Expression of Receptor for Advanced Glycation End-products and its Ligands HMGB1 and s100A12 in Children and Adolescents with New-onset Type 1 Diabetes and in Patients with Longer Disease Duration

Background: Receptor for advanced glycation end-products (RAGE) is a multiligand receptor up-regulated at sites of inflammation, especially in tissues with accelerated advanced glycation end-products formation. It is additionally stimulated by RAGE ligands S100A12 and HMGB1 released from recruited immune cells thus perpetuating the inflammatory process with a potential role in the development of type 1 diabetes as well as in development in diabetes complicatio...

Introduction: Oncocytomas are rare epithelial tumors that can be found in various tissues such as kidney, salivary and endocrine glands. Adrenocortical oncocytomas (AON) are very rare tumors with around 160 patients described in the literature. Generally they are regarded as benign and mostly hormonally nonfunctional. When hormonally active, these tumors produce adrenal steroids resulting in various clinical presentations such as virilization, feminization, an...

Unusual Case of Patient with Klinefelter Syndrome with Shox Deletion Born to the Mother with Leri-weill Dyschondrosteosis

Introduction: Klinefelter syndrome (KS) describes the phenotype of the most common sex chromosome abnormality in humans. About 80% of KS patients have 47,XXY karyotype, while rest of the patients can have mosaicism or other numeric or structural sex chromosome abnormalities. Tall stature is one of the hallmarks of KS and it is thought to be due to supernumerary X chromosome leading to SHOX gene overdosage. Deletion of SHOX gene, on the contrary, has been r...

The Association of HLA Class II, CTLA-4 and PTPN22 Genetic Polymorphisms and β-Cell Autoantibodies in Development of Type I Diabetes in Patients with Autoimmune Thyroid Disease

Background: Co-occurrence of type 1 diabetes (T1D) and autoimmune thyroid disease (AITD) denote variant of autoimmune polyglandular syndrome type 3 (APS3v). Thyroid autoimmunity in T1D was widely studied, but a few studies examined β-cell autoimmunity among AITD patients. Several susceptibility genes for APS3v have been identified: HLA class II, CTLA-4 and PTPN22 gene.Objective and hypotheses: To investigate β-cell autoimmunity and genetic poly...
