    Abstract:
    Levels of elastin-derived peptides (EDP) were determined by enzyme-linked immunosorbent assay (ELISA) in sera of 28 children with Type 1 (insulin-dependent) diabetes mellitus (mean age 11.6+/-2.8 years, diabetes duration 5.1+/-2.5 years). None of the children had clinical or laboratory evidence of vascular complications. The children were followed over a period of 6 years, and 24 healthy children of similar age and sex served as a control group. During the investigative period, 10 diabetic patients had increased EDP levels, with 9 having been diabetic for more than 5 years and 1 patient less than 5 years. Seven of these patients developed diabetic microvascular complications. In this group, EDP were independently associated with age (r=.39, P=.047), retinopathy (r=.48, P=.034), and antibodies to advanced glycation endproducts (AGE) (r=.52, P=.018). The data of this pilot study are not strong enough to appear that EDP are a useful predictor of subsequent development of microvascular complications. This may be due to the small number of subjects, short duration of the study, manner in which EDP or the endpoints were measured, or frequency of which EDP measurements were made. Further prospective and longer studies of larger populations are needed to identify the role of EDP as an early marker for the development of diabetic microvascular complications.
