RESUMO
The clinical course of COVID-19 in patients undergoing chronic immunosuppressive therapy is yet poorly known. We performed a monocentric cross-sectional study describing the clinical course of COVID-19 in a cohort of patients from northern Italy treated with calcineurin-inhibitors for organ transplantation or rheumatic diseases. Data were collected by phone call and clinical chart review between March 27th- 31st 2020. COVID-19 related symptoms, rynopharingeal swab, therapeutic changes and outcome were assessed in 384 consecutive patients (57% males; median age 61 years, IQR 48-69). 331 patients (86%) received solid organ transplantation (kidney n=140, 36%, heart n=100, 26%, lung n=91, 24%) and 53 (14%) had a rheumatic disease. Calcineurin inhibitors were the only immunosuppressant administered in 46 patients (12%). 14 patients developed a "confirmed COVID-19" (swab positivity) and 14 a "clinical COVID-19" (only typical symptoms). Fever (75%) and diarrhoea (50%) were the most common symptoms. Fourteen patients were hospitalized and 11 have already been dismissed. No patient required start/changes of the O2 therapy or developed superinfection. Only one patient, with metastatic lung cancer, died. In conclusion, COVID-19 showed a mild course in our cohort, with low mortality. Calcineurin inhibitor-based immunosuppressive regimens appear safe in this context and should not be discontinued.
