Cardiac Autonomic Neuropathy is Highly Predictive for Survival in Children with Mauriac Syndrome

Arshinkova Margarita , Slavcheva Olga , Konstantinova Maia

Background: Diabetic autonomic neuropathy (DAN) is predictive for subsequent mortality mainly due to terminal renal insufficiency. DAN is screened by cardiac tests based on heart rate variability (HRV).Aim: To assess cardiac autonomic neuropathy (CAN) and its predictive value for survival in children with Mauriac syndrome.Material and methods: The study included 12 patients with Mauriac syndrome (growth retardation, hepatomegaly an...

Bone and mineral turnover in newly diagnosed children and adolescents with type 1 diabetes mellitus

Slavcheva-Prodanova Olga , Savova Radka , Archinkova Margarita , Konstantinova Maia

Introduction: There is still controversy about the levels of bone turnover markers at type 1 diabetes (T1D) onset and their dynamics at follow-up. Bonfanti et al. did not find any differences at onset, while few months afterwards beta cross laps level was significantly lower. Pater et al. found lower levels of osteocalcin and Log beta cross laps at onset which normalized after 3 and 12 months. Possible mechanisms are metabolic acidosis, decre...

Konstantinova Maia , Kozak Milos , Radev Radoslav , Pandova Rositza , Dimova Hristina , Georgiev Rumen

Introduction: The new technologies in diabetology improved not only HbA1c, but also ‘Time in range’, ‘Glycemic variability Index ‘/GVI/, and ‘Patient’s Glycemic Status’ /PGS/. Parents of children and patients with diabetes demonstrated impatience for artificial pancreas systems /APS/. They initially created ‘Nightscout’ platform for remote monitoring of the glucose sensors and then – Do It Youself Open Source Artificial Pancrea...

Dimitrova Mihaela , Stefanova Elisaveta , Glushkova Maria , Todorova Albena , Todorov Tihomir , Konstantiva Maia , Kazakova Krasimira , Tincheva Radka

Background: Precocious puberty is defined as the onset of pubertal signs in girls younger than 8 years of age and in boys younger than 9 years of age. Central precocious puberty is due to an early activation of the hypothalamic-pituitary-gonadal axis. Different candidate genes were involved in the etiology of the disease. To date, mutations in the maternally imprinted gene MKRN3 are most frequently found in families with CPP.Objective and hypotheses: The...

Favourable GH Treatment Response in a Young Boy with Achondroplasia

Krstevska-Konstantinova Marina , Slaveska Nevenka

Background: Achondroplasia is a skeletal dysplasia being the most common cause of rhizomelic dwarfism.Case presentation: We present a 10 years old boy who was first diagnosed prenatally. He had a mutation c1138G>A in the gene FGFR3 in a heterozygotic constellation. His IGF1 levels and IGFBP3 were normal. Two stimulation tests for GH were performed with normal levels of the hormone. His psychomotor development was adequate for his age except for speec...

Congenital Glucose–Galactose Malabsorption in a Male Infant

Slaveska Nevenka , Krstevska-Konstantinova Marina

Background: Congenital glucose–galactose malabsorbtion is a rare autosomal recessive disorder of intestinal transport of glucose and galactose. It is characterized by watery diarrhoea, dehydration, failure to thrive, or early death without appropriate dietary treatment.Case presentation: The patient was 15 days old when he was admitted to the hospital because of continued, severe, watery, acidic diarrhoea and hypernatremic dehydration. The abnormal ...

Severe Growth Retardation and Hypothyroidism due to Hashimoto’s Thyroidits

Krstevska-Konstantinova Marina , Stamatova Ana , Gucev Zoran

Background: Hashimoto’s thyroiditis is a common autoimmune disease in pubertal and adolescent girls. In the past years the incidence of this autoimmune disease of the thyroid gland has increased.Objective and hypotheses: We present a 12.5 year old girl who had her first visit at our Pediatric Endocrinology Department at the age of 10 years due to short stature and clinical signs of hypothyroidism. Her height was – 3SD SDS and her BMI was 12.7. ...

Infantile Hypophosphatasia

Slaveska Nevenka , Krstevska-Konstantinova Marina , Trajkovski Zoran

Background: Hypophosphatasia (HP) is a rare inherited disorder characterised by defective bone and teeth mineralization because of deficient serum and bone alkaline phosphatase activity due to mutations in the tissue-nonspecific ALP (TNALP) gene. Infantile HP (IHP) is one of the six recognized clinical forms according to age at presentation and clinical features. IHP is characterised by skeletal abnormalities due to demineralization and rachitic changes in the metaphyses, prem...
