This work aimed to evaluate pituitary–adrenal axis and tissue metabolism of cortisol in patients with long standing type one diabetes.Fifty patients with diabetes type 1 were investigated; age 38±10 years (mean±S.D.), age at diagnosis 25.5±10 years, disease duration 15±8 years, BMI 24.5±2.7 kg/cm2, HbA1c 7.2±1.2%. Control group consisted of 40 healthy volunteers.The study...

Aim: To study the insulin sensitivity and secretion in women with polycystic ovary syndrome (PCOS).Subjects and methods: Thirty-eight women with PCOS (age 26.1±4.1 years, BMI 20.9±2.0 kg/m2) and 81 control healthy women (age 25.8±5.2 years, BMI 21.1±2.3 kg/m2) underwent oral glucose tolerance test (OGTT). Insulin resistance was evaluated as oral glucose index (OGIS); Matsuda and HOMA-IR, insulin secretion was cal...

Introduction: The influence of steroid hormones on food intake is well described. However, there are only a few studies on the effect of food intake on steroid levels.Methods: The study involved eight non-smoker women (average age 29.48±2.99 years; average BMI 21.3±1.3 kg/m2); they did not use any kind of medication affecting steroidogenesis. We analysed the influence of four various stimuli on the levels of steroid hormones and mela...

Background of the study: There is lack of data in the Czech Republic on iodine status in patients suffering from diabetes mellitus type 1 (DM1) considered to be at risk of iodine deficiency.Subjects and methods: A total of 54 males and 51 females ‒ median (25th, 75th percentile): age (years) 42 (31, 55); BMI 25.9 (23.3, 29.7); HbA1c (mmol/mol) 61 (51.2, 71.0) treated for DM1 were included in this cross–sectional study. In addition to iodine s...

Introduction: The dependence on tobacco, diagnosis F 17, is an independent condition in the International classification of diseases and presents one of the most widespread addictions. Chronic smoking can cause impairment of fertility in both sexes. However, only a small number of studies were dedicated to the influence of smoking on levels of steroid hormones and their neuroactive metabolites. Neuroactive steroids modulate the effects of tobacco on central nervous system, and...

Introduction: Disturbances of the thyroid gland are the most common diseases of the endocrine system. Their prevalence is increasing with age and can be easily under diagnosed. Advanced forms of thyroid disease can mimic cardiovascular, psychiatric disorders, malignancy or other disorders and can result in life threatening conditions.Case reports: In the current study we present two case reports concerning patients with cardiovascular symptoms. In both p...

This work aimed at acquiring data on pituitary response to CRH test in autoimmune type 1 diabetics with adult onset with/without thyroid autoimmunity. Our previous study showed 25% of such diabetic patients without clinical and immunological signs of adrenal insufficiency had lower response to the Synacthen test with normal basal levels of ACTH and cortisol.Twenty-seven diabetics were investigated; age 44±10 years (mean±S.D.), ag...

Introduction: Cigarette smoking is one of the most serious substance abuse problems. It is generally accepted that nicotine and other chemicals in tobacco smoke alter endocrine functions in men and adverse reproductive outcomes, including deterioration of sperm. Studies on the effects of smoking and smoking cessation on male sex hormones are inconsistent. We studied changes of hormonal levels in men during smoking cessation and we looked for a possible predictive marker of suc...

Introduction: Cigarette smoking is one of the most serious substance abuse problems. It is generally accepted that nicotine and other chemicals in tobacco smoke alter endocrine function in women, induce changes in female hormonal balance and likely contributes to reported associations of smoking with adverse reproductive outcomes, including menstrual dysfunction, infertility, and earlier menopause. Studies on the effects of smoking and smoking cessation on female sex hormones ...

This work aimed at gathering own data on adrenal response to low-dose Synacthen test, CRH test and about periferal metabolism of cortisol in autoimmune type 1 diabetics with onset in adults. Seventy diabetics were investigated; age 44±10 years (mean±S.D.), age at diagnosis 28.5±10 years, disease duration 15±8 years, BMI 24.5±2.7 kg/cm2, HbA1c 7.2±1.2%. The study was approved by the Ethical Committee. Adrenal reserve was t...
