Polymorphisms and genetic susceptibility of type 1 diabetes mellitus and celiac disease
نویسندگان
چکیده
Background Type 1 diabetes mellitus (T1D) is a chronic autoimmune disease characterized by pancreatic beta-cell destruction, hyperglycemia and progressive insulin deficiency, affecting mainly children and adolescents genetically predisposed. About 10% (2.4-16.4%) of T1D individuals develop celiac disease (CD), an immune-mediated enteropathy triggered by gluten exposure. Both diseases have a common autoimmune origin and share a similar genetic Background, the major histocompatibility complex class II antigen (HLA-DQ). Some genetic association studies have also identified susceptibility polymorphisms nonHLA associated to both diseases, located in different genes: RGS1 (rs2816316), IL2-IL21 (rs6822844), BACH2 (rs11755527) and IL18RAP (rs917997).

Genetic Polymorphisms of Estrogen Receptors in Iranian Women with Diabetes and Coronary Artery Disease
Estrogen might play an important role in the pathogenesis of diabetes mellitus type 2. Estrogens inhibit diabetes via distinct mechanisms particularly by reducing both hyperglycemia and plasma insulin levels. Estrogen exerts its physiological effects mainly through estrogen receptors including α and β types. Estrogen receptors are found in many tissues that participate in the pathogenesis of ty...

The association of celiac disease and type I diabetes mellitus has been known for some time. This study was undertaken to investigate the prevalence of celiac disease (CD) in diabetic children and adolescents. Eighty-seven patients (44 females, 43 males) aged 2- 18 years, with type I diabetes participated in this study. A group of 87 healthy unrelated girls and boys matched for age and gend...
متن کاملType 1 Diabetes Mellitus, Celiac Disease, and Selective IgA Deficiency: a Case Report
Patients with Type 1 diabetes mellitus have a high prevalence of coeliac disease, symptoms of which are often mild, atypical, or absent. Untreated coeliac disease is associated with an increased risk of malignancy, particularly of lymphoma. Therefore, we report a 9-year-old girl with Coeliac disease, diabetes type 1 and Selective IgA deficiency. A 9-year-old female patient presented in august 2...
متن کاملPrevalence of celiac disease in children under-18 years old with diabetes mellitus type I
Background: Celiac disease is a chronic inflammation of small intestine which is caused by an increased permanent sensitivity to a protein named gluten. This protein is present in some cereals such as wheat, barley, and rye. The immunologic response to this protein can cause clinical symptoms in people with specific human leukocyte antigens (HLAs) (including HLADQ2 or HLADQ8). Most studies have...

Background: Both genetic and environmental factors are important in pathogenesis of diabetes. Non HLA (Human Leukocyte Antigen) genes such as INS-VNTR and CTLA-4 in addition of HLA genes have influence on genetic susceptibility for diabetes mellitus. In this study the association of +49 A/G CTLA-4 and -23 A/T INS-VNTR polymorphisms with diabetes and their association with islet auto...
