Circulating lymphocytes from 30 patients with sarcoidosis when stimulated in vitro with Kveim-induced macrophage migration factor, the Kmif test, produced a guinea-pig macrophage migration inhibition factor in 21 of 30 cases (70%). In those patients not on steroids the results showed a good correlation with the cutaneous Kveim test. One positive test was found in 16 normal subjects. Our results suggest that the Kmif test may prove a useful rapid alternative to the Kveim test.
用克维姆诱导的巨噬细胞游走因子(Kmif试验)在体外刺激30例结节病患者的循环淋巴细胞时,30例中有21例(70%)产生了豚鼠巨噬细胞游走抑制因子。在未使用类固醇的患者中,结果与皮肤克维姆试验显示出良好的相关性。16名正常受试者中有1例试验呈阳性。我们的结果表明,Kmif试验可能是一种有用的、可替代克维姆试验的快速方法。
