目的
2
观察阿奇霉素治疗23S rRNA的A2063G基因位点突变肺炎支原体患儿的临床疗效。
方法
2
回顾性收集四川省妇幼保健院2023年1月至12月确诊的肺炎支原体肺炎(mycoplasma pneumoniae pneumonia,MPP)患儿并使用多重靶向扩增-高通量测序法(targeted next-generation sequencing,tNGS)检测出肺炎支原体的共242例。根据是否出现突变位点分为突变组(88例)和非突变组(154例)。
结果
2
88例患儿携带23S rRNA的A2063G位点突变基因;2组胸片均提示右侧病变多见于左肺。2组患儿均给予阿奇霉素治疗,2组患儿年龄、性别、发热时间、C-反应蛋白含量、胸部影像好转时间、用药天数、治疗有效率,比较差异无统计学意义(
P
>
0.05)。但呼吸道症状突变组比非突变组持续时间更长[(11.51±3.31) d vs. (10.06±3.63) d],差异有统计学意义(
P
<
0.05)。
结论
2
阿奇霉素对23S rRNA的A2063G基因位点突变肺炎支原体仍具有治疗作用。
Objective
2
To observe the clinical efficacy of azithromycin for the treatment of
Mycoplasma pneumoniae
pneumonia(MPP) with gene mutations at site A2063G of 23S rRNA in children.
Methods
2
Data were retrospectively collected for 242 children diagnosed with MPP at Sichuan Provincial Maternity and Child Health Care Hospital from January to December 2023,in whom MPP was detected using targeted next-generation sequencing(tNGS). According to the presence or absence of mutations,the children were classified into mutation group(88 cases) and non-mutation group(154 cases).
Results
2
Gene mutations at site A2063G of 23S rRNA were detected in 88 patients. The chest X-rays of both groups showed more lesions in the right lung than in the left lung. Both groups were treated with azithromycin and compared for differences in age,sex,duration of fever,C-reactive protein level,time to improvement of chest X-rays,days of medication,and response rate,with no significant differences found in the above indicators(
P
>
0.05). However,the duration of respiratory symptoms was significantly longer in the mutation group than in the non-mutation group [(11.51±3.31) d vs. (10.06±3.63) d,
P
<
0.05
]
.
Conclusion
2
Azithromycin is effective in treating MPP with gene mutations at site A2063G of 23S rRNA.
