AIM To evaluate the impact of 3’UTR 3238C/G apoC-III variant on total cholesterol and TGs levels during HAART in HIV-infected children Studied subjects I) 82 HIV-infected children during a two-year period (2005-2006), with a median age of 140 mo (IQR: 122-160). All the children received HAART therapy with a median of 78 mo ( IQR: 67-83). II) 100 randomly collected blood donors were included to estimate genetic frequencies of the SNP in general population
* Percentages correspond to: (patients with ≥1 abnormal high determination)/(patients with ≥2 determinations) A higher proportion of abnormal high TGs and cholesterol levels was observed among homozygous CC
Odds ratios to abnormal TGs levels adjusted to Mixed-Effects logistic Model CG genotype showed a lower proportion of abnormal high TGs levels independent of time on HAART
Odds ratios to abnormal Cholesterol levels adjusted to Mixed-Effects logistic Model The model suggests that for short follow-up studies, the effect observed for the genotype on cholesterol levels would depend greatly on the cohort experience on HAART. A increasing risk of abnormal high cholesterol was observed for the CC genotype
CONCLUSIONS • Heterozygotes 3238 C/G had fewer events of abnormal high cholesterol, with a more prominent effect when HAART was received for long periods. • Heterozygotes 3238 C/G also showed fewer events of abnormal high triglycerides, independently of time on HAART. Our results suggest a protective effect of the 3'URT 3238C/G genotype of ApoC-III on the development of PI- related dyslipemia in HIV-infected children
