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: To determine incidence and risk factors of nevirapine (NVP)-associated severe hepatitis that led to NVP discontinuation among HIV-infected patients with CD4 < 250 cells/microL. MATERIAL AND METHOD: A retrospective cohort study was conducted among antiretroviral-naïve HIV-infected patients who had baseline CD4 < 250 cells/microL and were initiated NVP-based antiretroviral therapy (ART) between January 2003 and October 2005. All patients were categorized to group A: occurred clinical hepatitis and group B: did not occur clinical hepatitis. All were followed until 6 months after ART. RESULTS: There were 910 patients with a mean age of 35.4 years, 57% were males and median (IQR) CD4 cell count was 27 (9-80) cells/microL; contributing 5,006 person-months of observations. Ten (1.1%) patients were in group A and 900 (98.9%) patients were in group B. Incidence of clinical hepatitis was 2 per 1,000 person-months. Probabilities of clinical hepatitis at 0.5, 1, 2, 3 and 6 months after ART were 0.2%, 0.5%, 0.7%, 0.8% and 1.1%, respectively. By Cox regression analysis, baseline AST > or = 1.5 times of upper limit was associated with higher incidence of clinical hepatitis (p = 0.019, HR = 5.83, 95% CI = 1.33-25.51). CONCLUSION: Incidence of NVP-associated severe hepatitis that lead to NVP discontinuation among HIV-infected patients with baseline CD4 < 250 cells/microL is low. The higher baseline AST is also associated with a higher risk of severe hepatitis.
