Virologic correlates of anti-CMV IgG levels in HIV-1-infected men.

ABSTRACT: In human immunodeficiency virus (HIV)-infected individuals, higher levels of anti-cytomegalovirus (CMV) immunoglobulin G (IgG) antibody have been associated with increased immune activation, increased HIV transmission, cardiovascular complications, and neurocognitive impairment. However, the mechanism of these observations is unknown. This analysis of 228 HIV-infected men found that higher CMV IgG levels were positively associated with older age and antiretroviral treatment. Higher frequency of detectable CMV in peripheral blood mononuclear cells and recurrent seminal CMV reactivations were associated with lower plasma CMV IgG levels, suggesting that immune response to CMV rather than direct effect of viral replication is likely responsible for adverse clinical outcome observed in other studies.

Project description:IntroductionIn the HIV-infected individuals, physical activity improves physical strength, quality of life and reduces the risk of developing non-communicable diseases. In Sub-Saharan Africa, HIV-infected patients report being less active compared to HIV-uninfected individuals. We assessed the levels and correlates of objectively measured physical activity and capacity among HIV-infected antiretroviral therapy (ART)-naive individuals compared to HIV-uninfected individuals in Mwanza, Tanzania.MethodWe conducted a cross-sectional study among newly diagnosed HIV-infected ART-naive individuals and HIV-uninfected individuals frequency-matched for age and sex. Socio-demographic data, anthropometrics, CD4 counts, haemoglobin level, and C-reactive protein (CRP) were collected. Physical activity energy expenditure (PAEE) was assessed as measure of physical activity whereas sleeping heart rate (SHR) and grip strength were assessed as measures of physical capacity. Multivariable linear regression was used to assess the correlates associated with physical activity and capacity.ResultsA total of 272 HIV-infected and 119 HIV-uninfected individuals, mean age 39 years and 60% women participated in the study. Compared to HIV-uninfected individuals, HIV-infected had poorer physical activity and capacity: lower PAEE (-7.3 kj/kg/day, 95% CI: -11.2, -3.3), elevated SHR (7.7 beats/min, 95%CI: 10.1, 5.3) and reduced grip strength (-4.7 kg, 95%CI: -6.8, -2.8). In HIV-infected individuals, low body mass index, moderate-severe anaemia, low CD4 counts and high CRP were associated with lower physical activity and capacity. In HIV-uninfected individuals, abdominal obesity and moderate anaemia were associated with lower physical activity and capacity.ConclusionHIV-infected participants had lower levels of physical activity and capacity than HIV-uninfected participants. Correlates of physical activity and capacity differed by HIV status. Management of HIV and related conditions needs to be provided effectively in health care facilities. Interventions promoting physical activity in these populations will be of importance to improve their health and reduce the risk of non-communicable diseases.
