Filter by:This study evaluates the use of topical cyclosporine 0.05% and sodium carboxymethylcellulose 0.5% for the treatment of dry eye disease in patients infected with the human immunodeficiency virus. Twenty HIV-positive-patients were selected from the Department of Infectious Diseases of the Federal University of Rio de Janeiro Hospital. Dry eye diagnosis was based on a dry eye questionnaire (Ocular Surface Disease Index - OSDI®), Schirmer I Test, break up time and 1% rose bengal staining of the ocular surface. The patients were divided into two groups with ten patients. Group I received sodium carboxymethylcellulose 0.5% drops and group II received sodium carboxymethylcellulose 0,5% drops and topical cyclosporine 0.05% for six months.
Severe combined immune deficiency (SCID) may result from inherited deficiency of the enzyme adenosine deaminase (ADA). Children with ADA-deficient SCID often die from infections in infancy, unless treated with either a bone marrow transplant or with ongoing injections of PEG-ADA (Adagen) enzyme replacement therapy. Successful BMT requires the availability of a matched sibling donor for greatest success, and treatment using bone marrow from a less-well matched donor may have a higher rate of complications. PEG-ADA may restore and sustain immunity for many years, but is very expensive and requires injections 1-2 times per week on an ongoing basis. This clinical trial is evaluating the efficacy and safety of an alternative approach, by adding a normal copy of the human ADA gene into stem cells from the bone marrow of patients with ADA-deficient SCID. Eligible patients with ADA-deficient SCID, lacking a matched sibling donor, will be eligible if they meet entry criteria for adequate organ function and absence of active infections and following the informed consent process. Bone marrow will be collected from the back of the pelvis from the patients and processed in the laboratory to isolate the stem cells and add the human ADA gene using a retroviral vector. The patients will receive a moderate dosage of busulfan, a chemotherapy agent that eliminates some of the bone marrow stem cells in the patient, to "make space" for the gene-corrected stem cells to grow once they are given back by IV. Patients will be followed for two years to assess the potentially beneficial effects of the procedure on the function of their immune system and to assess possible side-effects. This gene transfer approach may provide a better and safer alternative for treatment of patients with ADA-deficient SCID.
Confirm the safety of maraviroc when used as a component of combination antiretroviral therapy in HIV and Hepatitis co-infected patients.
The purpose of the study is to determine the feasibility of infusing a full 4-week dose of Immune Globulin Intravenous (Human), 10% in a single subcutaneous site and the amount of recombinant human hyaluronidase needed to infuse that dose with no more than mild local adverse drug reactions.
This is an investigator-initiated, two-year, randomized, controlled, single-center, open-label, pilot study comparing 3-drug highly active antiretroviral therapy (HAART) to 3-drug HAART plus raltegravir for persons with acute and early HIV-1 infection. The study will test the hypothesis that use of the integrase inhibitor raltegravir (400 mg BID orally) to inhibit the integration step of the HIV-1 life cycle in conjunction with HAART in subjects with recently acquired HIV-1 infection will decrease the number of HIV-1 infected CD4+ T-cells to a greater extent than a 3-drug HAART regimen.
The ideal anti-HIV medications for patients with advanced HIV disease is unknown. There is evidence that anti-HIV regimens that contain protease inhibitors can enhance immune function better than regimens that do not contain protease inhibitors. This is a study that will determine the difference in immune enhancement capabilities between an anti-HIV regimen that contains the protease inhibitor - lopinavir-ritonavir, and a regimen that contains efavirenz. Both medications are recommended as first line treatments for HIV-infected patients. This study will recruit HIV-positive patients that need to start anti-HIV treatment because their CD4+ T-cells are below 200. The usual threshold for starting treatment is a CD4+ T-cell less than 350. Subjects will be randomized to treatment with either an anti-HIV regimen that contains lopinavir-ritonavir or a regimen that contains efavirenz. The study will determine the difference in immune reconstitution over 24 weeks of treatment with study medications. Among the immune parameters that will be measured is the ability of each subject to respond to vaccination with the tetanus-diphtheria vaccine and the 23-valent pneumococcal vaccine. Both vaccines are also recommended for HIV-positive patients but HIV-positive patients tend to have a lower response rate to these vaccines.
A study in healthy volunteers to determine whether there is a drug interaction between GSK1349572 and the HIV protease inhibitors lopinavir/ritonavir and darunavir/ritonavir
A study to test the safety and effect of twice daily raltegravir in a diverse cohort of patients currently infected with human immunodeficiency virus (HIV), where at least 50% are African American and at least 25% are female, either having received antiretroviral drugs before or not.
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.
Influenza vaccination has proved it's effectiveness over many years of usage including HIV/AIDS patients who are immunocompromised. In those patients, however, a noted rise in HIV viral load which follows intramuscular injection of the vaccine is of unknown significance over the long run. Mesotherapy is a procedure developed and practiced in france by which a reduced and diluted amounts of antigens is being introduced by multiple intradermal injections over the torso and upper back. Mesotherapy is mainly used as a vehicle for introducing pain medicine and cosmetics.
