The aim of the present study was to test whether proinsulin autoantibodies (IgG-PAA), insulin autoantibodies (IgG-IAA), and islet cell antibodies (ICA) may be used to identify subjects at risk for Type 1 diabetes. Pre-diabetic sera from 18 individuals who later developed diabetes were tested. Results were compared with 18 age-, sex-, and HLA-DR-matched non-diabetic control subjects from families with Type 1 diabetes. At a mean of 2.4 yr before the onset of diabetes, ICA were found in 13 patients (vs 0 control subjects, p less than 0.001), ELISA-determined IgG-IAA in 8 patients (vs 1 control subject, p less than 0.05) and ELISA-determined IgG-PAA in 4 patients (vs 2 control subjects, NS). ELISA-determined IgG-PAA do not appear to be useful predictors of the future development of Type 1 diabetes.
