Serum gammaglobulin level, the presence of rheumatoid factor and of anti-nuclear antibodies were re-examined after 8 to 12 years in families of 21 seropositive rheumatoid arthritis patients. In the time 8 members of the families developed rheumatoid arthritis and the number of persons with elevated serum gammaglobulins increased. Rheumatoid tests yielded variable results. No relationship could be demonstrated between development of disease symptoms and the earlier presence of rheumatoid factor.
对21例血清学阳性类风湿性关节炎患者的家族成员在8至12年后重新检测血清γ球蛋白水平、类风湿因子和抗核抗体。在此期间，家族中有8名成员患上了类风湿性关节炎，血清γ球蛋白升高的人数也增加了。类风湿检测结果不一。疾病症状的出现与早期类风湿因子的存在之间未发现关联。
