An increasing interest in improving the quality of life of patients with autoimmune thyroid disorders has been noted during recent years. Although there is little scientific evidence, many patient-oriented publications, websites and support groups recommend changes in diet as well as nutritional supplement use as a cure for thyroid disease and the mean for ailments reduction. The presented survey aimed to explore the patients’ and medical professionals’ approach to n...

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: Efficacy and safety of combination treatment of pasireotide LAR with pegvisomant (PEGV) has not been studied yet. Switching to Pasireotide LAR in patients previously controlled with long-acting somatostatin analogues (LA-SSAs) and PEGV could reduce the required PEGV dose to normalize serum IGF1 levels, while the effect on glucose metabolism is unknown.Methods: We enrolled 60 acromegaly patients >18 years with acromegaly who had normal IGF...

Metabolic reprogramming resulting in significant alterations of the energy metabolism is a hallmark of prostate cancer (PCa). In this study we performed a comprehensive metabolic analysis of various human (LNCaP, DuCaP, PC-3, Du145) and murine PCa cell lines differing in the expression of the tumor suppressor phosphatase and tensin homolog (PTEN). In line with previous studies we found that PTEN- PCa cells (LNCaP, PC-3) had a higher glycolytic activity than PTEN<sup...

Background and aim: Up to now, there is paucity of studies concerning health status in adults with congenital adrenal hyperplasia (CAH). We aimed to examine a group of adult CAH patients from different Czech centers.Methods: Serum lipids, glucose, blood pressure and anhtropometrics were compared in 31 males and 71 females with CAH 21-hydroxylase deficiency and in healthy population from Czech post-MONICA study (1% random population sample).<p class="...

Background: Congenital adrenal hyperplasia (CAH) is the underlying diagnosis in most newborns presenting with 46,XX disorders of sex development (DSD). Cytochrome P450 oxidoreductase deficiency (PORD) is a rare form of CAH caused by inactivating mutations in the POR gene. The hallmark feature of PORD is combined sex-steroid and glucocorticoid deficiency due to impairment of CYP17A1 and CYP21A2. Skeletal malformations resembling the Antley-Bixler Syndrome phenotype are common i...

Case 1: A 65-year-old man was admitted with symptomatic hypocalcaemia (corrected calcium of 1.65 mmol/l, PTH 46.6 (1.6–6.8) pmol/l, and vitamin D 51.4 (50–150) nmol/l)) 5 days following denosumab initiation. He had a diagnosis of probable urothelial carcinoma with associated osteoblastic metastases, and 10 days prior to this admission had been treated for hypercalcaemia (corrected calcium of 3.04 (2.20–2.60) mmol/l) with i.v. fluids following which denosumab was...

A 31-year-old woman presented with oligomenorrhoea and a raised prolactin. Pituitary scan revealed a 1.8 cm pituitary mass with compression of the optic chiasm. TSH was normal at 3.66 mIU/l with a raised FT4 of 25.8 pmol/l. The rest of pituitary function was normal. Visual fields demonstrated a bitemporal upper quadrantanopia. A diagnosis of TSH-secreting pituitary adenoma was suspected because of the high normal TSH in the presence of a high FT4. She und...

: A 61-year-old gentleman was referred to the Endocrine team with acute bilateral adrenal haemorrhage. He had undergone a successful left popliteal embolectomy for critical limb ischaemia a week ago following which he was commenced on anticoagulation therapy. He presented to the Emergency Department with acute severe abdominal pain and low grade pyrexia of 37.6 C. He was haemodynamically stable. His International Normalised Ratio was noted to be elevated at 4.7. An urgent abdo...

The peptides acylated and unacylated ghrelin (AG and UAG) are produced predominantly in the stomach. AG is the only known circulating orexigenic hormone with obesogenic and insulin-desensitising properties. Recent evidence suggests that UAG can inhibit these activities of AG. To investigate potential inhibitory effects of UAG and AZP-531, a UAG analogue, on AG-induced appetite and obesity we used an established rat model of diet induced obesity. Animals were fed a high-fat die...
