Incidence and Treatment of Patients Diagnosed With Inflammatory Bowel Diseases at 60 Years or Older in Sweden

Inflammatory bowel disease, age of its onset and incident psychiatric disorders: The role of post-IBD lifestyle and medications

BACKGROUND

Individuals with inflammatory bowel disease (IBD) are at an increased risk to developing psychiatric disorders (PDs). However, the age of onset patterns for IBD-related PDs and the role of post-IBD lifestyle on the risk of subsequent PDs remain unclear.

METHODS

394,851 PD-free participants at baseline from the UK Biobank were included, of which 4408 individuals had a history of IBD (2851 ulcerative colitis [UC] and 1200 Crohn's disease [CD]). A combined lifestyle score was constructed and classified into three categories. Cox regression models were applied to evaluate the associations of age of IBD onset and lifestyle categories with PDs risk.

RESULTS

Over a median follow-up of 13.6 years, 56,392 participants were diagnosed with PDs. Participants with IBD had a higher risk of psychiatric morbidity [IBD: hazard ratio (HR):1.20, 95 % confidence interval (CI): 1.11-1.29; UC: HR: 1.21, 95 % CI: 1.11-1.33; CD: HR: 1.15, 95 % CI: 1.01-1.31] compared to non-IBD participants. The risk of PDs increased with advancing age of IBD onset [≤40 years, HR: 1.16, 95 % CI: 1.05-1.29; 40-50 years, HR: 1.19, 95 % CI: 1.02-1.39; >50 years, HR: 1.26, 95 % CI: 1.11-1.42]. Subgroup analysis showed that IBD patients receiving medications did not exhibit an elevated risk of PDs, irrespective of age of onset. Additionally, adherence to a favorable lifestyle significantly reduced the risk of PDs among IBD patients (HR: 0.53, 95 % CI: 0.42-0.67).

CONCLUSION

Individuals with later-onset IBD are more vulnerable to develop any PDs than younger, but adherence to a favorable post-IBD lifestyle and medications may protect against PDs.

Age-related impairment of intestinal inflammation resolution through an eicosanoid-immune-microbiota axis

Aging manifests a decline of immune function, induces microbiome dysbiosis, drives organ inflammation, and impedes the resolution of inflammation. However, the mechanisms underlying age-related intestinal inflammation remain poorly described. Here, we find that the resolution of T cell-initiated intestinal inflammation is impaired with aging. This impairment is mediated by disrupting the immune-microbiota interplay, controlled by intestinal eicosanoid metabolism. Pharmacologically inhibiting eicosanoid biosynthesis, blocking the prostaglandin E receptor subtype 4 (EP4), or genetically ablating EP4 diminishes age-related impairment of intestinal inflammation resolution. Mechanistically, mononuclear phagocyte-intrinsic eicosanoid-EP4 signaling impedes the resolution of intestinal inflammation through fostering gut microbial dysbiosis and, more importantly, interrupting segmented filamentous bacterial adhesion to the intestinal epithelium. Colonization with EP4-ablated mouse microbiota or segmented filamentous bacteria improves the resolution of intestinal inflammation. These findings reveal that eicosanoid-dependent immune-microbiota interactions impair inflammation resolution in the aged intestine, highlighting potential intervention strategies for improving age-related gut health.

Comparative Safety and Effectiveness of Ustekinumab and Anti-TNF in Elderly Crohn's Disease Patients

BACKGROUND

Biologic therapies are associated with increased infection risk among elderly patients with inflammatory bowel disease (IBD). However, there are few data on the safety and effectiveness of ustekinumab compared with anti-tumor necrosis factor (anti-TNF) agents in the elderly.

METHODS

The study sought to compare the safety and effectiveness of ustekinumab and anti-TNF agents in elderly Crohn's disease (CD) patients. Patients ≥60 years of age who commenced ustekinumab or an anti-TNF agent for CD were included in this retrospective multicenter cohort. The primary outcome was incidence of serious infections requiring hospitalization. Effectiveness was assessed by clinical remission, clinical response, and treatment persistence rates at 6 months. We adjusted for confounders using inverse probability of treatment weighting (IPTW) and performed a logistic regression analysis to assess factors associated with serious infections, clinical remission, and treatment persistence.

RESULTS

Eighty-three patients commencing ustekinumab and 124 commencing anti-TNF therapy were included. There was no difference in serious infection rates between anti-TNF agents (2.8%) and ustekinumab (3.1%) (P = .924) after propensity adjustment. Clinical remission rates were comparable at 6 months for ustekinumab (55.9%) and anti-TNF agents (52.4%) (P = .762). There was a significant reduction in HBI at 6 months in both groups. Treatment persistence was comparable between ustekinumab (90.6%) and anti-TNF agents (90.0%) at 6 months. Cox regression analysis did not show differences in treatment persistence (hazard ratio, 1.23; 95% confidence interval, 0.57-2.61; P = .594) and serious infection incidence (hazard ratio, 1.38; 95% confidence interval, 0.25-7.57; P = .709) by 6 months.

CONCLUSIONS

We observed comparable safety and effectiveness for ustekinumab and anti-TNF agents in treating elderly CD patients.

Cohort profile: the Swedish Inception Cohort in inflammatory bowel disease (SIC-IBD)

PURPOSE

There is a need for diagnostic and prognostic biosignatures to improve long-term outcomes in inflammatory bowel disease (IBD). Here, we describe the establishment of the Swedish Inception Cohort in IBD (SIC-IBD) and demonstrate its potential for the identification of such signatures.

PARTICIPANTS

Patients aged ≥18 years with gastrointestinal symptoms who were referred to the gastroenterology unit due to suspected IBD at eight Swedish hospitals between November 2011 and March 2021 were eligible for inclusion.

FINDINGS TO DATE

In total, 367 patients with IBD (Crohn's disease, n=142; ulcerative colitis, n=201; IBD-unclassified, n=24) and 168 symptomatic controls were included. In addition, 59 healthy controls without gastrointestinal symptoms were recruited as a second control group. Biospecimens and clinical data were collected at inclusion and in patients with IBD also during follow-up to 10 years. Levels of faecal calprotectin and high-sensitivity C-reactive protein were higher in patients with IBD compared with symptomatic controls and healthy controls. Preliminary results highlight the potential of serum protein signatures and autoantibodies, as well as results from faecal markers, to differentiate between IBD and symptomatic controls in the cohort. During the first year of follow-up, 37% (53/142) of the patients with Crohn's disease, 24% (48/201) with ulcerative colitis and 4% (1/24) with IBD-U experienced an aggressive disease course.

FUTURE PLANS

We have established an inception cohort enabling ongoing initiatives to collect and generate clinical data and multi-omics datasets. The cohort will allow analyses for translation into candidate biosignatures to support clinical decision-making in IBD. Additionally, the data will provide insights into mechanisms of disease pathogenesis.

Spanish Working Group in Crohn's Disease and Ulcerative Colitis (GETECCU) position paper on cardiovascular disease in patients with inflammatory bowel disease

Cardiovascular diseases (CVD) are the leading cause of death worldwide. Therefore, it is essential to understand their relationship and prevalence in different diseases that may present specific risk factors for them. The objective of this document is to analyze the specific prevalence of CVD in patients with inflammatory bowel disease (IBD), describing the presence of classical and non-classical cardiovascular risk factors in these patients. Additionally, we will detail the pathophysiology of atherosclerosis in this patient group and the different methods used to assess cardiovascular risk, including the use of risk calculators in clinical practice and different ways to assess subclinical atherosclerosis and endothelial dysfunction. Furthermore, we will describe the potential influence of medication used for managing patients with IBD on cardiovascular risk, as well as the potential influence of commonly used drugs for managing CVD on the course of IBD. The document provides comments and evidence-based recommendations based on available evidence and expert opinion. An interdisciplinary group of gastroenterologists specialized in IBD management, along with a consulting cardiologist for this type of patients, participated in the development of these recommendations by the Spanish Group of Work on Crohn's Disease and Ulcerative Colitis (GETECCU).

Substantial Reduction of Systemic Corticosteroid Use After Primary Ileocaecal Resection in Swedish Patients With Crohn's Disease: A Population-Based Cohort Study

BACKGROUND

The corticosteroid-sparing effects of ileocaecal resection have not been thoroughly investigated in a population-based cohort.

AIM

To investigate systemic corticosteroid use before and after primary ileocaecal resection in patients with Crohn's disease.

METHODS

Through nationwide registries, we identified 1565 patients with Crohn's disease undergoing primary ileocaecal resection in Sweden 2006-2019. We stratified patients according to mean annual systemic corticosteroid (prednisolone equivalents) use in the last 5 years before surgery and compared Crohn's disease treatment after surgery.

RESULTS

Some 19% (290/1565) of the patients had a mean annual corticosteroid use of ≥ 1000 mg up to 5 years pre-operatively, of whom 33% (97/290) had ≥ 2000 mg. Mean annual pre-operative CS use did not decrease during the study period (p = 0.35). Compared with patients with < 1000 mg/year pre-operative steroid use, patients with ≥ 1000 mg/year had more frequent previous bowel surgery (10% vs. 16%), exposure to biologics (29% vs. 38%), and immunomodulators (56% vs. 83%). Patients with a pre-operative mean annual corticosteroid use of ≥ 1000 mg had a mean annual reduction in corticosteroid use of 1354 mg after ileocaecal resection (1847 mg pre-operative versus 493 mg post-operative). During follow-up (median 6.8 years), exposure to biologics was similar among patients with different levels of pre-operative corticosteroid use.

CONCLUSION

Our results suggest a significant corticosteroid-sparing effect of ileocaecal resection in Crohn's disease patients with high pre-operative use, indicating a beneficial outcome of earlier surgical intervention. Despite increasing use of biologics, pre-operative corticosteroid use was consistent over the study period.

Older Adults with Inflammatory Bowel Disease Epidemiology in the United States: 2000-2021

BACKGROUND

As the United States population ages, the incidence and prevalence of inflammatory bowel disease (IBD) among older adults are on the rise.

AIMS

This study provides updated estimates of the IBD burden in older adults and examines changes from 2000 to 2021.

METHODS

We analyzed data on IBD incidence, prevalence, and disability-adjusted life years (DALYs) in older adults (> 70 years) in the United States from the Global Burden of Disease Study 2021, stratified by sex and state. Using the Joinpoint regression model, we evaluated age-standardized rate changes from 2000 to 2021.

RESULTS

The study estimated 11,250 new cases, 180,880 prevalent cases, and 80,410 DALYs from IBD in older adults in the United States in 2021. In 2021, older adults-onset represented 15% of the total IBD population in the United States, a 3% increase since 2000. Between 2000 and 2021, the incidence (Annual percent change [APC]: 0.58%, 95%CI 0.50 to 0.66%) and DALYs rates (APC: 0.34%, 95%CI 0.07 to 0.62%) increased, while the prevalence rates remained stable. Incidence rate increased at a higher extent in older adults-onset IBD in females compared to that of males. Forty-seven states experienced increased older adults-onset IBD incidence rates during this period.

CONCLUSION

From 2000 to 2021, the incidence and disability rates of older adults-onset IBD increased in the United States. Although older males initially had higher incidence rates, the rates have disproportionately increased among older females. The proportion of older adults-onset IBD cases and related disability has also grown, highlighting the urgent need for strategies to address the rising IBD burden in older adults.

Risk of Age-related and Disease-related Complications and Mortality in Elderly-onset Inflammatory Bowel Disease - A Population-based Study

BACKGROUND & AIMS

In this nationwide cohort from Israel (Epi-IIRN), we aimed to characterize risks for age-related complications, mortality, and inflammatory bowel disease (IBD)-related surgeries in patients with elderly-onset IBD (EO-IBD).

METHODS

Data of patients with EO-IBD (≥65 years) diagnosed during 2005 to 2020 were retrieved from the epi-IIRN database. Patients with EO-IBD were compared with 3 age-, sex-, and district-matched non-IBD individuals, for age-related outcomes. Patients with incident EO-IBD were matched to 4 adult-onset (AO) IBD (≥18-65 years) by IBD subtype, sex, and district. Cumulative incidence functions were calculated to estimate event probabilities over time, accounting for death as a competing risk. Proportional subdistribution hazards models were used to assess predictors of medication use, surgery, and complications.

RESULTS

Of 2826 EO-IBD cases, 2162 had 3 matched non-IBD controls. Mortality rates per 1000 person-years (PY) were similar in EO-IBD and non-IBD controls (292.32; 95% confidence interval [CI], 273.53-311.85 vs 291.24; 95% CI, 280.31-302.42, respectively) as were mortality causes and risk for pneumonia (adjusted hazard rate [aHR], 1.04; 95% CI, 0.84-1.29), fractures (aHR, 1.03; 95% CI, 0.82-1.29), bacteremia (aHR, 2.16; 95% CI, 0.87-5.40), and thromboembolism (aHR, 0.58; 95% CI, 0.27-1.23). When matching 2826 patients with EO-IBD to 11,304 patients with AO-IBD, the EO-IBD group had lower exposure to thiopurines (aHR, 0.44; 95% CI, 0.39-0.49) and anti-tumor necrosis factor (TNF) (aHR, 0.37; 95% CI, 0.32-0.42) and higher risk for abdominal surgery (aHR, 1.23; 95% CI, 1.04-1.46) in Crohn's disease [CD]; aHR, 1.51; 95% CI, 2.04-3.08 in ulcerative colitis [UC], respectively) but lower perianal surgery risk (hazard ratio [HR], 0.27; 95% CI, 0.16-0.47) in CD. The calculated frequencies of repeat perianal and abdominal surgery in the EO-CD and AO-CD groups at 3 years were 7.1% and 36%, respectively, and 29% and 21%, respectively.

CONCLUSIONS

Compared with non-IBD elderly, patients with EO-IBD have similar risks for death and complications. Compared with AO-IBD, patients with EO-IBD are at higher risk for abdominal surgery, but not for perianal surgery.

Predictors for Chronic Opioid Use in Patients With Inflammatory Bowel Disease: A Population-Based Cohort Study

INTRODUCTION

A significant proportion of patients with Crohn's disease (CD) and ulcerative colitis (UC) become opioid users, but data pertaining to predictors of chronic opioid use remain sparse. We examined predictors for chronic opioid use in CD/UC.

METHODS

This is a nationwide cohort study based on Danish registries, comprising incident patients with CD/UC (≥ 18 years) from January 1, 1996, to December 31, 2021. Chronic opioid use was defined as ≥ 1 prescriptions in at least 2 of 3 consecutive quarters. Cox regression models were used to estimate adjusted hazard ratios for predictors for chronic opioid use. Several variables and time-varying covariates (inflammatory bowel disease surgery, inflammatory bowel disease, and psychotropic medications) were included.

RESULTS

In 15,092 patients with CD, 4,141 (27.4%) became chronic opioid users (median follow-up 7.35 years, 25%-75% percentiles [interquartile range] 3.40-13.66 years). The 3 most important predictors were surgery (4.20, 95% confidence interval [CI] 3.72-4.75), hypnotics/sedatives (2.02, 95% CI 1.81-2.25), and age ≥ 50 years (1.92, 95% CI 1.77-2.09). In 30,416 patients with UC, 6,777 (22.3%) became chronic users (median follow-up 8.80 years, interquartile range 4.20-15.22 years). The 3 most important predictors were surgery (4.81, 95% CI 4.20-5.52), age ≥ 50 years (2.62, 95% CI 2.44-2.82), and hypnotics/sedatives (2.11, 95% CI 1.95-2.29).

DISCUSSION

An alarming proportion of patients became chronic opioid users. These results are helpful to risk stratify patients to prevent chronic opioid use. Clinicians should be particularly attentive in patients who have had surgery, who use hypnotics/sedatives, and who are elderly. We need evidence regarding pain management strategies, efficacy of nonopioid analgesics, and opioid cessation strategies.

Children and Adolescents Diagnosed With Inflammatory Bowel Disease Are at Increased Risk of Developing Diseases With a Possible Autoimmune Pathogenesis

BACKGROUND

The development of diseases with a possible autoimmune pathogenesis is common in adults with inflammatory bowel disease (IBD). In early onset IBD, it may differ but the evidence is sparse. We aimed to investigate the risk and time span from IBD diagnosis to outcomes with different associated disorders with possible autoimmune pathogenesis.

METHODS

A register-based study included all Danish patients with early onset of IBD (≤18 years) between 1980 and 2021 and 50 matched references without IBD for each case. We examined the risk of type 1 and type 2 diabetes, celiac disease, thyroid disease, rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis in Cox regression models.

RESULTS

In total, 6822 patients with IBD were identified, and 337 728 matched references. The median age at the time of IBD diagnosis or index date for the matched references was 16 years (25-75 percentile: 13-18 years), and the median age at the time of an outcome or at the end of follow-up was 28.1 years (25-75 percentile: 21.5-37.0 years). According to the cumulative incidence plots psoriatic arthritis, and spondyloarthritis was diagnosed approximately 10 years after the IBD onset, and the remaining outcomes later. The adjusted hazard ratio after full follow-up was 4.72 (95% CI, 3.85-5.80) for psoriatic arthritis, 5.21 (95% CI, 4.17-6.50) for spondyloarthritis, 2.77 (95% CI, 1.92-4.00) for celiac disease, 2.15 (95% CI, 1.54-3.01) for rheumatoid arthritis, 1.69 (95% CI, 1.23-2.32) and 1.64 (95% CI, 1.21-2.21) for type 1 and type 2 diabetes, respectively. For thyroid disease, it was 1.16 (95% CI, 0.97-1.40).

CONCLUSIONS

The risk estimates were significantly increased for all outcomes at the end of follow-up, except for thyroid disease, but according to the cumulative incidence plots, only psoriatic arthritis and spondyloarthritis occurred earlier in the IBD cohort than in the matched references.

Early-Life Infections, Antibiotics and Later Risk of Childhood and Early Adult-Onset Inflammatory Bowel Disease: Pooled Analysis of Two Scandinavian Birth Cohorts

BACKGROUND

Childhood antibiotic use has been associated with inflammatory bowel disease (IBD), although the potential contribution of infection frequency remains uncertain.

AIMS

To explore the association between early-life infections, antibiotics and IBD development.

METHODS

We used population-based data from ABIS (Sweden) and MoBa (Norway) cohorts following children from birth (1997-2009) until 2021. Prospectively collected questionnaires identified infection frequency (any, gastrointestinal and respiratory) and antibiotics (any, penicillin and non-penicillin) until age 3. IBD diagnosis required ≥ 2 records in national health registries. Cohort-specific hazard ratios (aHR), adjusted for parental education, smoking and IBD were estimated and pooled using a random-effects model. Antibiotic analyses were adjusted for infection frequency.

RESULTS

There were 103,046 children (11,872 ABIS and 91,174 MoBa), contributing to 1,663,898 person-years of follow-up, during which 395 were diagnosed with IBD. The frequency of any infection at 0 to < 1 and 1 to < 3 years showed a pooled aHR of 1.01 (95% confidence interval [CI] = 0.96-1.07) and 1.00 (95% CI = 0.99-1.01) per additional infection for IBD. Adjusting for infections, any versus no antibiotics in the first year was associated with IBD (pooled aHR = 1.33 [95% CI = 1.01-1.76]). The aHR for additional antibiotic course was 1.17 (95% CI = 0.96-1.44), driven by penicillin (per additional course, aHR = 1.28 [95% CI = 1.02-1.60]). Although antibiotics at 1 to < 3 years did not show an association with IBD or Crohn's disease, non-penicillin antibiotics were associated with ulcerative colitis (per additional course, aHR = 1.95 [95% CI = 1.38-2.75]).

CONCLUSION

Early-life antibiotic use was, a significant risk factor for childhood and early adult-onset IBD, independent of infection frequency.

Meta-Analysis: Prevalence of Frailty and Associated Adverse Events in Inflammatory Bowel Diseases

BACKGROUND

The number of adults aged over 60 years with inflammatory bowel disease (IBD) is increasing. Frailty, rather than chronological age, may be a better predictor of adverse health outcomes.

AIMS

To summarise current knowledge about frailty in adults with IBD including the prevalence and associations of frailty and IBD-related adverse outcomes.

METHODS

We performed an electronic search of MEDLINE, EMBASE and EMBASE Classic databases using search terms for IBD and frailty from inception to 14 February 2024. All studies involving adults aged ≥ 16 with a confirmed diagnosis of IBD that included a frailty assessment were eligible for inclusion.

RESULTS

We included 23 observational studies involving 1,893,448 adults. Risk of bias was low for 18 studies and moderate for five. Twelve methods of frailty assessment were used, the most common being the Hospital Frailty Risk Score. Pooled prevalence of frailty in IBD patients was 18% (95% confidence interval (CI) 12.4%-25.6%). Meta-analysis of unadjusted events data demonstrated that frailty increased the risk of infection-related admissions following treatment in two studies (relative risk (RR) 1.9; 95% CI 1.2-3.0), post-operative morbidity in three (RR 2.0; 95% CI 1.4-2.7) and mortality in seven (RR 4.3; 95% CI 2.6-7.4).

CONCLUSIONS

Frailty is common in patients with IBD and is associated with IBD-related adverse outcomes including infection-related admissions following treatment, post-operative morbidity and death. Future work should focus on developing risk assessment tools to better support decision making for older people with frailty and IBD.

Health-care resource use and costs associated with inflammatory bowel disease in northwest London: a retrospective linked database study

BACKGROUND

With 20-40% of patients who have inflammatory bowel disease (IBD) not responding to therapy, resource use and costs can be high. We performed a descriptive analysis of health-care data for IBD management in the National Health Service to explore potential areas for improvement.

METHODS

In this exploratory study, we analysed real-world data from the Discover dataset for adults with a diagnosis of incident IBD recorded in northwest London, UK, between 31 March, 2016, and 31 March, 2020. We compared mean visit numbers and primary and secondary care costs per patient to examine resource use and costs for active disease versus remission.

RESULTS

We included 7,733 patients (5,872 with ulcerative colitis [UC], 1,427 with Crohn's disease [CD], and 434 with codes for both [termed IBD-undefined in this study]). Remission was recorded in 19,218 (82%) of 23,488 observations for UC, 4,686 (82%) of 5,708 for CD, and 1,122 (65%) for IBD-undefined observations. Health-care resource use was significantly higher with active disease in all settings except primary care for UC. Total health-care costs were greater with active disease than remission for all diagnoses (all p < 0.0001). The main driver of costs was inpatient hospital care among those with active disease; elective inpatient costs were high among patients with UC and IBD-undefined in remission.

CONCLUSIONS

Higher health-care resource use and costs were observed with active disease, which underscores the importance of early induction and maintenance of remission in UC and CD. Updated strategies that incorporate treat to target may offer cost benefits by the offsetting of biologic drug costs with a reduction in costly inpatient hospital stays.

TRIAL REGISTRATION

This trial was not registered as it used pseudonymised retrospective data.

Differences in Clinical Practice and Disease Course Between Elderly-Onset and Long-Standing Elderly Ulcerative Colitis: A Single-Center Study in Japan

The optimal immunosuppressive therapy for elderly patients with ulcerative colitis (UC) remains unclear. We aimed to evaluate clinical practice and prognosis in elderly patients with UC through comparing between those with elderly-onset UC (EOUC) and those with long-standing elderly UC (LEUC). In this retrospective single-center cohort study, we evaluated elderly patients with UC aged ≥ 60 in August 2022 through collecting medical record data from the time of diagnosis of UC until August 2022. The patients were divided into two groups based on age at disease onset: EOUC (age at onset, ≥ 60 years) and LEUC (age at onset, < 60 years). We assessed the cumulative rates of systemic steroid and molecular targeted drug (MTD) initiation, and colectomy. We enrolled 97 eligible patients (EOUC group, n = 30; LEUC group, n = 67). The cumulative rates of initiating systemic steroid (46% vs. 22% at 1 year, respectively; P = 0.002) and MTD (17% vs. 5% at 1 year, respectively; P = 0.002) were higher in the EOUC group than in the LEUC group. In multivariate analysis, elderly onset was significantly associated with systemic steroid (hazard ratio [HR] 2.74, 95% confidence interval [CI] 1.43-5.29; P = 0.003) and MTD (HR 2.76, 95% CI 1.30-5.87; P = 0.008) initiation. Cumulative colectomy rates did not differ significantly between the two groups. Patients with EOUC were initiated on systemic steroids and MTDs sooner following disease onset than patients with LEUC. Our findings suggest rapid progression and refractoriness in patients with EOUC.

Characterization of Inflammatory Bowel Disease in the Elderly According to Age of Onset

Background/Objectives: Elderly populations are under-represented in inflammatory bowel disease (IBD) clinical trials, with limited data on phenotype, treatment patterns, outcomes, and comorbidities. The main objective of this study was to evaluate, in an elderly cohort with IBD, demographic and disease characteristics, comorbidity, polypharmacy, and treatment patterns according to the development of IBD at or before old age. Secondarily, the same analysis was performed based on the type of IBD: ulcerative colitis (UC) or Crohn's disease (CD). Materials and Methods: Observational, single-center, retrospective study including patients diagnosed with IBD and aged 65 years or older seen at the IBD office of the Regional University Hospital of Malaga between September and November 2022. Data were recorded on demographic, disease-related, and IBD treatment-related variables, comorbidities, and polypharmacy. A descriptive and analytical study was undertaken according to the age of IBD onset and type of IBD. Results: Of the patients included, 50.8% were male, 55.1% had CD, and 44.9% UC. IBD onset was before age 65 years in 69.5% and ≥65 years in 30.5%. Elderly with IBD who debuted <65 presented longer disease duration (19.67 ± 9.82 years) and required more IBD-related surgeries (37.8%); elderly with IBD who debuted ≥65 were older (77.69 ± 6.26 years), with no differences in the other variables. According to the type of IBD, elderly UC patients were older (74.55 ± 6.9 years), used more aminosalicylates (77.4%), and had higher rates of polypharmacy (90.6%). Elderly patients with CD had higher IBD activity (moderate/severe in 72.3%), used more biologic drugs (58.5%), and required more IBD-related surgeries (44.6%). Conclusions: Elderly patients who develop IBD before or after the age of 65 years are overall very similar in baseline and disease-related characteristics. Elderly with CD have higher IBD activity and require more biologic drugs and IBD-related surgeries. Elderly with UC are older and have higher rates of polypharmacy and aminosalicylate use.

Monitoring-Based Model for Personalizing Fecal Incontinence in Patients With Crohn's Disease: A Multicenter Inception Cohort Study

BACKGROUND AND AIMS

Fecal incontinence (FI) is a common complaint that greatly affects the quality of life of patients with Crohn's disease (CD) and is associated with the clinical characteristics of CD. We aimed to identify risk factors related to FI and construct a risk prediction model for FI in patients with CD.

METHODS

This retrospective study included 600 Chinese patients with CD from 4 IBD centers between June 2016 and October 2021. The patients were assigned to the training (n = 480) and testing cohorts (n = 120). Two nomograms were developed based on the logistic regression and Cox regression models to predict the risk factors for FI in patients with CD. The discriminatory ability and accuracy of the nomograms were evaluated using the receiver operating characteristic (ROC) curves and the area under the ROC curves (AUCs). Additionally, the Kaplan-Meier survival curve was also used further to validate the clinical efficacy of the Cox regression model.

RESULTS

The overall prevalence of FI was 22.3% (n = 134 of 600). In the logistic regression model, age at diagnosis (odds ratio [OR], 1.032; P = .033), penetrating behavior of disease (OR, 3.529; P = .008) and Perianal Disease Activity Index score >4 (OR, 3.068; P < .001) were independent risk factors for FI. In the Cox regression model, age at diagnosis (hazard ratio [HR], 1.027; P = .018), Montreal P classification (HR, 2.608; P = .011), and Perianal Disease Activity Index score >4 (HR, 2.190; P = .001) were independent predictors of the prevalence of FI over time. Two nomograms were developed to facilitate risk score calculation, and they showed good discrimination ability according to AUCs.

CONCLUSIONS

In this study, we identified 4 risk factors related to the prevalence of FI and developed 2 models to effectively predict the risk scores of FI in CD patients, helping to delay the course of FI and improve the prognosis with timely intervention.

Impact of musculoskeletal joint complaints on quality of life in patients with inflammatory bowel disease: a cross-sectional study

BACKGROUND

Musculoskeletal joint complaints (MSCs) are the most common extraintestinal manifestation of inflammatory bowel disease (IBD). We aimed to investigate the effect of MSC on the health-related quality of life (QoL) in patients with IBD.

DESIGN

A survey-based cross-sectional study among adult Dutch IBD patients.

SETTING

Primary care, secondary care and patient association.

PARTICIPANTS

In total, 635 IBD patients were included. The mean age was 46.3 (SD 14.2) years, and 35% were male.

OUTCOME

MSC was defined as suffering from any joint complaints. QoL was measured using the IBD questionnaire and a 36-item short form health survey questionnaire.

METHODS

A univariate analysis was performed to estimate the impact of various factors, such as demographic characteristics, setting, type of IBD and fatigue, which was followed by a multiple regression analysis to adjust for the confounding factors.

RESULTS

Of the 635 IBD patients, 332 suffered from Crohn's disease (CD) and 303 from ulcerative colitis (UC). After adjusting for confounding factors, MSC was independently associated with reduced QoL among IBD patients (β=-10.6, 95% CI -15.2 to -6.1), both in CD (β=-8.3, 95% CI -14.6 to -2.1) and UC (β=-13.9, 95% CI -20.5 to -7.3). 11% of the IBD patients had a rheumatological diagnosis. QoL in these patients was significantly lower compared with IBD patients with non-rheumatological MSC.

CONCLUSIONS

IBD patients with MSC are associated with a lower QoL, explicitly in patients with a rheumatological diagnosis. Prospective research is necessary to evaluate the causality and suitable interventions to increase QoL in these multimorbid patients.

Inflammatory Bowel Disease in Adults and Elderly: The Use of Selected Non-IBD Medication Examined in a Nationwide Cohort Study

BACKGROUND

Real-world data on medications used for conditions other than inflammatory bowel disease (IBD) are sparse. We examined how the onset of IBD affects the prescription pattern of selected non-IBD medication and the risk of becoming an incident user.

METHODS

This nationwide cohort study utilized data from Danish health registers. We included incident patients with young adult-onset IBD (18-39 years of age), adult-onset IBD (40-59 years of age), and elderly-onset IBD (60+ years of age), from 1998 to 2018 and followed all for 3 years. We examined redeemed prescriptions before and after the onset of IBD and estimated the risk of becoming a user of non-IBD medications using logistic regression models.

RESULTS

We identified 36165 patients, 16 771 (46%) with young adult onset, 10615 (29%) with adult onset, and 8779 (24%) with elderly onset. The onset of IBD increased the use of antidepressants, antipsychotics, sedatives/hypnotics, opioids, nonopioid analgesics, antidiabetics, and proton pump inhibitors, even in patients with no other underlying comorbid diseases. The adjusted odds ratio for using antidepressants 1 year after the onset of IBD in elderly was 1.50 (95% confidence interval [CI], 1.14-1.82), in opioids 1.69 (95% CI, 1.45-1.95), in nonopioid analgesics 2.10 (95% CI, 1.77-2.48), in cardiovascular medication 2.20 (95% CI, 1.86-2.61), and in proton pump inhibitors 1.51 (95% CI, 1.31-1.74) compared with adults.

CONCLUSIONS

In all 3 age groups, the proportions of patients with redeemed prescriptions for several groups of non-IBD medication were significantly increased after the IBD diagnosis compared with before. The risk of becoming an incident user for several groups of non-IBD medication was increased in elderly patients.

Risk of Kidney Failure in Patients With Inflammatory Bowel Disease Undergoing Colectomy: A Nationwide Cohort Study

BACKGROUND & AIMS

Inflammatory bowel disease (IBD) is frequently accompanied by kidney complications. Potential triggers or subpopulations at high-risk of kidney problems are not well-elucidated. We hypothesized that surgical interventions, specifically colectomy, might in part explain this risk.

METHODS

This study was a nationwide Swedish cohort study comprising 82,051 individuals with biopsy-proven IBD diagnosed during 1965 to 2017, with follow-up until 2019. We investigated the association between incident colectomy (time-varying exposure) and future risk of acute kidney injury (AKI) and kidney failure (diagnosis of end-stage kidney disease or death due to chronic kidney disease) using Cox proportional hazard models. We also examined the impact of partial vs total colectomy and the presence/duration of a stoma. Covariates included demographics, education level, and selected comorbidities.

RESULTS

Over a median follow-up of 14 years, 16,479 individuals underwent colectomy, and 2556 AKI and 1146 kidney failure events occurred. Colectomy was associated with an increased relative risk of both AKI (adjusted hazard ratio, 2.37; 95% confidence interval, 2.17-2.58) and kidney failure (adjusted hazard ratio, 1.54; 95% confidence interval, 1.34-1.76). Compared with pre-colectomy periods, undergoing total colectomy and colectomy with prolonged stoma showed higher risks of both kidney outcomes versus partial colectomy or colectomy with a temporary stoma, respectively. Subgroup analyses suggested higher risks in patients with ulcerative colitis.

CONCLUSIONS

In people with IBD, rates of AKI and kidney failure are higher among those undergoing colectomy, particularly among those following total colectomy, or colectomy with a prolonged stoma. This study identifies a high-risk population that may benefit from established protocols for kidney function monitoring/surveillance and referral to nephrologist care.

Considerations on Multimorbidity and Frailty in Inflammatory Bowel Diseases

There are growing numbers of older people with inflammatory bowel diseases [IBD]. These older patients are more likely to have other comorbidities and polypharmacy, which can make recognizing and treating IBD complex. Frailty is a newer concept in the IBD field, and we are beginning to recognize the importance of this as a marker of biological age and its association with risk of adverse IBD-related outcomes. In this review article we aim to provide practical insight into the specific challenges facing older patients and their clinicians at each stage of the patient journey. We also discuss the latest understanding of the impact of frailty for these patients with IBD and highlight areas for future research.

Childhood Socioeconomic Characteristics and Risk of Inflammatory Bowel Disease: A Scandinavian Birth Cohort Study

BACKGROUND

Ecological observations suggest a negative relationship between childhood socioeconomic status (SES) and inflammatory bowel disease (IBD) risk. Individual-level analyses have been inconsistent and mostly lacked refined assessments of SES. We aimed to comprehensively study the association between early-life SES and later IBD.

METHODS

This study included 117 493 participants from the Norwegian Mother, Father and Child cohort and Swedish All Babies in Southeast Sweden cohorts. Participants were followed from birth (1997-2009) through 2021. IBD was identified through national patient registers. Questionnaire and register data were used to define parental educational level, employment, and household income level. Cox regression estimated adjusted hazard ratios (aHRs), accounting for other SES exposures and covariates (eg, parental IBD). Cohort-specific estimates were pooled using a random-effects model.

RESULTS

During 2 024 299 person-years of follow-up, 451 participants were diagnosed with IBD (All Babies in Southeast Sweden cohort, n = 113 and Norwegian Mother, Father and Child cohort, n = 338). Early-life maternal, but not paternal, educational level was associated with later IBD (low vs high educational level; pooled aHR, 1.81; 95% confidence interval [CI], 1.16-2.82; and pooled aHR, 1.20; 95% CI, 0.80-1.80; respectively). Having a nonworking mother or father was not significantly associated with IBD (pooled aHR, 0.69; 95% CI, 0.47-1.02; pooled aHR, 0.79; 95% CI, 0.45-1.37). High vs low household income level yielded a pooled aHR of 1.33 (95% CI, 0.94-1.89). Overall, results were largely consistent across cohorts.

CONCLUSIONS

In this prospective Scandinavian cohort study, low maternal educational level was, independent of other SES and covariates, significantly associated with later IBD in her child. Further research is needed to elucidate factors that may mediate this relationship.

New Surgery and Hospital-diagnosed Infections in Elderly Patients with Inflammatory Bowel Disease Undergoing Surgery: A Nationwide Cohort Study

BACKGROUND

Elderly patients with inflammatory bowel disease [IBD] are fragile in many respects. Therefore, in these patients, we studied postoperative complications [new abdominal surgery and serious infections after the first IBD surgery].

METHODS

This is a nationwide cohort study based on Danish health registries and included patients with IBD undergoing surgery. The study population was split into ulcerative colitis [UC] and Crohn's disease [CD]. The exposed cohort [elderly] constituted those at an age of ≥60 years at first IBD surgery, and the unexposed [adults] those with surgery at the age of 18-59 years. We estimated adjusted hazard ratios [aHRs] of: a] new abdominal surgery within 2 years; and b] serious [hospital-diagnosed] infections within 6 and 12 months. We adjusted for several confounders including type of index surgery [laparoscopic or open].

RESULTS

The aHR for a new surgery among elderly with UC and CD were 0.69 [95% CI 0.58-0.83] and 0.98 [95% CI 0.83-1.15], respectively. In elderly with UC, the aHRs of infections within 6 and 12 months after surgery were 1.07 [95% CI 0.81-1.40] and 0.85 [95% CI 0.67-1.08], respectively. In the elderly with CD, the aHRs of infections within 6 and 12 months were 1.45 [95% CI 1.12-1.88] and 1.26 [95% CI 1.00-1.59], respectively.

CONCLUSION

The elderly with IBD did not have an increased risk of new abdominal surgery within 2 years of the first surgery. Elderly with CD, but not UC, had an increased risk of serious infections within 6 months of surgery.

Frailty risk and treatment strategy in elderly-onset inflammatory bowel disease. A Norwegian nationwide population-based registry study

BACKGROUND/AIMS

To determine real-world medical and surgical treatment patterns in elderly-onset inflammatory bowel disease in a nationwide cohort, and to investigate associations between frailty and treatment choices.

METHODS

Norwegian health registries were used to identify adult-onset (born 1950-1989) and elderly-onset (born 1910-1949) patients with Crohn's disease (CD) and ulcerative colitis (UC) diagnosed 2010-2017 (n = 13,006). Patients were classified as no, low and intermediate/high frailty risk after the Hospital Frailty Risk Score. Outcomes included use of medical and surgical treatment.

RESULTS

Within five years, elderly-onset patients received less biologics (13% [CD], 7% [UC]) and immunomodulators (24% [CD], 11% [UC]), and major surgery was more frequent (22% [CD], 9% [UC]) than in adult-onset. Respective log rank tests were significant (p < 0.01). Compared to no frailty risk groups, elderly-onset UC with intermediate/high frailty risk had lower probability of starting biologics (4% versus 9%), immunomodulators (7% versus 13%) and 5-aminosalisylic acids (66% versus 84%), and elderly-onset CD with intermediate/high frailty risk had higher probability of starting prednisolone (67% versus 49%). Respective log rank tests were significant (p < 0.05).

CONCLUSIONS

Elderly-onset patients received less biologics and immunomodulators and a larger proportion underwent major surgery. Frailty risk in elderly-onset patients was associated with increased use of prednisolone, and less use of 5-aminosalisylic acids, immunomodulators and biologics.

Treatment of inflammatory bowel disease with steroid-sparing medications is age-dependent - Results from a Danish nationwide cohort study, 2000-2018

BACKGROUND

Paediatric-onset and elderly-onset inflammatory bowel disease (IBD) present unique treatment challenges.

AIMS

We investigated treatment patterns following a first and second course of systemic steroids in paediatric- and elderly-onset IBD and compared them to adult-onset IBD.

METHODS

All patients diagnosed with Crohn's disease (CD) or ulcerative colitis (UC) between 2000 and 2018 were identified through the Danish healthcare registries. Patients were divided into groups based on their age at diagnosis. Kaplan-Meier plots were prepared for medications and surgeries after diagnosis and after the first and second courses of systemic steroids. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated using multivariate Cox regression analysis for steroid-sparing medications.

RESULTS

1851 CD (13%) and 1687 (6%) UC patients were paediatric-onset, while 2952 (20%) CD and 5812 (23%) UC patients were elderly-onset. Paediatric-onset more frequently received immunomodulators [CD: HR: 1.64, CI: 1.52-1.77, UC: HR: 2.29, CI: 2.02-2.61] and biologics [CD: HR: 1.43, CI: 1.25-1.65, UC: HR: 1.27, CI: 0.99-1.64], while elderly-onset less frequently received immunomodulators [CD: HR: 0.39, CI: 0.35-0.44, UC: HR: 0.58, CI: 0.50-0.67] and biologics [CD: HR: 0.19, CI: 0.14-0.25, UC: HR: 0.36, CI: 0.27-0.48] compared to adult-onset age groups. After two courses of systemic steroids, elderly-onset still received less steroid-sparing medications. High frailty was associated with lower usage of medications for elderly-onset.

CONCLUSION

There are significant differences in the use of steroid-sparing medication between age of onset, even after two courses with systemic steroids. High frailty could account for some of these differences in elderly-onset IBD.

Risk of heart failure in inflammatory bowel disease: a Swedish population-based study

BACKGROUND AND AIMS

Dysregulation of inflammatory and immune responses has been implicated in the pathogenesis of heart failure (HF). But even if inflammation is a prerequisite for inflammatory bowel disease (IBD), little is known about HF risk in IBD.

METHODS

In this Swedish nationwide cohort, patients with biopsy-confirmed IBD were identified between 1969 and 2017 [n = 81 749, Crohn's disease (CD, n = 24 303), ulcerative colitis (UC, n = 45 709), and IBD-unclassified (IBD-U, n = 11 737)]. Each patient was matched with up to five general population reference individuals (n = 382 190) and IBD-free full siblings (n = 95 239) and followed until 31 December 2019. Flexible parametric survival models estimated the adjusted hazard ratio (aHR) and standardized cumulative incidence for HF, with 95% confidence intervals (CI).

RESULTS

There were 5582 incident HF identified in IBD patients (incidence rate [IR]: 50.3/10 000 person-years) and 20 343 in reference individuals (IR: 37.9) during a median follow-up of 12.4 years. IBD patients had a higher risk of HF than reference individuals (aHR 1.19, 95% CI 1.15-1.23). This increased risk remained significant ≥20 years after IBD diagnosis, leading to one extra HF case per 130 IBD patients until then. The increased risk was also observed across IBD subtypes: CD (IR: 46.9 vs. 34.4; aHR 1.28 [1.20-1.36]), UC (IR: 50.1 vs. 39.7; aHR 1.14 [1.09-1.19]), and IBD-U (IR: 60.9 vs. 39.0; aHR 1.28 [1.16-1.42]). Sibling-controlled analyses showed slightly attenuated association (IBD: aHR 1.10 [1.03-1.19]).

CONCLUSIONS

Patients with IBD had a moderately higher risk of developing HF for ≥20 years after IBD diagnosis than the general population.

ASSESSMENT OF QUALITY OF LIFE IN ELDERLY PATIENTS WITH INFLAMMATORY BOWEL DISEASE WITH MILD ACTIVITY AND IN CLINICAL REMISSION

BACKGROUND

Inflammatory bowel disease (IBD), represented by Crohn's disease (CD) and ulcerative colitis (UC), is a chronic condition that affects all age groups, predominantly in young individuals. Currently, an increase in the prevalence of IBD has been documented, in parallel with the increase in the elderly population. The scarce number of studies that better characterize the impact of IBD on Quality of Life (QoL) in the elderly motivated the present study.

OBJECTIVE

To evaluate the impact of IBD on the QoL of elderly people treated at a Tertiary IBD Center.

METHODS

Prospective cross-sectional study that included elderly patients (age ≥60 years) with quiescent or mildly active IBD treated at the HU-UFJF IBD Center between March 2019 and December 2022. Elderly companions without severe comorbidities who attended the consultation with the patients were included as a control group. Sociodemographic and IBD-related characteristics were recorded. QoL was assessed using previously validated questionnaires (WHOQOL-BREF and IBDQ). Patients with IBD with moderate to severe activity, history of recent or imminent hospitalization, serious or opportunistic infections in the last 6 months, previous neoplasia, dementia, and difficulty understanding/fulfilling the questionnaires were excluded.

RESULTS

A total of 123 patients were included (74 with IBD and 49 in the control group), with a mean age of 67±6.2 years, 52.7% with CD, and 47.3% with UC. Mild disease activity was observed in 31.1%. Both groups (IBD patients and control) were comparable based on age, sex, BMI, and the Charlson Comorbidity Index. Patients with IBD and controls had similar QoL scores in the different domains assessed by the WHOQOL-BREF. On the other hand, when evaluating the general facet of QoL, IBD patients had significantly lower scores in General QoL (3.71±0.87 versus 4.02±0.62, respectively; P=0.021) and General Health (3.32±1.05 versus 3.69±0.94, respectively; P=0.035). The presence of mildly active IBD negatively impacted the general health score (2.91±0.99 versus 3.47±1.04, respectively; P=0.035) and the physical domain of the WHOQOL-BREF (12.27±2.63 versus 13.86±2.61, respectively; P=0.019) when compared to patients in remission. Conversely, no impact on QoL was observed with the Application of the IBDQ questionnaire regarding the type of the disease (161±38.5 versus 163.1±42.6 for CD and UC, respectively; P=0.84) or the presence of activity (152.5±38.8 versus 166.4±40.5, respectively; P=0.17).

CONCLUSION

No statistically significant differences were found between elderly patients with mildly active or quiescent IBD and elderly patients without IBD when observing global QoL scores. However, IBD negatively impacted the general facet of QoL, just as mild activity was associated with lower scores in general health and the physical domain assessed by the WHOQOL-BREF. Patients with IBD treated with biological therapy had better Qol than those on conventional therapy. Future studies are needed to choose the most appropriate tool for assessing QoL in this population.

Global patterns in the epidemiology, cancer risk, and surgical implications of inflammatory bowel disease

Inflammatory bowel disease (IBD), mainly including ulcerative colitis and Crohn's disease, imposes a huge medical and economic burden worldwide. Recently, the diagnosis, treatment, and surveillance of IBD have advanced rapidly, which has changed the epidemiology, cancer risk, and surgery risk of IBD. Here, we reviewed the recent literature on the epidemiology, IBD-related cancer, and IBD-related surgery. We created a choropleth map to show the worldwide incidence trend for Crohn's disease and ulcerative colitis. We also found that the cancer risk and surgery risk of IBD are declining and discussed some risk factors associated with them. Based on the recent trend, we proposed several suggestions and hoped to reduce the global burden of IBD as far as possible.

Atopic Dermatitis in Early Childhood and Risk of Inflammatory Bowel Disease: A Scandinavian Birth Cohort Study

OBJECTIVE

To examine the association between early-life atopic manifestations and later risk of inflammatory bowel disease (IBD), for which prospective data are scarce.

STUDY DESIGN

The population-based All Babies in Southeast Sweden (ABIS) and Norwegian Mother, Father, and Child (MoBa) cohorts follow children from birth (ABIS 1997-1999; MoBa 2000-2009) to the end of 2021. Based on validated questionnaires, parents prospectively reported information on asthma, food-related allergic symptoms, atopic dermatitis, and allergic rhinitis by age 3. IBD was defined by ≥ 2 diagnostic records in the national health registries. Cox regression estimated hazard ratios adjusted (aHRs) for parental IBD, atopy, education level, smoking habits, and national origin. Cohort-specific estimates were pooled using a random-effects model.

RESULTS

We compiled data on 83 311 children (ABIS, n = 9041; MoBa, n = 74 270). In over 1 174 756 person-years of follow-up, 301 participants were diagnosed with IBD. Children with atopic dermatitis at age 3 had an increased risk of IBD (pooled aHR = 1.46 [95% CI = 1.13-1.88]), Crohn's disease (pooled aHR = 1.53 [95%CI = 1.04-2.26]), and ulcerative colitis (pooled aHR = 1.78 [95%CI = 1.15-2.75]). Conversely, any atopic manifestation by age 3 was not associated with IBD (pooled aHR = 1.20 [95%CI = 0.95-1.52]), nor were analyses specifically focused on early-life food-related allergic symptoms, asthma, and allergic rhinitis.

CONCLUSION

While atopic manifestations in early childhood were overall not associated with IBD, children with atopic dermatitis specifically were at increased risk of developing IBD, suggesting shared etiologic traits; these findings might be useful in identifying at-risk individuals for IBD.

The use of opioids nine months after surgery for Crohn's disease - a nationwide cohort study

BACKGROUND

The risk of chronic opioid use after surgery for Crohn's disease (CD) is not known.

AIM

The aim of this study is to examine the chronic opioid use after surgery according to age at time of surgery and to opioid use prior to surgery.

METHODS

This nationwide cohort study included patients with a first surgery for CD (January 1, 1996 through 2021). We examined prescribed opioids 9 months after surgery and estimated adjusted odds ratios (OR) for chronic opioid use in elderly (≥60 years), adults (≥40 and <60 years), and young adults (≥18 and <40 years) according to opioid use prior to surgery. Chronic opioid use was defined as prescriptions in at least two of three consecutive quarters.

RESULTS

A total of 797 patients had surgery as elderly, 1603 as adults, and 2786 as young adults. Across all age groups, 18%-38% received opioid prescriptions throughout 9 months after surgery, if opioids were prescribed prior to surgery. If opioids were not prescribed prior to surgery, the corresponding proportions were 2%-5%. If patients were prescribed opioids (≥1) prior to surgery, the adjusted ORs (95% CIs) for their chronic use after surgery in elderly, adults, and young adults were 10.37 (6.77-15.88), 10.48 (7.74-14.19), and 6.55 (4.93-8.72), respectively.

CONCLUSION

Clinicians should be aware that in patients with a need for opioids before surgery, the surgery may not change the need for opioids. Future research should examine effective analgesic strategies that help minimise opioid use in this population.

Paediatric-onset immune-mediated inflammatory disease is associated with an increased mortality risk-A nationwide study

BACKGROUND

Paediatric-onset immune-mediated inflammatory diseases (pIMID) show more aggressive phenotypes than when diagnosed in adults. However, data on mortality are often extrapolated from adult studies.

AIM

To estimate the effect of pIMID on mortality.

METHODS

In a population-based cohort study using the nationwide Danish healthcare registers, we included all patients diagnosed with pIMID in Denmark from 1980 to 2018. PIMID were defined as ICD codes indicative of autoimmune hepatitis, primary sclerosing cholangitis, Crohn's disease, ulcerative colitis, juvenile idiopathic arthritis, lupus erythematosus, or vasculitis registered before age 18 years. All-cause mortality was the primary outcome; cause-specific mortality was the secondary outcome. We used Cox survival analysis to estimate hazard ratios (HR), and Aalen survival analysis to estimate rate differences.

RESULTS

We included 11,581 individuals diagnosed with pIMID and 99,665 reference individuals, accounting for 1,371,994 person-years of follow-up. Median and interquartile (IQR) age at diagnosis was 12.6 (7.9-15.9) years. During follow-up, 152 patients with pIMID and 316 reference individuals died; adjusted HR (aHR) was 3.8 (95% confidence interval [CI] 3.1-4.7). This corresponded to 6.9 (95% CI: 5.3-8.5) additional deaths per 10,000 person-years. The strongest associations were found for gastrointestinal diseases (aHR 22.8; 95% CI 9.6-64.1), gastrointestinal cancers (aHR 19.2; 95% CI 5.0-74.2) and lymphoproliferative disorders (aHR 6.8; 95% CI 2.8-16.8).

CONCLUSION

Patients diagnosed with pIMID have a fourfold higher risk of mortality when followed into early adulthood compared with reference individuals. This underlines the severe disease course of pIMID and highlights the need for multidisciplinary care.

Impact of inflammatory bowel disease on the risk of acute coronary syndrome: A Swedish Nationwide Cohort Study

BACKGROUND

There are conflicting data on the risk of acute coronary syndrome (ACS) in patients with inflammatory bowel disease (IBD). Only a few previous reports include patients diagnosed during the last decade.

AIM

To assess and compare the risk of ACS between patients with IBD and the general population.

METHODS

In this cohort study, we used nationwide registers to identify patients diagnosed with IBD in Sweden 2003-2021. Every patient was matched by birth year, sex, calendar year and area of residence with up to 10 general population comparators. The primary outcome was incident ACS. We used semi-parametric Cox proportional hazard models to estimate hazard ratios (HRs).

RESULTS

We identified 76,517 patients with IBD (Crohn's disease [CD], N = 22,732; ulcerative colitis [UC], N = 42,194 and IBD-unclassified, N = 11,591) and 757,141 comparators. During a median follow-up of 8 years, 2546 patients with IBD (37.5/10,000 person-years) were diagnosed with ACS compared with 19,598 (28.0/10,000 person-years) among comparators (HR 1.30; 95% confidence interval 1.24-1.35) after adjustments for confounding factors, and approximately one extra case of ACS in 100 IBD patients followed for 10 years. The highest HRs for ACS were in patients with elderly onset IBD (≥60 years) and among patients with CD or UC with extra-intestinal manifestations. No increased HRs were observed in patients diagnosed with IBD before the age of 40.

CONCLUSION

In this contemporary cohort of patients with IBD, exposed to modern IBD care, there was an increased risk for ACS compared with individuals from the general population.

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.

Therapy in elderly IBD patients

INTRODUCTION

Appropriate treatment is critical in elderly inflammatory bowel disease (IBD) subjects since they are at higher risk of complications such as infections, malignancies and mortality.

EVIDENCE ACQUISITION

We conducted an extensive PubMed search for guidelines, systematic reviews and primary studies to perform a critical analysis of the existing literature on the efficacy and safety of conventional and biological therapies for elderly IBD patients.

EVIDENCE SYNTHESIS

Due to the exclusion of elderly population from clinical trials, most evidences comes from real-life studies. While aminosalicylates remain a cornerstone treatment of elderly patients with ulcerative colitis (UC), for their effectiveness and safety, their use in Crohn's disease (CD) should not be further supported. Corticosteroid use should be limited for the induction of remission, while as maintenance treatment it should be avoided, due to the low safety profile. Although as efficacious as in the younger population, immunosuppressant use has been associated with higher risk of infective/malignant issues and further use should be carefully evaluated. Biologics have demonstrated high effectiveness in the elderly. However, due to increased morbidity and mortality described in elderly subjects treated with anti-TNF alpha agents, vedolizumab and ustekinumab should be favoured over anti-TNF alpha agents.

CONCLUSIONS

Treatment of elderly IBD patients remains challenging, since comorbidities and the risk of adverse events can complicate the effectiveness and safety of therapy. Close monitoring of such patients in a multidisciplinary team is advocated to reduce the risk of infections and optimize the treatment, choosing a suitable agent.

Epidemiology and clinical course of late onset inflammatory bowel disease

With the increasing age of the general population in developed countries, the management of several chronic diseases becomes more and more complex due to comorbidities. Some, especially inflammatory bowel diseases, formerly believed to belong to the young adult population, have now been recognized as being present at disease onset also in the ageing population, representing medical challenges different from those in the younger population. In the past few years, knowledge on this special older population has increased, changing initial beliefs concerning epidemiology and course of disease. In the present review, we addressed the most recent evidence concerning their current incidence compared with other age groups, their clinical course, potential risk factors for the development of late-onset IBDs, associated diseases, and cancer risk beyond therapy-related neoplasias.

Older Adult-Onset of Inflammatory Bowel Diseases Is Associated With Higher Utilization of Analgesics: A Nationwide Cohort Study

INTRODUCTION

Patients with inflammatory bowel diseases (IBD) commonly require analgesic medications to treat pain, which may be associated with complications. We examined trends of analgesic use according to age at IBD onset.

METHODS

This nationwide cohort study included adults diagnosed with IBD between 1996 and 2021 in Denmark. Patients were stratified according to their age at IBD onset: 18-39 years (young adult), 40-59 years (adult), and older than 60 years (older adult). We examined the proportion of patients who received prescriptions for analgesic medications within 1 year after IBD diagnosis: strong opioids, tramadol, codeine, nonsteroidal anti-inflammatory drugs, and paracetamol. Multivariable logistic regression analysis was performed to examine the association between age at IBD onset and strong opioid prescriptions and the composite of strong opioid/tramadol/codeine prescriptions.

RESULTS

We identified 54,216 adults with IBD. Among them, 25,184 (46.5%) were young adults, 16,106 (29.7%) were adults, and 12,926 (23.8%) were older adults at IBD onset. Older adults most commonly received analgesic prescriptions of every class. Between 1996 and 2021, strong opioid, tramadol, and codeine prescriptions were stable, while paracetamol prescriptions increased and nonsteroidal anti-inflammatory drug prescriptions decreased. After multivariable logistic regression analysis, older adults had higher adjusted odds of receiving strong opioid prescriptions (adjusted odds ratio 1.95, 95% confidence interval 1.77-2.15) and the composite of strong opioid/tramadol/codeine prescriptions (adjusted odds ratio 1.93, 95% confidence interval 1.81-2.06) within 1 year after IBD diagnosis compared with adults.

DISCUSSION

In this nationwide cohort, older adults most commonly received analgesic prescriptions within 1 year after IBD diagnosis. Additional research is needed to examine the etiology and sequelae of increased analgesic prescribing to this demographic.

Crossing barriers: the burden of inflammatory bowel disease across Western Europe

An estimated 2.5-3 million individuals (0.4%) in Europe are affected by inflammatory bowel disease (IBD). Whilst incidence rates for IBD are stabilising across Europe, the prevalence is rising and subsequently resulting in a significant cost to the healthcare system of an estimated 4.6-5.6 billion euros per year. Hospitalisation and surgical resection rates are generally on a downward trend, which is contrary to the rising cost of novel medication. This signifies a large part of healthcare cost and burden. Despite publicly funded healthcare systems in most European countries, there is still wide variation in how patients receive and/or pay for biologic medication. This review will provide an overview and discuss the different healthcare systems within Western Europe and the barriers that affect overall management of a changing IBD landscape, including differences to hospitalisation and surgical rates, access to medication and clinical trial participation and recruitment. This review will also discuss the importance of standardising IBD management to attain high-quality care for all patients with IBD.

Preoperative Risk Factors for Adverse Events in Adults Undergoing Bowel Resection for Inflammatory Bowel Disease: 15-Year Assessment of the American College of Surgeons National Surgical Quality Improvement Program

INTRODUCTION

Older adults with inflammatory bowel disease (IBD) are at higher risk for postoperative complications as compared to their younger counterparts; however, factors contributing to this are unknown. We assessed risk factors associated with adverse IBD-related surgical outcomes, evaluated trends in emergency surgery, and explored differential risks by age.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program database, we identified adults ≥18 years of age who underwent an IBD-related intestinal resection from 2005 to 2019. Our primary outcome included a 30-day composite of mortality, readmission, reoperation, and/or major postoperative complication.

RESULTS

Overall, 49,746 intestinal resections were performed with 9,390 (18.8%) occurring among older adults with IBD. Nearly 37% of older adults experienced an adverse outcome as compared to 28.1% among younger adults with IBD ( P < 0.01). Among all adults with IBD, the presence of preoperative sepsis (adjusted odds ratio [aOR], 2.08; 95% confidence interval [CI] 1.94-2.24), malnutrition (aOR, 1.22; 95% CI 1.14-1.31), dependent functional status (aOR, 6.92; 95% CI 4.36-11.57), and requiring emergency surgery (aOR, 1.50; 95% CI 1.38-1.64) increased the odds of an adverse postoperative outcome, with similar results observed when stratifying by age. Furthermore, 8.8% of surgeries among older adults were emergent, with no change observed over time ( P = 0.16).

DISCUSSION

Preoperative factors contributing to the risk of an adverse surgical outcome are similar between younger and older individuals with IBD, and include elements such as malnutrition and functional status. Incorporating these measures into surgical decision-making can reduce surgical delays in older individuals at low risk and help target interventions in those at high risk, transforming care for thousands of older adults with IBD.

Physical activity in childhood and later risk of inflammatory bowel disease: A Scandinavian birth cohort study

BACKGROUND AND OBJECTIVE

Retrospective data have linked adult physical activity (PA) to reduced risk of inflammatory bowel disease (IBD). We aimed to prospectively examine the association of PA and screen time (ST) in childhood with later risk of IBD, for which data are scarce.

METHODS

Using two population-based birth cohorts (All Babies in Southeast Sweden [ABIS] and Norwegian Mother, Father, and Child Cohort Study [MoBa]), we retrieved parent-reported data on PA and ST degree at ages 3 and 8 years. Data were modelled as binary (high vs. low) and numerical (hours/day) exposures. Inflammatory bowel disease was defined as ≥2 diagnostic records in national health registers. Cox regression estimated hazard ratios adjusted for potential confounding from parental IBD, country of origin, education, and smoking habits (Adjusted hazard ratio (aHR)). Our 8-year analyses included a 2-year lag period to reduce the risk of reverse causation. Cohort-specific estimates were pooled using random-effects model.

RESULT

Among 65,978 participants from ABIS (n = 8810) and MoBa (n = 57,168) with available data, 266 developed IBD. At 3 years, children with high versus low PA had an aHR of 1.12 for IBD (95%CI = 0.87-1.43); high versus low ST showed an aHR of 0.91 (95%CI = 0.71-1.17). Conversely, at 8 years, high versus low ST was associated with increased risk of later IBD (aHR = 1.51; 95%CI = 1.02-2.25), but PA at 8 years, was not linked to IBD (aHR = 1.19; 95%CI = 0.80-1.76). Subtype-specific analyses for Crohn's disease and ulcerative colitis did not differ appreciably.

CONCLUSION

Acknowledging possible confounding variables, children with high versus low ST at 8 years were at increased risk of IBD. In contrast, PA degree was not linked to IBD at any age category.

Clinical outcomes amongst elderly patients with inflammatory bowel disease

BACKGROUNDS AND AIMS

Inflammatory bowel disease (IBD) affects a growing cohort of elderly patients. Our aim was to compare the quality of care received by elderly patients with IBD with a nonelderly adult IBD population using clinical markers including steroid-free clinical remission.

METHOD

Retrospective audit of all consecutive patients attending a specialist IBD centre over a 1-year period aged >60 (elderly cohort [EC]) and 50 consecutive patients aged 30-45 years (control cohort [CC]). A follow-up survey was completed assessing current symptoms and perceptions of care.

RESULTS

One hundred thirty-nine patients were evaluated (89 EC, 50 CC). Steroid-free clinical remission was observed less commonly in the EC (58, 64%) compared with the CC (40, 80%) (P < 0.05). Biologics such as infliximab (15% EC vs 36% CC; P < 0.01) and adalimumab (14% EC vs 30% CC; P = 0.02) were used less frequently in the EC, whilst vedolizumab (6% EC vs 6% CC; P = 1) and ustekinumab (3% EC vs 2% CC; P = 1) were used at a similar frequency. Patients in the EC were less likely to have specialist IBD nursing contact (P < 0.01), smoking screening (P < 0.011) or influenza vaccinations (P < 0.006). IBD nurse contact was associated with significantly greater provision of the preventative care measures.

CONCLUSION

Elderly patients with IBD were less likely to experience steroid-free clinical remission or be prescribed biologics. Elderly patients were less likely to receive education with respect to preventative medicine. The models of care for the elderly need re-evaluation and greater incorporation with the multidisciplinary IBD team.

Optimizing individualized management of patients with ulcerative colitis: Identification of risk factors predicting ulcerative colitis-associated neoplasia

The risk of developing colorectal neoplasia in patients with ulcerative colitis (UC) is increased. The purpose of this study is to analyze the risk factors of UC-associated neoplasia (UCAN) in UC patients and establish a clinical prediction model. 828 UC patients were included in this retrospective study. 602 patients were in discovery cohort and 226 patients were in validation cohort (internal validation cohort/external validation cohort: 120/106). Clinical and endoscopic data were collected. The discovery cohort was divided into UC group and UCAN group for univariate and multivariate binary logistic analyses. The UCAN clinical prediction model was established and verified. In the univariate analysis, 7 risk factors were related to UCAN. Multivariate logistic regression analysis showed that age at diagnosis of UC (OR: 1.018, 95% CI: 1.003-1.033), Ulcerative Colitis Endoscopic Index of Severity (UCEIS) score (OR: 1.823, 95% CI: 1.562-2.128), and size of polyps (size1: OR: 6.297, 95% CI: 3.669-10.809; size2: OR: 12.014, 95% CI: 6.327-22.814) were independent risk factors of UCAN. A mathematical equation was established. The area under the ROC curve (AUC) of this model was calculated to be 0.845 (95%CI: 0.809-0.881). The sensitivity was 0.884 and the specificity was 0.688. The AUC of internal validation cohort was 0.901 (95%CI: 0.815, 0.988), sensitivity was 75.0% and specificity was 92.6%. The AUC of external validation cohort was 0.842 (95%CI: 0.709, 0.976), sensitivity was 62.5% and specificity was 93.9%. This prediction model is simple, practical, and effective for predicting the risk of UCAN, which is beneficial to the individualized management of patients with UC.

Long-term Risk of Stroke in Patients With Inflammatory Bowel Disease: A Population-Based, Sibling-Controlled Cohort Study, 1969-2019

BACKGROUND AND OBJECTIVES

Patients with inflammatory bowel disease (IBD) are at an increased risk of thromboembolic events, but evidence on the long-term risk of stroke remains scarce. We aimed to explore whether patients with a biopsy-confirmed IBD had an increased long-term risk of stroke.

METHODS

This cohort included all patients with biopsy-confirmed IBD in Sweden between 1969 and 2019 and up to 5 matched reference individuals per patient who were randomly selected from the general population and IBD-free full siblings. The primary outcome was incident overall stroke; secondary outcomes were ischemic and hemorrhagic strokes. Stroke was identified from the Swedish National Patient Register by using both primary and secondary diagnoses. Adjusted hazard ratios (aHRs) for stroke were estimated by flexible parametric survival models.

RESULTS

A total of 85,006 patients with IBD (including Crohn disease [CD, n = 25,257], ulcerative colitis [UC, n = 47,354], and IBD-unclassified [IBD-U, n = 12,395]), 406,987 matched reference individuals, and 101,082 IBD-free full siblings were included in the analysis. We observed 3,720 incident strokes in patients with IBD (incidence rate [IR] 32.6 per 10,000 person-years) and 15,599 in reference individuals (IR 27.7; aHR 1.13, 95% CI 1.08-1.17). The elevated aHR remained increased even 25 years after diagnosis, corresponding to 1 additional stroke case per 93 patients with IBD until then. The excess aHR was mainly driven by ischemic stroke (aHR 1.14; 1.09-1.18) rather than hemorrhagic stroke (aHR 1.06; 0.97-1.15). The risk of ischemic stroke was significantly increased across IBD subtypes (CD [IR 23.3 vs 19.2; aHR 1.19; 1.10-1.29], UC [IR 25.7 vs 22.6; aHR 1.09; 1.04-1.16], and IBD-U [IR 30.5 vs 22.8; aHR 1.22; 1.08-1.37]). Similar results were found when patients with IBD were compared with their siblings.

DISCUSSION

Patients with IBD were at an increased risk of stroke, especially of ischemic events, irrespective of the IBD subtype. The excess risk persisted even 25 years after diagnosis. These findings highlight the need for clinical vigilance about the long-term excess risk of cerebrovascular events in patients with IBD.

Outcomes of bariatric surgery for patients with prevalent inflammatory bowel disease: A nationwide registry-based cohort study

BACKGROUND

Obesity is becoming more prevalent in patients with inflammatory bowel disease. Although bariatric surgery is an effective treatment for obesity, questions remain regarding its safety and effectiveness for patients with inflammatory bowel disease. The aim of this study was to evaluate the safety and effectiveness of bariatric surgery in patients with inflammatory bowel disease.

METHOD

This registry-based, propensity-matched cohort study included all patients who had primary Roux-en-Y gastric bypass or sleeve gastrectomy in Sweden from January 2007 to June 2020 who had an inflammatory bowel disease diagnosis and matched control patients without an inflammatory bowel disease diagnosis. The study included data from the Scandinavian Obesity Surgery Registry, the National Patient Register, the Swedish Prescribed Drugs Register, the Total Population Register, and the Education Register from Statistics Sweden.

RESULTS

In total, 71,093 patients who underwent bariatric surgery, including 194 with Crohn's disease and 306 with ulcerative colitis, were 1:5 matched to non-inflammatory bowel disease control patients. The patients with Crohn's disease had a higher readmission rate within 30 days (10.7% vs 6.1%, odds ratio = 1.84, 95% confidence interval 1.02-3.31) than the control patients, with no significant difference between the surgical methods. The patients with ulcerative colitis had a higher risk for serious postoperative complications after Roux-en-Y gastric bypass (8.0% vs 3.7%, odds ratio = 2.64, 95% confidence interval 1.15-6.05) but not after sleeve gastrectomy compared to control patients (0.8% vs 2.3%). No difference was observed in postoperative weight loss or postoperative health-related quality of life.

CONCLUSION

Sleeve gastrectomy appears to be a safe and effective treatment for obesity in patients with inflammatory bowel disease, whereas Roux-en-Y gastric bypass was associated with a higher risk for postoperative complications in patients with ulcerative colitis.

Management of inflammatory bowel disease in the elderly: A review

The burden of Inflammatory Bowel Disease (IBD) is increasing worldwide, with a particular increase in the prevalence in the elderly population, due to the ageing of young-onset IBD as well as to the increasing incidence in elderly patients. Elderly IBD patients present specific challenges to the treating physician, as they have comorbidities, lower functional reserves, and higher risk of treatment-related complications. The diagnosis of IBD in the elderly may be difficult due to a more subtle disease presentation and to a wide range of differential diagnosis. Moreover, as these patients are often excluded from clinical trials, there is a lack of high-quality evidence to inform on the most appropriate management. Despite an increasing prevalence, the management of IBD in the elderly is still hindered by frequent misconceptions by physicians treating these patients. Due to a erroneous notion of a milder disease course and fear of adverse events, elderly IBD-patients are managed with frequent and continuous use of steroids and undertreated with effective medical therapies. In this review, we describe the principles of management of IBD in the elderly, which is a topic of increasing importance to IBD clinics, that will have to progressively adapt to care for an ageing population.

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.

Patients with elderly onset inflammatory bowel disease have a decreased chance of initiation of all types of medications and increased risk of surgeries-A nationwide cohort study

OBJECTIVE

In patients with elderly (≥60 years) onset inflammatory bowel disease (IBD), we studied initiation of medications, drug persistency and surgeries.

DESIGN

A nationwide cohort study based on Danish registries, comprising incident IBD patients ≥18 years from 1995 to 2020 (N = 69,039). Patients were divided into elderly (N = 19,187) and adult onset (N = 49,852). Outcomes were initiation of thiopurines, 5-ASA, biologics and corticosteroids within 1 and 5 years after diagnosis, and for those who initiated medications, we estimated drug persistency. Surgeries were examined within 1 and 5 years. We used regression models controlling for covariates.

RESULTS

In elderly patients, the adjusted hazard ratios (aHR) for initiating thiopurines, 5-ASA and biologics within 1 year were 0.44 (95% CI 0.42-0.47), 0.77 (95% CI 0.75-0.79) and 0.29 (95% CI 0.26-0.31) respectively. The results were similar within 5 years. In elderly patients, drug persistency for thiopurines, 5-ASA and biologics was not impaired within 5 years. The aHR of stopping steroids within 1 and 5 years were 0.80 (95% CI 0.76-0.84) and 0.77 (95% CI 0.74-0.80) respectively. The risk of surgeries was increased in the elderly patients (in ulcerative colitis, within 5 years, aHR 1.39 [95% CI 1.27-1.52], and in Crohn's disease 1.13 [95% CI 1.04-1.23]).

CONCLUSION

We found significantly low chance of initiation of IBD medications in elderly patients, the reason may not be due to mild disease course. In elderly patients, drug persistency was comparable to adults. Clinicians should carefully consider whether they underuse IBD-specific medications in elderly patients, and special attention should be applied to timely discontinuation of corticosteroids.

Use of real-world data to assess the effectiveness of ustekinumab in treating IBD patients: a retrospective linked database study in northwest London

BACKGROUND

Data on the optimum positioning of biologics in the treatment of inflammatory bowel disease (IBD) are limited.

RESEARCH DESIGN AND METHODS

This was a longitudinal retrospective study of linked health-care data from northwest London, UK, for adults who started ustekinumab for IBD from 1 April 20161 April 2016 to 1 April 20211 April 2021. We compared outcomes by line of therapy (1 vs. 2 or 3+) and age group (18‒59 years or ≥ 60 years). In an analysis of CD patients, we calculated risks of IBD-related hospitalization, IBD-related abdominal surgery, ustekinumab persistence, and switching by line of therapy.

RESULTS

Of 163 patients screened, 149 were eligible. Age had no effect on outcomes. Elective all-cause hospital admissions were significantly higher when ustekinumab was used as second-line or third-line therapy compared with first-line treatment (p = 0.0048 and p = 0.001, respectively). In CD patients the numbers of hospital admissions were also higher with second-line or third-line therapy (p = 0.040 and p = 0.018, respectively). Use of ustekinumab as third-line therapy significantly increased the risk of IBD-related hospitalization (hazard ratio 2.5, 95% CI 1.1‒5.6, p = 0.029), IBD-related abdominal surgery (9.45, 1.2‒75.7, p = 0.03), and switching (14.6, 1.6‒131.0, p = 0.02). Drug persistence risks did not differ.

CONCLUSIONS

These findings support the use of ustekinumab as first-line therapy.

Epidemiology, validation, and clinical characteristics of inflammatory bowel disease: the ABIS birth cohort study

BACKGROUND

Birth cohort studies with linked register-based data on inflammatory bowel disease (IBD) provide opportunities to prospectively study early-life determinants of the disease. However, register-based data often lack information on clinical characteristics and rely on diagnostic algorithms. Within the All Babies in Southeast Sweden (ABIS) cohort, we examined the validity of a register-based definition of IBD, its incidence, and clinical and therapeutic characteristics at diagnosis.

METHODS

We followed 16,223 children from birth (1997-1999) until the end of 2020 for the diagnosis of IBD as defined by a minimum of two diagnostic codes for IBD in the Swedish National Patient Register (NPR). We described the incidence and cumulative incidence of IBD. Through a medical record review of cases diagnosed by the end of 2017, we examined the positive predictive value (PPV) for IBD and described its clinical characteristics and treatment.

RESULTS

By 2020, at an average age of 22.2 years, 113 participants (0.74%, 95% confidence interval [CI] = 0.61-0.89) had a register-based diagnosis of IBD, corresponding to an incidence of 31.3 per 100,000 person-years of follow-up; the incidence for Crohn's disease (CD) was 11.1 per 100,000 person-years and 15.8 for ulcerative colitis (UC). Of 77 participants with a register-based definition of IBD by the end of 2017, medical records were identified for 61 participants, of whom 57 had true IBD (PPV = 93%; 95%CI = 0.87-1.00). While oral 5-aminosalicylic acid treatment was equally common in newly diagnosed CD and UC patients, biologics were more often used for newly diagnosed CD. The median faecal calprotectin levels were 1206 mg/kg at diagnosis and 93 mg/kg at the last follow-up (P < 0.001).

CONCLUSIONS

In this population-based sample of Swedish children and young adults the cumulative IBD incidence was 0.74. The validity of register-based definition of IBD was high and supports using such data to identify IBD patients in cohort studies.
