Primary hyperparathyroidism (PHPT) is often associated with reduced bone mineral density (BMD). An open-labeled, prospective trial was conducted to determine whether denosumab 60 mg subcutaneously given every 6 months, maintains or improves BMD in patients with PHPT.Six patients had symptomatic PHPT and met surgical guidelines however refused surgery, and twelve patients had mild PHPT, asymptomatic except low BMD. The primary outcome index, BMD, was meas...

Background: Neuroendocrine tumors awareness is developing. Carcinoid syndrome and hormonal overproduction may be controlled with somatostatin analogues in majority of cases. However, due to unspecific symptomatology in early stages of disease, majority of cases are diagnosed when process is disseminated. Co-morbidities and coexisting diseases are present in most of patients. Bone loss may be accelerated by metastizing tumor, peptides secreted or decreased absorption of vitamin...

In acromegaly, an excessive GH secretion by pituitary adenoma, minimal active disease may be defined as slow progression of characteristic signs and symptoms at presence of slightly elevated or normal IGF1 levels and lack of GH suppression after glucose load. Nadir post-glucose GH level defining active disease is under permanent discussion and depends on assessment methods. IGF1 reference range is wide, must be age-adjusted and often is sex-dependent. From mid-00’s excess...

Idiopathic hypogonadotropic hypogonadism (IHH) is caused by an isolated defect in GnRH release or action and classified as the Kallmann syndrome with associated anosmia or normosmic IHH in the presence of a normal sense of smell. Patients with IHH have absent or incomplete sexual maturation and infertility. Usually long term GnRH or gonadotropin therapy in these patients can induce spermatogenesis and puberty and is followed by testosterone therapy to maintain normal virilizat...

About 8–10% of erectile dysfunction (ED) is caused by hormonal causes, but in men over 65 years testosterone deficiency due to aging seems to play important role. In population of Polish men with relative poor health status, the prevalence of testosterone deficiency in elderly men with ED is probably higher. We evaluated the prevalence of low and low-normal testosterone levels in men with ED in population of Polish men over 65 years.Material and met...

Introduction: Impaired glucose tolerance and insulin resistance are frequently associated with acromegaly. The aim of this study was to assess the impact of long-acting somatostatin analog treatment on glucose homeostasis in acromegalic patients.Patients and methods: In this prospective study 16 naïve acromegalic patients (eight females, eight males; aged 51.5±10.9 years) were studied before and after 3-month therapy with long-acting somatostat...

Gynecomastia is a benign enlargement of the male breast due to the imbalance between androgens and estrogens in the breast tissue. In up to 40% of cases no evident reasons could be found. This idiopathic gynecomastia may be caused by excess aromatisation within breast tissue. Aromatase is a key enzyme in estrogen biosynthesis. Mutations and polymorphisms of aromatase gene could lead to its overexpression. Some endocrine disruptors - chemicals that interfere with hormone functi...

Introduction: Assessment of the efficacy of surgical treatment for Cushing’s disease (CD) is one of the biggest challenges in contemporary endocrinology. The aim of this study was prospective evaluation of factors influencing the result of transsphenoidal surgery for CD.Methods: The study population consisted of 36 consecutive patients with CD hospitalized in the Department of Endocrinology from 2005 to 2009 and operated on using the same surgical p...

Introduction: Real-time elastography (RTE) is a noninvasive ultrasound method of estimation of tissue stiffness by measuring the degree of local tissue displacements after a small compression. Recent data has shown indicate on its ability to differentiate benign and malignant tumors. The aim of the study was to evaluate the diagnostic accuracy of RTE in the diagnosis of malignant and benign thyroid nodules.Material and methods: A total of 75 thyroid nodu...

The aim of the study was to evaluate factors determining bone mineral density (BMD) and serum concentrations of osteocalcin (OC) and carboxyterminal telopeptide of type I collagen (ICTP) in acromegaly. Material consisted of 121 patients with active acromegaly, aged 23–80 years. In the whole group BMD, assessed by DXA, was: 0.35±0.15 at L2–L4, 0.60±0.11 at femoral neck, 0.05±0.12 at Ward’s triangle and 0.59±0.13 at trocha...
