He had no bleeding manifestations and had a good response to prednisone treatment.We review the characteristics of the cases reported to date in the literature, with an analysis of 57 patients. Mean age was 56 years (±19.6 SD), and 50.9% were male. This was the first episode of ITP in most of the patients (86.05%), with SARS-CoV-2 acting as the initial trigger. We found that ITP flares may appear in both mild and severe COVID-19 cases. They also appeared at any time during the course of the disease, 48.2% of patients developed it during hospitalization, while it was diagnosed at admission in the rest of the cases. Platelet counts were significantly lower than other ITP series, with a median nadir platelet count of 8 × 109/L (IQR 2-17.75 × 109/L). These patients show a higher bleeding rate (61.4%) compared with other ITP series. They also show a better response to treatment, with good response to the first line therapies in 76.9% of them. The most common first-line treatment was intravenous immunoglobulin (IVIG), used alone or combined with corticosteroids in 40.4% and 32.7% of cases respectively, while 25% of patients received only corticosteroids.Our review suggests that COVID-19-related ITP can be seen even in previously healthy patients. Clinicians must be aware that ITP may appear both in mild and severe COVID-19, at any time during its course. Given that this kind of ITP seems to be associated with a higher bleeding risk, its diagnosis in a clinical scenario such as COVID-19, where anticoagulant therapy is frequently used, may be critical. Treatment with IVIG and/or corticoids is often effective. PB Sage Publications Ltd.
