Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. In-hospital mortality 2. 30 day mortality 3. Neurological outcome at day 30 4. Safety Primary endpoints will be mortality and neurological state at baseline and discharge from hospital | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Parasite clearance time 2. Clinical and biochemical measures (see below). 3. Biochemical and hemodynamic measures at the start and completion of therapy will also be compared 4. Area under the curve for microvascular reactivity by reactive hyperemia-peripheral artery tonometry (RH-PAT) [0-25 hrs] 5. Endothelial function [near-infrared reflectance spectroscopy (NIRS) and RH-PAT] 6. Lactate clearance 7. Improvement in microvascular obstruction [Orthogonal Polarization Spectral (OPS) imaging] 8. Change in tissue oxygen consumption (measured by NIRS occlusion phase) 9. Change in NO production 10. Change in red cell deformability 11. Changes in CSF markers of neuronal and axonal damage and astroglial activation | — |
