Clinical Analysis of 417 Cases of Mycoplasma Pneumoniae Pneumonia Complicated by Extrapulmonary Complications / 天津医药

ABSTRACT

Objective To investigate the distribution, clinical diagnosis and treatment methods of the extrapulmo-nary complications in children with mycoplasma pneumoniae (MP). Methods The clinical data of 1 100 patients confirmed the diagnosis of mycoplasma pneumonia and with the positive serum MP-IgM test were collected in this study. The distribu-tion and clinical characteristics and MP-DNA detection rates were compared between 417 patients with extrapulmonary com-plications and 683 cases without complications. The occurrence of various complications in a four-year period was analyzed. Clinical data were compared between fiberoptic bronchoscopy lavage group and non-surgical group. Results The MP-DNA detection rate and the length of hospital stay were higher in patients with pulmonary complications than those of patients without complications. The most common types of extrapulmonary complications were liver damage, skin rashes and gastrointestinal reactions , but less severe. Encephalitis, nephritis and myocarditis were rare complications, but severe and occult. The fatal hemophagocytic lymphohistiocytosis (HLH) was also visible in patients. Bronchoscopy lavage was conducive to the recovery of the disease. Conclusion MP pneumonia showed high incidence and risks of extrapulmonary complica-tions, which required careful clinical observation and inspection, the dynamic monitoring laboratory markers and comprehen-sive treatment as well.
