HIV infection is associated with left ventricular (LV) dysfunction and accelerated atherosclerosis. These conditions result in elevation of plasma natriuretic peptide (NP) levels. The present study compares N-terminal-pro-BNP (NT-pro-BNP) levels in HIV-infected and -uninfected women and identifies factors influencing NT-pro-BNP levels in HIV-infected women. A total of 454 HIV-infected and 200 HIV-uninfected participants from the Women's Interagency HIV Study (WIHS) had NT-pro-BNP determination. Elevated NT-pro-BNP level was defined using previously determined age stratified cut-off values of >164 ng/liter (age <60 years) and >225 (age > or = 60 years). HIV-infected women were older (41.6 +/- 8.9 vs. 38.9 +/- 10.5 years, p < 0.01) and were more likely to have anemia, hepatitis C virus (HCV) antibodies, and kidney dysfunction than HIV-uninfected women. HIV-infected women had significantly higher NT-pro-BNP levels (142.4 +/- 524.8 vs. 73.6 +/- 115.1 ng/liter, p = 0.01) and a higher prevalence of elevated NT-pro-BNP (12.1% vs. 7.5%; p = 0.08). In univariate analyses, elevated NT-pro-BNP was significantly associated with age, systolic BP, hypertension, anemia, triglyceride levels, kidney disease, and HCV seropositivity, but not HIV infection. In multivariate analysis, elevated NT-pro-BNP levels were significantly associated with anemia and kidney function, and had a borderline association with the presence of HCV antibodies. Among HIV-infected women, NT-pro-BNP levels were not independently associated with measures of severity of infection or with HAART use. Although HIV-infected women have higher NT-pro-BNP levels than HIV-uninfected women, the differences are due to non-HIV factors such as anemia, kidney disease, and HCV coinfection. These findings suggest that natriuretic peptide levels are a global marker of comorbidity in the setting of HIV infection.

Highly active antiretroviral therapy has greatly reduced AIDS-related morbidity and mortality; however, its widespread use has been associated with a marked rise in the frequency of cardiovascular diseases in patients with HIV. Moreover, HIV infection is associated with accelerated coronary atherosclerosis and vasculopathy, although the mechanisms underlying these findings have not been determined. We describe the case of a 45-year-old woman with HIV/HCV coinfection, irritable bowel syndrome, and accelerated progression of coronary atherosclerosis after execution of percutaneous coronary intervention (PCI). In this case, the rapidity of progression of atherosclerosis seems linked principally to chronic inflammation and excess immune activation that can depend by a concourse of factors (chronic C hepatitis, irritable bowel syndrome, PCI execution) not directly associated with traditional risk factors. Caregivers following HIV-infected patients should be aware of the increased risk of accelerated atherogenesis in these subjects, principally in case of presence of causes of intense immune activation.
