Geriatric inflammatory bowel disease: phenotypic presentation, treatment patterns, nutritional status, outcomes, and comorbidity

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Efficacy and safety of biological treatment for inflammatory bowel disease in elderly patients: Results from a GETECCU cohort

INTRODUCTION

Biological therapies used for the treatment of inflammatory bowel disease (IBD) have shown to be effective and safe, although these results were obtained from studies involving mostly a young population, who are generally included in clinical trials. The aim of our study was to determine the efficacy and safety of the different biological treatments in the elderly population.

METHODS

Multicenter study was carried out in the GETECCU group. Patients diagnosed with IBD and aged over 65 years at the time of initiating biological therapy (infliximab, adalimumab, golimumab, ustekinumab or vedolizumab) were retrospectively included. Among the patients included, clinical response was assessed after drug induction (12 weeks of treatment) and at 52 weeks. Patients' colonoscopy data in week 52 were assessment, where available. Regarding complications, development of oncological events during follow-up and infectious processes occurring during biological treatment were collected (excluding bowel infection by cytomegalovirus).

RESULTS

A total of 1090 patients were included. After induction, at approximately 12-14 weeks of treatment, 419 patients (39.6%) were in clinical remission, 502 patients (47.4%) had responded without remission and 137 patients (12.9%) had no response. At 52 weeks of treatment 442 patients (57.1%) had achieved clinical remission, 249 patients had responded without remission (32.2%) and 53 patients had no response to the treatment (6.8%). Before 52 weeks, 129 patients (14.8%) had discontinued treatment due to inefficacy, this being significantly higher (p<0.0001) for Golimumab - 9 patients (37.5%) - compared to the other biological treatments analyzed. With respect to tumor development, an oncological event was observed in 74 patients (6.9%): 30 patients (8%) on infliximab, 23 (7.14%) on adalimumab, 3 (11.1%) on golimumab, 10 (6.4%) on ustekinumab, and 8 (3.8%) on vedolizumab. The incidence was significantly lower (p=0.04) for the vedolizumab group compared to other treatments. As regards infections, these occurred in 160 patients during treatment (14.9%), with no differences between the different biologicals used (p=0.61): 61 patients (19.4%) on infliximab, 39 (12.5%) on adalimumab, 5 (17.8%) on golimumab, 22 (14.1%) on ustekinumab, and 34 (16.5%) on vedolizumab.

CONCLUSIONS

Biological drug therapies have response rates in elderly patients similar to those described in the general population, Golimumab was the drug that was discontinued most frequently due to inefficacy. In our experience, tumor development was more frequent in patients who used anti-TNF therapies compared to other targets, although its incidence was generally low and that this is in line with younger patients based on previous literature.

Safety of full bowel preparation and colonoscopy in elderly patients with ulcerative colitis: A real-world multicenter retrospective cohort study

Background

The number of elderly patients with ulcerative colitis (UC) has been increasing worldwide. Complications are common in elderly patients who undergo colonoscopy, raising doubts about whether colonoscopy should be performed in the same way in this age group as in younger patients. The aim of this study was to determine the safety of full bowel preparation and colonoscopy in elderly patients with UC.

Methods

We retrospectively reviewed a cohort of patients with UC who had visited any of the 12 hospitals and were registered in our inflammatory bowel disease database. We compared complications associated with colonoscopy and bowel preparation and relapse of UC after colonoscopy in 133 patients aged ≥65 years with UC (the elderly group) and 116 randomly selected patients aged <65 years with UC (the non-elderly group).

Results

Nine elderly patients were not referred for colonoscopy by their physicians because of poor performance status or advanced age. There was no significant between-group difference in the complication rate (p = 0.57) or frequency of relapse of UC after colonoscopy (p = 0.67).

Conclusions

The findings of this study indicate that colonoscopy can be performed as safely in elderly patients with UC as in their younger counterparts. However, our results also indicate that colonoscopy is often avoided in elderly patients, possibly because of concerns about safety.

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.

Epidemiology and clinical course of late onset inflammatory bowel disease

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

Altered DNA methylation within DNMT3A, AHRR, LTA/TNF loci mediates the effect of smoking on inflammatory bowel disease

This work aims to investigate how smoking exerts effect on the development of inflammatory bowel disease (IBD). A prospective cohort study and a Mendelian randomization study are first conducted to evaluate the association between smoking behaviors, smoking-related DNA methylation and the risks of Crohn's disease (CD) and ulcerative colitis (UC). We then perform both genome-wide methylation analysis and co-localization analysis to validate the observed associations. Compared to never smoking, current and previous smoking habits are associated with increased CD (P = 7.09 × 10-10) and UC (P < 2 × 10-16) risk, respectively. DNA methylation alteration at cg17742416 [DNMT3A] is linked to both CD (P = 7.30 × 10-8) and UC (P = 1.04 × 10-4) risk, while cg03599224 [LTA/TNF] is associated with CD risk (P = 1.91 × 10-6), and cg14647125 [AHRR] and cg23916896 [AHRR] are linked to UC risk (P = 0.001 and 0.002, respectively). Our study identifies biological mechanisms and pathways involved in the effects of smoking on the pathogenesis of IBD.

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

INTRODUCTION

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

METHODS

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

RESULTS

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

DISCUSSION

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

Corticosteroids in inflammatory bowel disease: Are they still a therapeutic option?

Despite the development and incorporation of new therapeutic strategies, such as biologic therapy and small molecules, corticosteroids still play an important role in inducting inflammatory bowel diseases (IBD) remission. Variables like indicating the right doses at the right time, in adequate intervals, the security of these drugs and the pharmacological alternatives available must be considered by the providers when they are indicated to patients with IBD. Although the use of corticosteroids is considered as a marker of quality of care in patients with IBD, the use of these drugs in the clinical practice of IBD is far from being the correct one. This review article is not intended to be just a classic review of the indications for corticosteroids. Here we explain the scenarios in which, in our opinion, steroids would not be an appropriate option for our patients, as well as the most frequent mistakes we make in our daily practice when using them.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Real-world effectiveness and safety of ustekinumab and vedolizumab in elderly patients with Crohn's disease

Studies report favorable efficacy and safety profiles of ustekinumab (UST) and vedolizumab (VDZ) in Crohn's disease (CD), but effectiveness and safety data in elderly patients with CD is lacking. We retrospectively analyzed 78 elderly patients (39 each UST and VDZ) and found that patients on UST and VDZ experienced similar rates of clinical response, remission and mucosal healing despite high proportion of prior biologic exposure. Both UST and VDZ appear to be effective and safe in this at-risk CD population. Further large studies are needed to validate our findings.

Comparison of Disease Phenotype and Course among Elderly- and Early-Onset Inflammatory Bowel Diseases in the Middle East

BACKGROUND

It is unknown if the clinical manifestations and phenotype of disease are comparable between early- and elderly-onset inflammatory bowel disease (IBD). We aimed to seek differences in disease phenotype, course, complications, and treatment between early- and elderly-onset IBD patients.

METHODS

This retrospective cohort study on registered IBD patients in the Iranian Registry of Crohn's and Colitis (IRCC) compared demographics, disease phenotype, disease activity, IBD-related surgery and medications between early- and elderly-onset IBD. A generalized linear regression model was used to investigate the relative risk of age at diagnosis adjusted for gender and disease duration for the outcomes.

RESULTS

From 10048 IBD patients, 749 with early-onset (7.5%), and 472 (4.7%) elderly-onset IBD were enrolled: 855 (63.1%) ulcerative colitis (UC) and 366 (26.9%) Crohn's disease (CD). Left-sided colitis was more frequent among elderly-onset UC patients (P<0.001). Ileum and ileocolonic locations were the most common types in elderly-onset and early-onset CD patients, respectively. In comparison with elderly-onset UC, early-onset cases more often used prednisolone (22.1% vs. 11.4%, P=0.001), immunomodulators (44.9% vs 25.2%, P<0.001) and anti-tumor necrosis factors (TNF) (20.1% vs 11.9%, P=0.002). Elderly-onset UC patients had 0.7 times lower risk of aggressive phenotype (95%CI:0.6‒0.9, P=0.005). Early-onset CD was associated with higher use of prednisolone (27.7% vs 8.1%, P<0.001), immunomodulators (58.7% vs 41.8%, P=0.005) and anti-TNF (49.6% vs 35.4%, P=0.006).

CONCLUSION

Early-onset IBD was associated with a more aggressive phenotype and higher prednisolone, immunomodulators, and anti-TNF use.

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.

Inflammatory bowel disease in the elderly: A focus on disease characteristics and treatment patterns

Background

As the population ages, the number of elderly inflammatory bowel disease (IBD) patients is expected to increase. The clinical features and therapeutic options for young and old patients may differ, as elderly IBD patients are likely to have different comorbidities and disease characteristics. The goal of this study was to examine the clinical aspects and therapeutic choices for elderly Saudi IBD patients.

Methods

We conducted a retrospective study aimed at describing the demographic, clinical, and management characteristics of IBD in elderly patients (≥60 years) who followed up at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. The data was extracted from the KAUH inflammatory bowel disease information system (IBDIS) registry. The primary outcome was to describe disease characteristics in accordance with the Montréal classification and the secondary outcomes were to describe treatment patterns and identify significant clinical associations.

Results

Our data were collected from 76 patients who fulfilled the study inclusion criteria. Females outnumbered males (53.9% vs 46.1%) and the mean age was 51.5 ± 9.7 years. Essential hypertension (26.3%) was the most common comorbidity followed by diabetes mellitus (23.6%), and malignant neoplasms (9.21%). More than half of the patients with Crohn's disease (CD) had disease onset after forty years of age. The most common form of disease distribution was ileocolonic disease (64.7%). Less than 17% of patients had a penetrating disease phenotype. About 88 percent of patients with UC presented >40 years of age. Approximately, half of the cohort had left-sided ulcerative colitis (UC) (48%), followed by pancolitis (40%). The most prescribed medication class for IBD was 5-aminosalicylic acid (5-ASA) derivatives (56.58%) followed by corticosteroids and immunosuppressive drugs.

Conclusions

In Saudi Arabia, age-specific concerns including comorbidities and polypharmacy remain the major challenges in the management of elderly IBD patients.

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.

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.

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.

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.

Real-World Effectiveness and Safety of Ustekinumab in Elderly Crohn's Disease Patients

INTRODUCTION

The efficacy and safety profile of ustekinumab (UST) in Crohn's disease (CD) is favorable; however, data in elderly patients are lacking. We aimed to assess the safety and efficacy of UST in elderly CD.

METHODS

We performed a retrospective cohort study of CD patients classified as elderly (age ≥ 65 years at UST initiation) or nonelderly (<65 years) treated at a large, tertiary referral center. Outcomes assessed were clinical (measured by physician global assessment [PGA]) and steroid-free response, remission, adverse events, and postsurgical complications were compared by age category. Multivariable regression modeling and survival analysis was also performed.

RESULTS

In total, 117 patients (elderly n = 39, nonelderly n = 78) were included in the study. Elderly patients had predominantly moderate disease (87.2%), while nonelderly had a higher proportion of severe disease activity (44.9%) (p = 0.001), though no differences in baseline endoscopic activity, prior biologic use, or steroid or immunomodulator use at baseline existed (p > 0.05 all). While nearly 90% patients in both groups experienced clinical response to UST, compared to nonelderly, elderly patients were less likely to achieve complete clinical remission (28.2% vs. 52.6%, p = 0.01). On regression modeling, age was not associated with clinical outcomes (p > 0.05 all). Mucosal healing was achieved in 26% elderly and 30% nonelderly patients (p = 0.74). There were no significant differences in infusion reactions (2.6% vs. 6.4%, p = 0.77), infection (5.2% vs. 7.7%, p = 0.7), or postsurgical complications (p = 0.99) by age category.

CONCLUSION

UST is safe and effective in elderly CD. Although limited by sample size and retrospective design, such real-world data can inform biologic positioning in this IBD population.

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.

Is it time to include older adults in inflammatory bowel disease trials? A call for action

The therapeutic management of older patients with inflammatory bowel disease (IBD) is challenging, particularly because of the absence of evidence-based guidelines for these patients, who seem to frequently be excluded from clinical trials. In this systematic review we investigated the exclusion of older patients with IBD from phase 3 studies registered on PubMed and ClinicalTrials.gov, by assessing the upper limit of age exclusion criteria and the percentage of patients older than 65 years included in the trials. Exclusion criteria other than age were also recorded, and comorbidities were analysed separately. Our review of 222 phase 3 studies shows that older patients are frequently excluded from IBD clinical trials because of their age, which was used as an exclusion criterion in 129 (58%) of the 222 assessed trials. Of the 32 trials that detailed the percentage of included patients who were 65 years or older, only 763 (5·4%) patients of the 14 124 patients included were older than 65 years. In addition to age, patients were also excluded because of comorbidities (mainly renal, hepatic, and cardiovascular, and used as an exclusion criterion in 76% of trials), a history of dysplasia (45% of trials), and previous treatment for IBD (19% of trials). We propose a three-step process that should enable the inclusion of all older patients in IBD clinical trials, regardless of their age, comorbidities, and frailty.

The Role of Vitamin D in Immune System and Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a nonspecific inflammatory disease that includes ulcerative colitis (UC) and Crohn’s disease (CD). The pathogenesis of IBD is not fully understood but is most reported associated with immune dysregulation, dysbacteriosis, genetic susceptibility, and environmental risk factors. Vitamin D is an essential nutrient for the human body, and it not only regulates bone metabolism but also the immune system, the intestinal microbiota and barrier. Vitamin D insufficiency is common in IBD patients, and the abnormal low levels of vitamin D are highly correlated with disease activity, treatment response, and risk of relapse of IBD. Accumulating evidence supports the protective role of vitamin D in IBD through regulating the adaptive and innate immunity, maintaining the intestinal barrier and balancing the gut microbiota. This report aims to provide a broad overview of the role vitamin D in the immune system, especially in the pathogenesis and treatment of IBD, and its possible role in predicting relapse.

The elderly IBD patient in the modern era: changing paradigms in risk stratification and therapeutic management

The incidence and prevalence of inflammatory bowel disease (IBD) is rising in the elderly population. Compared with patients with onset during their 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 biological changes associated with aging including immunosenescence, dysbiosis, and frailty have a greater impact on disease outcomes. With the advent of an increasingly wider array of biologic and small-molecule therapeutic options, data regarding efficacy and safety of these agents in elderly IBD patients specifically are paramount, given the unique characteristics of this population.

Vedolizumab Is Safe in Elderly Veteran Patients With Inflammatory Bowel Disease

Many medications used to treat inflammatory bowel disease (IBD) can increase the risk of infection and cancer, particularly in elderly patients. This study found that vedolizumab, a targeted therapy, was effective and safe in elderly patients with IBD.

Use of thiopurines in inflammatory bowel disease: an update

Inflammatory bowel disease (IBD), once considered a disease of the Western hemisphere, has emerged as a global disease. As the disease prevalence is on a steady rise, management of IBD has come under the spotlight. 5-Aminosalicylates, corticosteroids, immunosuppressive agents and biologics are the backbone of treatment of IBD. With the advent of biologics and small molecules, the need for surgery and hospitalization has decreased. However, economic viability and acceptability is an important determinant of local prescription patterns. Nearly one-third of the patients in West receive biologics as the first/initial therapy. The scenario is different in developing countries where biologics are used only in a small proportion of patients with IBD. Increased risk of reactivation of tuberculosis and high cost of the therapy are limitations to their use. Thiopurines hence become critical for optimal management of patients with IBD in these regions. However, approximately one-third of patients are intolerant or develop adverse effects with their use. This has led to suboptimal use of thiopurines in clinical practice. This review article discusses the clinical aspects of thiopurine use in patients with IBD with the aim of optimizing their use to full therapeutic potential.

Cholinergic System and Its Therapeutic Importance in Inflammation and Autoimmunity

Neurological and immunological signals constitute an extensive regulatory network in our body that maintains physiology and homeostasis. The cholinergic system plays a significant role in neuroimmune communication, transmitting information regarding the peripheral immune status to the central nervous system (CNS) and vice versa. The cholinergic system includes the neurotransmitter\ molecule, acetylcholine (ACh), cholinergic receptors (AChRs), choline acetyltransferase (ChAT) enzyme, and acetylcholinesterase (AChE) enzyme. These molecules are involved in regulating immune response and playing a crucial role in maintaining homeostasis. Most innate and adaptive immune cells respond to neuronal inputs by releasing or expressing these molecules on their surfaces. Dysregulation of this neuroimmune communication may lead to several inflammatory and autoimmune diseases. Several agonists, antagonists, and inhibitors have been developed to target the cholinergic system to control inflammation in different tissues. This review discusses how various molecules of the neuronal and non-neuronal cholinergic system (NNCS) interact with the immune cells. What are the agonists and antagonists that alter the cholinergic system, and how are these molecules modulate inflammation and immunity. Understanding the various functions of pharmacological molecules could help in designing better strategies to control inflammation and autoimmunity.

Clinical Considerations Regarding the Use of Thiopurines in Older Patients with Inflammatory Bowel Disease

The number of older patients with inflammatory bowel disease (IBD) is increasing due to both improvements in the life expectancy of patients with long-lasting IBD and later onset of the disease. In spite of a less aggressive IBD phenotype, disease management in older patients is hampered by comorbidities and polypharmacy (which increase the risk of drug-related adverse events and errors in medication intake) and also by an increased risk of the infections and malignancies associated with the immunosuppressive drugs that are frequently used to treat IBD. Thiopurines are the most frequently used immunosuppressive drugs in IBD, though they are often discontinued due to adverse events. However, when tolerated, thiopurines are efficient in the maintenance of remission in ulcerative colitis and Crohn's disease. In fact, thiopurines still have a role to play in the treatment algorithm of older patients with IBD because anti-tumor necrosis factor agents do not provide clear advantages for this population in terms of their safety profile, while data on the new biological drugs are still scarce. In this article, we review the optimal use of thiopurines in older patients with IBD.

Inflammatory Bowel Disease in the Older Adult

Although management of inflammatory bowel disease follows a similar approach for all adults, there are certain characteristics making its treatment more challenging in older patients. The advent of novel medical treatments has changed the paradigm of inflammatory bowel disease, with an increasing focus on preventing disease progression in addition to controlling symptoms. The safety of these therapies in the elderly needs to be considered. Management of inflammatory bowel disease in the elderly is confounded by comorbidities that can increase the risk of medication or surgical complications; polypharmacy and altered pharmacokinetics also increase the risk of drug-drug interactions and adverse events.

Inflammatory Bowel Disease: A Nationwide Study of Hip Fracture and Mortality Risk After Hip Fracture

BACKGROUND AND AIMS

With rising rates of inflammatory bowel diseases [IBD] in older adults, management of comorbidities such as osteoporosis is becoming increasingly important. Hip fracture [HF] is the most serious consequence of low bone mineral quality and is associated with excess risk of mortality. For older IBD patients, there are only limited data available. Therefore, we aimed to assess the association of IBD with HF, and all-cause mortality risk after HF, among IBD patients older than 50 years.

METHODS

In a national database-registered case-control study, 56 821 HF cases aged ≥50 years, and 113 718 age-, sex- and region-matched non-hip-fracture controls, were analysed between 2012 and 2016. A history of IBD was assessed from data from Austrian social health insurance funds. Logistic regression and Cox proportional multivariate models were used to test the association of IBD with HF and post-hip fracture mortality risk.

RESULTS

A total of 531 patients were identified with IBD (25.0% men, mean age 81.2 years, standard deviation [SD] 9.7). Analysis, adjusted for anti-osteoporotic treatment, use of glucocorticoids, and selected medications, showed that IBD patients had an increased odds of HF (odds ratio [[OR] 2.22, 95% confidence interval [CI] 1.86-2.64). Patients with Crohn's disease [CD] revealed a higher HF odds in contrast to patients with ulcerative colitis [OR 2.91, 95% CI 2.17-3.89 and OR 1.89, 95% CI 1.52-2.35, respectively]. Overall mortality risk after HF was higher among female CD patients [HR 1.75, 95% CI 1.28-2.41] than in the general population.

CONCLUSIONS

IBD was strongly associated with HF in older patients. Post-hip fracture mortality risk was elevated particularly in women with CD.

Gastroenterologists' preference and risk perception on the use of immunomodulators and biological therapies in elderly patients with ulcerative colitis: an international survey

BACKGROUND AND AIMS

Comorbidities, polypharmacy, malignancies, and infections complicate management of elderly patients with inflammatory bowel diseases (IBD). This study assessed gastroenterologists' preference in the prescription of medications or surgery to elderly patients with IBD, and the factors associated with their choices.

METHODS

An international case-based survey was conducted that presented three cases of steroid-dependent ulcerative colitis assessing young-age versus elderly-age patients, with and without comorbidity. Physician characteristics and practice demographics were collected. Factors associated with selection of different choices of therapy were determined by logistic regression analysis.

RESULTS

A total of 424 respondents from 41 countries were included. Vedolizumab (53.2%) and thiopurines (19.4%) were the top treatment preferences for moderate-to-severe ulcerative colitis (P < 0.0001). Comorbidity and older age were independently associated with more frequent use of vedolizumab (P < 0.0001), and less frequent use of immunomodulators and anti-tumour necrosis factor (TNF; P < 0.0001). Comorbidity was the only independent predictor for selecting colectomy (P < 0.0001). A history of lymphoma (94%) and opportunistic infection (78.3%) were the most frequent conditions precluding the use of thiopurine and anti-TNF in elderly patients with IBD. Only 6.1% of respondents considered patient age a limit for vedolizumab, while 37.9% considered age as a limiting factor in prescribing thiopurines (P < 0.001). Geographical heterogeneity was identified with significantly more physicians from Oceania and North America favouring the use of vedolizumab.

CONCLUSION

Vedolizumab was the preferred first-line agent in the treatment of elderly patients with IBD with steroid-dependent moderate-to-severe ulcerative colitis. Older age and presence of comorbidity influenced the selection of medication. Comorbidity was the main predictor of colectomy. Geographical heterogeneity in prescribing habits may relate to medication reimbursement in individual countries.

Elderly-onset vs adult-onset ulcerative colitis: a different natural history?

Background

Incidence of ulcerative colitis (UC) in elderly population is increasing because of ageing and because of its minimal impact on life span. Data on natural history, outcomes and therapeutic strategies are limited.

Our aim is to characterize UC in elderly-onset patients followed at our Inflammatory Bowel Disease outpatient clinic and compare with adult-onset UC.

Methods

From January 2000 to June 2019, 94 patients with UC diagnosed after the age of 65 years (elderly group, E-O) were identified and matched 1–1 according to gender and calendar year of diagnosis with patients diagnosed with UC at age between 40 and 64 years (adult age, A-O).

Results

Comorbidity Index (3.8 vs 1.6, p < 0.0005) was higher for elderly UC patients. Symptoms at presentation were similar between the two groups, although abdominal pain was more common in adults, and weight loss was more common in the elderly. At diagnosis, left colitis (61% vs 39%) and proctitis (14% vs 26%) (p = 0.011) were more frequent in the elderly. Therapy and clinical behaviour were similar. Surgery was more frequently performed in the elderly (20% vs 9%, p = 0.02), while biological therapy was less used (2.1% vs 22%, p < 0.0005). Complications were more frequent in the elderly. Extraintestinal manifestations were lower in elderly patients (9.6% vs 19.2%, p = 0.061). Time to first relapse was similar between the two groups. Mortality (p < 0.0005) was higher in elderly patients.

Conclusions

Ulcerative Colitis has similar presentation and behaviour in elderly and adults patients. However, the elderly are more fragile because of comorbidities, increased risk of infections and disease-related complications.

Steroid use and misuse: a key performance indicator in the management of IBD

Corticosteroids remain an important tool for inducing remission in inflammatory bowel disease (IBD) but they have no role in maintenance of remission. The significant adverse side effect profile of these drugs means their use should be avoided where possible or measures taken to reduce their risk. Despite an expanding array of alternative therapies, corticosteroid dependency and excess remain common. Appropriate steroid use is now regarded a key performance indicator in the management of IBD. This article aims to outline indications for corticosteroid use in IBD, their risks and strategies to reduce their use and misuse.

Analysis of risk factors and outcome in peritoneal dialysis patients with early-onset peritonitis: a multicentre, retrospective cohort study

OBJECTIVES

To investigate the risk factors associated with early-onset peritonitis (EOP) and their influence on patients' technique survival and mortality.

STUDY DESIGN

Retrospective, cohort study.

SETTING

Three peritoneal dialysis (PD) units in Shanghai.

PARTICIPANTS

PD patients from 1 June 2006 to 1 May 2018 were recruited and followed up until 31 December 2018. According to time-to-first episode of peritonitis, patients were divided into non-peritonitis (n=144), EOP (≤6 months, n=74) and late-onset peritonitis (LOP) (>6 months, n=139).

PRIMARY AND SECONDARY OUTCOME MEASURES

EOP was defined as the first episode of peritonitis occurring within 6 months after the initiation of PD. The outcomes were all-cause mortality and technique failure.

RESULTS

Of the 357 patients, 74 (20.7%) patients developed their first episode of peritonitis within the first 6 months. Compared with the LOP group, the EOP group had older ages, more female patients, higher Charlson Comorbidity Index (CCI) score, lower serum albumin levels and renal function at the time of initiation of PD, and higher diabetes mellitus and peritonitis rates (p<0.05). Staphylococcus was the most common Gram-positive organism in both EOP and LOP groups. The multivariate logistic regression analysis showed that factors associated with EOP included a higher CCI score (OR 1.285, p=0.011), lower serum albumin level (OR 0.924, p=0.016) and lower Kt/V (OR 0.600, p=0.018) at start of PD. In the Cox proportional-hazards model, EOP was more likely a predictor of technique failure (HR 1.801, p=0.051). There was no difference between EOP and LOP for all-cause mortality.

CONCLUSION

A higher CCI score and lower serum albumin level and Kt/V at PD initiation were significantly associated with EOP. EOP also predicted a high peritonitis rate and poor clinical outcome.

Risk of Infection and Types of Infection Among Elderly Patients With Inflammatory Bowel Disease: A Retrospective Database Analysis

BACKGROUND

Inflammatory bowel disease (IBD) treatment in the elderly is challenging in part because of increased risk of infections. The aim of our study was to determine the absolute and relative risk of infections among the elderly IBD patient population and to identify factors affecting the risk of infections in the overall IBD patient population.

METHODS

A retrospective study of patients with IBD initiating corticosteroids, immunomodulators (IM), or biologic therapy (January 2010-December 2014) was conducted using the Truven Market Scan database. IM and biologic exposure were assessed in a time-dependent manner. ICD-9 codes identified infection during follow-up. A Cox proportional hazards model was fitted to gauge the association between age, other covariates, and infection risk.

RESULTS

We identified 63,759 patients with IBD. We found 2664 infections (incidence rate [IR] = 16.95/100 person-years) among 8788 elderly patients with IBD and 10,515 (IR = 10.49/100 person-years) among the nonelderly group. Pneumonia (39.8%), sepsis (13.2%), and candidiasis (12.9%) were the most common infections in the elderly. Factors associated with a higher risk of infection included being elderly (HR: 1.27, P < 0.0001), anti-TNF therapy (HR: 1.64, P < 0.0001), IM therapy (HR: 1.32, P < 0.0001), and polypharmacy (HR: 1.32, P < 0.0001).

CONCLUSIONS

Advanced age, anti-TNF (biologic) therapy, and IM therapy were associated with an increased risk of infection. Pneumonia was the most common infection among the elderly IBD population. Physicians should be mindful of these risks when prescribing medications for elderly patients with IBD, and ensure their patients are adequately vaccinated.

Treatment of Medicare Patients with Moderate-to-Severe Psoriasis who Cannot Afford Biologics or Apremilast

Elderly patients are a group with a high frequency of psoriasis. Their disease burden has negative impacts on their quality of life. While there is a clear need to treat these patients, there are challenges in doing so. This work seeks to define the challenges that exist in treating elderly Medicare patients, as well as to provide treatment suggestions for providers to follow if they encounter one or more of these challenges. Providers face the following challenges when creating treatment plants for elderly patients with psoriasis: difficulty in obtaining drug coverage through Medicare, increased medical comorbidities, and polypharmacy. Providers aim for regimens that are affordable, safe, and efficacious, but it is not always clear how to achieve this combination, especially in elderly Medicare patients. This work is relevant in that it aims to explain the logistical roadblocks posed by Medicare coverage and provide solutions for commonly encountered issues in the treatment of a disabling and common disease in a high-risk population. Specifically, alternative treatment options to biologics and small-molecule inhibitors are discussed and include topical therapies, phototherapy, methotrexate, acitretin, and cyclosporine and for psoriatic arthritis include corticosteroids and leflunomide. The specific risks and benefits of these therapies in the elderly population are provided, allowing providers to make patient-specific decisions about optimal regimens.

Variation in care of patients with elderly-onset inflammatory bowel disease in Ontario, Canada: A population-based cohort study

Background

Variation in health care, when not based on patient preference, may result in poorer care. We determined whether variation in health services utilization, gastroenterologist care and outcomes existed among patients with elderly-onset inflammatory bowel disease (IBD).

Methods

Patients with IBD (diagnosed ≥65 years) were identified from population-based health administrative data from Ontario, Canada (1999 to 2014). We assessed variation across multispecialty physician networks in gastroenterologist care and outcomes using multilevel logistic regression. Median odds ratios (MOR) described variation. We evaluated the association between gastroenterologist supply, specialist care and outcomes.

Results

In 4806 patients, there was significant variation in having ever seen a gastroenterologist (MOR 3.35, P < 0.0001), having a gastroenterologist as the primary IBD care provider (MOR 4.16, P < 0.0001), 5-year colectomy risk in ulcerative colitis (MOR 1.38, P = 0.01), immunomodulator use (MOR 1.47, P = 0.001), and corticosteroid use (MOR 1.26, P = 0.006). No variation in emergency department visits, hospitalizations or intestinal resection (Crohn’s) was noted. Patients in networks with fewer gastroenterologists were less likely to see a gastroenterologist (odds ratio [OR] 0.29, 95% confidence interval [CI] 0.15 to 0.56), have a gastroenterologist as their primary care provider (OR 0.27, 95% CI 0.12 to 0.59), be hospitalized within 5 years (OR 0.82, 95% CI 0.69 to 0.98), and be prescribed biologics within 1 year (OR 0.50, 95% CI 0.28 to 0.89).

Conclusions

Utilization of gastroenterology care in patients with elderly-onset IBD varies greatly. Patients treated by gastroenterologists and in networks with more gastroenterologists have better outcomes. There is a need to ensure all individuals with IBD have equal access to and utilization of specialist care to ensure the best possible outcomes.

IBD in the Elderly: Management Challenges and Therapeutic Considerations

PURPOSE OF REVIEW

Elderly patients with inflammatory bowel disease (IBD) are increasing in prevalence as our population ages and the incidence of IBD increases. The purpose of this review is to describe the management challenges in elderly IBD patients, including comorbid conditions and therapeutic considerations unique to the elderly population.

RECENT FINDINGS

The elderly experience coexisting comorbidities that complicate IBD management. The disease course and potential side effects of treatments can impact the elderly IBD patient differently than younger IBD patients. The duration for colorectal cancer surveillance (CRC) also remains controversial and should be individualized to determine when discontinuation is appropriate. Given greater safety considerations in the elderly IBD population, treatment targets and management goals require a more personalized approach in the elderly, taking into account coexisting comorbidities, inflammatory burden, and functional limitations.

Special Considerations for Colorectal Surgery in the Elderly IBD Patient

PURPOSE OF REVIEW

We sought to understand the key aspects to optimize in the perioperative period when treating an elderly surgical patient with inflammatory bowel disease.

RECENT FINDINGS

Addressing preoperative polypharmacy, frailty, and nutrition is important in the elderly population. Understanding intraoperative principles of oncologic risk and pouch formation and the advantages of laparoscopy are key. Postoperative-enhanced recovery pathways and VTE prophylaxis are essential for high-quality care. Preoperative, perioperative, and postoperative factors can greatly impact elderly patients' surgical outcomes.

How to manage IBD in the 'elderly'

As the incidence of inflammatory bowel disease (IBD) rises and the global population ages, the number of older people living with these conditions will inevitably increase. The challenges posed by comorbid conditions, polypharmacy, the unintended consequences of long-term treatment and the real but often underestimated mismatch between chronological and biological ages underpin management. Significantly, there may be differences in disease characteristics, presentation and management of an older patient with IBD, together with other unique challenges. Importantly, clinical trials often exclude older patients, so treatment decisions are frequently pragmatic, extrapolated from a number of sources of evidence and perhaps primarily dictated by concerns around adverse effects. This review aimed to discuss the epidemiology, clinical features and considerations with management in older patients with IBD.

IBD prevalence in Lothian, Scotland, derived by capture-recapture methodology

OBJECTIVE

IBD prevalence is estimated to be rising, but no detailed, recent UK data are available. The last reported prevalence estimate in the UK was 0.40% in 2003. We aimed to establish the current, and project future, prevalence in Lothian, Scotland.

DESIGN

We conducted an all-age multiparameter search strategy using inpatient IBD international classification of disease (ICD-10) coding (K50/51)(1997-2018), IBD pathology coding (1990-2018), primary and secondary care prescribing data (2009-2018) and a paediatric registry, (1997-2018) to identify 'possible' IBD cases up to 31/08/2018. Diagnoses were manually confirmed through electronic health record review as per Lennard-Jones/Porto criteria. Autoregressive integrated moving average (ARIMA) regression was applied to forecast prevalence to 01/08/2028.

RESULTS

In total, 24 601 possible IBD cases were identified of which 10 499 were true positives. The point prevalence for IBD in Lothian on 31/08/2018 was 784/100 000 (UC 432/100 000, Crohn's disease 284/100 000 and IBD unclassified (IBDU) 68/100 000). Capture-recapture methods identified an additional 427 'missed' cases (95% CI 383 to 477) resulting in a 'true' prevalence of 832/100 000 (95% CI 827 to 837).Prevalence increased by 4.3% per year between 2008 and 2018 (95% CI +3.7 to +4.9%, p<0.0001). ARIMA modelling projected a point prevalence on 01/08/2028 of 1.02% (95% CI 0.97% to 1.07%) that will affect an estimated 1.53% (95% CI 1.37% to 1.69%) of those >80 years of age.

CONCLUSIONS

We report a rigorously validated IBD cohort with all-age point prevalence on 31/08/2018 of 1 in 125, one of the highest worldwide.

Late-onset Crohn's disease: a comparison of disease behaviour and therapy with younger adult patients: the Italian Group for the Study of Inflammatory Bowel Disease 'AGED' study

BACKGROUND

Disease phenotype and outcome of late-onset Crohn's disease are still poorly defined.

METHODS

In this Italian nationwide multicentre retrospective study, patients diagnosed ≥65 years (late-onset) were compared with young adult-onset with 16-39 years and adult-onset Crohn's disease 40-64 years. Data were collected for 3 years following diagnosis.

RESULTS

A total of 631 patients (late-onset 153, adult-onset 161, young adult-onset 317) were included. Colonic disease was more frequent in late-onset (P < 0005), stenosing behaviour was more frequent than in adult-onset (P < 0003), but fistulising disease was uncommon. Surgery rates were not different between the three age groups. Systemic steroids were prescribed more frequently in young adult-onset in the first year, but low bioavailability steroids were used more frequently in late-onset in the first 2 years after diagnosis (P < 0.036, P < 0.041, respectively). The use of immunomodulators and anti-TNF's even in patients with more complicated disease, that is, B2 or B3 behaviour (Montreal classification), remained significantly inferior (P < 0.0001) in late-onset compared to young adult-onset. Age at diagnosis, Charlson comorbidity index, and steroid used in the first year were negatively associated with the use of immunomodulators and biologics. Comorbidities, related medications and hospitalizations were more frequent in late-onset. Polypharmacy was present in 56% of elderly Crohn's disease patients.

CONCLUSION

Thirty-two percent of late-onset Crohn's disease presented with complicated disease behaviour. Despite a comparable use of steroids and surgery, immunomodulators and biologics were used in a small number of patients.

Polypharmacy is a risk factor for disease flare in adult patients with ulcerative colitis: a retrospective cohort study

Background/Aims

Polypharmacy is a common clinical problem with chronic diseases that can be associated with adverse patient outcomes. The present study aimed to determine the prevalence and patient-specific characteristics associated with polypharmacy in an ulcerative colitis (UC) population and to assess the impact of polypharmacy on disease outcomes.

Methods

A retrospective chart review of patients with UC who visited a tertiary medical center outpatient clinic between 2006 and 2011 was performed. Polypharmacy was defined as major ( ≥ 5 non-UC medications) or minor (2–4 non-UC medications). UC medications were excluded in the polypharmacy grouping to minimize the confounding between disease severity and polypharmacy. Outcomes of interest include disease flare, therapy escalation, UC-related hospitalization, and surgery within 5 years of the initial visit.

Results

A total of 457 patients with UC were eligible for baseline analysis. Major polypharmacy was identified in 29.8% of patients, and minor polypharmacy was identified in 40.9% of the population. Polypharmacy at baseline was associated with advanced age (P< 0.001), female sex (P= 0.019), functional gastrointestinal (GI) disorders (P< 0.001), and psychiatric disease (P< 0.001). Over 5 years of follow-up, 265 patients remained eligible for analysis. After adjusting for age, sex, functional GI disorders, and psychiatric disease, major polypharmacy was found to be significantly associated with an increased risk of disease flare (odds ratio, 4.00; 95% confidence interval, 1.66–9.62). However, major polypharmacy was not associated with the risk of therapy escalation, hospitalization, or surgery.

Conclusions

Polypharmacy from non-inflammatory bowel disease medications was present in a substantial proportion of adult patients with UC and was associated with an increased risk of disease flare.

Elderly patients with inflammatory bowel disease: Updated review of the therapeutic landscape

High-quality data remains scarce in terms of optimal management strategies in the elderly inflammatory bowel disease (IBD) population. Indeed, available trials have been mostly retrospective, of small sample size, likely owing to under-representation of such a population in the major randomized controlled trials. However, in the last five years, there has been a steady increase in the number of published trials, helping clarify the estimated benefits and toxicity of the existing IBD armamentarium. In the Everhov trial, prescription strategies were recorded over an average follow-up of 4.2 years. A minority of elderly IBD patients (1%-3%) were treated with biologics within the five years following diagnosis, whilst almost a quarter of these patients were receiving corticosteroid therapy at year five of follow-up, despite its multiple toxicities. The low use of biologic agents in real-life settings likely stems from limited data suggesting lower efficacy and higher toxicity. This minireview will aim to highlight current outcome measurements as it portends the elderly IBD patient, as well as summarize the available therapeutic strategies in view of a growing body of evidence.

Safety of Biologic Therapy in Older Patients With Immune-Mediated Diseases: A Systematic Review and Meta-analysis

BACKGROUND & AIMS

Management of immune-mediated inflammatory diseases often requires lifelong immunosuppression. Increasing numbers of older patients have inflammatory diseases and are particularly vulnerable to risks of immune suppressive therapies-particularly infections and malignancies.

METHODS

We systematically searched PubMed/Medline and Embase to identify eligible studies that examined the safety of biologic therapies in older patients with immune-mediated inflammatory diseases (inflammatory bowel disease, rheumatoid arthritis, psoriasis). Included studies provided information on patients who began receiving therapy with a biologic agent when they were older than 60 years and a control population (either younger users of biologics or older patients who did not use biologics). Information of on overall pooled rates of infections, malignancy, and mortality were extracted. A DerSimonian and Laird random effects model was used to calculate pooled odds ratios (ORs) and 95% CIs.

RESULTS

Our meta-analysis included 14 unique studies that comprised 4719 older users of biologics, 13,305 younger users of biologics, and 3961 older patients who did not use biologics. The pooled prevalence of infections in older and younger users of biologics was 13% and 6% respectively, yielding a pooled random effects odds ratio of 2.28 (95% CI, 1.57-3.31). Older age was associated with a significant increase in risk of malignancy (OR, 3.07; 95% CI, 1.98-4.62) compared to younger age. Older users of biologics had a 3-fold increase in risk of infection compared to patients who did not use biologics (OR, 3.60; 95% CI, 1.62-8.01), but there were no significant differences in odds of malignancy (0.54, 95% CI, 0.28-1.05) or death (OR, 1.52; 95% CI, 0.44-5.28) compared to older patients who did not use biologics.

CONCLUSION

In a systematic review and meta-analysis of studies on the safety of biologic therapies in older patients with inflammatory diseases, we found that older users of biologic agents have an increased risk of infections compared with younger users or older patients who do not use biologics. Large, prospective cohort studies are needed to examine safety of biologic therapy in older patients with immune-mediated diseases.
