Filter by:The aims of this study are to obtain pharmacokinetic data on interactions between dolutegravir (DTG) and immunosuppressant drugs (Cyclosporine A, Tacrolimus, Sirolimus and Mycophenolic acid) in solid organ transplant (SOT) recipients to provide proof of principle data that DTG plus 2 nucleosides (NUCs) is safe and effective in HIV-infected SOT recipients.
The study was done to: - Start antiretroviral therapy (ART) early in those recently or acutely infected with HIV-1 - See how starting ART as soon as the infection is found affects the amount of HIV-1 in blood and how well the body fights the HIV-1 infection - Look at the amount of HIV-1 DNA (genetic material for HIV-1) seen in CD4+ T-cells (infection-fighting cells in blood) after 48 weeks of ART - See how early treatment for HIV affects the numbers of HIV-1 infection fighting cells (CD4+ and CD8+ T-cells) in blood
Long term safety follow-up of Cal-1 recipients
Objectives: MAIN: To evaluate the parameters of microbial translocation after treatment with probiotics (Saccharomyces boulardii) in HIV+ patients and its role on immune reconstitution and the changes in gut microbiota composition. SECONDARY OBJECTIVES: 1) To analyze the progress of immune activity markers after the administration of probiotics. 2) To determine the improvement of CD4+ lymphocytes and HIV viral load in patients after taking probiotics. Methods: Design: A prospective randomized open controlled double-blinded trial, to be performed at a tertiary care hospital in Barcelona. Subjects: Chronic HIV infected patients. Sample size: 44 cases. They´ll be divided in 2 groups: (1) Patients with CD4 +> 400 cells / ml and undetectable viral load for more than two years (22 cases) and (2) Patients with immunodiscordancy, defined as patients with CD4 + T cells lower than 350 cells / ml despite 4-7 years of effective antiretroviral therapy. (22 cases). Intervention: Patients were randomized in 2 subgroups: (A) they´ll receive daily oral supplementation with S. boulardii for 3 months and (B) they ´ll receive placebo. Variables: bacterial lipopolisaccharide levels measured by the Lipid-Binding protein (LBP), parameters of immune activation in plasma (soluble CD14, IFN-Υ, TNF-Alpha, IL (interleukine)-2, IL-5, IL-6, IL-12)and gut microbiota composition prior to the use of probiotics (baseline), at 3 and 6 months. Immunological and clinical data. Outcome measures: quantification of bacterial translocation levels, markers of activity and immune recovery. Analysis: Comparison of variables before and after the intervention. The analysis will be performed by biological and immunological effectiveness.
In this prospective cohort study the investigators will assess the prevalence and incidence of a broad range of age-related co-morbidities and their (known) risk factor among HIV-patients and HIV-negative controls. HIV might cause premature onset or accelerated aging and could therefore result in an increase of age-related comorbidities when compared with controls.
