2.Treatment of Hepatitis C in Special Conditions: Liver Cirrhosis.
Korean Journal of Medicine 2015;88(6):643-646
Acquiring a sustained virological response (SVR) in patients with cirrhosis or advanced hepatic fibrosis reduces liver disease-related mortality and the incidence of hepatocellular carcinoma. However, the SVR rate of the current standard of care, which is combination therapy with peg-interferon-alpha and ribavirin, is significantly lower, and treatment-related complications occur more frequently in patients with cirrhosis. Thus, antiviral treatment should be individualized in this population. This review highlights the issues associated with anti-hepatitis C virus treatment in patients with compensated and decompensated cirrhosis.

3.Renewed 2015 Clinical Practice Guidelines for Management of Hepatitis C by Korean Association for the Study of the Liver; What Has Been Changed? - Treatment of Patients with Decompensated Cirrhosis.
The Korean Journal of Gastroenterology 2016;67(3):137-141
HCV-related decompensated liver cirrhosis is a life-threatening illness with an average 5-year survival rate of 50%. Because these patients have higher risk of morbidity and mortality including development of hepatocellular carcinoma, the benefits of eradicating the virus may be greater than in those with less-advanced disease. Recently, direct-acting antiviral agents (DAAs) are replacing interferon-based regimens that have serious adverse events and low tolerability in the treatment of HCV infection. Many clinical trials using combination of several DAAs with or without ribavirin are now actively on-going in HCV-related decompensated cirrhosis, and encouraging data are beginning to appear. In this review, recent advances in the treatment of HCV-related decompensated cirrhosis are introduced with special focus on new DAAs.

4.Chronic Hepatitis B in Pregnancy.
Korean Journal of Medicine 2012;83(1):50-55
Hepatitis B virus (HBV) infection during pregnancy brings up unique management challenges. Varying aspects of care must be considered, including the effects of pregnancy on the course of HBV infection, effects of HBV infection on maternal and fetal health, treatment of HBV during and after pregnancy, and prevention of perinatal infection. For those with chronic HBV infection, the course of disease is usually unchanged during pregnancy. However, flares have been reported shortly after delivery. Women with high HBV DNA titer have an increased likelihood of perinatal transmission and may contribute to the failure of current passive-active immunoprophylaxis at birth. The aim of the present review is to provide a tool that may help physicians to manage correctly HBV infection in pregnancy.

5.Diagnosis of Non-alcoholic Fatty Liver Disease.
Journal of Korean Diabetes 2014;15(2):82-92
Although the classical gold standard for diagnosing and staging non-alcoholic fatty liver disease (NAFLD) and assessing fibrosis is liver biopsy, the procedure has several drawbacks, such as sample error, subjectivity in interpretation, high cost, and a small but real risk of complications.In an attempt to replace liver biopsy and to subcategorize patients with NAFLD into different prognoses, many non-invasive methods using various biomarkers, scoring systems, and imaging methods, such as elastography, have been attempted in the last decade. This article summarizes non-invasive diagnostic tests for the diagnosis of NAFLD/Nonalcoholic steatohepatitis, as well as the limitations and merits of liver biopsy.

Intestinal bypass surgery, particularly jejuno-ileal bypass surgery, performed for the purpose of weight reduction may cause an unexpected exacerbation of nonalcoholic steatohepatitis (NASH). Here, we report a case of NASH caused by small intestinal bacterial overgrowth, which developed after jejuno-colic bypass surgery and resolved dramatically after surgical correction.

The therapeutic effectiveness and safety of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) have been clinically established, and the procedure is now generally accepted as a curative treatment for very early or early stage HCC. Recently, we observed an aggressive recurrence after RFA for HCC in 50 year-old female. RFA was performed for a 2.7 cm sized HCC, which was completely ablated. However, 7 months later, aggressive intrahepatic recurrence was observed. Herein, we report a case with a discussion.

PURPOSE: To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) followed by radiotherapy (RT) in treatment-naive patients with locally advanced hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Eligibility criteria were as follows: newly diagnosed with HCC, the Barcelona Clinic Liver Cancer stage C, Child-Pugh class A or B, and no prior treatment for HCC. Patients with extrahepatic spread were excluded. A total of 59 patients were retrospectively enrolled. All patients were treated with TACE followed by RT. The time interval between TACE and RT was 2 weeks as per protocol. A median RT dose was 47.25 Gy10 as the biologically effective dose using the alpha/beta = 10 (range, 39 to 65.25 Gy10). RESULTS: At 1 month, complete response was obtained in 3 patients (5%), partial response in 27 patients (46%), stable disease in 13 patients (22%), and progressive disease in 16 patients (27%). The actuarial one- and two-year OS rates were 60.1% and 47.2%, respectively. The median OS was 17 months (95% confidence interval, 5.6 to 28.4 months). The median time to progression was 4 months (range, 1 to 35 months). Grade 3 or greater liver enzyme elevation occurred in only two patients (3%) after RT. Grade 3 gastroduodenal toxicity developed in two patients (3%). CONCLUSION: The combination treatment of TACE followed by RT with two-week interval was safe and it showed favorable outcomes in treatment-naive patients with locally advanced HCC. A prospective randomized trial is needed to validate these results.

BACKGROUND/AIMS: Visceral larva migrans, caused by Toxocara canis and Toxocara cati, has emerged as a significant cause of eosinophilic liver abscess (ELA). Differentiation of ELA associated with toxocariasis (ELA-T) from metastasis or primary liver malignancy is sometimes difficult. However, the role of albendazole treatment remains uncertain in this condition. The aim of this study was to evaluate whether albendazole can enhance the radiologic resolution of ELA-T. METHODS: We retrospectively reviewed the medical records of the patients diagnosed with ELA-T at our institution between January 2008 and December 2011. ELA-T was diagnosed based on the imaging findings on computed tomography or magnetic resonance imaging and the presence of positive serum IgG antibody for Toxocara canis. Among a total of 163 patients, 32 patients received albendazole (albendazole group) and 131 did not (control group). Baseline characteristics and fate of liver nodules were compared between the two groups. RESULTS: Baseline characteristics (age, sex, number and maximal size of lesions, eosinophil count) were similar between the two groups. Median duration for achieving radiologic resolution in the albendazole group was significantly shorter than in the control group (207 days [range 186-228] vs. 302 days [range 224-380], p=0.023). In Cox regression analysis of the cumulative rates of radiologic resolution, the hazard ratio for albendazole treatment was 1.99 (95% confidence interval, 1.22-3.23). CONCLUSIONS: Radiologic resolution of ELA-T can be accelerated with albendazole treatment. Hence, inconvenience associated with long-term follow-up and unnecessary worries among patients can be eliminated with albendazole treatment.
