Changes in the level of antidiuretic hormone (ADH), adrenocorticotropic hormone (ACTH), somatotropic hormone (STH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), prolactin (PL), thyroxin (T4), triiodothyronine (T3) and thyroxine-binding globulin (TBG) have been assessed before and during multiorgan excision in 22 donors with brain death. A progressing decrease in ADH blood supply and changes in ACTH, STH, FSH and PL content have been recorded. No regularities have been observed in LH level changes. TSH and thyroid hormone changes were in most cases characterized by a gradual decrease in their plasma levels. A drop in T3 concentration observed at the initial stage of the study was most pronounced with practically normal T4 and TBG values, that also decreased by the moment of heart excision. It has been concluded that brain death is accompanied by a considerable neuroendocrine disfunction and a marked syndrome of low T3 content.

Breast cyst fluid (BCF) and plasma levels of beta-endorphin (beta-EP), oestradiol (E2), progesterone (P), luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), prolactin (PRL) and cortisol were assayed radiochemically in a group of 10 premenopausal women aged 45-50 years suffering from gross cystic breast disease. The concentration of beta-EP (fmol/ml) in BCF (17.6 +/- 4.6 S.E.) was over four times higher than that in plasma (4.2 +/- 0.5 S.E.). The level of E2 was 41 times higher (1738.2 +/- 350.5 S.E. pg/ml) and that of P was 47 times higher (65.47 +/- 8.25 S.E. ng/ml) in BCF than in plasma. The significantly increased values of beta-EP, E2 and P in BCF and the identification of beta-EP in the cyst-lining epithelium indicated that local synthesis occurs. Growth factor-like properties of beta-EP and E2 are responsible for the propagation of cystic changes. The autonomous formation and activity of beta-EP, E2 and P in cystic formations were not correlated with LH, FSH, TSH and cortisol levels, which were significantly higher in plasma than in BCF. The concentration of PRL in BCF was not significantly higher than that in plasma. Moreover, the plasma concentrations of testosterone, androstenedione, thyroxine, triiodothyronine, thyroxine-binding globulin and sex-hormone-binding globulin were within the normal ranges. In this study we demonstrated synergism between beta-EP and steroid hormones which encourages the development of gross cystic disease in premenopausal women.

To assess whether neuroendocrine dysfunction is present in children with acquired immunodeficiency syndrome (AIDS) and growth failure, we evaluated the thyroid, adrenal, and growth hormone-insulin-like growth factor I (IGF-1) axes in nine children with AIDS and failure to thrive. Basal thyroid-stimulating hormone, free thyroxine, and triiodothyronine levels were normal in eight of the nine children and indicated primary hypothyroidism in one child; thyroxine levels were elevated in four and normal in five children. Thyroxine-binding globulin levels were elevated in all children. Serial measurements of thyroid-stimulating hormone, made hourly from 2 to 6 pm and from 10 pm to 2 am, revealed a flat diurnal rhythm of thyroid-stimulating hormone in six children, which may indicate early central hypothyroidism, and a normal nocturnal rise in the remaining three children. Basal plasma corticotropin and aldosterone levels were normal in all children, plasma renin levels were normal in three and elevated in six children, and cortisol levels were normal or elevated in all children. Corticotropin-stimulated cortisol levels exceeded 500 nmol/L (18 micrograms/dl) in all children except one, who was receiving treatment with ketoconazole. Thus adrenocortical function appeared to be grossly intact. The peak growth hormone responses to provocative testing was normal (greater than 7 ng/ml) in eight children and low in one child. The plasma level of insulin-like growth factor I was normal in eight of the nine children and low in one child. We conclude that growth failure in children with AIDS does not usually result from a recognized endocrine cause and that adrenal function is usually normal. However, endocrine deficiency may contribute to morbidity in some children with AIDS.

Potential therapeutic effects of combined oral contraceptives (COC) rigevidon and ovidon (estrogen:gestagen ratio of 1:5) were studied in 97 women aged 19-35 years. With respect to the anatomical state of the thyroid, the patients were divided into two groups: group 1 included 42 women with normal thyroid function and group 2 included 55 women with euthyroid hyperplasia of the thyroid gland of stage I-II (the anatomical state of the thyroid gland was ranked according to the five-point Swiss scale adopted by WHO in 1975). All patients had a history of pregnancy, normal delivery, or abortion. The state of the pituitary-thyroid system was estimated by absorption of iodine isotopes in the thyroid tissue, and by the blood levels of thyrotropic hormone, thyroxine-binding globulin, thyroxine, and triiodothyronine. Activity of the pituitary- adrenal system was estimated by the blood levels of adrenocorticotropic hormone (ACTH) and cortisol. Blood samples were withdrawn 9 and 10 hours prior to the onset of COC administration, and after 24 and 48 weeks of COC use. The changes in the functional state of the pituitary- thyroid system in groups 1 and 2 were identical throughout the entire period of COC administration. Progressive increase in the levels of thyroxine and triiodothyronine was associated with inhibition of the thyrotropic function of the pituitary seen as decrease in thyrotropin levels. COC administration caused decrease in size of hyperplastic tyroid gland. Prior to COC administration, women in group 2 showed significant elevation of ACTH levels and marked decrease in ACTH levels and increase in cortisol levels in both groups. Normalization of the size of thyroid gland indicated that COC be used therapeutically in patients with thyroid hyperplasia.

We studied the hormonal millieu and possibility of altered thyroid function in 25 patients in a surgical intensive care unit (ICU) who had severe life-threatening illnesses. Sixteen patients had septic complications and nine patients had multiple-system injuries. On admission to the ICU, serial measurements were begun of thyroxine (T4), triiodothyronine (T3), T4-binding globulin, thyrotropin (thyroid-stimulating hormone [TSH]), corticotropin (adrenocorticotropic hormone [ACTH]), cortisol, prolactin, human growth hormone, catecholamine, insulin and glucose, lactate, retinol-binding protein, prealbumin, and transferrin levels. All patients initially had low normal levels of T4 (4.5 +/- 2 micrograms/dL) and T3 (55 +/- 26 ng/dL), with normal TSH levels (2.3 +/- 2.3 microU/mL) (the "low T3 syndrome"). The 11 surviving patients had their levels increase to normal before leaving the ICU (T4, 7.0 +/- 2.1 micrograms/dL; T3, 110 +/- 48 ng/dL; and TSH, no change). The 14 patients who died showed further decreases before death (T4, 2.6 +/- 2.1 micrograms/dL; T3, 30.6 +/- 23.5 ng/dL; and TSH, 0.9 +/- 0.7 microU/mL). The corticotropin, cortisol, prolactin, and growth hormone levels were normal throughout the study. Catecholamine levels were high initially and decreased in surviving patients. Epinephrine levels increased greatly in nonsurvivors before death, and the norepinephrine-epinephrine ratio decreased from 5.7:1 to 2:1. After protirelin (thyroid-releasing hormone [TRH]) stimulation, the TSH level increased either minimally or not at all in six patients who eventually died. This indicates hypothalamic-pituitary dysregulation or suppression, and altered release and/or peripheral metabolism of T4. Whether this represents a deficiency of thyroid hormone for cell and organ function remains to be established.
