Objective: The incidence of congenital hypothyroidism (CH) has increased worldwide. Lowering cut-off in screening programs has led to an increase in the rate of transient CH. We aimed to evaluate the rates of permanent and transient CH in cases referred from the screening program and to investigate the clinical and laboratory factors to predict the transient CH.Methods: 109 cases referred from the screening program to ou...

Background: X-linked hypophosphatemia (XLH) are rare inheritable disorders caused by excessive renal phosphate wasting manifesting as rickets in children and osteomalacia in adults. Osteoid accumulates due to the reduced mineralization rate. Based on previous histomorphometric bone biopsy studies it the impression that XLH is a low bone turnover disease. Very little is known about the level of bone markers in XLH and the effects of conventional medical treatment with oral phos...

Introduction: Packed red blood cell (PRBC) transfusions are an essential component of leukemia treatment regimens. Transfusion-induced iron overload can be seen after approximately 10 to 20 transfusions. Very little is known about transfusion-related iron burden in oncology populations and its possible effect on endocrine function and glycemia.Patients and methods: We evaluated growth parameters and endocrine disorders in relation to the iron overload st...

Background: Primary Addison’s disease (AD) is a rare endocrine condition, with reduced or absent secretion of adrenal hormones. Steroid replacement therapy normalizes endocrine assess and the quality of life. More than a half of patients display additional autoimmune conditions, which represent a considerable clinical concern.Objective and hypotheses: Antiparietal cells antibodies (APC-Ab) are commonly found in patients with autoimmune Addison’...

Background: The overall incidence of Cushing’s syndrome in children is ~0.2–0.5 new cases per million people per year. Cushing’s disease is more infrequent under 7-year-old children. The typical symptoms are not often observed in childhood. Therefore, the early diagnosis is difficult, when pituitary tumour is not detected by pituitary MRI.Objective and hypotheses: A 5-year-old boy was referred to our hospital by a decrease in growth veloci...

Introduction: Congenital hypothyroidism (CH) is classified as permanent CH (PCH) if levothyroxine (LT4) is life-long required, or as transient CH (TCH) if after LT4 discontinuation thyroid function remains normal. Early detection of TCH allows early discontinuation of LT4.Purposes: To identify predictors of TCH and PCH, and their cut-off value.Subjects and Methods: Retrospective st...

Objectives: Hypophosphatasia (HP) is a rare inherited disorder characterized by defective bone and teeth mineralization, and deficiency of serum and bone alkaline phosphatase activity. The symptoms are highly variable in their clinical expression, which ranges from stillbirth without a mineralized bone to early loss of teeth without bone symptoms. We aimed to report a patient with HP presenting with fibrous dysplasia.Methods:</st...

Background: GH response is influenced by genetic polymorphisms, including the rs1024531 polymorphism (A/G) in the promoter region of GRB10, a negative regulator of signaling through the IGF1 receptor. Allele A is associated with borderline lower baseline IGF1 SDS and 1.5-fold higher response to GH compared to allele G in children with GHD (P=0.0006).Objective: To test functional impact of the rs1024531 polymorphism in an in vitro</e...

Background: Screening for congenital hypothyroidism (CH) with the possibility of an early treatment has transformed the outlook for children with CH. Despite the unquestioned public health success of newborn screening programs, the management of CH is still controversial. Most patients with positive screening have permanent hypothyroidism but some of them may have transient hyperthyreotropinemia, so it is important to identify these patients in order to avoid lifelong unnecess...

Background: Response to GH treatment has been associated with single nucleotide polymorphisms (SNPs) within the promoter region of growth-related genes including GRB10 (rs1024531 (A/G, allele A increased response)), IGFBP3 (rs3110697 (G/A, G increased response)), CYP19A1 (rs10459592 (T/C, T increased response)) and SOS1 (rs2888586 (G/C, C increased response)). SOS1 is a positive regulator of GH signalling (MAPK pathway); the aromatase CYP19A1 promotes oestrogen synthesis to im...
