Article Synopsis
  • - Sarcopenia, a condition involving muscle loss, is common in men with liver cirrhosis and has negative effects on health, including increasing the risk of hepatic encephalopathy (HE); androgen receptor agonists (ARAs) like LPCN 1148 show potential to address these issues but their effectiveness and safety in this demographic were previously unclear.
  • - In a phase 2 trial, men with cirrhosis and sarcopenia were given either LPCN 1148 or placebo for 24 weeks, with results indicating that those taking LPCN 1148 had a significant increase in muscle mass (measured by CT scans) and experienced fewer episodes of serious HE compared to the placebo group.

Article Synopsis
  • A study was conducted to analyze overall survival (OS) in patients with unresectable hepatocellular carcinoma treated with selective internal radiation therapy using Yttrium-90 microspheres from 2004 to 2017.
  • The study involved 226 patients, finding that median OS was 16.6 months, influenced by factors like previous treatments, tumor characteristics, and whether a liver transplant was performed.
  • Adverse events were reported in 40.3% of patients, with serious complications like grade 4 bilirubin increases affecting some patients, highlighting the risks associated with the treatment.

Background & Aims: Non-alcoholic steatohepatitis is a leading cause of end-stage liver disease. Hepatic steatosis and lipotoxicity cause chronic necroinflammation and direct hepatocellular injury resulting in cirrhosis, end-stage liver disease and hepatocellular carcinoma. Emricasan is a pan-caspase inhibitor that inhibits excessive apoptosis and inflammation; it has also been shown to decrease portal pressure and improve synthetic function in mice with carbon tetrachloride-induced cirrhosis.

Background And Aims: Perceived stress and mindfulness can impact medical decision-making in both patients and clinicians. The aim of this study was to conduct a cross-sectional evaluation of the relationships between stress, mindfulness, self-regulation, perceptions of treatment conversations, and decision-making preferences among clinicians. Also, perceptions of treatment conversations and decision-making preferences among patients with cancer were evaluated.

Introduction: Hepatitis C virus (HCV) infection is common in patients with end-stage renal disease. We investigated the safety and efficacy of ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (r) ± dasabuvir (DSV) ± ribavirin (RBV) in 2 phase 3, open-label, multicenter studies in patients with stage 4 or 5 chronic kidney disease (CKD).

Methods: RUBY-I, Cohort 2 enrolled treatment-naïve or -experienced patients with HCV genotype (GT) 1a or 1b infection, with or without cirrhosis.

Background & Aims: Non-invasive tools for monitoring treatment response and disease progression in non-alcoholic steatohepatitis (NASH) are needed. Our objective was to evaluate the utility of magnetic resonance (MR)-based hepatic imaging measures for the assessment of liver histology in patients with NASH.

Methods: We analyzed data from patients with NASH and stage 2 or 3 fibrosis enrolled in a phase II study of selonsertib.

Unlabelled: Well-tolerated, ribavirin-free, pangenotypic hepatitis C virus (HCV) treatments for transplant recipients remain a high priority. Once-daily glecaprevir/pibrentasvir demonstrates high rates of sustained virologic response at 12 weeks posttreatment (SVR12) across all major HCV genotypes (GTs). This trial evaluated the safety and efficacy of glecaprevir/pibrentasvir for patients with chronic HCV GT1-6 infection who had received a liver or kidney transplant.

Background: Selective internal radiation therapy (SIRT) with yttrium-90 resin (Y-90 resin) microspheres has been used as a locoregional therapy for patients with unresectable hepatocellular carcinoma (HCC). We examined patient and disease characteristics that might affect survival after Y-90 resin, as well as treatment tolerability.

Methods: Data from patients with unresectable HCC treated with Y-90 resin at a single institution were reviewed retrospectively.

Article Synopsis
  • The studies assessed the effectiveness and safety of ledipasvir/sofosbuvir (LDV/SOF) with or without ribavirin (RBV) for treating chronic hepatitis C in patients who previously failed treatment.
  • The RESCUE study involved HCV mono-infected adults, while the A5348 study focused on HCV/HIV co-infected individuals, both aiming for sustained virological response (SVR) 12 weeks post-treatment.
  • Results showed an 88% SVR rate in the RESCUE study, with mostly mild side effects reported, and all participants in the A5348 study achieved SVR with no serious adverse events.

Article Synopsis
  • Hepatitis C virus (HCV) varies greatly in its types and is widespread globally, creating a need for effective treatments that work quickly across all major genotypes.
  • The study evaluated the safety and effectiveness of a combination therapy called glecaprevir/pibrentasvir, administered for either 8 or 12 weeks, in patients with specific HCV genotypes and no cirrhosis through three clinical trials.
  • Results showed high rates of sustained virologic response (SVR12)—about 98% for 8 weeks and 99.5% for 12 weeks of treatment—indicating that the treatment was highly effective in clearing the virus in patients with HCV genotypes 2, 4,

Article Synopsis
  • The study investigates the effects of selonsertib, a drug that inhibits a specific kinase, on inflammation and fibrosis in patients with nonalcoholic steatohepatitis (NASH) and liver fibrosis.
  • In a phase 2 trial, 72 patients received either selonsertib alone or with simtuzumab for 24 weeks, with assessments made through various medical imaging techniques and biopsies.
  • Results showed that selonsertib treatment led to a significant reduction in liver fibrosis stages, with improvements in liver stiffness and other health markers, while no notable differences in side effects were observed among the treatment groups.

Background & Aims: Although hepatitis C virus (HCV) infection is common in patients with end-stage renal disease, highly efficacious, well-tolerated, direct-acting antiviral regimens have not been extensively studied in this population. We investigated the safety and efficacy of ombitasvir co-formulated with paritaprevir and ritonavir, administered with dasabuvir (with or without ribavirin) in a prospective study of patients with stage 4 or 5 chronic kidney disease (CKD).

Methods: We performed a single-arm, multicenter study of treatment-naïve adults with HCV genotype 1 infection, without cirrhosis and with CKD stage 4 (estimated glomerular filtration rate, 15-30 mL/min/1.

Background: Hepatitis C virus (HCV) infection is the leading indication for liver transplantation worldwide, and interferon-containing regimens are associated with low response rates owing to treatment-limiting toxic effects in immunosuppressed liver-transplant recipients. We evaluated the interferon-free regimen of the NS5A inhibitor ombitasvir coformulated with the ritonavir-boosted protease inhibitor ABT-450 (ABT-450/r), the nonnucleoside NS5B polymerase inhibitor dasabuvir, and ribavirin in liver-transplant recipients with recurrent HCV genotype 1 infection.

Methods: We enrolled 34 liver-transplant recipients with no fibrosis or mild fibrosis, who received ombitasvir-ABT-450/r (at a once-daily dose of 25 mg of ombitasvir, 150 mg of ABT-450, and 100 mg of ritonavir), dasabuvir (250 mg twice daily), and ribavirin for 24 weeks.

Objective: Data on the nature of small-bowel tumors found or missed by capsule endoscopy (CE) are limited. The aim of this study was to review the CE findings in patients with small-bowel tumors presenting as obscure gastrointestinal (GI) bleeding.

Material And Methods: We retrospectively reviewed the medical records of the first 300 patients who underwent CE for obscure bleeding (non-diagnostic EGD and colonoscopy) at our institution.

Positive findings on capsule endoscopy (CE) often prompt a follow-up procedure with therapeutic intent. Our purpose was to review the therapeutic yield of subsequent procedural interventions based on positive CE findings. The medical records of all patients who underwent CE between June 2002 and February 2005 for obscure bleeding were retrospectively reviewed.

Very few cases of liver transplantation in patients with sickle cell disease have been reported in peer-reviewed literature. We reviewed the medical records of two patients with sickle cell disease that received liver transplantation at our institution. The first patient was a 27-year-old female who presented with encephalopathy and cholestatic jaundice with a Hemoglobin S (HbS) level of 69.
