In recent years, with the increase of antibiotic resistance, tigecycline has attracted much attention as a new broad-spectrum glycylcycline antibiotic. It is widely used in the treatment of complex skin and soft tissue infections, complex abdominal infections and hospital-acquired pneumonia by inhibiting bacterial protein synthesis. Tigecycline can exhibit significant time-dependent bactericidal activity, and its efficacy is closely related to pharmacokinetics. It can be evaluated by the ratio of AUC0-24 to the minimum inhibitory concentration (MIC) of pathogens. However, tigecycline may cause nausea, vomiting, diarrhea and a few patients have elevated serum aminotransferase, especially in critically ill patients. The safety of patients still needs further study.
In this study, the clinical data of 263 patients with pulmonary infection in Shengjing Hospital of China Medical University and the Second Affiliated Hospital of Dalian Medical University were collected retrospectively, and the hepatotoxicity prediction model was established. The potential correlation between the toxic and side effects of tigecycline and the number of hospitalization days was preliminarily discussed, and the correlation analysis between the number of hospitalization days and continuous variables was established. Finally, the deep learning model was used to predict the hospitalization days of patients through simulated blood drug concentration and clinical laboratory indicators.
The degree of abnormal liver function was significantly correlated with AST, GGT, MCHC and hospitalization days. Secondly, the correlation between hospitalization time and clinical test indexes and simulated drug concentration was analyzed. It was found that multiple clinical laboratory parameters of patients (such as EO #, HCT, HGB, MCHC, PCT, PLT, WBC, AST, ALT, Urea), first dose (Dose), age and APACHE II score were significantly correlated with hospitalization days. The simulated blood drug concentration was correlated with the length of hospital stay from 12 h after administration, and reached the strongest between 24 and 48 h. The AUC of the liver function prediction model can reach 0.90. Further analysis showed that there was a potential correlation between hepatotoxicity and hospitalization days. The median hospitalization days of patients in the non-hepatotoxicity group, liver function injury group and hepatotoxicity group were 20, 23, and 30 days, respectively. Based on these results, the length of hospital stay was predicted by the deep learning prediction model with an error within 1 day.
In this study, the hospitalization days of infected patients were predicted by deep learning model with low error. It was found that it was related to clinical test parameters, hepatotoxicity and dosage after administration. The results provided an important reference for the clinical application of tigecycline, and emphasized the need to pay attention to its toxic and side effects in use.
近年来,随着抗生素耐药性的增加,替加环素作为一种新型广谱甘氨酰环素类抗生素备受关注。它通过抑制细菌蛋白质合成,广泛用于治疗复杂皮肤及软组织感染、复杂腹腔感染和医院获得性肺炎。替加环素可表现出显著的时间依赖性杀菌活性,其疗效与药代动力学密切相关。可通过曲线下面积(AUC0-24)与病原体最低抑菌浓度(MIC)的比值进行评估。然而,替加环素可能会引起恶心、呕吐、腹泻,少数患者血清转氨酶升高,尤其是重症患者。患者的安全性仍需进一步研究。
本研究回顾性收集了中国医科大学附属盛京医院和大连医科大学附属第二医院263例肺部感染患者的临床资料,建立肝毒性预测模型。初步探讨替加环素毒副作用与住院天数之间的潜在相关性,并建立住院天数与连续变量的相关性分析。最后,利用深度学习模型通过模拟血药浓度和临床实验室指标预测患者的住院天数。
肝功能异常程度与谷草转氨酶(AST)、γ-谷氨酰转肽酶(GGT)、平均红细胞血红蛋白浓度(MCHC)及住院天数显著相关。其次,分析住院时间与临床检验指标及模拟药物浓度之间的相关性。发现患者的多个临床实验室参数(如嗜酸性粒细胞计数(EO#)、血细胞比容(HCT)、血红蛋白(HGB)、MCHC、降钙素原(PCT)、血小板计数(PLT)、白细胞计数(WBC)、AST、谷丙转氨酶(ALT)、尿素)、首剂剂量(Dose)、年龄及急性生理与慢性健康状况评分系统II(APACHE II)评分与住院天数显著相关。模拟血药浓度在给药后12小时与住院时间相关,在24至48小时之间相关性最强。肝功能预测模型的AUC可达0.90。进一步分析表明,肝毒性与住院天数之间存在潜在相关性。非肝毒性组、肝功能损伤组和肝毒性组患者的中位住院天数分别为20天、23天和30天。基于这些结果,利用深度学习预测模型预测住院天数,误差在1天以内。
本研究利用深度学习模型以较低误差预测了感染患者的住院天数。发现其与临床检验参数、肝毒性及给药后剂量有关。研究结果为替加环素的临床应用提供了重要参考,并强调在使用过程中需关注其毒副作用。
