Medline ® Abstract for Reference 86

We prospectively determined the prevalence of morbidity from the various forms of diabetic neuropathy over one year in a population of 800 patients with diabetes mellitus (336 type 1, 464 type 2 DM). Symptoms documented were: pain/paraesthesia in the feet, loss of feeling and the restless legs syndrome. We also documented the prevalence of: neuropathic ulcers, amyotrophy, foot drop, and oculomotor palsy. Autonomic symptoms documented were: impotence, postural hypotension and diarrhoea. The only symptoms reported by 100 non-diabetic control subjects were: loss of feeling in 2% and restless legs syndrome in 7%. In the diabetics; pain/paraesthesia was present in 13%, feeling loss in 7% and neuropathic ulcers in 2%. The prevalence of Diabetic amyotrophy (proximal femoral neuropathy) was 0.8%, oculomotor palsy 0.1% and peroneal nerve palsy 0.1%. Erectile impotence was present in 20%, symptomatic postural hypotension in 1% and diabetic diarrhoea in 1%. Overall; 22.9% of the population was afflicted by one or more problems resulting from neuropathy. Neuropathy was associated with older age (p<0.001), and serious retinopathy (p<0.001) in both groups of diabetics and with duration of diabetes, proteinuria (p<0.02), hypertension (p<0.01) and ischaemic heart disease (p<0.02) in type 1 diabetics.
