Abstract
OBJECTIVES In young childhood, intestinal intussusception (IS) is the most common cause of small bowel obstruction. A lead point such as Meckel diverticulum, polyps, tumors, enlarged lymph nodes, cystic fibrosis, and Schoenlein-Henoch purpura are recognized causes. Association between celiac disease (CD) and IS has been well recognized in adults but rarely in children. Data on causes and outcome of intussusception among Saudi children are lacking in the literature. Our objectives were to characterize the pattern of IS among Saudi children and investigate the frequency, clinical presentation, and outcome of intussusception among children with CD. METHODS We searched the hospital's picture archiving and communications system for abdominal imaging studies (ultrasound, magnetic resonance imaging, computed tomography scan, and barium contrast studies), performed between 2008 and 2019, using "intussusception" as a search key word. The hospital medical records of the identified cases of intussusception (aged 0-14 years) were then retrospectively reviewed to collect demographic, clinical, laboratory and imaging findings, management, and outcome. RESULTS During the study period, 57 cases were identified as confirmed IS (31 boys, median age 1.95 years, range 0.33-11 years). Abdominal ultrasound was the diagnostic imaging study in 93%. An underlying cause (secondary IS) could be identified in 19 (33.3%) cases: CD in 6, malignancy and Henoch-Schoenlein purpura, 5 each, and Meckel diverticulum in 3; the remaining 38 (66.6%) cases of IS were idiopathic (primary IS). The presence of hypoalbuminemia and abdominal distension were significantly associated with secondary IS as compared with primary IS ( P < 0.001, P = 0.006, respectively). All of the 6 cases of IS associated with CD resolved spontaneously, but 3 were recurrent. CONCLUSIONS Secondary causes contributed to a large proportion of IS in our study cohort (33%) as compared with 5% to 10% in the literature. Celiac disease is an underrecognized cause of IS among children. A child with IS and hypoalbuminemia, anemia, or chronic diarrhea needs to be investigated for CD to avoid unnecessary surgery.

Abstract
OBJECTIVES Micronutrient deficiencies characterize classical "late-diagnosed" celiac disease (CeD). This study aimed to identify the prevalence of micronutrient deficiencies among children with "early-diagnosed" screening-identified CeD to determine the clinical value of routine testing for deficiencies in those patients. METHODS A case-control study was conducted on screening-identified CeD patients diagnosed during a mass screening study (84 patients, mean age 11.3 ± 2.6 years). The controls (443 children, mean age 10.8 ± 2.5 years) were negative for celiac disease serological screening. Hemoglobin, serum levels of iron, ferritin, folate, vitamin B12, vitamin A, vitamin E, 25-OH vitamin D, zinc, and selenium were measured. RESULTS The mean serum levels of hemoglobin, iron, ferritin, vitamin D, zinc, copper, and selenium were significantly lower in CeD patients than in healthy controls (hemoglobin 12.56 vs. 13.02 g/dL [p = 0.04]; iron 10.61 vs. 17.6 µmol/L [p < 0.001], ferritin 25.7 vs. 48.3 µg/L [p < 0.001], vitamin D 29.1 vs. 37.5 nmol/L, zinc 11.9 vs. 21.7 µmol/L, copper 18.9 vs. 32.5 µmol/L, selenium 1.04 vs. 1.36 µmol/L; p < 0.001). Patients with celiac and severe intestinal damage (Marsh IIIb and IIIc) had significantly lower serum ferritin and vitamin A levels than patients with mild intestinal damage (Marsh II and IIIa) (ferritin 15 vs. 22 µg/L, p < 0.025; vitamin A 0.85 vs. 1.35 µmol/L, p = 0.007). CONCLUSION Micronutrient deficiencies are still detectable in "early-diagnosed" screening-identified CeD cases, a clinically relevant result that strongly supports efforts for screening and early diagnosis of CeD.

Abstract
BACKGROUND There is some evidence of a higher prevalence of coeliac disease (CD) among patients with SLE than in the general population. However, the prevalence estimates vary substantially. OBJECTIVE To investigate the prevalence of CD among patients with SLE through systematic review and meta-analysis. METHODS We performed searches in the databases of Medline, Embase, Cochrane and Web of Science Core Collection between 1 January 1990 and 9 July 2023. A total of 2053 publications were rendered in the searches, of which 68 were reviewed in full text and 14 included in the analyses. Primary analysis estimated the pooled prevalence of biopsy-verified CD in patients with SLE. In the secondary analysis, the prevalence of serological markers indicative of CD was investigated. The quality of studies was appraised using the Joanna Briggs Institute Critical Appraisal Tool. We conducted meta-regression analyses to investigate associations between the prevalence of CD in individuals with SLE and publication year, study population size, CD prevalence in the general population, proportion of females and quality assessment score. RESULTS A total of 14 studies met the inclusion criteria, of which 11 were included in the primary analysis of biopsy-verified CD. Among 1238 patients with SLE, 14 had CD. The weighted pooled prevalence of CD was 0.7% (95% CI 0.0 to 1.8). The weighted pooled prevalence of CD serological markers in 1063 patients with SLE was 3.7% (95% CI 1.4 to 6.7). In meta-regression analyses, no associations between CD prevalence and study characteristics, demographics and quality assessment scores were found. CONCLUSIONS In this meta-analysis, we found a weighted pooled prevalence of biopsy-verified CD in patients with SLE comparable with the prevalence in the general population. Our findings do not support routine screening for CD in patients with SLE. However, individual screening could be considered in cases of clinical suspicion and additional risk factors for CD.

Abstract
BACKGROUND AND STUDY AIM Fungi have a well-established role in medicine. Herein, we describe the fungal profile and abundance in the gut of healthy Saudi children. PATIENTS AND METHODS Fecal samples from a random sample of 20 school-age Saudi children were collected, stored at -80 °C, and dispatched to the laboratory in the USA where fungal DNAs were isolated and shotgun metagenomic sequencing was performed. Abundance was presented as average percentage of fungal taxa. RESULTS The median age of the participants was 12.5 years (range: 7-16 years), and 35 % were male. Ascomycota were the most abundant phyla and Eurotiomycetes, Saccharomycetes, were the most abundant class. The average abundance of fungal genera were Histoplasma (36 %) and Saccharomyces (31 %). The most abundant species were Histoplasma capsulatum (36 %) and Saccharomyces pastorianus (23 %). Other less abundant but may be functionally important genera and species included Candida (2.6 %) and Saccharomycescerevisiae (8 %). CONCLUSION The profile and abundance of the gut fungi in healthy Saudi children reveals important differences compared to Western literature. Accordingly, this report represents a more appropriate reference than Western data to use as controls for regional studies aiming to identify fungi associated with disease.

Abstract
Background Celiac disease (CD) is an immune-mediated enteropathy that has been associated with other immune-related gastrointestinal disorders, such as eosinophilic esophagitis (EoE) and lymphocytic gastritis (LG). To our knowledge, this is the first study in Saudi Arabia that has described such an association. Aim To evaluate the prevalence of EoE and LG in children and adolescents with CD. Methods This was a retrospective cross-sectional study of all pediatric patients (aged 0-18 years) with CD following up at King Abdulaziz University Hospital, between January, 2014, and December, 2021. The study examined clinical, demographic, endoscopic, and histopathological data. Results Seventy-five patients with CD were included in the analysis. The median age was 12 years (range, 2-18 years). Male constituted 54.7% of the overall cohort (n = 41). The most common clinical symptoms were short stature (54.7%), weight loss (34.7%), abdominal pain (33.3%), abdominal distension (29.3%), anorexia (29.3%), diarrhea (24%), and vomiting (21.3%). The esophageal biopsy results reported were basal cell hyperplasia in 24 patients (32.9%), esophageal eosinophilia in 23 patients (31.5%), and EoE in 3 patients (4.1%). The gastric biopsy results were normal in 40 patients (53.3%). The most common abnormality was chronic inactive gastritis with no Helicobacter pylori (HP) infection (16%). LG was found in 3 patients (4%). Conclusions The prevalence of EoE in this cohort of patients with CD was lower than the prevalence recorded in a number of other studies. Further studies are needed to determine the effects of a gluten-free diet (GFD) on EOE and LG.

Abstract
Background: Celiac disease (CD) is a multifactorial, immune-mediated enteropathic disorder that may occur at any age with heterogeneous clinical presentation. In the last years, unusual manifestations have become very frequent, and currently, it is not so uncommon to diagnose CD in subjects with overweight or obesity, especially in adults; however, little is known in the pediatric population. This systematic review aims to evaluate the literature regarding the association between CD and overweight/obesity in school-age children. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. An electronic database search of articles published in the last 20 years in English was carried out in Web of Sciences, PubMed, and Medline. The quality of the included studies was assessed by using the STrengthening the Reporting of OBservational studies in Epidemiology statement. Results: Of the 1396 articles identified, 9 articles, investigating overweight/obesity in children/adolescents affected by CD or screening CD in children/adolescents with overweight/obesity, met the inclusion criteria. Overall, the results showed that the prevalence of overweight or obesity in school-age children (6-17 years) affected by CD ranged between 3.5% and 20%, highlighting that the coexistence of CD with overweight/obesity in children is not uncommon as previously thought. Conclusion: Although CD has been historically correlated with being underweight due to malabsorption, it should be evaluated also in children with overweight and obesity, especially those who have a familiar predisposition to other autoimmune diseases and/or manifest unusual symptoms of CD.

Abstract
PURPOSE OF REVIEW As incidence and prevalence of celiac disease is increasing, subclinical and asymptomatic presentations are more commonly identified through celiac disease screening. However, the United States Preventive Services Task Force released a statement in 2017 maintaining that there is insufficient evidence to recommend general population screening for celiac disease for asymptomatic individuals. This review summarizes the current available evidence on celiac disease screening. RECENT FINDINGS Literature demonstrates that by limiting screening to individuals with recognized symptoms, celiac disease diagnosis is frequently delayed or missed entirely. Most individuals with screening-identified celiac disease have previously unrecognized symptoms that improve through treatment with a gluten-free diet. Screening-identified individuals also demonstrate signs of impaired nutrition, growth, bone health, and quality of life which improve with treatment. Overall, celiac disease screening is viewed favorably by those identified through celiac disease screening programs. SUMMARY Individuals with screening-identified celiac disease may still incur complications from untreated disease and receive benefit from treatment with a gluten-free diet. More data is needed to determine the cost effectiveness of different mass screening approaches that incorporate the societal perspective towards screening.

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

Frequency and predictive factors for spontaneous normalization of anti-tissue transglutaminase-IgA serology among Saudi children with type 1 diabetes mellitus: A cohort study. Saudi J Gastroenterol 2023; 29:278-285.

Abstract
Background Celiac serology can be transiently elevated in patients with type 1 diabetes mellitus (T1DM) and normalized despite gluten consumption. This study aimed to identify the frequency and predictive factors of spontaneous normalization of anti-tissue transglutaminase (anti-TTG-IgA) antibodies in these patients. Methods The charts of all patients (≤18 years) with T1DM were retrospectively reviewed from 2012 to 2021 at a tertiary care center in Riyadh, Saudi Arabia. The following data were collected: clinical characteristics of the participants, anti-TTG-IgA-immunoglobulin (Ig) A antibody, and histological findings. The outcome of positive anti-TTG-IgA-IgA in patients with T1DM and the predictive factors for spontaneous normalization were investigated. Results Of the 1,006 patients with T1DM, 138 (13.7%) had elevated anti-TTG-IgA antibodies, celiac disease was diagnosed in 58/138 (42%) patients, spontaneous normalization of anti-TTG-IgA was observed in 65 (47.1%) patients, and fluctuating anti-TTG-IgA antibodies were seen in 15 (10.9%) patients. The patients with anti-TTG-IgA levels at 3-10 times the upper normal limits (UNL), and those with levels ≥10 times UNL were less likely to have spontaneous normalization of anti-TTG-IgA compared to patients with levels at 1-3 times UNL (hazard ratio [HR] = 0.28, 95% confidence interval [Cl] = 0.13-0.61, P = 0.001, and HR = 0.03, 95% Cl = 0.00-0.19, P < 0.001, respectively). Conclusion Asymptomatic patients with T1DM with mild elevation of anti-TTG-IgA need not be rushed for invasive endoscopy or exposed to an un-needed gluten-free diet but should rather have a regular follow-up of their celiac serology.

Front Pediatr 2023; 11:1197612. [PMID: 37534197 PMCID: PMC10391541 DOI: 10.3389/fped.2023.1197612] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 06/27/2023] [Indexed: 08/04/2023] Open
Abstract
Introduction Celiac disease (CD) is an autoimmune disorder that is provoked by the consumption of gluten in genetically vulnerable individuals. CD affects individuals worldwide with an estimated prevalence of 1% and can manifest at any age. Growth retardation and anemia are common presentations in children with CD. The objective of this study is to estimate the prevalence of CD in multiple "at risk groups" and to characterize children with CD, presented to a tertiary hospital in Dubai, United Arab Emirates (UAE). Methods The study reviewed medical charts of all patients <18 years who had received serologic testing for CD. The study was conducted at Al Jalila Children's Specialty Hospital in Dubai, UAE, from January 2018 to July 2021. Extracted information from medical records included sociodemographics, laboratory findings, clinical presentation, and any associated co-morbidities. The European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) criteria were used to identify patients with CD. Results During the study period, 851 paediatric patients underwent serological screening for CD, out of which, 23 (2.7%) were confirmed with CD. Of the 23 patients diagnosed with CD, 43.5% had no gastrointestinal symptoms. Diabetes type 1 (30.4%) followed by iron deficiency anaemia (30%) and Hashimoto thyroiditis (9%) were the most commonly associated comorbidities. The prevalence of CD among paediatric patients with autoimmune thyroiditis (12.5%) was 1.92-times higher than that among paediatric patients with diabetes type 1 (6.5%). Conclusion The results of this study show that almost three out of every 100 paediatric patients who were screened for CD were confirmed to have the condition. These findings highlight the importance of screening children who are at risk or present symptoms suggestive of CD, to ensure early diagnosis and appropriate management.

El Mouzan M, Assiri A, Al Sarkhy A. Gut microbiota predicts the diagnosis of celiac disease in Saudi children. World J Gastroenterol 2023; 29:1994-2000. [PMID: 37155522 PMCID: PMC10122788 DOI: 10.3748/wjg.v29.i13.1994] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/29/2022] [Accepted: 03/20/2023] [Indexed: 04/06/2023] Open
Abstract
BACKGROUND Celiac disease (CeD) is a multisystem immune-mediated multifactorial condition strongly associated with the intestinal microbiota.
AIM To evaluate the predictive power of the gut microbiota in the diagnosis of CeD and to search for important taxa that may help to distinguish CeD patients from controls.
METHODS Microbial DNA from bacteria, viruses, and fungi, was isolated from mucosal and fecal samples of 40 children with CeD and 39 controls. All samples were sequenced using the HiSeq platform, the data were analyzed, and abundance and diversities were assessed. For this analysis, the predictive power of the microbiota was evaluated by calculating the area under the curve (AUC) using data for the entire microbiome. The Kruskal-Wallis test was used to evaluate the significance of the difference between AUCs. The Boruta logarithm, a wrapper built around the random forest classification algorithm, was used to identify important bacterial biomarkers for CeD.
RESULTS In fecal samples, AUCs for bacterial, viral, and fungal microbiota were 52%, 58%, and 67.7% respectively, suggesting weak performance in predicting CeD. However, the combination of fecal bacteria and viruses showed a higher AUC of 81.8 %, indicating stronger predictive power in the diagnosis of CeD. In mucosal samples, AUCs for bacterial, viral, and fungal microbiota were 81.2%, 58.6%, and 35%, respectively, indicating that mucosal bacteria alone had the highest predictive power. Two bacteria, Bacteroides intestinalis and Burkholderiales bacterium 1-1-47, in fecal samples and one virus, Human_endogenous _retrovirus_K, in mucosal samples are predicted to be “important” biomarkers, differentiating celiac from nonceliac disease groups. Bacteroides intestinalis is known to degrade complex arabinoxylans and xylan which have a protective role in the intestinal mucosa. Similarly, several Burkholderiales species have been reported to produce peptidases that hydrolyze gluten peptides, with the potential to reduce the gluten content of food. Finally, a role for Human_endogenous _retrovirus_K in immune-mediated disease such as CeD has been reported.
CONCLUSION The excellent predictive power of the combination of the fecal bacterial and viral microbiota with mucosal bacteria alone indicates a potential role in the diagnosis of difficult cases of CeD. Bacteroides intestinalis and Burkholderiales bacterium 1-1-47, which were found to be deficient in CeD, have a potential protective role in the development of prophylactic modalities. Further studies on the role of the microbiota in general and Human_endogenous _retrovirus_K in particular are needed.

Abstract
BACKGROUND : The prevalence of celiac disease (CD) is relatively high in Saudi Arabia, and little is known about the accuracy of serological markers in the local population. This study aimed to assess the diagnostic performance of various serological markers for detecting CD in Saudi children and adults. METHODS We conducted a retrospective study of 148 CD patients and 512 controls to assess the diagnostic performances of IgA anti-tissue transglutaminase antibodies (TTG), IgG anti-TTG, IgA anti-deamidated gliadin peptide antibodies (anti-DGP), IgG anti-DGP, and endomysium antibodies (EMA). RESULTS : Immunoglobulin A (IgA) anti-TTG was the most sensitive test [98.9% (95% confidence interval (CI) 94.1-99.8%)], while EMA was the most specific [100%, 95%CI 98.6-100%]. By applying the criteria of IgA anti-TTG titers ≥10 × upper limit of normal (ULN) and positive EMA, 57.3% of patients could have avoided intestinal biopsy. IgG anti-DGP test had a sensitivity of 85.9% (95% CI = 77.3-91.5%) and a specificity of 93.5% (95% CI = (90.0-95.9%). Titers of IgA anti-TTG, IgA anti-DGP, and IgG anti-DGP were higher in CD patients with the Marsh 3c class than in those with the Marsh 3b and Marsh 3a classes. IgG anti-TTG and IgA anti-DGP had no additional diagnostic value. CONCLUSIONS : IgA anti-TTG and EMA are excellent CD markers in children and adults. The use of IgA anti-TTG titers ≥10 × ULN and positive EMA as criteria for CD diagnosis in children and adults might be a good alternative to intestinal biopsy.

Nutritional Status of Saudi Children with Celiac Disease Following the Ministry of Health’s Gluten-Free Diet Program. Nutrients 2022; 14:nu14142792. [PMID: 35889749 PMCID: PMC9315680 DOI: 10.3390/nu14142792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Revised: 07/01/2022] [Accepted: 07/06/2022] [Indexed: 02/04/2023] Open
Abstract
This study aimed to evaluate the nutritional status of Saudi children with celiac disease (CD) who followed the Ministry of Health’s gluten-free diet (GFD) program. This study involved 66 children with CD (29 boys and 37 girls) from 5 hospitals belonging to the Ministry of Health. Socioeconomic characteristics were obtained using a structured questionnaire. Anthropometric indices were measured using a body composition analyzer. Dietary intake was assessed using three 24 h dietary records. The biochemical parameters were determined in the hospitals’ laboratories. According to the findings, the majority of respondents had ages ranging from 10 to 13 years, a father and mother with a university education, a high family income, and 5 to 7 family members. Carbohydrates and protein intake for both genders were significantly higher than the DRI’s recommended dietary intake. However, the majority of nutrients consumed were at levels significantly lower than the DRI. Both genders had normal anthropometric indices, with girls having at significantly higher indices than boys. The biochemical parameters of both genders were comparable and within the normal range, except for vitamin D, which was below the normal range. The most important factors influencing nutritional status were age for both genders, and family income and number of family members for boys. In conclusion, data obtained for nutrient intake, anthropometric indicators, body composition, and biochemical analysis indicated that CD children following the Ministry of Health GFD program have a generally good nutritional status.

Abstract
Background Knowledge of microbiota in health is essential for clinical research on the role of microbiota in disease. We aimed to characterize the intestinal microbiota in healthy Saudi children. Methods In this community-based study, stool samples were collected from a randomly selected sample of 20 healthy school children of Saudi origin. The samples were frozen at -80°C till analysis. Bacterial DNA was isolated and libraries were prepared using the Illumina Nextera XT library preparation kit. Unassembled sequencing reads were directly analyzed and quantified for each organism's relative abundance. The abundance for each organism was calculated and expressed as the average relative percentage from phyla to species. Results The median age was 11.3 (range 6.8-15.4) years, and 35% of them were males. The three most abundant phyla were Firmicutes, Bacteroidetes, and Actinobacteria accounting for 49%, 26%, and 24%, respectively. The most abundant genera included Bifidobacterium, Bacteroides, and Blautia accounting for 18.9%, 12.8%, and 8.2%, respectively. Finally, the most abundant species included 14 species belonging to the genus Bacteroides and nine species belonging to Bifidobacterium. Conclusions The abundance of intestinal microbiome in healthy Saudi children is different from that of other populations. Further studies are needed to understand the causes of variation between populations, which might lead to new preventive methods and treatment strategies of diseases caused by microbial dysbiosis.

Abstract
Coeliac disease is a systemic disorder characterized by immune-mediated enteropathy, which is caused by gluten ingestion in genetically susceptible individuals. The clinical presentation of coeliac disease is highly variable and ranges from malabsorption through solely extra-intestinal manifestations to asymptomatic. As a result, the majority of patients with coeliac disease remain undiagnosed, misdiagnosed or experience a substantial delay in diagnosis. Coeliac disease is diagnosed by a combination of serological findings of disease-related antibodies and histological evidence of villous abnormalities in duodenal biopsy samples. However, variability in histological grading and in the diagnostic performance of some commercially available serological tests remains unacceptably high and confirmatory assays are not readily available in many parts of the world. Currently, the only effective treatment for coeliac disease is a lifelong, strict, gluten-free diet. However, many barriers impede patients' adherence to this diet, including lack of widespread availability, high cost, cross-contamination and its overall restrictive nature. Routine follow-up is necessary to ensure adherence to a gluten-free diet but considerable variation is evident in follow-up protocols and the optimal disease management strategy is not clear. However, these challenges in the diagnosis and management of coeliac disease suggest opportunities for future research.

Abstract
Celiac disease (CD) is an autoimmune intestinal disease caused by intolerance of genetically susceptible individuals after intake of gluten-containing grains (including wheat, barley, etc.) and their products. Currently, CD, with "iceberg" characteristics, affects a large population and is distributed over a wide range of individuals. This present review summarizes the latest research progress on the relationship between CD and gluten. Furthermore, the structure and function of gluten peptides related to CD, gluten detection methods, the effects of processing on gluten and gluten-free diets are emphatically reviewed. In addition, the current limitations in CD research are also discussed. The present work facilitates a comprehensive understanding of CD as well as gluten, which can provide a theoretical reference for future research.

Abstract
The prevalence of celiac disease (CD) in Indian children is not well documented, with most of the studies focusing on high-risk groups and not the general population. This study was conducted to determine the prevalence of CD in asymptomatic school children of Jaipur, Rajasthan. A cross- sectional study was conducted among healthy school children of Jaipur. Demographic data, symptoms, and signs including dermatological examination were recorded. The screening for CD was done by ELISA-based anti-tissue transglutaminase (tTG) immunoglobulin A (IgA) antibody testing. Children with high IgA anti-tTG underwent upper gastrointestinal endoscopy for small bowel biopsy from the second part of the duodenum. This study involved 575 subjects, out of which, 6 (1.04%) were found to be IgA tissue transglutaminase antibody (IgA-tTG) positive. All 6 subjects were found to be having changes consistent with celiac disease on duodenal biopsy. To conclude, the calculated prevalence of celiac disease was 1 in 96 subjects.

Abstract
BACKGROUND Although several studies have reported on the prevalence of micronutrients in Saudi Arabia, most frequently vitamin D and iron, they are either old or hospital- or primary health care center-based. The objectives of our study were to provide more updated data on the prevalence rate of micronutrients deficiency among the Saudi general pediatric population and to determine if there is an association between micronutrients deficiency and undernutrition. METHODS The present study is part of a cross-sectional mass screening study, "Exploring the Iceberg of Celiacs in Saudi Arabia" conducted among school-aged children (6-16 years) in 2014-2015. A sample of 7,931 children aged 6-16 years was randomly selected. We identified thin children [body mass index (BMI) z-score <-2 SD, for age and gender], using the WHO reference 2007. A case-control study was performed, where the sera of 182 thin children (cases) and 393 normal BMI children (controls) were tested for levels of iron, ferritin, vitamin D, zinc, selenium, and copper. RESULTS The prevalence of thinness was 3.5%. The two most common micronutrients deficient among Saudi children with normal BMI were iron (20%) and vitamin D (78%). Vitamin D levels were significantly higher among boys as compared to girls (39.6 nmol/L vs. 31.15 nmol/L; P < 0.001). Deficiency of copper, zinc, and selenium occurred in 0.25%, 1%, and 7.4% of the children with normal BMI. Comparisons between the cases and controls did not show statistically significant differences. CONCLUSION Vitamin D and iron deficiencies are still common forms of malnutrition in the Saudi community, that have remained unchanged over the past 20-30 years, while the intake of trace elements (zinc, copper, and selenium) is adequate as evident by normal serum levels in the vast majority of the investigated children. We could not observe a correlation between undernutrition and micronutrient deficiencies.

Abstract
Viruses are common components of the intestinal microbiome, modulating host bacterial metabolism and interacting with the immune system, with a possible role in the pathogenesis of immune-mediated diseases such as celiac disease (CeD). The objective of this study was to characterize the virome profile in children with new-onset CeD. We used metagenomic analysis of viral DNA in mucosal and fecal samples from children with CeD and controls and performed sequencing using the Nextera XT library preparation kit. Abundance log2 fold changes were calculated using differential expression and linear discriminant effect size. Shannon alpha and Bray–Curtis beta diversity were determined. A total of 40 children with CeD and 39 controls were included. We found viral dysbiosis in both fecal and mucosal samples. Examples of significantly more abundant species in fecal samples of children with CeD included Human polyomavirus 2, Enterobacteria phage mEpX1, and Enterobacteria phage mEpX2; whereas less abundant species included Lactococcus phages ul36 and Streptococcus phage Abc2. In mucosal samples however, no species were significantly associated with CeD. Shannon alpha diversity was not significantly different between CeD and non-CeD groups and Bray–Curtis beta diversity showed no significant separation between CeD and non-CeD samples in either mucosal or stool samples, whereas separation was clear in all samples. We identified significant viral dysbiosis in children with CeD, suggesting a potential role in the pathogenesis of CeD indicating the need for further studies.

Abstract
BACKGROUND Although intestinal fungi are known to interact with the immune system, the relationship between intestinal fungi and childhood celiac disease (CeD), an immune-mediated condition, has rarely been reported. AIMS The aim of this study was to describe gut fungal profiles in a cohort of children with new-onset CeD. METHODS Mucosal and fecal samples were collected from children with CeD and controls and subjected to metagenomics analysis of fungal microbiota communities. DNA libraries were sequenced using Illumina HiSeq platform 2 × 150 bp. Bioinformatic analysis was performed to quantify the relative abundance of fungi. Shannon alpha diversity metrics and beta diversity principal coordinate (PCo) analyses were calculated, and DESeq tests were performed between celiac and non-celiac groups. RESULTS Overall more abundant taxa in samples of children with CeD included Tricholomataceae, Saccharomycetaceae, Saccharomycetes Saccharomyces cerevisiae, and Candida, whereas less abundant taxa included Pichiaceae, Pichia kudriavzevii, Pneumocystis, and Pneumocystis jirovecii. Alpha diversity between CeD and control individuals did not differ significantly, and beta diversity PCo analysis showed overlap of samples from CeD and controls for both fecal or mucosal samples; however, there was a clear separation between mucosal and fecal overall samples CONCLUSIONS: We report fungal dysbiosis in children with CeD, suggesting a possible role in the pathogenesis of CeD. Further larger, controlled, prospective and longitudinal studies are needed to verify the results of this study and clarify the functional role of fungi in CeD.

Abstract
BACKGROUND Saudi Arabia has witnessed economic prosperity leading to changes in diet and lifestyle. Concurrent with these changes, the prevalence rates of overweight and obesity are rising. No recent data exist on the trends and pattern of growth impairment among Saudi children. We aimed to provide the most recent estimate of the prevalence of thinness and short stature among healthy school-aged children in Riyadh, Saudi Arabia, and to investigate the effect of parental socioeconomic status (SES) on growth impairment. METHODS A cross-sectional study was conducted in 2015 among schoolchildren in Riyadh. A sample of 7931 children (67% girls) aged 6-16 years was randomly selected. Body mass index (BMI) z-score <-2 SD and height z-score <-2 SD, for age and sex, using the WHO reference 2007, defined thinness and short stature, respectively. To assess the impact of SES on growth, we categorized SES into 4 levels by incorporating 4 main indicators: parents' educational level, family income, type of residence, and parents' jobs. RESULTS The prevalence of short stature was 15%, and the prevalence of thinness was 3.5%. Stratification of the thinness prevalence rate according to gender indicated that boys were significantly thinner than girls (4.7% versus 2.8%, P = 0.048). Short stature was significantly higher among children in the lower SES classes than among their counterparts in the higher SES classes. Parents of thin children were more likely to be less educated, have less income, live in apartments, and have a lower SES than parents of overweight and obese children. CONCLUSIONS The rate of thinness among Saudi children is low, similar to that in developed countries, and is significantly correlated with SES.

Reliability of the Multiplex CytoBead CeliAK Immunoassay to Assess Anti-tTG IgA for Celiac Disease Screening. Front Med (Lausanne) 2021; 8:731067. [PMID: 34621764 PMCID: PMC8491777 DOI: 10.3389/fmed.2021.731067] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2021] [Accepted: 08/05/2021] [Indexed: 01/16/2023] Open
Abstract
Background and Objective: The diagnosis of Celiac Disease (CD) is first based on the positivity for specific serological markers. The CytoBead CeliAK immunoassay simultaneously measures antibodies (IgA) directed to tissue transglutaminase (tTG), endomysium (EMA), and deamidated gliadin (DG), in addition to providing a control for total IgA levels. The aim of this study is to assess the reliability of this multiplex assay to detect anti-tTG IgA positive patients, compared with a conventional single-parameter enzyme-linked immunosorbent assay (ELISA). Methods: Serum samples from 149 pediatric patients were assessed by both CytoBead CeliAK immunoassay and ELISA, in order to evaluate their concordance for the measurement of anti-tTG IgA. Results: The measurement of anti-tTG IgA by CytoBead CeliAK immunoassay basically showed a complete concordance rate with the conventional and single-parameter ELISA, according to the respective cutoff values (3 U/ml and 10 U/ml). Conclusions: Our comparative analysis demonstrates a substantial equivalency between multiplex CytoBead CeliAK assay and the single-parameter conventional ELISA to assess anti-tTG IgA antibody in the context of the screening for CD in children. Importantly, CytoBead CeliAK assay could present some preanalytic, analytic, and economic advantages.

Abstract
OBJECTIVES Studies evaluating the correlation between tissue transglutaminase immunoglobulin antibody (TGA-IgA) levels and the degree of enteropathy in screening-detected coeliac disease (CD) patients from the general childhood population are scarce. The objectives of our study were to evaluate the correlation between the TGA-IgA titre and the degree of enteropathy and to evaluate whether the no-biopsy approach to diagnose CD in symptomatic patients proposed by the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition could be extended to asymptomatic CD patients diagnosed during mass screening studies. METHODS The present study is a sub-study of a cross-sectional mass screening study, "Exploring the Iceberg of Coeliacs in Saudi Arabia", conducted among school-aged children (6-15 years) in 2014-2015. The 93 biopsy-confirmed CD patients constituted the study cohort of the present study (mean age 11.4 ± 2.6 years; 24 males). TGA-IgA titres and endomysial antibodies (EMA) at the time of biopsy and grade of enteropathy were assessed, and human leukocyte antigen DQ 2.2/2.5/8 genotyping was performed. RESULTS Thirty-four patients had TGA-IgA titres >10× upper limit of normal (ULN; 36%); all had villous atrophy with positive EMA and DQ 2.2/2.5/8. The sensitivity and specificity of a TGA-IgA titre >10× ULN in correctly diagnosing CD was 100%. There was a significant positive correlation between the anti-TGA-IgA titre and the severity of enteropathy (P < 0.001). There was no significant difference in the TGA-IgA titre between the asymptomatic and symptomatic CD patients. CONCLUSIONS Our results provide evidence that a TGA-IgA titre >10× ULN correlates with villous atrophy in CD patients detected by mass screening.

Abstract
Celiac disease (CD) is triggered by both genetic and environmental factors. More than 1% of the world's population is affected by CD. In recent years, studies have confirmed a worldwide rising trend in CD prevalence. "Westernized diet" is one of the main factors of this increasing prevalence. However, the relationship between wheat consumption, its dynamics, and CD has not been adequately investigated on a global scale. This study aimed to perform a multilevel analysis of the association between wheat consumption and CD. Wheat consumption data from countries and continents were obtained from the database. The relative increase/decrease in wheat consumption over a long period (since 1961) and a short period (since 2004) were calculated using various statistical tools. The relationship between wheat consumption and celiac frequency was determined using the R-commander R package version 2.6-2. Pearson's correlation coefficient (r = 0.88) confirmed a high positive correlation between wheat consumption and the prevalence of biopsy-proven CD by estimating continent-wide wheat consumption data, but an insignificant correlation was found when the data were compared country-wide.

Abstract
OBJECTIVES Use of deamidated gliadin peptide (DGP) test kits as adjunctive to tissue-transglutaminase-IgA (TTG-IgA) for the diagnosis of celiac disease (CD) has been a controversial issue. The objectives of our study were to evaluate the diagnostic performance of DGP antibodies compared with TTG-IgA and to evaluate the correlation between DGP-antibody titers and degree of enteropathy. METHODS We included children who underwent endoscopy and biopsies because of positivity of any of the serology tests in the "celiac profile" (TTG-IgA, DGP-IgA, and DGP-IgG) from 2012 to 2019. We divided children into clinically suspected cases of CD (group 1) and asymptomatic cases screened as they were from a high-risk group (group 2). RESULTS Group 1 constituted 52 children and group 2 included 81 children (76 type-1 diabetes [T1D]). The sensitivity and positive-predictive value (PPV) of DGP-IgG in group 1 (90%, 98%) and group 2 (91%, 85.5%) were comparable with TTG-IgA (98%, 92% in group 1; 100%, 80% in group 2). By adding DGP-IgG to TTG-IgA, the performance of TTG-IgA has improved marginally in group 1 (sensitivity 100%, PPV 92.3%). All cases with DGP-IgG titer 2 times ULN in group 1, and >4 times ULN in group 2 had villous atrophy. All T1D patients with TTG IgA >10 times ULN had villous atrophy. CONCLUSIONS DGP-IgG assay did not add to the performance of TTG-IgA. DGP-IgG titer correlated with enteropathy. The diagnosis of CD can be made in asymptomatic T1D child with TTG-IgA titer >10 times ULN and positive endomyseal antibodies.

Abstract
BACKGROUND Celiac Disease (CD) is an autoimmune systemic disorder triggered by gluten in genetically susceptible individuals, which can lead to chronic malabsorption. Considering the changes in the manifestations of CD, this study aimed to determine anthropometric indices and clinical indications in children with CD. METHODS This cross-sectional study aimed to evaluate the children with CD who had referred to Imam Reza Celiac Clinic between 2016 and 2019. Totally, 361 children were eligible and their anti-tissue transglutaminase (TGA-IgA) level, weight, height, and Body Mass Index (BMI) were extracted from their records. The anthropometric indices were presented based on the criteria of the Center for Disease Control and Prevention (CDC) and World Health Organization (WHO). The prevalent symptoms were assessed, as well. RESULTS Based on the CDC's criteria, 18.3, 28.8, and 25.8% of the children had short stature, low body weight, and low BMI, respectively. These measures were obtained as 10, 22.4, and 13.9% according to the WHO's categorization respectively. Furthermore, the most common symptoms among the children were abdominal pain (56.5%), skeletal pain (28%), constipation (27.4%), and anemia (23.8%). CONCLUSION To sum up, the results clearly indicated that growth failure and low height, weight, and BMI were prevalent among the children with CD. Moreover, in addition to gastrointestinal symptoms, a considerable number of patients had skeletal pain and anemia.

Abstract
BACKGROUND/AIMS Little is known about the relationship between small intestinal bacterial overgrowth (SIBO) and celiac disease (CeD) in patients who are unresponsive to a gluten-free diet (GFD). This study aimed to determine the SIBO prevalence in patients with CeD who are unresponsive to a GFD. MATERIALS AND METHODS We conducted a case-control study from July 2012 to September 2014. We included 32 patients with CeD who were unresponsive to a GFD and 52 healthy age- and sex-matched controls. Demographic, clinical, and laboratory data were obtained from patients' medical records. Antitissue transglutaminase antibody determined by enzyme-linked immunosorbent assay was recorded, and lactulose hydrogen breath test (LHBT) was used to detect SIBO in all participants. Microbiological analysis, including jejunal aspirates obtained using upper endoscopy, was performed for only 20 patients with CeD. RESULTS A total of 10 (31%) of 32 patients with CeD and 4 (7.7%) of 52 controls tested positive for LHBT, with a statistically significant difference (p=0.007). Of 20 cultures, 3 (15%) were positive with no statistically significant correlation between the cultures and LHBT (p=0.05). In a subgroup analysis of children who were 18 years old or younger, 7/24 (29.2%) patients with CeD had a positive LHBT compared with 3/32 (9.4%) controls, but this difference was not statistically significant (p=0.08). CONCLUSION The prevalence of SIBO was 31% in unresponsive patients with CeD according to LHBT and 15% in the quantitative culture of the jejunal aspirate, which is comparable with the published Western literature.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is a multi-organ inflammatory disease associated with autoimmune diseases. The aim of the study is to assessed the frequency of celiac disease (CD) in adults and children with SLE (aSLE and cSLE, respectively) and compare them with rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) patients; the study also explored the clinical impact of CD serologic markers on SLE disease activity and severity. METHODS This was a cross-sectional study. Patients with SLE who had regular follow-up in rheumatology clinics were evaluated for laboratory and clinical variables using serology and the SLE Disease Activity Index (SLEDAI). To assess the occurrence of CD serology in cSLE and aSLE and the clinical impact of CD serologic markers on SLE, patients were tested for antigliadin (AGA), anti-endomysium (EmA) and anti-tissue transglutaminase (tTG) antibodies. RA and JIA patients were included for comparison. Duodenal biopsy was conducted in patients who exhibited CD markers. RESULTS The CD marker was found in 29 (11.6%) of the 250 patients. AGA was present in seven aSLE patients and tTG in two (11.1%). Among cSLE patients, the autoantibody was present in 17.6% (AGA in four, tTG in two, and EmA in three). For RA patients, five had AGA and tTG and one had EmA, with an overall positivity of 9.7%. Five JIA patients had AGA (four with EmA and five with tTG) with overall positivity of 10.9%; the serum IgA level was normal in all patients except one. Duodenal endoscopic biopsy was performed in patients with positive CD markers (two declined). Histologic confirmation of CD was reported in one RA and one JIA patient but in none of the SLE patients. There was no correlation between the presence of CD markers and autoantibodies in SLE. CONCLUSION CD antibodies did not influence SLE activity. Thus, SLE patients may not need to be screened for CD antibodies.

Abstract
Background and Aims Celiac disease (CD) is possibly the most common autoimmune disorder, which may lead to dietary problems in the Arab region. This paper is aimed at exploring the epidemiology of the celiac disease in Arab countries, including its prevalence, associated risk factors, and clinical patterns. Methods An extensive search of the literature was conducted from electronic databases such as PubMed, Embase, and Google Scholar. In total, 134 research papers were retrieved. We extracted studies published from January 1996 to December 2019. Our search was limited to studies published in English. Findings. The review included 35 studies with 22,340 participants from 12 countries and demonstrated a wide variation in the prevalence of CD. The highest prevalence among the general population (3.2%) was reported in Saudi Arabia, and the lowest (0.1%) was reported in Tunisia. Women demonstrated a higher prevalence of celiac disease relative to men. The peak age at diagnosis fell between 1 and 3 years and 9-10 years. Most studies focused on type 1 diabetes. Children with type 1 diabetes have a higher prevalence of CD (range from 5.5% to 20%), while the prevalence of CD in Down's syndrome patients was 1.1% and 10.7% in UAE and Saudi Arabia, respectively. Other autoimmune diseases associated with CD are thyroid disease and irritable bowel disease. The most widely recognized clinical presentation was an inability to flourish and poor weight gain, followed by short stature, abdominal pain, abdominal distension, bloating, and chronic diarrhea. Conclusion The prevalence of the celiac disease in Arab countries varies with sex and age. However, we found that celiac disease presented similar clinical characteristics independent of the geographic region. Longitudinal population-based studies are needed to better identify the true burden and determinants of celiac disease.

Abstract
Celiac disease (CD) is a gastrointestinal disorder whose genetic basis is not fully understood. Therefore, we studied a Saudi family with two CD affected siblings to discover the causal genetic defect. Through whole exome sequencing (WES), we identified that both siblings have inherited an extremely rare and deleterious CPED1 genetic variant (c.241 A > G; p.Thr81Ala) segregating as autosomal recessive mutation, suggesting its putative causal role in the CD. Saudi population specific minor allele frequency (MAF) analysis has confirmed its extremely rare prevalence in homozygous condition (MAF is 0.0004). The Sanger sequencing analysis confirmed the absence of this homozygous variant in 100 sporadic Saudi CD cases. Genotype-Tissue Expression (GTEx) data has revealed that CPED1 is abundantly expressed in gastrointestinal mucosa. By using a combination of systems biology approaches like protein 3D modeling, stability analysis and nucleotide sequence conservation analysis, we have further established that this variant is deleterious to the structural and functional aspects of CPED1 protein. To the best of our knowledge, this variant has not been previously reported in CD or any other gastrointestinal disease. The cell culture and animal model studies could provide further insight into the exact role of CPED1 p.Thr81Ala variant in the pathophysiology of CD. In conclusion, by using WES and systems biology analysis, present study for the first-time reports CPED1 as a potential causative gene for CD in a Saudi family with potential implications to both disease diagnosis and genetic counseling.

Saadah OI, ALNosani NM. Celiac disease in Saudi children with isolated short stature: is it rare or are we not screening rigorously enough? J Pediatr Endocrinol Metab 2020; 33:89-93. [PMID: 31804962 DOI: 10.1515/jpem-2019-0348] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2019] [Accepted: 11/11/2019] [Indexed: 11/15/2022]
Abstract
Background Celiac disease (CeD) is an immune-mediated enteropathy induced by gluten exposure in individuals with genetic susceptibility. Short stature (SS) can be the sole clinical manifestation of CeD, in the absence of gastrointestinal (GI) symptoms. This study aimed to determine the prevalence of CeD in Saudi Arabian children with SS. Patients and methods Medical records were reviewed in a total number of 275 retrospective cases (during the period 2002-2014) of children with isolated SS from King Abdulaziz University Hospital, Jeddah. Their serum samples were tested with tissue transglutaminase (tTG) antibodies. Patients with a positive serology were scheduled for an upper endoscopy and intestinal biopsy to confirm CeD diagnosis before starting a gluten-free diet (GFD). Clinical, anthropometric and laboratory data were recorded for all patients. Results A total of 275 children with SS were included. The mean age ± standard deviation (SD) was 9.4 ± 4.0 years (range, 2.6-16.9 years) and males constituted the predominant gender group (151/275; 54.9%) over females (124/275; 45.1%). The mean ± SD height for age z score (HAZ) was -2.9 ± 1.0.Thirty-eight (13.8%) had positive serology, and 16 (5.8%) had biopsy-proven CeD. Apart from the difference in duration of delayed bone age between CeD patients and CeD-negative serology subjects (mean ± SD, 39.6 ± 10.5 vs. 18.6 ± 16.8, p = 0.02), no other major difference in other clinical or laboratory parameters was evident. Conclusions The prevalence rate of CeD in Saudi Arabian SS children was 5.8%, which is comparable to published reports of a number of other countries. Regular screening of children with SS is therefore justifiable.

Efficacy Study of Anti-Endomysium Antibodies for Celiac Disease Diagnosis: A Retrospective Study in a Spanish Pediatric Population. J Clin Med 2019; 8:jcm8122179. [PMID: 31835690 PMCID: PMC6947542 DOI: 10.3390/jcm8122179] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Revised: 12/04/2019] [Accepted: 12/09/2019] [Indexed: 12/31/2022] Open
Abstract
The aim of this study was to assess the efficacy of anti-endomysium antibodies (EMA) as a serological marker for celiac disease (CD) diagnosis in a pediatric population. A retrospective study of pediatric patients who underwent a CD serological markers study: EMA and anti-tissue transglutaminase antibodies (anti-TG2). Clinical symptomatology, degree of histological lesion, human leukocyte antigen (HLA) haplotype compatible with CD (HLA DQ2 and/or DQ8), and final diagnosis were taken into account. We included 445 patients who were classified in two groups according to the final diagnosis. Group 1: 232 children with CD, 91.4% of whom exhibited small intestinal villous atrophy, 228 being EMA-positive and four EMA-negative. Group 2: 213 children with a non-CD diagnosis, 212 EMA negative and one EMA positive. Both antibodies, EMA and anti-TG2, reached similar sensitivities, 98% and 99% respectively, while EMA had a higher specificity (99%) than anti-TG2 (93%). By using both markers combined, compared to using anti-TG2 alone, 5.7% of patients are better diagnosed. However, when we compare the efficacy of EMA and anti-TG2 in asymptomatic and symptomatic patients, the sensitivity of EMA is 98% irrespective of symptoms, thus higher than for anti-TG2 ≥10 × upper limit of normal (ULN) (respectively 77% and 84%). Our results support the use of EMA to increase CD diagnostic accuracy in a non-biopsy approach, especially in asymptomatic children.

Abstract
OBJECTIVES It remains unknown what degree of risk is conferred by celiac disease (CD)-predisposing human leukocyte antigen (HLA)-DQ genotypes in Saudi Arabia compared with in Western countries. In this study, we aimed to determine the CD risk gradient associated with the HLA-DQ genotypes and to compare HLA-DQ genotypes between symptomatic patients with CD and screening-identified asymptomatic CD patients. METHODS We enrolled three groups of subjects, including 46 CD children diagnosed consecutively over the past 10 years, 54 CD children diagnosed during a mass screening of schoolchildren, and 192 healthy controls. All the participants were typed for the HLA-DQA1 and HLA-DQB1 genes by polymerase chain reaction sequence-specific oligonucleotide probes. RESULTS Comparing the patients with CD to controls, we identified 5 groups in the CD risk gradient: (i) very high risk associated with the DQ2.5/DQ8 genotype (odds ratio [OR] 46.93); (ii) high risk (homozygous DQ2.5, DQ2.5/DQ2.2; OR 4.12-5.04); (iii) intermediate risk (heterozygous DQ2.5, DQ8/DQ2.2; OR 1.61 and 1.67); (iv) low risk (DQ8, DQ2.2); and (v) very low risk (DQ2.x, DQX.5, DQX.x). Heterozygous DQ8 was more common in screening-identified group compared to symptomatic patients (13.0% vs 2.2%); however, other genotypes were very similar between the two groups. CONCLUSION The highest risk of developing CD in our Saudi Arabia population is associated with the DQ2.5/DQ8 genotype.

Abstract
BACKGROUND/AIMS The available studies on Helicobacter pylori (H. pylori) prevalence among healthy asymptomatic population across Saudi Arabia suffers from significant limitations. We conducted this large population-based study to estimate the H. pylori seropositivity rate among apparently healthy children in Saudi Arabia, using anti-H. pylori immunoglobulin A (IgA) and IgG serology tests, and to study the influence of H. pylori infection on growth. MATERIALS AND METHODS We conducted a cross-sectional study to screen apparently healthy school aged Saudi children (aged 6-15 years), attending primary and intermediate schools in Riyadh between 2014 and 2016, for H. pylori seropositivity by checking for the presence of anti-H. pylori IgG and IgA antibodies in serum specimens. RESULTS Out of 3551 serum specimens, 1413 cases tested seropositive for H. pylori organism (40%): 430 (12.2%) were both IgG and IgA positive, 212 (6%) and 771 (21.7%) cases showed isolated positivity for IgG or IgA, respectively. Male gender, older age, lower levels of socioeconomic status (SES), and family members >10 were significantly associated with H. pylori seropositivity. The proportion of participants with short stature was significantly more in the H. pylori seropositive group than the seronegative group (OR1.249, confidence interval [1.020-1.531], P= 0.033). There was no significant association between H. pylori seropositivity and gastrointestinal symptoms. CONCLUSION The prevalence of H. pylori seropositivity among apparently healthy Saudi children (40%) is intermediate compared with that in developed and developing countries. The Saudi pediatric population shows a predominant IgA-type immunological response to H. pylori infection.

Abstract
Up until the 1960s and 1970s, diarrhea, malabsorption syndrome, and failure to thrive were the presenting symptoms and signs of celiac disease (CD) in young infants; however this disease was also at the same time reported to be disappearing. Indeed, clinical childhood CD was seen to transform into a milder form, resulting in an upward shift in age at diagnosis during the 1970s (and years later for many countries). This changing pattern of CD presentation then altered the epidemiology of the disease, with major differences between and within countries observed. An awareness of the changing clinical nature of CD and use of case-finding tools to detect even clinically silent CD became an important factor in this changing epidemiology. Countries report both low and high prevalence but it seems to be on the increase resulting in a population-based level of 1-2%. This paper discusses the potential causes and environmental factors behind these observed clinical changes, identifying new clues from different studies published at the time this transformation took place. For instance, it was found that breastfeeding postponed the diagnosis of the disease but did not altogether prevent it. Moreover, gluten introduction at a young age, specifically at the mean age of 2 months, seemed to also have a clear impact in inducing malabsorption syndrome and failure to thrive in young infants in addition to other factors such as gluten intake volume and type of cereal present in the weaning food. Further, the impact of cow's milk and its high osmolarity might have played an important role; humanized milk formulas were not yet invented. Future epidemiological studies on the contributing environmental factors to the shift in CD presentation are thus recommended for countries in which these changing clinical features are still being observed.

Abstract
BACKGROUND/AIM To provide the most recent estimate of childhood obesity and determine the trend in childhood obesity in Riyadh city over the past two decades, by comparing our results with previous studies that published data comparable to our study in terms of geography, sample age (6-16 years), and use of World Health Organization (WHO) cut-offs to define obesity. PATIENTS AND METHODS A cross-sectional study was conducted in 2015 among school children in Riyadh city. A sample of 7930 children (67% girls) aged 6-16 years were randomly selected. Body mass index for age and gender above +1 and below +2 standard deviation scores (SDS) defined overweight (SDS, z-scores) and >+2 SD scores defined obesity. RESULTS The overall prevalence of overweight and obesity was 13.4% (14.2% for girls and 12% for boys; P= 0.02) and 18.2% (18% for girls and 18.4% for boys; P = 0.73), respectively. When compared with the WHO-based national prevalence rate of obesity reported in 2004 (≈9.3%), the obesity rate has doubled over a 10-year period. There was a significantly higher prevalence of obesity in adolescents (>11 years) than in children (20.2% vs 15.7%; P < 0.01). Overweight and obesity increased significantly with higher levels of socioeconomic status. Obese children were at 1.5 and 2 times risk of developing gas bloating and vomiting than non-obese children. CONCLUSION The prevalence of overweight and obesity has risen alarmingly among Saudi children and adolescents over the past decade and should make a strong case to initiate and monitor effective implementation of obesity prevention measures.

Abstract
Gluten triggers Celiac Disease (CD) and type I diabetes in genetically predisposed population of human leukocyte antigen DQ2/DQ8+ and associates with disorders such as schizophrenia and autism. Application of a strict gluten-free diet is the only well-established treatment for patients with CD, whereas the treatment for patients with celiac type I diabetes may be depend on the timing and frequency of the diet. The application of a gluten-free diet in patients with CD may contribute to the development of metabolic syndrome and nonalcoholic fatty liver disease and may also lead to a high glycemic index, low fiber diet and micronutrient deficiencies. The alteration of copper bioavailability (deficient, excess or aberrant coordination) may contribute to the onset and progress of related pathologies. Therefore, nutrient intake of patients on a gluten-free diet should be the focus of future researches. Other gluten-based therapies have been rising with interest such as enzymatic pretreatment of gluten, oral enzyme supplements to digest dietary gluten, gluten removal by breeding wheat varieties with reduced or deleted gluten toxicity, the development of polymeric binders to suppress gluten induced pathology.

Abstract
BACKGROUND/AIMS Celiac disease (CD) is an immune-mediated enteropathy triggered by gluten ingestion in genetically susceptible individuals. This study reports on the quality of life (QOL) of Saudi children and adolescents with CD. PATIENTS AND METHODS This is a case control study that included Saudi patients with CD, aged 9-18 years, who attended CD Clinic at KAU between February 2017 and July 2018. The study was conducted using the Short-Form (SF-36) questionnaire for all candidates, CD-specific QOL questionnaire for the CD patients group, and CD screen questionnaire for the control group. RESULTS Overall, 354 subjects were studied (111 CD patients and 243 control). Female subjects constituted 56.8% of both patient and control groups. In the generic SF-36 questionnaire, QOL was comparable between patients and controls in all domains except for the general health domain, which showed difference in favor of the controls (55.01 ± 26.41 and 62.96 ± 18.16, P = 0.005). We also found that males have lower QOL scores in the domains comprising health change (P = 0.02), physical functioning (P = 0.04, role functioning/emotional and emotional well-being (P = 0.049). The CD-specific QOL showed excellent and good scores for 79.3% of patients overall in the tested domains. Patients with poor adherence showed poor QOL in all generic (SF-36) domains but not in CD-specific domains. CONCLUSION The HRQOL for Saudi CD children on GFD is generally comparable to the healthy control with exception of the general health domain. Adherence to the GFD improves the generic (SF-36) QOL domains.

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

Abstract
BACKGROUND/AIM To determine the frequency of celiac disease (CD)-predisposing human leukocyte antigen (HLA)-DQ genotypes in the Saudi population, where the prevalence of CD is 1.5% as recently reported in a mass screening study. PATIENTS AND METHODS In a cross-sectional population-based study, a total of 192 randomly selected healthy school children (97 females, mean age 10.5 ± 2.2 years, all negative for tissue transglutaminase-IgA) were typed for D QA1 and D QB1 genes by polymerase chain reaction sequence-specific oligonucleotide probes. RESULTS Of the 192 children, 52.7% carried the high-risk CD-associated HLA-DQ molecules: homozygous DQ2.5 ( 2.6%), DQ2.5/DQ2.2 ( 4.7%), heterozygous DQ2.5 ( 28.15%), homozygous DQ8 ( 4.2%), DQ8/DQ2.2 ( 3.6%), and double dose DQ2.2 ( 9.4%). Low-risk CD-associated HLA-DQ molecules (single dose DQ2.2 and heterozygous DQ8) constituted 3.6% and 9.4%, respectively. Among the very low-risk groups, individuals lacking alleles that contribute to DQ2/DQ8 variants (33.5%), 13.5% carried only one of the alleles of the high-risk HLA-DQ2.5 heterodimer called "half-heterodimer" (HLA-DQA1*05 in 12% and HLA-DQB1* 02 in 1.5%), and 20.8% lacked all the susceptible alleles (DQX.x). Gender distribution was not significantly different among the CD-risk groups. CONCLUSION We report one of the highest frequencies of CD-predisposing HLA-DQ genotypes among healthy general populations (52.7%) worldwide, which might partly explain the high prevalence of CD in the Saudi community.

Abstract
BACKGROUND/AIMS There are no reports from Saudi Arabia documenting the picture of osteopathy in celiac disease (CD) and the adherence of physicians to the guidelines and recommendations to screen for bone disease. We conducted this study to document the prevalence of CD-related osteopathy and the Saudi physicians' adherence to the screening recommendations. PATIENTS AND METHODS We identified the biopsy proven CD cases diagnosed between 2003 and 2012. In addition to demographic data, we collected laboratory (serum calcium, phosphate, alkaline phosphatase, 25-dihydroxy vitamin D, and parathyroid hormone levels) and imaging [Dual-energy X-ray absorptiometry (DEXA)] data. Vitamin D levels of <50 nmol/L and 50-<75 nmol/L defined deficiency and insufficiency, respectively. T score (of lumbar spine and femoral neck) of ≤-2.5 defined osteoporosis and a score of ≤-1 and >-2.5 defined osteopenia. RESULTS We identified 80 children and 128 adults with CD. Only 42% of children and 67% of adults had their serum vitamin D level measured. DEXA was ordered in 7% of children and 36% of adults. Vitamin D deficiency was widely prevalent and significantly higher in adults (95.3%) than children (76.3%). Low bone mass density (BMD) in adults was 86.9% (45.6% with osteopenia and 41.3% with osteoporosis). CONCLUSIONS We document low adherence of physicians to recommended guidelines to recommendations to screen for osteopathy in CD. Vitamin D deficiency and low BMD are highly prevalent among Saudi CD patients. This may be a reflection of the low vitamin D stores in the Saudi general population.
