Increased trunk fat along with decreased peripheral fat as an important predictor of hypertriglyceridaemia & hypercholesterolaemia in Indians with HIV infection

Background & objectives: Dyslipidaemia is a major contributor to cardiovascular morbidity, which is increased in HIV. Data on dyslipidaemia in Indians with HIV are scant. This study was undertaken to determine the predictors of dyslipidaemia and lipoatrophy in Indians with HIV infection and their relation with body composition parameters. Methods: A total of 382 consecutive patients with HIV infection were screened, of whom 257 clinically stable patients, without any acute comorbidity, having at least one year follow up underwent biochemical and DEXA analysis. Results: The most common dyslipidaemia was hypertriglyceridaemia (47.08%), followed by hypercholesterolaemia [total cholesterol (TC)] (38.91%) and low high-density lipoprotein (HDL) cholesterol (38.52%), in patients having median age 37 (32-42) yr and HIV duration 57 (33-101) months. Patients with at least one dyslipidaemia (78.99%) had significantly higher insulin resistance (IR), per cent body fat, per cent trunk fat (PTF) and trunk limb fat ratio (TLFR). Baseline CD4 count and delta CD4 count (change in CD4 count 6-12 months following ART) had significant inverse correlation with triglycerides and TC. Patients with highest triglycerides and cholesterol quartiles had significantly higher immune reconstitution, metabolic syndrome, IR, trunk fat mass (FM), PTF and TLFR, with comparable total FM. Logistic regression revealed that body mass index, HIV duration and PTF were independent predictors of hypertriglyceridaemia, with only PTF being significant predictor of hypercholesterolaemia. Every unit increase in PTF was associated with 13 and 4.1 per cent increased hypertriglyceridaemia and hypercholesterolaemia. Lipoatrophy was present in 8.57 per cent patients and was a poor predictor of dyslipidaemia. Interpretation & conclusions: High occurrence of dyslipidaemia was observed in patients with HIV on anti retroviral therapy. Central adiposity (TFM) was the most important predictor of dyslipidaemia in these patients.
