European Society for Pediatric Gastroenterology, Hepatology, and Nutrition Guidelines for the diagnosis of coeliac disease in 2012 / 中华实用儿科临床杂志

ABSTRACT

Diagnostic criteria for coeliac disease(CD) from the European Society for Paediatric Gastroenterology,Hepatology,and Nutrition were published in 1990.Since then,the autoantigen in CD,tissue transglutaminase had been identified;CD-specific antibody tests had improved.The perception of CD had changed greatly.A panel of 17 experts defined CD and developed new diagnostic criteria based on the Delphi process in 2012.The 2004 National Institutes of Health/Agency for Healthcare Research and Quality report and a systematic literature search on antibody tests for CD in paediatric patients covering the years 2004 to 2009 was the basis for the evidence-based recommendations on CDspecific antibody testing.In group of children with symptoms suggestive of CD,the diagnosis of CD is based on symptoms,positive serology,and histology that is consistent with CD.If immunoglobulin A anti-tissue transglutaminase type 2 antibody titers are high (＞ 10 times the upper limit of normal),then the option is to diagnose CD without duodenal biopsies by applying a strict protocol with further laboratory tests.In group of asymptomatic children at increased risk for CD,the diagnosis of CD is based on positive serology and histology.Human leukocyte antigen-DQ2 and human leukocyte antigen-DQ8 testing is valuable because CD is unlikely if both haplotypes are negative.The aim of the new guidelines was to achieve a high diagnostic accuracy and to reduce the burden for patients and their families.
