Implication

Prospective cohort study observes high virological suppression across diverse viral strains in treatment-naive individuals, indicating that viral subtype does not hinder antiretroviral therapy.

Key Points

To evaluate whether different HIV-1 genetic subtypes affect short-term virological suppression in patients initiating combination antiretroviral therapy.
Prospective study of N=172 antiretroviral drug-naive patients in Sweden starting therapy between January 1998 and January 2002 with 6 months of follow-up.
Identified HIV-1 subtypes (32 A, 44 B, 34 C, 18 D, 5 G, and 19 CRF01_AE) through direct sequencing of env or pol gene regions.
Evaluated treatment response using plasma HIV-1 RNA levels, CD4 cell counts, and prescribed antiretroviral regimens.
Achieved undetectable plasma HIV-1 RNA levels in 84% of all patients after 6 months of antiretroviral therapy.
Identified that ethnicity, rather than viral genetic subtype, correlated with virological response in univariate analysis, with undetectable viral load rates of 77% in patients of African origin, 91% in Caucasians, and 100% in Asians.
