Background: There exists no gold standard for adjustment of treatment in congenital adrenal hyperplasia. Clinicians try to avoid over-and undertreatment by considering various indicators. We aimed to investigate the sampling times of 17-hydroxyprogesterone (17-OHP) and the use of sex hormone-binding globulin (SHBG) as a monitoring parameter, the association of which was not studied with clinical features. Materials and Methods: This cross-sectional study inclu...

Elevated Anti-tissue Transglutaminase Antibodies in Children Newly Diagnosed with type 1 Diabetes do not Always Indicate Celiac Disease

Paketçi Ahu , Armagan Coskun , Erbas İbrahim Mert , Demir Korcan , Abaci Ayhan , Böber Ece

Introduction: The prevalence of celiac disease is 5–10 times higher in patients with type 1 diabetes mellitus (DM) than in the general population. Therefore, celiac serology should be screened intermittently in type 1 DM patients. However, anti-tissue transglutaminase (anti-TTG) antibody elevation may be detected incidentally at the time of type 1 DM diagnosis and regress spontaneously during follow-up, without medical or dietary interventions.<p clas...

Yildiz Melek , Isleten Figen , Demir Korcan , Celik Nilufer , Korkmaz Huseyin Anil , Tuglu Birsen , Elmas Ozlem Nalbantoglu , Ozkan Behzat

Background: Type 1 diabetes mellitus is characterized by presence of several organ specific autoantibodies. Anti-cyclic citrullinated peptide (anti-CCP) antibody is a promising marker of rheumatoid arthritis (RA) which is known to coincide with autoimmune diabetes. Presence of these antibodies was not investigated in children with type 1 diabetes.Objective and hypotheses: To evaluate presence of anti-CCP antibodies in children with type 1 diabetes compar...

Tunc Selma , Demir Korcan , Hazan Filiz , Kirbiyik Ozgur , Soyaltin Eren , Nalbantoglu Ozlem , Yildiz Melek , Korkmaz Huseyin Anil , Ozkan Behzat

Aim: Acrodysostosis is a rare genetic syndrome characterized by small hands and feet with short, stubby fingers and toes, cone shaped epiphyses, broad nasal root, various abnormalities of mandible, skull, and vertebra, short stature, and mental retardation. Because of the hormone resistance that would accompany, acrodysostosis can be confused with pseudohypoparathyroidism. Mutations of PRKAR1A and PDE4D are reported to be responsible for the disease in less t...

Background: The exact mechanism of the partial clinical remission in type 1 diabetes mellitus (T1DM) has not been elucidated yet. The severity of the inflammation at the time of diagnosis may have an impact on the occurrence or duration of this phase.Objective: We aimed to investigate the relationship between hematological inflammatory parameters at the time of diagnosis in children and adolescents with T1DM and the need...
