摘要:

目的 探讨高敏肌钙蛋白Ths-cTnT)和肌酸激酶同工酶质量(CK-MB mass)对儿童病毒性心肌炎(VMC)的诊疗价值。方法 选择VMC患儿67例,分别于患儿出现心累、气促等临床症状24 d以及治疗1周后检测血清hs-cTnTCK-MB mass水平;同时测定54例急性胃肠炎患儿、53例上呼吸道感染患儿、50例肺炎患儿及55名健康体检儿童(正常对照组)的血清hs-cTnTCK-MB mass水平并做比较。采用受试者工作特征(ROC)曲线评估hs-cTnTCK-MB mass联合检测及单项检测时的敏感性和特异性。结果 急性胃肠炎组、急性上呼吸道感染组、肺炎组、正常对照组及VMC组入院时的血清hs-cTnT水平[中位数(四分位数)]分别为5.683.838.22)、5.033.006.57)、5.523.4410.19)、4.813.226.67)和58.5729.77160.20pg/mL;血清CK-MB mass水平[中位数(四分位数)]分别为2.291.722.96)、2.261.413.48)、2.591.813.62)、1.831.423.05)和7.404.3213.26ng/mL;各组间hs-cTnTCK-MB mass水平差异均有统计学意义(H值分别为115.1583.79P均<0.001),且VMC组入院时hs-cTnTCK-MB mass水平明显高于急性胃肠炎组、急性上呼吸道感染组、肺炎组和正常对照组(P均<0.001)。VMC组治疗后hs-cTnTCK-MB mass水平虽低于入院时(P均<0.001),但仍高于急性胃肠炎组、急性上呼吸道感染组、肺炎组和正常对照组(P均<0.001)。ROC曲线显示VMC入院时与治疗后hs-cTnTCK-MB mass联合检测的敏感性高于单独检测hs-cTnTP<0.05),但特异性差异无统计学意义(P>0.05)。结论 hs-cTnT用于诊断VMC有较高的敏感性和特异性,和CK-MB mass联合检测有更高的辅助诊断价值。

Abstract:

Objective To investigate the diagnosis and treatment significance of high-sensitivity cardiac troponin T hs-cTnTand creatine kinase isoenzyme mass CK-MB mass for viral myocarditis in children VMC. Methods Serum levels of hs-cTnT and CK-MB mass were determined in 67 patients with VMC measured within clinical symptoms for 2- 4 d and after treatment for 1 week), 54 children with acute gastroenteritis 53 children with acute upper respiratory tract infection 50 children with acute pneumonia and 55 healthy children healthy control group. The receiver operating characteristic ROC curve was used to evaluate the sensitivity and specificity of hs-cTnT determination CK-MB mass determination and the combined determination of hs-cTnT and CK-MB mass. Results Serum levels of hs-cTnT in acute gastroenteritis group acute upper respiratory tract infection group acute pneumonia group healthy control group and VMC group [median quartile] were 5.683.83 8.22), 5.033.00 6.57), 5.523.44 10.19), 4.813.22 6.67and 58.5729.77 160.20pg/mL respectively and serum levels of CK-MB mass [median quartile] were 2.291.72 2.96), 2.261.41 3.48), 2.591.81 3.62), 1.831.42 3.05 and 7.404.32 13.26 ng/mL respectively. There was statistical significance for hs-cTnT and CK-MB mass among the groups H=115.15 and 83.79P<0.001. Serum levels of hs-cTnT and CK-MB mass in VMC group after treatment were lower than those within clinical symptoms for 2- 4 d P<0.001), which were significantly higher than those in the acute gastroenteritis group acute upper respiratory tract infection group acute pneumonia group and healthy control group P<0.001. The ROC curve showed that the combined determination of hs-cTnT and CK-MB mass had higher sensitivity than hs-cTnT determination P<0.05), but without significant specificity P>0.05. Conclusions The hs-cTnT has high diagnosis sensitivity and specificity for VMC and the combined determination of hs-cTnT and CK-MB mass has high diagnosis significance.
