Improvement of diabetic peripheral neuropathy with the portable insulin infusion pump.

A 16-year-old girl with insulin dependent (Type I) diabetes since age 9 and painful sensory neuropathy for two months was treated with a portable insulin infusion pump, allowing strict control of hyperglycemia. Within 28 days the distal motor latency in all nerves tested had improved and painful incapacitating dysesthesias disappeared. The findings suggest that strict control of hyperglycemia with a portable insulin infusion pump can successfully reverse the changes of recent onset diabetic neuropathy.
