| 1 | 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 |
| 2 | How important is donor age in liver transplantation?显示文摘The age of liver donors has been increasing in the past several years because of a donor shortage. In the United States, 33% of donors are age 50 years or older, as are more than 50% in some European countries. The impact of donor age on liver transplantation(LT) has been analyzed in several studies with contradictory conclusions. Nevertheless, recent analyses of the largest databases demonstrate that having an older donor is a risk factor for graft failure. Donor age is included as a risk factor in the more relevant graft survival scores, such as the Donor Risk Index, donor age and Model for End-stage Liver Disease, Survival Outcomes Following Liver Transplantation, and the Balance of Risk. The use of old donors is related to an increased rate of biliary complications and hepatitis C virus-related graft failure. Although liver function does not seem to be significantly affected by age, the incidence of several liver diseases increases with age, and the capacity of the liver to manage or overcome liver diseases or external injuries decreases. In this paper, the importance of age in LT outcomes, the role of donor age as a risk factor, and the influence of aging on liver regeneration are reviewed. | Alberto Lué Estela Solanas Pedro Baptista Sara Lorente Juan J Araiz Agustin Garcia-Gil M Trinidad Serrano | 2016 | World Journal of Gastroenterology2016，22，21： | 10 |
| 3 | Outcome in obscure gastrointestinal bleeding after capsule endoscopy显示文摘AIM: To investigate the clinical impact of capsule endoscopy(CE) after an obscure gastrointestinal bleeding(OGIB) episode, focusing on diagnostic work-up, followup and predictive factors of rebleeding. METHODS: Patients who were referred to Hospital del Mar(Barcelona, Spain) between 2007 and 2009 for OGIB who underwent a CE were retrospectively analyzed. Demographic data, current treatment with non-steroid antiinflammtory drugs or anticoagulant drugs, hemoglobin levels, transfusion requirements, previous diagnostic tests for the bleeding episode, as well as CE findings(significant or non-significant), work-up and patient out-comes were analyzed from electronic charts. Variables were compared by χ 2 analysis and Student t test. Risk factors of rebleeding were assessed by Log-rank test, Kaplan-Meier curves and Cox regression model. RESULTS: There were 105 patients [45.7% women, median age of 72 years old(interquartile range 56-79)] and a median follow-up of 326 d(interquartile range 123-641) included in this study. The overall diagnostic yield of CE was 58.1%(55.2% and 63.2%, for patients with occult OGIB and overt OGIB, respectively). In 73 patients(69.5%), OGIB was resolved. Multivariate analysis showed that hemoglobin levels lower than 8 g/dL at diagnosis [hazard ratios(HR) = 2.7, 95%CI: 1.9-6.3], patients aged 70 years and above(HR = 2.1, 95%CI: 1.2-6.1) and significant findings in CE(HR = 2.4, 95%CI: 1.1-5.8) were independent predictors of rebleeding. CONCLUSION: One third of the patients presented with rebleeding after CE; risk factors were hemoglobin levels < 8 g/dL, age ≥ 70 years or the presence of significant lesions. | Alex Caas-Ventura Lucia Márque Xavier Bessa Josep Maria DedeuDepartment of Gastroenterology Hospital del Mar Research Institute Pompeu Fabra University Marc Puigvehí Sílvia Delgado-Aros Ines Ana Ibáez Agustin Seoane Luis Barranco Felipe Bory Montserrat Andreu Begoa González-Suárez | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，11： | 4 |
| 4 | 对明串珠菌及其他细菌的抑制效果显示文摘在从压榨间直到蔗汁澄清的蔗糖生产过程中,蔗汁中微生物活动是破坏蔗糖品质的一个重要因素。蔗糖损失和葡聚糖的形成通常与蔗汁中微生物引起的变质有关。多年来,这一直成为糖厂试图改善蔗糖品质时所面临的问题。本文以直接影响得糖率的微生物减少和相对纯度为指标,研究了不同杀菌方法在蔗汁中的效果。浓度为0.007%的S抑制剂显示了对某糖厂初压汁和混合汁中的微生物菌群的抗菌效应。在对照组中,12h后观察到4.8单位的纯度降低。加入S抑制剂后,只降低2个单位。且蔗汁的稳定性在3个样品中几乎完全一致。以S抑制剂处理的蔗汁保持深褐色和清新的气味,且pH与初始相比无显著变化,而未处理的蔗汁变浅褐色,产生很强的酒味,pH和纯度显著降低。这种稳定效应尚未被其他常用的糖用杀菌剂所报导。同样,本文证明了有可能通过使用S抑制剂来稳定混合汁。经S抑制剂处理后,游离的还原物质和多聚糖比不经处理的样品低6倍。这些结果表明,形成的葡聚糖以及随之形成的游离果糖减少。 | Georgina Michelena Aidin Martinez Graciela Cerutti Monica Coronel Antonio Bell Emilia Carrera Agustin Lopez-Murguia Roberto Portuondo Lazaro Mergarejo Frost M Steele 李宜海 | 2006 | 广西轻工业2006，22，4： | 3 |
| 5 | Non-invasive methods for liver fi brosis prediction in hemochromatosis:One step beyond显示文摘Advances in recent years in the understanding of, and the genetic diagnosis of hereditary hemochromatosis (HH) have changed the approach to iron overload he-reditary diseases. The ability to use a radiologic tool (MRI) that accurately provides liver iron concentration determination, and the presence of non-invasive sero-logic markers for fibrosis prediction (ser um ferritin, platelet count, transaminases, etc), have diminished the need for liver biopsy for diagnosis and prognosis of this disease. Consequently, the role of liv er biopsy in iron metabolism disorders is changing. Furthermore, the irruption of transient elastography to assess liver stiffness, and, more recently, the ability to determine liver f ibrosis by means of MRI elastography will change this role even more, with a potential drastic decline in hepatic biopsies in years to come. This review will provide a brief summary of the different non-invasive methods available nowadays for diagnosis and prognosis in HH, and point out potential new techniques that could come about in the next years for fibrosis prediction, thus avoiding the need for liver biopsy in a greater number of patients. It is possible that liver biopsy will remain useful for the diagnosis of associated diseases, where other non-invasive means are not po-ssible, or for those rare cases displaying discrepancies between radiological and biochemical markers. | Agustin Castiella Eva Zapata José M Alústiza | 2010 | World Journal of Hepatology2010，2，7： | 3 |
