RESUMO
A descriptive, combined retrospective and prospective study was conducted at the Anonymous Clinic, Chon Buri Hospital, Chon Buri Province, Thailand from November 10, 2003 to January 4, 2004. A total of 83 adult HIV-treatment-naïve patients undergoing treatment with GPO-VIR (stavudine, lamivudine, and nevirapine) for at least one year were studied. The objectives of the study were to assess the efficacy of GPO-VIR by evaluating body weight changes, CD4 T-cell count changes, the occurrence of opportunistic infections, and long-term side effects, such as lipodystrophy, during treatment. Of 83 studied patients, approximately half (52.3%) of them had a body weight increase > 10% of pre-treatment body weight after 12 months treatment. After taking GPO-VIR, CD4 T-cell counts increased rapidly, by a median of 78 x 10(6) cells/l during the first three months. 39.5% of the patients attained median CD4 counts > 200 x 10(6) cells/I, and 11.6% achieved > 500 x 10(6) cells/l after 2 years of treatment. The occurrence of opportunistic infections was significantly lower after treatment with GPO-VIR (p = 0.001). Subjective assessment of lipodystrophy by physicians and patients showed that 16.8% had symptoms of lipodystrophy within 2 years of GPO-VIR treatment. There was a significant association between older age group (40-49 years) and occurrence of lipodystrophy (p = 0.043). GPO-VIR is an inexpensive and effective antiretroviral drug regimen for initiating treatment of naïve patients, but careful assessment for lipodystrophy is necessary, especially after one year of treatment.
