Celiac Disease In Adolescents Research Articles

Psychological flexibility and celiac disease in adolescents: Understanding adherence and well-being for enhanced care. A rapid narrative review

Abstract Background Psychological flexibility (PF) has been approached as a mediator between health conditions and outcomes by promoting positive responses and healthier behavior repertoires. Purpose This rapid narrative review examines studies exploring the role of PF in influencing celiac disease outcomes among adolescents, with a particular focus on adherence to dietary management practices. Method Online databases were searched for studies exploring possible connections between PF, celiac manifestation, and management presented by adolescents. Selected articles have entered the analysis to highlight whether PF mediates or affects celiac-related outcomes in adolescents. Conclusions Adolescents demonstrate a greater capacity to organize their daily routines effectively while adhering to gluten-free diets. However, the emphasis on PF can significantly impact their social interactions. Although there is much research to be conducted on this possible connection, there are still primary assumptions that support the idea that PF can also be a factor in helping adolescents with celiac disease navigate the challenges of their illness and maintain a quality of life. Healthcare professionals can find value in incorporating elements from supporting therapies, health literacy programs, and health promotion strategies. Furthermore, insights from the review suggest the importance of standardizing interventions and measurements including counseling practices at the primary care level.

Diagnosis, Clinical Presentation and Management of Celiac Disease in Children and Adolescents in Poland

Celiac disease (CD) is a chronic immune-mediated disorder triggered by the ingestion of gluten in genetically predisposed individuals, affecting about 1% of the general population in the developed world. In 2012, the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) recommendations for CD diagnoses in children and adolescents were introduced, allowing the “no-biopsy” approach if certain criteria were met. This approach was also confirmed in the revised guidelines published in 2020. Thus, the aim of this study was to assess—over a one-year period—the clinical presentations and current status of the management of children and adolescents diagnosed with CD in Poland. Medical records of children and adolescents, newly diagnosed with CD in 2022/2023 in three medical centers in Poland, were involved. Gastroenterologists completed the specific anonymous web-based forms developed in the CD SKILLS project, including data routinely assessed at individual visits about the diagnostic approach and clinical presentation of the disease. Our study assessed 100 patients (56% girls) with an age range 1.6–18.0 years. We found that 98% of patients were serologically tested prior to a CD diagnosis and 58% of patients were diagnosed using the “no-biopsy” approach. In the analyzed group, 40% belonged to a known risk group, only 22% had annual screening before the CD diagnosis (the longest for 9 years), and 19% showed no symptoms at the time of the CD diagnosis. Our research confirmed the applicability of the “no-biopsy” approach for the diagnosis of CD in children and adolescents in Poland, and also showed changes in the clinical picture of CD. Moreover, we highlight the need to introduce broad CD serological screening in risk groups of the Polish population.

The Correlation Between Serum Anti-tissue Transglutaminase (Anti-tTG) Antibody Levels and Histological Severity of Celiac Disease in Adolescents and Adults: A Meta-Analysis.

Celiac disease is an autoimmune disorder characterized by a broad spectrum of histological damage to the intestinal mucosa. Comprehension and understanding of the association between anti-tissue transglutaminase (anti-tTG) antibody levels and the histological severity of celiac disease are not well established, prompting the need for meta-analysis. This study aims to offer insights into the diagnostic abilities of anti-tTG antibody levels in determining the histological severity of celiac disease by providing quantitative evidence based on a diverse range of studies. An extensive search was conducted across four electronic research databases to identify primary research articles reporting serum anti-tTG antibody levels in correlation with different Marsh grades, signifying the histological severity of celiac disease. The software tool RevMan 5.4 (the Cochrane Collaboration, London, UK) was used to compile standardized mean differences (SMD) alongside their respective confidence intervals. A total of 13 studies were included in the meta-analysis, with a patient pool of 2505 patients. Marsh grade I and II were found to have higher anti-tTG antibody levels compared to those with grade 0 (SMD 1.50; 95% CI: 1.12, 1.87; p-value <0.00001). Antibody levels were higher in Marsh grade IIIa when compared to both grade 0 (SMD 0.97; 95% CI: 0.67, 1.28; p-value <0.00001) and grade ≤2 (SMD 0.61; 95% CI: 0.44, 0.79; p-value <0.00001). Patients with Marsh IIIb also reported greater anti-tTG levels compared to grade 0(SMD 1.48; 95% CI: 0.99, 1.96; p-value <0.00001) and grade ≤2 (SMD 0.98; 95% CI: 0.79, 1.18; p-value <0.00001). Likewise, Marsh grade ≥IIIc reported high levels of anti-tTG antibodies in comparison with grade 0 (SMD 1.06; 95% CI: 0.72, 1.39; p-value <0.00001) and grade ≤2 (SMD 1.18; 95% CI: 1.02, 1.34; p-value <0.00001). Our meta-analysis revealed a consistent, robust correlation between anti-tTG antibody levels and the histological severity of celiac disease, with a clear trend of increasing antibody levels corresponding to the severity of mucosal damage. Large-scale primary research initiatives are needed to reach definitive conclusions.

Celiac Disease in Syrian Children and Adolescents with Type 1 Diabetes Mellitus: A Cross-Sectional Study

Abstract Introduction Celiac disease (CD) is highly prevalent in patients with type 1 diabetes mellitus (T1DM). However, the rate of CD in Syrian children and adolescents with T1DM is unknown. We aimed to investigate the prevalence and characteristics of CD in our unprivileged rural community. Methods Children and adolescents with T1DM who were regularly followed in a private endocrine clinic in Raqqa City, Syria, were evaluated from October 2018 to November 2021. Screening for CD was performed using either anti-tissue transglutaminase antibodies, antideaminated gliadin antibodies, or endomysial antibodies. Patients with positive results were referred for duodenal biopsy using Marsh classification whenever possible. The prevalence of CD was calculated for both seropositive and biopsy-proven cases. Results Ninety-four patients with T1DM, 51 (54.3%) females, were included. The mean age was 11.6 years, and mean hemoglobin A1c (HbA1C) was 9.2%. All patients were screened for CD. Fourteen patients (14.9%) were positive, and seven (7.4%) performed a duodenal biopsy that proved positive for CD in all cases. CD seropositivity was more common in female than male patients (21.6 vs. 7%, respectively, p-value &lt;0.05). Patients with seropositivity for CD had lower hemoglobin levels compared to seronegative patients, with a mean difference of 0.87 (95% confidence interval: 0.2–1.5; p-value &lt;0.05). There was a statistically significant correlation between hypothyroidism and celiac seropositivity (p-value &lt;0.05). There were no differences in age, weight, height, HbA1C, puberty status, or duration of diabetes between patients with and without CD. No correlation was identified between the incidence of hypoglycemia or diabetic ketoacidosis and the presence of CD. Conclusion In our community, we revealed a high prevalence of CD in Syrian children and adolescents with T1DM. Our results are alarming and point to the need for establishing a national CD registry to prompt physicians for proper screening and early management in high-risk populations.

Prevalence of haplotype DQ2/DQ8 and celiac disease in children with type 1 diabetes

Type 1 diabetes (T1D) and celiac disease (CD) coexist very often. Identification of the human leukocyte antigen (HLA) DQ2/DQ8 can confirm the genetic predisposition to CD. Negative result of this test allows to exclude CD with a high probability. It was suggested that in individuals with higher risk of CD, including T1D patients, the implementation of genetic testing should reduce the number of patients requiring systematic immunological screening. The aim of this study was to analyze the prevalence of different haplotypes predisposing to CD in children and adolescents with previously diagnosed T1D. Material and methods: A retrospective analysis was performed on 166 T1D children (91 girls) in whom HLA DQ2/DQ8 alleles were tested. In 9.6% CD was also diagnosed. Results: In 12.7% both HLA DQ2/DQ8 were negative. In 87.3% patients HLA DQ2 and/or DQ8 was positive, including 27.7% patients with both haplotypes DQ2.5 and DQ8 positive. In all CD patients the disease predisposing alleles were positive, while none of the HLA DQ2/DQ8 negative children were diagnosed with CD. Conclusions: The prevalence of HLA DQ2.5 and the HLA DQ2.5 / HLA DQ8 configuration is higher in patients with T1D, and CD compared to children with T1D alone. The combination of HLA DQ2 and HLA DQ8 most significantly increases the risk of developing CD. The group of HLA DQ2/DQ8 negative patients with improbable CD diagnosis, is relatively small. Most of T1D patients HLA DQ2/DQ8 positive need further regular antibody assessment. In patients with T1D, who are at high risk of developing CD, genetic testing may be considered to select those who require further systematic serological evaluation. Due to its retrospective nature, the study was not registered in the database of clinical trials and the Clinical trial registration number is not available.

13.1 Celiac Disease Associated With MENTAL Illness in Children and Correlated Screening Practices

Celiac disease (CD) and non-celiac gluten sensitivity (NCGS) are associated autoimmune manifestations that can lead to psychiatric and neurological disorders, as well as treatment resistance. Mental illness is often the primary expression of CD or NCGS. Up to 85% of patients with histologically proven CD have no gastrointestinal symptoms. Untreated CD can lead to serious behavioral disorders, including a higher suicide risk. Child and adolescent psychiatrists treat such cases daily but may fail to screen for and/or recognize the association. We examine the literature on mental illness associated with CD and NCGS in the pediatric population to inform screening in psychiatry. A literature search using PubMed, Cochrane, and Google Scholar for CD or NCGS-related psychiatric comorbidities in the pediatric population aged 2 to 22 years using the terms “psychiatric,” “celiac,” “gluten,” “child OR adolescent OR pediatric,” and mental illness to include “depression,” “anxiety,” “mood disorders,” “attention deficit hyperactivity disorder,” “psychosis,” and "eating disorders" located 30 relevant articles (19 cohort studies, 2 observational studies, 2 case-control studies, 4 case reports, and 3 systematic reviews). Mental illness symptoms often precede a diagnosis of CD in children; however, we found only 2 articles on screening practices, limited to eating disorders. One study, a small clinical trial, recommended screening patients with severe anorexia nervosa. Another study, a retrospective chart review, surveyed emergency department visits for patients with eating disorders and did not recommend screening for CD. Conversely, a 2019 systematic review stressed the importance of screening for CD in outpatient psychiatric clinics, because the overall prevalence of psychiatric comorbidities is higher in those with CD or NCGS. CD is a common childhood autoimmune disease, with 1 in 100 children being affected. At least 1 out of 3 cases of CD are undiagnosed, suggesting a higher prevalence of mental health disorders linked to CD than expected. More studies are needed to inform screening practices for CD and NCGS in children and adolescents with mental illness. Understanding this association aids clinicians in diagnostic and treatment clarity and could result in mental illness symptom remission with the gluten-free diet.

The prevalence of celiac disease in Saudi patients with type 1 diabetes mellitus.

BACKGROUND: Celiac disease (CD) is an autoimmune disease that is highly associated with type 1 diabetes mellitus (T1DM). The reported prevalence of CD in patients with T1DM in Saudi Arabia varies and the number of studies is limited.OBJECTIVES: Determine the prevalence of CD diagnosed with anti-tissue transglutaminase (anti-tTG) antibodies or by endoscopic biopsy in adolescents and adults with T1DM.DESIGN: Cross-sectional, retrospective medical record review.SETTING: Tertiary care center.PATIENTS AND METHODS: The study population included adolescents and adults with T1DM who were screened for CD between 2010 and 2019. The study variables included age, sex, age at diagnosis of T1DM, age of positive celiac screening, glycated hemoglobin (HbA1c), total daily insulin dose, frequency of diabetic ketoacidosis (DKA) and other autoimmune diseases.MAIN OUTCOME MEASURES: The prevalence of celiac disease in adolescents and adults with T1DM.SAMPLE SIZE: 539 patients.RESULTS: The prevalence of positive celiac test results was 11.5% (n=62). A small proportion (n=5, 8%) of the positive CD group was diagnosed with T1DM after they tested positive with the celiac screening test. Ten (16%) were diagnosed with T1DM and CD in the same year. The rest of the sample had a positive screening test after being diagnosed with T1DM. There was no statistically significant difference between the CD positive and negative groups for HbA1C, DKA frequency, microvascular complications of diabetes or thyroid disorder. For histopathological confirmation of CD, only 37% (n=23) of the group with a positive screening test underwent endoscopy. In this group, 43% (n=10) had normal endoscopic biopsy findings, 21.7% (n=5) had partial villous atrophy and 34.7% (n=8) had total villous atrophy.CONCLUSIONS: This study highlights the importance of screening for CD in T1DM patients. CD prevalence is high in patients with T1DM, despite the high likelihood of underdiagnosis. Additional studies of different age groups and the use of different study methods are required. In addition, a unified national strategy to diagnose CD in T1DM patients is highly advisable.LIMITATIONS: Retrospective, single-center, few confirmations of CD by intestinal biopsy.CONFLICT OF INTEREST: None.

Clinical Presentation in Children With Coeliac Disease in Central Europe

During the past decades, there has been a shift in the clinical presentation of coeliac disease (CD) to nonclassical, oligosymptomatic, and asymptomatic forms. We assessed clinical presentation of CD in children and adolescents in Central Europe. Paediatric gastroenterologists in 5 countries retrospectively reported data of their patients diagnosed with CD. Clinical presentation was analyzed and the differences among very young (<3 years) and older children and adolescents were studied. Data from 653 children and adolescents (median age 7 years 2 months; 63.9% girls) from Croatia, Germany, Hungary, Italy, and Slovenia were available for the analysis. One fifth (N = 134) of all children were asymptomatic. In symptomatic children, the most common leading symptom was abdominal pain (33.3%), followed by growth retardation (13.7%) and diarrhoea (13.3%). The majority of symptomatic children (47.6%; N = 247) were polysymptomatic. Abdominal pain was the most common symptom in polysymptomatic (66.4%) as well as in monosymptomatic children (29.7%). Comparing clinical presentation of CD in very young children (younger than 3 years) with older children (3 years or older), we found that symptoms and signs of malabsorption were significantly more common in younger (P < 0.001), whereas abdominal pain and asymptomatic presentation were more common in older children and adolescents (both P < 0.001). In children with CD, abdominal pain has become the most common symptom. However, in younger children, symptoms of malabsorption are still seen frequently. This raises a question about the underlying mechanism of observed change in clinical presentation in favour of nonclassical presentation and asymptomatic disease at certain age.

Clinical features of non-classical celiac disease in children and adolescents

Introduction/Objective. Nonclassical celiac disease (CD) is characterized by a very heterogeneous and non-specific clinical presentation. The aim of this study was to determine the basic symptoms and clinical signs of this CD subtype in children and adolescents Methods. The study was based on a sample of 58 children and adolescent, 38 female and 20 male, ages 1.75 to 17.75 (10.01?4.62) years with a nonclassical CD diagnosed according to the European Society for Pediatric Gastroenterology, Hepatology and Nutrition criteria from 1990 and 2012. Results. Except four patients who were between the ages of 1.75 to 2.50 years, all others were older than three years. The main clinical symptoms and signs suggestive of non-classical CD were anemia caused by iron deficiency (48.28%), short stature (34.48%), and intermittent abdominal pain (18.97%), anorexia with stagnation or weight loss (13.79%), and chronic constipation (6.9%). Thirty patients had one symptom or sign of the disease, 15 had two and 13 had three. In addition, 12 patients had dental enamel hypoplasia, 18 sideropenia without anemia and five mild isolated hypertransaminasemia. A gluten-free diet, apart from the dental enamel hypoplasia, has resulted in the withdrawal of all indicators of the disease. Conclusion. The main symptoms and clinical signs of nonclassical CD in children and adolescents were iron deficiency anemia, short stature and intermittent abdominal pain, and less frequently anorexia with stagnation or weight loss and chronic constipation. Excluding dental enamel hypoplasia, a gluten-free diet leads to a complete recovery of the patient.

Atopic Dermatitis Is Associated with Dermatitis Herpetiformis and Celiac Disease in Children

Atopic Dermatitis Is Associated with Dermatitis Herpetiformis and Celiac Disease in Children

Autoimmune and Allergic Disorders are More Common in People With Celiac Disease or on a Gluten-free Diet in the United States.

We analyzed demographics, lifestyle patterns, and clinical characteristics of people with celiac disease (CD) and people without CD avoiding gluten (PWAG) to better understand associations with medical conditions and consumer behavior. Clinical significance of CD and gluten avoidance in the general population is incompletely understood. Recently, a high incidence of CD in adolescents with susceptibility genotypes, similar to other autoimmune or allergic disorders, and regional differences in consumer practices of gluten avoidance were reported. Among 22,277 participants in the National Health and Nutrition Examination Survey 2009-2014, we identified persons with CD by testing CD serology or by both a health care provider diagnosis and adherence to a gluten-free diet. Similarly, PWAG were defined as adherent to a gluten-free diet without a CD diagnosis. Consumer behavior and characteristics of both groups, CD and PWAG were compared with those without these conditions, using survey-weighted generalized logistic regression. Participants with CD considered nutrition very important when grocery shopping and tended to have more constipation and thyroid disease. PWAG tended to spend more money on groceries, purchase organic foods, and check food labels more frequently during grocery shopping. They also reported having more food allergies, asthma, and thyroid disease. Our study confirms that CD and PWAG share comorbidities of autoimmune nature. PWAG had more autoimmune/allergy-related disorders that may be associated with non-celiac gluten sensitivity a self-justifiable reason to be on the diet.

High Incidence of Celiac Disease in a Long-term Study of Adolescents With Susceptibility Genotypes

Little is known about the incidence of celiac disease in the general population of children in the United States. We aimed to estimate the cumulative incidence of celiac disease in adolescents born in the Denver metropolitan area. We collected data on HLA-DR, DQ genotypes of 31,766 infants, born from 1993 through 2004 at St. Joseph's Hospital in Denver, from the Diabetes Autoimmunity Study in the Young. Subjects with susceptibility genotypes for celiac disease and type 1 diabetes were followed up for up to 20 years for development of tissue transglutaminase autoantibodies (tTGA). Outcomes were the development of celiac disease autoimmunity (CDA) or celiac disease. CDA was defined as persistence of tTGA for at least 3 months or development of celiac disease. Celiac disease was defined based on detection of Marsh 2 or greater lesions in biopsy specimens or persistent high levels of tTGA. For each genotype, the cumulative incidence of CDA and celiac disease were determined. To estimate the cumulative incidence in the Denver general population, outcomes by each genotype were weighted according to the frequency of each of these genotypes in the general population. Of 1339 subjects followed up, 66 developed CDA and met criteria for celiac disease and 46 developed only CDA. Seropositivity for tTGA resolved spontaneously, without treatment, in 21 of the 46 subjects with only CDA (46%). The estimated cumulative incidence for CDA in the Denver general population at 5, 10, and 15 years of age was 2.4%, 4.3%, and 5.1%, respectively, and incidence values for celiac disease were 1.6%, 2.8%, and 3.1%, respectively. In a 20-year prospective study of 1339 children with genetic risk factors for celiac disease, we found the cumulative incidence of CDA and celiac disease to be high within the first 10 years. Although more than 5% of children may experience a period of CDA, not all children develop celiac disease or require gluten-free diets.

The Prevalence of Celiac Disease in Children With Arterial Ischemic Stroke.

The association between arterial ischemic stroke (AIS) and celiac disease (CD) has been described in only a few cases in adults and children. We aim to determine the prevalence of CD in children and adolescents with AIS. We investigated serum levels of tissue transglutaminase antibody immunoglobulin (Ig)A and total IgA from 76 children with AIS and in a healthy control group of 102 children. Study participants who were positive for tissue transglutaminase IgA antibodies underwent a duodenal biopsy. A total of 2 patients in the AIS group (2.26%) and 2 in the control group (1.96%) had positive serum tissue transglutaminase antibody (P=0.89; 95% confidence interval, -5.05 to 6.89). Duodenal biopsy confirmed CD in only 1 patient who had AIS. In the present study, children with acute arterial stroke did not exhibit a higher prevalence rate of CD compared with healthy controls. Therefore, the screening test for CD is not a necessary part of the management of AIS in children. However, cases of recurrent AIS could be examined for CD.

Prevalence of celiac disease in Indian children with type 1 diabetes.

Type 1 diabetes (T1D) patients are at an increased risk of having celiac disease (CD). We evaluated the prevalence and clinical profile of CD in children and adolescents with T1D and reviewed the Indian literature to determine prevalence and reasons for variability. In this cross-sectional study, subjects with T1D were prospectively evaluated with a demographic and gastrointestinal (GI) questionnaire, human IgA-tissue transglutaminase (IgA-tTGA), and endoscopic duodenal biopsy in serology positive patients. Studies evaluating prevalence of CD in T1D from India were reviewed. Fourteen (13.6%) of the 103 (52 boys, 13years [2-20]) T1D patients were IgA-tTGA (182U [47-300]) positive and 3.8% (4/103) had villous atrophy on histology. Subjects with T1D and CD (n=4) were younger at onset of T1D (32.5±12.6 vs. 110.5±53.8months; p<0.005) and more often had GI symptoms (pain abdomen [2/4 vs. 6/89; p=0.01], stool frequency of 2-3/day [3/4 vs. 38/89; p=0.004]) than screen negative T1D (n=89). Growth and glycemic control were not different between the groups. In the 7 Indian studies involving 915 children and adults, 13.8% (8% to 17.8%) T1D were serology positive. Prevalence of CD was reported as 6.9% (2.3% to 11.1%), but only 3.1% (2.3% to 4.2%) had villous atrophy on histology. Potential CD and CD were present in 13.6 % and 3.8% children with T1D respectively. T1D with CD have onset of diabetes at younger age and were more often symptomatic than screen negative T1D.

Serologic screening of celiac disease in adolescents.

This study aimed to identify the seroprevalence of celiac disease in adolescents from public schools in the city of Salvador, Bahia. This was a cross-sectional study with probabilistic sample of 1,213 adolescents, aged 11 to 17 years old, of both genders. The body mass index was used to determine the participants' nutritional status based on the percentiles for age and gender recommended by the World Health Organization. Measurement of the anti-human transglutaminase immunoglobulin A (anti-tTG-IgA) antibody was established as the specific screening test for celiac disease, which involved an enzyme-linked immunosorbent assay (ELISA). Descriptive analysis was performed using proportions and means (standard deviation). The female gender prevailed in the sample, and most of the participants had normal weights. The anti-tTG-IgA antibody was positive in 6/1,213 (0.49%) adolescents. The seroprevalence of celiac disease was 0.49% in the investigated adolescents. Further studies are necessary to establish the prevalence of celiac disease in this age range.

Increasing prevalence of coeliac disease in Denmark: a linkage study combining national registries

To determine the prevalence and incidence of diagnosed coeliac disease (CD) in Danish children and adolescents and to describe trends over time. All children with a CD diagnosis registered in the Danish National Patient Registry (DNPR) were included in the study. Data were validated by combining this information with registrations of small-bowel biopsies in the National Registry of Pathology (NRP) and with a selected sample of hospital records. Data were obtained from 1996 to 2010. The prevalence of CD registered in DNPR increased from 43.2 [95% CI 39.3-47.1] to 83.6 [95% CI 78.4-88.7] per 100,000, and the incidence increased from 2.8 [95% CI 1.9-3.9] to 10.0 [95% CI 8.4-12.0] per 100,000; 56% of the children had at least one biopsy compatible with CD registered in NRP. The incidence of biopsy-verified CD increased from 0.8 [95% CI 0.3-1.4] to 6.9 [95% CI 5.4-8.4] per 100,000. The mean age at diagnosis increased from 5.1 [95% CI 3.5-6.6] to 8.1 [95% CI 7.2-9.0] years of age. The proportion of children with associated diseases did not change over time. The prevalence of diagnosed CD in Danish children and adolescents has increased over the last 15 years.

Celiac disease prevalence in children and adolescents with type 1 diabetes from Serbia

The association between celiac disease (CD) and type 1 diabetes mellitus (T1DM) is well known. Up to now, CD prevalence in children and adolescents with T1DM in Serbia has not been reported. The aim of the present study was to determine CD prevalence and its clinical manifestations in patients with T1DM. One hundred and twenty-one patients (70 girls, 51 boys; mean age, 10.8 years) with T1DM (mean duration of diabetes, 3.4 years) and 125 control group participants (75 girls, 50 boys; mean age, 10.4 years) were tested for CD on tissue transglutaminase antibodies (tTG). In seven serologically positive T1DM patients endoscopic small bowel biopsies were taken and examined on histopathology. In all patients with CD and T1DM age, duration of T1DM, height for age, body mass index, glycosylated hemoglobin and clinical symptoms were noted. Nine patients with T1DM were positive on IgA tTG antibodies. In seven of them small bowel biopsy was performed, and all were proven to have CD on histopathology. The prevalence of biopsy-proven CD in children and adolescents with T1DM was significantly higher in the study group compared to controls (5.79%. vs 0.8%, P < 0.05). The significantly higher prevalence of CD in children with type 1 diabetes, in accordance with the large volume of data published in the literature, underlines the need for yearly screening of CD in patients with diabetes in order to promptly start a gluten-free diet when appropriate.

Prevalence of Celiac Disease in Brazilian Children and Adolescents with Type 1 Diabetes Mellitus

A previously unrecognized high prevalence of celiac disease (CD) has been found by screening among European and North American patients with type 1 diabetes mellitus (DM 1). The prevalence of CD among Brazilian children with DM1 is not known. This study was conducted to determine the prevalence of CD in Brazilian children and adolescents with DM 1. One hundred and four children and adolescents with DM 1 (52 males and 52 females; age range 22 months - 19 years) and 105 age and gender-matched control participants were screened for CD using the IgA anti-endomysial antibody test (IgA-EmA) and total serum IgA. A small bowel biopsy was performed in all patients with positive IgA-EmA. Nine of 104 diabetic patients (8.7%) had a positive IgA-EmA. Biopsies were normal in four patients, two had partial or subtotal villous atrophy with elevated intraepithelial lymphocyte (IEL) counts, and three showed partial villous atrophy but with IEL counts under the maximum limit adopted (40 IEL/100 enterocytes). EmA-IgA positive patients had mild, non-specific gastrointestinal complaints including dyspepsia, abdominal pain, flatulence and constipation. All control participants had negative results for IgA-EmA. The prevalence of CD in a group of Brazilian pediatric DM 1 patients was at least 4.8%, a prevalence comparable to European and North American studies. The high prevalence of CD among DM 1 emphasizes the need for routine screening in all countries including Brazil.
