✦ Synopsis

The prevalence of islet cell antibodies in children with Type 1 (insulin-dependent) diabetes was determined in a cohort of 678 children. The natural course of islet cell antibodies was followed in 375 children at 1 year, 252 and 135 children after 2 and 3 years respectively. Islet cell antibodies were determined by indirect immunofluorescence on cryostat sections of human pancreas. At diagnosis of diabetes 85% of the children had detectable islet cell antibodies (mean titre 10.4). After 3 years 62% of the children were still islet cell antibody positive (mean titre 2.9) indicating a greater persistence of islet cell antibodies than described in earlier studies. In this large cohort a significant correlation between islet cell antibody prevalence or persistence and sex, age or HLA-DR type was not observed except for a faster loss of islet cell antibodies in very young boys and in patients lacking HLA-DR types 3 and 4. Complement fixing islet cell antibodies correlated with high titre islet cell antibodies. Greater persistence of islet cell antibodies was seen for cases with high antibody titre and in children with diagnosis of diabetes during the first half of the year.
