Abstract:
Objective To investigate the serum levels of soluble CD23 ( sCD23 ) and thrombopeietin (TPO) in chronic lymphocytic leukemia (CLL) and their correlation with other prognostic factors. Methods The serum levels of sCD23 and TPO of 25 CLL patients were detected with enzyme linked immunosorbent assay. Flow cytometry was employed to determine the expression of CD38 and ZAP-70 protein. Results TPO level in CLL patients was significantly higher than that in normal controls 67.22 - 1881.77 ng/L and 70. 29 - 147. 98 ng/L respectively, P =0. 003. sCD23 level in CLL patients was significantly higher than that in normal controls 129. 80-405. 31 U/ml and 0. 65 -32. 99 U/ml respectively, P =0. 000. TPO level was significantly correlated with Binet stage and CD38 expression. Patients in stage B and C had higher level of TPO than those in stage A 140. 57 -457.48 ng/L and 121.92 - 163.83 ng/L respectively, P =0.014,while TPO level was higher in patients with higher CD38 expression than in patients lower CD38 expression 113.23- 199. 10 ng/L and 141.34 -454. 92 ng/L respectively, P = 0. 033. No significant correlation of sCD23 and TPO levels with ZAP-70 protein, sex, age, peripheral lymphocyte count and lactate dehydrogenase were observed. Conclusion Serum TPO level might be a prognostic factor in CLL.
