Owing to the difficulties in proper diagnosis of male hypogonadism, there is an ongoing debate on treatment needs of these patients. The comparison of commonly quoted thresholds of serum total testosterone concentrations for considering testosterone replacement therapy surprisingly reveals different thresholds in different European countries. The lower limit of ‘normal’ serum testosterone is 10 nmol/l in Germany, 7.5 nmol/l in France, 7.5–8 nmol/l in the UK, and...

Objective: We aimed to evaluate the ability of SAGIT Instrument and AcroQoL questionnaire to discriminate acromegaly control status and to correlate SAGIT scores to AcroQoL results in a cohort of the national referral centre.Methods: Cross-sectional study included 72 patients followed between 2000 and 2020. We retrospectively determined SAGIT score at the diagnosis. Based on the data from the most recent follow up and additional telephone interviews, we ...

Background: Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder of multifactorial etiopathology likely to involve the interactions between genetics and lifestyle. Chronic inflammation and oxidative stress (OS) may participate in the pathophysiology of the syndrome. The question of the extent to which OS and inflammation are causally related to the development of the syndrome and metabolic complications remains unanswered. Furthermore, the role of NLR...

CaSR-autoantibodies may cause auto-immune hypercalcemia through either simple blocking or biased properties. The phenotype of this rare disease is most often acquired hypocalciuric hypercalcemia (AAH) (Minanbres JCEM 2020, Makita JCI insight 2022), but sometimes hyperparathyroidism (Pelletier-Morel Intern Med 2008), in elderly. Gender, auto-immune context is variable. Blood calcium may fluctuate, and acute exacerbations may be successfully treated with predni...

Background: Chemerin (CHEM) is a newly-discovered adipokine involved in the immune, metabolic and reproductive processes. Low-grade state inflammation (LGSI) is a key element in the pathogenesis of metabolic syndrome (MS).Objectives: The aim of the study was to assess the effect of age on MS prevalence, androgenic status as well as on selected inflammatory indices and CHEM plasma concentrations. Additionally we investigated correlations between CHEM and ...

Introduction: Given the importance of establishing a reliable diagnosis of impaired glucose metabolism and diabetes mellitus (DM), knowledge on accurate and reproducible parameters is needed. However, little is known on the reproducibility of fasting and oral glucose tolerance test (OGTT) derived parameters, especially with respect to the 2-hour derived parameters.Objectives: To determine reproducibility of parameters of glucose metabolism in a non-diabe...

Introduction: VPA, antiepileptic drug, may cause a number of side effects including reproductive deficits in humans. Previously we found that VPA (1 μM) may suppress GnRH-stimulated release of LH from rat anterior pituitary cells in vitro without affecting its basal secretion (Neuroendocrinol Lett 2011 32 101–106). However mechanism of VPA suppressive activity is still unknown. Since pharmacological effects of VPA require GnRH-R activation, the m...

Intrathyroidally located parathyroid carcinoma is extremely rare cause of primary hyperparathyroidism. Multifocal papillary and follicular thyroid carcinomas are rather common.We report a case of 40-year old man presenting with substantial weight loss, anemia and multiple osteolytic lesions of both tibias. Peak serum calcium level was 5.0 mmol/l, parathyroid hormone (PTH) level was 989 pg/ml. Left thyroid lobe was firm and enlarged. Routine percutaneous ...

Aims: The aim of our study was to assess the relationships between systemic markers of general inflammation: interleukin 18 (IL-18) and C-reactive protein (CRP) and dehydroepiandrosterone (DHEA) as well as dehydroepiandrosterone sulphate (DHEA-S) serum levels, in addition to the anthropometrical and biochemical indices of metabolic syndrome (MS) in men over the age of 40.Patients and methods: In 271 randomly chosen men aged 40 to 80 years living in Lubus...

Background and aims: Dehydroepiandrosterone fatty acid esters (DHEA-FAEs) belong to a unique family of naturally occurring hydrophobic steroid hormone derivatives with long-lasting hormonal activity. DHEA-FAEs function through hydrolysis of DHEA-FAEs into free DHEA and further metabolized to biologically active steroids. The lysosomal acid lipase (LAL) mediates the intracellular hydrolysis of cholesterol esters. This study aims to study the possible role of LAL on the hydrolys...
