Psychological stress and coeliac disease in childhood: a cohort study.
Ontology highlight
ABSTRACT: Background
Psychological stress has previously been associated with several immunological diseases, e.g. inflammatory bowel disease. Through questionnaire data from the ABIS study (All Babies In southeast Sweden) we examined the association between psychological stress in the family and biopsy-proven coeliac disease (CD) in the child.Methods
We used serious life event, parenting stress, and parental worries as measures of psychological stress. Data were collected when the child was 1 and 2.5 years old in some 11,000 and 8,800 children, respectively. CD was confirmed through small intestinal biopsy (with villous atrophy), and the diagnosis was validated through patient chart data.Results
Serious life event in the family in the child's first 1 or 2.5 years after childbirth was not associated with future CD in the child (Odds Ratio (OR) = 0.45; 95% Confidence Interval (CI) = 0.01-2.65; P = 0.72; and OR = 1.21; 95% CI = 0.43-3.05; P = 0.64, respectively). Neither did we see any association between CD and parenting stress at age 1 year and at 2.5 years (OR = 0.40; 95% CI = 0.01-2.38; P = 0.73 and OR = 0.74; 95% CI = 0.01-4.56; P = 1.00, respectively). Among children exposed to parental worries at 2.5 years, no child had a diagnosis of CD before end of follow-up, compared to 25/8082 (0.3%) among non-exposed children (OR = 0.00; 95% CI = 0.00-2.34; P = 0.64). There was no association between the combined measures of stress and CD.Conclusion
This study found no association between psychological stress and later development of CD in Swedish children. However, we cannot rule out that the lack of such an association is due to limited statistical power.

Project description:ObjectivesThe aim of this study was to evaluate if the use of antitransglutaminase (tTG) and antiendomysium (EM) antibodies has modified the profile of coeliac disease (CD) in children.DesignRetrospective cohort study.SettingMonocentric study, in one major tertiary centre in Paris. Two cohorts of patients were compared; the first included patients before the use of antibodies, and the second included patients after the use of antibodies.ParticipantsAll patients from the same physician diagnosed with a CD between 1976 and 1992 (historical cohort), and between 1994 and 2007, were included in the study. 56 patients were included in the historical cohort, 59 in the recent cohort.Primary and secondary outcome measuresClinical, biological and histological profiles at diagnosis have been studied.ResultsThe recent cohort diagnosis of CD was based in 27% on a systematic screening (type I diabetes, n=10; CD in siblings, n=6). On comparison of CD patients in the historical to the recent cohort, the following significant differences were observed: Median age at diagnosis increased from 1 year to 2.7 years (p<0.0001). Patients in the historical cohort had more gastrointestinal symptoms (93% vs 63%, p=0.0001) and failure to thrive (98% vs 80%, p=0.0025). Nutritional deficiencies and morphological lesions were more severe in the historical cohort (90% subtotal or total villous atrophy vs 51%, p<0.0001). Differences observed between the two cohorts were mainly due to the presence of screened patients.ConclusionsA new type of patients, with a paucisymptomatic or asymptomatic CD, has been identified using serological tests. Silent disease has been diagnosed by screening in a target population. In the other patients of the recent cohort, symptoms were similar but less severe than those observed before. Long-term risks of untreated silent CD are not well determined as yet, and have to be evaluated in prospective studies.

Project description:Coeliac disease (CeD) has been associated with psychological disorders and reduced quality of life. Our prospective study evaluated the changes in the quality of life, anxiety and depression in CeD patients up to two years after diagnosis. We recruited adult patients residing in the Veneto region with a new diagnosis of CeD. Several validated questionnaires were administered to measure quality of life, psychological symptoms and adherence to a gluten-free diet (GFD) at the time of diagnosis and after 1 and 2 years. Ninety-three patients reached the 1-year follow-up (81.7% were females with a median age at diagnosis of 35 years), and 55 patients reached the 2-year follow-up. We observed a significant improvement in quality of life, anxiety and depression scores at 1 year after diagnosis, particularly in patients who complied with a GFD. The improvements among classical CeD patients were similar to those observed in nonclassical patients except for anxiety, which improved only in patients with a classical presentation at diagnosis. Age, sex and other disease factors did not affect the change in quality of life (QoL) or other mood disorders. Most of the improvements measured 1 year after diagnosis and 2 years after diagnosis were not significant. In conclusion, QoL and mood disorders must be considered, and psychological counselling should be used when needed.

Project description:BACKGROUND: The infant microbiota may play a pathogenic role in coeliac disease (CD). Antibiotic treatment in pregnancy is common and could significantly impact the infant microbiota. In this study, we aimed to investigate the association between antibiotic exposure during pregnancy and CD in offspring. METHODS: Prospective questionnaire data on antibiotic exposure in pregnancy were available in 8729 children participating in the All Babies in Southeast Sweden (ABIS) cohort study, and of these 46 developed CD until December 2006. Cox regression estimated hazard ratios (HRs) for CD in the offspring among mothers exposed to antibiotics during pregnancy, with adjustment for parent-reported diary data on breastfeeding, age at gluten introduction and number of infections in the child's first year of life. RESULTS: Of the 1836 children exposed to antibiotics during pregnancy, 12 (0.7%) children developed CD as compared with 34/6893 (0.5%) unexposed children (HR = 1.33; 95% CI = 0.69-2.56). Risk estimates remained unchanged after adjustment for breastfeeding, age at gluten introduction and infection load in the child's first year of life (HR = 1.28; 95% CI = 0.66-2.48). CONCLUSIONS: We found no statistically significant association between antibiotic exposure during pregnancy and CD in offspring. This lack of association may either be true or the result of limited statistical power.

Project description:ObjectiveTo determine whether infection with human enterovirus or adenovirus, both common intestinal viruses, predicts development of coeliac disease.DesignCase-control study nested within Norwegian birth cohort recruited between 2001 and 2007 and followed to September 2016.SettingNorwegian population.ParticipantsChildren carrying the HLA genotype DR4-DQ8/DR3-DQ2 conferring increased risk of coeliac disease.ExposuresEnterovirus and adenovirus detected using real time polymerase chain reaction in monthly stool samples from age 3 to 36 months.Main outcome measureCoeliac disease diagnosed according to standard criteria. Coeliac disease antibodies were tested in blood samples taken at age 3, 6, 9, and 12 months and then annually. Adjusted odds ratios from mixed effects logistic regression model were used to assess the relation between viral infections before development of coeliac disease antibodies and coeliac disease.ResultsAmong 220 children, and after a mean of 9.9 (SD 1.6) years, 25 children were diagnosed as having coeliac disease after screening and were matched to two controls each. Enterovirus was found in 370 (17%) of 2135 samples and was significantly more frequent in samples collected before development of coeliac disease antibodies in cases than in controls (adjusted odds ratio 1.49, 95% confidence interval 1.07 to 2.06; P=0.02). The association was restricted to infections after introduction of gluten. High quantity samples (>100 000 copies/μL) (adjusted odds ratio 2.11, 1.24 to 3.60; P=0.01) and long lasting infections (>2 months) (2.16, 1.16 to 4.04; P=0.02) gave higher risk estimates. Both the commonly detected enterovirus species Enterovirus A and Enterovirus B were significantly associated with coeliac disease. The association was not found for infections during or after development of coeliac disease antibodies. Adenovirus was not associated with coeliac disease.ConclusionsIn this longitudinal study, a higher frequency of enterovirus, but not adenovirus, during early childhood was associated with later coeliac disease. The finding adds new information on the role of viral infections in the aetiology of coeliac disease.

Project description:BACKGROUND:Serological studies indicate that evidence of coeliac disease (CD) exists in about 1% of all children, but we lack estimates of current diagnostic patterns among children and how they vary by socioeconomic group. METHODS:We identified all children aged 0-18?years between 1993 and 2012 who were registered with general practices across the UK that contribute to a large population-based general practice database. The incidence of CD was evaluated in each quintile of the Townsend index of deprivation and stratified by age, sex, country and calendar year. RESULTS:Among 2,063,421 children, we identified 1247 CD diagnoses, corresponding to an overall CD incidence of 11.9 per 100,000 person-years, which was similar across the UK countries and higher in girls than in boys. We found a gradient of CD diagnosis across socioeconomic groups, with the rate of diagnosis being 80% higher in children from the least-deprived areas than in those from the most-deprived areas (incident rate ratio 1.80, 95% CI 1.45 to 2.22). This pattern held for both boys and girls and across all ages. Across all four countries of the UK, we found similar associations between CD and socioeconomic status. While CD incidence up to age 2 remained stable over the study period, diagnoses at older ages have almost tripled over the past 20?years. CONCLUSIONS:Children living in less socioeconomically deprived areas in the UK are more likely to be diagnosed with CD. Increased implementation of diagnostic guidelines could result in better case identification in more-deprived areas.

Project description:Aims/hypothesisWhile the association between coeliac disease and type 1 diabetes is well documented, the association of coeliac disease with type 2 diabetes risk remains undetermined. We conducted a nationwide cohort and Mendelian randomisation analysis to investigate this link.MethodsThis nationwide matched cohort used data from the Swedish ESPRESSO cohort including 46,150 individuals with coeliac disease and 219,763 matched individuals in the comparator group selected from the general population, followed up from 1969 to 2021. Data from 9053 individuals with coeliac disease who underwent a second biopsy were used to examine the association between persistent villous atrophy and type 2 diabetes. Multivariable Cox regression was employed to estimate the associations. In Mendelian randomisation analysis, 37 independent genetic variants associated with clinically diagnosed coeliac disease at p<5×10-8 were used to proxy genetic liability to coeliac disease. Summary-level data for type 2 diabetes were obtained from the DIAGRAM consortium (80,154 cases) and the FinnGen study (42,593 cases).ResultsOver a median 15.7 years' follow-up, there were 6132 (13.3%) and 30,138 (13.7%) incident cases of type 2 diabetes in people with coeliac disease and comparator individuals, respectively. Those with coeliac disease were not at increased risk of incident type 2 diabetes with an HR of 1.00 (95% CI 0.97, 1.03) compared with comparator individuals. Persistent villous atrophy was not associated with an increased risk of type 2 diabetes compared with mucosal healing among participants with coeliac disease (HR 1.02, 95% CI 0.90, 1.16). Genetic liability to coeliac disease was not associated with type 2 diabetes in DIAGRAM (OR 1.01, 95% CI 0.99, 1.03) or in FinnGen (OR 1.01, 95% CI 0.99-1.04).Conclusions/interpretationCoeliac disease was not associated with type 2 diabetes risk.

Project description:ObjectivesCoeliac disease has emerged as an increasingly recognised public health problem over the last half-century, and is now coming to be seen as a global phenomenon, despite a profound lack of globally representative epidemiological data. Since children with coeliac disease commonly present with chronic diarrhoea and malnutrition, diagnosis is often overlooked, particularly in poorer settings where children often fail to thrive and water-borne infectious diarrhoeas are common. This is the first attempt to make global estimates of the burden of coeliac disease in childhood.MethodsWe built a relatively crude model of childhood coeliac disease, incorporating estimates of population prevalence, probability of non-diagnosis, and likelihood of mortality among the undiagnosed across all countries from 1970 to 2010, based around the few available data. All our assumptions are stated in the paper and the model is available as a supplementary file.FindingsOur model suggests that in 2010 there were around 2.2 million children under 5 years of age living with coeliac disease. Among these children there could be 42,000 deaths related to coeliac disease annually. In 2008, deaths related to coeliac disease probably accounted for approximately 4% of all childhood diarrhoeal mortality.ConclusionsAlthough coeliac disease may only account for a small proportion of diarrhoeal mortality, these deaths are not preventable by applying normal diarrhoea treatment guidelines, which may even involve gluten-based food supplements. As other causes of diarrhoeal mortality decline, coeliac disease will become a proportionately increasing problem unless consideration is given to trying gluten-free diets for children with chronic diarrhoea and malnutrition.

Project description:ObjectivesOur aim was to investigate the association between early environmental factors and the development of coeliac disease (CeD) in adolescents, recruited from a cohort nested in the Danish National Birth Cohort (DNBC).DesignThe study was designed as a prospective cohort study, nested in DNBC PARTICIPANTS: The Glutenfunen cohort comprises 1266 participants, nested in DNBC. All participants were screened for CeD, and in total, 28 cases of biopsy proven CeD were identified. Data about breastfeeding, timing of introduction to solid food in infancy, use of antibiotics, infections and symptoms were parentally reported prospectively at 6 months and 18 months, respectively. We estimated ORs and 95% CIs of CeD in adolescents using logistic regression analysis.ResultsViral croup reported at 18 months of age was associated with CeD in adolescents with an OR of 3.2 (95% CI: 1.2 to 8.7). Furthermore, otitis media also reported at 18 months of age was linked with CeD with an OR of 3.2 (95% CI: 1.5 to 7.3). We were not able to find any statistical associations between CeD and breastfeeding, frequency of infections, parentally reported use of antibiotic and timing of solid foods.ConclusionIn this study, we present an overview of the relationship between early environmental factors and occurrence of CeD in adolescents. Our findings, despite limitations due to a limited number of cases of CeD, suggest a role of viral infections in the pathogenesis of CeD.

Project description:This guideline presents recommendations for the management of coeliac disease (CD) and other gluten-related disorders both in adults and children. There has been a substantial increase in the prevalence of CD over the last 50 years and many patients remain undiagnosed. Diagnostic testing, including serology and biopsy, should be performed on a gluten-containing diet. The diagnosis of CD is based on a combination of clinical, serological and histopathological data. In a group of children the diagnosis may be made without biopsy if strict criteria are available. The treatment for CD is primarily a gluten-free diet (GFD), which requires significant patient education, motivation and follow-up. Slow-responsiveness occurs frequently, particularly in those diagnosed in adulthood. Persistent or recurring symptoms necessitate a review of the original diagnosis, exclude alternative diagnoses, confirm dietary adherence (dietary review and serology) and follow-up biopsy. In addition, evaluation to exclude complications of CD, such as refractory CD or lymphoma, should be performed. The guideline also deals with other gluten-related disorders, such as dermatitis herpetiformis, which is a cutaneous manifestation of CD characterized by granular IgA deposits in the dermal papillae. The skin lesions clear with gluten withdrawal. Also, less well-defined conditions such as non-coeliac gluten sensitivity (NCGS) and gluten-sensitive neurological manifestations, such as ataxia, have been addressed. Newer therapeutic modalities for CD are being studied in clinical trials but are not yet approved for use in practice.

Project description:IntroductionDermatitis herpetiformis (DH) is a cutaneous manifestation of coeliac disease. Increased cardiovascular morbidity has been reported in coeliac disease, but in DH only little is known about this. In this cohort study with a long-term follow-up, the risk for vascular diseases in patients with dermatitis herpetiformis (DH) and coeliac disease was assessed.MethodsThe study consisted of 368 DH and 1072 coeliac disease patients with biopsy-proven diagnosis performed between 1966 and 2000. For each DH and coeliac disease patient three matched reference individuals were obtained from the population register. Data regarding all outpatient and inpatient treatment periods between 1970 and 2015 were reviewed for diagnostic codes of vascular diseases from the Care Register for Health Care. Cox proportional hazard model was used to assess the risks for the diseases studied and the HRs were adjusted for diabetes mellitus (aHR).ResultsThe median follow-up time of DH and coeliac disease patients was 46 years. The risk for cardiovascular diseases did not differ between DH patients and their references (aHR 1.16, 95% CI 0.91-1.47), but among coeliac disease patients, the risk was increased (aHR 1.36, 95% CI 1.16-1.59). The risk for cerebrovascular diseases was found to be decreased in DH patients when compared with references (aHR 0.68, 95% CI 0.47-0.99) and increased in coeliac disease patients (aHR 1.33, 95% CI 1.07-1.66). The risk for venous thrombosis was increased in coeliac disease patients (aHR 1.62, 95% CI 1.22-2.16) but not in DH.ConclusionsThe risk for vascular complications appears to differ between DH and coeliac disease. In DH the risk for cerebrovascular diseases seems to be decreased, while in coeliac disease an elevated risk for cerebrovascular and cardiovascular diseases was observed. These differing vascular risk profiles between the two manifestations of the same disease merit further investigation.
