European guidelines suggest that in children and adolescents with symptoms which are compatible with coeliac disease, the diagnosis can be made without the need for an intestinal biopsy if anti-tTG antibodies titres are very high (10 times the upper limit of normal). [9]
Because of the major implications of a diagnosis of coeliac disease, professional guidelines recommend that a positive blood test is still followed by an endoscopy/gastroscopy and biopsy. A negative serology test may still be followed by a recommendation for endoscopy and duodenal biopsy if clinical suspicion remains high. [21] [41] [93]
Anti-gliadin antibodies were one of the first serological markers for coeliac disease. Problematic with AGA is the typical sensitivity and specificity was about 85%. Gliadin peptides which are synthesized as the deamidated form have much higher sensitivity and specificity, creating 2 serological tests for CD that approach biopsy diagnostic in ...
Children with celiac disease often present with symptoms like abdominal distension or bloating, as well as failure to thrive, anemia and diarrhea. Because these symptoms are vague and can be related to many other conditions or food allergies, celiac disease can be difficult to diagnose unless there is a family history to help as a cue.
Autoimmune conditions related to gluten include celiac disease, dermatitis herpetiformis, and gluten ataxia.There is research showing that in people with gluten ataxia early diagnosis and treatment with a gluten-free diet can improve ataxia and prevent its progression. [9]
"Guideline for the Diagnosis and Treatment of Celiac Disease in Children: Recommendations of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition". Journal of Pediatric Gastroenterology and Nutrition. 40 (1): 1– 19. doi: 10.1097/00005176-200501000-00001. PMID 15625418. S2CID 14805217.
[3] [20] Rarely, patients present with EATL who have no gastrointestinal symptoms of celiac disease but rather with extra-intestinal manifestations that are associated with the disease such as dermatitis herpetiformis, [3] psoriasis, other chronic skin conditions, dental enamel defects, gluten-induced cerebellar ataxia, arthritis, and ...
Most attention to anti-transglutaminase antibodies is given with respect to celiac disease. A recent study of children published in 2007 demonstrated that the level of ATA in correlates with the scalar Marsh score for the disease in the same patient. [9] High levels of ATA are found in almost all instances of celiac disease. [10]
