BACKGROUND Ischemia/reperfusion injury (I/R injury) to the liver can occur in low-flow states associated with trauma and shock and surgical procedures such as liver transplantation. Recent studies have shown that the administration of the female sex hormone 17-beta-estradiol after trauma-hemorrhage in animals restores depressed cardiac, hepatocellular, and(More)
The influence of ethnic origin on organ donation and renal allograft survival after renal transplantation has been controversial. Several large studies have reported inferior renal allograft survival in black recipients, whereas others have reported equal survival. However, the issue of race as it relates to organ donation, patient referral, and patient(More)
BACKGROUND Induction therapy with daclizumab has been shown to be efficacious in the prevention of acute rejection in kidney transplant patients. The routine use of antibody induction therapy in liver transplantation has not gained widespread acceptance, except in the cases of renal insufficiency. The recent approval of daclizumab prompted us to initiate(More)
BACKGROUND Tolerance is gaining momentum as an approach to reduce lifelong immunosuppressive therapy while improving transplant longevity. Anti-CD3 immunotoxin (IT), FN18-CRM9, has potential to induce tolerance owing to its exceptional ability to deplete sessile lymph node T cells. However, if initiated at the time of transplantation, alpha-CD3-IT alone(More)
Ischemia/reperfusion (IR) injury in transplanted livers contributes to organ dysfunction and failure and is characterized in part by loss of NO bioavailability. Inhalation of NO is nontoxic and at high concentrations (80 ppm) inhibits IR injury in extrapulmonary tissues. In this prospective, blinded, placebo-controlled study, we evaluated the hypothesis(More)
STUDY OBJECTIVES To compare the effects of four techniques for preventing or blunting the hypertensive response to the insertion of Mayfield headrest skull pins: intravenous (IV) alfentanil (ALF), esmolol (ESM), thiopental sodium (TPL), and local anesthesia using plain lidocaine (Xylocaine; XYL). DESIGN Randomized open study. PATIENTS 40 adult patients(More)
During evaluation for liver transplantation, a 63-year-old man with cirrhosis secondary to hepatitis C was diagnosed with severe aortic stenosis (aortic valve area, 0.87 cm(2)) and coronary artery disease. A combined procedure involving aortic valve replacement (pericardial xenograft), coronary artery bypass surgery, and orthotopic liver transplantation was(More)
Decreases in endothelial nitric oxide synthase derived nitric oxide (NO) production during liver transplantation promotes injury. We hypothesized that preemptive inhaled NO (iNO) would improve allograft function (primary) and reduce complications post-transplantation (secondary). Patients at two university centers (Center A and B) were randomized to receive(More)
BACKGROUND Mycophenolate mofetil (MMF) prolongs allograft survival in experimental animals, prevents acute rejection in humans, and has recently been approved for use in renal transplantation in combination with cyclosporine. Tacrolimus (Prograf) has been shown to be effective for the prevention and treatment of allograft rejection in liver transplantation.(More)
UNLABELLED We conducted a prospective, randomized study to determine the efficacy of conjugated estrogen in reducing blood product transfusion during orthotopic liver transplantation (OLT). Patients undergoing OLT were included in the study. Only those having a reaction time of more than 30 mm or 15 min (19 -28 mm) on computed thromboelastography (CTEG) at(More)
