Filter by:This is a pilot study of treatment of acute HIV infection with a once daily regimen of Emtricitabine, Tenofovir and Efavirenz. The primary objectives of this study are: 1. To determine the safety and tolerability, and the virologic and immunologic efficacy of FTC, TDF, and efavirenz given once daily to patients with acute HIV infection. 2. To assess the impact of once daily therapy combined with a standardized adherence program on treatment adherence, virologic suppression, and rate of viral load decline in blood and infectious fluids (semen, cervico-vaginal secretions). 3. To define the prevalence of genotypic and phenotypic resistance to antiretroviral agents among persons diagnosed with acute HIV infection in the Southeastern United States.
Background: - About 10,000 children in the United States have been living with HIV infection since birth. Little is known about the long-term effects of HIV infection and its treatment on the growth and development of these children. - Because of their disease, many children with HIV face additional difficulties with their health, well-being and development, such as success in school and peer relationships. Objectives: - To better understand how HIV infection and the medicines used to treat it affect the growth and development of children, adolescents and young adults who have been infected since birth or when they were very young. - To develop ways to improve the quality of life for these individuals. Eligibility: -HIV-infected patients who were followed by the pediatric HIV program in NCI as of December 2004, or an HIV-infected sibling of a participant. Design: - Periodic evaluation of pubertal development; bone mineralization; body composition and fat distribution; liver, kidney and heart status; and behavioral, cognitive and academic or vocational outcome of the study group. Evaluations include the following: - Physical examinations, including height and weight measurements and skin-fold thickness testing to measure body fat. - Review of medical records and family history. - Blood and urine tests, including pregnancy test in females who can bear children. - DEXA scans (X-ray test to measure bone strength and how much fat, muscle and bone is in the body). - Neuropsychological testing, including evaluation of language, thinking and problem-solving abilities. - Magnetic resonance imaging (MRI): Test using a magnetic field and radio waves to examine brain structure and function. - Oral glucose tolerance test: Blood sampling before and one time after the subject drinks a sugary solution to measure the body's ability to use sugar
HIV-infected children, youth, and adults have lower bone mineral density (BMD) than would be expected for HIV-uninfected people of similar age, weight and race. As the majority of perinatally HIV-infected U.S. children are entering or in adolescence, the potential for HIV-related impaired BMD during the adolescent peak of bone mass acquisition is of particular concern. The primary purpose of this study was to compare changes from pre-treatment levels of BMD of the lumbar spine after 24 and 48 weeks of alendronate treatment with placebo in HIV-infected children and adolescents.
The purpose of this randomized, double-blinded study is to test the safety of GSK1265744 and how well it works on reducing the amount of HIV in the blood. It will also look at how people react to and how a human body uses GSK1265744. This study will compare the effects of GSK1265744 and placebo. The study will consist of 1 or 2 parts to look at doses of GSK1265744. About 8 people will take part in Part 1 of the study receiving dose A. If additional dosing information is needed after Part 1, about 6 people will take part in Part 2 of the study receiving dose B.
The primary objective of this study is to compare steady-state plasma PK, safety and tolerability of GSK1265744 with and without etravirine
The purpose of this study is to evaluate the effect of GSK2448761 on CYP450 metabolic probes and to evaluate the 2-way interaction between GSK2448761 and two ritonavir-boosted protease inhibitors that are commonly used in HIV-infected subjects.
The purpose of this study is to evaluate the pharmacokinetics (what the body does to the medication), safety and antiviral activity to support dose recommendations by body weight of darunavir with low-dose ritonavir (DRV/rtv), in combination with other antiretroviral drugs (ARVs), in treatment-experienced Human immunodeficiency virus 1 (HIV 1) infected children.
Cigarette smoking is a major cause of illness among HIV-infected patients (non-AIDS defining malignancies (especially lung cancer), non-AIDS bacterial infections and cardio-vascular diseases). Approximately 50% of HIV-infected patients are regular tobacco smokers. Tobacco smoking cessation has well known benefits on mortality and morbidity in the general population where tobacco cessation assistance programs are increasingly implemented. However, smoking cessation interventions have never been evaluated among HIV-infected patients. This trial aims at evaluating the efficacy and safety of varenicline for smoking cessation compared with placebo.
We will conduct a sub-study of "An Innovative Telephone Intervention for HIV+ Smokers," (NCT00502827) conducted by Drs. Gritz, Vidrine, and others. This is a randomized, prospective trial that will evaluate a cellular phone delivered counseling intervention versus standard of care for smoking cessation. In our sub-study, we will evaluate rates of progression in atherosclerosis in HIV/AIDS patients who quit smoking versus those who continue smoking by measuring carotid intima-media thickness(CIMT) and biomarkers of atherosclerosis at time point baseline, 1 year, and 3 year. The biomarkers measured include high-sensitivity Creactive protein, homocysteine, and IL-6. We will also evaluate rates of progression of CIMT in those who quit smoking versus those who continue smoking, based on race, sex, state of HIV disease, comorbid diseases, and lipid profile.
The purpose of this study is to determine whether dapivirine gel 4789 is safe for daily use by healthy women in South Africa.
