Abstract

Pancreatic transplantation is intended to normalize carbohydrate metabolism in insulin-dependent diabetics by restoring endogenous insulin release, and it is usually performed together with kidney transplantation in patients with end-stage renal failure. A major problem in these patients is the daily control of the grafted pancreas because traditional measurements do not appear to be adequate to evaluate pancreatic function. Aiming at early detection of graft failure, we have analyzed in 8 such patients and in 20 nondiabetic kidney-grafted patients (a control group) the following variables: 24-hr glycosuria (absolute values, or values after natural logarithmic transformation) and 24-hr urinary C-peptide excretion (corrected for 24-hr urinary creatinine). These measurements, considered alone, did not detect pancreatic graft failure; for instance, glycosuria can depend on immunosuppressive steroid treatment, and it was often found even in the control group. On the contrary, the ratio Ln 24-hr glycosuria: 24-hr urinary C-peptide varied from 0.00 to 0.18 in the control group and in normally working pancreatic grafts; when the pancreatic grafts failed, however, as confirmed by arteriographic evidence, histologic findings, or dynamic endocrine tests, this ratio rose far higher than 0.18, reaching values as high as 12.2. Use of this ratio provides a simple technique for daily evaluation of pancreatic graft function and for early detection of graft failure.
