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...

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...

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...

Antimullerian Hormone and Inhibin B Markers of the Ovarian Reserve After Ovariectomy

Morandi Grazia , Piona Claudia Anita , Ben Sarah Dal , Ramaroli Diego , Cavarzere Paolo , Antoniazzi Franco , Gaudino Rossella

Background: Ovarian reserve is defined as the functional potential of the ovary, which reflects the number and quality of the follicles left in the ovary at any given time. In literature there studies about the evaluation of ovarian reserve after ovariectomy for tumors and cysts, using serum markers, such as inhibin-B, and anti-Mullerian hormone (AMH), combined to ultrasonographic markers, in adult women but none in peri-pubertal girls.Case presentation:...

AMH and Inhibin B Level in Girls with Central Precocious Puberty

Jeong Hwal Rim , Hwang Il Tae , Yi Kyung Hee

Background/aim: Anti – Müllerian hormone (AMH) and Inhibin B (INHB) are considered as possible biomarker of central precocious puberty(CPP). This study investigated serum AMH and INHB level in central precocious puberty andanalyzed clinical factors associated with these two hormone levels.Methods: In total, 48 girls with CPP and 35 age – matched prepubertal girls were enrolled in the study. The subjects were divided into two groups as CPP ...

Serum Inhibin-B Values in Boys with Unilateral Cryptorchidism and Boys with Unilateral Vanished Testis

Cortes Dina , Thorup Jorgen

Background: In some recent materials of blood samples from boys with cryptorchidism gonadotropins are higher and serum inhibin-B lower than normal. Inhibin-B is produced by the Sertoli-cells and to some extent serum values of inhibin-B reflect the state of germinative epithelium in cryptorchid testes. In boys with bilateral vanished testes the serum inhibin-B level is close to zero.Objectives and hypotheses: Aim of study was to evaluate the serum inhibin...

Changes of Serum AMH and Inhibin B Levels in Girls with Central Precocious Puberty before and During Treatment with GnRH Agonists

Oh Yeon Joung , Baek Joon Woo , Kang Min Jae , Yang Seung , Hwang Il Tae

Background: In girls with central precious puberty (CPP), the hypothalamic-pituitary-gonadal axis is prematurely activated. If the girl is treated with GnRH agonist (GnRH-a), gonadotropins levels become suppressed.Objective and hypotheses: We aimed to evaluate whether serum antimu llerian hormone (AMH) and inhibin B levels are affected in girls with CPP and whether pituitary suppression by GnRH-a affects serum AMH and inhibin B levels.<p class="abste...

Management and outcomes of congenital hyperinsulinism in infants and young children: a 5-year-experience from the tertiary referral hospital in Indonesia

Fadiana Ghaisani , Soesanti Frida , B Pulungan Aman , Tridjaja Bambang , RL Batubara Jose

Background: Congenital hyperinsulinism (CHI) is a rare condition that becomes the most frequent cause of severe and persistent hypoglycemia in infants and young children. It may lead to debilitating morbidity and mortality if being diagnosed lately. Congenital hyperinsulinism can be caused by monogenic or syndromic disorders. The prevalence of CHI in Indonesia is still unknown. However, the increasing number of cases referred to the tertiary hospital recently ...
