［摘 要］ 目的：基于简易危险分层探索血清可溶性生长刺激表达基因２（soluble growth stimulation expressed gene 2，sST2）蛋
白水平在评估结缔组织病相关肺动脉高压（connective tissue disease associated pulmonary arterial hypertension，CTD⁃PAH）病情
严重程度中的价值。方法：回顾性分析2017年1月—2021年11月在南京医科大学第一附属医院风湿免疫科由右心导管诊断
的48例CTD⁃PAH患者临床资料。收集患者基线及随访资料：血清sST2水平、人口统计学资料、原发病和PAH临床特征资料、
治疗方案。根据2018世界肺高压大会上发布的简易危险分层量表评估所有患者基线时危险分层水平。采用Pearson相关分
析和线性回归分析评价sST2水平与CTD⁃PAH临床基线资料之间的相关性；采用受试者工作特征（receiver operating characteris⁃
tics，ROC）曲线分析，确定基线sST2水平区分中高危CTD⁃PAH患者的最佳阈值。结果：中高危患者的血清sST2水平显著高于
低危患者［45.97（30.24，75.68）ng/mL vs. 29.36（20.89,41.25）ng/mL，P=0.006］。ROC 曲线分析提示 sST2≥45.56 ng/mL 可以识别
中高危CTD⁃PAH患者，灵敏度和特异度分别为56%和91%。结论：血清sST2水平与CTD⁃PAH患者病情严重程度相关，中高危
患者血清中sST2水平明显高于低危患者。sST2可作为CDT⁃PAH患者的预后生物标志物。

［Abstract］ Objective：The current study aims to explore the role of serum soluble growth stimulation expressed gene 2（sST2）in
evaluating the severity of connective tissue disease associated pulmonary arterial hypertension（CTD⁃PAH）based on simplified risk
stratification. Methods：A total of 48 patients with CTD⁃PAH diagnosed by right heart catheterization（RHC）were included from the
Departments of Rheumatology，the First Affiliated Hospital of Nanjing Medical University between Jan 2017 and Nov 2021. Baseline
clinical evaluation，laboratory index，RHC parameters and treatment regimen were collected. Pearson and analysis linear regression
were used for the correlation between clinical characteristics of CTD⁃PAH and sST2 level. A receiver operating characteristics（ROC）
curve assessed the diagnostic value of sST2 in assessing low risk and intermediate⁃high risk CTD⁃PAH patients. Results：CTD⁃PAH
patients in intermediate⁃high risk group was higher in sST2 level than low risk group［45.97（30.24，75.68）ng/mL vs. 29.36（20.89，
41.25）ng/mL，P=0.006］. ROC curve analysis showed that sST2≥45.56 ng/mL could identify intermediate⁃high risk CTD⁃PAH patients
with a sensitivity and specificity of 56% and 91%，respectively. Conclusion：The sST2 is significantly associated with parameters that
can reflect disease severity of CTD⁃PAH，and the sST2 level is signficantly higher in intermediate⁃high risk group than in low risk
group. The measurement of sST2 may serve as a prognostic biomarker of CTD⁃PAH patients.
