Active clinical trials for "Immunologic Deficiency Syndromes"

To compare the efficacy, safety, and toleration of fluconazole as a single daily oral suspension for 14 days versus nystatin oral suspension 4 times daily for 14 days in the treatment of oropharyngeal candidiasis in patients with AIDS or HIV infection.

To evaluate the efficacy, safety, and durability of response of SP-303 in decreasing stool weight in AIDS patients with diarrhea over 6 days of treatment.

To assess the tolerance and toxicity profile of deoxy-3'-fluorothymidine (FLT) after multiple oral dosing for 16 weeks. To characterize the steady-state pharmacokinetics of FLT after multiple oral doses. To assess the effect of FLT on immunologic and virologic markers of HIV infection (CD4+ lymphocyte count, p24 antigen, viremia) in patients with AIDS or AIDS related complex (ARC) after multiple oral dosing for 16 weeks.

To compare two lipid emulsions in the long-term parenteral alimentation of patients with AIDS in relation to: Clinical effectiveness. Effect on immunologic function. Effect on HIV load as measured by p24 antigen levels. Effect on relative HIV infectivity.

The purpose of this pilot study is to evaluate the efficacy of Retrovir (AZT) in the treatment of AIDS-related dementia and various neuromuscular complications. HIV is both a lymphotropic and neurotropic virus which can affect both the central and peripheral nervous systems (CNS, PNS). There is evidence that the CNS and PNS may harbor the virus in a latent state, with the potential for continuous reinfection of other body systems. Therefore, effective therapeutic efforts against HIV infection should provide effective antiviral activity within the nervous system.

To compare the safety and effectiveness of fluconazole and amphotericin B as maintenance treatment for preventing the relapse of cryptococcal meningitis in patients with AIDS.

To assess the efficacy of Saccharomyces boulardii (a nonpathogenic yeast) in producing a significant reduction in diarrheal symptoms in HIV-infected patients with chronic diarrhea.

To evaluate the efficacy of oral ganciclovir in preventing progression to cytomegalovirus (CMV) disease (e.g., CMV retinitis, gastrointestinal CMV disease) in CMV-infected people with HIV infection and CD4 lymphocyte counts <= 100 cells/mm3. To evaluate the efficacy of this drug in reducing morbidity associated with coinfection by both CMV and HIV.

This is a clinical trial of gene therapy for X-linked severe combined immunodeficiency (XSCID), a genetic disease caused by defects in a protein called the common gamma chain, which is normally on the surface of immune cells called lymphocytes. XSCID patients cannot make T lymphocytes, and their B lymphocytes fail to make essential antibodies for fighting infections. Without T and B lymphocytes patients develop fatal infections in infancy unless they are rescued by a bone marrow transplant from a healthy donor. However, even transplanted patients may achieve only partial immune recovery and still suffer from many infections, auto-immunity and/or and poor growth. A recent, successful trial in France used gene therapy instead of bone marrow transplantation for infants with XSCID. This experience indicates that gene therapy can provide clinical benefit to XSCID patients. We will enroll eight older XSCID patients (1.5-20 years-old), who have previously received at least one bone marrow transplant, but still have poor T and B lymphocyte function that compromises their quality of life. Before enrollment, these subjects will have had some of their own blood-forming stem cells harvested and frozen in a blood bank. These cells have a defective gene, but a correct copy of the gene will be inserted while the cells are grown in sterile conditions outside the patient's body. To do this, the cells will be unfrozen and exposed for four days in a row to growth factors and particles of a retrovirus we have constructed and tested called "GALV MFGS-gc." Retrovirus particles will attach to the patient cells and introduce a correct copy of the common gamma chain gene into cells capable of growing into all types of blood cells, including T and B lymphocytes. XSCID patients who are enrolled in the study will receive a single dose of their own cells that have been modified by the GALV MFGS-gc treatment and also will be given another drug called palifermin to help prevent side effects from the chemotherapy and possibly try to improve the development of the T cells. After this, the patients will be monitored to find out if the treatment is safe and to see if their immune function improves. Study endpoints are (1) efficient and safe clinical-scale transduction of HSC from post-BMT XSCID subjects; (2) administration of a nonmyeloablative conditioning regimen in older patients to improve engraftment; (3) administration of a transduced HSC to eight subjects; (4) administration of KGF to improve thymic function post transplant to improve T cell development; and (5) appropriate follow-up of the treated subjects to monitor vector sequence distribution, gc expression in hematopoietic lineages, and lymphoctye numbers and function as well as general health and immune status.

The purpose of this study is to determine the immunomodulatory and antiviral effects of the glutathione-restoring dithiol, alpha lipoic acid (ALA) in HIV-infected persons unresponsive to highly active antiretroviral treatment (HAART).
