“The aim of the study was to determine the risk factors predictive of symptomatic HIV-associated neurocognitive disorders (sHAND)

among HIV-infected patients receiving active medical care. Baseline demographic PLX-4720 price and clinical characteristics were analysed in patients with sHAND (HIV-associated dementia and minor neurocognitive disorder) in a population-based longitudinal cohort of HIV-infected patients with access to universal health care, including combination antiretroviral therapy (cART) from 1999 to 2008. Variables evaluated for their association with sHAND included age and ethnicity, survival duration with HIV-1 infection, vascular disease risk factors, and laboratory indices such as blood CD4 T-cell count at its nadir

and at cART initiation, using both univariable and multivariable logistic regression models. A total of 1320 patients were investigated, including the patients diagnosed with sHAND (n = 90) during the study period. In univariable analyses, increased age, increased length of survival with HIV, low nadir CD4 and CD8 T-cell counts, high baseline viral load (> 1 000 000 HIV-1 RNA copies/mL), and African origin were predictive of a diagnosis of sHAND (P < 0.05). In multivariable analysis, increased age, increased length of survival, low nadir CD4 T-cell counts, and high baseline viral load remained predictive of sHAND (P < 0.05). Remarkably, CD4 T-cell www.selleckchem.com/products/Fulvestrant.html counts at cART initiation, hepatitis C virus coinfection, and vascular disease risk factors failed to predict

sHAND in both analyses. Increased age and survival duration, lower nadir CD4 T-cell counts, and higher baseline viral load were consistent predictors of the development of sHAND among persons with HIV/AIDS in universal health care, underscoring the importance of attention to these variables in clinical care. “
“The aim of the study was to determine total and unbound lopinavir (LPV) plasma concentrations in HIV-infected pregnant women receiving lopinavir/ritonavir (LPV/r tablet) undergoing therapeutic drug monitoring (TDM) during pregnancy and postpartum. GBA3 Women were enrolled in the study who were receiving the LPV/r tablet as part of their routine prenatal care. Demographic and clinical data were collected and LPV plasma (total) and ultrafiltrate (unbound) concentrations were determined in the first, second and third trimesters using high-performance liquid chromatography–tandem mass spectrometry (HPLC-MS/MS). Postpartum sampling was performed where applicable. Antepartum and postpartum trough concentrations (Ctrough) were compared independently [using analysis of variance (anova)] and on a longitudinal basis (using a paired t-test). Forty-six women were enrolled in the study (38 Black African). Forty women initiated LPV/r treatment in pregnancy.
