Abstract:
OBJECTIVES:Cytokine production from activated T cells play a pathogenetic role in mucosal lesions of coeliac disease (CD). Active interleukin (IL)-18 is expressed in the small intestinal mucosa in CD but not in healthy controls. IL-18 enhances intercellular adhesion molecule-1 (ICAM-1) expression. We analyzed IL-18 serum levels in CD patients before and after gluten-free diet and the possible correlation with soluble ICAM-1 (sICAM-1) serum levels. METHODS:The study comprises ten CD patients before and after gluten free diet and ten healthy controls. Serum IL-18 and sICAM-1 levels were assayed by immunoenzymatic methods. RESULTS:Serum IL-18 and sICAM-1 levels were significantly higher in patients with CD before diet with respect to healthy controls (P<0.05), with a highly significant correlation between the two parameters (Rho=0.800, P=0.0167). Gluten free diet significantly reduces IL-18 and sICAM-1. CONCLUSION:Our findings show that IL-18 serum concentrations correlated with the clinical status of CD patients suggesting a role for this cytokine in the pathophysiology of this disease.
