Introduction: Several studies have investigated determinants for androgen levels in men, but few studies have included women. Epidemiological evidence has suggested that cigarette smoking has an anti-oestrogenic effect in women, but the effects of smoking on steroid hormone metabolism are not fully understood. We investigated whether there is a relationship between androgen levels and smoking in perimenopausal women.Material and methods: We examined 75 p...

Parathyroid glands are critical not only for regulation of the phosphorous-calcium metabolism, but also have a key role in the function of nervous, cardiovascular, digestive and other human body systems. Parathyroids are capable of accumulating the isotopes of cesium, strontium and radioactive iodine, which can lead to parathyroid cell damage and emergence of glandular dysfunction. Significant radioactive environmental releases and fallout after the Chernobyl NPP accident in 1...

Hypoglycaemia stimulation serves as a model of physiological function of adrenal action during the stress reaction. The study aimed to describe the differences of steroid response between hypoglycemia and various doses of Synacthen (as ACTH stimulation alone). The goal of the study was to investigate the physiology of adrenal response. Twenty four steroids were measured in plasma using gas chromatography - mass spectrometry after stimulation of 1 μg, 10 μg and 250 &#...

The adrenal androgens dehydroepiandrosterone, dehydroepiandrosterone sulfate, androstenedione, 5-androstenediol and 11β-hydroxy-androstenedione have a wide spectrum of important physiological effects. Aim of our study was to find differences in reaction of the C19 Δ5-steroids between healthy women and patients with adrenal insufficiency in various doses of Synacthen (1 ug, 10 ug and 250 ug). Our study involved seven healthy women and six premenopausal females (BMI an...

Case report: Hirsutism although common in acromegaly (24%) is not considered as the prevalent symptom of the disease. Here we describe a seventy-one year old woman with a 2-year history of hyperandronism and subtle acromegalic features (macroglossia, sleep apnea). Clinical examination showed hirsutism (Ferrimann-Gallwey score 20/34), acanthosis nigricans and mild clitoridomegaly. Blood examination revealed elevated IGF-1: 502 ng/ml (69–200 ng/ml) and standard oral glucose...

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common feature of type 2 diabetes mellitus (T2DM). Liver fibrosis has been associated with an increased risk of cardiovascular diseases (CVD).Aim: To investigate whether the fibrosis 4 index (FIB-4), a non-invasive marker of liver fibrosis, is associated with CVD or cancer in patients with T2DM.Methods: Two hundred and nine consecutive T2DM patients...

Introduction: Non-celiac gluten sensitivity (NCGS) belongs to gluten-related disorders. Patients with NCGS develop a variety of intestinal and/or extraintestinal symptoms such as abdominal pain, bloating, bowel habit abnormalities, nausea, gastroesophageal reflux disease and aphthous stomatitis, that improve when gluten is removed from the diet. The diagnosis is made after exclusion of coeliac disease and wheat allergy. Although thyroxine malabsorption has been described in pa...

Background: Diabetic ketoacidosis (DKA) has been associated with severe hemolysis in patients with Glucose-6-phosphate dehydrogenase (G6PD) deficiency after restoration of euglycemia. Less than 30 cases have been reported so far. The exact mechanism is not fully understood.Case presentation: A 35-year-old African American man presented to the emergency department with polyuria, polydipsia, abdominal pain and weight loss the last 15 days. Physical examina...

Background: Infection with the human immunodeficiency virus (HIV) predisposes to endocrine disorders, manifesting as a metabolic phenotype that affects the entire adipose-musculoskeletal unit (AMS). The present cross-sectional study aimed to investigate differences in irisin and adiponectin concentrations between people living with HIV and healthy controls, as well as to explore potential correlations between the levels of the aforementioned adipokines and markers of calcium h...

Background and aims: Vitamin D deficiency during the perinatal period has been hypothesized to increase risk for several psychiatric disorders in humans. As newborn vitamin D levels are entirely dependent on maternal vitamin D status, vitamin D deficiency in utero may leave the infant vulnerable to cognitive defects and behavioral problems. Few human studies have examined these associations with inconclusive results. We aimed to investigate the associations of maternal 25-hydr...
