Abstract
Background
The study was done to assess high-density lipoprotein (HDL) functionality and to correlate this with paraoxonase 1 (PON1) activity in malnourished children. It aimed to find the effect of malnutrition on changes in PON1 activity, HDL functionality, lipid profile and lipid hydroperoxide formation.
Methods
This case control study included 30 malnourished children (up to age 5 years) and 30 healthy controls in the paediatric inpatient department of SRTR Government Medical College Ambajogai, India. Clinically diagnosed cases depending on anthropometric indices were selected. Serum PON1 activity by using phenyl acetate as a substrate, HDL functionality by haemin by its protection on H2O2 and haemin induced LDL oxidation, lipid profile by routine enzymatic methods and lipid hydroperoxide using the FOX2 assay were measured.
Results
Malnourished children had significantly decreased PON1 activity (106.6 ± 12.74** vs. 132.23 ± 28.49 IU/L), HDL functionality (116.55 ± 8** vs. 132.29 ± 10.9%), total cholesterol (TC) (102.5 ± 16** vs. 116.4 ± 12.65 mg/dL), HDL-cholesterol (C) (33.41 ± 9.74** vs. 40.55 ± 5.85 mg/dL) and reduced total protein level (5.56 ± 0.91* vs. 6.06 ± 1.055) higher triglycerides (TG) (146.76 ± 34.97* vs. 125.96 ± 17.21 mg/dL) level and total hydroperoxide (TPX) levels (5.568 ± 1.70** vs. 3.22 ± 1.52 μM/L). *p < 0.05 **p < 0.001. PON1 activity (r2 = 0.576) and TC (r2 = 0.567) shows significant positive correlation with HDL functionality. PON1 activity, HDL-C, HDL functionality and TPX shows independent contribution towards malnutrition in children in multivariate and univariate logistic regression. TC lost its significance in multivariate regression.
Conclusions
Malnutrition leads to decrease in HDL functionality and increase in hydroperoxide levels with a decrease in PON1 activity.
