To evaluate the influence of long-term nucleotide reverse transcriptase inhibitors (NRTIs) on lipids metabolism in HIV/AIDS patients and correlating clinical factors.A total of 118 HIV/AIDS patients were divided into 3 groups: untreated group (40 patients), highly active antiretroviral therapy (HAART) for 1 - 2 years group (37 patients) and HAART over 5 years group (41 patients), with 20 healthy individuals as the control group. Clinical lipodystrophy (LD) was defined as concordance between patient's report of change and physical examination. Fat mass (FM) was measured by dual-energy X-ray absorptiometry (DXA).There was no significant difference in the incidence of LD between HAART for 1 - 2 years group and HAART over 5 years group (51.2% vs 40.5%, P = 0.345). The prevalence of LD was 2.4 folds with stavudine (d4T) treatment compared with zidovudine (AZT)-containing regimens (61.6% vs 23.5%, P = 0.001). Based on DXA measurements, FM of total body and limbs were significantly lower in the HAART over 5 years group than that in the control group, the untreated group and the HAART for 1 - 2 years group (P0.05). Trunk FM was significantly lower in the HAART over 5 years group than the untreated group and the HAART for 1 - 2 years group (P0.05). FM of total body and trunk were significantly lower in patients without LD in the HAART over 5 years group than patients without LD in the HAART for 1 - 2 years group (P0.05). FM was correlated positively with body weight and BMI. Limbs FM was correlated negatively with peripheral blood triglyceride concentration.HIV/AIDS patients with NRTIs therapy have high prevalence of LD, which mainly occurs 1 - 2 years after therapy, and increases with d4T treatment compared with AZT-containing regimens. There was no significant difference in the incidence of LD between the HAART for 1 - 2 years group and the HAART over 5 years group. FM was significantly decreased after long-term HAART in the patients with or without LD. DXA can evaluate LD objectively and guide further clinical treatment.
