ABSTRACT
The present study evaluated the incidence and risk factors that correlated with the development of non-nucleoside reverse transcriptase inhibitor (NNRTI) related rash in 69 Thai children followed prospectively. The overall incidence of NNRTI-related rash was 16% (22% for NVP and 4% for EFV rash). The only significant predictive factor that correlated with the development of NNRTI-related rash in a multivariate logistic regression model was a CD4% decrease at week 12.

BACKGROUND: Multi-drug resistant HIV mutants have been reported after prolonged dual antiretroviral therapy. OBJECTIVE: To evaluate the prevalence and resistance pattern in HIV-infected children treated with dual NRTIs. MATERIAL AND METHOD: Records of HIV-infected children treated with dual NRTIs at Srinagarind Hospital, Khon Kaen University, Thailand, were reviewed for baseline data and their consensually-stored plasma were checked for the occurrence of HIV mutants by genotyping. RESULTS: Fifty-seven HIV-infected children were treated with dual NRTI regimens (27 males; 30 females). The median age and median CD4+ T-lymphocyte at genotypic testing were 83.5 months and 10.9%, respectively. The median duration of ARV therapy was 22 months. More than half the children (42) were on zidovudine and didanosine. A set of three or more nucleoside analog mutations (NAMs), conferring multi-dideoxynucleoside resistance, was found in 60% of the cases. CONCLUSION: High percentages of NAMs were found in HIV-infected children previously on dual ARV therapy for long periods. Genotypic testing was helpful in designing the second antiretroviral regimen.

OBJECTIVE: To evaluate the efficacy and safety of CHQ in a combination treatment with ZDV/ddI in HIV-1-infected children. MATERIAL AND METHOD: Fifty five HIV-infected children were randomly enrolled into 3 treatment groups: (I) ZDV + ddI (n = 25); and (II) ZDV + ddI + CHQ (n = 21); and (III) ZDV + ddI experienced children were non-randomly added CHQ (n = 9). Weight, CD4+ T-lymphocytes and plasma HIV-RNA were measured at weeks 0, 8 and 24. RESULTS: Fifteen, 16 and 8 children from Groups I, II and III were evaluated. No significant improvement in the mean Z-score for weight in groups I and II, but a decrease occurred in group III after 6 months of therapy. In group I, II and III, the respective change in the mean CD4+ T-lymphocyte percentage was +6.7, +4.0 and -0.6. The decrease in the plasma HIV-RNA log was 0.9, 1.1 and 0.7, respectively. There was a trend for more nausea/vomiting in group II/III and more opportunistic infections in group III. CONCLUSION: 1. The addition of chloroquine in ZDV/ddI regimen provided no significant improvement in clinical, immunological and virological parameters. 2. Chloroquine induced immunosuppression and nausea complicated its use.
