Abstract
INTRODUCTION AND OBJECTIVES Even though the incidence has decreased in recent years, Down syndrome (DS) remains the most common chromosomal disorder today. Despite being a condition with multisystemic involvement, it often tends to affect the head and neck area, making it a frequent reason for consultation with pediatric otolaryngologists or otologists. The purpose of this work is to be one of the first in Spain to characterize and describe the pathology and therapeutic approach typically provided to these patients, analyzing the evolution from a clinical and auditory perspective. MATERIAL AND METHODS We aim to analyze a sample of 16 pediatric patients recruited over the past 24 years, diagnosed with Down syndrome, and experiencing a wide range of diseases affecting the ear and its auditory function. RESULTS 62.50% of the patients were women, whose main reason for seeking specialist care was acute and serous otitis media, accounting for 31.25%. These patients have an indication for treatment for various entities within the otological sphere that usually do not differ from those of a healthy child. However, the evolution and response to treatments can take on a torpid character due to the anatomical characteristics of the ears of these patients. CONCLUSIONS Although the frequency of children with DS in the pediatric otolaryngologist's clinic is decreasing, these patients have a predisposition to ear diseases with auditory repercussions, with variable evolution depending on the disease and the child's intrinsic characteristics.

Abstract
Background: Coeliac disease (CD) is an immune-mediated disorder, with dietary exclusion of gluten the only current treatment. A good knowledge of CD and gluten-free diet (GFD) is essential for those with CD to support effective self-management. Knowledge assessment with a validated tool helps evaluate understanding and knowledge gaps to better tailor educational resources. This study's aim was to perform a systematic review to identify validated CD knowledge assessment tools. Methods: PRISMA guidelines were followed, and searches were carried out in five literature databases. Papers were reviewed for tool development and testing process and assessed against pre-defined criteria for feasibility, validity, and reliability. Results: Twenty-five papers were included in the final analysis. Studies were from 16 countries, with a range of target populations, study designs, and development processes. Eleven reported pilot testing, and five assessed readability. Content validity was assessed in ten papers and formal content validity testing in one. Many tools contained items affecting generalisability outside the region developed. Conclusions: For a CD knowledge assessment tool to be suitable for use, it needs to be well designed, tested, and generalisable. No papers identified satisfied all requirements, thus highlighting a need to develop an appropriate tool.

Abstract
Down syndrome (DS) is a unique genetic disease caused by the presence of an extra copy of chromosome 21, which carries four of the six interferon receptor (IFN-R) genes on its long arm. Recent studies reporting higher levels of interferon-stimulated gene (ISG) expression in primary immune cells studied ex vivo have suggested that the additional copies of the IFN-R genes in DS result in mild interferonopathy. In this review, we analyze the potential clinical and immunological impacts of this interferonopathy in DS. We performed a literature review to explore the epidemiology and risks of celiac disease, type 1 diabetes, thyroid dysfunction, mucocutaneous manifestations, infectious diseases (including COVID-19), and Alzheimer’s disease in individuals with DS relative to the general population with or without iatrogenic exposure to interferons. We analyzed immunophenotyping data and the current experimental evidence concerning IFN-R expression, constitutive JAK-STAT activation, and ISG overexpression in DS. Despite the lack of direct evidence that implicating this mild interferonopathy directly in illnesses in individuals with DS, we highlight the challenges ahead and directions that could be taken to determine more clearly the biological impact of interferonopathy on various immune-related conditions in DS.

Abstract
American Academy of Pediatrics (AAP) guidelines for children with Down syndrome (DS) include assessment for celiac disease (CD), although data to support this recommendation have been inconsistent. We determined the incidence of CD among children with DS in a population-based birth cohort of children born from 1976 to 2000 in Olmsted County, Minnesota. Individuals with karyotype-confirmed DS and CD (using diagnosis codes, positive serology, and duodenal biopsies) were identified. The incidence of CD in DS was compared with the published incidence of CD for Olmsted County residents (17.4 [95% confidence interval = 15.2-19.6] per 100 000 person-years). Among 45 individuals with DS from the birth cohort, 3 (6.7%) were identified with positive celiac serology and confirmatory biopsies at ages 9, 12, and 23 years, for an incidence of 325 per 100 000 person-years. Thus, individuals with DS have more than 18 times the incidence rate of CD compared with the general population, supporting the AAP guidelines.

Abstract
OBJECTIVES Children with Down syndrome have an estimated 6-fold increased risk of developing celiac disease in the United States compared with the general population, yet the determination to screen for celiac disease in this population is not agreed upon. The objectives of this study are to assess the prevalence of celiac disease in children with Down syndrome in our center and compare features from this population identified clinically and through screening. METHODS This is a retrospective chart review of 1317 children with Down syndrome who received treatment at a single institution from 2011 to 2017. All participants (n = 90; 53.3% boys) met inclusion criteria of celiac disease diagnosis between 1 month and 22 years of age and Down syndrome. Clinical details were collected, which included the results from celiac disease screening tests, reason for diagnosis and/or testing, symptoms, nutrition notes, demographics, comorbidities, and outcomes. RESULTS Prevalence of celiac disease in our population of children with Down syndrome ages 3 years or older was 9.8%. Mean age at diagnosis was 9.24 years (SD = 4.98) with an average of 2.85 years (SD ± 3.52) lag from the onset of symptoms to diagnosis for children clinically identified in comparison with 1.69 years (SD ± 2.09) for children identified through routine screening. Eighty-two percentage of clinic patients received a diagnosis of celiac disease because of routine screening compared with clinical testing based on identified symptoms alone. CONCLUSION Our results suggest the need for routine celiac disease screening in children with Down syndrome to improve case-finding and avoid diagnostic delay.

Abstract
STUDY OBJECTIVES To estimate the prevalence of obstructive sleep apnea (OSA) in children with Down syndrome. METHODS Two authors independently searched databases, namely PubMed, MEDLINE, EMBASE, and the Cochrane Review database. The keywords used were "Down syndrome," "Trisomy 21," "OSA," "sleep apnea syndromes," "polysomnography" and "polygraphy." The prevalence of OSA based on apnea-hypopnea index (AHI) greater than 1, 1.5, 2, 5, and 10 event/h was estimated using a random-effects model. Subgroup analyses were conducted for children in different countries, sample size, study year, and risk of bias. Finally, the prevalence of OSA was compared between two types of sleep studies (polysomnography versus polygraphy). RESULTS A total of 18 studies (1,200 children) were included (mean age: 7.7 years; 56% boys; mean sample size: 67 patients). Five studies had low risk of bias, and nine and four studies had moderate and high risk of bias, respectively. The OSA was evaluated through polygraphy in 2 studies, and polysomnography in 16 studies. For children who underwent polysomnography, the prevalences of OSA based on AHI > 1, 1.5, 2, 5, and 10 events/h were 69%, 76%, 75%, 50%, and 34%, respectively. Subgroup analyses revealed no significant difference among all subgroups. Meta-regression showed that AHI > 5 events/h was inversely correlated with age (P < .001). Moreover, the prevalence of OSA based on AHI > 1.5 events/h was lower in polygraphy compared with polysomnography (59% versus 76%, P = .037). CONCLUSIONS OSA is highly prevalent in children with Down syndrome. Prevalence of moderate to severe OSA is higher in younger age.

Abstract
Background The association between Down syndrome and celiac disease has been reported by many studies. However, the prevalence of celiac disease (CD) in Down syndrome (DS) varies considerably across studies (from 0 % to 19 %). The aim of this study was to use meta-analysis to exam the prevalence of CD in patients with DS. Methods A systematic search of English articles from Pubmed, Web of Science and CNKI without year limitation. Data were extracted by two independent observers and pooled using a random effects model by the Comprehensive Meta-Analysis Version 2 software. Results A pooled analysis, based on 31 studies included 4383 individuals, revealed prevalence of biopsy-confirmed CD of 5.8 % (95 % CI = 4.7-7.2 %) in patients with DS. Sub-group analysis showed a slightly higher prevalence of CD in children with DS (6.6 %; 17 studies), than in age mixed samples with both children and adults (5.1 %; 13 studies). In addition, most of the studies included in this meta-analysis were from Europe and America, with the prevalence of celiac disease of 6 % (21 studies) and 5.7 % (6 studies) in DS patients, respectively. Furthermore, meta-regression analysis suggested that proportion of antibody-positive individuals that underwent small intestine biopsy had moderating effect on the outcome of the meta-analysis. Conclusions These results demonstrated that patients (children) with Down syndrome had high prevalence of CD (more than one in twenty). The prevalence is high enough to motivate screening CD in DS children.

Abstract
Various typical and atypical neurological manifestations can be seen as the initial symptoms of celiac disease (CD). We suggest that gluten toxicity is the most suspicious triggering risk factor for probable pathophysiological pathways of neurological involvement in atypical CD. The medical charts of 117 patients diagnosed with atypical CD were retrieved from a tertiary center in Ankara, Turkey. Eight patients reported as having neurologic manifestations as initiating symptoms were evaluated in detail. The initial neurological manifestations of CD in our study included atypical absence, which was reported first in this study, generalized tonic-clonic seizures, complex partial seizures, severe axial hypotonia and down phenotype, multifocal leukoencephalopathy, mild optic neuritis, attention deficit hyperactivity disorder, and short duration headaches. Seizures mostly emphasizing atypical absence could be the initial presentation manifestation of CD, first described in this literature. Gluten toxicity could be one of the most powerful triggering factors for developing epilepsy in CD. Learning disorders such as attention deficit hyperactivity disorder, short duration headaches, mild optic neuritis, encephalopathy, and DS could also be the initial neurological manifestations of atypical CD. A gluten-restricted diet may improve neurological complaints, epileptic discharges, and neuropsychiatric symptoms. All we found may be a small part of the full range of neurological disorders of unknown origin related to CD. Clinical suspicion should be the rule for accurate diagnosis of the disease.

Abstract
Celiac disease (CD) is a common and well defined autoimmune disorder caused by gliadin and related proteins of wheat, rye, and barley. Epidemiologic studies confirmed that CD is highly associated with other autoimmune diseases and with Down syndrome (DS). The symptomatic form of CD in patients with DS is more frequent than asymptomatic forms. However, growth impairment, anemia, intermittent diarrhea, and constipation are symptoms and signs typically of children with DS without CD. Late identification of the disease can lead to various complications, sometimes even very severe. Therefore, systematic screening for CD is essential in the management of children and adolescents with DS. Many medical organizations recommend screening in this group of patients. However, current policy statements vary in their recommendations for screening and there is still a need for establishing uniform diagnostic criteria.

Aims/Hypothesis: We sought to establish whether the increased incidence of diabetes associated with Down syndrome was due to a congenital deficit in β cells. Methods: The pancreas was obtained at autopsy from nondiabetic subjects with Down syndrome (n = 29) and age-matched nondiabetic control subjects without Down syndrome (n = 28). The pancreas sections were evaluated for the fractional β-cell area. Results: No difference was found in the fractional β-cell area between the subjects with Down syndrome and the control subjects. Conclusions/Interpretations: The increased incidence and prevalence of diabetes in individuals with Down syndrome is not due to an underlying congenital deficiency of β cells.

Abstract
Introduction The results of studies assessing whether patients with Down syndrome have increased risk of coeliac disease are contradictory. The prevalence of coeliac disease in patients with Down syndrome is estimated at a wide range between 1% to as much as 18.6%. Aim To assess coeliac disease prevalence in patients with Down syndrome in Poland. Material and methods The study enrolled 301 patients with Down syndrome from six centres in Poland (Wroclaw, Sandomierz, Rzeszow, Grudziadz, Katowice, and Bydgoszcz). We measured the concentration of anti-tissue transglutaminase IgA antibodies and anti-deamidated gliadin peptide IgG antibodies in all patients. Patients with abnormal positive (> 10 U/ml) or inconclusive (7–10 U/ml) result of the serological test were offered endoscopic biopsy of the small intestine in the main centre. Results In 31 (10.3%) patients increased concentrations of the investigated antibodies were found, including 19 (6.3%) patients with increased tTg-IgA concentration, 27 (8.97%) patients with increased concentration of DGP-IgG, and 15 (4.98%) patients with increased concentration of both types of antibodies. Endoscopic biopsy of the small intestine was planned for all 31 patients with abnormal results of at least one antibody test and for 2 patients with inconclusive results. One of them suffered from previously diagnosed and histologically confirmed coeliac disease. Biopsy was not conducted in 9 patients due to contraindications, lack of their consent, or introduction of a gluten-free diet by the parents before the examination. In a group of 23 patients who underwent endoscopic biopsy of the small intestine, in 15 patients the histopathological picture of the small intestinal mucosa was typical for coeliac disease, 2 patients were diagnosed with lesions of grade 1 according to the classification by Marsh-Oberhuber, 1 patient was diagnosed with focal shortening of villi and hypertrophy of the crypts with no intraepithelial lymphocytosis (remains under gastrological observation), 2 patients were diagnosed with mucosal inflammation of the duodenum, and 3 patients were found to have a normal histopathological picture of the small intestine. Analysis of the data included in the questionnaires of all patients showed no statistically significant differences in the body height, body mass index, prevalence of abdominal pain, diarrhoea, constipations, recurrent stomatitis, enamel hypoplasia, thyroid diseases, or hypertransaminasaemia between the groups of patients with normal and abnormal serological test results. Significantly higher prevalence of abdominal flatulence (p < 0.05) and epilepsy (p < 0.05) was found in the group of patients whose serological test results were negative. Conclusions Patients with Down syndrome are a high-risk group for coeliac disease in the Polish population, with an estimated prevalence of at least 5.4%. Serological tools based on tTG-IgA and DGP-IgG tests are useful for the diagnosis of coeliac disease in Down syndrome patients. tTG-IgA test may be superior to DGP-IgG test in patients with normal total IgA level. Tests for coeliac disease should be carried out in all Polish patients with Down syndrome, regardless of the clinical picture.

Abstract
Down syndrome (DS), caused by trisomy of chromosome 21, is associated with immunological dysfunctions such as increased frequency of infections and autoimmune diseases. Patients with DS share clinical features, such as autoimmune manifestations and specific autoantibodies, with patients affected by autoimmune polyendocrine syndrome type 1. Autoimmune polyendocrine syndrome type 1 is caused by mutations in the autoimmune regulator (AIRE) gene, located on chromosome 21, which regulates the expression of tissue-restricted Ags (TRAs) in thymic epithelial cells. We investigated the expression of AIRE and TRAs in DS and control thymic tissue using quantitative PCR. AIRE mRNA levels were elevated in thymic tissue from DS patients, and trends toward increased expression of the AIRE-controlled genes INSULIN and CHRNA1 were found. Immunohistochemical stainings showed altered cell composition and architecture of the thymic medulla in DS individuals with increased frequencies of AIRE-positive medullary epithelial cells and CD11c-positive dendritic cells as well as enlarged Hassall's corpuscles. In addition, we evaluated the proteomic profile of thymic exosomes in DS individuals and controls. DS exosomes carried a broader protein pool and also a larger pool of unique TRAs compared with control exosomes. In conclusion, the increased AIRE gene dose in DS could contribute to an autoimmune phenotype through multiple AIRE-mediated effects on homeostasis and function of thymic epithelial cells that affect thymic selection processes.

Abstract
The incidence of allergy and autoimmune disease in the US and other industrialized nations is increasing, and gluten-related disorders are no exception. The US has documented a profound rise in celiac disease that cannot be fully explained by improved serological techniques or better recognition by physicians. Non-celiac gluten sensitivity, a condition only recently recognized by the medical community, has become a commonly diagnosed entity. Proteins, including gluten are increasingly being identified as a source of wheat allergy. Although the gluten free diet represents a safe and effective treatment for these conditions, there is still much to be learned about the development of gluten-related disorders and the apparent increase in incidence within the US. In this article, we present a review of current knowledge on the epidemiology of gluten-related disorders within a global context, with a focus on diagnostic trends and the evaluation of potential risk factors.

Abstract
BACKGROUND Coeliac disease (CD), originally thought to be largely confined to Northern Europe and Australasia and uncommon in North America and the Middle East, is now recognised to be equally common in all these countries. It is still thought to be rare in the Orient and Sub-Saharan Africa. AIM To assess geographical differences and time trends in the frequency of CD. METHODS Medline and Embase searches were conducted on 10 November 2012, from 1946 and 1980 respectively, using the key words: coeliac disease or celiac disease + prevalence or incidence or frequency. RESULTS There were significant intra- and inter-country differences in the prevalence and incidence of CD. Only 24 ethnic Chinese and Japanese patients have been reported in the English literature. Of CD-associated HLA DQ antigens, DQ2 occurs in 5-10% of Chinese and sub-Saharan Africans, compared to 5-20% in Western Europe. DQ8 occurs in 5-10% of English, Tunisians and Iranians, but in <5% of Eastern Europeans, Americans and Asians. The prevalence and incidence of both clinically and serologically diagnosed CD increased in recent years. These geographical and temporal differences seem genuine, although variable indices of suspicion and availability of diagnostic facilities are confounding factors. CONCLUSIONS Coeliac disease is increasing in frequency, with significant geographical differences. Although few cases have been described to date in the Orient and Sub-Saharan Africa, there is a significant prevalence of HLA DQ2 and wheat consumption is of the same order as that in Western Europe. CD may therefore become more common in the future in these countries.

Abstract
OBJECTIVE To study the prevalence of celiac disease in Indian children with Down syndrome and evaluate its clinical and laboratory predictors. METHODS Prevalence of celiac disease (CD) was assessed in 100 patients with Down syndrome (DS) attending pediatric genetic clinic at All India Institute of Medical Sciences,in a prospective observational study, based on the characteristic symptomatology, positive indirect immunofluorescence anti endomyseal antibody(anti EMA) test and duodenal histology based on adapted Marsh criteria. Clinical and laboratory features were compared in children having both CD and DS and those with DS alone. RESULTS Anti EMA was positive in 7 out of 100 patients screened for CD; 6 in whom the duodenal biopsy could be done showed histopathological features consistent with celiac disease. Amongst various clinical features evaluated as possible risk factors; pallor reached statistical significance (OR = 7.04 95%CI 1.08-45.7). In addition anemia (Hb <11 g%) was significantly associated with CD (p = 0.06). CONCLUSIONS The present results showed a high prevalence of CD in DS children in a tertiary hospital in India and low hemoglobin to be an important risk factor. The authors recommend that all Indian children with Down syndrome, particularly those with anemia should be screened for celiac disease.

Abstract
Celiac disease results from the interplay of genetic, environmental, and immunologic factors. An understanding of the pathophysiology of celiac disease, in which the trigger (wheat, rye, and barley) is known, will undoubtedly reveal basic mechanisms that underlie other autoimmune diseases (eg, type 1 diabetes) that share many common pathogenic perturbations. This review describes seminal findings in each of the 3 domains of the pathogenesis of celiac disease, namely genetics, environmental triggers, and immune dysregulation, with a focus on newer areas of investigation such as non-HLA genetic variants, the intestinal microbiome, and the role of the innate immune system.

Abstract
Celiac disease (CD) is a gluten-sensitive enteropathy that develops in genetically susceptible individuals by exposure to cereal gluten proteins. This review integrates insights from immunological studies with results of recent genetic genome-wide association studies into a disease model. Genetic data, among others, suggest that viral infections are implicated and that natural killer effector pathways are important in the pathogenesis of CD, but most prominently these data converge with existing immunological findings that CD is primarily a T cell-mediated immune disorder in which CD4(+) T cells that recognize gluten peptides in the context of major histocompatibility class II molecules play a central role. Comparison of genetic pathways as well as genetic susceptibility loci between CD and other autoimmune and inflammatory disorders reveals that CD bears stronger resemblance to T cell-mediated organ-specific autoimmune than to inflammatory diseases. Finally, we present evidence suggesting that the high prevalence of CD in modern societies may be the by-product of past selection for increased immune responses to combat infections in populations in which agriculture and cereals were introduced early on in the post-Neolithic period.

Abstract
OBJECTIVE To describe the prevalence of Coeliac disease (CD) and its clinical management. METHODS Narrative review. RESULTS Coeliac disease (CD) is an immune-mediated disorder that primarily affects the gastrointestinal (GI) tract. Recent data suggest a prevalence of about 1% in most Western countries, a figure that likely represents an increase in the prevalence of CD. Risk groups include those who are members of families with individuals who have CD as well as those with Type I diabetes and a variety of autoimmune diseases. Whereas biopsy is the gold standard in diagnosis, serological tests are crucial in determining who should undergo endoscopy and biopsy. HLA testing should be used only to rule out CD. Currently, a gluten-free diet is the only available therapy. CONCLUSION In conclusion, CD is one of the most common immune-mediated disorders in the Western world. It should be considered in patients with a number of varying GI and non-GI symptoms, as well as in high-risk groups that include first-degree relatives.

Abstract
INTRODUCTION Celiac disease (CD) affects up to 1% of the general population. Studies from several countries reported higher prevalence rates in Down syndrome (DS) patients. The aim of this study was to determine the CD prevalence in Portuguese DS patients. PATIENTS AND METHODS The study cohort consisted of 98 DS patients (58 male and 40 female, 1-45 years). Serological screening was performed using immunoglobulin A (IgA) anti-endomysium antibody (EMA), determined by an immunofluorescence assay with monkey esophagus as substrate, and IgA anti-tissue transglutaminase (tTG), measured by an enzyme-linked immunosorbent assay with tissue transglutaminase as antigen. The serologically positive patients were selected for upper endoscopy with biopsy procedure. The intestinal mucosa biopsy specimens were classified according to the Marsh criteria. RESULTS Nineteen patients (19.4%), nine children and 10 adults, were positive for IgA EMA and 12 (12.2%), eight children and four adults, for IgA anti-tTG. All the IgA anti-tTG positive patients were simultaneously positive for IgA EMA. The histological findings (Marsh III) confirmed CD in nine of the remaining 17 patients who underwent endoscopy and biopsy - prevalence rate of 9.2%. All Marsh III patients were IgA EMA positive, but four Marsh III patients were IgA anti-tTG negative. CONCLUSION DS Portuguese patients have a high CD prevalence rate. This study supports that, in our population, the current recommendations for CD screening in DS patients should be implemented and screening must be EMA based.

Abstract
Down syndrome has a prevalence of one in 500 to one in 1,000 live births and is the most common cause of mental retardation. Most patients are treated in childhood and adolescence for mental or growth retardation. Studies that evaluate bone mass in Down syndrome are limited, and many are small case series in pediatric and adult populations who live either in the community or in residential institutions. Several environmental and hormonal factors contribute to low bone mineral density in such patients. Muscle hypotonia, low amounts of physical activity, poor calcium and vitamin D intakes, hypogonadism, growth retardation and thyroid dysfunction contribute to substantial impairments in skeletal maturation and bone-mass accrual that predispose these patients to fragility fractures. Here, we review indications and limitations of bone-mass measurements in children, summarize the endocrine and skeletal abnormalities in patients presenting with Down syndrome, and review studies that investigate therapeutic strategies for such patients.

Abstract
OBJECTIVES False-positive results of anti-tissue-transglutaminase (tTG) IgA autoantibodies have been reported in subjects with a genetic risk for celiac disease (CD). The aims of this retrospective study were to assess the prevalence of false-positive tTG titers in patients at risk of CD compared with symptomatic children and to evaluate the influence of age and indication for testing on tTG titers. PATIENTS AND METHODS All tTG results measured in our institution during a 33-month period were evaluated. Patients with known CD were excluded. Indications for testing were either symptoms suggestive of CD (group 1) or history of being at risk for CD (group 2). Duodenal biopsies were recommended if titers were positive (> or =10 U/mL) and offered if borderline (> or =4 to <10 U/mL). RESULTS The final analysis included 2056 patients, 1707 belonged to group 1, and 349 to group 2. All 65 patients with positive tTG results underwent biopsy (group 1: 57, group 2: 8). Celiac disease was confirmed in 61 subjects (median titer: 107.8 U/mL, range 12.0-1748 mL, NS between group 1 and 2), whereas 4 had normal histology (10.2-25.2 U/mL). Three out of 16 patients with borderline results underwent biopsy and had normal histology. Borderline titers were more common in group 2 patients (2.6% vs 0.4%, P<0.001). Multiple regression analysis in patients with negative tTG results (n=1975) revealed that titers were independently related to age (P<0.05) and indication for testing (P<0.001). CONCLUSIONS The influence of age and genetic predisposition/risk has to be taken into account when interpreting tTG results.

Abstract
OBJECTIVE To assess the effect of a prospective screening strategy for the early diagnosis of celiac disease (CD) in children with Down syndrome (DS). STUDY DESIGN Blood samples were taken from 155 children with DS. Buccal swabs were also taken from 9 of these children for determination of human leukocyte antigen (HLA)-DQ2 or HLA-DQ8 positivity. Independently, immunoglobulin A anti-endomysium-(EMA) and anti-tissue transglutaminase antibodies (TGA) were tested. An intestinal biopsy was performed to confirm the diagnosis of CD. RESULTS Sixty-three children (40.6%) had test results that were positive for HLA-DQ2 or HLA-DQ8. Results of HLA DQ-typing of DNA isolated from blood and buccal swabs were identical. Eight of the children in whom test results were positive for HLA-DQ2/8 also had positive test results for EMA and TGA. CD was confirmed in 7 of these children with an intestinal biopsy, and in 1 child, CD was suggested with improvement on a gluten-free diet. CONCLUSIONS We found a prevalence of CD in children with DS of 5.2% (10 times higher than the general Dutch population). We recommend HLA-DQ2/8 typing from buccal swabs in the first year of life and initiating serologic screening of children with DS in whom test results are positive for HLA-DQ2 or DQ8 at age 3 years. Early knowledge of negative HLA-DQ2/8 status can reassure most parents that their children do not have a CD risk.

Abstract
OBJECTIVES The human leukocyte antigen (HLA) system includes genes involved in graft-vs-host rejection and in immune response. The discovery that HLAs are associated with several diseases led to appealing developments both in basic biomedical research and in clinical medicine, and offered the opportunity to improve the understanding of pathogenesis and classification of diseases, as well as to provide diagnostic and prognostic indicators. The aim of this article is to review the association between HLA alleles and autoimmune digestive disease and its current relationship with modern HLA nomenclature and clinical practice. METHODS Articles dealing with the association between HLAs and autoimmune digestive disease (including celiac disease, inflammatory bowel disease, autoimmune hepatitis, sclerosing cholangitis and primary biliary cirrhosis) were searched for using Pubmed and SCOPUS databases from earliest records to January 2008. RESULTS The review has provided two sections. In the first, we explain the basic principles of HLA structure, function, and nomenclature, as an introduction to the second section, which describes current associations between HLA alleles and digestive diseases. The clinical implications of each HLA association are critically discussed. Actually, a clinical role for HLA typing is suggested for only a few conditions, e.g., celiac disease. CONCLUSIONS The knowledge of current HLA nomenclature and of its association with some digestive diseases such as celiac disease can be useful in clinical practice for diagnostic and prognostic purposes. This can avoid improper HLA typing as well as stressing the need for further studies on other possible clinical applications.

Abstract
BACKGROUND Celiac disease (CD) is overrepresented among patients with Down syndrome (DS), who frequently lack any typical symptoms. Therefore, screening for CD is recommended in this high-risk group. The aim of the study was to determine the prevalence of CD in Arab children with DS and evaluate the contribution of immunoglobulin (Ig) A and IgG anti-gliadin antibodies (AGA), IgA and IgG tissue transglutaminase (TTG) antibodies, and IgA anti-endomysial antibodies (EMA) to screen for CD in children with DS. PATIENTS AND METHODS A total of 52 Arab patients with DS and 52 healthy Arab control subjects were studied for CD using various serological markers. Data on age, sex, weight, height, gastrointestinal symptoms, and endocrine abnormalities were recorded. Human leukocyte antigen (HLA) was studied in patients undergoing small intestinal biopsy. RESULTS Five patients with DS were IgA TTG-positive and only 1 patient with DS was IgG TTG-positive. EMA was negative in all patients with DS. TTG (IgA and IgG) and EMA were negative in all control children. IgA AGA was positive in 12 patients with DS and 3 control subjects (P = 0.02), whereas IgG AGA was positive in 41 patients with DS and 26 control subjects (P = 0.004). Only children testing positive for TTG underwent upper endoscopy with duodenal biopsy. Two children with DS were diagnosed with CD. Both patients were IgA TTG-positive. One was HLA DQ2-positive and another was negative for HLA DQ2 and DQ8. CONCLUSIONS CD is prevalent (3.8%) in Arab patients with DS. Based on our cohort, IgA TTG is useful in diagnosing patients with CD and DS.

Abstract
There is an unexplained excess of type 1 diabetes and other organ-specific autoimmune diseases in children with Down's syndrome, but the immunogenetic characteristics of diabetes in Down's syndrome have not been investigated. We studied the frequency of islet autoantibodies in 106 children with Down's syndrome and no history of autoimmunity and analyzed HLA class II genotypes in 222 children with Down's syndrome, 40 children with Down's syndrome and type 1 diabetes, 120 age- and sex-matched children with type 1 diabetes, and 621 healthy control subjects. Co-occurrence of at least two islet autoantibody markers was observed in 6 of 106 nondiabetic children with Down's syndrome compared with 13 of 2,860 healthy age-matched children (P < 0.001). There was an excess of diabetes-associated HLA class II genotypes in children with Down's syndrome and type 1 diabetes compared with age- and sex-matched healthy control subjects (P < 0.001). Down's syndrome children with type 1 diabetes were, however, less likely to carry the highest risk genotype DR4-DQ8/DR3-DQ2 than children with type 1 diabetes from the general population (P = 0.01) but more likely to carry low-risk genotypes (P < 0.0001). The frequency of subclinical islet autoimmunity is increased in Down's syndrome, and susceptibility to type 1 diabetes in Down's syndrome is partially HLA mediated. Other factors, possibly including genes on chromosome 21, may increase the penetrance of type 1 diabetes in Down's syndrome.

Abstract
BACKGROUND Studies demonstrate an increased prevalence of celiac disease in persons with Down syndrome, leading some organizations and authors to recommend universal screening of children with Down syndrome. However, many children with Down syndrome are asymptomatic, and the long-term implications of screening are unknown. The complication of celiac disease that leads to mortality in the general population is non-Hodgkin's lymphomas. OBJECTIVES The purpose of this research in asymptomatic children with Down syndrome was to (1) calculate the number needed to screen to prevent a single case of lymphoma and (2) present a cost-effectiveness study of screening. METHODS We constructed a decision tree using probabilities derived from the published literature for Down syndrome or from the general population where Down syndrome-specific data were not available. Celiac disease was determined by serologic screening and confirmation with intestinal biopsy. Sensitivity analysis was used to alter probability estimates affecting the cost of preventing lymphoma. RESULTS Using our baseline values, the no-screen strategy is dominant; that is, screening not only costs more but also results in fewer quality-adjusted life-years. A screening strategy costs more than $500,000 per life-year gained. Screening all asymptomatic children with Down syndrome for celiac disease costs almost $5 million to prevent a single case of lymphoma. CONCLUSION These analyses do not support the cost-effectiveness of screening, and more data are needed before recommendations to screen asymptomatic children with Down syndrome for celiac disease can be made.

METHODS Single nucleotide polymorphisms of TNFalpha (-308G-->A promoter region), IFNgamma (+874T-->A promoter region) and IL-10 (-1082G-->A promoter region) have been studied in 10 Down patients with coeliac disease, in 40 Down patients without coeliac disease and in 220 healthy controls. Clinical features were also studied in coeliac disease-Down syndrome patients. RESULTS The 10 coeliac disease-Down syndrome patients had a biopsy proven coeliac disease afterward a serological testing positive to antigliadin, antiendomysium and antitransglutaminase antibodies. Intestinal biopsy showed total atrophy in 6/10 and partial villous atrophy in 4/10 of them. All coeliac disease-Down syndrome patients had silent forms of coeliac disease and classical trisomy 21. No significant differences were observed for the IFNgamma and IL-10 polymorphisms in the studied groups. A significant trend for increase of TNFalpha -308A positive frequency was observed in coeliac disease-Down syndrome patients compared to healthy controls (p=0.043). CONCLUSIONS Single nucleotide polymorphisms of IFNgamma and IL-10 do not play a role in predisposing Down syndrome patients to coeliac disease, while the TNFalpha -308 allele could be an additional genetic risk factor for coeliac disease in trisomy 21.

Abstract
To address the issue of screening children for celiac disease, current evidence has been summarized and placed within the context of 8 established criteria for childhood screening. Screening all children for celiac disease is not recommended at this time. Areas with gaps in knowledge are identified as areas in need of further study. These include the timing of screening, defining the natural history of screening-identified celiac disease, developing tools to predict disease onset and disease remission, and the risks of screening.

Abstract
OBJECTIVES We measured circulating autoantibodies and evaluated the potential of circulating antitissue transglutaminase (tTG) antibodies to determine the presence of celiac disease (CD) in children with Down syndrome. METHODS An ELISA based on recombinant human tTG was used to measure the levels of immunoglobulin A and immunoglobulin G antibodies in serum samples from 72 children with Down syndrome, 52 children with biopsy-verified CD, 21 disease controls with a normal small intestinal mucosa and 23 healthy controls. Of the 72 Down syndrome children, 11 under-went a small intestinal biopsy. RESULTS Four of 72 children with Down syndrome were diagnosed as having CD and three of them had serum levels of immunoglobulin A tTG antibodies greater than 6 U/mL (668, 147 and 7 U/mL). One Down syndrome child with biopsyproven CD had normal levels of immunoglobulin A tTG. Two Down syndrome children had increased levels of immunoglobulin A tTG (13 and 7 U/mL) but none of these children had an intestinal biopsy performed. Of the 52 CD subjects (median 664 U/mL) one was negative for immunoglobulin A tTG (5 U/mL) and all healthy controls (median 1.2 U/mL) and disease controls (median 0.9 U/mL) had immunoglobulin A tTG antibody levels less than 6 U/mL. Two of four Down syndrome children with CD and 36 of 52 celiac children had increased serum levels of immunoglobulin G tTG antibodies. There was no correlation between the serum levels of tTG and antithyroid autoantibodies. CONCLUSIONS Although the diagnosis of CD depends on histologic evaluation of intestinal biopsies, detection of anti-tTG antibodies provides a useful complementary diagnostic method for CD in children with Down syndrome.

Abstract
BACKGROUND Celiac disease, also known as gluten-sensitive enteropathy, is a chronic inflammation disease of the small intestinal mucosa. Detection of Ig-A antigliadin antibodies (AGA) and antiendomysial antibodies (EMA) in serum is important in the diagnosis and screening for celiac disease. Antiendomysial antibodies have greater sensitivity compared to antigliadin antibodies. It has been reported that the prevalence of celiac disease is higher in children with Down syndrome than the other autoimmune conditions. The aim of the present study was to investigate the incidence of celiac disease in children with Down syndrome, to assess the availability of Ig-A AGA and EMA for serologic screening, and to highlight the importance of follow-up for children with Down syndrome. METHODS Forty-seven children with Down syndrome without known celiac disease were tested for total blood count, thyroid function tests, immunoglobulin values, Ig-A AGA and EMA. Duodenal biopsy was performed on eight patients who showed at least one serologically positive marker. RESULTS The ages of the children with Down syndrome ranged from 2 to 18 years (30 boys/17 girls). The mean age was 6.55 +/- 3.88. Total blood count and immunoglobulin values were normal. Eleven of the 47 patients (23.40%) were found to be serologically positive, 10 (21.28%) having antigliadin antibody concentrations above normal; and six (12.77%) being positive for antiendomysial antibody. In five patients (10.64%), both Ig-A AGA and EMA concentrations were high and positive. Duodenal biopsies of three of eight cases (37.50%) revealed villous atrophy, lymphocyte infiltration and crypt hyperplasia. Three cases with abnormal biopsy results (100%) were below the 10th percentile for weight and height. Hypo-thyroidism was detected in one of 11 cases where at least one serologic marker was positive. CONCLUSION Children with Down syndrome should be carefully examined in their follow up, and celiac disease should be considered in cases with growth retardation. Ig-A antigliadin antibodies and EMA are non-invasive, cheap and readily available serologic screening tests for celiac disease, and the positivity of both markers gives the most reliable result.

Abstract
BACKGROUND Growth in children with Down's syndrome (DS) differs markedly from that of normal children. The use of DS specific growth charts is important for diagnosis of associated diseases, such as coeliac disease and hypothyroidism, which may further impair growth. AIMS To present Swedish DS specific growth charts. METHODS The growth charts are based on a combination of longitudinal and cross sectional data from 4832 examinations of 354 individuals with DS (203 males, 151 females), born in 1970-97. RESULTS Mean birth length was 48 cm in both sexes. Final height, 161.5 cm for males and 147.5 cm for females, was reached at relatively young ages, 16 and 15 years, respectively. Mean birth weight was 3.0 kg for boys and 2.9 kg for girls. A body mass index (BMI) >25 kg/m(2) at 18 years of age was observed in 31% of the males and 36% of the females. Head growth was impaired, resulting in a SDS for head circumference of -0.5 (Swedish standard) at birth decreasing to -2.0 at 4 years of age. CONCLUSION Despite growth retardation the difference in height between the sexes is the same as that found in healthy individuals. Even though puberty appears somewhat early, the charts show that DS individuals have a decreased pubertal growth rate. Our growth charts show that European boys with DS are taller than corresponding American boys, whereas European girls with DS, although being lighter, have similar height to corresponding American girls.

Abstract
BACKGROUND The increased incidence of coeliac disease in patients with Down syndrome makes screening of coeliac disease in this population advisable. AIM Evaluation of efficiency of different serological markers to detect coeliac disease in Down syndrome patients. PATIENTS A total of 56 Down syndrome patients (aged: 1-17 years) were included in study. METHODS Patients were evaluated for both IgG and IgA anti-transglutaminase antibodies and for anti-gliadin IgA and IgG antibodies using either purified omega-gliadin, wheat ethanol extract or commercial gliadin. Patients who had at least one positive result were evaluated for antiendomysium antibodies using either monkey oesophagus or human umbilical cord by indirect immunofluorescence. Coeliac disease was diagnosed by typical histological changes on duodenal mucosa. RESULTS Increased levels of at least one anti-gliadin IgA and IgG antibody marker were found in 27 out of 56 cases (26 for IgG and 9 for IgA). 11/56 were positive for IgG anti-transglutaminase antibodies and two of them were also positive for IgA anti-transglutaminase antibodies and anti-endomysium antibodies. These two patients were finally diagnosed as coeliacs. Gliadin antigenic fractions employed produced differences in the performance of the anti-gliadin IgA and IgG antibody test. The use of commercial gliadin or wheat ethanol extract showed low sensitivity in IgA anti-gliadin IgA and IgG antibody determination, whereas good sensitivity and specificity were observed with omega-gliadins. IgG anti-transglutaminase antibodies showed a high proportion of false positive results (9 out of 56), whereas anti-endomysium antibodies and IgA anti-transglutaminase antibodies presented an excellent correlation with presence of active coeliac disease. CONCLUSIONS Two out of 56 Down syndrome patients were diagnosed as coeliacs, corresponding to an incidence of 3.6%. The use of omega-gliadin presented the best efficiency in anti-gliadin IgA and IgG antibody determination whereas IgA anti-transglutaminase antibodies and anti-endomysium antibody determination showed an absolute correlation with presence of active coeliac disease.

Abstract
Coeliac disease is a chronic disease caused by a permanent intolerance to ingested gluten resulting in immunologically mediated inflammatory damage of the small-intestinal mucosa. The wide spectrum of clinical symptoms is partly due to the malnourished state caused by the malabsorption of macro- and micronutrients. Fertility problems, sexual dysfunction and obstetrical complications are more frequently observed in patients with coeliac disease. These reproductive disorders may be a consequence of the endocrine derangements caused by selective nutrient deficiencies. Nowadays, the early diagnosis and treatment of coeliac disease is possible and not very costly. Therefore, coeliac disease must be seriously considered in the preconceptional screening and treatment of patients with reproductive disorders.

Abstract
OBJECTIVE During the past decade, it has been shown that the association between Down's syndrome and coeliac disease is relatively frequent Prevalence rates of coeliac disease in patients with Down's syndrome reported by different authors are significantly higher than those found in the general population. The main purpose of this study was to assess the prevalence of coeliac disease in a series of subjects with Down's syndrome from our geographical area. DESIGN A cross-sectional study. SETTING Outpatient paediatric clinics of acute-care teaching hospitals in Barcelona, Spain. PARTICIPANTS A total of 284 persons with Down's syndrome aged between 1 and 25 years were included in the study. In all cases, serum concentrations of antigliadin antibodies (AGAs) (Pharmacia CAP system enzyme-linked immunosorbent assay), antiendomysium antibodies (AEA) (indirect immunofluorescence) of immunoglobulin (Ig)A class or IgG class in cases of IgA deficiency were determined. Jejunal biopsy was offered to all patients with AEA positivity and to those with suggestive clinical manifestations of coeliac disease. In all patients, a clinical study was made to evaluate the presence and time-course of symptoms related to coeliac disease. MAIN OUTCOME MEASURES AND RESULTS In 18 of the 284 subjects with Down's syndrome, aged between 2 and 15 years, coeliac disease was confirmed by jejunal biopsy. Accordingly, the minimum prevalence rate of coeliac disease was of 6.3%. Ninety-four percent (17/18) and 78% (14/18) of patients with the association Down's syndrome and coeliac disease showed AEA and AGA positivity, respectively. Fifteen patients with the association coeliac disease and Down's syndrome (15/18) showed clinical manifestations compatible with coeliac disease, with a predominance of intestinal symptoms (8/18) over those with atypical or extra-intestinal forms (7/18). Three patients had clinically silent forms of coeliac disease (3/ 18). CONCLUSIONS Measurement of serum concentrations of AEA should be added to the list of screening tests for coeliac disease in patients with Down's syndrome, otherwise definite association between both diseases may pass unnoticed and diagnosis of coeliac disease be considerably delayed.

Abstract
OBJECTIVES To investigate the best approach to screen for celiac disease (CD) in patients with Down syndrome (DS). STUDY DESIGN One hundred thirty-seven children with DS were followed up longitudinally. CD screening was offered in 1994, 1996, and 1999 by determination of serum immunoglobulin A-anti-endomysium antibodies (AEA). The HLA-DQA1*0501/DQB1*02 allelic combination known to be strongly positively associated with CD was typed. All IgA-AEA-positive children were given the opportunity to undergo a small bowel biopsy: if villous atrophy was found, the diagnosis of CD was established. RESULTS CD was diagnosed in 11 (8%) children: 8 in 1994 and 3 in 1996. All of them carried the HLA-DQ alleles associated with CD. The presence of symptoms was not useful in discriminating which children could have CD. CONCLUSIONS Screening once in a lifetime is not enough to detect CD in patients with DS. We propose a new, accurate, and cost-sparing 2-step strategy for screening, based on selection of the individuals with potential CD by HLA-DQ typing and on longitudinal serologic CD screening in this selected group.

Abstract
According to recent reports in the literature, there seems to be an association between alopecia areata and celiac disease. The present author describes a 9-year-old girl with Down's syndrome, and alopecia areata, and documented celiac disease, who displayed a normal growth of hair after a gluten-free diet. Given the high prevalence of these two diseases in patients with Down's syndrome, the present author recommends both serological screening for celiac disease in every individual with Down's syndrome, and in particular, the inclusion of such screening in any diagnostic work-up for alopecia areata.

Abstract
BACKGROUND Numerous studies in Europe have documented a high prevalence of celiac disease in Down syndrome. This study was undertaken to estimate the prevalence of celiac disease in Down syndrome in the southeastern United States. METHODS Seventy-five patients with Down syndrome were screened using immunoglobulin (Ig)A-anti antiendomysium antibodies, IgA-antigliadin antibodies, and total IgA level. When either antiendomysium or antigliadin antibodies produced positive findings, patients were referred to a pediatric gastroenterologist for consideration of a duodenal biopsy. RESULTS Thirteen percent (10/75) were positive for antiendomysium antibodies. Half of these patients were also positive for antigliadin antibodies. Six of 10 patients positive for antiendomysium antibodies underwent intestinal biopsy. Changes consistent with celiac disease were documented in five. Histologic findings ranged from focal to total villous atrophy. None had IgA deficiency. CONCLUSIONS There was a high prevalence of positivity to antiendomysium antibody in Down syndrome. Antiendomysium antibody was a more sensitive screening test than antigliadin antibody. The prevalence of celiac disease in Down syndrome in the southeastern United States was 1 in 14 cases. Screening with antiendomysium antibody and IgA for all children with Down syndrome is recommended, even if there are no gastrointestinal symptoms.

Abstract
BACKGROUND An association between Down syndrome and celiac disease has been reported. This study was conducted to determine the association between childhood celiac disease and Down syndrome in the county of Uppsala, Sweden. METHODS All 76 children with Down syndrome (1-18 years) were screened for the occurrence of anti-gliadin antibodies (AGA) and anti-endomysium antibodies (EMA). Twelve children with suspected celiac disease were investigated further. RESULTS Increased levels of both IgA and IgG AGA were found in 26% of the children and of EMA in and 5 of 76. Celiac disease was diagnosed in at least three of the children (3.9%; 95% confidence interval 0%-8.3%), and it could have been present in as many as eight. Three of the five EMA-positive children with suspected celiac disease had the HLA phenotype DR3, DQ2. CONCLUSIONS The results show that determination of EMA is more useful as a screening test for celiac disease and for follow-up than is AGA in children with Down syndrome. The present study also confirms that celiac disease is overrepresented among Swedish children with Down syndrome and that celiac disease should be considered in all persons with Down syndrome.

Abstract
Down syndrome (trisomy 21) has many manifestations that affect multiple organ systems, and we describe the wide array of imaging findings. Common cardiovascular and gastrointestinal entities are congenital heart disease (atrioventricular canal), bowel atresias (duodenal and anal), and Hirschsprungs disease. Children with Down syndrome have an 18-20 fold increased incidence of leukemia. Pulmonary hypoplasia, lung cysts, and pig bronchus (origin of the right upper lobe bronchus from the trachea) have been described. Neurologic findings include mineralizing vasculopathy of the basal ganglia, Moyamoya disease, and cerebellar/vermian hypoplasia. Musculoskeletal manifestations are numerous and include eleven ribs, hypersegmented sternum, abnormal pelvis, joint laxity/dislocations, and DDH (developmental dysplasia of the hip). Of special importance is the "triple jeopardy" of the upper cervical spine (atlanoaxial subluxation, hypoplastic posterior arch of C1, and atlantooccipital instability) and the resulting controversial cervical spine radiographic screening of children with Down syndrome. Knowledge of the many anomalies associated with Down syndrome can aid the clinician, not only in diagnosing abnormalities in these patients, but also in counseling families for potential problems that can occur in these children.

Abstract
OBJECTIVE To prospectively evaluate and compare the sensitivity, specificity, and positive and negative predictive values of serum antigliadin (AGA) and antiendomysium antibodies (EMA) in predicting the initial diagnosis of celiac disease. DESIGN Sera were tested prospectively for IgA and IgG AGA by enzymed-linked immunosorbent assay and IgA EMA by immunofluorescence techniques on monkey esophagus and human umbilical cord sections in 95 pediatric patients referred for duodenal biopsies. PATIENTS Ninety-five pediatric patients were referred for duodenal biopsies, with a clinical suspicion of celiac disease; 24 of those patients had celiac disease by criteria of the European Society for Pediatric Gastroenterology and Nutrition. SETTING A pediatric gastroenterology clinic of a tertiary care pediatric university hospital. RESULTS EMA testing on human umbilical cords was the most specific but was also the least sensitive. All the patients with biopsy-proven celiac disease were identified by either one or both serologic tests (100% combined sensitivity). The combination of AGA and EMA on monkey esophagus resulted in a negative predictive value of 100% accuracy. CONCLUSIONS A combination of AGA and EMA tests resulted in 100% sensitivity and 100% negative predictive value, useful in selecting patients for duodenal biopsy.
