Management of bone health in patients with celiac disease: Practical guide for clinicians.

OBJECTIVE: To describe clinical issues related to bone health in patients with celiac disease (CD) and to provide guidance on monitoring bone health in these patients. SOURCES OF INFORMATION: A PubMed search was conducted to review literature relevant to CD and bone health, including guidelines published by professional gastroenterological organizations. MAIN MESSAGE: Bone health can be negatively affected in both adults and children with CD owing to the inflammatory process and malabsorption of calcium and vitamin D. Most adults with symptomatic CD at diagnosis have low bone mass. Bone mineral density should be tested at diagnosis and at follow-up, especially in adult patients. Vitamin D levels should be measured at diagnosis and annually until they are normal. In addition to a strict gluten-free diet, supplementation with calcium and vitamin D should be provided and weight-bearing exercises encouraged. CONCLUSION: Bone health can be adversely affected in patients with CD. These patients require adequate calcium and vitamin D supplementation, as well as monitoring of vitamin D levels and bone mineral density with regular follow-up to help prevent osteoporosis and fractures.

Prise en charge de la santé des os chez les patients atteints de la maladie cœliaque: Guide pratique à l'usage des cliniciens.

OBJECTIF: Décrire les enjeux cliniques liés à la santé des os chez les patients atteints de la maladie cœliaque (MC) et orienter la surveillance de la santé des os chez ces patients. SOURCES D'INFORMATION: Une recherche a été effectuée sur PubMed dans le but d'examiner les publications appropriées à la MC et la santé des os, y compris les lignes directrices publiées par des organisations professionnelles de gastro-entérologie. MESSAGE PRINCIPAL: Le processus inflammatoire et la malabsorption du calcium et de la vitamine D compromettent la santé des os chez les adultes et les enfants atteints de la MC. La masse osseuse est réduite chez la plupart des adultes dont la MC est symptomatique au diagnostic. Il faut mesurer la densité minérale osseuse au diagnostic et au suivi, surtout chez les adultes. Il faut mesurer le taux de vitamine D au diagnostic et tous les ans, jusqu'à ce qu'il soit normal. Outre un régime strict sans gluten, il faut assurer la supplémentation en calcium et en vitamine D, et encourager les exercices contre résistance. CONCLUSION: La santé des os peut être compromise chez les patients atteints de la MC. Ces patients ont besoin d'une supplémentation adéquate en calcium et en vitamine D, de même que de la surveillance du taux de vitamine D et de la densité minérale osseuse lors des suivis réguliers afin de prévenir l'ostéoporose et les fractures.

Celiac disease in patients with type 1 diabetes: screening and diagnostic practices.

OBJECTIVE: The purpose of this study was to investigate screening practices for celiac disease in patients with type 1 diabetes across North America. The research question investigated was whether diabetes centers screen for celiac disease in type 1 diabetes more frequently than other facilities. RESEARCH DESIGN AND METHODS: A survey with 27 questions on screening practices for celiac disease in patients with type 1 diabetes was designed by experts in celiac disease and diabetes. Surveys were sent by email to diabetes educators and dietitians throughout the United States and Canada between December 2010 and May 2011. RESULTS: There were 514 respondents from 484 endocrine clinics, diabetes clinics, private practices, community nutrition centers, and inpatient centers. Thirty-five percent of work locations screened for celiac disease, with endocrine clinics reporting screening at the highest frequency (80%). Tissue transglutaminase was the most common screening test used. The most frequently recommended treatment of confirmed celiac disease was a gluten-free diet. However, only 71% of respondents recommended biopsy in patients with positive serologies. Most respondents (55.3%) reported that the gluten-free diet resulted in symptom improvement in the majority of patients. CONCLUSIONS: Staff at endocrine clinics were more likely to suggest screening for celiac disease in patients with type 1 diabetes. Both low screening frequency as well as inconsistency in management of positive celiac disease serological tests indicated an increase in education regarding celiac disease in patients with type 1 diabetes is required. In addition uniform guidelines should be developed.

Home blood testing for celiac disease: recommendations for management.

OBJECTIVE: To provide recommendations for the management of patients who inquire about the Health Canada-approved, self-administered home blood tests for celiac disease or who present with positive test results after using the self-testing kit SOURCES OF INFORMATION: PubMed and the Cochrane Database of Systematic Reviews were searched from January 1985 to April 2008, using the subject headings diagnosis of celiac disease and management or treatment of celiac disease. Guidelines for serologic testing and confirmation of diagnosis of celiac disease by the American Gastroenterological Association and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition are used in this review. Level 1 evidence was used. MAIN MESSAGE: Although blood tests are helpful for screening purposes, the confirmatory test for celiac disease is a small intestinal biopsy. CONCLUSION: Patients whose blood tests for celiac disease provide positive results should have endoscopic small intestinal biopsies to confirm the diagnosis before starting a gluten-free diet.

Consumption of pure oats by individuals with celiac disease: a position statement by the Canadian Celiac Association.

The treatment of celiac disease is a strict adherence to a gluten-free diet for life. In the past, oats were considered to be toxic to individuals with celiac disease and were not allowed in a gluten-free diet. However, recent evidence suggests that oats that are pure and uncontaminated with other gluten-containing grains, if taken in limited quantities, are safe for most individuals with celiac disease. For adults, up to 70 g (1/2 to 3/4 cup) of oats per day and for children, up to 25 g (1/4 cup) per day are safe to consume. These oats and oat products must fulfill the standards for a gluten-free diet set by the Canadian Food Inspection Agency and Health Canada. The Canadian Celiac Association, in consultation with Health Canada, Agriculture & Agri-Food Canada and the Canadian Food Inspection Agency, has established requirements for growing, processing, and purity testing and labelling of pure oats. These strategies have led to the production of pure, uncontaminated oats for the first time in Canada. Oats and oat products that are safe for consumption by individuals with celiac disease and dermatitis herpetiformis are now commercially available in Canada.

The Canadian Celiac Health Survey.

The purpose of this study was to characterize the diagnostic process, frequency of associated disorders, family history, and impact of a gluten-free diet in individuals with celiac disease. All members of the Canadian Celiac Association (n=5240) were surveyed with a questionnaire. Respondents included 2681 adults with biopsy-proven celiac disease. The mean age was 56 years. Most common presenting symptoms included abdominal pain (83%), diarrhea (76%), and weight loss (69%). The mean delay in diagnosis was 11.7 years. Diagnoses made prior to celiac disease included anemia (40%), stress (31%), and irritable bowel syndrome (29%). Osteoporosis was common. Prior to diagnosis, 27% of respondents consulted three or more doctors about their symptoms. Delays in diagnosis of celiac disease remain a problem. Associated medical conditions occur frequently. More accurate food labeling is needed. Improved awareness of celiac disease and greater use of serological screening tests may result in earlier diagnosis and reduced risk of associated conditions.

Celiac disease: evaluation of the diagnosis and dietary compliance in Canadian children.

OBJECTIVES: We sought to characterize the clinical features at presentation as well as the associated disorders, family history, and evaluation of compliance with a gluten-free diet in children with celiac disease from across Canada. STUDY DESIGN: All members (n = 5240) of the Canadian Celiac Association were surveyed with a questionnaire. Of the 2849 respondents with biopsy-confirmed celiac disease, 168 who were < 16 years old provided the data reported here. RESULTS: The mean age when surveyed was 9.1 +/- 4.1 years, and 58% were female. Median age at diagnosis was 3.0 years with a range of 1 to 15 years. Presenting symptoms included abdominal pain (90%), weight loss (71%), diarrhea (65%), weakness (64%), nausea/vomiting (53%), anemia (40%), mood swings (37%), and constipation (30%). Almost one third of families consulted > or = 2 pediatricians before confirmation of the diagnosis. Before the recognition of celiac disease, other diagnoses received by these children included anemia (15%), irritable bowel syndrome (11%), gastroesophageal reflux (8%), stress (8%), and peptic ulcer disease (4%). A serological test was performed to screen for celiac disease in 70% of those in this population. Eight percent had either type 1 diabetes mellitus or a first-degree relative with celiac disease. Almost all respondents (95%) reported strict adherence to a gluten-free diet, and 89% noted improved health. Reactions after accidental gluten ingestion developed in 54% of the children between 0.5 and 60 hours after ingestion with a median of 2.0 hours. Reactions included abdominal discomfort (87%), diarrhea (64%), bloating (57%), fatigue (37%), headache (24%), and constipation (8%), and most displayed > 1 symptom. Although most adjusted well to their disease and diet, 10% to 20% reported major disruptions in lifestyle. Twenty-three percent felt angry all or most of the time about following a gluten-free diet. Only 15% avoided traveling all or most of the time, and during travel, 83% brought gluten-free food with them all of the time. More than half of the families avoided restaurants all or most of the time. Twenty-eight percent of the respondents found it extremely difficult to locate stores with gluten-free foods, and 27% reported extreme difficulty in finding gluten-free foods or determining if foods were free of gluten. Sixty-three percent of the respondents felt that the information supplied by the Canadian Celiac Association was excellent. Gastroenterologists provided excellent information to 44%, dietitians to 36%, and the family physician to 11.5%. When asked to select 2 items that would improve their quality of life, better labeling of gluten-containing ingredients was selected by 63%, more gluten-free foods in the supermarket by 49%, gluten-free choices on restaurant menus by 49%, earlier diagnosis of celiac disease by 34%, and better dietary counseling by 7%. CONCLUSIONS: In Canada, children with celiac disease present at all ages with a variety of symptoms and associated conditions. Delays in diagnosis are common. Most children are compliant with a gluten-free diet. A minority of these children experience difficulties in modifying their lifestyles, and gluten-free foods remain difficult to obtain.

The gluten-free diet: how to provide effective education and resources.

A strict gluten-free diet (GFD) for life is the only treatment for celiac disease (CD). This article reviews (1) the impact of the GFD on the quality of life of individuals with CD and their families; (2) the causes of poorly controlled CD; (3) the access to and source and quality of information provided by health professionals and other groups; (4) management strategies, including nutritional assessment and education guidelines; (5) a variety of resources available to individuals and health professionals; (6) innovative educational initiatives and partnerships; and (7) specific recommendations to address the increasing numbers of people with CD and the growing need for gluten-free (GF) foods and further education about CD and the GFD. Successful management of CD requires a team approach, including the person with CD and his or her family, physician, dietitian, and celiac support group; an individualized approach; understanding of quality of life issues; use of evidence-based, current information and resources; and regular follow-up to monitor compliance, nutritional status, and additional information and support. The physician must clearly communicate, with a positive attitude, an overview of CD and strongly emphasize the importance of a GFD for life. It is essential that the physician initiate an immediate referral to a dietitian with expertise in CD for nutritional assessment, diet education, meal planning, and assistance with the adaptation to the challenging new gluten-free lifestyle. Good dietary compliance will reduce the risk of further complications and associated health care costs and improve quality of life in patients with CD.
