    Abstract:
    BACKGROUND: Nephrotic syndrome due to diabetic nephropathy is presently considered an indication for pancreas-kidney transplantation even in the absence of severe renal failure. Reversal of the nephrotic syndrome has been reported, but the mechanisms of this effect are unclear. AIM: To describe the renal morphofunctional pattern and the pattern of proteinuria before and after preemptive pancreas-kidney transplantation. METHODS: Methods included quantitative and qualitative assessment of proteinuria as well as renal ultrasound and scintiscan. CASE REPORT: A 42-year-old woman with type 1 diabetes since age 24 had widespread end-organ damage. Renal biopsy (2001) showed a mainly nodular pattern of diabetic nephropathy. Following referral (1999), her serum creatinine ranged from 1.6 to 2.2 mg/dL, with nephrotic range proteinuria (glomerular nonselective, tubular complete). Renal scintiscan revealed bilateral, symmetric, well-perfused kidneys. The functional data before pancreas-kidney graft (February 2003) were: serum creatinine 1.6 mg/dL, creatinine clearance 58 mL/min, serum albumin 2.6 g/dL, proteinuria 9.1 g/d. At hospital discharge (March 2003), the creatinine was 1.2 mg/dL, the creatinine clearance 97 mL/min, the proteinuria 0.676 g/d. Two months later, the creatinine was 1.2 mg/dL and proteinuria 0.421 g/d. A renal scintiscan demonstrated the functional prevalence of the grafted kidney (77% of total function), with vital, almost completely excluded native kidneys (functional contribution, 11.5% each). Proteinuria, ranging from 0.3 to 0.6 g/d, showed a physiological pattern. CONCLUSIONS: Functional exclusion of the native kidneys by renal scintiscan gives morphological support to reversal of the nephrotic syndrome.
