IntroductionTwenty-four years after implementing the national salt iodization programme in Poland in 1997, the country is considered as adequate iodine supply. However, most reports do not take into consideration pregnant or lactating females. Additional intake of 150–200 µg KI per day, independently on levothyroxine (LT4) treatment, is a recommended dose for pregnancy and lactation due to Polish endocrinological guidelines. The study aim was t...

ITT is the test of reference for the diagnosis of adult GH deficiency (GHD), but also GHRH in combination with arginine (ARG) or GH secretagogues (GHS) are considered equally reliable tests. Testing with GHS alone is, anyway, a potent stimulus exploring the integrity of hypothalamic pathways controlling somatotropic function.We therefore aimed to clarify the diagnostic reliability of testing with ghrelin, the natural GHS.We studied...

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease caused by Hantavirus. One of the rare complications of this disease is hypopituitarism (only sporadically reported) due to hemorrhage, necrosis and atrophy of anterior pituitary lobe. The aim of the study was to investigate the anterior pituitary function in patients who recovered from HFRS.We evaluated 31 patients (29 male and 2 female), aged 38.7±2.2 years, with BMI 25.7±0...

Background: Pregnancy is a state of a higher iodine intake demand. Proper iodine status is important during pregnancy for fetal neurodevelopment and maternal thyroid function. Urinary iodine concentration (UIC) is the most common indicator of iodine status.Objectives: The aim of this study was to develop and validate a novel ion-pair HPLC-UV method to measure iodine in urine and to assess iodine status in pregnant women.Methods: Sa...

Introduction: Tumor necrosis factor alpha (TNF-α) and Interleukin-6 (IL-6) are potent immunomodulators and proinflammatory cytokines displaying varied functions. Apart from monocytes/macrophages, they are also produced by the cells in female reproductive tract. Polycystic ovarian syndrome (PCOS) is one of the commonest endocrine disorder amongst women of reproductive age group. Several polymorphisms in the promoter region of the gene TNF-α, IL-6 and Leptin receptors ...

Introduction: The human GNAS gene is coding for the alpha stimulatory subunit of the guanine nucleotide-binding protein. This G protein stimulates the activity of the adenylate cyclase enzyme which is in control of the production of various hormones in endocrine glands and also regulates bone development. Mutations in GNAS can lead to McCune Albright syndrome, progressive osseous heteroplasia or pseudohypoparathyroidism.Aim: Our aim was to find the genet...

Background: Gonadotropin-releasing hormone (GnRH) receptor is a G protein-coupled receptor involved in the synthesis and release of pituitary gonadotropins. GnRH analogs constitute the most widely employed medical treatment for prostatic cancer. The predominant mechanism of action is presumed to be via the inhibition of gonadotropins and resultant decrease in androgen. Although pituitary and extra-pituitary GnRH-R transcripts appear identical, their functional characteristics ...

Objective(S): Single nucleotide polymorphism (SNP) in endothelial nitric oxide synthase (eNOS) G894T may affect the oxidative stress response. Our objective was to examine G894T SNP eNOS genotype frequencies and its potential role with sperm motility in infertile men. Through this prospective controlled study in the Andrology Unit, we have enrolled infertile (n=70) and healthy (n=60) men. Sperm motion kinetics assessed by computer assisted semen analysis (CASA), ...

Introduction: Treatment with dopamine agonists in patients with prolactinomas and Parkinson’s disease is associated with central side effects. Central side effects may depend on a substance’s ability to pass the blood-brain barrier which can be actively controlled by transporter molecules such as the P-glycoprotein encoded by the ABCB1 gene.Aim of the study: To determine whether cabergoline is transported by the P-glycoprotein and whether polym...

Case report: 24-year. old man presented with change in facial appearance and joint pain. His symptoms began at puberty with the thickening and folding of the skin on the forehead and scalp and thickening of his fingers. These changes progressed over the next 5 years with marked seborrhoea, hyperhidrosis and linear palmar–plantar keratosis. The lower legs and forearms are cylindrically thickened, hands and feet increased in size, the terminal phalanges of the fingers show ...
