Boyadzhiev Veselin , Yordanova Nikolinka , Bazdarska Yuliya

We present a 10 years old boy, born from normal pregnancy, weght 3300 gr, lenght 51 cm. Normal motor and intellectual development. Family history for short stature - mother's height 150.3 cm (P2), target height 174.3 cm (P37). At 7 years of age the patient's height was 108.9 cm (- 2.4 SD) - below the target range. Bone age was delayed with more than -2 SD. Two stimulation tests for growth hormone (GH) assessment have been performed (with insulin and glucagon) –...

Evaluation of the first year of growth hormone treatment in Prader-Willi Syndrome Patients followed at an Expert Center of Rare Endocrine Diseases

Yordanova Nikolinka , Bazdarska Yuliya , Shishkov Savi , Halvadzhiyan Irina , Galcheva Sonya , Iotova Violeta

Introduction: Prader-Willi syndrome (PWS) is a rare imprinting disorder with evidence of increasing incidence. Treatment with recombinant human growth hormone (rhGH) has been shown to improve growth, body composition and final height. It is officially approved by the US Food and Drug Administration since 2000, but still not official indication in many countries.Aim: The aim of the current study is to assess the results o...

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...

Incidence of ALS deficiency in patients with growth hormone deficiency at tertiary pediatric endocrinology center

Rankova Kamelia , Iotova Violeta , Bocheva Yana , Shefket Sevim , Yordanova Nikolinka , Bazdarska Yuliya , Tsochev Kaloyan , Galcheva Sonya , Boyadzhiev Veselin ,

Acid-labile subunit (ALS) is a glycoprotein, which is produced in the liver in response to growth hormone (GH). The main role of ALS is to form a complex with insulin-like growth factor I (IGF-I) and IGF binding protein-3 (IGFBP-3) in order to extend their circulating half-life and thus support the action of GH. Although the mechanism and the consequences of ALS deficiency are well studied, ALS-deficient patients are still of research interest because of the unclear incidence ...
