The impact of obesity on hormonal parameters in hirsute and nonhirsute women.

The influence of obesity on sex hormone-binding globulin (SHBG) and androgen concentrations in hirsute and nonhirsute women has been evaluated. The study was performed in 226 hirsute women (88 obese and 138 non-obese) classified as being affected by polycystic ovarian syndrome (PCOS) or by idiopathic hirsutism (IH) and in 100 nonhirsute control women ([C] 60 lean and 40 obese). SHBG, free testosterone (fT), androstenedione (A), estradiol (E2), dehydroepiandrosterone sulfate (DHEAS), and gonadotropin levels were measured during the first week of the menstrual cycle by radioimmunoassay (RIA).

Increased 17 alpha-hydroxyprogesterone response to ACTH in silent adrenal adenoma: cause or effect?

Objective: Recent studies suggest a possible connection between silent adrenal nodules and mild forms of 21-hydroxylase deficiency. It remains unclear whether the enzymatic deficiency is generalized or intrinsic to the adrenal mass. To help to clarify this, we have studied 17 alpha-OH-progesterone (17OH-P) response to ACTH stimulation in a group of patients with adrenal 'incidentaloma' in comparison with normal subjects.

Endocrine evaluation in patients treated with interferon-alpha for chronic hepatitis C.

The aim of our study was to evaluate the hormonal profile in a group of 31 subjects who underwent recombinant interferon-alpha therapy for chronic active hepatitis C. Hormonal determinations were performed before treatment began and at the end of the 3rd and 6th months of therapy. Free-T4 concentrations, though remaining in the normal range, showed a significant reduction (p < 0.

The use of flutamide in the management of hirsutism.

The aim of our study was to evaluate the clinical efficacy of flutamide (Flu), when used alone, on the course of hirsutism and to assess its effect on hormonal secretion. Thirty-six hirsute women [11 patients were affected by polycystic ovarian syndrome (PCOs), and 25 were classified as having idiopathic hirsutism (IH)] were treated with Flu, 375 mg daily for a 4-month period. We found a marked clinical improvement in the degree of hirsutism in all patients.
