Filter by:DMPA (depot medroxyprogesterone acetate or the 'depot' injection) is a widely used contraception. It is popular in woman with HIV as it probably still works when you take HIV drugs. HIV drugs can increase or decrease the level of other drugs (e.g. contraceptives) in your bloodstream which may make them work less well or increase side effects. It is assumed that DMPA can be given with HIV drugs there are no studies proving this. The purpose of the study is to investigate whether an HIV drug combination containing lopinavir/ritonavir affects DMPA when they are taken at the same time.
The PIVOT trial aims to determine whether a strategy of switching to PI monotherapy is non-inferior to continuing triple-therapy, in terms of the proportion of patients who maintain all the drug treatment options that were available to them at baseline after at least 3 years of follow-up, and to compare clinical events, safety, toxicity and health economic parameters between the two strategies.
With the increasing age of people living with HIV/AIDS, age-induced osteoporosis is likely to be compounded by HIV/AIDS and HAART-associated bone loss. Mechanistically, osteoclasts the cells responsible for bone resorption form under the influence of the key osteoclastogenic cytokine receptor activator of nuclear factor kappa-Β ligand (RANKL). The osteoclastogenic and proresorptive activities of RANKL are moderated by its physiological decoy receptor osteoprotegerin (OPG). Imbalance in the ratio of RANKL to OPG alters osteoclastic bone resorption and lead to osteoporosis. Activated T- and B-cells are a major source of RANKL, while normal physiological B-cells are a major source of OPG. T-cells regulate the production of OPG by B-cells. Thus changes in the immune system induced by HIV/AIDS and/or by HAART could affect B-cell and T-cells RANKL and OPG production. Indeed, data from our group shows that in an animal model of HIV/AIDS, the HIV-1 Transgenic rat, the development of osteoporosis is recapitulated as observed in HIV-infected patients, and B-cell OPG and RANKL production are concurrently down regulated and upregulated respectively. Furthermore, preliminary data in HIV-infected subjects suggests dramatic acute upswing in bone resorption following HAART initiation that peaks at 12 weeks and then declines. Based on these findings, the investigators hypothesize HAART associated bone loss is driven by immune reconstitution. Because this effect of HAART is dramatic in magnitude but short in duration, the investigators propose to apply antiresorptive agent (zoledronic acid, reclast®) to specifically spare patients from this dramatic but acute bone damage.
The investigation will be conducted for the purpose of determining the condition of occurrence of Adverse Events under the actual post-marketing use of Zithromac 600mg Tablet, verifying the therapeutic effects, detecting unknown Adverse Drug Reactions and drug interactions and determining the factors affecting safety and efficacy.
A longitudinal study on immune responses in relation to protection against clinical malaria episodes will be conducted in Apac District, Uganda. Three cohorts will be recruited: children 1 to 5 years of age (n=250), children 6 to 10 years of age (n=125) and adults 25 and above (n=125). After finger prick sampling (~300µL) and examination at enrolment, participants will be followed up for one year. Follow-up will include fortnightly active case detection and three-monthly cross-sectional surveys. Clinical malaria attacks and the associated clinical and parasitological parameters will be related to immunological profiles determined utilizing a protein microarray as a capture substratum to profile the humoral immune response against a vast number of parasite antigens. For individuals who experience a clinical malaria attack or who are diagnosed with high density parasitaemia (≥15,000 parasites/µL) during cross-sectional surveys, a 5mL blood sample is obtained to determine the diversity of parasite antigens in the population in relation to antigen recognition in the cohort.
The investigators have recently evidenced the presence of antibodies to endothelial cells and fibroblasts in patients with idiopathic or SSc-associated PAH. The investigators also have identified several target antigens of anti-fibroblasts antibodies. The objective of this study is to further investigate for the presence of antibodies to endothelial cells and fibroblasts in patients and characterize the antigen specificity of autoantibodies in patients with different types of non idiopathic and non SSc-associated PAH, such as PAH associated with HIV infection, porto-pulmonary hypertension, congenital heart diseases, systemic lupus erythematosus, mixed connective tissue disease and Sjögren's syndrome
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.
The purposes of this study are to evaluate if switching an antiretroviral medication from efavirenz (EFV) to atazanavir/ ritonavir (ARV/r) will, in a 96-week period, change: 1. the amount of fat in HIV patients with lipoatrophy, 2. metabolic lab values such as your lipid (fat) profile, glucose (blood sugar), and insulin (a hormone that regulates glucose) in HIV patients with lipoatrophy.
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.
