[Urinary NAG and gamma-GTP activities as indicators of CDDP renal toxicity: effect of fosfomycin on CDDP renal toxicity].
Using urinary N-acetyl-beta-D-glucosaminidase (NAG) and gamma-glutamyl transpeptidase (gamma-GTP) activities as the indicator of renal toxicity, the effect of fosfomycin (FOM) on cisdichlorodiamineplatinum (CDDP) renal toxicity was studied in 10 patients with urological malignant tumors. Regimen of chemotherapy was daily 20 mg of CDDP and 800 mg of administered by drip infusion for 5 days and 40 mg of adriamycin injected in one-push on day 1. FOM was not used at 1st cure. At 2nd cure, daily 2 g X 2 of FOM was administered for eleven days from the day before CDDP administration. Urinary NAG and gamma-GTP were measured for eleven days continuously in both 1st and 2nd cure. Effect of FOM on CDDP renal toxicity was discussed by comparison of the urinary NAG and gamma-GTP activities between 1st and 2nd cure. The results showed that urinary NAG and gamma-GTP activities following CDDP administration were deeply influenced by these activities before CDDP administration and the combined therapy of FOM had tendency to reduce CDDP renal toxicity when urinary NAG and gamma-GTP activities before CDDP administration were in the normal range.
