The Pituitary-Thyroid Axis in Acromegaly
The pituitary-Thyroid axis of 12 Acromegalic patients was evaluated by measurement of the concentration (Total and free of thyroxine T4, T3 and revers T3 (rT3) and TSH, GH and prolactin before and after in stimulation with TRH. Using an ultrasensitive method of TSH measurement (IRMA) basal serum TSH levels of patients (0.76, 0.07-l.90mlU/L) were found slightly but significantly (P < 0.01), low...

INTRODUCTION Substantial controversy exists regarding the association between testosterone serum levels and prostate cancer. OBJECTIVE To evaluate the levels of hypothalamic-pituitary-testicular axis hormones in the sera of men with prostate cancer and atypical small acinar proliferation as well as those with normal biopsies.

متن کاملRecovery pattern of hypothalamo-pituitary-testicular axis in patients with macroprolactinomas after treatment with cabergoline
BACKGROUND & OBJECTIVES Hyperprolactinaemia affects testicular functions by influencing hypothalamo-pituitary-testicular (HPT) axis at various levels. Available literature on the level of defect, time course of improvement of gonadal functions and its relation with decline in prolactin levels is scanty. We carried out this study to evaluate the HPT axis in patients with macroprolactinomas, befo...
متن کاملFamilial Longevity Is Not Associated with Major Differences in the Hypothalamic–Pituitary–Gonadal Axis in Healthy Middle-Aged Men
CONTEXT A trade-off between fertility and longevity possibly exists. The association of the male hypothalamic-pituitary-gonadal (HPG) axis with familial longevity has not yet been investigated. OBJECTIVE To study 24-h hormone concentration profiles of the HPG axis in men enriched for familial longevity and controls. DESIGN We frequently sampled blood over 24 h in 10 healthy middle-aged male...
متن کاملEndocrinopathy in thalassaemia major.
Pituitary, adrenal, and pancreatic functions were investigated in 9 patients with thalassaemia major. 9 a.m. plasma ACTH values were 148-480 pg/ml (normal range 15-70 pg/ml). Cortisol and growth hormone response to insulin-induced hypoglycaemia was normal in all. 24-hour urinary excretions of 17-ketosteroids and 17-hydroxycorticosteroids were normal. There was normal cortisol response to intram...
