Circulating levels of chemerin and adiponectin are higher in ulcerative colitis and chemerin is elevated in Crohn's disease


Weigert, J; Obermeier, F; Neumeier, M; Wanninger, J; Filarsky, M; Bauer, S; Aslanidis, C; Rogler, G; Ott, C; Schäffler, A; Schölmerich, J; Buechler, C (2010). Circulating levels of chemerin and adiponectin are higher in ulcerative colitis and chemerin is elevated in Crohn's disease. Inflammatory Bowel Diseases, 16(4):630-637.

Abstract

BACKGROUND:: Chemerin is an adipokine that stimulates chemotaxis of cells of the innate immune system. Inflammatory bowel disease (IBD) is linked to an impaired immune response and, therefore, we hypothesized that systemic chemerin may be altered in IBD patients. METHODS:: Serum was collected from patients with Crohn's disease (CD, 230 patients), ulcerative colitis (UC, 80 patients), and healthy controls (HC, 80 probands). Chemerin and adiponectin, which has already been measured in the serum of similar cohorts by others, were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS:: Chemerin was elevated in IBD compared to HC and was higher in male CD than UC patients. Female and male CD patients had lower adiponectin levels compared to UC, and adiponectin was lower in female CD patients compared to female HC. Adiponectin tended to be higher in female and male UC patients compared to HC and this difference became significant in the whole study group. Correlations with disease activity were only found in males. Here, chemerin was higher in CD patients on remission but was reduced in UC with nonactive disease. Adiponectin was higher in UC with inactive disease. Treatment with corticosteroids was linked to elevated adiponectin in male CD patients and higher chemerin in female UC patients. Unlike adiponectin, which was elevated in female serum in all cohorts, chemerin was only higher in female UC patients. CONCLUSIONS:: These findings further indicate potential regulatory functions of adipokines in intestinal inflammation that are partly gender-dependent and that may even be associated with the distinct immunopathogenesis of UC and CD. (Inflamm Bowel Dis 2009;).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
