| 1 | Bridging and downstaging treatments for hepatocellular carcinoma in patients on the waiting list for liver transplantation显示文摘Several therapeutic procedures have been proposed as bridging treatments for patients with hepatocellular carcinoma(HCC)awaiting liver transplantation(LT).The most used treatments include transarterial chemoembolization and radiofrequency ablation.Surgical resection has also been successfully used as a bridging procedure,and LT should be considered a rescue treatment in patients with previous HCC resection who experience tumor recurrence or post-treatment severe decompensation of liver function.The aims of bridging treatments include decreasing the waiting list dropout rate before transplantation,reducing HCC recurrence after transplantation,and improving post-transplant overall survival.To date,no data from prospective randomized studies are available;however,for HCC patients listed for LT within the Milan criteria,prolonging the waiting time over 6-12 mo is a risk factor for tumor spread.Bridging treatments are useful in containing tumor progression and decreasing dropout.Furthermore,the response to pre-LT treatments may represent a surrogate marker of tumor biological aggressiveness and could therefore be evaluated to prioritize HCC candidates for LT.Lastly,although a definitive conclusion can not be reached,the experiences reported to date suggest a positive impact of these treatments on both tumor recurrence and post-transplant patient survival.Advanced HCC may be downstaged to achieve and maintain the current conventional criteria for inclusion in the waiting list for LT.Recent studies have demonstrated that successfully downstaged patients can achieve a 5-year survival rate comparable to that of patients meeting the conventional criteria without requiring downstaging. | Maurizio Pompili Giampiero Francica Francesca Romana Ponziani Roberto Iezzi Alfonso Wolfango Avolio | 2013 | World Journal of Gastroenterology2013，19，43： | 24 |
| 2 | Portal vein thrombosis in cirrhosis: Why a well-known complication is still matter of debate显示文摘Portal vein thrombosis(PVT)represents a well-known complication during the natural course of liver cirrhosis(LC),ranging from asymptomatic cases to lifethreating conditions related to portal hypertension and hepatic decompensation.Portal flow stasis,complex acquired hypercoagulable disorders and exogenous factors leading to endothelial dysfunction have emerged as key factors for PVT development.However,PVT occurrence remains unpredictable and many issues regarding its natural history,prognostic significance and treatment are still elusive.In particular although spontaneous resolution or disease stability occur in most cases of PVT,factors predisposing to disease progression or recurrence after spontaneous recanalization are not clarified as yet.Moreover,PVT impact on LC outcome is still debated,as PVT may represent itself a consequence of liver fibrosis and hepatic dysfunction progression.Anticoagulation and transjugular intrahepatic portosystemic shunt are considered safe and effective in this setting and are recommended in selected cases,even if the safer therapeutic option and the optimal therapy duration are still unknown.Nevertheless,their impact on mortality rates should be addressed more extensively.In this review we present the most debated questions regarding PVT,whose answers should come from prospective cohort studies and large sample-size randomized trials. | Mariella Faccia Maria Elena Ainora Francesca Romana Ponziani Laura Riccardi Matteo Garcovich Antonio Gasbarrini Maurizio Pompili Maria Assunta Zocco | 2019 | World Journal of Gastroenterology2019，25，31： | 23 |
| 3 | Treatment of hepatocellular carcinoma in patients with portal vein tumor thrombosis: Beyond the known frontiers显示文摘Hepatocellular carcinoma is one of the most frequent malignant tumors worldwide:Portal vein tumor thrombosis(PVTT)occurs in about 35%-50%of patients and represents a strong negative prognostic factor,due to the increased risk of tumor spread into the bloodstream,leading to a high recurrence risk.For this reason,it is a contraindication to liver transplantation and in several prognostic scores sorafenib represents its standard of care,due to its antiangiogenetic action,although it can grant only a poor prolongation of life expectancy.Recent scientific evidences lead to consider PVTT as a complex anatomical and clinical condition,including a wide range of patients with different prognosis and new treatment possibilities according to the degree of portal system involvement,tumor biological aggressiveness,complications caused by portal hypertension,patient’s clinical features and tolerance to antineoplastic treatments.The median survival has been reported to range between 2.7 and 4 mo in absence of therapy,but it can vary from 5 mo to 5 years,thus depicting an extremely variable scenario.For this reason,it is extremely important to focus on the most adequate strategy to be applied to each group of PVTT patients. | Lucia Cerrito Brigida Eleonora Annicchiarico Roberto Iezzi Antonio Gasbarrini Maurizio Pompili Francesca Romana Ponziani | 2019 | World Journal of Gastroenterology2019，25，31： | 21 |
| 4 | Eubiotic properties of rifaximin: Disruption of the traditional concepts in gut microbiota modulation显示文摘Antibiotics are usually prescribed to cure infections but they also have significant modulatory effects on the gut microbiota. Several alterations of the intestinal bacterial community have been reported during antibiotic treatment, including the reduction of beneficial bacteria as well as of microbial alpha-diversity. Although after the discontinuation of antibiotic therapies it has been observed a trend towards the restoration of the original condition, the new steady state is different from the previous one, as if antibiotics induced some kind of irreversible perturbation of the gut microbial community. The poorly absorbed antibiotic rifaximin seem to be different from the other antibiotics, because it exerts non-traditional effects additional to the bactericidal/bacteriostatic activity on the gut microbiota. Rifaximin is able to reduce bacterial virulence and translocation, has anti-inflammatory properties and has been demonstrated to positively modulate the gut microbial composition. Animal models, culture studies and metagenomic analyses have demonstrated an increase in Bifidobacterium, Faecalibacterium prausnitzii and Lactobacillus abundance after rifaximin treatment, probably consequent to the induction of bacterial resistance, with no major change in the overall gut microbiota composition. Antibiotics are therefore modulators of the symbiotic relationship between the host and the gut microbiota. Specific antibiotics, such as rifaximin, can also induce eubiotic changes in the intestinal ecosystem; this additional property may represent a therapeutic advantage in specific clinical settings. | Francesca Romana Ponziani Maria Assunta Zocco Francesca D’Aversa Maurizio Pompili Antonio Gasbarrini | 2017 | World Journal of Gastroenterology2017，23，25： | 17 |
| 5 | Effect of rifaximin on gut microbiota composition in advanced liver disease and its complications显示文摘Liver cirrhosis is a paradigm of intestinal dysbiosis. The qualitative and quantitative derangement of intestinal microbial community reported in cirrhotic patients seems to be strictly related with the impairment of liver function. A kind of gut microbial 'fingerprint',characterized by the reduced ratio of 'good' to 'potentially pathogenic' bacteria has recently been outlined,and is associated with the increase in Model for End-Stage Liver Disease and Child Pugh scores. Moreover,in patients presenting with cirrhosis complications such as spontaneous bacterial peritonitis(SBP),hepatic encephalopathy(HE),and,portal hypertension intestinal microbiota modifications or the isolation of bacteria deriving from the gut are commonly reported. Rifaximin is a non-absorbable antibiotic used in the management of several gastrointestinal diseases. Beyond bactericidal/bacteriostatic,immune-modulating and anti-inflammatory activity,a little is known about its interaction with gut microbial environment. Rifaximin has been demonstrated to exert beneficial effects on cognitive function in patients with HE,and also to prevent the development of SBP,to reduce endotoxemia and to improve hemodynamics in cirrhotics. These results are linked to a shift in gut microbes functionality,triggering the production of favorable metabolites. The low incidence of drug-related adverse events due to the small amount of circulating drug makes rifaximin a relatively safe antibiotic for the modulation of gut microbiota in advanced liver disease. | Francesca Romana Ponziani Viviana Gerardi Silvia Pecere Francesca D'Aversa Loris Lopetuso Maria Assunta Zocco Maurizio Pompili | 2015 | World Journal of Gastroenterology2015，21，43： | 16 |
| 6 | Combined locoregional treatment of patients withhepatocellular carcinoma: state of the art显示文摘In recent years, a combination of intervention therapies has been widely applied in the treatment of hepatocellular carcinoma(HCC). One such combined strategy is based on the combination of the percutaneous approach, such as radiofrequency ablation(RFA), and the intra-arterial locoregional approach, such as trans-arterial chemoembolization(TACE). Several types of evidence have supported the feasibility and benefit of combined therapy, despite some studies reporting conflicting results and outcomes. The aim of this review was to explain the technical aspects of different combined treatments and to comprehensively analyze and compare the clinical efficacy and safety of this combined treatment option and monotherapy, either as TACE or RFA alone, in order to provide clinicians with an unbiased opinion and valuable information. Based on a literature review and our experience, combined treatment seems to be a safe and effective option in the treatment of patients with early/intermediate HCC when surgical resection is not feasible; furthermore, this approach provides better results than RFA and TACE alone for the treatment of large HCC, defined as those exceeding 3 cm in size. It can also expand the indication for RFA to previously contraindicated 'complex cases', with increased risk of thermal ablation related complications due to tumor location, or to 'complex patients' with high bleeding risk. | Roberto Iezzi Maurizio Pompili Alessandro Posa Giuseppe Coppola Antonio Gasbarrini Lorenzo Bonomo | 2016 | World Journal of Gastroenterology2016，22，6： | 15 |
| 7 | Subclinical atherosclerosis is linked to small intestinal bacterial overgrowth via vitamin K2-dependent mechanisms显示文摘AIM To assess the rate of matrix Gla-protein carboxylation in patients with small intestinal bacterial overgrowth(SIBO) and to decipher its association with subclinical atherosclerosis.METHODS Patients with suspected SIBO who presented with a low risk for cardiovascular disease and showed no evidence of atherosclerotic plaques were included in the study. A glucose breath test was performed in order to confirm the diagnosis of SIBO and vascular assessment was carried out by ultrasound examination. Plasma levels of the inactive form of MGP(dephosphorylateduncarboxylated matrix Gla-protein) were quantified by ELISA and vitamin K2 intake was estimated using a food frequency questionnaire.RESULTS Thirty-nine patients were included in the study. SIBO was confirmed in 12/39(30.8%) patients who also presented with a higher concentration ofdephosphorylated-uncarboxylated matrix Gla-protein(9.5 μg/L vs 4.2 μg/L; P = 0.004). Arterial stiffness was elevated in the SIBO group(pulse-wave velocity 10.25 m/s vs 7.68 m/s; P = 0.002) and this phenomenon was observed to correlate linearly with the levels of dephosphorylated-uncarboxylated matrix Gla-protein(β = 0.220, R2 = 0.366, P = 0.03). Carotid intima-media thickness and arterial calcifications were not observed to be significantly elevated as compared to controls.CONCLUSION SIBO is associated with reduced matrix Gla-protein activation as well as arterial stiffening. Both these observations are regarded as important indicators of subclinical atherosclerosis. Hence, screening for SIBO, intestinal decontamination and supplementation with vitamin K2 has the potential to be incorporated into clinical practice as additional preventive measures. | Francesca Romana Ponziani Maurizio Pompili Enrico Di Stasio Maria Assunta Zocco Antonio Gasbarrini Roberto Flore | 2017 | World Journal of Gastroenterology2017，23，7： | 9 |
| 8 | Ethanol injection is highly effective for hepatocellular carcinoma smaller than 2cm显示文摘AIM:To analyze the long-term prognosis in a cohort of western cirrhotic patients with single hepatocellular carcinoma treated with ethanol injection.METHODS:One-hundred forty-eight patients with solitary hepatocellular carcinoma were enrolled.The tumor diameter was lower than 2 cm in 47 patients but larger in the remaining 101 patients.The impact of some pretreatment clinical and laboratory parameters and of tumor recurrence on patients' survival was assessed.RESULTS:Among the pre-treatment parameters,only a tumor diameter of less than 2 cm was an independent prognostic factor of survival.The occurrence of new nodules in other liver segments and the neoplastic portal invasion were linked to a poorer prognosis at univariate analysis.Patients with a single hepatocellular carcinoma smaller than 2 cm showed a better 5-year cumulativesurvival(73.0% vs 47.9%)(P = 0.009),3-year local recurrence rate(29.1% vs 51.5%)(P = 0.011),and 5-year distant intrahepatic recurrence rate(52.9% vs 62.8%)(P = 0.054) compared to patients with a larger tumor.CONCLUSION:The 5-year survival rate of patients with single hepatocellular carcinoma < 2 cm undergoing ethanol injection is excellent and comparable to that achieved using radiofrequency ablation. | Maurizio Pompili Erica Nicolardi Valeria Abbate Luca Miele Laura Riccardi Marcello Covino Nicoletta De Matthaeis Antonio Grieco Raffaele Landolfi Gian Ludovico Rapaccini | 2011 | World Journal of Gastroenterology2011，17，26： | 6 |

| 10 | Viral hepatitis and hepatocellular carcinoma:From molecular pathways to the role of clinical surveillance and antiviral treatment显示文摘Hepatocellular carcinoma(HCC)is a global health challenge.Due to the high prevalence in low-income countries,hepatitis B virus(HBV)and hepatitis C virus infections remain the main risk factors for HCC occurrence,despite the increasing frequencies of non-viral etiologies.In addition,hepatitis D virus coinfection increases the oncogenic risk in patients with HBV infection.The molecular processes underlying HCC development are complex and various,either independent from liver disease etiology or etiology-related.The reciprocal interlinkage among non-viral and viral risk factors,the damaged cellular microenvironment,the dysregulation of the immune system and the alteration of gutliver-axis are known to participate in liver cancer induction and progression.Oncogenic mechanisms and pathways change throughout the natural history of viral hepatitis with the worsening of liver fibrosis.The high risk of cancer incidence in chronic viral hepatitis infected patients compared to other liver disease etiologies makes it necessary to implement a proper surveillance,both through clinical-biochemical scores and periodic ultrasound assessment.This review aims to outline viral and microenvironmental factors contributing to HCC occurrence in patients with chronic viral hepatitis and to point out the importance of surveillance programs recommended by international guidelines to promote early diagnosis of HCC. | Leonardo Stella Francesco Santopaolo Antonio Gasbarrini Maurizio Pompili Francesca Romana Ponziani | 2022 | World Journal of Gastroenterology2022，28，21： | 4 |
| 11 | Tumor necrosis factor-α inhibitors and chronic hepatitis C:A comprehensive literature review显示文摘Tumor necrosis factor-α(TNF-α)inhibitors are known to increase reactivation of concurrent chronic hepatitis B,but their impact on the hepatitis C virus(HCV)is controversial.Some conditions of immunosuppression,such as liver transplantation,typically cause an increase in the rate of HCV evolution.Inhibition of TNF-α,a cytokine involved in the apoptotic signaling pathway of hepatocytes infected by HCV,could potentially increase viral replication.Currently available clinical data appear to contradict this hypothesis.A review of medical literature revealed that a total of 216 patients with HCV were exposed to one or more treatments with TNF-αinhibitors,with a median observation time of 1.2 years and 260 cumulative patient-years of exposure.Only three cases of drug withdrawal due to suspected HCV liver disease recrudescence were reported.Treatment with TNF-αinhibitors in patients with HCV infection appears to be safe in the short term,but there are insufficient data to assess their long-term safety.Universal screening for HCV before beginning treatment with TNF-αinhibitors is currently controversial.The presence of HCV is not a contraindication to therapy with TNF-αinhibitors,with the exception of cirrhotic patients.In cases of cirrhosis,the benefit/risk ratio should be evaluated at the individual level.Prior to treatment with TNF-αinhibitors,patients with HCV should be referred to a hepatologist to determine the necessity of hepatic disease assessment,using liver biopsy or noninvasive methods,and the potential indication for antiviral therapy.In patients with HCV infection who are treated with TNF-αinhibitors,liver function monitoring every three months is advised. | Maurizio Pompili Marco Biolato Luca Miele Antonio Grieco | 2013 | World Journal of Gastroenterology2013，19，44： | 4 |
| 12 | Future of liver disease in the era of direct acting antivirals for the treatment of hepatitis C显示文摘Hepatitis C virus(HCV) infection has been a global health problem for decades, due to the high number of infected people and to the lack of effective and welltolerated therapies. In the last 3 years, the approval of new direct acting antivirals characterized by high rates of virological clearance and excellent tolerability has dramatically improved HCV infection curability, especially for patients with advanced liver disease and for liver transplant recipients. Long-term data about the impact of the new direct acting antivirals on liver fibrosis and liver disease-related outcomes are not yet available, due to their recent introduction. However, previously published data deriving from the use of pegylatedinterferon and ribavirin lead to hypothesizing that we are going to observe, in the future, a reduction in mortality and in the incidence of hepatocellular carcinoma, as well as a regression of fibrosis for people previously affected by hepatitis C. In the liver transplant setting, clinical improvement has already been described after treatment with the new direct acting antivirals, which has often led to patients delisting. In the future, this may hopefully reduce the gap between liver organ request and availability, probably expanding liver transplant indications to other clinical conditions. Therefore, these new drugs are going to change the natural history of HCV-related liver disease and the epidemiology of HCV infection worldwide. However, the global consequences will depend on treatment accessibility and on the number of countries that could afford the use of the new direct acting antivirals. | Francesca Romana Ponziani Francesca Mangiola Cecilia Binda Maria Assunta Zocco Massimo Siciliano Antonio Grieco Gian Lodovico Rapaccini Maurizio Pompili Antonio Gasbarrini | 2017 | World Journal of Hepatology2017，9，7： | 3 |
| 13 | Usefulness of contrast enhanced ultrasound in monitoring therapeutic response after hepatocellular carcinoma treatment显示文摘In the last years, the development in the oncology field has been huge and rapid. In particular, the evaluation of response to anti-tumour treatments has been being object of intense research, producing significant changes. Response assessment after therapy in solid neoplasias has always used radiological imaging techniques, with tumour size reduction representing a presumed therapeutic efficacy. However, with the introduction of anti-angiogenetic drugs the evaluation of tumour size has become unsuitable because some tumours, under treatment, show only tumour perfusion changes rather than lesion shrinkage. Between different imaging techniques with contrast-enhancement, contrastenhanced ultrasound(CEUS) and, in particular, dynamic CEUS have arisen as a promising and non-invasive device for monitoring cancer treatments. Moreover, the introduction of perfusion software has even more refined the technique since it is able to provide quantitative parameters related to blood flow and blood volume that can be associated with tumour response and clinical outcome such as the progression free survival and the overall survival. Here, we give an overview of the current status of CEUS in monitoring hepatocellular carcinoma response to different kind of treatments. | Davide Roccarina Matteo Garcovich Maria Elena Ainora Laura Riccardi Maurizio Pompili Antonio Gasbarrini Maria Assunta Zocco | 2015 | World Journal of Hepatology2015，7，14： | 3 |
