Bozorg SR, Lee AR, Mårild K, Murray JA. The Economic Iceberg of Celiac Disease: More Than the Cost of Gluten-Free Food. Gastroenterology 2024; 167:172-182. [PMID: 38670283 DOI: 10.1053/j.gastro.2024.02.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 02/28/2024] [Accepted: 02/29/2024] [Indexed: 04/28/2024]
Abstract
Celiac disease (CeD) is a chronic autoimmune disorder of global relevance, with the potential for acute and long-term complications. However, the economic burden of CeD is rarely considered and largely thought of as limited to the cost of gluten-free food. Fortunately, recent research has shed light on the various societal costs of CeD across the health care continuum. This article summarizes the current evidence on the economic impacts of CeD, which suggest that the societal economic burden of CeD stretches beyond the cost of gluten-free food. This review provides ample evidence of larger but hidden costs related to excess health care use for complications and comorbidities, as well as reduced productivity. Although significant advances are expected in the management of CeD, their effect on the economic burden of CeD remain uncertain. The aim of this review was to inform stakeholders across society and contribute to improved policies to support patients with CeD.

Abstract
Celiac disease is a global disease requiring genetic susceptibility and gluten exposure to trigger immune-mediated enteropathy. The effect of the degree of gluten-containing grain availability on celiac disease prevalence is unknown. Our objective was to compare country-based gluten availability to celiac prevalence using a systematic literature review. We searched MEDLINE, Embase, Cochrane, and Scopus until May 2021. We included population-based serum screening with confirmatory testing (second serological study or small intestine biopsy) and excluded specific, high-risk, or referral populations. We determined country-specific gluten availability using the United Nations food balance for wheat, barley, and rye. Human leukocyte antigen (HLA) frequencies were obtained from allelefrequencies.net. The primary outcome was association between gluten-containing grain availability and celiac disease prevalence. Generalized linear mixed models method with Poisson's link was used for analysis. We identified 5641 articles and included 120 studies on 427 146 subjects from 41 countries. Celiac disease prevalence was 0-3.1%, median 0.75% (interquartile range 0.35, 1.22). Median wheat supply was 246 g/capita/day (interquartile range 214.8, 360.7). The risk ratio (RR) for wheat availability on celiac disease was 1.002 (95% confidence interval [CI]: 1.0001, 1.004, P = 0.036). A protective association was seen with barley, RR 0.973 (95% CI: 0.956, 0.99, P = 0.003), and rye, RR 0.989 (95% CI: 0.982, 0.997, P = 0.006). The RR for gross domestic product on celiac disease prevalence was 1.009 (95% CI: 1.005, 1.014, P < 0.001). The RR for HLA-DQ2 was 0.982 (95% CI: 0.979, 0.986, P < 0.001), and that for HLA-DQ8 was 0.957 (95% CI: 0.950, 0.964, P < 0.001). In this geo-epidemiologic study, gluten-containing grain availability showed mixed associations with celiac disease prevalence.

Coeliac Disease Case-Control Study: Has the Time Come to Explore beyond Patients at Risk? Nutrients 2023; 15:nu15051267. [PMID: 36904266 PMCID: PMC10005316 DOI: 10.3390/nu15051267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 02/26/2023] [Accepted: 02/27/2023] [Indexed: 03/08/2023] Open
Abstract
The worldwide prevalence of asymptomatic coeliac disease (CD) is increasing, which is in part due to the routine screening of children with risk factors. Both symptomatic and asymptomatic patients with CD are at risk of long-term complications. The objective of this study was to compare the clinical characteristics of asymptomatic and symptomatic children at the time of CD diagnosis. A case-control study was conducted using data from a cohort of 4838 CD patients recruited from 73 centers across Spain between 2011 and 2017. A total of 468 asymptomatic patients (cases) were selected and matched by age and sex with 468 symptomatic patients (controls). Clinical data, including any reported symptoms, as well as serologic, genetic, and histopathologic data were collected. No significant differences were found between the two groups in most clinical variables, nor in the degree of intestinal lesion. However, the asymptomatic patients were taller (height z-score -0.12 (1.06) vs. -0.45 (1.19), p < 0.001) and were less likely to have anti transglutaminase IgA antibodies ≥ 10 times the upper normal limit (66.2% vs. 758.4%, p = 0.002). Among the 37.1% of asymptomatic patients who were not screened for CD due to the absence of risk factors, only 34% were truly asymptomatic, while the remaining 66% reported non-specific CD-related symptoms. Therefore, expanding CD screening to any child who undergoes a blood test could reduce the burden of care for some children, as many of those considered asymptomatic reported non-specific CD-related symptoms.

Abstract
BACKGROUND Both undiagnosed celiac disease and some chronic childhood diseases are associated with lower academic achievement. However, there is little knowledge of achievements in those diagnosed with celiac disease. Our aim was to investigate school achievements in upper secondary school among Swedish adolescents with celiac disease. METHODS We performed a retrospective cohort study using register data. We analyzed choice of upper secondary school program, completion of upper secondary school including achievements of basic eligibility for college/university, and final grade in individuals with celiac disease diagnosed before 15 years of age, born 1991-97. We compared with the Swedish population of the same birth years. Analyses were adjusted for sex, year of birth, living region at 17 years of age, and parental education as well as income. RESULTS The cohort included 734 074 individuals, whereof 3 257 (62% females) with celiac disease. There was no significant difference in choice of upper secondary school program. No significant difference was found in completion or achieving basic eligibility for college/university in adjusted analyses. The mean final grade in the celiac disease group was 13.34 (standard deviation 4.85) compared to 12.78 (standard deviation 5.01) in the reference population (p < 0.001), out of a maximum of 20. The effect of celiac disease on final grade remained in adjusted analyses (p = 0.012). CONCLUSIONS We found that diagnosed celiac disease does not negatively affect school achievements in upper secondary school. This finding suggests the diagnosis, treatment and follow-up programs of celiac disease could reverse potential deleterious academic processes.

Abstract
Objective: At present, there is no reliable indicator for dietary compliance and disease severity in patients with celiac disease (CD). The aim of this study is to evaluate mean platelet volume (MPV) level as a biomarker for detection of disease activation, dietary adherence, and assessment of disease severity. Methods: Eighty-one patients with CD and 50 healthy subjects were enrolled in this study. The diagnosis of CD was established by both positive antibodies against endomysium or gliadin and histopathological criteria (lymphocytic infiltration and total villous atrophy in duodenal biopsies). Results: MPV was observed to be significantly higher among CD patients when compared to healthy controls (8.14±0.26 fL vs. 7.82±0.29 fL and p=0.001). Overall dietary adherence rate was 72.8% (58/81 CD patients). After induction of a gluten-free diet, the MPV was significantly lower in the dietary adherent group than non-adherent patients (7.86±0.17 fL vs. 8.07±0.30 fL and p=0.001). The increase of MPV was correlated with Marsh classification (Marsh 3 active CD vs. Marsh 2 active CD vs. Marsh 1 active CD; 8.32±0.27 fL vs. 8.12±0.19 fL vs. 7.98±0.19 fL; p=0.004 and p=0.009). Conclusion: Based on these data, we believe that increased MPV can provide additional benefit to screening in patients with CD. It can indicate the activation of the disease and adherence to the diet.

Abstract
OBJECTIVES A gluten-free (GF) diet is the primary treatment for celiac disease (CD). Gluten is used in schools, particularly in early childhood, art, and home-economics classrooms. This study aimed to measure gluten transfer from school supplies to GF foods that a child with CD may eat. Also, to measure efficacy of washing techniques to remove gluten from hands and tables. METHODS Five experiments measured potential gluten cross-contact in classrooms: Play-Doh (n = 30); baking project (n = 30); paper mâché (n = 10); dry pasta in sensory table (n = 10); cooked pasta in sensory table (n = 10). Thirty participants ages 2 to 18 were enrolled. Following activities, gluten levels were measured on separate slices of GF bread rubbed on participant's hands and table surfaces. Participants were assigned 1 of 3 handwashing methods (soap and water, water alone, or wet wipe). Repeat gluten transfer measurements were taken from hands and tables. Gluten measurements made using R-Biopharm R7001 R5-ELISA Sandwich assay. RESULTS Paper mâché, cooked pasta in sensory tables, and baking project resulted in rates of gluten transfer far greater than the 20 ppm threshold set by Codex Alimentarius Commission. Play-Doh and dry pasta, however, resulted in few gluten transfers to GF bread >20 ppm. Soap and water was consistently the most effective method for removing gluten, although other methods proved as effective in certain scenarios. CONCLUSIONS The potential for gluten exposure at school is high for some materials and low for others. For high-risk materials, schools should provide GF supplies and have a robust strategy to prevent gluten cross-contact with food.

Diagnosing Celiac Disease: Towards Wide-Scale Screening and Serology-Based Criteria? Gastroenterol Res Pract 2019; 2019:2916024.

Abstract
Celiac disease is one of the most common food-related chronic disorders in children. Unfortunately, this multifaceted disease is challenging to recognize and remains markedly underdiagnosed. Screening of either known at-risk groups or even the whole population could increase the suboptimal diagnostic yield substantially. Many recent guidelines recommend screening of at least selected risk groups, but more wide-scale screening remains controversial. The increasing prevalence of celiac disease and the development of autoantibody assays have also led to a gradual shift in the diagnostics towards less invasive serology-based criteria in a subgroup of symptomatic children. The main open questions concern whether these criteria are applicable to all countries and clinical settings, as well as to adult patients. On the other hand, widening screening and the mistaken practice of initiating a gluten-free diet before the appropriate exclusion of celiac disease increase the number of borderline seropositive cases, which may also challenge the classical histopathological diagnostics. Sophisticated diagnostic methods and a deeper understanding of the natural history of early developing celiac disease may prove useful in these circumstances.

Abstract
AIM Coeliac disease is a common but markedly under-diagnosed condition, which may lead to serious long-term complications if untreated. Both the diagnostic yield and true incidence have significantly increased during the last few decades and it is now one of the most common chronic gastrointestinal conditions in children. The aim of this review was to summarise the current concepts on screening for coeliac disease in children and adolescents. METHOD We conducted a non-systematic literature review of papers published about coeliac disease screening since the year 2000. RESULTS Our review showed that the diagnostic yield could be significantly improved by screening for at-risk groups, or even the whole population, but these approaches remain controversial. Evidence suggests that screening for certain high-risk groups could be beneficial, but untargeted mass screening is not currently recommended. However, whether the benefits of an early diagnosis would overcome the challenges of lifelong dietary treatment, especially in asymptomatic individuals who consider themselves healthy, are unclear. CONCLUSION There is moderate evidence that screening certain at-risk groups for coeliac disease could be beneficial, but more studies in different settings are needed before large-scale population screening can be recommended.

Abstract
Background The diagnostic yield of coeliac disease could be improved by screening in at-risk groups, but long-term benefits of this approach are obscure. Objective To investigate health, quality of life and dietary adherence in adult coeliac patients diagnosed in childhood by screening. Methods After thorough evaluation of medical history, follow-up questionnaires were sent to 559 adults with a childhood coeliac disease diagnosis. The results were compared between screen-detected and clinically-detected patients, and also between originally asymptomatic and symptomatic screen-detected patients. Results In total, 236 (42%) patients completed the questionnaires a median of 18.5 years after childhood diagnosis. Screen-detected patients (n = 48) had coeliac disease in the family and type 1 diabetes more often, and were less often smokers and members of coeliac societies compared to clinically-detected patients, whereas the groups did not differ in current self-experienced health or health concerns, quality of life or dietary adherence. Screen-detected, originally asymptomatic patients had more anxiety than those presenting with symptoms, whereas the subgroups were comparable in other current characteristics. Conclusion Comparable long-term outcomes between screen-detected and clinically-detected patients support risk-group screening for coeliac disease. However, asymptomatic patients may require special attention.

Abstract
AIM: To determine celiac disease (CD) prevalence and associated manifestations or risk factors in healthy adult Emiratis.
METHODS: It is a cross-sectional prospective study, recruiting 1197 (573 women and 624 men) healthy Emiratis between September 2007 and April 2008 among those who went to Al Ain Hospital to undertake the prenuptial examination. Test for anti-tissue transglutaminase (tTG) IgA antibodies was used for CD diagnosis. Subjects with positive results in the anti tTG antibodies assay were also tested for anti-endomysial (EMA) IgA antibodies. A structured interview was used to collect basic demographic and clinical recall data including: information on name, contact address, age, gender, education status, previous diagnosis of CD, diagnosis of CD in 1st degree relatives and history of “chronic diarrhea, anemia, headache, hepatitis, diabetes, tumor, and thyroid disorder”.
RESULTS: Fourteen blood samples (1.17%; 14/1197) were seropositive for CD. The latent CD seropositive patients were 13 women and 1 man and therefore the seroprevalence of CD was 1:86 (14/1197) for adult Emiratis: 1:44 (13/573) for women and 1:624 for men. Binary logistic regression revealed that history of chronic anemia (crude OR = 7.09; 95%CI: 2.32-21.61; P = 0.003) and being a woman (OR = 14.46; 95%CI: 1.89-110.91; P = 0.001) were associated with CD seropositivity. Whereas, the thyroid disorder showed a positive association with CD seropositivity that approach statistical significance (OR = 11.30; 95%CI: 1.32-96.95; P = 0.09) and therefore was included in the multiple logistic regression analysis, which showed that CD seropositivity is independently associated only with history of chronic anemia (OR = 4.58; 95%CI: 1.45-14.48; P = 0.01) and being a woman person (OR = 10.47; 95%CI: 1.33-82.14; P = 0.026).
CONCLUSION: Compared to men the CD seroprevalence among women was remarkably higher. The CD association with women and chronic anemia is of importance from a public health perspective.

Abstract
BACKGROUND AND AIM Socioeconomic position and education are strongly associated with several chronic diseases, but their relation to coeliac disease is unclear. We examined educational level and socioeconomic position in patients with coeliac disease. METHODS We identified 29,096 patients with coeliac disease through biopsy reports (defined as Marsh 3: villous atrophy) from all Swedish pathology departments (n=28). Age- and sex-matched controls were randomly sampled from the Swedish Total Population Register (n=145,090). Data on level of education and socioeconomic position were obtained from the Swedish Education Register and the Occupational Register. We calculated odds ratios for the risk of having coeliac disease based on socioeconomic position according to the European Socioeconomic Classification (9 levels) and education. RESULTS Compared to individuals with high socioeconomic position (level 1 of 9) coeliac disease was less common in the lowest socioeconomic stratum (routine occupations=level 9 of 9: adjusted odds ratio=0.89; 95% confidence interval=0.84-0.94) but not less common in individuals with moderately low socioeconomic position: (level 7/9: adjusted odds ratio=0.96; 95% confidence interval=0.91-1.02; and level 8/9: adjusted odds ratio=0.99; 95% confidence interval=0.93-1.05). Coeliac disease was not associated with educational level. CONCLUSIONS In conclusion, diagnosed coeliac disease was slightly less common in individuals with low socioeconomic position but not associated with educational level. Coeliac disease may be unrecognised in individuals of low socioeconomic position.

Abstract
Intestinal T cells from gluten sensitivity/celiac disease patients respond to a heterogeneous array of peptides. Our study extended this heterogeneity to humoral immune response to various wheat proteins and peptides in patients with gluten sensitivity or Crohn's disease. IgG and IgA antibodies in sera from those patients and healthy control subjects were measured against an array of wheat antigens and peptides. In gluten-sensitive patients, IgG reacted most against transglutaminase, prodynorphin, wheat extract, and α-, γ-, and ω-gliadin; IgA reacted most against wheat then transglutaminase, glutenin, and other peptides. In the sera of Crohn's disease patients, IgG reacted most against wheat and wheat germ agglutinin then transglutaminase, prodynorphin, α-, and γ-gliadin; IgA reacted foremost against prodynorphin then transglutaminase and α-gliadin. These results showed a substantial heterogeneity in the magnitude of IgG and IgA response against various wheat antigens and peptides. Measurements of IgG and IgA antibodies against such an array of wheat peptides and antigens can enhance the sensitivity and specificity of serological assays for gluten sensitivity and celiac disease and may also detect silent celiac disease or its overlap with inflammatory bowel disease.

Long-term deterioration of quality of life in adult patients with celiac disease is associated with treatment noncompliance. Dig Liver Dis 2010; 42:685-91. [PMID: 20399159 DOI: 10.1016/j.dld.2010.03.004] [Citation(s) in RCA: 85] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2009] [Revised: 03/01/2010] [Accepted: 03/08/2010] [Indexed: 02/06/2023]
Abstract
BACKGROUND Deterioration of quality of life in the long term has been suggested for celiac disease patients on a gluten-free diet. AIMS To determine long-term quality of life of celiac disease patients and to assess the benefits of gluten-free diet compliance. PATIENTS We prospectively evaluated 53 newly diagnosed adult celiac disease patients. METHODS The Short Form 36 Health Survey, the Gastrointestinal Symptoms Rating Scale and the Beck Depression Inventory were employed at the time of diagnosis, 1 year, and beyond 4 years (median: 53 months) on treatment. RESULTS At 1 year, a significant improvement from baseline in quality of life indicators was observed (p<0.001 to p<0.0001) with comparable scores to healthy subjects. At 4 years, the Short Form 36 Health Survey scores (p<0.002 to p<0.0002) and Beck Depression Inventory score (p<0.002) show significant deterioration compare with 1 year. Most scores remained significantly better than those at diagnosis (p<0.03 to p<0.0005). No changes were detected in the Gastrointestinal Symptoms Rating Scale scores. The long-term impairment of quality of life was attributable to the deterioration of most dimensions in patients who were not strictly compliant with the gluten-free diet (p<0.05 to p<0.001). CONCLUSIONS Long-term deterioration of quality of life outcomes after the first year of gluten-free diet was associated with the lack of strict compliance with the diet.

Abstract
OBJECTIVE To describe the clinical picture of patients with coeliac disease (CD) and the change in its presentation over the past decades. STUDY DESIGN Patients with CD were identified and clinical data collected from hospital records over a 6-year period (2000-2005). RESULTS Altogether 197 patients aged 0.6-15.9 (mean 7.2) years were identified. They were found amongst the child population served by the hospital, the mean number of children at age 0.5-16 years was 268 000 during 2000-2005. The presenting symptom amongst the youngest patients (<3 years) was chronic diarrhoea (in 67%), and amongst older patients, abdominal pain. At the time of diagnosis, growth was severely retarded (height <2 SD for age) in 6.6%; mean height was -0.06 SD and weight + 1% for height. After diet treatment for a mean of 6 months, both height and weight increased significantly. Anaemia and iron deficiency were present in 25% and 43% of patients respectively. Intraepithelial T-cell receptor gamma/delta cells were pathologic in all 150 specimens studied. CONCLUSIONS The presentation of CD depends on age. Even when we found six times more patients than during years 1976-1985 in the same hospital, published data on the prevalence of CD suggest that we found only a small minority of children with CD.

Abstract
Complementary and Alternative Medicines (CAM) are used by an extensive number of patients in the UK and elsewhere. In order to understand this pattern of behavior, it is helpful to examine the characteristics of people who use CAM. This narrative review collates and evaluates the evidence concerning the demographic characteristics and health status factors associated with CAM use in community-based non-clinical populations. A systematic literature search of computerized databases was conducted, and published research papers which present evidence concerning associations between CAM use and demographic and health characteristics are discussed and evaluated. The evidence suggests that people who use CAM tend to be female, of middle age and have more education. In terms of their health, CAM users tend to have more than one medical condition, but might not be more likely than non-users to have specific conditions such as cancer or to rate their own general health as poor. The multivariate studies that have been conducted suggest that both demographic and health characteristics contribute independently to CAM use. In conclusion, demographic characteristics and factors related to an individual's health status are associated with CAM use. Future research is needed to address methodological limitations in existing studies.

Abstract
BACKGROUND Celiac disease (CD) is recognized as one of the most common and important autoimmune gastrointestinal disorders affecting children. There is evidence that a diagnosis of CD during childhood improves health outcomes. The increasing prevalence of CD is due to increased awareness of the wide range of extraintestinal symptoms associated with CD. OBJECTIVE To determine whether there has been a temporal increase in the diagnosis of CD associated with an increased diagnosis of children without typical gastrointestinal symptoms at the Stollery Children's Hospital (Edmonton, Alberta). METHODS Patients with biopsy-proven CD diagnosed at the Stollery Children's Hospital from 1998 to 2007, were identified by retrospective chart review. Baseline and follow-up data, including demographics, symptoms, risk factors, anthropometrics and laboratory investigations, were collected. RESULTS An increase in the frequency of diagnosis of CD was noted during the study period, particularly from January 2003 onward. Before January 2003, nine children were diagnosed with CD - all with typical symptoms. Between January 2003 and January 2007, inclusive, 149 children were diagnosed with CD, of whom 46% had absent or atypical symptoms. At follow-up, 96% of patients reported improved symptoms, including 53% of individuals who reported being asymptomatic before diagnosis. CONCLUSIONS In the last four years of the period studied, the number of children diagnosed with CD at Stollery Children's Hospital increased 11-fold. Screening children at risk for CD, and those with atypical presentations, contributed to the increased number of diagnoses. Identification of CD and establishment of lifelong, dietary gluten avoidance during childhood has important health benefits and should be encouraged.

Abstract
BACKGROUND The association between celiac disease (CD) and type 1 diabetes mellitus (DM) is recognized. Most cases of CD in patients with DM are reported to be asymptomatic. OBJECTIVES The objectives of this study were to (1) compare and audit our practice with the published standards for screening for CD in children with DM, (2) characterize the children with DM and biopsy-confirmed CD, in terms of growth and gastrointestinal symptoms, and compare them with children with DM and negative celiac serology, and (3) document the effects of a gluten-free diet (GFD) after 1 year of gastrointestinal symptoms, growth, and insulin requirement. METHOD We performed a retrospective case-note review of 22 children with DM, positive celiac serology +/- biopsy-confirmed CD, and 50 children with DM and negative celiac serology. RESULTS Twenty-two children (3.9% of the total diabetic population) had positive celiac serology on screening, with 17 (3%) having biopsy-confirmed CD. Ninety-four percent of the children had standardized celiac serology testing. At diagnosis of CD, 13 of the 17 biopsy-positive children (76.4%) had > or =1 gastrointestinal symptom. The frequency of gastrointestinal symptoms in negative celiac serology diabetic children was 6% (3 of 50) (P < .0005). Symptoms resolved in all children after introduction of a GFD. A significant improvement in weight SD score (P = .008) and BMI SD score (P = .02) was noted in those compliant with a GFD after 1 year. CONCLUSIONS Children with DM and CD have a higher frequency of gastrointestinal symptoms than their diabetic peers with negative celiac serology and are not truly asymptomatic. Institution of a GFD has a positive effect on nutritional status and symptom resolution in the short-term.

Abstract
BACKGROUND/AIMS Celiac disease (CD) patients are affected in their quality of life (QoL). Our objectives were to assess differences in quality of life of patients according to the clinical presentation at diagnosis, and to determine the time-course impact of a gluten-free diet. PATIENTS/METHODS We prospectively evaluated 132 newly diagnosed adult CD patients and 70 healthy controls using self-administered questionnaires: the Short Form-36 health survey, the Gastrointestinal Symptoms Rating Scale; the Beck Depression Inventory both, at diagnosis and at 3-, 6- and 12-months on treatment. RESULTS At diagnosis, patients with classical symptoms (n=97) exhibited a significantly more pronounced alteration of all items of the three questionnaires than atypical/silent cases (n=35) (p<0.01 to <0.00001). Silent CD patients had even better baseline scores (p<0.05 to <0.00001). Treatment produced a substantial and rapid (3-month) improvement of most outcome measures in classical and atypical patients but not in asymptomatic cases. Both subgroups attained comparable final scores with no differences comparing strictly adherents with partially compliant. CONCLUSIONS Atypical/silent celiac disease patients have a significantly better baseline quality of life than those with classical symptoms. Treatment induces a rapid and significant improvement in symptomatic cases but not in silent patients with all subgroups having similar 1-year scores comparable to healthy controls.

Abstract
BACKGROUND Little is known about perinatal risk factors and coeliac disease. AIM To investigate the relationship between perinatal risk factors and subsequent coeliac disease among offspring. METHODS Record linked abstracts of birth registrations, maternity, in-patient and day case records in a defined population of southern England. RESULTS Using univariate analysis, coeliac disease in the child was associated with maternal coeliac disease (odds ratio = 20.6; 95% CI = 5.04-84.0; based on two cases in both mother and child) and with social class, year of birth, maternal smoking and parity. Multivariate analysis confirmed an increased risk of coeliac disease of 3.79 (95% CI = 1.85-7.79) for classes IV and V compared with I and II, an increased risk of 1.92 (1.06-3.49) for births during 1975-1979 compared with 1970-1974 and an increased risk of 1.80 (1.05-3.09) for 'subsequent' compared with 'first' births. Smoking during pregnancy was no longer associated with coeliac disease. Because numbers were small, maternal coeliac disease was excluded from the multivariate analysis. CONCLUSIONS This study shows increased risks of coeliac disease for manual social classes, births during the late 1970s and 'subsequent' births. Overall, perinatal risk factors seem to have a limited role in the aetiology of coeliac disease in children and young adults.

Abstract
OBJECTIVE To evaluate the feasibility and diagnostic accuracy of screening for coeliac disease by rapid detection of IgA antibodies to tissue transglutaminase performed in primary care. DESIGN District nurses screened 6 year old children using rapid antibody testing of finger prick blood. They also collected capillary blood samples for laboratory determination of IgA and IgG antibodies to endomysium and IgA antibodies to tissue transglutaminase. Children with positive rapid test results were directly sent for biopsy of the small intestine. Setting Primary care in Jász-Nagykun-Szolnok county, Hungary. PARTICIPANTS 2690 children (77% of 6 year olds living in the county) and 120 nurses. MAIN OUTCOME MEASURES Positivity for antibodies to endomysium or transglutaminase in the laboratory and coeliac disease confirmed at biopsy. RESULTS 37 children (1.4%, 95% confidence interval 0.9% to 1.8%) had biopsy confirmed coeliac disease. Only five of these children had been diagnosed clinically before screening. Rapid testing had a 78.1% sensitivity (70.0% to 89.3%) and 100% specificity (88.4% to 100%) for a final diagnosis of coeliac disease by biopsy. Sensitivity was 65.1% (50.2% to 77.6%) and specificity was 100% (99.8% to 100%) compared with combined results of IgA and IgG laboratory tests. Trained laboratory workers detected 30 of the 31 newly diagnosed IgA competent patients with the rapid test kit used blindly. Median time to biopsy after a positive rapid test result was significantly shorter (20 days, range 4-148) than after a positive laboratory result (142 days, 70-256; P<0.001). Children with coeliac disease detected at screening were smaller and had worse health status than their peers but they improved on a gluten-free diet. CONCLUSIONS A simple rapid antibody test enabled primary care nurses to detect patients with coeliac disease in the community who were not picked up in clinical care. Extra training is needed to improve sensitivity.

Abstract
INTRODUCTION Celiac disease can be treated by following a strict gluten-free diet for life. If properly followed, the diet resolves symptoms and nutritional deficiencies. It is generally recommended that individuals with celiac disease have careful long-term follow-up. However, it is not clear which elements of disease status evaluation, laboratory investigations and self-management support should be included in follow-up. OBJECTIVES To examine the current practice guidelines and recommendations regarding follow-up of individuals with celiac disease. METHODS Guidelines issued by gastroenterological societies and associations, and recommendations by experts were retrieved using Medline and other Internet search engines. RESULTS Practice guidelines were available from the American Gastroenterological Association; the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition; the National Institutes of Health Consensus Development Conference 2004; the World Gastroenterology Organization; the British Society for Gastroenterology and the United Kingdom-based Primary Care Society for Gastroenterology. Most guidelines recommended a scheduled annual review and regular measurements of body mass index. The British Society for Gastroenterology recommended dietary review only at times of stress, while others recommended dietary review with a nutritionist. All associations recommended serial tissue transglutaminase antibody testing. The American Gastroenterological Association and the Primary Care Society for Gastroenterology recommended annual hemoglobin, ferritin and folate checks. One guideline recommended annual hemoglobin, electrolyte, calcium, albumin, ferritin, folate, fat-soluble vitamin, liver function test, parathyroid hormone and bone density measurements (approximately $400 per patient). CONCLUSIONS The current practice guidelines regarding the follow-up of patients with celiac disease varied greatly in their recommendations and many were not evidence-based. Prospective studies are required to develop rational, cost-effective and risk-stratified guidelines for long-term follow-up of these patients.

Abstract
Celiac disease is an immunological disorder whose best-known manifestations are gastrointestinal symptoms. However, early joint manifestations are common and frequently overlooked features of celiac disease. We report a case in which unexplained inflammatory polyarthralgia and iron-deficiency anemia led to the diagnosis of celiac disease. Autoimmune thyroiditis was also a feature. Early diagnosis and treatment of celiac disease protect patients against complications such as digestive neoplasis. A simple and rapid tool for achieving the early diagnosis is the measurement of the serum of anti-gliadin, anti-endomysial and anti-tissue transglutaminase antibodies. However, a duodenal biopsy remains the only means of making the definitive diagnosis of celiac disease.

Abstract
BACKGROUND Celiac disease (CD) is one of the most common lifelong disorders in western countries. However, most cases remain currently undiagnosed in North America, mostly due to poor awareness of CD by primary care physicians. OBJECTIVES The aims of this study were (a) to determine whether an active case-finding strategy in primary care could increase the frequency of CD diagnosis and (b) to determine the most common clinical presentations of the condition. METHODS This was a multicenter, prospective study involving adult subjects during the years 2002-2004, attending one of the participating practices. All individuals with symptoms or conditions known to be associated with CD were tested for immunoglobulin A anti-transglutaminase (tTG) antibodies, and those with elevated anti-tTG were subsequently tested for IgA antiendomysial antibodies (EMA). All subjects who were positive for EMA were advised to undergo an intestinal biopsy and HLA typing. RESULTS The study group included 737 women and 239 men, with a median age of 54.3 yr. A positive anti-tTG test was found in 30 out of 976 investigated subjects (3.07%, 95% CI 1.98-4.16). CD was diagnosed in 22 patients (18 women, 4 men). The most frequent reasons for CD screening in these 22 cases were bloating (12/22), thyroid disease (11/22), irritable bowel syndrome (7/22), unexplained chronic diarrhea (6/22), chronic fatigue (5/22), and constipation (4/22). The prevalence of CD in the serologically screened sample was 2.25% (95% CI 1.32-3.18). The diagnostic rate was low at baseline (0.27 cases per thousand visits, 95% CI 0.13-0.41) and significantly increased to 11.6 per thousand visits (95% CI 6.8-16.4, P < 0.001) following active screening implementation. CONCLUSIONS This study demonstrates that an active case-finding strategy in the primary care setting is an effective means to improve the diagnostic rate of CD in North America.

Abstract
OBJECTIVE A screening program was proposed for the village of Carcare (population 5700), located in a region of Italy with an apparently low prevalence of coeliac disease (CD): only 1 patient diagnosed out of 2557 inhabitants. The study group comprised 1002 individuals (568 F, 434 M, age range 13-90 years) recruited from blood donors, secondary school pupils and people referred to the local outpatient facilities for routine blood chemistry. MATERIAL AND METHODS Total IgA, IgA anti-tissue transglutaminase (tTG) (ELISA, recombinant human antigen) and IgA antiendomysium (EMA) (IFI, umbilical cord substrate) antibodies were measured in the serum of all participants. All patients with IgA deficiency were investigated for IgG tTG antibodies, and in the case of disagreement between tTG and EMA, they were typed for HLA DQ2-DQ8 haplotypes. RESULTS Thirteen subjects were positive and 988 negative for autoantibodies (3/988 had IgA deficiency). One serum sample was positive for tTG antibodies but negative for EMA. Ten out of 13 positive subjects consented to undergo duodenal biopsy, which invariably produced evidence of CD despite the absence of clinical signs/symptoms. A post-diagnostic clinical investigation provided evidence showing mild iron deficiency (4 subjects) and osteoporosis (2 subjects). After counselling, all subjects accepted a gluten-free diet. CONCLUSIONS The prevalence of CD in the study group was 1:100 (1.0%; 95% CI: 0.5-1.8%): this indicates that CD is largely underdiagnosed in Carcare. Our results suggest that the low prevalence of CD observed in some regions is likely to be due to underdiagnosis.

Abstract
Celiac disease is an autoimmune disorder that occurs in genetically predisposed individuals as the result of an immune response to gluten. It is present in approximately 1% of the population. Diarrhea has become a less common mode of presentation (<50% of cases) than it once was. Other presentations include iron-deficiency anemia, osteoporosis, dermatitis herpetiforme, and neurologic disorders, mainly peripheral neuropathy and ataxia. Arthritis is commonly found in patients with celiac disease when systematically sought. Overall, autoimmune diseases occur more frequently (three to ten times more) in those with celiac disease than in the general population. A gluten-free diet is the standard of treatment, although its effect on some of the extraintestinal manifestations remains to be determined.
