4Monoclonal gammopathy of renal significance:Diagnostic workup显示文摘The clinical spectrum of diseases associated with monoclonal gammopathies is wide and they are most commonly the consequence of renal deposition of monoclonal immunoglobulin or its components. The differential diagnosis is difficult and renal biopsy is essential. To distinguish many of these pathologies is necessary to use techniques that are not always available, even in tertiary central hospitals. This review will discuss the clinical presentation, pathologic features, treatment, prognosis and common diagnostic difficulties of these entities.Sofia O Correia Sofia Santos Jorge Malheiro António Cabrita La Salete Martins Josefina Santos 2017World Journal of Nephrology2017,6,2:4
5Celiac disease serology in patients with different pretest probabilities: Is biopsy avoidable?显示文摘AIM: To establish the diagnostic performance of sev-eral serological tests, individually and in combination, for diagnosing celiac disease (CD) in patients with different pretest probabilities, and to explore potential se- rological algorithms to reduce the necessity for biopsy. METHODS: We prospectively performed duodenal biopsy and serology in 679 adults who had either high risk (n = 161) or low risk (n = 518) for CD. Blood samples were tested using six assays (enzyme-linked immunosorbent assay) that detected antibodies to tissue transglutaminase (tTG) and deamidated gliadin peptide (DGP). RESULTS: CD prevalence was 39.1% in the high-risk population and 3.3% in the low-risk group. In high-risk patients, all individual assays had a high diagnostic efficacy [area under receiving operator characteristic curves (AU ROC): 0.968 to 0.999]. In contrast, assays had a lower diagnostic efficacy (AU ROC: 0.835 to 0.972) in the low-risk group. Using assay combinations, it would be possible to reach or rule out diagnosis of CD without biopsy in 92% of cases in both pretest populations. We observed that the new DGP/tTG Screen assay resulted in a surplus compared to more conventional assays in any clinical situation. CONCLUSION: The DGP/tTG Screen assay could be considered as the best initial test for CD. Combinations of two tests, including a DGP/tTG Screen, might be able to diagnose CD accurately in different clinical scenarios making biopsy avoidable in a high proportion of subjects.Emilia Sugai María L Moreno Hui J Hwang Ana Cabanne Adriana Crivelli Fabio Nach-man Horacio Vázquez Sonia Niveloni Julio Argonz Roberto Mazure Graciela La Motta María E Caniggia Edgardo Smecuol Néstor Chopita Juan C Gómez Eduardo Maurińo Julio C Bai 2010World Journal of Gastroenterology2010,16,25:4

7慢性细菌性前列腺炎和肠易激综合征:利福昔明联合益生菌VSL#3的治疗效果显示文摘本研究评价了利福昔明联合益生菌VSL#3对慢性前列腺炎转化为微生物性前列腺精囊炎(PV)或前列腺精囊附睾炎(PVE)的作用。106例伴有细菌学治愈的慢性细胞性前列腺炎和肠易激综合征的男性不育患者随机予以利福昔明(200mg,20:/日,每月服用7日,持续12个月)和益生菌VSL#3(450×10^9CFU/日)治疗及无处理。95名患者(89.6%)完成治疗计划,纳入本研究。将患者分为四组:A组前6个月予治疗,后6月无治疗(n=26);B组予12个月治疗(n=22);C组前6个月不予治疗后6个月予治疗(n=23);D组在12个月内均无治疗(n=24)。A组和B组患者慢性前列腺炎发生率最高(分别为88.5%和86.4%)。相反,D组患者前列腺炎发生率最低(33.4%)。前列腺炎进展为PV的发生率在B组(15.5%)和C组(13.6%)低于D组(45.8%)。B组和C组最终无患者进展为PVE,而D组有20.8%诊断为PVE。长期服用利福昔明联合益生菌VSL#3能有效降低伴有治愈的CBP伴IBS的男性不育患者的前列腺炎进展为更复杂形式的男性附属性腺感染。Enzo Vicari Sandro La Vignera Roberto Castiglione Rosita A Condorelli Lucia O Vicari Aldo E Calogero 2014Asian Journal of Andrology2014,16,5:3
8Treatment of chronic hepatitis C with direct-acting antivirals: The role of resistance显示文摘The use of direct-acting antivirals(DAAs) to treat chronic hepatitis C has resulted in a significant increase in rates of sustained viral response(around 90%-95%) as compared with the standard treatment of peginterferon/ribavirin. Despite this, however, the rates of therapeutic failure in daily clinical practice range from 10%-15%. Most of these cases are due to the presence of resistant viral variants, resulting from mutations produced by substitutions of amino acids in the viral target protein that reduce viral sensitivity to DAAs, thus limiting the efficacy of these drugs. The high genetic diversity of hepatitis C virus has resulted in the existence of resistance-associated variants(RAVs), sometimes even before starting treatment with DAAs, though generally at low levels. These preexisting RAVs do not appear to impact on the sustained viral response, whereas those that appear after DAA therapy could well be determinant in virological failure with future treatments. As well as the presence of RAVs, virological failure to treatment with DAAs is generally associated with other factors related with a poor response, such as the degree of fibrosis, the response to previous therapy, the viral load or the viral genotype. Nonetheless, viral breakthrough and relapse can still occur in the absence of detectable RAVs and after the use of highly effective DAAs, so that the true clinical impact of the presence of RAVs in therapeutic failure remains to be determined.Miguel Jiménez-Pérez Rocío González-Grande Pilar Espana Contreras Isabel Pinazo Martínez Jesús de la Cruz Lombardo Raúl Olmedo Martín 2016World Journal of Gastroenterology2016,22,29:3
9Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari 2019World Journal of Gastroenterology2019,25,38:2
10Progress and challenges in the comprehensive management of chronic viral hepatitis: Key ways to achieve the elimination显示文摘Chronic viral hepatitis is a significant health problem throughout the world,which already represents high annual mortality.By 2040,chronic viral hepatitis due to virus B and virus C and their complications cirrhosis and hepatocellular carcinoma will be more deadly than malaria,vitellogenesis-inhibiting hormone,and tuberculosis altogether.In this review,we analyze the global impact of chronic viral hepatitis with a focus on the most vulnerable groups,the goals set by the World Health Organization for the year 2030,and the key points to achieve them,such as timely access to antiviral treatment of direct-acting antiviral,which represents the key to achieving hepatitis C virus elimination.Likewise,we review the strategies to prevent transmission and achieve control of hepatitis B virus.Finally,we address the impact that the coronavirus disease 2019 pandemic has had on implementing elimination strategies and the advantages of implementing telemedicine programs.Fátima Higuera-de la Tijera Alfredo Servín-Caamaño Luis Servín-Abad 2021World Journal of Gastroenterology2021,27,26:2
11西印度洋地区海草生态系统显示文摘海草是海洋被子植物,广泛分布在温带和热带的海岸带水域,是地球上水生生态系统中最具生产力的生物之一。在西印度洋地区大概有13种海草,这些海草覆盖了12000kg海岸线的近岸柔软海底广大区域。海草床一般分布在潮间带和潮下带,有时向下延伸至40m,并经常出现在珊瑚礁和红树林附近。由于具有很高的初级生产力和复杂的栖息环境,海草供养了许多底栖生物和浮游生物。许多鱼类和贝类,包括那些具有商业价值的种类都被吸引到海草栖息地,将海草作为其食物来源和避难场所,特别是在它们的幼年期。分布在西印度洋海草床附近广泛而丰富的鱼类资源就足以说明这一点。这些鱼分别属于天竺鲷科、亚科、玻甲鱼科、银鲈科、虾虎鱼科、隆头鱼科、裸颊鲷科、笛鲷科、单角亚科、鹦嘴鱼科、科、篮子鱼科、海龙科和Teraponidae科。因此,西印度洋地区的海草生态系统无论对当地还是整个地区的渔业发展都是非常有价值的资源。尽管如此,与其他地区相比,该地区有关海草资源的研究还十分缺乏,而且大多数研究也都集中在植物多样性和生态学上。本文主要阐述西印度洋地区海草床研究现状,特别强调鱼类和渔业。目前,该课题的大多数研究主要是在东非海岸开展的,如肯尼亚,坦桑尼亚,莫桑比克以及南非东部地区,而在索马里和西印度洋地区的岛屿国家(塞舌尔、科摩罗、法属留尼旺岛、毛里求斯、马达加斯加等)此类研究却很少,有关海草鱼类生态系统的论文也少有发表,而且大部分都是描述性的。因此,需要通过研究和实验获得有关描述模式和处理方法的科学知识。关于海草鱼类群落的定量研究,类似本文所介绍的案例研究在西印度洋地区是很少的,而这些研究对于渔业的管理前景而言是必不可少的。值得强调的是由于海岸人口的不断增长以及人类活动的侵扰给该地区海草床带来的压力与日俱增,如污染,海水富营养化,沉积作用,捕鱼以及无脊椎动物的采集等活动,而这些活动对于海草床的影响却鲜为人知。因此,需要开展广泛的研究,为西印度洋地区海草生态系统可持续管理提供有用的信息服务。Martin Gullstrm Maricela de la Torre Castro Salomo O.Bandeira Mats Bjrk Mattis Dahlberg Nils Kautsky Patrik Rnnbck Marcus C.hman 章任群 2002AMBIO-人类环境杂志2002,31,7:2
12策略将在肝移植以后减少丙肝病毒复发显示文摘 Hepatitis C virus (HCV) is a major health problem that leads to chronic hepatitis, cirrhosis and hepatocellular carcinoma, being the most frequent indication for liver transplantation in several countries. Unfortunately, HCV re-infects the liver graft almost invariably following reperfusion, with an accelerated history of recurrence, leading to 10%-30% of patients progressing to cirrhosis within 5 years of transplantation. In this sense, some groups have even advocated for not retransplanting this patients, as lower patient and graftoutcomes have been reported. However, the management of HCV recurrence is being optimized and several strategies to reduce post-transplant recurrence could improve outcomes, decrease the rate of re-transplantation and optimize the use of available grafts. Three moments may be the focus of potential actions in order to decrease the impact of viral recurrence: the pretransplant moment, the transplant environment and the post-transplant management. In the pre-transplant setting, it is not well established if reducing the pre transplant viral load affects the risk for HCV progression after transplant. Obviously, antiviral treatment can render the patient HCV RNA negative post transplant but the long-term benefit has not yet been fully established to justify the cost and clinical risk. In the transplant moment, factors as donor age, cold ischemia time, graft steatosis and ischemia/reperfusion injury may lead to a higher and more aggressive viral recurrence. After the transplant, discussion about immunosuppression and the moment to start the treatment (prophylactic, pre-emptive or once-confirmed) together with new antiviral drugs are of interest. This review aims to help clinicians have a global overview of posttransplant HCV recurrence and strategies to reduce its impact on our patients.Ruben Ciria María Pleguezuelo Shirin Elizabeth Khorsandi Diego Davila Abid Suddle Hector Vilca-Melendez Sebastian Rufian Manuel de la Mata Javier Briceo Pedro López Cillero Nigel Heaton 2013World Journal of Hepatology2013,5,5:2
13Involvement of serum retinoids and Leiden mutation in patients with esophageal, gastric, liver, pancreatic, and colorectal cancers in Hungary显示文摘AIM: To analyze the serum levels of retinoids and Leiden mutation in patients with esophageal, gastric, liver,pancreatic, and colorectal cancers.METHODS: The changes in serum levels of retinoids (vitamin A, α- and β-carotene, α- and β-cryptoxanthin,zeaxanthin, lutein) and Leiden mutation were measured by high liquid performance chromatography (HPLC)and polymerase chain reaction (PCR) in 107 patients (70 males/37 females) with esophageal (0/8), gastric (16/5), liver (8/7), pancreatic (6/4), and colorectal (30/21including 9 patients suffering from in situ colon cancer)cancer. Fifty-seven healthy subjects (in matched groups)for controls of serum retinoids and 600 healthy blood donors for Leiden mutation were used.RESULTS: The serum levels of vitamin A and zeaxanthin were decreased significantly in all groups of patients with gastrointestinal (GI) tumors except for vitamin A in patients with pancreatic cancer. No changes were obtained in the serum levels of α- and β-carotene,α- and β-cryptoxanthin, zeaxanthin, lutein in patients with GI cancer. The prevalence of Leiden mutation significantly increased in all groups of patients with GI cancer.CONCLUSION: Retinoids (as environmental factors)are decreased significantly with increased prevalence of Leiden mutation (as a genetic factor) in patients before the clinical manifestation of histologically different (planocellular and hepatocellular carcinoma, and adenocarcinoma) GI cancer.Gyula Mózsik Gy(o|¨)rgy Rumi András D(o|¨)m(o|¨)t(o|¨)r Mária Figler Beáta Gasztonyi El(?)d Papp Alajos Pár Gabriella Pár József Belágyi Zoltán Matus Béla Melegh 2005World Journal of Gastroenterology2005,11,48:2
