Detailed Description
The PLATFORM trial is a single-center, open-label randomized controlled trial of whole blood transfusion for severe malaria complicated by thrombocytopenia. The trial will recruit 132 Zambian children 6 months to 15 years old with severe malaria defined according to modified WHO criteria with concomitant thrombocytopenia, defined here as a platelet count ≤75,000/uL, who do not otherwise have a current indication for transfusion according to current guidelines. Children will be randomized 1:1 to whole blood transfusion or no whole blood transfusion and followed to hospital discharge or death. The trial is nested within the Children and Adults with Severe Malaria (CHASM) cohort, a prospective observational study of severe malaria.

Outcome Measures
Primary Outcome Measures
- Incidence of all-cause mortality [Up to hospital discharge or in-hospital death, up to 28 days on average]
Death due to any cause
Secondary Outcome Measures
- Change in hemoglobin (Hb) [Pre- and post-transfusion, comparing baseline measurements to measurements taken 2 hours after transfusion completion and 24 hours later. For the Control arm, measurements will be made at baseline and Study Hour 6 ±2 and 24 hours later]
The difference in Hb concentration between baseline (pre-transfusion) and post-transfusion
- Change in platelet count [Pre- and post-transfusion, comparing baseline measurements to measurements taken 2 hours after transfusion completion and 24 hours later. For the Control arm, measurements will be made at baseline and Study Hour 6 ±2 and 24 hours later]
The difference in the platelet count between baseline (pre-transfusion) and post-transfusion
- Change in white blood cell (WBC) count [Pre- and post-transfusion, comparing baseline measurements to measurements taken 2 hours after transfusion completion and 24 hours later. For the Control arm, measurements will be made at baseline and Study Hour 6 ±2 and 24 hours later]
The difference in the WBC count between baseline (pre-transfusion) and post-transfusion
- Incidence of transfusion reaction [During or after transfusion, up to the day of hospital discharge or in-hospital death, up to 28 days on average]
Transfusion reactions (e.g., hypersensitivity, TACO, TRALI) graded on severity and likeliness of being related to transfusion
- Length of hospitalization [Up to hospital discharge or in-hospital death, up to 28 days on average]
Interval in days from date of admission to date of discharge/death
- Parasite clearance [0-72 hours, measured every 12±2 hours]
Time to microscopic conversion to negative
