Prevalence, Pathogenesis and Management of Anemia in Inflammatory Bowel Disease: An IG-IBD Multicenter, Prospective, and Observational Study.

Background: Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD), with a 6% to 74% prevalence and a negative impact on patient survival and quality of life, although the prevalence is apparently declining due to improved disease treatment. We aimed to investigate the prevalence, pathogenesis, and clinical correlates of anemia in Italian patients with IBD.

Methods: A multicenter, prospective, observational study, involving 28 Italian gastroenterology centers, was conducted to investigate the epidemiology and consequences of IBD-associated anemia.

Tolerability of Bowel Preparation and Colonoscopy in IBD Patients: Results From a Prospective, Single-Center, Case-Control Study.

Background: Endoscopy plays a fundamental role in the management of patients with inflammatory bowel disease (IBD). The aim of this study was to prospectively evaluate the tolerability and efficacy of bowel preparation and colonoscopy in ulcerative colitis (UC) and Crohn's disease (CD) patients compared to subjects participating in a colorectal cancer population screening program.

Methods: Consecutive enrolment of CD and UC patients and screening subjects (SS) undergoing colonoscopy.

Endoscopic ultrasound-guided radiofrequency ablation for hepatocellular carcinoma in cirrhosis: a case report test for efficacy and future perspectives.

The percutaneous approach allows for effective and safe treatment of liver lesions. But in case of subcapsular or left segments location, this approach seems to be less effective or unsafe. Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a new technique used to treat pancreatic and neuroendocrine tumors in patients unfit for surgery.

Clinical Characteristics of COVID-19 Patients With Gastrointestinal Symptoms in Northern Italy: A Single-Center Cohort Study.

Introduction: The most typical presentation of COVID-19 is an acute respiratory syndrome whose most common symptoms include fever, cough, and dyspnea. However, gastrointestinal symptoms, such as diarrhea and nausea/vomiting, are increasingly reported in patients affected by COVID-19. This study aimed to describe the prevalence and time of onset of gastrointestinal symptoms in patients affected by COVID-19 and to find potential associations between gastrointestinal symptoms and clinical outcomes.

Inflammatory bowel disease in a colorectal cancer screening population: Diagnosis and follow-up.

Background: Inflammatory bowel disease (IBD) is usually diagnosed in subjects with gastrointestinal symptoms, but may also be asymptomatic and diagnosed incidentally.

Aims: to determine the prevalence of IBD in asymptomatic adults.

Methods: we identified subjects who underwent colonoscopy between 1 September 2013 and 31 August 2019 in a regional colorectal cancer screening program with endoscopic findings suggestive of IBD, and retrieved their clinical, histological and therapeutic information.

Efficacy of a novel self-assembling peptide hemostatic gel as rescue therapy for refractory acute gastrointestinal bleeding.

Background: Acute gastrointestinal bleeding (AGIB) results in significant morbidity and mortality. Topical hemostatic products have been developed for endoscopic use to help in the management of difficult bleeding. Our aim was to demonstrate the ease of use, safety, and efficacy of PuraStat, a novel hemostat, to control AGIB.

Prognostic ability of BCLC-B Subclassification in Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization.

Unlabelled: Prognostic ability of BCLC-B Subclassification in Patients with Hepatocellular Carcinoma Undergoing Transarterial Chemoembolization Background and aims. A subclassification system for intermediate hepatocellular carcinoma (HCC) was recently proposed to optimize treatment allocation. The aim of this study was to assess the prognostic ability of that substaging proposal.

eNOS polymorphisms and clinical outcome in advanced HCC patients receiving sorafenib: final results of the ePHAS study.

Sorafenib may reduce endothelial nitric oxide synthase (eNOS) activity by inhibiting vascular endothelial growth factor receptors (VEGF-R), leading to a decrease in nitric oxide production. In the Italian multicenter ePHAS (eNOS polymorphisms in HCC and sorafenib) study, we analyzed the role of eNOS polymorphisms in relation to clinical outcome in patients with hepatocellular carcinoma (HCC) receiving sorafenib. Our retrospective study included a training cohort of 41 HCC patients and a validation cohort of 87 HCC patients, all undergoing sorafenib treatment.

Risk of hepatocellular carcinoma in relation to ABO blood type.

Background: Mortality and incidence rates of hepatocellular carcinoma (HCC) parallel the geographical distribution of hepatitis B and C viruses among the general population, however genetic factors modulate individual cancer risk.

Aims: ABO blood type, as a genetic marker, has previously been associated with the risk of several malignancies; we aimed to evaluate whether an association exists with HCC.

Methods: This is a retrospective case-control study based on ABO distribution in 194 patients with HCC, compared with 215 decompensated cirrhotics without HCC listed for liver transplantation, and 90,322 healthy blood donors.

Early diagnosis of liver cancer: an appraisal of international recommendations and future perspectives.

All Societies, AASLD, EASL, APASL and JSH, identify patients with cirrhosis as a target population for surveillance, with minor differences for additional categories of patients, such as chronic hepatitis B and hepatitis C patients with advanced fibrosis. According to AASLD, liver disease related to metabolic diseases including diabetes and obesity is a recognized target of screening, since those conditions have been causally related to HCC. All societies endorse radiological non-invasive techniques as the mainstay for early diagnosis of HCC, but discrepancies exist between Societies on the utilization of contrast-enhanced ultrasound and utilization of serum markers for surveillance and diagnosis of HCC.

Hepatocellular Carcinoma in Patients with a Sustained Response to Anti-Hepatitis C Therapy.

Hepatocellular carcinoma (HCC) is a common, life-threatening complication of longstanding infection with the hepatitis C virus (HCV), likely a consequence of the direct oncogenic activity of the virus cooperating with liver cell inflammation in transforming the liver into a mitogenic and mutagenic environment. The achievement of a sustained virological response (SVR) to interferon-based therapies has been shown to benefit the course of hepatitis C in terms of reduced rates of liver-related complications and mortality from all causes. Interestingly, while achievement of an SVR is associated with a negligible risk of developing clinical decompensation over the years, the risk of HCC is not fully abrogated following HCV clearance, but it remains the dominant complication in all SVR populations.

Predictors of survival in patients with advanced hepatocellular carcinoma who permanently discontinued sorafenib.

Unlabelled: Treatment with sorafenib of patients with advanced hepatocellular carcinoma is challenged by anticipated discontinuation due to tumor progression, liver decompensation, or adverse effects. While postprogression survival is clearly determined by the pattern of tumor progression, understanding the factors that drive prognosis in patients who discontinued sorafenib for any reason may help to improve patient management and second-line trial design. Patients consecutively admitted to three referral centers who were receiving best supportive care following permanent discontinuation of sorafenib for any reason were included.

Impact of HBV therapy on the incidence of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a frequent, long term complication of chronic infection with hepatitis B virus (HBV) with an annual incidence ranging from 2 to 5%, often independent from the histological stage of underlying liver disease and serological status. Nevertheless, HCC is more often seen in older patients in whom HBV has been asserting its pro-oncogenic properties through both indirect and direct mechanisms. In Europe, HBV-related HCC is associated with cirrhosis in most patients, whereas this is not true in Asia and Africa where the tumour is also common among carriers with mild hepatic fibrosis, probably because of the coexistence of environmental co-carcinogens (aflatoxin) and long standing infection that is often acquired perinatally.

Individualized hepatocellular carcinoma risk: the challenges for designing successful chemoprevention strategies.

Hepatocellular carcinoma (HCC) develops in the context of environmental risk factors like chronic viral hepatitis, diabetes and alcohol exposure, often associated to an increased risk of cirrhosis. Antiviral treatments that are effective to counteract hepatitis B and C may also attenuate the risk of tumor development. However, since hepatitis B-related carcinogenesis is promoted independently of the onset of cirrhosis, such antiviral treatments as nucleo(t)side analogs can promote regression of cirrhosis, prevent clinical decompensation and variceal bleeding but not HCC.

Surveillance for hepatocellular carcinoma.

The only hope for a cure from hepatocellular carcinoma (HCC) rests on early diagnosis as it can be attained through semiannual surveillance with abdominal ultrasound (US) of patients at risk. While the strategy of semiannual screening rests on the growth rate of the tumor that in cirrhotic patients takes 6 months to double its volume, on average, the noninvasive radiological diagnosis of HCC is possible in cirrhotic patients with a de novo HCC and patients with chronic hepatitis B. More recently, metabolic diseases related to insulin resistance, including diabetes and obesity, have been recognized to be causally related to HCC as well, in most patients bridging HCC to the histopathological diagnosis of non-alcoholic steatohepatitis (NASH).

The diagnostic and economic impact of contrast imaging techniques in the diagnosis of small hepatocellular carcinoma in cirrhosis.

Background: Contrast-enhanced ultrasound (CE-US), contrast CT scan and gadolinium dynamic MRI are recommended for the characterisation of liver nodules detected during surveillance of patients with cirrhosis with US.

Aim: To assess the sensitivity, specificity, diagnostic accuracy and economic impact of all possible sequential combinations of contrast imaging techniques in patients with cirrhosis with 1-2 cm liver nodules undergoing US surveillance.

Patients/methods: 64 patients with 67 de novo liver nodules (55 with a size of 1-2 cm) were consecutively examined by CE-US, CT, MRI, and a fine-needle biopsy (FNB) as diagnostic standard.
