PROTOCOL SUMMARY This is a prospective, randomized open-label, 2 arm, 3-phase trial to compare the 48-weeks virological response of two different regimens containing abacavir/lamivudine (abacavir/lamivudine +darunavir/ritonavir (DRV/r) vs abacavir/lamivudine + raltegravir (RAL) in antiretroviral therapy naive, HIV+ individuals presenting for care with CD4+ counts < 200/mm3. 1.1 Clinical Objectives: Primary Objective: To compare the 48-week virological response to two different regimens containing abacavir/lamivudine (abacavir/lamivudine +darunavir/ritonavir (DRV/r) vs abacavir/lamivudine + raltegravir (RAL) in antiretroviral therapy naive, HIV+ individuals presenting for care with CD4+ counts < 200/mm3. Secondary Objective: a) To compare immunological response at 48 weeks; b) To determine the safety and tolerability of the 2 regimens. 1.2 Study population: 350 in/out patients 1.3 Outcome Primary Endpoint - Proportion of patients with HIV RNA<50 copies/mL after 48 weeks Secondary Endpoints(s) - Change in CD4+ cell count from baseline through week 48 - Time to virological rebound 1.4 Study design: Multicentre, parallel group, randomised, open label, non-inferiority study 1.5 Treatment regimens: Arm A: abacavir/lamivudine 1 tablet once a day + raltegravir 400 mg (1 tablet twice a day) Arm B: abacavir/lamivudine 1 tablet once a day + ritonavir 100 mg + darunavir 800 mg once a day. All drugs have been approved for the treatment of HIV infection. The study population will consist of 350 HIV-positive, HLA B5701-negative patients. At baseline, patients will be randomized 1:1 to start abacavir/lamivudine plus either raltegravir or darunavir/ritonavir. Randomization will be stratified on the basis of the screening CD4+ cell count (≤100 vs ≥100 cells/µL), to ensure balance across treatments groups 1.7 Criteria for Safety: Adverse events and laboratory assessments. 1.8 Statistical analysis: As this is a non-inferiority trial, we will calculate the difference in the proportions of patients experiencing the primary outcome in the two treatment arms and will calculate a 95% confidence interval for this. Non-inferiority of the raltegravir arm will be demonstrated if the lower limit of the 95% confidence interval is greater than -12%. In case non-inferiority will be met, analyses for superiority will be performed.
Primary Objective: To compare the impact of switching from efavirenz (EFV) plus two nucleoside analogs to rategravir (RAL) plus two nucleoside analogs versus keeping the same antiretroviral regimen on hepatic steatosis (HS) as measured by the controlled attenuation parameter (CAP) among HIV/HCV-coinfected patient. Secondary Trial Objective: 1. To compare the proportion of HIV/HCV-coinfected patients with one category decrease in the grade of HS between patients continuing with EFV plus two nucleoside analogs and those switching from EFV plus two nucleoside analogs to RAL plus two nucleoside analogs. 2. To evaluate the proportion of patients who maintain viral control (HIV RNA < 50 copies/mL) after switching. Design: Open-label, randomized clinical trial to evaluate safety (phase IV) Condition: HIV and HCV coinfection. Intervention: Patients on current EFV plus two nucleoside analogs will be randomly assigned to switch EFV to RAL (400mg BID), maintaining nucleoside analogs unchanged, or to continue the current regimen.

Methodology multicentric, comparative study Estimated enrollment 31 participants in total 1. st group of- 15 people living with HIV undergoing CABG (coronary heart disease HIV+ group) 2. nd group of- 16 people without HIV- undergoing CABG (coronary heart disease HIV- group) People without HIV-will be matched to people living with HIV+ by : age (± 5 years) and sex Outcomes Primary outcome: Comparative analysis of the inflammatory profile of the EAT : expression profile of the pro and anti inflammatory cytokines and adipokines within the EAT in both groups of participants : coronary heart disease HIV+ and HIV- groups Secondary outcomes : - Determination of the EAT volume by echocardiography and cardiac scanner for both groups - Macroscopic profile of the EAT : adipocytes, fibrosis, endothelial cell density) - RT-PCR analyses : renin, adiponectine, PPARɣ - Comparatison of the inflammatory and macroscopic profiles between the EAT and the subcutaneous adipose tissue in the two groups by ARN messagers analysis.

A prospective cross-sectional study evaluates nutritional status and its relationship to the related factors in Thai HIV-infected patients who attending in out patient clinic.
This project aims at characterizing HIV-1 viral biofilms structural and functional properties and at deciphering its role as a new viral reservoir and as a new mode of viral spread. The prospective national study will be conducted on cells isolated from blood samples from 20 patients infected with HIV.
A proof of concept study to evaluate the feasibility of using the Shang Ring, a novel male circumcision device across all childhood age groups namely infants (under 1), 1-5 age group, 6-12 age group and the 13-17 age group. The study will evaluate the safety, efficacy and course of wound healing when using the Shang Ring technique across the four childhood age groups.
The primary purpose of this study is to investigate the steady-state pharmacokinetics of efavirenz in older HIV-infected patients as compared to historical controls; to investigate the relationship of drug exposure to neuropsychiatric side effects and neuropsychological performance; and to explore the role of host polymorphisms in drug metabolism in the older patient.
To address the question of the comparison of two courses of Vivitrol with differing lengths in 130 HIV negative, consenting, opioid addicted patients who have completed inpatient treatment. Participants will be randomized under double blind conditions to a 24 or 48-week course of pharmacotherapy, along with bi-weekly drug counselling, over 48 weeks, with follow-ups at weeks 60 and 72. The 24-week cohort will receive Vivitrol placebo injections in weeks 24 to 48.
Potent HIV suppression with Darunavir-based antiretroviral therapy (ART) will lead to repopulation of gastrointestinal-associated lymphoid tissue (GALT) cluster of differentiation (CD)4+ T-cell populations, normalization of systemic immune activation, and improved HIV-associated cardiovascular disease (CVD) risk.
The objective of the present study is to analyze the overall tubular function, and in particular that from the proximal tubule and the thick ascending loop of Henle (TALH) in patients with HIV infection receiving or not tenofovir-containing antiretroviral treatment in comparison with seronegative controls, by applying a validated tubular physiological test known as "Low sodium infusion test". Hypothesis is that patients with HIV infection and normal renal function will show subclinical tubular abnormalities compared with seronegative controls
