- BACKGROUND: Inflammatory bowel disease (IBD) has been linked to an increased risk of colorectal neoplasia. However, the types and risks of specific polyp types in IBD are less clear.METHODS: We identified 41,880 individuals with IBD [Crohn's disease (CD: n=12,850); Ulcerative colitis (UC): n=29,030)] from Sweden matched with 41,880 reference individuals. Using Cox regression, we calculated adjusted hazard ratios (aHRs) for neoplastic colorectal polyps (Tubular, Serrated/Sessile, Advanced and Villous) defined by histopathology codes.RESULTS: During follow-up, 1648 (3.9%) IBD patients and 1143 (2.7%) reference individuals had an incident neoplastic colorectal polyp, corresponding to an incidence rate of 46.1 and 34.2 per 10,000 person-years, respectively. This correlated to an aHR of 1.23 (95% CI 1.12-1.35) with the highest HRs seen for sessile serrated polyps (8.50, 95% CI 1.10-65.90) and traditional serrated adenomas (1.72, 95% CI 1.02-2.91). aHRs for colorectal polyps were particularly elevated in those diagnosed with IBD at a young age and after 10 years after diagnosis. Both absolute and relative risks of colorectal polyps were higher in UC than in CD (aHRs 1.31 vs. 1.06, respectively), with a 20-year cumulative risk differences of 4.4% in UC and 1.5% in CD, corresponding to one extra polyp in 23 patients with UC and one in 67 CD patients during the first 20 years after IBD diagnosis.CONCLUSIONS: In this nationwide population-based study, there was an increased risk of neoplastic colorectal polyps in IBD patients. Colonoscopic surveillance in IBD appears important, especially in UC and after 10 years of disease.

- Background and Aims: The association between microscopic colitis [MC] and cancer risk is unclear. Large, population-based studies are lacking.Methods: We conducted a nationwide cohort study of 11 758 patients with incident MC [diagnosed 1990-2016 in Sweden], 50 828 matched reference individuals, and 11 614 siblings to MC patients. Data were obtained through Sweden's pathology departments and from the Swedish Cancer Register. Adjusted hazard ratios [aHRs] were calculated using Cox proportional hazards models.Results: At the end of follow-up [mean: 6.7 years], 1239 [10.5%] of MC patients had received a cancer diagnosis, compared with 4815 [9.5%] of reference individuals (aHR 1.08 [95% confidence interval1.02-1.16]). The risk of cancer was highest during the first year of follow up. The absolute excess risks for cancer at 5, 10, and 20 years after MC diagnosis were + 1.0% (95% confidence interval [C1]0.4%-1.6%), +1.5% [0.4%-2.6%], and + 3.7% [-2.3-9.6%], respectively, equivalent to one extra cancer event in every 55 individuals with MC followed for 10 years. MC was associated with an increased risk of lymphoma (aHR 1.43 [1.06-1.92]) and lung cancer (aHR 1.32 [1.04-1.68]) but with decreased risks of colorectal (aHR 0.52 [0.40-0.66]) and gastrointestinal cancers (aHR 0.72 [0.60-0.85]). We found no association with breast or bladder cancer. Using siblings as reference group to minimise the impact of shared genetic and early environmental factors, patients with MC were still at an increased risk of cancer (HR 1.20 [1.06-1.36]).Conclusions: This nationwide cohort study demonstrated an 8% increased risk of cancer in MC patients. The risk was highest during the first year of follow-up.

- Objectives: To assess the incidence of biopsy-verified coeliac disease (CD) in Sweden and examine the incidence of duodenal/jejunal biopsies with normal mucosa over time as a proxy for CD awareness and investigation.Design: Nationwide population-based cohort study 1990-2015 based on biopsy reports indicating villous atrophy (VA) or normal mucosa in the duodenum/jejunum.Results: We identified 44 771 individuals (63% females) with a biopsy report specifying VA and 412 279 (62% females) with a biopsy report indicating normal mucosa (without a prior biopsy indicating VA). The median age at diagnosis of CD was 28 years. The mean age-standardised incidence rate during the study period was 19.0 per 100 000 person-years (95% CI 17.3 to 20.8). The incidence reached a peak in 1994 for both sexes and a second higher peak in 2002-2003 for females and in 2006 for males. The lifetime risk of developing CD was 1.8% (2.3% in females and 1.4% in males). Prior to 2015, there was a parallel rise in rates for biopsies showing normal duodenal/jejunal mucosa.Conclusions: In Sweden, the incidence of CD increased until 2002-2003 in females and until 2006 in males. Since then, the incidence of CD has declined despite increasing duodenal/jejunal biopsies, suggesting that increased awareness and investigation are unlikely to elevate the incidence of the disease in Sweden. Across a lifetime, 1 in 44 females and 1 in 72 males are expected to be diagnosed with CD in Sweden, indicating a relatively high societal burden of disease.

- Background: Eosinophilic gastrointestinal disorders (EGIDs) include inflammatory conditions with enteric infiltration of eosinophils and resulting symptoms. This study aims to examine a population-based sample of patients for prevalence, mortality, and cancer risk in EGIDs distal to the esophagus.Methods: Nationwide, population-based cohort study. EGID was identified through relevant biopsy codes from Sweden's all 28 pathology departments through the ESPRESSO cohort. Individuals with EGID were then matched to general population reference individuals with similar age and sex. Study participants were linked to Swedish healthcare registers. Through Cox regression, we calculated adjusted hazard ratios (aHRs) adjusting for sex, age, county, calendar period, and education.Results: In total, 2429 patients (56% female) were found to have EGID distal to the esophagus, representing a prevalence of about 1/4800 in the Swedish population. Mean age was 44 years with 11% children at the time of diagnosis. Mortality was increased 17% in patients with EGIDs compared to reference individuals (aHR = 1.17; 95%CI = 1.04-1.33). Excess mortality was seen in gastric and small bowel eosinophilic disease, but not colonic disease (aHR = 1.81; 95%CI = 1.32-2.48, aHR = 1.50; 95%CI = 1.18-1.89, and aHR = 0.99; 95%CI = 0.85-1.16, respectively). Cause specific mortality was driven by cancer-related death (aHR = 1.33; 95%CI = 1.05-1.69). However, this study failed to show an increase in incident cancers (aHR = 1.14; 95%CI = 0.96-1.35). Comparison of EGID individuals with their siblings yielded similar aHRs.Conclusions: This study found an increased risk of death in patients with EGIDs distal to the esophagus, with cancer death driving the increase. Proximal gut disease seems to confer the greatest risk. There was no increase in incident cancers.

Tidskriftsartikel (refereegranskat)abstract
- Purpose Depression and anxiety afflict millions worldwide causing considerable disability. MULTI-PSYCH is a longitudinal cohort of genotyped and phenotyped individuals with depression or anxiety disorders who have undergone highly structured internet-based cognitive-behaviour therapy (ICBT). The overarching purpose of MULTI-PSYCH is to improve risk stratification, outcome prediction and secondary preventive interventions. MULTI-PSYCH is a precision medicine initiative that combines clinical, genetic and nationwide register data.Participants MULTI-PSYCH includes 2668 clinically well-characterised adults with major depressive disorder (MDD) (n=1300), social anxiety disorder (n=640) or panic disorder (n=728) assessed before, during and after 12 weeks of ICBT at the internet psychiatry clinic in Stockholm, Sweden. All patients have been blood sampled and genotyped. Clinical and genetic data have been linked to several Swedish registers containing a wide range of variables from patient birth up to 10 years after the end of ICBT. These variable types include perinatal complications, school grades, psychiatric and somatic comorbidity, dispensed medications, medical interventions and diagnoses, healthcare and social benefits, demographics, income and more. Long-term follow-up data will be collected through 2029.Findings to date Initial uses of MULTI-PSYCH include the discovery of an association between PRS for autism spectrum disorder and response to ICBT, the development of a machine learning model for baseline prediction of remission status after ICBT in MDD and data contributions to genome wide association studies for ICBT outcome. Other projects have been launched or are in the planning phase.Future plans The MULTI-PSYCH cohort provides a unique infrastructure to study not only predictors or short-term treatment outcomes, but also longer term medical and socioeconomic outcomes in patients treated with ICBT for depression or anxiety. MULTI-PSYCH is well positioned for research collaboration.

- Introduction: There are limited population cohort data on overall and cause-specific mortality in colonic diverticular disease.Objective: To measure overall and cause-specific mortality in colonic diverticular disease, compared to matched reference individuals and siblings.Methods: Population-based cohort study ("the ESPRESSO study") in Sweden. There were 97,850 cases with a medical diagnosis of diverticular disease (defined by international classification of disease codes) and colorectal histology identified in 1987-2017 from histopathology reports. The mortality risk between individuals with colonic diverticular disease and matched reference individuals ( n = 453/634) from the general population was determined. Cox regression models adjusted for comorbidity estimated hazard ratios (HRs) for all-cause mortality.

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: Epidemiological studies have shown inconsistent incidence rates (IRs) for inflammatory bowel disease (IBD).AIM: To assess the incidence and temporal trends of IBD in Sweden.METHODS: Nationwide cohort study based on diagnostic codes for IBD and biopsy reports registered through the ESPRESSO cohort in 1990-2014. Age-specific and age-standardised IRs and cumulative incidence were calculated.RESULTS: Overall, we identified 65 908 cases of incident IBD: ulcerative colitis (UC, n = 38 261, 58%), Crohn's disease (CD, n = 18 577, 28%) and IBD-U (n = 9070, 14%). During 1990-2014, the overall IRs per 100 000 person-years were 29.0 (95% CI: 27.3-30.7) for IBD, 16.9 (15.9-17.9) for UC, and 8.1 (7.7-8.6) for CD. For IBD-U, the IR was 5.2 (4.9-5.6) in 2002-2014. The annual incidence of IBD, UC and CD increased by approximately 7% per year between 1990 and 2001 (P < 0.001) and then decreased by 1%-2% per year from 2002 onwards (P < 0.001). IRs for IBD, UC and IBD-U were higher in males while the IR for CD was higher in females. The lifetime risk of IBD was about 2.5% for both sexes.CONCLUSIONS: In Sweden, the incidence of IBD in all subtypes increased in 1990-2001 but has since declined. One in 40 individuals is expected to be diagnosed with IBD during their lifetime.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background: Eosinophilic esophagitis (EoE) is a chronic inflammatory condition of the esophagus associated with dysphagia and esophageal fibrosis. The incidence of EoE is not precisely known, and significant heterogeneity in study design and disease definition have led to widely variable estimates. Through the ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) study we performed a nationwide population-based study to estimate the incidence and temporal patterns of biopsy-verified EoE.Methods: Between October 2015 and April 2017, we contacted all pathology departments in Sweden (n = 28) to obtain biopsy report data on EoE. To assure a high degree of completeness, we restricted the study to 2004-2015. We then calculated age-specific and age-standardized incidence rates.Results: We identified 1412 incident EoE cases between 2004-2015. The overall age-standardized incidence rates of EoE in Sweden was 1.22 per 100,000 person-years. During the study period, there was a significant increase of 33% [95%CI = 31-36%] (P < 0.001) per year in EoE incidence, and in the last 3 years of follow-up (2013-2015) the incidence was 2.79 per 100,000 person-years. This corresponds to a lifetime risk of biopsy-verified EoE for men of 0.33% (1 in 295 men) and for women 0.12% (1 in 813 women). We observed an early peak of EoE disgnosed at age 15-19 years for both males and females, and a second peak in the late 30 s for males, and early 40 s for females. We noted a 3:1 male-to-female predominance, which did not significantly vary over time.Conclusions: EoE seems to be increasing in Sweden, with an overall age-standardized incidence of EoE of 1.22 per 100,000 person-years in the last decade.
