1. Hepatic encephalopathy increases the risk for mortality and hospital readmission in decompensated cirrhotic patients: a prospective multicenter study

Author: Oliviero Riggio, Ciro Celsa, Vincenza Calvaruso, Manuela Merli, Paolo Caraceni, Sara Montagnese, Vincenzina Mora, Martina Milana, Giorgio Maria Saracco, Giovanni Raimondo, Antonio Benedetti, Patrizia Burra, Rodolfo Sacco, Marcello Persico, Filippo Schepis, Erica Villa, Antonio Colecchia, Stefano Fagiuoli, Mario Pirisi, Michele Barone, Francesco Azzaroli, Giorgio Soardo, Maurizio Russello, Filomena Morisco, Sara Labanca, Anna Ludovica Fracanzani, Antonello Pietrangelo, Gabriele Di Maria, Silvia Nardelli, Lorenzo Ridola, Antonio Gasbarrini, and Calogero Cammà

Abstract: IntroductionHepatic encephalopathy (HE) affects the survival and quality of life of patients with cirrhosis. However, longitudinal data on the clinical course after hospitalization for HE are lacking. The aim was to estimate mortality and risk for hospital readmission of cirrhotic patients hospitalized for HE.MethodsWe prospectively enrolled 112 consecutive cirrhotic patients hospitalized for HE (HE group) at 25 Italian referral centers. A cohort of 256 patients hospitalized for decompensated cirrhosis without HE served as controls (no HE group). After hospitalization for HE, patients were followed-up for 12 months until death or liver transplant (LT).ResultsDuring follow-up, 34 patients (30.4%) died and 15 patients (13.4%) underwent LT in the HE group, while 60 patients (23.4%) died and 50 patients (19.5%) underwent LT in the no HE group. In the whole cohort, age (HR 1.03, 95% CI 1.01–1.06), HE (HR 1.67, 95% CI 1.08–2.56), ascites (HR 2.56, 95% CI 1.55–4.23), and sodium levels (HR 0.94, 95% CI 0.90–0.99) were significant risk factors for mortality. In the HE group, ascites (HR 5.07, 95% CI 1.39–18.49) and BMI (HR 0.86, 95% CI 0.75–0.98) were risk factors for mortality, and HE recurrence was the first cause of hospital readmission.ConclusionIn patients hospitalized for decompensated cirrhosis, HE is an independent risk factor for mortality and the most common cause of hospital readmission compared with other decompensation events. Patients hospitalized for HE should be evaluated as candidates for LT.

Author: Daniele Balducci, Claudia Quatraccioni, Luigi Maria Daretti, Michele Montori, Emanuele Bendia, Luca Maroni, and Antonio Benedetti
Subjects: black esophagus, circumferential esophageal necrosis, duodenal ulcer, upper gastrointestinal bleeding, coffee ground emesis, case report, Medicine (General), R5-920, Medical physics. Medical radiology. Nuclear medicine, R895-920
Abstract: Black esophagus or acute esophageal necrosis is characterized by circumferential black discoloration of the distal esophageal mucosa. It is a rare condition with a multifactorial pathogenesis, and its most common clinical presentation is acute upper gastrointestinal bleeding. It usually affects elderly patients with multiple comorbidities and is associated with a high mortality rate. This is a case report of a 90-year-old man with multiple comorbidities, including diabetes mellitus, atrial fibrillation with complete atrioventricular block, and a history of ischemic stroke, who presented to the emergency department for a syncopal episode followed by coffee ground emesis. Thoraco-abdominal computer tomography showed thickening of the distal esophagus and ruled out major complications such as perforation. The following esophagogastroduodenoscopy showed black circumferential necrosis of the mid and distal esophagus. Multiple irregular ulcers with black necrotic areas were also present in the bulb and second duodenal portion. During the hospitalization, the patient was treated with PPI, NPO nutrition, and broad-spectrum antibiotics with benefits. Two months later, the patient returned to the emergency department due to a new episode of hematemesis with endoscopic evidence of esophageal stricture without necrosis and recurrence of duodenal ulcers. After a few days, the patient died due to worsening of the underlying comorbidities. A black esophagus is associated with duodenal ulcers, which may recur and are possibly due to a common ischemic origin. In this case report, we explore the potential link between black esophagus and duodenal ulcers, discussing the underlying mechanisms and relevant literature supporting this association.

Subjects: Gastro-intestinal complications (GICs) in allogeneic hematopoietic stem cell transplant (allo-HSCT), graft-versus-host-disease (GVHD), mucositis, endoscopy, intestinal histology, Diseases of the blood and blood-forming organs, RC633-647.5
Abstract: Gastrointestinal complications (GICs) represent the major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Differential diagnosis of GICs is of paramount importance since early and reliable identification of graft-versus-host disease (GVHD) is essential for a correct management of the patients. The aim of the present retrospective study was to evaluate the occurrence of GICs after allo-HSCT and to assess the diagnostic performance of a quick endoscopic and histological assessment in the differential diagnosis between GVHD and other GI conditions. Between January 2015 and August 2019, 122 consecutive patients receiving an allo-HSCT were managed by an interdisciplinary team, supported by a dedicated endoscopic service. Clinical, therapeutic, endoscopic and histological data were analyzed for each patient. Collectively, 94 of the patients developed GICs (77%). A moderate–severe mucositis was the most frequent complication, occurring in 79 patients (84%). Acute GI-GVHD was diagnosed in 35 patients (37% of whom with GICs) and 19 of them with a moderate–severe grade. Infective acute colitis developed in eight patients, mainly due to Clostridium difficile (CD) and Cytomegalovirus infections (8.5%). Rectal biopsy showed the highest sensitivity and specificity (80% and 100%, respectively). However, when biopsy procedures were guided by symptoms and performed on apparently intact mucosa, upper histology also provided a high negative predictive value (80%). Our multidisciplinary approach with a quick endoscopic/histologic investigation in the patients receiving an allo-HSCT and who suffered GICs could improve diagnostic and therapeutic management in this challenging setting.

Subjects: cytotoxic t-lymphocyte antigen 4, programmed cell death 1, programmed cell death-ligand 1, immune checkpoint, gastrointestinal toxicity, Internal medicine, RC31-1245
Abstract: Immune checkpoint inhibitors, such as cytotoxic T-lymphocyte antigen 4 inhibitors, programmed cell death 1 inhibitors and programmed cell death-ligand 1 inhibitors, have recently emerged as novel drugs in the anti-cancer therapy. Their use in different types of advanced cancer has shown good results and an increase in survival rates. However, immune-related adverse events (irAEs) are frequent and often require special care. IrAEs may affect all the organs, but they are most commonly seen in skin, lungs, endocrine glands and in the gastrointestinal tract where small bowel, colon, the liver and/or the pancreas can be involved. Despite being usually mild and self-resolving, irAEs may present in severe and life-threatening forms, causing the withdrawal of anti-cancer therapy. IrAEs, therefore, represent a challenging condition to manage that often requires the cooperation between the oncologists and the gastroenterologists in order to identify and treat them adequately.

5. Involvement of Autophagy in Ageing and Chronic Cholestatic Diseases

Author: Claudio Pinto, Elisabetta Ninfole, Antonio Benedetti, Marco Marzioni, and Luca Maroni
Subjects: autophagy, ageing, cholestasis, FXR, Rubicon, cholangiopathies, Cytology, QH573-671
Abstract: Autophagy is a “housekeeping” lysosomal degradation process involved in numerous physiological and pathological processes in all eukaryotic cells. The dysregulation of hepatic autophagy has been described in several conditions, from obesity to diabetes and cholestatic disease. We review the role of autophagy, focusing on age-related cholestatic diseases, and discuss its therapeutic potential and the molecular targets identified to date. The accumulation of toxic BAs is the main cause of cell damage in cholestasis patients. BAs and their receptor, FXR, have been implicated in the regulation of hepatic autophagy. The mechanisms by which cholestasis induces liver damage include mitochondrial dysfunction, oxidative stress and ER stress, which lead to cell death and ultimately to liver fibrosis as a compensatory mechanism to reduce the damage. The stimulation of autophagy seems to ameliorate the liver damage. Autophagic activity decreases with age in several species, whereas its basic extends lifespan in animals, suggesting that it is one of the convergent mechanisms of several longevity pathways. No strategies aimed at inducing autophagy have yet been tested in cholestasis patients. However, its stimulation can be viewed as a novel therapeutic strategy that may reduce ageing-dependent liver deterioration and also mitigate hepatic steatosis.

6. Aging-Related Molecular Pathways in Chronic Cholestatic Conditions

Author: Claudio Pinto, Elisabetta Ninfole, Antonio Benedetti, Luca Maroni, and Marco Marzioni
Subjects: aging, PSC, PBC, senescence, therapeutics, inflammation, Medicine (General), R5-920
Abstract: Aging is commonly defined as the time-dependent functional decline of organs and tissues. Average life expectancy has increased considerably over the past century and is estimated to increase even further, consequently also the interest in understanding the aging processes. Although aging is not a disease, it is the major risk factor for the development of many chronic diseases. Pathologies, such as Primary Biliary Cholangitis (PBC) and Primary Sclerosing Cholangitis (PSC) are cholestatic liver diseases characterized by chronic inflammation, biliary damage and ultimately liver fibrosis, targeting specifically cholangiocytes. To date, the influence of aging in these biliary diseases is not fully understood. Currently, liver transplantation is the only solution because of lacking in efficiently therapies. Although liver cells have a high regenerative capacity, they undergo extensive molecular changes in response to aging. Following time-dependent damage induced by aging, the cells initially activate protective compensatory processes that, if hyperstimulated, can lead to the decline of regenerative ability and the development of pathologies. Recent studies have introduced novel therapeutic tools for cholangiopathies that have showed to have promising potential as novel therapies for PSC and PBC and for the development of new drugs. The recent advancements in understanding of molecular aging have undoubtedly the potential to unveil new pathways for selective drug treatments, but further studies are needed to deepen their knowledge.

7. Gut–Liver Axis and Inflammasome Activation in Cholangiocyte Pathophysiology

Author: Luca Maroni, Elisabetta Ninfole, Claudio Pinto, Antonio Benedetti, and Marco Marzioni
Subjects: inflammasome, nlrp3, cholangiocyte, gut–liver axis, Cytology, QH573-671
Abstract: The Nlrp3 inflammasome is a multiprotein complex activated by a number of bacterial products or danger signals and is involved in the regulation of inflammatory processes through caspase-1 activation. The Nlrp3 is expressed in immune cells but also in hepatocytes and cholangiocytes, where it appears to be involved in regulation of biliary damage, epithelial barrier integrity and development of fibrosis. Activation of the pathways of innate immunity is crucial in the pathophysiology of hepatobiliary diseases, given the strong link between the gut and the liver. The liver secretes bile acids, which influence the bacterial composition of the gut microbiota and, in turn, are heavily modified by microbial metabolism. Alterations of this balance, as for the development of dysbiosis, may deeply influence the composition of the bacterial products that reach the liver and are able to activate a number of intracellular pathways. This alteration may be particularly important in the pathogenesis of cholangiopathies and, in particular, of primary sclerosing cholangitis, given its strong association with inflammatory bowel disease. In the present review, we summarize current knowledge on the gut−liver axis in cholangiopathies and discuss the role of Nlrp3 inflammasome activation in cholestatic conditions.

Abstract: NAFLD is the most common liver disease worldwide but it is the potential evolution to NASH and eventually to hepatocellular carcinoma (HCC), even in the absence of cirrhosis, that makes NAFLD of such clinical importance.we aimed to create a mouse model reproducing the pathological spectrum of NAFLD and to investigate the role of possible co-factors in promoting HCC.mice were treated with a choline-deficient L-amino-acid-defined-diet (CDAA) or its control (CSAA diet) and subjected to a low-dose i.p. injection of CCl4 or vehicle. Insulin resistance was measured by the euglycemic-hyperinsulinemic clamp method. Steatosis, fibrosis and HCC were evaluated by histological and molecular analysis.CDAA-treated mice showed peripheral insulin resistance at 1 month. At 1-3 months, extensive steatosis and fibrosis were observed in CDAA and CDAA+CCl4 groups. At 6 months, equal increase in steatosis and fibrosis was observed between the two groups, together with the appearance of tumor. At 9 months of treatment, the 100% of CDAA+CCl4 treated mice revealed tumor versus 40% of CDAA mice. Insulin-like Growth Factor-2 (IGF-2) and Osteopontin (SPP-1) were increased in CDAA mice versus CSAA. Furthermore, Immunostaining for p-AKT, p-c-Myc and Glypican-3 revealed increased positivity in the tumors.the CDAA model promotes the development of HCC from NAFLD-NASH in the presence of insulin resistance but in the absence of cirrhosis. Since this condition is increasingly recognized in humans, our study provides a model that may help understanding mechanisms of carcinogenesis in NAFLD.

12. Standardized right artery first approach during laparoscopic pancreaticoduodenectomy for periampullary neoplasms: technical aspects and perioperative outcomes

Author: Michele Mazzola, Alessandro Giani, Camillo Leonardo Bertoglio, Pietro Carnevali, Paolo De Martini, Antonio Benedetti, Irene Giusti, Carmelo Magistro, and Giovanni Ferrari
Subjects: Surgery
Abstract: The most debated aspects of laparoscopic pancreaticoduodenectomy (LPD) concern the dissection of the pancreas from the surrounding vessels and the achievement of adequate resection margins, especially in patients with pancreatic cancer.Data of consecutive patients undergoing LPD with right artery first approach from September 2020 to September 2021 for periampullary neoplasms (pancreatic, ampullary, duodenal, distal common biliary duct) were prospectively collected and retrospectively analyzed. The overall cohort was divided into two groups: patients affected by pancreatic carcinoma (PC) and patients affected by other periampullary neoplasms (OP). Surgical and postoperative outcomes between PC and OP were compared.Thirty-one patients (15 PC and 16 OP) were selected. No difference was found between PC and OP in terms of baseline characteristics. Median resection time and overall surgical time of the entire cohort were 275 min and 530 min, respectively, without difference between the groups (p = 0.599 and 0.052, respectively). Blood loss was similar between the groups, being 350 ml in PC and 325 ml in OP (p = 0.762). One patient (3.2%) was converted to laparotomy. No difference was found between the groups in terms of pathological outcomes. Median number of retrieved lymph nodes was 17. The majority of the patients (83.9%) received an R0 resection (73.3% and 93.7% in PC and OP, respectively; p = 0.172). Postoperative surgical outcomes did not differ between the groups, excepting for overall complication rate that was higher in the OP group (26.7% vs 68.7% in PC and OP, respectively; p = 0.032).Standardized right artery first approach during LPD was feasible and did not show worse surgical and postoperative outcomes in patients with pancreatic cancer as compared to those affected by other periampullary neoplasms, except for a higher rate of minor complications.

Abstract: Inflammatory Bowel Disease (IBD) patients on biological therapy are receiving vaccines against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). However, it is unclear if IBD therapy could influence the response to this vaccine. In a case-control study, we assessed the antibody profiling after anti-SARS-CoV-2 BNT162b2 vaccine in IBD patients on biological therapy.We analyzed seroprevalence and antibody titer, after 14 weeks from the first BNT162b2 vaccine dose, in IBD patients on biological therapy and Health Care Workers (HCWs). In IBD patients, medical history and disease data were recorded.Eighty-two subjects were enrolled in this study. Among them, 40 were IBD patients on biological therapy and 42 were HCWs. All subjects developed an IgG anti-Spike antibody titer above the cut-off. IBD patients on biological therapy developed a lower antibody titer than HCWs (P0.00001). No differences were reported in patients who received at least one dose of the vaccine within a period of 7 days from the last biological drug administration, compared to all other IBD patients. A difference was found between patients who were on concomitant immunosuppressive therapy and patients on sole biological therapy (P = 0.0287). Patients with presence of any sign of disease activity (clinical, endoscopic or laboratory) showed a higher development of antibody titer compared to those in complete disease remission (P = 0,0468).Our data indicate that in IBD patients, treatment with biological therapies do not affect the seroprevalence but leads to a lower antibody titer development after anti-SARS-CoV-2 BNT162b2 vaccine.

Abstract: Purpose No consensus exists on the resection extent needed to ensure oncological safety in gastrectomy for gastric adenocarcinoma (GAC). This study aims to assess the impact of margin adequacy according to Japanese Gastric Cancer Association (JGCA) guidelines on overall survival (OS). Patients and Methods Patients who underwent surgery for stage I–III GAC at our institution between 2010 and 2017 were included. Margin adequacy according to JGCA, National Comprehensive Cancer Network (NCCN), and European Society for Medical Oncology (ESMO) guidelines was assessed, and their predictive value on OS was evaluated with Harrell’s C-index. Patients were analyzed according to their margins’ adherence to JGCA guidelines, and a propensity score matching (PSM) was run. Indication to either total gastrectomy (TG) or distal gastrectomy (DG) according to each guideline was also assessed. Results A total of 279 patients were included, of whom 220 (79%) underwent DG. Adequate margins according to JGCA were obtained in 209 patients (75%). On multivariate analysis, JGCA margin adequacy was independently associated with OS, together with American Society of Anesthesiologist class, neoadjuvant chemotherapy, lymphadenectomy extent, R0 resection, and postoperative N stage. After PSM, patients with JGCA adequate margins showed better OS, recurrence-free survival (RFS), and local RFS than patients with JGCA inadequate margins. For 220 DG, JGCA guidelines would have recommended TG in 25 patients (11%), NCCN in 30 (14%), and ESMO in 90 (41%) (p < 0.001). Conclusion Adequacy of surgical resection margins to JGCA guidelines leads to improved survival outcomes and allows for a more organ-preserving approach than Western guidelines.

Abstract: Cholangiocarcinoma (CCA) is a malignant tumour of the biliary system that originates from the neoplastic transformation of cholangiocytes. CCA is characterized by late diagnosis and poor outcome, with surgery considered as the last option for management. Autophagy is a physiological lysosomal degradation process, essential for cellular homeostasis and ubiquitous in all eukaryotic cells. Several studies have reported a potential involvement of autophagy in cancer, but it remains unclear whether activation of this process represents a survival mechanism of cancer cells. In the present review, we examine the autophagic process and summarize the current knowledge about the involvement of autophagy in the progression of cancer. The link between autophagy and chemoresistance and the use of autophagic markers in diagnosis are also considered in detail. Preliminary evidence shows that the combination of autophagy modulators (activators or inhibitors) with conventional chemotherapeutic agents offers a possible treatment option against signalling pathways that are hyperactivated or altered in CCA. In vitro evidence suggests that combination of chemotherapy agents, such as cisplatin, under activation or inhibition of autophagic processes, in two different CCA cell lines, may improve chemosensitivity and reduce cell survival, respectively. A deeper understanding of these pathways, in both cancer and non-cancer cells, could unveil possible therapeutic targets to treat CCA patients.

25. Biliary granulomatous peritoneal reaction as consequence of cholecystectomy: a case report and a revision of the literature

Author: Giuseppe Tarantino, Denise Menghini, Maria Eva Argenziano, Miriam Palmieri, Alessandra Mandolesi, Enrico Dalla Bona, Antonio Benedetti, Mario Guerrieri, and Maria Giovanna Danieli
Abstract: Introduction: Bile or gallstone spillage during laparoscopic cholecystectomy occurs in 13 to 40% of cases of surgical dissection and extraction of very inflamed gallbladder with friable or gangrenous walls. Case presentation: We present a case of a patient who developed this rare complication after a difficult cholecystectomy for acute-on-chronic cholecystitis. Our patient, after about 2 years from the surgery, in the follow-up imaging studies, showed multiple nodules disseminated in the peritoneal cavity suggestive for malignancy both on abdomen computer tomography scan and on positron emission tomography. Thus, laparoscopic nodulectomy, lastly allowed histologic diagnosis of biliary peritoneal granulomatous reaction. Even if benign assessment of nodules’ nature, these lesions showed a progressive trend in increasing over the time in number and dimensions. We performed PubMed research of all cases reported in literature, to examine the cases features and to compare our findings with other clinical experiences reported by eleven international canters. Many patients were completely asymptomatic; as an occasional finding mimicking peritoneal seeding, further assessment to define the benign nature of these nodules were performed, so they underwent surgical treatment.In conclusion, development of multiple abdominal nodules resulting from a foreign-body granulomatous reaction to bile/gallstones is a quite rare event after laparoscopic cholecystectomy, but we believe it should be seriously considered in patients undergone complicated surgical procedures on biliary tracts.

Abstract: A major function of the intrahepatic biliary epithelium is bicarbonate excretion in bile. Recent reports indicate that budesonide, a corticosteroid with high receptor affinity and hepatic first pass clearance, increases the efficacy of ursodeoxycholic acid, a choleretic agent, in primary biliary cholangitis patients. We have previously reported that bile ducts isolated from rats treated with dexamethasone or budesonide showed an enhanced activity of the Na+/H+ exchanger isoform 1 (NHE1) and Cl−/HCO3− exchanger protein 2 (AE2) . Increasing the delivery of steroids to the liver may result in three beneficial effects: increase in the choleresis, treatment of the autoimmune or inflammatory liver injury and reduction of steroids’ systemic harmful effects. In this study, the steroid dexamethasone was loaded into nanohydrogels (or nanogels, NHs), in order to investigate corticosteroid-induced increased activities of transport processes driving bicarbonate excretion in the biliary epithelium (NHE-1 isoform) and to evaluate the effects of dexamethasone-loaded NHs (NHs/dex) on liver injury induced by experimental cholestatis. Our results showed that NHs and NHs/dex do not reduce cell viability in vitro in human cholangiocyte cell lines. Primary and immortalized human cholangiocytes treated with NHs/dex show an increase in the functional marker expression of NHE1 cholangiocytes compared to control groups. A mouse model of cholangiopathy treated with NHs/dex shows a reduction in markers of hepatocellular injury compared to control groups (NHs, dex, or sham group). In conclusion, we believe that the NHs/dex formulation is a suitable candidate to be investigated in preclinical models of cholangiopathies. Graphical abstract

Abstract: Background and Aims: Mixed cryoglobulinemia is the most common HCV extrahepatic manifestation. We aimed to prospectively evaluate the cryoglobulinemic vasculitis (CV) clinical profile after a sustained virologic response (SVR) over a medium-term to long-term period. Approach and Results: Direct-acting antiviral–treated cryoglobulinemic patients, consecutively enrolled in the multicentric Italian Platform for the Study of Viral Hepatitis Therapy cohort, were prospectively evaluated. Cumulative incidence Kaplan-Meier curves were reported for response, clinical deterioration, relapse and relapse-free survival rates. Cox regression analysis evaluated factors associated with different outcomes. A clinical response was reported in at least one follow-up point for 373 of 423 (88%) patients with CV who achieved SVR. Clinical response increased over time with a 76% improvement rate at month 12 after the end of treatment. A full complete response (FCR) was reached by 164 (38.8%) patients in at least one follow-up point. CV clinical response fluctuated, with some deterioration of the initial response in 49.6% of patients (median time of deterioration, 19months). In patients who achieved FCR and had an available follow-up (137 patients) a relapse was observed in 13% and it was transient in 66.7% of patients. The rate of patients without any deterioration was 58% and 41% at 12 and 24months, respectively. After achieving SVR, a clinical nonresponse was associated with older age and renal involvement; a clinical deterioration/relapse was associated with high pretreatment rheumatoid factor values, and FCR was inversely associated with age, neuropathy, and high cryocrit levels. Conclusion: In patients with CV, HCV eradication may not correspond to a persistent clinical improvement, and clinical response may fluctuate. This implies an attentive approach to post-SVR evaluation through prognostic factors and tailored treatment.

Abstract: Digital single-operator cholangioscopy (D-SOC) is an endoscopic procedure that is increasingly used for the management of bilio-pancreatic diseases. We aimed to investigate the efficacy and safety of D-SOC for diagnostic and therapeutic indications.This is a multicenter, prospective study(January 2016-June 2019) across eighteen tertiary centers. The primary outcome was procedural success of D-SOC. Secondary outcomes were: D-SOC visual assessment and diagnostic yield of SpyBite biopsy in cases of biliary strictures, stone clearance rate in cases of difficult biliary stones, rate of adverse events(AEs) for all indications.D-SOC was performed in 369 patients (201(54,5%) diagnostic and 168(45,5%)therapeutic). Overall, procedural success rate was achieved in 360(97,6%) patients. The sensitivity, specificity, PPV, NPV and accuracy in biliary strictures were: 88,5%, 77,3%, 83,3%, 84,1% and 83,6% for D-SOC visual impression; 80,2%, 92,6%, 95,1%, 72,5% and 84,7% for the SpyBite biopsy, respectively. For difficult biliary stones, complete duct clearance was obtained in 92,1% patients (82,1% in a single session). Overall, AEs occurred in 37(10%) cases.The grade of AEs was mild or moderate for all cases, except one which was fatal.D-SOC is effective for diagnostic and therapeutic indications.Most of the AEs were minor and managed conservatively, even though a fatal event has happened that is not negligible and should be considered before using D-SOC.

29. The role of tumor microenvironment in cholangiocarcinoma

Subjects: Oncology, Hepatology
Abstract: Cholangiocarcinoma (CCA) is an extremely aggressive neoplasia, mostly because of diagnostic delay and lack of effective therapies. CCA is typically surrounded by a peculiar microenvironment that includes abundant desmoplastic stroma and various cell types, which support and enhance CCA development. Among the tumor microenvironment (TME) cells, there are tumor infiltrating lymphocytes (TILs), such as CD8+ and CD4+ cells, Tregs, natural killers (NKs) and B lymphocytes. TILs contribute to an immunosuppressive microenvironment that leads to tumor immune escape. Dendritic cells (DCs) may lead to immunotolerance by maturation or antigen-presentation deficiency. Hepatic stellate cells (HSCs) are one of the major precursors of cancer-associated fibroblast (CAFs), which are distinguished in various subpopulations, each with different functions and interactions with other TME cells. CAFs can promote lymphangiogenesis, early lymph-node metastasis and proinflammatory environment, but they can also provide a physical and chemical barrier to protect CCA. Tumor-associated macrophages (TAMs) could be differentiated between two phenotypes, pro- and anti-inflammatory, and they may sustain invasiveness and immunosuppression. Myeloid-derived suppressor cells (MDSCs) impair cytotoxic T lymphocytes (CTLs) function, stimulating tumor proliferation and angiogenesis. Tumor-associated neutrophils (TANs) function is influenced by the TME, leading to tumor-suppressing or tumor-promoting functions. This paper aims to provide an overview of the CCA microenvironment cells, their role in tumor progression and possible correlated diagnostic, therapeutic and prognostic implications.

Abstract: Objective Arthritis is the most frequent extra-intestinal manifestation in patients with inflammatory bowel diseases (IBD). The coexistence of intestinal and articular inflammation advocates the need for a multidisciplinary management of patients with IBD-associated spondyloarthritis. Methods Consecutive IBD patients were evaluated jointly by the gastroenterologist and the rheumatologist in a combined clinic. All the patients were assessed and screened for articular involvement, disease activity and health related quality of life. After the prescription of a shared treatment, patients with spondyloarthritis were followed up for 24 months. Results Two hundred sixty-two IBD patients, including 80 who were classified as affected by spondyloarthritis according to the ASAS criteria, were included in the study. At baseline, patients with both IBD and spondyloarthritis showed worse quality of life in both the physical and mental domains. The multidisciplinary management provided a significant improvement of gastrointestinal and articular manifestations, as well as the health-related quality of life. Moreover, global and gastrointestinal-specific quality of life significantly correlated with articular disease activity. Conclusion The multidisciplinary management significantly improves both articular and gastrointestinal disease activities and the quality of life of patients with IBD-associated spondyloarthritis. An appropriate screening strategy and the integrated management of these patients should be encouraged and employed in clinical practice.

Abstract: A programme of work on continuous tablet manufacturing was completed as part of a UK based collaborative research project (REMEDIES: RE-configuring MEDIcines End-to-end Supply) to evaluate the operating space of the continuous platform with respect to material properties. Loss-in-weight (LIW) feeders are extensively used in the Continuous manufacture (CM) to deliver materials into the down-stream unit operations; therefore, control of mass-flow rate is critical for meeting drug product critical quality attributes (CQAs). The purpose of this work was to investigate statistical relationship for feeding unit operation that can be applied to new materials such that feeder configuration can be selected based on material properties, reducing the need for material intensive feeder trials. Three different particle size grades of Acetaminophen (APAP) and other typical tablet formulation excipients with divergent material properties were used to evaluate the operating space of the Compact LIW Feeder (GEA) using design of experiments. The presented results showed significant correlation between material properties, feeder configuration, process parameters and feeder operating space using Multivariate Analysis (MVA). The outcome of this study and proposed product development approach has the potential to reduce consumption of material, particularly Active Pharmaceutical Ingredients (APIs), and accelerate product and process development.

33. Cancer-Associated Fibroblasts in Cholangiocarcinoma: Current Knowledge and Possible Implications for Therapy

Author: Michele Montori, Chiara Scorzoni, Maria Eva Argenziano, Daniele Balducci, Federico De Blasio, Francesco Martini, Tiziana Buono, Antonio Benedetti, Marco Marzioni, and Luca Maroni
Subjects: General Medicine
Abstract: Cholangiocarcinoma (CCA) is an aggressive neoplasia with an increasing incidence and mortality. It is characterized by a strong desmoplastic stroma surrounding cancer cells. Cancer-associated fibroblasts (CAFs) are the main cell type of CCA stroma and they have an important role in modulating cancer microenvironments. CAFs originate from multiple lines of cells and mainly consist of fibroblasts and alpha-smooth muscle actin (α-SMA) positive myofibroblast-like cells. The continuous cross-talking between CCA cells and desmoplastic stroma is permitted by CAF biochemical signals, which modulate a number of pathways. Stromal cell-derived factor-1 expression increases CAF recruitment to the tumor reactive stroma and influences apoptotic pathways. The Bcl-2 family protein enhances susceptibility to CAF apoptosis and PDGFRβ induces fibroblast migration and stimulates tumor lymphangiogenesis. Many factors related to CAFs may influence CCA prognosis. For instance, a better prognosis is associated with IL-33 expression and low stromal IL-6 (whose secretion is stimulated by microRNA). In contrast, a worst prognosis is given by the expression of PDGF-D, podoplanin, SDF-1, α-SMA high expression, and periostin. The maturity phenotype has a prognostic relevance too. New therapeutic strategies involving CAFs are currently under study. Promising results are obtained with anti-PlGF therapy, nintedanib (BIBF1120), navitoclax, IPI-926, resveratrol, and controlled hyperthermia.

This study aimed to evaluate the impact of a multi-disciplinary approach and early anticoagulation therapy (AT) on bleeding/thrombotic events, recanalization rates and outcome of cirrhotic patients with SVT.Methods: This is a single-center, registry-based cohort study. Over 17 years, 149 SVT patients were enrolled and prospectively evaluated. Regarding cirrhotic-SVT, a pre-specified algorithm, guiding initial posology of AT and follow-up visits schedule, was performed. Major bleeding (MB), thrombotic events, functional liver scores and all cause-mortality were investigated. Efficacy of AT was evaluated by radiological imaging.Results: In cirrhotic-SVT, the incidence rate of MB was 8.4 per 100 patient-year (95% CI, 3.83â 15.97), while the incidence rate of thrombosis was 5.6 per 100 patient-year (95% CI, 2.05â 12.2). In incidental SVT treated with AT, MB incidence was 6.5 per 100 patient-year (95% CI: 2.8â 12.82), while in symptomatic SVT was 2.2 per 100 patient-year (95% CI: 0.25â 8.02). All thrombotic recurrences occurred in incidental SVT (7.7 per 100 patient-years; 95% CI, 3.71â 14.26). Overall survival was significantly higher in patients who had at least a partial recanalization (p < 0.01) and partial/total recanalization was independently associated with improved MELD score at multivariate analysis (HR 2.62, 95% CI 1.1â 6.47, p = 0.03).Conclusion: In cirrhotic SVT patients, partial or total resolution of thrombosis ameliorates liver function and is associated with higher overall survival. A multidisciplinary approach together with radiological follow-up at pre-fixed time improves patient selection and monitoring.Keywords: splanchnic vein thrombosis, cirrhosis, anticoagulant therapy, vessel recanalization, multidisciplinary approach

Abstract: Aims This is a prospective observational web-based survey aimed to assess the impact of SARS-CoV-2 pandemic onGastroenterology Units in Italy. Methods All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a 39-point multiple-choiceweb-based survey between March 30 thand April 7 th2020. Results Data of 121 hospitals from all 20 Italian regions were analyzed. Overall, 10.7 % of Gastroenterology divisions havebeen converted to COVID Units. Outpatients consultations, endoscopic and ultrasound procedures were limited to urgenciesand oncology indications in 85.1 %, 96.2 % and 72.2 % of Units, respectively, and 46.7 % of Units suspended the screeningfor colorectal cancer.In order to guarantee the ordinary follow-up of outpatients, 83/121 (68.6 %) divisions activated aremote consultancy service (63.9 % by phone, 31.3 % by email, 4.8 % by video). Overall, 112/121 (92.6 %) GI Units issued and followed a specific protocol for the management of patients with suspectedor confirmed SARS-CoV-2 infection. The 72.2 % of the staff received proper training for the use of personal protective equipment, although 45.5 % did not havesufficient devices for an adequate replacement. With regard to PPE availability, N95/FFP2-3 masks were available in 91/121 (75.2 %), surgical masks in 115/121 (95.0 %),gloves in 117/121 (96.7 %), disposable gown in 100/121 (82.6 %), hairnet in 104/121 (85.9 %), goggles in 78/121 (64.5 %)and boots in 57/121 (47.1 %) of divisions. Finally, in 41/121 GI divisions (33.9 %) there was at least one healthcare professional who got infected, in a total of 132subjects, of which 121/132 from divisions not-converted to COVID Units and 75/132 from high-prevalence areas. Conclusions Substantial changes of practice and reduction of procedures have been recorded in the entire country duringthe first wave of the pandemic. The long-term impact of such modifications is difficult to estimate but potentially very riskyfor many digestive diseases.

Abstract: Background The SARS-CoV-2 pandemic has had a huge impact on healthcare systems, resulting in many routine diagnostic procedures either being halted or postponed. Aims To evaluate whether the diagnoses of colorectal, gastric and pancreatic cancers have been impacted by the SARS-CoV-2 pandemic in Italy. Methods A survey designed to collect the number of histologically-proven diagnoses of the three cancers in gastroenterology services across Italy from January 1 to October 31 in 2017–2020. Non-parametric ANOVA for repeated measurements was applied to compare distributions by years and macro-areas. Results Compared to 2019, in 2020 gastric cancer diagnoses decreased by 15.9%, CRC by 11.9% and pancreatic by 9.9%. CRC distributions showed significant differences between all years, stomach cancer between 2018 and 2020 and 2019–2020, and pancreatic cancer only between 2017 and 2019. The 2019–2020 comparison showed fewer CRC diagnoses in the North (-13.7%), Center (-16.5%) and South (-4.1%), fewer stomach cancers in the North (-19.0%) and South (-9.4%), and fewer pancreatic cancers in the North (-14.1%) and Center (-4.7%), with an increase in the South (+12.3%). Distributions of CRC and gastric cancer were significantly different between all years in the North. Conclusions This survey highlights the concerning effects of the COVID-19 pandemic on the diagnostic yield of gastroenterology services for stomach, colorectal and pancreatic cancers in Italy.

Abstract: Objectives Gut microbiota has been widely reported to be involved in systemic inflammation through microbial translocation and T cell activation in several diseases. In this work we aimed to investigate bacterial infiltration and epithelial impairment in the gut of patients with IBD-associated SpA (SpA-IBD), as well as the relationship of microbial translocation with immune system activation and their putative role in the pathogenesis of joint inflammation in IBD patients. Methods Tight-junction proteins (TJPs) occludin and claudin-1/-4 and bacteria were assessed by real-time PCR analysis and immunohistochemical staining of the ileum. Intestinal fatty acid binding protein (I-FABP), lipopolysaccharides (LPS), soluble CD14 (sCD14), sclerostin and anti-sclerostin antibodies (anti-sclerostin-IgG) were assayed with ELISAs and peripheral mononuclear blood cells with flow cytometry. LPS and sCD14 were used in vitro to stimulate a human osteoblast cell line. Results Compared with IBD, ileal samples from SpA-IBD patients showed bacterial infiltration, epithelial damage and downregulation of TJPs. In sera, they showed higher serum levels of I-FABP, LPS, sCD14 (the latter correlating with sclerostin and anti-sclerostin-IgG) and higher CD80+/CD163+ and lower CD14+ mononuclear cells. In vitro experiments demonstrated that only the LPS and sCD14 synergic action downregulates sclerostin expression in osteoblast cells. Conclusion SpA-IBD patients are characterized by gut epithelium impairment with consequent translocation of microbial products into the bloodstream, immune system activation and an increase of specific soluble biomarkers. These findings suggest that gut dysbiosis could be involved in the pathogenesis of SpA-IBD and it could hopefully prompt the use of these biomarkers in the follow-up and management of IBD patients.

Abstract: Background: Direct-acting antivirals are highly effective for the treatment of hepatitis C virus (HCV) infection, regardless race/ethnicity. We aimed to evaluate demographic, virological and clinical data of HCV-infected migrants vs. natives consecutively enrolled in the PITER cohort. Methods: Migrants were defined by country of birth and nationality that was different from Italy. Mann-Whitney U test, Chi-squared test and multiple logistic regression were used. Results: Of 10,669 enrolled patients, 301 (2.8%) were migrants: median age 47 vs. 62 years, (p < 0.001), females 56.5% vs. 45.3%, (p < 0.001), HBsAg positivity 3.8% vs. 1.4%, (p < 0.05). Genotype 1b was prevalent in both groups, whereas genotype 4 was more prevalent in migrants (p < 0.05). Liver disease severity and sustained virologic response (SVR) were similar. A higher prevalence of comorbidities was reported for natives compared to migrants (p < 0.05). Liver disease progression cofactors (HBsAg, HIV coinfection, alcohol abuse, potential metabolic syndrome) were present in 39.1% and 47.1% (p > 0.05) of migrants and natives who eradicated HCV, respectively. Conclusion: Compared to natives, HCV-infected migrants in care have different demographics, HCV genotypes, viral coinfections and comorbidities and similar disease severity, SVR and cofactors for disease progression after HCV eradication. A periodic clinical assessment after HCV eradication in Italians and migrants with cofactors for disease progression is warranted.

Abstract: Background & aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease. Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals). Results: Single-marker association analyses found approximately 100 loci displaying P < 5 × 10-4, with the most significant being a signal within the OTUD5 gene (rs3027490; P = 4.80 × 10-6; odds ratio [OR], 1.39; 95% confidence interval [CI], 1.028-1.88; Japanese cohort). Although the transethnic meta-analysis evidenced only a suggestive signal (rs2239452, mapping within the PIM2 gene; OR, 1.17; 95% CI, 1.09-1.26; P = 9.93 × 10-8), the population-specific meta-analysis showed a genome-wide significant locus in East Asian individuals pointing to the same region (rs7059064, mapping within the GRIPAP1 gene; P = 6.2 × 10-9; OR, 1.33; 95% CI, 1.21-1.46). Indeed, rs7059064 tags a unique linkage disequilibrium block including 7 genes: TIMM17B, PQBP1, PIM2, SLC35A2, OTUD5, KCND1, and GRIPAP1, as well as a superenhancer (GH0XJ048933 within OTUD5) targeting all these genes. GH0XJ048933 is also predicted to target FOXP3, the main T-regulatory cell lineage specification factor. Consistently, OTUD5 and FOXP3 RNA levels were up-regulated in PBC case patients (1.75- and 1.64-fold, respectively). Conclusions: This work represents the first comprehensive study, to our knowledge, of the chrX contribution to the genetics of an autoimmune liver disease and shows a novel PBC-related genome-wide significant locus.

Abstract: [BACKGROUND & AIMS] Primary biliary cholangitis (PBC) is a chronic liver disease in which autoimmune destruction of the small intra-hepatic bile ducts eventually leads to cirrhosis. Many patients have inadequate response to licensed medications, motivating the search for novel therapies. Previous genome-wide association studies (GWAS) and meta-analyses (GWMA) of PBC have identified numerous risk loci for this condition, providing insight into its aetiology. We undertook the largest GWMA of PBC to date, aiming to identify additional risk loci and prioritise candidate genes for in silico drug efficacy screening. [METHODS] We combined new and existing genotype data for 10, 516 cases and 20, 772 controls from five European and two East Asian cohorts. [RESULTS] We identified 56 genome-wide significant loci (20 novel) including 46 in European, 13 in Asian, and 41 in combined cohorts; and a 57th genome-wide significant locus (also novel) in conditional analysis of the European cohorts. Candidate genes at newly identified loci include FCRL3, INAVA, PRDM1, IRF7, CCR6, CD226, and IL12RB1, each having key roles in immunity. Pathway analysis reiterated the likely importance of pattern recognition receptor and TNF signalling, Jak-STAT signalling, and differentiation of TH1 and TH17 cells in the pathogenesis of this disease. Drug efficacy screening identified several medications predicted to be therapeutic in PBC, some well-established in the treatment of other autoimmune disorders. [CONCLUSIONS] This study has identified additional risk loci for PBC, provided a hierarchy of agents that could be trialled in this condition, and emphasised the value of genetic and genomic approaches to drug discovery in complex disorders. [Lay summary] Primary biliary cholangitis (PBC) is a chronic liver disease that eventually leads to cirrhosis. In this study, we analysed genetic information from 10, 516 people with PBC and 20, 772 healthy individuals recruited in Canada, China, Italy, Japan, UK, or USA. We identified several genetic regions associated with PBC. Each of these regions contains several genes. For each region, we used diverse sources of evidence to help us choose the gene most likely to be involved in causing PBC. We used these ‘candidate genes’ to help us identify medications that are currently used for treatment of other conditions, which might also be useful for treatment of PBC., 原発性胆汁性胆管炎のゲノムワイド関連解析 --国際メタ解析による新規疾患感受性遺伝子と治療薬候補の同定--. 京都大学プレスリリース. 2021-06-28.

Abstract: Primary sclerosing cholangitis (PSC) is a biliary disease characterized by liver inflammation and death of cholangiocytes which, in turn, drive to fibrosis, cirrhosis and functional alterations of the liver. PSC is also associated with an increased risk of developing cholangiocarcinoma. To date, the etiopathogenesis of PSC is still not completely understood, although a genetic predisposition in association to environmental factors contribute to immune-mediated liver damage. The lack of such knowledge is responsible for the failure of most available therapies. At this time, many studies are evaluating potential approaches that could have a positive impact on the progression of the disease. This review aims to provide a summary of present and past therapeutic approaches for PSC.

Abstract: Background In Italy, the spread of the COVID-19 pandemic has stressed the entire healthcare system and required a huge re-organization of many Divisions, including those of Gastroenterology. Aims to assess the impact of COVID-19 pandemic on Gastroenterology Divisions across Italy. Methods All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a web-based survey. Results Data of 121 hospitals from all 20 Italian regions were analyzed. Overall, 10.7% Gastroenterology Divisions have been converted to Covid Units. Outpatients consultations, endoscopic and ultrasound procedures were limited to urgencies and oncology indications in 85.1%, 96.2% and 72.2% of Units, respectively, and 46.7% of them suspended the screening for colorectal cancer. Moreover, 72.2% of the staff received a training for use of personal protective equipment, although 45.5% did not have sufficient devices for adequate replacement. Overall, 132 healthcare workers in 41 Gastroenterology Divisions were found to be infected. Conclusion This is the first study to evaluate, at a country level, the impact of COVID-19 outbreak on Gastroenterology Divisions. Substantial changes of practice and reduction of procedures have been recorded in the entire country. The long-term impact of such modifications is difficult to estimate but potentially very risky for many digestive diseases.

Abstract: As examples of crucial interface organs gut and skin show more similarities than differences, therefore it is unsurprising that several gut pathologies have skin comorbidities, and vice versa. The relationship between gut and skin, referred as the “gut-skin axis”, is one of the most intriguing area of emerging research. However the complex interactions between skin and gut are far from to be completely elucidated, since neither mainstream gastroenterology nor dermatology research have systematically investigated the ‘gut-skin axis’. In the last years several clinical researches conducted jointly by Dermatology and Gastroenterology Unit of Department of Clinical and Molecular Sciences of Polytechnic Marche University have progressively contributed to give useful data to delineate the molecular mechanisms underlying the relationship between skin and gut. In the meantime, the improvement in the knowledge of pathogenic links between different disease involving skin and gastro-intestinal tract has contributed to increase the scientific cooperation between gastroenterologists and dermatologists, by feeding the research strands. Herein the results of several studies focusing on pathogenic relationship between gastrointestinal disorders as inflammatory bowel disease, non alcoholic fatty liver disease, helicobacter pylori infection and dermatologic disease like psoriasis, pyoderma gangrenosum, chronic spontaneous urticaria, suppurative hidradenitis and alopecia areata have been reported. Moreover results emerging from several other research lines involving gastroenterological and dermatological Unit independently, and focusing on cutaneous melanoma, wound healing, mesenchymal stem cells, and antimicrobial molecules are described.

Abstract: Interest in understanding the aging process has recently risen in the scientific community. Aging, commonly defined as the functional decline in the function of organs and tissues, is indeed the major risk factor for the development of many chronic diseases, such as cardiovascular diseases, pathologies of nervous system, or cancer. To date, the influence of aging in the pathophysiology of liver and biliary diseases is not fully understood. Although liver cells have a high regenerative capacity, hepatocytes and cholangiocytes undergo extensive molecular changes in response to aging. Following time-dependent damage induced by aging, liver cells initially activate compensatory mechanisms that, if hyperstimulated, may lead to the decline of regenerative capacity and the development of pathologies. A deeper understanding of molecular aging has undoubtedly the potential to improve the clinical management of patients, possibly unveiling new pathways for selective drug treatment.

Abstract: Background and aims Hepatitis E Virus is endemic in Europe with increasing numbers of cases in recent years, also in Italy where this phenomenon has hitherto been modest. The aim of this study was to document the clinical features/natural history of locally acquired hepatitis E in our territory and explore factors which determine adverse outcome. Methods Retrospective study of patients with locally-acquired HEV (hepatitis E virus) in Marche, Italy (2011–2019). Results 1189 patients were tested for HEV with 89 confirmed cases. 81 (6.8%) had locally acquired infection; 54 (66%) were male (mean age 55.5 years) and 32 (39.5%) had active co-morbidities. 41 cases were viraemic (all HEV-3 (HEV genotype 1,2,3,4)); acute infection was found in 79 and chronic infection in 2. Forty-five cases (55%) required admission to hospital, for a total of 785 days. 4 patients developed acute on-chronic liver failure, 6 developed acute kidney injury and 8 died: all had active comorbidities. Univariate analysis showed that bilirubin, INR, immunosuppression, cirrhosis and diabetes were associated with death. On multivariant analysis the only predictor of death was the presence of diabetes (p = 0.04). Conclusions Hepatitis E in Marche Italy is mostly locally acquired and caused by HEV-3 that impacts on the morbidity and mortality particularly for fragile patients.

Abstract: Background Recent data showed an increasing number of “autochthonous” cases of hepatitis E in Italy. Aims Analysing cases of acute hepatitis E to define frequency, clinical features, prognosis and risk factors. Methods We considered all the patients admitted to our Regional Hospital between August 2011 and September 2014, with a diagnosis of acute hepatitis; serological screening for hepatitis B, C and A viruses was performed; in the event of negative results, sera were tested for cytomegalovirus, Epstein–Barr and hepatitis E viruses. Results Among 200 patients, 66 were affected by viral infection. IgM anti-HEV was detected in 14 patients with a predominance of males (79%) with a mean age of 55. Genotype 3 of HEV was found in 8 patients. Only one patient died of acute on chronic liver failure; all others evolved favourably towards clinical remission within two months from clinical onset. Thirteen patients had had local exposure to infection and 9 reported the consumption of raw or undercooked locally produced pork. Conclusion The incidence of HEV in our cohort of patients with acute viral hepatitis is high (about 20% per year). In over 85% an autochthonous exposure to infection could be recognised, with a clear link with food habits.
