This study examined the impact of L-acetylcarnitine treatment on metabolic parameters and body composition in patients with lipodystrophy syndrome secondary to antiretroviral treatment in human immunodeficiency virus (HIV) infection. A total of 9 HIV-1 infected patients with lipodystrophy syndrome (4F/5M, age 41+/-5 years, HIV duration 8+/-2 years, BMI 23.7+/-3.4 kg/m (2), on protease inhibitors and nucleoside analogue Reverse Transcriptase inhibitors) were evaluated before and after 8 months of therapy with L-acetylcarnitine (2 g/die) and 9 matched healthy subjects served as control subjects. In all patients fasting plasma glucose, insulin concentrations (for evaluation of surrogate indexes of insulin sensitivity), lipid profile, lipid oxidation (by indirect calorimetry), body composition (by DEXA), and intramyocellular triglyceride (IMCL) content of the calf muscles (by (1) H NMR spectroscopy) were assessed. After this therapy, in HIV-1 patients, the IMCL content of the soleus had significantly decreased (p=0.03). Plasma FFAs (0.79+/-0.31 to 0.64+/-0.25; p<0.05) and Respiratory Quotient (0.83+/-0.18 to 0.72+/-0.16; p<0.03) also decreased. Insulin sensitivity was significantly lower prior (HOMA-IS 0.56+/-0.30) and nonstatistically different than controls after therapy (0.72+/-0.49 vs. 0.78+/-0.42) whilst the percentage of fat in the legs increased (p=0.05). Eight months of L-acetylcarnitine treatment increased lipid oxidation, decreased intramyocellular triglyceride content, and induced a more physiological distribution of fat deposits.
