Background: 3β-Hydroxysteroiddehydrogenase (3β-HSD) is a key enzyme in steroidogenesis, responsible for the conversion of Δ5- to Δ4-steroids. Deficiency in 3β-HSD results in congenital adrenal hyperplasia (CAH). The molecular etiology of 3β-HSD deficiency lies in a defect in HSD3B2 gene.Clinical case: A healthy newborn girl was admitted on day of life (DOL) 8 due to increased 17-OH-progesterone (17OHP) in newborn sc...

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: Anorexia nervosa (AN) is associated with a number of endocrine abnormalities including a low serum free thyroxine level. Hypothyroidism in AN is a recognised condition which is associated with a low normal free thyroxine and triiodothyronine levels (FT4, FT3) with an elevated reverse T3 (rT3). Serum TSH levels are normal or slightly reduced, suggesting a hypothalamic origin to the suppressed thyroid function which is norm...

Background: Fulminant type 1 diabetes (FT1D) is presented as a severe diabetes subtype among adults, however, we have no idea whether it’s worth being taken seriously among children and adolescents.Objective and hypotheses: We aim to clarify the clinical significance of the subtype. It’s supposed that we may needn’t pay special attention to the subtype.Method: Case–control study design. Data from hospitalized al...

The pathogenesis of altered bone metabolism leading to bone mass loss and fractures in patients with cystic fibrosis (CF) is complex, and can involve malnutrition, malabsorption, lack of physical activity, vitamin D and K insufficiency, systemic inflammation, respiratory failure, liver disease, hypogonadism, and treatment with glucocorticosteroids. Many studies reported osteopenia, osteoporosis and fractures in adults with CF, with bone loss starting at an earlier age than in ...

Background: Dominant mutations in ABCC8 can cause congenital hyperinsulinism (CHI), which is characterised by unregulated insulin secretion.Objective and hypotheses: To understand the molecular basis of medically unresponsive CHI due to dominant ABCC8 mutations.Method: We investigated ten patients with diazoxide unresponsive CHI who required a near total pancreatectomy. DNA sequencing revealed seven dominant heter...

Background: Long-acting somatostatin analogues have been reported to be an effective treatment option to prevent severe hypoglycaemia in children with severe diffuse congenital hyperinsulinism (CHI). Possible side effects include gallstones, growth retardation and necrotizing enterocolitis (NEC), the latter occurring in particular cases of newborns treated with octreotide. So far only short-acting octreotide is being used in early infancy, requiring multiple injections daily o...

Background: The recent evidence has shown that the skeleton can in turn affect carbohydrate metabolism.Objective and hypotheses: To analyse associations between serum level of sclerostin and as well other bone-related molecules as adipokines and some markers of glucose and lipid metabolism in children and adolescents.Method: 57 patients, 40 with type 1 diabetes mellitus (T1DM), 17 with obesity, and 11 control, healthy age- and BMI-...

Background: The 12q14.3q15 microdeletion syndrome is a rare entity of which only 16 new cases have been described to date. The syndrome consists of the association of severe pre- and postnatal growth retardation, proportional short stature, psychomotor retardation and osteopoikilosis. The phenotypic appearance of these patients poses a differential diagnosis with Silver-Russell syndrome, among other entities.Clinical description: A 10-month-old boy was r...

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...
