Objective:To study the effect of Yigan capsule on the expression of high mobility group protein B1(HMGB1),nuclear factor-B(NF-κB)and receptor for advanced glycation end products(RAGE)in anti-tuberculosis drug-induced liver injury(ATB-DILI),and to explore its protective effect and mechanism on ATB-DILI,so as to provide experimental basis for the clinical application of Yigan capsule.Methods:Twenty-four rats were divided into two groups.Except for the blank group(n=6),the other 18 rats were given isoniazid(INH)+rifampicin(RFP)(50 mg/kg.d)for 4 weeks.Then 18 rats were randomly divided into three groups(model group,low dose group of Yigan capsule and high dose group of Yigan capsule)according to 6 rats in each group.The blank group and the model group were given 0.9%sodium chloride solution by intragastric administration.The low dose group of Yigan capsule was 0.468 g/kg,and the high dose group of Yigan capsule was 1.872 g/kg[1].After 4 weeks,the pathological changes of liver were observed by HE staining.The contents of ALT,AST,ALP,γ-GT and TBIL were detected.The expression of HMGB1,NF-κBp65 and RAGE protein was detected by IHC.The expression levels of HMGB1,NF-κBp65,RAGE,TNF-αand IL-1βwere detected by WB.Result:HE staining showed that the structure of the liver in the model group was disordered,the liver cells showed swelling and fusion,the number of inflammatory cells increased and accompanied by punctate necrosis,while the above pathological changes in each treatment group of Yigan capsule were significantly improved.The contents of ALT,AST,ALP,γ-GT and TBIL in the model group were higher than those in the blank group(P<0.05).The contents of ALT,AST,ALP,γ-GT and TBIL in each treatment group were significantly lower than those in the model group(P<0.05).Compared with the blank group,the expression levels of TNF-αand IL-1βin the model group were increased(P<0.05),and the expression levels of HMGB1,NF-κBp65 and RAGE were increased(P<0.05).Compared with the model group,the expression levels of TNF-αand IL-1βin each treatment group of Yigan capsule decreased(P<0.05),and the expression of HMGB1,NF-κBp65 and RAGE decreased(P<0.05).Conclusion:Yigan capsule may inhibit the secretion of inflammatory factors through HMGB1/RAGE/NF-κBp65 signaling pathway,thus protecting ATB-DILI. 展开更多

Drug-induced liver injury(DILI)is caused by various drugs with complex pathogenesis,and diverse clinical and pathological phenotypes.Drugs damage the liver directly through drug hepatotoxicity,or indirectly through drug-mediated oxidative stress,immune injury and inflammatory insult,which eventually lead to hepatocyte necrosis.Recent studies have found that the composition,relative content and distribution of gut microbiota in patients and animal models of DILI have changed significantly.It has been confirmed that gut microbial dysbiosis brings about intestinal barrier destruction and microorganisms translocation,and the alteration of microbial metabolites may cause or aggravate DILI.In addition,antibiotics,probiotics,and fecal microbiota transplantation are all emerging as prospective therapeutic methods for DILI by regulating the gut microbiota.In this review,we discussed how the altered gut microbiota participates in DILI. 展开更多

BACKGROUND Interleukin-17(IL-17)inhibitors are known to cause exacerbation or new onset of inflammatory bowel disease upon administration.However,few reports have described characteristic endoscopic and histopathologic findings,and no small intestinal lesions have been reported so far.CASE SUMMARY A woman in her 60s with psoriasis was administered ixekizumab(IXE),an anti-IL-17A antibody,for the treatment of psoriasis.Twenty months after commencing treatment,the patient visited our hospital because of persistent diarrhea.Blood tests performed at the time of the visit revealed severe inflammation,and colonoscopy revealed multiple round ulcers throughout the colon.A tissue biopsy of the ulcer revealed infiltration of inflammatory cells and granuloma-like findings in the submucosal layer.Capsule endoscopy revealed multiple jejunal erosions.After the withdrawal of IXE,the symptoms gradually improved,and ulcer reduction and scarring of the colon were endoscopically confirmed.CONCLUSION To the best of our knowledge,17 reports have documented IL-17 inhibitorinduced entero-colitis with endoscopic images,endoscopic findings,and pathological characteristics,including the present case.Nine of these cases showed diffuse loss of vascular pattern,coarse mucosa/ulcer formation in the left colon,and endoscopic findings similar to those of ulcerative colitis.In the remaining eight cases,discontinuous erosions and ulcerations from the terminal ileum to the rectum were seen,with endoscopic findings similar to those of Crohn’s disease.In this case,the findings were confirmed by capsule endoscopy,which has not been previously reported. 展开更多

Background:Despite its widespread therapeutic use and effectiveness,the underlying pharmacologic mechanisms of Wendan decoction(WDD)and how it works to treat sudden deafness(SD)remain unclear.In this study,the pharmacological mechanisms of WDD underlying SD were analyzed using network pharmacology and molecular docking.Methods:The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)was employed to identify the active compounds and target genes of WDD,and genes associated with SD were screened on five databases.RGUI conducted Gene Ontology(GO)functional and the Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.A compound-target network was established using Cytoscape,and the STRING database created a protein-protein interaction(PPI)network to identify the key compounds and targets.Subsequently,a network of crucial compound-target was generated for further molecular docking analysis.For molecular docking simulations of the macromolecular target proteins and their matching ligand molecules,AutoDock Vina and AutoDockTool were utilized.Results:TCMSP identified 162 active target genes and 36 active compounds for WDD.The active target genes were compared with the 2271 genes associated with SD to identify 70 intersecting active target genes linked to 34 active compounds.The GO functional enrichment and KEGG pathway enrichment analyses were undertaken,and compound–target,and PPI networks were built.The key compounds and protein targets were identified and integrated to form a key compound–target network.Eventually,molecular docking was performed to investigate the interactions of the protein targets with their respective compounds.Conclusion:This study highlights the mechanisms of multi-compounds,targets,and pathways of WDD acting on SD and provides further evidence of crucial compounds and their matching target proteins of WDD acting on SD. 展开更多

BACKGROUND Empirical use of potentially hepatotoxic drugs in the management of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection is considered as one of the major etiopathogenetic factors for liver injury.Recent evidence has shown that an underlying genetic factor may also occur.Hence,it is important to understand the host genetics and iatrogenic-based mechanisms for liver dysfunction to make timely remedial measures.AIM To investigate drug-induced and genetic perspectives for the development of coronavirus disease 2019(COVID-19)-related liver injury.METHODS Reference Citation Analysis,PubMed,Google Scholar and China National Knowledge Infrastructure were searched by employing the relevant MeSH keywords and pertaining data of the duration,site and type of study,sample size with any subgroups and drug-induced liver injury outcome.Genetic aspects were extracted from the most current pertinent publications.RESULTS In all studies,the hepatic specific aminotransferase and other biochemical indices were more than their prescribed upper normal limit in COVID-19 patients and were found to be significantly related with the gravity of disease,hospital stay,number of COVID-19 treatment drugs and worse clinical outcomes.In addition,membrane bound O-acyltransferase domain containing 7 rs641738,rs11385942 G>GA at chromosome 3 gene cluster and rs657152 C>A at ABO blood locus was significantly associated with severity of livery injury in admitted SARS-CoV-2 patients.CONCLUSION Hepatic dysfunction in SARS-CoV-2 infection could be the result of individual drugs or due to drug-drug interactions and may be in a subset of patients with a geneticpropensity. Thus, serial estimation of hepatic indices in hospitalized SARS-CoV-2 patients shouldbe done to make timely corrective actions for iatrogenic causes to avoid clinical deterioration.Additional molecular and translational research is warranted in this regard. 展开更多

BACKGROUND A 70-year-old man with hepatitis C virus-related recurrent hepatocellular carcinoma was admitted for further diagnosis of a 1 cm iso-hyperechoic nodule in segment(S)5.CASE SUMMARY Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging(EOB-MRI)revealed the nodule in S5 with a defect at the hepatobiliary phase,hyperintensity on diffusion weighted imaging(DWI)and hypointensity on apparent diffusion coefficient(ADC)map.Contrast-enhanced computed tomography revealed hypervascularity at the early phase,and delayed contrast-enhancement was observed at the late phase.Contrast-enhanced ultrasound(US)revealed incomplete defect at the late vascular phase.Inflammatory liver tumor,lymphoproliferative disease,intrahepatic cholangiocarcinoma(small duct type)and bile duct adenoma were suspected through the imaging studies.US guided biopsy,however,showed a noncaseating hepatic sarcoid-like epithelioid granuloma(HSEG),and histopathological analysis disclosed spindle shaped epithelioid cells harboring Langhans-type multinucleated giant cells.One month after admission,EOB-MRI signaled the disappearance of the defect at the hepatobiliary phase,of hyperintensity on DWI,of hypointensity on ADC map,and no stain at the early phase.CONCLUSION That the patient had received BNT162b2 messenger RNA(mRNA)coronavirus disease 2019 vaccination 3 mo before the occurrence of HSEG,and that its disappearance was confirmed 4 mo after mRNA vaccination suggested that the drug-induced sarcoidosis-like reaction(DISR)might be induced by the mRNA vaccination.Fortunately,rechallenge of drug-induced DISR with the third mRNA vaccination was not confirmed. 展开更多

While mental health issues are increasingly gaining attention in Ghana, little is known about the situation among deaf people. This study assessed the mental health care needs of deaf people in Ghana. A descriptive design, consisting of interviews and focus group discussions, was used to collect data from 97 participants. Findings indicated that participants had limited knowledge on mental health issues. Mental health stigma, inaccessible mental health information and exclusion from mental health programmes were the major barriers hindering access to mental health care services. This study bridges the knowledge gap and provides evidence for the implementation of deaf-friendly services. 展开更多

The aetiology of autoimmune hepatitis(AIH) is uncer-tain but the disease can be triggered in susceptible patients by external factors such as viruses or drugs.AIH usually develops in individuals with a genetic back-ground mainly consisting of some risk alleles of the major histocompatibility complex(HLA).Many drugs have been linked to AIH phenotypes,which sometimes persist after drug discontinuation,suggesting that they awaken latent autoimmunity.At least three clini-cal scenarios have been proposed that refers to drug- induced autoimmune liver disease(DIAILD):AIH with drug-induced liver injury(DILI); drug induced-AIH(DI-AIH); and immune mediated DILI(IM-DILI).In addi-tion,there are instances showing mixed features of DI-AIH and IM-DILI,as well as DILI cases with positive autoantibodies.Histologically distinguishing DILI from AIH remains a challenge.Even more challenging is the differentiation of AIH from DI-AIH mainly relying in histological features; however,a detailed standard-ised histologic evaluation of large cohorts of AIH and DI-AIH patients would probably render more subtle features that could be of help in the differential diag-nosis between both entities.Growing information on the relationship of drugs and AIH is being available,being drugs like statins and biologic agents more fre-quently involved in cases of DIAILD.In addition,there is some evidence on the fact that patients diagnosed with DIAILD may have had a previous episode of hepa-totoxicity.Further collaborative studies in DIAILD will strengthen the knowledge and understanding of this intriguing and complex disorder which might represent different phenotypes across the spectrum of 展开更多

The spectrum of drug-induced liver injury (DILI) is both diverse and complex. The first step in diagnosis is a suspicion of DILl based on careful consideration of recent comprehensive reports on the disease. There are some situations in which the suspicion of DILI is particularly strong. Exclusion of other possible etiologies according to the pattern of liver injury is essential for the diagnosis. In patients with suspected DILl, diagnostic scales, such as the Councils for International Organizations of Medical Sciences/ Roussel Uclaf Causality Assessment Method (CIOMS/RUCAM) scale, may be helpful for the final diagnosis. Early management of DILl involves prompt withdrawal of the drug suspected of being responsible, according to serum levels of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin (T-Bil). However, as DILI patients may show resolution of liver injury without discontinuation of the drug, it should be carefully evaluated whether the suspected drug should be discontinued immediately with adequate consideration of the importance of the medication. 展开更多

The classic view on the pathogenesis of drug-induced liver injury is that the so-called parent compounds are made hepatotoxic by metabolism (formation of neosubstances that react abnormally), mainly by cytochromes P-450 (CYP), with further pathways, such as mitochondrial dysfunction and apoptosis, also playing a role. Risk factors for drug-induced liver injury include concomitant hepatic diseases, age and genetic polymorphisms of CYP. However, some susceptibility can today be predicted before drug administration, working on the common substrate, by phenotyping and genotyping studies and by taking in consideration patients' health status. Physicians should always think of this adverse effect in the absence of other clear hepatic disease. Ethical and legal problems towards operators in the health care system are always matters to consider. 展开更多

AIM: To investigate an association between N -acetyltransferase 2 (NAT2 )-haplotypes/diplotypes and adverse effects in Japanese pulmonary tuberculosis patients. METHODS: We studied 100 patients with pulmonary TB treated with anti-TB drugs including INH. The frequencies and distributions of single nucleotide polymorphisms, haplotypes, and diplotypes of NAT2 were determined by the PCR-restriction fragment length polymorphism method, and the results were compared between TB patients with and without adverse effect, using multivariate logistic regression analysis.RESULTS: Statistical analysis revealed that the frequency of a variant haplotype, NAT2*6A , was signifi cantly increased in TB patients with hepatotoxicity, compared with those without hepatotoxicity [P = 0.001, odds ratio (OR) = 3.535]. By contrast, the frequency of a wild-type (major) haplotype, "NAT2*4", was signif icantly lower in TB patients with hepatotoxicity than those without hepatotoxicity (P < 0.001, OR = 0.265). There was no association between NAT2-haplotypes and skin rash or eosinophilia. CONCLUSION: The present study shows that NAT2 is one of the determinants of anti-TB drug-induced hepatotoxicity. Moreover, the haplotypes, NAT2*4 and NAT2*6A, are useful new biomarkers for predicting anti- TB drug-induced hepatotoxicity. 展开更多

The diagnosi... Currently, pharmaceutical preparations are serious contributors to liver disease; hepatotoxicity ranking as the most frequent cause for acute liver failure and post-commercialization regulatory decisions. The diagnosis of hepatotoxicity remains a difficult task because of the lack of reliable markers for use in general clinical practice. To incriminate any given drug in an episode of liver dysfunction is a step-by-step process that requires a high degree of suspicion, compatible chronology, awareness of the drug’s hepatotoxic potential, the exclusion of alternative causes of liver damage and the ability to detect the presence of subtle data that favors a toxic etiology. This process is time-consuming and the final result is frequently inaccurate. Diagnostic algorithms may add consistency to the diagnostic process by translating the suspicion into a quantitative score. Such scales are useful since they provide a framework that emphasizes the features that merit attention in cases of suspected hepatic adverse reaction as well. Current efforts in collecting bona fide cases of drug-induced hepatotoxicity will make refinements of existing scales feasible. It is now relatively easy to accommodate relevant data within the scoring system and to delete low-impact items. Efforts should also be directed toward the development of an abridged instrument for use in evaluating suspected drug-induced hepatotoxicity at the very beginning of the diagnosis and treatment process when clinical decisions need to be made. The instrument chosen would enable a confident diagnosis to be made on admission of the patient and treatment to be fine-tuned as further information is collected. 展开更多

AIM: To analyze the outcome of patients with severe drug-induced liver disease (DILD) associated with jaundice classified as hepatocellular, cholestatic or mixed liver injury and to evaluate the validity of Hy’s rule and the most important predictors for outcome. METHODS: The Adverse Drug Reaction Advisory Committee was set up in 1997 in our hospital to identify all suspicions of DILD following a structured prospective report form. Liver damage was divided into hepatocellular, cholestatic, and mixed types according to laboratory and histologic criteria when available. Further evaluation of causality assessment was performed. RESULTS: From January 1997 to December 2004, 265 patients were diagnosed with DILD,and 140 (52.8%) of them were female. hepatocellular damage was the most common (72.1%), the incidence of death was 9.9% in patients with hepatocellular damage and 9.5% in patients with cholestatic/mixed damage (P < 0.05). There was no difference in age of dead and recovered patients. The proportion of females and males was similar in recovered and dead patients, no difference was observed in duration of treatment between the two groups. The serum total bilirubin (P < 0.001), direct bilirubin (P < 0.001) and aspartate transaminase (AST) (P = 0.013) values were higher in dead patients than in recovered patients. Chinese herbal medicine was the most frequently prescribed, accounting for 24.2% of the whole series. However, antitubercular drugs (3.4%) were found to be the primary etiological factor for fetal DILD. Factors associated with the development of fulminanthepatic failure were hepatic encephalopathy (OR = 43.66, 95% CI = 8.47-224.95, P < 0.0001), ascite (OR = 28.48, 95% CI = 9.26-87.58, P < 0.0001), jaundice (OR = 11.43, 95% CI = 1.52-85.96, P = 0.003), alcohol abuse (OR = 3.83, 95% CI = 1.26-11.67, P = 0.035) and direct bilirubin (OR = 1.93, 95% CI = 1.25-2.58, P = 0.012). CONCLUSION: Death occurs in 9.8% of patients with DILD. Chinese herbal medicine stands out as the most common drug for DILD. While antitubercular drugs are found to be the primary etiological factor for fetal DILD, hepatic encephalopathy, ascites, jaundice, alcohol abuse and direct bilirubin levels are associated with the death of DILD patients. 展开更多

DILI can be clinically divided into three phenotypes: hepatocytic, cholestatic and mixed. Although the clinical manifestations of DILI are variable and the pathogenesis complicated, recent insights using improved preclinical models, have allowed a better understanding of the mechanisms that trigger liver damage. In this review, we will discuss the pathophysiological mechanisms underlying DILI. The toxicity of the drug eventually induces hepatocellular damage through multiple molecular pathways, including direct hepatic toxicity and innate and adaptive immune responses. Drugs or their metabolites, such as the common analgesic, acetaminophen, can cause direct hepatic toxicity through accumulation of reactive oxygen species and mitochondrial dysfunction. The innate and adaptive immune responses play also a very important role in the occurrence of idiosyncratic DILI. Furthermore, we examine common forms of hepatocyte death and their association with the activation of specific signaling pathways. 展开更多

Drug-induced autoimmune hepatitis(DIAIH)is a specific phenotype of druginduced liver injury that may lead to the devastating outcome of acute liver failure requiring liver transplantation.Drugs implicated in DIAIH include antimicrobials such as nitrofurantoin and minocycline,non-steroidal anti-inflammatory drugs,statins as well as anti-tumor necrosis agents.The clinical features of druginduced liver injury are indistinguishable from idiopathic autoimmune hepatitis(AIH)as both may have positive AIH-related autoantibodies,elevated immunoglobulin G,as well as similar histopathological findings.In patients who show no clinical improvement,or there is progressive liver injury despite cessation of the suspected drug,a liver biopsy should be considered,whereby the presence of advance fibrosis on histology favors the diagnosis of idiopathic AIH.Empirical treatment with corticosteroids may be required in patients with non-resolving liver injury.A typical clinical scenario supportive of DIAIH includes a history of drug exposure with spontaneous resolution of liver injury after drug withdrawal and the absence of relapse after rapid steroid taper.In this article we report two cases of DIAIH secondary to Sorafenib and Atorvastatin along with a review of currently available literature.Early identification and treatment often lead to a favorable outcome in DIAIH. 展开更多

Although gallstone and alcohol use have been consid-ered the most common causes of acute pancreatitis, hundreds of frequently prescribed medications are as-sociated with this disease state. The true incidence is unknown since there are few population based studies available. The knowledge of drug induced acute pan-creatitis is limited by the availability and the quality of the evidence as the majority of data is extrapolated from case reports. Establishing a definitive causal rela-tionship between a drug and acute pancreatitis poses a challenge to clinicians. Several causative agent classifi-cation systems are often used to identify the suspected agents. They require regular updates since new drug induced acute pancreatitis cases are reported continu-ously. In addition, infrequently prescribed medications and herbal medications are often omitted. Furthermore, identification of drug induced acute pancreatitis with new medications often requires accumulation of post market case reports. The unrealistic expectation for a comprehensive list of medications and the multifacto-rial nature of acute pancreatitis call for a different ap-proach. In this article, we review the potential mecha-nisms of drug induced acute pancreatitis and providethe perspective of deductive reasoning in order to allow clinicians to identify potential drug induced acute pan-creatitis with limited data. 展开更多
