Genomic Detection of the Emerging, Highly Pathogenic HIV-1 Subtype D in Bahia, Northeast Brazil.

(1) Background: The HIV subtype D is generally associated with a faster decline in CD4 T cell counts, a higher viral load, and a faster progression to AIDS. However, it is still poorly characterized in Brazil. In this study, we used genomics and epidemiological data to investigate the transmission dynamics of HIV subtype D in the state of Bahia, Northeast Brazil.

High seroprevalence of Leishmania infantum is linked to immune activation in people with HIV: a two-stage cross-sectional study in Bahia, Brazil.

Visceral leishmaniasis is an opportunistic disease in HIV-1 infected individuals, unrecognized as a determining factor for AIDS diagnosis. The growing geographical overlap of HIV-1 and infections is an emerging challenge worldwide, as co-infection increases morbidity and mortality for both infections. Here, we determined the prevalence of people living with HIV (PWH) with a previous or ongoing infection by and investigated the virological and immunological factors associated with co-infection.

Factors associated with non-adherence to antiretroviral therapy in adults with AIDS in the first six months of treatment in Salvador, Bahia State, Brazil.

The control of viral replication is essential in the highly active antiretroviral therapy (HAART), and adherence to therapy is instrumental for such control. Individual and external factors influence adhesion to the use of antiretroviral (ARV) drugs. This is a cross-sectional study to investigate factors associated with non-adherence to HAART in AIDS patients in Salvador, Bahia State, Brazil, with age ≥ 13 years and first prescription in 2009.
