Background: Changes in lipid profile are seen in many patients infected with malaria parasite. The malaria parasite causes hepatocellular damage and disturbs lipid handling by the liver. Inside hepatocytes and erythrocytes the parasite replicates rapidly scavenging cholesterol and lipids required for its growth and metabolism from the host. It also requires host lipids for detoxification of free heme to form the malarial pigment, haemozoin. The important question is whether these changes are characteristic for malaria infection or are they simply part of an acute phase reaction? This study analyzes the correlation between malaria infection and derangements in lipid profiles.

Materials and Methods: This study comprised of 29 confirmed malaria cases, and 29 subjects in apparent good health, without the infection were included as control cases. Malaria cases were confirmed using rapid antibody-based diagnostic card tests that detect histidine-rich protein 2 (HRP2) or lactate dehydrogenase antigens in finger-prick blood samples followed by microscopic confirmation of malaria parasite. A 12 -hour fasting lipid profile was estimated by enzymatic method on day 2. Data obtained were statistically analyzed using Student’s t Test, assuming p<0.05 as significant. All issues related to ethics were taken care of during the whole course of study.

Results: As compared with control subjects, patients with malaria showed low HDL (16.48±6.490 mg/dL versus 41.38±15.110 mg/dL), low LDL (70.45±22.720 mg/dL versus 104.46±27.353 mg/dL), low cholesterol (103.52±35.331 mg/dL versus 169.45±34.040 mg/dL) and elevated triglycerides (214.24±109.365 mg/dL versus 131.15±30.813 mg/dL). The observations show a statistically significant difference in HDL, LDL, cholesterol and triglycerides between malaria patients and control subjects (p<0.05).

Conclusion: These results show a characteristic pattern of derangements of lipid profile in malaria. Further studies are required to understand the diagnostic, prognostic and therapeutic implications of these derangements.
