The purpose of this study is to look at the safety and effectiveness of a pill called Trizivir that is a combination of three anti-HIV drugs (zidovudine, lamivudine, and abacavir). Zidovudine and lamivudine are often given combined in one pill (Combivir). In this study, Trizivir will be compared to Combivir plus abacavir.
The purpose of this study is to see if it is effective to add an HIV vaccine (Remune) to the anti-HIV drug combination of Combivir (zidovudine plus lamivudine) and nelfinavir.
The purpose of this study is to see how effective and safe it is to give 1 of the 3 following treatments to patients who may not have received anti-HIV treatment: 1) lamivudine (3TC)/abacavir (ABC)/stavudine (d4T); 2) 3TC/ABC/efavirenz (EFV); or 3) 3TC/ABC/amprenavir (APV)/ritonavir (RTV).
RATIONALE: Antiemetic drugs such as granisetron may help to prevent nausea and vomiting in patients treated with chemotherapy. PURPOSE: Randomized phase III trial to compare the effectiveness of granisetron with that of a placebo in preventing nausea and vomiting after chemotherapy in patients who have malignant disease.
There is significant evidence that HMG-CoA reductase inhibitors, a commonly used class of cholesterol lowering medications, reduce the risk of death from coronary disease. Although these medicines lower cholesterol levels, other studies suggest that they have an additional effect on improving blood vessel functioning. It has also been shown that consumption of a fatty meal temporarily alters blood vessel functioning, causing endothelial dysfunction. This study will examine if pravastatin, an HMG-CoA reductase inhibitor, improves blood vessel functioning after a fatty meal. We plan on enrolling 32 subjects, aged 18-40 years, who are healthy with no history of diabetes, smoking, high blood pressure, or heart disease. These subjects will be randomly assigned to initially receive four days of pravastatin or an inactive substance, and then crossed over to the other group. Blood vessel functioning will be monitored by a technique called flow mediated vasoactivity, which uses ultrasound measurement of the forearm artery and its response to temporary occlusion. This primary measure of flow mediated vasoactivity will be done before and after consumption of a fatty meal. We hope to show that treatment with pravastatin prevents the blood vessel dysfunction known to occur after a high fat meal. Secondary outcomes will include measurement of endothelin-l, a mediator of blood vessel functioning, and assessment of changes in lipid profiles. If pravastatin does prevent endothelial dysfunction in this setting, it could lead to further studies about their use in more acute medical settings, including heart attacks or strokes.
The purpose of this study is to see if it is safe and effective to give indinavir plus ritonavir plus 2 NRTIs to HIV-infected patients who need early intervention treatment.
The purpose of this project is to pilot a new scale, The Desperation Scale, in a sample of young adolescents (aged 10-16) seen in the pediatric emergency room who require a psychiatric consultation. The proposed study is designed to assess the psychometric properties of this new scale and to provide information about the cognitive state of young suicidal individuals. It is hypothesized that this scale will be able to discriminate between those who are suicidal and those who are not. Data obtained in this pilot study will provide information about the usefulness of the construct of desperation and will guide future projects aimed at the assessment and treatment of suicidal individuals. The use of cognitive factors to predict suicidal behavior is appealing because they allow the clinician to tap into an individual's perception of his/her life circumstances. However, we believe the popular conceptualization of suicide as a result of "hopeless" thinking ignores an important aspect of suicidal behavior-the motivation to escape. We propose that a model of suicidal behavior that includes escape motivation, which we call the desperation model, will be better able to predict suicide than existing measures. We conceptualize desperation as consisting of three core elements: a sense of entrapment, feelings of anxiety/agitation, and a sense of time urgency. The current pilot study will test a 35-item scale that assesses these three elements of desperation. A pilot study of the Desperation Scale is currently being conducted at the Cornell University Medical Center (P.I. P.M. Marzuk) with depressed, adult inpatients. Our study is original in its use of the scale with an adolescent population and its focus on patients in the emergency room, when they are presumably in a "purer" suicidal state. It is hypothesized that those who are admitted to the emergency room for recent suicidal behavior will endorse feelings of entrapment, anxiety, and time urgency.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of BMS-188797 in treating patients who have advanced solid tumors that have not responded to previous treatment.
We hypothesize that ingested human recombinant interferon-alpha (hrIFN-a) will prolong the "honeymoon" period and enhance B cell survival in type 1 diabetes in a phase II randomized, placebo-controlled, double-blind clinical trial. We have demonstrated that ingested IFN-a prevents type 1 diabetes in the NOD mouse, prolongs the "honeymoon" period in newly diagnosed type 1 diabetics, and delays murine islet allograft rejection. The natural history of type 1 diabetes is unique for a phase frequently referred as the "honeymoon," a period in which the insulin need becomes minimal and glycemic control improves. The B cell (the insulin producing cell) partially recovers. However, as with all honeymoons, they end and the patient becomes completely insulin-deficient. The general consensus of the international diabetes community is to test potential preventive therapies for type 1 diabetes in newly diagnosed patients. Prolongation of the honeymoon as the reversal of the disease is considered a positive result. In this phase II randomized, double-blind, parallel-design clinical trial we will determine whether ingested (oral) human recombinant IFN-a will prolong the "honeymoon" period and increase counterregulatory anti-inflammatory cytokine(s). We will determine the safety and efficacy of 30,000 units ingested hrIFN-a vs placebo in eighty patients with newly diagnosed type 1 diabetes in a phase II trial for one year. Primary outcome measures will be a 30% increase in C-peptide levels released after Sustacal stimulation at 3, 6, 9, and 12 months after entry. Secondary outcome will be decreasing titers of islet cell antibodies (ICA). If successful, a larger and longer phase III trial of prevention of type 1 diabetes in high risk patients will be undertaken. We will also determine if ingested hrIFN-a increases IL-4, IL-10 or IFN-a production in peripheral blood mononuclear cells (PMNC) from patients with recent onset type 1 diabetes.
Enterococci, especially vancomycin resistant enterococci (VRE), are increasing in prevalence in many hospitals in the United States. Patients undergoing liver transplantation are at particular risk for developing infection due to VRE. The effect of prior colonization with VRE on the outcome of liver transplantation is unknown. This prospective study will ascertain the prevalence of gastrointestinal colonization with vancomycin resistant enterococci among patients awaiting liver transplantation at the University of Michigan Health System. Risk factors for acquisition of the organism, natural history of colonization and outcome in colonized patients will also be determined. All patients currently listed on a priority waiting list for liver transplantation at UMHS will be invited to participate. Patients will receive a standardized letter from their primary gastroenterologist describing the rationale for the study. Patients will be contacted by telephone by a member of the study team in order to arrange an appointment in the GCRC at the time of their regularly scheduled Transplant Clinic appointment in order discuss their potential participation in the study. Patients who give informed consent, will be interviewed using a standard interview questionnaire. Demographic and historical data relevant to the risk of VRE colonization will be collected during the interview. A sample will be obtained via rectal swab for culture. Rectal swabs for culture and collection of information on the standardized questionnaire will be repeated every six months while the patient is awaiting liver transplantation. When a patient undergoes liver transplantation, a culture will be obtained at the time of admission and weekly after post-operatively until discharge. All patients will be followed for 60 days after transplantation to assess several primary outcomes, including operative and post-operative complications, VRE infection and mortality. Rectal swabs will be the only procedure performed for the purposes of this study. Culture results will not be made available to the transplant team in order to avoid bias in clinical care. All data will be entered into an electronic database. GCRC statisticians will assist in the analysis of risk factors and outcome analysis.
