Low bone mass prevalence, therapy type, and clinical risk factors in an HIV-infected Brazilian population.

Low bone mineral density (BMD) has been described in human immunodeficiency virus (HIV)-infected patients, but data on associated factors are still unclear, and to our knowledge, no reports are available in Brazil. Our goal was to evaluate BMD in HIV patients attending an outpatient clinic in Vitoria, Brazil. A sectional study was performed in 300 HIV-infected patients to measure BMD by dual-energy X-ray absorptiometry (DXA).

[Risk factors related to renal disorders in HIV-1 infected patients].

Introduction: Renal disease has emerged as one of the primary comorbid conditions affecting HIV-infected patients, mainly because antiretroviral therapy has improved survival. This study aimed to detect risk factors possibly associated with altered renal function in HIV-infected patients.

Methods: A cross-sectional study was conducted involving 254 HIV-infected patients attending an outpatient clinic at Santa Casa de Vitoria< They were interviewed and blood samples were collected for CD4 cell counts, HIV-1 viral load, glucose, lipids and creatinine measurements.

Longitudinal comparison between plasma and seminal HIV-1 viral loads during antiretroviral treatment.

This study was designed to investigate the impact of anti-retroviral therapy on both plasma and seminal HIV-1 viral loads and the correlation between viral loads in these compartments after treatment. Viral load, CD4+ and CD8+ T-cell counts were evaluated in paired plasma and semen samples from 36 antiretroviral therapy-naive patients at baseline and on days 45, 90, and 180 of treatment. Slopes for blood and seminal viral loads in all treated patients were similar (p = 0.

Lack of correlation between seminal and plasma HIV-1 viral loads is associated with CD4 T cell depletion in therapy-naïve HIV-1+ patients.

The present study was conducted to investigate a possible correlation between plasma (PVL) and seminal viral load (SVL) on treatment-naïve HIV-1-infected patients in Vitória, ES, Brazil. We also evaluated whether the progressive immunosuppression associated with HIV disease (as evidenced by declining CD4 T cell counts) has any impact on the correlation between PVL and SVL HIV-1. Viral load on paired blood and semen samples from 56 consecutive treatment-naïve patients were evaluated and compared to CD4 cell counts.
