Safety and Efficacy of Tumor Necrosis Factor Antagonists in Older Patients With Ulcerative Colitis: Patient-Level Pooled Analysis of Data From Randomized Trials

Similar Efficacy of Mesalazine in Adult and Older Adult Ulcerative Colitis Patients: Post Hoc Analysis of a Randomized Noninferiority Trial of 1600 mg vs 400 mg Tablets

BACKGROUND

The efficacy data on treatment in older adults are scarce, while the greatest increase in ulcerative colitis (UC) prevalence is observed in age groups of individuals 40 to 65 years of age and ≥65 years of age.

AIM

We assessed the difference in rates of clinical and endoscopic response and remission in UC adults (≤60 years) and older adults (>60 years) treated with mesalazine.

METHODS

We performed a post hoc analysis of data from a phase 3 noninferiority trial of 817 UC patients treated with mesalazine for 8 and additional 26 weeks in a double-blind and open-label study, respectively. We used Wilcoxon rank sum or chi-square test to analyze differences between groups and multivariable logistic regression to determine the associations between endoscopic remission as outcome (Mayo endoscopic subscore [MES] = 0 or ≤1) and independent variables including disease duration, baseline MES, age, sex, comedications, and comorbidities.

RESULTS

Older adults had a longer disease duration, a higher number of comorbidities, concomitant medications, and higher baseline MES (2.38 ± 0.486 in older adults vs 2.26 ± 0.439 in adults; P = .008) compared with adults. We observed no difference in rates of combined clinical and endoscopic remission, clinical remission and response, and endoscopic remission and response at week 8 and 38 post-treatment. In addition to other well-known predictors of worse outcome, patients with ≥3 comedications were less likely to achieve an MES = 0 at week 8 and 38 and an MES ≤1 at week 38.

CONCLUSIONS

We observed similar efficacy of mesalazine in adult and older adult UC patients. The increased comedication number rather than age may decrease effectiveness of UC medications, highlighting the importance of healthy aging.

Clin-STAR Corner: Practice-Changing Advances at the Interface of Gastroenterology & Geriatrics

With nearly 60 million Americans aged 65 and older, gastrointestinal (GI) conditions are a leading cause of healthcare utilization in this population. Despite this, older adults remain underrepresented in GI clinical trials and research, limiting evidence-based care. This review highlights three pivotal studies addressing this gap: (1) proton pump inhibitors, which are commonly used to treat gastroesophageal reflux disease, are not associated with the later development of dementia; (2) undertreatment of chronic inflammation among older adults with inflammatory bowel disease is associated with a higher rate of adverse events compared to treatment with anti-TNF therapy, a biologic agent; (3) the majority (85%) of surveillance colonoscopies among older adults with a life expectancy of ≥ 10 years did not yield colorectal cancer, advanced dysplasia, or ≥ 3 polyps.

Older Adults With Inflammatory Bowel Disease Are at Higher Risk of Developing Antibodies to Infliximab

Although older age is thought to confer immunosenescence, we found that older adults with inflammatory bowel disease are independently at higher risk to develop antibodies to infliximab. Additionally, older adults are less likely to receive escalated doses of infliximab.

Short-term effectiveness and safety of ustekinumab and vedolizumab in elderly and non-elderly patients with Crohn's disease: a comparative study

Background

Inflammatory bowel disease (IBD) presents unique challenges in elderly patients due to comorbidities and treatment-related risks.

Objectives

This study evaluates ustekinumab (UST) and vedolizumab (VDZ) efficacy and safety in elderly Crohn's disease (CD) patients.

Design

A retrospective cohort study at a tertiary medical center.

Methods

CD patients aged ⩾60 years (elderly) treated with UST, compared to non-elderly (<60 years) patients treated with UST and elderly patients treated with VDZ. Clinical response was evaluated using the Harvey-Bradshaw index (HBI) and clinical biomarkers, alongside monitoring steroid use, hospitalization rates, treatment persistence, and surgical interventions.

Results

The study included 166 CD patients: 32 elderly and 65 non-elderly patients treated with UST, and 69 elderly patients treated with VDZ. The mean duration of follow-up was 10.8 ± 2.8 months in the non-elderly group, 9.97 ± 3.28 months in the elderly UST group, and 10.0 ± 3.29 months in the VDZ group. Elderly UST patients were more likely to receive corticosteroids at initiation than non-elderly UST patients (44% vs 14%, p = 0.001). At 12 months, clinical response rates did not significantly differ between elderly and non-elderly UST groups, respectively (48% vs 40%, p = 0.5). However, elderly UST patients exhibited higher hospitalization rates over time compared to non-elderly UST patients (6-month: 19% vs 6.2%, p = 0.077; 12-month: 19% vs 4.6%, p = 0.055; log-rank p = 0.004). No significant differences were observed in clinical response and remission rates between elderly UST and elderly VDZ patients at 6 and 12 months. At 6 months, a higher hospitalization rate was observed in the UST group (19% vs 4.3% p = 0.027), but this difference did not persist over time.

Conclusion

UST and VDZ are effective and safe treatments for elderly CD patients, despite higher hospitalization rates compared to non-elderly patients, likely due to age-related complications.

Common Mistakes in Managing Patients with Inflammatory Bowel Disease

Introduction: Errors are very common in medical practice and in particular, in the healthcare of patients with inflammatory bowel disease (IBD); however, most of these can be prevented. Aim: To address common errors in the management of IBD. Methods: Our approach to this problem consists in identifying mistakes frequently observed in clinical practice (according to our experience) in the management of patients with IBD, then reviewing the scientific evidence available on the subject, and finally proposing the most appropriate recommendation for each case. Results: The most common mistakes in the management of IBD include those related to diagnosis and differential diagnosis, prevention, nutrition and diet, treatment with different drugs (mainly 5-aminosalicylates, corticosteroids, thiopurines, and anti-TNF agents), extraintestinal manifestations, anemia, elderly patients, pregnancy, and surgery. Conclusions: Despite the availability of guidelines for both disease management and preventive aspects of IBD care, a considerable variation in clinical practice still remains. In this review, we have identified common mistakes in the management of patients with IBD in clinical practice. There is a clear need for a greater dissemination of clinical practice guidelines among gastroenterologists and for the implementation of ongoing training activities supported by scientific societies. Finally, it is desirable to follow IBD patients in specialized units, which would undoubtedly be associated with higher-quality healthcare and a lower likelihood of errors in managing these patients.

Selecting first-line advanced therapy for ulcerative colitis: A clinical application of personalized medicine

Ulcerative colitis (UC) is a chronic autoimmune inflammatory disease that affects the colon, leading to symptoms of bloody diarrhea, abdominal cramps, and urgency. The treatment of UC has evolved over the past few decades from locally active anti-inflammatory compounds to more selective therapies that target specific arrays of the immune system. The challenge of selecting the first advanced therapy became apparent in this rapidly expanding landscape of medications. No current investigational tools, such as genetic, immunologic, or biological markers, can guide the identification of the safest and most effective therapeutic option for each patient. Hence, physicians must carefully assess patient/disease characteristics and match them with the most suitable drug through a clinically driven assessment. In this paper, we outline patient and drug characteristics that play a role in selecting first-line advanced therapies for UC and propose an algorithm for selection.

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.

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.

The 2023 Impact of Inflammatory Bowel Disease in Canada: Special Populations-IBD in Seniors

Approximately one out of every 88 seniors has inflammatory bowel disease (IBD), and this is expected to increase in the future. They are more likely to have left-sided disease in ulcerative colitis, and isolated colonic disease in Crohn's disease; perianal disease is less common. Other common diagnoses in the elderly must also be considered when they initially present to a healthcare provider. Treatment of the elderly is similar to younger persons with IBD, though considerations of the increased risk of infections and malignancy must be considered when using immune modulating drugs. Whether anti-TNF therapies increase the risk of infections is not definitive, though newer biologics, including vedolizumab and ustekinumab, are thought to be safer with lower risk of adverse events. Polypharmacy and frailty are other considerations in the elderly when choosing a treatment, as frailty is associated with worse outcomes. Costs for IBD-related hospitalizations are higher in the elderly compared with younger persons. When elderly persons with IBD are cared for by a gastroenterologist, their outcomes tend to be better. However, as elderly persons with IBD continue to age, they may not have access to the same care as younger people with IBD due to deficiencies in their ability to use or access technology.

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.

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.

Management of inflammatory bowel diseases in older adults

The burden of inflammatory bowel disease (IBD) in older adults (ie, aged over 60 years old) is increasing due to a combination of an ageing population with compounding prevalence of IBD and increasing incidence of elderly-onset (ie, onset over the age of 60 years) IBD. Despite the increasing prevalence of IBD, there is a paucity of evidence on which to base management of older adults with IBD, leading to substantial variability in care. This population is under-represented in clinical trials and has a high burden of chronic corticosteroid use, low uptake of steroid-sparing immunosuppressive agents, and high rates of unplanned health-care use and disability. Management of IBD in older adults requires carefully weighing an individual patient's risk of IBD-related complications, IBD-directed immunosuppressive therapy, and non-IBD comorbidities. A deeper understanding of biological and functional age, dynamic risk stratification strategies (including frailty-based risk assessment tools), comparative effectiveness and safety of current therapies and treatment strategies, and shared decision making to inform treatment goals and targets is needed to improve outcomes in older adults with IBD. In this Review, we discuss the epidemiology, natural history, pathophysiology, and medical and surgical management of older individuals living with IBD and identify key research gaps and approaches to address them.

Elderly Patients with Moderate-To-Severe Ulcerative Colitis Are More Likely to Have Treatment Failure and Adverse Outcome

BACKGROUND AND AIM

The aim of this study was to compare therapeutic responses and prognosis between elderly and nonelderly ulcerative colitis (UC) patients with moderate-to-severe activity.

METHODS

148 UC patients with moderate-to-severe activity hospitalized between 2000 and 2019 were enrolled consecutively, including 74 patients with the age of diagnosis over 60 years and 74 patients diagnosed less than 60 years. Patients were matched by gender, duration (±15%), disease activity, and admission time (±1 year). They were followed up until the latest medical record or December 2019. The primary outcome was UC-related colectomy or death.

RESULTS

148 patients were followed over median 37.5 months. For steroid use, 76.8% of elderly UC patients were responsive, lower than that in adult group (85.7%). A decreased level of clinical activity index (2.0 [-1.5 to 4.00] vs. 6.0 [3.0-8.0], p < 0.001), reduction of C-reactive protein (23.9 [3.5-65.5] vs. 27.8 [9.7-58.1] mg/L), and erythrocyte sedimentation rate (9.0 [-1.3 to 30.5] vs. 15.5 [3.8-36.5] mm/h) at 4 weeks after steroid induction was less obvious in the elderly. More elderly patients manifested steroid dependence and resistance. 28.4% of elderly UC patients took colectomy, remarkably more than adult patients (12.2%), which also occurred earlier (8.0 [0.5-44.75] vs. 39.5 [12-57.38] months, p = 0.001). Aging (hazard ratio [HR] 2.868, 95% confidence interval [CI]: 1.290-6.375, p = 0.01), male, steroid resistance, and occurrence of complications were independently related to colectomy. The rate of serious infections was significantly higher in the elderly (55.4% vs. 35.1%, p = 0.013), mainly including cytomegalovirus infection, bacterial infection, and extraintestinal infection. Aging (odds ratio [OR] 2.774, 95% CI: 1.355-5.675, p = 0.015), extensive colonic involvement, steroid resistance, and biologics usage were independently associated with a high risk of concomitant infections.

CONCLUSION

Elderly patients with moderate-to-severe UC experienced more treatment failure and increased risk of UC-related colectomy, mortality, and severe infections, predicting demand for more strict and individualized management.

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

INTRODUCTION

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

METHODS

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

RESULTS

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

DISCUSSION

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

Effectiveness, safety, and drug sustainability of biologics in elderly patients with inflammatory bowel disease: A retrospective study

BACKGROUND

Biologic therapy resulted in a significant positive impact on the management of inflammatory bowel disease (IBD) however data on the efficacy and side effects of these therapies in the elderly is scant.

AIM

To evaluate retrospectively the drug sustainability, effectiveness, and safety of the biologic therapies in the elderly IBD population.

METHODS

Consecutive elderly (≥ 60 years old) IBD patients, treated with biologics [infliximab (IFX), adalimumab (ADAL), vedolizumab (VDZ), ustekinumab (UST)] followed at the McGill University Inflammatory Bowel Diseases Center were included between January 2000 and 2020. Efficacy was measured by clinical scores at 3, 6-9 and 12-18 mo after initiation of the biologic therapy. Patients completing induction therapy were included. Adverse events (AEs) or serious AE were collected during and within three months of stopping of the biologic therapy.

RESULTS

We identified a total of 147 elderly patients with IBD treated with biologicals during the study period, including 109 with Crohn's disease and 38 with ulcerative colitis. Patients received the following biologicals: IFX (28.5%), ADAL (38.7%), VDZ (15.6%), UST (17%). The mean duration of biologic treatment was 157.5 (SD = 148) wk. Parallel steroid therapy was given in 34% at baseline, 19% at 3 mo, 16.3% at 6-9 mo and 6.5% at 12-18 mo. The remission rates at 3, 6-9 and 12-18 mo were not significantly different among biological therapies. Kaplan-Meyer analysis did not show statistical difference for drug sustainability (P = 0.195), time to adverse event (P = 0.158) or infection rates (P = 0.973) between the four biologics studied. The most common AEs that led to drug discontinuation were loss of response, infusion/injection reaction and infection.

CONCLUSION

Current biologics were not different regarding drug sustainability, effectiveness, and safety in the elderly IBD population. Therefore, we are not able to suggest a preferred sequencing order among biologicals.

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.

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.

Positioning biologics in the treatment of IBD: A practical guide - Which mechanism of action for whom?

The number of available biological therapies have doubled over the last 10 years and the arrival of novel molecules (interleukin 23p19 inhibitors) is ongoing alongside the development of small molecules. As a result of this vast landscape of treatment, positioning advanced therapies (according to clinical situation, efficacy and safety) is of paramount importance to providing personalized, appropriate IBD treatment. In this publication the recent available literature is summarized for practical integration into clinical practice including comparative efficacy data, patient and disease demographics. We refer to recent publications and expert opinion in order to facilitate the decision making process of positioning biologicals IBD treatment.

How to Choose the Biologic Therapy in a Bio-Naïve Patient with Inflammatory Bowel Disease

The availability of biologic therapies in inflammatory bowel disease (IBD) is increasing significantly. This represents more options to treat patients, but also more difficulties in choosing the therapies, especially in the context of bio-naïve patients. Most evidence of safety and efficacy came from clinical trials comparing biologics with placebo, with a lack of head-to-head studies. Network meta-analysis of biologics and real-world studies have been developed to solve this problem. Despite the results of these studies, there are also other important factors to consider before choosing the biologic, such as patient preferences, comorbidities, genetics, and inflammatory markers. Given that resources are limited, another important aspect is the cost of biologic therapy, since biosimilars are widely available and have been demonstrated to be effective with a significant decrease in costs. In this review, we summarize the evidence comparing biologic therapy in both Crohn´s disease (CD) and ulcerative colitis (UC) in different clinical situations. We also briefly synthesize the evidence related to predictors of biologic response, as well as the biologic use in extraintestinal manifestations and the importance of the drug-related costs.

Clinical characteristics of ulcerative colitis in elderly patients

The incidence of ulcerative colitis (UC) in elderly patients is increasing. Elderly UC patients are likely to exhibit distinct features both at diagnosis and during follow-up. Age-related problems, including complications, immune dysfunction, and multidrug use, make the diagnosis and treatment of elderly UC more challenging. Suboptimal treatment considering adverse events leads to poor clinical outcome in elderly UC patients. Here, we reviewed the epidemiology, clinical presentation, medical therapy, colorectal cancer surveillance of UC in elderly patients.

[Treatment of Inflammatory Bowel Disease in Elderly Patients - What Are Different and What Should We Know?]

As the incidence of inflammatory bowel disease (IBD) are increasing with an ageing population, the incidence and prevalence of IBD in the elderly continue to increase. Older IBD patients can be classified into two groups; elderly-onset IBD patients and elderly IBD patients who were diagnosed at a young age and transitioning into advanced age. Clinicians must consider elderly-onset specific phenotypes or prognosis and age-related concerns in the treatment of elderly IBD patients. There is a paucity of evidence whether there is a different disease process when IBD occurs in older age yet. Clinicians may expect similar therapeutic effects in older and younger patients in drug selection, but since older patients are often excluded from clinical trials, evidence to support this assumption is currently lacking. Also, the risk of side effects may be higher in elderly patients. Therefore, when making management decisions in the elderly, clinicians should assess an individual's frailty rather than only considering an individual's chronological and biological age. Knowing specific requirements for managing older IBD patients may help to make an appropriate therapeutic strategy for this patient group.

The effect of aging on infliximab exposure and response in patients with inflammatory bowel diseases

AIMS

Controversies regarding infliximab treatment in elderly patients with inflammatory bowel diseases remain. We evaluated the effect of patient's age on infliximab exposure, efficacy and safety.

METHODS

Retrospective case-control data of patients receiving infliximab induction treatment were analysed. A population pharmacokinetic model was developed to estimate individual pharmacokinetic parameters. A logistic regression model was used to investigate the effect of exposure on endoscopic remission. Repeated time-to-event models were developed to describe the hazard of safety events over time.

RESULTS

A total of 104 patients (46 elderly, ≥65 years) were included. A two-compartment population pharmacokinetic model with linear elimination adequately described the data. Infliximab clearance decreased with older age, higher serum albumin, lower fat-free mass, lower C-reactive protein and absence of immunogenicity. Yet, infliximab exposure was not significantly different between elderly and nonelderly. Regardless of age, an infliximab trough concentration at week (w)14 of 15.6 mg/L was associated with a 50% probability of attaining endoscopic remission between w6 and w22. Infliximab exposure during induction treatment was not a risk factor of (severe) adverse events. The hazard of severe adverse events and malignancy increased by 2% and 7%, respectively, with increasing year of age. Concomitant immunomodulator use increased the hazard of infection by 958%, regardless of age.

CONCLUSIONS

Elderly patients attained infliximab exposure and endoscopic remission similarly to nonelderly patients. Therefore, the same infliximab trough concentration target can be used in therapeutic drug monitoring. The hazards of severe adverse events and malignancy increased with age, but not with infliximab exposure.

Clinical Characteristics and Long-term Prognosis of Elderly-Onset Ulcerative Colitis in a Population-Based Cohort in the Songpa- Kangdong District of Seoul, Korea

Background/Aims

We aimed to evaluate the clinical characteristics and long-term prognosis of elderly-onset ulcerative colitis (EOUC) in Korean patients over a 30-year period using a well-established population-based cohort in the Songpa-Kangdong district of Seoul, Korea.

Methods

Clinical characteristics and prognosis were compared between two groups EOUC, defined as UC diagnosed in individuals aged ≥60 years and non-EOUC (N-EOUC), defined as UC diagnosed in individuals aged 18 to 59 years.

Results

We identified 99 patients with EOUC (10.3%) and 866 patients with N-EOUC (89.7%) between 1986 and 2015. During the median follow-up of 104.5 months, the overall exposure to medications was comparable between patients with EOUC and N-EOUC (p=0.091 for corticosteroids, p=0.794 for thiopurines, and p=0.095 for anti-tumor necrosis factor agents). The cumulative risks of disease outcomes were also comparable between patients with EOUC and N-EOUC (22.4% vs 30.4% for proximal disease extension [p=0.351], 11.9% vs 18.1% for hospitalization [p=0.240], and 2.3% vs 1.8% for colectomy [p=0.977]) at 10 years after diagnosis. Multivariate Cox regression analysis revealed that corticosteroid use at diagnosis was an independent predictor of proximal disease extension (hazard ratio [HR], 6.216; 95% confidence interval [CI], 1.314 to 28.826) and hospitalization (HR, 11.241; 95% CI, 3.027 to 41.742) in patients with EOUC.

Conclusions

In this population-based study from Korea, the pattern of medication use seemed comparable between the EOUC and N-EOUC groups. Moreover, patients with EOUC and those with N-EOUC have a similar disease course in terms of proximal disease extension, hospitalization, and colectomy. (Gut Liver 2021;15-751)

Patient's profiling for therapeutic management of inflammatory bowel disease: a tailored approach

Introduction: Several biological drugs and a new small molecule are available for the treatment of Crohn's disease and ulcerative colitis. However, to date, no reliable predictors of response to treatment have yet been identified. Areas covered: We focused on studies evaluating the therapeutic management of patients with chronic inflammatory bowel diseases in order to identify any predictive factors of response to drugs and to guide therapeutic decisions based on patient and disease characteristics. Expert opinion: The heterogeneity of literature data, the main retrospective nature of the scientific evidence, and the lack of comparative head-to-head trials are the most relevant limitations for identifying factors predicting drug response. In the near future, a personalized approach to patients with chronic inflammatory diseases will be based on patient's profile to define not only the best drug to use, but also the appropriate follow-up, and the possibility of home care.

Fighting the Host Reaction to SARS-COv-2 in Critically Ill Patients: The Possible Contribution of Off-Label Drugs

The severe acute respiratory syndrome coronavirus 2 (SARS-COv-2) is the etiologic agent of the 2019 coronavirus disease (COVID19). The majority of infected people presents flu like symptoms and among them 15–20% develops a severe interstitial pneumonitis (IP) that may eventually evolve in acute respiratory distress syndrome (ARDS). IP is caused by the viral glycoprotein spike (S) binding to the angiotensin converting enzyme 2 (ACE2) expressed on the surface of alveolar pneumocytes. The virus is recognized by the “pattern recognition receptors” (PRR) of the immune cells that release cytokines activating more immune cells that produce a large number of pro-inflammatory cytokines, tissue factors and vasoactive peptides. Affected patients might develop the “cytokine storm syndrome,” a fulminant and fatal hypercytokinaemia with multiorgan failure. In patients infected by SARS-COv-2 increase in T-helper 2 (TH2) cytokines (IL-4 and IL10) are reported in addition to the T-helper 1 (TH1) cytokines (IL1B, IFNγ, IP10, and MCP1) previously detected in other coronavirus infections. Cytokines and other molecules involved in immune response and inflammation are conceivable therapeutic targets for IP and ARDS, improving symptoms and decreasing intensive care unit admissions. To this aim off label drugs may be used taking into consideration the window timing for immunosuppressive drugs in virus infected patients. Some off label therapeutic options and preclinical evidence drugs are herein considered.
