Filter by:This is a cluster randomized trial comparing the integration of family planning services into HIV care and treatment programs versus the standard referral for family planning services outside of HIV care and treatment programs within Suba, Kisumu East, Rongo and Migori districts in Nyanza province.
The purpose of this study is to investigate the extent by which intake of 20 mg once daily (q.d.) omeprazole influences the levels of TMC278 in the blood after intake of 25 mg q.d.. This study also investigates - in case levels of TMC278 are reduced when co-administered with omeprazole - whether a double dose of TMC278 (50 mg q.d.) or a separation of intake of both drugs by 12 hours may circumvent a decrease of TMC278 levels in the blood below the clinical effective concentration. Omeprazole is prescribed to reduce the production of gastric acid. Since TMC278 requires gastric acid to be properly dissolved and taken up in the blood circulation, intake of omeprazole has an influence on the levels of TMC278 in the blood circulation. This effect has been revealed in a previously conducted clinical trial, using the combination of 150 mg TMC278 q.d. and 20 mg q.d. omeprazole. The currently proposed study will also further explore the relationship between the levels of TMC278 in the blood at several time points and the acidity of the stomach. Also the short-term safety and tolerability of co-administration of omeprazole 20 mg q.d. and TMC278 25 mg q.d. will be assessed.
An open-label, 3-period, fixed-sequence study in a panel of 18 HIV-infected patients on MK0518 as part of a stable treatment regimen for HIV.
Randomised study comparing two pneumococcal vaccination strategies in HIV-infected adults with moderate immunossupression (CD4 between 200 and 500 cells/uL and viral load under 5logs), one with conjugated heptavalent vaccine(Prevenar, Wyeth-Lederle) followed by polysaccharide vaccine 4 weeks after (Aventis-Pasteur), and two with one dose of polysaccharide vaccine. Determination of secondary effects related to both vaccines and determination of antibody concentration (ELISA) and avidity (ELISA with thiocyanate) and opsonophagocytosis killing activity against the seven serotypes included in the heptavalent vaccine before vaccination, at 4 weeks, at 8 weeks, at48 weeks and 96 weeks. A sample of 220 HIV-infected adults (110 in each group) will be needed to detect differences of 10% for a type I error o 5% for a limited population of 2500 HIV-infected adults. The main hypothesis are :the immunogenicity of pneumococcal vaccination with conjugate and polysaccharide vaccines is superior to immunogenicity induced by polysaccharide vaccination alone(antibody concentration), the avidity and opsonophagocytosis induced by two vaccines is better than the one after polysaccharide vaccine alone, both vaccinations are safe.
Main objective: To study and validate a questionnaire measuring treatment adherence in patients with Hepatitis C virus (HCV) infection. Design of the study: Multicentric, prospective, epidemiological study in the field of usual clinical practice.
Recent research as suggested that use of the HIV medication abacavir (Ziagen, or co-formulated with lamivudine as Epzicom) may increase risk for heart disease, though findings from multiple studies have been inconsistent. This pilot study will examine vascular function, a marker of heart disease risk, among patients taking abacavir as part of their HIV medications and are then randomized to: 1) switch to tenofovir, another HIV medication, or 2) continue to take abacavir.
The purpose of this research is to determine the effectiveness of the novel H1Nl influenza (inactivated/killed formulation) vaccine among both HIV-infected and HIV-uninfected persons. The administration of the H1Nl vaccination is not part of the study's procedures, but is being given as part of routine care.
The purpose of this study is to compare plasma and intracellular pharmacokinetic parameters of raltegravir 800 mg administered once daily in HIV infected patients.
Approximately 30 percent of new HIV infections in the Unites States occur in women, with a disproportionate number occurring in women of color. This observational study has been designed to help determine the HIV incidence among women in the study communities as well as to identify steps that women can take to lower their HIV-infection risk.
The purpose of this study is to determine the non-inferiority in the efficacy of DRV/r (900/100 mg) monotherapy at 48 weeks versus LPV/r (400/100 mg) as simplification strategy in subjects with sustained viral suppression on stable PI or NNRTI-antiretroviral regimens.
