Active clinical trials for "HIV Infections"

The study of early, acute HIV infection is critical to understanding subtype-specific pathophysiologic differences, since up to 50% of acute HIV infections may be incapacitating. This study will establish whether the patient population of the Thai Red Cross Anonymous Clinic is suitable for the study of early, acute infection.

The purpose of this study is to collect data and body fluid samples from people with acute or established HIV infection and from HIV uninfected people. Data from this study will be used to better understand properties of HIV, including HIV transmission and the differences between acute and established HIV infections.

There are about 42 million people in the world afflicted with HIV or AIDS with about 1 million patients in the US. The epidemiology of orofacial pain has been reported extensively in the literature, yet the prevalence severity and level of pain affecting the head, face, neck and intraoral structures has not been explored in a population of HIV infected individuals. Pain, in general terms, is a common experience in HIV infected patients, even in the absence of cancer or opportunistic infections. There is a variation in the prevalence of pain in these individuals depending on the stage of disease, care setting, and study methods. The purpose of this study is: To investigate the prevalence of orofacial pain in HIV infected patients during routine dental clinical assessment. To study the sensory phenotype of HIV+ patients and healthy volunteers using Quantitative Sensory Testing: To detect the presence of sensory aberrations in the orofacial complex; To identify which nerve types are involved; To identify the type of orofacial pain based on both sensory testing and clinical findings. To determine psychological condition and nutrition status in patients with HIV. To find associations between inherited traits and development of neuropathic pain.

The proposed multi-site, longitudinal study will examine the correlation of substance use, mental health disorders, and social networks to engagement in care for HIV-infected adolescent females, aged 13 years, 0 months - 23 years, 11 months, and suggest ways to promote adherence and retention in treatment, care, and prevention programs. Qualitative and quantitative data collection methods will be used with index participants and network members.

To assess the prevalence and risk factors of neurocognitive impairment and psychiatric comorbidities in HIV infected patients who have undetectable viral load, have been on HAART for at least 1 year and have no history of CNS infection.

This study will use focus groups and in-depth individual interviews to explore factors that influence the decision of Hispanics and African-Americans with HIV/AIDS to participate in a research study. HIV-positive Hispanic and African-American patients 18 years of age and older who are enrolled in an NIH HIV/AIDS protocol may be eligible for Part 1, Part 2, or both parts of this study, as follows: Part 1 - Focus group Focus group participants of from six to ten people are interviewed together during a one-time, 2-hour tape-recorded session to explore how they arrived at their decision to enroll in a research study. The group discussion is led by a moderator and a facilitator. Before the session begins, participants complete questionnaires that include information about their age, race, ethnicity, education and social support. Hispanic participants also complete a questionnaire about language preference. At the end of the focus group, participants are offered to be interviewed individually, as described below. Part 2 - In-depth interview An investigator conducts a one-on-one in-depth interview with the participant while a second person observes and tape records the interview. The interview may take from 1 1/2 to 2 hours to complete. Participants who were not in a focus group are asked to complete questionnaires as described in Part 1 above.

Objectives: Evaluate differences for mortality, morbidity and the cardiovascular risk factors between HIV and non-HIV patients with an acute coronary syndromes (ACS) after a 3-years follow up.

The hypothesis of this study is that the level of adherence necessary to achieve HIV virologic suppression with a ritonavir boosted protease inhibitor regimen (i.e. lopinavir/ritonavir) is less than the 95% rate observed in the published literature with unboosted regimens.

The purpose of this study is to determine whether the addition of zidovudine (ZDV) and lamivudine (3TC) at the onset of labor and for up to seven days postpartum to single-dose nevirapine (NVP) is associated with a lower prevalence of NVP-resistant HIV compared to single-dose NVP without ZDV+3TC.

To provide early access to tipranavir and evaluate the safety and tolerance of tipranavir combined with low dose of ritonavir in patients with progressive, HIV-1 disease who have failed or are intolerant to currently approved treatments for HIV infection, who are unable to participate in another tipranavir controlled clinical trial and have an urgent need for anti-HIV treatment.
