Purpose To explore the dynamic changes in pulmonary and immune function among children with Mycoplasma pneumoniae pneumonia (MPP) and evaluate their value in disease severity stratification and prognosis prediction. Method A retrospective cohort of 225 pediatric patients with varying degrees of MPP severity and disease course was analyzed. Lung function and immunological indices were measured and compared across groups. Results Children with MPP exhibited significant impairments in pulmonary function and alterations in immune profiles compared to controls. These changes were associated with both disease severity and recovery status. Conclusion Pulmonary and immune function markers may serve as useful indicators for assessing severity and recovery in pediatric MPP. Their clinical application could improve individualized management strategies.
