (95% Ci 0.062 to 0.368), p<0.0001), whereas older age, worse PaO2/FiO2, and higher serum levels of ferritin at entry were associated with a higher risk. Conclusion 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. Key messages What is already known about this subject? ► Considering the hypothesis that COVID-19 in its worst manifestations resembles a secondary, viral-driven haemophagocitic lymphohistiocytosis syndrome, a rationale for the use of antirheumatic drugs that are used for autoinflammatory disease have been placed in the algorithm of treatment. What does this study add? ► Based on anti-inflammatory and potential antiviral properties, colchicine was administered to hospitalised patients with COVID-19 pneumonia and acute respiratory distress syndrome (ARDS). ► The survival rate of patients treated with colchicine was significantly higher as compared with that of patients treated with standard of care only (84.2% vs 63.6%). How might this impact on clinical practice or future developments? ► This proof-of-concept study supports the rationale of testing colchicine in clinical trials for the treatment of COVID-19 pneumonia with ARDS.
Epidemiology FiO 2 , lower CRP, ferritin and neutrophil count). Indeed, Cox proportional hazards regression survival analysis showed the independent association of colchicine treatment with survival and that of older age, higher serum levels of ferritin and more severe hypoxaemia at admission with death. In conclusion, our report can be considered as a proof-ofconcept study supporting the possible use of colchicine in the treatment of the early phase of COVID-19 with the purpose of preventing the host's autoinflammatory response. Properly designed trials will determine the efficacy and safety of colchicine and the best protocol in terms of dosage and timing of administration in patients with COVID-19. Such trials have been approved in Greece, 18 Italy 19 and Canada. 20 Author affiliations Contributors all authors were involved in drafting the article or revising it critically for intellectual content.
