Ileal pouch–anal anastomosis (IPAA) has become the surgical procedure of choice for patients with chronic ulcerative colitis. No study to date has examined functional and quality-of-life outcomes 30 years after pouch construction.MethodsUsing data from a prospectively maintained database with annually distributed questionnaires, functional outcomes, pouch complications, and quality of life after IPAA were determined.ResultsOverall, 93.3% of patients had a functioning pouch at 30 years. Stool frequency during the day increased slightly from a mean of 5.7 (SD, 2.3) at 1 year to 6.2 (SD, 2.9) at 30 years (P < 0.001); nighttime frequency also increased slightly from 1.5 (SD, 1.2) to 2.1 (SD, 1.2) (P < 0.001). Pouch outcomes and stool frequency were significantly associated with diagnosis, being worse in patients with Crohn's disease, but were minimally associated with age greater than 65 years. After IPAA, the 30-year cumulative probability of pouchitis, stricture, obstruction, and fistula were 80.2%, 56.7%, 44.0%, and 15.8%, respectively. Quality of life scores remained stable over the 30 years.ConclusionsIPAA is a durable operation for patients requiring proctocolectomy for chronic ulcerative colitis and indeterminate colitis. The functional outcomes and quality of life remained relatively unchanged over the 30 years after IPAA underscoring the longevity of pouches.

BACKGROUNDHyperbaric oxygen therapy (HBOT) markedly increases tissue oxygen delivery. Case series suggest it may have a potential therapeutic benefit in ulcerative colitis (UC). We investigated the therapeutic potential of HBOT as an adjunct to steroids for UC flares requiring hospitalization.METHODSThe study was terminated early due to poor recruitment with 18 of the planned 70 patients enrolled. UC patients hospitalized for moderate–severe flares (Mayo score ≥6, endoscopic sub-score ≥2) were block randomized to steroids + daily HBOT (n = 10) or steroids + daily sham hyperbaric air (n = 8). Patients were blinded to study assignment, and assessments were performed by a blinded gastroenterologist. Primary outcome was the clinical remission rate at study day 5 (partial Mayo score ≤2 with no sub-score >1). Key secondary outcomes were: clinical response (reduction in partial Mayo score ≥2, rectal bleeding sub-score of 0–1) and progression to second-line therapy (colectomy or biologic therapy) during the hospitalization.RESULTSA significantly higher proportion of HBOT-treated patients achieved clinical remission at study day 5 and 10 (50 vs. 0%, p = 0.04). HBOT-treated patients less often required progression to second-line therapy during the hospitalization (10 vs. 63%, p = 0.04). The proportion requiring in-hospital colectomy specifically as second-line therapy for medically refractory UC was lower in the HBOT group compared to sham (0 vs. 38%, p = 0.07). There were no serious adverse events.CONCLUSIONIn this small, proof-of-concept, phase 2A trial, the use of HBOT as an adjunctive therapy to steroids for UC patients hospitalized for moderate–severe flares resulted in higher rates of clinical remission, and a reduction in rates of progression to second-line therapy during the hospitalization. Larger well-powered trials are needed, however, to provided definitive evidence of therapeutic benefit.

Intestinal Barrier Dysfunction in Inflammatory Bowel Disease: Underpinning Pathogenesis and Therapeutics
2023
The intestinal barrier is composed of several essential elements including luminal enzymes, bile acids, water layer, epithelial layer, and enterocyte layer. It acts as a dynamic interface between the luminal contents of food, commensal and pathogenic bacteria, and the gastrointestinal tract. The role of barrier dysfunction is of significant research interest in the development and targeted treatment of chronic inflammatory gastrointestinal conditions, such as inflammatory bowel disease. This review aims to examine the role of intestinal barrier dysfunction in the development of inflammatory bowel disease, the pathophysiology of increased barrier permeability in inflammatory bowel disease, and to explore potential treatment targets and clinical applications.

Limited guidance exists for the postdischarge care of patients with ulcerative colitis hospitalized for moderate-severe flares.
RAND methodology was used to establish appropriateness of inpatient and postdischarge steroid dosing, discharge criteria, follow-up, and postdischarge biologic or small molecule initiation. A literature review informed on the panel's voting, which occurred anonymously during 2 rounds before and after a moderated virtual session.
Methylprednisolone 40-60 mg intravenous every 24 hours or hydrocortisone 100 mg intravenous 3 times daily is appropriate for inpatient management, with methylprednisolone 40 mg being appropriate if intolerant of higher doses. It is appropriate to discharge patients once rectal bleeding has resolved (Mayo subscore 0-1) and/or stool frequency has returned to baseline frequency and form (Mayo subscore 0-1). It is appropriate to discharge patients on 40 mg of prednisone after observing patients for 24 hours in hospital to ensure stability before discharge. For patients being discharged on steroids without in-hospital biologic or small molecule therapy initiation, it is appropriate to start antitumor necrosis factor (TNF) therapy after discharge for anti-TNF-naive patients. For anti-TNF-exposed patients, it is appropriate to start vedolizumab or ustekinumab for all patients and tofacitinib for those with a low risk of adverse events. It is appropriate to follow up patients clinically within 2 weeks and with lower endoscopy within 4-6 months after discharge.
We provide recommendations on the inpatient and postdischarge management of patients with ulcerative colitis hospitalized for moderate-severe flares.

Total abdominal proctocolectomy with ileal pouch–anal anastomosis (IPAA) for ulcerative colitis (UC) is associated with substantial complications despite the benefits of managing refractory and/or neoplasia-associated disease. For the purpose of this review, we focused on the diagnosis of some of the most common inflammatory and structural pouch disorders and their respective management. Pouchitis is the most common complication, and it is typically responsive to antibiotics. However, chronic antibiotic refractory pouchitis (CARP) has been increasingly recognized, and biologic therapies have emerged as the mainstay of therapy. Crohn's-like disease of the pouch (CLDP) can affect up to 10% of patients with UC after IPAA. Medical options are similar to CARP therapies, including biologics with immunomodulators. Studies have shown higher efficacy rates of biologics for CLDP when compared with those for CARP. In addition, managing stricturing and fistulizing CLDP is challenging and often requires interventional endoscopy (balloon dilation and/or stricturotomy) and/or surgery. The implementation of standardized diagnostic criteria for inflammatory pouch disorders will help in advancing future therapeutic options. Structural pouch disorders are commonly related to surgical complications after IPAA. We focused on the diagnosis and management of anastomotic leaks, strictures, and floppy pouch complex. Anastomotic leaks and anastomotic strictures occur in approximately 15% and 11% of patients with UC after IPAA, respectively. Further complications from pouch leaks include the development of sinuses, fistulas, and pouch sepsis requiring excision. Novel endoscopic interventions and less invasive surgical procedures have emerged as options for the management of these disorders.

An Update on the Medical Management of Inflammatory Pouch Complications
2020
Total proctocolectomy with ileal pouch-anal anastomosis is the surgical procedure of choice for patients with medically-refractory ulcerative colitis or ulcerative colitis with associated dysplasia. Although most patients after ileal pouch-anal anastomosis experience good functional outcomes, a number of complications may develop. Of the long-term complications, pouchitis is most common. Although most respond to antibiotic treatment, some patients develop chronic pouchitis, leading to substantial morbidity and occasionally pouch failure. In patients with pouchitis who are not responsive to conventional antimicrobial therapy, secondary causes of chronic pouchitis need to be considered, including Crohn's disease of the pouch. In recent years, more literature has become available regarding the medical management of chronic pouchitis and Crohn's disease of the pouch, including the use of newer biologic agents. We herein provide a concise review on inflammatory complications involving the ileal pouch, including a focused approach to diagnosis and medical management.

Objectives:Depression is prevalent in inflammatory bowel disease (IBD) patients. The impact of depression on IBD is not well-studied. It is unknown how providers should assess depression.Methods:We used data from the Sinai-Helmsley Alliance for Research Excellence cohort, to assess methods of diagnosing depression and effects of baseline depression on disease activity at follow-up. A patient health questionnaire (PHQ-8) score ≥5 was consistent with mild depression. Relapse was defined as a modified Harvey-Bradshaw Index ≥5 or Simple Clinical Colitis Activity Index >2. We performed binomial regression to calculate adjusted risk ratios (RRs).Results:We included 2,798 Crohn's disease (CD) patients with 22-month mean follow-up and 1,516 ulcerative colitis (UC) patients with 24-month mean follow-up. A total of 64% of CD patients and 45% of UC patients were in remission at baseline. By self-report, 20% of CD and 14% of UC patients were depressed. By PHQ-8, 38% of CD and 32% of UC patients were depressed (P<0.01). Adjusted for sex, remission, and disease activity, CD patients with baseline depression were at an increased risk for relapse (RR: 2.3; 95% confidence interval (CI): 1.9-2.8), surgery, or hospitalization (RR: 1.3 95% CI: 1.1-1.6) at follow-up. UC patients with baseline depression were also at increased risk for relapse (RR: 1.3; 95% CI: 0.9-1.7), surgery, or hospitalization (RR: 1.3; 95% CI: 1.1-1.5) at follow-up.Conclusions:Baseline depression is associated with a higher risk for aggressive IBD at follow-up. A single question is not a sensitive method of assessing depression. Providers should consider administering the PHQ-8 to capture those at greater risk for aggressive disease.

Accountability
2024
Within the Department of Medicine (DOM) in a large tertiary academic health care facility in midwestern United States, we have developed an educational offering that incorporates an academic writing program (AWP) blending the approaches of a writing accountability work group, a writing workshop, and didactic writing courses. The purpose of this AWP was to assist healthcare professionals (HCP) with their manuscript writing skills to enhance academic productivity. We report our evolving journey and experiences with this AWP. To date, it has been offered 3 times to 25 HCP over the course of 3 years. Among those responding to a post program follow up survey (N = 11), 8 (73%) indicated that they completed the project that they were working on during the AWP and went on to publish the manuscript (N = 5) or were in the process of submission (N = 2). Some indicated they has also gone on to present posters (N = 2) or were in the process of presenting posters (N = 2) or had received grants (N = 1) or were awaiting grant notice (N = 1). A number of attendees have continued to use and share the tools presented during the AWP. Based on input from attendees and increased requests for this AWP, this educational program has been deemed a success and expansion of this program is currently underway.

BackgroundForty distinct primary sclerosing cholangitis (PSC) genomic loci have been identified through multiancestry meta-analyses. The polygenic risk score (PRS) could serve as a promising tool to discover unique disease behaviour, like PSC, underlying inflammatory bowel disease (IBD).AimTo test whether PRS indicates PSC risk in patients with IBD.Materials and methodsMayo Clinic and Washington University at St Louis IBD cohorts were used to test our hypothesis. PRS was modelled through the published PSC loci and weighted with their corresponding effect size. Logistic regression was applied to predict the PSC risk.ResultsIn total, 63 (5.6%) among 1130 patients with IBD of European ancestry had PSC. Among 381 ulcerative colitis (UC), 12% had PSC; in contrast to 1.4% in 761 Crohn disease (CD). Compared with IBD alone, IBD-PSC had significantly higher PRS (PSC risk: 3.0% at the lowest PRS quartile vs 7.2% at the highest PRS quartile, Ptrend =.03). In IBD subphenotypes subgroup analysis, multivariate analysis shows that UC-PSC is associated with more extensive UC disease (OR, 5.60; p=0.002) and younger age at diagnosis (p=0.02). In CD, multivariate analysis suggests that CD-PSC is associated with colorectal cancer (OR, 50; p=0.005).ConclusionsWe found evidence that patients with IBD with PSC presented with a clinical course difference from that of patients with IBD alone. PRS can influence PSC risk in patients with IBD. Once validated in an independent cohort, this may help identify patients with the highest likelihood of developing PSC.
