Abstract
HIV-1 is divided into different subtypes and circulating recombinant forms (CRFs) but the impact of HIV-1 subtype/CRF on disease progression is not fully understood. We determined the HIV-1 subtype/CRF of 152 seroincident individuals from Guinea-Bissau, based on the C2-V3 region of env. Rate of disease progression was measured as time from estimated seroconversion to AIDS and AIDS-related death. Hazard ratios (HRs) were calculated using a Cox proportional hazard model, adjusting for gender and age at seroconversion. The major subtypes/CRFs identified were CRF02_AG (53%), A3 (29%) and A3/02 (a recombinant of A3 and CRF02_AG) (13%). Infection with A3/02 was associated with a close to 3-fold increased risk of AIDS and AIDS-related death... (More)

The major subtypes/CRFs identified were CRF02_AG (53%), A3 (29%) and A3/02 (a recombinant of A3 and CRF02_AG) (13%). Infection with A3/02 was associated with a close to 3-fold increased risk of AIDS and AIDS-related death compared to A3 (HR=2.6 [P=0.011] and 2.9 [P=0.032], respectively). The median estimated time from seroconversion to AIDS and AIDS-related death was 5.0 and 8.0 years for A3/02, 6.2 and 9.0 years for CRF02_AG and 7.2 and 11.3 years for A3. Our results show that there are significant differences in disease progression between HIV-1 A-like subtypes/CRFs. Individuals infected with the A3/02 recombinant have among the fastest progression rates to AIDS reported to date. Determining the HIV-1 subtype of infected individuals could be of importance in the management of HIV-1 infections. (Less)
