Events of Immune Thrombocytopenic Purpura (ITP) Among COVID-19-positive Adults in the United States; an Analysis via the National Inpatient Sample for Cases Between April to November 2020 (preprint)

ABSTRACT

Various cases of immune thrombocytopenic purpura (ITP) were reported among COVID-19-positive patients in the literature. We used the National Inpatient Sample (NIS) to evaluate the odds of ITP among COVID-19 patients in the United States between April and November 2020. Females (vs. Males), Whites (vs. other races), and the presence of multiple comorbidities such as chronic kidney disease, cirrhosis, prior stroke, HIV, obesity, cachexia, neoplasms, and autoimmune conditions showed higher odds of ITP. Meanwhile, those with diabetes and peripheral vascular disease and covered by private insurance (vs. Medicare) were less likely to experience ITP while being positive for the virus. Events of ITP also led to a higher mortality risk in COVID-19-positive patients.
