title: Hormonal profile, blood sugar control and HLA patterns in long-term insulin dependent diabetes with and without vascular disease.
abstract: Nineteen insulin dependent diabetics with onset at 30 years of age or less and duration of diabetes of greater than 25 years were divided into two groups on the basis of the presence or absence of clinically evident vascular disease. The patients without vascular disease were characterised by a later mean age of onset, lower fasting growth hormone concentration, and a lower frequency of the unusual HLA pattern B8 without A1 compared to the diabetics with vascular complications. The level of blood glucose control assessed over the last 15 years, insulin antibody titres, plasma glucagon levels and plasma cholesterol did not differ between the two groups. Residual beta cell activity was found in only one of the 19 patients. Although this study does not exclude an effect of the degree of blood glucose control or persistence of beta cell function in the early stages of diabetes on the subsequent development of vascular disease, it suggests that genetic factors, age of onset and plasma growth hormone levels may be more important.
