Filter by:Early Lung Cancer diagnosis in a HIV-infected population with an important smoking history with low-dose CT: a pilot study: the HIV-CHEST study Objectives The main objective of this study is to evaluate the prevalence of lung cancers detected by low-dose computed tomography (CT) in a HIV-infected population with an important smoking history. Other objectives are (1) the evaluation of the types of lung cancers in this population, as well as (2) the staging of non small cell lung cancers, (3) the description of risk factors for all lung cancers, if they are numerous enough, and (4) the number of complications of diagnosis procedures during the study.
The purpose of the study is to investigate the benefits of switching away from efavirenz (part of the combination pill, Atripla®) in patients with central nervous system side effects (such as insomnia {difficulty with sleeping}, bad dreams etc). The investigators will investigate the effect of switching to Truvada (a combination pill of tenofovir and emtricitabine, the other two components of Atripla) plus raltegravir. Raltegravir is a licensed drug for HIV treatment which showed side effects were fewer in number when compared to efavirenz in 2 other clinical studies, where patients were starting HIV treatment for the first time. This study will also investigate the safety (in terms of other side effects and the routine blood tests which the investigators ordinarily use to monitor your treatment) and monitor effectiveness, your viral load and CD4 counts, when you switch treatment from Atripla® to Truvada/raltegravir.
This partially randomized phase I/II trial studies the side effects and the best dose of vorinostat when given together with combination chemotherapy and rituximab to see how well it works compared to combination chemotherapy alone in treating patients with human immunodeficiency virus-related diffuse large B-cell non-Hodgkin lymphoma or other aggressive B-cell lymphomas. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Giving vorinostat together with combination chemotherapy and rituximab may kill more cancer cells.
The purpose of the study aims is to help determine whether it is safe to change directly from efavirenz to maraviroc in patients who are stable on an efavirenz-containing regimen. The pharmacokinetics (drug levels) of efavirenz and maraviroc when efavirenz is stopped and maraviroc is started will be assessed. Both the study patients and the study team will know which treatment is being taken at all times in the study.
The primary objective of this two-phase trial is as follows: - To determine the elimination half-life of NVP in HIV positive pregnant women receiving it as a single dose in labour in addition to the ZDV and 3TC with or without seven days phenytoin (pilot PK phase) - To determine NVP resistance in HIV positive pregnant women receiving it as a single dose in labour in addition to ZDV and 3TC with or without seven days phenytoin (main trial phase) The secondary objectives of this two-phase trial are as follows: - To determine the safety of single dose nevirapine with seven days phenytoin as a part of ARV prophylaxis for PMTCT vs. single dose of nevirapine without phenytoin as a part of ARV prophylaxis for PMTCT - To determine the HIV status of the infant - To determine the safety of the ARV prophylaxis for PMTCT with seven days of phenytoin on the newborn Hypothesis: phenytoin reduces the elimination half life of SD NVP and thereby decreases development of resistance to NVP in HIV positive pregnant Tanzanian and Zambian women.
Background: - Chronic hepatitis C (CHC) is a major health problem that particularly affects individuals with human immunodeficiency virus (HIV) infection, and can lead to cirrhosis and liver failure. Standard treatment for people with HIV and CHC is a 48-week course of pegylated-interferon alfa 2a (peg-IFN) and ribavirin (RBV), but better treatments are needed for those who either do not respond to the drugs or who relapse after treatment. - Nitazoxanide has been approved by the Food and Drug Administration primarily to treat diarrhea caused by parasites, and it has been studied in the treatment of CHC infection. However, it has not been tested in persons infected with HIV and CHC co-infection. Researchers are interested in determining whether nitazoxanide is a safe and tolerable treatment for CHC in individuals with HIV. Objectives: - To assess the safety and tolerability of using nitazoxanide to treat chronic hepatitis C infection in individuals with HIV who have not responded to standard treatment for hepatitis C. Eligibility: - Individuals at least 18 years of age who have been diagnosed with both HIV and chronic hepatitis C, and who have either not responded to or relapsed after previous hepatitis C treatment. Design: - Participants will be screened with a physical examination and medical history; blood and urine tests; imaging studies; possible heart, lung, and psychological tests; and a liver biopsy if one has not been done in the past 3 years. - Participants will receive nitazoxanide, the medication being studied, to take by mouth for 4 weeks, and will provide blood samples during this time. - After 4 weeks, participants will receive the first dose of peg-IFN and RBV. Participants will have weekly injections of peg-IFN and continue to take nitazoxanide and RBV by mouth for 48 weeks. Individuals who are slow to respond to this combined CHC treatment (nitazoxanide, peg-IFN, and RBV) by week 12 will continue to have the combined treatment for an extended period, a total of 72 weeks. - Participants will have study visits to provide blood samples and have other tests two times in the first month of combined treatment, and then at months 2, 3, 4, 7, 10, 13, 19; and month 25 only in participants slow to respond to combined treatment. - Some participants who are on specific HIV treatment regimens may enroll in a substudy that will require three separate 12-hour visits for repeated blood samples and other tests during the initial 4-week nitazoxanide treatment.
Improvement in the rate of bacterial translocation may lead to a decrease in a chronic inflammatory response thereby decreasing CD4 destruction and HIV proliferation. By the addition of probiotics we hope to show a reduction in LPS leading to a decrease in chronic inflammation and therefore an improvement in immune markers.
The Study will help to compare the Quality of Life for those HIV patients that are on monotherapy with LPV/r Vs. triple therapy with a boosted protease inhibitor
The incidence of lymphomas is increased among HIV infected patients. In 70 % of cases, those are Non Hodgkin's lymphomas (NHL) and Hodgkin lymphomas (HL) in 30% of cases. In France, their incidence is estimated to 100 cases per year (data from the "Base de données Hospitalière Française sur l'Infection à VIH" (FHDH)). The main mechanisms involved in lymphomagenesis are immune dysfunction, involvement of oncogenic viruses (Epstein-Barr (EBV) and HHV8) and molecular oncogenic events. A better understanding of these different pathways, give the possibility to design specific treatments. The treatment of these lymphomas is not standardized. A prospective study of patients with HIV associated lymphoid malignancies is an innovating tool to answer epidemiological, physiopathological and therapeutic questions. We propose a prospective multicentric study of these patients. The main objectives of this prospective study are to: - evaluate the incidence, characterise clinically and histologically NHL and HL cases associated to HIV - perform an observational study of the treatment and outcome of these patients out of the context of clinical trials, - study the differentiation and activation of B-cell populations, - better understand the role of specific T cell responses in the control of EBV infection, - allow other biological studies from the ANRS group " Lymphome et VIH ". The recruitment of 40 cases per year is expected. The length of inclusions is 7 years. The follow-up will be of 2 years. Clinical, pathological and biological data at diagnosis and during follow-up will be collected. This will allow characterizing the lymphoma, the HIV infection, the antitumoral treatments and the outcome of lymphoma. Biological samples will be centralized to collect cell, DNA, RNA, plasma, serum and tumour collections (Y.Taoufik, S Prevot* ). To better understand the EBV infection and lymphomagenesis in HIV infection, we propose to follow the viral load and the molecular characteristics of EBV in PBMC, plasma and tumour (P.Morand* , V.Boyer* ), to investigate the EBV-T cell responses (G.Carcelain) and the presence and reactivation of EBV in peripheral B cells (C.Amiel* , JC Nicolas) and in tumoral samples (M.Raphael* , I.Joab* ). The other mechanisms of lymphomagenesis in HIV infection will be studied by the analysis of the sub-populations of B-cells in terms of activation and differentiation (Y.Taoufik) and by the characterization of MSI tumours (A.Duval).
The purpose of this study is to compare the body fat distribution in Human Immunodeficiency Virus-1 (HIV-1) infected patients receiving, since the beginning and for at least two years, an antiretroviral therapy based on efavirenz or lopinavir/ritonavir and a combination of tenofovir plus emtricitabine (or lamivudine).
