Abstract: BACKGROUND: More than 100,000 patients have been treated, since the implementation of the National Universal Coverage for antiretroviral therapy (ART) in Thailand Although there are several comprehensive guidelines available internationally, there is a need to have guidelines that can be implemented in Thailand. MATERIAL AND METHOD: The guidelines were developed by a panel of 17 members who are the experts on HIV research and/or HIV patient care and appointed without incentive by the Thai AIDS Society (TAS). The recommendations were based on evidences from the published studies and availability of antiretroviral agents. Published studies that are relevant and applicable to Thailand in particular have been taken into consideration. RESULTS: The recommendations include: when to start ART; what to start; how to monitor the therapy; adverse effects and its management; diagnosis of treatment failure; and antiretroviral treatment options in patients with treatment failure. ART in special circumstances, i.e., patients with co-infection of tuberculosis or hepatitis B virus, is also included Appropriate level of CD4+ T-cell count to start ART among Thai patients has been considered carefully. The authors recommend to start ART at CD4+ T-cell count < 200 cells/mm3. CONCLUSION: ART should be initiated in adults and adolescents HIV-1 infected patients with a history of HIV-related illness or AIDS or with a CD4+ T-cell count <200 cells/mm3. For treatment-naive patients, the preferred initial therapy is a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen. CD4' T-cell count and viral load should be monitored for at least twice and once a year, respectively. Proper management of antiretroviral-related toxicity and enhancement of adherence are crucial for the long-term success of ART.

Abstract: OBJECTIVES: Long-term nonnucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral treatment failure in most developing countries has led to broad cross-resistance within NNRTI and nucleoside reverse transcriptase inhibitor (NRTI) classes. In this study, we investigated the efficacy and tolerability of a double boosted protease inhibitor (PI) regimen in this setting. METHODS: A total of 64 HIV-infected patients who had failed NNRTI-based regimens were randomized to receive either lopinavir/saquinavir/ritonavir [LPV/SQV/r; 400/1000/100 mg twice a day (bid)] alone or indinavir/ritonavir (IDV/r; 800/100 mg bid) plus two NRTIs optimized with genotypic drug resistance guidance. Patients who had no available optimized NRTI backbone were allocated to the LPV/SQV/r arm. RESULTS: At 48 weeks, the percentages of patients with plasma viral load<50 HIV-1 RNA copies/mL were 60% (31 of 52 patients) in the LPV/SQV/r arm vs 50% (six of 12) in the IDV/r/2NRTIs arm in the intent-to-treat (ITT) analysis, and 61% (31 of 51) vs 71% (five of seven), respectively, in the as-treated analysis. The median (interquartile range) increases in absolute CD4 cell count from baseline were 177 (91-269) and 100 (52-225) cells/microL in the LPV/SQV/r and IDV/r/2NRTIs groups, respectively (P=0.32). Four of 12 patients (33%) in the IDV/r/2NRTIs group experienced severe nausea and vomiting and four patients (8%) in the LPV/SQV/r group had significant hepatitis. CONCLUSIONS: LPV/SQV/r and high-dose boosted IDV were not well tolerated and led to <65% ITT virological efficacy outcomes. A randomized larger scale study with new formulations and/or more tolerable boosted PIs in NNRTI-based failure is warranted.
