The activities of four lysosomal enzymes and creatinine levels were measured in the plasma and urine of 17 healthy elderly and 7 young adults. Fractional enzyme excretion (FE ENZ) values for beta-hexosaminidase (N-acetylglucosaminidase), alpha-galactosidase, beta-galactosidase and beta-glucuronidase were calculated and compared between the two groups of subjects. FE ENZ was calculated as the ratio of enzyme clearance to creatinine clearance. The FE ENZ values for alpha-galactosidase, beta-galactosidase and beta-glucuronidase between the elderly and young populations were not statistically different; however, relative to the young control group, the FE ENZ value for beta-hexosaminidase was elevated approximately 2-fold in the elderly population (P = 0.06). The mean urinary alpha-galactosidase activity for the elderly population, when expressed on the basis of creatinine, was 50% lower than that of the control group (P = 0.03), whereas the mean urinary beta-hexosaminidase activity for the elderly was significantly higher compared to the control group (P = 0.008). When data for all subjects was analyzed, no correlation was observed between the urinary excretion of beta-hexosaminidase or alpha-galactosidase and glomerular filtration rate. These data indicate that with advancing age there are changes in the tubular secretion or reabsorption of selective lysosomal enzymes, particularly beta-hexosaminidase and alpha-galactosidase. These biochemical changes may provide a means of assessing subtle progressive deterioration of renal function.
