2Gut microbiota role in irritable bowel syndrome:Newtherapeutic strategies显示文摘In the last decade the impressive expansion of our knowledge of the vast microbial community that resides in the human intestine, the gut microbiota, has provided support to the concept that a disturbed intestinal ecology might promote development and maintenance of symptoms in irritable bowel syndrome(IBS). As a correlate, manipulation of gut microbiota represents a new strategy for the treatment of this multifactorial disease. A number of attempts have been made to modulate the gut bacterial composition, following the idea that expansion of bacterial species considered as beneficial(Lactobacilli and Bifidobacteria) associated with the reduction of those considered harmful(Clostridium, Escherichia coli, Salmonella, Shigella and Pseudomonas) should attenuate IBS symptoms. In this conceptual framework, probiotics appear an attractive option in terms of both efficacy and safety, while prebiotics, synbiotics and antibiotics still need confirmation. Fecal transplant is an old treatment translated from the cure of intestinal infective pathologies that has recently gained a new life as therapeutic option for those patients with a disturbed gut ecosystem, but data on IBS are scanty and randomized, placebo-controlled studies are required.Eleonora Distrutti Lorenzo Monaldi Patrizia Ricci Stefano Fiorucci 2016World Journal of Gastroenterology2016,22,7:60
3Overview of hepatitis B virus mutations and theirimplications in the management of infection显示文摘Hepatitis B virus(HBV)affects approximately two billion people worldwide and more than 240 million people in the world are currently chronic carrier that could develop serious complications in the future,like liver cirrhosis and hepatocellular carcinoma.Although an extended HBV immunization program is being carried out since the early‘80s,representing effective preventive measure,leading to a dramatic reduction of HBV hepatitis incidence,globally HBV infection still represents a major public health problem.The HBV virus is a DNA virus belongs to the Hepadnaviridae family.The HBV-DNA is a circular,partial double strand genome.All coding information is on the minus DNA strand and it is organized into four open reading frames.Despite hepatitis B virus is a DNA virus,it has a high mutation rate due to its replicative strategy,that leads to the production of many nonidentical variants at each cycle of replication.In fact,it contains a polymerase without the proofreading activity,and uses an RNA intermediate(pg RNA)during its replication,so error frequencies are comparable to those seen in retroviruses and other RNA viruses rather than in more stable DNA viruses.Due to the low fidelity of the polymerase,the high replication rate and the overlapping reading frames,mutations occur throughout the genome and they have been identified both in the structural and not structural gene.The arise of mutations being to develop of a whole of viral variants called'quasi-species'and the prevalent population,which favors virus replication,was selected by viral fitness,host’s immune pressure and external pressure,i.e.,vaccination or antiviral therapy.Naturally occurring mutations were found both in acute and chronic subjects.In the present review we examine and discuss the most recent available data about HBV genetic variability and its significance.Patrizia Caligiuri Rita Cerruti Giancarlo Icardi Bianca Bruzzone 2016World Journal of Gastroenterology2016,22,1:25
4Pancreatic metastases from renal cell carcinoma:The state of the art显示文摘Pancreatic metastases are rare,with a reported incidence varying from 1.6%to 11%in autopsy studies of patients with advanced malignancy.In clinical series,the frequency of pancreatic metastases ranges from 2%to 5%of all pancreatic malignant tumors.However,the pancreas is an elective site for metastases from carcinoma of the kidney and this peculiarity has been reported by several studies.The epidemiology,clinical presentation,and treatment of pancreatic metastases from renal cell carcinoma are known from singleinstitution case reports and literature reviews.Thereis currently very limited experience with the surgical resection of isolated pancreatic metastasis,and the role of surgery in the management of these patients has not been clearly defined.In fact,for many years pancreatic resections were associated with high rates of morbidity and mortality,and metastatic disease to the pancreas was considered to be a terminal-stage condition.More recently,a significant reduction in the operative risk following major pancreatic surgery has been demonstrated,thus extending the indication for these operations to patients with metastatic disease.Roberto Ballarin Mario Spaggiari Nicola Cautero Nicola De Ruvo Roberto Montalti Cristina Longo Anna Pecchi Patrizia Giacobazzi Giuseppina De Marco Giuseppe D’Amico Giorgio Enrico Gerunda Fabrizio Di Benedetto 2011World Journal of Gastroenterology2011,17,43:21

6Obesity and colorectal cancer:Role of adipokines in tumor initiation and progression显示文摘Obesity-associated diseases account for a large portion of public health challenges.Among obesity-related disorders,a direct and independent relationship has been ascertained for colorectal cancer(CRC).The evidence that adipocyte hypertrophy and excessive adipose tissue accumulation(mainly visceral)can promote pathogenic adipocyte and adipose tissue-related diseases,has led to formulate the concept of'adiposopathy',defined as adipocyte and adipose tissue dysfunction that contributes to metabolic syndrome.Adipose tissue can,indeed,be regarded as an important and highly active player of the innate immune response,in which cytokine/adipokine secretion is responsible for a paracrine loop between adipocytes and macrophages,thus contributing to the systemic chronic low-grade inflammation associated with visceral obesity,which represents a favorable niche for tumor development.The adipocyte itself participates as a central mediator of this inflammatory response in obese individuals by secreting hormones,growth factors and proinflammatory cytokines,which are of particular relevance for the pathogenesis of CRC.Among adipocyte-secreted hormones,the most relevant to colorectal tumorigenesis are adiponectin,leptin,resistin and ghrelin.All these molecules have been involved in cell growth and proliferation,as well as tumor angiogenesis and it has been demonstrated that their expression changes from normal colonic mucosa to adenoma and adenocarcinoma,suggesting their involvement in multistep colorectal carcinogenesis.These findings have led to the hypothesis that an unfavorable adipokine profile,with a reduction of those with an anti-inflammatory and anti-cancerous activity,might serve as a prognostic factor in CRC patients and that adipokines or their analogues/antagonists might become useful agents in the management or chemoprevention of CRC.Silvia Riondino Mario Roselli Raffaele Palmirotta David Della-Morte Patrizia Ferroni Fiorella Guadagni 2014World Journal of Gastroenterology2014,20,18:20
7Molecular pathogenesis of bone metastases in breast cancer: Proven and emerging therapeutic targets显示文摘Metastatic occurrence is the principal cause of death in breast cancer patients. The high osteotropism makes breast cancer the most common primary tumor type associated with metastatic bone disease. The peculiar clinical aspects associated with metastases limited to the skeletal system suggest considering these cases as a distinctive subset of metastatic patients with a better prognosis. Because bone is frequently the first metastatic site in disease relapse, it is feasible that the next improvement in therapeutic options for bone metastatic disease could be associated with an improvement of survival expectation and quality of life in breast cancer patients. Study of the molecular basis of bone remodeling and breast cancer osteotropism has allowed identification of several therapeutic candidates involved in formation and progression of bone metastases. These targets are frequently the determinants of positive feedback between the tumor and bone cells whose clinical outcome is osteolytic lesions. In this review, we discuss the physiopathologic features underlying targeted therapeutic strategies aimed at interfering with the aberrant bone remodeling associated with breast cancer metastases.Nadia Rucci Patrizia Sanità Simona Delle Monache Edoardo Alesse Adriano Angelucci 2014World Journal of Clinical Oncology2014,5,3:18
8Intranasal nerve growth factor bypasses the blood-brain barrier and affects spinal cord neurons in spinal cord injury显示文摘The purpose of this work was to investigate whether,by intranasal administration,the nerve growth factor bypasses the blood-brain barrier and turns over the spinal cord neurons and if such therapeutic approach could be of value in the treatment of spinal cord injury.Adult Sprague-Dawley rats with intact and injured spinal cord received daily intranasal nerve growth factor administration in both nostrils for 1 day or for 3 consecutive weeks.We found an increased content of nerve growth factor and enhanced expression of nerve growth factor receptor in the spinal cord 24 hours after a single intranasal administration of nerve growth factor in healthy rats,while daily treatment for 3 weeks in a model of spinal cord injury improved the deficits in locomotor behaviour and increased spinal content of both nerve growth factor and nerve growth factor receptors.These outcomes suggest that the intranasal nerve growth factor bypasses blood-brain barrier and affects spinal cord neurons in spinal cord injury.They also suggest exploiting the possible therapeutic role of intranasally delivered nerve growth factor for the neuroprotection of damaged spinal nerve cells.Luigi Aloe Patrizia Bianchi Alberto De Bellis Marzia Soligo Maria Luisa Rocco 2014Neural Regeneration Research2014,9,10:17

10Nonalcoholic fatty liver disease and liver transplantation-Where do we stand?显示文摘Nonalcoholic fatty liver disease/nonalcoholic steatohepatitis(NAFLD/NASH) is a challenging and multisystem disease that has a high socioeconomic impact. NAFLD/NASH is a main cause of macrovesicular steatosis and has multiple impacts on liver transplantation(LT), on patients on the waiting list for transplant, on posttransplant setting as well as on organ donors. Current data indicate new trends in the area of chronic liver disease. Due to the increased incidence of metabolic syndrome(Met S) and its components, NASH cirrhosis and hepatocellular carcinoma caused by NASH will soon become a major indication for LT. Furthermore, due to an increasing incidence of Met S and, consequently, NAFLD, there will be more steatotic donor livers and less high quality organs available for LT, in addition to a lack of available liver allografts. Patients who have NASH and are candidates for LT have multiple comorbidities and are unique LT candidates. Finally, we discuss long-term grafts and patient survival after LT, the recurrence of NASH and NASH appearing de novo after transplantation. In addition, we suggest topics and areas that require more research for improving the health care of this increasing patient population.Ivana Mikolasevic Tajana Filipec-Kanizaj Maja Mijic Ivan Jakopcic Sandra Milic Irena Hrstic Nikola Sobocan Davor Stimac Patrizia Burra 2018World Journal of Gastroenterology2018,24,14:14
11Inflammation and colorectal cancer, when microbiota-host mutualism breaks显示文摘Structural changes in the gut microbial community have been shown to accompany the progressive development of colorectal cancer.In this review we discuss recent hypotheses on the mechanisms involved in the bacteria-mediated carcinogenesis,as well as the triggering factors favoring the shift of the gut microbiota from a mutualistic to a pro-carcinogenic configuration.The possible role of inflammation,bacterial toxins and toxic microbiota metabolites in colorectal cancer onset is specifically discussed.On the other hand,the strategic role of inflammation as the keystone factor in driving microbiota to become carcinogenic is suggested.As a common outcome of different environmental and endogenous triggers,such as diet,aging,pathogen infection or genetic predisposition,inflammation can compromise the microbiota-host mutualism,forcing the increase of pathobionts at the expense of health-promoting groups,and allowing the microbiota to acquire an overall pro-inflammatory configuration.Consolidating inflammation in the gut,and favoring the bloom of toxigenic bacterial drivers,these changes in the gut microbial ecosystem have been suggested as pivotal in promoting carcinogenesis.In this context,it will become of primary importance to implement dietary or probiotics-based interventions aimed at preserving the microbiota-host mutualism along aging,counteracting deviations that favor a pro-carcinogenic microbiota asset.Marco Candela Silvia Turroni Elena Biagi Franck Carbonero Simone Rampelli Carla Fiorentini Patrizia Brigidi 2014World Journal of Gastroenterology2014,20,4:13
12Neoplastic disease after liver transplantation: focus on de novo neoplasms显示文摘De novo neoplasms account for almost 30% of deaths 10 years after liver transplantation and are the most common cause of mortality in patients surviving at least 1 year after transplant. The risk of malignancy is two to four times higher in transplant recipients than in an age- and sex-matched population, and cancer is expected to surpass cardiovascular complications as the primary cause of death in transplanted patients within the next 2 decades. Since exposure to immunosuppression is associated with an increased frequency of developing neoplasm, long-term immunosuppression should be therefore minimized. Promising results in the prevention of hepatocellular carcinoma(HCC) recurrence have been reported with the use of m TOR inhibitors including everolimus and sirolimus and the ongoing open-label prospective randomized controlled SILVER. Study will provide more information on whether sirolimus-containing vs m TOR-inhibitorfree immunosuppression is more efficacious in reducing HCC recurrence.Patrizia Burra Kryssia I Rodriguez-Castro 2015World Journal of Gastroenterology2015,21,29:9
13Therapeutic approaches for portal biliopathy: A systematic review显示文摘Portal biliopathy(PB) is defined as the presence of biliary abnormalities in patients with non-cirrhotic/nonneoplastic extrahepatic portal vein obstruction(EHPVO) and portal cavernoma(PC). The pathogenesis of PB is due to ab extrinseco compression of bile ducts by PC and/or to ischemic damage secondary to an altered biliary vascularization in EHPVO and PC. Although asymptomatic biliary abnormalities can be frequently seen by magnetic resonance cholangiopancreatography in patients with PC(77%-100%), only a part of these(5%-38%) are symptomatic. Clinical presentation includes jaundice, cholangitis, cholecystitis, abdominal pain, and cholelithiasis. In this subset of patients is required a specific treatment. Different therapeutic approaches aimed to diminish portal hypertension and treat biliary strictures are available. In order to decompress PC, surgical porto-systemic shunt or transjugular intrahepatic porto-systemic shunt can be performed, and treatment on the biliary stenosis includes endoscopic(Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy, balloon dilation, stone extraction, stent placement) and surgical(bilioenteric anastomosis, cholecystectomy) approaches. Definitive treatment of PB often requires multiple and combined interventions both on vascular and biliary system. Liver transplantation can be considered in patients with secondary biliary cirrhosis, recurrent cholangitis or unsuccessful control of portal hypertension.Irene Franceschet Alberto Zanetto Alberto Ferrarese Patrizia Burra Marco Senzolo 2016World Journal of Gastroenterology2016,22,45:9
14Epilepsy associated tumors: Review article显示文摘Long-term epilepsy associated tumors(LEAT) represent a well known cause of focal epilepsies. Glioneuronaltumors are the most frequent histological type consisting of a mixture of glial and neuronal elements and most commonly ariseing in the temporal lobe. Cortical dysplasia or other neuronal migration abnormalities often coexist. Epilepsy associated with LEAT is generally poorly controlled by antiepileptic drugs while, on the other hand, it is high responsive to surgical treatment. However the best management strategy of tumor-related focal epilepsies remains controversial representing a contemporary issues in epilepsy surgery. Temporo-mesial LEAT have a widespread epileptic networkwith complex epileptogenic mechanisms. By using an epilepsy surgery oriented strategy LEAT may have an excellent seizure outcome therefore surgical treatment should be offered early, irrespective of pharmacoresistance, avoiding both the consequences of uncontrolled seizures as well as the side effects of prolonged pharmacological therapy and the rare risk of malignant transformation.Marco Giulioni Gianluca Marucci Matteo Martinoni Anna Federica Marliani Francesco Toni Fiorina Bartiromo Lilia Volpi Patrizia Riguzzi Francesca Bisulli Ilaria Naldi Roberto Michelucci Agostino Baruzzi Paolo Tinuper Guido Rubboli 2014World Journal of Clinical Cases2014,2,11:9
15Outcome of nonerosive gastro-esophageal reflux disease patients with pathological acid exposure显示文摘AIM: To assess the management and outcome of nonerosive gastro-esophageal reflux disease (NERD) patients who were identified retrospectively, after a 5-year follow-up.METHODS: We included patients with gastro-esophageal reflux disease (GERD) symptoms who had a negative endoscopy result and pathological 24-h esophageal pH-monitoring while off therapy. We interviewed them after an average period of 5 years (range 3.5-7 years) by means of a structured questionnaire to assess presence of GERD symptoms, related therapy, updated en-doscopic data and other features. We assessed predictors of esophagitis development by means of univariate and multivariate statistical analysis.RESULTS: 260 patients (137 women) were included. Predominant GERD symptoms were heartburn andregurgitation in 103/260 (40%). 70% received a maintenance treatment, which was proton pump inhibitor (PPI) in 55% of cases. An average number of 1.5 symptomatic relapses per patient/year of follow-up were observed. A progression to erosive gastro-esophageal reflux disease (ERD) was found in 58/193 (30.0%) of patients undergoing repeat endoscopy; 72% of these were Los Angeles grade A-B. CONCLUSION: This study shows that progression to ERD occurs in about 5% of NERD cases per year, despite therapy. Only two factors consistently and independently influence progression: smoking and absence of PPI therapy.Fabio Pace Stefano Pallotta Gianpiero Manes Annalisa de Leone Patrizia Zentilin Luigi Russo Vincenzo Savarino Matteo Neri Enzo Grossi Rosario Cuomo 2009World Journal of Gastroenterology2009,15,45:8
16Precision medicine in gastric cancer显示文摘Gastric cancer(GC)is a complex disease linked to a series of environmental factors and unhealthy lifestyle habits,and especially to genetic alterations.GC represents the second leading cause of cancer-related deaths worldwide.Its onset is subtle,and the majority of patients are diagnosed once the cancer is already advanced.In recent years,there have been innovations in the management of advanced GC including the introduction of new classifications based on its molecular characteristics.Thanks to new technologies such as next-generation sequencing and microarray,the Cancer Genome Atlas and Asian Cancer Research Group classifications have also paved the way for precision medicine in GC,making it possible to integrate diagnostic and therapeutic methods.Among the objectives of the subdivision of GC into subtypes is to select patients in whom molecular targeted drugs can achieve the best results;many lines of research have been initiated to this end.After phase III clinical trials,trastuzumab,anti-Erb-B2 receptor tyrosine kinase 2(commonly known as ERBB2)and ramucirumab,anti-vascular endothelial growth factor receptor 2(commonly known as VEGFR2)monoclonal antibodies,were approved and introduced into first-and second-line therapies for patients with advanced/metastatic GC.However,the heterogeneity of this neoplasia makes the practical application of such approaches difficult.Unfortunately,scientific progress has not been matched by progress in clinical practice in terms of significant improvements in prognosis.Survival continues to be low in contrast to the reduction in deaths from many common cancers such as colorectal,lung,breast,and prostate cancers.Although several target molecules have been identified on which targeted drugs can act and novel products have been introduced into experimental therapeutic protocols,the overall approach to treating advanced stage GC has not substantially changed.Currently,surgical resection with adjuvant or neoadjuvant radiotherapy and chemotherapy are the most effective treatments for this disease.Future research should not underestimate the heterogeneity of GC when developing diagnostic and therapeutic strategies aimed toward improving patient survival.Patrizia Bonelli Antonella Borrelli Franca Maria Tuccillo Lucrezia Silvestro Raffaele Palaia Franco Maria Buonaguro 2019World Journal of Gastrointestinal Oncology2019,11,10:8
17A new oral formulation for the release of sodium butyrate in the ileo-cecal region and colon显示文摘AIM: To develop a new formulation with hydroxy propyl methyl cellulose and Shellac coating for extended and selective delivery of butyrate in the ileo-caecal region and colon. METHODS: One-gram sodium butyrate coated tablets containing 13C-butyrate were orally administered to 12 healthy subjects and 12 Crohn's disease patients and the rate of 13C-butyrate absorption was evaluated by 13CO2 breath test analysis for eight hours. Tauroursodeoxycholic acid (500 mg) was co-administered as a biomarker of oro-ileal transit time to determine also the site of release and absorption of butyrate by the time of its serum maximum concentration. RESULTS: The coated formulation delayed the 13C-butyrate release by 2-3 h with respect to the uncoated tablets. Sodium butyrate was delivered in the intestine of all subjects and a more variable transit time was found in Crohn's disease patients than in healthy subjects. The variability of the peak 13CO2 in the kinetic release of butyrate was explained by the inter-subject variability in transit time. However, the coating chosen ensured an efficient release of the active compound even in patients with a short transit time. CONCLUSION: Simultaneous evaluation of breath 13CO2 and tauroursodeoxycholic acid concentration- time curves has shown that the new oral formulation consistently releases sodium butyrate in the ileo-cecal region and colon both in healthy subjects and Crohn's disease patients with variable intestinal transit time. This formulation may be of therapeutic value in inflammatory bowel disease patients due to the appropriate release of the active compound.Aldo Roda Patrizia Simoni Maria Magliulo Paolo Nanni Mario Baraldini Giulia Roda Enrico Roda 2007World Journal of Gastroenterology2007,13,7:8
18Is osteoporosis a peculiar association with primary biliary cirrhosis?显示文摘AIM: (1) To compare the prevalence of osteoporosis (t-score ≤-2.5 SD) between stage Ⅳ PBC patients, and two groups of age- and sex-matched controls: one with hepatitis C virus (HCV)-related cirrhosis, and the other one consisting of a group of healthy subjects from the general population; (2) to identify the main risk factors for the development of bone loss.METHODS: Thirty-five stage Ⅳ PBC patients (mean age 52.5±10 years), 49 females with HCV-related cirrhosis (mean age 52.9±5.8 years) and 33 healthy females (mean age 51.8+2.22 years) were enrolled in the study. Bone metabolism was evaluated by measuring serum calcium corrected for serum albumin (Ca corr.), 25-hydroxy vitamin D (25-OH vit D), parathyroid hormone, osteocalcin.Bone mineral density (BMD) was assessed at the lumbar spine by dual-photon X-ray absorptiometry.RESULTS: Osteoporosis was present in 5/35 PBC patients (14.2%) and in 7/49 HCV-related cirrhotic patients (14.3%),without any statistical difference between the two groups.Among healthy control subjects, none had osteoporosis.No difference was found between the three groups in serum parameters of bone metabolism. Univariate analysis showed that menopausal state and low BMI were significantly correlated with osteoporosis. Multivariate regression analysis showed that menopausal status, BMI <23, and old age were independent variables significantly correlated with osteoporosis.CONCLUSION: PBC in itself has no negative influence on BMD. End-stage liver disease patients carry a disease-specific risk for osteoporosis, but have an effective risk of bone loss in relation to individual potential risk for each patient. A practical message should be taken into account, that is, every effort should be made to prevent osteoporosis when a patient has simple osteopenia, or if it is a woman in or near menopausal age.Annarosa Floreani Andrea Mega Valentina Camozzi Vincenzo Baldo Mario Plebani Patrizia Burra Giovanni Luisetto 2005World Journal of Gastroenterology2005,11,34:7

20Liver transplantation for viral hepatitis in 2015显示文摘Liver transplantation(LT) is a life-saving treatment forpatients with end-stage liver disease and for patients with liver cell cancer related to liver disease. Acute and chronic liver diseases related to hepatitis viruses are between the main indications for liver transplantation. The risk of viral reinfection after transplantation is the main limiting factor in these indications. Before the availability of antiviral prophylaxis, hepatitis B virus(HBV) recurrence was universal in patients who were HBV DNA-positive before transplantation. The natural history of recurrent HBV was accelerated by immunosuppression, and it progressed rapidly to graft failure and death. Introduction of post-transplant prophylaxis with immunoglobulin alone first, and associated to antiviral drugs later, drastically reduced HBV recurrence, resulting in excellent long-term outcomes. On the contrary, recurrence of hepatitis C is the main cause of graft loss in most transplant programs. Overall, patient and graft survival after LT for hepatitis C virus(HCV)-associated cirrhosis is inferior compared with other indications. However, successful pretransplant or post transplant antiviral therapy has been associated with increased graft and overall survival. Until recently, the combination of pegylated interferon and ribavirin was the standard of care for the treatment of patients with chronic hepatitis C. Highly active antiviral compounds have been developed over the past decade, thanks to new in vitro systems to study HCV entry, replication, assembly, and release.alberto ferrarese alberto zanetto martina gambato ilaria bortoluzzi elena nadal giacomo germani marco senzolo patrizia burra francesco paolo russo 2016World Journal of Gastroenterology2016,22,4:7
