摘要

La hepatotoxicidad inducida por medicamentos es un diagnóstico de descarte. Típicamente, se presenta en pacientes que desarrollan cambios clínicos y bioquímicos compatibles con hepatitis, pero relacionados con el inicio reciente de agentes farmacológicos, y que se resuelven tras el retiro de la noxa. Su desarrollo se ha descrito con el uso de algunos antibióticos, antituberculosos, estatinas, herbolarios y antiinflamatorios no esteroideos; sin embargo, hay pocos reportes de casos con el uso de anticonceptivos orales, en los cuales el surgimiento de mecanismos idiosincráticos puede llevar a la presentación de características clínicas como ictericia y anormalidades en los exámenes de laboratorio, como la elevación de las transaminasas. Esto requiere de estudios extensos para descartar otras patologías que pueden presentarse de esta forma, lo que representa un reto clínico. En este artículo se muestra el reporte de un caso de una paciente con antecedente de uso crónico de anticonceptivos implantables y que, tras el ajuste de la terapia con el inicio de anticonceptivos orales, desarrolla un episodio de elevación marcada de transaminasas e ictericia.


Drug-induced liver injury is a rule-out diagnosis. Typically, it occurs in patients who develop clinical and biochemical changes compatible with hepatitis, but related to a history of recent onset of pharmacological agents, and resolves after withdrawal of the noxious substances. Its development has been described with the use of some antibiotics, antituberculosis agents, statins, herbal and nonsteroidal anti inflammatory drugs; however, there are few reports of cases with the use of oral contraceptives, in which the appearance of idiosyncratic mechanisms can lead to the presentation of clinical features such as jaundice and laboratory tests abnormalities, like transaminase elevation, requiring extensive studies to rule out other pathologies that may have this clinical presentation, wich represents a clinical challenge. We present a case report of a patient who had chronic use of implantable contraceptives and who, after adjustment of therapy with the start of oral contraceptives, developed an episode of marked elevation of transaminases and jaundice.

摘要

Tanto la lesión hepática inducida por drogas (DILI), así como la lesión hepática inducida por hierbas (HILI), son una preocupación creciente en la atención sanitaria contemporánea que plantea importantes desafíos clínicos debido a sus variadas etiologías, presentaciones clínicas y posibles resultados potencialmente mortales. Presentamos el caso de un paciente masculino de 38 años con antecedentes de cálculos renales que consultó por dolor lumbar y hematuria. Al ingreso presentó ictericia, hepatomegalia, dolor a la palpación en fosa ilíaca derecha y no tenía signos de hepatopatía crónica, con pruebas de función hepática anormales, que mostraron un patrón hepatocelular asociado con hiperbilirrubinemia. Se descartó obstrucción biliar, trombosis portal, hepatitis autoinmune y viral, con panel autoinmune negativo. El paciente refirió haber consumido un remedio herbario para los cálculos renales llamado "vino rompe cálculos (chancapiedra)", que se supone contiene Phyllanthus niruri, cinco días antes del inicio de los síntomas. Una biopsia hepática reveló hepatitis aguda con infiltrado inflamatorio mixto. Debido al empeoramiento de las pruebas de función hepática y la sospecha de DILI idiosincrásico, se inició un ensayo terapéutico con corticosteroides, que resultó en una mejoría clínica y del perfil hepático. La gravedad de este caso nos recuerda la necesidad de incrementar el seguimiento por parte de las autoridades reguladoras de medicamentos, implementar campañas educativas para los pacientes e informar a la comunidad sobre productos con alertas activas.


Both drug-induced liver injury (DILI) and herb-induced liver injury (HILI) are a growing concern in contemporary healthcare that poses significant clinical challenges due to their varied etiology, clinical presentations, and potential life-threatening outcomes. We present the case of a 38-year-old male patient with a history of kidney stones who consulted for low back pain and hematuria. On admission he presented with jaundice, hepatomegaly, pain on palpation in the right iliac fossa and no signs of chronic liver disease, with abnormal liver function tests, which showed a hepatocellular pattern associated with hyperbilirubinemia. Biliary obstruction, portal thrombosis, autoimmune and viral hepatitis were ruled out, with negative autoimmune panel. The patient reported consuming an herbal remedy for kidney stones called "stone-breaking wine (chancapiedra)", presumed to contain Phyllanthus niruri, five days before the onset of symptoms. A liver biopsy revealedacute hepatitis with mixed inflammatory infiltrate. Due to worsening liver function tests and suspicion of idiosyncratic DILI, a therapeutic trial with corticosteroids was initiated, which resulted in clinical and liver profile improvement. The severity of this case reminds us of the need to increase follow-up by drug regulatory authorities, implement educational campaigns for patients, and inform the community about products with active alerts.

摘要

Objective To analyze the clinical characteristics of 310 patients with anti-tuberculosis drug-induced liver injury(ATB-DILI),to explore prognostic influencing factors,and to provide reference for its prevention and treatment.Methods Primary tuberculosis patients hospitalized in the Department of Tuberculosis of the Third People's Hospital of Kunming from November 2020 to November 2022 who met the diagnosis of ATB-DILI were enrolled.Statistics by gender,age,history,type of tuberculosis,co-morbidities,frequency of anti-tuberculosis regimens leading to liver injury,use of hepatoprotective drugs,and management and regression were performed to analyze the clinical characteristics of the patients and the factors influencing their prognosis.Results 310 patients were included,male,148(47.74%)and female,162(52.26%).The mean age was 44.33±17.47 years.Thirty-four patients had a history of allergy.The combination of isoniazid,rifampicin,pyrazinamide,and ethambutol(244 patients,78.71%)was the anti-tuberculosis regimen that resulted in the highest number of cases of hepatic injury.The median time between initiation of the tuberculosis regimen and the development of hepatic injury in patients with ATB-DILI was 30 d,and the mean duration of hospitalization was 16.39±7.01 d.The most used hepatoprotective drug was reduced glutathione(154 patients,49.68%),and most patients used a combination of 2 hepatoprotective drugs(128 patients,41.29%).Liver injury improved in 257 cases(82.90%)and failed in 53 cases(17.10%).The differences in alcohol consumption,severity,clinical staging,TT,ALP,TBIL,DBIL,IBIL,and GGT were statistically significant compared to those who did not recover(P<0.05),and severity and high ALP were independent risk factors for poor prognosis.Conclusions Patients should be carefully asked if they have a history of basic liver disease and alcoholism before using anti-tuberculosis drugs.In the course of anti-tuberculosis treatment,the combined use of anti-tuberculosis drugs is more serious than the use of single drugs to cause liver damage.Drugs that may cause liver damage should be used with caution and improved anti-tuberculosis programs should be explored.At the same time,liver function should be monitored regularly during anti-tuberculosis treatment,especially 30 days after medication,in order to reduce the occurrence of adverse reactions.

ObjectiveTo determine the scores of patients with a confirmed diagnosis of drug-induced liver injury (DILI) using Roussel Uclaf Causality Assessment Method (RUCAM), Maria & Victorino assessment scale, and Revised Electronic Causality Assessment Method (RECAM), to compare the accuracy of the three scales in diagnosis, and to investigate their clinical significance in the diagnosis of DILI. MethodsA total of 98 patients with a confirmed diagnosis of DILI who were hospitalized in Peking University First Hospital from January 2011 to December 2022 were enrolled, with liver biopsy results supporting DILI and a clear history of medication. Clinical data were collected from all subjects, and the above causality assessment scales were used for scoring. The chi-square test was used to analyze the diagnostic accuracy of the causality assessment scales, and the weighted kappa coefficient was used to analyze the consistency between the three scales. ResultsFor all patients with DILI enrolled, RECAM had the highest accuracy, with a significant difference compared with RUCAM (χ2=5.667,P=0.017). RUCAM and RECAM had moderate consistency in diagnosis (κw=0.469), while RECAM and Maria & Victorino scale had poor consistency (κw=0.156). For the patients with acute DILI, RECAM, RUCAM, and Maria & Victorino scales had a diagnostic inconsistency rate of 3.7%, 11.1%, and 42.6%, respectively; for the patients with hepatocellular type DILI, the three scales of a diagnostic inconsistency rate of 8.9%, 21.4%, and 62.5%, respectively; for the patients with cholestasis type or mixed type DILI, the three scales of a diagnostic inconsistency rate of 10.0%, 22.5%, and 47.5%, respectively. ConclusionThe use of RECAM and RUCAM scales in acute DILI can improve diagnostic rate, and for hepatocellular type DILI and DILI with the clinical manifestation of cholestasis (cholestasis type DILI and mixed type DILI), the use of RECAM and RUCAM scales can also improve diagnostic rate. The selection of causality assessment scales with a relatively high accuracy based on the course and clinical classification of the disease may help to further improve clinical diagnostic rate.

摘要

Caveolin-1 (CAV1) is a structural protein of caveolae on the plasma membrane and is an important regulatory factor for liver function. CAV1 regulates hepatic lipid deposition, lipid and glucose metabolism, mitochondrial function, and hepatocyte proliferation through various molecular pathways. Therefore, CAV1 plays a crucial role in maintaining liver physiology during the metabolic regulatory processes such as hepatic steatosis and hepatocyte proliferation. Furthermore, CAV1 is also involved in the development and progression of different types of liver injury, hepatitis, and liver cirrhosis. This article reviews the role of CAV1 in liver-related diseases and its mechanism in the regulation of liver macrophages, so as to provide a theoretical basis for targeting CAV1 in the treatment of liver-related diseases.

摘要

Idiosyncratic drug-induced liver injury (IDILI) has long posed a challenging and pivotal concern in pharmaceutical research. The complex composition of traditional Chinese medicine (TCM) has introduced a bottleneck in current research, hindering the elucidation of the component basis associated with IDILI in TCM. Using Epimedii Folium (EF) and Psoraleae Fructus (PF) as illustrative examples, this study endeavors to establish an in vitro evaluation model, providing a high-throughput and preliminary assessment method for screening components related to TCM-induced IDILI. A TNF-α-mediated HepG2 susceptible model was first established in this study, with the focus on the index components present in EF and PF. The release of lactate dehydrogenase (LDH) in the cell supernatant served as the detection index. A concentration-toxicity response curve was constructed, and the hepatotoxic components of EF and PF were identified utilizing the synergistic toxicity index. The LDH results unveiled the hepatotoxic effects of bavachin, backuchiol, isobavachin, neobavaisoflavone, psoralidin, isobavachalcone, icarisid I, and icarisid II on both normal and susceptible cells, categorizing these 8 components as both direct hepatotoxicity components and idiosyncratic hepatotoxicity components. Bavachin and neobavaisoflavone exhibited no hepatotoxicity on normal cells but demonstrated significant effects on susceptible cells, designating them as potential idiosyncratic susceptible hepatotoxicity components. The study further delineated that 10 EF components and 3 PF components were direct immune-promoting hepatotoxicity components. Additionally, 14 idiosyncratic immune-promoting hepatotoxicity components were identified, encompassing 10 EF components and 4 PF components, with neobavaisoflavone, bavachinin, and isobavachin being potential idiosyncratic susceptible immune-promoting hepatotoxicity components. Synergistic toxicity index results indicated that 13 idiosyncratic immune-promoting hepatotoxicity components (except anhydroicaritin) combined with bavachin demonstrated synergistic hepatotoxicity on susceptible cells. Notably, 3 idiosyncratic susceptible immune-promoting hepatotoxicity components combined with bavachin exhibited synergistic hepatotoxicity, with neobavaisoflavone displaying the highest synergistic toxicity index and bavachinin the lowest. In summary, this methodology successfully screens hepatotoxic and immune-promoting hepatotoxic components in EF and PF, distinguishing the types of components inducing hepatotoxicity, evaluating the hepatotoxicity degree of each component, and elucidating the synergistic relationships among them. Importantly, these findings align with the characteristics of IDILI. The method provides an effective model tool for the fundamental research of TCM-related IDILI components.

摘要

ObjectiveTo investigate the influencing factors for the clinical outcome of patients with drug-induced liver injury (DILI), and to establish a nomogram prediction model for validation. MethodsA retrospective analysis was performed for the general information and laboratory data of 188 patients with DILI who were admitted to Heilongjiang Provincial Hospital Affiliated to Harbin Institute of Technology from January 2017 to December 2022, and according to their clinical outcome, they were divided into good outcome group with 146 patients and poor outcome group with 42 patients. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate Logistic regression analyses were used to investigate the independent influencing factors for the clinical outcome of DILI patients. R Studio 4.1.2 software was used to establish a nomogram model, and calibration curve, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) were used to perform internal validation. ResultsThe univariate Logistic regression analysis showed that liver biopsy for the diagnosis of DILI, platelet count, cholinesterase, albumin, prothrombin time activity, IgM, and IgG were associated with adverse outcomes in patients with DILI. The multivariate Logistic regression analysis showed that liver biopsy for the diagnosis of DILI (odds ratio [OR]=0.072, 95% confidence interval [CI]: 0.022‍ ‍—‍ ‍0.213, P<0.001), clinical classification (OR=0.463, 95%CI: 0.213‍ ‍—‍ ‍0.926, P=0.039), alanine aminotransferase (OR=0.999, 95%CI: 0.998‍ ‍—‍ ‍1.000, P=0.025), prothrombin time activity (OR=0.973, 95%CI: 0.952‍ ‍—‍ ‍0.993, P=0.011), and IgM (OR=1.456, 95%CI: 1.082‍ ‍—‍ ‍2.021, P=0.015) were independent influencing factors for clinical outcome in patients with DILI. The nomogram prediction model was established, and after validation, the calibration curve was close to the reference curve. The area under the ROC curve was 0.829, and the DCA curve showed that the model had good net clinical benefit. ConclusionThe nomogram prediction model established in this study has good clinical calibration, discriminative ability, and application value in evaluating the clinical outcome of patients with DILI.

摘要

Pharmacotherapy is the primary treatment method for hyperthyroidism. Antithyroid drugs can induce liver injury, and the diagnosis of drug-induced liver injury is mostly exclusive based on medical history collection, clinical symptoms, serum biochemistry, radiological examination, and histology. According to the severity of liver injury, drug-induced liver injury can be classified into mild, moderate, severe, and fatal degrees. Drug withdrawal may not be necessary for patients with mild liver injury, but regular monitoring of liver function is required; in severe cases, patients may develop liver failure, which may lead to a mortality rate, and early identification, timely drug withdrawal, and reasonable pharmacotherapy can help to avoid fatal consequences. The treatment principles of liver injury induced by antithyroid drugs include promoting the recovery of liver injury, preventing the severe exacerbation and chronicity of liver injury, and reducing the risk of death. Standardized medication, timely monitoring, early identification, and early treatment are important measures for the prevention and treatment of liver injury induced by antithyroid drugs.

摘要

Polygonum multiflorum (PM), a commonly used Chinese herbal medicine in clinical practice, has been associated with frequent reports of liver injury in recent years, and the medication safety of PM has attracted more and more attention in China and globally. This article reviews the recent research advances in the signaling pathways and mechanisms of PM in causing drug-induced liver injury (DILI) and aims to provide new ideas for the proper and rational use of PM in clinical practice. The results show that PM is involved in the regulation of various signaling pathways, and it leads to the death of hepatocytes by destroying mitochondrial function, exacerbating bile acid accumulation, and inducing immune response, oxidative stress, and endoplasmic reticulum stress, thereby inducing the development and progression of DILI through multiple targets, pathways, and levels.

摘要

The incidence rate of drug-induced liver injury (DILI) is increasing year by year with unknown mechanisms, and the treatment methods for DILI mainly include drugs, liver support systems, and liver transplantation, all of which have certain limitations. Therefore, the search for safer and more effective treatment methods has become a research hotspot at present. Studies have shown that mesenchymal stem cells and their exosomes can alleviate liver injury by reducing liver inflammation, promoting hepatocyte proliferation and regeneration, inhibiting the apoptosis of hepatocytes, improving oxidative stress, and regulating immunity. This article briefly reviews the role of mesenchymal stem cells and their exosomes in the treatment of DILI, so as to provide a reference for further research.

摘要

Naproxen is a widely used nonsteroidal anti-inflammatory drug (NSAID) in pediatric population, used for mild-to-moderate pains, arthritis, and other immune-mediated disorders. It rarely causes clinically apparent liver injury in the adult population taking high doses of the drug over a prolonged period and is reported even rarer in pediatric population. We present a case of drug-induced liver injury (DILI) in a 13-year-old girl taking naproxen in therapeutic doses for juvenile rheumatoid arthritis. There was a complete recovery of liver function following discontinuation of naproxen therapy.

摘要

With the increase in the medical level, the improvement of adverse drug reaction(ADR) monitoring systems, and the enhancement of public awareness of safe medication, drug safety incidents have been frequently reported. Drug-induced liver injury(DILI), especially liver injury attributed to herbal and dietary supplements(HDS), has globally attracted high attention, bringing great threats and severe challenges to the people for drug safety management such as clinical medication and medical supervision. Consensus on drug-induced liver injury had been published by the Council for International Organizations of Medical Sciences(CIOMS) in 2020. In this consensus, liver injury attributed to HDS was included in a special chapter for the first time. The hot topics, including the definition of HDS-induced liver injury, epidemiological history, potential risk factors, collection of related risk signals, causality assessment, risk prevention, control and management were discussed from a global perspective. Based on the previous works, some experts from China were invited by CIOMS to undertake the compilation of this chapter. Meanwhile, a new causality assessment in DILI based on the integrated evidence chain(iEC) method was widely recognized by experts in China and abroad, and was recommended by this consensus. This paper briefly introduced the main contents, background, and characteristics of the Consensus on drug-induced liver injury. Significantly, a brief interpretation was illustrated to analyze the special highlights of Chapter 8, "Liver injury attributed to HDS", so as to provide practical references for the medical staff and the researchers who worked on either Chinese or Western medicine in China.

摘要

Gaining a better understanding of autoprotection against drug-induced liver injury(DILI)may provide new strategies for its prevention and therapy.However,little is known about the underlying mechanisms of this phenomenon.We used single-cell RNA sequencing to characterize the dynamics and functions of hepatic non-parenchymal cells(NPCs)in autoprotection against DILI,using acetaminophen(APAP)as a model drug.Autoprotection was modeled through pretreatment with a mildly hepatotoxic dose of APAP in mice,followed by a higher dose in a secondary challenge.NPC subsets and dynamic changes were identified in the APAP(hepatotoxicity-sensitive)and APAP-resistant(hepatotoxicity-resistant)groups.A chemokine(C-C motif)ligand 2+endothelial cell subset almost disappeared in the APAP-resistant group,and an R-spondin 3+endothelial cell subset promoted hepatocyte proliferation and played an important role in APAP autoprotection.Moreover,the dendritic cell subset DC-3 may protect the liver from APAP hepatotoxicity by inducing low reactivity and suppressing the autoimmune response and occurrence of inflammation.DC-3 cells also promoted angiogenesis through crosstalk with endothelial cells via vascular endothelial growth factor-associated ligand-receptor pairs and facilitated liver tissue repair in the APAP-resistant group.In addition,the natural killer cell subsets NK-3 and NK-4 and the Sca-1-CD62L+natural killer T cell subset may promote autoprotection through interferon-y-dependent pathways.Furthermore,macrophage and neutrophil subpopulations with anti-inflammatory phenotypes promoted tolerance to APAP hepatotoxicity.Overall,this study reveals the dynamics of NPCs in the resistance to APAP hepatotoxicity and provides novel insights into the mechanism of autoprotection against DILI at a high resolution.

ObjectiveTo explore and establish the liver injury risk prediction model of indirect toxicity of Chinese medicinals under the condition of compound formulas, and provide new ideas and methods for the study of evaluation of liver injury of Chinese medicinals based on indirect toxicity. MethodsTaking Buguzhi (Fructus Psoraleae) pre-parations as model drug, the combined Chinese medicinals with Buguzhi (Fructus Psoraleae) of high frequency are screened out, and their components and action targets were obtained through TCMSP, TCMIP and PharmMapper databases. The association strength value and risk value of Chinese medicinals that acted on the nuclear factor κB (NF-κB) pathway were analyzed. For those having greater values than the median association strength value and risk value were regarded as indirect Chinese medicinals of liver injury risk. In this way, a prediction model of liver injury risk of Chinese medicinals was constructed based on immune activation-related indirect liver injury process (taking NF-κB pathway as an example). And verification of the prediction model was performed using Heshouwu (Radix Polygoni Multiflori) preparations. ResultsThe prediction model of liver injury risk based on important immunoactivated pathway (taking NF-κB pathway as an example) found that Yinyanghuo (Herba Epimedii) (association strength value = 0.18, risk value = 0.25) was a Chinese medicinal with potential risk of indirect liver injury within Buguzhi (Fructus Psoraleae) prepartions, which may increase the risk of liver injury by positively regulating Bruton's tyrosine kinase (Btk) and protein kinase C theta (PKCθ) on NF-κB pathway. Further verification of prediction model by Heshouwu (Radix Polygoni Multiflori) preparations showed that Buguzhi (Fructus Psoraleae) (association strength value = 0.25, risk value = 0.33) and Tusizi (Semen Cuscutae) (Semen Cuscutae, association strength value = 0.34, risk value = 0.33) may increase the liver injury risk of Heshouzu. ConclusionThe liver injury risk prediction model of indirect toxicity of Chinese medicinals has been constructed in this study, providing metho-dological reference for the identification of Chinese medicinals of indirect liver injury risk under the condition of compound formulas.

摘要

Drug induced liver injury (DILI) refers to the liver injury caused by chemicals, biological products, traditional Chinese patent medicines and simple preparations and other drugs managed by prescription drugs or non prescription drugs, as well as Chinese medicinal materials, natural drugs, health products, dietary supplements and other products, or their metabolites and even their excipients, pollutants, impurities, etc. DILI is one of the most common Adverse drug reaction. In recent years, the incidence of DILI in China has increased year by year, posing a serious threat to the health of patients. The clinical manifestations of drug-induced liver injury are diverse, and the pathogenesis is complex, making diagnosis and prevention difficult. This article reviews the definition, epidemiology, clinical characteristics, and progress in diagnosis and treatment of DILI.
