Purpose: To reveal changes of the vegetative status, namely vegetative maintenance, vegetative reactance, and infringement of emotional status at patients with postoperative primary hypothyroidism (concerning central or total craws), the compensated treatment by levothyroxyn.Materials and methods: Sixteen persons are included in research with primary hypothyroidism with various etiology, compensated by levothyroxyn. The ages – 36–58 years, dura...

Background: Intratumoural hypoxia is associated with an aggressive and metastatic phenotype and poor prognosis. The transcription factor Hypoxia-inducible Factor-1α (HIF-1α) is a key regulator of hypoxia, inducing the expression of genes which promote tumour cell survival, such as carbonic-anhydrase IX (CA-IX) playing a role in cell adhesion, pH regulation and dedifferentiation of the tumours. Here we investigated whether there is cross talk between the HIF-1 and Wnt...

In purpose to elucidate pathogenetic mechanisms of congenital forms of hypogonadotropic hypogonadism we have examined 25 women with idiopathic hypogonadotropic hypogonadism (IHH), mean age 26 years and 7 months (group 1). All patients had amenorrhea, little breast development (Tanner 2–3), absence or little axillery and pubic hair, infantile uterus and decreased ovary volume. There were no pathological changes during MRI-investigation. Twenty healthy women were included i...

Up to date, 12 patients with sporadic non-autoimmune hyperthyroidism (SNAH) caused by sporadic germline mutations in the TSHR gene have been reported. Nearly, all case reports discussed possible associations of the TSHR mutations in vitro activity (IVA) with the clinical course (CC). Therefore, we analyzed this question in a systematic review of the case reports and investigated the TSHR mutation’s IVA in selected cases.Recently, linear regre...

Animals that are socially isolated for extended periods show behavioural and physiological changes, including alterations in hypothalamo-pituitary-adrenocortical (HPA) activity. However, there is conflicting data regarding the effects of social isolation on the HPA axis, with studies indicating increased1, decreased2 and unchanged3 corticosterone levels following social isolation. We investigated the effects of social isolation on HPA activity ...

Initial clinical trials with pegvisomant at doses of up to 80 mg once weekly led to a 30% fall in IGF-I. Subsequently, daily administration of up to 40 mg/day (280 mg/week) achieved an IGF-I within reference range in 97% of patients. Pegvisomant’s half-life is >70 h suggesting weekly dosing may be possible using higher doses than in the original trials.We performed a two-centre, open-label prospective study in seven patients (4M, 3F, mean age 57...

Background: Tissue hypoxia is a hallmark of rapidly proliferating tumours which most frequently adapt and prosper under low oxygen tension. The transcription factor, HIF-1α, is mediating these effects and induces target genes involved in survival, invasion and resistance to drugs and radiation. No data are available on the functional regulation of HIF-1α in thyroid carcinoma cells.Methods: Using thyroid carcinoma cells derived from papillary (N...

Background: Parathyroid carcinoma (PC) is an infrequent pathology, responsible for 0.5–5% of primary hyperparathyroidism cases. Despite the high prevalence of secondary hyperparathyroidism in patients with a chronic kidney disease (CKD), PC among them is extremely rare, with less than 30 cases reported in the literature. The diagnosis of PC in CKD patients is more complex, because of using cinacalcet that reduces the level of calcium and parathyroid hormone (PTH). We repo...

Objective: To determine the effect of glycemic variability on cognitive function in patients with type 1 diabetes mellitus.Materials: Thirty patients with type 1 diabetes mellitus were examined at the age of 29.7 (27.45–30.4) years, the duration of the disease was 19 (15.1–20.3) years. Patients were divided into 2 groups: 1st group (n=15) – patients with cognitive impairment, 2nd group (n=15) – without.<p class="...

BackgroundThere are no specific markers for parathyroid carcinoma (PC) therefore, the development of algorithms for identifying high-risk patients is an urgent task.AimsTo determine clinical and laboratory predictors of PC and identify the factors of a poor prognosis.Materials and methodsA multi-center retrospective study included 242 patients with primary hyperpa...
