Acute blast crisis occurred in two patients with previously well-confirmed chronic lymphocytic leukaemia. The finding by direct immunofluorescence of membrane-bound monoclonal immunoglobulins on the surface of the blast cells showed that they were related to B cells in the same way as the proliferating lymphocytes in most patients with chronic lymphocytic leukaemia. In one patient the surface monoclonal IgM detected on both the lymphocytes and the blast cells had the same rheumatoid antibody activity, supporting the concept that the leukaemic cells found during the acute and chronic phases of the disease originated from the same clone.
两名先前确诊为慢性淋巴细胞白血病的患者发生了急性原始细胞危象。通过直接免疫荧光法发现原始细胞表面存在膜结合单克隆免疫球蛋白,这表明它们与大多数慢性淋巴细胞白血病患者的增殖淋巴细胞一样,与B细胞相关。在一名患者中,在淋巴细胞和原始细胞上检测到的表面单克隆IgM具有相同的类风湿抗体活性,这支持了疾病急性和慢性阶段发现的白血病细胞起源于同一克隆的概念。
