Immunogenicity of recombinant growth hormone therapy in the children with short stature and consequences on growth-promoting effect

Karaoglan Murat , Isbilen Elif , Keskin Mehmet ,

Background/Aim: Although there are many well-known components that affect the growth response to recombinant growth hormone (rGH), its effect on total height gain is still not fully predictable. A limited number of studies have been reported revealing up-to-date data on the relationship between immunogenicity and growth-promoting effects of rGH. The study aimed to examine the antibody formation against rGH and its consequences on growth-promoting effect in chi...

The Results of CYP21A2 Mutation Analysis in Adolescent with Polycystic Ovary Syndrome

Yagli Colakoglu Elif , Bulus Derya , Andiran Nesibe , Ufuk Isin Ugur

Background: Diagnosis of polycystic ovary syndrome (PCOS) in the adolescent is difficult due to high background rate of menstrual irregularity, high prevalence of polycystic morphology and hyper and rogenic features in this population. Also late onset congenital adrenal hyperplasia (LOCAH) mimics PCOS in this period. It is important to distinguish these entities because of the differences in their therapy. The study aimed to find out the frequency of LOCAH in patients who diag...

The V89L Polymorphism in the SRD5A2 Gene in Cases with Undescended Testis

Yesilada Elif , Akinci Aysehan , Gulbay Gonca , Yuksel Sengul , Savaci Serap

Background: Steroid 5α-reductase catalyzes the conversion of testosterone into the more active androgen, dihydrotestosterone (DHT). In 46, XY patients with recessive mutations in steroid 5α-reductase type 2 enzyme (SRD5A2) gene, the degree of ambiguity ranges from isolated hypospadias to severe undermasculinization. SRD5A2 gene is located on chromosome 2 (p23 region) and is comprised of five exons and four introns.Objective and hypotheses: Mult...

Two Different Diagnosis of Pseudohypoaldosteronism

Bulus Derya , Andiran Nesibe , Colakoglu Elif Yagli , Altuntas Nilgun

Background: Pseudohypoaldosteronism (PHA) is a disorder caused by aldosterone resistance with impaired sodium reabsorption and potassium excretion from the body. PHA is subdivided into primary (genetic) and secondary (transient) forms. Primary PHA is caused by mutations in genes encoding epithelial sodium channel or mineralocorticoid receptors. The secondary PHA may occur due to urinary tract malformations, urinary tract infections (UTI), drugs, etc. We present here two cases ...

Is vitamin D Important Player in Hepatosteatosis in Childhood Obesity?

Ozsu Elif , Topcu Feyza Nur , Tepe Derya Acar

Background and aim: Childhood obesity is one of the most serious public health problem. Obesity-related complications such as hepatic steatosis or type 2 diabetes can now be monitored even during early childhood. The aim of the study was to examine the relationship between vitamin D levels and obesity with hepatosteatosis (HS) in children.Methods: A total of 128 children with obesity were included in this study. HS was diagnosed using ultrasonography. HS...

Prediction of Adult Height Based on Automated Bone Age Estimation in Early Puberty: A Single-Center Prospective Study

Huseyin Yigit Murat , Yesiltepe Mutlu Gul , Eviz Elif , Hatun Sukru

Introduction: In cases of precocious puberty, an important factor in making treatment decisions is when adult height estimates based on bone age (BA) determination are behind midparental height. In Turkey, clinicians often use the Greulich Pyle (GP) atlas to determine BA, which can lead to significant differences between assessors. The aim of this study was to compare estimated adult height (EAH) calculations based on BA determined by the automated BoneXpert m...

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Backround: Cases diagnosed with congenital hypothyroidism are considered to be at risk of thyroid nodule formation and subsequent thyroid carcinoma due to TSH overstimulation. Few cases has been reported hitherto. We are presenting two siblings diagnosed with congenital hypothyroidism due to dyshormogenesis who developed thyroid papillary carcinoma during follow up.Case presentation: Case 1 was born at term as the first ...

Metabolically Unhealthy Obese Children and Adolescents Have Higher Bone Mineral Density Than Normal Weighted Controls but Lower than Metabolically Healthy Obeses: No Effect of FGF21 Levels

Akduman Filiz , Siklar Zeynep , Ozsu Elif , Doğan Ozlem , Kir Metin , Berberoglu Merih

Introduction: The harmfull or benefical effect of obesity on bone mineral density (BMD) is remain controversial in children and adolescence. Either increase or decrease of BMD have been reported. Several factors such as insülin resistance, prediabetes, high proportion of fat mass, sedentary lifestyle were suggested to cause the differences of BMD in obesity. FGF-21 is a metabolic factor that plays a specific role in the regulation of carbohydrate and lipi...
