RESUMO
INTRODUCTION: Microscopic colitis (MC) is an inflammatory condition of the large intestine. Primarily diagnosed in middle-aged and older adults, the incidence of the disease has increased markedly during the past few decades. While MC is associated with a reduced quality of life, large-scale studies on the association with future psychiatric disorders are lacking. METHODS: We conducted a nationwide matched cohort study in Sweden from 2006 to 2021. Through a nationwide histopathology database (the Epidemiology Strengthened by histoPathology Reports in Sweden study), we identified 5,816 patients with a colorectal biopsy consistent with MC. These patients were matched with 21,509 reference individuals from the general population all of whom with no previous record of psychiatric disorders. RESULTS: From 2006 to 2021, 519 patients with MC (median age 64.4 years [interquartile range = 49.5-73.3]) and 1,313 reference individuals were diagnosed with psychiatric disorders (9.9 vs 6.5 events per 1,000 person-years), corresponding to 1 extra case of psychiatric disorder in 29 patients with MC over 10 years. After adjustments, the hazard ratio for psychiatric disorders was 1.57 (95% confidence interval = 1.42-1.74). We found significantly elevated estimates up to 10 years after MC diagnosis and a trend toward higher risk with increasing age. Specifically, we observed increased risks for unipolar depression, anxiety disorders, stress-related disorders, substance abuse, and suicide attempts. In sibling-controlled analysis, the adjusted hazard ratio was 1.76 (95% confidence interval = 1.44-2.15). DISCUSSION: Patients with MC are at increased risk of incident psychiatric disorders compared with the general population.
RESUMO
OBJECTIVES: Despite a suggested link between inflammatory bowel disease (IBD) and myocarditis, the association has not been well-established. This study aimed to investigate the long-term risk of myocarditis in patients with IBD. METHODS: This nationwide cohort involved all patients with biopsy-confirmed IBD in Sweden (1969-2017) (n=83,264, Crohn's disease [CD, n=24,738], ulcerative colitis [UC, n=46,409], and IBD-unclassified [IBD-U, n=12,117]), general population reference individuals (n=391,344), and IBD-free full siblings (n=96,149), and followed until 2019. Primary outcome was incident myocarditis and secondary outcome was severe myocarditis (complicated with heart failure, death, or readmission). Flexible parametric survival models were used to estimate adjusted hazard ratios (aHR) and cumulative incidence of outcomes, along with 95% confidence intervals (CIs). RESULTS: During a median follow-up of 12 years, there were 256 myocarditis cases in IBD patients (incidence rate [IR]=22.6/100,000 person-years) and 710 in reference individuals (IR=12.9), with an aHR of 1.55 (95%CI: 1.33 to 1.81). The increased risk persisted through 20 years after IBD diagnosis, corresponding to one extra myocarditis case in 735 IBD patients until then. This increased risk was observed in CD (aHR=1.48 [1.11 to 1.97]) and UC (aHR=1.58 [1.30 to 1.93]). IBD was also associated with severe myocarditis (IR: 10.1 vs. 3.5; aHR=2.44 [1.89 to 3.15]), irrespective of IBD subtypes (CD: aHR=2.39 [1.43 to 4.01], UC: aHR=2.82 [1.99 to 4.00], and IBD-U: aHR=3.14 [1.55 to 6.33]). Sibling comparison analyses yielded similar results. CONCLUSIONS: Patients with IBD had an increased risk of myocarditis, especially severe myocarditis, for ≥20 years after diagnosis, but absolute risks were low.
RESUMO
BACKGROUND: Predominantly antibody deficiency (PAD) is associated with noninfectious inflammatory gastrointestinal disease. Population estimates of celiac disease (CeD) risk in those with PAD are limited. OBJECTIVE: To estimate population risk of PAD in individuals with CeD. METHODS: We conducted a nationwide case-control study in Swedish individuals who received a diagnosis of CeD between 1997 and 2017 (n = 34,980), matched to population comparators by age, sex, calendar year, and county. The CeD was confirmed through the Epidemiology Strengthened by histopathology Reports in Sweden study, which provided information on biopsy specimens from each of Sweden's pathology departments. PAD was identified using International Classification of Diseases, 10th Revision coding and categorized according to the International Union of Immunologic Societies. Logistic regression was used to calculate adjusted odds ratios (aORs) and 95% CIs. RESULTS: PAD was more prevalent in CeD than in population controls (n = 105 [0.3%] vs n = 57 [0.033%], respectively). This translated to an aOR of 8.23 (95% CI 5.95-11.48). The association was strongest with common variable immunodeficiency (aOR 17.25; 95% CI 6.86-52.40), and slightly lower in other PAD (aOR 8.39; 95% CI 5.79-12.32). The risk of CeD remained increased at least 5 years after diagnosis of PAD (aOR 4.79; 95% CI 2.89-7.97, P-heterogeneity ≤ 0.001). CONCLUSION: PAD was associated with an increased risk of CeD. A particularly strong association was seen in those with CVID, although this should be interpreted cautiously given the limited understanding of the mechanisms of histopathologic changes in these patients.

BACKGROUND AND AIMS: Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a precursor of pancreatic cancer. While earlier research has shown a high prevalence of synchronous/metachronous extrapancreatic tumors in IPMN patients, these studies have often been small with retrospective data collection. The aim of the study was to examine absolute and relative risks of non-pancreatic gastrointestinal (GI) cancer precursors and mortality in histologically confirmed IPMN. METHODS: Through the nationwide ESPRESSO histopathology cohort, we retrieved data on IPMN between 1965 and 2016. Each index case was matched to ≤5 general population controls. Through Cox regression, we estimated hazard ratios (HRs) for future GI cancer precursors and death. RESULTS: A total of 117 patients with IPMN and 539 age- and sex-matched controls were included. Over a median of 2.1 years of follow up, we confirmed two (1.7%) incident GI cancer precursors in IPMN vs. four (0.7%) in controls, corresponding to an HR of 1.89 (95%CI = 0.34-10.55). By contrast, IPMN patients were at increased risk of death (HR 3.61 (95%CI = 1.79-7.27)). The most common cause of death in IPMN was pancreatic cancer (n = 14; 45.2% of all deaths). CONCLUSIONS: We found no association between IPMN and other GI cancer precursors. This argues against comprehensive routine surveillance for other GI cancer precursors in IPMN patients. Mortality was increased in IPMN with pancreatic cancer being the most common cause of death, indicating the need for lifelong follow up in all resected and non-resected patients with IPMN. However, results should be confirmed in larger cohorts.

BACKGROUND: Inflammatory diseases have been associated with an increased cardiovascular risk. However, data on incident major adverse cardiovascular events (MACE) from large population-based cohorts of patients with eosinophilic esophagitis (EoE) is lacking. METHODS: This study included all Swedish adults with EoE without a record of previous cardiovascular disease (CVD) (1990-2017, N = 1546) with follow-up until 2019. Individuals with EoE were identified from prospectively recorded histopathology reports from all Swedish pathology departments (n = 28). EoE patients were matched at index date for age, sex, calendar year and county with up to five general population reference individuals (N = 7281) without EoE or CVD. Multivariable-adjusted hazard ratios (aHRs) for MACE (ischemic heart disease, congestive heart failure, stroke and cardiovascular mortality) were calculated using Cox proportional hazards models. Full sibling comparisons and adjustment for cardiovascular medication were performed. RESULTS: During a median follow-up of 6.0 years, we observed 65 incident MACE in patients with EoE (6.4/1000 person-years (PY)) and 225 in reference individuals (4.7/1000 PY). EoE was not associated with a higher risk of MACE (aHR = 1.14, 95% CI = 0.86-1.51) or any of its components. No differences between age, sex and follow-up time were observed. The results remained stable in sensitivity analyses, including when adjusting for relevant cardiovascular medications and a full sibling comparison. CONCLUSIONS: In this large population-based cohort study, patients with EoE had no increased risk of MACE compared to reference individuals and full siblings. The results are reassuring for patients with EoE.

Background: Microscopic colitis (MC) has been associated with several immune-mediated diseases including psoriasis, but earlier research has been limited to psoriasis occurring before MC. Data from large-scale cohort studies investigating MC and risk of future psoriasis are lacking. Objective: To examine the association between MC and psoriasis. Methods: In a nationwide, population-based, matched cohort study in Sweden from 2007 to 2021, we identified 8404 patients with biopsy-verified MC (diagnosed in 2007-2017), 37,033 matched reference individuals, and 8381 siblings without MC. Information on MC was obtained through the ESPRESSO cohort (a Swedish histopathology database with nationwide coverage). Using Cox regression, we calculated hazard ratios (HRs) and 95% confidence intervals (CIs) for psoriasis up until 2021. Results: During a median follow-up of 9.2 years (interquartile range = 6.7-11.7), 179 MC patients and 440 reference individuals were diagnosed with psoriasis (241.1 vs 131.8 events per 100,000 person-years), corresponding to one extra case of psoriasis in 91 patients with MC over 10 years. After adjustment for the matching variables (birth year, sex, county of residence, and calendar period) and level of education, we computed an adjusted hazard ratio (aHR) of 1.82 (95% CI = 1.53-2.17). Stratified by sex, estimates were similar and when examining the aHR across different lengths of follow-up, we found significantly elevated estimates up to 10 years after MC diagnosis. Compared to MC-free siblings, the aHR was 1.85 (95% CI = 1.36-2.51). Conclusion: Patients with MC are at an almost doubled risk of psoriasis compared to the general population. Clinicians need to consider psoriasis in MC patients with skin lesions.
RESUMO
Background: Celiac disease (CeD) is associated with several immune-mediated disorders, but it is unclear whether it is associated with eosinophilic esophagitis (EoE). Objective: We sought to examine the risk of EoE in patients with biopsy-verified CeD compared with matched controls and siblings. Methods: Using nationwide population-based histopathology data, we identified 27,338 patients with CeD diagnosed in the period 2002 to 2017 in Sweden. Patients with CeD were age- and sex-matched with up to 5 reference individuals (n = 134,987) from the general population. Cox Regression was used to estimate hazard ratios (HRs) for developing biopsy-verified EoE. In a secondary analysis, we used unaffected siblings of patients with CeD as comparators to adjust for intrafamilial confounding. Results: The median age at CeD diagnosis was 27 years, and 63.3% were female patients. During a median follow-up of 8.1 years, 17 patients with CeD and 13 matched reference individuals were diagnosed with EoE. This corresponded to incidence rates of 0.08 versus 0.01 per 1000 person-years, respectively, and an adjusted HR for EoE of 6.65 (95% CI, 3.26-13.81). Compared with their siblings without CeD, patients with CeD were however at a no increased risk of EoE (HR, 1.39; 95% CI, 0.55-3.51). Conclusions: In this study, individuals with CeD were at a 6.6-fold increased risk of later EoE compared with the general population. This association might be explained by an altered health-seeking behavior or through shared genetic or early environmental factors because the excess risk disappeared in sibling analyses.
RESUMO
Introduction: Eosinophilic esophagitis (EoE) is a chronic, allergic inflammatory disease of the esophagus. It has a peak incidence in the 2nd and 3rd decades of life. Despite this, little is known about pregnancy outcomes in patients with EoE. Methods: Using a validated histopathologic and nationwide population-based cohort for the diagnosis of EoE, we examined maternal and fetal outcomes, with preterm birth as the primary outcome, in females with EoE compared to matched controls. Odds ratios (ORs) were calculated using logistic regression. Results: Between 1992 and 2016, we identified 19 females with EoE who gave birth to 23 children (reference births: n = 115). There was 1 (4.3%) preterm birth in the EoE cohort versus 8 (7.0%) in the reference cohort (OR = 0.60; 95% CI = 0.07-5.14). Secondary fetal outcomes included stillbirth, neonatal death, small for gestational age, low birth weight (LBW), and low Apgar score. Of these, LBW (<2,500 g) in patients with EoE compared to controls correlated to an OR of 12.42 (95% CI = 1.26-122.42); however, this finding was based on very low numbers. The remaining fetal outcomes were not significantly different between females with EoE and controls. Secondary pregnancy and maternal outcomes including induction of labor, instrumental delivery, gestational diabetes, or pre-eclampsia were not significantly different between patients with EoE and controls. Discussion/Conclusion: Overall in this nationwide cohort study, we did not find increased association of preterm birth in patients with EoE.
