Neuropathy in type 1 diabetic renal transplanted patients.
This study was undertaken to study the changes in neuropathy in type 1 diabetic patients with end-stage renal disease (ESRD) after renal transplantation. From April 2007 to June 2010, 30 renal transplanted patients with type 1 diabetes mellitus (RT) and 30 type 1 diabetic patients with ESRD were enrolled in this study. Electroneurodiagnostic tests of peroneal, sural, ulnar, and median nerves were performed. Nerve conduction velocity (NCV), compound motor action potentials (CMAPs), and sensory nerve action potentials (SNAPs) were analyzed at 6, 12, and 18 months after renal transplantation. The NCV improved in the RT group in 18 months of the follow-up period (P <0.01 versus baseline). This parameter worsened significantly in the control group throughout the study period (P = 0.03), but in the cross-sectional analysis between the groups, we could not find any remarkable differences (P = 0.07). Both SNAP and CMAP amplitudes improved in the RT (SNAP Sural = 0.04, SNAP Median = 0.01 and CAMP Peroneal = 0.03, CAMP Ulnar = 0.02) but worsened in the control group (SNAP Sural < 0.001, SAP Median < 0.01 and CAMP Peroneal < 0.01, CAMP Ulnar < 0.01). Comparison of both groups did not show any significant statistical changes. Electroneurodiagnostic values improved after renal transplantation in type 1 diabetic patients with ESRD, but cross-sectional analysis did not reveal statistically significant differences between the studied groups.
