Immune thrombocytopenia, also known as immune thrombocytopenic purpura (ITP), has been reported as an important complication related to COVID-19. We present a 49-year-old male patient with systemic lupus erythematosus with lupus nephritis, antiphospholipid syndrome and history of ITP who developed an ITP flare in the context of COVID-19. 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.

Coronavirus disease 2019 (COVID‐19) infection in elderly patients is more aggressive and treatments have shown limited efficacy. Our objective is to describe the clinical course and to analyze the prognostic factors associated with a higher risk of mortality of a cohort of patients older than 80 years. In addition, we assess the efficacy of immunosuppressive treatments in this population. We analyzed the data from 163 patients older than 80 years admitted to our institution for COVID‐19, during March and April 2020. A Lasso regression model and subsequent multivariate Cox regression were performed to select variables predictive of death. We evaluated the efficacy of immunomodulatory therapy in three cohorts using adjusted survival analysis. The mortality rate was 43%. The mean age was 85.2 years. The disease was considered severe in 76.1% of the cases. Lasso regression and multivariate Cox regression indicated that factors correlated with hospital mortality were: age (hazard ratio [HR] 1.12, 95% confidence interval [CI]: 1.03–1.22), alcohol consumption (HR 3.15, 95% CI: 1.27–7.84), CRP > 10 mg/dL (HR 2.67, 95% CI: 1.36–5.24), and oxygen support with Venturi Mask (HR 6.37, 95% CI: 2.18–18.62) or reservoir (HR 7.87, 95% CI: 3.37–18.38). Previous treatment with antiplatelets was the only protective factor (HR 0.47, 95% CI: 0.23–0.96). In the adjusted treatment efficacy analysis, we found benefit in the combined use of tocilizumab (TCZ) and corticosteroids (CS) (HR 0.09, 95% CI: 0.01–0.74) compared to standard treatment, with no benefit of CS alone (HR 0.95, 95% CI: 0.53–1.71). Hospitalized elderly patients suffer from a severe and often fatal form of COVID‐19 disease. In this regard, several parameters might identify high‐risk patients upon admission. Combined use of TCZ and CS could improve survival.
