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 ...

Inhibin B in the Boys with Constitutional Delay of Puberty: Relationship with Gonadotropins, Testosterone, and Anti-Müllerian Factor

Latyshev Oleg , Kiseleva Elena , Okminyan Goar , Samsonova Lubov

Objective: The aim of this study were to investigate the level of inhibin B and its relationship with testosterone, anti-Müllerian factor, basal, and GnRH-stimulated gonadotropin hormones (LH and FSH) concentration in boys with constitutional delay of puberty.Material and methods: In the study were included 15 boys (mean age 14.5±1.6 years) in Tanner stages 1–2. The investigation consists of genital examination with prader orchidometer, de...

Serum Neurokinin B Level can be Used to Differentiate Central Precocious Puberty from Premature Thelarche

Parlak Mesut , Turkkahraman Doga , Ellidag Hamit Yasar , Parlak Ayse Eda

Background: Neurokinin B and kisspeptin appear to play main roles in puberty.Aims and objectives: The aim of the present study was to investigate the diagnostic role of kisspeptin and neurokinin B in central precocious puberty (CPP) and premature thelarche (PT).Methods: The girls who presented with breast development (between 5 and 8 years) were included in the study. All cases underwent bone age (BA) assesment. Basal serum FSH, LH...

Background: Impairment of the chromatin remodeling factors ATRX and DAXX and telomeres abnormality play a role in cancer biology, influencing the clinical outcomes. However, their roles in adrenal tumorigenesis require broader investigation.Aim: To evaluate ATRX and DAXX genotype and expression, telomere length, and the alternative lengthening of telomeres (ALT), as well as their clinical significance, in primary adrenoc...

The Influences of Circulating Leptin, Kisspeptin, and Neurokinin B Levels to Precocious Puberty in Obese Girls

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

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...

Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...

Copy Number Variants in Patients with Congenital Hypopituitarism Associated with Complex Phenotypes

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Elkina Stanimira , Blajeva Svetla , Halvadzhiyan Irina , Botzova Venetziya , Petrova Chayka

Although type 1 diabetes (T1D) is most common autoimmune chronic metabolic disease in childhood, data about the role of T-Lymphocytes (T-Ly) and B-Lymphocytes (B-Ly) in children after the diabetes onset are still controversial. The aim of the study was to evaluate the serum levels of T– and B-Ly in children with T1D as a predisposing factor for genital candidiasis (GC).Material: We studied 71 children with T1D at the age of 6 to 18 years, divided in...
