Abstract
The breadth and validity of the associations of nongenetic risk factors with celiac disease (CeD) are elusive in the literature. We aimed to evaluate which of these associations have strong epidemiological credibility and assessed presence and extent of potential literature biases. We systematically searched PubMed until April 2024 for systematic reviews and meta-analyses of studies examining associations between putative risk factors and CeD. Each association was categorized in five evidence grades (convincing, highly suggestive, suggestive, weak, and not statistically significant) based on broadly used criteria for evaluating quality of evidence in observational studies. Five eligible publications were included, describing 15 meta-analytic associations on seven nongenetic risk factors, three of which were nominally significant ( P < 0.05). None of the associations received a strοng or highly suggestive evidence. One meta-analytic association received suggestive evidence, namely any infections during childhood and adulthood for a higher risk of CeD (OR, 1.37; 95% CI, 1.2-1.56; P =3.77 × 10 -6 ). Two meta-analyses reported weak evidence, pertaining to current smoking for a lower risk of CeD (OR, 0.52; 95% CI, 0.32-0.84; P =7.84 × 10 -3 ) and use of antibiotics for a higher risk (OR, 1.2; 95% CI, 1.04-1.38; P 14.8 × 10 -3 ). The rest of the meta-analyses did not report statistically significant results, and pertained to breastfeeding, time of gluten introduction, rotavirus vaccination, and cesarean section. No association of nongenetic risk factors for CeD received high levels of evidence. The evidence was suggestive for the association of any infections during childhood and adulthood with higher risk of CeD. More and prospective future research is warranted.

Abstract
OBJECTIVES During pregnancy, small quantities of maternal cells are naturally transmitted to the fetus. This transmission, termed maternal microchimerism (MMc), has been implicated in autoimmune diseases but its potential role is unclear. We aimed to investigate if MMc at birth predicted childhood celiac disease (CD) risk, a common immune-mediated enteropathy often presenting in childhood. METHODS We designed a case-control study, nested in the Norwegian Mother, Father and Child Cohort. Participants were HLA class II typed to determine noninherited, nonshared maternal alleles (NIMA). Droplet digital (dd) PCR assays specific for common HLA class II NIMAs (HLA-DQB103:01, 04:02 and 06:02/03) were used to estimate the quantity of maternal DNA, as a marker of maternal cells, in cord blood DNA from 124 children who later developed clinically diagnosed CD (median age at end of study 7.4 years, range 3.6-12.9) and 124 random controls. We tested whether presence of MMc was associated with CD using logistic regression, and compared ranks between cases and controls. RESULTS MMc, for example, maternal HLA antigens not inherited by the child, was found in 42% of cases and 43% of controls, and not associated with CD (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.58-1.60). The ranks of MMc quantities in cases and controls were also similar (Mann-Whitney U-test, P = 0.71). The subgroup with HLA-DQB1:03*01 as their NIMA had a potential association with MMc, where levels greater than median was associated with CD (OR 3.78, 95% CI 1.28-11.18). CONCLUSION MMc measured in cord blood was not associated with later risk of CD.

Abstract
Little is known about the effect of prematurity on later development of celiac disease (CD). We conducted a retrospective analysis of real-world data examining the association between very low birth weight (VLBW) prematurity and later development of CD autoimmunity (CDA) in 3580 infants born between years 2000 and 2012 and their matched controls. At a median of 12 years, VLBW prematurity was negatively associated with later development of CDA with a cumulative prevalence of 5.9 per 1000 versus 10.3 per 1000 (P = 0.02), though more former VLBW premature infants were ever tested for CDA (48.5% vs 37.4%, P < 0.001). The odds ratio for developing CDA among children born preterm at VLBW was 0.57 (95% confidence interval (CI) 0.35-0.92) as compared with matched controls. There was no difference in clinical characteristics of CDA between both groups. In conclusion, VLBW preterm infants present a decreased risk for the development of CDA during childhood and adolescence.

Abstract
BACKGROUND AND AIM There is evidence of a relationship between infection (and the associated antibiotic exposure) and the risk of celiac disease (CD). This study performed a meta-analysis to investigate this relationship. METHODS To identify relevant studies, we conducted systematic searches of the PubMed, Embase, and Cochrane databases for articles published up to April 2019. Random effects models were used to determine overall pooled estimates and 95% confidence intervals (CIs). RESULTS The meta-analysis included 19 observational studies (15 on infection and six on antibiotic exposure). Our results showed that any infection was associated with an increased risk of CD later in life (odds ratio, 1.37; 95% CI: 1.2-1.56; P < 0.001). The I2 was 94% (high heterogeneity among studies). Subgroup analyses suggested that the risk of CD is not affected by the type of infectious agent, timing of exposure, and site of infection. Exposure to antibiotics was also associated with new-onset CD (odds ratio, 1.2; 95% CI: 1.04-1.39; P < 0.001). CONCLUSION Exposure to early infection or antibiotic appears to increase the odds of developing CD, suggesting that intestinal immune or microbiota dysbiosis may play a role in the pathogenesis of CD. These findings may influence clinical management and primary prevention of CD. However, noncausal explanations for these positive associations cannot be excluded.

Abstract
Ecological observations suggest an inverse relationship between smoking in pregnancy and celiac disease (CD) in offspring. While individual-level analyses have been inconsistent, they have mostly lacked statistical power or refined assessments of exposure. To examine the association between pregnancy-related smoking and CD in the offspring, as well as its consistency across data sets, we analyzed: (1) The Norwegian Mother and Child Cohort (MoBa) of 94,019 children, followed from birth (2000–2009) through 2016, with 1035 developing CD; (2) a subsample from MoBa (381 with CD and 529 controls) with biomarkers; and (3) a register-based cohort of 536,861 Norwegian children, followed from birth (2004–2012) through 2014, with 1919 developing CD. Smoking behaviors were obtained from pregnancy questionnaires and antenatal visits, or, in the MoBa-subsample, defined by measurement of cord blood cotinine. CD and potential confounders were identified through nationwide registers and comprehensive parental questionnaires. Sustained smoking during pregnancy, both self-reported and cotinine-determined, was inversely associated with CD in MoBa (multivariable-adjusted [a] OR = 0.61 [95%CI, 0.46–0.82] and aOR = 0.55 [95%CI, 0.31–0.98], respectively); an inverse association was also found with the intensity of smoking. These findings differed from those of our register-based cohort, which revealed no association with sustained smoking during pregnancy (aOR = 0.97 [95%CI, 0.80–1.18]). In MoBa, neither maternal smoking before or after pregnancy, nor maternal or paternal smoking in only early pregnancy predicted CD. In a carefully followed pregnancy cohort, a more-detailed smoking assessment than oft-used register-based data, revealed that sustained smoking during pregnancy, rather than any smoking exposure, predicts decreased likelihood of childhood-diagnosed CD.

Abstract
Celiac disease is a common, chronic inflammatory disorder of the small intestine triggered by exposure to gluten in individuals with certain genetic types. This disorder affects people of any age or gender. Although often thought to be European in origin, it is now global in extent. Presentations are variable, from asymptomatic patients to severe malnutrition. Initial detection usually relies on celiac-specific serology, and confirmation often requires intestinal biopsy. There have been substantial increases in prevalence and incidence over the last 2 decades for reasons that are almost certainly environmental but for which there is no clarity as to cause.

Abstract
The ESPRESSO study constitutes a novel approach to examine the etiology and prognosis of gastrointestinal disease in which histopathology plays a prominent role. Between 2015 and 2017, all pathology departments (n=28) in Sweden were contacted and asked to procure histopathology record data from the gastrointestinal tract (pharynx to anus), liver, gallbladder, and pancreas. For each individual, local histopathology IT personnel retrieved data on personal identity number, date of histopathology, topography (where the biopsy is taken), morphology (biopsy appearance), and where available free text. In total, between 1965 and 2017, histopathology record data were available in 2.1 million unique individuals, but the number of data entries was 6.1 million because more than one biopsy was performed in many of the study participants. Index individuals with histopathology data were matched with up to five controls from the general population. We also identified all first-degree relatives (parents, children, full siblings), and the index individual's first spouse. The total study population consisted of 13.0 million individuals. Data from all the study participants have been linked to Swedish National Healthcare Registers allowing research not only on such aspects as fetal and perinatal conditions and the risk of future gastrointestinal disease but also on the risk of comorbidity and complications (including cancer and death). Furthermore, the ESPRESSO database allows researchers and practitioners to identify diagnoses and disease phenotypes not currently indexed in national registers (including disease precursors). The ESPRESSO database increases the sensitivity and specificity of already-recorded diseases in the national health registers. This paper is an overview of the ESPRESSO database.

Abstract
Purpose The purpose of this study was to investigate the association between mode of delivery and the risk of celiac disease in two large population-based birth cohorts with different prevalence of diagnosed celiac disease. Patients and methods This is an observational register-based cohort study using two independent population cohorts. We used data from administrative registers and health administrative registers from Denmark and Norway and linked the data at the individual level. We included all children who were born in Denmark from January 1, 1995 to December 31, 2010 and all children who were born in Norway from January 1, 2004 to December 31, 2012. Results We included 1,051,028 children from Denmark. Cesarean sections were registered for 196,512 children (18.9%). Diagnosed celiac disease was registered for 1,395 children (0.13%). We included 537,457 children from Norway. Cesarean sections were registered for 90,128 children (16.8%). Diagnosed celiac disease was registered for 1,919 children (0.35%). We found no association between the mode of delivery and the risk of diagnosed celiac disease. The adjusted odds ratio for celiac disease for children delivered by any type of cesarean section compared to vaginal delivery was 1.11 (95% CI: 0.96–1.29) in the Danish cohort and 0.96 (95% CI: 0.84–1.09) in the Norwegian cohort. The adjusted odds ratio for celiac disease for children delivered by elective cesarean section compared to vaginal delivery was 1.20 (95% CI: 1.00–1.43) in the Danish cohort and 0.96 (95% CI: 0.79–1.17) in the Norwegian cohort. Conclusion In this large registry-based study, mode of delivery was not associated with an increased risk of diagnosed celiac disease.

Abstract
Celiac disease (CD) is a chronic immune-mediated disorder triggered by the ingestion of gluten in genetically predisposed individuals. Before activating the immune system, gluten peptides are transferred by the epithelial barrier to the mucosal lamina propria, where they are deamidated by intestinal tissue transglutaminase 2. As a result, they strongly bind to human leucocyte antigens (HLAs), especially HLA-DQ2 and HLA-DQ8, expressed on antigen-presenting cells. This induces an inflammatory response, which results in small bowel enteropathy. Although gluten is the main external trigger activating both innate and adaptive (specific) immunity, its presence in the intestinal lumen does not fully explain CD pathogenesis. It has been hypothesized that an early disruption of the gut barrier in genetically susceptible individuals, which would result in an increased intestinal permeability, could precede the onset of gluten-induced immune events. The intestinal barrier is a complex functional structure, whose functioning is dependent on intestinal microbiota homeostasis, epithelial layer integrity, and the gut-associated lymphoid tissue with its intraepithelial lymphocytes (IELs). The aim of this paper was to review the current literature and summarize the role of the gut microbiota, epithelial cells and their intercellular junctions, and IELs in CD development.

Abstract
OBJECTIVES We aimed to study growth during the first 2 years of life in children later diagnosed with coeliac disease compared with children without, in a time with changing epidemiology and improved diagnostics. DESIGN A prospective population-based pregnancy cohort study. SETTING The nationwide Norwegian Mother and Child Cohort Study. PATIENTS 58 675 children born between 2000 and 2009 with prospectively collected growth data. Coeliac disease was identified through combined data from questionnaires and the Norwegian Patient Register. MAIN OUTCOME MEASURES The differences in height and weight at age 0, 3, 6, 8, 12, 15-18 and 24 months using internally standardised age and gender-specific z-scores. Linear regression and mixed models were used. RESULTS During a median follow-up of 8.6 years (range 4.6-14.2), 440 children (0.8%) were diagnosed with coeliac disease at a mean age of 4.4 years (range 1.5-8.5). Children with coeliac disease had significantly lower z-scores for height from 12 months (-0.09 standard deviation scores (SDS), 95% CI -0.18 to -0.01) and weight from 15 to 18 months of life (-0.09 SDS, 95% CI -0.18 to -0.01) compared with cohort controls. The longitudinal analysis from 0 to 24 months yielded a significant reduction in height z-score per year (-0.07 SDS, 95% CI -0.13 to -0.01) but not for weight among children with coeliac disease. Excluding children diagnosed before age 2 years gave similar results. CONCLUSIONS This study indicates that growth retardation in children later diagnosed with coeliac disease commonly starts at 12 months of age, and precedes clinical symptoms that usually bring the suspicion of diagnosis.

Abstract
Background Low concentration of 25-hydroxyvitamin D during pregnancy may be associated with offspring autoimmune disorders. Little is known about environmental triggers except gluten for celiac disease, a common immune-mediated disorder where seasonality of birth has been reported as a risk factor. We therefore aimed to test whether low maternal and neonatal 25-hydroxyvitamin D predicted higher risk of childhood celiac disease. Methods and Findings In this Norwegian nationwide pregnancy cohort (n = 113,053) and nested case-control study, we analyzed 25-hydroxyvitamin D in maternal blood from mid-pregnancy, postpartum and cord plasma of 416 children who developed celiac disease and 570 randomly selected controls. Mothers and children were genotyped for established celiac disease and vitamin D metabolism variants. We used mixed linear regression models and logistic regression to study associations. There was no significant difference in average 25-hydroxyvitamin D between cases and controls (63.1 and 62.1 nmol/l, respectively, p = 0.28), and no significant linear trend (adjusted odds ratio per 10 nM increase 1.05, 95% CI: 0.93–1.17). Results were similar when analyzing the mid-pregnancy, postpartum or cord plasma separately. Genetic variants for vitamin D deficiency were not associated with celiac disease (odds ratio per risk allele of the child, 1.00; 95% CI, 0.90 to 1.10, odds ratio per risk allele of the mother 0.94; 95% CI 0.85 to 1.04). Vitamin D intake in pregnancy or by the child in early life did not predict later celiac disease. Adjustment for established genetic risk markers for celiac disease gave similar results. Conclusions We found no support for the hypothesis that maternal or neonatal vitamin D status is related to the risk of childhood celiac disease.

Abstract
OBJECTIVES Infections in pregnancy are common, may affect fetal development, and have been linked to offspring autoimmunity. We aimed to determine whether maternal infections, the use of antibiotics, and use of paracetamol in pregnancy are associated with the risk of offspring celiac disease (CD). METHODS The nationwide Norwegian Mother and Child Cohort Study includes 84,274 children born in the period from 2000 to 2009 with prospectively collected questionnaire data on maternal infections and medication use in pregnancy. CD was identified through questionnaires and the Norwegian Patient Register. Logistic regression yielded odds ratios adjusted for age and sex (aORs). RESULTS During a median follow-up of 8.5 years, 617 children (0.7%) were diagnosed with CD. The aOR for offspring CD per increase in number of maternal infections was 1.07 (95% confidence interval [CI] = 1.01-1.13), but not significantly increased for categories 1 infection (1.01 [95% CI = 0.82-1.25]) and ≥2 infections (1.22 [95% CI = 1.00-1.49]) versus no infection. We found the same pattern for respiratory tract infections, but not for gastrointestinal infections. The aORs were broadly consistent across pregnancy periods of exposure. The use of antibiotics and paracetamol was, compared with no use, not associated with offspring CD (aOR = 1.16 [95% CI = 0.94-1.43] and aOR = 1.13 [95% CI = 0.96-1.33], respectively; P values for trend >0.2). CONCLUSIONS In this large pregnancy cohort we found no clear association between maternal infections in pregnancy and offspring CD, but considering the marginal significance in some of our results maternal infections cannot be ruled out as a risk factor. Reassuringly for both parents-to-be and clinicians, the use of antibiotics and paracetamol in pregnancy was not a significant risk factor.

Abstract
Non-IgE-mediated gastrointestinal food allergic disorders (non-IgE-GI-FA) including food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE), and food protein-induced allergic proctocolitis (FPIAP) are relatively uncommon in infants and young children, but are likely under-diagnosed. Non-IgE-GI-FA have a favorable prognosis, with majority resolving by age 3-5 years. Diagnosis relies on the recognition of symptoms pattern in FPIAP and FPIES and biopsy in FPE. Further studies are needed for a better understanding of the pathomechanism, which will lead eventually to the development of diagnostic tests and treatments. Limited evidence supports the role of food allergens in subsets of constipation, gastroesophageal reflux disease, irritable bowel syndrome, and colic. The immunologic pathomechanism is not fully understood and empiric prolonged avoidance of food allergens should be limited to minimize nutrient deficiency and feeding disorders/food aversions in infants.
