Long-term Effect of the HCV Elimination With Direct-acting Antivirals on the Progression of Gastroesophageal Varices.

Background/aim: Gastroesophageal varices (GEV) hemorrhage is a serious complication that can lead to unfavorable outcomes in cirrhotic patients. However, the clinical impact of HCV elimination [sustained viral response (SVR)] by direct-acting antivirals (DAAs), particularly on the long-term effects on the endoscopic findings of GEV have not been sufficiently evaluated. This study aimed to investigate whether HCV elimination with DAA treatment suppresses the progression of GEV.

Feasibility of Double-Deployment Small-Diameter Covered Metallic Stent for Malignant Distal Biliary Obstruction (with Video).

Background/objectives: Covered self-expandable metallic stents (CSEMS) are commonly used to treat malignant distal biliary obstructions. A 10-mm CSEMS carries the risk of obstructing the pancreatic and cystic duct orifices by adhering to the bile duct; therefore, postoperative pancreatitis and cholecystitis are reported to occur at a certain frequency. We have adopted a new drainage technique for malignant distal biliary obstruction called ''double-slim SEMS stenting" (DSS), where two small-diameter CSEMS are placed side-by-side.

Hepatic arterial infusion of autologous CD34 cells for hepatitis C virus-related decompensated cirrhosis: A multicenter, open-label, exploratory randomized controlled trial.

Introduction: In this multicenter clinical study, we aimed to investigate the efficacy and safety of the transhepatic arterial administration of granulocyte-colony stimulating factor (G-CSF)-mobilized autologous peripheral blood (PB)-CD34 cells compared with standard therapy in patients with decompensated cirrhosis type C.

Methods: Patients were randomly assigned (2:1) to the CD34 cell transplant (CD34 cell) or standard-of-care (SOC) group and followed up for 52 weeks. The primary endpoints were the non-progression rate of Child-Pugh (CP) scores at 24 weeks post-enrollment and the safety of the protocol treatment.

A Low Geriatric Nutritional Risk Index Is Associated with Low Muscle Volume and a Poor Prognosis among Cirrhotic Patients.

: The geriatric nutritional risk index (GNRI) is an easily calculable index that can be determined using three common clinical variables. The GNRI is suggested to be related to sarcopenia in cirrhotic patients. However, the relationship between the GNRI and the prognosis in patients with liver cirrhosis (LC) has not been reported.

Metabolic dysfunction-associated steatotic liver disease criteria may underestimate the number of lean female nonalcoholic fatty liver disease patients with significant liver fibrosis.

Aim: It remains unclear whether the newly defined concept of metabolic dysfunction-associated steatotic liver disease (MASLD) appropriately includes patients with nonalcoholic fatty liver disease with significant liver fibrosis.

Methods: A total of 4112 patients in whom nonalcoholic fatty liver disease was diagnosed by ultrasonography during medical checkups were enrolled. We defined a fibrosis-4 index ≥1.

Association of PNPLA3 SNP With the Development of HBV-related Hepatocellular Carcinoma.

Background/aim: Concomitant nonalcoholic fatty liver disease (NAFLD)/hepatic steatosis (HS) is suggested to increase the risk of hepatocellular carcinoma (HCC) in hepatitis virus B (HBV)-infected patients. Patatin-like phospholipase domain-containing 3 (PNPLA3) rs738409 gene single-nucleotide polymorphism (SNP) is well-known to be associated with the development of NAFLD/HS; however, it is still unclear whether this SNP is related to the development of HCC in HBV-infected patients.

Patients And Methods: We investigated a total of 202 HBV-infected patients who received percutaneous liver biopsy, and simultaneously assessed biopsy-proven HS, insulin resistance, and the PNPLA3 SNP status.

Metastasis of Hepatocellular Carcinoma in the Pouch of Douglas Successfully Treated by Radiation Therapy: A Case Report.

Metastasis of hepatocellular carcinoma (HCC) in the pouch of Douglas is relatively rare. A 65-year-old man with liver cirrhosis was admitted for detailed examination of a pelvic tumor. He had a previous history of ruptured HCC, and received emergent hemostasis with transcatheter arterial embolization followed by curative ablation.

Diagnosis of hepatic steatosis based on ultrasound attenuation imaging is not influenced by liver fibrosis.

Aim: Recently, a new technique using attenuation imaging (ATI) was developed to diagnose hepatic steatosis. The aim of this study was to investigate whether ATI for the evaluation of hepatic steatosis is influenced by liver fibrosis.

Methods: A total of 328 patients with chronic liver disease were enrolled to study the associations between histological hepatic steatosis or liver fibrosis and ATI findings.

Clinical Characteristics of ICI-Related Pancreatitis and Cholangitis Including Radiographic and Endoscopic Findings.

The indications for immune checkpoint inhibitors (ICIs) have expanded to include carcinomas of various organs. However, as ICI therapy expands, the management of immune-related adverse events (irAEs) has become a problem. ICI-related pancreatitis and cholangitis are relatively rare irAEs.

Modification of the ALBI-PLT Score for the Prediction of High-risk Varices.

Background/aim: A new scoring system [albumin-bilirubin-platelet (ALBI-PLT) score] was reported for identifying cirrhotic patients without high-risk varices (HRV), and patients with ALBI grade 1 (≤-2.60) and a platelet count over 150×10/l were shown to have a low risk of having HRV. The present study modified the cut-off values of the variables in the ALBI-PLT score.

Possible Alterations in Appetite-related Molecules After the Elimination of Hepatitis C Virus.

Background/aim: Recent advances in antiviral treatment have achieved a sustained viral response (SVR) in over 95% of hepatitis C virus (HCV) infections. HCV elimination is suggested to improve several lifestyle-related factors; however, few studies have focused on dietary habit-/appetite-related factors.

Patients And Methods: HCV-infected patients who received Daclatasvir/Asnaprevir (DCV/ASV) therapy were enrolled, and the changes in appetite-related molecules after antiviral therapy were assessed with a multiple cytokine-measuring system.

Association of liver stiffness and steatosis with hepatocellular carcinoma development in patients with hepatitis C virus infection who received direct-acting antiviral therapy and achieved sustained virological response.

Aim: The pathogenic process underlying the development of hepatocellular carcinoma (HCC) is not yet clear in patients with chronic hepatitis C virus who receive direct-acting antiviral therapy and achieve sustained virological response. This study investigated two risk factors for HCC in these patients; specifically, hepatic fibrosis and steatosis.

Methods: A total of 355 patients in whom hepatitis C virus was eradicated by direct-acting antiviral were evaluated.

Reduced grip strength is associated with progression of depressive status in chronic liver diseases.

Background: The causal relationship between sarcopenia and depression in chronic liver disease (CLD) patients is unclear. To elucidate these issues, we aimed to investigate the impacts of muscle strength as assessed by grip strength (GS) and muscle mass as assessed by bioelectrical impedance analysis (BIA) on the progression of depression in CLD patients (n=189, 49 cirrhotic cases, and 87 males).

Methods: The Beck Depression Inventory-2nd edition (BDI-II) was used for the evaluation of depression.

Severity of liver fibrosis using shear wave elastography is influenced by hepatic necroinflammation in chronic hepatitis patients, but not in cirrhotic patients.

Aim: Shear wave elastography (SWE) in patients with chronic liver diseases is a noninvasive useful method for the diagnosis of liver fibrosis severity, which can be an alternative to liver biopsy. However, the liver stiffness measurement using SWE can be affected by various factors including hepatic inflammation, extrahepatic cholestasis, heart failure, and underlying liver diseases. The aim of this study is to clarify the correlation between liver stiffness using SWE and hepatic necroinflammation serologically and pathologically.

A New Ultrasonographic "Fluttering Sign" for Hepatic Hemangioma.

The aim of the study described here was to clarify the diagnostic value of the fluttering sign, a new sign that characterizes hepatic hemangiomas in gray-scale ultrasonography (US). It refers to a phenomenon in which the speckled echogenicity inside the hemangioma changes continuously and seems to be moving. A total of 172 hemangiomas diagnosed with contrast-enhanced US were evaluated.

Predictors for Grip Strength Loss in Patients With Chronic Liver Diseases.

Background/aim: To elucidate factors associated with secular changes of grip strength (GS) in patients with chronic liver diseases (CLDs) (n=241, 102 males, median age=63 years, 87 liver cirrhosis cases).

Materials And Methods: ΔGS (kg/year) was defined as [GS value (second time) - GS value (first time)]/[time interval between the first and second time]. GS loss (GSL) was defined as ΔGS <0 kg/year.

Calf Circumference as a Useful Predictor of Sarcopenia in Patients With Liver Diseases.

Background/aim: To elucidate the influence of calf circumference (CC) on sarcopenia in patients with chronic liver damages (CLDs, n=525, 255 men).

Patients And Methods: Anthropometry parameters including arm circumference, arm muscle circumference, CC, arm muscle area, triceps skinfold thickness, waist circumference and body mass index were measured. Patients with both grip strength (GS) decline and skeletal muscle index (SMI) decline were diagnosed as sarcopenic.

Aim: To elucidate the common and different points between sarcopenia and frailty in chronic liver damage (CLD).

Patients And Methods: Patients with both grip strength decline and skeletal muscle index decline were regarded as sarcopenia. Frailty was defined as a syndrome in which 3 or more of the following criteria were met: i) exhaustion, ii) body weight loss, iii) slow walking speed, iv) muscle weakness, and v) low physical activity.

Close Correlation between Frailty and Depressive State in Chronic Liver Diseases.

Background And Objectives: Few data with regard to the relevance between depression and frailty in chronic liver disease (CLD) patients are currently available. We aimed to elucidate the relationship between frailty and depression as evaluated by the Beck Depression Inventory-2nd edition (BDI-II) in CLD patients ( = 340, median age = 65.0 years).

Health-Related Quality of Life and Frailty in Chronic Liver Diseases.

We sought to examine the relationship between frailty and health-related quality of life as evaluated using the 36-item Short-Form Health Survey (SF-36) questionnaire in Japanese chronic liver disease (CLD) patients ( = 341, 122 liver cirrhosis cases, median age = 66 years). Frailty was defined as a clinical syndrome in which three or more of the following criteria were met (frailty score 3, 4, or 5): unintentional body weight loss, self-reported exhaustion, muscle weakness (grip strength: <26 kg in men and <18 kg in women), slow walking speed (<1.0 m/s), and low physical activity.

Serum Zinc Level Is Associated with Frailty in Chronic Liver Diseases.

We sought to examine the serum zinc (Zn) level and frailty in patients with chronic liver diseases (CLDs, = 285, 107 liver cirrhosis cases, median age = 66 years). Frailty was defined as a clinical syndrome in which three or more of the following criteria were met (frailty score 3, 4, or 5): unintentional body weight loss, self-reported exhaustion, muscle weakness (grip strength: <26 kg in men and <18 kg in women), slow walking speed (<1.0 m/s), and low physical activity.

Possible Relevance of PNPLA3 and TLL1 Gene Polymorphisms to the Efficacy of PEG-IFN Therapy for HBV-Infected Patients.

Lifestyle changes have led to an increase in the number of patients with nonalcoholic fatty liver disease (NAFLD). However, the effects of NAFLD-associated single-nucleotide gene polymorphisms (SNPs) in HBV-infected patients have not been adequately investigated. Methods: We investigated the association of the NAFLD-related SNPs patatin-like phospholipase domain-containing protein 3 (PNPLA3; rs738409), transmembrane 6 superfamily member 2 (TM6SF2; rs58542926), 17-beta hydroxysteroid dehydrogenase 13 (HSD17B13; rs72613567, rs6834314 and rs62305723), membrane-bound O-acyltransferase domain containing 7 (MBOAT7; rs641738) and glucokinase regulatory protein (GCKR; rs1260326) with the presence of histologically proven hepatic steatosis (HS) in HBV-infected patients ( = 224).

Serum Zinc Level Grading System: A Useful Model for Composite Hepatic Events in Hepatitis C Virus-Associated Liver Cirrhosis.

We aimed to clarify the impact of the serum zinc (Zn) level grading system proposed by the Japanese society of clinical nutrition (JSCN: 80 μg/dL < serum Zn level <130 μg/dL (type A), 60 μg/dL < serum Zn level <80 μg/dL (type B), and serum Zn level <60 μg/dL (type C)) in patients with hepatitis C virus (HCV)-related liver cirrhosis (LC) on the incidence of composite hepatic events (Com-HEs) compared with Child-Pugh (C-P) classification or albumin-bilirubin (ALBI) grade. (n = 275, median age = 67 years). The Akaike information criterion (AIC) was compared among three prognostic models.
