| 1 | Assessment of drug-induced hepatotoxicity in clinical practice: A challenge for gastroenterologists显示文摘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. | Raúl J Andrade Mercedes Robles Alejandra Fernández-Castaer Susana López-Ortega M Carmen López-Vega M Isabel Lucena | 2007 | World Journal of Gastroenterology2007，13，3： | 18 |
| 2 | drug-induced autoimmune liver disease:a diagnostic dilemma of an increasingly reported disease显示文摘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 | Agustin Castiella Eva Zapata M Isabel Lucena Raúl J Andrade | 2014 | World Journal of Hepatology2014，6，4： | 13 |
| 3 | HER2 in gastric cancer: Comparative analysis of three different antibodies using whole-tissue sections and tissue microarrays显示文摘AIM:To compare the performance of three commercially available anti-human epidermalgrowth factor receptor 2(HER2)antibodies in whole-tissue sections and tissue microarrays(TMAs)of a series of gastric tumors.METHODS:We present a comparative analysis of three anti-HER2 antibodies(HercepTest,4B5 and SP3)using TMA and whole-tissue sections prepared from the same paraffin blocks of 199 gastric adenocarcinomas operated upon between January 2004 and December2008 at a Brazilian cancer hospital.The data on the patients’age,sex,the anatomical location of the tumor and the Lauren’s histological classification were collected from clinical and pathological records.The immunohistochemical(IHC)results were examined by two pathologists and the cases were classified as positive(3+),equivocal(2+)and negative(0 or 1+),according to the criteria of the IHC scoring system of gastric cancer.TMAs and whole-tissue sections were evaluated separately and independently.All cases yielding discordant IHC results and/or scored as 2+were subjected to dual-color in situ hybridization in order to determine the final HER2 status.Besides determining the sensitivity and predictive value for HER2-positive status,we measured the accuracy of each antibody by calculating the area under the receiver operating characteristic(ROC)curve.The agreement between the results obtained using the TMAs and those obtained using the whole-tissue sections was assessed by means of Kappa coefficient.RESULTS:Intratumoral heterogeneity of HER2 expression was observed with all antibodies.HER2-positive expression(3+)in the whole-tissue sections was observed in 23 cases(11.6%)using the 4B5 antibody,in 18 cases(9.1%)using the SP3 antibody and in 10 cases(5.1%)using the HercepTest antibody.In the TMAs,11 positive cases(5.6%)were identified using SP3 antibody,9(4.6%)using the 4B5 antibody and 6(3%)using the HercepTest antibody.The sensitivity using whole-tissue sections and TMA,respectively,was 95.2%and 42.9%with 4B5,90.5%and 66.7%with SP3 and 47.6%and42.9%with HercepTest.The accuracy,calculated from the area under the ROC curve,using whole-tissue sections and TMA,respectively,was 0.91 and 0.79 by 4B5,0.86 and 0.80 by SP3 and 0.73 and 0.71 by HercepTest.The concordance of the results obtained using wholetissue sections and TMA was 97.4%(Kappa 0.75)using HercepTest,85.6%(Kappa 0.56)using SP3 and 84.1%(Kappa 0.38)using 4B5.CONCLUSION:The use of the 4B5 antibody on wholetissue sections was the most accurate IHC method for evaluating HER2 expression in gastric adenocarcinoma. | Lucas Faria Abraho-Machado Alexandre Andrade dos Anjos Jácome Durval Renato Wohnrath José Sebastio dos Santos Estela Cristina Carneseca José Humberto Tavares Guerreiro Fregnani Cristovam Scapulatempo-Neto | 2013 | World Journal of Gastroenterology2013，19，38： | 12 |
| 4 | Concordance of non-invasive mechanical and serum tests for liver fibrosis evaluation in chronic hepatitis C显示文摘AIM To determine the sensitivity and specificity of liver stiffness measurement(LSM) and serum markers(SM) for liver fibrosis evaluation in chronic hepatitis C.METHODS Between 2012 and 2014,81 consecutive hepatitis C virus(HCV) patients had METAVIR score from liver biopsy compared with concurrent results from LSM [transient elastography(TE) [FibroS can~/ARFI technology(Virtual Touch~)] and SM [FIB-4/aspartate aminotransferase-toplatelet ratio index(APRI)].The diagnostic performance of these tests was assessed using receiver operating characteristic curves.The optimal cut-off levels of each test were chosen to define fibrosis stages F ≥ 2,F ≥ 3 and F = 4.The Kappa index set the concordance analysis.RESULTS Fifty point six percent were female and the median age was 51 years(30-78).Fifty-six patients(70%) weretreatment-na?ve.The optimal cut-off values for predicting F ≥ 2 stage fibrosis assessed by TE were 6.6 kP a,for acoustic radiation force impulse(ARFI) 1.22 m/s,for APRI 0.75 and for FIB-4 1.47.For F ≥ 3 TE was 8.9 kP a,ARFI was 1.48 m/s,APRI was 0.75,and FIB-4 was 2.For F = 4,TE was 12.2 kP a,ARFI was 1.77 m/s,APRI was 1.46,and FIB-4 was 3.91.The APRI could not distinguish between F2 and F3,P = 0.92.The negative predictive value for F = 4 for TE and ARFI was 100%.Kappa index values for F ≥ 3 METAVIR score for TE,ARFI and FIB-4 were 0.687,0.606 and 0.654,respectively.This demonstrates strong concordance between all three screening methods,and moderate to strong concordance between them and APRI(Kappa index = 0.507).CONCLUSION Given the costs and accessibility of LSM methods,and the similarity with the outcomes of SM,we suggest that FIB-4 as well as TE and ARFI may be useful indicators of the degree of liver fibrosis.This is of particular importance to developing countries. | Denise C Paranaguá-Vezozzo Adriana Andrade Daniel F C Mazo Vinicius Nunes Ana L Guedes Taisa G Ragazzo Renata Moutinho Lucas S Nacif Suzane K Ono Venancio A F Alves Flair J Carrilho | 2017 | World Journal of Hepatology2017，9，8： | 7 |

| 6 | How to manage inflammatory bowel disease during the COVID-19 pandemic:A guide for the practicing clinician显示文摘Managing inflammatory bowel disease(IBD)during the coronavirus disease 2019(COVID-19)pandemic has been a challenge faced by clinicians and their patients,especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2).The knowledge about the impact of this virus on patients with IBD,although it is still scarce,is rapidly evolving.In particular,concerns surrounding medications’impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19,and potentially exacerbate viral replication and the COVID-19 course,are a current thinking of both practicing clinicians and providers caring for patients with IBD.Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19.In this review,we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection,and the COVID-19 impact on both the patient's psychological functioning and endoscopy services,and we concisely summarize the telemedicine roles during the COVID-19 pandemic. | Júlio Maria Fonseca Chebli Natália Sousa Freitas Queiroz Adérson Omar Mourão Cintra Damião Liliana Andrade Chebli Márcia Henriques de Magalhães Costa Rogério Serafim Parra | 2021 | World Journal of Gastroenterology2021，27，11： | 2 |

| 8 | Personalized medicine in gastric cancer:Where are we andwhere are we going?显示文摘Despite improvements in adjuvant therapies for gastric cancer in recent years, the disease is characterized by high recurrence rates and a dismal prognosis. The major improvement in the treatment of recurrent or metastatic gastric cancer in recent years has been the incorporation of trastuzumab, a monoclonal antibody that inhibits human epidermal growth factor receptor 2(HER2) heterodimerization, after the demonstrated predictive value of the overexpression and/or amplification of this receptor. Beyond HER2, other genetic abnormalities have been identified, and these mutations may be targetable by tyrosine kinase inhibitors or monoclonal antibodies. The demonstration of four distinct molecular subtypes of gastric cancer by the Cancer Genome Atlas study highlight the enormous heterogeneity of the disease and its complex interplay between genetic and epigenetic alterations and provide a roadmap to implement genome-guided personalized therapy in gastric cancer. In the present review, we aim to discuss, from a clinical point of view, the genomic landscape of gastric cancer described in recent studies, the therapeutic insights derived from these findings, and the clinical trials that have been conducted and those in progress that take into account tailored therapies for gastric cancer. | Alexandre A Jácome Anelisa K Coutinho Enaldo M Lima Aline C Andrade JoséSebastião dos Santos | 2016 | World Journal of Gastroenterology2016，22，3： | 2 |
