Baseline characteristic
We screened 3,255 hospitalized COVID-19 patients and identified 30
patients with chronic ITP and had been admitted to the hospital. Of all
patients, eighteen (60%) were male, and the median age was 68 year old
(IQR: 64-77). Hypertension (73%) and diabetes (50%) were the most
common comorbidities. At the time of COVID-19 diagnosis, nine (30%)
patients had an active malignancy and three (10%) patients had a
history of autoimmune diseases which were SLE, Takayasu arteritis, and
Hashimoto’s thyroiditis. Shortness of breath and fever were the main
reasons for hospital presentation; 50%, and 30% respectively. The
median platelet count at the time of admission was 120 x
109/L (IQR: 110-166). Of all patients, only six (20%)
were admitted to ICU and four (13.3%) required mechanical ventilation.
None of the patients had bleeding at the time of admission or had a
splenectomy in the past.
