ABSTRACT

INTRODUCTION: The aim of our study was to evaluate the diagnostic characteristics of selected inflammatory markers and the results of multiplication of their concentrations in the diagnosis and assessment of Crohn's disease (CD) activity. METHODS: We studied 49 patients with CD and 31 healthy controls. The CD patients were assigned to subgroups with active and inactive disease based on the Crohn's Disease Activity Index score. Serum interleukins and C-reactive protein (CRP) were measured using immunoassays. RESULTS: Serum CRP and interleukins: IL-6, IL-17A, IL-23 were significantly higher in the CD group than in controls, with the best diagnostic performance for IL-23. Only serum IL-6 and CRP were significantly higher in active than in inactive disease, with the better performance of CRP. Multiplication results did not perform better than individual multipliers. CONCLUSIONS: Serum CRP may be useful in the assessment of CD activity and there is a need for introduction of IL-23 for the CD diagnosis.

ABSTRACT

INTRODUCTION: Endothelial dysfunction leads to an increased expression of cell adhesion molecules, leukocyte diapedesis, vascular smooth­muscle tone, excessive permeability of vascular walls, and increased procoagulant activity. OBJECTIVES: We investigated whether serum levels of several endothelial and platelet activation markers correlated with disease activity in patients with inflammatory bowel disease (IBD). PATIENTS AND METHODS: This study included 56 patients with ulcerative colitis, 66 with Crohn disease, and 40 healthy controls. We measured the complete blood count and levels of fibrinogen, C­reactive protein, albumin, interleukin 6, tumor necrosis factor α, E­selectin, P­selectin, monocyte chemoattractant protein 1 (MCP­1), soluble CD40 ligand (sCD40L), and microparticles. RESULTS: There were no significant differences in the median levels of E­selectin, P­selectin, MCP­1, sCD40L, and microparticles between patients with active IBD, those with inactive IBD, and healthy controls. The clinical disease activity assessed with the Mayo scale in the ulcerative­colitis group was weakly, positively correlated with sCD40L (R = 0.32, P = 0.02), P­selectin (R = 0.32, P = 0.02), and inflammatory marker levels. The clinical disease activity index in the Crohn disease group was positively correlated with the markers of inflammation yet not with the markers of endothelial activity. CONCLUSIONS: E­selectin, P­selectin, sCD40L, MCP­1, and microparticle levels do not significantly differ between patients with the varying activity of IBD. However, due to the observed correlations, further studies of a larger patient group should be conducted to confirm our observations.

ABSTRACT

Oxidative stress (OxS) has been implicated in the pathogenesis of Crohn's disease (CD). The aim of this study was to examine whether nonenzymatic antioxidants are associated with active CD, by using the FRAP and GSH assay in plasma. Additionally, we measured bilirubin and albumin levels as two individual components of the plasma antioxidant system. A total of 55 patients with established CD, 30 with active CD and 25 with inactive disease, and 25 healthy individuals were prospectively enrolled in this study. We evaluated CD activity index, BMI and blood morphology, platelet count, serum CRP level, and bochemical parameters of OxS: ferric reducing ability of plasma (FRAP), reduced glutathione (GSH) in plasma and bilirubin and albumin levels in serum. Plasma FRAP and GSH concentrations were decreased in both CD groups compared to controls and negatively correlated with CDAI values (FRAP: r = -0.572, p = 0.003; GSH: r = -0.761, p = 0.001), CRP and platelet count. Bilirubin and albumin levels were lower in the serum of active CD patients than inactive CD patients and controls and negatively correlated with the CD activity index (r = -0328, p = 0.036, r = -0.518, p = 0.002) and CRP (r = -0.433, p = 0.002). e decreased FRAP and GSH levels in plasma and bilirubin and albumin levels in serum of patients with active CD compared to inactive CD and controls underlines the importance of OxS in the pathophysiology and activity of CD.

ABSTRACT

INTRODUCTION: In patients with inflammatory bowel disease (IBD), disbalance between procoagulant, anticoagulant, and fibrinolytic factors has been shown. The hemostatic system is an indispensable component of the inflammatory process. Deficiencies in the protein C (PC) pathway components not only promote thrombosis, but also exacerbate inflammation. OBJECTIVES: The aim of the study was to assess the components of the PC system and their correlations with disease activity in patients with IBD. PATIENTS AND METHODS: The levels of PC, free protein S (PS), and soluble thrombomodulin (sTM) were measured in 55 consecutive patients with ulcerative colitis (UC), 50 patients with Crohn's disease (CD), and 41 healthy volunteers. Correlations between PC system components and disease activity, hemostatic variables, and inflammatory markers were assessed. RESULTS: sTM levels in patiens with UC were higher compared with controls (24.5 vs. 17.5 ng/ml; P = 0.0042). In patients with IBD, PC activity was higher and PS activity was lower compared with controls (P <0.001). Tumor necrosis factor α (TNF-α) levels were higher in patients with IBD, and interleukin 6 (IL-6) levels were higher only in patients with CD. In patients with UC, a positive correlation was observed between sTM and both PC and PS levels (r = 0.28 and r = 0.34, respectively, P <0.05). Only PC levels correlated with UC activity (r = 0.3, P <0.05). No correlations of TNF-α, IL-6, and C-reactive protein with PC, PS, and sTM levels were observed. CONCLUSIONS: The PC pathway is defective in patients with CD and UC. Hypercoagulability in IBD might be associated not only with the inflammatory process but also with disturbances in the anticoagulant system, since defective PC pathway was observed both in active and nonactive disease.
