Abstract
The objective of this study is to examine the influence of lipid profiles and blood pressure on the development of microvascular complications in adolescents with insulin‐dependent diabetes mellitus (IDDM) in a matched pairs study. Patients with early background retinopathy (n= 21) or microalbuminuria (n= 15) and their respective statistical twins participated in the study. Serum total cholesterol, high‐density lipoprotein (HDL) cholesterol, fasting triglycerides, glycosylated haemoglobin Alc (Hb Alc.), and systolic and diastolic blood pressure during 3 years prior to the development of early background retinopathy or incipient nephropathy were examined. The multivariate discriminant analysis demonstrated glycaemic control and HDL cholesterol to be the most important variables related to the development of retinal lesions (84% correctness), and diastolic blood pressure to be associated with microalbuminuria (57% correctness). In addition to poor glycaemic control, different factors seem to be important for the early retinal or renal lesions of juvenile IDDM.
