Transmitted Drug Resistance and Antiretroviral Treatment Outcomes in Non-subtype B HIV-1-infected Patients in South East Asia

Abstract

Background: We compared treatment outcomes of transmitted drug resistance (TDR) in patients on fully or partially sensitive drug regimens.

Methods: Factors associated with survival and failure were analyzed using Cox proportional hazards and discrete time conditional logistic models.

Results: TDR, found in 60 (4.1%) of 1471 Asian treatment-naive patients, was one of the significant predictors of failure. Patients with TDR to >1 drug in their regimen were >3 times as likely to fail compared to no TDR.

Conclusions: TDR was associated with failure in the context of non-fully sensitive regimens. Efforts are needed to incorporate resistance testing into national treatment programs.
