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 determine the efficacy of Stealth liposomal doxorubicin hydrochloride (DOX-SL) in the treatment of severe AIDS-related Kaposi's sarcoma (KS) by comparison with the established therapy ABV: Adriamycin (doxorubicin)/bleomycin/vincristine. To evaluate the safety and tolerance of DOX-SL compared to ABV in a population of AIDS patients with severe KS.
Incomplete Closed Protocol
To evaluate the safety of single and multiple doses (28 daily doses) of 9-[2-(R)-[[bis[[(isopropoxycarbonyl)- oxy]methoxy]phosphinoyl]methoxy]propyl]adenine fumarate (PMPA) prodrug administered orally to HIV-infected patients. To determine the pharmacokinetics of single and multiple doses of PMPA prodrug when administered orally to HIV-infected patients. To evaluate the anti-HIV activity of PMPA prodrug, as demonstrated by increases in CD4 cell counts and decreases in HIV RNA, when administered orally as a single dose and daily for 4 weeks to HIV-infected patients with CD4 cell counts of 200 or more cells/mm3.
The purpose of this study is to see if it is safe and effective to give CPI-1189 to patients with AIDS dementia. Advanced HIV infection can cause AIDS dementia (brain damage due to HIV leading to loss of memory and muscle control). CPI-1189 may be able to postpone AIDS dementia or slow it down.
The purpose of this study is to see if it is safe to give indinavir (IDV) and ritonavir (RTV) in combination with stavudine (d4T) and lamivudine (3TC) to HIV-positive patients who have never received anti-HIV therapy. This study will look at the effectiveness of this drug combination and side effects.
RATIONALE: Fludarabine may be an effective treatment for graft-versus-host disease caused by bone marrow transplantation. PURPOSE: Phase I/II trial to study the effectiveness of fludarabine in treating patients who have chronic graft-versus-host disease that has not responded to steroid therapy.
RATIONALE: Antiemetic drugs may help to reduce or prevent nausea and vomiting in patients treated with radiation therapy. It is not yet known whether lerisetron is more effective than granisetron in preventing nausea and vomiting. PURPOSE: Randomized phase III trial to compare the effectiveness of lerisetron with that of granisetron in preventing nausea and vomiting in men who are being treated with radiation therapy for stage I seminoma.
The two major types of diabetes are type 1 and type 2 diabetes. Although most patients with type 2 diabetes are older than age 40, type 2 diabetes has been reported with increasing frequency among patients under the age of 20. This form of diabetes has been called type 2 diabetes of youth, abbreviated type 2Y. Little is known about the etiology of type 2Y; however, clinicians believe that it occurs most commonly in obese children of particular ethnic groups. A positive family history appears to be one major risk factor for developing type 2Y diabetes. The individual contribution of ethnicity, obesity, and genetics to type 2Y have yet to be elucidated. There is no consensus regarding treatment with type 2Y diabetes. Observation of our Hispanic patients in the Houston area reveals a large number with type 2Y. The major purpose of this study is to examine the genetic and environmental risk factors such as family history, ethnicity, and obesity in Hispanic children with type 2Y diabetes. SPECIFIC AIMS: 1) To examine the genetic and environmental risk factors and clinical signs associated with type 1 diabetes and type 2 diabetes of youth. 2) To compare the efficacy of the treatment modalities, insulin and oral agents, in type 2Y patients. METHODS: We will undertake a retrospective case study, to include a review of hypothesized risk factors in all the medical records of pediatric diabetes patients seen at University of Texas. We anticipate that approximately 200 patients with type 1 diabetes and 30 patients with type 2Y diabetes will be identified. A Sustacal challenge test will be done in patients with a suspected diagnosis of type 2Y in order to confirm the clinical diagnosis. Parents will be contacted by phone for a detailed pedigree intake. Type 1 and type 2Y patients will be compared for each of the studied features. A retrospective review of diabetes type 2 therapies used in type 2Y patients will be undertaken through further examination of the medical records in order to compare insulin treatment to oral agents. We will also test a subset of the patients for the gene identified in adult Hispanics with type 2 diabetes.
The overall purpose of this research is to develop and use a blood test to better understand how quickly the viral drug ganciclovir works to clear infection with the CMV virus (Cytomegalovirus) when it occurs. This test will potentially let doctors know early in the course of therapy when a virus is not responding well to the therapy and could therefore be resistant to the drug. The target population of this study will be primarily kidney and lung transplant patients with CMV detected in the blood, although other patients may also be included if they meet criteria. The study will be divided into two phases. Phase I will evaluate a small number of exploratory patients initiating ganciclovir therapy and will require frequent blood sampling to obtain detailed information regarding the kinetic response of the virus to therapy. This information will be analyzed to help guide decisions regarding the number and frequency of blood samples needed in the larger phase II portion of the study. Strains will be characterized using phenotypic and genotypic methods to determine the presence or absence of mutations potentially responsible for the resistance.
