摘要:

目的: 探讨结核病患者发生药物性肝损伤的危险因素,建立并验证列线图预测模型。方法: 回顾性收集2017年1月至2023年6月在镇江市第三人民医院接受抗结核治疗的498例结核病患者的临床资料,按照7:3的比例将患者分为建模组和验证组。通过LASSO回归、多因素logistic回归分析筛选影响因素,并建立列线图预测模型进行内外部验证。结果: 经LASSO筛选变量,多因素logistic回归分析结果显示,高血糖(OR=1.183,95%CI:1.037~1.349)、高血红蛋白(OR=1.028,95%CI:1.011~1.045)、合并肺外结核(OR=2.159,95%CI:1.240~3.759)和国际标准化比值高(OR=5.767,95%CI:1.259~26.421)是抗结核药物性肝损伤发生的危险因素,而尿酸水平高(OR=0.998,95%CI:0.996~0.999)和血小板水平高(OR=0.990,95%CI:0.986~0.995)是抗结核药物性肝损伤发生的保护因素。将上述变量构建列线图预测模型,建模组和验证组ROC曲线下面积分别为80.3%和79.1%;两组校准曲线的P值分别为0.318和0.605,预测值和实际值一致性较好;临床决策曲线阈值概率分别在9%~85%和1%~93%。结论: 本研究构建的预测模型具有较好的区分度、校准度和临床净获益,可为防控抗结核药物性肝损伤提供个体化依据。

Abstract:

Objective: To explore the risk factors of drug-induced liver injury in patients with tuberculosis, and to establish and validate a nomogram prediction model. Methods: The clinical data of 498 patients with anti-tuberculosis drug-induced liver injury (ATB-DILI) in the Third People’s Hospital of Zhenjiang from January 2017 to June 2023 were retrospectively collected. The patients were divided into modeling group and validation group according to the ratio of 7:3. The independent risk factors were screened using LASSO regression and multivariate logistic regression analysis, a nomogram prediction model was established for internal and external verification. Results: After LASSO screening variables, multivariate logistic regression analysis showed that hyperglycemia (OR=1.183, 95%CI: 1.037-1.349), high hemoglobin (OR=1.028, 95%CI: 1.011-1.045), extrapulmonary tuberculosis (OR=2.159, 95%CI: 1.240-3.759), and high international normalized ratio (OR=5.767, 95%CI: 1.259-26.421) were independent risk factors for ATLI, while high uric acid (OR=0.998, 95%CI: 0.996-0.999) and low PLT (OR=0.990, 95%CI: 0.986-0.995) were protective factors. The nomogram model was constructed based on the above related factors. The area under the receiver operating characteristic (ROC) curve was 80.3% and 79.1% in the modeling groups and validation groups, calibration curve P-value were 0.318 and 0.605, the decision curve showed that the nomogram model had certain clinical practicability in the high risk threshold range 9%-85% and 1%-93%. Conclusion: The nomogram model for risk predicting ATB-DILI among inpatients with tuberculosis in this study has good predictability, consistency and clinical practicability, which can provide individualized basis for the prevention and control of anti-tuberculosis drug-induced liver injury.
