OBJECTIVE The relation between vitamin D and autoimmune disorders has long been investigated regarding the important roles of this hormone in immune regulation. We evaluated 25-hydroxyvitamin D (25OHD) status in subjects with Hashimoto's thyroiditis (HT) and healthy controls. METHODS Group-1 included 180 euthyroid patients (123 females/57 males) with HT(More)
BACKGROUND Women with polycystic ovary syndrome (PCOS) have higher risk for cardiovascular disease (CVD). Copeptin has been found to be predictive for myocardial ischemia. We tested whether copeptin is the predictor for CVD in PCOS patients, who have an increased risk of cardiovascular disease. METHODS This was a cross sectional controlled study conducted(More)
OBJECTIVE The aim of this study was to evaluate the effect of hyperprolactinemia on body fat, insulin sensitivity, inflammatory markers, and cardiovascular risk in patients with prolactinoma. METHODS The study included 35 untreated hyperprolactinemic patients with pituitary adenomas, and 36 age-, gender-, and body mass index (BMI)-matched healthy controls(More)
PURPOSE We aimed to compare the efficacy of three different parathyroid adenoma screening tools--high-resolution ultrasonography (USG), technetium Tc 99m-methoxyisobutylisonitrile (MIBI) parathyroid scintigraphy, and magnetic resonance imaging (MRI)--and we evaluated the factors affecting the detection success rates. METHODS Parathyroid imaging was(More)
CONTEXT Several studies have reported increased risk of cardiovascular disease due to early development of endothelial dysfunction and structural vascular changes in patients with acromegaly. OBJECTIVE The aim of this study was to evaluate subclinical cardiovascular disease with epicardial fat thickness (EFT), aortic stiffness and serum levels of cell(More)
BACKGROUND Heart type fatty acid binding protein (H-FABP) has been closely associated with acute coronary syndrome, cardiac abnormalities, stroke, and obstructive sleep disorder in previous studies. The aim of this study was to evaluate and compare the serum H-FABP levels and carotid artery intima-media thickness (CIMT) between patients with prediabetes and(More)
AIMS We aimed to investigate, circulating vaspin, apelin-12 and apelin-36 levels in subjects with metabolic syndrome (MetS) and also to search for the association of vaspin and apelin levels with insulin resistance (IR), high sensitivity C-reactive protein (HsCRP), Carotid Artery Intima-Media Thickness (CIMT) and cardiovascular risk factors. METHODS In(More)
BACKGROUND Metabolic syndrome (MetS) and visceral obesity are more prevalent in obstructive sleep apnea syndrome (OSAS). We investigated the association of visceral fat (VF) measures with the components of MetS in OSAS patients with different severity levels, according to World Health Organization (WHO, 1999), National Cholesterol Education Program Adult(More)
Obstructive sleep apnea (OSA) has long been suggested to increase the risk of development of autoimmune diseases. We investigated the prevalence of Hashimoto's thyroiditis (HT) in 245 euthyroid individuals, who were suspected of having OSA. After polysomnography, subjects were grouped according to apnea-hypopnea index (AHI) consecutively as controls(More)
