International guidelines including those in the UK, Japan, Australia and South Africa recommend the avoidance of macrolides in patients with low-severity community-acquired pneumonia (CAP). We hypothesised that severity scores are poor predictors of atypical pneumonia and response to macrolide therapy, and thus, inadequate tools for guiding antibiotic prescriptions. Secondary analysis of four independent prospective CAP datasets was conducted. The predictive values of the CURB-65 and pneumonia severity index (PSI) for clinically important groups of causative pathogens were evaluated. The effect of macrolide use according to risk class was assessed by multivariable analysis. Patients (3297) were evaluated, and the predictive values of CURB-65 and PSI for atypical pathogens were poor (AUC values of 0.37 and 0.42, respectively). No significant differences were noted among the effects of macrolide use on mortality in patients with mild, moderate and severe CAP, according to either CURB-65 (interaction testing severe versus mild disease OR=0.74 (0.29–1.89)) or PSI (severe versus mild disease OR=3.4 (0.055–2.10)), indicating that severity scores were not significant modifiers of response to macrolide therapy. Severity scores did not accurately predict response to macrolide therapy in CAP, suggesting that current guidance to use these tools for empirical antibiotic choices might not be justified.

社区获得性肺炎中大环内酯类药物使用的严重性评分指导方法评估

包括英国、日本、澳大利亚和南非在内的国际指南建议低严重度社区获得性肺炎 (CAP) 患者避免使用大环内酯类药物。我们假设严重度评分是非典型肺炎和大环内酯治疗反应的不良预测指标,因此,指导抗生素处方的工具不足。对四个独立的前瞻性 CAP 数据集进行了二次分析。评估了 CURB-65 和肺炎严重程度指数 (PSI) 对临床上重要的致病病原体组的预测值。根据风险等级使用大环内酯的效果通过多变量分析进行评估。对患者 (3297) 进行了评估,CURB-65 和 PSI 对非典型病原体的预测值较差(AUC 值分别为 0.37 和 0.42)。根据 CURB-65(重度与轻度疾病的相互作用测试 OR=0.74 (0.29–1.89))或 PSI(重度与轻度 CAP),大环内酯类药物使用对轻度、中度和重度 CAP 患者死亡率的影响没有显着差异。轻度疾病 OR=3.4 (0.055–2.10)),表明严重度评分不是对大环内酯治疗反应的显着调节因子。严重性评分不能准确预测 CAP 中大环内酯治疗的反应,这表明目前使用这些工具进行经验性抗生素选择的指导可能不合理。严重度评分不能准确预测社区获得性肺炎对大环内酯治疗的反应 http://ow.ly/IQjp30dRm7u 根据 CURB-65(重度与轻度疾病的交互测试 OR=0.74 (0.29–1.89))或 PSI(重度与轻度疾病 OR=3.4 (0.055–2.10)),表明严重度评分不是对大环内酯类疗法。严重性评分不能准确预测 CAP 中大环内酯治疗的反应,这表明目前使用这些工具进行经验性抗生素选择的指导可能不合理。严重度评分不能准确预测社区获得性肺炎对大环内酯治疗的反应 http://ow.ly/IQjp30dRm7u 根据 CURB-65(重度与轻度疾病的交互测试 OR=0.74 (0.29–1.89))或 PSI(重度与轻度疾病 OR=3.4 (0.055–2.10)),表明严重度评分不是对大环内酯类疗法。严重性评分不能准确预测 CAP 中大环内酯治疗的反应,这表明目前使用这些工具进行经验性抗生素选择的指导可能不合理。严重度评分不能准确预测社区获得性肺炎对大环内酯治疗的反应 http://ow.ly/IQjp30dRm7u 表明目前使用这些工具进行经验性抗生素选择的指导可能不合理。严重度评分不能准确预测社区获得性肺炎对大环内酯治疗的反应 http://ow.ly/IQjp30dRm7u 表明目前使用这些工具进行经验性抗生素选择的指导可能不合理。严重度评分不能准确预测社区获得性肺炎对大环内酯治疗的反应 http://ow.ly/IQjp30dRm7u
