title: [Total IgE synthesis in diabetic children].
abstract: Antibodies (ICA and other organ-specific and non-organ-specific antibodies), HLA histocompatibility antigens and serum IgE levels were analysed in 27 diabetic children aged 2 to 14 years. The results obtained are as follows : 59% of examined subjects had ICA; the HLA-B8 incidence in our diabetic patients was significantly higher (p less than 0.0005) than in normal population; serum IgE levels were higher than +1 SD in 67% of patients; this percentage reaches 76% in diabetics with ICA and 86% in diabetics with ICA and HLA-B8. Enhancement of IgE production could be the consequence of a reduction in the number and/or function of suppressor T lymphocytes.
