The basement membrane is a major focus of scientific interest because of its role in a variety of diseases. In diabetes mellitus, a thickening of the capillary basement membrane results in microangiopathic lesions. To monitor the metabolism of the basement membrane protein collagen type IV (CIV) in diabetes mellitus, serum levels of CIV were measured using an enzyme‐linked immunosorbent assay (ELISA) method in 28 children with type 1 diabetes mellitus over a period of 6 years. These values were compared to serum CIV levels in 24 age and sex matched controls. In the first 3 years, serum CIV levels were normal. In the 4th year, 1 patient and in years 5 and 6, 4 patients had increased CIV serum levels. At the end of the investigation, 3 children had developed retinopathy, 6 microalbuminuria, and 2 both microalbuminuria and retinopathy. Only those patients with microalbuminuria had increased CIV serum levels. In conclusion, we suggest that CIV serum levels can be used as a marker for the development of diabetic microalbuminuria.
