Thrombocytopenia and platelet apoptosis in patients with dengue infection or HIV plus dengue coinfection: (A) Prospective analysis of platelet counts at the febrile, defervescence and recovery phase of dengue illness in patients infected with dengue only or coinfected with HIV plus dengue (HIV + dengue); (B) The percentage of phosphatidylserine exposure measured by the binding of Annexin V on platelets from patients with dengue or HIV + dengue; (C) The fluorescence of the probe TMRE indicating the mitochondrial membrane potential (Δψm) in platelets from patients with dengue or HIV + dengue; and (D) The fluorescence of the probe FLICA indicating active caspase-9 in platelets obtained at acute and recovery phase from patients with dengue or HIV + dengue. The horizontal lines in the box plots represent the median, the box edges represent the interquartile ranges and the whiskers indicate 5–95 percentile. *Signifies p < 0.05 compared to patients with the same profile of infection (dengue or HIV + dengue) at the recovery.
