Active clinical trials for "HIV Infections"

HIV /AIDS is a major public health problem in Uganda. The prevention of mother to child transmission of HIV/ AIDS (PMTCT) was launched in Uganda in November 2001 and in Mbale Hospital in May 2002. Currently, PMTCT services have been integrated into mainstream antenatal care services throughout the country. Though engaging men as partners is a critical component in the PMTCT programme, their involvement has been low. Measures to increase male partner involvement in the PMTCT programmes have not been explored in Uganda. Objectives: To determine the effect of a written invitation letter to the spouses of women, attending their first antenatal visit on: (a) couple attendance at subsequent antenatal clinic visits; and (b) couple acceptance of HIV testing. Study site: The study will be carried out at Mbale Regional Referral Hospital in eastern Uganda Study design: A randomised clinical trial among 1060 (530 intervention and 530 control) new antenatal attendees. The intervention will be a written invitation letter to their spouses. Outcome measures: The main outcome measure is the proportion of pregnant women who come with their partners for ANC at the subsequent antenatal visit. Utility: The results of this study will be utilised in re-orienting the ANC services to encourage male participation and hopefully improve the uptake of the PMTCT services at Mbale Regional Referral Hospital.

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 project assesses the efficacy of an HIV prevention program with adolescent females incarcerated in the Mississippi training school for girls. Participants in both the health education control group and the HIV prevention group will increase health knowledge as a result of their participation in the health classes while incarcerated. However, participants in the HIV prevention group will increase their condom application, assertiveness, and communication skills relative to girls in the health education only group. In addition, after release from the training school, participants in the HIV prevention group will report lower sexual risk behaviors and will have lower rates of infection with chlamydia and gonorrhea during the 12-month follow-up period than participants in the health education only group.

The aim of this study is to measure the prevention of lipoatrophy in patients treated with Lopinavir/R in monotherapy versus ZDV + 3TC + ABC

The increase in pediatric HIV infection has a substantial impact on childhood mortality in the developing world. A number of recent studies suggest that as many as half or more of mother-to-child HIV transmissions in developing countries occur in late pregnancy or during labor and delivery. Interventions targeted during the perinatal period have shown to be effective and to have a significant impact in reducing transmission. The purpose of this study is to investigate the effectiveness of nevirapine (NVP) plus immunoprophylaxis or extended NVP dosing regimens in HIV-infected pregnant women and their infants during the perinatal period.

Many of the 28 million people with immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) estimated to be living in sub-Saharan Africa also suffer from malnutrition. Reproductive age women, their infants and young children are among the most vulnerable for malnutrition and progression of HIV to AIDS and mortality is increased in the malnourished, as seen in Eastern and Southern Africa. The HIV Nutrition Project (HNP) research evaluates the effect of protein and micronutrients in meat on the health and nutritional well being of Kenyan women living with HIV in rural Kenya and the health and development of their children, by means of a randomized nutrition intervention. We will determine if meat in the diets of HIV- infected women and their children (1) protects the immune system and prevents severe infection, (2) prevents the loss of body mass and enhances the quality of life among drug naïve women not yet ill enough to warrant antiretroviral drugs and (3) positively impacts growth and development of vulnerable children of the HIV-infected women when compared to those given supplements with the same amount of energy but with either soya or wheat protein. The intervention food with beef protein provides significant vitamin B12, lysine and bio-available iron, zinc and selenium when compared to the soya and wheat supplements. Deficiencies of these nutrients may hasten HIV disease progression. The findings from our project may have implications for the development of initiatives that are either sustainable or subsidized by the local, regional and/or global economies that ensure that all HIV-infected individuals have access to adequate nutrition support that includes foods that provide enough nutrients that are needed to optimize health and well-being. The knowledge gained may significantly impact other populations at high risk for decreased immune function such as those with tuberculosis and malaria. This is a 3 arm randomized design where 225 HIV-infected rural Kenyan mothers with a CD4 between 250 and 500, WHO Stage 1 or 2, and with no co-existing infections, receive with their child, a nutrition biscuit supplement daily (5 days/week) for 12 months. These women are not yet ill enough to warrant treatment with antiretroviral drugs in Kenya and therefore a food intervention may keep them healthy longer and delay the need for drugs.

Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. The current study is designed to evaluate the safety and immunogenicity of GlaxoSmithKline Biologicals' HPV vaccine 580299 in HIV infected adult females living in the Republic of South Africa. The study is double blinded, randomized for HIV positive subjects and open for HIV negative subjects. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

This Phase I study is directed at evaluating the safety profile (as a primary end-point) and the immunogenicity (as a secondary end-point) of the recombinant HIV-1 Tat vaccine in healthy, immunologically competent adult subjects without identifiable risk of HIV-1 infection.

This Phase III, double-blind, randomized, placebo-controlled trial enrolled HIV-negative women from 4 sites in 3 countries (Kenya, Tanzania, South Africa). The study's purpose was to investigate the safety and effectiveness of a once-daily Truvada® pill (compared with placebo) in preventing HIV among HIV-uninfected women at risk of becoming infected through sexual intercourse. The study population included HIV-antibody-negative women between the ages of 18-35 who were at risk of HIV acquisition through sexual intercourse. Each participant was randomized to take either a daily single oral tablet of Truvada®, which is a fixed-dose combination of emtricitabine (FTC; 200 mg) and tenofovir disoproxil fumarate (TDF; 300 mg), or an identical placebo. After enrollment, each participant was followed every four weeks. All participants were followed for an additional eight weeks after study drug was stopped. Incidence rates of HIV infection were compared between the two groups (active drug and placebo) using the intent-to-treat principle.

This is a multicenter, open, prospective and randomized study aimed at evaluating the pharmacokinetics of the tablet formulation of lopinavir/r administered in combination with two nucleoside analogs to HIV-infected pregnant women at two different dosages: Group 1 (standard dosage): 200/50 mg lopinavir/r, 2 tablets every 12 hours, plus two nucleoside analogs. Group 2 (increased dosage): 200/50 mg lopinavir/r, 2 tablets every 12 hours until the end of the second trimester of gestation (24 weeks) and 3 tablets every 12 hours in the third trimester (from 25 weeks on), plus two nucleoside analogs. Treatment will be initiated at any time between 14 and 30 weeks of gestation and will be maintained for at least 6 weeks after delivery. The objectives are: To compare the pharmacokinetic parameters of the standard and increased dosage of the tablet formulation of lopinavir/r during pregnancy. To determine whether the standard and/or increased dosage of the tablet formulation of lopinavir/r during pregnancy confers the same exposure to the drug as that observed in the same women after the end of pregnancy and in historic controls. To evaluate the transplacental passage of lopinavir/r based on the ratio between the serum concentration in maternal blood at the time of delivery and in cord blood of the two drug dosages (standard and increased) administered during pregnancy. To evaluate the tolerability of the two lopinavir/r dosages (standard and increased) during pregnancy. To describe the vertical transmission rate of HIV to the children of the pregnant women included in the study.
