Differences in Management and Outcomes of Older and Younger Adults with Acute Severe Ulcerative Colitis

BACKGROUND

Older adults with ulcerative colitis [UC] have greater morbidity than younger adults. The goal of this study was to investigate differences in the management and outcomes of older and younger patients hospitalised with severe UC.

METHODS

We conducted a retrospective cohort study of patients hospitalised for acute severe ulcerative colitis requiring intravenous steroids. We compared outcomes of adults aged ≥65 years with outcomes of younger patients. Primary study outcomes included frequency and timing of medical and surgical rescue therapy during the hospitalisation, postoperative complications, frailty, and mortality outcomes up to 1 year following the hospitalisation.

RESULTS

Our cohort included 63 older adults [≥65 years] and 137 younger adults [14-64 years]. Despite similar disease severity at hospitalisation, older adults were half as likely to receive medical rescue therapy (odds ratio 0.45, 95% confidence interval [CI] 0.22-0.91). This difference was more striking among the frailest older adults. Older patients were similarly likely to undergo surgery but were more likely to undergo urgent or emergent procedures [50%] compared with younger patients [13%] [p <0.004]. The fraction of older adults at high risk for frailty increased from 33% pre-hospitalisation to 42% post-hospitalisation. Nearly one-third [27.8%] of older adults died within 1 year of hospitalisation, with half the deaths among older adults being attributable to UC or complications of UC.

CONCLUSIONS

In comparison with younger patients, older adults had lower frequency use of medical rescue therapy, higher rates of emergency surgery, and increased mortality within 1 year. Further research is needed to optimise care pathways in this population.

Prevalence and Appropriateness of Polypharmacy in Older Adults with Inflammatory Bowel Diseases

BACKGROUND

Despite the growing prevalence of older adults with inflammatory bowel diseases (IBD), polypharmacy, an important geriatric construct, is poorly understood. We described polypharmacy and its implications in older adults with IBD.

METHODS

In a cross sectional study of adults ≥ 60 years with IBD, we obtained medication lists from the medical record and patients. We assessed medications by the Beer's criteria, anti-cholinergic burden and drug-drug interactions. We constructed multi-variate logistic regression models to assess association between polypharmacy with low quality-of-life, controlling for age, sex, IBD-type, number of comorbidities and depression.

RESULTS

In 100 adults ≥ 60 years with IBD, with a median age of 68 years, 56% met criteria for remission by a validated disease activity index. Polypharmacy, defined as ≥ 5 concomitant medications, was noted in 86% of the cohort and 45% had severe polypharmacy, defined as ≥ 10 concomitant medications. In this cohort, 48% were on ≥ 1 medication that met Beer's criteria for potentially inappropriate in older adults and 24% had a cumulative anti-cholinergic drug burden score of ≥ 3, the threshold for serious adverse events attributed to anti-cholinergic burden. Serious drug-drug interactions were found in 26% with 7% involving an IBD medication. Controlling for potential confounders, polypharmacy, defined both numerically (OR 22.79, p < 0.01) and by medication appropriateness (OR 1.95, p < 0.01), was significantly associated with low quality of life.

CONCLUSION

Polypharmacy is prevalent in older adults with IBD and independently associated with low quality of life. Describing polypharmacy can guide de-prescription strategies tailored to GI clinic for older adults with IBD.

Oral vs Intravenous Discharge Antibiotic Regimens in the Management of Intra-abdominal Abscesses in Penetrating Crohn's Disease

BACKGROUND

Antibiotics are a cornerstone in management of intra-abdominal abscesses in Crohn's disease (CD). Yet, the optimal route of antibiotic administration is poorly studied. We aimed to compare surgical and nonsurgical readmission outcomes for patients hospitalized for intra-abdominal abscesses from CD discharged on oral (PO) or intravenous (IV) antibiotics.

METHODS

Data for patients with CD hospitalized for an intra-abdominal abscess were obtained from 3 institutions from January 2010 to December 2020. Baseline patient characteristics were obtained. Primary outcomes of interest included need for surgery and hospital readmission within 1 year from hospital discharge. We used multivariable logistic regression models and Cox regression analysis to adjust for abscess size, history of prior surgery, history of penetrating disease, and age.

RESULTS

We identified 99 patients discharged on antibiotics (PO = 74, IV = 25). Readmissions related to CD at 12 months were less likely in the IV group (40% vs 77% PO, P = .01), with the IV group demonstrating a decreased risk for nonsurgical readmissions over time (hazard ratio, 0.376; 95% confidence interval, 0.176-0.802). Requirement for surgery was similar between the groups. There were no differences in time to surgery between groups.

CONCLUSIONS

In this retrospective, multicenter cohort of CD patients with intra-abdominal abscess, surgical outcomes were similar between patients receiving PO vs IV antibiotics at discharge. Patients treated with IV antibiotics demonstrated a decreased risk for nonsurgical readmission. Further prospective trials are needed to better delineate optimal route of antibiotic administration in patients with penetrating CD.

Association of Proton Pump Inhibitor Use With Incident Dementia and Cognitive Decline in Older Adults: A Prospective Cohort Study

BACKGROUND & AIMS

Prior studies have suggested that proton pump inhibitor (PPI) use is associated with increased risk of dementia; however, these have been limited by incomplete assessment of medication use and failure to account for confounders. Furthermore, prior studies have relied on claims-based diagnoses for dementia, which can lead to misclassification. We investigated the associations of PPI and histamine-2 receptor antagonist (H2RA) use with dementia and cognitive decline.

METHODS

We conducted a post hoc analysis of ASPirin in Reducing Events in the Elderly (ASPREE), a randomized trial of aspirin in the United States and Australia, including 18,934 community-based adults ≥65 years of all races/ethnicities. Baseline and recent PPI and H2RA use were determined according to review of medications during annual in-person study visits. Incident dementia was defined according to Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria. Secondary endpoints include cognitive impairment, no dementia (CIND) and changes in cognition. Associations of medication use with dementia and CIND outcomes were examined using Cox proportional hazards models. Changes in cognitive test scores were examined using linear mixed-effects models.

RESULTS

Baseline PPI use vs nonuse was not associated with incident dementia (multivariable hazard ratio, 0.88; 95% confidence interval, 0.72-1.08), CIND (multivariable hazard ratio, 1.00; 95% confidence interval, 0.92-1.09), or with changes in overall cognitive test scores over time (multivariable B, -0.002; standard error, 0.01; P = .85). Similarly, no associations were observed between H2RA use and all cognitive endpoints.

CONCLUSIONS

In adults ≥65 years of age, PPI and H2RA use were not associated with incident dementia, CIND, or decline in cognition over time. These data provide reassurance about the safety of long-term use of PPIs among older adults.

A Narrative Review of Financial Burden, Distress, and Toxicity of Inflammatory Bowel Diseases in the United States

INTRODUCTION

Inflammatory bowel diseases (IBD) affect >3 million Americans and are associated with tremendous economic burden. Direct patient-level financial impacts, financial distress, and financial toxicity are less well understood. We aimed to summarize the literature on patient-level financial burden, distress, and toxicity associated with IBD in the United States.

METHODS

We conducted a literature search of US studies from 2002 to 2022 focused on direct/indirect costs, financial distress, and toxicity for patients with IBD. We abstracted study objectives, design, population characteristics, setting, and results.

RESULTS

Of 2,586 abstracts screened, 18 articles were included. The studies comprised 638,664 patients with IBD from ages 9 to 93 years. Estimates for direct annual costs incurred by patients ranged from $7,824 to $41,829. Outpatient costs ranged from 19% to 45% of direct costs, inpatient costs ranged from 27% to 36%, and pharmacy costs ranged from 7% to 51% of costs. Crohn's disease was associated with higher costs than ulcerative colitis. Estimates for indirect costs varied widely; presenteeism accounted for most indirect costs. Severe and active disease was associated with greater direct and indirect costs. Financial distress was highly prevalent; associated factors included lower education level, lower household income, public insurance, comorbid illnesses, severity of IBD, and food insecurity. Higher degrees of financial distress were associated with greater delays in medical care, cost-related medication nonadherence, and lower health-related quality of life.

DISCUSSION

Financial distress is prevalent among patients with IBD; financial toxicity is not well characterized. Definitions and measures varied widely. Better quantification of patient-level costs and associated impacts is needed to determine avenues for intervention.

Managing the older adult with inflammatory bowel disease: is age just a number?

PURPOSE OF REVIEW

This review summarizes the most recent literature on older adults with inflammatory bowel diseases (IBD). Additionally, we review geriatric syndromes that may be pertinent to the management of older adults with IBD.

RECENT FINDINGS

Traditionally chronological age has been used to risk stratify older adults with IBD, however physiologic status, including comorbidities, frailty, and sarcopenia, are more closely associated with clinical outcomes for older adults. Delaying care for and undertreating older adults with IBD based upon advanced chronologic age alone is associated with worse outcomes, including increased mortality. Treatment decisions should be made considering physiologic status, with an understanding of the differential risks associated with both ongoing disease and treatment. As such, there is an increasing recognition of the impact geriatric syndromes have on older adults with IBD, which need to be further explored.

SUMMARY

Older adults with IBD are less likely to receive advanced therapies and timely surgery. They are also more likely to have adverse outcomes despite having similar disease courses to younger adults with IBD. Focusing on biological age as opposed to chronological age can shift this trajectory and improve quality of care for this growing population of patients with IBD.

Incidence, severity, and mortality of post-ERCP pancreatitis: an updated systematic review and meta-analysis of 145 randomized controlled trials

BACKGROUND AND AIMS

The incidence, severity, and mortality of post-ERCP pancreatitis (PEP) largely remain unknown with changing trends in ERCP use, indication, and techniques. We sought to determine the incidence, severity, and mortality of PEP in consecutive and high-risk patients based on a systemic review and meta-analysis of patients in placebo and no-stent arms of randomized control trials (RCTs).

METHODS

The MEDLINE, Embase, and Cochrane databases were searched from the inception of each database to June 2022 to identify full-text RCTs evaluating PEP prophylaxes. The incidence, severity, and mortality of PEP from the placebo or no-stent arms of RCTs were recorded for consecutive and high-risk patients. A random-effects meta-analysis for a proportions model was used to calculate PEP incidence, severity, and mortality.

RESULTS

One hundred forty-five RCTs were found with 19,038 patients in the placebo or no-stent arms. The overall cumulative incidence of PEP was 10.2% (95% confidence interval [CI], 9.3-11.3), predominantly among the academic centers conducting such RCTs. The cumulative incidences of severe PEP and mortality were .5% (95% CI, .3-.7) and .2% (95% CI, .08-.3), respectively, across 91 RCTs with 14,441 patients. The cumulative incidences of PEP and severe PEP were 14.1% (95% CI, 11.5-17.2) and .8% (95% CI, .4-1.6), respectively, with a mortality rate of .2% (95% CI, 0-.3) across 35 RCTs with 3733 patients at high risk of PEP. The overall trend for the incidence of PEP among patients randomized to placebo or no-stent arms of RCTs has remained unchanged from 1977 to 2022 (P = .48).

CONCLUSIONS

The overall incidence of PEP is 10.2% but is 14.1% among high-risk patients based on this systematic review of placebo or no-stent arms of 145 RCTs; this rate has not changed between 1977 and 2022. Severe PEP and mortality from PEP are relatively uncommon.

Very Early Pouchitis Is Associated with an Increased Likelihood of Chronic Inflammatory Conditions of the Pouch

INTRODUCTION

Chronic inflammatory conditions of the pouch are common after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC).

AIMS

We aimed to investigate the relationship between acute pouchitis within 180 days of the final stage of IPAA surgery (very early pouchitis) and the future development of chronic antibiotic dependent pouchitis (CADP) and Crohn's-like disease of the pouch (CLDP).

METHODS

We performed a retrospective cohort study, evaluating patients who underwent proctocolectomy with IPAA between January 1, 2004 and December 31, 2016. Multivariable logistic regression was used to evaluate the relationship between very early pouchitis and the development of CADP and CLDP.

RESULTS

Among 626 patients undergoing IPAA for UC, 137 (22%) developed very early pouchitis, 75 (12%) developed CADP, and 59 (9%) developed CLDP in a median follow-up of 5.18 years (interquartile range 0.94-10.8 years). Very early pouchitis was associated with a significant increase in the odds of developing CADP (adjusted odds ratio [aOR3.65, 95% CI 2.19-6.10) as was primary sclerosing cholangitis (aOR 3.97, 95% CI 1.44-11.0). Very early pouchitis was associated with increased odds for developing CLDP (aOR 2.77, 95% CI 1.54-4.98) along with a family history of inflammatory bowel disease (aOR 2.10, 95% CI 1.11-3.96).

CONCLUSION

In this cohort, very early pouchitis was associated with an increased risk of developing CADP and CLDP. These findings highlight very early pouchitis as a unique risk factor for chronic inflammatory conditions of the pouch and the need for future studies evaluating potential strategies for secondary prophylaxis strategies in this population.

The landscape of immune dysregulation in Crohn's disease revealed through single-cell transcriptomic profiling in the ileum and colon

Crohn's disease (CD) is a chronic gastrointestinal disease that is increasing in prevalence worldwide. CD is multifactorial, involving the complex interplay of genetic, immune, and environmental factors, necessitating a system-level understanding of its etiology. To characterize cell-type-specific transcriptional heterogeneity in active CD, we profiled 720,633 cells from the terminal ileum and colon of 71 donors with varying inflammation status. Our integrated datasets revealed organ- and compartment-specific responses to acute and chronic inflammation; most immune changes were in cell composition, whereas transcriptional changes dominated among epithelial and stromal cells. These changes correlated with endoscopic inflammation, but small and large intestines exhibited distinct responses, which were particularly apparent when focusing on IBD risk genes. Finally, we mapped markers of disease-associated myofibroblast activation and identified CHMP1A, TBX3, and RNF168 as regulators of fibrotic complications. Altogether, our results provide a roadmap for understanding cell-type- and organ-specific differences in CD and potential directions for therapeutic development.

Comorbidity Influences the Comparative Safety of Biologic Therapy in Older Adults With Inflammatory Bowel Diseases

INTRODUCTION

There are limited data on comparative risk of infections with various biologic agents in older adults with inflammatory bowel diseases (IBDs). We aimed to assess the comparative safety of biologic agents in older IBD patients with varying comorbidity burden.

METHODS

We used data from a large, national commercial insurance plan in the United States to identify patients 60 years and older with IBD who newly initiated tumor necrosis factor-α antagonists (anti-TNF), vedolizumab, or ustekinumab. Comorbidity was defined using the Charlson Comorbidity Index (CCI). Our primary outcome was infection-related hospitalizations. Cox proportional hazards models were fitted in propensity score-weighted cohorts to compare the risk of infections between the different therapeutic classes.

RESULTS

The anti-TNF, vedolizumab, and ustekinumab cohorts included 2,369, 972, and 352 patients, respectively, with a mean age of 67 years. The overall rate of infection-related hospitalizations was similar to that of anti-TNF agents for patients initiating vedolizumab (hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.84-1.04) and ustekinumab (0.92, 95% CI 0.74-1.16). Among patients with a CCI of >1, both ustekinumab (HR: 0.66, 95% CI: 0.46-0.91, p-interaction <0.01) and vedolizumab (HR: 0.78, 95% CI: 0.65-0.94, p-interaction: 0.02) were associated with a significantly lower rate of infection-related hospitalizations compared with anti-TNFs. No difference was found among patients with a CCI of ≤1.

DISCUSSION

Among adults 60 years and older with IBD initiating biologic therapy, both vedolizumab and ustekinumab were associated with lower rates of infection-related hospitalizations than anti-TNF therapy for those with high comorbidity burden.

Relationship Between Stages of Ileal Pouch-Anal Anastomosis, Timing of Restoration of Fecal Continuity, and Pouchitis

BACKGROUND

The most common complication following ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC) is pouchitis.

AIMS

We aimed to investigate whether a shorter period between pouch creation and restoration of fecal flow through an IPAA was associated with an increased risk of development of pouchitis within the first 2 years after IPAA.

METHODS

We performed a retrospective cohort study evaluating patients undergoing colectomy with IPAA for UC between January 1, 2004 and December 31, 2016. We used Kaplan-Meier testing and Cox Proportional Hazards Modeling to evaluate the relationship between the time between restoration of fecal continuity and time to subsequent development of pouchitis, adjusting for other clinical and demographic factors.

RESULTS

We identified 624 patients who underwent proctocolectomy with IPAA for UC, of whom 246 (39%) developed pouchitis within the first 2 years after IPAA. There was no difference when comparing the median time to restoration of continuity among those patients who developed pouchitis and those who did not (49 days vs. 49 days, p = 0.85) or in multivariable analysis. Primary sclerosing cholangitis (Hazard Ratio [HR] 2.14, 95% CI 1.12-4.08), family history of inflammatory bowel disease (HR 1.49, 95% CI 1.08-2.06), and delayed pouch creation (HR 0.75, 95% CI 0.57-1.00) were significantly associated with time to development of pouchitis.

CONCLUSION

Although a staged approach to IPAA may have benefits in the surgical management of UC, the timing interval between pouch creation and restoration of continuity did not impact the subsequent development of early pouchitis in this cohort.

Current Perspectives on Indications for Ileal Pouch-Anal Anastomosis in Older Patients

The population of older patients with inflammatory bowel disease (IBD) is expected to continue to increase in the coming decades, which necessitates and improved understanding of the critical issues faced by patients in this population. Although restorative proctocolectomy with IPAA remains the surgical procedure of choice for the majority of patients with medically refractory ulcerative colitis (UC) and UC-related dysplasia, the evidence surrounding surgery for older patients UC remains sparse. In particular, comparisons of outcomes among older and younger patients undergoing IPAA and comparisons between older patients undergoing IPAA and those undergoing proctocolectomy with end ileostomy remain an understudied and important issue, as evidence in this area will be used to guide patient-centered surgical choices among older patients who require colectomy for UC. In this narrative review, we review the available literature regarding IPAA for older patients, as well as the pre-, peri-, and postoperative factors that may influence outcomes in this population.

Prevalence and Implications of Frailty in Older Adults With Incident Inflammatory Bowel Diseases: A Nationwide Cohort Study

BACKGROUND AND AIMS

We aimed to compare the risk of frailty in older adults with incident inflammatory bowel disease (IBD) and matched non-IBD comparators and assess the association between frailty and future hospitalizations and mortality.

METHODS

In a cohort of patients with incident IBD ≥60 years of age from 2007 to 2016 in Sweden identified using nationwide registers, we defined frailty using Hospital Frailty Risk Score. We compared prevalence of frailty in patients with IBD with age, sex, place of residency- and calendar year-matched population comparators. In the IBD cohort, we used Cox proportional hazards modeling to examine the associations between frailty risk and hospitalizations or mortality.

RESULTS

We identified 10,590 patients with IBD, 52% female with a mean age of 71 years of age, matched to 103,398 population-based comparators. Among patients with IBD, 39% had no risk for frailty, 49% had low risk for frailty, and 12% had higher risk for frailty. Mean Hospital Frailty Risk Score was 1.9 in IBD and 0.9 in matched comparators (P < .01). Older adults with IBD at higher risk for frailty had a 20% greater risk for mortality at 3 years compared with those who were not frail. Compared with nonfrail older patients with IBD, patients at higher risk for frailty had increased mortality (hazard ratio [HR], 3.22, 95% confidence interval [CI], 2.86-3.61), all-cause hospitalization (HR, 2.42; 95% CI, 2.24-2.61), and IBD-related hospitalization (HR, 1.50; 95% CI, 1.35-1.66). These associations were not attenuated after adjusting for comorbidities.

CONCLUSIONS

Frailty is more prevalent in older adults with IBD than in matched comparators. Among older patients with IBD, frailty is associated with increased risk for hospitalizations and mortality.

Sarcopenia in Inflammatory Bowel Diseases: Reviewing Past Work to Pave the Path for the Future

Purpose of the Review

Sarcopenia is the loss of muscle quantity and strength. It is highly prevalent in patients with inflammatory bowel disease (IBD) and is associated with periods of ongoing inflammation. This review will summarize the prior work in the field and highlight areas for future research.

Recent Findings

The presence of sarcopenia has been associated with adverse outcomes in different populations. Most recently, sarcopenia has been associated with adverse postoperative outcomes and an increased likelihood of surgery in IBD. Despite this, significant heterogeneity among these studies limits the ability to draw definitive conclusions.

Summary

The importance of sarcopenia in inflammatory bowel disease (IBD) is only beginning to be recognized. Future studies assessing it utility both as a risk stratification tool and a modifiable factor in IBD are needed.

The association between polypharmacy, frailty and disability-free survival in community-dwelling healthy older individuals

OBJECTIVES

Polypharmacy and frailty are two common geriatric conditions. In community-dwelling healthy older adults, we examined whether polypharmacy is associated with frailty and affects disability-free survival (DFS), assessed as a composite of death, dementia, or persistent physical disability.

METHODS

We included 19,114 participants (median age 74.0 years, IQR: 6.1 years) from ASPirin in Reducing Events in the Elderly (ASPREE) clinical trial. Frailty was assessed by a modified Fried phenotype and a deficit accumulation Frailty Index (FI). Polypharmacy was defined as concomitant use of five or more prescription medications. Multinomial logistic regression was used to examine the cross-sectional association between polypharmacy and frailty at base line, and Cox regression to determine the effect of polypharmacy and frailty on DFS over five years.

RESULTS

Individuals with polypharmacy (vs. <5 medications) were 55% more likely to be pre-frail (Relative Risk Ratio or RRR: 1.55; 95%Confidence Interval or CI:1.44, 1.68) and three times more likely to be frail (RRR: 3.34; 95%CI:2.64, 4.22) according to Fried phenotype. Frailty alone was associated with double risk of the composite outcome (Hazard ratio or HR: 2.16; 95%CI: 1.56, 2.99), but frail individuals using polypharmacy had a four-fold risk (HR: 4.24; 95%CI: 3.28, 5.47). Effect sizes were larger when frailty was assessed using the FI.

CONCLUSION

Polypharmacy was significantly associated with pre-frailty and frailty at baseline. Polypharmacy-exposed frailty increased the risk of reducing disability-free survival among older adults. Addressing polypharmacy in older people could ameliorate the impact of frailty on individuals' functional status, cognition and survival.

Association of midlife antibiotic use with subsequent cognitive function in women

The gut microbiome is increasingly recognized to play a role in cognition and dementia. Antibiotic use impacts the gut microbiome and has been linked with chronic disease. Despite these data, there is no evidence supporting an association between long-term antibiotic use in adults and cognitive function. We conducted a prospective population-based cohort study among 14,542 participants in the Nurses’ Health Study II who completed a self-administered computerized neuropsychological test battery between 2014–2018. Multivariate linear regression models were used to assess if chronic antibiotic use in midlife was associated with cognitive impairment assessed later in life. Women who reported at least 2 months of antibiotic exposure in midlife (mean age 54.7, SD 4.6) had lower mean cognitive scores seven years later, after adjustment for age and educational attainment of the spouse and parent, with a mean difference of -0.11 standard units for the global composite score (P_trend <0.0001), -0.13 for a composite score of psychomotor speed and attention (P_trend <0.0001), and -0.10 for a composite score of learning and working memory (P_trend <0.0001) compared with non-antibiotic users. These differences were not materially changed after multivariate adjustment for additional risk factors, including comorbid conditions. As a benchmark, the mean difference in score associated with each additional year of age was (-0.03) for global cognition, (-0.04) for psychomotor speed and attention, and (-0.03) for learning and working memory; thus the relation of antibiotic use to cognition was roughly equivalent to that found for three to four years of aging. Long-term antibiotic use in midlife is associated with small decreases in cognition assessed seven years later. These data underscore the importance of antibiotic stewardship, especially among aging populations.

Transmural Inflammation, Ileitis, and Granulomas at the Time of Proctocolectomy in Patients with Ulcerative Colitis Do Not Predict Future Development of Pouchitis

Background

The most common complication following ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC) is pouchitis. Our study aimed to investigate the relationship between histopathologic findings of ileitis, granuloma, or transmural inflammation on the colectomy specimen of patients with clinically and endoscopically diagnosed UC and the development of pouchitis within the first 2 years after IPAA.

Methods

We performed a retrospective cohort study evaluating patients undergoing colectomy with IPAA for UC between January 1, 2004 and December 31, 2016. Bivariate analyses were conducted to evaluate the relationship between clinical factors and the development of pouchitis. We performed multivariate logistic regression to evaluate the relationship between histologic, clinical, and demographic factors at the time of colectomy and subsequent development of pouchitis.

Results

Among 626 patients, pouchitis occurred in 246 (39%). Patients with primary sclerosing cholangitis were more likely to develop pouchitis (adjusted odds ratio [aOR] 2.81, 95% confidence interval [CI] 1.02-7.72), as were patients with a family history of inflammatory bowel disease (aOR 1.75, 95% CI 1.11-2.77). Histologic findings of ileitis, granuloma, or transmural inflammation were not associated with an increased odds of developing pouchitis (aOR 0.70, 95% CI 0.45-1.08).

Discussion/Conclusion

Patients with ileitis, granulomas, or transmural inflammation at the time of colectomy were not at greater risk for development of pouchitis in the 2 years after IPAA. These pathological findings should not preclude IPAA for UC.

The 5Ms of Geriatrics in Gastroenterology: The Path to Creating Age-Friendly Care for Older Adults With Inflammatory Bowel Diseases and Cirrhosis

The number of Americans 65 years or older in 2060 will be more than double what it was in 2014. Approximately 40% of patients seen in gastroenterology (GI) and hepatology practices in the United States are 60 years or older. Adapting care delivery models, curating data on shifting risk-benefit decisions with geriatric syndromes, understanding appropriate assessments, and focusing on tailored implementation strategies are challenges that are actively confronting us as we provide care for a burgeoning population of older adults. Limited availability of geriatric specialists results in an onus of specialists caring for older adults, such as gastroenterologists, to innovate and develop tailored, comprehensive, and evidence-based care for adults in later life stages. In this article, we present the 5M framework from geriatrics to achieve age-friendly healthcare. The 5Ms are medications, mind, mobility, multicomplexity, and what matters most. We apply the 5M framework to 2 chronic conditions commonly encountered in clinical GI practice: inflammatory bowel diseases and cirrhosis. We highlight knowledge gaps and outline future directions to expand evidence-based care and advance the creation of age-friendly GI care.

Frailty in inflammatory bowel diseases: an emerging concept

Inflammatory bowel diseases (IBD), consisting of Crohn's disease and ulcerative colitis, are chronic remitting, relapsing inflammatory conditions of the gastrointestinal tract. While traditionally a disease of younger ages, the number of older adults with IBD is rising rapidly. Patients with IBD often experience geriatric syndromes at earlier ages. Older adults with IBD have poorer disease and treatment-related outcomes compared with younger adults with IBD. Applying the principles of geriatrics to understanding a chronic disease in older adults may improve health span. Better tools are needed to stratify IBD patients who are at high risk for adverse events. Frailty is a geriatric construct that may approximate biologic age. Frailty is a complex, multi-dimensional syndrome that leads to increased vulnerability to stress and decline of reserve across multiple physiologic systems. In this review, we present the leading conceptual models of frailty and discuss the applications of frailty in immune-mediated diseases. We also review chronic conditions where frailty has been applied successfully as a tool for risk stratification. Finally, we discuss in the detail the growing body of literature highlighting the relationship between frailty and IBD, the epidemiology of frailty in IBD, and ramifications of frailty in IBD.

Home Infusions for Inflammatory Bowel Disease Are Safe: US Experience and Patient Perspectives

BACKGROUND

Home infusions (HIs) for biologic medications are an option for inflammatory bowel disease (IBD) patients in the United States. We aimed to describe the population receiving HIs and report patient experience with HIs.

METHODS

We conducted a retrospective cohort study in the Quintiles-IMSLegacy PharMetrics Adjudicated Claims Database from 2010 to 2016 to describe the population receiving infliximab (IFX) and vedolizumab (VDZ) HIs and determine predictors for an urgent/emergent visit post-HIs. We then administered a cross-sectional survey to IBD Partners Internet-based cohort participants to assess knowledge and experience with infusions.

RESULTS

We identified claims for 11 892 conventional IFX patients, 1573 home IFX patients, 438 conventional VDZ patients, and 138 home VDZ patients. There were no differences in demographics or median charges with IFX home and conventional infusions. Home VDZ infusions had a greater median charge than conventional VDZ infusion. Less than 4% of patients had an urgent/emergent visit post-HIs. Charlson comorbidity index > 0 (odds ratio [OR]: 1.95; 95% confidence interval [CI], 1.01-3.77) and Medicaid (OR: 3.01; 95% CI, 1.53-5.94) conferred significantly higher odds of urgent/emergent visit post-HIs. In IBD Partners, 644 IBD patients responded; 56 received HIs. The majority chose HIs to save time and preferred HIs to conventional infusions. Only 2 patients reported an urgent/emergent visit for HI-related problems.

CONCLUSIONS

HI appears to be safe in IBD patients receiving IFX and VDZ. However, patients with fewer resources and more comorbidities are at increased risk for an urgent/emergent visit post-HIs. The overall patient experience with HI is positive. Expansion of HIs may result in decreased therapy-related logistic burden for carefully selected patients.

Creation of a Case-Finding Definition for Identifying Patients With Acute Pouchitis in Administrative Claims Data

Acute pouchitis is the most common complication after a restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis, affecting 40% of patients within the first year after surgery.¹ Although up to 80% of patients can develop pouchitis symptoms,^2,3 substantial gaps remain in our understanding of the epidemiology and burden of pouchitis. Administrative claims have been used to advance the knowledge of other areas of inflammatory bowel disease^4-6; however, a prerequisite to conducting such studies in pouchitis is a valid, reliable case-finding algorithm. Given concerns that the International Classification of Diseases (ICD) code for pouchitis may not be reliably used by clinicians (resulting in a low sensitivity), the objectives of the study were to (1) develop a series of case-finding definitions for acute pouchitis and (2) compare the performance of these case-finding definitions to that of a single ICD code for pouchitis.

Patients With Inflammatory Bowel Diseases Are at Higher Risk for Meningitis

BACKGROUND

The epidemiology of meningitis is unknown in inflammatory bowel disease (IBD) patients.

GOALS

We aimed to determine the incidence of and risk factors for meningitis in IBD patients.

STUDY

We conducted a retrospective cohort and nested case-control study in the Quintiles IMS Legacy PharMetrics Adjudicated Claims Database from January 2001 to June 2016. We matched IBD patients to those without IBD on age, sex, enrollment, and region. Meningitis was defined as one code for meningitis associated with an emergency department visit or hospitalization. Meningitis risk was calculated with incidence rate ratios. In a nested case-control study of IBD patients, predictors for meningitis were determined with multivariable conditional logistic regression models.

RESULTS

We identified 50,029 patients with Crohn's disease (CD) and 59,830 patients with ulcerative colitis (UC) matched to 296,801 non-IBD comparators. There were 85 CD patients, 77 UC patients, and 235 comparators with meningitis. CD patients had 2.17 times the rate of meningitis and UC patients had 1.63 times the rate of meningitis as non-IBD comparators. After adjusting for relevant covariates among those with IBD, treatment with mesalamine was associated with a significantly lower odds of a meningitis claim (odds ratio: 0.40, 95% confidence interval: 0.26-0.62). Having at least one comorbidity was associated with a significantly higher odds of a meningitis claim (odds ratio: 2.21, 95% confidence interval: 1.76-2.77).

CONCLUSIONS

Although the overall rate of meningitis is low, IBD patients are at an increased risk compared with non-IBD comparators. Comorbidities are a risk factor for meningitis in IBD patients. Pneumococcal and meningococcal vaccinations should be discussed.

Vaping-associated esophagitis

BACKGROUND

Vaping, or e-cigarettes, heat nicotine and other chemicals to create a vapor that is inhaled. The practice has gained rapid popularity with 41 million people globally reporting regular or occasional use. Although tobacco smoking is well-known to increase esophageal acid exposure by augmenting the number of reflux events, the effects of vaping on the gastrointestinal tract have not yet been elucidated. Our objective is to report a case of severe esophagitis associated with vaping, which is the first in the literature to our knowledge.

CASE PRESENTATION

A 25-year-old male with a history of well-controlled gastro-esophageal reflux disease presented to the emergency room for evaluation of one week of severe odynophagia. He had been treated with a proton-pump inhibitor for several years with good effect. Approximately two months prior to presentation, he started vaping tetrahydrocannabinol and nicotine with recent heavy daily use. He denied any alcohol or non-steroidal anti-inflammatory drug use. We performed esophagogastroduodenoscopy that revealed Los Angeles Grade C esophagitis (involving ≥ 1 mucosal breaks continuous between tops of ≥ 2 mucosal folds, < 75% circumferential). Histopathological analysis of esophageal biopsies demonstrated granulation tissue with acute and chronic inflammation. Periodic acid-Schiff-diastase staining was negative and immunohistochemical stains for herpes simplex virus and cytomegalovirus were negative. There was no evidence of eosinophilic esophagitis. We treated him with intravenous PPI and analgesics until he was able to tolerate oral intake. He was counseled extensively on vaping cessation and reported complete resolution of symptoms after 2 months.

CONCLUSION

This patient's presentation illustrates a serious gastrointestinal consequence of vaping, the long-term consequences of which warrant additional studies. Like smoking, the mechanism of injury in vaping may be, at least in part, due to the effects of nicotine. As prevalence of vaping continues to rise, clinicians should be aware of this complication and carefully solicit a patient's vaping history as a simple denial of "smoking" can be misleading.

Utilization patterns and characteristics of users of biologic anti-inflammatory agents in a large, US commercially insured population

We report utilization patterns and characteristics of patients treated with biologic anti-inflammatory agents in a large commercially insured patient population in the United States. We identified adult (age ≥18 years) patients receiving biologic anti-inflammatory agents between 1 January 2012 and 31 March 2019 across the five Research Partners in the Biologic and Biosimilars Collective Intelligence Consortium's Distributed Research Network. We examined the number of incident use episodes for each biologic, as well as patient demographic and clinical characteristics. Curated data and analytic tools from the Food and Drug Administration's Sentinel System were used to perform the analyses. We identified 90,360 incident episodes of tumor necrosis factor-alpha inhibitors (TNFi) and 70,506 incident episodes of non-TNFi medications. Adalimumab was the most common TNFi drug (47% of all TNFi episodes) and showed a steady increase in utilization during the study period compared to other TNFi agents. Rituximab was the most commonly initiated non-TNFi medication (44% of non-TNFi episodes). Other non-TNFi agents, namely, ustekinumab, vedolizumab, and secukinumab, demonstrated notable increases in utilization over time. Biosimilar use was limited; we observed 653 incident episodes for infliximab-dyyb and 39 incident episodes for infliximab-abda. As more biologics enter the market, greater variation in the use of biologics with similar indications and between biologic originators and biosimilars is anticipated. Because information on efficacy and safety at the time of drug approval is limited, post-marketing surveillance and research is needed to monitor medication safety and evaluate effectiveness between biologic drugs using real-world data.

Immunosuppressive Therapy and Risk of COVID-19 Infection in Patients With Inflammatory Bowel Diseases

BACKGROUND

The effect of immunosuppressive treatment for immune-mediated diseases on risk of the novel coronavirus disease 2019 (COVID-19) has not been established. We aimed to define the effect of targeted biologic and immunomodulator therapy on risk of COVID-19 in a multi-institutional cohort of patients with inflammatory bowel disease (IBD).

METHODS

We identified patients 18 years and older who received care for IBD at Partners Healthcare between January 2019 and April 2020. The primary outcome was development of COVID-19 defined as a positive polymerase chain reaction test for severe acute respiratory syndrome coronavirus 2. Multivariable regression models were used to examine the effect of immunosuppression on risk of COVID-19 and its outcomes.

RESULTS

In a cohort of 5302 IBD patients, 39 (0.7%) developed COVID-19. There was no difference in age, sex, or race between IBD patients with and without COVID-19. The rate of COVID-19 was similar between patients treated with immunosuppression (0.8%) compared with those who were not (0.64%; P = 0.55). After adjusting for age, sex, race, and comorbidities, use of immunosuppressive therapy was not associated with an increased risk of COVID-19 (odds ratio, 1.73; 95% confidence interval, 0.82-3.63). The presence of obesity was associated with a higher risk of COVID-19 (odds ratio, 8.29; 95% confidence interval, 3.72-18.47). There were 7 hospitalizations, 3 intensive care unit stays, and 1 death. Older age and obesity but not immunosuppressive treatment were associated with severe COVID-19 infection.

CONCLUSIONS

The use of systemic immunosuppression was not associated with an increased risk of COVID-19 in a multi-institutional cohort of patients with IBD.

Yield of Random Biopsies During Colonoscopies in Inflammatory Bowel Disease Patients Undergoing Dysplasia Surveillance

BACKGROUND

The development of chromoendoscopy (CE) and high definition endoscopy (HDE) has improved detection of subtle colonic dysplasia in patients with inflammatory bowel diseases (IBDs). The role of random biopsies for dysplasia surveillance is unclear.

METHODS

We reviewed patients with IBD who underwent a CE or HDE colonoscopy and had colonic dysplasia detected. Detection of dysplasia was classified as either visible or random and graded as low grade dysplasia (LGD), high grade dysplasia (HGD), or indefinite for dysplasia. Multivariable regression adjusted for relevant confounders examined the predictors of dysplasia detectable on random biopsies alone.

RESULTS

The study included 300 patients (203 ulcerative colitis, 97 Crohn's disease with colonic involvement) contributing 442 colonoscopies; the mean disease duration was 24.5 years; 7.2% had primary sclerosing cholangitis (PSC). Three hundred sixty-two colonoscopies (82%) had only visible dysplasia, 52 (12%) had only random dysplasia, and 28 (6%) had both visible and random dysplasia. Longer disease duration (odds ratio, 1.04; 95% CI, 1.01-1.07), active inflammation (odds ratio, 2.89; 95% CI, 1.26-6.67), and concomitant PSC (odds ratio, 3.66; 95% CI, 1.21-11.08) were associated with detecting dysplasia on random biopsies compared with visible lesions. Patients with random dysplasia (21%) or both random and visible dysplasia (21%) were more likely to undergo surgical resection compared with those with only visible dysplasia (5%; P < 0.001) and have subsequent development of colorectal cancer (15%, 7%, 1%, respectively; P < 0.0001).

CONCLUSION

Nearly one fifth of dysplasia detected in patients with IBD was found on random biopsies. Patients with high risk characteristics may benefit from continuing the practice of random biopsies during surveillance examinations.

Body Image Dissatisfaction among Pediatric Patients with Inflammatory Bowel Disease

OBJECTIVES

To determine risk factors for body image dissatisfaction among pediatric patients with inflammatory bowel disease (IBD).

STUDY DESIGN

We performed a cross-sectional study of children aged 9-18 years in the IBD Partners Kids & Teens cohort. Participants completed surveys including demographics, disease characteristics and activity indices, and psychosocial outcomes measured by IMPACT-III questionnaires. We defined body image dissatisfaction if participants answered "I look awful" or "I look bad." Bivariate analyses assessed associations between body image dissatisfaction and demographic, disease-related and psychosocial factors; logistic regression models evaluated associations between risk factors and body image dissatisfaction.

RESULTS

IMPACT-III was completed by 664 patients, with 74 (11.1%) reporting body image dissatisfaction. Patients with body image dissatisfaction were more likely to be female (P < .01), older (median age 15 vs 13 years, P < .01), and diagnosed with IBD at an older age (12 vs 10 years, P < .01). Those with body image dissatisfaction had greater body mass index percentile (P = .02), more active disease (P < .01), more current steroid use (P < .01), and more depression and anxiety (P < .01). Female sex (OR 2.31; 95% CI 1.22-4.39), depression (OR 4.73; 95% CI 2.41-9.26), and anxiety (OR 5.42; 95% CI 2.48-11.80) were independently associated with body image dissatisfaction.

CONCLUSIONS

In this cohort, risk factors for body image dissatisfaction include female sex, older age at diagnosis, active disease, current steroid use, greater body mass index, and comorbid mood disorder. Interventions targeting modifiable risk factors for body image dissatisfaction may improve quality of life in pediatric patients with body image dissatisfaction.

Frailty is independently associated with mortality in 11 001 patients with inflammatory bowel diseases

BACKGROUND

The prevalence of older adults with inflammatory bowel diseases (IBD) is increasing. Frailty is an important predictor of outcomes in many chronic disease states. The implications of frailty have not been well-delineated in IBD.

AIMS

To report the prevalence of a frailty-associated diagnosis and determine the association between frailty and mortality in a cohort of IBD patients.

METHODS

In a cohort of 11 001 IBD patients, we applied a validated definition of frailty using International Classification of Disease codes. We compared frail IBD patients to those without a frailty-related code ("fit"). We constructed multivariable logistic regression models adjusting for clinically pertinent confounders (age, gender, race, IBD type, follow-up, IBD-related surgery, ≥1 comorbidity in the Charlson comorbidity index [CCI], and immunosuppression use) to determine whether frailty predicts mortality.

RESULTS

A total of 675 (6%) IBD patients had a frailty-related diagnosis. The prevalence of frailty increased with age, rising from 4% in 20-29 year olds to 25% in patients 90 years or older. The most prevalent frailty diagnosis was protein-energy malnutrition. The strongest predictors of frailty were non-IBD comorbidity, all-cause and IBD-related, hospitalisations. Frailty remained independently associated with mortality after adjusting for age, sex, duration of follow-up, comorbidity, need for IBD-related surgery and immunosuppression (OR: 2.90, 95% CI: 2.29-3.68).

CONCLUSIONS

Frailty is prevalent in IBD patients and increases with age. Frailty nearly triples the odds of mortality for IBD patients. Risk stratifying patients by frailty may improve outcomes.

Pretreatment Frailty Is Independently Associated With Increased Risk of Infections After Immunosuppression in Patients With Inflammatory Bowel Diseases

BACKGROUND & AIMS

Infections are an important adverse effect of immunosuppression for treatment of inflammatory bowel diseases (IBDs). However, risk of infection cannot be sufficiently determined based on patients' ages or comorbidities. Frailty has been associated with outcomes of patients with other inflammatory diseases. We aimed to determine the association between frailty and risk of infections after immunosuppression for IBD.

METHODS

We performed a cohort study of 11,001 patients with IBD, using a validated frailty definition based on International Classification of Disease codes to identify patients who were frail vs fit in the 2 years before initiation of an anti-tumor necrosis factor (TNF) or immunomodulator therapy, from 1996 through 2010. Our primary outcome was an infection in the first year after treatment. We constructed multivariable logistic regression models, adjusting for clinically pertinent confounders (age, comorbidities, steroid use, and combination therapy) to determine the association between frailty and posttreatment infections.

RESULTS

There were 1299 patients treated with an anti-TNF agent and 2676 patients treated with an immunomodulator. In this cohort, 5% of patients who received anti-TNF therapy and 7% of patients who received an immunomodulator were frail in the 2 years before immunosuppression. Frail patients were older and had more comorbidities. Higher proportions of frail patients developed infections after treatment (19% after TNF and 17% after immunomodulators) compared with fit patients (9% after TNF and 7% after immunomodulators; P < .01 for frail vs fit in both groups). Frail patients had an increased risk of infection after we adjusted for age, comorbidities, and concomitant medications (anti-TNF adjusted odds ratio, 2.05 [95% confidence interval, 1.07-3.93] and immunomodulator adjusted odds ratio, 1.81 [95% confidence interval, 1.22-2.70]).

CONCLUSIONS

Frailty was associated with infections after immunosuppression in patients with IBD after we adjust for age and comorbidities. Systematic assessment and strategies to improve frailty might reduce infection risk in patients with IBD.

The Early Experience With Vedolizumab in the United States

BACKGROUND

Post-marketing studies of new inflammatory bowel disease (IBD) therapies are needed to establish clinical effectiveness and safety in clinical practice. We aimed to describe the U.S. experience with vedolizumab in a commercially insured population.

METHODS

We conducted a retrospective cohort study in Quintiles-IMS Legacy PharMetrics Adjudicated Claims Database from May 2014 to June 2016. We included new vedolizumab users with Crohn disease (CD) and ulcerative colitis (UC) between 18 and 64 years with ≥12 months of continuous enrollment prior to initiating vedolizumab. Outcomes included treatment persistence >14 weeks, late steroid use, IBD-related surgery and infections associated with hospitalization. We built multivariable regression models to identify predictors of treatment persistence and late steroid use.

RESULTS

We identified 269 CD and 187 UC vedolizumab initiators. Only 60% of CD patients and 56% of UC patients remained on vedolizumab after 14 weeks without IBD-related hospitalization, surgery, and corticosteroid use. There were no significant predictors of treatment persistence. Steroid use in the first 2 months of vedolizumab initiation was a significant predictor of late steroid use in CD (odds ratio: 23.34; 95% confidence interval: 5.10-153.89). In the 6 months after vedolizumab initiation, 1.9% of CD and 5.9% of UC patients had an IBD-related surgery. Serious infections were <4%.

CONCLUSIONS

These data reflect the early U.S. experience with vedolizumab. The population-level response to vedolizumab therapy is just >50%. Steroids at the time of vedolizumab initiation is the strongest predictor of late steroid use in CD. Rates of surgery and serious infections are low.

Chronic Antibiotic Dependent Pouchitis Is Associated With Older Age at the Time of Ileal Pouch Anal Anastomosis (J-pouch) Surgery

BACKGROUND

Risk factors for the development of chronic antibiotic dependent pouchitis (CADP) are not well understood.

METHODS

Using multivariable logistic regression, we compared clinical factors between 194 patients with acute antibiotic responsive pouchitis or CADP.

RESULTS

Individuals with CADP were significantly older (40.9 vs 30.8 years, P < 0.001) and demonstrated a longer disease duration before IPAA (10.3 vs 7.0 years, P = 0.004). Age ≥55 years at the time of IPAA was significantly associated with CADP (adjusted odds ratio = 4.35, 95% confidence interval = 1.01-18.7).

CONCLUSIONS

Although older age should not represent a barrier to IPAA, further studies evaluating etiologies of this association are warranted.

The Incidence and Definition of Crohn's Disease of the Pouch: A Systematic Review and Meta-analysis

BACKGROUND

A subset of patients who undergo total proctocolectomy with ileal pouch-anal anastomosis (IPAA) creation for ulcerative colitis (UC) will later develop Crohn's disease (CD) of the pouch, which has been associated with significant morbidity. We aimed to analyze the incidence of CD of the pouch and to review the existing diagnostic criteria utilized.

METHODS

A systematic search performed through March 1, 2018, identified 12 studies that reported the incidence of CD of the pouch after IPAA for UC or indeterminate colitis (IC). We compiled all diagnostic criteria utilized in these studies and then performed a meta-analysis using random effects modeling to estimate the overall incidence of CD of the pouch in this population.

RESULTS

Among 4843 patients with an IPAA for UC or IC, 10.3% of patients were ultimately diagnosed with CD of the pouch (95% confidence interval [CI], 6.1%-15.4%). The most commonly reported diagnostic criteria were (1) presence of fistula/fistulae, (2) stricture involving the pouch or prepouch ileum, and (3) presence of prepouch ileitis. In a secondary analysis, excluding those studies that included patients with a preoperative diagnosis of IC, the incidence of CD of the pouch was 12.4% (95% CI, 9.0%-16.1%).

CONCLUSIONS

The estimated incidence of 10.3% will assist gastroenterologists and surgeons in preoperative counseling regarding the potential to develop CD of the pouch. There is an unmet need for common diagnostic criteria for a more standardized approach to the diagnosis of CD of the pouch.

Tofacitinib for the Treatment of Pyoderma Gangrenosum

Pyoderma gangrenosum (PG) is a difficult-to-treat inflammatory skin condition that affects inflammatory bowel disease (IBD) patients. There is no standardized approach for PG treatment.¹ We report the results of 3 patients with Crohn's disease (CD) and refractory PG who had failed several therapies with biologics and were started on tofacitinib for severe inflammatory arthritis with resolution of their PG.

Increased Prevalence of Esophageal Eosinophilia in Patients with Inflammatory Bowel Disease

Background

The overlap between eosinophilic esophagitis (EoE) and inflammatory bowel disease (IBD) has not been extensively examined. We aimed to assess the prevalence of esophageal eosinophilia in patients with IBD.

Methods

We conducted a retrospective cohort study using diagnostic codes to identify adults with EoE and IBD between 2008 and 2016 at a tertiary care center. Electronic medical records were reviewed to extract clinical, endoscopic, and treatment data. Patients with esophageal eosinophilia and IBD were compared to EoE cases without IBD.

Results

Of 621 EoE patients and 4,814 IBD patients identified, 35 had a code for both diseases and 12 were confirmed to have overlapping IBD and esophageal eosinophilia. The prevalence of esophageal eosinophilia in IBD was 12/4814 (0.25%), and the prevalence of confirmed EoE in IBD was 5/4,814 (0.10%). There were no substantial clinical, endoscopic, or histologic differences between EoE patients with and without IBD. IBD was diagnosed before esophageal eosinophilia 92% of the time, with an average time between diagnoses of 9.6 years. Of the IBD patients, 71% were started on biologic anti-tumor necrosis factor-α therapy an average of 7.6 years prior to developing esophageal eosinophilia.

Conclusions

The prevalence of esophageal eosinophilia in IBD is 5 times higher than expected in the general population (0.25 vs. 0.05%) and EoE in IBD is 2 times higher than expected (0.10 vs. 0.05%). Upper gastrointestinal (GI) symptoms in patients with IBD should merit evaluation not only for upper GI Crohn's disease, but also for esophageal eosinophilia.

Burden and Cost of Gastrointestinal, Liver, and Pancreatic Diseases in the United States: Update 2018

BACKGROUND & AIMS

Estimates of disease burden can inform national health priorities for research, clinical care, and policy. We aimed to estimate health care use and spending among gastrointestinal (GI) (including luminal, liver, and pancreatic) diseases in the United States.

METHODS

We estimated health care use and spending based on the most currently available administrative claims from commercial and Medicare Supplemental plans, data from the GI Quality Improvement Consortium Registry, and national databases.

RESULTS

In 2015, annual health care expenditures for gastrointestinal diseases totaled $135.9 billion. Hepatitis ($23.3 billion), esophageal disorders ($18.1 billion), biliary tract disease ($10.3 billion), abdominal pain ($10.2 billion), and inflammatory bowel disease ($7.2 billion) were the most expensive. Yearly, there were more than 54.4 million ambulatory visits with a primary diagnosis for a GI disease, 3.0 million hospital admissions, and 540,500 all-cause 30-day readmissions. There were 266,600 new cases of GI cancers diagnosed and 144,300 cancer deaths. Each year, there were 97,700 deaths from non-malignant GI diseases. An estimated 11.0 million colonoscopies, 6.1 million upper endoscopies, 313,000 flexible sigmoidoscopies, 178,400 upper endoscopic ultrasound examinations, and 169,500 endoscopic retrograde cholangiopancreatography procedures were performed annually. Among average-risk persons aged 50-75 years who underwent colonoscopy, 34.6% had 1 or more adenomatous polyps, 4.7% had 1 or more advanced adenomatous polyps, and 5.7% had 1 or more serrated polyps removed.

CONCLUSIONS

GI diseases contribute substantially to health care use in the United States. Total expenditures for GI diseases are $135.9 billion annually-greater than for other common diseases. Expenditures are likely to continue increasing.

Lack of Difference in Treatment Patterns and Clinical Outcomes Between Black and White Patients With Inflammatory Bowel Disease

BACKGROUND

Previous reports have shown differences in phenotypes among black patients with inflammatory bowel disease (IBD) compared with other racial groups, but prior studies were limited by small numbers of black patients and cross-sectional analyses. We used data from the Sinai-Helmsley Alliance for Research Excellence cohort to compare phenotypes and treatment patterns of black and white patients with IBD in a prospective study.

METHODS

We compared phenotypes, IBD-specific therapies, and health care utilization among black and white patients with IBD. For all analyses, we performed bivariate analyses and multivariable logistic regression to adjust for potential confounders.

RESULTS

Among 5537 patients with IBD, 314 (6%) reported black race. Black patients were more likely to report a Crohn's disease (CD)-related complication at baseline (adjusted odds ratio [aOR], 1.44; 95% confidence interval [CI], 1.06-1.95). Black patients with CD were more likely to develop a new abscess (aOR, 2.27; 95% CI, 1.31-3.93) and initiate an anti-tumor necrosis factor therapy during follow-up (aOR, 1.85; 95% CI, 1.09-3.14). Black patients with ulcerative colitis were more likely to have proctitis (24% vs 13%, P = 0.033) at baseline. There were no differences in surgery or hospitalization rates during the follow-up period.

CONCLUSIONS

Black patients with CD demonstrated increased complications at baseline and during follow-up in this cohort. Despite more complicated disease, black and white patients with IBD were generally given the same medications and experienced similar rates of hospitalization and surgery during the study period. In our multicenter cohort, clinical outcomes among black and white patients with IBD were similar.

Vaccinations in Adult Patients with Inflammatory Bowel Diseases in the West

BACKGROUND

Patients with moderate-severe inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis are commonly treated with long-term immunosuppressive therapies involving immunomodulators such as thiopurines, biologics (anti-TNF and anti-adhesion molecules), or novel small molecules such as Janus kinase inhibitors.

SUMMARY

Some infections seen with immunosuppressive therapy in IBD are preventable with vaccines. IBD-specific immunosuppressive therapy is generally initiated by gastroenterologists. Therefore, gastroenterologists should comprehend the appropriate application of vaccines such as hepatitis B, pneumonia, and herpes zoster vaccinations. This review summarizes the current guidance for vaccinations of IBD patients in the United States.

KEY MESSAGE

Gastroenterologists treating IBD patients must be aware of necessary vaccination schedules in the setting of immunosuppressive therapies.

Delayed Ileal Pouch Anal Anastomosis Has a Lower 30-Day Adverse Event Rate: Analysis From the National Surgical Quality Improvement Program

BACKGROUND

Ulcerative colitis (UC) patients requiring colectomy often have a staged ileal pouch anal anastomosis (IPAA). There are no prospective data comparing timing of pouch creation. We aimed to compare 30-day adverse event rates for pouch creation at the time of colectomy (PTC) with delayed pouch creation (DPC).

METHODS

Using prospectively collected data from 2011-2015 through the National Surgical Quality Improvement Program, we conducted a cohort study including subjects aged ≥18 years with a postoperative diagnosis of UC. We assessed 30-day postoperative rates of unplanned readmissions, reoperations, and major and minor adverse events (AEs), comparing the stage of the surgery where the pouch creation took place. Using a modified Poisson regression model, we estimated risk ratios (RRs) with 95% confidence intervals (CIs) adjusting for age, sex, race, body mass index, smoking status, diabetes, albumin, and comorbidities.

RESULTS

Of 2390 IPAA procedures, 1571 were PTC and 819 were DPC. In the PTC group, 51% were on chronic immunosuppression preoperatively, compared with 15% in the DPC group (P < 0.01). After controlling for confounders, patients who had DPC were significantly less likely to have unplanned reoperations (RR, 0.42; 95% CI, 0.24-0.75), major AEs (RR, 0.72; 95% CI, 0.52-0.99), and minor AEs (RR, 0.48; 95% CI, 0.32-0.73) than PTC.

CONCLUSIONS

Patients undergoing delayed pouch creation were at lower risk for unplanned reoperations and major and minor adverse events compared with patients undergoing pouch creation at the time of colectomy. 10.1093/ibd/izy082_video1izy082.video15776112442001.

A diagnosis of eosinophilic esophagitis is associated with increased life insurance premiums

Eosinophilic esophagitis (EoE) is a chronic disease that can be diagnosed at any age, but is not associated with malignancy and does not shorten lifespan. It remains unknown whether an EoE diagnosis affects insurability or insurance premium costs. We therefore aimed to determine whether a diagnosis of EoE affects the costs of life insurance. Our investigation was a secret shopper audit study whereby we contacted national insurance companies in the United States to evaluate the effect of a diagnosis of EoE on life insurance premiums. We constructed standardized case scenarios for males and females, including a 25-year-old and a 48-year-old without other comorbid conditions, who either had or did not have a diagnosis of EoE. Companies were asked for their best estimate for a $100,000 whole life insurance policy. Comparisons between median premiums were made using the Mann-Whitney U test. There were 20 national life insurance companies contacted and a total of 73 quotes were obtained. The median premium rate was similar for EoE and non-EoE cases at the younger age ($828 [IQR $576-1,020] vs. $756 [IQR $504-$804]; P = 0.10). However, the premium for the older case without EoE was 19% less expensive compared to a case with EoE ($1990 [IQR $1,248-2,350] vs. $2,375 [IQR $2,100-2568; P = 0.02]. This finding was not explained by sex or state of residence. Based on these findings, we conclude that life insurance premiums are significantly more expensive in the older patient case with EoE when compared to the same case without EoE. Patients with EoE and their providers should be aware of the additional cost associated with this diagnosis.
