Abstract

The specificity and sensibility of IgA and IgG alfagliadin antibody test (AaGA) for screening, diagnosis and follow-up of childhood coeliac disease has been evaluated. We have compared AaGA test to D-xylose blood test and at last we have examined the false positive and negative results given by the test. Two groups of subjects were considered: 1) 90 children with untreated coeliac disease (21 newly diagnosed (I stage), 50 in gluten withdrawal (II stage), 19 in challenge (III stage); 2) 255 disease controls including: 157 healthy controls; 31 children with gastroenterological disorders other than coeliac disease; 31 children with food allergy and atopic dermatitis; 36 children with "constitutional" short stature (without GH deficiency and with normal intestinal mucosa). The sensibility of AaGA test in the first stage of coeliac disease has been of 95.2% for the IgG class antibody and 90.4% for the IgA class; on the other hand the showed a specificity of 83.6% for IgG class antibody and 96.9% for IgA class. In only two newly diagnosed coeliac children we have found false negative results: in the first case the patient was IgA-deficient, in the second the age was above 3 years. AaGA IgA resulted positive only in the 12.9% of the group of gastroenterological and atopic controls; particularly most cases were affected by multiple food allergies and two patients by chronic autoimmune disease of small intestine.(ABSTRACT TRUNCATED AT 250 WORDS)
