Guidelines for the Diagnosis and Management of Herb-Induced Liver Injury

引用

Chinese Journal of Integrative Medicine 2018年第9期24卷 696-706页

作者： WANG jia-bo ZHU Yun BAI Zhao-fang WANG Fu-sheng LI Xiu-hui XIAO Xiao-he Integrative Medical Center 302 Military Hospital of China Research Center for Biological Therapy 302 Military Hospital of China Integrative Medical Center Beijing You An HospitalCapital Medical University

Herb-induced liver injury （HILl） is a type of adverse drug reactions related to using Chinese medicine （CM） or herbal medicine （HM）, and is now a growing segment of drug-induced liver injury （DILl） worldwide. Owing to the complicated compositions and miscellaneous risk factors associated with the clinical usage of CM or HM, it is more challenging to diagnose and manage HILl than DILl. In the present guideline issued by the China Association of Chinese Medicine （CACM）, the authors present an evidence chain-based workflow with 9 structured judgment criteria for diagnosing HILl. The 3 diagnostic ending points--suspected diagnosis, clinical diagnosis, and confirmed diagnosis--could be reached according to the length of the evidence chain acquired in the structured diagnostic workflow. Either identifying the species of CM or HM or excluding adulterations and toxin contaminants was strongly recommended to improve the level of evidence for a clinical diagnosis of HILl. In addition, the authors report that the improper use of CM, which violates the general law of CM theory, is one of the most important factors that contributes to HILl and should be avoided. By contrast, based on syndrome differentiation, some CM can also be used to treat HILl if used in accordance with the general law of CM theory. Therefore, 9 recommendations are put forward in this guideline.

Objective： To investigate the antipyretic mechanism of Herba Ephedrae （Eph）-Ramulus Cinnamomi （RC） herb pair on yeast-induced pyrexia in rats. Methods： Totally 30 qualified male SD rats were randomly assigned to the normal control （NC） group, the pyrexia model （model） group, the Eph, RC and Eph-RC treatment groups by a random digital table, 6 rats in each group. Each rat received a 20% aqueous suspension of yeast （10 mL/kg） except the NC group. The 3 treatment groups were administered 8.1, 5.4 and 13.5 g/kg Eph, RC and Eph-RC respectively at 5 and 12 h after yeast injection, the NC group and the model groups were administered equal volume of distilled water. Rectal temperatures were measured at 0, 6, 8, 10, 12, 15, 18, 24 and 30 h and urine was collected prior to yeast injection and at 6, 10, 18, 24, 30, and 36 h after yeast injection. Then urine metabolomic profiling by gas chromatography tandem mass spectrometry, coupled with multivariate statistical analysis and pattern recognition techniques were used to explore the antipyretic effects of Eph-RC. Partial least squares discriminate analysis was used to analyze the metabolomics dataset including classification and regression in metabolomics plot profiling. Results： Compared with the NC group, rectal temperatures were significantly higher in the model group （P〈0.01）, while 3 treatment groups decreased significantly compared with the model group （P〈0.05 or P〈0.01）. Rectal temperatures of Eph-RC-treated rats started to go down at 6 h, and markedly decreased at 8, 12, 15, 18 and 24 h （P〈0.05 or P〈0.01）, while those of the Eph and RC groups had decreased firstly at 8 h and were markedly lower at 12 h （P〈0.05 or P〈0.01）. Seventeen potential biomarkers related to pyrexia were confirmed and identified, including pyruvic acid, L-phenylalanine, L-tyrosine, phenylacetic acid, hippuric acid, succinic acid, citrate and so on. Eight potential alterations of metabolic pathways including phenylalanine metabolism, citrate cycle, t

目的探索A型主动脉夹层(TAAD)术后急性心肌梗死(PAMI)患者的危险因素并构建模型,以预测此类患者PAMI的风险。方法回顾性分析2018年1月至2022年10月,就诊于北京安贞医院并接受外科手术治疗TAAD患者的临床资料。以PAMI为终点,随机将这些患者的70%划分为训练集,剩余30%的患者划分为验证集。在训练集中应用套索(LASSO)回归探寻危险因素,构建模型,绘制列线图,并在验证集中验证模型的区分度和校准度。结果本研究共纳入1206例患者,83例(6.9%)患者发生终点事件。LASSO回归分析表明冠脉灌注不良、凝血酶原时间、纤维蛋白原降解产物、淀粉酶、手术时间、心肺转流时间对TAAD PAMI有较高的重要度。根据预测因子构建出的模型在训练集中区分度良好,一致性指数(C-index)为0.843,且模型的准确度较高。模型在验证集中的C-index为0.845。在预测的主要终点事件发生风险低于50%的患者中,校准曲线表明预测风险和观测风险基本一致。结论本研究形成的TAAD患者PAMI预测模型具有良好的区分能力,有助于临床医生早期干预PAMI的发生发展,进而提高TAAD患者临床预后。
