title: Influence of continuous subcutaneous insulin infusion (CSII) treatment on diabetic somatic and autonomic neuropathy.
abstract: Near-normal plasma daily glucose profile was induced by Continuous Subcutaneous Insulin Infusion (CSII) treatment in order to evaluate its influence on diabetic somatic and autonomic neuropathy. Twelve insulin-dependent diabetic subjects with somatic neuropathy were studied before and after a short term CSII treatment of 10 days. Four out of these subjects, all affected by autonomic neuropathy, were followed for 1 yr with controls every four months. Metabolic equilibrium was monitored by mean daily plasma glucose (MPDG) profile and by Glycosylated Hemoglobin (GHb) evaluation. Somatic neuropathy was studied assessing conduction velocity at peroneal motor (PMCV) nerve, ulnar motor (UMCV), ulnar sensory (USCV) and sural sensory (SSCV) nerves. Autonomic neuropathy was assessed by means of a battery of five cardiovascular autonomic tests: Valsalva Manoeuvre (VR), Deep Breathing (DB), Lying-to-Standing (LS), Sustained HandGrip (SHG) and Postural Hypotension (PH). Short-term CSII treatment induced a near normalization of metabolic parameters, a significant improvement in VR (p less than 0.05) and DB (p less than 0.01) values, but no changes in NCV. The prolongation of CSII treatment in 4 subjects induced a significant (p less than 0.05) improvement in VR, DB and LS values and in PMCV and UMCV after 4 months. This improvement did not increase with the longer CSII treatment (1 yr).(ABSTRACT TRUNCATED AT 250 WORDS)
