小儿肺炎支原体肺炎121例临床及X线分析

Clinical and X ray characteristics of mycoplasmal pneumonia in children

目的：探讨小儿肺炎支原体肺炎临床及Ｘ线特点。方法：采用日本富士明胶颗粒法测定小儿血清抗肺炎支原体抗体ＩｇＭ及胸部Ｘ线摄片。结果：确诊为支原体肺炎１２１例，临床表现主要有发热（４６．３％）、咳嗽（１００％），肺部体征少，胸片表现多种多样，包括：肺门阴影增大，间质浸润，支气管肺炎及叶／段实变。红霉素为治疗首选药物，有肺外合并症者加用糖皮质激素治疗有效。结论：小儿支原体肺炎咳嗽症状多，肺部体征少，胸片表现多种多样，认为肺炎支原体慢性感染及感染后免疫反应参与发病机理。

Objective:Clinical and X ray characteristics of mycoplasmal pneumonia in children were investigated. Methods:Serum anti mycoplasma pneumoniae IgM and plain X ray of the chest were examined. Results:The clinical features were mainly charaterized by fever (46.3%) and cough (100%),physical signs of the lungs were less commons including:hilus enlargement,interstitial pneumonia,bronchial pneumonia and lobar or segmental consolidation in X ray examination. Erythromycin was the drug of choice in treatment of the disease. Glucocorticoids were added in patients with extrapulmonary complications. Conclusions:Cough is the symptom most commonly seen with only few physical signs in mycoplasmal pneumonia,and chronic infection of mycoplasma pneumoniae and its postinfectional immunity play animportantroleinpathogenesisofthedisease.
