Abstract:
In order to investigate the relation of serum immunoglobulin (Ig) level to age, sex, disease stages and prognosis in chronic lymphocytic leukemia (CLL) patients, the levels of serum IgG, IgA and IgM in 83 CLL patients were detected by immune rate turbidimetry. the expressions of CD38 and ZAP-70 in CLL cells were determined by multi-parameter flow cytometry (FCM). The results showed that among the 83 CLL patients, the IgG, IgA and IgM levels were reduced in 12 (14.5%), 26 (31.3%) and 34 cases (41.0%) respectively. The incidence of Ig reduction was higher in Binet C stage than that in Binet A and B (p=0.011). There was higher incidence of Ig reduction in high-risk group of Rai stage than that in low-risk group (p=0.011). The positive rate of CD38 or ZAP-70 was significantly higher in Ig reduction group than that in normal Ig level group (p=0.033 and p=0.038 respectively). The positive rate of CD38 and ZAP-70 was also higer in advanced disease, and among them the positive rate of ZAP-70 expression in Binet C stage was obviously higer than Binet A and B (p=0.047). Nonetheless, there was no significant relationship of Ig level with gender and age (p>0.05). It is concluded that the function of humoral immunity in CLL patient is closely related to the disease stages. The serum Ig detection seems important for evaluating immunologic state and prognosis of CLL patients.
