Comorbidity and polypharmacy, more prevalent among older persons, may impact the treatment of patients with inflammatory bowel disease (IBD). The aims of this study were to assess the frequency of polypharmacy and medication interactions within a cohort of older patients with IBD and describe IBD treatment patterns.MethodsCohort study of 190 patients with IBD 65 years or older followed at a tertiary IBD referral center from 2006 to 2012. Data collected included demographics, IBD-specific characteristics including disease activity, and comorbidity. Medication histories were extracted from medical records, and data were used to classify polypharmacy, frequency, and severity of potential medication interactions and inappropriate medication use.ResultsOlder patients with IBD were prescribed an average of 9 routine medications. Severe polypharmacy (≥10 routine medications) was present in 43.2% of studied patients and associated with increasing age, greater comorbidity, and steroid use. Overall, 73.7% of patients had at least 1 potential medication interaction, including 40% of patients with potential IBD medication-associated interactions. Chronic steroids were prescribed to 40% of the older patients including 24% who were in remission or with mild disease activity. Only 39.5% of patients were on immunomodulators and 21.1% on biologics. Approximately, 35% of patients were given at least 1 Beers inappropriate medication and almost 10% were receiving chronic narcotics.ConclusionsOlder patients with IBD are at increased risk for severe polypharmacy and potential major medication interactions especially with increasing comorbidity and chronic steroid use. Steroid-maintenance therapies are prevalent among the older patients with IBD with lower utilization of steroid-sparing regimens.

Key Points Ageing is associated with immunodeficiency relative to younger people, which is termed 'inflamm-ageing' and might affect the natural history of IBD in the elderly Pharmacokinetic changes associated with ageing might affect drug metabolism, dosing schedules and response to IBD therapies Comorbidities, with associated polypharmacy, are prevalent among elderly patients with IBD and interactions between different medications can increase the likelihood of adverse effects Thiopurines and anti-TNF agents are under prescribed among older patients with IBD, with a tendency towards sustained corticosteroid and mesalazine use, even among patients with moderate-to-severe disease or steroid dependency The therapeutic efficacy of immunomodulators and biologic agents in older patients might not reflect the response rates reported in clinical trials, as adverse effect profiles can limit sustained use Further investigation of the natural history and response to therapy within the older IBD cohort is essential, as the complexities associated with ageing might compete with optimizing IBD care Factors associated with ageing, such as comorbidities, polypharmacy and diminished physical reserve, can affect the natural history of IBD. This Review highlights how these age-associated variables can affect older patients with IBD and also illustrates the multiple gaps in our current knowledge of IBD in the elderly. As the global population ages, the number of older people (≥65 years) living with IBD is expected to increase. IBD therapeutics have advanced considerably over the past few decades with the introduction of multiple steroid-sparing agents as well as numerous clinical trials that have tested new therapeutic targets. However, the current paradigms for IBD management might not be directly translatable to older patients with IBD. Age-related factors such as immunodeficiency relative to younger patients, comorbidity, polypharmacy and diminished physical reserve directly or indirectly affect the natural history of their disease. This Review highlights how these age-associated variables can affect older patients with IBD and also illustrates the multiple gaps in our current knowledge of IBD in the elderly.

On February 9, 2016, the Food and Drug Administration Arthritis Advisory Committee recommended by a vote of 21 to 3, that the biosimilar to infliximab, CT-P13, be approved for rheumatoid arthritis and ankylosing spondylitis and, by extrapolation, for all the indications for which infliximab is currently approved, including adult and pediatric ulcerative colitis and Crohn's disease. On April 5, 2016, the Food and Drug Administration concurred with this recommendation and approved CT-P13 (Inflectra; Pfizer Inc.) for all diseases for which infliximab had previously been approved, including adult and pediatric moderate to severe ulcerative colitis and pediatric and adult moderate to severe and fistulizing Crohn's disease. This was despite the absence of any randomized controlled trials studying the infliximab biosimilar in any inflammatory bowel disease. This highly controversial approach has been criticized by various rheumatology and gastroenterology professional societies around the world. This review will cover the stepwise approach to biosimilar development, issues of extrapolation and interchangeability, and conclude with a discussion of the regulatory, intellectual property issues, and financial implications, which will all intersect in the decision and ability to prescribe a biosimilar or reference anti–tumor necrosis factor drug.

Background:Patients with inflammatory bowel disease (IBD) are at increased risk of infections, bone fractures, and skin cancers.Objective:We developed preventive health videos using a patient-centered approach and tested their impact on preventive health uptake.Methods:Five animated videos explaining preventive health recommendations in IBD were iteratively developed with patient-centered focus groups and interviews. A randomized controlled trial was then conducted in a web-based IBD cohort to test the impact of video- versus text-based educational interventions. The primary outcome was receipt of the influenza vaccine. Secondary outcomes included intention to receive other preventive health services.Results:Five animated videos were developed with patient input. A total of 1056 patients with IBD were then randomized to receive the video (n=511) or text-only (n=545) interventions; 55% (281/511) of the video group and 57% (311/545) of the text-only group had received their influenza vaccine in the prior year. Immediately after the intervention, 73% (502/683) of patients reported their intention to receive the vaccine, with no difference by the type of intervention (75%, 231/307, for the video group and 72%, 271/376, for the text-only group). The proportion of patients who actually received the influenza vaccine after the intervention also did not differ by messaging type (P=.07). The strongest predictor of both intention to receive and actual receipt of the influenza vaccine was prior influenza vaccination. Older age was also associated with a higher likelihood of the intention to receive (age 36-75 years relative to 18-35 years; P=.006) and actual receipt (age >75 years relative to 18-35 years; P=.05) of the influenza vaccine.Conclusions:The proportion of patients receiving the influenza vaccine was high in both groups, but there was no difference in receipt of or in the intention to receive preventive health recommendations by type of messaging. Notably, a portion of patients in both groups had intended to be vaccinated but did not ultimately receive the vaccine. Further evaluation of patient-education strategies is warranted to improve preventive health uptake among patients with IBD.Trial Registration:ClinicalTrials.gov NCT05997537; https://clinicaltrials.gov/ct2/show/NCT05997537

Background and AimsInfliximab rescue therapy is effective in patients with corticosteroid refractory acute severe ulcerative colitis, but predictors of response remain poorly understood. We aimed to identify predictors of colectomy in this high-risk patient population.MethodsPatients hospitalized with acute severe ulcerative colitis who received infliximab after failing intravenous corticosteroid therapy between July 2012 and June 2017 were retrospectively identified. Stepwise regression with backward elimination was used to identify predictors of colectomy at 90 days and 1 year. Ninety-day and 1-year colectomy rates were compared between the patients who received 5 mg/kg and 10 mg/kg IFX rescue dose.ResultsSixty-three patients met the eligibility criteria. Twenty-nine patients received 5 mg/kg, and 34 received 10 mg/kg infliximab dose. Serum albumin on admission (OR 0.10; p = 0.04) and band neutrophil percentage at the time of infliximab administration (OR 1.21; p = 0.02) were independent predictors of 90-day colectomy. A combination of serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy. Unadjusted 90-day and 1-year colectomy rates were similar in the 5 mg/kg and 10 mg/kg infliximab groups. After adjusting for confounding factors, 10 mg/kg infliximab dose was potentially protective for 90-day (OR 0.07; p = 0.06) but not for 1-year colectomy (OR 0.19; p = 0.16).ConclusionsBandemia and low serum albumin are independent predictors of failure of infliximab rescue therapy in acute severe ulcerative colitis. Serum albumin ≤ 2.5 g/dl and band neutrophil count ≥ 13% had a 100% positive predictive value for 90-day colectomy.

Patients with inflammatory bowel disease (IBD) have an increased risk of venous thrombotic events. The risk of arterial thrombotic events in IBD, however, has been less well characterized. We explored whether Crohn's disease (CD) and ulcerative colitis (UC) are associated with a higher risk for thrombotic events involving the mesenteric, cardiac, or cerebral arteries. Using the Thomson Reuters MarketScan Research claims database, we conducted a retrospective cohort study of IBD patients observed for the occurrence of pre-defined thrombotic events. For comparison, four non-IBD controls were age-, sex-, and index date-matched to each IBD case. The outcomes of interest were acute mesenteric ischemia, transient ischemic attack, cerebrovascular occlusion, atherosclerosis, peripheral vascular disease, and myocardial infarction. We performed a multivariate analysis adjusting for potential confounders for thrombotic events, including hypertension, diabetes, hyperlipidemia, and, in women, the use of contraceptives. We calculated the adjusted hazard ratios (HRs) for each event by comparing IBD patients with controls and used the log-rank test to determine statistical significance. The study included 17,487 IBD patients and 69,948 controls. Overall, IBD patients had a markedly increased risk of acute mesenteric ischemia (HR=11.2, P<0.001). IBD patients as a whole did not have an increased risk of other arterial thrombotic events, including myocardial infarction and transient ischemic attack, when compared with controls. However, women with IBD who were over the age of 40 years had a higher risk of myocardial infarction (HR=1.6, P=0.003). In addition, women with IBD below the age of 40 years who showed a significantly higher risk for stroke (HR=2.1, P=0.04). For all events, the risks in CD and UC were similar. Patients with IBD have a markedly increased risk of acute mesenteric ischemia. Subgroup analysis reveals that women over the age of 40 years with IBD are at increased risk of myocardial infarction, whereas those below the age of 40 years exhibit a two-fold higher risk for stroke. In contrast, men with IBD did not share these same risks for arterial thrombotic events.

Indirect costs associated with impaired productivity at work (presenteeism) due to inflammatory bowel disease (IBD) are a major contributor to health expenditures. Studies estimating indirect costs in the United States did not take presenteeism into account. We aimed to quantify work limitations and presenteeism and its associated costs in an IBD population to generate recommendations to reduce presenteeism and decrease indirect costs.MethodsWe performed a prospective study at a tertiary IBD center. During clinic visits, work productivity, work-related problems and adjustments, quality of life, and disease activity were assessed in patients with IBD. Work productivity and impairment were assessed in a control population as well. Indirect costs associated with lost work hours (absenteeism) and presenteeism were estimated, as well as the effect of disease activity on those costs.ResultsOf the 440 included patients with IBD, 35.6% were unemployed. Significantly more presenteeism was detected in patients with IBD (62.9%) compared with controls (27.3%) (P = 0.004), with no significant differences in absenteeism. Patients in remission experienced significantly more presenteeism than controls (54.7% versus 27.3%, respectively, P < 0.01), and indirect costs were significantly higher for remissive patients versus controls ($17,766 per yr versus $9179 per yr, respectively, P < 0.03). Only 34.3% had made adjustments to battle work-related problems such as fatigue, irritability, and decreased motivation.ConclusionsPatients with IBD in clinical remission still cope with significantly more presenteeism and work limitations than controls; this translates in higher indirect costs and decreased quality of life. The majority have not made any adjustments to battle these problems.

The management of inflammatory bowel disease in the older patient extends beyond the gastrointestinal tract. Pre-existing comorbidities, polypharmacy, functional status and physical reserve can impact disease course, response to therapy and quality of life. Current therapeutic endpoints may not be as immediately applicable to the older IBD patient at higher risk for adverse outcomes. This review focuses on the latest studies addressing the natural history, clinical course and therapeutic outcomes among the older IBD cohort.
