Differences of clinical features and prognosis between Mycoplasma pneumoniae necrotizing pneumonia and non-Mycoplasma pneumoniae necrotizing pneumonia in children
Abstract Background In the past few years, Mycoplasma pneumoniae (Shi et al. Lancet 390:946–958, 2017) infection has been reported more in China. However, there are few studies on the clinical characteristics and prognosis of necrotizing pneumonia (NP) (Griffiths et al. Nature 583:615–619, 2020) caused by different pathogens. Methods A retrospective analysis was performed, including 31 children with a clinical diagnosis of NP in the hospital from January 1, 2013 to January 31, 2020. A total of 11 children with MPNP were included in the observation group and the other 20 children with other pathogens were included in the control group. The clinical manifestations, laboratory data, imaging findings, treatments and outcomes were analyzed. Results The proportion of dyspnea cases was significantly higher in the non-Mycoplasma pneumoniae necrotizing pneumonia (N-MPNP) group than that in the Mycoplasma pneumoniae necrotizing pneumonia (MPNP) group (P = 0.02).The LDH level of all patients in the MPNP group was higher than the normal value, with a median value of 805.0 U/L, which was significantly higher than those in the N-MPNP group (414.0 [299.9–540.6] U/L; Z = − 2.518; P = 0.012). The white blood cells (WBCs) count of the N-MPNP group was 17.8 (11.1–21.7) × 109/L, which was significantly higher than that of the MPNP group (10.2 [6.3–14.1] × 109/L; P < 0.05). The mean time of pulmonary necrosis in the MPNP group was 20.9 ± 6.9 days, which was higher than that of the N-MPNP group (16.8 ± 6.1 days; t = 3.101; P = 0.004). The incidence of pleural effusion in the N-MPNP group (19 patients, 95%) was significantly higher than that in the MPNP group (six patients, 54.55%) (P = 0.013). Among them, two patients received bronchoscopy lavage at a maximum four times, and the cases of plastic bronchitis were seen only in the MPNP group (3 cases; P = 0.037).The length of stay was 18 (10–22) days in the MPNP group and 23.5 (13.5–47) days in the N-MPNP group and no significant difference was observed between the two groups (Z = − 1.923, P = − 0.055). Conclusions 1. MP infection is the most common infection in children with NP in the Suzhou area. There is no gender and age difference between MPNP and N-MPNP, but the bacterial infection was mainly observed in the N-MPNP group. 2. Children in the N-MPNP group have more severe clinical symptoms, were more prone to shortness of breath, had a longer hospital stay, and had earlier imaging manifestations of necrosis, whereas children in the MPNP group were more likely to have plastic bronchitis. The level of WBC and LDH and the nature of pleural effusion can be used to identify MPNP and N-MPNP to some extent. 3. The prognosis of MPNP was better than that of N-MPNP. There were no death cases. Pleural thickening, pulmonary fibrosis, and bronchiectasis were the most common sequelae. Compared with N-MPNP, the recovery time of lung imaging in MPNP was shorter..
