Effects of Pancreatic Transplantation on Diabetic Neuropathy

Abstract

Reestablishment of the euglycemic state by successful transplantation of the pancreas might halt or reverse diabetic neuropathy. To test this possibility we evaluated neurologic function by clinical examination, nerve conduction studies, and autonomic-function tests in patients with insulin-dependent (Type I) diabetes mellitus before and after successful pancreatic transplantation. Sixty-one patients were studied before and 12 months after transplantation, 27 again after 24 months, and 11 again after 42 months. A control group of patients with Type I diabetes treated with insulin underwent the same studies at similar intervals — 48 patients before and after 12 months had elapsed, 21 again after 24 months, and 12 again after 42 months.
