急性淋巴细胞性白血病患儿脑脊液铁蛋白

Cerebrespinal fluid ferritin in the child patients with acute lymphatic leukemia

研究目的发探讨白血病患儿脑脊液铁蛋白（CSF－Ft）含量的变化及其临床意义。研究方法经骨髓检查确诊的急性淋巴细胞性白血病患儿42例，分为3组，Ⅰ组（诱导治疗期不伴中枢神经系统白血病）14例，Ⅱ组（完全缓解期不伴中枢神经系统白血病）24例，Ⅲ组（合并中枢神经系统白血病）18例。病毒性脑炎（病脑）组17例，对照组15例均无中枢神经系统疾病。用放射免疫分析法检测CSF－Ft及血清铁蛋白。结果Ⅰ、Ⅱ、Ⅲ组、病脑组和对照组患者CSF－Ft含量分别为7．03±2．21μg／L，6．75±1．94μg／L，31．06±8．85μg／L，7．26±1．83μg／L和6．52±1．57μg／L。Ⅲ组患儿LCSF－Ft含量明显高于其它组（P均＜0．01）。10例中枢神经系统白血病患儿，随病情好转其CSF－Ft水平渐下降。结论CSF－Ft检测对中枢神经系统白血病诊断有重要价值，并可做为评价中枢神经系统白血病治疗效果的重要指标。

Objcetives To sparch for the change of cerebrospinal fluid ferritin (CSF-Ft) content and its clinical significance.Methods The 42 patients with acute lymphatic leukemia(ALL)diagnosed by bone marrow biopsy were divided into 3 groups. There were 14 cases in Ⅰ group [introduced therapy stage without central nervous system leukemia(CNSL)7, 24 cases in Ⅱgroup (complete remission stage without CNSL) and 18 cases in Ⅲ grotip (with CNSL). There were 17 patients with viral encephalitis in viral encephalitis group and 15 patients without central nervous system oisease in control group. The CSF-Ft and SFt were determined by radioimmunoassay.Results The CSF-Ft contents of Ⅰ、Ⅱ、Ⅲ 、viral encepbalitis and control groups are 7.03 ±2.21 μg/L,6.75 ±1.94μg/L, 31.06 ± 8.85μg/L, 7.26±1.83μg/L and 6.52 ±1.57μg/L. The CSF-Ft content in Ⅲ group are bigher than that in the other group (P<0.01). Along with the improvemant of the disease, the CSF-Ft level is gradually decresed.Conclusion CSF-Ft determination has important value for the diagnosis of CNSL, and could be regarded as an important target evaluating the therapeutic effect of CNSL.
