Immune thrombocytopenia and COVID-19 vaccination: Outcomes and comparisons to prepandemic patients.

ABSTRACT:

Background

Immune thrombocytopenia (ITP) has been reported following COVID-19 vaccination. After index case fatalities, there was concern among patients both with and without a prior history of ITP in Australia.

Objectives

To describe treatment outcomes of ITP after COVID-19 vaccination and compare relapsed vs historical pre-COVID-19 ITP cohorts.

Methods

We collected ITP cases in Australia within 6 weeks of receiving any COVID-19 vaccination as part of primary vaccination (up to October 17, 2021). Second, we reviewed platelet charts in a historical ITP cohort to determine whether platelet variability was distinct from relapsed ITP after vaccination.

Results

We report on 50 patients (37 de novo, 13 relapsed ITP) vaccinated from March 22, 2021, to October
