| 1 | Characterization of hepatitis B virus X gene quasispecies complexity in mono-infection and hepatitis delta virus superinfection显示文摘Hepatitis delta virus(HDV) seems to strongly suppress hepatitis B virus(HBV)replication, although little is known about the mechanism of this interaction. Both these viruses show a dynamic distribution of mutants, resulting in viral quasispecies. Next-generation sequencing is a viable approach for analyzing the composition of these mutant spectra. As the regulatory hepatitis B X protein(HBx) is essential for HBV replication, determination of HBV X gene(HBX)quasispecies complexity in HBV/HDV infection compared to HBV monoinfection may provide information on the interactions between these two viruses.AIM To compare HBV quasispecies complexity in the HBX 5' region between chronic hepatitis delta(CHD) and chronic HBV mono-infected patients.METHODS Twenty-four untreated patients were included: 7/24(29.2%) with HBeAgnegative chronic HBV infection(CI, previously termed inactive carriers), 8/24(33.3%) with HBeAg-negative chronic hepatitis B(CHB) and 9/24(37.5%) with CHD. A serum sample from each patient was first tested for HBV DNA levels.The HBX 5' region [nucleotides(nt) 1255-1611] was then PCR-amplified for subsequent next-generation sequencing(MiSeq, Illumina, United States). HBV quasispecies complexity in the region analyzed was evaluated using incidencebased indices(number of haplotypes and number of mutations), abundancebased indices(Hill numbers of order 1 and 2), and functional indices(mutation frequency and nucleotide diversity). We also evaluated the pattern of nucleotide changes to investigate which of them could be the cause of the quasispecies complexity.RESULTS CHB patients showed higher median HBV-DNA levels [5.4 logIU/mL,interquartile range(IQR) 3.5-7.9] than CHD(3.4 logIU/mL, IQR 3-7.6)(P = n.s.)or CI(3.2 logIU/mL, IQR 2.3-3.5)(P < 0.01) patients. The incidence and abundance indices indicated that HBV quasispecies complexity was significantly greater in CI than CHB. A similar trend was observed in CHD patients, although only Hill numbers of order 2 showed statistically significant differences(CHB2.81, IQR 1.11-4.57 vs CHD 8.87, 6.56-11.18, P = 0.038). There were no significant differences in the functional indices, but CI and CHD patients also showed a trend towards greater complexity than CHB. No differences were found for any HBV quasispecies complexity indices between CHD and CI patients. G-to-A and C-to-T nucleotide changes, characteristic of APOBEC3 G, were higher in CHD and CI than in CHB in genotype A haplotypes, but not in genotype D. The proportion of nt G-to-A vs A-to-G changes and C-to-T vs T-to-C changes in genotype A and D haplotypes in CHD patients showed no significant differences. In CHB and CI the results of these comparisons were dependent on HBV genotype.CONCLUSION The lower-replication CHD and CI groups show a trend to higher quasispecies complexity than the higher-replication CHB group. The mechanisms associated with this greater complexity require elucidation. | Cristina Godoy David Tabernero Sara Sopena Josep Gregori Maria Francesca Cortese Carolina González Rosario Casillas Mar?al Yll Ariadna Rando Rosa López-Martínez Josep Quer Gloria González-Aseguinolaza Rafael Esteban Mar Riveiro-Barciela Maria Buti Francisco Rodríguez-Frías | 2019 | World Journal of Gastroenterology2019，25，13： | 6 |

| 3 | Analysis of hepatitis B virus preS1 variability and prevalence of the rs2296651 polymorphism in a Spanish population显示文摘AIM To determine the variability/conservation of the domain of hepatitis B virus(HBV) pre S1 region that interacts with sodium-taurocholate cotransporting polypeptide(hereafter, NTCP-interacting domain) and the prevalence of the rs2296651 polymorphism(S267 F, NTCP variant) in a Spanish population. METHODS Serum samples from 246 individuals were included and divided into 3 groups: patients with chronic HBV infection(CHB)(n = 41, 73% Caucasians), patients with resolved HBV infection(n = 100, 100% Caucasians) and an HBV-uninfected control group(n = 105, 100% Caucasians). Variability/conservation of the amino acid(aa) sequences of the NTCPinteracting domain,(aa 2-48 in viral genotype D) and a highly conserved pre S1 domain associated with virion morphogenesis(aa 92-103 in viral genotype D) were analyzed by next-generation sequencing and compared in 18 CHB patients with viremia > 4 log IU/mL. The rs2296651 polymorphism was determined in all individuals in all 3 groups using an in-house real-time PCR melting curve analysis.RESULTS The HBV pre S1 NTCP-interacting domain showed a high degree of conservation among the examined viral genomes especially between aa 9 and 21(in the genotype D consensus sequence). As compared with the virion morphogenesis domain, the NTCPinteracting domain had a smaller proportion of HBV genotype-unrelated changes comprising > 1% of the quasispecies(25.5% vs 31.8%), but a larger proportion of genotype-associated viral polymorphisms(34% vs 27.3%), according to consensus sequences from Gen Bank patterns of HBV genotypes A to H. Variation/conservation in both domains depended on viral genotype, with genotype C being the most highly conserved and genotype E the most variable(limited finding, only 2 genotype E included). Of note, proline residues were highly conserved in both domains, and serine residues showed changes only to threonine or tyrosine in the virion morphogenesis domain. The rs2296651 polymorphism was not detected in any participant.CONCLUSION In our CHB population, the NTCP-interacting domain was highly conserved, particularly the proline residues and essential amino acids related with the NTCP interaction, and the prevalence of rs2296651 was low/null. | Rosario Casillas David Tabernero Josep Gregori Irene Belmonte Maria Francesca Cortese Carolina González Mar Riveiro-Barciela Rosa Maria López Josep Quer Rafael Esteban Maria Buti Francisco Rodríguez-Frías | 2018 | World Journal of Gastroenterology2018，24，6： | 5 |
| 4 | Angiopoietin-2/angiopoietin-1 as non-invasive biomarker of cirrhosis in chronic hepatitis C显示文摘AIM To evaluate the efficacy of peripheral blood concentrations of angiopoietins(Ang) as cirrhosis biomarkers of chronic hepatitis C(CHC).METHODS Ang1 and Ang2 serum levels were measured by enzyme-linked immunosorbent assays(ELISA) in samples from 179 cirrhotic and non-cirrhotic CHC patients, classified according to the METAVIR system.Groups were compared by non-parametric MannWhitney U test. Subsequently, the association of peripheral concentrations of angiopoietins with the stage of fibrosis was analyzed using Spearman correlation test. Finally, the accuracy, sensitivity and specificity of circulating angiopoietins for cirrhosis diagnosis were determined by the study of the respective area under the curve of receiver operator characteristics(AUC-ROC).RESULTS Peripheral blood concentrations of Ang1 and Ang2 in CHC patients were significantly related to fibrosis. While Ang1 was decreased in cirrhotic subjects compared to non-cirrhotic(P < 0.0001), Ang2 was significantly increased as CHC progressed to the end stage of liver disease(P < 0.0001). Consequently, Ang2/Ang1 ratio was notably amplified and significantly correlated with fibrosis(P < 0.0001). Interestingly, the individual performance of each angiopoietin for the diagnosis of cirrhosis reached notable AUC-ROC values(above 0.7, both), but the Ang2/Ang1 ratio was much better(AUC-ROC = 0.810) and displayed outstanding values of sensitivity(71%), specificity(84%) and accuracy(82.1%) at the optimal cut-off(10.33). Furthermore, Ang2/Ang1 ratio improved the performance of many other previously described biomarkers or scores of liver cirrhosis in CHC.CONCLUSION Ang2/Ang1 ratio might constitute a useful tool for monitoring the progression of chronic liver disease towards cirrhosis and play an important role as therapeutic target. | ángel Hernández-Bartolomé Rosario López-Rodríguez María Jesús Borque Leticia González-Moreno Yolanda Real-Martínez Luisa García-Buey Ricardo Moreno-Otero Paloma Sanz-Cameno | 2016 | World Journal of Gastroenterology2016，22，44： | 4 |

| 6 | Use of agents stimulating erythropoiesis in digestive diseases显示文摘Anemia is the most common complication of inflammatory bowel disease (IBD). Control and inadequate treatment leads to a worse quality of life and increased morbidity and hospitalization. Blood loss, and to a lesser extent, malabsorption of iron are the main causes of iron def iciency in IBD. There is also a variable component of anemia related to chronic inflammation. The anemia of chronic renal failure has been treated for many years with recombinant human erythropoietin (rHuEPO), which significantly improves quality of life and survival. Subsequently, rHuEPO has been used progressively in other conditions that occur with anemia of chronic processes such as cancer, rheumatoid arthritis or IBD, and anemia associated with the treatment of hepatitis C virus. Erythropoietic agents complete the range of available therapeutic options for treatment of anemia associated with IBD, which begins by treating the basis of the inflammatory disease, along with intravenous iron therapy as f irst choice. In cases of resistance to treatment with iron, combined therapy with erythropoietic agents aims to achieve near-normal levels of hemoglobin/hematocrit (11-12 g/dL). New formulations of intravenous iron (iron carboxymaltose) and the new generation of erythropoietic agents (darbepoetin and continuous erythropoietin receptor activator) will allow better dosing with the same eff icacy and safety. | Rosario Moreno López Beatriz Sicilia Aladrén Fernando Gomollón García | 2009 | World Journal of Gastroenterology2009，15，37： | 2 |
| 7 | 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 |
