Evaluation of Primary Hypertriglyceridemia Patients: Ethiology, Phenotype, Treatment

Kaplan Emel Hatun Aytaç , Kumru Burcu , Albayrak Hatice Mutlu , Keskin Mehmet , Karaoglan Murat

Introduction: Plasma triglyceride (TG) is formed by an exogenous pathway taken from food and by an endogenous pathway produced from the liver. Primer hypertriglyceridemia occurs by genetic reasons. Higher TG levels occurs in lipoprotein lipase (LPL), ApoC2, ApoA5 gene defects. Secondary hypertriglyceridemia is caused by obesity, insulin resistance, alcohol and some drugs. In that study, we evaluated 10 patients with primer hypertriglyceridemia regards to clini...

Novel CYP17A1 Mutation and CYP21 Mutations in Two Siblings

Işık Emregul , Keskin Mehmet , Yeşilyurt Ahmet

Background: 17 hydroxylase deficiency is a rare form of congenital adrenal hyperplasia resulting from loss-of-function mutations involving the CYP17 gene. It is characterized by decreased production of glucocorticoids and sex steroids and increased synthesis of mineralocorticoid precursors.Objective and hypotheses: We aimed to identify genetic cause of lack of puberty in a girl and the cause of ambiguous genitalia in her sibling. Fourteen-year-o...

Is Type 1 Diabetes Mellitus Predictable? Investigation of Predictive Markers n Siblings of Probands with Newly Diagnosed Type 1 Diabetes Mellitus

Albayrak Serpil , Karaoglan Murat , Yıldırım Ahmet , Keskin Mehmet ,

Background/Aim: Type 1 diabetes Mellitus (T1DM) often presents with clear clinical signs after a long-term asymptomatic autoimmune process. This long and silent period has been leading to an increase in awareness day by day in order to prevent and predict the development of the disease. Among the well-known genetic and environmental risk factors, close relatives of the index cases constitute a population that is quite suitable for predicting and preventing the...

Evaluation of The Relationship Between the Immune and Endocrine System in Children Diagnosed with Polycystic Ovary Syndrome

Uygur Balık Ahmet , Keskin Mehmet , Karaoglan Murat , Keskin Ozlem , Yıldırım Ahmet , Albayrak Serpil

Polycystic ovary syndrome is the most common endocrinological disease in women of reproductive age. Although it is thought that pathologies such as insulin resistance, chronic low-level inflammation and hyperandrogenism are central theme of the disease, the exact pathophysiology of the disease has not been fully understood. This study’s aim is to reveal the relationship between routine endocrinological and immunological markers related to chronic inflammation, and to inv...

A Very Rare Thyroid Hormone Resistance Case Having Heterozygous Mutation in THRB Genes

Keskin Mehmet , Yılmaz Seniha Kiremitci , Kaplan Emel Hatun Aytac , Karaoğlan Murat , Karaer Kadri , Keskin Ozlem

Objective: Thyroid hormone resistance is a rare autosomal dominant disease. In the pathogenesis of this disease mutations have been reported in two types of thyroid hormone receptors, called alpha and beta. Deletions or mutations in cofactors required to demonstrate receptor effect also reported in the beta receptor gene. The symptoms vary according to the cases. Here; a case of thyroid hormone resistance which is noticed by chance and not treated is presented.<p class="ab...

Lipoid Adrenal Hyperplasia Diagnosed with Severe Cholestasis in Newborn

Kaplan Emel Hatun Aytac , Melekoğlu Nuriye Aslı , Keskin Mehmet , Cağatay Derya , Karaer Kadri

Introduction: Congenital lipoid adrenal hyperplasia is the most severe form of congenital adrenal hyperplasia and is rarely seen. Steroid synthesis cannot be done in the adrenal gonads. Adrenal glands have hyperplasia and lipid accumulation. Male babies are born to girls. Most of the cases are lost with severe adrenal insufficiency. Patients diagnosed and treated at supraphysiological doses during neonatal period. Here we present a case of lipoid adrenal hyperplasia diagnosed ...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...
