Radiotherapy of brain tumours given to children and adults is connected with various hormonal dysfunctions later in the life. There are anterior pituitary hormones deficiencies, hyperprolactinemia and precocious puberty. Their severity and frequency depends on the dose applied, age of the radiotherapy and time after radiotherapy. In children, the most important is early recognition of them, with growth hormone deficiency as most common. The impact of cranial irradiation on gon...

It has been reported that orexins play an important role in the regulation of GH secretion. It is suggested that the defect in orexins synthesis could be responsible for the disturbances in GH synthesis and consequently aggravate metabolic disturbances. The aim of the study was to assess plasma orexin A levels in patients with acromegaly in relation to the activity of disease and hormonal and metabolic profiles. Fifty-five patients with acromegaly divided into three groups acc...

Acromegaly is associated with various skeletal deformities and in some cases with bone deterioration. The aim of the study was to assess the skeletal status using quantitative ultrasound (QUS) in patients suffering from acromegaly. A group of 38 patients with acromegaly (27 women and 11 men) in mean age of 57.21±9.85 y in various gonadal status was compared with a control group matched for sex, age and body mass. QUS measurements at hand phalanges were performed with DBM ...

Acromegaly causes various cardiovascular dysfunctions, and cardiovascular complications are the main cause of increased mortality in non-cured acromegalic patients. The aim of the study was assessment of flow mediated dilatation (FMD) and the concentration of soluble vascular cell adhesive molecule (sVCAM) as the selected markers of endothelial dysfunction in patients suffering from acromegaly. The study was carried out in 40 patients with acromegaly in various stages of the d...

Introduction: Peroxisome proliferatior-activated receptor-γ2 (PPAR-γ2) plays a crucial role in adipogenesis and has been shown to be involved in the control of immunoregulation and inflammation. Orbital fibroblast differentiation to adipocytes is a PPAR-γ dependent process essential for pathogenic tissue remodeling in Graves’ orbitopathy (GO). Genetic variation in PPAR-γ2 gene may modulate expression and/or function of molecule encoded by this gene.</p...

Introduction: Both genetic and environmental factors contribute to clinical manifestation of Graves’ disease including the response to medical therapy. CTLA-4 gene is an important inhibitor of T-cell activation and its polymorphisms may influence the course of the disease.Goal: We investigated the association between CTLA−4 gene polymorphisms: c.49A>G, g.319C>T, g.*642AT(8_33), CT60, and Jo31 and the response to ph...
