Hug sign in intraprocedural cone-beam-CT to predict short-term response to combined treatment of hepatocellular carcinoma.

Objectives: Combined treatment of ablation and chemoembolization for hepatocellular carcinoma represents a promising therapy to increase treatment efficacy and improve patient survival. The "hug sign" is a recently introduced radiological sign consisting in deposition of beads/contrast agent during transarterial chemoembolization in the hyperemic area surrounding the post-ablation volume, seen during intraprocedural unenhanced cone-beam CT, that may indicate intraprocedural success. Aim of our retrospective study was to analyze the usefulness of the "hug sign" at the intraprocedural unenhanced cone-beam CT as an early predictor of response to combined treatment, based on the hug sign angle.

Safety and efficacy of endoscopic ultrasound-guided radiofrequency ablation for pancreatic insulinoma: A single-center experience.

Background/objectives: Insulinomas are rare, functioning pancreatic neuroendocrine neoplasms (pNEN), whose gold standard therapy is surgical resection. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a recent technique that has emerged as a minimally invasive therapeutic option for patients with pancreatic lesions not eligible for surgery. In this study, we aimed to describe a series of patients with unresectable pancreatic insulinoma treated with EUS-RFA.

COntrolling NUTritional Status (CONUT) as Predictive Score of Hospital Length of Stay (LOS) and Mortality: A Prospective Cohort Study in an Internal Medicine and Gastroenterology Unit in Italy.

Background: Hospital malnutrition affects nearly 30% of patients in medical wards and correlates with worse outcomes. An early assessment is necessary to stratify the risk of short-term outcomes and mortality. The predictive role of COntrolling NUTritional status (CONUT) score in this context has not yet been elucidated in Western countries.

Incidence and Impact of Refeeding Syndrome in an Internal Medicine and Gastroenterology Ward of an Italian Tertiary Referral Center: A Prospective Cohort Study.

Background: Refeeding syndrome (RS) is a neglected, potentially fatal syndrome that occurs in malnourished patients undergoing rapid nutritional replenishment after a period of fasting. The American Society for Parenteral and Enteral Nutrition (ASPEN) recently released new criteria for RS risk and diagnosis. Real-life data on its incidence are still limited.

Assessing Baveno VI criteria with liver stiffness measured using a new point-shear wave elastography technique (BAVElastPQ study).

Background And Aims: To date, no study has explored the potential role of ElastPQ, a novel point-SWE technique, in the assessment of clinically significant portal hypertension. The aim of our study was to determine a liver stiffness (LS) cut-off value measured by ElastPQ and laboratory parameters that could help to identify those patients who can safely avoid screening endoscopy.

Methods: Data were collected on 1422 patients who underwent ElastPQ measurement from January 2013 to January 2016 in our Department.

Contrast-Enhanced Ultrasound in the Short-Term Evaluation of Hepatocellular Carcinoma after Locoregional Treatment.

Background: Contrast-enhanced ultrasound (CEUS) with second-generation contrast agents performed 1 month after hepatocellular carcinoma (HCC) treatment is almost as sensitive as contrast-enhanced computed tomography (CECT) in depicting the residual tumor. However, the efficacy of CEUS performed early after the procedure is still debated.

Aim: We evaluated the diagnostic accuracy (DA) of CEUS for the assessment of tumor response shortly after locoregional therapy in patients with unresectable HCC.

Treatment of hepatocellular carcinoma in patients with portal vein tumor thrombosis: Beyond the known frontiers.

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.

Interventional oncology treatments for unresectable early stage HCC in patients with a high risk for intraprocedural bleeding: Is a single-step combined therapy safe and feasible?

Purpose: This study was designed to assess the feasibility and safety of a single-step combined therapy using radiofrequency ablation and transarterial chemoembolization (RFA + TACE) in patients with hepatocellular carcinoma (HCC) and uncontrolled coagulopathy. The study also aimed to compare the effectiveness of this approach with TACE alone, performed in a control group.

Material And Methods: One hundred and forty-three consecutive cirrhotic patients having a single HCC < 8 cm were enrolled in this observational prospective single-center study from January 2010 to June 2017 and were divided, according to coagulation tests, into three groups (A: low risk; B: intermediate risk and C: high risk of bleeding).

Regorafenib: a promising treatment for hepatocellular carcinoma.

: Hepatocellular carcinoma (HCC) is one of the most frequent malignant tumors with 854,000 new cases per year and represents the second most frequent cause of cancer-death. Despite surveillance, the number of patients that are diagnosed at a stage in which they are eligible for curative treatments ranges from 30% to 60%. Advanced HCC (BCLC-C) is characterized by a median survival of 6 months.

ACE I allele is associated with more severe portal hypertension in patients with liver cirrhosis: A pilot study.

Background: In liver cirrhosis, the renin-angiotensin-aldosterone system is involved in the pathogenesis of portal hypertension. Its effector, angiotensin II, is generated by angiotensin-converting enzyme (ACE). Serum ACE levels are affected by I/D polymorphism of its gene, with alleles I and D being associated, respectively, with lesser and greater activity of the enzyme.

Reverse time-dependent effect of alphafetoprotein and disease control on survival of patients with Barcelona Clinic Liver Cancer stage C hepatocellular carcinoma.

Aim: To characterize the survival of cirrhotic patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC) and to ascertain the factors predicting the achievement of disease control (DC).

Methods: The cirrhotic patients with BCLC stage C HCC evaluated by the Hepatocatt multidisciplinary group were subjected to the investigation. Demographic, clinical and tumor features, along with the best tumor response and overall survival were recorded.

Toxicity and risks from drug-to-drug interactions of new antivirals for chronic hepatitis C.

The new direct acting antivirals (DAAs), defined as those drugs that are effective in combinations without interferon, have totally changed HCV treatment and probably in few years will also totally change global landscape of advanced liver diseases. The advantage of DAAs is a low-risk/high-benefit ratio. Although overall adverse events during DAAs treatment are limited in frequency and severity, some toxicity issues emerged during the first years of real-life experience with these drugs.

A pilot study of capsule endoscopy after a standard meal for the detection and grading of oesophageal varices in cirrhotic patients.

Background: Capsule endoscopy has been proposed as an alternative to fibreoptic endoscopy for oesophageal varices evaluation in cirrhotics. However, it shows only moderate sensitivity compared to fibreoptic endoscopy.

Aim: To compare post-meal capsule endoscopy to fibreoptic endoscopy, based on the hypothesis that meal-induced increase of portal pressure can enhance its sensitivity.

Early prediction of response to sorafenib in patients with advanced hepatocellular carcinoma: the role of dynamic contrast enhanced ultrasound.

Background & Aims: Sorafenib has become the standard first-line treatment for patients with advanced HCC and acts by inducing alterations in tumor vascularity. We wanted to evaluate the feasibility of dynamic CEUS (D-CEUS) as a predictor of early tumor response to sorafenib and to correlate functional parameters with clinical efficacy end points.

Methods: Twenty-eight HCC patients treated with sorafenib 400mg bid were prospectively enrolled.

Gut microbiota and metabolic syndrome.

Symbiosis is the result of the relationship between gut microbiota and human surfaces; in fact, it regulates many functions such as metabolic and protective ones. It is widely known that any changes in the microbes in gut microbiota (dysbiosis) and the regulation of mucosal and systemic host's immunity have been linked to different diseases such as metabolic syndromes and associated disorders. Recent studies report an aberrant gut microbiota and an alteration of gut microbial metabolic activities in obese subjects, with an important influence of a number of human physiological functions.

Microscopic colitis.

Microscopic colitis may be defined as a clinical syndrome, of unknown etiology, consisting of chronic watery diarrhea, with no alterations in the large bowel at the endoscopic and radiologic evaluation. Therefore, a definitive diagnosis is only possible by histological analysis. The epidemiological impact of this disease has become increasingly clear in the last years, with most data coming from Western countries.

Folate in gastrointestinal health and disease.

Objective: Folate has heterogeneous functions and is involved in several activities in both animal and human body. It is an important constituent of our organism, and its bioavailability is mainly dependent from the correct function of our gastrointestinal tract. Our aim is to describe what happens to folate homeostasis in gastrointestinal health and disease, analyzing the alterations of folate metabolism in some specific conditions of intestinal and liver impairment.

[Chronic hepatitis C virus infection: clinical picture and treatment possibilities].

It has been estimated that between 1.5 and 2 million people in Italy have anti-HCV antibodies. The vast majority are chronically infected with HCV and are unaware of the infection.

Individualized treatment with combination of Peg-interferon alpha 2b and ribavirin in patients infected with HCV genotype 3.

Background & Aims: The benefit of individualizing treatment for patients with genotype 3 HCV infection on the basis of viral clearance at week 4 (wk4-R) has not been firmly established.

Methods: Four hundred and fourteen patients received Peg-interferon alpha-2b plus 1000-1200 mg of ribavirin daily according with body weight > or <75 kg. Patients were randomized to standard 24 weeks (Std24) or to a 12 or 36 weeks variable treatment duration (Var12/36).

Patterns of chronic hepatitis B in Central Italy: a cross-sectional study.

We investigated the patterns of chronic hepatitis B virus (HBV)-related disease in a large cohort of HBsAg-positive patients, in Central Italy, by collecting a screening form with demographic, clinical and laboratory data. Overall, 737 HBsAg-positive cases were included (70% male; median age 52 years): 30% were inactive HBsAg carriers, 51% had chronic hepatitis B (CHB) and 19% had HBV-related cirrhosis. Patients from non-European Union (EU) countries (n = 65) were significantly younger, had a higher prevalence of HBeAg-positive infection and hepatitis delta virus (HDV) co-infection than patients of Italian origin.

Late development of splenic artery aneurysm after orthotopic liver transplantation: a case report.

Splenic artery aneurysm (SAA) is a rare complication after orthotopic liver transplantation (OLT). Although SAAs are often incidental findings, in some cases they present with signs and symptoms of abdominal mass or intra-abdominal hemorrhage. The diagnosis requires Doppler ultrasound and confirmation with computed tomography, magnetic resonance, or angiography.

Orthotopic liver transplantation after successful treatment with anti-CD20 monoclonal antibody (rituximab) for severe steroid-resistant autoimmune hemolytic anemia: a case report.

Chronic hepatitis C virus (HCV) infection has been associated with a wide number of immunologic disorders, ranging from clinically silent laboratory abnormalities (eg, autoantibody positivity) to severe systemic diseases (eg, cryoglobulinemic vasculitis). Autoimmune hemolytic anemia (AIHA), due to the production of antibodies against erythrocyte membrane antigens, is an uncommon extrahepatic manifestation in the setting of chronic hepatitis C. Herein we have reported the case of a 57-year-old woman with decompensated HCV-related cirrhosis awaiting orthotopic liver transplantation (OLT) who experienced severe AIHA.

Sustained virological responses following standard anti-viral therapy in decompensated HCV-infected cirrhotic patients.

Background: Little data is available about predictors of sustained virological response (SVR) during anti-viral therapy of patients with decompensated HCV cirrhosis.

Aims: To determine whether rapid and early virological responses (RVR and EVR) could predict SVR and help optimize treatment in these patients.

Methods: A total of 94 cirrhotics underwent treatment with peg-interferon alfa-2b (1.

Donor-recipient MELD-based match in a patient who required three liver grafts in the era of nonstandard donors: case report.

In recent studies, nonstandard donors and high Model for End-stage Liver Disease (MELD) values have been indicated as risk factors for both graft survival and patient survival. A recent debate concerns which donor and recipient match guarantees the best results in terms of early and late survival. To emphasize the role of the donor-recipient match, we have reported herein a complex case of a patient who changed his preoperative risk status, being transplanted three times using donors of different risk levels.
