摘　　要：目的分析血清血管紧张素转换酶(sACE)水平、外周血CD_(4)+T淋巴细胞计数对肺结节病患者激素治疗反应及预后的预测价值。方法回顾性选取2017年1月至2022年3月郑州大学第一附属医院呼吸与危重症医学科收治的肺结节病患者91例为研究对象。收集患者的临床资料,采用多因素Logistic回归分析探讨肺结节病患者激素治疗反应及预后的影响因素,采用ROC曲线分析sACE水平、外周血CD_(4)+T淋巴细胞计数及其联合对肺结节病患者激素治疗反应及预后的预测价值。结果91例患者中,接受糖皮质激素治疗71例(激素治疗反应情况:敏感40例,不敏感31例),预后良好38例、预后不良53例。激素治疗反应敏感患者与激素治疗反应不敏感患者就诊时临床症状明显者占比、sACE水平、外周血CD_(4)+T淋巴细胞计数、外周血淋巴细胞绝对值、病变累及肺外实质器官者占比比较,差异有统计学意义(P<0.05)。预后良好患者与预后不良患者就诊时临床症状明显者占比、sACE水平、外周血CD_(4)+T淋巴细胞计数、外周血淋巴细胞绝对值、病变累及肺外实质器官者占比比较,差异有统计学意义(P<0.05)。多因素Logistic回归分析结果显示,sACE水平、外周血CD_(4)+T淋巴细胞计数是肺结节病患者激素治疗反应不敏感、预后不良的独立影响因素(P<0.05)。ROC曲线分析结果显示,sACE水平、外周血CD_(4)+T淋巴细胞计数及其联合预测肺结节病患者激素治疗反应不敏感的AUC分别为0.927〔95%CI(0.871,0.983)〕、0.882〔95%CI(0.783,0.981)〕、0.951〔95%CI(0.894,1.000)〕,最佳截断值分别为122.4 U/L、556个/μl、0.295,灵敏度分别为93.5%、96.2%、99.9%,特异度分别为80.0%、76.7%、83.3%;sACE水平、外周血CD_(4)+T淋巴细胞计数及其联合预测肺结节病患者预后不良的AUC分别为0.904〔95%CI(0.825,0.968)〕、0.898〔95%CI(0.820,0.976)〕、0.949〔95%CI(0.895,1.000)〕,最佳截断值分别为122Objective To analyze the predictive value of serum angiotensin converting enzyme(sACE)levels and peripheral blood CD_(4)+T lymphocyte count for hormone therapy response and prognosis in patients with pulmonary sarcoidosis.Methods A total of 91 patients with pulmonary sarcoidosis admitted to the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Zhengzhou University from January 2017 to March 2022 were retrospectively selected as the study objects.The clinical data of patients were collected,and the influencing factors of hormone therapy response and prognosis of patients with pulmonary sarcoidosis were investigated by multivariate Logistic regression analysis.The predictive value of sACE level,peripheral blood CD_(4)+T lymphocyte count and their combination on hormone therapy response and prognosis of patients with pulmonary sarcoidosis was analyzed by ROC curve.Results Among the 91 patients,71 received glucocorticoids(response to hormone therapy:40 were sensitive,31 were insensitive),38 had a good prognosis,and 53 had a poor prognosis.There were statistically significant differences in the proportion of patients with obvious clinical symptoms during medical treatment,sACE level,CD_(4)+T lymphocyte count in peripheral blood,absolute value of peripheral blood lymphocytes,and the proportion of patients with lesions involving parenchymal organs outside the lung between patients with sensitive response to hormone therapy and patients with insensitive response to hormone therapy(P<0.05).There were statistically significant differences in the proportion of patients with obvious clinical symptoms during medical treatment,sACE level,CD_(4)+T lymphocyte count in peripheral blood,absolute value of peripheral blood lymphocytes,and the proportion of patients with lesions involving parenchymal organs outside the lung between patients with good prognosis and patients with poor prognosis(P<0.05).Multivariate Logistic regression analysis showed that sACE level and CD_(4)+T lymphocyte count i
