Introduction: Secondary hyperparathyroidism is a serious and expected complication in almost every patient with chronic kidney disease (CKD). Nevertheless brown tumors formed by osteoclasts are rarely found in this subtype of patients and are extremely rare in children with CKD. The most common localizations of brown tumors are the jaw and long bones. We aimed to present three clinical cases of brown tumors in children with CKD on hemodialysis observed in a single dialysis cen...

Background: Chronic kidney disease (CDK) is one of the most common indications for treatment with recombinant human GH (rhGH).Objective and hypotheses: The aim of our study was to investigate the effect of rhGH therapy in pediatric patients with different stages of CKD.Method: 49 children (35 boys and 14 girls) aged from 0–18 years (mean age 9.01±4.28) with proven CKD and height retardation were treated with rhGH by a sin...

Background: Growth hormone deficiency (GHD) in children is a rare condition, which requires pathogenic therapy. In Russia GH treatment (GHT) is part of a federal program called “Seven high expenditure diseases” (7HED) and is fully state funded. In the rare cases when a GHD child cannot be treated with GH, financial and medical support for the child and its family is provided by the state. It is therefore important to understand the cost-effectiveness of GHT for child...

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: Autoimmune polyglandular syndrome type 1 (APS-1) is a rare disease associated with mutations in the autoimmune regulator (AIRE) gene and characterized by mucocutaneous candidiasis (CMC), hypoparathyroidism (HP) and primary adrenal insufficiency (AI). Two of these three components are required for diagnosis.Objective and hypotheses: To describe Russian patients in terms of clinical, genetic, and immunological parameters....

Background: Screening for congenital hypothyroidism (CH) in the Russian Federation started in 1994. A survey was conducted in 1994 on the basis of 32 laboratories, and since 2007 newborn screening is being carried out in 79 laboratories of 83 regions of the Russian Federation.Objective and hypotheses: To study the prevalence of CH in Russia and in different regions of the Russian Federation.Method: Official statistics on CH screeni...

Background: GH therapy for GH deficient (GHD) children in Russia is fully state funded as part of the ‘Seven high expenditure diseases’ (7HED) federal program. Thus, it is important to thoroughly understand the disorder, including its epidemiology. In Russia, there are two parallel functioning registries: the official federal medical statistics (OFMS) which provides purely statistical information and the 7HED registry which must contain a patient’s data to make ...

Background: Congenital hyperinsulinism (CHI) is a common cause of hypoglycaemia in neonates, infants and children. CHI is a heterogeneous disease in terms of clinical presentation, genetics and histology.Objective and hypotheses: The aim of this study was to describe the clinical characteristics, genotype–phenotype correlations and treatment outcome of Russian patients with CHI.Method: A total of 90 children with CHI were iden...

Background: Nonclassical 21-hydroxylase deficiency (NC21OHD) is one of the most common monogenic diseases. Its frequency varies significantly among different ethnic groups. In Russians the frequency of NC21OHD is unknown.Objective and hypotheses: To estimate the incidence of NC21OHD in Russia based on the carrier frequencies of the two most common mutations associated with this disease (V281L and P30L).Method: A total of 998 random...

Dominant activating mutations in GCK gene are known to be the cause of congenital hyperinsulinism (CHI). Patients with GCK mutations can have a wide range of clinical presentations, varying from asymptomatic adult onset hypoglycemia to medically unresponsive severe neonatal onset HI. Overall, 5 of 214 (2.3%) patients diagnosed with HI over the last 10 years in Russia were found to carry pathogenic variants of GCK gene. Only 2 of these 5 patients ...
