Abstract
Advances in the field of celiac disease have led to a better understanding of the disease, but it remains underdiagnosed and poses a daily challenge to clinicians to make a timely diagnosis. This study aims to analyze and describe diagnosis characteristics, diagnosis delay, and the factors influencing this delay in Moroccan children. Our study included 324 children diagnosed during the study period from January 01, 2010, to December 30, 2019, at the Department of Pediatrics, Hassan II University Hospital in Fez, Morocco. Data were collected using a collection grid and then analyzed using SPSS 26 software (IBM Corp., Armonk, NY). The results showed a female predominance (n=197, 60.8%), with a diagnosis age of 73.8±46.8 months. The mean age onset of symptoms was 51.3±41.2 months, and the diagnosis delay was 22.2±22.6 months, with only 32.7% (n=106) diagnosed less than 12 months after symptom onset. The most common consultation reason was diarrhea (n=149, 46%) and growth delay (n=105, 32.4%) and 50.5% (n=98) of parents consulted a pediatrician first. The three clinical, serologic, and histologic criteria made it possible to agree on the diagnosis, with the clinical profile dominated by the digestive form at 84.9% (n=279), serologic with the presence of IgA transglutaminase antibodies (95.7%; n=310), and histologic with villous atrophy at 91.7% (n=297). Unfortunately, 14.8% (n=48) of the children were diagnosed with a celiac crisis. The multivariate logistic regression analysis showed that as symptoms onset age increased, so did the risk of late diagnosis (OR=0.96, 95% CI: 0.94 to 0.97, p<0.001). Age of diagnosis was also associated with delayed diagnosis (OR=19.68, 95% CI: 8.77 to 44.15, p<0.001). The combination of these variables and the diagnosis delay argues in favor of adopting a diagnosis strategy that includes raising awareness among healthcare professionals of the need to identify typical and atypical cases early in order to reduce the adverse effects of late diagnosis and the complications that can result. This methodology for improving diagnoses may also unearth previously unknown aspects of celiac disease in Moroccan children.

Abstract
BACKGROUND Coeliac disease is an autoimmune disorder triggered by ingesting gluten. It affects approximately 1% of the UK population, but only one in three people is thought to have a diagnosis. Untreated coeliac disease may lead to malnutrition, anaemia, osteoporosis and lymphoma. OBJECTIVES The objectives were to define at-risk groups and determine the cost-effectiveness of active case-finding strategies in primary care. DESIGN (1) Systematic review of the accuracy of potential diagnostic indicators for coeliac disease. (2) Routine data analysis to develop prediction models for identification of people who may benefit from testing for coeliac disease. (3) Systematic review of the accuracy of diagnostic tests for coeliac disease. (4) Systematic review of the accuracy of genetic tests for coeliac disease (literature search conducted in April 2021). (5) Online survey to identify diagnostic thresholds for testing, starting treatment and referral for biopsy. (6) Economic modelling to identify the cost-effectiveness of different active case-finding strategies, informed by the findings from previous objectives. DATA SOURCES For the first systematic review, the following databases were searched from 1997 to April 2021: MEDLINE® (National Library of Medicine, Bethesda, MD, USA), Embase® (Elsevier, Amsterdam, the Netherlands), Cochrane Library, Web of Science™ (Clarivate™, Philadelphia, PA, USA), the World Health Organization International Clinical Trials Registry Platform ( WHO ICTRP ) and the National Institutes of Health Clinical Trials database. For the second systematic review, the following databases were searched from January 1990 to August 2020: MEDLINE, Embase, Cochrane Library, Web of Science, Kleijnen Systematic Reviews ( KSR ) Evidence, WHO ICTRP and the National Institutes of Health Clinical Trials database. For prediction model development, Clinical Practice Research Datalink GOLD, Clinical Practice Research Datalink Aurum and a subcohort of the Avon Longitudinal Study of Parents and Children were used; for estimates for the economic models, Clinical Practice Research Datalink Aurum was used. REVIEW METHODS For review 1, cohort and case-control studies reporting on a diagnostic indicator in a population with and a population without coeliac disease were eligible. For review 2, diagnostic cohort studies including patients presenting with coeliac disease symptoms who were tested with serological tests for coeliac disease and underwent a duodenal biopsy as reference standard were eligible. In both reviews, risk of bias was assessed using the quality assessment of diagnostic accuracy studies 2 tool. Bivariate random-effects meta-analyses were fitted, in which binomial likelihoods for the numbers of true positives and true negatives were assumed. RESULTS People with dermatitis herpetiformis, a family history of coeliac disease, migraine, anaemia, type 1 diabetes, osteoporosis or chronic liver disease are 1.5-2 times more likely than the general population to have coeliac disease; individual gastrointestinal symptoms were not useful for identifying coeliac disease. For children, women and men, prediction models included 24, 24 and 21 indicators of coeliac disease, respectively. The models showed good discrimination between patients with and patients without coeliac disease, but performed less well when externally validated. Serological tests were found to have good diagnostic accuracy for coeliac disease. Immunoglobulin A tissue transglutaminase had the highest sensitivity and endomysial antibody the highest specificity. There was little improvement when tests were used in combination. Survey respondents (n = 472) wanted to be 66% certain of the diagnosis from a blood test before starting a gluten-free diet if symptomatic, and 90% certain if asymptomatic. Cost-effectiveness analyses found that, among adults, and using serological testing alone, immunoglobulin A tissue transglutaminase was most cost-effective at a 1% pre-test probability (equivalent to population screening). Strategies using immunoglobulin A endomysial antibody plus human leucocyte antigen or human leucocyte antigen plus immunoglobulin A tissue transglutaminase with any pre-test probability had similar cost-effectiveness results, which were also similar to the cost-effectiveness results of immunoglobulin A tissue transglutaminase at a 1% pre-test probability. The most practical alternative for implementation within the NHS is likely to be a combination of human leucocyte antigen and immunoglobulin A tissue transglutaminase testing among those with a pre-test probability above 1.5%. Among children, the most cost-effective strategy was a 10% pre-test probability with human leucocyte antigen plus immunoglobulin A tissue transglutaminase, but there was uncertainty around the most cost-effective pre-test probability. There was substantial uncertainty in economic model results, which means that there would be great value in conducting further research. LIMITATIONS The interpretation of meta-analyses was limited by the substantial heterogeneity between the included studies, and most included studies were judged to be at high risk of bias. The main limitations of the prediction models were that we were restricted to diagnostic indicators that were recorded by general practitioners and that, because coeliac disease is underdiagnosed, it is also under-reported in health-care data. The cost-effectiveness model is a simplification of coeliac disease and modelled an average cohort rather than individuals. Evidence was weak on the probability of routine coeliac disease diagnosis, the accuracy of serological and genetic tests and the utility of a gluten-free diet. CONCLUSIONS Population screening with immunoglobulin A tissue transglutaminase (1% pre-test probability) and of immunoglobulin A endomysial antibody followed by human leucocyte antigen testing or human leucocyte antigen testing followed by immunoglobulin A tissue transglutaminase with any pre-test probability appear to have similar cost-effectiveness results. As decisions to implement population screening cannot be made based on our economic analysis alone, and given the practical challenges of identifying patients with higher pre-test probabilities, we recommend that human leucocyte antigen combined with immunoglobulin A tissue transglutaminase testing should be considered for adults with at least a 1.5% pre-test probability of coeliac disease, equivalent to having at least one predictor. A more targeted strategy of 10% pre-test probability is recommended for children (e.g. children with anaemia). FUTURE WORK Future work should consider whether or not population-based screening for coeliac disease could meet the UK National Screening Committee criteria and whether or not it necessitates a long-term randomised controlled trial of screening strategies. Large prospective cohort studies in which all participants receive accurate tests for coeliac disease are needed.

Abstract
Trichobezoars are hairballs that combine with food residue in the digestive tract as a result of ingesting hair. A 17-year-old girl was admitted to the emergency department with abdominal pain and vomiting for 3 days. She had been having digestive difficulty and bloating for the previous 2 months. An abdominal radiograph demonstrated air-fluid levels consistent with ileus, and an ultrasound showed hyperechoic material in the stomach and ileum. Computed tomography demonstrated images of trapped air which was considered diagnostic of a bezoar. At laparotomy, a large mass was removed from the stomach. As the bezoar extended through the pylorus and duodenum and there were mobile masses palpable in the ileum, it required a second incision to remove them. For some years she had had a habit of swallowing hair which she found on her pillow and there was a history of an obsessive personality trait and hyperactivity for which she agreed to attend a psychiatric clinic.Abbreviations: BMI: body mass index; CT: computed tomography; Hb: haemoglobin; IV: intravenous; WHO: World Health Organization.

Abstract
BACKGROUND & AIMS Anemia is common in patients with celiac disease (CD) and a frequent mode of presentation. Guidelines recommend screening patients with iron-deficiency anemia (IDA) for CD. However, the reported prevalence of CD in patients with IDA varies. We performed a systematic review to determine the prevalence of biopsy-verified CD in patients with IDA. METHODS We performed a systematic review of articles published in PubMed Medline or EMBASE through July 2017 for the term "celiac disease" combined with "anemia" or "iron deficiency." We used fixed-effects inverse variance-weighted models to measure the pooled prevalence of CD. Meta-regression was used to assess subgroup heterogeneity. RESULTS We identified 18 studies composed of 2998 patients with IDA for inclusion in our analysis. Studies originated from the United Kingdom, United States, Italy, Turkey, Iran, and Israel. The crude unweighted prevalence of CD was 4.8% (n = 143). Using a weighted pooled analysis, we found a prevalence of biopsy-confirmed CD of 3.2% (95% confidence interval = 2.6-3.9) in patients with IDA. However, heterogeneity was high (I2 = 67.7%). The prevalence of CD was not significantly higher in studies with a mean participant age older or younger than 18 years or in studies with a mixed-sex vs female-predominant (≥60%) population. On meta-regression, year of publication, female proportion, age at CD testing, and prevalence in the general population were not associated with the prevalence of CD in patients with IDA. In the 8 studies fulfilling all our quality criteria, the pooled prevalence of CD was 5.5% (95% confidence interval = 4.1-6.9). CONCLUSIONS In a systematic review and meta-analysis, we found that approximately 1 in 31 patients with IDA have histologic evidence of CD. This prevalence value justifies the practice of testing patients with IDA for CD.

Abstract
BACKGROUND Celiac disease is an enteropathy caused by dietary gluten. The combination of serologic, genetic and histologic data has led to description of other categories of this disease. OBJECTIVE There are a number of patients with iron deficiency anemia (IDA) that do not respond to iron treatment and may be repeated for many times, Therefore, we aimed to investigate celiac disease in this group. METHODS In this cross sectional transverse prospective study from August 2011 to February 2013, in a Pediatric care clinic affiliated to Shiraz University of Medical Sciences, 184 children including 92 IDA patients who responded to treatment using iron supplement, 45 non-responding iron deficient patients, and 47 healthy individuals, with the maximum age of 18 years, with written consent from their parents, participated in serologic screening (with Anti-TTG antibody and anti-Endomysial antibody) for celiac disease. Patients with at least one positive serology test underwent multiple mucosal biopsy from bulb and duodenum. RESULTS Among 184 participants, 19 (10.3%) subjects had positive serologic test for celiac disease, including 13 (28.9%) patients in the group with refractory IDA, 5 (5.4%) patients in the group with treated IDA, and 1 patient in the healthy group. The frequency of positive serologic test in the group with IDA resistant to treatment was prominently higher than the other two groups (P<0.001). Among the patients with positive serologic celiac test who underwent endoscopy and biopsy, no histologic evidence of celiac disease was seen. They were diagnosed as potential celiac disease. CONCLUSION Frequency of potential celiac disease in patients with refractory IDA was higher than control the subjects. Therefore, we recommend serologic screening for early detection and minimizing the complications of celiac disease and repeated iron therapy for this group.

Abstract
OBJECTIVES The purpose of this study was to evaluate the prevalence of celiac disease in adult patients with iron-deficiency anemia of obscure origin. METHODS One hundred and sixty-one consecutive patients with iron-deficiency anemia of obscure origin were evaluated. Tissue transglutaminase antibodies levels were done and duodenal biopsies were scored according to Marsh classification. Diagnosis was based on positive IgA anti-tissue transglutaminase antibodies and abnormal histopathology. Gluten-free diet (GFD) was adviced for celiac disease patients. One hundred and sixty healthy blood donors were tested for IgA anti-tissue transglutaminase antibodies, and positive controls were subjected to endoscopic duodenal biopsy. RESULTS Tissue transglutaminase antibodies were positive in 13 (8 %) patients with iron-deficiency anemia of obscure origin and 4 (2.5 %) in control group (p = 0.026) (odds ratio 3.42; 95 % confidence interval [CI]: 1.092-10.743). All 13 patients (8 %) and 2 out of 4 positive controls (1.25 %) had histopathology findings of celiac disease (p = 0.004). Duodenal biopsy showed Marsh grade 1 in 4, grade 2 in 4 (30.77 %), 3a in 1 (7.70 %), 3b in 2 (15.38 %), and 3c in 2 (15.38 %) patients. A statistically significant correlation was found between lower hemoglobin concentration and higher Marsh grading (Spearman's rho = -0.946, p = 0.001). Celiac disease patients adhered to GFD and after 6 months mean (SD) hemoglobin levels increased from 7.42 ± 0.96 to 10.47 ± 0.80 g/dL (p- < 0.001). CONCLUSION Patients with iron-deficiency anemia of obscure origin had increased prevalence of celiac disease. Gluten-free diet improved anemia in celiac disease patients irrespective of grade of duodenal involvement.

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

Abstract
Idiopathic Pulmonary Hemosiderosis (IPH) is characterized by the triad of iron deficiency anemia, pulmonary infiltrates and haemoptysis with no recognizable cause. Since the first description of its association with Celiac Disease (CD) by Lane and Hamilton in 1971, only a few isolated cases have been reported in literature. Although it has been considered an uncommon association of two disease entities, recent reports indicate that prevalence of celiac disease is as high as one percent. Further, individually both celiac disease and IPH are known to present as refractory anemia only. We are reporting a young adult with Lane Hamilton Syndrome, who realized that he was having significant gastrointestinal complaints only when they disappeared on gluten free diet (GFD). This case report reiterates the fact that celiac disease should be considered in all patients of IPH because of the therapeutic implications. Further on review of literature, we believe that covert hemoptysis may be responsible for disproportionately severe anemia in patients of celiac disease. Thus, prevalence of this association may be more than currently believed. Further research in this regard may improve our understanding of pathogenesis of celiac disease.
