Red Blood Cell Exchange Transfusion for Severe Babesiosis This multicenter cohort study evaluates whether red blood cell exchange transfusion improves clinical outcomes among hospitalized adult patients with severe babesiosis.

Retrospective multicenter of severe babesia in 🇺🇸between 2010-2024

Despite higher parasitemia (14.0% vs 7.2%), the 1/3 that got exchange transfusion within 7 days had lower composite 30 day mortality and readmission (aOR, 0.22; 95% CI, 0.09-0.51)
