| 1 | Vanishing bile duct syndrome in human immunodeficiency virus infected adults:A report of two cases显示文摘Vanishing bile duct syndrome(VBDS) is a group of rare disorders characterized by ductopenia,the progressive destruction and disappearance of intrahepatic bile ducts leading to cholestasis.Described in association with medications,autoimmune disorders,cancer,transplantation,and infections,the specific mechanisms of disease are not known.To date,only 4 cases of VBDS have been reported in human immunodeficiency virus(HIV) infected patients.We report 2 additional cases of HIV-associated VBDS and review the features common to the HIV-associated cases.Presentation includes hyperbilirubinemia,normal liver imaging,and negative viral and autoimmune hepatitis studies.In HIV-infected subjects,VBDS occurred at a range of CD4+ T-cell counts,in some cases following initiation or change in antiretroviral therapy.Lymphoma was associated with two cases;nevirapine,antibiotics,and viral co-infection were suggested as etiologies in the other cases.In HIV-positive patients with progressive cholestasis,early identification of VBDS and referral for transplantation may improve outcomes. | Ana Paula Oppenheimer Christopher Koh Mary McLaughlin John C Williamson Thomas D Norton Jennifer Laudadio Theo Heller David E Kleiner Kevin P High Caryn G Morse | 2013 | World Journal of Gastroenterology2013，19，1： | 8 |
| 2 | Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732). | Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco | 2012 | World Journal of Gastroenterology2012，18，26： | 6 |
| 3 | Presacral venous bleeding during mobilization in rectal cancer显示文摘AIM To analyze the anatomy of sacral venous plexus flow, the causes of injuries and the methods for controlling presacral hemorrhage during surgery for rectal cancer.METHODS A review of the databases MEDLINE? and Embase? was conducted, and relevant scientific articles published between January 1960 and June 2016 were examined. The anatomy of the sacrum and its venous plexus, as well as the factors that influence bleeding, the causes of this complication, and its surgical management were defined.RESULTS This is a review of 58 published articles on presacral venous plexus injury during the mobilization of the rectum and on techniques used to treat presacral venous bleeding. Due to the lack of cases published in the literature, there is no consensus on which is the best technique to use if there is presacral bleeding during mobilization in surgery for rectal cancer. This review may provide a tool to help surgeons make decisions regarding how to resolve this serious complication.CONCLUSION A series of alternative treatments are described; however, a conventional systematic review in which optimal treatment is identified could not be performed because few cases were analyzed in most publications. | Jose Enrique Casal Núnez Vincenzo Vigorita Alejandro Ruano Poblador Ana María Gay Fernández Maria ángeles Toscano Novella Nieves Cáceres Alvarado Lucinda Pérez Dominguez | 2017 | World Journal of Gastroenterology2017，23，9： | 4 |
| 4 | Thiopurine-methyltransferase variants in inflammatory bowel disease:Prevalence and toxicity in Brazilian patients显示文摘AIM:To analyze the prevalence of thiopurine-methyltransferase(TPMT)genotypes and their associationwith drug toxicity in inflammatory bowel disease(IBD)patients from southeastern Brazil.METHODS:A total of 219 consecutive patients with IBD,of which 146 had Crohn’s disease and 73 had ulcerative colitis,regularly seen at the outpatient unit of the Division of Gastroenterology at the University Hospital Pedro Ernesto of the State University of Rio de Janeiro,a tertiary referral center,were enrolled in this study from February 2009 to January 2011.We analyzed the presence of major TPMT genetic variants(TPMT*2,*3A,*3C)in IBD patients by means of a specific allele and RFLP-PCR.Genomic DNA was isolated from peripheral blood leukocytes by proteinase-K/Sodium Dodecyl Sulfate digestion and phenol-chloroform extraction.TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes were detected by real-time polymerase chain reaction followed by direct sequencing with specific primers.Clinical data were systematically recorded,and correlated with the genotype results.RESULTS:The distribution of the selected TPMT gene polymorphism TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes was 3.6%,5.4%,and 7.7%of the patients,respectively.Among the side effects recorded from patients taking azathioprine,14 patients presented with pancreatitis and/or an elevation of pancreatic enzymes,while 6 patients had liver toxicity,and 2 patients exhibited myelosuppression/neutropenia.TPMT polymorphisms were detected in 37/219 patients(8 heterozygous for*2,11 heterozygous for*3A,and 18 heterozygous for*3C).No homozygotic polymorphisms were found.Despite the prevalence of the TPMT*3C genotype,no differences among the genotype frequencies were significant.Although no association was detected regarding myelotoxicity or hepatotoxicity,a trend towards the elevation of pancreatic enzymes was observed for TPMT*2 and TPMT*3C genotypes.CONCLUSION:The prevalence of TPMT genotypes was high among Brazilian patients.Variants genes*2and*3C may be associated with azathioprine pancreatic toxicity in a IBD southeastern Brazilian population. | Ana Teresa P Carvalho Barbara C Esberard Renata S B Fróes Davy C M Rapozo Ana B Grinman Tatiana A Simo Juliana C V C Santos Antonio José V Carneiro Luis Felipe Ribeiro-Pinto Heitor S P de Souza | 2014 | World Journal of Gastroenterology2014，20，12： | 3 |
| 5 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018，24，38： | 3 |
| 6 | Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19. | Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral | 2021 | Cellular & Molecular Immunology2021，18，9： | 2 |

| 16 | Renal impairment and heart failure with preserved ejection fraction early post-myocardial infarction显示文摘AIM:To study if impaired renal function is associated with increased risk of peri-infarct heart failure (HF) in patients with preserved ejection fraction (EF).METHODS:Patients with occluded infarct-related arteries (IRAs) between 1 to 28 d after myocardial infarction (MI) were grouped into chronic kidney disease (CKD) stages based on estimated glomerular filtration rate (eGFR).Rates of early post-MI HF were compared among eGFR groups.Logistic regression was used to explore independent predictors of HF.RESULTS:Reduced eGFR was present in 71.1% of 2160 patients,with significant renal impairment (eGFR < 60 mL/min every 1.73 m2) in 14.8%.The prevalence of HF was higher with worsening renal function:15.5%,17.8% and 29.4% in patients with CKD stages 1,2 and 3 or 4,respectively (P < 0.0001),despite a small absolute difference in mean EF across eGFR groups:48.2 ± 10.0,47.9 ± 11.3 and 46.2 ± 12.1,respectively (P=0.02).The prevalence of HF was again higher with worsening renal function among patients with preserved EF:10.1%,13.6% and 23.6% (P < 0.0001),but this relationship was not significant among patients with depressed EF:27.1%,26.2% and 37.9% (P= 0.071).Moreover,eGFR was an independent correlate of HF in patients with preserved EF (P=0.003) but not in patients with depressed EF (P=0.181).CONCLUSION:A significant proportion of post-MI patients with occluded IRAs have impaired renal function.Impaired renal function was associated with an increased rate of early post-MI HF,the association being strongest in patients with preserved EF.These findings have implications for management of peri-infarct HF. | Vinod Jorapur Gervasio A Lamas Zygmunt P Sadowski Harmony R Reynolds Antonio C Carvalho Christopher E Buller James M Rankin Jean Renkin Philippe Gabriel Steg Harvey D White Carlos Vozzi Eduardo Balcells Michael Ragosta C Edwin Martin Vankeepuram S Srinivas William W Wharton III Staci Abramsky Ana C Mon Shari S Kronsberg Judith S Hochman | 2010 | World Journal of Cardiology2010，2，1： | 1 |
