Post-operative complications in elderly onset inflammatory bowel disease: a population-based study

Considerations on Multimorbidity and Frailty in Inflammatory Bowel Diseases

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

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Role of Age as a Predictor of Major Complications After Elective Surgery for Ulcerative Colitis

BACKGROUND

The incidence of ulcerative colitis (UC) in the elderly population is increasing. The aim of this study was to assess the degree to which age and other factors increase the risk of developing major complications in patients undergoing elective surgery for UC.

METHODS

Using the ACS-NSQIP database from 2016 to 2020, patients undergoing elective surgery for UC were divided into four categories: younger than 30, 30-49, 50-69, and 70 or older. A composite outcome was created including major complications and multivariable analysis was performed to identify factors associated with composite major complications.

RESULTS

5946 patients diagnosed with ulcerative colitis who underwent elective surgery were included in the analysis. 14.1% of all patients developed a major complication. For patients with UC, factors associated with the development of a major complication were age 50-69 (OR 1.31, P = .034), male sex (OR 1.38, P < .001), Black race (OR 1.47, P = .049), dependent status (OR 2.06, P = .028), hypoalbuminemia (OR 1.92, P < .001), preoperative steroid treatment (OR 1.27, P = .038), preoperative transfusion (OR 1.91, P < .001), open surgical approach (OR 1.44, P = .002), and partial colectomy (OR 1.51, P = .007). Specifically in patients aged 70 or older, hypoalbuminemia (OR 3.20, P < .001) and preoperative transfusion (OR 2.78, P = .019) were associated with a major complication.

CONCLUSION

Age is a risk factor for the development of a major complication in UC patients undergoing elective surgery. However, it is not the only risk factor nor is it the one that increases the risk the most.

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.

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.

Burden and Trends of IBD in 5 Asian Countries From 1990 to 2019: A Comparison With the United States and the United Kingdom

BACKGROUND

IBD is becoming a global health challenge, with substantial variations in incidence and death rates between Eastern and Western countries.

OBJECTIVE

This study aimed to investigate the burden and trends of IBD in 5 Asian countries, the United States, and the United Kingdom.

DESIGN

This was a cross-sectional study.

SETTING

Data were obtained from Global Burden of Disease 2019 Study.

PATIENTS

Patients with IBD were included.

MAIN OUTCOME MEASURES

Incidence, death, and age-standardized rates of IBD were measured.

RESULTS

The age-standardized incidence and rates of death from IBD gradually decreased worldwide from 1990 to 2019. The age-standardized incidence rate in the United States decreased from 1990 to 2000 and then increased gradually from 2000 to 2019; the age-standardized incidence rates in the United Kingdom, Mongolia, and China increased gradually from 1990 to 2019, whereas in the Democratic People's Republic of Korea, it decreased from 1990 to 1995 and increased gradually from 1995 to 2019. The age-standardized death rate in the Republic of Korea exhibited a rising trend until 1995, fell significantly up to 2015, and then stabilized from 2015 to 2019. The age-standardized death rate in the United States showed a rising trend until 2007, and then decreased gradually from 2007 to 2019, whereas the rate in the United Kingdom showed a rising trend until 2010 and decreased from 2010 to 2019. The age-standardized death rates in China, Mongolia, the Democratic People's Republic of Korea, and Japan decreased gradually from 1990 to 2019. The age-standardized incidence and death rates in the United States and United Kingdom in recent decades were higher than those in the 5 Asian countries. The peak age-standardized incidence rates in the 7 countries were among people of 20 to 60 years of age. The age-standardized death rates in all 7 countries exhibited rising trends with increasing age, with older individuals, particularly those aged ≥70 years, accounting for the most deaths.

LIMITATIONS

Limitations of this study include data from different countries with different quality and accuracy.

CONCLUSIONS

There have been large variations in the burdens and trends of IBD between 5 Asian countries, the United States, and the United Kingdom during the past 3 decades. These findings may help policymakers to make better public decisions and allocate appropriate resources. See Video Abstract at http://links.lww.com/DCR/B996 .

Frailty is a stronger predictor than age for postoperative morbidity in Crohn's disease

BACKGROUND

Patients with Crohn's disease are particularly susceptible to preoperative frailty owing to the chronic nature of the illness and immunosuppressive therapy. The hypothesis in this study was that frailty would have a greater impact on postoperative outcome than age in older individuals with Crohn's disease.

METHODS

Data were obtained from the National Surgical Quality Improvement Program from the years 2012 to 2018. Patients with Crohn's disease who underwent a bowel resection were identified from diagnostic and procedure codes. Frailty was assessed using the 5-point Simplified Frailty Index (0-not frail, 5-most frail). Age was defined as an ordinal variable with 3 age ranges (18-64, 65-79, >80 years). Aggregate morbidity was classified according to the standard National Surgical Quality Improvement Program definitions. Simplified Frailty Index was evaluated as a potential predictor of morbidity and mortality using covariate-adjusted logistic regression modeling.

RESULTS

A total of 9,023 patients underwent bowel resection for Crohn's disease during the study period. Patient Simplified Frailty Index ranged from 0 to 3 (Simplified Frailty Index = 0, 82%; 1, 15%; 2, 2.5%; 3, 0.1%), and higher Simplified Frailty Index was associated with increased age (P < .01). In multivariate regression, Simplified Frailty Index was significantly associated with postoperative morbidity (Simplified Frailty Index ≥ 2: odds ratio = 2.59, 95% confidence interval [1.84-3.63], P < .0001). In contrast, age was not found to be a significant predictor of morbidity when adjusted for Simplified Frailty Index and other covariates (P > .05).

CONCLUSION

Frailty is a stronger predictor than age for morbidity in Crohn's-related bowel resection. Functional assessments and vulnerability screening should be used to determine surgical candidacy rather than age alone.

Progression of Elderly Onset Inflammatory Bowel Diseases: A Systematic Review and Meta-Analysis of Population-Based Cohort Studies

BACKGROUND & AIMS

The incidence of inflammatory bowel diseases (IBDs) in older adults is increasing. We performed a systematic review and meta-analysis to evaluate progression of elderly onset (EO) IBD in population-based cohorts and compared it with adult onset (AO) IBD.

METHODS

In a systematic review through June 1, 2019, we identified population-based cohort studies of EO IBD reporting the cumulative risk of hospitalization, surgery, mortality, treatment patterns, escalation, and/or malignancy. Data were synthesized using random-effects meta-analysis as cumulative risk of events at 1 year, 5 years, and 10 years, and compared with data from patients with AO IBD in the same cohorts.

RESULTS

We identified 9 studies, comprising 14,765 patients with EO IBD. In patients with EO Crohn's disease (CD), the cumulative 5-year risk of surgery was 22.6% (95% CI, 18.7-27.2) and was similar to that of patients with AO CD (relative risk [RR], 1.04; 95% CI, 0.80-1.34). Overall exposure to corticosteroids was comparable between patients with EO CD vs AO CD (5-year risk: 55.4%; 95% CI, 53.4-57.4; RR, 0.88; 95% CI, 0.78-1.00), but exposure to immunomodulators (31.5%; 95% CI, 29.7-33.4; RR, 0.62; 95% CI, 0.51-0.77) or biologic agents (6.5%; 95% CI, 5.6-7.6; RR, 0.36; 95% CI, 0.25-0.52) was significantly lower for patients with EO CD than for patients with AO CD. Similarly, in patients with EO ulcerative colitis (UC), the cumulative 5-year risk of surgery was 7.8% (95% CI, 5.0-12.0), similar to the risk for patients with AO UC (RR, 1.29; 95% CI, 0.79-2.11). Overall exposure to corticosteroids was comparable between patients with EO UC vs AO UC (5-year risk: 57.2%; 95% CI, 55.6-58.7; RR, 0.98; 95% CI, 0.91-1.06), but exposure to immunomodulators (16.1%; 95% CI, 15.0-17.2; RR, 0.58; 95% CI, 0.54-0.62) or biologic agents (2.0%; 95% CI, 1.6-2.5; RR, 0.36; 95% CI, 0.24-0.52) was significantly lower for patients with EO UC than for patients with AO UC. Patients with EO IBD appeared to have increased mortality, but not malignancy, compared with the general population. There were few data on comorbidities or adverse effects of medications.

CONCLUSIONS

In a systematic review and meta-analysis, we found that patients with EO IBD have a similar risk of surgery as patients with AO IBD. However, patients with EO IBD are less likely to receive treatment with immunomodulators or biologic agents.

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.

Crohn's disease and ulcerative colitis are associated with different lipid profile disorders: a nationwide population-based study

BACKGROUND

The relationships between lipid profiles and IBD remain elusive.

AIM

To determine the association of IBD with serum lipid profiles.

METHODS

A nationwide population-based study was performed using claims data from the Korean National Healthcare Insurance service. A total of 9 706 026 subjects undergoing medical check-ups in 2009 were enrolled and followed up until 2016. Individuals who developed Crohn's disease (CD) or ulcerative colitis (UC) were identified during follow-up. Adjusted hazard ratio (aHR) by age, sex, body mass index, cigarette smoking, alcohol drinking, exercise, income and underlying comorbidities was calculated to define the impact of serum lipid profiles on developing IBD.

RESULTS

During a median follow-up of 7.3 years, IBD was detected in 7,058 (0.07%) individuals. Compared with the highest quartile of serum total cholesterol (TC) levels, lower TC levels were associated with higher incidence of CD (aHR: Q1, 2.52; Q2, 1.52; Q3, 1.27), but not UC. Lower serum LDL-C levels were associated with higher incidence of CD (aHR: Q1, 1.92; Q2, 1.47; Q3, 1.22), but not UC. Moreover, lower serum HDL-C levels were associated with higher incidence of CD (aHR: Q1, 2.49; Q2, 1.90; Q3, 1.43), but not UC. In contrast, lower serum triglyceride levels were associated with higher incidence of UC (aHR: Q1, 1.22; Q2, 1.19; Q3, 1.19), but not CD.

CONCLUSIONS

Low serum TC, LDL-C and HDL-C levels were associated with CD. Low serum triglyceride levels were related to UC.
