Clinical significance of fractional magnesium excretion (FEMg) as a predictor of interstitial nephropathy and its correlation with conventional parameters.

Background: Elevated urine Mg excretion and its correlation with histological damage in tubulo-interstitial nephropathy (TIN) were reported. Here we investigated the clinical significance of the fractional excretion of Mg (FEMg) for the prediction of TIN.

Methods: We enrolled and assessed 94 adult patients with various renal diseases diagnosed principally by renal biopsy.

Dialysate purification after introduction of automated hot water disinfection system to central dialysis fluid delivery system.

Most dialysis clinics in Japan have mainly adopted the central dialysis fluid delivery system (CDDS) to provide constant treatment to many patients. Chemical disinfection is the major maintenance method of the CDDS. Our clinic introduced an automated hot water disinfection system that used the heat conduction effect to disinfect a reverse osmosis (RO) device and dialysis fluid supply equipment.

Contribution of residual renal function on peritoneal solute transport in dialysis patients.

Background: Increased peritoneal solute transport rate (PSTR) is primarily a consequence of continuous exposure to bioincompatible glucose-based peritoneal dialysis (PD) solutions. However, relationships between increasing PSTR and dialysate glucose load remain unclear. As some PD patients with preserved residual renal function do not show increased PSTR despite long-term PD, we examined whether loss of residual renal function is associated with increased PSTR on long-term PD.
