Filter by:As recommended by the Dutch Health Council, certain risk groups and health care workers in The Netherlands were vaccinated to prevent morbidity due to pandemic influenza A/H1N1. Adults were vaccinated twice with the monovalent influenza A/California/2009(H1N1) MF59-adjuvanted surface-antigen vaccine Focetria® (Novartis). The vaccination campaign was executed by general practitioners. The aim of the study is to verify whether HIV-infected individuals generate an adequate immune response after the first and after the second vaccination.
Dzherelo (Immunoxel) is an oral immunomodulating botanical agent available over-the-counter in Ukraine. After many years of laboratory and clinical testing the formulation was approved in 1997 by the Ministry of Health of Ukraine as a dietary herbal supplement, which enhances immunity against viral and infectious diseases. The goal of this study is to conduct confirmatory clinical trial in Ukraine and Mongolia for TB indications.
The Principle objective of this study is To evaluate the performance of NRA, NRA-p and REMA-p for the detection of M. tuberculosis complex from sputum samples from adult pulmonary TB suspects in a high TB and HIV prevalence setting, using LJ and MGIT culture as gold standard. The Secondary objectives are: - To measure the performance of each assay (NRA, NRA-p, REMA-p) in sputum smear-negative patients - To describe the results of the colorimetric methods in HIV-positive and HIV-negative patients - To assess the time to detection of both NRA/NRA-p, REMA-p methods. - To evaluate the feasibility of the NRA, NRA-p, REMA-p methods. - To determine the rate of contamination of the NRA, NRA-p and REMA-p assays. - To evaluate the proportion and the clinical relevance of NTM among TB suspects in a high TB and HIV prevalence setting. - To provide capacity building for TB diagnosis in Mbarara.
This research is being done to find out whether abacavir (Ziagen®) lowers the levels of ribavirin (Ribapak®) in the body of persons taking these two drugs.
This is a two-phase study that is designed to test a novel behavioral intervention to treat depression in Human Immunodeficiency Virus (HIV) adolescents and young adults. Four Adolescent Trials Network (ATN) sites will be assigned to either the Combination Cognitive Behavioral Therapy and Medication Management (COMB) treatment group or the Treatment as Usual (TAU) group. Phase I involves pilot testing of a 24-week intervention consisting of Cognitive Behavioral Therapy (CBT) and Medication Management (MM) manuals at sites assigned to the COMB treatment group. Participants enrolled at TAU sites will receive treatment for depression that is typical at that site, which may include medication management, psychosocial therapy, or a combination of the two. Psychopharmacological and psychosocial interventions will not be standardized and participants may receive any depression treatment recommended by the site clinicians while on study. Study coordinators and site clinicians, regardless of group assignment, will document depression symptoms and treatment regimens for all participants for 24 weeks. In addition, site staff and participants at COMB sites will participate in an exit interview. The findings from these interviews will be used to revise both CBT and MM intervention manuals at the end of Phase I. Phase II is a feasibility study of the revised CBT and MM manuals. Phase II involves similar procedures as Phase I; sites assigned to COMB will implement the revised CBT and MM manuals. Participants at TAU sites will receive treatment for depression that is typical at that site. As in Phase I, psychopharmacological and psychosocial interventions will not be standardized and participants may receive any depression treatment recommended by the site clinicians while on study. Depression symptoms and treatment regimens for all participants will be documented for 24 weeks. Additionally, all Phase II participants will have 2 follow-up visits at weeks 36 and 48. Again, site staff and participants at COMB sites will participate in an exit interview. The findings from these interviews will be used to revise both CBT and MM manuals at the end of Phase II.
This study will use a longitudinal, experimental design. Participants will be randomized to either the intervention or the control group. The intervention will involve cell phone support, including reminders, assessment of barriers to adherence, problem solving and referrals conducted by an Adherence Facilitator. Control group participants will participate in all on-study evaluations, except the intervention exit interviews.
This study will carry out a preliminary "proof of concept" to evaluate two types of supplemental information that would serve as an adjunct to the traditional informed consent in a Human Immunodeficiency Virus (HIV) vaccine clinical trial. These will be compared to the condition where the traditional informed consent form is used alone. Using four intervention sites, participants will be administered a standard HIV vaccine trial consent form. They will then be randomized into three conditions: 1) No supplemental information; 2) Supplemental information with 1-sided messages (emphasizes information content related to vaccine trial randomization and unproven efficacy of vaccine); and 3) Supplemental information with 2-sided messages (acknowledges the beliefs that are at odds with the information content and seeks to neutralize those beliefs through counter-argument). An interviewer-administered questionnaire (IAQ) Part 1 will be administered before the traditional HIV vaccine trial informed consent is reviewed with the participant. An IAQ Part 2 will be administered directly after the HIV vaccine trial informed consent in the control condition or after reading through the supplemental material. Debriefing interviews will be conducted with selected participants to review their understanding of the study procedures and their reactions to the supplemental materials and/or questionnaires. The proposed research is a "proof of concept" study and is therefore not designed to test hypotheses. Consequently, formal hypothesis and related power calculations to detect certain effect sizes are not required. Instead, the goal will be to enroll an appropriate number of subjects for purpose of determining the feasibility of developing a larger study of supplemental information to be used as an adjunct to the informed consent statement in HIV vaccine clinical trials and providing related descriptive statistics.
This is a phase II, open label, randomized-controlled pilot study designed to study both the efficacy and safety of salsalate in decreasing endothelial cell dysfunction, systemic inflammation, and insulin resistance in HIV-infected adults. The investigators hypothesis is that salsalate will reduce inflammation and therefore endothelial cell activation and insulin resistance. The sample size will be 40, with an equal number of people being randomized to one of two groups. The first arm will be randomized to salsalate therapy. The second arm will act as a control group. The study duration will be 13 weeks.
The objective of this study is to determine if concentrations of raltegravir in semen exceed the 50% and 95% inhibitory concentrations of HIV during the dose interval. The secondary objective is to determine the extend of raltegravir penetration into semen by obtaining semen to plasma ratios across the dosing interval, to determine the area under the concentration time curve of raltegravir in semen, and to determine the variability in the penetration of raltegravir into the seminal compartment over the dosing period.
This is a 48 week randomized, prospective, controlled, open-label, proof-of-concept pilot clinical trial. Patients with HIV-1 infection on HAART PI-based regimen will be randomized to switch from the PI to etravirine (400 mg dissolved in water every 24 hours) or to continue with the same approach. The aim of the study is to compare the virological efficacy of the etravirine-based regimen with standard PI-containing regimen.
