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...

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 ...

Circulating C1q Complement/TNF-Related Protein (CTRP)-13 Levels in Obese Children and Its Relationship with Metabolic Disorders

Mert Erbaş Ibrahim , Paketci Ahu , Turan Serkan , Şişman Ali Rıza , Demir Korcan , Bober Ece , Abacı Ayhan ,

Background: C1q/tumor necrosis factor-related proteins (CTRPs) are the recently recognized members of the adipokine family, secreted from adipose tissue. Some types of CTRPs, including CTRP-13, play an important role in energy metabolism in humans. Also, CTRP-13 was found as an anorexigenic factor in experimental studies.Objective: We aimed to investigate serum CTRP-13 levels in obese and healthy children, as well as the...

Initial Neutrophil/Lymphocyte and Lymphocyte/Monocyte Ratios Can Predict Future Insulin Need in Newly Diagnosed Type 1 Diabetes Mellitus

Erbaş Ibrahim Mert , Hajikhanova Aygun , Besci Ozge , Acinikli Kubra Yuksek , Demir Korcan , Bober Ece , Abacı Ayhan ,

Background: The exact mechanism of the partial clinical remission in type 1 diabetes mellitus (T1DM) has not been elucidated yet. The severity of the inflammation at the time of diagnosis may have an impact on the occurrence or duration of this phase.Objective: We aimed to investigate the relationship between hematological inflammatory parameters at the time of diagnosis in children and adolescents with T1DM and the need...

Bone Density, HIV Infection and Antiretroviral Treatment: A 10-Year Follow-Up in Young Patients

Mora Stefano , Maruca Katia , Ambrosi Alessandro , Puzzovio Maria , Erba Paola , Nannini Pilar , Benincaso Annarita , Capelli Silvia , Giacomet Vania

Background: The success of highly active antiretroviral therapy (HAART) has dramatically increased life expectancy for human immunodeficiency virus (HIV)-positive patients, revealing a range of chronic problems associated with HIV. Among others, low bone mineral density (BMD) has been described in HIV-infected youths. Little is currently known about the changes of BMD over time in these patients.Objective and hypotheses: The aim of the study was to asses...

Serum Sex Hormone Binding Globulin Levels, But Not 4-Hour Profile of 17-Oh Progesterone, Would Be Useful in Monitoring Children with Congenital Adrenal Hyperplasia

Besci Ozge , Erbas Ibrahim Mert , Kume Tuncay , Acinikli Kubra Yuksek , Abacı Ayhan , Bober Ece , Demir Korcan ,

Background: There exists no gold standard for adjustment of treatment in congenital adrenal hyperplasia. Clinicians try to avoid over-and undertreatment by considering various indicators. We aimed to investigate the sampling times of 17-hydroxyprogesterone (17-OHP) and the use of sex hormone-binding globulin (SHBG) as a monitoring parameter, the association of which was not studied with clinical features. Materials and Methods: This cross-sectional study inclu...

Clinical course of primary empty sella in children: a 10-year single-center experience

Besci Ozge , Yasar Elif , Mert Erbas Ibrahim , Yuksek Acinikli Kubra , Demir Korcan , Bober Ece , Abacı Ayhan ,

Background: Various studies, mostly conducted in adults, evaluated the hormonal axis in primary empty sella (PES), and reported different forms of pituitary deficiencies. We report our 10-year experience of pediatric cases with PES, investigating the pituitary function, associated impairments, and responses to treatments.Materials and Methods: We reviewed 10,560 cranial and 325 pituitary magnetic resonance imagings (MRIs) performed in ou...

Influencing Factors on Selection of Initial Treatment Dose in Children Diagnosed with Isolated Growth Hormone Deficiency

Mert Erbaş İbrahim , Uyar Nilüfer , Nalbantoğlu Özlem , Özkan Behzat

Background: Although it has been recommended to start treatment in the range of 22-35 µg/kg/day in growth hormone (GH) deficiency, individualized dose selection is more preferred for those patients instead of a fixed dose. However, there is no consensus as to which dose should be started for which patient. In this study, we aimed to reveal the factors that affect the clinicians' preferences in the selection of the starting dose of GH treatment.<...

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...

Introduction: The etiology of hyperandrogenism is diverse and diagnosis is based on history, clinical findings, reliable measurement of steroid hormones and genetic analyzes. In the electrochemiluminescence immunoassay (ECLIA) method, the presence of various endogenous compounds and the use of certain pharmaceutical agents may cause interference in results, on the other hand liquid chromatography-mass spectrometry (LC-MS/MS) method allows measurement of 17 adr...
