Abstract
Anti-single-stranded(ss)DNA antibodies were searched for by enzyme-linked immunosorbent assay (ELISA) in the serum of 202 outpatients with non-insulin-dependent diabetes mellitus and 135 healthy subjects to investigate their prevalence in the serum of patients with type 2 diabetes and their relationship with the presence of vascular complications. Of the 202 patients 128 had vascular complications. Anti-ssDNA antibodies were observed to be significantly more frequent in the serum of patients with vascular complications (33.6%) and in particular in patients with overt nephropathy (50%) than in patients without complications (6.7%) or controls (6.7%). Anti-ssDNA antibodies have been previously described in patients with type 1 diabetes before clinical evidence of vascular disease, and their cross-reactivity with a variety of anionic biological molecules or cells, i.e. platelets and endothelial cells, assessed. It seems not unreasonable that these autoantibodies detected in patients with type 2 diabetes could be of importance in the pathogenesis or progression of angiopathy.
