Histological improvement of fibrosis in patients with hepatitis C who achieved a 5-year sustained virological response to treatment with direct-acting antivirals.

Background: The histological improvement in liver fibrosis in patients with hepatitis C who achieved a sustained virological response (SVR) to direct-acting antiviral (DAA) treatment has not been comprehensively investigated. Therefore, we assessed the histological changes in liver fibrosis among patients with hepatitis C who underwent long-term follow-up after achieving SVR to treatment with DAA.

Methods: This retrospective study enrolled 71 patients with hepatitis C who achieved SVR to treatment with DAA.

Postoperative bleeding after percutaneous transhepatic gallbladder drainage and aspiration in patients receiving antithrombotic therapy.

This study aimed to investigate the bleeding risk associated with percutaneous transhepatic gallbladder interventions in patients with acute cholecystitis receiving antithrombotic therapy. In this retrospective study, 194 consecutive patients who underwent percutaneous transhepatic gallbladder interventions for acute cholecystitis between April 2011 and April 2021 were enrolled. Patients were sorted into four groups: no prior antithrombotic therapy, discontinued antithrombotic drugs, single antithrombotic drug continued perioperatively, and multiple antithrombotic drugs continued perioperatively.

Improved Liver Function After Sustained Virologic Response Enhanced Prognosis in Hepatitis C with Compensated Advanced Liver Fibrosis.

Background And Aim: Liver function can be improved in patients with chronic hepatitis C virus (HCV) infection who achieved sustained virologic response (SVR) with direct-acting antiviral (DAA) treatment. However, to our knowledge, the impact of liver function improvement after SVR on prognosis has not been investigated.

Methods: A total of 716 patients with chronic HCV infection and compensated advanced liver fibrosis who began receiving DAA treatment between September 2014 and August 2018 in 25 Japanese hospitals and achieved SVR were enrolled.

Incidence and risk factors of hepatocellular carcinoma in patients with hepatitis C who achieved a sustained virological response through direct-acting antiviral agents among the working population in Japan.

Background And Aim: The development of hepatocarcinogenesis after a sustained virological response (SVR) remains an important issue affecting the balance between treatment and occupational life of workers with chronic hepatitis C virus (HCV) infection in Japan. Here, we aimed to evaluate the hepatocellular carcinoma (HCC) reducing effect and risk factors for developing HCC after SVR in patients treated with direct-acting antiviral agents (DAAs) among the working population.

Methods: We studied 2579 working patients with chronic HCV infection who achieved SVR after antiviral treatment.

Prediction Model for Intrahepatic Distant Recurrence After Radiofrequency Ablation for Primary Hepatocellular Carcinoma 2 cm or Smaller.

Background: Intrahepatic hepatocellular carcinoma (HCC) has a high recurrence rate after radiofrequency ablation (RFA). However, to date, no standalone predictive factors for intrahepatic distant recurrence after curative ablation have been reported.

Aims: The aim of this study was to investigate predictive factors for intrahepatic distant recurrence after curative treatment with RFA for HCCs.

Serum growth differentiation factor 15 predicts hepatocellular carcinoma occurrence after hepatitis C virus elimination.

Background: After hepatitis C virus (HCV) elimination, patients should be followed up due to risk of hepatocellular carcinoma (HCC). Growth differentiation factor 15 (GDF15) is a cytokine induced by mitochondrial dysfunction or oxidative stress. Aim To evaluate the prognostic value of GDF15 for HCC occurrence after HCV elimination.

Prediction model for hepatocellular carcinoma occurrence in patients with hepatitis C in the era of direct-acting anti-virals.

Background: Several factors associated with hepatocellular carcinoma (HCC) occurrence after sustained virological response (SVR) in patients with hepatitis C have been reported. However, few validation studies have been performed in the era of direct-acting anti-virals (DAAs).

Aims: To develop a prediction model for HCC occurrence after DAA-mediated SVR and validate its usefulness.

Clinical course of hepatitis C virus-positive patients with decompensated liver cirrhosis in the era of direct-acting antiviral treatment.

Aim: The aim of the present study was to investigate the clinical course in hepatitis C virus (HCV)-positive patients with decompensated liver cirrhosis after direct-acting antivirals (DAAs) have been used for HCV infection.

Methods: This multicenter study prospectively analyzed a registered cohort composed of 73 HCV-positive patients with decompensated cirrhosis who attended our 11 institutions between January 2018 and July 2018. Prognoses, including changes in the liver reserve, hepatocellular carcinoma (HCC), decompensation events, and survival, were analyzed up to July 2020, as was the initiation of DAA treatment.

Clinical outcomes of direct-acting antiviral treatments for patients with hepatitis C after hepatocellular carcinoma are equivalent to interferon treatment.

Aim: It remains unclear how direct-acting antiviral (DAA) treatments influence hepatocellular carcinoma (HCC) recurrence and survival in comparison with interferon (IFN).

Methods: In total, 338 patients with chronic hepatitis C virus (HCV) infection and previous HCC treatments who initiated IFN (N = 88, IFN group) or DAA treatment (N = 250, DAA group) from January 2005 to November 2017 at 23 hospitals and achieved sustained virologic response (SVR) were analyzed. Cumulative HCC recurrence and survival rates were compared between the two groups using propensity score (PS) matching.

Therapeutic efficacy of lenvatinib in hepatocellular carcinoma patients with portal hypertension.

Aim: Preserved liver function may be an important factor affecting therapeutic efficacy in hepatocellular carcinoma patients treated with lenvatinib, but not all patients can be treated while preserving liver function. This study evaluated the therapeutic efficacy of lenvatinib in patients with poor liver function with and without portal hypertension.

Methods: This prospectively registered multicenter study analyzed 93 patients treated with lenvatinib.

Pre-existing minor variants with NS5A L31M/V-Y93H double substitution are closely linked to virologic failure with asunaprevir plus daclatasvir treatment for genotype 1b hepatitis C virus infection.

Background: L31 and Y93 in the NS5A region of the hepatitis C virus (HCV) are the most important substitution positions associated with resistance to direct-acting antiviral (DAA) treatment.

Methods: We analyzed the frequency of NS5A L31M/V and Y93/H in NS5A inhibitor-naive HCV genotype 1 patients who received asunaprevir plus daclatasvir combination treatment using a conventional sequencing method and a deep sequencing method that can distinguish a single substitution at either position and a double substitution at both positions with a 0.1% detection threshold.

Hepatocellular carcinoma occurrence does not differ between interferon-based and interferon-free treatment with liver histological assessment.

Aim: Several studies have recently reported that hepatocellular carcinoma (HCC) occurrence does not differ between hepatitis C virus patients receiving interferon (IFN)-based and IFN-free treatments considering the patients' backgrounds. However, liver fibrosis was not directly considered in these studies.

Methods: In total, 3972 patients without a history of HCC who started IFN-based or IFN-free treatment between August 2002 and April 2017 at 30 Japanese hospitals and achieved a sustained virologic response were included.

[Endoscopic treatment for gastric carcinoid tumor in a patient with type A gastritis complicated with autoimmune polyendocrine syndrome: a case report].

A 42-year-old female developed type 1 diabetes mellitus at the age of 16 years and received insulin therapy. Esophagogastroduodenoscopy revealed an atrophic change localized in the gastric body and a small, protruding gastric lesion. Biopsy revealed that this lesion was gastric neuroendocrine tumor.

Efficacy of chemotherapy for older patients with gastric cancer: a multicenter retrospective cohort study.

Background: Gastric cancer is one of the leading causes of malignant disease-related mortality, worldwide. With the use of recently developed anti-tumor agents, the prognoses of patients with unresectable gastric cancer are improving. However, the development of an aggressive treatment strategy for older patients (OPs) remains under debate due to concerns regarding treatment feasibility or patient frailty.

Predictive factors of anemia during sofosbuvir and ribavirin therapy for genotype 2 chronic hepatitis C patients.

Aim: Sofosbuvir (SOF) and ribavirin (RBV) combination therapy has improved the sustained virologic response (SVR) rate and shortened the treatment duration for patients with chronic hepatitis C virus (HCV) genotype 2 infection. Ribavirin-induced hemolytic anemia is one of the most troublesome side-effects of SOF/RBV therapy; however, factors associated with this condition have not been fully elucidated. We aimed to identify a safer way to complete treatment with SOF/RBV therapy by examining factors related to RBV-induced hemolytic anemia and identifying patients who did not develop anemia.

Incidence and risk factors of hepatocellular carcinoma change over time in patients with hepatitis C virus infection who achieved sustained virologic response.

Aim: In patients with chronic hepatitis C, hepatocellular carcinoma (HCC) occurs at a certain frequency, even if a sustained virologic response (SVR) is achieved by antiviral treatment. Old age, liver fibrosis, and high post-treatment α-fetoprotein (AFP) level are typical risk factors of post-SVR HCC. We examined whether the frequencies and factors of HCC in patients with an SVR achieved from interferon treatment changed.

Liver Fibrosis Is Associated With Corrected QT Prolongation During Ledipasvir/Sofosbuvir Treatment for Patients With Chronic Hepatitis C.

Combination treatment of ledipasvir and sofosbuvir (LDV/SOF) is first-line treatment for patients with chronic hepatitis C genotype 1 in the United States, Europe, and Japan. However, the influence of LDV/SOF on the cardiovascular system is poorly characterized. A total of 470 chronic hepatitis C patients who started LDV/SOF treatment between September 2015 and February 2016 at nine hospitals in Japan were prospectively enrolled in this study.
