Introduction: Acromegaly with GH excess affects up to 20% of the patients with McCune–Albright syndrome (MAS). Surgical treatment for acromegaly in MAS is often difficult because of skull-base dysplasia. Somatostatin analogs are frequently only partially effective and GH receptor antagonist – pegvisomant is more potent in normalizing IGFI levels. Radiotherapy is controversial. Pregnancy in MAS patients is described in literature but no case of successful delivery in ...

Introduction: In the past 10 years, endoscopic resection of pituitary adenomas has become an alternative to microsurgical resection with the additional advantage of increasing the patient’s postoperative comfort. This analysis explored whether endoscopic resection can reduce the risk of postoperative neurohypophyseal dysfunction.Material and methods: We rated and compared the need to administer desmopressin during the first four postoperative days a...

Introduction: Salivary cortisol measurement, representing free cortisol, seems to be a promissing alternative method to serum cortisol. Besides its use in the diagnostics of hypercortisolism, it could be of help in evaluation of adrenocortical reserve. It might be useful especially in patients on estrogen replacement, which modulates transcortin and hence total cortisol levels.Aims: Compare the reliability of salivary vs. serum cortisol assessment during...

Certain degree of hypopituitarism has been revealed in a significant number of patients who suffered traumatic brain injuries or subarachnoid hemorrhage. Microhemorrhages, necrosis, tissue infarcts and vasoconstriction are reported as mechanism of hypothalamo-pituitary dysfunction. Assessment of hypothalamo-pituitary endocrine functions in patients with chronic subdural hematomas has not been published yet, although dysfunction of hypothalamo-pituitary unit can be expected (he...

Fibroblast growth factor-21 (FGF-21) is a novel regulator of metabolic homeostasis that improved diabetes compensation and dyslipidemia in diabetic mice and monkeys. However, little is known about its regulation in humans. Cushing’s syndrome (CS) is characterized by endogenous hypercortisolism and is often associated with numerous metabolic abnormalities. The objective of this study was to test the hypothesis that CS is associated with altered levels of FGF 21 that may in...

Radiation therapy is used in the treatment of pituitary adenomas, especially in failures of neurosurgery and pharmacotherapy to reduce the size of adenomas and normalize their hypersecretion. Conventional fractionated radiotherapy has achieved good results, but only after a long latency, with considerable postradiation morbidity and with very frequent appearance of hypopituitarism. The focal stereotactic targeting allowed by Leksell gamma-knife (LGK) was supposed to decrease t...

It is well known that hypercortisolism is associated with increased morbidity and mortality caused predominantly by vascular and atherosclerotic complications. The effect of hypercortisolism on microvasculature is less known. The aim of this study was to evaluate skin microvascular reactivity (MVR) in relation to arterial hypertension, diabetes mellitus and other possible influencing factors (fibrinolysis, oxidative stress and endothelial function) in patients with Cushing&#14...

Recent studies have shown that the co-administration of lanreotide (lan) with pegvisomant (peg) was able to normalise IGF1 secretion in patients with acromegaly who were partial responders to somatostatin analogues (SSAs).Fifty seven subjects with acromegaly (mean age 51.6±12.7 years) not previously controlled by SSAs (either treated by SSAs for at least 6 months with IGF1 > ULN, or on peg for at least 3 months) with IGF1 > 1.2 ULN (n...

Acromegaly is usually diagnosed after several years of duration. The multimodal therapy – surgery, radiotherpy, pharmacotherapy – is necessary in the majority of patients. Register of sellar tumors (RESET) collecting data of patients from eight tertiary centers in the Czech and Slovak Republics since the year 2000 was established in 2008.Aim of analysis: Evaluation of diagnostics of acromegaly and effectiveness of its treatment in a daily pract...
