[Anterior pituitary function before and after treatment in twenty-three patients with isolated adrenocorticotropic hormone (ACTH) deficiency reported in Japan (author's transl)].

Anterior pituitary function in 23 patients (16 men and 7 women, aged 27 to 68) with isolated ACTH deficiency was analyzed. Four were our own cases while the other 19 cases were ascertained by questionnaire. Both the baseline TSH levels and the peak TSH responses to TRH were high before treatment in more than half the cases but were normalized after treatment. This abnormality was found in patients younger than 50. The peak prolactin responses to TRH were excessive before and after treatment in three-fourths of the cases but decreased after treatment. The peak HGH responses to ITT were excessive in 3 patients before treatment an increased after treatment in 5 out of 6 cases. The peak LH and FSH responses to LH-RH were low or high in 20-30% of cases, but these abnormal responses were reduced to half after treatment. These results demonstrate that many disorders of the anterior pituitary function were found in patients with isolated ACTH deficiency but that these disorders became normal after treatment.

Inverse correlation between urinary 17-hydroxycorticosteroid (17-OHCS) excretion and thyrotropin-releasing hormone (TRH)-induced thyrotropin (TSH) response in disorders of adrenocorticotropic hormone (ACTH) and adrenal secretion.

A TRH test was performed in patients with Cushing's syndrome and isolated ACTH deficiency, and serum TSH was measured. A TRH-induced TSH showed low response in patients with Cushing's syndrome but showed excessive response in patients with isolated ACTH deficiency. However, in both diseases TRH-induced TSH response showed a tendency to normalize after the treatment. Urinary 17-OHCS excretion was measured in patients with Cushing's syndrome and isolated ACTH deficiency before and after the treatment. There was a definite inverse correlation between ;the logarithm for urinary 17-OHCS excretion and the peak TSH response to TRH. These results suggested that glucocorticoids regulate not only ACTH but also TSH secretion.

[The incidence of antithyroid antibodies in relatives of patients with thyroid disorders (author's transl)].

In order to elucidate a predisposition for so-called autoimmune thyroid disorders such as Graves' disease, chronic thyroiditis and myxedema, the incidence of thyroid antibodies was studied in relatives of patients with thyroid disorders. The relatives studied were all limited within a two degree relationship of the patients. Serum antibodies to thyroglobulin and thyroid microsome were determined by susing the method of a hemagglutination test. The following results were obtained; 1) Thirty six of 103 relatives (35%) were found to have such antibodies, and sixteen (7.0%) of 230 hospital controls were positive. This difference was significant (P less than 0.001). 2) There was no difference in the incidence among relatives of patients with Graves' disease and those chronic thyroiditis. 3) With regard to age, the incidence in the more than 20 years old group was significantly greater than that in the under 19 years old group. 4) There was no difference in the incidence between male and female. These results suggested that the relatives of patients with so-called autoimmune thyroid disorders may have a predisposition for thyroid disorders.

[Anterior pituitary function in patients with cerebrovascular disease: with special reference to growth hormone secretion in response to TRH administration (author's transl)].

HGH secretion in response to TRH was studied in patients with cerebrovascular disease in order to elucidate an influence of cerebrovascular lesions on the hypothalamus-anterior pituitary function. Blood specimens were obtained before and at the time of 10, 20, 30, 40, 60, 90 and 120 minutes after the intraveneous administration of 200 microgram of TRH in 17 patients with cerebral hemorrhage and in 8 patients with cerebral infarction. With regards to the natural fluctuations of serum HGH caused by cerebrovascular disease, the blood specimens were obrained at the time of 0, 30, 60, 90 and 120 minutes without the administration of TRH in 4 patients with cerebral hemorrhage and in 4 patients with cerebral infarction. Serum HGH was measured using the RIA method and the following results were obtained: 1) An increase in serum HGH was observed in 1 patient with cerebral hemorrhage out of 8 patients with cerebrovascular disease without TRH administration. 2) In 5 out of 17 patients with cerebral hemorrhage, an increase in serum HGH was observed following TRH administration. Three out of these 5 patients were included in the group of non-coma, and 4 out of the 5 patients were female. 3) In 2 out of 8 patients with cerebral infarction, an increase in serum HGH was observed following TRH administration.
