title: Evaluation of a 6-year highly active antiretroviral therapy in Chinese HIV-1-infected patients.
abstract: OBJECTIVE
  To evaluate the long-term efficacy and tolerability of nevirapine (NVP)-based regimens in the treatment of human immunodeficiency virus (HIV)-infected Chinese patients in routine clinical practice.
  
  
  METHODS
  From October 2002 to May 2004, 57 HIV-1-infected patients commenced antiretroviral therapy (ART), and were followed up to December 2008. These antiretroviral-naïve patients, who originally received two nucleoside reverse transcriptase inhibitors and NVP, had HIV RNA levels, T lymphocyte subsets and safety parameters assessed over 6 years.
  
  
  RESULTS
  Of the 57 patients, 34 patients participated in the long-term follow-up. After 5-6 years, >60% of the patients had HIV RNA levels <50 copies/microl, and the median increase in CD4 cell counts from baseline was 329 cells/microl. gamma-Glutamyl transferase increased in 17 patients (29.8%); serum cholesterol and triglyceride levels were elevated in 15 patients (26.3%), and 25.0% (6/24) of the patients developed lipodystrophy (mainly females). Grade 3/4 adverse events occurred in 3 cases.
  
  
  CONCLUSIONS
  ART with NVP-based regimens suppressed HIV viremia and produced continued CD4 cell increases in a majority of subjects for 6 years. Safety and tolerance were good with no unexpected long-term toxicity. Though based on a small group, this study demonstrates durable effects of ART in Chinese patients.
