title: [Clinical evaluation of urinary glycyl-prolyl dipeptidyl aminopeptidase in patients with urological disease].
abstract: Urinary glycyl-prolyl dipeptidyl aminopeptidase (GP-DAP) activity was measured in 18 healthy adults and 252 patients with urological diseases. The GP-DAP activity was significantly higher in patients with prostatic cancer, bladder cancer or renal cancer and also in patients with acute prostatitis or pyelonephritis than in healthy adults. GP-DAP activity was also studied during anticancerous chemotherapy and proved to be a sensitive parameter for renal damage as are urinary N-acetyl-beta-D-glucosaminidase, alanine aminopeptidase, beta 2-microglobulin, alpha 1-microglobulin, and albumin. The analysis of tissue activities suggested that GP-DAP was located not only in the renal parenchyma but also in the prostate and seminal vesicles.
