Background and Goals: Ulcerative colitis (UC) readmissions to the hospital pose a burden to patients and health care systems. Preventing readmissions is important for the quality of care and quality of life of patients with UC. We aimed to identify the incidence of 30 and 90-day readmissions and its predictors in patients with UC. Study: Retrospective review of the 2018 National Readmission Database (NRD) of adult patients readmitted after an index admission (IA) of UC. ICD-10CM/PCS codes were used to identify patients with UC, other comorbidities, and procedures. We identified the most common causes for readmission and independent risk factors for readmission were identified using Cox regression analysis. Results: The 30 and 90-day readmission rates for UC in 2018 were 16.6% and 28.3%. In-hospital mortality and mean length of stay were higher in patients readmitted within both 30 and 90 days. Independent predictors of 30-day readmission were higher Charlson Comorbidity Index (CCI), undergoing ileostomy, increasing length of stay, malnutrition and opioid use disorder at IA. In the 90-day readmission cohort, independent predictors were CCI score of 2 or ≥3, developing shock, admission to large bed size hospitals, undergoing colectomy, increasing length of stay and opioid use disorder at IA. The number one readmission cause at 30 and 90 days was sepsis of unspecified organism. Conclusion: Readmission is associated with higher mortality and is associated with risk factors such as malnutrition, undergoing ileostomy during IA and opioid use disorder. Readmissions in UC continue to pose a high burden to patients and our health care system.

Abstract Background Patients with inflammatory bowel disease (IBD) are at increased risk of herpes zoster (HZ) infection due to innate immune abnormalities and use of immunosuppressive therapy. The recombinant zoster vaccine (RZV) is recommended, but its efficacy in preventing recurrent HZ among patients with IBD is not well established. Methods Using data from the TriNetX Linked Network, we conducted a retrospective cohort study of adults (≥18 years) with IBD and a prior uncomplicated HZ episode. Patients with IBD who received RZV were propensity score-matched 1:1 with those who did not. The primary outcome was subsequent HZ complications. Secondary outcomes included subtypes of HZ complications and recurrent uncomplicated HZ. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated via Cox proportional hazards models. Results After matching, 1260 vaccinated and 1260 unvaccinated patients with IBD were included. Compared to the unvaccinated cohort, patients receiving RZV had a significantly reduced incidence of HZ complications (7.4% vs. 14.5%; HR, 0.75; 95% CI, 0.58–0.97; P = .028). Postherpetic neuralgia was notably decreased (5.8% vs. 12.5%; HR, 0.66; P = .010), and no central nervous system involvement occurred among vaccinated patients. Protective effects were more pronounced in patients with ulcerative colitis, females, and those not receiving immunosuppressive therapy. Conclusions RZV substantially lowers the risk of HZ complications in patients with IBD, offering significant clinical benefits to those at high risk due to immunosuppression. These findings underscore the importance of RZV as part of preventive care strategies in patients with IBD.

Abstract Background Iron deficiency is common in patients with inflammatory bowel disease (IBD), where poor absorption or prior surgery often renders oral iron supplementation ineffective, necessitating intravenous (IV) iron therapy. Hypophosphataemia, particularly associated with ferric carboxymaltose via fibroblast growth factor 23 dysregulation, is a recognized complication of IV iron therapy. It can result in severe outcomes such as rhabdomyolysis, osteomalacia, fractures, and convulsions. This study evaluates the risk of hypophosphataemia between ferric carboxymaltose and other IV iron formulations and its association with complications. Methods This retrospective propensity-matched study utilised the TriNetX database, a global repository of de-identified electronic health records. The first analysis compared ferric carboxymaltose to other IV iron formulations (iron sucrose, sodium ferric gluconate, ferumoxytol, ferric derisomaltose), matched on demographics (age, gender, ethnicity) and comorbidities (vitamin D deficiency, malnutrition, malabsorption, diabetes, CKD by stage, alcohol abuse, hyperparathyroidism, corticosteroid, diuretic, antacid, and bisphosphonate use) to assess hypophosphataemia risk. The second and third analyses evaluated hypophosphataemia-related complications in ferric carboxymaltose versus other formulations, both in the general population and in patients with IBD. Results We compared 115,242 ferric carboxymaltose patients to those on other IV iron formulations. Ferric carboxymaltose was associated with higher odds of severe (OR: 2.84, 2.22–3.64, p<0.0001) and moderate (OR: 1.37, 1.29–1.46, p<0.0001) hypophosphataemia but lower odds of mild hypophosphataemia (OR: 0.84, 0.79–0.88, p<0.0001). Among 25,586 hypophosphataemic patients, those on ferric carboxymaltose had lower odds of acute complications within 3 months, including muscle weakness (OR: 0.57, 0.47–0.70, p<0.0001), rhabdomyolysis (OR: 0.38, 0.20–0.75, p=0.003), disorientation (OR: 0.53, 0.46–0.61, p<0.0001), convulsions (OR: 0.59, 0.48–0.73, p<0.0001), cardiac arrhythmias (OR: 0.61, 0.54–0.69, p<0.0001), and respiratory failure (OR: 0.57, 0.50–0.64, p<0.0001). Over 2 years, chronic complications such as osteomalacia and fractures (23,508 patients each) showed no differences. In patients with IBD, no significant differences were observed in acute (2,688 each) or chronic complications (2,541 each) between cohorts. Conclusion Ferric carboxymaltose was linked to higher odds of severe and moderate hypophosphataemia but fewer acute complications than other IV iron formulations. The reasons for these differences remain unclear and warrant further research to understand the relationship between IV iron, hypophosphataemia, and clinical outcomes.

Background: Video capsule retention is a complication that can have serious consequences in patients with Crohn’s disease (CD). The patency capsule was developed to detect small bowel strictures. The usefulness of patency capsules in patients who do not have evidence of small bowel disease on imaging is uncertain. Study: This is a multicenter retrospective study of patients with suspected or confirmed CD who underwent a patency capsule study between January 2017 and February 2023. We excluded patients who were lost to follow-up or did not have computerized tomography or magnetic resonance imaging of the abdomen within 180 days before or after the patency capsule study. Results: A total of 105 patients met the inclusion criteria with 69% having a confirmed CD diagnosis. The majority of patients (95/105; 90.5%) passed their patency capsule. A total of 91 patients had their subsequent video capsule endoscopy (VCE), with 96.7% (88/91) successfully passing the capsule. Out of those who passed the VCE, 2 patients had patency capsule retention. Both had normal small bowel imaging. Meanwhile, the 3 patients who had VCE retention had evidence of small bowel disease in their imaging scans. The presence of abnormal small bowel wall thickening or stricture on imaging had a statistically significant association with VCE retention (P=0.02). Conclusion: Our study demonstrated a statistically significant association between small bowel disease on imaging and retention of both patency capsules and VCE. Small bowel imaging in patients with suspected or documented CD had a negative predictive value of 100% for VCE retention.

Background: While bariatric surgery may reduce obesity-associated inflammation, alterations in gut microbiome and nutrition could impact inflammatory bowel disease (IBD) risk. This study aimed to investigate the association between bariatric surgery and new onset IBD. Methods: A systematic review and meta-analysis of observational studies was conducted from inception to 31 January 2024. Risk estimates were pooled using a DerSimonian and Laird random-effects model, and adjusted hazards ratios (HRs) with corresponding 95% confidence interval (CI) were reported. The modified Newcastle-Ottawa Quality Assessment Scale (NOS) was used to examine the risk of bias. Results: Of 98 articles screened, four studies comprising 4,727,600 participants were included in the systematic review and two studies in the meta-analysis. Included studies had high quality and low risk of bias according to NOS. The pooled analysis revealed a significant risk of new onset IBD (HR: 1.28, 95% CI: 1.04–1.53, I2 = 74.9%), particularly Crohn’s disease (HR: 1.75, 1.59–1.92, I2 = 0), following bariatric surgery, but no significant risk of ulcerative colitis (HR: 0.93, 0.75–1.11, I2 = 11.5%). Conclusions: This meta-analysis found that bariatric surgery was associated with a higher risk of developing Crohn’s disease. Patients should be counseled on IBD risk pre-surgery, and symptomatic patients should be evaluated post-surgery to enable early diagnosis and management.

ABSTRACT Nintedanib is a medication that has been increasingly used for treatment of idiopathic and progressive pulmonary fibrosis. In this case series, we describe 3 patients with colitis symptoms associated with nintedanib use. Nintedanib discontinuation resulted in symptomatic resolution in all patients. Budesonide decreased symptoms in 1 patient. Clinicians should be vigilant in taking a thorough medication history and include nintedanib as a cause for gastrointestinal symptoms including colitis.

Abstract Background Approximately 15%–20% of patients with ulcerative colitis (UC) will require surgery during their lifetime. Ileal pouch–anal anastomosis (IPAA) is the preferred surgical option, which typically requires access to a specialist experienced in surgery for inflammatory bowel diseases (IBD). Methods The aims of this study are the assessment of the comparative use of IPAA for UC among different racial/ethnic groups and observe trends over the past decade in the United States as well as the comparative assessment of their respective postoperative outcomes. This was an observational retrospective study using the National Inpatient Sample (NIS) 2009–2018 dataset. All patients with ICD-9/10CM codes for UC were included. The primary outcome was comparative trends in IPAA construction across races/ethnicities in the past decade, which was compared to White patients as reference. Multivariate regression analyses were used to adjust for age, gender, Charlson comorbidity index, income in patient zip code, insurance status, hospital region, location, size, and teaching status. Results The number of patients discharged from US hospitals with an associated diagnosis of UC increased between 2009 and 2018, but the number of patients undergoing an IPAA decreased during that time period. Of 1 153 363 admissions related to UC, 60 688 required surgery for UC, of whom 16 601 underwent IPAA in the study period. Of all the patients undergoing surgery for UC, 2862 (4.7%) were Black, while 44 351 were White. This analysis indicated that Black patients were less likely to undergo IPAA both in 2009 and in 2018 compared to Whites. Hispanic patients were significantly less likely to receive IPAA in 2009 but were no longer less likely to receive IPAA in 2018 when compared to Whites. Conclusions The use of IPAA among Black patients requiring surgery for UC remains less common than amongst their White counterparts. Further research is needed to determine if racial disparity is a factor in decreased access to specialized care.
