The Role of Midkin and Inflammatory Cytokines in The Pathophysiology of Metabolic Syndrome in Children and Adolescents with Classical Congenital Adrenal Hyperplasia Due to 21 Hydroxylase Enzyme Deficiency.

Çetinkaya Semra , Kesikli Burcu , Ayral Arıbal Pelin , Yazıhan Nuray

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase(21-OH) deficiency is the most common type of CAH. In the treatment, the insufficinet hormones are replaced. The excess doses cause hypercortisolism, insufficient doses; causes hyperandrogenism. Both metabolic conditions; It has been found to be associated with comorbidities that increase the risk of cardiovascular disease. Here, it is aimed to determine the comorbidities that increase the risk of cardiovascular disease...

Child with AR sitosterolemia with no hematological manifestations.

Alkhalaf Abeer , Aldubayee Mohammed , Alzaben Abdullah

Sitosterolemia is an autosomal recessive disorder affecting lipid metabolism which is characterized by decreased biliary excretion and increased absorption of plant sterols and cholesterol, leading to significantlyelevated serum levels of plant sterols. Approximately 80 homozygous or compound heterozygous variants in adenosine triphosphate-binding cassette subfamily G genes (ABCG5/ABCG8) genes have been described in patients with genetically confirmed sitosterolemia. Clinicall...

Interim analysis of the prospective evaluation of putatively influential factors associated with the timing and duration of honeymoon phase in newly diagnosed pediatric patients with Type 1 Diabetes

Özdemir Mustafa , Uçar Ahmet

Background: Type 1 Diabetes (T1D) is a chronic condition characterized by the autoimmune destruction of pancreatic beta cells, leading to insulin deficiency. The honeymoon phase (HP), a period of partial clinical remission shortly after the diagnosis, presents a significant opportunity for intervention. Understanding the factors influencing the duration and onset of HP could inform treatment strategies and potentially prolong the remission period.<p class=...

Premature ovarian failure in a tall adolescent

Dağdeviren Çakır Aydilek , Çetinçelik Ümran , Uçar Ahmet

Introduction: Primary ovarian failure (POF) is traditionally defined as cessation of menstruation prior to 40 yr of age and diagnosis is confirmed by elevated serum FSH levels (often above 40 IU/L). It is known that 0.1% of the population is affected with POF before age 30 yr. Here, we report a case with POF, who presented wit tall stature due to structural abnormalities in X chromosome.Case Report: A 13.5 year-old-adole...

Evaluation Of The Growth Hormone-Insulin like Growth Factor1 Axis And Serum Fibroblast Growth Factor 21 Levels As Related To Stature In Children And Adolescents With Coeliac Disease Adherent To Gluten Free Diet

Kaya Fırat , Urgancı Nafiye , Merve Usta Ayşe , Çelik Sedanur , Uçar Ahmet

Background: Coeliac disease(CD)is a common cause of stunted growth. Despite adherence to gluten-free diet(GFD), short stature may persist in some patients with CD. Studies investigating the growth hormone(GH)-insulin like growth factor-1(IGF1) axis in children and adolescents withCDare scant and inconclusive. Fibroblast growth factor-21(FGF-21)is a181amino acid polypeptide that plays a role in growth, lipid and glucose metabolism. The inhibitory effects of FGF...

A Case with Alstrom Syndrome with a Novel Pathogenic Variant In ALMS1 gene as a Rare Cause of Diabetes Mellitus

Dağdeviren Çakır Aydilek , Gizem Bolaç Özyılmaz Leyla , Uçar Ahmet

Introduction: Alstrom syndrome (ALMS) is an autosomal recessive disorder characterized by multiple organ involvement, including progressive cone-rod dystrophy, sensorineural hearing loss, childhood obesity, and type 2 diabetes mellitus. Pathogenic variants in the ALMS1 gene are the known cause for the occurrence of this devastating condition. Here, we reported a case of Alstrom syndrome with a novel homozygous variant in the ALMS gene, who presented to our cli...

A Rare Cause of Primary Ovarian Insufficiency: Novel Homozygous c.2120G>C(p.Arg707Pro) Pathogenic Variant in the MCM8 Gene

Eren Simge , Türkyılmaz Ayberk , Özdemir Mustafa , Uçar Ahmet

Introduction: Primary ovarian insufficiency (POI) is a condition characterized by amenorrhea with elevated FSH and LH levels as a result of ovarian dysfunction. Ovarian failure is a very rare condition in pediatric population. Genetic syndromes (Turner, Fragile X syndrome) or malignancy treatment are the main reasons. The minichromosome maintenance complex component 8 (MCM8) gene is responsible for the repair of DNA double-strand breaks;MCM8 is a rare cause of...

Evaluation of the Frequency and Time Course of Side Effects Asscociated With Metformin Use In Obese Adolescents As Related to Weight Loss: A Prospective Single-Centre Observational Study

Mısırlı Özdemir Ebru , Dağdeviren Çakır Aydilek , Bilge Özakçe Mehmet , Uçar Ahmet

Background: Metformin is a well-known biguanide approved for treatment of Type2 Diabetes. Metformin is not considered as an anti-obesity drug despite its common off-label use. Currently, there are no data regarding the profile of metformin related gastrointestinal side effects (MRGSE) in obese adolescents.Aim: To identify the frequency and time course of MRGSE in obese adolescents and assess the presence of any associati...

A Rare Cause of 46, XX ovotesticular DSD: Tetragametic Gonadal Chimerism

Uçar Ahmet , Güran Tülay , Eren Funda , Dokucu Ali Ihsan , Sahin Süleyman , Tanik Canan

Introduction: Virilization and hirsutism are clinical findings of androjen excess in females mostly due to polycystic ovary syndrome, although androgenic drugs, nonclassic congenital adrenal hyperplasia and androgen secreting adrenal/ovarian lesions are also implicated. 46, XX ovotesticular disorder of sex development (DSD) is the rarest form of DSD with an incidence of less than 1 in 20000.Case report: A 15-year-old ado...

Introduction: Androgen insensitivity syndrome (AIS) is a 46,XY difference of sex development (DSD) classically caused by mutations in the X-chromosomal androgen receptor (AR) gene. Nevertheless, in over 50% of individuals with clinical AIS no AR coding gene mutation can be found. We previously established an assay (apolipoprotein D (APOD) assay) that measures androgen dependent AR-activity in genital skin fibroblasts (GFs). Using this assay we identified a gro...
