In 26 type I diabetics ranging in age from 18 to 65 years with a duration of illness of between 1 and 34 years the following investigations were performed: 1. case history and questionnaire; 2. neurological examination; 3. determination of the vibration threshold; 4. electroneurography of the peroneal nerve and the sural nerve; 5. determination of the cardiovascular reflexes; 6. medical examination and additional findings; 7. ophthalmological investigation. 21 patients showed evidence of sensorimotor polyneuropathy (SM-PNP), the average age of this group (41 years) being 10 years higher than in the group without SM-PNP (31 years). The values of HbA1c were pathological in 17 of 21 cases with SM-PNP, and 2 of 5 cases without SM-PNP. Retinopathy was found rarely in both groups. 13 patients showed evidence of autonomic neuropathy (ANP). The mean duration of illness (15.4 years) and the average age of patients (36.5 years) in this group was distinctly higher than in the group without ANP (mean duration of illness: 8.9 years, mean age: 31.9 years). 12 patients with ANP and 7 patients without ANP had abnormally high HbA1c levels. Diabetic SM-PNP was most frequently (in 19 of 21 cases) diagnosed by electroneurographical investigation of the peroneal nerve. In the diagnosis of diabetic ANP the anamnesis (8 positive findings) and the determination of the heart rate variation during deep breathing (7 positive findings) are complementary. Among the 13 patients with ANP, 12 also had SM-PNP, whereas among the 21 patients with SM-PNP only 12 showed evidence of concomitant ANP.
