在我国,皮肤粘膜淋巴结综合征的报告日渐增多,但其病因未明。本文报告典型的皮肤粘膜淋巴结综合征6例。其中1例在急性期及恢复期进行了外一斐氏反应检查,其OX_k滴度分别为1:80及1:640,由于本例排除了引起OX_k阳性的其他疾病,故本例OX_k滴度的8倍升高,提示皮肤粘膜淋巴结综合征可能由立克次氏体引起。 In our country, the report of mucocutaneous lymph node syndrome is increasing day by day, but its etiology is unknown. This article reports a typical case of mucocutaneous lymph node syndrome in 6 cases. One case of acute Pegasus during the acute phase and recovery of the reaction, the OX_k titers were 1:80 and 1: 640, as this example exclude OX_k-positive other diseases, so the case of OX_k titers 8-fold increase, suggesting that mucocutaneous lymph node syndrome may be caused by rickettsia.
