Официальное название
Clinical and Translational Investigations of Severe Malaria Pathophysiology [Parent Study Protocol]
Обзор
Open-label randomized controlled trial to test the effectiveness of whole blood transfusion for improving survival in children with severe malaria complicated by thrombocytopenia.
Подробное описание
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.

- Change in platelet count [Срок оценки: 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]
- Change in white blood cell (WBC) count [Срок оценки: 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]
- Incidence of transfusion reaction [Срок оценки: During or after transfusion, up to the day of hospital discharge or in-hospital death, up to 28 days on average]
- Length of hospitalization [Срок оценки: Up to hospital discharge or in-hospital death, up to 28 days on average]
- Parasite clearance [Срок оценки: 0-72 hours, measured every 12±2 hours]
