Further analyses on the role of IGF-I in the diagnosis of GH deficiency (GHD) in children

Lussu Anna , Incandela Valeria , Guzzetti Chiara , Ibba Anastasia , Casula Letizia , Loche Sandro

Background: The diagnosis of GHD in children is based on auxological, biochemical, neuro-radiological, and genetic tests. Biochemical tests include evaluation of stimulated GH secretion and baseline IGF-1 determination. Although IGF-1 is the most reliable indicator of GH action, its value should always be interpreted in conjunction with other clinical and biochemical parameters. Since IGF-1 has good specificity (about 90%), but low sensitivity (about 70%), nor...

Frolova Elena , Kolodkina Anna , Zubkova Natalya , Sozaeva Leila , Usoltseva Olga , Tsvetkova Valeria , Anoushenko Anton

Background: APS type 1 is known to be associated with autoimmune gastroenterological pathology, which could be the very first and the worst-controlled manifestation of APS type 1. Treating these conditions in APS type 1 is debatable at present.Objective and hypotheses: We describe gastroenterological pathology in7 patients with APS type 1: clinical specifics, therapy, outcomes.Methods:</str...

Effects of seasonal variability of insolation and COVID-19 pandemic isolation on vitamin D concentrations in children

Smyczyńska Joanna , Hilczer Maciej , Łupińska Anna , Pawelak Natalia , Lewiński Andrzej , Stawerska Renata

Introduction: Vitamin D may be considered as a hormone of prohormone of pleiotropic effects. Seasonal variability of insolation affects its synthesis in humans. In our latitude, vitamin D deficiency is widespread. In 2018, updated recommendations for vitamin D supplementation were published in Poland by Rusi&nacute;ska et al. In 2020, SARS-CoV-2 pandemic lockdown was introduced, with suggestions of protective anti-viral vitamin D role.<p class="ab...

Kallmann syndrome as a manifestion of tubulinopathies - a boy with newly defined TUBB3 R262H syndrome.

Folga Barbara , Winczewska-Wiktor Anna , Smigiel Robert , Niedziela Marek , Kolesinska Zofia

Background: Microtubules, polar polymers of αβ-tubulin heterodimers, constitute dynamic cytoskeletal structures implicated in the regulation of axonal activity along with neuronal proliferation and migration. Tubulinopathies, caused by pathogenic variants in genes encoding different isotypes of tubulin, lead to a wide and overlapping range of nervous system malformations and neurodevelopmental disorders. Namely, heterozygous missense and nonsense mu...

Osteoporosis as the first sign of Cushing disease - a case report

Łupińska Anna , Stawerska Renata , Aszkiełowicz Sara , Kowalik Dorota , Lewiński Andrzej

We present the case of a 16.5-year-old short, thin boy with Cushing disease. The first symptom of the disease was spinal pain and vertebral fractures attributed to osteoporosis. The patient was admitted to the clinic due to severe back pain. On dual X-ray absorptiometry (DXA), the Z-score TBLH was: -1.9, Z-score Spine: -4.2. The X-ray and magnetic resonance imaging (MRI) revealed multilevel fractures of the thoracolumbar vertebrae. The causes of this condition initially remain...

Evaluation of the frequency of decreased bone mineral density and the impact of selected auxological and hormonal factors on bone mass among children with endocrine disorders

Stawerska Renata , Łupińska Anna , Aszkiełowicz Sara , Lewiński Andrzej

Introduction: Bone mineral density (BMD) is affected not only by genetic and enviromental causes, but various hormonal factors. It seems reasonable to seek for dependencies between BMD and paediatric endocrinopathies. The aim of the study was to assess the frequency of decreased BMD in children with several endocrinological disorders and evaluate the influence of selected auxological and hormonal parameters on their BMD.Materials...

Correlation between IGF-1 at diagnosis and adult height in children with short stature

Incandela Valeria , Lussu Anna , Guzzetti Chiara , Ibba Anastasia , Loche Sandro , Casula Letizia

Background: Insulin-like Growth Factor-1 (IGF-1) is an amino acid peptide produced under the effect of Growth Hormone (GH), mostly secreted by the liver, which stimulates bone growth. IGF-1 levels have high specificity and low sensitivity for the diagnosis of Growth Hormone Deficiency (GHD). Higher IGF-1 levels are classically associated with a better response to growth hormone therapy. The aim of this study was to investigate the correlation between serum IGF...

Improving detection of rare overgrowth syndromes referred to the endocrinology ward for analysis of acromegaly

van Essen Trui , Rosenberg Anna , de Herder Wouter , Jan van der Lelij Aart , de Graaff Laura

Background: In our center for adults with rare genetic syndromes, we see adolescents and young adults with overgrowth syndromes, among others. In our 'general endocrinology' outpatient clinic, we also see patients with overgrowth, but in these cases the overgrowth is due to excess of growth hormone (GH). Our clinical impression is that the differentiation between the two is often challenging. Therefore, we believe it is important to emphasize the dif...

Craniosynostosis in Patients With X-Linked Hypophosphatemia: a monocentric experience

Grandone Anna , Luongo Caterina , Aiello Francesca , Romano Francesca , Miraglia Del Giudice Emanuele , Aliberti Ferdinando

Introduction: X-linked hypophosphatemic rickets (XLHR) represents the most common form of genetic hypophosphatemia and causes rickets in children because of increased FGF23 secretion and renal phosphate wasting. Even though cranial vault an craniovertebral anomalies of potential neurosurgical interest, namely early closure of the cranial sutures and Chiari type I malformation (CM-I), have been observed in children with XLH, their actual incidence and character...

Relationship Between Placental PEG10 Methylation and Postnatal Weight Gain in 6 Year-Old Children

Introduction and objectives: Imprinted genes have been broadly related to prenatal growth regulation. PEG10 is a maternally imprinted gene involved in cellular proliferation that is mainly expressed in the placenta and in some adult tissues. In mice, mutations in this gene have been related to growth restriction of both the embryo and the placenta. Nevertheless, its role in postnatal growth has not yet been established. We aimed to study prospectively the rela...
