Clinical analysis of 84 cases of infants with pneumonia and mycoplasma pneumonia helps in identification. X-ray changes in infantile Mycoplasma pneumoniae (MP) pneumonia show diverse clinical manifestations and consistency; wheezing is indicated by chest X-ray performance showing interstitial infiltrates; prolonged fever duration, clinical symptoms, and chest X-ray segmental or lobar changes, or bilateral lesions, including pleural effusion in three cases and atelectasis in three cases. Moreover, the absorption of atelectasis in three cases took more than about two weeks. The optimal time window for MP-IgM detection is 7 to 10 days after onset; in this group of patients, 19 cases tested positive two weeks later, among which 12 cases were weakly positive, combined with positive agglutination to make the diagnosis. Studies suggest that this may be due to age and the children's small size, low immune response, late appearance of antibodies, and low titer-related issues. Recently, it has been reported that MP-I also appears in the early stages of infection, with better specificity compared to MP-I, and combining both improves diagnostic accuracy.
The patients were treated with erythromycin or azithromycin. The daily dose of erythromycin showed a good effect with mild gastrointestinal reactions, and children had good tolerability. Appropriate additives were given to reduce gastrointestinal side effects.
