慢性特发性血小板减少性紫癜患者血清转化生长因子β1测定的意义

目的 探讨血清转化生长因子β1(TGF-β1)在慢性特发性血小板减少性紫癜(CITP)中的临床意义.方法 采用ELISA法检测38例初治CITP患者治疗前后TGF-β1水平.结果 CITP患者治疗前TGF-β1水平(132.57±5.17)μg/L]明显高于对照组(76.81±4.42)μg/L],差异有统计学意义(P<0.01).经治疗缓解后血清TGF-β1水平(81.26±3.78)μg/L]与治疗前相比明显下降(P<0.01).未缓解者TGF-β1水平(123.49±4.31)μg/L]与初诊患者无明显差异(P>0.05).TGF-β1水平与血小板数呈负相关(r=-0.342,P<0.05),与巨核细胞数呈正相关(r=0.409,P<0.01).结论 TGF-β1参与了CITP的发病,检测TGF-β1水平变化有助于CITP病情判断,可作为疗效观察的辅助指标.

Clinical significance of serum level of transforming growth factor-beta 1 in patients with chronic idiopathic thrombocytopenic purpura

Objective To investigate clinical significance of transforming growth factor-beta 1 ( TGF-β1 ) in patients with chronic idiopathic thrombocytopenic purpura(CITP). Methods The serum level of TGF-β1 in 38 pa-tients with initial CITP were detected using enzyme-linked immunosorbent assay(ELISA). Results The serum level of TGF-β1 in initial patients with CITP was significantly higher than that of the controls ( 132.57±5.17) μg/L vs ( 76.81±4.42) μ/L] ( P <0.01 ). The serum level of TGF-β1 in those having good response after therapy was sig-nificantly lower than before treatment(81.26±3.78)μg/L] (P <0.01 ). There was no difference in TGF-β1 be-tween nonremission (123.49 ± 4.31 ) μg/L] and initial patients (P > 0.05 ). There was negative correlation between TGF-β1 and platelet count(r = -0. 342 ,P < 0.05 ) ,there was positive correlation between TGF-β1 and megakaryo-cyte count (r = 0.409, P < 0.01 ). Conclusions TGF-β1 partakes in the pathogenesis of CITP, the determination of which in patients with CITP is useful to judge the state of illness, which can be regarded as an assistant index of cur-ative effect.
