Objective: Addison’s disease (AD) is a rare and complex endocrine disorder. Genetic susceptibility loci known so far are predominantly shared with other, more frequent autoimmune endocrinopathies. We therefore investigated polymorphisms of the CTLA4-region, the vitamin D system (vitamin D receptor VDR, CYP24 and CYP27B1 gene) as well as cytokine CXCL10 gene for their association in AD.Methods: Patients with AD (n=203) and healthy controls (<i...

Background and aims: CXC chemokine ligand 10 (CXCL10) also known as chemokine interferon γ inducible protein (IP-10) is a CXCR3 chemokine belongs to a group of structurally related molecules, that induce the chemotaxis of diverse leukocyte subtypes including activated T-helper 1 lymphocytes, natural killer cells and monocytes. In patients with Hashimoto’s thyroiditis, type 1 diabetes mellitus and Graves’ disease high levels of CXCL10 ligand in serum have been fo...

Background/aim: Vitamin D receptor (VDR) expression has been shown to be upregulated in several tumors and is thought to represent an important endogenous response to tumor progression. Therefore, in order to evaluate the role of VDR-gene and of the 25(OH)-Vitamin D3 in thyroid cancer we analysed four polymorphisms in patients with thyroid cancer and healthy controls.Patients and methods: Patients (n=136; 84 females and 52 males) with d...

Background: Previously, we reported an association of vitamin D receptor (VDR) polymorphisms and differentiated thyroid cancer (DTC) risk. The aim of the present study was to investigate other vitamin D pathway genes such as CYP27B1, CYP2R1 and CYP24A1 which code for enzymes that, respectively, synthesize and degrade 1,25(OH)2D3 in patients with DTC and healthy controls (HC). Also its influence on 25(OH)D3 and 1,25(OH)2D3 ...
