In 2014 Varna Pediatric Endocrine Society started a program for timely diagnosis and treatment of stature deviations. GPs with 23 058 children under their care were trained and provided with a specialized auxological software to warn them for every stature deviation. From the expected 692 children with short stature (3% of the total), only 33 (0.14%) were sent for further evaluation. Due to the unsatisfactory results we decided to organise a new campaign with the help of media...

Aim: Evaluation of the results from the campaign GrowInform (2017-2019), a project with the main aim to raise awareness of growth disorders, and secondary aims to facilitate screening for growth deviations in children from areas with no easy access to pediatric endocrinologists, thus achieving earlier diagnosis and treatment.Methods: For 2 years (April 2017 to March 2018), GrowInform acted in 13 cities and towns from Eas...

Background: The most common forms of maturity-onset diabetes of the young (MODY) are MODY-GCK and MODY-HNF1A. Prevalence of MODY in Russian population is unknown.Aims and objectives: To compare clinical laboratory characteristics of MODY-GCK and MODY-HNF1a in children and adolescents, to estimate prevalence of MODY.Method: 151 children and adolescents were screened for mutations in GCK and HNF1A. HbA1c, fasting and stimulated gluco...

Background: MODY is monogenic. About 1% of diabetes has a monogenic cause but is frequently misdiagnosed as DM1 or DM2.Objective and hypotheses: It is important to study family history of patients with atypical diabetes forms for verification of diagnosis and prognosis.Method: Genetic, biochemical and hormonal testing, 2 patients were examined.Results: At pre-school medical examination a general practitioner ...

Background: Hypoparathyroidism, sensorineural deafness, and renal disease (HDR syndrome, Barakat syndrome) is a rare condition, caused by a mutation on chromosome 10p which affects the GATA3 gene. GATA3 encodes a transcription factor important for the embryonic development of the parathyroid gland, the auditory stem, and the kidneys. Its expression has also been found in the thymus and the central nervous system. A wide range of renal involvement has been rep...

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...

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...

Background: Non-classic congenital adrenal hyperplasia (NCCAH) is a genetic disorder characterized by hyperandrogenism associated with potential metabolic alterations and changes in body composition and bone mineral parameters.Aim: The purpose of this pilot study was to evaluate the clinical and biochemical characteristics in association with bone mineral parameters and body composition in female patients diagnosed with ...

Background: Diabetes mellitus (DM) is one of ‘minor’ components of autoimmune polyglandular syndrome type 1 (APS1). The prevalence of DM in APS1 varies from 2.5 to 18% in different populations.Objective and hypotheses: To study disease phenotype and genotype of APS1 patients with DM.Method: All patients diagnosed with DM were selected from the Russian registry of APS1 patients. Clinical data, AIRE-gene mutations and immun...

Background: Polycystic ovary syndrome (PCOS) and non-classical congenital adrenal hyperplasia (NCCAH) are the most common hyperandrogenic disorders in adolescent girls. Though their etiology and pathogenesis differ, there is a significant overlap between physiological, clinical and hormonal findings and physiological phenomena. Adult patients with PCOS have increased prevalence of obesity, metabolic disturbances, increased cardiovascular risk, risk of impaired...
