儿童难治性肺炎支原体肺炎的早期识别

Early identification of refractory Mycoplasma pneumoniae pneumonia in children

摘要:

目的 探讨早期识别儿童难治性肺炎支原体肺炎(RMPP)的临床指标,为早期干预治疗提供临床依据。方法 回顾性分析2014年1月至2015年6月诊断为肺炎支原体肺炎(MPP)的142例患儿的临床资料,其中RMPP患儿 32例,普通型MPP患儿110例,比较两组患儿临床指标的差异。结果 RMPP患儿发病年龄及学龄期儿童所占比例均高于普通型MPP患儿(P<0.05);有93.8%的RMPP患儿在治疗过程中使用激素,比例明显高于普通型MPP患儿(7.3%,P<0.001)。RMPP患儿胸片示以肺实变为主的大叶性肺炎表现为主,比例明显高于普通型MPP患儿(P<0.001),且胸腔积液发生率亦明显高于普通型MPP患儿(P<0.001)。RMPP组患儿C反应蛋白(CRP)>40 mg/L、血沉(ESR)>30 mm/h联合乳酸脱氢酶(LDH)>300 IU/L的发生概率明显高于普通型MPP患儿(P<0.05)。结论 RMPP患儿以学龄期儿童为主,影像学表现为肺实变的大叶性肺炎、有胸腔积液肺内并发症、CRP升高及ESR联合LDH同时增高对儿童RMPP的早期识别有一定临床意义。

Abstract:

Objective To investigate the clinical indicators for early identification of refractory Mycoplasma pneumoniae pneumonia (RMPP) in children. Methods The clinical data of 142 children with Mycoplasma pneumoniae pneumonia (MPP) between January 2014 and June 2015 were retrospectively studied. Among the 142 children, there were 32 cases of RMPP and 110 cases of non-refractory MPP. The clinical data were compared between the RMPP and non-refractory MPP groups. Results The percentage of school-age children in the RMPP group was higher than in the non-refractory MPP group (P<0.05). The mean onset age in the RMPP group was older than the non-refractory MPP group (P<0.05). Steroid was used in 93.8% of RMPP children compared with 7.3% of non-refractory MPP children (P<0.001). Consolidation of lung on chest X-Ray was shown in 87.5% of RMPP children compared with 42.7% of non-refractory MPP children (P<0.001). The incidence of pleural effusion in the RMPP group was higher than in the non-refractory MPP group (P<0.001). The RMPP group had higher percentages of individuals with CRP>40 mg/L and ESR>30 mm/h+LDH>300 IU/L than the non-refractory MPP group (P<0.05). Conclusions RMPP is common in school-age children. Consolidation of lung on chest X-Ray, pleural effusion and increased levels of CRP and ESR+LDH may be helpful to early identification of RMPP in children.
