Does Socioeconomic Status Play a Role in Paediatric Insulin Pump Access? A Systematic Review

Nahum Andrea , Alexandrou Demitra

*Both authors contributed equally to this workBackground: Continuous Subcutaneous Insulin Infusions (CSII) or insulin pumps improve overall glycaemic control in paediatric populations. Children’s access to CSII may partly depend on socioeconomic status (SES), healthcare systems, and funding structures.Aim: The aim of our systematic review was to evaluate whether SES affects children’s a...

A rare heterozygous IGFI variant causing impaired IGF-I cleavage and postnatal growth failure: a novel disease mechanism with insights into IGF-I physiology

Cottrell Emily , Andrews Afiya , Williams Jack , Chatterjee Sumana , Edate Sujata , A. Metherell Louise , Hwa Vivian , L. Storr Helen

Background: Pathogenic IGFI gene mutations causing childhood growth failure are rare. Only 5 autosomal recessive mutations, one IGFI copy number variant and 2 heterozygous frameshift mutations are reported. Heterozygous missense IGFI mutations have not previously been described.Objectives: To identify and functionally characterise a novel missense IGFI variant in a patient with postnat...

Novel dominant negative GH receptor variants provide important insights into GH receptor physiology

Andrews Afiya , Cottrell Emily , Maharaj Avinaash , Ladha Tasneem , Williams Jack , Metherell Louise A , McCormick Peter J , Storr Helen L ,

Background: Growth hormone insensitivity (GHI) encompasses normal/elevated growth hormone (GH), low IGF-I levels and growth restriction. Non-classical/mild-moderate GHI is an emerging entity which is poorly characterised, and, in many subjects, the underlying cause is unclear. Heterozygous dominant negative (DN) variants located in the intracellular/transmembrane domain of the GH receptor (GHR) cause a ‘non-classical’ GHI phenotype.<p class="abst...

High carrier frequency of a nonsense p.W230X variant in HSD3B2 gene among Ossetians

Makretskaya , Kalinchenko Natalia , Tebieva Inna , Ionova Sofya , Marakhonov Andrey , Tiulpakov Anatoly , Zinchenko Nina Rena

Background: Congenital adrenal hyperplasia (CAH) caused by 3ß-HSD deficiency is a rare form of congenital adrenal deficiency with an autosomal recessive type of inheritance. We have previously demonstrated that a single nucleotide variant NM_000198.3:c.690G>A (P.W230X) in the homozygous state is a frequent cause of CAH among the indigenous population of North Ossetia-Alania represented by Ossetians.Aims: To stud...

Survival, Endocrine Disorders and Quality of Life in 135 Children with Craniopharyngioma After Surgical or Combined Treatment

Mazerkina Nadia , Savateev Alexandre , Gorelyshev Sergey , Trunin Yuri , Golanov Andrey , Kutin Maxim , Kalinin Pavel , Konovalov Alexandre

Patients and Methods: We analyzed 135 primary operated craniopharyngioma (CP) patients and 75 CP patients, received radiotherapy/radiosurgery in 2005-2012. Neurologic, endocrine, visual functions, quality of life (QofL) and neuroimaging data before and after treatment were assessed.Patients were divided in 2 groups according to CP location: 48,5% endosellar (ESCP), and 51,5% suprasellar (SSCP). Surgical treatment included tumor e...

Genotype–Phenotype Correlations in Bulgarian Patients with c.293-13A/C>G Splice Mutation of 21CYPA2 Picked up by Neonatal Screening (NS)

Stoeva Iva , Dineva Ganka , Kirov Andrey , Kostova Antoaneta , Todorov Tihomir , Aroyo Ani , Todorova Albena , Mitev Vanio

Background: Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders caused by defects in one of the several adrenal steroidogenic enzymes. 80–95% of CAH are due to mutations in CYP21A2 gene encoding 21 hydroxylase. Its residual activity defines the clinical form. Except deletions and large gene conversions, nine pseudogene-derived mutations are responsible for 95% of all CAH alleles. The mutational distribution varies between diffe...

Cyp21a2 Mutation Spectrum in Bulgarian Cah Patients

Todorova Albena , Kirov Andrey , Stoeva Iva , Todorov Tihomir , Dineva Ganka , Kostova Antoaneta , Aroyo Ani , Mitev Vanio

Background: Congenital adrenal hyperplasia (CAH) is a group of inborn errors of steroidogenesis. It is mainly caused by steroid 21-hydroxylase coding gene (CYP21A2) mutations. More than 30% of the CYP21A2 mutations are deletions, with ethnic specific differences. The Bulgarian mutational spectrum of CYP21A2 gene is unknown.Objective and hypotheses: To determine CYP21A2 mutation spectrum in Bulgarian CAH patients.<p...

Methodological Considerations into the Approach for Genetic Diagnostics of Congenital Adrenal Hyperplasia in a Girl with SW Form and Relatively Higher Needs of Mineral Corticoids

Dineva Ganka , Stoeva Iva , Kirov Andrey , Todorova Albena , Iliev Daniel , Kaleva Narcis , Grozdanova L

Background: 80–95% of congenital adrenal hyperplasia (CAH) cases are due to mutations in the CYP21A2 gene encoding 21 hydroxylase. The residual activity of the gene defines the clinical form. Routine mutational screening of CYP21A2 defects is shown to effectively support the complex diagnostic and treatment procedure of newborns with CAH.Objective: We aimed to characterise the phenotype of a girl with compound heterozygosity of ...
