We previously reported an unexpected augmentation of mycophenolic acid (MPA) levels (trough and AUC0-12) in patients receiving mycophenolate mofetil (MMF) in combination with tacrolimus versus patients receiving the same dose of MMF in combination with cyclosporin A (CsA). This finding was accompanied by a corresponding reduction of the inactive glucuronide(More)
Mycophenolate mofetil (MMF) a potent immunosuppressive agent, has recently been approved for clinical use (CellCept) in renal transplant patients in combination with cyclosporine (CsA). With the expanded use of tacrolimus (Prograf) as well in renal transplant patients, there is a lack of pharmacokinetic studies clarifying drug interactions between the three(More)
OBJECTIVES Pancreatic cancer (PC) is one of the most lethal tumors of the gastrointestinal tract. The ability to predict which patients would benefit most from surgical intervention and chemotherapy would be a great clinical tool. A large number of potential markers have been identified lately in pancreatic cancer and their clinical utilities as prognostic(More)
The Peutz-Jeghers syndrome is an autosomal dominant disorder characterized by hamartomatous polyposis of the gastrointestinal tract, melanin pigmentation of the skin and mucous membranes, and an increased risk for cancer. The incidence of surgical complications in these patients is relatively rare, and correlates with the size and location of the polyps.(More)
BACKGROUND Thrombocytopenia after orthotopic liver transplantation (OLT) is a well recognized and prevalent early postoperative complication. The etiology, as well as the effect of this phenomenon on transplant outcome, however, are vague. The aims of this study are to identify factors contributing to thrombocytopenia and to ascertain whether there is any(More)
BACKGROUND Surgery for cholelithiasis is more common in ageing patients. The use of laparoscopic cholecystectomy (LC) in older patients may pose problems because of the comorbid conditions that are concomitant with advanced age and may increase the postoperative LC complications and the frequency of conversion to open surgery. The purpose of this study was(More)
Although the role of cholesterol absorption by the gallbladder epithelium in gallstone formation is well established, the exact process is poorly understood. Potential candidates for regulation of transepithelial cholesterol transport are suggested to be two large membrane multiple ligand receptors, megalin and cubilin. We studied the expression of these(More)
OBJECTIVE To study the clinical significance of soluble c-erbB-2 in the serum of patients with colorectal cancer. METHODS Serum c-erbB-2 levels were measured by an enzyme-linked immunosorbent assay in 52 patients with colorectal cancer and in 35 healthy controls. Their association with clinicopathological features, serum carcinoembryonic antigen (CEA) and(More)
