Decreased Docosahexaenoic acid levels in serum of HIV carrier patients

Abstract

The study aimed to measure serum fatty acids (FAs) composition in HIV carrier patients and compare it with non-HIV carrier patients. The FAs composition was measured by gas chromatography as follows: four saturated FAs myristic acid (14:0), palmitic acid (16:0), stearic acid (18:0), and docosanoic acid (22:0); four monounsaturated FAs 7-hexadecenoic acid (16:1 n-9), palmitoleic acid (16:1 n-7), oleic acid (18:1 n-9), and vaccenic acid (18:1 n-7); and three polyunsaturated FAs linoleic acid (18:2 n-6), dihomo-γ-linolenic acid (20:3 n-6), and docosahexaenoic acid (DHA, 22:6 n-3). We reported herein lower (P < .05) DHA concentration (by 40%) in the serum of HIV carrier patients than in non-HIV carrier patients. This FA has a pivotal role as a precursor of anti-inflammatory molecules with beneficial effects on metabolism, cardiovascular system, and immunological system. Even though most clinical studies reported beneficial effects of DHA supplementation in HIV carrier patients, this issue remains under debate. Further investigations then require to fully clarify the role of DHA in preventing or alleviating the comorbidities associated with HIV infection.
