Abstract 【Objective】 To investigate the pulmonary function, inflammatory factors and clinical outcomes of children with refractory mycoplasma pneumoniae pneumonia (RMPP) and Mycoplasma pneumoniae pneumonia (MPP). 【Methods】A total of 110 children with MPP treated in our hospital from January 2019 to January 2022 were selected, of which 48 children with RMPP were included in the RMPP group and 62 children with common MPP were included in the MPP group. Levels of the pulmonary function indexes in acute stage and convalescent stage in terms of [first second forced expiratory volume (FEV₁), forced vital capacity (FVC), FEV₁/FVC], serum inflammatory factors [interleukin-2 (IL-2), interleukin-6(IL-6), tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ)] and abnormal lung function were compared between the two groups.【Results】FEV₁ and FVC in the recovery stage were higher than those in the acute stage (P<0.05), but there was no significant difference in FEV₁/FVC in the acute stage and the recovery stage between the two groups (P>0.05). The FEV₁ and FVC of the RMPP group in acute stage and recovery stage were lower than those of the MPP group (P<0.05). Serum levels of IL-2, IL-6, TNF-α and INF-γ in the recovery stage were lower than those in the acute stage (P<0.05). The serum levels of IL-2, IL-6, TNF-α and INF-γ in RMPP group were higher than those in the MPP group (P<0.05). There was no significant difference in the incidence of abnormal lung function between the two groups (P>0.05). The proportion of children with normal lung function in the RMPP group was lower than that in the MPP group, and the proportion of children with restrictive ventilation dysfunction was higher than that in the MPP group (P<0.05). 【Conclusion】Compared with children with MPP, children with RMPP have more severe lung function injury and inflammation. From the acute stage to the convalescent stage, both children with RMPP and MPP have improved lung function and reduced inflammation. However, children with RMPP have poor recovery and clinical outcomes, and a higher proportion of restricted ventilation dysfunction in convalescent stage.
