摘要: 目的: 通过观察急性淋巴细胞白血病患儿应用柔红霉素(daunorubicin, DNR) 化疗后其血浆N 末端脑利钠肽原(N-terminal pro-brain natriureticpeptide, NT-pro BNP) 水平的改变及应用左卡尼汀心肌保护药物后NT-pro BNP 水平的变化, 探讨能早期监测DNR 心肌毒性并可筛选出更好保护心肌药物的指标。方法: 选择2006-2008 年新诊断的急性淋巴细胞白血病患儿22 例, 均采用长春新碱+柔红霉素+左旋门冬酰胺酶+泼尼松(VDLP) 方案诱导化疗, 化疗期间分别应用左卡尼汀口服液(Levocarnitine oral solution) (治疗组) 或未予任何心肌保护药物(对照组) 。在应用DNR前后用交体基免疫分析法测定患儿血浆NT-proBNP 水平, 并同时常规检测患儿化疗前后心肌肌钙蛋白I(cTnI) 、心肌酶谱(LDH1 、CPK-MB) 及心电图(ECG) 。结果: 治疗组(L-CN 组) 患儿化疗后血浆NT-pro BNP 浓度从(53±11) pg/mL 增加到(162±27) pg/mL (P < 0.01) 。对照组从(51±10) pg/mL 增加到(194±38) pg/mL(P <0.01) 。两组化疗前NT-pro BNP 水平差异无统计学意义(P >0.05), 而化疗后治疗组(L-CN 组) 患儿血浆NT-pro BNP 水平较对照组低(P <0.05), 治疗组治疗后血浆NT-pro BNP 的改善情况优于对照组。两组化疗前后ECG 及cTnI 、LDH1 、CPK-MB 均无明显变化(P >0.05) 。结论: 在急性淋巴细胞白血病患儿应用DNR 化疗时, NT-pro BNP 可用于监测其对心脏的早期影响, 左卡尼汀对NT-pro BNP 的改善程度较对照组明显。

Abstract: AIM: To explore the value of N-terminal pro-brain natriuretic peptide (NT-pro BNP) in diagnosing the myocardiopathy induced by daunorubicin (DNR) and the more effective cardiac-protection drugs by investigating the changes of the NT-pro BNP levels after administrating DNR in children with acute lymphocytic leukemia. METHODS: Twenty-two children with acute lymphocytic leukemia who treated with DNR containing vincristine, L-asparaginase, prednisone, were randomly divided into two groups. The therapy group received L-CN as the cardiac-protection drug and the control group without protecting heart drug during chemotherapy with DNR. The level of NT-pro BNP in plasma was measured by immunoassay before and after using DNR and the cardiac troponin I(cTnI) and cardiac muscle enzyme (LDH1, CPK-MB) and ECG were detected before and after chemotherapy. RESULTS: The level of NT-pro BNP in plasma was increased from (53±11) pg/mL to (162±27) pg/mL (P <0.01) in the therapy group after chemotherapy and which in the control group was increased from (51±10) pg/mL to (194±38) pg/mL (P <0.01). There was no significant difference in the level of NT-pro BNP before chemotherapy between two groups. The level of NT-pro BNP in plasma was lower in the therapy group than that in the control group(P <0.05). The improving condition of the level of NT-pro BNP in the therapy group was better than that in the control group after chemotherapy. There were no significant difference in the ECG and cTnI and LDH1, CPK-MB in two groups before and after chemotherapy. CONCLUSION: NT-pro BNP can be served as a good indicator for DNR-induced myocardiopathy. Compared with control group, the improving condition of NT-pro BNP is obvious treated with levocarnitine.
