Introduction: Primary aldosteronism (PA) is a group of disorders which are characterized by inadequate and non-suppressible production of aldosterone. The prevalence of PA is increasing in hypertensive population. The golden standard of screening for primary aldosteronism, determination of aldosterone/plasma renin activity (ARR), is influenced by numerous exogenous and endogenous factors. Testing cannot always be conducted under optimal conditions.Object...

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. It is a heterogeneous disorder characterized by oligo- or anovulation (ANOV), biochemical or clinical manifestations of hyperandrogenemia (HA) and polycystic ovaries (PCO). Combination of these three characteristics makes four phenotypes of PCOS: phenotype 1 (ANOV+HA+PCO), phenotype 2 (ANOV+HA), phenotype 3 (HA+PCO) and phenotype 4 (ANOV+PCO). The difference...

Introduction: After gastric bypass, gastric secretion decreased and resorption of minerals and vitamins may be compromised. Lower resorpion of serum calcium and vitamin D could stimulate PTH secretion after restictive and malabsorptive bariatric procedures.Methods: We have measured serum calcium, D vitamin and PTH in patients (n=50, 17 males and 33 females) 6 and 12 months after R en Y gastric bypass, 38.6±12.6 years of age, with BMI 43&#17...

According to the novel concept bone remodeling is centrally regulated (CNS). Leptin the adipocyte derived hormone acts on hypothalamus and by increasing sympathetic activity acts on osteoblasts to regulate bone formation. In patients with schizophrenia several factors have influence on bone metabolism. Schizophrenia per se, as a disease of central nervous system is associated with increased occurence of osteoporosis. Hyperprolactinemia as consequence of antipsychotic tr...

Spontaneous subarahnoid hemorrhage (SAH) is a recently identified risk factor for hipopituitarism, especially growth hormone (GH) and corticotroph deficiencies. The aim of this study is to perform the initial screening procedure to identify the patients with increased risk of neuroendocrine dysfunction after SAH in the chronic phase and to identify the possible predictor(s) for neuroendocrine dysfunction. Ninety-one patients (30 males, 61 females), age between 19 and 69 years ...

In most obese patients, obesity is associated with a low-grade inflammation of white adipose tissue resulting from chronic activation of the innate immune system and which can subsequently lead to insulin resistance, impaired glucose tolerance and even diabetes. It is still not clear role of acquired immune response in obesity and related comorbidites such as asthma, cancer or autoimmune diseases. The aim of our study was to compare level s of IL-17 and IL23 in sever obese wom...

It was postulated that different therapeutic approaches could influence the markers of inflammation in obesity but it is unknown whether overweight women with and without metabolic syndrome have the same degrees of inflammatory state. The aim of our study was to compare level of hs-CRP in obese women without other components of metabolic syndrome with hs-CRP in women with metabolic syndrome (according IDF criteria). Overweight body mass index-matched women without (OW)) (n<...

It was speculated that androgen levels and insulin resistance may have influence on ghrelin levels. Elevated, normal and low ghrelin levels were reported in women with polycystic ovary syndrome (PCOS). The aim of our study was to investigate the basal ghrelin levels in lean patients with PCOS and to evaluate possible correlations between ghrelin levels, insulin resistance and, androgen levels. In 10 lean PCOS patients (BMI 20.45±0.51 kg/m2, age: 21.4±0.85 ...

We have previously shown impaired neuroendocrine responses to ghrelin in patients with AN. The aim of this study was to investigate the metabolic responses during infusions of active ghrelin in severly malnourished patients with AN and compare them with responses of amenorrhoic AN patients who recovered body weight (PRAN) and constitutionally thin subjects (CTS) with regular menstrual cycles and without history of eating disorder and recent weight loss. Study was approved by t...

Background and aims: Foot lesions (amputations, ulcerations) are the consequence of neuro-vascular complications. Cardiovascular risk factors are similar for both. Thus, we carried out a prospective 5-year study to examine the effects of established complications and classical risk factors on mortality in diabetic patients.Materials and methods: During the previous 5 years we analyzed 244 patients attending a diabetes clinic. The International Working Gr...
