- BACKGROUND AND AIMS: Although dermatitis herpetiformis is closely associated with celiac disease (CD), data on the relationship between CD and other dermatologic disorders have been mixed. We aimed to quantify the risk of skin disorders in patients after CD diagnosis in a population-based setting.METHODS: Using data from all 28 pathology departments in Sweden 1969-2016, we identified patients with CD. Each patient was matched by age, sex, calendar year, and geographic region to up to 5 population controls. We calculated the risk of any skin disease and specific skin diseases using Cox proportional hazards.RESULTS: We identified 43,300 patients with CD and 198,532 matched controls. After a median follow-up time of 11.4 years, the incidences of skin disease in CD patients and controls were 22.6 and 14.8 per 1000 person-years respectively (HR=1.55; 95%CI 1.51-1.58). Increased risks were present for eczema (HR=1.67; 95%CI 1.56-1.79), psoriasis (HR=1.55; 95%CI 1.43-1.68), urticaria (HR=1.52; 95% CI 1.42-1.64), vitiligo (HR=1.90; 95%CI 1.52-2.39), acne (HR=1.39; 95%CI 1.29-1.50), and alopecia areata (HR=1.78; 95%CI 1.43-2.20).CONCLUSIONS: Compared to the general population, patients with CD are at increased risk of multiple common skin disorders, a risk that persists in the long-term.

Borrelia infection and risk of celiac disease
- 2017

Ingår i: BMC Medicine. - : BioMed Central. - 1741-7015. ; 15

Tidskriftsartikel (refereegranskat)abstract
- Background: Environmental factors, including infectious agents, are speculated to play a role in the rising prevalence and the geographic distribution of celiac disease, an autoimmune disorder. In the USA and Sweden where the regional variation in the frequency of celiac disease has been studied, a similarity with the geographic distribution of Lyme disease, an emerging multisystemic infection caused by Borrelia burgdorferi spirochetes, has been found, thus raising the possibility of a link. We aimed to determine if infection with Borrelia contributes to an increased risk of celiac disease.Methods: Biopsy reports from all of Sweden's pathology departments were used to identify 15,769 individuals with celiac disease. Through linkage to the nationwide Patient Register, we compared the rate of earlier occurrence of Lyme disease in the patients with celiac disease to that in 78,331 matched controls. To further assess the temporal relationship between Borrelia infection and celiac disease, we also examined the risk of subsequent Lyme disease in patients with a diagnosis of celiac disease.Results: Twenty-five individuals (0.16%) with celiac disease had a prior diagnosis of Lyme disease, whereas 79 (0.5%) had a subsequent diagnosis of Lyme disease. A modest association between Lyme disease and celiac disease was seen both before (odds ratio, 1.61; 95% confidence interval (CI), 1.06-2.47) and after the diagnosis of celiac disease (hazard ratio, 1.82; 95% CI, 1.40-2.35), with the risk of disease being highest in the first year of follow-up.Conclusions: Only a minor fraction of the celiac disease patient population had a prior diagnosis of Lyme disease. The similar association between Lyme disease and celiac disease both before and after the diagnosis of celiac disease is strongly suggestive of surveillance bias as a likely contributor. Taken together, the data indicate that Borrelia infection is not a substantive risk factor in the development of celiac disease.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND & AIMS: Gastrointestinal infections have been associated with later development of inflammatory bowel diseases (IBD). However, studies have produced conflicting results. We performed a nationwide case-control study in Sweden to determine whether gastroenteritis is associated with the development of Crohn's disease (CD) or ulcerative colitis (UC).METHODS: Using the Swedish National Patient Register, we identified 44,214 patients with IBD (26,450 with UC; 13,387 with CD; and 4377 with IBD-unclassified) from 2002 to 2014 and matched them with 436,507 individuals in the general population (control subjects). We then identified patients and control subjects with reported episodes of gastroenteritis (from 1964 to 2014) and type of pathogen associated. We collected medical and demographic data and used logistic regression to estimate odds ratios (ORs) for IBD associated with enteric infection.RESULTS: Of the patients with IBD, 3105 (7.0%) (1672 with UC, 1050 with CD, and 383 with IBD-unclassified) had a record of previous gastroenteritis compared with 17,685 control subjects (4.1%). IBD cases had higher odds for an antecedent episode of gastrointestinal infection (aOR, 1.64; 1.57-1.71), bacterial gastrointestinal infection (aOR, 2.02; 1.82-2.24), parasitic gastrointestinal infection (aOR, 1.55; 1.03-2.33), and viral gastrointestinal infection (aOR, 1.55; 1.34-1.79). Patients with UC had higher odds of previous infection with Salmonella, Escherichia coli, Campylobacter, or Clostridium difficile compared to control subjects. Patients with CD had higher odds of previous infection with Salmonella, Campylobacter, Yersinia enterocolitica, C difficile, amoeba, or norovirus compared to control subjects. Increasing numbers of gastroenteritis episodes were associated with increased odds of IBD, and a previous episode of gastroenteritis remained associated with odds for IBD more than 10 years later (aOR, 1.26; 1.19-1.33).CONCLUSIONS: In an analysis of the Swedish National Patient Register, we found previous episodes of gastroenteritis to increase odds of later development of IBD. Although we cannot formally exclude misclassification bias, enteric infections might induce microbial dysbiosis that contributes to the development of IBD in susceptible individuals.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Celiac disease (CD) is an immune‐mediated disease triggered by gluten intake and affects around 1% of the population worldwide. Although patients with CD have an increased use of healthcare, data on work disability remains scarce. To estimate work loss in patients with CD before and after diagnosis. We identified 16,005 working‐age patients with prevalent CD, and 4,936 incident working‐age patients diagnosed in 2008‐2015 through biopsy reports from Sweden’s 28 pathology departments. CD was defined by presence of villus atrophy (Marsh 3) on biopsy (gold standard). Each patient was compared to up to 5 matched general‐population comparators. Using nationwide social insurance registers, we retrieved prospectively‐recorded data on compensation for sick leave and disability. In 2015, patients with prevalent CD had a mean of 42.5 (95%CI: 40.9‐44.1) lost work days as compared with 28.6 (27.9‐29.2) in the general‐population comparators, corresponding to a relative difference of 49%. Among incident patients, the annual mean difference between patients and comparators was 8.0 (5.4‐10.6) lost work days 5 years before CD diagnosis, which grew to 13.7 (9.1‐18.3) days 5 years after diagnosis. In addition to the continuously increasing mean difference in lost work days over time, there was also a transient increase in work loss in patients with CD during the year of diagnosis (mean difference: 15.6 days, 95%CI: 13.1‐18.0). Patients with CD miss more work days than comparators before their diagnosis, and this loss increases and persists after diagnosis despite presumed installation of treatment with gluten‐free diet.

- BACKGROUND: Celiac disease (CD) affects around 1% of the population worldwide. Data on work disability in celiac patients remain scarce. We estimated work loss in celiac patients including its temporal relationship to diagnosis.METHODS: Through biopsy reports from Sweden's 28 pathology departments, we identified 16,005 working-aged patients with prevalent CD (villus atrophy) as of January 1, 2015, and 4,936 incident patients diagnosed with CD in 2008-2015. Each patient was matched to up to 5 general-population comparators. Using nationwide social insurance registers, we retrieved prospectively-recorded data on compensation for sick leave and disability leave to assess work loss in patients and comparators.RESULTS: In 2015, patients with prevalent CD had a mean of 42.5 lost work days as compared with 28.6 in comparators (mean difference: 14.7, 95%CI: 13.2-16.2), corresponding to a relative increase of 49%. More than half of the work loss (60.1%) in celiac patients was derived from a small subgroup (7%) while 75.4% had no work loss. Among incident patients, the annual mean difference between patients and comparators was 8.0 (5.4-10.6) lost work days 5 years before CD diagnosis, which grew to 13.7 (9.1-18.3) days 5 years after diagnosis. No difference in work loss was observed between patients with or without mucosal healing at follow-up.CONCLUSIONS: Celiac patients lost more work days than comparators before their diagnosis, and this loss increased after diagnosis. Identifying patients with an increased risk of work loss may serve as a target to mitigate work disability, and thereby reduce work loss, in CD.

- The female predominance in celiac disease is difficult to explain because population-based screening studies reveal similar rates for celiac disease-specific autoantibodies in males and females. The aim of this study was to explore the role of age and gender in the presentation of celiac disease. The frequency of presentation according to age, gender and mode of presentation was determined by analysis of a prospectively maintained database of children and adults seen at a tertiary medical center. Of 1,682 patients (68 % female) aged 3 months to 86 years who were diagnosed with celiac disease, age at diagnosis in females peaked at 40-45 years, whereas the age at diagnosis for males had two peaks: 10-15 and 35-40 years. A significantly lower percentage of males in early adulthood were diagnosed compared with males in all other age groups (P < 0.0001). The young and elderly had a more even gender distribution. Based on our analysis, males are diagnosed with celiac disease less frequently than females, especially in early adulthood. There should be more emphasis on the diagnosis of celiac disease among young adult males.

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: Coeliac disease has been associated with an increased risk of cardiovascular disease in some studies, whereas other studies have shown no association. We performed a systematic review and meta-analysis of cardiovascular disease in celiac disease. Methods: Pubmed, Cinahl, EMBASE and Medline via Ovid were searched for relevant articles published until January 5, 2015. English-language articles on studies with more than 20 patients were included, and were quality rated using the GRADE risk of bias tool. We used random-effects models and assessed heterogeneity using the I-2 statistic. Results: Ten studies were relevant, reporting the risk of myocardial infarction, cardiovascular death and stroke in 33,128/32,903/32,466 coeliac disease patients respectively. Only one study examined celiac disease and a composite measure of cardiovascular disease and this study found a hazard ratio of 1.10 (95% CI 1.03-1.28). In a meta-analysis, we observed an increased risk of stroke (OR 1.11; 95% CI 1.02-1.20). The risks of myocardial infarction (OR 1.12; 95% CI 0.83-1.40) and cardiovascular death (OR 1.12; 95% CI 0.96-1.29) were similar but were estimated with less certainty. Heterogeneity was low for all outcomes except for myocardial infarction where it was moderate. Conclusion: Coeliac disease was associated with a modestly increased risk of cardiovascular disease, but the evidence base is limited.

- Background: Patients with celiac disease (CD) are at increased risk of certain infections, but it is unknown if mucosal healing influences this risk.Methods: We collected data on 29,096 individuals with CD (equal to villous atrophy) through Sweden's 28 pathology departments undergoing biopsy 1969-2008. Through the Swedish Patient Register we obtained information on any infection and specifically sepsis, streptococcal infection, influenza, Clostridium difficile, herpes zoster and pneumococcal infection up until December 2009. We used Cox regression to calculate hazard ratios (HRs) for the risk of future diagnosis of infection according to mucosal healing on follow-up biopsy (persistent villous atrophy vs mucosal healing).Results: Of 5598 CD individuals with no record of any infections before follow-up biopsy, 45% had persistent villous atrophy, 619 (24%) of them had a later infection, compared to 579 (19%) in those with mucosal healing (p<0.01); the yearly incidence was 2.1% in both groups. Adjusting for age, sex, calendar period, time between biopsies and education, persistent villous atrophy was however not associated with later infection overall (HR=0.99; 95% CI=0.88-1.11) or with any of the specific infections.Conclusions: In CD, mucosal healing does not influence the risk of serious infection requiring hospital-based medical attention.

- BACKGROUND & AIMS: The incidence of small bowel cancers is increasing. Associations have been made between celiac disease (CD) and small bowel cancers, but there have been no detailed studies of large cohorts.METHODS: Through the nationwide Epidemiology Strengthened by Histopathology Reports in Sweden cohort study, we retrieved data from Sweden's 28 pathology departments on all individuals who received a diagnosis of CD from 1965 through 2017. Individuals with CD, defined as duodenal or jejunal villous atrophy (stage 3 Marsh score), were matched with as many as 5 randomly selected reference individuals from the general population. We used stratified Cox regression to calculate hazard ratios (HRs) for small bowel adenocarcinoma, adenomas, and carcinoids.RESULTS: During a median follow-up of 11 years, we identified 48,119 individuals with CD (patients) and 239,249 reference individuals. Beginning at 1 year after a diagnosis of CD, 29 patients (0.06%) received a diagnosis of small bowel adenocarcinoma vs 45 reference individuals (0.02%), 7 patients received a diagnosis of carcinoids vs 31 reference individuals, and 48 patients received a diagnosis of adenomas vs 50 reference individuals. Corresponding HRs were small bowel adenocarcinoma 3.05 (95% confidence interval [CI], 1.86-4.99), carcinoids 0.59 (95% CI, 0.16-2.10), and adenomas 5.73 (95% CI, 3.70-8.88). HRs were independent of sex and age. Overall, there was 1 extra case of small bowel adenocarcinoma in every 2944 patients with CD followed for 10 years. There was an inverse association between mucosal healing risk of future small bowel adenocarcinoma (HR, 0.18; 95% CI, 0.02-1.61), although the HR failed to attain statistical significance.CONCLUSIONS: In an analysis of a nationwide pathology database in Sweden, we found the absolute risk of small bowel adenocarcinoma is low in individuals with CD. However, risks of small bowel adenocarcinoma and adenomas (but not carcinoids) are significantly increased in people with CD compared to people without this disease.

- Purpose: To determine the prevalence of celiac disease in infertile women.Methods: A systematic search of four databases was conducted up until February 6, 2020. The search terms "c(o)eliac disease", "gluten", "vill(o)us atrophy", "infertility" and "subfertility" yielded 1142 unique hits. Articles in other languages than English, conference abstracts, letters, and publications where relevant information was missing were excluded. In our main analysis, celiac disease had to be verified by duodenal biopsy. The titles and abstracts, and the full-text articles were independently reviewed by two researchers. A fixed-effect model was used to calculate the weighted prevalence.Results: Based on 11 studies (1617 women), the pooled prevalence of biopsy-confirmed celiac disease was 0.7% (95% CI = 0.2%-1.2%) in women with any infertility. Restricting our study population to women with unexplained infertility, the pooled prevalence of biopsy-confirmed celiac disease was 0.6% (95% CI = 0.0%-1.6%). When including studies where celiac disease had been defined per serology (20 studies; 5158 women), the pooled prevalence of celiac disease was 1.1% (95% CI = 0.6%-1.6%) in women with any infertility.Conclusion: Our results indicate that celiac disease is not more common in infertile women than in the general population. Celiac screening in infertile women may have low yield.

- BACKGROUND: Previous studies investigating the prevalence of celiac disease (CD) in individuals with autoimmune hepatitis (AIH) have shown highly variable results. We therefore aimed to examine the prevalence of CD in individuals with AIH.METHODS: Two professional librarians searched PubMed, EMBASE, Cochrane and Web of Science Core Collection up until 7 February 2020. The search terms included 'celiac disease', 'celiac', 'transglutaminases', 'gluten', 'gliadin', 'EMA', 'TTG' and 'villous' combined with 'autoimmune', 'hepatitis', 'ANA', 'SMA' and 'LKM'. This search yielded 2419 unique publications. A systematic review based on the PRISMA guidelines resulted in 31 articles eligible for full text review. Fifteen articles were deemed relevant, with 8 being included in our main analysis. A fixed-effect inverse variance-weighted model was used, and heterogeneity was calculated.RESULTS: Our main analysis included 567 individuals with AIH from eight studies, where biopsy-verified CD (equivalent to Marsh III) was seen in 23 individuals (4.1%). The pooled prevalence of CD in AIH was 3.5% (95% CI = 1.6%-5.3%) (heterogeneity: P = .874; I2 = 0.0%), which is clearly higher than the 1% CD seen in most general populations. When also including studies where CD had been diagnosed through positive serology without biopsy (15 studies: n = 1817 individuals with AIH), the pooled prevalence of CD was 2.9% (95% CI = 2.1%-3.8%) (heterogeneity: P < .001; I2 = 66.8%).CONCLUSION: Our results demonstrate a higher prevalence of CD in individuals with AIH compared to the general population. CD screening may be considered in patients with AIH.

Forskningsöversikt (refereegranskat)abstract
- OBJECTIVES: To conduct a systematic review and meta-analysis that defines the worldwide incidence of celiac disease (CD) and examines temporal trends.METHODS: MEDLINE and EMBASE were searched for population-based studies reporting the incidence of CD in the overall population, children, or adults. No limits were placed on year or language of publication. Studies solely examining at-risk populations (e.g., patients with type 1 diabetes) were excluded. Random-effects models were performed to meta-analyze sex- and age-specific incidence in the 21st century. Temporal trend analyses assessed the average annual percent change in CD incidence over time.RESULTS: Of 11,189 citations, 86 eligible studies were identified for inclusion, of which 50 were deemed suitable for analyses. In the 21st century, the pooled female incidence of CD was 17.4 (95% confidence interval [CI]: 13.7, 21.1) (I-2= 99.5%) per 100,000 person-years, compared with 7.8 (95% CI: 6.3, 9.2) (I-2= 98.6%) in males. Child-specific incidence was 21.3 per 100,000 person-years (95% CI: 15.9, 26.7) (I-2= 99.7%) compared with 12.9 (95% CI: 7.6, 18.2) (I-2= 99.9%) in adults. Pooling average annual percent changes showed the incidence of CD to be increasing by 7.5% (95% CI: 5.8, 9.3) (I-2= 79.6%) per year over the past several decades.DISCUSSION: Incidence of CD is highest in females and children. Overall, the incidence has been significantly rising in the latter half of the 20th century and into the 21st century throughout the Western world. Population-based studies in Africa, Asia, and Latin America are needed to provide a comprehensive picture of the global incidence of CD.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Earlier research suggests that birth weight may be associated with celiac disease (CD), but the direction of association has been unclear potentially due to confounding effect from genetic and intrafamilial factors. Through within-twin analyses, we aimed to minimize confounding effects such as twins that share genetic and early environmental exposures.Materials and methods: Using the Swedish Twin Registry, we examined the birth weight of 146,830 twins according to the CD status. CD was defined as having villous atrophy according to a small intestinal biopsy reports.Results: The prevalence of diagnosed CD was 0.5% (n=669), and we included 407 discordant pairs of CD-non-CD twins. Comparing the 669 CD patients with non-CD twins, the association between birth weight and future CD was not statistically significant (odds ratio [OR] per 1000 g increase in birth weight: 1.16; 95% confidence interval [CI]=0.97-1.38). In males, the association was positive and statistically significant (OR=1.50; 95% CI=1.11-2.02). However, the association was not significant in within-pair analyses for both dizygotic and monozygotic twins and for both sexes.Conclusion: This population-based study found that in male twins, higher birth weight was associated with higher risk of CD. However, when comparing discordant twin pairs in within-twin pair analyses, there was no statistically significant association between birth weight, intrauterine growth, and future risk of CD.

- Background and objective: Almost 100% individuals with coeliac disease (CD) are carriers of the human leucocyte antigen (HLA) DQ2/DQ8 alleles. Earlier studies have, however, failed to consider the HLA system when estimating heritability in CD, thus violating an underlying assumption of heritability analysis. We examined the heritability of CD in a large population-based sample of twins, considering HLA.Design: In a population-representative sample of 107 912 twins, we identified individuals with CD (equal to villous atrophy) through biopsy reports from all Swedish pathology departments. We calculated concordance rates and tetrachoric correlations for monozygotic (MZ) and dizygotic (DZ) twin pairs. Further, we estimated heritability of CD, first strictly from observed data, and then the non-HLA heritability, representing the heritability of all genetic factors except the HLA locus, using an approach that circumvent the violation of underlying assumptions.Results: We identified 513 twins with a diagnosis of CD (prevalence 0.48%). Concordance rates were higher in MZ pairs (0.49) than in DZ pairs (0.10), as were tetrachoric correlations (0.89 in MZ vs 0.51 in DZ pairs). The heritability of CD was 75% (95% CI 55% to 96%). The non-HLA heritability was slightly attenuated, 68% (95% CI 40% to 96%), with shared (17%) and non-shared (15%) environmental factors explaining the remaining variability of CD.Conclusions: CD is characterised by a high heritability, but our study also suggests that non-shared environmental factors may be of importance to CD development. HLA seems to have only moderate impact on heritability estimates.

- BACKGROUND: Celiac disease (CD) is associated with an increased risk of developing epilepsy, a risk that persists after CD diagnosis. A significant proportion of CD patients have persistent villous atrophy (VA) on follow-up biopsy. This study's objective was to determine whether persistent VA on follow-up biopsy affects long-term epilepsy risk and epilepsy-related hospital emergency admissions.METHODS: Nationwide Cohort Study. We identified all people in Sweden with histological evidence of CD who underwent a follow-up small intestinal biopsy (1969-2008). We compared those with persistent VA to those who showed histological improvement, assessing the development of epilepsy and related emergency hospital admissions (defined according to relevant ICD codes in the Swedish Patient Register). Cox regression analysis was used to assess outcome measures.RESULTS: Of 7590 people with CD who had a follow-up biopsy, VA was present in 43%. The presence of persistent VA was significantly associated with a reduced risk of developing newly-diagnosed epilepsy (hazard ratio [HR] 0.61; 95% confidence interval [CI] 0.38-0.98). On stratified analysis this effect was primarily amongst males (HR 0.35; 95 CI 0.15-0.80). Among the 58 CD patients with a prior diagnosis of epilepsy, those with persistent VA were less likely to visit an emergency department with epilepsy (HR 0.37; 95%CI 0.09-1.09).CONCLUSIONS: In a population-based study of CD individuals, persisting VA on follow up biopsy was associated with reduced future risk of developing epilepsy but did not influence emergency epilepsy-related hospital admissions. Mechanisms as to why persistent VA confers this benefit requires further exploration. This article is protected by copyright. All rights reserved.

- Background: Patients with celiac disease (CD) often have articular complaints, and small prior studies suggest an association with Ehlers-Danlos syndrome (EDS)/joint hypermobility syndrome (JHS). Aims: This study examines the risks of EDS/JHS in patients with CD. Methods: This cohort study compared all individuals in Sweden diagnosed with CD based on small intestinal biopsy between 1969-2008 (n = 28,631) to 139,832 matched reference individuals, and to a second reference group undergoing biopsy without having CD (n = 16,104). Rates of EDS/JHS were determined based on diagnostic codes in the Swedish Patient Register. Hazard ratios (HRs) for EDS/JHS were estimated through Cox regression. Results: There are 45 and 148 cases of EDS/JHS in patients with CD and reference individuals, respectively. This corresponds to a 49% increased risk of EDS/JHS in CD (95% CI = 1.07-2.07). The HR for EDS was 2.43 (95% CI = 1.20-4.91) and for JHS 1.34 (95% CI = 0.93-1.95). Compared to reference individuals undergoing intestinal biopsy, CD was not a risk factor for EDS/JHS. A stronger association was seen in patients initially diagnosed with EDS/JHS and subsequently diagnosed with CD (odds ratio = 2.29; 95% CI = 1.21-4.34). Conclusions: Individuals with CD have higher risk of EDS/JHS than the general population, which may be due to surveillance bias or factors intrinsic to celiac development.

- In a systematic review and meta-analysis, we found risk of major GI bleeding to be similar between NOACs and conventional anticoagulation. Dabigatran and rivaroxaban, however, may be associated with increased odds of major GI bleeding. Further high-quality studies are needed to characterize GI bleeding risk among NOACs.

- Question: Is celiac disease associated with increased mortality?Findings: In this population-based cohort study of 49 & x202f;829 patients in Sweden with celiac disease followed up for a median of 12.5 years, the mortality rate compared with general population controls was 9.7 vs 8.6 deaths per 1000 person-years, a difference that was statistically significant.Meaning: In a Swedish population, celiac disease was associated with a small but statistically significant increased mortality risk.Importance: Celiac disease may be associated with a modest but persistent increased long-term mortality risk. It is uncertain whether this risk has changed in the era of wider diagnosis rates, less severe clinical disease, and more widespread availability of gluten-free food.Objective: To evaluate the association between celiac disease and mortality risk in a population-based cohort in Sweden.Design, Setting, and Participants: All individuals in Sweden with celiac disease diagnosed between 1969 and 2017 were identified through the Epidemiology Strengthened by histoPathology Reports in Sweden (ESPRESSO) cohort. Participants (n = 49 & x202f;829) were observed starting on the day of the biopsy. The final date of follow-up was December 31, 2017.Exposures: Celiac disease was defined by the presence of small intestinal villus atrophy on histopathology specimens during the years 1969-2017 from Sweden's 28 pathology departments. Each individual was matched with as many as 5 control participants in the general population by age, sex, county, and calendar period.Main Outcomes and Measures: The primary outcome was all-cause mortality, and the secondary outcome was cause-specific mortality. Patients with celiac disease were compared with controls using stratified Cox proportional modeling, stratifying by year of diagnosis.Results: There were 49 & x202f;829 patients with celiac disease, including 24% who were diagnosed between the years 2010 and 2017. The mean (SD) age at diagnosis was 32.2 (25.2) years and 62.4% were women. During a median follow-up time of 12.5 years, 13.2% (n = 6596) died. Compared with controls (n = 246 & x202f;426), overall mortality was increased in those with celiac disease (9.7 vs 8.6 deaths per 1000 person-years; absolute difference, 1.2 per 1000 person-years; hazard ratio [HR], 1.21 [95% CI, 1.17-1.25]). The relative increase in mortality risk was present in all age groups and was greatest in those diagnosed in the age range of 18 to 39 years (1.9 vs 1.1 per 1000 person-years; HR, 1.69 [95% CI, 1.47-1.94]; P values for heterogeneity comparing 18-39 years with 40-59 years and with >= 60 years were both <.001). Individuals with celiac disease were at increased risk of death from cardiovascular disease (3.5 vs 3.4 per 1000 person-years; HR, 1.08 [95% CI, 1.02-1.13]), cancer (2.7 vs 2.2 per 1000 person-years; HR, 1.29 [95% CI, 1.22-1.36]), and respiratory disease (0.6 vs 0.5 per 1000 person-years; HR, 1.21 [95% CI, 1.08-1.37]). When compared with controls, the overall mortality risk was greatest in the first year after diagnosis (15.3 vs 6.5 per 1000 person-years; HR, 2.34 [95% CI, 2.14-2.55]) but persisted beyond 10 years after diagnosis (10.5 vs 10.1 per 1000 person-years; HR, 1.15 [95% CI, 1.10-1.20]). The mortality risk was likewise present for patients diagnosed during the years 2010-2017 (7.5 vs 5.5 per 1000 person-years; HR, 1.35 [95% CI, 1.21-1.51]).Conclusions and Relevance: In a Swedish population studied between 1969 and 2017, a diagnosis of celiac disease compared with the general population was associated with a small but statistically significant increased mortality risk. This population epidemiology study used Swedish histopathology registry data to estimate mortality risk in patients with vs without celiac disease.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Celiac disease (CD) is associated with increased mortality, in part due to cancer. Most studies investigating this cancer risk involved patients diagnosed before widespread increases in CD diagnosis rates and access to gluten-free food. We performed a population-based study of the risk of cancer in CD.METHODS: We identified all patients in Sweden with CD as defined as duodenal villus atrophy, using the ESPRESSO cohort. Each patient was matched to ≤5 controls by age, sex, and county. We used stratified Cox proportional-hazards model, following patients from diagnosis until first cancer, or by December 31, 2016.RESULTS: Among 47,241 patients with CD, 30,080 (64%) were diagnosed since 2000. After a median follow-up of 11.5 years, the incidence of cancer was 6.5 and 5.7 per 1000 person-years in CD patients and controls, respectively. The overall risk of cancer was increased (hazard ratio[HR] 1.11; 95%CI 1.07-1.15), but was only significantly elevated in the first year after CD diagnosis (HR 2.47; 95%CI 2.22-2.74), and not subsequently (HR 1.01; 95%CI 0.97-1.05), though the risks of hematologic, lymphoproliferative, hepatobiliary, and pancreas cancers persisted. The overall risk was highest in those diagnosed with CD after age 60 years (HR 1.22; 95%CI 1.16-1.29) and was not increased in those diagnosed before age 40. The cancer risk was similar among those diagnosed with CD before or after the year 2000.CONCLUSIONS: There is an increased risk of cancer in CD, even in recent years, but this risk increase is confined to those diagnosed with CD after age 40, and is primarily present within the first year of diagnosis.

Celiac disease and non-celiac gluten sensitivity
- 2015

Ingår i: BMJ-BRITISH MEDICAL JOURNAL. - : B M J Group. - 1756-1833. ; 351

Forskningsöversikt (refereegranskat)abstract
- Celiac disease is a multisystem immune based disorder that is triggered by the ingestion of gluten in genetically susceptible individuals. The prevalence of celiac disease has risen in recent decades and is currently about 1% in most Western populations. The reason for this rise is unknown, although environmental factors related to the hygiene hypothesis are suspected. The pathophysiology of celiac disease involves both the innate and adaptive immune response to dietary gluten. Clinical features are diverse and include gastrointestinal symptoms, metabolic bone disease, infertility, and many other manifestations. Although a gluten-free diet is effective in most patients, this diet can be burdensome and can limit quality of life; consequently, non-dietary therapies are at various stages of development. This review also covers non-celiac gluten sensitivity. The pathophysiology of this clinical phenotype is poorly understood, but it is a cause of increasing interest in gluten-free diets in the general population.

- The prevalence of celiac disease (CD) has increased in recent decades without a clear explanation. The hygiene hypothesis theorizes that decreased exposure to bacterial antigens may trigger autoimmunity. We aimed to determine whether Helicobacter pylori infection and CD were associated among patients undergoing upper gastrointestinal endoscopy. We performed a cross-sectional study of patients who underwent esophagogastroduodenoscopy with submission of gastric and duodenal biopsies to Miraca Life Sciences, Inc. (Irving, Texas), a US commercial pathology laboratory, during a 4.5-year period (January 2008June 2012). We compared the prevalence of H. pylori in CD patients with that in persons without CD. We performed multiple logistic regression analysis, adjusting odds ratios for patient age, gender, and racial, ethnic, and socioeconomic factors. Among 136,179 patients, a total of 2,689 (2.0) had CD. H. pylori prevalence was significantly lower in patients with CD (4.4) than in those without CD (8.8; P 0.0001). After adjustment for the above covariates, this inverse relationship remained strong (adjusted odds ratio (OR) 0.48, 95 confidence interval (CI): 0.40, 0.58). The relationships were similar in men (unadjusted OR 0.51, 95 CI: 0.38, 0.69) and women (unadjusted OR 0.46, 95 CI: 0.36, 0.58) and in all age groups. We conclude that H. pylori presence and CD are inversely associated, a relationship that persists after adjustment for socioeconomic factors. Future studies should address whether H. pylori modulates immune responses to ingested gluten.

- Background and aim: Isotretinoin, a vitamin A analogue, can promote a pro-inflammatory milieu in the small intestine in response to dietary antigens. We hypothesized that oral isotretinoin exposure would increase the risk of celiac disease (CD).Methods: We contacted all 28 pathology departments in Sweden, and through biopsy reports identified 26,739 individuals with CD. We then compared the prevalence of ever using oral isotretinoin to the prevalence in 134,277 matched controls through conditional logistic regression. Data on isotretinoin exposure were obtained from the national Swedish Prescribed Drug Registry. As the only indication for isotretinoin use in Sweden is acne, we also examined its relationship to CD. Data on acne were obtained from the Swedish Patient Registry.Results: Ninety-three individuals with CD (0.35 %) and 378 matched controls (0.28 %) had a prescription of isotretinoin. This corresponded to an odds ratio (OR) of 1.22 [95 % confidence interval (CI) 0.97-1.54]. Risk estimates were similar in men and women, and when we restricted our data to individuals diagnosed after the start of the Prescribed Drug Registry. Restricting our analyses to individuals diagnosed aged 12-45 years did not influence the risk estimates (OR 1.38, 95 % CI 0.97-1.97). Meanwhile, having a diagnosis of acne was positively associated with CD (OR 1.34, 95 % CI 1.20-1.51).Conclusions: This study found no association between isotretinoin use and CD, but a small excess risk of CD in patients with a diagnosis of acne.

Tidskriftsartikel (refereegranskat)abstract
- Background: Celiac disease (CD) is associated with an increased risk for lymphoproliferative malignancy (LPM). Whether this risk is affected by the results of follow-up intestinal biopsy, performed to document mucosal healing, is unknown. Objective: To examine the association between mucosal healing in CD and subsequent LPM. Design: Population-based cohort study. Setting: 28 pathology departments in Sweden. Patients: 7625 patients with CD who had follow-up biopsy after initial diagnosis. Measurements: The risk for LPM was compared with that of the general population by using expected rates. The rate of LPM in patients with persistent villous atrophy was compared with that of those with mucosal healing by using Cox regression. Results: Among 7625 patients with CD and follow-up biopsy, 3308 (43%) had persistent villous atrophy. The overall risk for LPM was higher than that in the general population (standardized incidence ratio [SIR], 2.81 [95% CI, 2.10 to 3.67]) and was greater among patients with persistent villous atrophy (SIR, 3.78 [CI, 2.71 to 5.12]) than among those with mucosal healing (SIR, 1.50 [CI, 0.77 to 2.62]). Persistent villous atrophy compared with mucosal healing was associated with an increased risk for LPM (hazard ratio [HR], 2.26 [CI, 1.18 to 4.34]). The risk for T-cell lymphoma was increased (HR, 3.51 [CI, 0.75 to 16.34]) but not for B-cell lymphoma (HR, 0.97 [CI, 0.21 to 4.49]). Limitation: No data on dietary adherence. Conclusion: Increased risk for LPM in CD is associated with the follow-up biopsy results, with a higher risk among patients with persistent villous atrophy. Follow-up biopsy may effectively stratify patients with CD by risk for subsequent LPM.

Mucosal healing and the risk of ischemic heart disease or atrial fibrillation in patients with celiac disease : a population-based study
- 2015

Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 10:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Patients with celiac disease (CD), characterized histologically by villous atrophy (VA) of the small intestine, have an increased risk of ischemic heart disease (IHD) and atrial fibrillation (AF), risks that persist for years after commencing the gluten-free diet. It is unknown whether persistent VA on follow-up biopsy, rather than mucosal healing, affects the risk of IHD or AF.Methods: We identified patients with histologic evidence of CD diagnosed at all 28 pathology departments in Sweden. Among patients who underwent a follow-up small intestinal biopsy, we compared patients with persistent VA to those who showed histologic improvement, with regard to the development of IHD (angina pectoris or myocardial infarction) or AF.Results: Among patients with CD and a follow-up biopsy (n = 7,440), the median age at follow-up biopsy was 25 years, with 1,063 (14%) patients who were >= 60 years at the time of follow-up biopsy. Some 196 patients developed IHD and 205 patients developed AF. After adjusting for age, gender, duration of CD, calendar period, and educational attainment, there was no significant effect of persistent VA on IHD (adjusted HR 0.97; 95%CI 0.73-1.30). Adjusting for diabetes had a negligible effect (adjusted HR 0.98; 95%CI 0.73-1.31). There was no significant association between persistent VA and the risk of AF (adjusted HR 0.98; 95%CI 0.74-1.30).Conclusions: In this population-based study of patients with CD, persistent VA on follow-up biopsy was not associated with an increased risk of IHD or AF. Failed mucosal healing does not influence the risk of these cardiac events.

- BACKGROUND & AIMS: Studies have associated undiagnosed celiac disease with adverse outcomes of pregnancy. We investigated the association between persistent villous atrophy and outcomes of pregnancy in women with celiac disease.METHODS: We collected data on 337 women with celiac disease who gave birth (to 460 infants) within 5 years of a follow-up biopsy, from 28 pathology departments in Sweden. We compared birth outcomes from women whose follow-up biopsy showed persistent villous atrophy (Marsh score, 3; n = 142; 31% of study population) with those of women with mucosal recovery (n = 318; 69%). We used multivariable logistic regression (adjusted for maternal age, parity, country of birth, smoking, infant sex, and calendar year of birth) to evaluate the association between persistent villous atrophy and pregnancy outcomes.RESULTS: Intrauterine growth restriction occurred during 3.5% of pregnancies in women with persistent villous atrophy vs 3.8% of those with mucosal healing (adjusted odds ratio [OR], 0.61; 95% confidence interval [CI], 0.19-1.99). There was no significant association between persistent villous atrophy and low birth weight (OR, 0.98; 95% CI, 0.41-2.39), preterm birth (OR, 1.66; 95% CI, 0.72-3.83), or cesarean section (OR, 0.86; 95% CI, 0.51-1.46).CONCLUSIONS: Although undiagnosed celiac disease has been associated with adverse outcomes of pregnancy, we found no evidence from a nationwide population-based study that persistent villous atrophy, based on analysis of follow-up biopsies, increases risk compared with mucosal healing.

- Context: Celiac disease (CD) is associated with an increased fracture risk, an increase that persists after diagnosis. A significant proportion of patients with CD have persistent villous atrophy (VA) on follow-up biopsy. Objective: The objective of the study was to determine whether persistent VA impacts long-term fracture risk. Design: This was a cohort study. Setting and Patients: We identified all patients in Sweden with histological evidence of CD who underwent a follow-up biopsy and compared patients with persistent VA with those with mucosal healing. Main Outcome Measures: The following were measured: 1) any fracture; 2) likely osteoporotic fracture (defined as fractures of the hip, distal forearm, thoracic and lumbar spine, or proximal humerus); and 3) hip fracture. Results: Of 7146 patients, VA was present on follow-up biopsy in 43%. There was no significant association between persistent VA and overall fractures [hazard ratio (HR) of persistent VA compared with those with healing 0.93, 95% confidence interval (CI) 0.82-1.06] or with likely osteoporotic fractures (HR 1.11, 95% CI 0.84-1.46). Persistent VA was associated with an increased risk of hip fracture (HR 1.67, 95% CI 1.05-2.66). Hip fracture risk increased, depending on the degree of VA (HR for partial VA compared with those with healing 1.70, 95% CI 0.82-3.49, HR for subtotal/total VA compared with those with healing 2.16, 95% CI 1.06-4.41). Conclusions: Persistent VA on follow-up biopsy is predictive of hip fracture risk. The association between persistent VA and hip fractures, but not fractures overall, implies that thinner sc tissue

- BACKGROUND & AIMS: Few studies have explored the link between childhood celiac disease and long-term psychiatric comorbidities. We performed a population-based cohort study of associations between childhood celiac disease and psychiatric disorders and investigated whether risk persists into adulthood.METHODS: We performed a nationwide study in Sweden using data from the ESPRESSO cohort. In this cohort, 19,186 children with a diagnosis of biopsy-verified celiac disease from 1973 through 2016 were identified from Sweden's 28 pathology departments. Each patient was matched with as many as 5 reference children (controls, n=94,249). Data on psychiatric disorders were obtained from the patient register. We used Cox proportional modeling to estimate hazard ratios (HRs).RESULTS: During a median follow-up time of 12.3 years, 3174 children (16.5%) with celiac disease received a new diagnosis of a psychiatric disorder, compared with 13,286 controls (14.1%). Corresponding incidence rates were 12.2 per 1000 person-years (95% Cl, 11.8-12.7) vs 10.3 per 1000 person-years (95% Cl, 10.2-10.5). Childhood celiac disease was associated with a 19% increase in risk of any psychiatric disorder (95% Cl, 1.14-1.23); the increase in risk was observed in all childhood age groups. The highest HRs were seen in the first year after celiac diagnosis (HR, 1.70; 95% Cl, 1.41-2.05). The risk increase persisted into adulthood (older than 18 years: HR, 1.11; 95% Cl, 1.04-1.17). We found increased risks of mood disorders (HR, 1.20; 95% CI, 1.12-1.28), anxiety disorders (HR, 1.12; 95% CI, 1.06-1.19), eating disorders (HR, 1.34; 95% CI, 1.18-1.51), attention deficit hyperactivity disorder (HR, 1.29; 95% CI, 1.20-1.39), and autism spectrum disorder (HR, 1.47; 95% CI, 1.32-1.64). We found no statistically significant risk increase for psychotic disorders, psychoactive substance misuse, behavioral disorders, personality disorders, suicide attempt, or suicide. Celiac disease was also linked to an increased use of psychiatric drugs (HR, 1.34; 95% CI, 1.24-1.43). A conditional logistic regression found that psychiatric disorders were also more common prior to diagnosis of celiac disease (odds ratio, 1.56; 95% Cl, 1.39-1.76).CONCLUSIONS: Childhood celiac disease is associated with increased risk of subsequent psychiatric disorders, which persists into adulthood. Mental health surveillance should be integral in the care of celiac disease.

- OBJECTIVES: Patients with celiac disease are at increased risk for infections such as tuberculosis, influenza, and pneumococcal pneumonia. However, little is known about the incidence of Clostridium difficile infection (CDI) in patients with celiac disease.METHODS: We identified patients with celiac disease based on intestinal biopsies submitted to all pathology departments in Sweden over a 39-year period (from July 1969 through February 2008). We compared risk of CDI (based on stratified Cox proportional hazards models) among patients with celiac disease vs. without celiac disease (controls) matched by age, sex, and calendar period.RESULTS: We identified 28,339 patients with celiac disease and 141,588 controls; neither group had a history of CDI. The incidence of CDI was 56/100,000 person-years among patients with celiac disease and 26/100,000 person-years among controls, yielding an overall hazard ratio (HR) of 2.01 (95% confidence interval (CI), 1.64-2.47; P<0.0001). The risk of CDI was highest in the first 12 months after diagnosis of celiac disease (HR, 5.20; 95% CI, 2.81-9.62; P<0.0001), but remained high, compared to that of controls, 1-5 years after diagnosis (HR, 1.85; 95% CI, 1.22-2.81; P=0.004). Among 493 patients with CDI, antibiotic data were available for 251; there were no significant differences in prior exposures to antibiotics between patients with celiac disease and controls.CONCLUSIONS: In a large population-based cohort study, patients with celiac disease had significantly higher incidence of CDI than controls. This finding is consistent with prior findings of higher rates of other infections in patients with celiac disease, and suggests the possibility of altered gut immunity and/or microbial composition in patients with celiac disease.

- Background: Celiac disease (CD) carries an increased risk of several malignancies, including cancers of the gastrointestinal tract and hematologic malignancies. The disease course of cutaneous malignant melanoma (CMM) is affected by the immune status of the host, and therefore may be associated with CD.Objective: We sought to test for an association between CD and CMM in a population-based setting.Methods: We queried all (n = 28) pathology departments in Sweden and identified patients with intestinal histology consistent with CD. Each patient was matched to up to 5 control subjects by age, gender, calendar period, and region. Using Cox proportional hazards, we tested for an association between CD and the subsequent diagnosis of CMM.Results: Among patients with CD (n = 29,028), 78 subsequently developed CMM (0.3%). Compared with control subjects there was no significant association between CD and CMM (hazard ratio 0.94, 95% confidence interval 0.73-1.20). This null association was similar for men (hazard ratio 0.99, 95% confidence interval 0.68-1.44) and women (hazard ratio 0.89, 95% confidence interval 0.64-1.24), and in all age strata.Limitations: Lack of data regarding undiagnosed CD is a limitation.Conclusion: In this population-based study we found no association between CD and the subsequent diagnosis of CMM. Prior studies showing a positive association between these 2 entities may have been a result of referral bias.

- Background: Patients with celiac disease (CD) frequently report cognitive symptoms when they are exposed to gluten, and cognitive deficits have been quantified in patients with newly diagnosed CD. Objective: To determine whether patients with CD have an increased risk of dementia. Methods: Using a population-based database of older adults (age >= 50 years) with histologically proven CD (duodenal/jejunal villous atrophy) from all 28 pathology departments in Sweden, we compared the incidence of a subsequent dementia diagnosis to those of age-and gender-matched controls. Results: Among patients with CD (n = 8,846) and controls (n = 43,474), the median age was 63 years and 56% were female. During a median follow-up time of 8.4 years, dementia was diagnosed in 4.3% of CD patients and 4.4% of controls (HR 1.07; 95% CI 0.95-1.20). Although there was an increased risk of dementia in the first year following a diagnosis of CD (HR 1.73; 95% CI 1.15-2.61), this risk was not present in the whole observation period. Among those subjects with a dementia subtype specified, the increased risk was restricted to vascular dementia (HR 1.28; 95% CI 1.00-1.64) and was not present for Alzheimer's dementia (HR 1.12; 95% CI 0.91-1.37). Conclusions: Patients with CD are not at increased risk for dementia overall, though subgroup analysis suggests that they may be at increased risk for vascular dementia.

- Background and Aims: Patients with celiac disease (CD) are reported to be at increased risk for headaches, though large studies are lacking. We aimed to examine the risk of headache-related healthcare encounters in patients with CD in a nationwide population-based setting.Methods: In this population-based retrospective cohort study, we searched all (n = 28) pathology departments in Sweden and identified patients with CD based on the presence of villous atrophy (VA). Each patient was matched to up to 5 controls, by age, gender, calendar period, and region. Using Cox proportional hazards, we tested for an association between CD and subsequent headache-related visit. We also tested this association for those with intestinal inflammation but normal villi, and subjects with positive CD serologies but normal histology.Results: Among 28,638 patients with CD and 143,126 controls, headache-related visit occurred in 1,337 (4.7%) and 4,102 (2.9%), respectively. The incidence of headache-related visit was 423 per 100,000 person-years in CD patients and 254 per 100,000 person-years in controls (HR 1.66; 95% CI 1.56-1.77; P < .0001). Individuals having inflammation without VA on small intestinal biopsy (n = 12,898; HR 2.08; 95% CI 1.90-2.27; P < .0001) and those with normal mucosa but positive CD serology (n = 3,617; HR 1.83; 95% CI 1.57-2.12; P < .0001) were also at increased risk for headache-related visit.Conclusions: In this population-based study we found a significantly increased risk of headache-related visits in patients with CD; this increase was also present in patients with intestinal inflammation and those with positive CD serology but with normal mucosal architecture on small bowel biopsy. Though limited by surveillance bias, this study indicates that headache-related visits are more common in these populations.

- Background: Patients with celiac disease (CeD) are at increased risk of certain viral infections and of pneumococcal pneumonia, raising concerns that they may be susceptible to severe coronavirus disease 2019 (Covid-19). We aimed to quantify the association between CeD and severe outcomes related to Covid-19.Methods: We performed a population-based cohort study, identifying individuals with CeD in Sweden, as defined by small intestinal villus atrophy diagnosed at all (n=28) Swedish pathology departments during the years spanning 1969-2017, and alive on February 1, 2020. We compared these patients to controls matched by sex, age, county, and calendar period. We performed Cox proportional hazards with follow-up through July 31, 2020, assessing risk of 1) hospital admission with a primary diagnosis of laboratory-confirmed Covid-19 (co-primary outcome); and 2) severe disease as defined by admission to intensive care unit and/or death attributed to Covid-19 (co-primary outcome).Results: Among patients with CeD (n=40,963) and controls (n=183,892), the risk of hospital admission for Covid-19 was 2.9 and 2.2 per 1000 person-years respectively. After adjusting for comorbidities, the risk of hospitalization for Covid-19 was not significantly increased in patients with CeD (HR 1.10; 95% CI 0.80-1.50), nor was the risk of severe Covid-19 increased (HR 0.97; 95% CI 0.59-1.59). Results were similarly null when we compared CeD patients to their non-CeD siblings with regard to these outcomes. Among all patients with CeD and controls hospitalized with a diagnosis of Covid-19 (n=58 and n=202, respectively), there was no significant difference in mortality (HR for CeD compared to controls 0.96; 95% CI 0.46-2.02).Conclusion: In this population-based study, CeD was not associated with an increased risk of hospitalization for Covid-19 or intensive care unit and/or death attributed to Covid-19.

- Background and objective Genetic factors alone cannot explain the risk of developing coeliac disease (CD). Children born in summer months are likely to be weaned and introduced to gluten during winter when viral infections are more frequent. Earlier studies on birth season and CD are limited in sample size and results are contradictory. Method Case-control study. We used biopsy reports from all 28 Swedish pathology departments to identify individuals with CD, defined as small intestinal villous atrophy (n=29 096). The government agency Statistics Sweden then identified 144 522 controls matched for gender, age, calendar year and county. Through conditional logistic regression we examined the association between summer birth (March-August) and later CD diagnosis (outcome measure). Results Some 54.10% of individuals with CD versus 52.75% of controls were born in the summer months. Summer birth was hence associated with a small increased risk of later CD (OR 1.06; 95% CI 1.03 to 1.08; p<0.0001). Stratifying CD patients according to age at diagnosis, we found the highest OR in those diagnosed before age 2 years (OR 1.17; 95% CI 1.10 to 1.26), while summer birth was not associated with a CD diagnosis in later childhood (age 2-18 years: OR 1.02; 95% CI 0.97 to 1.08), but had a marginal effect on the risk of CD in adulthood (age >= 18 years: OR 1.04; 95% CI 1.01 to 1.07). Conclusions In this study, summer birth was associated with an increased risk of later CD, but the excess risk was small, and general infectious disease exposure early in life is unlikely to be a major cause of CD.

- Background: The prevalence of celiac disease and the use of medications that inhibit acid secretion have both increased in recent decades. Aim: To explore the association between antisecretory medication exposure and subsequent development of celiac disease. Methods: In this population-based case control study, we identified patients with celiac disease diagnosed at all pathology departments in Sweden from July 2005 through February 2008. Patients were matched by age and gender with up to 5 controls. We identified prior prescriptions for proton pump inhibitors and histamine-2 receptor antagonists in all subjects. We used conditional logistic regression to measure the association between these prescriptions and the subsequent diagnosis of celiac disease. Results: Prior proton pump inhibitor prescription was strongly associated with celiac disease (OR 4.79; 95% CI 4.17-5.51). Patients prescribed both proton pump inhibitors and histamine-2 receptor antagonists had a higher risk of celiac disease (OR 5.96; 95% CI 3.58-9.91) than those prescribed proton pump inhibitors alone (OR 4.91; 95% CI 4.26-5.66) or histamine-2 receptor antagonists alone (OR 4.16; 95% CI 2.89-5.99). Conclusions: Exposure to antisecretory medications is associated with a subsequent diagnosis of celiac disease. The persistence of this association after excluding prescriptions in the year preceding the celiac disease diagnosis suggests a causal relationship.

- OBJECTIVE: Microscopic colitis is a common cause of chronic watery diarrhea among the elderly. Although the prevalence of celiac disease appears to be higher in patients with microscopic colitis, the relationship between dietary gluten intake and risk of microscopic colitis among individuals without celiac disease has not been explored.METHODS: We conducted a prospective study of 160,744 US women without celiac disease enrolled in the Nurses' Health Study (NHS) and the NHSII. Dietary gluten intake was estimated using validated food frequency questionnaires every 4 years. Microscopic colitis was confirmed through medical records review. We used Cox proportional hazard modeling to estimate the multivariable-adjusted hazard ratio (HR) and 95% confidence interval (CI).RESULTS: We documented 219 incident cases of microscopic colitis over more than 20 years of follow-up encompassing 3,716,718 person-years (crude incidence rate: 5.9/100,000 person-years) in NHS and NHSII. Dietary gluten intake was not associated with risk of microscopic colitis (Ptrend = 0.88). Compared to individuals in the lowest quintile of energy-adjusted gluten intake, the adjusted HR of microscopic colitis was 1.18 (95% CI: 0.77-1.78) for the middle quintile and 1.03 (95% CI: 0.67-1.58) for the highest quintile. Additional adjustment for primary dietary sources of gluten including refined and whole grains did not materially alter the effect estimates (All Ptrend ≥ 0.69). The null association did not differ according to lymphocytic or collagenous subtypes (Pheterogeneity = 0.72) and was not modified by age, smoking status, or body mass index (All Pinteraction ≥ 0.17).CONCLUSION: Dietary gluten intake during adulthood was not associated with risk of microscopic colitis among women without celiac disease.

- BACKGROUND & AIMS: Diet is thought to play a role in the development of inflammatory bowel disease (IBD), though the relationship between gluten intake and risk of IBD has not been explored. The aim of this study was to determine the relationship between gluten intake and risk of incident Crohn's disease (CD) and ulcerative colitis (UC).METHODS: We performed a prospective cohort study of 208,280 US participants from the Nurses' Health Study (NHS; 1986-2016), NHSII (1991-2017), and Health Professionals Follow-up Study (1986-2016) who did not have IBD at baseline or celiac disease, and who completed semi-quantitative food frequency questionnaires. We used Cox proportional hazards modeling to estimate the risk of IBD according to quintiles of cumulative average energy-adjusted dietary gluten intake over follow-up period.RESULTS: We documented 337 CD cases and 447 UC cases over 5,115,265 person-years of follow-up evaluation. Dietary gluten intake was not associated with risk of IBD. Compared with participants in the lowest quintile of gluten intake, the adjusted hazard ratios and 95% CIs for participants in the highest quintile of gluten intake were 1.16 (95% CI, 0.82-1.64; P-trend = .41) for CD and 1.04 (95% CI, 0.75-1.44; P-trend = .64) for UC. Adjusting for primary sources of gluten intake did not materially change our estimates.CONCLUSIONS: In three large adult US prospective cohorts, gluten intake was not associated with risk of CD or UC. Our findings are reassuring at a time when consumption of gluten has been increasingly perceived as a trigger for chronic gastrointestinal diseases.

- Background: Coeliac disease has been linked to anxiety and depression. However, their association with mucosal healing is unknown.Aim: To examine the relationship between anxiety, depression and mucosal healing in coeliac disease.Methods: Between 1969 and 2008, we collected data on all small intestinal biopsies with villous atrophy from Sweden's 28 pathology departments. We restricted our cohort to individuals with data on follow-up biopsy (either persistent villous atrophy [n = 3317] or mucosal healing [n = 4331]). Through Cox regression, we estimated hazard ratios (HRs) for anxiety or depression.Results: Conclusion APPENDIX During follow-up, 123 (2.8/1000 person-years) individuals with mucosal healing had developed anxiety, compared to 94 (2.1/1000 person-years) with persistent villous atrophy. Mucosal healing was hence associated with a higher risk of future anxiety (HR = 1.49; 95% CI = 1.12-1.96). Similarly, 167 (3.8/1000 person-years) individuals with mucosal healing developed depression, compared to 148 (3.3/1000 person-years) with persistent villous atrophy, corresponding to a HR of 1.25 (95% CI = 0.99-1.59). Mucosal healing was more common in individuals with prior diagnoses of anxiety or depression before follow-up biopsy. Anxiety diagnosed between diagnostic and follow-up biopsy for coeliac disease was associated with an almost nine-fold increased chance of mucosal healing (odds ratio = 8.94; 95%CI = 2.03-39.27).Conclusion: Anxiety and depression are more common in coeliac disease patients with mucosal healing, both before and after follow-up biopsy, an association potentially mediated through more vigilant compliance with a gluten-free diet. This finding raises concern that achieving the goal of mucosal healing may come at a cost of an increased risk of mood disorders.

- BACKGROUND & AIMS: Partner burden is common in celiac disease (CD), but it is unclear if parents of children with CD have increased burden, and if this may translate into depression and anxiety meriting healthcare.METHODS: Nationwide population-based study of 41,753 parents and spouses ("caregivers") to 29,096 celiac patients and 215,752 caregivers to 144,522 matched controls. Caregivers were identified from the Swedish Total Population Register, and linked to data on psychiatric disease in the National Patient Registry. Hazard ratios (HRs) for depression, anxiety, and (as a reference outcome measure) bipolar disorder were examined in a lifetime fashion but also in temporal relationship to date of CD diagnosis using Cox regression. A priori, we focused on parents of individuals diagnosed ≤19 years of age (children at the age of disease onset) and spouses of individuals diagnosed in adulthood, as such parents and spouses ("high-risk caregivers") were most likely to live together with the patient at time of disease onset.RESULTS: On Cox analysis, depression was 11% more common in high-risk caregivers (HR=1.11: 95%CI=1.03-1.19) than in control caregivers while anxiety was 7% more common (HR=1.07: 95%CI=0.98-1.16). Combining anxiety and depression into a composite outcome measure, there was an 8% statistically significant risk increase (95%CI=1.02-1.14). The highest excess risks for both depression and anxiety were seen just before and 4-8 years after the CD diagnosis. In contrast, bipolar disorder was not more common in caregivers to CD patients.CONCLUSION: Caregivers to patients with CD may be at increased risk of severe burden.

Tidskriftsartikel (refereegranskat)abstract
- Background: Individuals with Down syndrome (DS) have increased mortality and are also at increased risk of celiac disease (CD). It is unknown if CD influences mortality in DS. In this study we examined the risk of death in individuals with DS according to celiac status.Methods: In this nationwide population-based cohort study, we first identified individuals with CD (diagnosed 1969-2008) through small intestinal biopsy report data showing villous atrophy (Marsh stage III) from Sweden's 28 pathology departments. Celiac individuals were then matched with up to five reference individuals from the general population. In these cohorts we identified individuals with DS using International Classification of Disease codes (ICD) registered in the Swedish Patient Register (includes inpatients and hospital-based outpatients), the Medical Birth Register, and the Register of Congenital Malformations. Of 29,096 individuals with CD, 201 (0.7%) had DS compared to 124 of the 144,522 reference individuals (0.09%). Data on mortality were obtained from the Swedish Cause of Death Registry. Hazard ratios (HRs) for death were calculated using Cox regression.Results: During follow-up, there were seven deaths among individuals with DS and CD (7/201, 3.5%) as compared with 14 deaths among DS individuals without a record of CD (14/124, 11.3%). Adjusting for potential confounders, CD did not influence the risk of death in DS (HR = 1.36; 95%CI = 0.33-5.59). Cardiovascular death occurred in two individuals with CD and three individuals without CD, while death from malignancy occurred in one individual with CD and two individuals without CD.Conclusion: While both DS and CD have been linked to increased risk of death, this study found no excess mortality in DS patients with a concurrent diagnosis of CD, however confidence intervals were wide.

- Celiac disease (CD) is associated with both lymphoproliferative malignancy (LPM) and increased death from LPM. Research suggests that co-existing autoimmune disease may influence survival in LPM. Through Cox regression we examined overall and cause-specific mortality in 316 individuals with CD+LPM versus 689 individuals with LPM only. CD was defined as having villous atrophy according to biopsy reports at any of Sweden's 28 pathology departments, and LPM as having a relevant disease code in the Swedish Cancer Register. During follow-up, there were 551 deaths (CD: n = 200; non-CD: n = 351). Individuals with CD+LPM were at an increased risk of death compared with LPM-only individuals [adjusted hazard ratio (aHR) = 1.23; 95 % confidence interval (CI) = 1.02-1.48]. However, this excess risk was only seen in the first year after LPM diagnosis (aHR = 1.76), with HRs decreasing to 1.09 in years 2-5 after LPM diagnosis and to 0.90 thereafter. Individuals with CD and non-Hodgkin lymphoma (NHL) were at a higher risk of any death as compared with NHL-only individuals (aHR = 1.23; 95 % CI = 0.97-1.56). This excess risk was due to a higher proportion of T cell lymphoma in CD patients. Stratifying for T- and B cell status, the HR for death in individuals with CD+NHL was 0.77 (95 % CI = 0.46-1.31). In conclusion, we found no evidence that co-existing CD influences survival in individuals with LPM. The increased mortality in the first year after LPM diagnosis is related to the predominance of T-NHL in CD individuals. Individuals with CD+LPM should be informed that their prognosis is similar to that of individuals with LPM only. However, this study had low statistical power to rule our excess mortality in patients with CD and certain LPM subtypes.

- The vast majority of patients with celiac disease (CD) have disease-specific antibodies. If such antibodies-or other blood-borne factors that cause CD-are transmissible, it might be reflected by a higher risk of CD in individuals who receive blood from donors with incipient CD. In a retrospective nationwide cohort study of 1,058,289 individuals in Sweden who received a blood transfusion between 1968 and 2012, we examined the risk of transmission of CD (defined as having villous atrophy on small intestinal biopsy) using Cox regression. We also examined whether there were clusters of CD patients who received blood transfusions from the same donor independent of the known donor CD status. Overall, 9,455 patients who had undergone transfusions (0.9%) received a blood transfusion from a donor who had been diagnosed with CD. Of these, 14 developed CD, which corresponds to a hazard ratio of 1.0 (95% confidence interval: 0.9, 1.2) compared with recipients of transfusions from unaffected donors. There were no cases of CD among persons who received plasma or platelet units from donors with CD. We found no evidence of CD clustering among recipients of blood from individual donors (P for trend = 0.28). Our results suggest that CD is not transmitted through blood transfusions.

- Background & & Aims: Endoscopy is an integral part of the investigation and management of gastrointestinal disease. We aimed to examine outcomes of pregnancies for women who underwent endoscopy during their pregnancy.Methods: We performed a nationwide population-based cohort study, linking data from the Swedish Medical Birth Registry (for births from 1992 through 2011) with those from the Swedish Patient Registry. We identified 3052 pregnancies exposed to endoscopy (2025 upper endoscopies, 1109 lower endoscopies, 58 endoscopic retrograde cholangiopancreatographies). Using Poisson regression, we calculated adjusted relative risks (ARRs) for adverse outcomes of pregnancy according to endoscopy status using 1,589,173 unexposed pregnancies as reference. To consider the effects of disease activity, we examined pregnancy outcomes (preterm birth, stillbirth, small for gestational age [SGA], or congenital malformations) in women who underwent endoscopy just before or after pregnancy. Secondary factors included induction of labor, low birth weight (<2500g), cesarean section, Apgar score below 7 at 5 minutes, and neonatal death within 28 days. To consider intra-familial factors, we compared pregnancies within the same mother.Results: Exposure to any endoscopy during pregnancy was associated with an increased risk of preterm birth (ARR, 1.54; 95% CI, 1.36-1.75) or SGA (ARR, 1.30; 95% CI, 1.07-1.57) but not of congenital malformation (ARR, 1.00; 95% CI, 0.83-1.20) or stillbirth (ARR, 1.45; 95% CI, 0.87-2.40). None of the 15 stillbirths to women with endoscopy occurred less than 2 weeks after endoscopy. ARRs were independent of trimester. Compared to women with endoscopy less than 1 year before or after pregnancy, endoscopy during pregnancy was associated with preterm birth (ARR, 1.16) but not with SGA (ARR, 1.19), stillbirth (ARR, 1.11), or congenital malformation (ARR, 0.90). Restricting the study population to women having an endoscopy during pregnancy or before/after, and only analyzing data from women without a diagnosis of inflammatory bowel disease, celiac disease, or liver disease, endoscopy during pregnancy was not linked to preterm birth (ARR, 1.03; 95% CI, 0.84-1.27). Comparing births within the same mother, for which only 1 birth had been exposed to endoscopy, we found no association between endoscopy and gestational age or birth weight.Conclusions: In a nationwide population-based cohort study, we found endoscopy during pregnancy to be associated with increased risk of preterm birth or SGA, but not of congenital malformation or stillbirth. However, these risks are small and likely due to intra-familial factors or disease activity.
