Hypogonadotropic hypogonadism is a syndrome which may be manifested clinically by low sex steroids because of low (or inappropriately normal) gonadotropins. To date, more than 30 genes were reported as possible reason for this condition, but genetic basis is still unknown for ~60% of HH cases. Due to this fact we decided to analyze mRNA expression of several HH-related genes which can be found in leukocytes of peripheral blood: GNRHR and GNRH1 (which are necessary for adequate...

Background: Diabetes mellitus is one of the serious acromegaly complication.As well known, glycemia influences growth hormone (GH) secretion. From this point of view, it is interesting to investigate feature peculiarity of GH and Insulin like Growth Factor 1 (IFG-1) secretion when acromegaly is coupled with diabetes mellitus.Aim: Of this study was to investigate diabetes mellitus influence on GH and IGF-1 levels in acromegalic pati...

Introduction: Pituitary apoplexy is the rare case of panhypopituitarism. We are presenting a clinical case of pituitary apoplexy in a previously healthy 37-year-old woman.Case report: A 37-year-old woman developed amenorrhea in August 2011. She did not visit a doctor in that time. In December 2011 she suddenly felt severe headache, symptoms of polyuria and polydipsia and temperature of 39 °C. Laboratory results revealed an increased erythrocyte sedi...

Introduction: Resistance to thyroid hormone (RTH) is a rare disorder characterized by reduced tissues’s responsiveness to thyroid hormones (TH). Usually patients with RTH have not clinical signs except goiter. We describe a 70-years old woman with RTH and autoimmune thyroiditis simultaneously.Case report: Woman 70-years old was hospitalized in our department on August 2011 with suspicious of Thyrotropinoma because of high levels of TSH and fT4<...

Aim: To pay attention to the so rare symptom of diffuse toxic goiter (DTG) as fever.Materials and methods: We report about 5 patients (all females, aged 18–38, mean – 31). Before, all patients were examined for fever of unknown origin of long duration. After the others reasons of the febrile body temperature were excluded, DTG was diagnosed. DTG was confirmed by the results of the clinical, hormonal and immunological investigations (T- and B-ce...

In 24 years old woman in March 2007 was diagnosed acromegaly (somatoprolactinoma) an active phase, hyperprolactinemia. Manifestations: rugged features, amenorrhea, galactorrhea, fasting GH – 144 ng/ml (N<10 ng/ml), IGF-1 – 586 ng/ml (N 48–450 ng/ml), PRL – 6726 mU/l (N 40–530 mU/l). According to pituitary MRT a tumor volume was 14.4 cm3, with supra- and infrasella growth. She was operated in May 2007: transnal transs...

Introduction: Previous studies demonstrated a relationship between T1- and T2-weighted signal intensity and tumor growth pattern in pituitary somatotropinomas. The goal of this retrospective study was to analyze the MRI characteristics of pituitary macroadenomas with different hormonal activity in newly diagnosed patients.Material and methods: Pre-treatment T1- and T2-weighted MR-images (Intera Achieva, PHILIPS, 3.0T) of patients with 42 non-functional a...

Background: Menstrual abnormalities (MA) can be the first sign of the disease.Aim: To assess the structure of MA before and after treatment of CD.Material and methods: Twenty-eight women with CD 39 (31.8;43.5) y.o., were investigated initially and 3.5 (2;5.5) years after treatment. Patients were subdivided into three groups: with normal cycles (NC; 26–30 days), oligomenorrhea (31–120 days), amenorrhea (>120 days)....

Prevalence of macroprolactin in serum (>40%) can be a cause of asymptomatic hyperprolactinemia. However, there is still lack of evidence how to manage with symptomatic patients with macroprolactinemia.We analyzed clinical data and monomeric prolactin levels in 85 women of reproductive age with hyperprolactinemia: NonTumor hyperprolactinemia (NT, n=31), MIcroadenomas (MI, n=32), MAcroadenomas (MA, n=22). Prolactin levels 171...

Our Pituitary Tumour Registry includes data about 346 patients with pituitary macroadenomas: 142 non-functional adenomas (NFA) including 18 (12.7%) giant, 62 macroprolactinomas – 6 (9.7%) giant, 141 somatotropinomas – 6 (4.3%) giant. We analysed clinical features of these 30 giant pituitary tumors (<40 mm at least one of the sizes): 18 NFA (11 Females; 7 Males), 6 prolactinomas (3 Females; 3 Males), 6 somatotropinomas (3 Females; 3 Males). Patients with giant NFA...
