Abstract

Objective: A strong correlation exists between tenascin-C induction, and acute inflammation. Generally increased tenascin-C concentrations are correlated with various inflammatory, and infectious diseases. In patients with diagnosis of Inflammatory Bowel Disease (IBD) presence of tenascin-C in colonic mucosa demonstrates tissue repair, and its mucosal concentrations are correlated with local disease activity Therefore plasma levels of tenascin-C have been demonstrated to be a helpful indicator of the activity of inflammatory bowel diseases. In this study, firstly in the literature, we aimed to display the correlation between tenascin-C expression, and formation of intestinal stricture.

Methods: A total of 43 patients (male, n=19; 44.2%; and female, n=24, 55.8%) aged between 19, and 63 years, with clinically, endoscopically, radiologically, and histopathologically confirmed definitive diagnosis of Crohn's disease who were examined, diagnosed, and treated in the Gastroenterology Clinic of Haydarpasa Numune Training and Research Hospital between January 2011, and April 2012 were investigated. Serum tenascin-C levels were measured using commercial sandwich enzyme-linked immunosorbent assay Human Tenascin-C Purified Protein kit (Chemicon, Millipore(R), USA). Study groups were categorized based on the type of the disease as inflammatory (n=17; 39.5%), obstructive (27.2%), and fistule formation (n=10; 23.3%) Crohn's disease. For statistical analysis SPSS (Statistical Package for Social Sciences) Statistics 15 program was used.

Results: Median tenascin- C value in the obstructive group (6.57 ng/mL; range, 4.26-21.87 ng/mL) was statistically significantly higher than that detected in the inflammatory (1.74 ng/mL; range,1.29-3.16 ng/mL), and fistulizing (1.44 ng/mL; range, 0.74-2.47 ng/mL) groups (p=0.002).

Conclusion: Intestinal fibroblasts have an important role in the stricture formation process in CD. Transforming growth factor (TGF)-b1 cytokine is in the center of this process. A strong correlation exists between tenascin-C induction, and acute inflammation. As a known fact, serum tenascin-C levels can be used in the determination of activity of IBD. Starting from this point, serum tenascin-C levels can be useful in the categorization of the Crohn's disease without the need for invasive methods. In the future, studies with larger patient series investigating use of serum tenascin-C in the prediction of stricturing Crohn's disease should be conducted.
