[Classification of asymptomatic autoimmune thyroiditis by thyrotropin-releasing hormone loading].

Thyrotropin-releasing hormone loading was performed on 91 patients with asymptomatic autoimmune thyroiditis. Four women had no response to this loading test and had high levels in serum total and free thyroxine (TT4, FT4) and in serum total and free triiodothyronine (TT3, FT3). These patients might be classified as subclinical hyperthyroidism (Group G). Twenty-four patients had normal levels of both basal and peak thyrotropin after loading and were classified as Group I. There were no significant differences between 45 controls (Group C) and Group I patients in serum thyroid hormone levels. Patients with normal basal and high peak levels of thyrotropin were included in Group II. The number of patients in this group was 53. The mean levels of basal and peak thyrotropin were 4.8 microU/ml and 39.6 microU/ml, respectively, and were significantly higher than in Group C and Group I (P less than 0.005). In 10 patients classified as Group III with high levels of both basal and peak thyrotropin, serum concentrations of TT4, FT4 and FT3 were significantly lower than in the other groups (P less than 0.025); however, significant differences in TT3 could not be seen among them. Serum cholesterol levels gradually increased from Group C to Group III. There were significant differences between Group C and Group II (P less than 0.05).

Islet cell antibodies in the Japanese population and subjects with type 1 (insulin-dependent) diabetes.

Islet cell antibodies were studied in 1,112 non-diabetic adults, 473 normal school children and 162 Type 1 (insulin-dependent) diabetic patients in a Japanese population. The prevalence of islet cell antibodies was 0.5%, 0.4% and 32%, respectively. Most islet cell antibodies positive subjects with Type 1 diabetes had short duration of the disease. No patients who had over 10 years from the onset had islet cell antibodies. Six non-diabetic adults with islet cell antibodies were followed for 4 years. Only one with Hashimoto's thyroiditis showed a diabetic pattern in her oral glucose tolerance test. However, none developed overt insulin-dependent diabetes until 1984. Two out of these six subjects continued to be positive for both islet cell antibodies and antithyroid antibodies or antinuclear antibodies. Islet cell antibodies in the remaining four patients disappeared during the second year. It is difficult to predict the onset of Type 1 diabetes by islet cell antibodies in non-diabetic individuals because they may be transient.

Antinuclear antibodies in childhood diabetics.

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.

A population survey of pancreatic islet cell antibodies and antithyroid antibodies.

In a survey of one Japanese population, we detected pancreatic islet cell antibodies (ICA), antithyroid antibodies (ATA) and antinuclear antibodies (ANA). The prevalence of ICA was 6 out of 1125 cases, or 0.5%. ATA and ANA were detected in 8.9% and 1%, respectively. There were no cases of either type I or type II diabetes in subjects with ICA. But there was one case who had ATA and another with ANA. Serum samples from this population had been obtained once a year from 1979 and one case with neither ATA nor ANA was found positive for ICA in 1980. Identical tests for ICA were performed on 80 childhood diabetics as were carried out on type I diabetics. Pancreatic isles cell surface antibodies (ICsA), ATA and ANA were studied simultaneously. The prevalence of ICA in 80 cases was 36.3% and that of ICsA was 13.8%. 4 cases had both ICA and ICsA. The prevalence of ATA was 11.2% and that of ANA was 16.3%.
