Clostridium difficile infection in Polish pediatric outpatients with inflammatory bowel disease

The prevalence of Clostridium difficile infection (CDI) in pediatric patients with inflammatory bowel disease (IBD) is still not sufficiently recognized. We assessed the prevalence of CDI and recurrences in outpatients with IBD. In addition, the influence of IBD therapy on CDI and antimicrobial susceptibility of the potentially causative C. difficile strains was assessed. This was a prospective, single-center, observational study. All specimens were obtained between January 2005 and January 2007 from the IBD outpatient service and screened for C. difficile and its toxins. C. difficile isolates were genotyped by PCR ribotyping. Diagnosis of Crohn’s disease (CD) and ulcerative colitis (UC) was based on Porto criteria. Severity of disease was assessed using the Hyams scale (for Crohn’s disease) and the Truelove–Witts scale (for ulcerative colitis). One hundred and forty-three fecal samples from 58 pediatric IBD patients (21 with Crohn’s disease and 37 with ulcerative colitis) were screened. The risk of C. difficile infection was 60% and was independent of disease type (CD or UC) (χ2 = 2.5821, df = 3, p = 0.4606). About 17% of pediatric IBD patients experienced a recurrence of CDI. All C. difficile strains were susceptible to metronidazole, vancomycin and rifampin. A high prevalence of C. difficile infection and recurrences in pediatric outpatients with IBD was observed, independent of disease type. There was no significant correlation between C. difficile infection and IBD therapy. PCR ribotyping revealed C. difficile re-infection and relapses during episodes of IBD in pediatric outpatients

Improved Medical Treatment and Surgical Surveillance of Children and Adolescents with Ulcerative Colitis in the United Kingdom

Inflammatory Bowel Diseases: izy042-izy042. is available online at:https://doi.org/10.1093/ibd/izy042Background: Pediatric ulcerative colitis (UC) presents at an earlier age and increasing prevalence. Our aim was to examine morbidity, steroid sparing strategies, and surgical outcome in children with active UC. Methods: A national prospective audit was conducted for the inpatient period of all children with UC for medical or surgical treatment in the United Kingdom (UK) over 1 year. Thirty-two participating centers recruited 224 children in 298 admissions, comparisons over 6 years were made with previous audits. Results: Over 6 years, recording of Paediatric Ulcerative Colitis Activity Index (PUCAI) score (median 65)(23% to 55%, P < 0.001), guidelines for acute severe colitis (43% to 77%, P < 0.04), and ileal pouch surgery registration (4% to 56%, P < 0.001) have increased. Corticosteroids were given in 183/298 episodes (61%) with 61/183 (33%) not responding and requiring second line therapy or surgery. Of those treated with anti-TNFalpha (16/61, 26%), 3/16 (18.8%) failed to respond and required colectomy. Prescription of rescue therapy (26% to 49%, P = 0.04) and proportion of anti-TNFalpha (20% to 53%, P = 0.03) had increased, colectomy rate (23.7% to 15%) was not significantly reduced (P = 0.5). Subtotal colectomy was the most common surgery performed (n = 40), and surgical complications from all procedures occurred in 33%. In 215/224 (96%) iron deficiency anemia was detected and in 51% treated, orally (50.2%) or intravenously (49.8%). Conclusions: A third of children were not responsive to steroids, and a quarter of these were treated with anti-TNFalpha. Colectomy was required in 41/298 (13.7%) of all admissions. Our national audit program indicates effectiveness of actions taken to reduce steroid dependency, surgery, and iron deficiency. 10.1093/ibd/izy042_video1izy042.video15769503407001.Dr Richard K Russell is supported by an NHS Scotland Research Senior fellowship.
