- 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 AND AIMS: Inflammatory diseases are associated with an increased risk of incident major adverse cardiovascular events (MACE). However, data on MACE are lacking in large population-based histopathology cohorts of microscopic colitis (MC).METHODS: This study included all Swedish adults with MC without previous cardiovascular disease (1990- 2017; N = 11,018). MC and subtypes (collagenous colitis and lymphocytic colitis) were defined from prospectively recorded intestinal histopathology reports from all pathology departments (n = 28) in Sweden. MC patients were matched for age, sex, calendar year, and county with up to 5 reference individuals (N = 48,371) without MC or cardiovascular disease. Sensitivity analyses included full sibling comparisons, and adjustment for cardiovascular medication and healthcare utilization. Multivariable-adjusted hazard ratios for MACE (any of ischemic heart disease, congestive heart failure, stroke, and cardiovascular mortality) were calculated using Cox proportional hazards modelling. RESULTS: Over a median of 6.6 years of follow-up, 2181 (19.8%) incident cases of MACE were confirmed in MC patients and 6661 (13.8%) in reference individuals. MC patients had a higher overall risk of MACE outcomes compared with reference individuals (adjusted hazard ratio [aHR], 1.27; 95% confidence interval [CI], 1.21-1.33) and higher risk of its components: ischemic heart disease (aHR, 1.38; 95% CI, 1.28-1.48), congestive heart failure (aHR, 1.32; 95% CI, 1.22-1.43), and stroke (aHR, 1.12; 95% CI, 1.02-1.23) but not cardiovascular mortality (aHR, 1.07; 95% CI, 0.98-1.18). The results remained robust in the sensitivity analyses.CONCLUSIONS: Compared with reference individuals, MC patients had a 27% higher risk of incident MACE, equal to 1 extra case of MACE for every 13 MC patients followed for 10 years.

- Background: Gastrointestinal inflammation has been linked with Parkinson's disease (PD). Microscopic colitis (MC) is an intestinal inflammatory disease with unknown relationship with PD.Objective: This study aimed to examine the association of MC with PD risk.Methods: In this nationwide matched cohort study in Sweden, PD incidence was compared between 12,609 patients with histologically confirmed MC and a matched population cohort of 58,879 MC-free individuals and a sibling cohort comprising all unaffected siblings of the MC patients (N-MC/N-Sibling = 6281/12,351). Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox regression models.Results: During a mean follow-up of similar to 7 years, we identified 449 incident PD diagnoses among the MC patients and the population cohort. Overall, MC was associated with an adjusted HR of 1.76 for PD, but the association attenuated substantially during follow-up. In the time-varying effects model, PD hazard was 3.45-fold (95% CI: 2.42, 4.93) higher during the first 2 years after biopsy and 1.80-fold (95% CI: 1.23, 2.64) higher during the following 3 years among MC versus MC-free individuals but was not different beyond 5 years after biopsy (HR: 1.03; 95% CI: 0.68, 1.54). This temporal pattern of MC-PD associations persisted when comparing MC patients to their siblings. In a post hoc case-control analysis, we also detected a strong association between MC and preexisting PD (odds ratio: 3.46; 95% CI: 2.91, 4.12).Conclusions: Our findings suggest that MC may not be a risk factor for PD; instead, it may co-occur with PD as a comorbidity or develop after a diagnosis of PD.

- Objective: To examine the association between microscopic colitis (MC) and Parkinson’s disease (PD) risk.Background: Gastrointestinal inflammation has been linked with PD. MC is a chronic intestinal inflammatory disease; however, its relationship with PD is unknown.Design/Methods: A population-based matched cohort study was conducted to estimate the association between MC and incident PD diagnosis using Cox regression models. An exposed cohort of 12,609 MC patients diagnosed 1990–2017 and aged ≥35 years at diagnosis was identified from the Epidemiology Strengthened by histoPathology Reports in Sweden cohort (ESPRESSO). Two unexposed cohorts were compared to: a population cohort comprising 58,879 MC-free individuals randomly selected from the population and 1:5 matched to each MC patient by age, sex, year of biopsy and county of residence at the time of biopsy; and a sibling cohort (NMC/NSibling=6,281/12,351) including all siblings of the MC patients. Follow-up was from the date of biopsy until December 31st 2016 at latest.Results: During a mean follow-up of ~7 years, we identified 449 incident PD diagnoses among the MC patients and their matched population cohort. The overall PD risk was 76% higher among MC versus MC-free individuals; but the association attenuated substantially during follow-up. In the time-varying effects model, PD risk was 3.45-fold (95% CI: 2.42, 4.93) higher during the first 2 years after biopsy and 1.80-fold (95% CI: 1.23, 2.64) higher during the following 3 years among MC versus MC-free individuals, but was not differential beyond 5 years after biopsy (hazard ratio=1.03; 95% CI: 0.68, 1.54). This temporal pattern of MC-PD associations persisted in sibling analyses. Using a matched case-control design, we also observed a higher prevalence of prior PD diagnosis among MC patients than the matched MC-free individuals (odds ratio=3.46; 95% CI: 2.91, 4.12).Conclusions: Our findings suggest that MC may not be a risk factor, but rather a comorbidity or complication of PD.

- OBJECTIVE: To examine the relationship between Mediterranean diet and risk of later-onset Crohn's disease (CD) or ulcerative colitis (UC).DESIGN: We conducted a prospective cohort study of 83 147 participants (age range: 45-79 years) enrolled in the Cohort of Swedish Men and Swedish Mammography Cohort. A validated food frequency questionnaire was used to calculate an adherence score to a modified Mediterranean diet (mMED) at baseline in 1997. Incident diagnoses of CD and UC were ascertained from the Swedish Patient Register. We used Cox proportional hazards modelling to calculate HRs and 95% CI.RESULTS: Through December of 2017, we confirmed 164 incident cases of CD and 395 incident cases of UC with an average follow-up of 17 years. Higher mMED score was associated with a lower risk of CD (Ptrend=0.03) but not UC (Ptrend=0.61). Compared with participants in the lowest category of mMED score (0-2), there was a statistically significant lower risk of CD (HR=0.42, 95% CI 0.22 to 0.80) but not UC (HR=1.08, 95% CI 0.74 to 1.58). These associations were not modified by age, sex, education level, body mass index or smoking (all Pinteraction >0.30). The prevalence of poor adherence to a Mediterranean diet (mMED score=0-2) was 27% in our cohorts, conferring a population attributable risk of 12% for later-onset CD.CONCLUSION: In two prospective studies, greater adherence to a Mediterranean diet was associated with a significantly lower risk of later-onset CD.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: To assess the relationship between diet quality and risk of older-onset Crohn's disease (CD) and ulcerative colitis (UC).METHODS: We conducted a prospective cohort study of 83,147 participants from the Swedish Mammography Cohort and the Cohort of Swedish Men. We used food frequency questionnaire to calculate adherence scores to multiple derived health diet patterns: Alternate Healthy Eating Index (AHEI), Healthy Eating Index-2015 (HEI-2015), Healthful Plant-Based Diet Index (HPDI), and modified Mediterranean Diet Score (mMED) at baseline in 1997 in both cohorts. Diagnoses of CD and UC were retrieved from the Swedish Patient Register. We used Cox proportional hazards modeling to estimate the adjusted hazard ratios (HRs) and 95% CIs.FINDINGS: Through December of 2017, we confirmed 164 incident cases of CD and 395 incident cases of UC. Comparing the highest to the lowest quartiles, the adjusted HRs of CD were 0.73 (95% CI, 0.48, 1.12, Ptrend = 0.123) for AHEI; 0.90 (0.57, 1.41, Ptrend = 0.736) for HEI 2015; 0.52 (95% CI 0.32, 0.85, Ptrend = 0.011) for HPDI; and 0.58 (95% CI 0.32, 1.06, Ptrend = 0.044) for mMED. In contrast, we did not observe an association between any diet quality score and risk of UC.INTERPRETATION: We found that several healthy eating patterns were associated with a lower risk of older-onset CD. Our findings provide a rationale for adapting different healthy dietary patterns based on individuals' food preferences and traditions for designing future prevention strategies for IBD.

- BACKGROUND AND AIMS: Gastrointestinal infections have been linked to changes in the composition and function of gut microbiome and development of inflammatory bowel diseases. We therefore sought to examine the relationship between gastroenteritis and risk of microscopic colitis (MC).METHODS: We conducted a case-control study of all adult patients with MC diagnosed between 1990 and 2016 in Sweden matched to up to 5 general population controls according to age, sex, calendar year, and county. Cases of MC were identified using Systematized Nomenclature of Medicine codes from the ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) study, a cohort of gastrointestinal pathology reports from all 28 pathology centers in Sweden. We used logistic regression modeling to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs).RESULTS: Through December of 2016, we matched 13,468 MC cases to 64,479 controls. The prevalence of previous diagnosed gastrointestinal infection was 7.5% among patients with MC, which was significantly higher than in controls (3.0%, P-comparison < .001). After adjustment, gastroenteritis was associated with an increased risk of MC (aOR 2.63; 95% CI 2.42-2.85). Among specific pathogens, Clostridioides difficile (aOR 4.39; 95% CI 3.42-5.63), Norovirus (aOR 2.87; 95% CI 1.66-4.87), and Escherichia species (aOR 3.82; 95% CI 1.22-11.58), but not Salmonella species, were associated with an increased risk of MC. The association between gastrointestinal infections and risk of MC was stronger for collagenous subtype (aOR 3.23; 95% CI 2.81-3.70) as compared with lymphocytic colitis (aOR 2.51; 95% CI 2.28-2.76; P-heterogeneity = .005). The associations remained significant after adjustment for immune-mediated conditions and polypharmacy and when compared with unaffected siblings.CONCLUSION: In a nationwide study, we found that gastrointestinal infection, particularly Clostridioides difficile, is associated with an increased risk of subsequent MC.

- 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.
