5. Conclusion
In conclusion, our study showes that MP is a significant pathogen of PB. The clinical manifestations of PB are not specific, children with PB might be easier to suffer from persistent fever, excessive inflammation and severe radiological findings. N% >75.5%, LDH >598.5U/L and D-dimer >0.45mg/L are important risk factors for multiple FOB procedures. Favorable prognosis can be expected with timely diagnosis and appropriate FOB treatment.
