Validation of an Isavuconazole High-Performance Liquid Chromatography Assay in Plasma for Routine Therapeutic Drug Monitoring Applications.

Background: Isavuconazole is a triazole antifungal agent for treatment of invasive aspergillosis and mucormycosis. At present, it is unclear whether a therapeutic drug monitoring (TDM) of isavuconazole would be necessary. The aim of the investigation was to validate a high-performance liquid chromatography (HPLC) assay for routine applications.

Everolimus in combination with mycophenolate mofetil as pre- and post-transplantation immunosuppression after nonmyeloablative hematopoietic stem cell transplantation in canine littermates.

The mammalian target of rapamycin inhibitor everolimus (RAD001) is a successfully used immunosuppressant in solid-organ transplantation. Several studies have already used RAD001 in combination with calcineurin inhibitors after hematopoietic stem cell transplantation (HSCT). We investigated calcineurin inhibitor-free pre- and post-transplantation immunosuppression of RAD001 combined with mycophenolate mofetil (MMF) in a nonmyeloablative HSCT setting.

Everolimus in combination with cyclosporin a as pre- and posttransplantation immunosuppressive therapy in nonmyeloablative allogeneic hematopoietic stem cell transplantation.

Everolimus (RAD001) is an mTOR inhibitor that has been successfully used as an immunosuppressant in solid-organ transplantation. Data in allogeneic hematopoietic stem cell transplantation (HSCT) is limited. This study aimed to investigate pharmacokinetics, safety, and efficacy of RAD001 in a canine allogeneic HSCT model.

Penetration of moxifloxacin into the human pancreas following a single intravenous or oral dose.

Objectives: Failure to prevent secondary infectious complications in acute necrotizing pancreatitis (ANP) is attributable in part to the limited penetration of antimicrobial drugs. As newer quinolones are particularly attractive owing to their antimicrobial activity, for the first time we studied the penetration of moxifloxacin into pancreatic tissue in patients.

Patients And Methods: In this prospective, non-comparative clinical trial, 60 patients undergoing elective pancreas resection received a single oral or intravenous (iv) dose of 400 mg moxifloxacin for perioperative antimicrobial prophylaxis.

Expression of multidrug resistance proteins in rat and human chronic pancreatitis.

Background And Aims: The expression of the ABC-transporters MDR-1, MRP1, and MRP-2 was investigated in healthy pancreas and in chronic pancreatitis tissue samples in rats and humans to evaluate their possible involvement in a multidrug resistance of the pancreas with consequences for the pharmacologic treatment of pancreatic diseases.

Methods: Human pancreatic tissue samples of healthy tissue and chronic pancreatitis were collected during pancreas surgery. In rats, the time-course of the expression of transporter proteins was studied 14, 28, and 56 days after experimental induction of chronic pancreatitis.

The penetration of moxifloxacin into the pancreas of male rats in experimental acute necrotizing pancreatitis.

Infectious complications of acute necrotizing pancreatitis (ANP) determine the extent of multiorgan failure and account for 80% of deaths. Prophylactic use of antibiotics can reduce the incidence of these complications. However, the actual indication as well as choice of drug remains a controversial matter.

Atypical pharmacokinetics and metabolism of mycophenolic acid in a young kidney transplant recipient with impaired renal function.

A juvenile, female renal transplant recipient suffered two acute rejection episodes: the first on posttransplant day 31 while taking cyclosporine, prednisone, and mycophenolate mofetil (MMF); and the second on posttransplant day 67, when she was taking tacrolimus, prednisone, and MMF. Dosage of MMF was initially started at 2 g/d (corresponding to 600 mg MMF/m(2) twice daily.), but was reduced to 250 mg/d to 500 mg/d after severe diarrhea and a paralytic ileus on posttransplant day 16.
