The serum pool prepared from patients with pauciarticular JRA and a history of anterior uveitis, but not from those without the eye disease, contained IgG antibodies which bound a low molecular weight iris antigen (LMW-IA) as measured by a modified ELISA. LMW-IA was protease-sensitive and contained at least four proteins of approximate molecular weights of 16, 13, 9 and 6.5 kD with no uronic acid or carbohydrate. Analysis of individual patient sera for IgG anti-LMW-IA antibody demonstrated that 1\/20 (5%) pediatric non-rheumatic disease controls (NRDC), 1\/19 (5.3%) non-uveitic pauciarticular JRA patients and 6\/21 (28.6%) uveitic pauciarticular JRA patients were positive by ELISA. Levels of anti-LMW-IA antibody did not correlate with serum IgG concentration, the presence of IgG antibody to soluble retinal S antigen (S antigen) or reactivity to the low molecular weight fraction of bovine choroid (LMW-C). Ten of 21 (47.6%) children with pauciarticular JRA and uveitis had serum antibody that reacted with LMW-IA and\/or retinal S antigen as compared to 1\/20 (5%) NRDC patients and 3\/19 (15.8%) patients with pauciarticular JRA uncomplicated by uveitis. Analysis of patient immunoreactivity to proteins of the anterior uveal tract may provide a greater understanding of pathogenic features related to arthritis-associated eye disease.<\/jats:p>","DOI":"10.1159\/000236431","type":"journal-article","created":{"date-parts":[[2009,9,15]],"date-time":"2009-09-15T08:22:24Z","timestamp":1253002944000},"page":"314-318","source":"Crossref","is-referenced-by-count":9,"title":["Iris Protein Antibodies in Serum of Patients with Juvenile Rheumatoid Arthritis and Uveitis"],"prefix":"10.1159","author":[{"given":"David W.C.","family":"Hunt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ross E.","family":"Petty","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fiona","family":"Millar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,9,2]]},"container-title":["International Archives of Allergy and Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/236431","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000236431","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T11:16:57Z","timestamp":1777634217000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000236431"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,2]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000236431","archive":["Portico"],"relation":{},"ISSN":["1018-2438","1423-0097"],"issn-type":[{"value":"1018-2438","type":"print"},{"value":"1423-0097","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,2]]}}}
