AIM To elucidate influencing factors of treatment response, then tolvaptan has been approved in Japan for liquid retention. METHODS We herein conducted this study to clarify the influencing factors in 40 patients with decompensated liver cirrhosis complicated by liquid retention. Tolvaptan was administered at a dosage of 7.5 mg once a day for patients(More)
Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic non-viral liver disease. Activation of macrophages and hepatic stellate cells is a critical step that promotes liver fibrosis. We aimed to explore the feasibility of interleukin-34 (IL-34), a key regulator of macrophages, as a fibrosis marker in patients with NAFLD. We enrolled 197 liver(More)
Sorafenib, a multi-kinase inhibitor, inhibits tumor angiogenesis and is the first-line systemic therapy for patients with advanced hepatocellular carcinoma (HCC). However, due to its limited effects and frequent occurrence of side effects, biomarkers are needed to predict the effects of sorafenib. We considered the possibility of using TIE-2-expressing(More)
Although several vitamin D-related gene polymorphisms were reported to affect the outcome of pegylated interferon/ribavirin (PR) therapy in chronic hepatitis C patients, there are no reports on the impact of the vitamin D-related gene polymorphisms in PR therapy combined with protease inhibitor (PI). Vitamin D-related gene polymorphisms were determined in(More)
AIM From a pharmacokinetic viewpoint, the use of ombitasvir/paritaprevir/ritonavir, one of the standards of care for genotype 1b chronic hepatitis C in Japan, could be possible in patients with impaired renal function. The aim of this study was to assess the efficacy and safety of this combination that have not yet been addressed in patients undergoing(More)
BACKGROUND Serum 25-hydroxyvitamin D3 levels are generally lower in chronic hepatitis C patients than in healthy individuals. The purpose of this study is to clarify the factors which affect serum 25-hydroxyvitamin D3 levels using data obtained from Japanese chronic hepatitis C patients. METHODS The subjects were 619 chronic hepatitis C patients. Serum(More)
BACKGROUND The aim of this study was to clarify the effectiveness and safety of sofosbuvir/ribavirin therapy for elderly patients with genotype 2-infected chronic hepatitis C (CHC) in Japan. METHODS A multicenter, retrospective study evaluated the effectiveness and safety of sofosbuvir/ribavirin based on real-world clinical data. RESULTS The subjects(More)
AIM Although interferon-free therapy with direct-acting antivirals has developed as a standard of care for chronic hepatitis C, the existence of resistance-associated variants (RAVs) has a negative impact on treatment results. Recently, several studies indicated a relationship between chronic hepatitis C and serum vitamin D levels. However, the relationship(More)
Sorafenib is a standard of care for advanced hepatocellular carcinoma (HCC). An in vitro study showed the synergistic effects of sorafenib and interferon for HCC. To clarify the efficacy, combination therapy with sorafenib and interferon was performed for patients with advanced HCC. Pegylated interferon α-2a was administered every 2 weeks for the initial 4(More)
OBJECTIVES This study investigated the relationship between hepatitis C virus (HCV) dynamics and sustained virological response (SVR), as well as the efficacy of an extended treatment with telaprevir-based triple therapy among patients with chronic hepatitis C genotype 1b. METHODS Among 220 patients receiving triple therapy for 24 weeks, the SVR rate was(More)
