Relation between Levels of Atymullerian Hormone and Inhibin B and Spontaneous Puberty in Patients with Turner Syndrome – Preliminary Results

Ruszała Anna , Wójcik Małgorzata , Starzyk Jerzy B.

Introduction: Primary hypogonadism is stated as one of major features in patients with Turner Syndrome (TS), however it is not a constant finding. Variable markers of ovaries failure in TS patients are still missing. The present study aimed to evaluate the usefulness of atymullerian hormone and inhibin B assessment in predicting spontaneous puberty in patients with TS.Methods: The study included 35 TS patients. Gonadal a...

Inhibin B in the Diagnosis of Delayed Puberty

Procopiuc Camelia , Gherlan Iuliana , Dumitrescu Cristina , Brehar Andreea , Vladoiu Suzana , Procopiuc Livia , Caragheorgheopol Andra

Background: Existing tests are not 100% accurate in differentiating between isolated hypogonadotropic hypogonadism (HH) and constitutional delay of puberty (CDP) in boys. Inhibin B is a glycoprotein produced by the Sertoli cells and is measurable even before puberty. Its level increases at the beginning of puberty under the influence of FSH.Objective and hypotheses: The levels of inhibin B (InhB) could differentiate between HH and CDP. We aimed to establ...

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...

Paternal Isodisomy and Sporadic Pseudohypoparathyroidism I-b

Colson Cindy , Brehin Anne Claire , Abeguile Genevieve , Decamp Matthieu , Richard Nicolas , Kottler Marie-Laure

Background: Patients affected by pseudohypoparathyroidism type 1b (PHPI-b) develop resistance to PTH leading to hypocalcemia and hyperphosphoremia, which is often associated with resistance to TSH. PHP-Ib is associated with methylation changes at one or several differentially methylated regions (DMRs) within the GNAS complex locus, located at 20q13.2–13.3. This locus gives rise to several different transcripts (NESP55, XL, A/B), with varying patterns of imprinted expressi...

Ön S.Sebnem , Acar Sezer , Demir Korcan , Abaci Ayhan , Öztürk Yesim , Çelik Sinem Kahveci , Böber Ece

Backgrounds/Aims: Studies related to changes in thyroid hormone metabolism in the course of chronic liver diseases have been conducted mostly in adults. In this study, we aimed to investigate the thyroid dysfunction in childhood chronic liver diseases.Methods: Between 2005 and 2018, 960 chronic liver disease patient file that followed in our gastroenterology department are reviewed. Among all study subjects, 107 (53 fema...

Papillary Thyroid Cancer Associated with Hyperthyroidism

Acar Sezer , Paketçi Ahu , Demir Korcan , Ates Oguz , Özer Erdener , Özdogan Özhan , Böber Ece , Abaci Ayhan

Introduction: The most common causes of hyperthyroidism in the pediatric age group are autoimmune conditions (Graves' disease or Hashitoxicosis). Hyperfunctioning thyroid carcinomas are rarely reported. In this case report, we present a 17-year-old girl who was diagnosed with papillary thyroid carcinoma upon testing for hyperthyroidism.Case: A 17-year-old girl had presented to another center with a 1-month history of...

A Rare Cause of Hypogonadotropic Hypogonadism: FGFR1Mutation

Mert Erbaş İbrahim , Paketçi Ahu , Acar Sezer , Kotan Damla , Demir Korcan , Abaci Ayhan , Böber Ece

Introduction: Mutations in FGFR1, which is involved in formation and migration of neurons responsible for the production of gonadotropin-releasing hormones, may either cause isolated hypogonadotropic hypogonadism (HH) or Kallmann syndrome (KS). In addition, FGFR1mutations were reported in 2.7% of the cases with multiple pituitary hormone deficiency.Case: A 16-year-old male was referred to our clinic...

Evaluation of Clinical, Demographic Data and Treatment Results of Cases with Graves' Disease

Introduction: Graves' disease is the most common cause of hyperthyroidism in children and adolescents, characterized by development of stimulant antibodies against thyrotropin (TSH) receptors. Environmental and genetic factors are thought to be responsible in triggering autoimmunity.Materials and Methods: Twenty-nine cases, with Graves' disease diagnosed in Pediatric Endocrinology clinic between January 1999 and ...

Inhibin B- a functional marker to screen gonadal function in CAIS patients?

Viola Wagner Isabel , Tyutyusheva Nina , Bertelloni Silvano , Doehnert Ulla , Simon Frielitz Fabian , Hiort Olaf

Introduction and objective: Gonadectomy was carried out for a long time after the diagnosis of complete androgen insensitivity syndrome (CAIS). It is now recommended to leave the gonads in situ in order to guarantee endogenous hormone production. It is unclear how best to clinically monitor testicular function. The aim of the study was to investigate whether inhibin B can be used as a future follow-up parameter to screen for gonadal function in CAIS p...

Serum Estradiol is Associated with Inhibin B in Healthy 1-6 Years Old Girls

Birkebaek Niels H. , Schørring Mia E. , Frederiksen Hanne , Kamperis Konstantinos , Kristensen Kurt , Rittig Søren , Juul Anders , Vestergaard Esben T

Background: The female gonadal axis is activated in mini-puberty and thereafter it is quiescent until puberty. We have shown that many girls with no clinical sign of puberty in the age group 1-6 yr. have a rather strong luteinizing hormone (LH) and follicle stimulating hormone (FSH) response to a gonadotropin releasing hormone (GnRH) test. However, stimulated LH and FSH values decreased in the age interval 1-6 yr and no LH/FSH values rose above 0.43. Serum est...
