-
摘要:
目的 检测ESAT-6联合IL-6、IL-10、IFN-γ、CK-18、MMP-7和MMP-9在抗结核药物性肝损伤(ATB-DILI)患者血清中的表达水平,分析上述指标与肝损伤严重程度的相关性,探讨7种因子对ATB-DILI的评估价值。 方法 纳入2019年1月至2023年1月就诊于昆明市第三人民医院的肺结核患者,使用ELISA方法检测210例ATB-DILI的肺结核患者(A组)、120例抗结核治疗未发生肝损伤的肺结核患者(B组)及50例健康体检者(C组)血清中的ESAT-6、IL-6、IL-10、IFN-γ、CK-18、MMP-7、MMP-9水平,分析上述指标与肝损伤严重程度的相关性,以及评估肝损伤严重程度的准确性。 结果 3组人群一般检查结果比较,A组患者年龄高于B、C组(P < 0.05)。与对照组比较,A组血清ESAT-6、IL-10、CK-18、MMP-7和MMP-9表达上调,B组ESAT-6和MMP-7表达上调(P < 0.05)。其中,A组CK-18、IL-10和MMP-9的表达量高于B组(P < 0.05)。A组的年龄、ESAT-6、CK-18和MMP-9与肝损伤严重程度呈正相关关系(P < 0.05)。Logistic回归分析显示,A组患者年龄>65岁、ESAT-6>31.3 pg/mL、CK-18>45.5 ng/mL是ATB-DILI的独立危险因素。 结论 高龄患者更易发生ATB-DILI,ESAT-6、CK-18和MMP-9升高与ATB-DILI严重程度有关。年龄>65岁、ESAT-6>31.3 pg/mL、CK-18>45.5 ng/mL是ATB-DILI的独立危险因素,联合检测高龄患者ESAT-6和CK-18表达水平,对预判及评估ATB-DILI严重程度具有较高的临床价值。 Abstract:Objective To detect the expression level of ESAT-6 combined with IL-6, IL-10, IFN-γ, CK-18, MMP-7, MMP-9 in the serum of patients with anti-tuberculosis drug induced liver injury (ATB-DILI), to analyze the correlation between the above indicators and the severity of liver injury, and to explore the evaluation value of 7 factors for ATB-DILI. Methods From January 2019 to January 2023, pulmonary tuberculosis patients treated at the Third People's Hospital of Kunming were included. Using the ELISA method, the levels of ESAT-6, IL-6, IL-10, IFN-γ, CK-18, MMP-7, and MMP-9 in the serum of 210 ATB-DILI tuberculosis patients (Group A), 120 tuberculosis patients without liver damage during anti-tuberculosis treatment (Group B), and 50 healthy individuals undergoing physical examinations (Group C) were tested. The correlation between the above indicators and the severity of liver damage was analyzed, as well as the accuracy of assessing the severity of liver damage. Results The age of patients in group A was higher than that in group B and C (P < 0.05). Compared with the control group, the expression of serum ESAT-6, IL-10, CK-18, MMP-7 and MMP-9 was significantly up-regulated in group A, and the expression of ESAT-6 and MMP-7 was significantly up-regulated in group B (P < 0.05). The expression levels of CK-18, IL-10, and MMP-9 in Group A were higher than in Group B (P < 0.05). In Group A, age, ESAT-6, CK-18, and MMP-9 were positively correlated with the severity of liver injury (P < 0.05). Logistic regression analysis indicated that age >65 years, ESAT-6 >31.3 pg/mL, and CK-18 >45.5 ng/mL in Group A patients were independent risk factors for ATB-DILI. Conclusion Elderly patients are more prone to ATB-DILI. Elevated levels of ESAT-6, CK-18, and MMP-9 are related to the severity of ATB-DILI. Age over 65, ESAT-6 > 31.3 pg/mL, and CK-18 > 45.5 ng/mL are independent risk factors for ATB-DILI. The combined detection of ESAT-6 and CK-18 expression levels in elderly patients holds significant clinical value for predicting and assessing the severity of ATB-DILI. -
