We screened 3,255 hospitalized COVID-19 patients and identified 30 patients with chronic ITP admitted to the hospital. Of all patients, only six (20%) were admitted to ICU. None of the patients had bleeding at the time of admission. During hospitalization, 13 (43.3%) patients developed ITP relapses. Five (38.5%) patients developed six bleeding complications, None of the bleeding events was major. Of all patients treated for ITP relapses, three patients (23%) showed complete response after different steroid treatment regimens. None of our relapsed patients required IVIG. Among patients who were treated conservatively, complete response achieved in 50% (4/8) and partial response achieved in 12.5% (1/8). Overall, seven (23.3%) death events happened. The main cause of death in all patients was acute hypoxic respiratory failure. Five (71.4%) out of the total patients who died had ITP relapses.
