Of 15 juvenile rheumatoid arthritis patients tested, 8 were seropositive and 7 were seronegative, but 6 of the seronegative patients had hidden 19S IgM\u2010RF. Ten patients (5 seropositive and 5 with hidden 19S IgM\u2010RF) demonstrated RF\u2010PFC in their peripheral blood (range 15 to &gt;200 RF\u2010PFC\/10<jats:sup>6<\/jats:sup> mononuclear cells).
