Abstract

There is little information in the literature about colonic permeability in ulcerative colitis. In this study, the differential urinary excretion of orally administered markers was used to evaluate intestinal permeability in inflammatory bowel disease, especially in Crohn's disease. The aim was to investigate the absorption of $^51$Cr-Labelled ethylenediaminetetraacetic acid ($^51$CrEDTA) and its relationship to disease activity in inflammatory bowel disease.Methods:Thirty-eight patients were examined: 24 had ulcerative colitis, five Crohn's disease and nine were control subjects. 95 $\mu$Ci of $^51$CrEDTA was given orally after an overnight fast and urine was collected for the following 24 hours. Fifth and 24th hour urine samples were used to calculate urinary$^51$CrEDTA as a percentage of the administered dose.Results: Intestinal permeability tested five and 24 hours after $^51$CrEDTA administration was significantly higher in patients with ulcerative colitis than the controls (5 h: ulc col 2.93 ± 2.32; control 0.49 ± 0.47; p= 0.012 / 24 h: ulc col 7.00 ± 5.03; control 1.27 ± 1.03 ; p= 0.011). In addition, patients with Crohn's disease revealed increased intestinal permeability, even though the number of patients in this group was small. There was a significant correlation between intestinal permeability and disease activity in patients with ulcerative colitis (r=0.65; p=0.0006). Conclusions:Oral administration of $^51$CrEDTA is a simple and non-invasive method in evaluating intestinal permeability. Increased urinary excretion of $^51$CrEDTA reflects increased bowel permeability in both large and small bowel inflammation and relates to disease activity.

Özet

Özellikle Crohn Hastalığında olmak üzere, inflammatuvar bağırsak hastalıklarında intestinal permeabilite oral olarak verilen markırların idrardan atılımı ile değerlendirilmektedir. Fakat, ülseratif kolitde kolonik permeabilite hakkında ki bilgiler yeterli değildir. Bu çalışmanın amacı, $^51$CrEDTA ile inflammatuvar bağırsak hastalıklarında permeabiliteyi ve hastalığın aktivitesi ile olan ilişkiyi araştırmaktı. Yöntem: 39 hasta alındı, 24 ülseratif kolit, 5 Crohn hastalığı ve 9 control grubu idi. Bir gece önceden aç olan hastalara 95 $\mu$Ci $^51$CrEDTA oral olarak verildi. Bunu takip eden 24 saatlik period ta idrar toplandı. 5. ve 24. saatlerde iki ayrı idrar örneği alınarak, idrar ile atılan $^51$CrEDTA yüzde olarak hesaplandı. Bulgular: Ülseratif kolitli hastalarda 5. ve 24. saatlerdeki intestinal permeabilite değerleri kontrol grubuna göre anlamlı derecede yüksekti (5 h: üls kol 2.93 ± 2.32; kontrol 0.49 ± 0.47; p= 0.012/24 h: üls kol 7.00 ± 5.03; kontrol 1.27 ± 1.03; p= 0.011). Crohn hastalığında da hasta sayısı az olmasına rağmen intestinal permeabilite de artış görüldü. Ülseratif kolit' de hastalığın aktivitesi ile intestinal permeabilite arasında anlamlı bir korelasyon bulundu (r=0.65; p=0.0006). Sonuç:İntestinal permeabilitenin değerlendiril-mesinde $^51$CrEDTA' nın oral olarak verilmesi basit ve non-invasive bir metodtur. $^51$CrEDTA' nın idrar ile atılımı, hem kalın hemde ince barsakta permeabilitenin arttığını yansıtır ve hastalığın aktivitesi ile de ilişkilidir.
