Active clinical trials for "HIV Infections"

Mother-to-child transmission of HIV is an important but preventable mode of infection. Prevention depends on identifying pregnant women infected with HIV and offering medications during pregnancy which can dramatically decrease the chances of transmission. Currently universal screening of all pregnant women for HIV is recommended in the province of Ontario. Unfortunately the rates of screening are still low: estimates place the average rate at 50% -60%. We believe that rates in our clinic at the Women's Health Care Centre are significantly higher in part because all our patients have a first obstetrical visit. This is an unhurried visit with a trained obstetrical nurse who offers pre-test counselling and explores reasons why patients refuse testing. We hypothesize that with this system, acceptance rates for HIV screening are significantly higher than the provincial average.

There has been an increase in incidence in sexually transmitted infections in HIV infected patients in the last years. In this study the investigators will prospectively evaluate the prevalence of symptomatic and asymptomatic infections with N. gonorrhea and Ch. trachomatis as well as the seroprevalence of Herpes simplex Type 2 infection in HIV-infected patients attending the clinic for infectious diseases at the Berne University Hospital. In addition, participants will be asked to fill out a questionnaire on sexual behaviour and sexual health. Study hypothesis: STI prevalence is high in certain risk-groups to justify screening in regular intervals.

This study is to look at things that may affect whether or not people who are HIV-infected get into medical care and stay in medical care. some of the things that will be examined include how drug use, HIV disease severity, mental health, housing, trust, feelings of discrimination, social support, relationship with provider, and patient's race and provider's race are linked with whether or not people get health care. People who are enrolled in the study will be interviewed once, and their medical records will be examined.

Interleukin-2 (IL-2) is a protein found naturally in the blood that helps boost the immune system. The purpose of this study is to provide long-term treatment and monitoring of HIV infected people enrolled in NIAID-funded studies investigating the use of laboratory-made IL-2 for the treatment of HIV infection.

This is a multicenter, open-label, non-randomized, dual-arm pilot study to investigate the prevalence of the reverse transcriptase (RT) resistance mutations, K65R/x or L74V/x, in HIV-1 plasma from subjects experiencing confirmed first-time incomplete virologic suppression during treatment with an initial antiretroviral (ARV) regimen consisting of at least 12 weeks of TDF or ABC + emtricitabine (FTC) or lamivudine (3TC) + non-nucleoside reverse transcriptase inhibitor (NNRTI) or protease inhibitor (PI). Subjects will be followed until a substantial loss of virologic or immunologic control requires a treatment switch. Confirmed first-time incomplete virologic suppression is defined as an initial plasma HIV-1 RNA response < 400 copies/mL, and subsequent virologic rebound > 400 copies/mL measured at two consecutive times. Subjects will have a screening genotype to establish adherence to their non-suppressive TDF- or ABC-containing regimen by the presence of M184V (or other treatment-related primary) mutation and to demonstrate that the evolution of treatment-emergent RT mutations can be characterized. Twenty subjects (a maximum of 10 per arm) will be enrolled at 10-20 United States (U.S.) sites. If fewer than 20 subjects can be enrolled, the study may be discontinued early by the sponsor. Equal numbers of subjects on Arm A versus Arm B will be a goal.

To obtain information on clinical practices for patients treated by Aptivus in real life

The purpose of this study is to determine how often dementia and other neurological problems occur in people with HIV. Participants of ACTG A5175 will enroll in this study.

This study is assessing the extent of spirituality in patients with HIV/AIDS and will determine the relationship between spirituality, health status, and the will to live.

The purpose of this study is to explore the association between blood pressure, HIV and/or its treatment in a cross sectional observational study.

This study will determine the amount of liver scarring (fibrosis) or liver damage in people infected with 1) hepatitis B virus (HBV, a virus that can infect the liver); 2) HIV (the virus that causes AIDS); 3) both HBV and HIV; and 4) neither HBV nor HIV. Liver fibrosis and liver damage can have many causes, including alcohol, certain medicines, exposure to some contaminated foods and infections with viruses that affect the liver (such as HBV). About 25 million people in sub-Saharan Africa are infected with HIV and about 50 million with chronic HBV, yet very little information is available on how many people are infected with both viruses and the medical implications of co-infection. Participants in Uganda s Rakai Health Sciences Program (RHSP) or Infectious Diseases Institute (IDI) clinic who are 18 years of age or older may be eligible for this study. People enrolled in the study come to the clinic for at least one visit and may be asked to return yearly. During the visit, participants undergo the following procedures: Questionnaire and a short interview about their health and quality of life. Physical examination and blood draw. The blood is tested for HBV and other factors that may suggest liver disease. Blood drawn at previous clinic visits or from other studies may also be tested. Liver evaluation using a FibroScan, a medical device that uses elastic waves to measure liver stiffness in a process similar to ultrasound scanning. For this test, the subjects lies flat on the back with the arm extended out. The tip of the machine s probe is covered with gel and placed on the skin between the ribs at the level of the right lobe of the liver. The machine produces a little tap on the skin that sends a wave out and checks how fast the wave moves. The speed of the wave indicates the amount of scarring in the liver.
