Serum IgA1 antibodies to bovine serum albumin (BSA) were detectable in 2\/30 healthy adults, in 3\/26 healthy children, and at high levels in 8\/11 children with coeliac disease, without relation to gluten exposure. IgA1 antibodies to ovalbumin (OA) and beta-lactoglobulin (BLG) at high titers were seen in one coeliac child but were otherwise low or absent. IgA2 antibodies to BSA were detectable in 28\/48 healthy subjects and in 8\/11 coeliac children. IgA2 antibodies to OA and BLG were measurable in a few samples from each group. IgA1 antibodies to the gluten component glycgli were found at low levels in 15\/56 normal sera, and anti-glycgli antibodies of the IgA2 subclass in 14\/48 sera from healthy persons, also at low levels. IgA1 anti-glycgli antibodies were measurable in 5\/11 sera from CD patients on a gluten-free diet. Elevated levels of IgA1 anti-glycgli antibodies were detected in all sera from CD patients challenged with gluten, except in 1 patient with a markedly reduced serum IgA level. In contrast, the IgA2 anti-glycgli antibody levels were unaffected. Thus, increased levels of IgA antibodies to dietary protein antigens in childhood coeliac disease were observed only within the IgA1 isotype.<\/jats:p>","DOI":"10.1159\/000234680","type":"journal-article","created":{"date-parts":[[2009,8,12]],"date-time":"2009-08-12T09:53:17Z","timestamp":1250070797000},"page":"247-253","source":"Crossref","is-referenced-by-count":11,"title":["ELISA Analysis of IgA Subclass Antibodies to Dietary Antigens"],"prefix":"10.1159","author":[{"given":"Michael","family":"Kemp","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steffen","family":"Husby","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mogens Lytken","family":"Larsen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sven-Erik","family":"Svehag","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,8,5]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/234680","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000234680","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T10:57:53Z","timestamp":1777633073000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000234680"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000234680","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,5]]}}}
