BACKGROUND Due to the establishment of the National Access to Antiretroviral Program for People who have AIDS (NAPHA), approximately 80,000 Thai HIV-1 infected patients received antiretroviral drugs through the NAPHA program, which was completed at the end of 2005. The development of drug resistance is required for access to ARV drugs. The objective of this(More)
The aims of this study were to illustrate the prevalence and determinants of mutations associated with antiretroviral drug resistance in a group of antiretroviral-naive and treatment-experienced patients in Thailand, where antiretroviral drugs are widely used. One hundred and thirteen treatment-naive (92 CRF01_AE and 21 subtype B patients) and 1,709(More)
Genotypic testing using TRUGENE was performed for treatment-naive, human immunodeficiency virus type 1 (HIV-1)-infected patients at baseline and after initiation of protease inhibitor (PI)-based highly active antiretroviral therapy (HAART) regimens. The genetic diversity of HIV-1 pol sequences from 92 CRF01_AE and 21 B strains was compared. Subsequently,(More)
The aim of this study was to develop a rapid, sensitive and robust procedure for the qualitative detection of SARS coronavirus RNA. Three unique detection formats were developed for real-time RNA amplification assays: a post amplification detection step with a virus-specific internal capture probe based on Taqman (RT-PCR TaqMan assay), hybridization probe(More)
To determine the prevalence of antiretroviral resistance in treatment-failure HIV-1 infected individuals, under the initiative of the non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen in Thailand, plasma samples were collected from 1,376 HIV-1 infected patients, who were failing in their current HAART therapy during 2000-2004. They were(More)
