Introduct&idot;on: Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by damage to β cells in the pancreas. Neopterins and indolamine 2,3-dioxygenase (IDO) activity, which is shown by the ratio of kynurenine to tryptophan, can be used as an indicator in the regulation of cellular immunity. Oxidative stress produced by xanthine oxidoreductase has been shown to be associated with vascular endothelial dysfunction. It uses the conversion of p...

Down syndrome (DS) is the most common chromosomal disorder in live births (1/1500-1/700) and caused by a meiotic nondisjunction (trisomy 21). DS is associated with an increased risk of thyroid disorders in addition to other systemic problems. In this study, we aim ed to investigate the thyroid hormone profiles and associated autoimmune diseases in DS.Material and Method: DS patients, aged 0-18 years, who were followed for thyroid problem...

Objective: Congenital Hyperinsulinism(CHI) is a clinically, genetically, and histologically heterogeneous disease. Turkey is a county with highly prevalent cases of severe CHI due to the high rate of consanguinity and recessively inherited KATP gene mutations. We herein evaluated the clinical characteristics, molecular genetic analysis, and follow-up of a large nationwide cohort of CHI from Turkey.Patients and method: Th...

Background: Disorders related to an impairment in parathyroid hormone (PTH) signaling pathway are historically classified under the term pseudohypoparathyroidism (PHP), that now encompasses rare, related but highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and an in vitro assay of Gs&#9...

Background: Rare metabolic bone diseases (RMBD) are at the crossways of Endocrinology, Nephrology, Orthopaedic surgery and Rheumatology. Most of RMBD lead to short stature, bone pain, tooth anomalies, leg deformities, bone fragility and disability of variable importance. The organization of care varies immensely amongst European countries. Several European networks dedicated to RMBD already exist, supported by societies such as ESPE, ECTS or research grants, albeit their focus...
