- BACKGROUND & AIMS: Diagnosis of inflammatory bowel diseases (IBD) is increasing among elderly persons (60 years or older). We performed a nationwide population-based study to estimate incidence and treatment.METHODS: We identified all incident IBD cases in Sweden, from 2006 through 2013, using national registers, and up to 10 matched population comparator subjects. We collected data on the patients' health care contacts and estimated incidence rates, health service burden, pharmacologic treatments, extra-intestinal manifestations, and surgeries in relation to age of IBD onset (pediatric, less than 18 years; adults, 18-59 years; elderly, 60 years or older).RESULTS: Of 27,834 persons diagnosed with incident IBD, 6443 (23%) had a first diagnosis of IBD at 60 years or older, corresponding to an incidence rate of 35/100,000 person-years (10/100,000 person-years for Crohn's disease, 19 /100,000 person-years for ulcerative colitis, and 5/100,000 person-years for IBD unclassified). During a median follow-up period of 4.2 years (range 0-9 years), elderly patients had less IBD-specific outpatient health care but more IBD-related hospitalizations and overall health care use than adult patients with IBD. Compared to patients with pediatric or adult onset, elderly patients used fewer biologics and immunomodulators, but more systemic corticosteroids. Occurrence of extra-intestinal manifestations was similar in elderly and adult patients, but bowel surgery was more common in the elderly (13% after 5 years vs 10% in adults) (P<.001). The absolute risk of bowel surgery was higher in the elderly than in the general population, but in relative terms, the risk increase was larger in younger age groups.CONCLUSIONS: In a nationwide cohort study in Sweden, we associated diagnosis of IBD at age 60 years or older with a lower use of biologics and immunomodulators but higher absolute risk of bowel surgery, compared to diagnosis at a younger age. The large differences in pharmacological treatment of adults and elderly patients are not necessarily due to a milder course of disease and warrant further investigation.

- BACKGROUND: Inflammatory bowel disease has been linked to increasing healthcare costs, but longitudinal data on other societal costs are scarce.AIM: To assess costs, including productivity losses, in patients with prevalent Crohn's disease (CD) or ulcerative colitis (UC) in Sweden between 2007 and 2020.METHODS: We linked data from national registers on all patients with CD or UC and a matched (sex, birthyear, healthcare region and education) reference population. We assessed mean costs/year in Euros, inflation-adjusted to 2020, for hospitalisations, out-patient visits, medications, sick leave and disability pension. We defined excess costs as the mean difference between patients and matched comparators.RESULTS: Between 2007 and 2020, absolute mean annual societal costs in working-age (18-64 years) individuals decreased by 17% in CD (-24% in the comparators) and by 20% in UC (-27% in comparators), due to decreasing costs from sick leave and disability, a consequence of stricter sick leave regulations. Excess costs in 2007 were dominated by productivity losses. In 2020, excess costs were mostly healthcare costs. Absolute and excess costs increased in paediatric and elderly patients. Overall, costs for TNF inhibitors/targeted therapies increased by 274% in CD and 638% in UC, and the proportion treated increased from 5% to 26% in CD, and from 1% to 10% in UC.CONCLUSION: Between 2007 and 2020, excess costs shifted from productivity losses to direct healthcare costs; that is, the patients' compensation for sickness absence decreased, while society increased its spending on medications. Medication costs were driven both by expanding use of TNF inhibitors and by high costs for newer targeted therapies.

- Background and Aims: Crohn's disease may affect the ability to work and lead to permanent disability. We aimed to investigate work loss in prevalent patients.Methods: We identified patients with Crohn's disease and general population comparators matched by sex, birth year, healthcare region and education. We assessed days of sick leave and disability pension retrieved from the Swedish Social Insurance Agency and estimated the absolute and relative risk of receiving disability pension [minimum 25% work impairment].Results: In 2014, the 20638 Crohn's disease patients [median age 44 years] had more than twice as many mean lost workdays [disability pension: 44; sick leave: 19] as the 102038 comparators [disability pension: 20; sick leave: 8], mean difference 35 days [95% confidence interval 33-37]. However, the majority had no lost workdays [68% of patients and 85% of comparators]. The proportion of patients receiving disability pension was 15% (6.5% in the comparators, risk ratio 2.34 [2.25-2.43]) and was higher in all subgroups, especially in female patients [28% vs 13% in the comparators], in those with ≤9 years of education [41% vs 23%] and in ages 60-64 years [46% vs 25%]. The relative risk of disability pension within the patient cohort [adjusted for age, sex, region and education] was higher in patients with complicated disease behaviour, extraintestinal manifestations, need of surgery or treatment with biologics. The differences between patients and comparators remained when comparing other calendar years [2006-2013].Conclusion: Work loss was found in approximately one-third of patients. The mean number of lost workdays was twice as high as in the comparators.

- BACKGROUND/AIM: Patients with inflammatory bowel disease (IBD) have more work disability than the general population. We aimed to estimate the monetary cost of IBD for the individual through assessment of earnings in relation to diagnosis.METHODS: Through linkage of national registers we identified patients aged 30-55 years at first IBD diagnosis in Sweden 2002-2011, and same-sex IBD-free siblings. We estimated taxable earnings and disposable income from 5 years before to 5 years after diagnosis.RESULTS: The 5,961 patients (27% Crohn's disease, 68% ulcerative colitis, 4.3% IBD unclassified) had similar taxable earnings as their 7,810 siblings until the year of diagnosis, when earnings decreased and remained lower than in siblings during follow-up. The adjusted difference in earnings over the entire 5-year period after diagnosis was -5% (-8,212€; 95%CI: -11,458 to-4,967). The difference was larger in women than in men, and larger in Crohn's disease than in ulcerative colitis. When stratifying for sex and IBD subtype and comparing earnings during each year of follow-up, the median annual earnings were lower in women with Crohn's disease and ulcerative colitis than in their sisters during all years of follow-up, whereas the men had similar annual taxable earnings as their brothers. The disposable income was similar between patients and siblings during the investigated time period.CONCLUSION: From the year of diagnosis and at least 5 years onwards, patients with IBD had 5% lower earnings than siblings, mainly explained by differences between women with IBD and their sisters. However, there were no differences in disposable income.

- Background: The aim of this study was to examine work loss in patients with Crohn's disease.Methods: Using nationwide registers, we identified incident patients with Crohn's disease (2007-2010) and population comparator subjects without inflammatory bowel disease, matched by age, sex, calendar year, health care region, and education level. We assessed the number of lost workdays due to sick leave and disability pension from 5 years before to 5 years after first diagnosis of Crohn's disease or end of follow-up (September 30, 2015).Results: Among the 2015 incident Crohn's disease patients (median age, 35 years; 50% women), both the proportion with work loss and the mean annual number of lost workdays were larger 5 years before diagnosis (25%; mean, 45 days) than in the 10,067 comparators (17%; mean, 29 days). Increased work loss was seen during the year of diagnosis, after which it declined to levels similar to before diagnosis. Of all patients, 75% had no work loss 24-12 months before diagnosis. Of them, 84% had full work ability also 12-24 months after diagnosis. In patients with total work loss (8.3% of all) before diagnosis, 83% did not work after. Among those with full work ability before diagnosis, the absolute risk of having total work loss after diagnosis was 1.4% (0.43% in the comparators). Our results were consistent across several sensitivity analyses using alternative definitions for date of diagnosis.Conclusions: Patients with Crohn's disease had increased work loss several years before diagnosis, possibly explained by comorbidity or by diagnostic delay.

- Background: There are limited data on population-wide assessment of cost in Crohn's disease (CD) and ulcerative colitis (UC).Aim: To estimate the societal cost of actively treated CD and UC in Sweden.Methods: We identified 10 117 prevalent CD and 19 762 prevalent UC patients, aged ≥18 years on 1 January 2014 and 4028 adult incident CD cases and 8659 adult incident UC cases (2010-2013) from Swedish Patient Register. Each case was matched to five population comparators. Healthcare costs were calculated from medications, outpatient visits, hospitalisations and surgery. Cost of productivity losses was derived from disability pension and sick leave.Results: The mean annual societal costs per working-age patient (18-64 years) with CD and UC were $22 813 (vs $7533 per comparator) and $14 136 (vs $7351 per comparator) respectively. In patients aged ≥65 years, the mean annual costs of CD and UC were $9726 and $8072 vs $3875 and $4016 per comparator respectively. The majority of cost for both CD (56%) and UC (59%) patients originated from productivity losses. Higher societal cost of working-age CD patients as compared to UC patients was related to greater utilisation of anti-TNF (22.2% vs 7.4%) and increased annual disability pension (44 days vs 25 days). Among incident CD and UC patients, the mean total cost over the first year per patient was over three times higher than comparators.Conclusion: In Sweden, the societal cost of incident and prevalent CD and UC patients was consistently two to three times higher than the general population.

- OBJECTIVE: Crohn's disease (CD) is associated with increased risk of small bowel cancer (SBC), but previous studies have been small. We aimed to examine the risk of incident SBC and death from SBC in patients with inflammatory bowel disease (IBD).DESIGN: In a binational, population-based cohort study from Sweden and Denmark of patients with IBD during 1969-2017 and matched reference individuals from the general population, we evaluated the risk of incident SBC and death from SBC. Cox regression was used to estimate adjusted hazard ratios (aHRs).RESULTS: We identified 161 896 individuals with IBD (CD: 47 370; UC: 97 515; unclassified IBD: 17 011). During follow-up, 237 cases of SBC were diagnosed in patients with IBD (CD: 24.4/100 000 person-years; UC: 5.88/100 000 person-years), compared with 640 cases in reference individuals (2.81/100 000 person-years and 3.32/100 000 person-years, respectively). This corresponded to one extra case of SBC in 385 patients with CD and one extra case in 500 patients with UC, followed up for 10 years. The aHR for incident SBC was 9.09 (95% CI 7.34 to 11.3) in CD and 1.85 (95% CI 1.43 to 2.39) in UC. Excluding the first year after an IBD diagnosis, the aHRs for incident SBC decreased to 4.96 in CD and 1.69 in UC. Among patients with CD, HRs were independently highest for recently diagnosed, childhood-onset, ileal and stricturing CD. The relative hazard of SBC-related death was increased in both patients with CD (aHR 6.59, 95% CI 4.74 to 9.15) and patients with UC (aHR 1.57; 95% CI 1.07 to 2.32).CONCLUSION: SBC and death from SBC were more common in patients with IBD, particularly among patients with CD, although absolute risks were low.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Celiac disease (CD) is associated with many immune-mediated conditions, but a definitive epidemiological association between CD and juvenile idiopathic arthritis (JIA) or rheumatoid arthritis (RA) has not been established. We quantified the risk of JIA and RA among patients with CD using a population-based cohort.METHODS: We identified patients diagnosed with biopsy-proven CD between 2004 and 2017 using data from a national histopathology cohort in Sweden. Each patient was matched by age, sex, calendar year, and geographic region to reference individuals in the general population. We calculated the incidence and estimated the relative risk, through Cox proportional hazards models, of JIA in individuals with CD aged ≥18.RESULTS: We identified 24,014 individuals with CD who were matched to 117,397 reference individuals from the general population. Among individuals aged <18, the incidence rate of JIA was 5.9 per 10,000 person-years in patients with CD and 2.2 per 10,000 person-years in the general population (n events = 40 and 73, respectively; hazard ratio [HR] 2.68, 95% confidence interval 1.82-3.95) over a follow-up of 7.0 years. Among individuals aged >= 18, the incidence of RA was 8.4 per 10,000 person-years in CD and 5.1 per 10,000 person-years in matched comparators (n events = 110 and 322, respectively; HR 1.70, 95% confidence interval 1.36-2.12) over a follow-up of 8.8 years.DISCUSSION: Among children with CD, JIA develops nearly 3 times as often as it does in the general population, and among adults with CD, RA occurs nearly 2 times as often. Clinicians caring for patients with CD with joint symptoms should have a low threshold to evaluate for JIA or RA.

- Background: Inflammatory bowel disease (IBD) has been associated with hepatobiliary cancer, but existing evidence is poor. We evaluated risk of death from hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), and extrahepatic cholangiocarcinoma (ECC) among patients with IBD.Methods: This Swedish/Danish population-based cohort study (1969-2017) followed patients with IBD and 1:10 matched population comparators from their diagnosis/match date until death, emigration, or end of follow-up.Results: Among the 97,496 patients with ulcerative colitis/963,026 comparators, we found 66/390 HCC-deaths, 120/173 ICC-deaths, and 91/220 ECC-deaths (median follow-up 10 years); the 10-year-mortality was 0.5% (per mille) for HCC, 0.6% for ICC, and 0.4% for ECC, which decreased to 0.3%, 0.4%, and 0.2%, respectively, in 2003-2017. Overall hazard ratios (HR) were 1.83 [95% confidence interval (CI), 1.41-2.38] for HCC-, 7.33 (95% CI, 5.81-9.25) for ICC-, and 4.46 (95% CI, 3.49-5.70) for ECC-deaths. A total of 22/66 HCC-deaths, 87/120 ICC-deaths, and 55/91 ECC-deaths occurred among patients with ulcerative colitis with primary sclerosing cholangitis (PSC), corresponding to 10-year-mortality of 6.7%, 26.2%, and 17.2%, respectively. Among 47,399 patients with Crohn's disease (median follow-up 11 years), 10-year-mortality from HCC (n = 28), ICC (n = 28), and ECC (n = 24) were 0.3%, 0.1%, and 0.3%, respectively, and corresponding HRs were 1.96 (95% CI, 1.31-2.93), 3.33 (95% CI, 2.19-5.09), and 3.10 (95% CI, 1.97-4.87). One of 28 HCC-deaths, 14/28 ICC-deaths (10-year-mortality 19%), and 12/24 ECC-deaths (10-year-mortality 14%) occurred after PSC.Conclusions: Risk of HCC-, ICC-, and ECC-deaths was low in patients with IBD and decreased over time. However, a large proportion of deaths occurred after PSC.Impact: Guidelines on specific surveillance strategies for patients with IBD with PSC, but not those without PSC, are needed.
