Abstract
BACKGROUND Controversy exists about optimal methods for duodenal biopsy in diagnosis of celiac disease (CD), in terms of both number of samples and anatomic location. The reliability of duodenal bulb biopsy has been questioned given that normal bulb architecture may mimic disease. However, multiple studies have reported patients with CD have histopathological lesions limited to proximal changes in the duodenal bulb alone. METHODS We retrospectively compared duodenal and duodenal bulb histology in a population of paediatric patients with CD and compared with a population of nonceliac controls at Stollery Children's Hospital, 2010 to 2012. RESULTS Fifty-seven paediatric patients diagnosed with CD and 16 nonceliac controls were included in the study. Fifty-three celiac patients (93.0%) had histopathology consistent with CD (modified Marsh score of 3A, 3B or 3C) in the duodenal bulb. The modified Marsh classification differed significantly between duodenum and duodenal bulb in nine celiac patients (15.8%). Of these, five (8.8%) had Marsh 3 in the bulb and Marsh 0 in the distal duodenum. Among controls, no patients had villous atrophy in either the distal duodenum or duodenal bulb, and all patients had a modified Marsh score of 0 at both sites. CONCLUSIONS The results of this study reinforce that duodenal bulb samples are critically important for diagnosing CD in paediatric patients. We suggest that duodenal bulb samples be submitted in separate containers from distal duodenal samples to facilitate accurate interpretation. In contrast to prior reports, we found villous blunting and intraepithelial lymphocytosis are actually uncommon findings in paediatric patients with nonceliac gastrointestinal disorders.

Abstract
Introduction: Treatment of celiac disease is a strict life-long gluten-free diet (GFD). The GFD is complex, and counseling by a dietitian is essential. The number of new referrals for GFD education has increased. We studied the feasibility of GFD teaching using distributed education.Methods: The IWK Health Center in Halifax is the only tertiary-care pediatric hospital in the 3 Maritime provinces with GFD experienced dietitians. Families travel long distances to attend teaching sessions. Families outside the Halifax area were offered to participate in the 2.5-hour education sessions held once a month via live videoconference link at their regional hospitals. All participants were surveyed with a 10-item questionnaire assessing the content and delivery and usefulness of information.Results: Over a 6-month period, 39 families attended the sessions, 21 locally and 18 at distributed sites across the Maritimes. The survey was completed by 26 participants (67%). All participants at both sites strongly agreed or agreed that their setting was good for learning and the information provided was easy to understand. There were no significant differences between the 2 groups on any individual questions in the 2 domains assessed (all P > 0.06).Conclusions: Distributed education on GFD is feasible and as effective as in person education. It affords convenience and savings to families by reducing travel costs.

Abstract
Celiac disease (CD) is an immune-mediated enteropathy triggered by dietary ingestion of gluten in genetically susceptible patients. CD is often diagnosed by a "case-finding" approach of symptomatic patients. In recent times, the diagnostic paradigm has shifted to investigate patients who may be asymptomatic, but are at high risk of developing CD due to shared genetic susceptibilities. These high-risk groups include first-degree relatives of CD patients and patients with Type 1 diabetes mellitus, autoimmune thyroid disease, Down's syndrome, and Turner syndrome. Moreover, CD is often diagnosed as the cause of iron deficiency anemia or unexplained chronic diarrhea. Although screening for CD with serological tests is not recommended for the general population, it should be considered in these special populations. In this review, we explore screening for CD among high-risk groups in light of recent research and development in the CD arena.

Abstract
OBJECTIVES To conduct a systematic review and meta-analysis that defines the worldwide incidence of celiac disease (CD) and examines temporal trends. METHODS MEDLINE and EMBASE were searched for population-based studies reporting the incidence of CD in the overall population, children, or adults. No limits were placed on year or language of publication. Studies solely examining at-risk populations (e.g., patients with type 1 diabetes) were excluded. Random-effects models were performed to meta-analyze sex- and age-specific incidence in the 21st century. Temporal trend analyses assessed the average annual percent change in CD incidence over time. RESULTS Of 11,189 citations, 86 eligible studies were identified for inclusion, of which 50 were deemed suitable for analyses. In the 21st century, the pooled female incidence of CD was 17.4 (95% confidence interval [CI]: 13.7, 21.1) (I = 99.5%) per 100,000 person-years, compared with 7.8 (95% CI: 6.3, 9.2) (I = 98.6%) in males. Child-specific incidence was 21.3 per 100,000 person-years (95% CI: 15.9, 26.7) (I = 99.7%) compared with 12.9 (95% CI: 7.6, 18.2) (I = 99.9%) in adults. Pooling average annual percent changes showed the incidence of CD to be increasing by 7.5% (95% CI: 5.8, 9.3) (I = 79.6%) per year over the past several decades. DISCUSSION Incidence of CD is highest in females and children. Overall, the incidence has been significantly rising in the latter half of the 20th century and into the 21st century throughout the Western world. Population-based studies in Africa, Asia, and Latin America are needed to provide a comprehensive picture of the global incidence of CD.

Abstract
OBJECTIVES Celiac disease (CD) is an autoimmune disease that requires lifelong adherence to a gluten-free diet (GFD). Adherence to the GFD in childhood may be poor and adversely influence health-related quality of life (HRQOL). The study purpose was to determine sociodemographic and socioeconomic factors influencing adherence to the GFD and HRQOL in a multiethnic cohort of youth with CD. METHODS A multisite (Edmonton, Hamilton, Toronto) study examining child-parent HRQOL in youth with CD (n = 243) and/or mild gastrointestinal complaints (GI-CON; n = 148) was conducted. Sociodemographic (age, child-parental age/education/ethnicity/place of birth), anthropometric (weight, height, body mass index), disease (diagnosis, age at diagnosis, duration, Marsh score, serology), household characteristics (income, family size, region, number of children/total household size), HRQOL (Peds TM/KINDL and Celiac Disease DUX), GI Complaints (PedsQL: Gastrointestinal Symptom Scale) and gluten intake were measured. RESULTS Younger age (<10 years), non-Caucasian ethnicity (parent/child), and presence of GI symptoms were associated with the highest rates of adherence to the GFD in CD children (P < 0.05). CD children (parent/child) had higher HRQOL (average, composite domains) than GI-CON (P < 0.05), but CD children were comparable to healthy children. Lack of GI symptoms, non-Caucasian ethnicity and age (<10 years) were associated with increased HRQOL in composite/average domains for CD (P < 0.05). CONCLUSIONS Child-parent perceptions of HRQOL in a multiethnic population with CD are comparable to healthy reference populations, but significantly higher than in parent/child GI-CON. Adherence to the GFD in ethnically diverse youth with CD was related to GI symptoms, age of the child, and ethnicity of the parent-child.

Abstract
OBJECTIVES Limited pediatric data exist examining the trend and predictors of antitissue transglutaminase (atTG) normalization over time in children with celiac disease (CD). We aimed to evaluate time to normalization of atTG in children after CD diagnosis, and to assess for independent predictors affecting this duration. METHODS A retrospective chart review was completed in pediatric patients with CD diagnosed from 2007 to 2014 at the Stollery Children's Hospital Celiac Clinic (Edmonton, Alberta, Canada). The clinical predictors assessed for impact on time to atTG normalization were initial atTG, Marsh score at diagnosis, gluten-free diet compliance (GFDC), age at diagnosis, sex, ethnicity, medical comorbidities, and family history of CD. Kaplan-Meier survival analysis was completed to assess time to atTG normalization, and Cox regression to assess for independent predictors of this time. RESULTS A total of 487 patients met inclusion criteria. Approximately 80.5% of patients normalized atTG levels. Median normalization time was 407 days for all patients (95% confidence interval [CI: 361-453]), and 364 days for gluten-free diet compliant patients (95% CI [335-393]). Type 1 diabetes mellitus (T1DM) patients took significantly longer to normalize at 1204 days (95% CI [199-2209], P < 0.001). Cox regression demonstrated T1DM (hazard ratio = 0.36 [0.24-0.55], P < 0.001) and higher baseline atTG (hazard ratio = 0.52 [0.43-0.63], P < 0.001) were significant predictors of longer atTG normalization time. GFDC was a significant predictor of earlier normalization (OR = 13.91 [7.86-24.62], P < 0.001). CONCLUSIONS GFDC and lower atTG at diagnosis are predictors of earlier normalization. Patients with T1DM are less likely to normalize atTG levels, with longer normalization time. Additional research and education for higher-risk populations are needed.

Abstract
AIM To determine the sensitivity of macroscopic appearance for predicting histological diagnosis at sites other than duodenum in pediatric celiac disease (CD).
METHODS Endoscopic and histologic findings in pediatric patients undergoing upper endoscopy for first-time diagnosis of CD at Stollery Children’s Hospital from 2010-2012 were retrospectively reviewed.
RESULTS Clinical charts from 140 patients were reviewed. Esophageal and gastric biopsies were taken in 54.3% and 77.9% of patients, respectively. Endoscopic appearance was normal in the esophagus and stomach in 75% and 86.2%. Endoscopic esophageal diagnoses were eosinophilic esophagitis (EE) (11.8%), esophagitis (7.9%), glycogenic acanthosis (1.3%) and non-specific abnormalities (3.9%). Endoscopic gastric diagnoses were gastritis (8.3%), pancreatic rest (0.9%), and non-specific abnormalities (4.6%). Histology was normal in 76.3% of esophageal and 87.2% of gastric specimens. Abnormal esophageal histology was EE (10.5%), esophagitis (10.5%), glycogenic acanthosis (1.3%) and non-specific (1.3%). Gastritis was reported in 12.8% of specimens. Sensitivity and specificity of normal endoscopy for predicting normal esophageal histology was 86.2% and 61.1%, and for normal gastric histology was 87.4% and 21.4%.
CONCLUSION In the absence of macroscopic abnormalities, routine esophageal and gastric biopsy during endoscopy for pediatric CD does not identify major pathologies. These findings have cost and time saving implications for clinical practice.

Abstract
Celiac disease (CD) is an autoimmune reaction to gluten, leading to intestinal inflammation, villous atrophy, and malabsorption. It is the most common autoimmune gastrointestinal disorder, with an increasing prevalence. A life-long gluten-free diet (GFD) is an effective treatment to alleviate symptoms, normalize autoantibodies, and heal the intestinal mucosa in patients with CD. Poorly controlled CD poses a significant concern for ongoing malabsorption, growth restriction, and the long-term concern of intestinal lymphoma. Achieving GFD compliance and long-term disease control poses a challenge, with adolescents at particular risk for high rates of noncompliance. Attention has turned toward innovative management strategies to improve adherence and achieve better disease control. One such strategy is the development of multidisciplinary clinic approach, and CD is a complex life-long disease state that would benefit from a multifaceted team approach as recognized by multiple national and international bodies, including the National Institutes of Health. Utilizing the combined efforts of the pediatric gastroenterologist, registered dietitian, registered nurse, and primary care provider (general practitioner or general pediatrician) in a CD multidisciplinary clinic model will be of benefit for patients and families in optimizing diagnosis, provision of GFD teaching, and long-term adherence to a GFD. This paper discusses the benefits and proposed structure for multidisciplinary care in improving management of CD.

Abstract
Background Celiac disease (CD) is a major public health problem with estimated 1-3% prevalence in the general population. In recent years an increase in CD prevalence has been reported both in Sweden and worldwide. This study aimed at examining the annual incidence rate of biopsy-proven celiac disease among children in Sweden over a 36-year period, to assess variations by age, sex and birth cohort, and to assess the clinical impact of these changes. Methods The National Swedish Childhood CD Register was used to identify 9107 children aged 0–14.9 years who were diagnosed with CD during the period 1973 to 2009. From 1973 to 1990 the register covered 15% of the nation, this increased to 40% during 1991–1997; a full national coverage was obtained from 1998 onwards. Estimations for the annual incidence rate, cumulative incidence and clinical impact by age groups, calendar month and birth cohorts were made. Results CD incidence is continuing to increase in the child population aged 2–14.9 years. A continued variation in CD incidence was observed in children aged 0–1.9 years, characterized by a marked decrease in most recent years. The median age at diagnosis has increased from 1.0 year in the 1970s to 6.8 years in 2009. The average number of new cases has risen from ~200 during 1973–1983 to ~600 during 2004–2009. In the birth cohorts of 2000–2002 the cumulative incidence even exceeded that of the epidemic cohorts at comparable ages. The highest cumulative incidence was observed in the birth cohorts of 1985–1995 and 2000–2002. Conclusions CD risk varies between birth cohorts, suggesting cyclic environmental and/or lifestyle risk factors in CD etiology. More research on underlying risk factors is required in order to move forward with preventive strategies.

Abstract
Celiac disease is a food-induced enteropathy resulting from exposure to gluten in genetically predisposed individuals. The non-celiac gluten sensitivity (NCGS) is a less known syndrome whose prevalence is under-estimated. The last decades have seen changes in the clinical presentation of both diseases. One possible explanation is that changes in the gluten-rich cereals themselves were the principal causes. Celiac-triggering gluten proteins are indeed expressed to higher levels in modern cereals while non-triggering proteins are expressed less. Sophisticated hybridization techniques have been used to produce new strains of modern wheat, the most high-yielding of which have since made their way into human foods in the absence of animal or human safety testing. The dramatic changes in the clinical presentation of celiac disease and NCGS have taken place when new cereal hybrids were introduced into human foods. This is a critical medical and environmental issue which needs to be investigated by appropriate studies.

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
BACKGROUND Celiac disease and eosinophilic esophagitis are usually considered to be separate gastrointestinal diseases; however, it appears that they may coexist more often than would be expected. It is unknown whether eosinophilic esophagitis in patients with celiac disease responds to a gluten-free diet. OBJECTIVES To examine the clinical, endoscopic and histological features of children with both conditions to evaluate whether eosinophilic esophagitis responds to a gluten-free diet. METHODS From January 1, 2009, to June 30, 2011, the medical records of children <18 years of age diagnosed with eosinophilic esophagitis and⁄or celiac disease were reviewed. Patients with clinical, endoscopic and histological diagnoses of both diseases were identified and included. These findings were analyzed, as were laboratory results, treatment and follow-up. RESULTS During the study period, there were 206 celiac disease patients, 86 eosinophilic esophagitis patients and nine (4.4% of total celiac) patients with both diagnoses. Gluten-free diet was the primary treatment for both conditions in seven of nine (78%) cases. In six of these seven (86%) patients, no endoscopic or histological improvement of eosinophilic esophagitis was observed, while in one patient, histological remission of esophageal eosinophilia occurred while on a gluten-free diet. CONCLUSION The prevalence of eosinophilic esophagitis in patients with celiac disease was 4.4%, confirming a higher than expected prevalence of eosinophilic esophagitis compared with the general population. In patients with celiac disease, a gluten-free diet did not appear to induce remission of coexistent endoscopic and histological features of eosinophilic esophagitis.
