Prevalence of Clostridioides difficile Infection After Ileal Pouch-anal Anastomosis in Patients With Chronic Antibiotic-dependent Pouchitis and Crohn's-like Disease of the Pouch. Inflamm Bowel Dis 2022:6651945.

Abstract
BACKGROUND Recurrent or chronic antibiotic therapy is a therapeutic hallmark of chronic antibiotic-dependent pouchitis (CADP) or Crohn's-like disease of the pouch. Antibiotics alter the gut microbiome, which may increase the risk of Clostridioides difficile infection (CDI). The aim of this study was to determine the prevalence of CDI in patients with CADP and Crohn's-like disease of the pouch. METHODS We conducted a retrospective cohort study of patients with CADP or Crohn's-like disease of the pouch at a tertiary academic medical center. The primary outcome was prevalence of CDI. Secondary outcomes included antibiotic therapy at the time of CDI diagnosis, treatment regimens for CDI, and subsequent outcomes. RESULTS Overall, 18 of 198 (9.1%) included patients developed CDI. Treatment with antibiotics at the time of CDI diagnosis occurred in 7 of 18 (39%) patients. Preoperative history of CDI was significantly associated with increased risk of developing CDI following ileal pouch anal anastomosis (IPAA) compared with those with no prior history of CDI (12 of 18 [67%] vs 11 of 180 [6%]; P < .001). In 16 of 18 (89%) patients, CDI treatment was initiated with predominantly oral vancomycin (72%) or metronidazole (17%). CONCLUSION Although chronic inflammatory conditions of the pouch arise postoperatively, the prevalence of CDI in this population appears to be similar compared with the general population of patients with inflammatory bowel disease prior to and post IPAA. Preoperative CDI appears to be the greatest risk for postoperative CDI and may require extra vigilance in the assessment of CDI after IPAA.

Endoscopic Phenotype of the J Pouch in Patients With Inflammatory Bowel Disease: A New Classification for Pouch Outcomes. Clin Gastroenterol Hepatol 2022; 20:293-302.e9. [PMID: 33549868 PMCID: PMC8339185 DOI: 10.1016/j.cgh.2021.02.010] [Citation(s) in RCA: 28] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 02/02/2021] [Accepted: 02/02/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Pouchitis is a common complication of ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis who have undergone colectomy. Pouchitis has been considered a single entity despite a broad array of clinical and endoscopic patterns. We developed a novel classification system based on the pattern of inflammation observed in pouches and evaluated the contributing factors and prognosis of each phenotype. METHODS We identified 426 patients (384 with ulcerative colitis) treated with proctocolectomy and IPAA who subsequently underwent pouchoscopies at the University of Chicago between June 1997 and December 2019. We retrospectively reviewed 1359 pouchoscopies and classified them into 7 main pouch phenotypes: (1) normal, (2) afferent limb involvement, (3) inlet involvement, (4) diffuse, (5) focal inflammation of the pouch body, (6) cuffitis, and (7) pouch with fistulas noted 6 months after ileostomy takedown. Logistic regression analysis was used to assess factors contributing to each phenotype. Pouch survival was estimated by the log-rank test and the Cox proportional hazards model. RESULTS Significant contributing factors for afferent limb involvement were a body mass index of 25 or higher and hand-sewn anastomosis, for inlet involvement the significant contributing factor was male sex; for diffuse inflammation the significant contributing factors were extensive colitis and preoperative use of anti-tumor necrosis factor drugs, for cuffitis the significant contributing factors were stapled anastomosis and preoperative Clostridioides difficile infection. Inlet stenosis, diffuse inflammation, and cuffitis significantly increased the risk of pouch excision. Diffuse inflammation was associated independently with pouch excision (hazard ratio, 2.69; 95% CI, 1.34-5.41; P = .005). CONCLUSIONS We describe 7 unique IPAA phenotypes with different contributing factors and outcomes, and propose a new classification system for pouch management and future interventional studies.

Abstract
Pouchitis, Crohn's disease of the pouch, cuffitis, polyps, and extraintestinal manifestations of inflammatory bowel disease are common inflammatory disorders of the ileal pouch. Acute pouchitis is treated with oral antibiotics and chronic pouchitis often requires anti-inflammatory therapy, including the use of biologics. Aetiological factors for secondary pouchitis should be evaluated and managed accordingly. Crohn's disease of the pouch is usually treated with biologics and its stricturing and fistulising complications can be treated with endoscopy or surgery. The underlying cause of cuffitis determines treatment strategies. Endoscopic polypectomy is recommended for large, symptomatic inflammatory polyps and polyps in the cuff. The management principles of extraintestinal manifestations of inflammatory bowel disease in patients with pouches are similar to those in patients without pouches.

Abstract
Introduction The true incidence of Clostridioides difficile infection (CDI) in patients with an ileal pouch is unknown, and there is little published on its associated risk factors. Objective We aimed to evaluate the rate and risk factors of CDI in pouch patients. Methods This was a retrospective review conducted at a single tertiary care inflammatory bowel disease (IBD) center. All ulcerative colitis or IBD-unspecified (IBD-U) patients who underwent total proctocolectomy with ileal pouch anal anastomosis for medically refractory disease or dysplasia between 2008 and 2017 were identified. Symptomatic patients tested for CDI were included. Demographic, disease, and surgical characteristics were collected. Nonparametric methods were used to compare continuous outcomes, and χ<sup>2</sup> and Fisher's exact tests were used to compare patients with and without CDI as appropriate. Results A total of 154 pouch patients had postoperative C. difficilestool testing for symptoms of fever, urgency, increased stool frequency, hematochezia, incontinence, and abdominal and/or pelvic pain. CDI was diagnosed in 11 (7.1%) patients a median of 139 days (IQR 34-1,170) after the final surgical stage. Ten patients (90.9%) received oral vancomycin for 10 days and 1 patient (9.1%) received oral metronidazole for 2 weeks. Ten patients (90.9%) reported improvement in symptoms at completion of therapy. Nine patients (81.8%) were retested for CDI for recurrent symptoms and found to be negative. No patient had CDI recurrence. There was no significant difference in demographic and surgical characteristics, previous antibiotic or proton pump inhibitor use, or previous hospital admission among the patients with and without CDI. Conclusions CDI is a rare cause of infectious pouchitis and treatment with oral vancomycin improves symptoms.

Abstract
BACKGROUND Clostridium difficile infection (CDI) is one of the leading causes of health-care-associated infections in the USA. There are limited data available regarding CDI in hospitalized patients with inflammatory bowel disease-related ileal pouch. AIMS This study aimed to evaluate the demographics, clinical features, risk factors, and admission outcomes among hospitalized patients with CDI-related pouchitis (CDP). METHODS Retrospective chart review was performed for patients who were admitted to our institute for pouchitis between 2013 and 2016 to identify patients with CDP. Logistic regression analysis was performed to assess the risk factors associated with CDP. RESULTS A total of 160 subjects with pouchitis had a total of 218 admissions during the study period. Primary admission diagnosis was pouchitis or inflammatory bowel disease flare-up for 202 (93%) admissions. Clostridium difficile was tested at least once for 72 patients, and the diagnosis of CDP was established for 16 (10%) patients. All patients with CDP were symptomatic, 13 (81%) had diarrhea, 8 (50%) had abdominal pain, 7 (44%) had nausea/vomiting, and 2 (13%) had gastrointestinal bleeding. On multivariable analysis, only body mass index > 25 (OR 0.25, 95% CI 0.06-0.94, p = 0.048) was significantly associated with decreased risk of CDP. No patients in CDP cohort were admitted to ICU, died at the hospital, or readmitted in 30 days after the discharge. CONCLUSIONS In our cohort, obesity was associated with low risk of CDP among hospitalized patients with pouchitis. This finding warrants further validation in prospective studies.

Abstract
BACKGROUND In symptomatic patients with an ileal pouch, stool studies are often sent to diagnose enteric pathogens. Aim of this study is to find the value of routine stool studies in the evaluation of symptomatic patients and the clinical implications of such pathogens in patients with ileal pouches. METHODS Consecutive ileal pouch-anal anastomosis (IPAA) patients who had stool tests out of a 2283-case registry from 2002 to 2015 were included in the study. Patients with positive stool cultures were compared with controls (symptomatic without positive stool culture) in a 1:4 ratio. Response to antibiotic therapy, recurrence rate and rate of hospitalization at 1 and 3 months were assessed. RESULTS A total of 643 (28%) had stool cultures done and only 1.7% (11/643) were found to be positive for stool cultures. Campylobacter spp. (45%) was the most common pathogen followed by Aeromonas spp. (36%). Non-smokers and patients without any antibiotic use in the last 3 months were found to have higher prevalence of positive stool cultures than controls (p < 0.001 and p = 0.023). Patients with pathogenic bacteria were found to have a higher risk of acute kidney injury (27.3% vs 4.5%, p = 0.049), hospitalization within 3 months of initial stool testing (36.4% vs 6.8%, p = 0.009) and mortality (18.2% vs 0%, p = 0.040). However, there were no statistically significant differences in the clinical outcomes in patients with positive stool cultures who received pathogen-directed therapy. CONCLUSIONS We found that the yield of stool tests for bacterial pathogens in symptomatic pouch patients was extremely low and the treatment of detected pathogens had a minimum impact on the disease course of pouchitis. The clinical utility of routine stool culture in those patients warrants further study.

Abstract
BACKGROUND Clostridium difficile infection (CDI) in patients with the ileal pouch after proctocolectomy has been increasingly recognized. We sought to evaluate the frequency and risk factors of CDI in patients with the primary or secondary discharge diagnosis of pouchitis in the United States. METHODS We reviewed the National Inpatient Sample of the Healthcare Cost and Utilization Project and identified patients admitted for pouchitis with underlying inflammatory bowel disease (IBD) or familial adenomatous polyposis (FAP), between 2010 and 2012. Cases with CDI were identified based on a concomitant primary or secondary discharge diagnosis for CDI. The frequency of CDI was estimated in patients with underlying IBD and FAP. Multivariable analysis was conducted to study the risk factors associated with CDI in those with pouchitis with underlying IBD. RESULTS A total of 3566 eligible patients with pouchitis were identified during the study period. Eighty-nine patients (2.5%) had CDI as a concomitant primary or secondary discharge diagnosis. CDI was identified in 2.6% (99.9% confidence interval [CI], 1.3-3.8) of pouchitis patients with underling IBD. None of the patients with pouchitis with underlying FAP were found to have CDI during the study period. Among pouchitis patients with underlying IBD, the presence of nonalcoholic fatty liver disease (odds ratio = 5.4; 95% CI, 1.5-19.9), obesity (odds ratio = 5.5; 95% CI, 1.4-21.4), or obstructive sleep apnea (odds ratio = 10.3; CI, 2.0-53.7) was associated with an increased risk of CDI. CONCLUSIONS It seems that CDI was limited to pouchitis with underlying IBD and rare in those with underlying FAP. Patients with nonalcoholic fatty liver disease, obesity, and obstructive sleep apnea are at an increased risk of C. difficile pouchitis among patients with IBD.

Abstract
BACKGROUND A total proctocolectomy followed by ileal pouch-anal anastomosis is a potentially curative surgery for ulcerative colitis or familial adenomatous polyposis. About 5-35% of patients with ulcerative colitis and 0-11% of patients with familial adenomatous polyposis develop subsequent inflammation of the ileal pouch termed pouchitis. AIM To provide a comprehensive analysis of the research studying the possible pathogenesis of pouchitis. The goals were to identify promising areas of investigation, to help focus clinicians, researchers and patients on how to better understand and then potentially manage ileal pouchitis, and to provide avenues for future research investigations. METHODS This review examined manuscripts from 1981 to 2015 that discussed and/or proposed hypotheses with supportive evidence for the potential underlying pathogenic mechanism for pouchitis. RESULTS The pathogenesis of pouchitis is not definitively understood, but various hypotheses have been proposed, including (i) recurrence of ulcerative colitis, (ii) dysbiosis of the ileal pouch microbiota, (iii) deprivation of nutritional short-chain fatty acids, (iv) mucosal ischaemia and oxygen-free radical injury, (v) host genetic susceptibility and (vi) immune dysregulation. However, none of these alone are able to fully explain pouchitis pathogenesis. CONCLUSIONS Pouchitis, similar to inflammatory bowel disease, is a complex disorder that is not caused by any one single factor. More likely, pouchitis occurs through a combination of both dysregulated host inflammatory mechanisms and interaction with luminal microbiota.

Abstract
BACKGROUND Ulcerative colitis is frequently treated with total proctocolectomy and ileal pouch-anal anastomosis reconstruction. Causes of pouch failure and criteria for improved patient selection remain poorly understood. We aimed to identify risk factors for pouch failure. METHODS We performed a retrospective chart review of patients in a prospectively maintained database. Consecutive patients undergoing ileal pouch-anal anastomosis for inflammatory bowel disease between 2000 and 2010 at our institution were included. The primary outcome was pouch failure, defined as permanent ostomy diversion or pouch excision. RESULTS Of 417 total patients, 28 (6.7%) patients developed pouch failure. Pouch failure was associated with female gender, anastomotic leak, Crohn's disease of the pouch and preoperative Clostridium difficile colitis. The use of anti-tumor necrosis factor alpha biologics was not associated with pouch failure. Notably, 14.9% of patients were diagnosed with preoperative C. difficile colitis, a factor independently associated with pouch failure (hazard ratio 3.02; 95% confidence interval, 1.23-7.44; P = 0.016). C. difficile colitis did not contribute to failure by increasing the incidence of anastomotic leak but was associated with a diagnosis of Crohn's disease of the pouch (adjusted hazard ratio 2.27 [1.08-4.79]; P = 0.031). Anastomotic leak (P < 0.001) and pelvic abscess requiring drainage (P = 0.031) were other independent risk factors for pouch failure. CONCLUSIONS In addition to previously known risk factors, history of preoperative C. difficile colitis was associated with pouch failure after reconstruction, suggesting the need for further study into the role of the gut-associated microbiome in pouch outcomes.

Abstract
Clostridium difficile infection (CDI) after total colectomy has been increasingly recognized over the past decade. C. difficile enteritis (CDE) is a rare occurrence, whereas C. difficile pouchitis (CDP) has been reported in approximately 10% of symptomatic patients seen at a referral center for pouch dysfunction. Similar to colonic CDI in the general population, antibiotic use and comorbid diseases may be risk factors for CDE. In contrast, the postoperative use of antibiotics does not seem to be associated with CDP, whereas male gender, recent hospitalization, and presurgery antibiotic use were shown to be risk factors for CDP. C. difficile is capable of colonizing all intestinal sites, including the ileal pouch. Similarities with the colon at physiological and cellular levels may contribute to the susceptibility of the ileal pouch to CDI. Postcolectomy CDI likely represents a disease spectrum from asymptomatic colonization to severe symptomatic infection. CDI should be considered in ostomy patients with fever and increased ileostomy output and in ileal pouch patients with a change in "normal" symptom pattern or chronic antibiotic-refractory pouchitis. Sensitive and specific methods for detection of CDI are available, and endoscopy is useful in evaluating the patient with suspected CDE or CDP, although pseudomembranes are typically absent. Vancomycin is used as the first-line therapy for CDP and may be warranted for patients with inflammatory bowel disease with CDE. Fecal microbiota transplantation has found its use in the management of severe or antibiotic refractory CDP, but this approach requires evaluation for the management of refractory CDE.

Abstract
BACKGROUND The incidence and virulence of Clostridium difficile infection (CDI) are on the rise. The characteristics of patients who develop CDI following colorectal resection have been infrequently studied. MATERIALS AND METHODS We utilized the University HealthSystem Consortium database to identify adult patients undergoing colorectal surgery between 2008 and 2012. We examined the patient-related risk factors for CDI and 30-day outcomes related to its occurrence. RESULTS A total of 84,648 patients met our inclusion criteria, of which the average age was 60 years and 50% were female. CDI occurred in 1,266 (1.5%) patients during the years under study. The strongest predictors of CDI were emergent procedure, inflammatory bowel disease (IBD), and major/extreme APR-DRG severity of illness score. CDI was associated with a higher rate of complications, intensive care unit (ICU) admission, longer preoperative inpatient stay, 30-day readmission rate, and death within 30 days compared to non-CDI patients. Cost of the index stay was, on average, $14,130 higher for CDI patients compared with non-CDI patients. CONCLUSION Emergent procedures, higher severity of illness, and inflammatory bowel disease are significant risk factors for postoperative CDI in patients undergoing colorectal surgery. Once established, CDI is associated with worse outcomes and higher costs. The poor outcomes of these patients and increased costs highlight the importance of prevention strategies targeting high-risk patients.
