The purpose of this study is to follow patients in Phase I of an inpatient study in an eight week open label assessment of piracetam in an outpatient treatment program.
To determine how zidovudine (AZT) for the treatment of HIV infection is metabolized and excreted or eliminated in patients with infected or diseased kidneys. To determine the influence of hemodialysis and establish dose guidelines. AZT is the only antiviral agent with demonstrated effectiveness in patients with severe HIV infection. Persons with HIV infection may have additional health problems, one of which is a diseased kidney due to infection of the kidney, or side effects of therapy. The benefits and risks of AZT in patients with diseased kidneys are unknown. It is hoped that this study will allow further understanding of the metabolism and excretion of AZT in patients with kidney disease. AZT pharmacokinetics will be studied in patients with mild, moderate, and severe renal disorders
To study the safety and effectiveness of foscarnet in the treatment of AIDS patients who have active infection with cytomegalovirus (CMV) that is causing inflammation of the retina (retinitis). In addition, these patients cannot be treated with ganciclovir (DHPG) because of its toxic effect on the body's blood-forming cells or because white blood cell or platelet counts were too low. CMV is a common virus, which can cause blindness and death in AIDS patients. Previous studies demonstrate that foscarnet has been effective in both AIDS and non-AIDS patients with CMV infection. Although treatment with ganciclovir (DHPG) is also effective, a significant toxicity leading to dose-limiting neutropenia (low white blood cell count) in one third of treated patients has been associated with the drug. Based on the serious nature of CMV retinitis and the lack of alternative drug therapies for DHPG-sensitive patients, the present study will evaluate the safety and efficacy of intravenous (IV) foscarnet in AIDS patients with CMV retinitis.
To determine the effect of methylprednisolone on respiratory failure in HIV-infected patients with presumed or confirmed pneumocystis carinii pneumonia who are stratified for presence or absence of respiratory failure at the time of randomization to the study.
To evaluate the additional effectiveness of an anti-inflammatory nasal spray ( beclomethasone dipropionate ) and a broad spectrum antibiotic ( cefuroxime axetil ) over decongestant ( Deconsal II ) alone, when these agents are given individually or in combination for the prevention of recurrent paranasal sinus infection in patients with HIV infection. To compare the clinical utility of paranasal sinus radiographs with computed tomograms (CTs) in the evaluation and management of HIV-infected patients with recurrent paranasal sinus infection. To determine relevant prognostic factors and the microbiologic etiology of maxillary sinusitis in this patient population. Sinusitis is common among HIV-infected patients and is likely to be recurrent or refractory to traditional therapy, particularly in patients with advanced immunosuppression. An intervention aimed at prevention of recurrent sinus disease in HIV-infected patients appears to be warranted.
The purpose of this trial is to study L-735,524, which is an inhibitor of the HIV protease enzyme. It will be used with interleukin-2 in patients infected with HIV.
The purpose of this study is to test the safety and effectiveness of two different formulations of an HIV vaccine in infants born to HIV-infected women.
The purpose of this trial is to determine the safety and immunogenicity of an HIV-1 pseudovirion vaccine given at one antigen dose alone and in combination with each of two different adjuvants using two immunization schedules. The pseudovirions are virus-like particles generated by in vitro production of HIV-1 viral proteins which are capable of assembly into particles. The presence of gag gene products in addition to envelope glycoprotein should assist in humoral and cellular immunologic responses to internal HIV-1 viral proteins. The pseudovirion vaccine has been tested in preclinical trials in mice, guinea pigs, rabbits, and nonhuman primates with good safety and immunogenicity profile.
To determine the safety and CSF penetration of combined ganciclovir and foscarnet treatment for presumed cytomegalovirus encephalitis or radiculomyelopathy. This study proposes to investigate the use of combined ganciclovir and foscarnet to maximize the antiviral regimen. Current evidence suggests that a combination of ganciclovir and foscarnet may be the most efficacious therapy and appears to be well tolerated. This study will provide key information regarding safety and CSF penetration of the drugs available for treatment of these lethal diseases. It will also provide preliminary information regarding virologic factors relevant to CMV CNS disease. The study will also provide further data about the natural history of CMV brain infection detected by a combination of symptom complex and PCR identification of CMV in CSF and the potential of semi-quantitative PCR evaluation of the CSF for the disease.
Part A: To determine the safety and pharmacokinetics of sequential single doses of cidofovir in HIV-infected children with end-organ cytomegalovirus (CMV) disease. Part B: To determine the safety (including time to progression of CMV retinitis by retinal exam), pharmacokinetics, and long-term (6 months) tolerance of multiple-dose cidofovir in HIV-infected children with CMV retinitis. Part B: To determine the effect of multiple-dose cidofovir on the virologic parameters of CMV retinitis (viral load, shedding, and resistance to antiviral agents). [AS PER AMENDMENT 1/7/98: To determine the safety, tolerance and pharmacokinetics of sequential single doses of cidofovir in HIV-infected children with CMV retinitis. To determine the safety (including time to progression of CMV retinitis by retinal exam), pharmacokinetics, and long-term (6-month) tolerance of multiple doses of cidofovir in HIV-infected children with CMV retinitis.] While the intravenous formulation of cidofovir has been approved for the treatment of CMV retinitis in HIV-infected individuals, information is limited regarding its safety and tolerance in HIV-infected children. Intravenous cidofovir requires less frequent administration for both induction and maintenance therapy of CMV retinitis than other currently available therapies. If found to be safe and well tolerated in HIV-infected children with CMV retinitis, intravenous cidofovir would add significantly to agents available to treat this debilitating opportunistic infection.
