Filter by:To determine the safety and efficacy of erythropoietin administered to patients with AIDS or advanced AIDS related complex ARC and anemia.
To determine the safety and efficacy of erythropoietin administered subcutaneously to AIDS patients with anemia secondary to their disease and/or concomitant zidovudine (AZT) therapy. Efficacy will be assessed by correction of anemia and decrease in transfusion requirements.
To evaluate the safety and efficacy of foscarnet induction treatment of cytomegalovirus (CMV) retinitis in AIDS patients who have previously suffered severe dose-limiting ganciclovir-related myelosuppression, who are ineligible for ganciclovir treatment due to myelosuppression or who have clearly failed to have a therapeutic response to ganciclovir therapy. To assess the duration of clinical response. To evaluate the effect on quantitative CMV cultures of blood and urine. To determine the effect on recovery of HIV p24 antigen capture direct from plasma.
To compare the effects of megestrol acetate and placebo on body weight, anorexia, cachexia, calorie intake, and nutritional parameters of patients with a confirmed diagnosis of AIDS. To characterize dose response in relation to weight gain. To determine whether megestrol acetate relative to placebo improves the perception of well-being among AIDS patients with cachexia. To evaluate megestrol acetate's effect on immune function via skin test reactivity, T4/T8 ratio, and total lymphocytes.
The use of ganciclovir (DHPG) in combination with interferon beta to prevent relapse of cytomegalovirus retinitis in patients with AIDS. While early clinical trials have shown that 30 mg/kg/week of DHPG is usually sufficient to delay or prevent relapse, neutropenia is a common dose-limiting problem in about 50 percent of patients. Since in vitro data have suggested that there is synergism between DHPG and interferon beta against cytomegalovirus, a reduced dose of DHPG in combination with a low dose of interferon beta may prevent relapse without causing neutropenia. If remission can be maintained with low-dose DHPG and interferon beta, maintenance therapy with a moderate dose of interferon beta alone will be evaluated in a subsequent protocol.
The objective of this clinical trial is to determine whether long-term oral dosage of ribavirin delays development of symptomatic HIV disease in HIV antibody positive subjects who are completely asymptomatic (CDC classification group II), who have only the lymphadenopathy syndrome (CDC classification group III), or who have clinical symptoms but not severe HIV disease as defined by CDC classification, and whether the dosage regimen is safe and tolerable in these subjects.
The objectives of this study are to determine the effects of isoprinosine in patients diagnosed as having unexplained generalized lymphadenopathy. Variables to be examined will include: Signs and symptoms: - Lymphadenopathy. - Fever. - Weight loss. - Occurrence of opportunistic infections. Cell-mediated immune system parameters: - T-helper cell (OKT4) numbers and proportions. - T-suppressor cell (OKT8) numbers and proportions. - Natural killer (NK) cell activity. - Lymphocyte blastogenic response to phytohemagglutinin (PHA). - Lymphocyte blastogenic response to pokeweed mitogen (PWM). - Immunoglobulin (IgG, IgA, IgM, IgE, IgD) profile. - Circulating immune complexes. Infections characteristically associated with AIDS, such as Candida albicans, Pneumocystis carinii pneumonia, Cytomegalovirus, Herpes simplex, Cryptococcus, Histoplasma, Toxoplasma, Cryptosporidium, Mycobacterium avium- intracellulare, Legionella, and Isospora. Safety parameters: - Blood chemistry including serum uric acid (PurposeA-12). - Complete blood count (CBC). - Platelet count.
The objective of this Phase III, randomized, double-blind, placebo-controlled study in patients with immunologic deficiency is to determine the effect of Isoprinosine in producing an immuno-restorative response within the study observation period (including the 2-month period following cessation of the 28 days of treatment), measured by one or more of the following immunological parameters: - Increase in natural killer (NK) cell activity. - Increase in total T-cells (OKT-11). - Increases in absolute number and percentage of T-helper cells (OKT-4).
To evaluate the effect of Isoprinosine in patients diagnosed as having AIDS relative to: Laboratory (immunologic defects): - Comparison of total helper and suppressor T-cell numbers among the groups. - Comparison of changes in natural killer cell activity. - Comparison of other laboratory findings among the groups. Clinical changes: - Comparison of the frequency of opportunistic infections among the groups. - Comparison of the frequency of the development of AIDS-related malignancies. - Comparison of other clinical manifestations relative to severity and time of onset.
To compare the safety and effectiveness of fluconazole with that of placebo as maintenance treatment for preventing the relapse of cryptococcal meningitis in patients with AIDS.
