Background: In autoimmune thyroiditis type Hashimoto the key role in thyrocytes destruction plays the spontaneous cytotoxic activity of T cells, and antibodies dependent mechanisms are of a less value. A spontaneous cytotoxicity is associated with the number and degree of activity of NK cells. An important role in this process plays perforin contributed in permabilization of target cells.Objective and hypotheses: The aim of the study was to evaluate the ...

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: Most of autoimmune disease such as type 1 diabetes (T1DM), autoimmune thyroiditis (AIT) and coeliac disease (CD) often coexist in the same patient. Although there are a lot of number of studies on autoimmunity against the thyroid glands and small bowel in patients with type 1 diabetes, little is known about pancreatic β-cell immunity in patients with AIT and CD.Objective and hypotheses: We studied autoimmune markers in children patients ...

Background: Autoimmune polyglandular syndrome type 3 (APS3) comprises a wide spectrum of autoimmune endocrine disorders other than adrenal insufficiency. It includes the association of autoimmune thyroid disease (ATD) with type 1 diabetes (T1D) which is known as APS3 variant (APSA3v). Genes linked to possible joint susceptibility for APS3v have been reported in few cases. We report a 10-year-old girl with Graves’ disease (GD) who developed T1D after 6 years of the diagnos...

Background: Increased prevalence of autoimmune thyroid disease (ATD) in patients with type 1 diabetes mellitus (T1DM) has been extensively described. Since 1996, screening for thyroid disease has been implemented in children and adolescents with T1DM and is performed at least annually.Objective and hypotheses: The aim of this study is to determine the natural history and incidence of ATD in T1DM pediatric patients and the relationship between positive an...

Background: Tuberous sclerosis (TS) is an autosomal dominant neurocutaneous disorder involving many organ systems. The frequency of TS is around one per 5000 to 10 000 live births and is caused by mutation in the TSC1 or TSC2 genes. Autoimmune polyglandular syndrome type 2 (APS2) is an endocrinopathy characterized by two or more autoimmune diseases. Several susceptibility genes are known. The prevalence of APS2 is around 1:20 000.Object...

Background: Disruption of homeostatic functioning of the hypothalamic centres results in hyperphagia, autonomic imbalance, reduction of energy expenditure, and hyperinsulinemia. A syndrome of rapid, unrelenting weight gain is often observed in patients with structural lesions of the hypothalamus. Hypothalamic obesity syndrome (HOS) is often refractory to standard dietary and lifestyle interventions. It has been reported that metformin induces anorectic effects via an increase ...

Background: Childhood tumours of the hypothalamic pituitary axis (HPATs) are very rare and hence any single centre experience is limited. Without evidence-based guidance, treatment is individualised on a case basis. Survival rates are high, but at the expense of significant morbidity. Centralised care or wider multi-professional consultation may improve neuroendocrine and visual outcomes.Objective and hypotheses: i) To facilitate multi-professional dialo...

Background: Thyroid dysfunction is a well-known endocrine complication after cervical irradiation for Hodgkin’s lymphoma (HL). The most common are primary hypothyroidism (20–30%), central hypothyroidism, transient thyroiditis and thyroid cancer. Graves’ disease (GD) is less frequent (5%).Objective and hypotheses: We describe a boy, already diagnosed with thyroiditis, who developed GD during follow-up for severe hypothyroidism following rad...

Introduction: Medulloblastoma is the commonest paediatric brain tumour and accounts for 20–30% of all brain tumours in the first decade of life. Improvements in treatment strategies have enhanced long-term survival resulting in an increased risk of late sequelae.Aim: Review the prevalence of endocrine dysfunction in survivors of medulloblastoma at a single centre.Methods: Case note review of patients treated for medulloblastom...

Background: The incidence of gonadal tumor development varies significantly between subsets of patients with disorder of sex development (DSD). In some female patients with Y chromosome too early gonadectomy is perceived as overtreatment.Objective and hypotheses: The aim of the study was to analyze the gonadal tumor incidence in DSD female patients with 45,X/46,XY or 46,XY.Method: 15 patients, managed at single institution between ...

Background: Noonan syndrome (NS) is a congenital polymalformative disorder caused by aberrant up-regulated signalling through RAS GTPase. Although NS is associated with hematologic malignancies, no predisposition for neuronal tumors was reported so far.Objective and hypotheses: We describe two cases of young patients with NS and dysembryoplastic neuroepithelial tumor (DNET). This is the first case series reporting a rare type of intracranial tumor in NS....

Background: Pituitary gigantism is a rare condition that occurs due to excessive GH secretion during childhood, usually associated with a pituitary adenoma. We describe a case that required the full spectrum of standard therapeutic options available.Case report: A 15-year-old boy presented with a 3-year history of intractable occipital headaches and being psychologically distressed by his tall stature (203 cm). He had mild clinical features of GH excess....
