Background: Klinefelter syndrome (KS) is the most common cause for hypergonadotropic hypogonadism. Patients with 47,XXY karyotype often have increased gonadotropin levels at early puberty, which stay high during adolescent and adult life due to hyalinisation of seminiferous tubules of testes. We report a clinical case of 47, XXY KS patient with low gonadotropin levels.Clinical case: A boy was referred to an endocrinologist at the age of 12,5 years due to...

Background: Type 1 insulin-like growth factor receptor (IGF-1R) is the product of a single-copy gene located on chromosome 15 and is ubiquitously expressed in humans. Increased hepatic IGF-1R gene expression is found in hepatocellular carcinoma and in chronic hepatitis C, making parenchymal and non-parenchymal cells more susceptible to the mitogenic effects of IGF-1.Objective and hypotheses: As we have previously demonstrated that IGF-1 and IGF-2 circula...

Objective and hypotheses: To evaluate endocrine risk factors of testicular cancer of children with testicular microlithiasis.Method: Under research were 74 patients with testicular microlithiasis (average 11.41±4.02). Heredity, case history, endocrine diseases, anthropometric indicators, ultrasound of the scrotum were evaluated.Results: At 20 of 74 (27%) children microlithiasis was combined with strong risk factors of testicle...

Objective: To study clinical and laboratory characteristics of patients with disorders of sex development (DSD) 45,X/46,XY.Subjects and methods: It was included 248 patients with genital ambiguity, which were divided into groups based on cytogenetic survey. All children with mosaicism 45,X/46,XY evaluated the structure of the external genitalia on the external masculinization score (EMS, range 0–12), ultrasound examination, the definition of anti-Mu...

Objective and hypotheses: To examine anthropometric, hormonal characteristics and their relationship in boys with constitutional delay of puberty (CDP).Method: The study included 47 boys older 13.2 year old with CDP. It evaluated anthropometric indicators, bone age and hormonal status.Results: The patients were divided: the first group consisted of 25.5% (12/47) of boys with pathological growth (Median/Me Ht-SDS=−2.3). Of the...

Background: The antioxidant system that protects tissues from damaging oxidation processes is a universal indicator for metabolic balance. It is known that GH deficiency (GHD) is associated with a high risk of developing metabolic disorders.Objective and hypotheses: The aim of this study was to examine the effects of inadequate GH secretion on the markers of the blood antioxidant system in adult GHD patients.Method: The study inclu...

Background: Endogenous GH pattern is characterized by high peaks (growth signal) and low trophs (metabolic signal). Exogenous GH is given by subcutaneous injection (scGH-injection) daily at bedtime.Objective and hypotheses: To study the factors influencing intra-/interindividual variation of pharmacokinetics and pattern of scGH-injection in GH treated children.Method: One hundred and twenty eight subjects followed yearly ≤ 8 ...

Background: GH-secretion rates for children ranges in pre/early puberty 0.1–11 U/24 h and during mid-puberty 4–40 U/24 h. This can be used to optimize the rhGH treatment doses in children.Objective and hypotheses: To calculated the bioavailable rhGH in relation to injected dose and compare this to GH-secretory rate in healthy children; and to investigate factors influencing bioavailability.Method: One hundred and twenty e...

Background: Jacobsen syndrome is a rare genetic condition caused by partial deletion of the long arm of chromosome 11 associated with delayed development, distinctive facial features, bleeding disorder, skeletal abnormalities and endocrine disorders.Case report: We report a rare case of Jacobsen syndrome in 4 year old boy addressed for short stature. Born at term (36 W) with low birth weight (1780 g) and delayed development, his height at presentation wa...

Background: Pseudohypoparathyroidism is a group of rare disorders characterized by tissue insensitivity to PTH and Albright hereditary osteodystrophy (AHO) due to inactivating mutations or epigenetic defects of the GNAS.Objective and hypotheses: Clinical features and molecular characteristics of patients with PHP have been examined.Method: We included 28 patients from 26 families with PHP1a and 1b. GNAS mutation analysis w...
