Mutations in HNF1A gene underlie the development of maturity onset diabetes of the young type 3 (MODY3). Mutations in ABCC8 gene are the cause of neonatal DM and the rare MODY12, which is clinically similar to MODY3. In these forms of MODY, there is a high sensitivity to sulfonylurea. Patient A, 17 y.o. He was born to woman with gestational DM. At the age of 12.5, fasting hyperglycemia of 13 mmol/l was detected. Insulin therapy was not prescribed due to the parent’s refu...

Background and aim: Prader-Willi Syndrome (PWS) is a rare disease with various clinical signs in different age periods. Early diagnosis has a proven benefit in PWS, allows for timely diet therapy and prevention of obesity, early administration of growth hormone. The purpose of the study is to analyze the features of neonatal adaptation in children with PWS, to evaluate the diagnostic efficacy in the dynamics of the analyzed period.<stron...

Introduction: Pseudohypoaldosteronism (PHA) is a clinical syndrome characterized by multiorgan or isolated renal tubular resistance to the effects of aldosterone, resulting in hyperkalemia, metabolic acidosis, and normal to high serum aldosterone levels. PHA may be primary (hereditary) or secondary (acquired). Primary forms are subclassified into two: PHA type 1 (salt-wasting) and PHA type 2 (salt-retaining). Secondary forms are typically associated with sever...

Background: Practicing as a Pediatric Endocrinologist in Armenia means living in a middle- to low-income country with semi-closed borders associated with war and conflicts. There are therefore fewer opportunities to attend educational events or training at highly rated hospitals worldwide to improve knowledge and skills on pediatric endocrinology. In April 2023 the Endocrine Society of Pediatric Endocrinologists (ESPE) held the ESPE Caucasus & Central Asia...

Background: Steroid 21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia. Patients present with cortisol and aldosterone deficiency as well as with hyperandrogenism, leading to virilisation in females and early adrenarche in both sexes. Requiring life-long glucocorticoid (GC) replacement, patients frequently experience daily fluctuations between GC overexposure and deficiency. Increased prevalence of metabolic disease con...

Background: Type 1 diabetes mellitus (T1DM) is an autoimmune disorder, which occurs mostly among children and adolescents. Armenia is a middle-low income country, where pediatric diabetic care is given centralized in three main centers. The 85-90% of diabetic children and adolescents are followed in the university hospital. During Covid-19 pandemic Armenia was under either lockdown or strict restrictions. The purpose of the current study is to assess the dynam...

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...

Introduction: Premature ovarian failure (POF) is defined as a heterogeneous disease leading to amenorrhea and ovarian failure before the age of 40 years. It is found in 1-3% of women of reproductive age, with some negative consequences such as cardiovascular disease, osteoporosis and sexual dysfunction. Triple X syndrome is characterized by POF with primary or secondary amenorrhea, tall stature, large feet. Girls with triple X syndrome show accelerated growth ...

Background: Growth hormone deficiency in conjunction with the function loss of other anterior pituitary hormones is called combined pituitary hormone deficiency (CPHD). The most common congenital CPHD is caused by mutations in genes: PROP1, POU1F1, HESX1, LHX3, LHX4, OTX2, GLI2, and SOX3. POU1F1 mutations are extremely rare among the Indo-European ethnic type (1% of all cases of congenital hypopituitarism) and more common among the Turkic peoples (7.3%...

Introduction: Orthodenticle homeobox 2 (OTX2) is a transcription factor that plays a critical role in brain and eye development. Heterozygous deleterious mutations in this gene lead to eye malformation such as anophthalmia, microphthalmia, coloboma or optic nerve hypoplasia, normal or hypoplastic pituitary gland and normal or ectopic posterior pituitary gland with isolated growth hormone deficiency or combined pituitary hormone deficiency. There is no...
