- INTRODUCTION: Patients with celiac disease (CD) have an increased risk of encapsulated bacterial infections. Less is known about other serious infections in CD, especially in patients diagnosed in the 21st century. METHODS: We contacted all 28 pathology departments in Sweden through the Epidemiology Strengthened by histoPathology Reports in Sweden (ESPRESSO) cohort study and identified 20,088 individuals with CD (defined as villous atrophy) diagnosed in 2002-2017. Patients were matched for sex, age, and calendar year to 80,152 general population comparators and followed up until December 31, 2019. Serious infections were defined as having a hospital-based (inpatient and outpatient) diagnosis in the National Patient Register. Cox regression yielded adjusted hazard ratios (aHR) controlling for education, country of birth, and comorbidities. RESULTS: During 173,695 person-years of follow-up, 6,167 individuals with CD (35.5/1,000 person-years) had a serious infection. This was compared with 19,131 infections during 743,260 person-years (25.7/1,000 person-years) in matched comparators, corresponding to an aHR of 1.29 (95% confidence interval [CI] = 1.25-1.33). aHR were similar when restricted to infection requiring hospital admission (1.23; 95% CI = 1.17-1.29). The excess risk of serious infections also persisted beyond the first year after CD diagnosis (aHR = 1.24; 95% CI = 1.20-1.29). Patients with CD were at risk of sepsis (aHR = 1.26; 95% CI = 1.09-1.45) and gastrointestinal infections (1.60; 95% CI = 1.47-1.74). Mucosal healing during CD follow-up did not influence the risk of subsequent serious infections. DISCUSSION: This nationwide study of patients with celiac disease diagnosed in the 21st century revealed a significantly increased risk of serious infections. While absolute risks were modest, vaccinations should be considered during CD follow-up care.

- 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.

- 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.

- 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.

- 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 & & 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.

- INTRODUCTION: Celiac disease (CD) affects 1% of the population. Its effect on healthcare cost, however, is barely understood. We estimated healthcare use and cost in CD, including their temporal relationship to diagnosis.METHODS: Through biopsy reports from Sweden's 28 pathology departments, we identified 40,951 prevalent patients with CD (villous atrophy) as of January 1, 2015, and 15,086 incident patients with CD diagnosed in 2008-2015, including 2,663 who underwent a follow-up biopsy to document mucosal healing. Each patient was compared with age- and sex-matched general population comparators (n = 187,542). Using nationwide health registers, we retrieved data on all inpatient and nonprimary outpatient care, prescribed diets, and drugs.RESULTS: Compared with comparators, healthcare costs in 2015 were, on average, $1,075 (95% confidence interval, $864-1,278) higher in prevalent patients with CD aged <18 years, $715 ($632-803) in ages 18-64 years, and $1,010 ($799-1,230) in ages ≥65 years. Half of all costs were attributed to 5% of the prevalent patients. Annual healthcare costs were $391 higher 5 years before diagnosis and increased until 1 year after diagnosis; costs then declined but remained 75% higher than those of comparators 5 years postdiagnosis (annual difference = $1,044). Although hospitalizations, nonprimary outpatient visits, and medication use were all more common with CD, excess costs were largely unrelated to the prescription of gluten-free staples and follow-up visits for CD. Mucosal healing in CD did not reduce the healthcare costs.DISCUSSION: The use and costs of health care are increased in CD, not only before, but for years after diagnosis. Mucosal healing does not seem to lower the healthcare costs.

- We aimed to determine the risk of incident cancer in autoimmune hepatitis (AIH) compared with the general population and siblings. AIH was defined by the presence of a medical diagnosis of AIH and results of examination of a liver biopsy specimen in a nationwide Swedish population-based cohort study. We identified 5,268 adults with AIH diagnosed during 1969-2016 and 22,996 matched, general population, reference individuals and 4,170 sibling comparators. Using Cox regression, hazard ratios were determined for any incident cancer, and subtypes were determined from the Swedish Cancer Register. During follow-up, a cancer diagnosis was made in 1,119 individuals with AIH (17.2 per 1,000 person-years) and 4,450 reference individuals (12.0 per 1,000 person-years). This corresponded to a hazard ratio of 1.53 (95% confidence interval: 1.42, 1.66). Cancer risk was highest in those with cirrhosis. There was a 29.18-fold increased risk of hepatocellular carcinoma (HCC) (95% confidence interval: 17.52, 48.61). The annual incidence risk of HCC in individuals with AIH who had cirrhosis was 1.1% per year. AIH was also linked to nonmelanoma skin cancer (hazard ratio (HR) = 2.69) and lymphoma (HR = 1.89). Sibling analyses yielded similar risk estimates for any cancer (HR = 1.84) and HCC (HR = 23.10). AIH is associated with an increased risk of any cancer, in particular, HCC and extrahepatic malignancies. The highest risk for cancer, especially HCC, is in patients with cirrhosis.

- 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.
