Abstract

Background/Aims: Eosinophilic cationic protein is a cytotoxic substance released by eosinophilic granulocytes. Patients with inflammatory bowel disease have a pronounced infiltration of eosinophils in the lamina propria of the intestinal cells and in the mucosal exudate. The aim of this study was to investigate ECP levels and their relationship to disease activity and location in serum of patients with inflammatory bowel disease. Methods: Fifty-four patients were examined, of whom 33 had ulcerative colitis, seven Crohn's disease and 14 were healthy controls. Disease activity was evaluated from endoscopic findings. In patients with ulcerative colitis mucosal inflammation was graded between 0 and 3, while in patients with Crohn's disease a Simple index was used. Results: Significantly elevated levels of ECP were found in patients with ulcerative colitis compared to the control group (Mann Whitney-U test; p=0.03 , U=32), but not in patients with Crohn's disease (p=0.08 , U=25) . Particularly high levels of ECP were found in patients with the most active disease in the ulcerative colitis group (r=0.59 ; p= 0.0016). However, there was no relationship between ECP levels and disease location in either group. Conclusions: This study indicates that eosinophils and their mediators may be involved in the pathogenesis of ulcerative colitis and correlate with disease activity. ECP may have a potential as a simple, non-invasive diagnostic test.

Özet

Amaç: Eozinofilik katyonik protein, eozinofillerden salınan sitotoksik bir proteindir. İnflamatvuar bağırsak hastalıkları, intestinal hücrelerin lamina propria ve mukoza eksüdalarında belirgin bir eozinofil infiltrasyonu ile karakterizedir. Bu çalışmanın amacı, inflamatuvar bağırsak hastalıkları, mevcut olan hastalarda eozinofilik katyonik protein seviyesini ve hastalığın aktivitesi-lokalizasyonu ile olan ilişkisini araştırmaktı. Yöntem: 54 hasta çalışmaya alındı. 33 ülseratif kolit, 7 Crohn's hastalığı ve 14 tanesi kontrol idi. Ülseratif kolitli hastalarda, hastalığın aktivitesi endoskopik bulgular ile mukozal inflamasyon göz önüne alınarak 4 grade üzerinden değerlendirildi. Crohn's hastalığında ise aktivite için Simple index kullanıldı. Bulgular: Eozinofilik katyonik protein seviyesi, kontrol grubu ile karşılaştırıldığında ülseratif kolitli hastalarda anlamlı derecede artmış olarak bulundu (Mann Whitney-U testi; p=0.03 , U=32). Crohn hastalığında ise istatistiksel bir farklılığa rastlanılmadı (p=0.08, U=25 ). Özellikle, yüksek seviyedeki ECP değerleri aktif ülseratif kolitli hastalarda bulundu (r=0.59 ; p= 0.0016). Her iki grupta da eozinofilik katyonik protein seviyesi ile hastalığın lokalizasyonu arasında bir ilişki görülmedi. Sonuç: Bu çalışma eozinofil ve mediatörlerinin ülseratif kolit patogenezinde rol oynayabileceğini ve hastalığın aktivitesi ile ilişkili olduğunu göstermektedir. Ayrıca, eozinofilik katyonik protein basit, non-invasive diagnostik bir test olarak ta kullanılabilecek potansiyele sahiptir.
