38例药物性肝损伤患者肝组织病理学特征分析

目的 探讨中西药和膳食补充剂相关的药物性肝损伤(DILI)患者肝组织病理学特点。方法 2017年1月1日～2020年12月31日上海中医药大学附属曙光医院诊治的DILI患者38例，均接受肝活检和结构化专家观点评估法(SEPO)评估，并验证药物性肝损伤组织病理学评分(DILI-PSS)的诊断价值。结果 38例DILI患者应用化学药品和生物制品14例(36.8%)、中草药12例(31.6%)、化学药品和生物制品合用中草药9例(23.7%)、膳食补充剂3例(7.9%);肝组织脂肪变性20例(52.6%),胆汁淤积22例(57.9%),胆管损伤15例(39.4%),嗜酸性粒细胞浸润11例(28.9%),肝细胞花环9例(23.7%),肉芽肿6例(15.8);少量坏死11例(28.9%),较多25例(65.8%),大量2例(5.3%);应用DILI-PSS诊断的AUROC为0.775 (95%CI:0.669～0.880,P<0.05),其灵敏度为81.6%,特异度为65.8%。结论 DILI患者肝组织有一定的病理学特征表现，应用DILI-PSS可能有助于诊断DILI,需要进一步研究。

Liver pathological features of patients with drug-induced liver injury: An analysis of 38 cases

Objective The aim of this study was to investigate the liver pathological features of patients with drug-induced liver injury(DILI). Methods Thirty-eight patients with DILI was encountered in our hospital between January 2017 and December 2020, and all were evaluated by structured expert opinion process(SEPO)and underwent liber biopsies. The diagnostic performance of DILI-pathological scroring system (DILI-PSS) was verified by the area under the receiver operating characteristic curve (AUROC). Results Out of the 38 patients with DILI, 14 patients (36.8%) had taken chemical medicines and biological products, 12 patients (31.6%) had taken Chinese herbal medicines, 9 patients (23.7%) had taken Chinese herbal, chemical medicines and biological products, and 3 patients (7.9%) had taken dietary supplements; the pathological examination showed that hepatic steatosis in 20 cases(52.6%), hepatic cholestasis in 22 cases(57.9%), bile duct damage in 15 cases(39.4%), eosinophil immersion in 11 cases(28.9%), hepatocellular wreaths in 9 cases (23.7%), and granuloma in 6 cases (15.8%); the AUROC was 0.775 with 95% confidence interval of 0.669-0.880 (P<0.05), and the sensitivity of 81.6% and the specificity of 65.8% when the DILI-pathological scroring system (DILI-PSS) was applied to predict the diagnosis. Conclusion The application of DILI-PSS might help diagnose patients with DILI, which needs further clinical investigation.
