Introduction: Increased cytokine release, impaired antioxidation and reactive oxygen species (ROS) have been shown in β-cells in pathogenesis of T1DM. Increased ROS leads to formation of covalent bonds between the sulfur atoms, leading to disulphide conversion. Displacement to disulphide form of this thiol/disulphide balance starts the oxidative damage. This study evaluates the thiol/disulphide balance in children with T1DM.Material...

Background: The most common form of congenital adrenal hyperplasia is 21-hydroxylase deficiency (CAH). In women with classic CAH, the fertility rate is lower than in the general female population, and an increased rate of miscarriages has been reported. There are no data on the incidence rate of miscarriages in families with an offspring that have classic CAH.Methods: The families came from different parts of Germany and attended the annual meeting of th...

Background: Vitamin D status in children with isolated GHD has been analyzed in few studies with controversial results. The aim of the study was to assess vitamin D status in children with idiopathic GHD in North and Central Greece.Materials and methods: 128 children (M/F: 76/61, mean age 9.5 (S.D.±3.5 years) with isolated GHD were compared with 65 controls (M/F: 46/3, mean age 9.3 (S.D.±3.2 years). Children were d...

Background: Type 1 diabetes mellitus (T1DM) is the most common endocrine disease in children and adolescents.Objective and hypotheses: It was aimed to evaluate the frequency of autoimmune thyroiditis (AT) and the possible risk factors for AT at diagnosis and at follow up of T1DM patients.Method: T1DM patients who were admitted to Trakya University Medical Faculty Pediatric Department, Pediatric Endocrinology Outpatient Clinic betwe...

Background: Disorders (or differences) of sex development (DSD) are rare congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. The luteinizing hormone/chorionic gonadotropin receptor (LHCGR) is important for male sex development. LHCGR mutations can cause Leydig cell hypoplasia, which is an autosomal recessive disorder.Objective and hypotheses: We found two heterozygous mutations in the LHCGR, a n...

Background: Antimüllerian hormone (AMH) is produced by granulosa cells surrounding follicles. There are limited studies about the change of AMH levels at the pubertal onset.Objective and hypotheses: The aim of this study was to identify whether AMH levels could be diagnostic for central precocious puberty (CPP), premature thelarche and premature adrenarche (PA) and to investigate the factors influencing AMH regulation.Method: ...

Background: Congenital isolated GH deficiency (cIGHD) is a rare genetic disease occurring mostly in consanguineous families. It is caused by hGH-1 gene deletion or GHRH – receptor mutations.Aim of study: To collect retrospectively size at birth, developmental mile stones, linear and head growth and pubertal development before and during hGH treatment.Subjects: The medical charts of 37/41 patients with cIGHD (21 m, 16 f) contai...

Background: There is wide geographic variation in the frequency of diabetic ketoacidosis (DKA) at onset of diabetes from ~15–70% in Europe and North America.Objective and hypotheses: To evaluate the frequency of DKA at the onset of type 1 diabetes (T1D) in the paediatric population seen in the Department of Pediatric Diabetology of Turin (Italy) from 1/1/2008 to 31/12/2013.Method: Data (venous pH and HCO3, season at the onset)...

Background: Non-alcoholic fatty liver disease (NAFLD) in obese children is a diagnostic challenge. Presently recommended markers of liver steatosis and risk of progression to fibrosis are: ultrasound imaging (US) and liver aminotransferases (ALT and AST). Owing to the poor sensitivity of these tests, there is a need to search for biomarkers which could indicate early stages of NAFLD. The enhanced liver fibrosis test (ELF) based on the combination of serum concentration of hyal...

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...
