Objective: The clinical, laboratory and prognostic findings of the patients diagnosed with Kowarski Syndrome (biologically inactive growth hormone) were evaluated between February 2009 and February 2019 in order to contribute to literature.Materals and Methods: 110 cases diagnosed with Kowarski syndrome between February 2009 and February 2019 were evaluated retrospectively. 97 cases continued to work. 92 cases at least one year, 62 cases...

Context: There is a limited data from large cohorts regarding pubertal characteristics of children with classical 21-hydroxylase deficiency(21OHD).Objective: To explore the timing and tempo of puberty, and pubertal height gain(PHG) in children with 21OHD-CAH.Design: A multicenter observational, retrospective, longitudinal analysis.Patients: D...

Background: Androgens play a pivotal role in non-reproductive tissues, such as the kidney, heart, and liver, as well as the pancreas. Since the androgen receptor is expressed in pancreas and liver cells, this raises the possibility that excess testosterone results in insulin hypersecretion, and in fetuin-A, a protein produced in the liver. However, whether fetuin-A and insulin levels are affected by androgens in classic congenital adrenal hyperplasia (CAH) due...

Background: Osteogenesis imperfecta (OI) is a genetic disorder characterized by diffuse osteoporosis, recurrent fractures, and resulting deformities. Bruck syndrome (BS) is a rare autosomal recessive disease that manifests with many symptoms of OI. In addition to the deficiency of type I collagen in OI, congenital joint contractures also occur in BS. BS is caused by mutations of FKBP10 (BS type 1) and PLOD2 (BS type 2) genes encoding the chaperone-collagen com...

Polycystic ovary syndrome is the most common endocrinological disease in women of reproductive age. Although it is thought that pathologies such as insulin resistance, chronic low-level inflammation and hyperandrogenism are central theme of the disease, the exact pathophysiology of the disease has not been fully understood. This study’s aim is to reveal the relationship between routine endocrinological and immunological markers related to chronic inflammation, and to inv...

Objective: Thyroid hormone resistance is a rare autosomal dominant disease. In the pathogenesis of this disease mutations have been reported in two types of thyroid hormone receptors, called alpha and beta. Deletions or mutations in cofactors required to demonstrate receptor effect also reported in the beta receptor gene. The symptoms vary according to the cases. Here; a case of thyroid hormone resistance which is noticed by chance and not treated is presented.<p class="ab...

Background: GH deficiency (GHD), can either be isolated (IGHD) or part of multiple pituitary hormone deficiency (MPHD), is a pituitary hormone disorder that manifests with short stature.Objective and hypotheses: To evaluate the presenting characteristics, auxological and etiologic factors of GHD in a large cohort from a single tertiary paediatric endocrine centre.Methods: Hospital files of patients followed with GHD deficiency at D...

Background and objective: The first and rate-limiting step of steroidogenesis is the conversion of cholesterol to pregnanolone which is catalyzed by the P450scc side chain cleavage enzyme (encoded by CYP11A1 gene-SCC). Homozygous recessive mutations of the CYP11A1 gene cause a global steroid hormone deficiency thereby disorders of sexual development in 46, XY individuals with a variable phenotype depending on the mutation characteristics. About 60 cases of SCC...

Context: Polycystic ovary syndrome (PCOS) is defined by androgen excess and ovarian dysfunction in the absence of a specific physiological diagnosis. The best clinical marker of androgen excess is hirsutism, while the best biochemical parameter is still a matter of debate. Current consensus guidelines recommend serum free testosterone as the most sensitive serum parameter to measure androgen excess. Recently, however, novel active androgens and androgen metabo...

The physiology of adrenarche, i.e. the development of the zona reticularis of the adrenal cortex, is mostly unknow. Some genes of steroidogenic enzymes need to be down- (HSD3B2) while others upregulated (e.g. CYB5) to enhance androgen production in zona reticularis, but it is not known how this is regulated. Micro RNAs (miRNAs) are small non-coding RNAs that can affect gene expression at posttranscriptional level. We hypothesized that miRNAs might be involved in regulating adr...
