目的
2
分析临床治疗有效的儿童肺炎支原体肺炎(MPP)伴肺实变的临床特征及影像学特点,随访患儿肺部CT的肺实变体积变化,探究肺实变吸收情况、预测肺实变完全吸收时间。
方法
2
纳入2018年1月至2024年5月于重庆医科大学附属儿童医院全科医学科住院的MPP伴肺实变病例。收集患儿住院期间的一般资料、临床症状、实验室指标、治疗情况、影像学数据以及出院后复查肺部CT数据、复查间隔时间,计算治疗前后肺实变体积、吸收率及吸收速率,对临床特征、影像学特点及肺实变吸收情况进行描述性统计分析。
结果
2
共纳入238例MPP伴肺实变患儿,女孩稍多于男孩(男女比例为109∶129),平均年龄在5岁左右,入院时咳嗽时间为7(5~9)d,发热时间为6(4~7) d;入院时白细胞、乳酸脱氢酶(LDH)升高不明显,超敏C-反应蛋白(hs-CRP)轻微升高;大部分患儿首选阿奇霉素治疗,近两年肺炎支原体耐药率增高,换用二线用药增多;行气管镜灌洗患儿占66.8%(159/238),未行气管镜灌洗占33.2%(79/238);肺实变部位单侧多于双侧(206例:32例),右侧多于左侧(117例:89例);肺实变占肺总体积比为4.48(2.61~7.35)%,复查时实变吸收率为96.08(88.02~98.95)%,复查间隔时间17(15~21) d,通过计算吸收速率2.15(1.23~4.01)cm
3
/d,实变完全吸收时间为18.96(16.14~23.33) d。
结论
2
临床治疗有效的儿童MPP肺实变间隔2~3周内复查肺CT,肺实变可基本吸收;通过计算肺实变初始体积,利用实变吸收速率,可推测出实变完全吸收时间,制定复查肺部CT最佳间隔时间。
Objective
2
To analyze the clinical characteristics and imaging features of e
ffectively treated pediatric
Mycoplasma pneumoniae
pneumonia (MPP) with pulmonary consolidation, follow up the volume changes of pulmonary consolidation on lung CT scans of the affected children, and investigate the resolution patterns of pulmonary consolidation, and predict the time required for complete resolution.
Methods
2
We enrolled children with MPP and pulmonary consolidation hospitalized in the Department of General Pediatrics at Children's Hospital of Chongqing Medical University between January 2018 and May 2024. Data collected included demographics, clinical symptoms, laboratory indicators, treatment status, imaging data during hospitalization, as well as follow-up lung CT data and reexamination intervals after discharge. Consolidation volumes were measured before and after the treatment to calculate the resolution rate and resolution velocity. Descriptive statistical analysis was performed on clinical characteristics, imaging features and consolidation resolution.
Results
2
Among 238 children with MPP and lung consolidation, females slightly outnumbered males (the male to female ratio is 109
vs
.129), with a mean age of approximately 5 years. At admission, the median cough and fever durations were 7 (5-9) days and 6 ( 4-7) days, respectively. No significant increase was found in white blood cells count or lactate dehydrogenase(LDH), and hypersensitive high-sensitivity C-reactive protein (CRP) slightly increased. Azithromycin was the first line of treatment in most cases, though second-line drugs increased in the recent two years due to the rising resistance. Bronchoalveolar lavage was performed in 66.8% (159/238) of children, and 33.2% (79/238) did not receive lavage. Consolidation was predominantly unilateral (206 unilateral
vs
. 32 bilateral) and right-sided (117 right-sided
vs
. 89 left-sided). The ratio of consolidation volume to total lung volume was 4.48 (2.61-7.35) %, the
consolidation resolution rate at follow-up was 96.08 ( 88.02-98.95) %, the reexamination interval was 17 ( 15-21) days, the resolution velocity was 2.15 (1.23-4.01) cm
3
/d, and the time to complete resolution was 18.96 (16.14-23.33) days .
Conclusions
2
Pulmonary consolidation in pediatric MPP achieves substantial resolution on CT within 2-3 weeks after effective clinical treatment. Initial consolidation volume and resolution velocity can predict the time required for complete resolution, thereby clinically guiding optimal CT follow-up scheduling.
