We experimentally demonstrate for the first time that artemisinin resistance provides a fitness advantage that is selected for with infrequent exposure to drug, but is lost in the absence of exposure to artemisinin drugs.

The clinical implications of thrombocytopenia in adults with severe falciparum malaria: a retrospective analysis

April 28, 2015 - 16:44 -- Open Access
Author(s): 
Hanson J, Phu N, Day N, et al.
Reference: 
BMC Medicine 2015, 13 :97 (24 April 2015)

The 39 patients (6%) with profound thrombocytopenia (platelet count <20 × 109/L) were more likely to die (odds ratio: 5.00, 95% confidence interval: 2.56 to 9.75) than patients with higher platelet counts, but these high-risk patients could be identified more rapidly with simple bedside clinical assessment. The admission platelet count did not reliably identify the 50 patients (7.7%) with major bleeding during the study.
