Changes of serum PCⅢ,Ⅳ-C,LN,TPO and EPO in patients with Leukemia / 中国基层医药

ABSTRACT

Objective To detect the levels of serum procollagen type Ⅲ (PCⅢ), Ⅳ collagen(Ⅳ-C) ,laminin ( LN ) , erythropoietin ( EPO ) and thrombopoietin ( TPO) in patients with acute and chronic leukemia. Methods PCⅢ , Ⅳ-Cand LN levels were determined by radioimmunoassay and TPO,EPO levels were determined by enzyme-linked immunosorbent assay,for 26 acute leukemia patients,16 chronic leukemia patients,and 16 normal controls. Results PC Ⅲ[(164.02 ± 118.53) μg/L], Ⅳ-C[(66.54 ± 19.48) μg/L] ,LN[(122.85 ±25.10)μg/L], EPO[(52.90±34.87)mU/ml]and TPO[(642.54±318.49)ng/L]levels of patients with acute and chronic leukemia were higher than that of the healthy control group before chemotherapy (P ＜ 0. 05). EPO [( 72. 21 ± 52. 15 )mU/ml]and TPO[(642.54 ±318.49)ng/L]levels of acute leukemia patients after treatment were significantly lower than before treatment(P＜0.05),while PC Ⅲ ,Ⅳ-C,LN levels had no significant difference(P ＞0.05). There was no significant difference before and after chemotherapy for PC Ⅲ, Ⅳ-C,LN,TPO and EPO levels of chronic leukemia patients (P＞ 0.05). Conclusion PC Ⅲ,Ⅳ-C,LN,TPO and EPO of patients with acute and chronic leukemia were abnormal, and dynamic monitoring of EPO and TPO levels could reflect the effect of AL chemotherapy, but conld not contribute to the prediction of CML blast crisis.
