Changes in serum lipid profile in the acute and convalescent Plasmodium vivax malaria: A cohort study.
2016
Abstract Although serum lipids are known to be altered in Plasmodium falciparum -induced malaria, little is known about such changes due to Plasmodium vivax infection. This cohort study assessed serum concentrations of triglycerides, total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) in 164 patients in the acute phase of malaria caused by P. vivax and characterized these changes in the convalescent phase after treatment with chloroquine and primaquine. Compared to reference values, serum total cholesterol, LDL, and HDL levels were lower and triglyceride levels were higher in the acute phase. Moreover, the parasite density was negatively correlated with LDL (r = −0,189; p = 0.027) and HDL (r = −0,256; p = 0.001) serum levels. Eighty patients returned for clinical and laboratory revaluation 7–12 days after treatment initiation. All patients showed parasite clearance and the absence of symptoms during the convalescent phase. Analysis of the serum lipids of these 80 patients showed significant increases in the serum levels of total cholesterol ( p p p p = 0.004), indicating a trend towards a return to normal levels. This transient change in lipid profile between the acute and convalescent stages may be useful for the clinical monitoring of patients treated for vivax malaria.
