Active clinical trials for "HIV Infections"

The purpose of this trial is to determine if exposure to ARV-containing investigational products in IPM clinical trials will impact the natural history of HIV infection as measured by the virologic, immunologic and clinical outcomes of participants who become HIV-positive during the IPM 027 trial.

The aim of this study is to find out why HIV continues to make copies in people taking HIV drugs. The investigators want to know if the medications most people use to treat HIV get into the lymphatic tissue where HIV persists.

A Phase 4 study is to characterize the profile of low bone mineral density (BMD) in ≥ 50 year old male subjects and post-menopausal female subjects on any tenofovir disoproxil fumarate (TDF)-based regimen

This is an observational, non-comparative, multicenter, open-label study. Participants will be treated with Raltegravir according to standard clinical practice, and monitored over a total period of 96 weeks. In an extension to the study (Amendment 1), a new cohort of aging participants (≥ 50 years) will be recruited and monitored over a total period of 48 weeks. Participants who stop taking Raltegravir before the end of the 96-week period or 48-week period, respectively, will be followed up for 3 months after discontinuing the drug. The primary objective is to determine the proportion of participants with a human immunodeficiency virus (HIV)-1 viral load < 50 copies/mL after 48 weeks of treatment with Raltegravir.

Investigators in the Division of Infectious Diseases and the Departments of Biochemistry and Molecular Biology of The George Washington University Medical Center are carrying out a research study to determine why patients with Human Immunodeficiency Virus (HIV) and Hepatitis C virus (HCV) co-infection (HIV/HCV) have a more rapid and progressive course of HCV infection, leading to fatty infiltration of the liver and cirrhosis.

The study is recruiting 50 patients initiating or switching to Atripla and comparing them to 250 individuals previously followed in a prospective study of HIV+ low income individuals recruited from homeless shelters, single room occupancy hotels and free meal food lines as part of the UCSF Reach Study. Adherence will be measured through monthly unannounced pill counts and electronic medication monitors.

This study is designed to develop and evaluate a set of non-virologic diagnostic algorithms to monitor HIV-exposed children of unknown infection status for treatment eligibility during the first year of life. The results of this cross sectional study are expected to be used in development of a series of non-virologic algorithms to determining treatment eligibility among HIV-exposed children in settings where polymerase chain reaction (PCR) testing is not available and to guide the judicious use of PCR testing among HIV-exposed children in settings where PCR is available. These results will directly inform program implementation in Zambia.

Human immunodeficiency virus (HIV) infection has been associated with a variety of cardiovascular diseases. Even most industrialised countries exhibit a growing and aging population of HIV-infected patients in the majority treated with antiretroviral drugs, the investigators still do not know much about the impact of cardiovascular diseases in this group of patients. The present study is an ongoing trial that was conducted as a prospective and multicentre survey, being schemed to analyse the frequency and clinical course of cardiac disorders in HIV-infected patients.

It is difficult to detect the intestinal protozoal infections among the HIV-infected persons or travelers diarrhea by using the traditional microscopy or staining methods. The purpose of this study aimed at finding out the appropriate diagnostic methods and the infection rate of the intestinal protozoa, including the Entamoeba, Cryptosporidium and Giardia among the HIV-infected persons by using the antigen detection method and biological method. The investigators also tried to analyze the associated HIV infection status and sexual transmitted diseases (STD) including Gonorrhea, Chlamydial trachomatis, Syphilis, Genital warts and Herpes simplex virus in this study. The study will collect the blood, urine and stool samples from 200 intravenous drug user (IDU) with HIV-infected in the prisons, 400 intravenous drug user (IDU) without HIV infected and 100 intravenous drug user (IDU) with HIV infected receiving methadone maintenance treatment.

The purpose of this study is to assess retinal nerve fiber layer thickness and macular thickness measured with optical coherence tomography (OCT) on patients infected by HIV virus without ocular manifestations and to correlate these results with perimetric findings assessed by frequency doubling technology perimetry (FDT).
