Antinuclear Antibodies in Childhood Diabetics

抄録

Antinuclear antibodies (ANA) were detected both in type 1 diabetic children and in control subjects. The incidence of ANA in eighty of these diabetics was 16.3%, as determined using two different substrates, human pancreas and human peripheral leucocytes. The incidence and the patterns in the detection of ANA were the same.
Four hundred and seventy-three children and one thousand one hundred and twenty-five adults served as the controls. The incidence of ANA in non-diabetic children was 0.8% and that in one adult population was 1.1%. Therefore, the incidence of ANA in childhood diabetics was significantly higher.
We studied autoantibodies in childhood diabetics, in normal children and in one adult population. Pancreatic islet cell antibodies (ICA) were detected in 29 out of 80 type 1 diabetics (36.3%) in two out of 473 normal children (0.4%) and in six cases in one population (0.5%). Thyroid microsomal antibodies (MCHA) were detected in 9 out of 80 childhood diabetics and the incidence of MCHA in type 1 diabetics was significantly higher than in the controls.
