摘要
A study was performed to investigate whether acute reservoir ileitis (pouchitis) is associated with specific changes in mucosal morphology, crypt cell kinetics and faecal bacteriology in the ileal pouch. Forty-six patients were studied (ileal reservoir, 36; end ileostomy, ten) using clinical grading, sigmoidoscopy and biopsy; 24 patients with a reservoir were restudied after therapy for 1 month with metronidazole 400 mg three times daily. An index of villus atrophy and crypt cell production rate (CCPR) were determined in all biopsy material. Faecal bacteriology was assessed in 12 patients with a pouch before and after metronidazole therapy. The mucosa of patients with pouchitis was associated with a lower villus atrophy index (P = 0.052), a higher CCPR (P = 0.03) and a higher grade of acute inflammation than that in those without pouchitis. There was no difference in faecal bacterial counts between patients with and without pouchitis. A low atrophy index correlated with a high CCPR (P < 0.001), worse functional score (P < 0.001) and more severe pouch mucosal acute inflammation (P < 0.001), but not with faecal bacteriology. Following metronidazole therapy there was resolution of acute pouch inflammation, increased villus atrophy index (P = 0.049), decreased CCPR (P = 0.049) but no differences in faecal bacterial counts apart from Bacteroides species. These data show that metronidazole therapy does not specifically alter the growth of common faecal bacteria in patients with pouchitis, apart from Bacteroides species. However, metronidazole causes resolution of the typical changes in pouch mucosal morphology and crypt cell kinetics associated with pouchitis.
