title: Continuous subcutaneous insulin infusion in the management of painful diabetic neuropathy.
abstract: Nine patients with diabetic neuropathy were treated as outpatients with continuous subcutaneous insulin infusion (CSII). Painful symptoms were scored on a 10-cm horizontal graphic rating scale; motor conduction velocity (MCV) was measured in the median and peroneal nerves; and vibration perception threshold (VPT) was recorded in the great toes. All investigations were repeated after 6 wk and at the completion of 4 mo of CSII. Improved diabetic control was confirmed by significantly lower mean blood glucose levels, M-values, and glycosylated hemoglobin. Symptomatic relief was noted by all patients and was accompanied by a significant improvement in pain scores. There was also significant improvement in VPT and MCV after 6 wk of CSII, which was maintained throughout the 4-mo period. However, sensory studies in the median nerve showed no significant changes during the study. It is concluded that strict glucoregulation is indicated in all cases of symptomatic diabetic neuropathy. It remains to be seen whether strict diabetic control from diagnosis will lead to a reduction in the incidence of this complication.
