    Notes: Abstract PURPOSE: This study was undertaken to assess the electron microscopic and microbiologic findings in tissue biopsy samples from patients with pouchitis and to compare them with findings in patients with normal pouches, conventional ileostomies, and normal ileum. METHODS: Tissue samples were obtained from 78 patients: 23 patients with normal pouches endoscopically and histologically (Group 1), 12 patients with endoscopic and histologic evidence of inflammation (pouchitis) (Group 2), 14 patients who had either endoscopic or histologic evidence of inflammation but not both (Group 3), 20 patients with conventional ileostomies (Group 4), and 9 patients without ileostomies from whom biopsy samples of normal ileum were obtained (Group 5). RESULTS: The mean total aerobic facultative counts in the biopsy samples from the pouchitis patients were significantly higher when compared with biopsy samples from Groups 4 and 5 ( P 〈0.05). There were no significant differences in the mean anaerobic counts among the five groups. Positive cultures were obtained in 90 percent of patients with pouches compared with 69 percent of patients with conventional ileostomies or normal ileum ( P 〈0.05). Intramural bacteria were observed on electron microscopy in biopsy specimens of 47 percent patients with pouches compared with 14 percent of patients with conventional ileostomies or normal ileum ( P 〈0.05). However, the proportion of patients with positive cultures or intramural bacteria was not increased in the pouchitis group compared with the normal pouch group. CONCLUSION: These data suggest that intramural aerobic facultative bacterial counts are elevated in patients with pouchitis and may play a role in the pathogenesis of pouchitis.

    Notes: Abstract Seventy-eight pregnancies in 50 patients were reviewed to evaluate the effects of Crohn's disease on the outcome of pregnancy and the influence of the pregnancy on the course of Crohn's disease. Overall, 21 pregnancies (27 percent) had abnormal outcomes including spontaneous abortions (9), infants small for gestational age (6), premature infants (5), and infants who developed respiratory distress (1). Eight (50 percent) patients with active disease compared with 13 (21 percent) patients with inactive disease at conception had abnormal outcomes (P 〈0.05). During pregnancy 15 (55 percent) with active disease and 6 (12 percent) with inactive disease had an abnormal outcome (P 〈0.001). Neither medical nor surgical treatment, independent of disease activity, appeared to affect the outcome adversely. Eighteen of 73 (25 percent) patients with quiescent or mild disease relapsed, and seven of 16 patients with some disease activity improved (44 percent). Of 34 patients on medication, nine relapsed (27 percent), and of 39 patients not on medication, nine relapsed (24 percent) (P=N.S.). These results suggest that the outcome of pregnancy is not adversely affected by Crohn's disease. However, patients with active disease at conception and/or during the pregnancy have poorer outcomes independent of the use of medication or requirement of surgery. Neither pregnancy nor medications taken affect the course of the disease.
