RESUMO
BACKGROUND/AIMS: To determine real-world medical and surgical treatment patterns in elderly-onset inflammatory bowel disease in a nationwide cohort, and to investigate associations between frailty and treatment choices. METHODS: Norwegian health registries were used to identify adult-onset (born 1950-1989) and elderly-onset (born 1910-1949) patients with Crohn's disease (CD) and ulcerative colitis (UC) diagnosed 2010-2017 (n = 13,006). Patients were classified as no, low and intermediate/high frailty risk after the Hospital Frailty Risk Score. Outcomes included use of medical and surgical treatment. RESULTS: Within five years, elderly-onset patients received less biologics (13% [CD], 7% [UC]) and immunomodulators (24% [CD], 11% [UC]), and major surgery was more frequent (22% [CD], 9% [UC]) than in adult-onset. Respective log rank tests were significant (p < 0.01). Compared to no frailty risk groups, elderly-onset UC with intermediate/high frailty risk had lower probability of starting biologics (4% versus 9%), immunomodulators (7% versus 13%) and 5-aminosalisylic acids (66% versus 84%), and elderly-onset CD with intermediate/high frailty risk had higher probability of starting prednisolone (67% versus 49%). Respective log rank tests were significant (p < 0.05). CONCLUSIONS: Elderly-onset patients received less biologics and immunomodulators and a larger proportion underwent major surgery. Frailty risk in elderly-onset patients was associated with increased use of prednisolone, and less use of 5-aminosalisylic acids, immunomodulators and biologics.

Background: Vedolizumab has since 2021 been available as a subcutaneous formulation. We aimed to assess 18-month drug persistence and possible predictive factors associated with discontinuation, safety, serum drug profile, drug dosing, and disease activity in a real-world cohort of patients with inflammatory bowel disease switched from intravenous to subcutaneous vedolizumab maintenance treatment. Methods: Eligible patients were switched to subcutaneous vedolizumab and followed for 18 months or until discontinuation of subcutaneous treatment. Data on preferred route of administration, adverse events, drug dosing, serum-vedolizumab, disease activity, fecal calprotectin, and C-reactive protein were collected. Persistence was described using Kaplan-Meier analysis. The impact of clinical and biochemical variables on persistence was analyzed with Cox proportional hazard models. Results: We included 108 patients, and the estimated 18-month drug persistence was 73.6% (95% CI [64.2-80.1]). Patients in clinical remission at switch were less likely to discontinue SC treatment (HRâ =â 0.34, 95% CI [0.16-0.73], Pâ =â .006), and patients favoring intravenous treatment at switch were almost 3 times more likely to discontinue (HRâ =â 2.78, 95% CI [1.31-5.90], Pâ =â .008). Four patients discontinued subcutaneous vedolizumab due to injection site reactions. At 18 months, 88% of patients administered subcutaneous vedolizumab with an interval ofâ ≥â 14 days, and serum-vedolizumab was 39.1 mg/L. Disease activity was stable during follow-up. Conclusions: Three of the four patients remained on subcutaneous vedolizumab after 18 months, a large proportion received treatment at standard dosing intervals, and disease activity remained stable. This indicates that switching from intravenous to subcutaneous vedolizumab treatment is convenient and safe.
RESUMO
OBJECTIVE: Vedolizumab (VDZ) for subcutaneous (SC) administration has recently become available. We aimed to assess feasibility, safety and clinical outcome when switching from intravenous (IV) to SC VDZ maintenance treatment in a real world cohort of patients with inflammatory bowel disease (IBD) followed by therapeutic drug monitoring (TDM). METHODS: Eligible IBD patients were switched from IV to SC treatment and assessed six months prior to switch, at baseline and six, twelve and twenty-six weeks after switch. Primary outcome was proportion of patients on SC treatment after 26 weeks. Secondary outcomes included adverse events (AEs), clinical disease activity, biochemical markers, treatment interval, serum-VDZ (s-VDZ), preferred route of administration and health-related quality of life. RESULTS: In total, 108 patients were switched. After 26 weeks, 100 patients (92.6%) were still on SC treatment and median s-VDZ was 47.6 mg/L (IQR 41.3 - 54.6). The most frequent AE was injection site reaction (ISR), reported by 20 patients (18.5%). There were no clinically significant changes in disease activity, biochemical markers and quality of life. The proportion of patients preferring SC administration increased from 28.0% before switch to 59.4% after 26 weeks (p < 0.001). CONCLUSIONS: Nine out of ten patients still received SC treatment after 26 weeks. No change in disease activity occurred, and levels of serum VDZ increased. Although almost one fifth of patients experienced ISRs, a higher proportion favored SC administration at 26 weeks. This study demonstrates that SC maintenance treatment is a safe and feasible alternative to IV treatment.

OBJECTIVES: Immune responses following SARS-CoV-2 vaccination in patients with inflammatory bowel disease (IBD) are not well characterized. The aims of this study were to explore the serological response associated with IBD, and immunosuppressive medications including serum concentrations of biologics and thiopurine metabolites. MATERIALS AND METHODS: This prospective, observational study included adult patients with ulcerative colitis (UC) and Crohn's disease (CD), and healthy controls. Antibodies to the receptor-binding domain of SARS-CoV-2 spike proteins, and serum concentrations of ongoing biologic and immunomodulatory medications were assessed prior to, and 2-5 weeks after the second vaccine dose. Serologic response was defined as anti-Spike antibodies ≥70 AU/ml. RESULTS: In 958 IBD patients (380 UC, 578 CD) and 323 healthy controls, the median (Q1; Q3) anti-Spike antibody level (AU/ml) was lower in patients (618 (192; 4370)) compared to controls (3355 (896; 7849)) (p < 0.001). The antibody levels were lower in CD (439 (174; 3304)) compared to UC (1088 (251; 5975)) (p < 0.001). No associations were demonstrated between antibody levels and serum drug concentrations for TNF inhibitor (TNFi), vedolizumab and ustekinumab. Patients receiving TNFi + thiopurines with a subtherapeutic 6-thioguanine nucleotide (6-TGN) level had higher response rate (93%) compared to patients with 6-TGN within the therapeutic range (53%) (p = 0.003). A diagnosis of UC, mRNA-1273 vaccine, and other treatments than TNFi + thiopurines were associated with humoral response. CONCLUSIONS: Patients with CD had an attenuated humoral response to SARS-COV-2 vaccination as compared to patients with UC. The lack of association between serum levels of biologics and serologic response indicates vaccination regardless of proximity to drug administration.

BACKGROUND: Despite the increasing use of biologics in patients with inflammatory bowel disease (IBD), real-world data about outcomes in the era of biologics remain inconclusive. AIMS: To investigate trends in surgeries, hospitalisations and medication use in patients with IBD in a multinational, population-based cohort METHODS: We included 42,894 patients with ulcerative colitis (UC) and 24,864 with Crohn's disease (CD) who were diagnosed between 2010 and 2017 in Denmark, Norway and Sweden. We extracted data about surgeries, hospitalisations and medications from national registries and compared across countries and diagnosis years. RESULTS: Between 2010 and 2017, 2-year surgery rates were 4-7% in UC and 10-15% in CD and were stable over time. Two-year hospitalisation rates increased in Denmark (UC: 20% to 35%; CD: 27% to 32%) but were stable in Norway and Sweden (fluctuating between 33% and 37% in UC, and 46% and 52% in CD). Two-year rates of biologic use increased in both UC (7% to 16% in Denmark, 8% to 18% in Norway) and CD (22% to 26% in Denmark; 21% to 35% in Norway). Two-year rates of immunomodulator use increased in Norway (from 14% to 23% in UC; 37% to 45% in CD) and Sweden (from 41% to 52% in CD), but were stable in Denmark (between 17% and 21% in UC; 39% to 46% in CD). CONCLUSION: Between 2010 and 2017, surgery rates among Scandinavian patients with IBD remained stable, with no clear changes in hospitalisation rates despite the increasing use of immunomodulators and biologics.

OBJECTIVES: The use of biologic therapy in inflammatory bowel disease (IBD) is likely to increase with lower costs and more biologics and biosimilars becoming available. Our aim was to estimate the trends in use of first-line biologics during the first year after diagnosis in a Norwegian IBD population from 2010 to 2016. METHODS: Data were collected from the Norwegian National Patient Registry and Norwegian Prescription Database. Patients defined as incident IBD cases between 2010 and 2016 were included and followed for 12 months. Patients were stratified by year of diagnosis to examine change over time. Chi-square test was used for calculations on proportions. Time from diagnosis to first biologic was calculated by Kaplan-Meier failure estimates. RESULTS: 14,645 patients were included, 5283 (36%) with Crohn's disease (CD) and 9362 (64%) with ulcerative colitis (UC). In the 2010 and 2016 cohort, the proportion initiating biologics increased from 17% to 33% (p < .001) for CD and 7% to 13% (p < .001) for UC. The most frequently used first-line biologics were infliximab (CD: 64% and UC: 82%) and adalimumab (CD: 36% and UC: 15%). The highest registered use of adalimumab was in the 2012 cohort (CD: 56% and UC: 39%). In the 2014-2016 cohorts, infliximab was the most used first-line biologic for both CD and UC. CONCLUSIONS: The proportion of IBD patients initiating biologics within 12 months after diagnosis increased between 2010 and 2016. The use of infliximab as first-line biologic increased after the approval of biosimilar infliximab in 2013.

BACKGROUND: Countries have different diagnostic procedures and treatment regimens for inflammatory bowel disease (IBD) patients. In addition to differences in population characteristics, completeness of data and health registries, different follow-up time and case definitions can have a large impact on estimates of the incidence and prevalence of IBD. AIM: The aim of this study was to use hospital and prescription data to estimate incidence and prevalence of Crohn's disease (CD) and ulcerative colitis (UC), using different case definitions. METHODS: This study used nationwide data from the Norwegian Patient Registry (2008 to 2017) and the Norwegian Prescription Database (2004 to April 2018). Incidence and prevalence were estimated using different case definitions of an IBD patient, varying the number of IBD-related hospital visits and IBD prescriptions required. The base case definition included patients with at least one IBD hospital visit and two IBD prescriptions or two IBD hospital visits. RESULTS: From 2010 to 2017, 16,758 incident IBD patients fulfilled our base case definition, with 6045 diagnosed with CD (36.1%) and 10,713 (63.9%) with UC. For CD, 47.2% of the patients were male while 53.8% of UC patients were male. The base case incidence varied between 14.1 and 16.0 per 100,000 person-years for CD and 24.7 and 28.4/100,000 person-years for UC patients in the years 2010-2017. When we required at least two IBD hospital visits, not utilizing the prescription data, the CD incidence was 22.3 per 100,000 person-years in 2010 and 13.9 per 100,000 person-years in 2017. For UC, the incidence was 47.4 and 20.6 per 100,000 person-years in 2010 and 2017. In 2017, the prevalence of CD was 0.27% (95% CI: 0.26-0.27) and 0.50% (95% CI: 0.490-0.502) for UC. CONCLUSION: According to our base case definition, the incidence of IBD in Norway was stable from 2010 to 2017. Both the incidence and prevalence of IBD in Norway is among the highest in the world. Moreover, the study also highlights the consequences of different case definitions.
