To anticipate the potential use of anti-integrase drugs in Indonesia for treatment of HIV-1 infection, the development of a drug resistance genotyping assay for anti-integrase is crucial in identifying the genetic drug resistance profile of Indonesian HIV-1 strains. This experiment aimed to amplify a target region in the integrase gene of Indonesian HIV-1 subtypes CRF01-AE and B that contain genetic mutations known to confer resistance to anti-integrase drug. Eleven archived plasma samples from individuals living with HIV-1 were obtained from the Virology and Cancer Pathobiology Research Center for Health Service (VCPRC FKUI-RSCM) laboratory. One of the plasma samples contained HIV-1 subtype B, and the remaining plasma samples contained subtype CRF01-AE. The target regions for all samples were amplified through RT-PCR, with an annealing temperature of 55 °C, using the primer pair AE-POL 4086F and AE-POL 5232R that were designed by VCPRC FKUI-RSCM. The results of this experiment show that 18.2% (2/11) of the samples were successfully amplified using the one-step RT-PCR. While the primer pair was effective in amplifying the target region in the integrase gene sequence for subtype B (100%; 1/1), it had a low efficacy (10%, 1/10) for subtype CRF01-AE. In conclusion, the primer pair can be used to amplify the target region in Indonesian HIV-1 strain subtypes CRF01-AE and B. However, optimization of the PCR condition and an increased number of samples would help to determine an accurate representation of the efficacy of the primer pair.
