Integrative transcriptomic and genomic analyses unveil the IFI16 variants and expression as MASLD progression markers.

Background And Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) encompasses a broad and continuous spectrum of liver diseases ranging from fatty liver to steatohepatitis. The intricate interactions of genetic, epigenetic, and environmental factors in the development and progression of MASLD remain elusive. Here, we aimed to achieve an integrative understanding of the genomic and transcriptomic alterations throughout the progression of MASLD.

Identification of signature gene set as highly accurate determination of metabolic dysfunction-associated steatotic liver disease progression.

Background/aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by fat accumulation in the liver. MASLD encompasses both steatosis and MASH. Since MASH can lead to cirrhosis and liver cancer, steatosis and MASH must be distinguished during patient treatment.

A case report of advanced hepatocellular carcinoma treated with hepatic arterial infusion chemotherapy and sorafenib combination therapy followed by metastasectomy of lung and muscle metastases.

Currently, various tyrosine kinase inhibitors and immune checkpoint inhibitors have been suggested in the treatment guidelines for advanced hepatocellular carcinoma (HCC). However, sorafenib was the only systemic drug approved 10 years ago. In 2010, a woman diagnosed with HCC rupture and multiple lung metastases visited our hospital.

Sorafenib with or without concurrent transarterial chemoembolization in patients with advanced hepatocellular carcinoma: The phase III STAH trial.

Background & Aims: Sorafenib is first-line standard of care for patients with advanced hepatocellular carcinoma (HCC), yet it confers limited survival benefit. Therefore, we aimed to compare clinical outcomes of sorafenib combined with concurrent conventional transarterial chemoembolization (cTACE) vs. sorafenib alone in patients with advanced HCC.

Mushroom Poisoning by .

There are currently over 5,000-known species of mushrooms worldwide. Only 20-25% of mushrooms have been named, and 3% of these are poisonous. More than 95% of mushroom poisoning cases occur due to difficulties associated with the identification of mushroom species.

A phase IIIb study of ledipasvir/sofosbuvir fixed-dose combination tablet in treatment-naïve and treatment-experienced Korean patients chronically infected with genotype 1 hepatitis C virus.

Background: The standard-of-care regimen for chronic hepatitis C virus (HCV) infection in Korea, pegylated-interferon-alpha plus ribavirin, is poorly tolerated. Ledipasvir/sofosbuvir is a two-drug, fixed-dose combination tablet approved in the USA, European Union, and Japan for chronic genotype 1 HCV infection.

Methods: This single-arm, phase IIIb study (NCT02021656) investigated the efficacy and safety of ledipasvir/sofosbuvir fixed-dose combination tablet for 12 weeks in treatment-naïve and treatment-experienced Korean patients chronically infected with genotype 1 HCV with or without compensated cirrhosis.

Real-Life Experience of Sorafenib Treatment for Hepatocellular Carcinoma in Korea: From GIDEON Data.

Purpose: The purpose of this study is to report real life experiences of sorafenib therapy for hepatocellular carcinoma (HCC) in Korea, using a subset of data from GIDEON (Global Investigation of Therapeutic Decisions in HCC and of Its Treatment with Sorafenib; a large, prospective, observational study).

Materials And Methods: Between January 2009 and April 2012, a total of 497 patients were enrolled from 11 sites in Korea. Of these, 482 patients were evaluable for safety analyses.

A Case of Sorafenib-induced DRESS Syndrome in Hepatocelluar Carcinoma.

Sorafenib is currently the only targeted therapy available for advanced stage hepatocellular carcinoma (HCC). Cutaneous adverse events associated with sorafenib treatment include hand-foot skin reaction, but there has been no report of drug reaction (or rash) with eosinophilia and systemic symptoms (DRESS) syndrome. Here, we report a case of 72-year-old man with HCC and alcoholic liver cirrhosis who developed skin eruptions, fever, eosinophilia, and deteriorated hepatic and renal function under sorafenib treatment.

Intraoperative radiofrequency ablation for hepatocellular carcinoma in 112 patients with cirrhosis: a surgeon's view.

Purpose: This retrospective study was an investigation of overall survival (OS), disease-free survival (DFS) and prognostic factors affecting OS and DFS in cirrhotic patients who received intraoperative radiofrequency ablation (IORFA).

Methods: Between April 2009 and November 2013, 112 patients (94 men, 84%; 18 women, 16%) underwent IORFA for 185 cases of hepatocellular carcinomas (HCC). Repeat IORFA was done in 9 patients during the same period (total of 121 treatments).

Targeted Regression of Hepatocellular Carcinoma by Cancer-Specific RNA Replacement through MicroRNA Regulation.

Hepatocellular carcinoma (HCC) has a high fatality rate and limited therapeutic options with side effects and low efficacy. Here, we proposed a new anti-HCC approach based on cancer-specific post-transcriptional targeting. To this end, trans-splicing ribozymes from Tetrahymena group I intron were developed, which can specifically induce therapeutic gene activity through HCC-specific replacement of telomerase reverse transcriptase (TERT) RNA.

Nonconvulsive status epilepticus disguising as hepatic encephalopathy.

Nonconvulsive status epilepticus has become an important issue in modern neurology and epileptology. This is based on difficulty in definitively elucidating the condition and its various clinical phenomena and on our inadequate insight into the intrinsic pathophysiological processes. Despite nonconvulsive status epilepticus being a situation that requires immediate treatment, this disorder may not be appreciated as the cause of mental status impairment.

Tumor-to-muscle ratio of 8F-FDG PET for predicting histologic features and recurrence of HCC.

Background/aims: Hepatocellular carcinoma (HCC) recurrence is observed in up to 70-80% of patients despite a curative treatment. Microvascular invasion (MVI) and poor differentiation are strong risk factors for recurrence, but these cannot be known preoperatively. The aim of this study was to investigate the correlation of 18F-FDG PET with MVI and differentiation, and predictive role of tumor-to-background ratio of PET for recurrence in HCC.

Retreatment with peginterferon and ribavirin in chronic hepatitis C.

The development of boceprevir and telaprevir was a major step forward in the treatment of chronic hepatitis C. In addition, the treatment of these infections has been recently revolutionized by the approval of sofosbuvir and simeprevir. However, there are several challenges associated with the application of novel drugs, such as new and more frequent adverse events, new drug interactions, and excessively high treatment costs.

Rapidly aggravated skeletal muscle metastases from an intrahepatic cholangiocarcinoma.

We present a rare case of intrahepatic cholangiocarcinoma (ICC) with multiple skeletal muscle metastases. The patient was a 55-year-old Asian woman presenting with abdominal pain; abdominal and pelvic computed tomography and magnetic resonance cholangiopancreatography revealed an unresectable ICC with hepatic metastasis and metastastatic lymphadenopathy in the porto-caval area. After 3 mo of treatment with palliative radiotherapy and chemotherapy, magnetic resonance imaging of the thoracolumbar spine detected right psoas muscle and paraspinous muscle metastases.

A case of focal nodular hyperplasia with growth progression during pregnancy.

Focal nodular hyperplasia (FNH) is the second most common benign solid tumor of the liver and is usually found in young females. In FNH, spontaneous bleeding or rupture rarely occurs and malignant transformation is unlikely. The etiology of FNH is unclear, but because of female predominance and young age at onset, it seems that female hormone has an important role for the development of FNH.

Serological and molecular characteristics of the first Korean case of Echinococcus multilocularis.

In December 2011, we reported an autochthonous case of Echinococcus multilocularis infection in a 42-year-old woman in Korea. The diagnosis was based on histopathological findings of the surgically resected liver cyst. In the present study, we evaluated the serological and molecular characteristics of this Korean E.

Simultaneous intrahepatic and subgaleal hemorrhage in antiphospholipid syndrome following anticoagulation therapy.

Warfarin is a widely used anticoagulant. Interindividual differences in drug response, a narrow therapeutic range and the risk of bleeding render warfarin difficult to use clinically. An 18-year-old woman with antiphospholipid syndrome received long-term warfarin therapy for a recurrent deep vein thrombosis.

Efficacy and safety of entecavir plus carnitine complex (GODEX®) compared to entecavir monotherapy in patient with ALT elevated chronic hepatitis B: randomized, multicenter open-label trials. The GOAL study.

Background/aims: Carnitine and vitamin complex (Godex®) is widely used in patients with chronic liver disease who show elevated liver enzyme in South Korea. The purpose of this study is to identify the efficacy and safety of carnitine from entecavir combination therapy in Alanine aminotransferase (ALT) elevated Chronic Hepatitis B (CHB) patients.

Methods: 130 treatment-naïve patients with CHB were enrolled from 13 sites.

Clinical features and outcomes of gastric variceal bleeding: retrospective Korean multicenter data.

Background/aims: While gastric variceal bleeding (GVB) is not as prevalent as esophageal variceal bleeding, it is reportedly more serious, with high failure rates of the initial hemostasis (>30%), and has a worse prognosis than esophageal variceal bleeding. However, there is limited information regarding hemostasis and the prognosis for GVB. The aim of this study was to determine retrospectively the clinical outcomes of GVB in a multicenter study in Korea.

Gastric ischemia after epinephrine injection in a patient with liver cirrhosis.

Endoscopic epinephrine injection is relatively easy, quick and inexpensive. Furthermore, it has a low rate of complications, and it is widely used for the management of nonvariceal upper gastrointestinal bleeding. There have been several case reports of gastric ischemia after endoscopic injection therapy.

Prognostic factors for gallbladder cancer in the laparoscopy era.

Purpose: Hepatobiliary surgery has changed dramatically in recent decades with the advent of laparoscopic techniques. The aim of this retrospective study was to compare survival rates according to stages, adjusting for important prognostic factors.

Methods: A retrospective study of a 17-year period from January 1994 to April 2011 was carried out.

Sodium iodide symporter and phosphatase and tensin homolog deleted on chromosome ten expression in cholangiocarcinoma analysis with clinicopathological parameters.

Background/aims: This study was performed to investigate the correlation of sodium iodide symporter (NIS) expression with the functionality and loss of phosphatase and tensin homolog deleted on chromosome ten (PTEN) expression in human cholangiocarcinoma (CCA).

Methods: Immunohistochemistry for the expression of NIS and PTEN was performed in 60 biopsy specimens of CCA. The clinicopathological parameters were retrospectively identified from medical records.

Aim: To investigate the efficacy of hepatic arterial infusion chemotherapy (HAIC) using floxuridine (FUDR) in patients with advanced hepatocellular carcinoma (HCC) confined to the liver.

Methods: Thirty-four patients who had advanced HCC with unresectability or unsuccessful previous therapy in the absence of extrahepatic metastasis were treated with intra-arterial FUDR chemotherapy at our hospital between March 2005 and May 2008. Among the 34 patients, 9 patients were classified as Child class C, and 18 patients had portal vein tumor thrombus (PVTT).

Recurrent hepatic alveolar echinococcosis: report of the first case in Korea with unproven infection route.

Human alveolar echinococcosis (AE), a hepatic disorder that resembles liver cancer, is a highly aggressive and lethal zoonotic infection caused by the larval stage of the fox tapeworm, Echinococcus multilocularis. E. multilocularis is widely distributed in the northern hemisphere; the disease-endemic area stretches from north America through Europe to central and east Asia, including northern parts of Japan, but it has not been reported in Korea.

A case of hepatic angiomyolipoma which was misdiagnosed as hepatocellular carcinoma in a hepatitis B carrier.

We report a rare case of resected hepatic AML, which was misdiagnosed as hepatocellular carcinoma in a chronic hepatitis B carrier. A 45-year-old woman who was a carrier of hepatitis B virus infection presented with a hepatic tumor. Her serum alpha-fetoprotein level was normal.
