Anorexia nervosa is a syndrome of unknown etiology. It is associated with multiple endocrine abnormalities. Hypothalamic monoamines (especially serotonin), neuropeptides (especially neuropeptide Y and cholecystokinin) and leptin are involved in the regulation of human appetite, and in several ways they are changed in anorexia nervosa. However, it remains to(More)
The marked endocrine changes that occur in anorexia nervosa have aroused a great deal of interest, and over the last decade much research has been conducted in this field. The endocrine disturbances are not specific to this disorder, as they also occur in starvation states secondary to other causes, and they return to normal upon weight restoration.(More)
OBJECTIVE To investigate whether elevated ACTH-stimulated 17-hydroxyprogesterone (17OHP) levels are caused by CYP21 genetic defects or by a general adrenal hyperresponsiveness in hirsute patients. METHODS A total of 337 hirsute patients were evaluated by Ferriman-Gallwey score, serum testosterone, ACTH-stimulated 17OHP, and cortisol during the follicular(More)
The inhibitory action of physiological to pathophysiological serum cortisol levels on TSH secretion were investigated in 12 patients with Addison's disease on 3 occasions. 1) In continuation of the conventional hydrocortisone (HC) substitution, a medium dose of HC (0.5 mg/kg) was infused over 23 h. 2) After 24-h withdrawal of HC, the patients had placebo(More)
BACKGROUND AND PURPOSE In patients with hypertension, medication adherence is often suboptimal, thereby increasing the risk of ischemic heart disease and stroke. In a randomized trial, we investigated the effectiveness of a multifaceted pharmacist intervention in a hospital setting to improve medication adherence in hypertensive patients. Motivational(More)
OBJECTIVE To perform an audit on the examination of hirsute patients and to establish a rational routine examination program in an outpatient endocrine clinic. DESIGN Systematic, retrospective audit. SETTING Academic tertiary-care medical center. PATIENT(S) Three hundred forty women with hirsutism as the referral diagnosis. INTERVENTION(S) Hormone(More)
An enzyme antigen immunoassay for a specific determination of serum cholinesterase is described. Polyclonal and monoclonal antibodies against cholinesterase have been used. Hydrophobic binding of the specific antibody to a microtitre plate was followed by incubation with the samples, and the activity of the bound cholinesterase was assayed by the Ellman(More)
Anorexia nervosa (AN) is associated with multiple endocrine alterations. In the majority of AN patients, basal and GHRH-stimulated serum GH levels are increased. The metabolic effects of GH are known to be related to its pulsatile secretory pattern. The present study was performed to examine GH pulsatility in AN using the techniques of deconvolution(More)
This study assessed the controversial role of endogenous opioids and cortisol in the regulation of TSH and PRL secretion in humans. Seven euthyroid male patients with Addison's disease were studied four times, with an interval of 1-3 months, as follows: 1) during normocortisolism [graduated infusion of hydrocortisone, 0.4 mg/kg, over 19.5 h]; 2)(More)
Patients with anorexia nervosa (AN) are GH resistant, with elevated GH levels and low serum levels of total insulin-like growth factor I (IGF-I). IGF-I action is modulated by IGF-binding proteins (IGFBPs), and a variety of catabolic states has been characterized by the presence of increased IGFBP-3 proteolysis. The present study was performed to examine the(More)
