| 1 | Management of hepatitis C in patients with chronic kidney disease显示文摘Hepatitis C virus(HCV) infection is highly prevalent among chronic kidney disease(CKD) subjects under hemodialysis and in kidney transplantation(KT) recipients, being an important cause of morbidity and mortality in these patients. The vast majority of HCV chronic infections in the hemodialysis setting are currently attributable to nosocomial transmission. Acute and chronic hepatitis C exhibits distinct clinical and laboratorial features, which can impact on managementand treatment decisions. In hemodialysis subjects, acute infections are usually asymptomatic and anicteric; since spontaneous viral clearance is very uncommon in this context, acute infections should be treated as soon as possible. In KT recipients, the occurrence of acute hepatitis C can have a more severe course, with a rapid progression of liver fibrosis. In these patients, it is recommended to use pegylated interferon(PEG-IFN) in combination with ribavirin, with doses adjusted according to estimated glomerular filtration rate. There is no evidence suggesting that chronic hepatitis C exhibits a more aggressive course in CKD subjects under conservative management. In these subjects, indication of treatment with PEG-IFN plus ribavirin relies on the CKD stage, rate of progression of renal dysfunction and the possibility of a preemptive transplant. HCV infection has been associated with both liver disease-related deaths and cardiovascular mortality in hemodialysis patients. Among those individuals, low HCV viral loads and the phenomenon of intermittent HCV viremia are often observed, and sequential HCV RNA monitoring is needed. Despite the poor tolerability and suboptimal efficacy of antiviral therapy in CKD patients, many patients can achieve sustained virological response, which improve patient and graft outcomes. Hepatitis C eradication before KT theoretically improves survival and reduces the occurrence of chronic graft nephropathy, de novo glomerulonephritis and post-transplant diabetes mellitus. | Roberto J Carvalho-Filho Ana Cristina CA Feldner Antonio Eduardo B Silva Maria Lucia G Ferraz | 2015 | World Journal of Gastroenterology2015，21，2： | 4 |
| 2 | Central nervous system vasculitis and polyneuropathy as first manifestations of hepatitis C显示文摘Sensory or motor peripheral neuropathy may be observed in a significant proportion of hepatitis C virus (HCV)-infected patients.However,central nervous system (CNS) involvement is uncommon,especially in cryoglobulin-negative subjects.We describe a case of peripheral neuropathy combined with an ischemic CNS event as primary manifestations of chronic HCV infection without cryoglobulinemia.Significant improvement was observed after antiviral therapy.We discuss the spectrum of neurological manifestations of HCV infection and review the literature. | Roberto J Carvalho-Filho Janaína Luz Narciso-Schiavon Luciano HL Tolentino Leonardo L Schiavon Maria Lucia G Ferraz Antonio Eduardo B Silva | 2012 | World Journal of Gastroenterology2012，18，2： | 3 |
| 3 | Prognostic impact of the Bismuth-Corlette classification:Higher rates of local unresectability in stageⅢb hilar cholangiocarcinoma显示文摘Background:The Bismuth-Corlette(BC)classification is used to categorize hilar cholangiocarcinoma by proximal extension along the biliary tree.As the right hepatic artery crosses just behind the left bile duct,we hypothesized that BCⅢb tumors would have a higher likelihood of local unresectability due to involvement of the contralateral artery.Methods:A retrospective review of a prospectively maintained database identified patients with hilar cholangiocarcinoma taken to the operating room for intended curative resection between April 2008 and September 2016.Cases were assigned BC stages based on preoperative imaging.Results:Sixty-eight patients were included in the study.All underwent staging laparoscopy after which 16 cases were aborted for metastatic disease.Of the remaining 52 cases,14 cases were explored and aborted for locally advanced disease.Thirty-eight underwent attempt at curative resection.After exclud-ing cases aborted for metastatic disease,the chance of proceeding with resection was 55.6%for BCⅢb staged lesions compared to 80.0%of BCⅢa lesions and to 82.4%for BCⅠ-Ⅲa staged lesions(P<0.05).About 44.4%of BCⅢb lesions were aborted for locally advanced disease versus 17.6%of remaining BC stages.Conclusions:When hilar cholangiocarcinoma is preoperatively staged as BCⅢb,surgeons should antici-pate higher rates of locally unresectable disease,likely involving the right hepatic artery. | Michael J Passeri Maria R Baimas-George Jesse K Sulzer David A Iannitti John B Martinie Erin H Baker Lee M Ocuin Dionisios Vrochides | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，2： | 3 |
| 4 | Quality 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 | 2019 | World Journal of Gastroenterology2019，25，38： | 2 |
| 5 | C-reactive protein and radiographic findings of lower respiratory tract infection in infants显示文摘AIM To evaluate the association between C-reactive protein(CRP) and radiological evidence of lower respiratory tract infection(LRTI) in infants.METHODS All patients aged less than 4 years who presented with suspected lower respiratory tract infection,who received a peri-presentation chest radiograph and CRP blood measurement over an 18-mo period were included in the study.Age,gender,source of referral,CRP,white cell count,neutrophil count along with the patients' symptoms and radiologist's report were recorded.RESULTS Three hundred and eleven patients met the inclusioncriteria.Abnormal chest radiographs were more common in patients with elevated CRP levels(P < 0.01).Radiologic signs of LRTI were identified in 73.7% of chest radiographs when a patient had a CRP level between 50-99 mg/L.CRP levels were a better predictor of positive chest radiograph findings for those aged greater than I year compared to those 1 year or less.CONCLUSION CRP may be used in patients with suspected LRTI diagnosis to select those who are likely to have positive findings on chest radiograph,thus reducing unnecessary chest radiographs. | Maria Twomey Hannah Fleming Fiachra Moloney Kevin P Murphy Lee Crush Siobhan B O’Neill Oisin Flanagan Karl James Conor Bogue Owen J O’Connor Michael M Maher | 2017 | World Journal of Radiology2017，9，4： | 2 |

| 18 | Neuroretinal hypoxic signaling in a new preclinical murine model for proliferative diabetic retinopathy显示文摘Diabetic retinopathy(DR)affects approximately one-third of diabetic patients and,if left untreated,progresses to proliferative DR(PDR)with associated vitreous hemorrhage,retinal detachment,iris neovascularization,glaucoma and irreversible blindness.In vitreous samples of human patients with PDR,we found elevated levels of hypoxia inducible factor 1 alpha(HIF1α).HIFs are transcription factors that promote hypoxia adaptation and have important functional roles in a wide range of ischemic and inflammatory diseases.To recreate the human PDR phenotype for a preclinical animal model,we generated a mouse with neuroretinal-specific loss of the von Hippel Lindau tumor suppressor protein,a protein that targets HIF1αfor ubiquitination.We found that the neuroretinal cells in these mice overexpressed HIF1αand developed severe,irreversible ischemic retinopathy that has features of human PDR.Rapid progression of retinopathy in these mutant mice should facilitate the evaluation of therapeutic agents for ischemic and inflammatory blinding disorders.In addition,this model system can be used to manipulate the modulation of the hypoxia signaling pathways,for the treatment of non-ocular ischemic and inflammatory disorders. | Katherine J Wert Vinit B Mahajan Lijuan Zhang Yuanqing Yan Yao Li Joaquin Tosi Chun Wei Hsu Takayuki Nagasaki Kerstin M Janisch Maria B Grant MaryAnn Mahajan Alexander G Bassuk Stephen H Tsang | 2016 | Signal Transduction and Targeted Therapy2016，1，1： | 1 |
