Prospective analysis of early treatment of 350 patients in Italy (without waiting for PCR results), showing low hospitalization rates and no serious adverse events.
From 274 patients treated with HCQ, 16 required hospitalization (5.8%). Minor complications (mainly gastrointestinal, diarrhoea) were found in eight patients (2.9%), none of whom had to interrupt treatment. No major cardiac complications were found.
Of the 76 patients treated with HCQ+AZ, 4 were hospitalized (5.2%). Minor complications occurred in two patients (2.6%). There were no reports of any major arrhythmias, syncope or sudden death.
