摘要 目的分析感染性疾病新生儿心肌损害标志物水平的变化及其临床意义。方法选取2015年1月至2016年6月首都医科大学附属北京安贞医院新生儿病房收治的患感染性疾病足月新生儿213例,包括肺炎165例(肺炎组)、败血症48例(败血症组),自然分娩121例(自然分娩组)、剖宫产92例(剖宫产组)。入院后24h内及治疗7d后取患儿静脉血检测血清心肌损害标志物,包括天冬氨酸转氨酶(AST)、肌酸激酶、肌酸激酶同工酶(CK—MB)、乳酸脱氢酶(LDH)及肌钙蛋白I。比较组间及治疗前后心肌损害标志物水平的变化。结果213例患儿血清中AST、肌酸激酶、CK—MB、LDH及肌钙蛋白I升高例数及比例分别为208例(97.7%)、90例(42.3%)、206例(96.7%)、187例(87.8%)、51例(23.9%)。败血症组患儿血清AST、CK—MB及LDH水平高于肺炎组,差异有统计学意义[(93±11)U/L比(67±4)U/L、(39.5±5.3)μg/L比(28.3±1.9)μg/L、(701±39)U/L比(607±19)U/L](P〈0.01或P〈0.05),而2组间肌酸激酶、肌钙蛋白I水平差异无统计学意义(P〉0.05)。剖宫产组患儿血清LDH水平低于自然分娩组,差异有统计学意义[(581±25)U/L比(670±33)U/L](P〈0.05),而2组间AST、肌酸激酶、CK—MB及肌钙蛋白I水平差异无统计学意义(P〉0.05)。治疗7d后收集到112例患儿血样,AST、肌酸激酶、CK-MB及LDH水平低于治疗前,差异有统计学意义[(39.6±2.3)U/L比(78.7±4.7)U/L、(388±41)U/L比(1311±99)U/L、(15.1±2.5)μg/L比(38.6±2.8)μg/L、(425±15)U/L比(671±26)U/L](P〈0.01),而肌钙蛋白I水平与治疗前比较差异无统计学意义(P〉0.05)。结论新生儿感染性疾病可引起患儿心肌损害标志物水平升高,且心肌损害标志物水平与感染的严重程度有关。 Objective To analyze changes and clinical significance of myocardial damage markers in neonatal infectious disease. Methods A total of 213 neonates with infectious disease were enrolled in newborn ward of Beijing Anzhen hospital, Capital Medical University from January 2015 to June 2016, including 165 cases of neonatal pneumonia ( pneumonia group), 48 cases of septicemia ( septicemia group), 121 cases of natural childbirth( natural childbirth group), 92 cases of cesarean section (cesarean section group). Serum levels of aspartate aminotransferase(AST), creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH) and troponin I (cTnI) before and after 7 d of treatment were analyzed. Results Ratios of neonates with high serum levels of AST, CK, CK-MB, LDH, cTnI were 208 (97.7%), 90 (42. 3% ), 206 (96. 7% ), 187(87.8% ), 51 (23.9%), respectively. Serum levels of AST, CK-MB and LDH in septicemia group were significantly higher than those in pneumonia group[ (93 ± ll )U/L vs (67 ±4)U/L, (39. 5 ±5.3) μg/L vs (28. 3 ± 1.9)μg/L, (701 ±39) U/L vs (607 ± 19) U/L] (P 〈0.01 or P 〈0.05) ; CK and cTnI had no significant differences between groups(P 〉0. 05). The serum level of LDH in cesarean section group was significantly lower than that in natural childbirth group [ (581 ± 25 ) U/L vs (670 ± 33 ) U/L] ( P 〈 0. 05 ) ; AST, CK, CK-MB and eTnI had no significant differences between groups (P 〉 0. 05 ). Serum levels of AST, CK, CK-MB and LDH in 112 neonates after 7 d of treatment were significantly lower than those before treatment [ ( 39. 6 ± 2. 3 ) U/L vs (78.7±4.7)U/L, (388±41)U/Lvs (1 311±99)U/L, (15.1±2.5)μg/Lvs (38.6±2.8)μg/L, (425± 15 )U/L vs (671 ± 26)U/LI (P 〈 0. 01 ) ; cTnI there had no significant difference before and after treatment( P 〉 0. 05). Conclusion Neonatal infeetion can cause increased levels of myocardial damage markers, which is associated with severity of infection.
