Preprandial microemulsion cyclosporine administration is effective for patients with refractory nephrotic syndrome.

Background/aims: The present study evaluated the clinical efficacy and pharmacokinetics of microemulsion cyclosporine A (ME-CyA) with modification from postprandial to preprandial administration in adult patients with refractory nephrotic syndrome.

Methods: We investigated 19 patients with refractory nephrotic syndrome who had been switched from the postprandial administration of ME-CyA to preprandial administration. The pharmacokinetics of ME-CyA were also evaluated before and 6 months after switching from postprandial to preprandial administration by serial measurement of the blood CyA concentration in 10 patients.

Pharmacokinetics of fluconazole and fosfluconazole after intraperitoneal administration to peritoneal dialysis rats.

Fluconazole (FLCZ) is an antifungal agent that is efficacious in the treatment of fungal peritonitis. Fosfluconazole (F-FLCZ) is the phosphate prodrug of FLCZ, which is highly soluble compared with FLCZ. F-FLCZ is useful against fungal peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients because it has a high water solubility.

More stable and reliable pharmacokinetics with preprandial administration of cyclosporine compared with postprandial administration in patients with refractory nephrotic syndrome.

Study Objective: To compare the absorption profile of cyclosporine after preprandial administration with that after postprandial administration, and to determine which administration time resulted in a more stable absorption profile and the timing of the drug concentration that was the most reliable marker for monitoring drug absorption.

Design: Prospective analysis.

Setting: University teaching hospital in Japan.

Infected hepatic cyst.

We describe an unusual case involving an infected hepatic cyst. An 88-year-old woman presented with acute onset of right upper quadrant abdominal pain, mild left lower abdominal pain, diarrhea, and fever. On admission, computed tomography revealed multiple hepatic cysts including an 8-cm cyst located in the left medial segment of the liver, which demonstrated a thickened wall enhanced with contrast media.
