The Role of Exposomes in the Pathophysiology of Autoimmune Diseases I: Toxic Chemicals and Food. PATHOPHYSIOLOGY 2021; 28:513-543.

Abstract
Autoimmune diseases affect 5–9% of the world’s population. It is now known that genetics play a relatively small part in the pathophysiology of autoimmune disorders in general, and that environmental factors have a greater role. In this review, we examine the role of the exposome, an individual’s lifetime exposure to external and internal factors, in the pathophysiology of autoimmune diseases. The most common of these environmental factors are toxic chemicals, food/diet, and infections. Toxic chemicals are in our food, drink, common products, the air, and even the land we walk on. Toxic chemicals can directly damage self-tissue and cause the release of autoantigens, or can bind to human tissue antigens and form neoantigens, which can provoke autoimmune response leading to autoimmunity. Other types of autoimmune responses can also be induced by toxic chemicals through various effects at the cellular and biochemical levels. The food we eat every day commonly has colorants, preservatives, or packaging-related chemical contamination. The food itself may be antigenic for susceptible individuals. The most common mechanism for food-related autoimmunity is molecular mimicry, in which the food’s molecular structure bears a similarity with the structure of one or more self-tissues. The solution is to detect the trigger, remove it from the environment or diet, then repair the damage to the individual’s body and health.

Abstract
Celiac disease (CD) is a systemic, immune mediated and genetically determined small intestinal disorder characterized by intolerance to dietary gluten that generally presents with gastrointestinal symptoms in young children and extra-intestinal manifestations. Furthermore, there is close association between CD and endocrine diseases, including diabetes, autoimmune thyroid diseases, growth and pubertal disorders, etc. probably due to the presence of a common genetic predisposition. The present review aims to highlight and give more insight to the endocrine changes in CD, especially when there are few or no gastrointestinal symptoms and to emphasize on screening opportunities in some endocrine diseases.

Abstract
Celiac disease (CD) is an autoimmune disorder of the small intestine with highly variable clinical presentation and frequently associated with various immune-mediated diseases. Among these immune-mediated diseases, atopy has been found frequently in individuals with CD. We aimed to study the prevalence of CD in Estonian children with atopic dermatitis (AD), a common multifactorial chronic inflammatory skin disease. We recruited 351 consecutive children with active AD (mean age 5.8 yrs, 57.6% boys) at Tallinn Children's Hospital, Estonia. Sera of all patients were tested for total serum immunoglobulin (Ig) A, for IgA- and IgG-type autoantibodies to tissue transglutaminase (IgA-anti-TG2, IgG-anti-TG2) and to deamidated gliadin peptides (IgA-anti-DGP, IgG-anti-DGP). The diagnosis of CD was confirmed histologically by small intestine biopsy according to the European Society of Paediatric Gastroenterology, Hepatology and Nutrition diagnostic criteria. IgA deficiency was detected in nine patients with AD (2.6%), none of whom had IgG-anti-TG2 or IgG-anti-DGP seropositivity. IgA-anti-TG2 positivity was found in 4 (1.1%), IgG-anti-TG2 positivity in 2 (0.6%), IgA-anti-DGP positivity in 11 (3.1%), and IgG-anti-DGP in 10 (2.8%) patients. Celiac disease was confirmed in five (1.4%) patients with AD (95% confidence interval 0.46, 3.32) and all were histologically characterized as Marsh IIIa-IIIc stages and two presented with silent CD. In AD patients, CD prevalence was more than four times as high as in previously studied randomly selected schoolchildren in Estonia. Two patients with AD diagnosed with CD had no symptoms indicative of CD, in spite of extensive histologic changes in the small intestine mucosa. Therefore our study emphasizes the need for evaluating the cost-effectiveness of screening individuals with AD for CD in time to prevent long-term complications.

Abstract
OBJECTIVE Celiac disease is a permanent enteropathy caused by the ingestion of gluten, which leads to an immunemediated inflammation of the small intestine mucosa. The prevalence of celiac disease varies among different nations and ethnic backgrounds, and its diversity is determined by genetic and environmental factors. São Paulo city is one of the largest cities in the world, with a vast population and an important history of internal migratory flow from other Brazilian regions, as well as immigration from other, primarily European, countries, resulting in significant miscegenation. The aim of the present study was to estimate the prevalence of adults with undiagnosed celiac disease among blood donors of São Paulo by collecting information on the ancestry of the population studied. METHODS The prevalence of celiac disease was assessed by screening for positive IgA transglutaminase and IgA endomysium antibodies in 4,000 donors (volunteers) in the Fundação Pró-Sangue Blood Center of São Paulo, São Paulo, Brazil. The antibody-positive subjects were asked to undergo a small bowel biopsy. RESULTS Of the 4,000 subjects, twenty-four had positive tests, although both antibody tests were not always concordant. For example, ten subjects were positive for IgA tissue transglutaminase only. In twenty-one positive patients, duodenal biopsies were performed, and the diagnosis of celiac disease was confirmed in fourteen patients (Marsh criteria modified by Oberhuber). In this group, 67% claimed to have European ancestry, mainly from Italy, Portugal and Spain. CONCLUSION The prevalence of celiac disease is at least 1:286 among supposedly healthy blood bank volunteers in São Paulo, Brazil.

Abstract
Recurrent aphthous stomatitis (RAS) is the most common idiopathic intraoral ulcerative disease in the USA. Aphthae typically occur in apparently healthy individuals, although an association with certain systemic diseases has been reported. Despite the unclear etiopathogenesis, new drug trials are continuously conducted in an attempt to reduce pain and dysfunction. We investigated four controversial topics: (1) Is complex aphthosis a mild form of Behçet's disease (BD)? (2) Is periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome a distinct medical entity? (3) Is RAS associated with other systemic diseases [e.g., celiac disease (CD) and B12 deficiency]? (4) Are there any new RAS treatments? Results from extensive literature searches, including a systematic review of RAS trials, suggested the following: (1) Complex aphthosis is not a mild form of BD in North America or Western Europe; (2) Diagnostic criteria for PFAPA have low specificity and the characteristics of the oral ulcers warrant further studies; (3) Oral ulcers may be associated with CD; however, these ulcers may not be RAS; RAS is rarely associated with B12 deficiency; nevertheless, B12 treatment may be beneficial, via mechanisms that warrant further study; (4) Thirty-three controlled trials published in the past 6 years reported some effectiveness, although potential for bias was high.

Abstract
Background Gluten sensitive enteropathy (GSE) is an autoimmune enteropathy triggered by the ingestion of gluten-containing grains in susceptible individuals. Recurrent aphthous stomatitis (RAS) may be the sole manifestation of GSE. The aim of this study was to determine the prevalence of gluten sensitivity enteropathy (GSE) in a large group of patients with RAS and assess the efficacy of gluten free diet (GFD) on the improvement of aphthous lesions in those who were diagnosed with GSE. Methods Two hundred and forty seven patients with RAS were included. The patients had at least three aphthous attacks per year. Patients were screened by IgA anti-endomysial antibody (EMA), IgA anti tissue transglutaminase (TTG) and serum IgA level. Those with a positive serology underwent endoscopic biopsies of the duodenal mucosa and patients with negative serology were excluded. The diagnosis of GSE was based on a positive serological test and abnormal duodenal histology. For patients with GSE, gluten free diet was recommended. Results Six out of 247 RAS patients had positive TTG test alone, and one had positive EMA and TTG. All 7 patients with positive serologic tests underwent duodenal biopsies. Histological findings were compatible with GSE in all of them (Marsh I in four patients, Marsh II in two patients and Marsh IIIB in one another.). The mean age of GSE patients was 27.42 ± 10.56 (range, 13 to 40) years old. They were suffering from RAS for an average duration of 4.5 years. All of the 7 GSE patients had not responded to the routine anti-aphthae medications, including topical corticosteroids, tetracycline and colchicine. Four patients who adhered to a strict gluten-free diet showed noticeable improvement in their aphthous lesions over a period of 6 months. Conclusion A significant minority (e.g. 2.83%) of RAS patients have GSE. This could be compared with the 0.9% prevalence of GSE in the general population of Iran. This study suggests that evaluation for celiac disease is appropriate in patients with RAS. Additionally, the unresponsiveness to conventional anti-aphthae treatment could be an additional risk indicator.

Abstract
The diagnosis of coeliac disease has traditionally depended on symptoms and intestinal biopsies; nowadays, the diagnosis has been expanded to include an array of serological markers and subtle microscopic lesions. The most important advance in classifying mucosal lesions in coeliac disease was forwarded by Marsh (1992), who provided the biological explanation of how the small bowel reacts to a variety of environmental antigenic challenges including gluten. In the modified version of this classification (Arnhem 1998-1999) autoantibodies have integrated into Marsh's histopathological scheme. As a large part of the coeliac 'iceberg' remains unrecognised, the difficulties in diagnosis continue to challenge clinicians and researchers. Advances in immuno-histochemistry and discovery of the other sensitive markers have acquainted us with so-called Microscopic enteritis, the distinctive subtle abnormalities behind the atypical gluten sensitivity symptoms that often remain unrecognised. Current diagnostic pathways do not always include facilities for looking for this common histological feature in atypical cases. This is essential since improving of the detection rate has been shown to be directly proportional to recognition of cases with milder or minimal mucosal abnormalities. In this revision, we will define and characterise microscopic enteritis as the entity behind a wide range of unexplained gastrointestinal symptoms. Screening for this subtle and distinctive presentation in small bowel pathology will open a new prospect in recognising the most common but unrecognised atypical forms of symptomatic gluten related enteropathies.

Abstract
BACKGROUND While gluten-free diet is an effective treatment for coeliac disease, the need for and goals of long-term management of patients are poorly defined. AIM To review systematically the complications and associations of coeliac disease, to identify potential risk factors, to define ways of assessing risk factors and to provide a strategy for management. METHODS Review of medical literature from 1975. RESULTS There is an increasing list of potential complications and/or conditions associated with coeliac disease, in particular, autoimmune disease, malignancy and bone disease. Risk factors that may predict or influence long-term outcomes include genetic susceptibility, environmental factors predominantly gluten ingestion, persistent small intestinal inflammation/injury and nutritional deficiencies. Genotyping of patients is yet to have an established clinical role in long-term management. Assessment of adherence to the gluten-free diet largely relies upon skilled dietary history, but the ultimate test is duodenal histopathology, which is the only currently established means of assessing healing. Symptoms, serology or other non-invasive means are poor predictors of healing and the likelihood of complications. CONCLUSION Evidence (albeit limited) that adherence to a gluten-free diet and mucosal healing prevent and/or ameliorate complications indicates that a planned long-term strategy for follow-up is essential.

Abstract
GOAL Recent studies suggest an increasing prevalence of atypical initial symptoms in patients with celiac disease (CD). The aim of this study was to compare the presenting symptoms of CD at 2 comparable referral institutions in South Florida, and in Ankara, Turkey. We retrospectively reviewed the records of patients with an initial diagnosis of CD by small bowel biopsy during the same (1991 to 2001) 10-year period at Cleveland Clinic Florida and University of Ankara, Turkey. A numerical score was assigned to presenting symptom and signs. RESULTS There were 28 patients in the South Florida group (51% men) and 40 patients in the Turkish group (35% men) (P=NS). The Turkish patients were significantly younger at diagnosis (36+/-2 y vs. US patients 66+/-3 y) (P<0.0001). Typical celiac symptom scores were similar (Turkey 1.1+/-0.2 vs. South Florida 1.3+/-0.3) (P=NS). Atypical symptom scores were significantly higher in the US patients (1.9+/-0.2) versus those from Turkey (1.2+/-0.1) (P<0.01). The Turkish patients were significantly more likely (P<0.01) to present with chronic diarrhea, hypoalbuminemia, and mactocytosis at the time of diagnosis. CONCLUSIONS Although retrospective, this study points to striking differences in the clinical presentation of CD in individuals in South Florida, United States, and Ankara, Turkey, diagnosed during the same time period at both institutions. Turkish patients were younger, and more likely to present with chronic diarrhea, hypoalbuminemia, and microcytosis-as was more commonly seen in the United States in the 1960s and 70s. These findings raise the question of an interplay of demographics with diet and genetics in the presenting symptoms of CD in these 2 distant geographic areas.

Abstract
OBJECTIVE Although the relationship between celiac disease and diabetes mellitus type 1 is well recognized, there are no studies of this association in Brazil. This study aims to identify the prevalence of celiac disease in a group of children with diabetes mellitus type 1 undergoing treatment in the pediatric endocrinology division of a university hospital in Minas Gerais, Brazil. METHODS Immunoglobulin (Ig)A and IgG antigliadin antibodies (enzyme-linked immunoadsorbent assay) were measured in blood collected from 236 children and adolescents with diabetes mellitus type 1. Patients with antigliadin antibodies then had jejunal biopsy and determination of antiendomysial antibodies by indirect immunofluorescence. RESULTS Twenty-one patients had IgA or IgG antigliadin antibodies. Nineteen underwent jejunal biopsy. Six had mucosal alterations compatible with celiac disease; four had nonspecific histologic changes; nine had normal biopsies. Thirteen antigliadin antibody-positive patients were antiendomysial antibody-negative; one antiendomysial antibody-negative patient had celiac disease. The prevalence of celiac disease was 2.6% among 234 patients. CONCLUSIONS Measurement of antigliadin antibodies in patients with diabetes mellitus type 1 helped in the selection of patients to undergo jejunal biopsy. Antiendomysial antibodies were highly specific and moderately sensitive in predicting celiac disease. The prevalence of celiac disease was higher in diabetics than in the general population, suggesting the need for regular screening assessment of diabetic children.

Abstract
Celiac disease (CD) is an autoimmune disease of the small bowel characterized by a strong genetic association with HLA - DQ2 and DQ8. Gluten is the etiological factor and the tissue enzyme transglutaminase (TGase) is its autoantigen. CD is associated with several autoimmune diseases such as type 1 diabetes, systemic lupus erythematous, rheumatoid arthritis, Sjögrens syndrome and autoimmune thyroid diseases. The aim of this study was to investigate the occurrence of serum IgA anti-endomysial and anti-human TGase antibodies in individuals with positive anti-thyroid antibody (ATA). The concordance between these two tests was also evaluated. Anti-endomysial antibodies were positive in 10 out of 456 (2.2%) and anti-human TGase were positive in 14 of 454 (3.1%) individuals with positive ATA. In control subjects they were positive in 1 of 197 (0.5%) and 2 of 198 (1%) for anti-endomysial and anti-human tissue TGase antibodies, respectively. The odds ratio (OR) for the anti-endomysial antibodies was 4.42 and for the anti-human TGase 3.12 in individuals with ATA when compared with controls. An elevated concordance index (k= 0.84) was observed between anti-endomisyal antibodies and anti-human TGase. We conclude that the determination of anti-TGase antibodies is a good test for DC screening.

BACKGROUND There are no available data concerning the incidence and the clinical pattern of coeliac disease in immigrant children coming to Italy from developing countries. AIMS To evaluate the epidemiological and clinical features of coeliac immigrant children coming to Italy. PATIENTS AND METHODS Hospital records of 1917 children diagnosed in 22 Italian Centres from 1999 to 2001 as having coeliac disease were retrospectively reviewed, comparing immigrant patients versus Italian ones. RESULTS 36/1917 (1.9%) coeliac children were immigrant. This prevalence was similar to that of the immigrant children among the whole paediatric population living in Italy. Prevalence was influenced by geographical factors, being higher in Northern Italy (1.7%) and in Central Italy (2.5%) than in Southern-Insular Italy (1.5%), as consequence of a higher proportion of immigrants in these regions. The native areas of the immigrant children were East Europe (15/36), Northern Africa (14/36), Southern Asia (4/36), West Africa (1/36), East Africa (1/36) and the Middle East (1/36). The clinical spectrum and dietary habits in immigrant patients were similar to those of the Italian children. CONCLUSIONS Coeliac disease among the immigrant children coming from developing countries is an emerging problem, and physicians need to be fully aware of it. An important risk factor for coeliac disease in immigrant children appears to be sharing of the same dietary habits with the Italian population. The finding of coeliac disease in children coming from many countries worldwide suggests that coeliac disease is a global public health problem.

Abstract
The aim of the present study was to determine the prevalence of celiac disease in children of short stature and to assess whether some of the routine laboratory examinations performed to determine the cause of short stature could suggest the presence of celiac disease. A total of 106 children of short stature and no gastrointestinal symptoms were studied. An extensive endocrine work-up had been negative for all of them and an additional investigation was performed by measuring the concentration of antiendomysial antibody. Patients who were positive for antiendomysial antibody (> or =1:10) or who exhibited IgA deficiency (less than 5 mg/dl) were referred for an endoscopic intestinal biopsy. We detected a pathological titer of antiendomysial IgA in six of these patients. Five of them showed histological abnormalities compatible with celiac disease and one had normal histology and was considered to have potential celiac disease. The prevalence of celiac disease in the population studied was 4.7% (with another 0.9% of the subjects being considered to have potential celiac disease). The children with celiac disease did not differ in any of the parameters tested when compared to those without celiac disease, though they showed an improvement in growth velocity after treatment with a gluten-free diet. We conclude that it is important to test all children with short stature for celiac disease by measuring antiendomysial IgA.

Abstract
Celiac disease is a permanent intolerance to dietary gluten. Its well known features are abdominal symptoms, malabsorption of nutrients, and small-bowel mucosal inflammation with villous atrophy, which recover on a gluten-free diet. Diagnosis is challenging in that patients often suffer from subtle, if any, symptoms. The risk of clinically silent celiac disease is increased in various autoimmune conditions. The endocrinologist, especially, should maintain high suspicion and alertness to celiac disease, which is to be found in 2-5% of patients with insulin-dependent diabetes mellitus or autoimmune thyroid disease. Patients with multiple endocrine disorders, Addison's disease, alopecia, or hypophysitis may also have concomitant celiac disease. Similar heredity and proneness to autoimmune conditions are considered to be explanations for these associations. A gluten-free diet is essential to prevent celiac complications such as anemia, osteoporosis, and infertility. The diet may also be beneficial in the treatment of the underlying endocrinological disease; prolonged gluten exposure may even contribute to the development of autoimmune diseases. The diagnosis of celiac disease requires endoscopic biopsy, but serological screening with antiendomysial and antitissue transglutaminase antibody assays is an easy method for preliminary case finding. Celiac disease will be increasingly detected provided the close association with autoimmune endocrinological diseases is recognized.
