Abstract

Background/aims: Inappropriate down regulation of an activated immune system is considered as the main pathogenetic mechanism in inflammatory bowel disease. Migration of circulating cells to a diseased intestine is considered as an important factor in the pathogenesis of inflammatory bowel disease. We aimed to evaluate some features of circulating immune cells in inflammatory bowel disease. Methods: Twenty-two control, 29 Crohn’s disease and 17 ulcerative colitis patients were studied. CD2, CD3, CD4, CD8, CD11b, CD11c, CD25, CD45RA, CD45RO, CD54 and HLA DR on the surface of peripheral blood lymphocytes and CD11b, CD11c, CD45RA and CD45RO on the phagocytes were researched with two-color immunofluorescence flow cytometry. Results: The percentages of CD2+ and CD4+ lymphocytes were found significantly reduced in ulcerative colitis. CD3+ and CD8+ lymphocytes in inflammatory bowel disease were higher than in controls. CD45RA+ lymphocytes were found significantly decreased in ulcerative colitis and active Crohn’s disease. CD45RO+ lymphocytes and CD45RO+, CD11b+ and CD11c+ phagocytes were significantly increased in Crohn’s disease. Conclusions: We demonstrated that there were significant differences between ulcerative colitis and Crohn’s disease in the expression of some important surface markers on the peripheral blood immune cells. It seems that circulating CD11b-CD11c and CD45RA-CD45RO expressing phagocytes are important in inflammatory bowel disease and may be useful in distinguishing Crohn’s disease from ulcerative colitis. These findings may give us some clues about the immunopathogenesis of inflammatory bowel disease.

Özet

Amaç: Aktive olmuş immün sistemin uygunsuz down-regülasyonu, inşamatuvar barsak hastalığında ana patogenetik mekanizma olarak kabul edilmektedir. Dolaşımdaki immün hücrelerin hastalıklı barsağa göçü inşamatuvar barsak hastalığının patogenezinde önemlidir. ‹nşamatuvar barsak hastalığında, dolaşımdaki immün hücrelerin bazı özelliklerini araştırmayı amaçladık. Yöntem: Yirmi iki kontrol, yirmi dokuz Crohn ve on yedi ülseratif kolit hastası incelendi. Periferik kan lenfositleri üzerinde CD2, CD3, CD4, CD8, CD11b, CD11c, CD25, CD45RA, CD45RO, CD54 ve HLA DR ekspresyonu, periferik kan fagositleri üzerinde ise CD11b, CD11c, CD45RA ve CD45RO ekspresyonu iki renkli immünşörosans şow sitometrisi ile çalışıldı. Bulgular: CD2+ ve CD4+ lenfositlerin oranı, ülseratif kolitte önemli miktarda azalmış bulundu. CD3+ ve CD8+ lenfositler inşamatuvar barsak hastalığında kontrollerden daha fazlaydı. CD45RA+ lenfositler, ülseratif kolit ve aktif Crohn hastalığında, önemli miktarda azalmış bulundu. CD45RO+ lenfositler ile CD11b+ ve CD11c+ fagositler Crohn hastalığında önemli oranda artmış bulundu. Sonuç: Periferik kan immün hücreleri üzerinde bulunan birtakım önemli yüzey markırlarının ekspresyonunda ülseratif kolit ile Crohn hastalı- ğı arasında önemli farklılıklar olduğunu gösterdik. Bulguları- mız, dolaşımdaki CD11b-CD11c ile CD45RA-CD45RO eksprese eden fagositlerin inşamatuvar barsak hastalığında önemli olabileceğ i ve Crohn hastalığını ülseratif kolitten ayırt etmede yardı mcı olabileceğini düşündürtmektedir. Bu bulgular, inşamatuvar barsak hastalığının immünopatogenezi hakkında bize bazı ip uçları verebilir.
