Insights
Plasmodium falciparum malaria infection significantly lowers apolipoprotein-A1 and cholesterol levels in children. These lipid alterations, particularly reduced apolipoprotein-A1, correlate with malaria severity, offering potential diagnostic insights.
Area of Science:
- Biochemistry
- Infectious Diseases
- Pediatrics
Background:
- Malaria, caused by Plasmodium falciparum, is a significant global health concern, especially in young children.
- Lipid metabolism and apolipoprotein-A1 play crucial roles in health and disease, but their specific alterations in pediatric malaria are not fully understood.
Purpose of the Study:
- To investigate the impact of Plasmodium falciparum malaria on serum apolipoprotein-A1 and cholesterol levels in children under five.
- To determine if apolipoprotein-A1 levels correlate with the severity of malaria infection in this age group.
Main Methods:
- A case-control study involving 255 children: 170 with P. falciparum malaria (85 uncomplicated, 85 complicated) and 85 healthy controls.
- Serum levels of apolipoprotein-A1, total cholesterol, HDL, LDL, and triglycerides were measured and compared using ANOVA and post hoc analyses.
Main Results:
- Children with malaria (both uncomplicated and complicated) exhibited significantly lower mean serum levels of apolipoprotein-A1, total cholesterol, and LDL compared to healthy controls.
- While both malaria groups showed reduced lipid levels, the reductions were more pronounced in children with complicated malaria.
- No significant difference in lipid levels was observed between the uncomplicated and complicated malaria groups themselves, but the severity of reduction was worse in complicated malaria.
Conclusions:
- Altered serum lipid profiles, characterized by reduced apolipoprotein-A1, are associated with complicated malaria in children.
- These findings suggest that apolipoprotein-A1 and lipid level alterations may hold diagnostic utility in managing pediatric malaria.
Objective:
This study was carried out to determine whether or not Plasmodium falciparum malaria infection significantly affected apolipoprotein-A1 and cholesterol levels and if apolipoprotein-A1 correlated with the malaria severity in children younger than 5 years old.
Subjects And Methods:
Two hundred and fifty-five children, 170 of whom had microscopically confirmed P. falciparum infection, i.e. 85 cases of uncomplicated malaria (UM) and 85 of complicated malaria (CM), and 85 healthy controls were enrolled in this study. Serum levels of apolipoprotein-A1, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglycerides were determined. These levels were compared among the malaria and control groups, using ANOVA and post hoc analyses at p = 0.05.
Results:
There were significant differences in the mean serum levels of apolipoprotein-A1 (UM: 104.5 ± 38.1 mg/dl, CM: 90.9 ± 33.3 mg/dl and controls: 129.7 ± 48.3 mg/dl; p < 0.001), total cholesterol (UM: 138.8 ± 62.9 mg/dl, CM: 121.2 ± 55.2 mg/dl and controls: 155.1 ± 69.8 mg/dl; p = 0.002) and LDL (UM: 98.2 ± 55.5 mg/dl, CM: 84.3 ± 47.4 mg/dl and controls: 122.7 ± 69.4 mg/dl; p < 0.001). Post hoc analyses revealed that children with UM and CM had significantly lower levels of apolipoprotein-A1, cholesterol, HDL and LDL than controls but that there was no difference between the 2 malaria groups. Reductions in levels of lipids and apolipoprotein-A1 were worse in CM than in UM.
Conclusion:
Altered levels of serum lipids with CM were associated with a reduction in apolipoprotein-A1. These findings have potential diagnostic utility for the management of malaria.
