Serum from 109 coal workers with simple pneumoconiosis, 114 with progressive massive fibrosis, and 130 with normal chest radiographics as control subjects was examined for rheumatoid and antinuclear factors, and antibodies against both native human IgG and Mycobacterium tuberculosis. A significantly greater prevalence of autoantibodies was observed in subjects with pneumoconiosis than in control subjects; however, a rheumatoid factor prevalence of 16% with observed inthe control subjects. No serologic differences were observed between subjects with simple pneumoconiosis and those with progressive massive fibrosis.
检测了109名单纯尘肺煤矿工人、114名进行性大块纤维化患者以及130名胸部X线正常者（作为对照）的血清，以检测类风湿因子、抗核因子以及抗天然人IgG和结核分枝杆菌的抗体。尘肺患者自身抗体的患病率显著高于对照；然而，对照中类风湿因子的患病率为16%。单纯尘肺患者和进行性大块纤维化患者之间未观察到血清学差异。
