Objective: To evaluate the therapeutic effect of highly active anti-retroviral therapy (HAART) in treatment-naïve Chinese patients with AIDS, to provide evidences for standardizing HAART.
Methods: Seventy-four treatment-naive AIDS patients were initiated with HAART and followed up regularly for 3 years. The clinical and laboratory data, side effects and drug resistance were observed and analyzed during the follow-up period.
Results: Of the 74 patients, 46 were males and 28 were females, with the average age being 42 years. The mean HIV viral load was (2.2 ± 2.0) × 10(5) copies/ml and the baseline mean CD(4)(+)T lymphocyte count was (62 ± 71) cells/µl before treatment. After treatment for 3, 6, 12, 18, 24, 30 and 36 months, the percentage of undetectable HIV viral road (less than 50 copies/ml) was 71.6%, 83.8%, 75.7%, 77.0%, 82.4%, 81.1% and 79.7% respectively, and CD(4)(+)T lymphocyte count ascended to (167 ± 105), (177 ± 129), (238 ± 137), (290 ± 158), (304 ± 191), (331 ± 175) and (352 ± 202) cells/µl. The increase in amplitude of CD(4)(+)T lymphocyte count in different periods examined was different, with the period of 0-3 months post-treatment demonstrating the most obvious augmentation (P < 0.01). The most common adverse reactions were liver function injury (52/74, 70.3%), hyperlipemia (52/74, 70.3%), hematopoietic inhibition of the bone marrow (33/74, 44.6%), peripheral neuritis (32/74, 43.2%) and lipoatrophy (26/74, 35.1%). Clinical drug resistance were found in nine patients and HIV gene mutations were detected in these patients.
Conclusions: Chinese treatment-naive AIDS patients have achieved good virological and immunological response to generic-drug-predominant HAART regimes with low drug resistance, but relatively more side effects.
