Chronic stress is a pervasive concern in the modern society. A long-term hyper activation of the hypothalamic-pituitary-adrenal (HPA) axis leads to elevated amounts of stress hormones [e.g. ACTH and glucocorticoids (GCs)]. This can incur maladaptation that eventually contributes to mental illness, cardiovascular dysfunctions, diabetes, cancer and autoimmune diseases. Emerging key players for stress adaptation of the HPA axis are stem/progenitor cell populations. In this study,...

Recently we described clinical case of 38-year-old fertile woman with sudden onset of a multiple clinical symptoms: weight gain, secondary amenorrhea, hirsutism and seizures. Adrenal tumour co-secreted high amounts of DHEA sulfate, testosterone (T) and aldosterone (A) (Matulevicius et al. 2014). The symptoms of the disease disappeared after laparoscopic removal of adrenal tumour, which proved to be an adrenocortical oncocytoma. A hypersecretion of A remained after res...

Adrenal incidentaloma is adrenal tumor incidentally discovered in the region of adrenals, usually investigating for non-endocrine disease.We attempted to find out the current situation of adrenal incidentaloma in Lithuania.The object of research – patients who visited the Lithuanian University of Health Sciences, Kaunas Clinic's Clinic of Endocrinology and Vilnius Endocrinology Center for suspected adrenal pathology in 2007–2011. The total numb...

Sexual dysfunction of type 1 diabetic (T1D) men is an area that has been rarely investigated until now. Investigation of reproductive health of young men was performed in Nordic and Baltic countries in 2003/2004 (‘The Reproductive function of Estonian, Latvian and Lithuanian young men’ (ELLY)) but analysis of sexual function was out of the target of the study. In this study we invited those presumably healthy men to participate as controls for investigation of T1D me...

Introduction: Androgen secreting adrenal tumours are rare and sometimes malignant.We report hormonal and sexual changes in 39-year-old woman with androgen secreting adrenal tumour completely healed by resection of the tumour.Case report: Androgen secreting adrenal tumour that manifested in 39-year-old woman with suddenly appeared amenorrhea, weight gain, hirsutism, epileptic seizures and elevated DHEA-S and testosterone is describe...

IL17 proinflammatory cytokine through T cell activation has prominent bone-wasting effect. Our previous results highlighted the role of IL17 in postmenopausal osteoporosis. To demonstrate the HLA allele association with the increased IL17 levels in postmenopausal osteoporosis was the object of the study.HLA class I and II alleles were measured in 64 postmenopausal women (in four subgroups: with low IL17 (1, 3) and high (>3.04 pmol/l) IL17 levels (2, ...

Introduction: Lymphoma usually occurs within lymph nodes, but in rare cases, it arises from lymphocytes that are presented within the thyroid gland. Thyroid lymphoma is rare, representing less than 5% of thyroid malignancies and less than 2% of all lymphomas occurring outside of the lymph nodes and it is more likely to occur in people with Hashimoto’s thyroiditis. In this case we present a patient with Hashimoto’s thyroiditis (HT) and thyroid lymphom...

A tightly regulated stress system is pivotal for health and the adrenal cortex is a master regulator of the endocrine stress response. The adrenal cortex is characterized by constant cell renewal in part mediated by differentiation and lineage conversion of undifferentiated cell types. To date, the contribution of stem cells to organ plasticity during stress has been implicated but is not fully understood. Recently, we were able to show that a prolonged stress exposure leads t...

Introduction: Bartter syndrome (BS) is a rare autosomal recessive disorder, with an estimated prevalence of 1 in 1.000.000. It is characterized by a primary defect in sodium chloride reabsorption in the medullary thick ascending limb of Henle’s loop. Severe hypokalemia, metabolic alkalosis, hyponatremia, hypochloremia, hyperaldosteronism, and increased urinary loss of sodium, potassium, and chloride can raise the suspicion of BS, but genetic testing is required for a defi...

Introduction: Lipodystrophic syndromes are rare and heterogeneous disorders characterized by the complete or partial deficiency of adipose tissue. They can be classified according to the extent of fat loss in generalized or partial subtypes and genetic or acquired based on the pathogenic mechanisms.Case report: A 37-year-old man was referred to our department with a history of nonalcoholic steatohepatitis associated with high levels of triglycerides (720...
