Advanced age is an independent risk factor for severe infections and mortality in patients given anti-tumor necrosis factor therapy for inflammatory bowel disease

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.

Clinical practice and outcome of patients with elderly-onset ulcerative colitis: Insights from a nationwide claims database study in Japan

Background and Aim

The number of older patients with ulcerative colitis is increasing; however, limited data exist regarding the differences between elderly- and non-elderly-onset ulcerative colitis. We aimed to compare the clinical practice and course of elderly-onset ulcerative colitis with those of non-elderly-onset ulcerative colitis.

Methods

We selected older patients with ulcerative colitis and divided them into the elderly- and non-elderly-onset ulcerative colitis groups according to their age at onset. We compared the cumulative systemic steroid-free, molecular targeting drug-free, and surgery-free rates between the two groups. We performed a multivariate analysis to identify the clinical factors related to systemic steroid administration, the use of molecular targeting drugs, surgery, and death.

Results

We collected data of 2669 and 277 elderly and non-elderly-onset ulcerative colitis patients, respectively. The cumulative systemic steroid-free rate of elderly-onset ulcerative colitis was significantly lower than that of non-elderly-onset ulcerative colitis. However, no difference was observed in the cumulative molecular targeting drugs and surgery-free rates between the two groups. Elderly-onset ulcerative colitis significantly increased the risk of systemic steroid administration and death but not the use of molecular targeting drugs and surgery.

Conclusion

The disease severity of ulcerative colitis and clinical practice may not differ between the elderly- and non-elderly-onset groups. However, elderly-onset ulcerative colitis was associated with increased mortality risk. Thus, we need to pay attention to the patients' condition and appropriate timing of surgery for patients with elderly-onset ulcerative colitis.

Intervention with fructooligosaccharides, Saccharomyces boulardii, and their combination in a colitis mouse model

Objective

To examine the effects of an intervention with fructooligosaccharides (FOS), Saccharomyces boulardii, and their combination in a mouse model of colitis and to explore the mechanisms underlying these effects.

Methods

The effects of FOS, S. boulardii, and their combination were evaluated in a DSS-induced mouse model of colitis. To this end, parameters such as body weight, the disease activity index (DAI), and colon length were examined in model mice. Subsequently, ELISA was employed to detect the serum levels of proinflammatory cytokines. Histopathological analysis was performed to estimate the progression of inflammation in the colon. Gas chromatography was used to determine the content of short-chain fatty acids (SCFAs) in the feces of model mice. Finally, 16S rRNA sequencing technology was used to analyze the gut microbiota composition.

Results

FOS was slight effective in treating colitis and colitis-induced intestinal dysbiosis in mice. Meanwhile, S. boulardii could significantly reduced the DAI, inhibited the production of IL-1β, and prevented colon shortening. Nevertheless, S. boulardii treatment alone failed to effectively regulate the gut microbiota. In contrast, the combined administration of FOS/S. boulardii resulted in better anti-inflammatory effects and enabled microbiota regulation. The FOS/S. boulardii combination (109 CFU/ml and 107 CFU/ml) significantly reduced the DAI, inhibited colitis, lowered IL-1β and TNF-α production, and significantly improved the levels of butyric acid and isobutyric acid. However, FOS/S. boulardii 109 CFU/ml exerted stronger anti-inflammatory effects, inhibited IL-6 production and attenuated colon shortening. Meanwhile, FOS/S. boulardii 107 CFU/ml improved microbial regulation and alleviated the colitis-induced decrease in microbial diversity. The combination of FOS and S. boulardii significantly increased the abundance of Parabacteroides and decreased the abundance of Escherichia-Shigella. Additionally, it promoted the production of acetic acid and propionic acid.

Conclusion

Compared with single administration, the combination can significantly increase the abundance of beneficial bacteria such as lactobacilli and Bifidobacteria and effectively regulate the gut microbiota composition. These results provide a scientific rationale for the prevention and treatment of colitis using a FOS/S. boulardii combination. They also offer a theoretical basis for the development of nutraceutical preparations containing FOS and S. boulardii.

Inflammatory Bowel Diseases in the Elderly: A Focus on Disease Characteristics and Biological Therapy Patterns

Background: The incidence of inflammatory bowel diseases (IBDs) in elderly patients is constantly increasing. It results from the combination of an aging population with compounding prevalence of IBD, as well as the growing burden of elderly-onset IBD. The clinical characteristics of elderly patients differ from young subjects with IBD due to the multimorbidity or polypharmacy, affecting the choice of adequate therapeutic options. The aim of this study was to determine the clinical aspects and biological therapy safety in elderly Polish IBD patients. Methods: We conducted a retrospective study aimed at describing the demographic, clinical, and management characteristics of IBD patients treated with a biological therapy in two referral centers within the National Drug Program in Poland. Results: Out of the entire group of 366 studied patients, 51 (13.9%) were aged over 60-32 with ulcerative colitis (UC) and 19 with Crohn's disease (CD). The disease location was predominantly ileocolonic (57.89%) in patients with CD and pancolitis for patients with UC (56.25%). Most of the elderly IBD subjects were characterized by significant comorbidities, with Charlson Comorbidity Index (CCI) ≥ 1 in 66.67% patients. The probability of stopping biological therapy due to adverse events had the tendency to be higher in the CCI ≥ 1 group (20.58% vs. 5.88% in CCI = 0; p = 0.087). The main reasons for the therapy discontinuation included hypersensitivity reactions and liver enzyme abnormalities. Conclusions: In conclusion, our results underline the importance of assessing the comorbidity status instead of the age prior to initiating biological therapy, analyzing additional safety risks, and close monitoring in IBD patients with multiple comorbidities.

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.

Safety and Effectiveness of Vedolizumab in Elderly Patients with Inflammatory Bowel Disease: A Systematic Review & Meta-Analysis

BACKGROUND

There is limited data on Vedolizumab utilization in elderly patients. Our study aims to assess the effectiveness and safety of Vedolizumab in this subset population.

MATERIALS AND METHODS

Databases including Cochrane Central, Embase, Medline (via Ovid), Scopus, and Web of Science were searched in August 2022 to identify studies that assessed Vedolizumab therapy in elderly patients. Pooled proportion and risk ratios (RR) were calculated.

RESULTS

Total 11 studies with 3546 IBD patients (1314 elderly and 2232 young) were included in the final analysis. Pooled rate of overall and serious infections in the elderly cohort was 8.45% (95% CI=6.27-11.29; I 2 23%) and 2.59% (95% CI=0.78-8.29; I 2 76%), respectively. However, there was no difference in overall infection rates between elderly and young patients. Pooled rate of endoscopic, clinical, and steroid-free remission for elderly IBD patients was 38.45% (95% CI=20.74-59.56; I 2 93%), 37.95% (95% CI=33.08-43.06; I 2 13%), and 38.8% (95% CI=31.6-46.4; I 2 77%), respectively. Elderly patients had lower steroid-free remission rates [RR 0.85, 95% CI=0.74-0.99; I 2 0%, P =0.03]; however, there was no difference in rates of clinical (RR 0.86, 95% CI=0.72-1.03; I 2 0%, P =0.10) or endoscopic remission (RR 1.06, 95% CI=0.83-1.35; I 2 0%, P =0.63) compared with younger patients. Pooled rate of IBD-related surgery and IBD-related hospitalizations was 9.76% (95% CI=5.81-15.92; I 2 78%) and 10.54% (95% CI=8.37-13.2; I 2 0%), respectively for the elderly cohort. There was no statistical difference in IBD-related surgeries between elderly and young IBD patients, RR 1.20 (95% CI=0.79-1.84; I 2 16%), P =0.4.

CONCLUSIONS

Vedolizumab is equally safe and effective for clinical and endoscopic remission in elderly and younger populations.

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.

Safety and potential interaction of immunosuppressive drugs for the treatment of inflammatory bowel disease in elderly patients

Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, are chronic diseases associated with increased morbidity and reduced quality of life. Age may represent a risk factor for adverse events, due to the multimorbidity and polypharmacy, common in elderly patients. Elderly are often not included in clinical trials evaluating efficacy and safety of study drugs for the treatment of inflammatory bowel diseases. Several drugs, such as aminosalicylates, systemic corticosteroids, immunosuppressant drugs, biological drugs and Janus Kinase inhibitors, are available for the management of inflammatory bowel diseases. Therefore, with the increasing spectrum of therapeutic options it is important to analyze the evidence regarding the safety of the use of these agents in elderly patients. Selection of immunosuppressive therapy is a challenge in the management of elderly patients with inflammatory bowel diseases, for whom biologics with a lower risk of infection or cancer, such as vedolizumab and ustekinumab, may be preferred in elderly patients. Concomitant therapies and comorbidities must be thoroughly investigated before initiating any immunosuppressive or biological therapy in order to minimize the risk of drug-drug interactions. This review aimed to provide an overview of the safety of thiopurines, methotrexate and target therapies as well as their drug-drug interactions in patients with inflammatory bowel diseases.

Immune system and gut microbiota senescence in elderly IBD patients

In inflammatory bowel disease (IBD), the loss of immune tolerance against gut microbiota causes chronic inflammation and the progressive accumulation of organ damage in genetically susceptible individuals. In the elderly, IBD is often characterized by a different disease behavior when compared with pediatric and young adult disease. Besides disease behavior, another aspect of the multifaceted impact of age on elderly IBD course is increased susceptibility to infections. In this context, age-of-onset-dependent IBD behavior and clinical course are two major contributors to immune system senescence and change of gut microbiota in older subjects. Here, we review the available literature linking immunosenescence and age-dependent changes in the gut microbiota composition to IBD pathogenesis speculating on their possible implications in disease expression in this age class.

Safety and Effectiveness of Vedolizumab and Ustekinumab in Elderly Patients with Inflammatory Bowel Disease: A Real-Life Multicentric Cohort Study

BACKGROUND

Data on ustekinumab and vedolizumab in the elderly inflammatory bowel disease (IBD) population are limited. The aim of the current study was to assess the safety and effectiveness of both in an elderly real-life population.

METHODS

A multicentric retrospective study was performed on IBD patients who started vedolizumab or ustekinumab between 2010 and 2020. Clinical and endoscopic remission rates and (serious) adverse events (AE) were assessed.

RESULTS

A total of 911 IBD patients were included, with 171 (19%) aged above 60 (111 VDZ, 60 UST). Elderly patients treated with vedolizumab or ustekinumab had an increased risk for non-IBD hospitalization (10.5% vs. 5.7%, p = 0.021) and malignancy (2.3% vs. 0.5%, p = 0.045) compared to the younger population. Corticosteroid-free clinical (50% vs. 44%; p = 0.201) and endoscopic remission rates (47.9% vs. 31%, p = 0.07) at 1 year were similar. Comparing vedolizumab to ustekinumab in the elderly population, corticosteroid-free (47.9% vs. 31%, p = 0.061) and endoscopic remission rates (66.7% vs. 64.4%, p = 0.981) were similar. Vedolizumab- and ustekinumab-treated patients had comparable infection rates (13.5% vs. 10.0%, p = 0.504), IBD flare-ups (4.5% vs. 5%, p = 1.000), the occurrence of new EIMs (13.5% vs. 10%, p = 0.504), a risk of intestinal surgery (5.4% vs. 6.7%, p = 0.742), malignancy (1.8% vs. 3.3%, p = 0.613), hospitalization (9.9% vs. 11.7%, p = 0.721), and mortality (0.9% vs. 1.7%, p = 1.000). AE risk was associated only with corticosteroid use.

CONCLUSIONS

Ustekinumab and vedolizumab show comparable effectiveness and safety in the elderly IBD population. Elderly IBD patients have an increased risk for non-IBD hospitalizations and malignancy compared to the younger IBD population, with corticosteroid use as the main risk factor.

Efficacy and safety of tacrolimus in older adults with ulcerative colitis: a retrospective study

BACKGROUND/AIMS

The prevalence of ulcerative colitis (UC) has been increasing, also in older adults. Here, we retrospectively compared the efficacy and safety of tacrolimus (TAC) in older and younger patients with UC.

METHODS

We included younger (age < 65 years; n = 116) and older patients (age ≥ 65 years; n = 21) with UC who received TAC from April 2009 through December 2022(mean follow-up, 1230 ± 175 days) and achieved remission. Evaluations included age at onset, laboratory values, estimated glomerular filtration rate (eGFR), use of 5-aminosalicylic acid (5-ASA), biological experience, colonoscopy scores, remission at 1 month after treatment initiation, and adverse events. Treatment duration and renal function were assessed in patients with follow-up data (younger patients, n = 110; older patients, n = 19).

RESULTS

Older patients had a higher age at onset and treatment initiation but less 5-ASA use and biological experience. Before treatment, hemoglobin, albumin, and eGFR were significantly lower in the older group and CRP was significantly higher. The remission rate was 80.1% in the younger group and 66.6% in the older group (P = 0.1862). Adverse events were similar in both groups. The older group had a shorter treatment duration and significantly less change in renal function at all time points.

DISCUSSION

Rates of TAC-induced remission and adverse events were similar in older and younger adults with UC.

CONCLUSION

TAC can be used safely in elderly patients with moderate to severe UC with careful monitoring.

Prevalence and risk factors for early medical and surgical complications following an admission for acute severe ulcerative colitis

Background

Risk factors for colectomy following an episode of acute severe ulcerative colitis (ASUC) have been well studied, but data examining the early complications following an episode is limited.

Objectives

We aimed to evaluate the prevalence and risk factors for medical and surgical complications within 90 days of an ASUC admission and determine if a high-intensity induction infliximab dose is associated with these complications.

Design

Retrospective analysis.

Methods

We conducted a retrospective study of ASUC admissions between January 2015 and July 2021 at a tertiary hospital. The primary outcome was the prevalence of total, medical and surgical complications within 90 days following an ASUC admission. Multivariate linear regression analysis assessed for factors associated with the prevalence of complications.

Results

A total of 150 patients had 186 hospital admissions for ASUC. In total, 101/186 (54.3%) admissions required rescue medical therapy. Standard infliximab induction occurred in 65/100 admissions, accelerated infliximab induction in 35/100 and cyclosporine in 1/100 of admissions. In total, 117 complications, including 74/117 (63.2%) medical and 43/117 (36.8%) surgical complications, arose. Low serum albumin was independently associated with a higher incidence of total [β = -0.08 (95% confidence interval (CI): -0.15, -0.01), p = 0.03] and surgical complications [β = -0.1 (95% CI: -0.18, -0.001), p = 0.047], while an increased age was associated with increased incidence of surgical complications [β = 0.06 (95% CI: 0.01, 0.12), p = 0.02]. A higher Charlson score was associated with increased medical complications [β = 0.12 (95% CI: 0.01, 0.24), p = 0.03]. Infliximab induction dose intensity was not associated with an increased incidence of any complications.

Conclusion

Early complications following an ASUC admission is prevalent although the majority are not serious. Risk factors associated with complications include low serum albumin, older age and a higher comorbidity score. Induction infliximab dose intensity, however, is not a risk factor.

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.

Long-term prognosis and clinical practice for new-onset ulcerative colitis in the era of biologics: A Japanese retrospective study

Background and Aim

There is a scarcity of data on long-term outcomes in patients with new-onset ulcerative colitis (UC) in the era of biologics. We aimed to clarify the long-term prognosis of UC and the clinical practice of prescriptions for UC.

Methods

We collected 6689 new-onset UC cases using a medical claim database provided by DeSC Healthcare, Inc. We investigated the surgery-free, systemic steroid-free, and molecular targeting drug-free rates and compared their differences based on UC-onset age. We used multivariate analysis to identify clinical factors affecting long-term prognosis and investigated the transition of prescriptions for UC.

Results

The surgery-free, systemic steroid-free, and molecular targeting drug-free rates at 5 years post-UC diagnosis were 98.5%, 61.0%, and 88.7%, respectively. Pediatric patients had higher surgery-free rates compared with elderly patients and non-pediatric/non-elderly patients (P = 0.022), whereas the systemic steroid-free and molecular targeting drug-free rates were significantly lower (P< 0.0001, P < 0.0001, respectively). The retention rate of the first molecular targeting drug did not differ between drugs. The prescription rates of systemic steroid, immunomodulator, and molecular targeting drug increased from the second quarter in 2014 to the fourth quarter in 2021 (29.8%-39.1%, 6.8%-17.7%, and 7.6%-16.4%, respectively).

Conclusions

We clarified the long-term prognosis and clinical practice of new-onset UC cases. The long-term outcome after UC onset might improve because of increasing use of new therapeutic agents. Further investigations are warranted.

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.

Extraintestinal Cancers in Inflammatory Bowel Disease: A Literature Review

BACKGROUND

Inflammatory bowel disease (IBD) is a group of chronic multifactorial inflammatory disorders including two major entities: Crohn's disease (CD) and ulcerative colitis (UC). Preliminary evidence suggests that patients with IBD may be at increased risk of developing intestinal and extraintestinal cancers (EICs). Actually, little is known about the association between IBD and EICs, and there is ever-growing concern regarding the safety of immunomodulators and biological therapy, which may represent a risk factor for carcinogenesis.

AIMS

The aim of this review is to summarize the evidence regarding the association between IBD and EICs, the safety of immunomodulators and biological therapy and the management of immunomodulators and biologic agents in IBD patients with prior or current EICs.

RESULTS

IBD patients have a higher risk of developing different forms of extraintestinal solid organ tumors and hematological malignancies. Immunomodulators and biological therapy may increase the risk of developing some types of EICs and may be consciously used in patients with IBD and current or prior history of malignancy.

CONCLUSIONS

Decisions regarding the use of immunomodulators or biological therapies should be made on an individual basis, considering a multidisciplinary approach involving oncologists.

Glycosides as Potential Medicinal Components for Ulcerative Colitis: A Review

Ulcerative colitis (UC) is a chronic, non-specific disease of unknown etiology. The disease develops mainly in the rectum or colon, and the main clinical symptoms include abdominal pain, diarrhea, and purulent bloody stools, with a wide variation in severity. The specific causative factors and pathogenesis of the disease are not yet clear, but most scholars believe that the disease is caused by the interaction of genetic, environmental, infectious, immune, and intestinal flora factors. As for the treatment of UC, medications are commonly used in clinical practice, mainly including aminosalicylates, glucocorticoids, and immunosuppressive drugs. However, due to the many complications associated with conventional drug therapy and the tendency for UC to recur, there is an urgent need to discover new, safer, and more effective drugs. Natural compounds with biodiversity and chemical structure diversity from medicinal plants are the most reliable source for the development of new drug precursors. Evidence suggests that glycosides may reduce the development and progression of UC by modulating anti-inflammatory responses, inhibiting oxidative stress, suppressing abnormal immune responses, and regulating signal transduction. In this manuscript, we provide a review of the epidemiology of UC and the available drugs for disease prevention and treatment. In addition, we demonstrate the protective or therapeutic role of glycosides in UC and describe the possible mechanisms of action to provide a theoretical basis for preclinical studies in drug development.

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.

Efficacy and Safety of Biological Therapies and JAK Inhibitors in Older Patients with Inflammatory Bowel Disease

With the introduction of more and more monoclonal antibodies selectively targeting various mediators of the immune system, together with Janus-Kinase (JAK)-inhibitors with variable affinities towards different JAK subtypes, the available therapeutic options for the treatment of inflammatory bowel diseases (IBD) have undergone an acceleration in the last five years. On the other hand, the prevalence of IBD patients over 65-years-old is steadily increasing, and, with this, there is a large population of patients that presents more comorbidities, polypharmacy, and, more frequently, frailty compared to younger patients, exposing them to potentially major risks for adverse events deriving from newer therapies, e.g., infections, cardiovascular risks, and malignancies. Unfortunately, pivotal trials for the commercialization of new therapies rarely include older IBD patients, and those with serious comorbidities are virtually excluded. In the present review, we focus on existing literature from pivotal trials and real-world studies, analyzing data on efficacy/effectiveness and safety of newer therapies in older IBD patients with special emphasis on comorbidities and frailty, two distinct but intercorrelated aspects of the older population since age by itself seems to be of minor importance.

Recent advances in the treatment of IBD: Targets, mechanisms and related therapies

Inflammatory bowel disease (IBD), as a representative inflammatory disease, currently has multiple effective treatment options available and new therapeutic strategies are being actively explored to further increase the treatment options for patients with IBD. Furthermore, biologic agents and small molecule drugs developed for ulcerative colitis (UC) and Crohn's disease (CD) have evolved toward fewer side effects and more accurate targeting. Novel inhibitors that target cytokines (such as IL-12/23 inhibitors, PDE4 inhibitors), integrins (such as integrin inhibitors), cytokine signaling pathways (such as JAK inhibitors, SMAD7 blocker) and cell signaling receptors (such as S1P receptor modulator) have become the preferred treatment choice for many IBD patients. Conventional therapies such as 5-aminosalicylic acid, corticosteroids, immunomodulators and anti-tumor necrosis factor agents continue to demonstrate therapeutic efficacy, particularly in combination with drug therapy. This review integrates research from chemical, biological and adjuvant therapies to evaluate current and future IBD therapies, highlighting the mechanism of action of each therapy and emphasizing the potential of development prospects.

Older adults with acute severe ulcerative colitis have similar steroid non-response and colectomy rates as younger adults

BACKGROUND

There is paucity of data on outcomes of acute severe ulcerative colitis (ASUC) in older adults (≥ 60 years of age).

AIM

To assess steroid non-response rates during the index admission for ASUC in older adults. Secondary outcomes were response to medical rescue therapy and colectomy rates; at index admission, 3 and 12 mo.

METHODS

This retrospective multicentre cohort study included ASUC admissions who received intravenous steroids between January 2013 and July 2020 at two tertiary hospitals. Electronic medical records were reviewed to collect clinical, biochemical, and endoscopic data. A modified Poisson regression model was used for analysis.

RESULTS

Of 226 ASUC episodes, 45 (19.9%) occurred in patients ≥ 60 years of age. Steroid non-response rates were comparable in older adults and patients < 60 years of age [19 (42.2%) vs 85 (47%), P = 0.618, crude risk ratio (RR) = 0.89 [95% confidence interval (CI): 0.61-1.30], adjusted RR = 0.99 (0.44-2.21). Rates of response to medical rescue therapy in older adults was comparable to the younger cohort [76.5% vs 85.7%, P = 0.46, crude RR = 0.89 (0.67-1.17)]. Index admission colectomy [13.3% vs 10.5%, P = 0.598, crude RR = 1.27 (0.53-2.99), adjusted RR = 1.43 (0.34-6.06)], colectomy at 3 mo [20% vs 16.6%, P = 0.66, crude RR = 1.18 (0.61-2.3), adjusted RR = 1.31 (0.32-0.53)] and colectomy at 12 mo [20% vs 23.2%, P = 0.682, crude RR = 0.85 (0.45-1.57), adjusted RR = 1.21 (0.29-4.97)], were similar between the two groups.

CONCLUSION

In older adults with ASUC, the steroid non-response rate, response to medical rescue therapy, and colectomy rate at index admission, 3 and 12 mo is similar to patients less than 60 years of age.

Insights into Mesalazine Use in Clinical Practice of Young Gastroenterologists

BACKGROUND

Mesalazine is among the medications most prescribed by gastroenterologists, with variable and controversial use in different settings. We aimed to explore the use of mesalazine in the clinical practice of young gastroenterologists.

METHODS

A web-based electronic survey was distributed to all participants of the National Meeting of the Italian Young Gastroenterologist and Endoscopist Association.

RESULTS

A total of 101 participants took part in the survey, with a majority (54.4%) being aged >30 years, 63.4% of whom were trainees in academic hospitals, and 69.3% of whom were involved in the clinical management of inflammatory bowel disease (IBD). While both non-dedicated and IBD physicians generally agreed on the appropriate dose of mesalazine for mild ulcerative colitis (UC), significant differences were observed between the two groups for moderate-severe ulcerative colitis (UC). Additionally, in IBD patients who were starting immuno-modulators and/or biologics, 80% of IBD-dedicated physicians continued to prescribe mesalazine, compared to 45.2% of non-dedicated physicians (p = 0.002). Indeed, 48.4% of non-dedicated IBD physicians did not acknowledge mesalazine for colorectal cancer chemoprevention. With regards to Crohn's disease, it is mainly used by 30.1% of IBD physicians for preventing postoperative recurrence of Crohn's disease. Finally, 57.4% used mesalazine for symptomatic uncomplicated diverticular disease, and 84.2% did not recommend its use for irritable bowel syndrome.

CONCLUSIONS

This survey showed heterogeneous behaviors in the daily use of mesalazine, mainly in the management of IBD. Educational programs and novel studies are needed to clarify its use.

Expert consensus on vaccination in patients with inflammatory bowel disease in Japan

Immunosuppressive therapies can affect the immune response to or safety of vaccination in patients with inflammatory bowel disease (IBD). The appropriateness of vaccination should be assessed prior to the initiation of IBD treatment because patients with IBD frequently undergo continuous treatment with immunosuppressive drugs. This consensus was developed to support the decision-making process regarding appropriate vaccination for pediatric and adult patients with IBD and physicians by providing critical information according to the published literature and expert consensus about vaccine-preventable diseases (VPDs) [excluding cervical cancer and coronavirus disease 2019 (COVID-19)] in Japan. This consensus includes 19 important clinical questions (CQs) on the following 4 topics: VPDs (6 CQs), live attenuated vaccines (2 CQs), inactivated vaccines (6 CQs), and vaccination for pregnancy, childbirth, and breastfeeding (5 CQs). These topics and CQs were selected under unified consensus by the members of a committee on intractable diseases with support by a Health and Labour Sciences Research Grant. Physicians should provide necessary information on VPDs to their patients with IBD and carefully manage these patients' IBD if various risk factors for the development or worsening of VPDs are present. This consensus will facilitate informed and shared decision-making in daily IBD clinical practice.

Effectiveness and Safety of Ustekinumab in Elderly Patients with Crohn's Disease: Real World Evidence From the ENEIDA Registry

BACKGROUND AND AIMS

Clinical trials and real-life studies with ustekinumab in Crohn's disease [CD] have revealed a good efficacy and safety profile. However, these data are scarcely available in elderly patients. Therefore, we aim to assess the effectiveness and safety of ustekinumab in elderly patients with CD.

METHODS

Elderly patients [>60 years old] from the prospectively maintained ENEIDA registry treated with ustekinumab due to CD were included. Every patient was matched with two controls under 60 years of age, according to anti-tumour necrosis factor use and smoking habit. Values for the Harvey-Bradshaw Index [HBI], endoscopic activity, C-reactive protein [CRP] and faecal calprotectin [FC] were recorded at baseline and at weeks 16, 32 and 54.

RESULTS

In total, 648 patients were included, 212 of whom were elderly. Effectiveness was similar between young and elderly patients during the follow-up. Steroid-free remission was similar at week 16 [54.6 vs 51.4%, p = 0.20], 32 [53.0% vs 54.5%, p = 0.26] and 54 [57.8% vs 51.1%, p = 0.21]. Persistence of ustekinumab as maintenance therapy was similar in both age groups [log-rank test; p = 0.91]. There was no difference in the rate of adverse effects [14.2% vs 11.2%, p = 0.350], including severe infections [7.1% vs 7.3%, p = 1.00], except for the occurrence of de novo neoplasms, which was higher in older patients [0.7% vs 4.3%, p = 0.003].

CONCLUSIONS

Ustekinumab is as effective in elderly patients with CD as it is in non-elderly patients. The safety profile also seems to be similar except for a higher rate of de novo neoplasms, probably related to the age of the elderly patients.

Personalize, participate, predict, and prevent: 4Ps in inflammatory bowel disease

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a complex, immune-mediated, disorder which leads to several gastrointestinal and systemic manifestations determining a poor quality of life, disability, and other negative health outcomes. Our knowledge of this condition has greatly improved over the last few decades, and a comprehensive management should take into account both biological (i.e., disease-related, patient-related) and non-biological (i.e., socioeconomic, cultural, environmental, behavioral) factors which contribute to the disease phenotype. From this point of view, the so called 4P medicine framework, including personalization, prediction, prevention, and participation could be useful for tailoring ad hoc interventions in IBD patients. In this review, we discuss the cutting-edge issues regarding personalization in special settings (i.e., pregnancy, oncology, infectious diseases), patient participation (i.e., how to communicate, disability, tackling stigma and resilience, quality of care), disease prediction (i.e., faecal markers, response to treatments), and prevention (i.e., dysplasia through endoscopy, infections through vaccinations, and post-surgical recurrence). Finally, we provide an outlook discussing the unmet needs for implementing this conceptual framework in clinical practice.

Ileal Pouch-Anal Anastomosis in the Older Adult: a Review of Postoperative Outcomes and Pouchitis Treatment

PURPOSE OF REVIEW

Ileal pouch-anal anastomosis (IPAA) has become the preferred surgical treatment for patients with medically refractive ulcerative colitis (UC). Previous studies have suggested that outcomes of this procedure may be worse in older patients; however, more recent reports have suggested that IPAA in select patients is safe, feasible, and results in good quality of life. In this review, we discuss the recent literature surrounding clinical considerations and treatment management of IPAA in older adults.

RECENT FINDINGS

IPAA complication rates and adverse events are similar in the older adult population, as compared to the younger adult patient population. Although fecal urgency and incontinence may be more common among older adults, chronological age alone is not a contraindication for IPAA surgery, as good quality of life can still be achieved. In this review, we will also discuss the development of pouchitis after IPAA, particularly among older adults, as the emergence of newer biologic drugs has shifted the treatment landscape.

SUMMARY

IPAA can be a safe and effective treatment modality for older adults with UC, with high self-reported patient satisfaction. Patient optimization and careful case selection are vital to achieving these outcomes, and specialized preoperative assessments and counseling can help facilitate the proper treatment.

Ustekinumab and Vedolizumab Are Equally Safe and Effective in Elderly Crohn's Disease Patients

BACKGROUND

Anti-tumour necrosis factor (anti-TNF) agents are associated with increased infection risk among elderly inflammatory bowel disease (IBD) patients, and thus, alternative biologics may be preferable. However, little comparative data exist on the safety and efficacy of vedolizumab and ustekinumab in elderly IBD patients.

AIMS

To compare the safety and effectiveness of ustekinumab and vedolizumab in elderly Crohn's disease patients.

METHODS

Patients ≥ 60 years old who commenced ustekinumab or vedolizumab for Crohn's disease (CD) were included. Primary outcome was serious infections, defined as requiring hospitalisation. Efficacy was assessed by treatment persistence and clinical response rates. We appropriately adjusted for confounders using propensity score-matched analysis weighted by the inverse predicted probability of treatment weighing and performed a logistic regression analysis to assess factors associated with serious infections and treatment persistence.

RESULTS

Eighty-three patients commencing ustekinumab and 42 commencing vedolizumab therapy were included. In a propensity adjusted cohort, the rate of serious infection and treatment persistence were comparable between ustekinumab and vedolizumab. There was a significant reduction in HBI at 6 and 12 months compared to baseline in both groups. Male gender was positively associated with serious infection risk at 12 months, and penetrating disease behaviour was positively associated with 12-month treatment persistence. Baseline HBI score was negatively associated with 12-month treatment persistence. Cox regression analysis showed no overall difference in treatment discontinuation-free and serious infection-free survival by 12 months.

CONCLUSIONS

We observed comparable safety and effectiveness for ustekinumab and vedolizumab in treating elderly CD patients.

Saudi Arabia consensus guidance for the diagnosis and management of adults with inflammatory bowel disease

Optimal management of inflammatory bowel disease (IBD) relies on a clear understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This article provides concise guidelines for the management of IBD in adults, based on the most up-to-date information at the time of writing and will be regularly updated. These guidelines were developed by the Saudi Ministry of Health in collaboration with the Saudi Gastroenterology Association and the Saudi Society of Clinical Pharmacy. After an extensive literature review, 78 evidence-and expert opinion-based recommendations for diagnosing and treating ulcerative colitis and Crohn's disease in adults were proposed and further refined by a voting process. The consensus guidelines include the finally agreed on statements with their level of evidence covering different aspects of IBD diagnosis and treatment.

Assessment of Safety and Efficacy of Tofacitinib, Stratified by Age, in Patients from the Ulcerative Colitis Clinical Program

BACKGROUND

In patients with ulcerative colitis (UC), risks of infection and malignancies increase with age. Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of UC. This analysis assessed age as a risk factor for adverse events of special interest (AESI) in the tofacitinib UC clinical program.

METHODS

Data were from phase 2 and 3 induction studies, a phase 3 maintenance study, and an open-label, long-term extension study. Efficacy and/or safety outcomes were analyzed in the Induction, Maintenance, and Overall Cohorts (patients who received ≥ 1 dose of tofacitinib), stratified by age. The effects of baseline demographic and disease-related factors on AESI incidence were assessed by Cox proportional-hazards regression analysis.

RESULTS

In the Overall Cohort (1157 patients with ≤ 6.8 years' tofacitinib treatment), age was a statistically significant predictor of herpes zoster (HZ), malignancies excluding nonmelanoma skin cancer (NMSC), and NMSC. Other statistically significant predictors included prior tumor necrosis factor inhibitor failure for HZ, NMSC, and opportunistic infection events, and prior duration of UC for malignancies excluding NMSC. In the Induction and Maintenance Cohorts, a higher proportion of tofacitinib-treated than placebo-treated patients (numerical difference) achieved the efficacy endpoints (endoscopic improvement, clinical remission, clinical response) across all age groups.

CONCLUSIONS

Older individuals receiving tofacitinib as induction and maintenance therapy to treat UC may have an increased risk of HZ, malignancies (excluding NMSC), and NMSC versus similarly treated younger patients, consistent with findings from the general population. Across all age groups, tofacitinib demonstrated greater efficacy than placebo as an induction and maintenance therapy.

Safety and effectiveness of ustekinumab in elderly Crohn's disease patients

OBJECTIVE

Anti-tumour necrosis factor (TNF) agents are associated with increased infection risk among elderly IBD patients, but little is known about non anti-TNF biologics in this cohort. We examined the safety and effectiveness of ustekinumab in elderly Crohn's patients.

METHODS

This retrospective multi-centre cohort study included Crohn's patients ≥60-years old who commenced ustekinumab. We recorded Harvey-Bradshaw index (HBI), concomitant steroid therapy, treatment persistence and new infections or malignancies. Primary outcome was serious infections requiring hospitalisation.

RESULTS

Seventy patients were included, with median age of 68 years. 43 (61.4%) had prior anti-TNF exposure, and 15 (21.4%) vedolizumab. Median treatment duration was 12 months, totalling 84 patient-years. Nine serious infections were reported, incidence 106.7/1000 patient-years. Systemic steroids were associated with increased risk of serious infections [odds ratio (OR) 7.83, 95% confidence interval (CI): 1.44-44.32, P = 0.02]. There were 27 "non-serious" infections; 321.4/1000 patient-years. Charlson co-morbidity index (OR 1.49, 95% CI: 1.05-2.12, P = 0.03) and steroid exposure (OR 44.10, 95% CI: 1.75-1112.10, P = 0.02) increased non-serious infection risk (P &lt; 0.05). Mean HBI improved from 8.13 to 4.64 at 6 months and 4.10 at last follow up (P &lt; 0.0001). 12-month treatment persistence was 55.7% (N = 39); 34 (48.6%) were steroid-free.

CONCLUSION

Ustekinumab was safe and effective in a cohort of elderly Crohn's disease patients. Infections were mostly mild, not resulting in therapy discontinuation. Serious infection risk was comparable to previously reported rates with anti-TNF agents. Steroid exposure was associated with an increased serious infection risk.

Safety of Biological Therapies in Elderly Inflammatory Bowel Diseases: A Systematic Review and Meta-Analysis

Background and Aim: Newer biologics appeared safer in landmark clinical trials, but their safety is understudied in vulnerable populations. The aim of the present study was to perform a systematic review and meta-analysis to assess the safety of available biologicals in the elderly IBD population. Methods: We systematically searched PubMed/Medline and conference proceedings between 1 April 1969 and 1 June 2021 to identify eligible studies that examined the safety of biologics in elderly patients with IBD. Of the 2885 articles and 12 congress abstracts identified, 12 peer reviewed papers and 3 abstracts were included after independent evaluation by two reviewers. The identified studies collected safety data on anti-TNF, vedolizumab (VDZ) and ustekinumab (UST). Results: Rates of AE and infections were not different among the biologics (AE mean rate: 11.3 (CI 95% 9.9–12.7)/100 pts-years; p = 0.11, infection mean rate: 9.5 (CI 95% 8.4–10.6)/100 pts-years; p = 0.56) in elderly IBD patients on anti-TNF, VDZ or UST. Infusion/injection reaction rates were more common on anti-TNFs (mean rate: 2.51 (CI 95% 1.7–3.4/100 pts-years; p = 0.02). and malignancy rates were higher on VDZ/UST (mean rate: 2.14 (CI 95% 1.6–2.8)/100 pts-years; p = 0.01). Conclusions: Rates of AEs and infections were not different among biologicals. Infusion/injection reactions were more common on anti-TNFs. Current data are insufficient to suggest the sequencing of biologicals in elderly patients based on safety.

Risk of Immunomediated Adverse Events and Loss of Response to Infliximab in Elderly Patients with Inflammatory Bowel Disease: A Cohort Study of the ENEIDA Registry

BACKGROUND AND AIMS

Immunomediated adverse events [IAEs] are the most frequently reported infliximab [IFX]-related adverse events. Combination therapy may reduce their incidence, although this strategy is not recommended in elderly patients. We aimed to compare the rates of IFX-related IAEs and loss of response [LOR] in elderly and younger patients.

METHODS

Adult patients in the ENEIDA registry who had received a first course of IFX therapy were identified and grouped into two cohorts regarding age at the beginning of treatment [over 60 years and between 18 and 50 years]. The rates of IAEs and LOR were compared.

RESULTS

In total, 939 patients [12%] who started IFX over 60 years of age and 6844 [88%] below 50 years of age were included. Elderly patients presented a higher proportion of AEs related to IFX [23.2% vs 19%; p = 0.002], infections [7.1% vs 4.3%; p < 0.001] and neoplasms [2.2% vs 0.5%; p < 0.001]. In contrast, the rates of IAEs [14.8% vs 14.8%; p = 0.999], infusion reactions [8.1% vs 8.1%; p = 0.989], late hypersensitivity [1.3% vs 1.2%; p = 0.895], paradoxical psoriasis [1% vs 1.5%; p = 0.187] and drug-induced lupus erythematosus [0.6% vs 0.7%; p = 0.947] were similar in elderly and younger patients. LOR rates were also similar between the two groups [20.5% vs 19.3%; p = 0.438]. In the logistic regression analysis, IFX monotherapy, extraintestinal manifestations and female gender were the only risk factors for IAEs, whereas IFX monotherapy, extraintestinal manifestations and Crohn's disease were risk factors for LOR.

CONCLUSIONS

Elderly patients with inflammatory bowel disease have a similar risk of developing IFX-related IAEs and LOR to that of younger patients.

Older Adult Patients Use More Aminosalicylate Monotherapy Compared With Younger Patients With Inflammatory Bowel Disease: TARGET-IBD

GOAL

The goal of this study was to describe medication utilization patterns in older inflammatory bowel disease (IBD) patients.

BACKGROUND

Despite a growing population of older patients with Crohn's disease (CD) and ulcerative colitis (UC), questions remain regarding medication utilization patterns in comparison to younger populations.

MATERIALS AND METHODS

We collected data from the 34 sites in TARGET-IBD, a multicenter, observational cohort. The primary outcome in this study was the IBD-specific therapy utilized among older patients with IBD compared with younger age groups. Therapy use was analyzed using pairwise comparisons and then the odds of IBD-specific therapy use among patients older than age 65 were evaluated using multivariable logistic regression models.

RESULTS

We identified 2980 patients with IBD (61% CD). In multivariable analysis, younger patients with UC were significantly less likely to utilize aminosalicylate monotherapy when compared with patients above 65 years [age 18 to 29: adjusted odds ratio (aOR)=0.51, 95% confidence interval (CI): 0.33-0.78]. In patients with CD, younger patients were significantly less likely to use aminosalicylate monotherapy when compared with patients above 65 (greatest difference age 18 to 29: aOR=0.31, 95% CI: 0.18-0.52). Younger patients with CD and UC were significantly more likely to use anti-tumor necrosis factor monotherapy than patients above 65 years (age 18 to 29: aOR=3.87, 95% CI: 2.47-6.06 and aOR=2.68, 95% CI: 1.29-5.58, respectively).

CONCLUSIONS

Older patients with IBD demonstrate significant differences in medication utilization, including more aminosalicylate monotherapy and less anti-tumor necrosis factor monotherapy compared with younger age groups. Given the aging population in the United States, these utilization patterns may have long-term implications for disease control.

Safety and Efficacy of Vedolizumab Versus Tumor Necrosis Factor α Antagonists in an Elderly IBD Population: A Single Institution Retrospective Experience

BACKGROUND

Vedolizumab is a monoclonal antibody used to treat inflammatory bowel disease (IBD). There is little known about the safety and comparative efficacy of this agent in the elderly population.

AIMS

Here, we present data on the safety and comparative efficacy of vedolizumab versus tumor necrosis factor α antagonists (anti-TNF) in elderly patients with IBD.

METHODS

This retrospective cohort study included IBD patients started on vedolizumab or anti-TNF at age 60 or older at a single tertiary IBD center. Safety was evaluated by assessing for the development of serious infection. The comparative needs for IBD-related surgery, IBD-related hospitalization, and drug discontinuation for any reason were obtained. Efficacy was assessed by comparing changes in endoscopic, histologic, and patient-report outcomes.

RESULTS

212 cases were identified-108 patients treated with vedolizumab and 104 patients treated with anti-TNF. There were no significant differences between cohorts in serious infection, surgical intervention, or IBD-hospitalization-free survival (p = NS). Drug discontinuation survival was different between anti-TNF and vedolizumab (p = 0.02) with more patients remaining on vedolizumab at the time of last follow-up (51.9% vs. 25.9%). Endoscopic remission and response rates were higher in the vedolizumab versus anti-TNF group (65.7% vs. 45.2%, p = 0.02; 80.0% vs. 59.3%, p < 0.001).

CONCLUSIONS

In a cohort of IBD patients over age 60, vedolizumab showed no statistically significant differences in infection, hospitalization, or surgical intervention-free survival as compared to anti-TNF. Vedolizumab was discontinued less frequently than anti-TNF. Patients on vedolizumab had higher rates of endoscopic remission and response.

Effectiveness and safety of vedolizumab in a matched cohort of elderly and nonelderly patients with inflammatory bowel disease: the IG-IBD LIVE study

BACKGROUND

Vedolizumab registration trials were the first to include elderly patients with moderate-to-severe ulcerative colitis (UC) or Crohn's disease (CD), but few real-life data have been reported in this population.

AIMS

We investigated the effectiveness and safety of vedolizumab in matched cohorts of elderly and nonelderly UC and CD patients.

METHODS

The Long-term Italian Vedolizumab Effectiveness (LIVE) study is a retrospective-prospective study including UC and CD patients who started vedolizumab from April 2016 to June 2017. Elderly patients (≥65 years) were matched clinically 1:2 to nonelderly patients (18-64 years); the 2 groups were followed until drug discontinuation or June 2019.

RESULTS

The study included 198 elderly (108 UC, 90 CD) and 396 matched nonelderly patients (205 UC, 191 CD). Nonelderly UC patients had a significantly higher persistence on vedolizumab compared to elderly patients (67.6% vs. 51.4%, p = 0.02). No significant difference in effectiveness was observed between elderly and nonelderly CD patients (59.4% vs. 52.4%, p = 0.32). Age ≥65 years was associated with lower persistence in UC; for CD, previous exposure to anti-TNF-α agents, Charlson comorbidity index >2 and moderate-to-severe clinical activity at baseline were associated with lower persistence. There were recorded 130 adverse events, with comparable rates between the two groups. A Charlson comorbidity index >2 was associated with an increased risk of adverse events.

CONCLUSION

Vedolizumab can be considered a safe option in elderly IBD patients. Its effectiveness in elderly UC patients may be reduced, while no age-dependent effect on effectiveness was observed in CD.

Management of Non-response and Loss of Response to Anti-tumor Necrosis Factor Therapy in Inflammatory Bowel Disease

Anti-tumor necrosis factor (anti-TNF) therapy has been successfully used as first-line biologic treatment for moderate-to-severe inflammatory bowel disease (IBD), in both “step-up” and “top-down” approaches, and has become a cornerstone of IBD management. However, in a proportion of patients the effectiveness of anti-TNF therapy is sub-optimal. Either patients do not achieve adequate initial response (primary non-response) or they lose response after initial success (loss of response). Therapeutic drug monitoring determines drug serum concentrations and the presence of anti-drug antibodies (ADAbs) and can help guide treatment optimization to improve patient outcomes. For patients with low drug concentrations who are ADAb-negative or display low levels of ADAbs, dose escalation is recommended. Should response remain unchanged following dose optimization the question whether to switch within class (anti-TNF) or out of class (different mechanism of action) arises. If ADAb levels are high and the patient has previously benefited from anti-TNF therapy, then switching within class is a viable option as ADAbs are molecule specific. Addition of an immunomodulator may lead to a decrease in ADAbs and a regaining of response in a proportion of patients. If a patient does not achieve a robust therapeutic response with an initial anti-TNF despite adequate drug levels, then switching out of class is appropriate. In conjunction with the guidance above, other factors including patient preference, age, comorbidities, disease phenotype, extra-intestinal manifestations, and treatment costs need to be factored into the treatment decision. In this review we discuss current evidence in this field and provide guidance on therapeutic decision-making in clinical situations.

Ulcerative Colitis in Adulthood and in Older Patients: Same Disease, Same Outcome, Same Risks?

The number of patients with inflammatory bowel disease (IBD) approaching an older age, together with the number of over-60-year-old patients newly diagnosed with IBD, is steadily increasing, reaching 25% of all patients. The present review focuses on late-onset ulcerative colitis (UC) and its initial disease course in comparison with that observed in younger adults in terms of extension at onset and the risk of proximal disease progression, medical treatment, surgery and hospitalization in the first years after diagnosis. We summarize the clues pointing to a milder disease course in a population which frequently presents major frailty due to comorbidities. With increasing age and thus increasing comorbidities, medical and surgical therapies frequently represent a challenge for treating physicians. The response, persistence, and risks of adverse events of conventional therapies indicated for late onset/older UC patients are examined, emphasizing the risks in this particular population, who are still being treated with prolonged corticosteroid therapy. Finally, we concentrate on data on biotechnological agents for which older patients were mostly excluded from pivotal trials. Real-life data from newer agents such as vedolizumab and ustekinumab show encouraging efficacy and safety profiles in the population of older UC patients.

Crohn's Disease of the Elderly: Unique Biology and Therapeutic Efficacy and Safety

The incidence and prevalence of inflammatory bowel disease (IBD) is increasing in the elderly population. Compared with patients with onset during younger years, patients with elderly-onset IBD have a distinct clinical presentation, disease phenotype, and natural history. Genetics contribute less to pathogenesis of disease, whereas aging-related biological changes, such as immunosenescence and dysbiosis, are associated with elderly-onset IBD. Frailty is an increasingly recognized predictor of adverse outcomes. As an increasingly wider array of biologic and small molecule therapeutic options becomes available, data regarding efficacy and safety of these agents in patients are paramount given the unique characteristics of this population.

Efficacy of Vedolizumab in a Nationwide Cohort of Elderly Inflammatory Bowel Disease Patients

BACKGROUND

The elderly inflammatory bowel disease (IBD) population has historically been under-represented in clinical trials, and data on the efficacy of biologic medications in elderly IBD patients are generally lacking. Our study aims to evaluate the efficacy of vedolizumab (VDZ) among elderly IBD patients and compare it with younger IBD patients in a nationwide population-based cohort of IBD patients.

METHODS

We conducted a retrospective cohort study of patients within the US national Veterans Affairs Healthcare System (VAHS). Patients were stratified into 2 groups based on age at the time of starting VDZ (60 years of age and older or younger than 60 years of age) with outcomes compared between the 2 groups. The primary outcome was steroid-free remission during the 6- to 12-month period after starting VDZ therapy among those patients who were on steroids when VDZ was started.

RESULTS

There were 568 patients treated with VDZ, of whom 56.7% had Crohn's disease and 43.3% had ulcerative colitis. Among them, 316 patients were on steroids when VDZ was started. The percentage of patients who were on VDZ and off steroids during the 6- to 12-month period after VDZ initiation was 46.8% and 40.1% for the younger and elderly groups, respectively (P = 0.2374). Rates of hospitalization for an IBD-related reason within 1 year of VDZ start among the whole cohort were nearly identical in the younger and elderly groups (11.2% vs 11.3%, P = 0.9737). Rates of surgery for an IBD-related reason within 1 year of VDZ start were also similar between the young and elderly (3.9% vs 3.9%, P = 0.9851).

CONCLUSIONS

In a nationwide real-world retrospective cohort study of elderly IBD patients, we found that the efficacy of VDZ was similar among younger and older IBD patients and comparable with the published data in clinical trials.

Elderly onset age is associated with low efficacy of first anti-tumor necrosis factor treatment in patients with inflammatory bowel disease

The outcomes of patients with elderly onset (EO) inflammatory bowel disease (IBD) treated with anti-tumor necrosis factor (TNF) remains uncertain. The present study evaluated the efficacy and safety of anti-TNF treatment for bio-naïve EO-IBD. Elderly patients were defined as those 60 years and older, and further divided into those with EO (Elderly-EO) and those with non-elderly onset (Elderly-NEO). A total of 432 bio-naïve patients were enrolled in this multicenter observational study, comprising 55 with Elderly-EO (12.7%), 25 with Elderly-NEO (5.8%), and 352 under age 60 (Non-elderly, 81.5%). After 52 weeks of anti-TNF treatment, clinical and steroid-free remission rates were significantly lower in Elderly-EO than in Non-elderly (37.7% and 60.8%; P = 0.001, and 35.9% and 57.8%; P = 0.003, respectively), and comparable between Elderly-NEO and Non-elderly. Multivariate analysis revealed that elderly onset was a significant factor for both clinical remission (OR, 0.49, 95% CI 0.25–0.96) and steroid-free remission (OR, 0.51, 95% CI 0.26–0.99) after 52 weeks of anti-TNF treatment. The rate of cumulative severe adverse events was significantly higher in Elderly-EO than in Non-elderly (P = 0.007), and comparable between Elderly-NEO and Non-elderly. In conclusion, anti-TNF treatment for bio-naïve EO-IBD may be less effective and raise safety concerns.

Influence of comorbidities on treatment considerations for first-line biologic prescribing in patients with inflammatory bowel disease in the UK

BACKGROUND

Anti-tumour necrosis factor (anti-TNF) therapies are the most commonly used biologics for inflammatory bowel disease (IBD), but for patients with a comorbidity, newer agents may be a more appropriate treatment choice.

AIMS

To investigate the impact of comorbidities in patients with IBD, on first-line biologic prescribing habits of IBD-specialist healthcare practitioners in the UK.

METHODS

IBD-specialist physicians and nurses were asked to answer an online survey, considering different prescribing scenarios in ulcerative colitis (UC) and Crohn's disease (CD). Respondents could indicate a preference for anti-TNFs or newer biologics, both in the absence and presence of 10 common comorbidities.

RESULTS

A total of 120 IBD-specialist healthcare professionals (HCPs) completed the survey. In the absence of comorbidities, anti-TNFs were favoured; infliximab was the preferred first-line biologic in both UC and CD (43% and 37% of respondents, respectively). On introducing comorbidities, the largest shift in prescribing behaviour was for vedolizumab, with preference increasing by 27% and 21%, compared with infliximab, which fell by 14% and 9% in UC and CD, respectively. Chronic/recurring infection (46%), congestive heart failure (≤44%) and malignancies (≤43%) were the most commonly selected comorbidities for vedolizumab treatment.

CONCLUSIONS

Clinicians adapt their biologic prescribing habits in patients with IBD with comorbidities, considering known contraindications and precautions. A preference for vedolizumab is evident in many cases, however, for several comorbid scenarios, including demyelinating disorders, chronic obstructive pulmonary disease and malignancy, anti-TNFs are prescribed despite known risks. It is important that continual re-evaluation of the IBD treatment landscape is undertaken by HCPs, in alignment with recommendations in published guidelines.

A review of the therapeutic management of Crohn's disease

Crohn's disease is a chronic inflammatory, relapsing-remitting, and progressive gastrointestinal disorder with an often-negative impact on the physical, emotional, and psychological well-being. Over the past two decades, the medical compendium for the treatment of Crohn's disease has increased significantly, enabling treatment beyond symptoms. Indeed, early and timely use of effective medical therapy has been reflected by improved outcomes with reduction in surgery and ability to achieve clinical and endoscopic remission, reduce corticosteroid dependance, and prevent long-term complications in more patients. In this review, we discuss the key milestones in the medical management of Crohn's disease.

Inflammatory Bowel Disease Patients Who Respond to Treatment with Anti-tumor Necrosis Factor Agents Demonstrate Improvement in Pre-treatment Frailty

BACKGROUND

Frailty may be a risk factor for complications in inflammatory bowel diseases (IBD) patients. We examined the impact of treatment on IBD patients who were frail prior to treatment and identified predictors of post-treatment change in frailty.

METHODS

In an electronic health record-based cohort of IBD patients initiating anti-tumor necrosis factor (TNF)-α agents, we applied a validated claims-based frailty index to determine frailty in the 1 year prior to and after treatment initiation. We characterized treatment non-response using a composite outcome of IBD-related hospitalization, surgery, change in therapy, or initiation of systemic steroids. We constructed multivariable logistic regression models to identify determinants of post-treatment frailty.

RESULTS

The 1210 patients initiating anti-TNF therapy had a median age of 30 years; 20% were ≥ 50 years. In the first year after anti-TNF initiation, 40% were non-responders. Many more treatment non-responders were frail in the year following treatment compared with treatment responders (27% vs 7%, p < 0.001). Pre-treatment frailty (OR 2.01, 95% CI 1.35-3.00) and prior IBD-related hospitalization (OR 1.63, 95% CI 1.15-2.30) were independently predictive of higher likelihood of post-treatment frailty. Therapy response was associated with a lower likelihood (OR 0.24, 95% CI 0.16-0.34) of post-treatment frailty. Nearly 85% of patients who were frail prior to treatment demonstrated improvement in frailty following treatment CONCLUSIONS: Response to anti-TNF therapy is an important determinant of post-treatment frailty in patients with IBD. Our findings suggest that effectively treating inflammatory states in older patients with IBD may improve frailty.

Analysis of the disease activity of ulcerative colitis with and without concomitant primary sclerosing cholangitis: An investigation using a nationwide database in Japan

Aims

Primary sclerosing cholangitis (PSC) is a relatively common complication of ulcerative colitis (UC). Only a few studies have investigated the impact of PSC on the clinical course of UC, and their conclusions are contradictory. Therefore, we aimed to compare the disease activity of UC with and without PSC.

Methods and Results

We collected UC patient data using the Diagnosis Procedure Combination database system in Japan and classified eligible admissions into two groups based on their diagnosis of either UC alone or UC associated with PSC. We then compared therapeutic details (medical treatment and surgery) between the two groups. Multivariable logistic regression analysis and propensity score matching was also performed. The rates of systemic steroid injection and infliximab administration in patients with PSC were lower than those in patients without PSC (21% vs. 28%, P = 0.012, 9.6% vs. 16%, P = 0.01, respectively). The rates of surgery, colorectal cancer, duration of hospital stay, and in-hospital mortality did not differ between the two groups. Multivariable analysis revealed that concomitant PSC was a clinical factor that reduced the odds of systemic steroid injection (odds ratio [OR] = 0.66, 95% confidence interval [CI]: 0.49-0.90, P = 0.008) and infliximab (OR = 0.48, 95% CI: 0.32-0.74, P = 0.0008) administration.

Conclusion

UC patients with PSC might have less UC disease activity than those with UC alone.

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.

Aging and IBD: A New Challenge for Clinicians and Researchers

Evidence from recent epidemiological data suggests that the patient population with inflammatory bowel disease (IBD) is chronologically aging. As these individuals become older, cellular senescence leads to a state of chronic inflammation. This process, known as inflammaging, is thought to be closely linked with biological aging and may be upregulated within IBD. As a consequence, we see an increased risk of aging-related disorders within IBD. In addition, we see that frailty, which results from physiologic decline, is increasing in prevalence and is associated with adverse clinical outcomes in IBD. As such, in this review we explore the potential overlapping biology of IBD and aging, discuss the risk of aging-related disorders in IBD, and describe frailty and its relation to clinical outcomes within IBD. Finally, we discuss current considerations for clinical care and potential research avenues for further investigation.

Real world evidence of the association between medication and life expectancy in elderly inflammatory bowel disease: a population-based cohort study

BACKGROUND

Life expectancy in people with inflammatory bowel disease (IBD) has increased but remains shorter than in people without IBD. We describe the life expectancy associated with IBD therapies among the growing number of older adults living with IBD.

METHODS

Older adults (≥ 65 years) with IBD were identified from population-based health administrative data using a validated algorithm. Life expectancy on patients' 65th birthday, stratified by sex, was calculated using a period life table approach from age- and sex-specific mortality rates among patients receiving immunomodulator monotherapy, biologic monotherapy, combination therapy, mesalamine, systemic steroids, and no therapy.

RESULTS

Among 28,260 older adults with IBD (239,125 person-years of follow-up), life expectancy at 65 years was longest for patients taking mesalamine (females: 22.1 years, 95% CI 21.8-22.5; males: 19.6 years, 95% CI 19.3-20.0) and shortest for patients taking steroids (females: 11.7 years, 95% CI 11.0-12.4; males 10.3 years, 95% CI 9.7-10.8). Life expectancy was similar for patients receiving immunomodulator monotherapy and biologic monotherapy. Immunomodulator monotherapy was associated with a reduction in life expectancy compared to combination therapy by 5.1 (95% CI 2.3-7.8) in females and 2.8 years (95% CI 0.1-5.5) in males.

CONCLUSIONS

Life expectancy varies across therapies used for IBD, with differences likely arising from a combination of medication effectiveness, safety profiles, disease severity, and comorbid conditions. These considerations should be balanced when deciding on a therapeutic approach for the management of IBD in older adults.

Frailty Is Independently Associated with Mortality and Readmission in Hospitalized Patients with Inflammatory Bowel Diseases

BACKGROUND & AIMS

Old age must be considered in weighing the risks of complications vs benefits of treatment for patients with inflammatory bowel diseases (IBD). We conducted a nationally representative cohort study to estimate the independent effects of frailty on burden, costs, and causes for hospitalization in patients with IBD.

METHODS

We searched the Nationwide Readmissions Database to identify 47,402 patients with IBD, hospitalized from January through June 2013 and followed for readmission through December 31, 2013. Based on a validated hospital frailty risk scoring system, 15,507 patients were considered frail and 31,895 were considered non-frail at index admission. We evaluated the independent effect of frailty on longitudinal burden and costs of hospitalization, inpatient mortality, risk of readmission and surgery, and reasons for readmission.

RESULTS

Over a median follow-up time of 10 months, adjusting for age, sex, income, comorbidity index, depression, obesity, severity, and indication for index hospitalization, frailty was independently associated with 57% higher risk of mortality (adjusted hazard ratio [aHR], 1.57; 95% CI, 1.34-1.83), 21% higher risk of all-cause readmission (adjusted hazard ratio [HR], 1.21; 95% CI, 1.17-1.25), and 22% higher risk of readmission for severe IBD (aHR, 1.22; 95% CI, 1.16-1.29). Frail patients with IBD spent more days in the hospital annually (median 9 days; interquartile range, 4-18 days vs median 5 days for non-frail patients; interquartile range, 3-10 days; P < .01) with higher costs of hospitalization ($17,791; interquartile range, $8368-$38,942 vs $10,924 for non-frail patients, interquartile range, $5571-$22,632; P < .01). Infections, rather than IBD, were the leading cause of hospitalization for frail patients.

CONCLUSIONS

Frailty is independently associated with higher mortality and burden of hospitalization in patients with IBD; infections are the leading cause of hospitalization. Frailty should be considered in treatment approach, especially in older patients with IBD.
