Vitamin D Status in Inflammatory Bowel Disease

2018-04-19 10:03:12 | BioPortfolio

Summary

Inflammatory bowel disease (IBD), comprising crohn's disease (CD) and ulcerative colitis (UC), is a a chronic, relapsing-remitting systemic disease. Vitamin D is a secosteroid hormone that possesses immunomodulatory properties and has been demonstrated to potentially influence inflammatory bowel disease (IBD) pathogenesis and activity.

Description

Inflammatory bowel disease (IBD), comprising crohn's disease (CD) and ulcerative colitis (UC), is a a chronic, relapsing-remitting systemic disease and it is increasing sharply with rapidly increasing proportion in developing countries., and the common medications are not effective for most patients.The key underlying pathogenic mechanisms for both diseases is a dysregulated host immune response to commensal intestinal flora in genetically susceptible individuals.Vitamin D is a fat-soluble vitamin, a secosteroid hormone whose active form, calcitriol or 1,25-dihydroxyvitaminD3 (1,25(OH)2D3) plays important roles in immune regulation, particularly involving the innate immune system, cell differentiation and intercellular adhesion, promotes the production of anti-microbial peptides, including β-defensins and cathelicidins, the shift towards Th2 immune responses, and regulates autophagy and epithelial barrier integrity.The relationship between vitamin D deficiency and IBD is bidirectional that vit D with its immunomodulatory effects influence IBD pathogenesis and activity and IBD itself can lead to vitamin D deficiency.Vitamin D deficiency has associated with increased IBD activity scores, lower quality-of-life, an increased risk of IBD-related surgery and increased hospitalizations.[4]. Vitamin D downregulate powerful proinflammatory cytokines, such as TNF, which enhance the durability of anti-TNF therapy in IBD and its deficency has been found to be associated with earlier cessation of anti-TNFα therapy( loss of response to biologic therapy.

Medical and Biotech [MESH] Definitions

All blood proteins except albumin ( = SERUM ALBUMIN, which is not a globulin) and FIBRINOGEN (which is not in the serum). The serum globulins are subdivided into ALPHA-GLOBULINS; BETA-GLOBULINS; and GAMMA-GLOBULINS on the basis of their electrophoretic mobilities. (From Dorland, 28th ed)

An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.

Immune complex disease caused by the administration of foreign serum or serum proteins and characterized by fever, lymphadenopathy, arthralgia, and urticaria. When they are complexed to protein carriers, some drugs can also cause serum sickness when they act as haptens inducing antibody responses.

Proteins that are present in blood serum, including SERUM ALBUMIN; BLOOD COAGULATION FACTORS; and many other types of proteins.

Serum albumin from humans. It is an essential carrier of both endogenous substances, such as fatty acids and BILIRUBIN, and of XENOBITOICS in the blood.
