The impact of malaria on common lipid parameters

No data are available in the literature to indicate whether low-level Plasmodium falciparum infections induce lipid parameter changes. We hypothesized that low-level P. falciparum infections induce significant changes in common lipid parameters. We retrospectively selected samples from a malaria prophylaxis study to measure the impact of sustained parasite clearance on common lipid parameters [total cholesterol (TChol), high-density lipoprotein (HDL)-cholesterol (HDL-c), low-density lipoprotein (LDL)-cholesterol (LDL-c) and triglycerides (TG)] in 47 apparently healthy schoolchildren whose P. falciparum parasitemia was initially below 1000/μl. After parasite clearance, mean values were significantly increased for Tchol (P < 0.001) and HDL-c (P < 0.001), unlike LDL-c (P = 0.93); and TG were significantly decreased from the baseline (P = 0.004). No significant change was found in a control group. This is the first study showing significant lipid changes related to low-level P. falciparum infections. Further studies are needed to explore the relevance of this finding at the population level in hyperendemic malaria areas.
