Active clinical trials for "HIV Infections"

The purpose of the study is to look at whether changing directly from one medication for HIV (efavirenz) to a new medication for HIV (TMC125) has any effect on the levels of TMC125 in the blood, compared to when TMC125 is taken without efavirenz having been taken immediately beforehand. The study aims to help the investigators understand whether it is safe to change directly from efavirenz to TMC125 (with no gap between the treatments) in patients who need these treatments. The study will investigate the blood levels of TMC125 when it is taken both once and twice a day.

This is a randomized trial to compare the effect of standard versus enhanced risk reduction counseling on risk behavior incidence in individuals receiving PEP medications. The study seeks to 1) determine if there are equivalent changes in the incidence of self-reported risk behaviors, STD incidence, and adherence to medications in individuals who receive enhanced risk reduction and adherence counseling and those who received standard risk reduction and adherence counseling; 2) evaluate viral and host biological factors involved in sexual transmission that may either influence PEP efficacy, or themselves be negatively or positively affected by the administration of PEP medications; and 3) contribute to the CDC registry in an attempt to provide crucial data for a case control analysis to establish the efficacy of PEP for sexual and injection drug use exposures. The principal outcome will be the change in participants' number of unprotected sexual acts following administration of PEP. This is defined as the number of prior 3-month acts of high risk unprotected sex, assessed at 12 months following a course of PEP, minus the number of unprotected acts the participant reported in the 3 and 6 months prior to beginning PEP (assessed at baseline). Methods to be used consist of interview data collection, questionnaires, risk reduction and adherence counseling and source recruitment counseling (index subject).

The purpose of the study is to determine whether an abbreviated pretest/post-test CDC recommended counseling is as equally acceptable to prenatal patients as the standard strategy using prenatal care nurses and medical providers at San Francisco General Hospital [SFGH]).

A new approach to HIV prevention currently being studied includes the use of topical microbicides, substances that kill microbes. The purpose of this study is to determine the levels of tenofovir, a microbicide in gel form, in HIV uninfected pregnant women who are expecting to deliver by cesarean.

The purpose of proposed research is to implement a randomized study that will allow us to understand and address a number of key barriers to patient adherence as well as study the effects of better adherence on health and socio-economic outcomes.

The purpose of this study is to determine whether alerts independent of the ambulatory health record are more effective in eliciting physician responses and therefore have greater impact on HIV disease outcomes than traditional static alerts.

The goal of this study is to test the hypothesis that daily ingestion of a 'synbiotic' for 4 weeks will improve intestinal function, ease immune system overactivation, and increase blood CD4 count in HIV-infected individuals. A 'Synbiotic' is a mixture of probiotic bacteria and dietary fiber.

The life skills intervention model is designed to help adolescents promote their physical and mental health through cognitive and behavioral techniques (e.g., problem solving, coping, and communication skills) designed to help them achieve social and personal competencies used to manage various life challenges.

The purpose of this study is to determine the effectiveness of a stress management group intervention for people with HIV. The study will evaluate several outcomes, including perceived stress, quality of life, psychosocial factors, and physiological measures of stress.

The purpose of this program evaluation is to determine whether the "Many Men, Many Voices" HIV/STD prevention intervention is effective in reducing HIV sex risk behaviors and increasing HIV testing among African-American men who have sex with men (MSM), who may or may not self-identify as gay. The intent of this program is to support the evaluation of an existing intervention and provide feedback to the implementing organization for improved program effectiveness, not to conduct research.
