Abstract

Sera from 104 children with JA with different onset-types of disease were evaluated for 19S IgM RF by the LFT, hidden 19S IgM RF by the hemolytic assay, ANA by HEp-2 cell substrate, and levels of IC by the C1qSPA. Their relationship to active disease was determined. Classical 19S IgM RF were detected by the LFT in only seven patients. All were late-onset polyarticular females. Hidden 19S IgM RF were detected by the hemolytic assay in the separated IgM-containing fraction in 55 patients of all onset-types. Clinical activity correlated with the presence of hidden 19S IgM RF in 82% of cases. ANA, using the HEp-2 cell substrate, were found in 61 patients, the majority showing a speckled, immunofluorescent pattern. ANA were noted in all RF positive patients and in nine of 10 patients with iridocyclitis. IC were found in 39 patients, and correlation with clinical activity occurred in 54% of cases.
