Growth hormone deficiency (GHD) impairs bone mass and strength. Androgen deficient men exhibit impaired bone mass, but the extent to which testosterone replacement can prevent this remains disputable. The aim of this study was to assess whether androgen deficiency presents an additional risk factor for bone health in male patients with GHD and whether this is correctable by testosterone substitution.A group of 81 male patients with GHD, not receiving GH ...

Previous studies have shown exaggerated ACTH and cortisol responses to ghrelin. Seven patients who were cured by transsphenoidal operation from CD were included in the study and tested with ghrelin (1 mcg/kg i.v.) before and six months after the operation. Their results were compared with eight healthy control subjects. Results are presented as mean±S.D. Mann–Whitney and Wilcoxon signed rank test were used for statistical analysis.<p class="abstext...

Polycystic ovary syndrome (PCOS) is associated with adiposity and metabolic changes predisposing to insulin resistance. Because the recently discovered GH secretagogue, ghrelin is intimately involved in the control of appetite and weight regulation, we investigate ghrelin levels in non-obese and obese PCOS patients. Ten obese (BMI=32.50±1.57 kg/m2) and ten non-obese (BMI=20.45±0.51 kg/m2) patients with PCOS and their respective controls were eva...

Background/objectives: The aim of the study was to assess association between diabetes mellitus (DM) and arterial hypertension (AH) in patients with adrenal incidentaloma.Design and methods: One hundred and eleven consecutive patients with incidentally discovered adrenal tumours were included in the study. OGTT was done and 24 h urinary catecholamines were measured. Aldosterone and plasma renine activity (PRA) were determined, and 1 mg dexametasone test ...

Obesity protects from osteoporosis. Bone remodeling and energy metabolism could be regulated by the adipocyte-derived hormone, leptin acting on osteoblasts though hypothalamic pathways. Hypothalamic lesions cause obesity. Since most of these patients are also hypopituitary with low IGF1 which could affect bone metabolism the aim of our study was to investigate whether obesity would protect them from osteoporosis.Three groups of patients were studied: (1)...

Anorexia nervosa (AN) is associated with bone loss due to weight loss, decreased caloric intake, amenorrhoea and behavioral changes. The most important predictor of the occurrence of bone loss is body weight (BMI <16.5 kg/m2). Previous studies suggested that many factors including effects of chronic undernutrition in AN patients is associated with a reduction of bone formation (osteocalcin-OC) uncoupled with increased resorption markers (crosslaps-CTx). The aim ...

It was previously shown that patients with primary hyperparathyroidism (PHPT) are insulin resistant. The aim of our study was to evaluate the effect of surgical treatment on insulin sensitivity and lipid levels in patients with PHPT. In 21 patients with PHPT (age: 56.24±8.69 years, BMI 25.2±3.81 kg/m2) lipid levels (TC, HDL, LDL, TG, Lp(a)) and insulin sensitivity were determinated before and 4 months after surgical treatment. Insulin sensitivity was evalu...

Somatuline Autogel® 120 mg (SATG, Ipsen, Sweeden) is a high dose sustained release aqueous gel formulation, supplied in a prefiled syringe and given by deep subcutaneous injection. The aim of this cross-sectional hospital based study, approved by the local ethical committee, was to investigate efficacy and tolerability of SATG given every 4 weeks in patients with active acromegaly.Twenty patients (9f, 11m) aged 42.9±17.8 (range 17&#1...

Patients with hypopitutarism have higher cardiovascular morbidity and mortality rates than general population, as manifested by elevated fasting lipids and insulin resistance. The aim of our study was to evaluate the lipid levels and insulin responses during oral glucose tolerance test (OGTT) in adult onset growth hormone deficiency (AO-GHD), without growth hormone replacement during a follow-up period of seven years. Ten hypopituitary patients with operated non-functioning pi...

Background: Polycystic ovary syndrome (PCOS) is a common endocrine-metabolic disease that occurs in about 10% of women in reproductive age. Today, PCOS is considered not only reproductive edocrinopathy but also a metabolic disorder associated with long-term health risks, including diabetes mellitus and cardiovascular disease.Objectives: The aim of this study was to evaluate the presense of early vascular demage in normal-weight women with polycystic ovar...
