Real-world effectiveness and safety of bulevirtide monotherapy for up to 96 weeks in patients with HDV-related cirrhosis.

Background And Aims: Bulevirtide (BLV) 2 mg/day is EMA approved for treatment of compensated chronic hepatitis due to Delta virus (HDV) infection, however real-life data in large cohorts of patients with cirrhosis are lacking.

Methods: Consecutive HDV-infected patients with cirrhosis starting BLV 2 mg/day since September 2019 were included in a European retrospective multicenter real-life study (SAVE-D). Patient characteristics before and during BLV treatment were collected.

Human colonic organoids for understanding early events of familial adenomatous polyposis pathogenesis.

Patients with familial adenomatous polyposis (FAP) harbor mutations in the APC gene and will develop adenoma and early colorectal cancer. There is no validated treatment, and animal models are not sufficient to study FAP. Our aim was to investigate the early events associated with FAP using the intestinal organoid model in a single-center study using biopsies from nonadenomatous and adenomatous colonic mucosa of FAP patients and from healthy controls (HCs).

Compartmentalized HIV-1 reservoir in intestinal monocytes/macrophages on antiretroviral therapy.

Background: The persistence of latently infected cells prevents a cure of HIV. The intestinal mucosa contains numerous target cells, and high levels of HIV-1 DNA persist in this compartment under ART. While CD4+ T cells are the best characterized reservoir of HIV-1, the role of long-lived intestinal macrophages in HIV-1 persistence on ART remains controversial.

Step-up approach for the treatment of infected necrotising pancreatitis: real life data from a single-centre experience with long-term follow-up.

Background: About 20% of patients with acute pancreatitis develop a necrotising form with a worse prognosis due to frequent appearance of organ failure(s) and/or infection of necrosis. Aims of the present study was to evaluate the "step up" approach treatment of infected necrosis in terms of: feasibility, success in resolving infection, morbidity of procedures, risk factors associated with death and long-term sequels.

Methods: In this observational retrospective monocentric study in the real life, necrotizing acute pancreatitis at the stage of infected walled-off necrosis were treated as follow: first step with drainage (radiologic and/or endoscopic-ultrasound-guided with lumen apposing metal stent); in case of failure, minimally invasive necrosectomy sessions(s) by endoscopy through the stent and/or via retroperitoneal surgery (step 2); If necessary open surgery as a third step.

Curative surgical treatment of common bile duct stones: Retrospective cohort study.

Background: In the event of symptomatic common bile duct (CBD) stones with dilated CBD, one possible curative treatment option is stone extraction through choledocotomy associated with cholecystectomy. Endoscopic treatment is only reserved for residual stones at 6 weeks. The aim of this study was to evaluate the results from laparoscopic curative surgical treatment of CBD stones with dilated CBD.

Identification of endoscopic predictors of biliary malignancy during digital cholangioscopy.

Objectives: Biliary brushings and biopsies obtained during endoscopic retrograde cholangiopancreatography (ERCP) have a low sensitivity for the diagnosis of malignant biliary strictures. While cholangioscopic analysis is useful, visual criteria have not yet been defined. The aim of this study was to identify visual criteria for the diagnosis of indeterminate biliary strictures (IDBS).

Management of anastomotic biliary stricture after liver transplantation and impact on survival.

Background: Anastomotic biliary strictures (AS) is the main surgical complication after liver transplantation. The aims of this study are to investigate the risk factors of AS, its management and its impact on overall survival and survival of the graft.

Methods: All patients who had received a liver transplantation with duct-to-duct anastomosis at Toulouse University Hospital between 2010 and 2016 were included.

Atherosclerotic Cardiovascular Events in Patients Infected With Human Immunodeficiency Virus and Hepatitis C Virus.

Background: An increased risk of cardiovascular disease (CVD) was reported in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV), without identifying factors associated with atherosclerotic CVD (ASCVD) events.

Methods: HIV-HCV coinfected patients were enrolled in the Agence Nationale de Recherches sur le Sida et les hépatites virales (ANRS) CO13 HEPAVIH nationwide cohort. Primary outcome was total ASCVD events.

Th22 cells are efficiently recruited in the gut by CCL28 as an alternative to CCL20 but do not compensate for the loss of Th17 cells in treated HIV-1-infected individuals.

Gut CD4 T cells are incompletely restored in most HIV-1-infected individuals on antiretroviral therapy, notably Th17 cells, a key subset in mucosal homeostasis. By contrast, gut Th22 cells are usually restored at normal frequencies. Th22 cells display a CCR6CCR10 phenotype and could thus respond to CCL20- and CCL28-mediated chemotaxis, while Th17 cells, which express CCR6 but not CCR10, depend on CCL20.

Liver stiffness and fibrosis-4 alone better predict liver events compared with aspartate aminotransferase to platelet ratio index in a cohort of human immunodeficiency virus and hepatitis C virus co-infected patients from ANRS CO13 HEPAVIH cohort.

Objectives: HIV/hepatitis C virus (HCV) co-infection leads to major complications, and noninvasive markers developed to stage liver fibrosis could be used as prognostic markers. We aimed to compare the performances of liver stiffness (LS), fibrosis-4 (FIB-4), and aspartate aminotransferase to platelet ratio index (APRI) to predict liver-related events in HIV/HCV co-infected patients.

Patients And Methods: HIV/HCV co-infected patients from the ANRS CO13 HEPAVIH cohort were included if they had LS, FIB-4, and APRI measurements done in a window of 3 months.

Factors associated with non-AIDS-defining cancers and non HCV-liver related cancers in HIV/HCV-coinfected patients- ANRS-CO13 HEPAVIH cohort.

Compared to the general population, HIV-infected patients are at higher risk of developing non-AIDS-defining cancers. Chronic HCV infection has also been associated with a higher risk than that of the general population of developing cancers other than hepatocarcinoma. Evaluation of the impact of HCV-related factors on non-AIDS-defining and non HCV-liver (NANL) related cancers among HIV/HCV co-infected patients are scarce.

Complete endoscopic sphincterotomy with vs. without large-balloon dilation for the removal of large bile duct stones: randomized multicenter study.

 Endoscopic sphincterotomy plus large-balloon dilation (ES-LBD) has been reported as an alternative to endoscopic sphincterotomy for the removal of bile duct stones. This multicenter study compared complete endoscopic sphincterotomy with vs. without large-balloon dilation for the removal of large bile duct stones.

Impact of chromoscopy on adenoma detection in patients with Lynch syndrome: a prospective, multicenter, blinded, tandem colonoscopy study.

Objectives: In Lynch syndrome, flat and diminutive adenomas are particularly prone to malignant transformation, but they can be missed by standard colonoscopy. It is not known whether chromocolonoscopy is able to detect more adenomas than standard colonoscopy in patients with Lynch syndrome.

Methods: We conducted a prospective, multicenter, randomized trial to compare standard colonoscopy with standard colonoscopy followed by pancolonic chromoscopy with indigo carmine in patients with a proven germline mutation in a mismatch-repair gene related to Lynch syndrome and who were undergoing screening or surveillance colonoscopy.

Telaprevir- and boceprevir-based tritherapies in real practice for F3-F4 pretreated hepatitis C virus patients.

Aim: To assess, in a routine practice setting, the sustained virologic response (SVR) to telaprevir (TPV) or boceprevir (BOC) in hepatitis C virus (HCV) null-responders or relapsers with severe liver fibrosis.

Methods: One hundred twenty-five patients were treated prospectively for 48 wk with TPV or BOC + pegylated-interferon (peg-INF) α2a + ribavirin (PR) according to standard treatment schedules without randomization. These patients were treated in routine practice settings in 10 public or private health care centers, and the data were prospectively collected.

Albumin dialysis with a noncell artificial liver support device in patients with acute liver failure: a randomized, controlled trial.

Background: Albumin dialysis with the Molecular Adsorbent Recirculating System (MARS) (Gambro, Lund, Sweden), a noncell artificial liver support device, may be beneficial in acute liver failure (ALF).

Objective: To determine whether MARS improves survival in ALF.

Design: Randomized, controlled trial.

Impact of molecular adsorbent recirculating system on renal recovery in type-1 hepatorenal syndrome patients with chronic liver failure.

Background And Aim: Liver transplantation remains the best option for treating type-1 hepatorenal syndrome (HRS1). The aim of this retrospective study was to determine whether the molecular adsorbent recirculation system (MARS) can improve renal function in HRS1 patients.

Methods: Thirty-two patients with chronic liver disease and HRS1 were treated by MARS sessions which were performed every other day.

Simplified identification of Lynch syndrome: a prospective, multicenter study.

Background: Recommended strategies to screen for Lynch syndrome in colorectal cancer are not applied in daily practice and most of Lynch cases remain undiagnosed.

Aims: We investigated in routine conditions a strategy that uses simplified clinical criteria plus detection of MisMatch Repair deficiency in tumours to identify Lynch carriers.

Methods: Colorectal cancer patients that met at least one of three clinical criteria were included: (1) colorectal cancer before 50 years, (2) personal history of colorectal or endometrial cancer, (3) first-degree relative history of colorectal or endometrial cancer.

Insulin resistance is associated with a higher risk of hepatocellular carcinoma in cirrhotic HIV/HCV-co-infected patients: results from ANRS CO13 HEPAVIH.

Background & Aims: Compared to HCV-mono-infected patients, hepatocellular carcinoma (HCC) occurs at younger age in HIV/HCV-co-infected patients, is markedly more advanced at diagnosis, is less amenable to curative treatment, and has a more severe outcome. The aim of this study was to identify factors predictive of HCC occurrence in a large cohort of HIV/HCV-co-infected patients with cirrhosis.

Methods: This study involved 244 HIV/HCV-co-infected patients included in the ANRS CO13 HEPAVIH cohort, who had HCV-related cirrhosis (clinically or histologically proven cirrhosis, or liver stiffness ≥12.

Altered CD4+ T cell homing to the gut impairs mucosal immune reconstitution in treated HIV-infected individuals.

Depletion of CD4+ T cells from the gut occurs rapidly during acute HIV-1 infection. This has been linked to systemic inflammation and disease progression as a result of translocation of microbial products from the gut lumen into the bloodstream. Combined antiretroviral therapy (cART) substantially restores CD4+ T cell numbers in peripheral blood, but the gut compartment remains largely depleted of such cells for poorly understood reasons.

Influence of pre-analytical conditions on plasma ribavirin concentrations.

Ribavirin (CAS 66510-90-5) associated to peginterferon (CAS 99210-65-8) is the current standard treatment for chronic hepatitis C. Exposure to ribavirin influences the virological response and anemia. Therefore monitoring plasma concentration of ribavirin is a useful tool for individualizing ribavirin dosing regimens.

The French national prospective cohort of patients co-infected with HIV and HCV (ANRS CO13 HEPAVIH): early findings, 2006-2010.

Background: In France, it is estimated that 24% of HIV-infected patients are also infected with HCV. Longitudinal studies addressing clinical and public health questions related to HIV-HCV co-infection (HIV-HCV clinical progression and its determinants including genetic dimension, patients' experience with these two diseases and their treatments) are limited. The ANRS CO 13 HEPAVIH cohort was set up to explore these critical questions.

Hepatic steatosis in patients with chronic hepatitis C virus genotype 2 or 3 does not affect viral response in patients treated with peginterferon alpha-2a (40KD) (PEGASYS) plus ribavirin (COPEGUS) for 16 or 24 weeks.

Background: Hepatic steatosis is common in patients infected with hepatitis C virus (HCV). The effect of steatosis on anti-HCV therapy efficacy is unclear.

Methods: We studied host and viral factors associated with steatosis and the effect of steatosis on treatment efficacy using the database of a large prospective trial in patients with HCV genotypes 2 and 3.
