Abstract
Diabetic vascular lesions and peripheral autonomic neuropathy are both closely linked to long-term metabolic control of diabetes. Transcutaneous oxygen tension (PtcO2) measurements were made to elucidate whether autonomic neuropathy disturbs the cutaneous microcirculatory blood flow, and whether long-term glucose normalization ameliorates such impairment. Twenty-eight type 1 (insulin-dependent) diabetic patients in whom clinically significant macroangiopathy had been excluded by angiography were studied, subdivided into group A (n = 14; before simultaneous pancreas/kidney transplantation (SPKT); mean age 35 years, range 22-51 years; mean duration of diabetes 24 years, (range 15-32) years and group B (n = 14; mean 31 months, range 2-101 months, after successful SPKT; mean age 35 years, range 19-56 years; mean duration of diabetes 22 years, range 14-29 years). On addition there was a group (group C) of age- and sex-matched healthy control subjects (n = 14; mean age 35 years, range 23-62 years). PtcO2 measurements included basal recordings at 44 degrees C on the leg and the foot, functional recordings at 44 degrees C after arterial occlusion of the limb for 4 min, measurements during breathing 5 l oxygen per minute and finally while standing up (stand up dP20/dt). All subjects underwent extensive cardiac autonomic testing. In this cross-sectional study the recordings of basal values and of the functional parameters after arterial occlusion and during breathing oxygen did not differ significantly between groups A, B and C.(ABSTRACT TRUNCATED AT 250 WORDS)
