Serum complement levels were determined in seven patients with mixed (IgM–IgG) cryoglobulinaemia. All seven patients had either no measurable or very low levels of C'2. C'50 haemolytic units were determined in three patients and were also found low, although less striking. The mechanism by which the blood of these patients became depleted of C'2 could not be determined.
对7例混合性(IgM-IgG)冷球蛋白血症患者的血清补体水平进行了测定。所有7例患者的C'2水平均无法检测到或非常低。对3例患者测定了C'50溶血单位,发现其水平也较低,尽管不太明显。这些患者血液中C'2耗竭的机制尚无法确定。
