Active clinical trials for "Immunologic Deficiency Syndromes"

The management of patients with primary immune deficiency is increasingly codified, however contraception and pregnancy have not yet extensively studied or codified, and the medical monitoring and the prevention of infectious complications thus remains at the discretion of the practitioner. The aim the research is to study the obstetric features and outcome of patients with primary immune defects.

Therapy with lopinavir/ritonavir (Kaletra) and one other protease inhibitor in Human Immunodeficiency Virus participants

A research study to evaluate the effect of aging and HIV on neurocognitive dysfunction (declining ability to process information), physical frailty and heart disease. HIV-infected participants whose virus is controlled on antiretroviral medications will be studied to determine the rates and risk factors of developing these conditions.

The aim of the study is to observe the tolerability and effectiveness of Kaletra in Human Immunodeficiency Virus/Hepatitis-B Virus and Human Immunodeficiency Virus/Hepatitis-C Virus co-infected patients.

These studies are designed to evaluate the relative efficiency of gene transfer into primitive human hematopoietic cells by comparing lentiviral and foamy virus vectors as vehicles for transfer and expression of globin genes. Normal volunteers will serve as research participants. Each will receive a 4 day course of Granulocyte-Colony Stimulating Factor (G-CSF) after which a peripheral blood apheresis will be performed to recover a mononuclear cell population enriched in primitive hematopoietic cells. The stem and progenitor cells will be purified by selection based on expression of the CD34 antigen. The CD34+ population will be cultured in vitro with various cytokines and transduced with vector particles. The efficiency of gene transfer will be evaluated in the transduced CD34+ population, in progenitors contained within that population by culture in semisolid media and in cells capable of establishing human hematopoiesis in immunodeficient mice. The level of transgene expression will be evaluated in mature hematopoietic lineages that develop in vitro or in immunodeficient mice.

Tenofovir (TDF)-containing regimens may be associated with decreasing renal function in HIV-infected patients concurrently treated with boosted PI's and/or have co-morbid conditions including diabetes mellitus, hypertension, anemia, hepatitis B, and hepatitis C.

The purpose of this study is to assess the safety data of etravirine in a natural clinical practice.

Background: - The human immunodeficiency virus (HIV) causes acquired immune deficiency syndrome (AIDS). Combination antiretroviral therapy (ART) drugs treat HIV infection. They generally decrease the amount of HIV virus in the blood (called viral load) to very low levels. This happens only if the drugs still fight HIV and if taken every day exactly as prescribed. When not taken as directed, or if the ART drugs are not strong enough, the virus can become resistant to them, and the ART will not work to control the virus. Researchers want to know how to control HIV in people who can t lower their viral load with their current ART drugs. Objective: -<TAB>To better control HIV in people who can t get a lower viral load even with ART drugs and to learn more about why the HIV is not under control. Eligibility: People at least 18 years old and with HIV. People who have been on at least two combinations of ART drugs (including current ART). People whose last two viral loads were greater than 1,000 copies/mL. Design: Participants will be screened with medical history, physical exam, and blood tests. Participants will then have a baseline visit. They will have another physical exam, blood tests, plus answer questions about what they know about HIV and ART, and how they take their ART. Participants will arrange to stay in the NIH hospital for 7 8 days. They will take their medications as usual. At the time to take the ART drugs, they will have to ask a nurse to bring them. If they forget, the nurse will bring them. Participants will meet with a doctor, pharmacist, social worker and nurse to discuss ways to help participants remember to take their drugs. Participants will have blood drawn about every other day. Researchers will study the test results. Some participants will be put on different ART drugs. If that happens, participants will have another NIH hospital stay for 7-8 days. Participants will have 4 follow-up visits over 12 weeks, then every 3 months for 2 years or more.

The purpose of this study is to evaluate tolerability of darunavir (PREZISTA) or etravirine (INTELENCE) in patients infected with human immunodeficiency virus type 1 (HIV-1) who are naïve to these medications and in patients who have experienced tolerability issues on their current or prior combination antiretroviral therapy (cART). The tolerability is evaluated by switching the patients from their previous or current combination antiretroviral therapy (cART) to either darunavir or etravirine.

The overall purpose of the study was to describe the real-life adherence, effectiveness and safety of the Kaletra Adherence Support Assistance (KASA) Program in human immunodeficiency virus (HIV)-positive patients who were receiving treatment with lopinavir / ritonavir (LPV/r; Kaletra®) in Canada.
