Postepy Hig Med Dosw 2017; 71:1-4 "Activity of urine arylsulfatase A in brain‑dead graft donors is a predictor of early and late graft function"

Objective: Human lysosomal arylsulfatase A (ASA) is a member of the sulfatase family. Arylsulfatase A is required to degrade sulfatides. Sulfatides occur in the myelin sheets of the central and peripheral nervous system. In this study we evaluated the urine activity of lysosomal enzyme arylsulfatase A in brain‑dead donors as a marker and predictor of short – and long‑term renal allograft function. Patients/Methods: We analyzed data from kidney recipients who received organs from brain‑dead donors. Data from 40 donors and 68 recipients were analyzed. Results: Urine activity of arylsulfatase A in graft donors correlated positively with creatinine clearance in graft recipients after transplantation: significantly after 30 days (Rs=0.38, p=0.004) and after 3 years (Rs=0.38, p=0.03), and with borderline significance after 14 days (Rs=0.25, p=0.08) and after one year (Rs=0.23, p=0.07). Conclusions: The results of this study suggest that arylsulfatase A has a protective effect on kidney allograft, and the urine activity of this enzyme in kidney donors correlates positively with graft function.
