摘要 目的探讨肺部CT密度和血清半乳凝素9联合检测在评估老年隐源性机化性肺炎预后中的临床价值。方法选择老年隐源性机化性肺炎患者86例。随访13~24个月,将老年隐源性机化性肺炎根据预后评定预后转归进行分组,将缓解纳入预后良好组(n=70),将加重和死亡纳入预后不佳组(n=16)。检测两组的肺部CT密度及血清半乳凝素9的差异。探索基于CT密度及血清半乳凝素9指标在老年隐源性机化性肺炎转归预测模型,并初步评估其预测效率。结果与预后良好组相比,预后不佳组的年龄、肺CT密度和半乳凝素9均明显增高(P<0.05),肺CT密度及半乳凝素9评价隐源性机化性肺炎预后的临界值分别为85.4和25.4ng/L,ROC曲线下面积分别为0.741和0.851,两者联合检测的ROC曲线下面积为0.901,两者联合检测的灵敏度和特异度均高于单独检测。同时经Sperman分析显示,肺CT密度及半乳凝素9呈正相关关系(r=0.784,P=0.03)。结论肺部CT密度与血清半乳凝素9联合检测可用于评估老年隐源性机化性肺炎的预后。
