BACKGROUND: Metabolic syndrome (MS) is usually diagnosed based on presence of abdominal obesity, elevated blood pressure, elevated fasting plasma glucose, high serum triglycerides (TG) and low high-density lipoprotein levels (HDL). Whether HIV is associated with a higher prevalence of metabolic syndrome than general population remains unclear. AIM: Aim of the study was to determine the incidence of metabolic syndrome in the population of HIV infected adults and its association with clinical, virological and biochemical features...

OBJECTIVES: Poor immunological recovery in treated HIV-infected patients is associated with greater morbidity and mortality. To date, predictive biomarkers of this incomplete immune reconstitution have not been established. We aimed to identify a baseline metabolomic signature associated with a poor immunological recovery after ART in order to envisage the underlying mechanistic pathways that influence the treatment response. DESIGN: This was a multi-centre, prospective cohort study in ART-naïve and a pre-ART low nadir (<200 cells/μl) HIV-infected patients (n = 64)...

Human immunodeficiency virus (HIV) infection is a growing concern for health workers. The two major components of dyslipidemia in HIV infected patients are hypertriglyceridemia and decreased levels of high density lipoprotein (HDL) which contribute to increased atherosclerotic risk. The study included 150 newly diagnosed HIV patients and 150 healthy controls. In all these cases Lecithin cholesterol acyl transferase (LCAT) activity was assessed by measuring the difference between esterified and free cholesterol by digitonin precipitation method and levels of Apolipoprotein A-I (apo A-I) were measured by immunoturbidimetric method...

Longitudinal measurement of biomarkers is important in determining risk factors for binary endpoints such as infection or disease. However, biomarkers are subject to measurement error, and some are also subject to left-censoring due to a lower limit of detection. Statistical methods to address these issues are few. We herein propose a generalized linear mixed model and estimate the model parameters using the Monte Carlo Newton-Raphson (MCNR) method. Inferences regarding the parameters are made by applying Louis's method and the delta method...

BACKGROUND: HIV-infected individuals, even well controlled with combined antiretroviral therapy (cART), have systemic inflammation and comorbidities. Substance P (SP) is an undecapeptide, which mediates neurotransmission and inflammation through its cognate neurokinin 1 receptor (NK1R). Plasma SP levels are elevated in HIV-infected individuals. The FDA-approved antiemetic aprepitant, an NK1R antagonist, has anti-HIV effects and antiinflammatory actions. We evaluated the safety, pharmacokinetics, and antiinflammatory properties of aprepitant in HIV-positive individuals receiving cART...

BACKGROUND & OBJECTIVES: Cardiovascular disease (CVD) risk with low high-density lipoprotein cholesterol (HDL-C) and high triglycerides is common in the general population in India. As nevirapine (NVP)-based antiretroviral therapy (ART) tends to increase HDL-C, gene polymorphisms associated with HDL-C metabolism in HIV-infected adults on stable NVP-based ART were studied. METHODS: A cross-sectional study was conducted between January 2013 and July 2014 among adults receiving NVP-based ART for 12-15 months...

Context: In the general population, high-density lipoprotein (HDL) cholesterol efflux capacity (HCEC) relates inversely to incident cardiovascular events. Previous studies have suggested that HCEC is decreased in HIV and that antiretroviral therapy (ART) initiation might improve HCEC. Objective: To evaluate HCEC in the context of ART initiation and immune activation in HIV. Design and Outcome Measures: Baseline HCEC from 10 ART-naive HIV-infected males and 12 prospectively matched non-HIV-infected males were analyzed...
