Kurt Ilknur , Eser Metin , Kahveci Ahmet , Ucar Ahmet , Bulus Derya , Ozcabi Bahar , Guran Tulay

Background and objective: 21alpha-hydroxylase deficiency congenital adrenal hyperplasia (21OHD-CAH) is the most common etiology of inherited primary adrenal insufficiency (PAI) in children. Neonatal CAH screening is important for early diagnosis of salt-wasting 21OHD and other virilizing CAH (11beta-hydroxylase, 3beta-hydroxysteroid dehydrogenase deficiencies) and for avoiding mortality, especially in salt-wasting CAH. Neonatal CAH screening has become nationw...

Gulderen Kalay Şenturk Nida , Cakır Aydilek Dağdeviren , Yıldırmak Zeynep Yıldız , Ucar Ahmet ,

Objective: Spexin is a novel peptide implicated in food intake and satiety. Spexin levels are reduced in obese patients.Aim: To evaluate the associations of metabolic syndrome (metS) antecedents with serum spexin levels in obese adolescents.Setting: A university- based tertiary care centre.Patients and methods: Eighty consecutive obese adolescents aged 10-18 y and 80 healthy ...

A rare cause of acquired von Willebrand factor deficiency: Primary hypothyroidism due to autoimmune thyroiditis

Dağdeviren Çakır Aydilek , Yıldız Yıldırmak Zeynep , Eren Simge , Mısırlı Özdemir Ebru , Özdemir Mustafa , Ucar Ahmet

In children, autoimmune thyroiditis is often diagnosed with signs and symptoms such as goiter, short stature, and constipation. Delayed diagnosis of hypothyroidism may result in atypical signs and symptoms at presentation, depending on the severity of hypothyroidism. Von Willebrand disease (vWD) is the most common bleeding disorder caused by the quantitative or qualitative deficiency of von Willebrand factor (vWF). Acquired vWD (avWD) is a disorder characterized by low levels ...

Evaluation of the Glucocorticoid, Mineralocorticoid, and Adrenal Androgen Secretion Dynamics in A Large Cohort of Patients Aged 6–18 Years with Transfusion-dependent β-Thalassemia Major, with an Emphasis on the Impact of Cardiac Iron Load

Ucar Ahmet , Oner Nergiz , Ozek Gulcihan , Cetincakmak Mehmet Guli , Abuhandan Mahmut , Yildirim Ali , Kaya Cemil , Unverdi Sena , Emeksiz Hamdi Cihan , Yilmaz Yasin , Yetim Aylin

Background: The variable presence of adrenal insufficiency (AI) due to hypocortisolemia (HC) in patients with thalassemia is well established; however, the prevalence of adrenocortical hypofunction (ACH) in the zona glomerulosa and zona reticularis of the adrenal cortex is unknown.Objective and hypotheses: To establish the prevalence of ACH, we examined the cortisol response to 1 μg- and 250 μg- ACTH tests, plasma aldosterone (A)/plasma renin a...

Background: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires accurate diagnosis and urgent treatment. Congenital adrenal hyperplasia is the most common cause of PAI in children. Non-CAH causes of PAI are relatively rare. Although several molecular causes have been found, it is emerging that considerable overlap in the clinical and biochemical features of these conditions exists.Objective and hypotheses: We inv...
