Leri-Weill Syndrome Phenotype with Atypical Cytogenetic Finding

Mladenov Vilhelm , Iotova Violeta , Angelova Lydmila , Stoyanova Milena , Bogdanova Viktoria

Introduction: Leri-Weill dyschondrosteosis (LWD) is caused by haploinsufficiency of the SHOX gene, located in the pseudoautosomal region (PAR 1) of the short arm of the X and Y chromosomes. The gene is expressed in highest levels in bone tissue and its product likely controls the chondrocyte apoptosis. Deletions and duplications are most frequent, point mutations are responsible for minority of the cases. The main clinical symptoms of LWD include disproportionate short stature...

Prader-Willi Patient with Rectal Bleeding – Experience in Center for Rare Endocrine Disordesrs in Varna, Bulagria

Yordanova Nikolinka , Iotova Violeta , Galcheva Sonya , Bazdarska Yuliya , Mladenov Vilhelm , Boyadzhiev Veselin

Prader-Willi syndrome (PWS) is a genetic condition (frequency from 1:8000 up to 1:30 000), which is associated with deletions of chromosome 15 (region 15q11.2), maternal uniparental disomy and impring defects. It is characterized by muscle hypotonia in the early postnatal period, excessive weight gain after 2 years of age, lack of satiety, short stature, hypogonadism and compulsive-like behavior. Every patient has his/her own specific needs that change with age and individuali...

46,XY Complete Gonadal Dysgenesis with Late Diagnosis

Mladenov Vilhelm , Andonova Silvia , Savov Alexey , Hachmeriyan Mari , Popova Ralitza , Iotova Violeta

Background: 46,XY Complete Gonadal Dysgenesis (Swyer Syndrome) is a rare cause for DSD with incidence ≈1:80000. It is characterised by defective formation of the gonads as a result of structural anomalies in the sex chromosomes or mutations in specific genes. In 20% of the patients deletion/mutation in SRY can be found. Mutations, deletions or duplications in other genes (NRD5A1, DHH, DAX1, WNT4, DMRT, etc.) are also reported. The phenotype is completely female and the d...

Clinical and metabolic characteristics of hyperandrogenic girls with non-classic congenital adrenal hyperplasia and polycystic ovary syndrome

Karamfilova Teodora , Galcheva Sonya , Mladenov Vilhelm , Boyadzhiev Veselin , Bazdarska Yuliya , Yordanova Nikolinka , Iotova Violeta ,

Background: Non-classic congenital adrenal hyperplasia (NCCAH) and polycystic ovary syndrome (PCOS) present with similar hyperandrogenic symptoms in adolescent girls and may be associated with the development of cardiometabolic disorders.Aim: The purpose of the study was to evaluate the prevalence and the association between the clinical and biochemical parameters of hyperandrogenism and metabolic disorders in girls with...

Comparison between clinical, metabolic and hormonal parameters in adolescent girls with hyperandrogenism and healthy controls

Mladenov Vilhelm , Galcheva Sonya , Karamfilova Teodora , Bocheva Yana , Ivanova Darina , Iotova Violeta

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...

Results from the Implementation of a 2 Year Growth Awareness and Growth Disorders Screening Campaign (GrowInform)

Tsochev Kaloyan , Stoycheva Rosica , Iotova Violeta , Karamfilova Teodora , Markovska Velina , Halvadjian Irina , Galcheva Sonya , Mladenov Vilhelm , Boyadzhiev Veselin , Ivanova Antoaneta

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: Evidence associates obesity with glomerular hyperperfusion. Concurrent inflammation, hypertension, dyslipidemia, and insulin resistance represent further established risks to renal health in both children and adults.Objective and hypotheses: To investigate the relationship between childhood obesity and risk of renal impairment.Method: A total of 114 (38.6% boys) obese according to the IOTF reference but otherwise health...

Background: Continuous glucose monitoring (CGM) correlates with optimal control in both children and adults with type 1 diabetes (T1D) regardless of type of treatment. CGM plays a major role in decreasing the time spent in hypoglycemia and hyperglycemia, and achieving better quality of life.Aim: To evaluate the usage and benefits of out-patient CGM and assess parents’ attitudes to it at a non-reimbursed setting.Methods: A tota...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...
