Introduction: Acne vulgaris is a common skin disorder among both adolescents and adults. Its multifactorial pathogenesis may include insulin resistance, especially in cases resistant to classical treatment methods. There are few studies which have already proved acne vulgaris development in the course of insulin resistance, however, there are more studies necessary in order to include insulin resistance evaluation in classical acne vulgaris diagnosing and treatment.<p clas...

Objective: The association between thyroid function and mood disorders has long been recognized but little is known about the mechanisms underlying this relationship. Thyroid dysfunction often leads to the development of mental diseases and in patients with affective disorders, 1–4% suffers from hypothyroidism and 4–40% show signs of subclinical hypothyroidism. The aim of the present study was to assess the effects of hypothyroidism on metabolic processes in the brai...

Background: Chemerin (CHEM) is a newly-discovered adipokine involved in the immune, metabolic and reproductive processes. Low-grade state inflammation (LGSI) is a key element in the pathogenesis of metabolic syndrome (MS).Objectives: The aim of the study was to assess the effect of age on MS prevalence, androgenic status as well as on selected inflammatory indices and CHEM plasma concentrations. Additionally we investigated correlations between CHEM and ...

The diagnosis of subclinical hypercortisolemia in patients with incidental adrenal tumors remains a challenge, as there are no unambiguous criteria for diagnosis. The discovery of a substance whose secretion increases under the influence of cortisol would make it easier to make therapeutic decisions. Hypercortisolism causes a change in the distribution of adipose tissue, so it can be assumed that it also affects secretion of proteins secreted by adipocytes (adipokines). The ai...

Background: The treatment of choice in prolactinomas are dopamine agonists, with surgery reserved for cases refractory to or poorly tolerant of pharmacotherapy. Little is known on the associations between clinical, neuroradiological and pathological features influencing the efficacy of transphenoidal surgery.The Aim: To evaluate clinical, neuroradiological and neuropathological aspects of surgically treated prolactinomas in women, with a particular empha...

Hypersensitivity of hypothalamic–pituitary–adrenal (HPA) axis is considered to be an important factor in the pathogenesis of depression. Interestingly, glucagon-like peptide-1 (GLP-1) – an incretin hormone involved in the maintenance of glucose homeostasis in the periphery is known to activate HPA axis. The aim of the present study was to investigate whether prenatal stress (an animal model of depression) may influence levels of GLP-1 and GLP-1 receptor (GLP-1R)...

Background: Copeptin (pre-proAVP) secreted in equimolar amounts with vasopressin (AVP) closely reflects AVP release. Previously it was shown that copeptin is stimulated in standard pituitary function tests acting through hypothalamic centres. Furthermore, copeptin has been shown to subtly mirror stress potentially mediated via CRH. To further test a potential direct interaction of CRH with copeptin release which could augment AVP effects on pituitary function, we investigated ...

: The observed increase in the incidence of Hashimoto’s thyroiditis (HT) requires research on factors that may affect its development. One of them may be vitamin D deficiency which is an epidemiological problem all over the world.Aim: The assessment of influence vitamin D deficiency on the HT activity.Material and methods: 310 people were enrolled in the study: 155 patients with HT (a-TPO and/or a-TG positivity)-144 women (93%...

Central obesity and increased visceral adipose tissue (VAT) are key factors contributing to metabolic dysfunction in PCOS. We therefore hypothesized that there would be alterations in the morphology and function of adipocytes from visceral fat depots. The female offspring of pregnant sheep treated biweekly with either 100 mg of testosterone propionate (TP) or vehicle control (C) from day 62–102 of gestation develop a clinically realistic PCOS-like condition. They develop ...

Introduction: The aim of the study was to asses frequency of the components of metabolic syndrome (MS) according to the criteria of the International Diabetes Federation (IDF) in patients with adrenal incidentaloma (AI) without hormonal activity.Design: The study comprised of patients with AI without hormonal activity, confirmed in CT. The adrenal function was determined by measuring circadian rhythm of cortisol and/or dexametasone suppression test, aldo...
