Genetic characterization of HIV-1 from semen and blood from clade C-infected subjects from India and effect of therapy in these body compartments.
Biologic and genetic differences between HIV-1 clade C in India and clade B in US suggest that the effect of anti-viral therapy in various body compartments may differ between these two clades. We examined the effect of therapy on viral loads in semen and blood of HIV-1-clade C infected subjects from India and evaluated whether HIV-1 in the semen is different from that in blood in these subjects. HIV-1 RNA was detected in semen and blood at all stages of the disease. Viral loads in semen and blood were strongly correlated with each other, but not with the CD4+ T cell count. Anti-viral treatment reduced viral load drastically in blood and semen within one month of post therapy. Genetic characterization of HIV-1 in the semen and blood demonstrated that they were highly compartmentalized. These data have important implications of sexual transmission of HIV-1 in clade C HIV-1 infected subjects.
