ABSTRACT
Acute Hepatitis E virus (HEV) infection in people living with HIV/AIDS (PLHA) can lead to fulminant hepatic failure, cirrhosis and death. The prevalence of anti-HEV antibodies within this group varies according to the geographical area. However, in South America, studies concerning the detection of HEV in PLHA are rare. Here, we investigated the presence of HEV by serological and molecular detection and evaluated the risk factors associated with infection in PLHA in Pernambuco state, Brazilian Northeast. Serological and molecular detection of HEV was performed in 366 samples of PLHA by ELISA for anti-HEV IgG and RT-PCR, respectively. Anti-HEV IgG prevalence was 4.1% (15/366) and no HEV RNA was detected. Concerning the risk factors, we evaluated, in multivariable analysis, age, years of school, sexual orientation, oral-anal sex, use of injectable drugs and piped water. Among them, only piped water availability could be associated with the HEV infection in PLHA (OR: 0.08; CI 95%: 0.01-0.66; p = 0.0182). This study showed for the first time the association of piped water as protection factor for HEV infection in PLHA. Finally, this is also the first report of HEV seroprevalence in PLHA in the Northeast Brazil.

This cross-sectional study aimed to estimate the seroprevalence and risk factors for Human herpesvirus 8 (HHV-8) infection among people living with HIV/AIDS in Recife, Pernambuco, Brazil. A total of 500 individuals were tested for antibodies against HHV-8 using the whole-virus ELISA. The prevalence of anti-HHV-8 was 28.6% and the frequency among 140 men who have sex with men (MSM) was 38.6%. In the univariate model, there were significant associations with male gender, detectable HIV load, travel abroad, bissexual, and homossexual orientation. The first HHV-8 seroepidemiologic study, in northeast Brazil, documents a highly prevalent HHV-8 infection among MSM living with HIV/AIDS. J. Med.
