ABSTRACT
Chronic hepatitis C (CHC) treatment has dramatically improved since direct-acting antiviral (DAA) therapy was introduced. However, the use of DAA therapy in CHC patients with hepatocellular carcinoma (HCC) remains controversial. We investigated the DAA treatment response in CHC patients with HCC. Methods: We retrospectively analyzed CHC patients treated with DAA from 2016 to 2018. Patients were divided into two groups based on their HCC-history before DAA therapy. Baseline characteristics, sustained virologic response at 12 weeks (SVR 12), and HCC recurrence after DAA therapy were evaluated. We also used propensity score matching (PSM) in a 2:1 ratio to reduce confounding variables. Results: A total of 192 patients were enrolled; 78.1% were treatment-naïve, and 34.9% had liver cirrhosis (LC). Among these patients, 168 did not have HCC, and 24 had HCC. The HCC group was older (57.0 years vs. 72.0 years, p < 0.001), had a higher incidence of LC (26.2% vs. 95.8%, p < 0.001), fibrosis-4 index (2.6 vs. 9.2, p < 0.001), liver stiffness measurement (7.0 kPa vs. 17.4 kPa, p = 0.012), and α-fetoprotein (4.4 ng/mL vs. 8.2 ng/mL, p ≤ 0.001). The SVR 12 rate was 97.0% in the non- HCC group and 91.7% in the HCC group (p = 0.213). HCC recurrence was observed in 14 patients (58.3%) in the HCC group. Conclusions: DAA treatment efficacy in CHC patients with or those without HCC were not significantly different, and HCC recurrence was relatively common.
ABSTRACT
Background/Aims@#The HBsAg levels have been used to monitor the chronic hepatitis B (CHB) treatment response to antiviral therapy.On the other hand, it is unclear if the HBsAg quantification levels at each treatment point differ according to the HBeAg status and drug in CHB patients. This study compared the changes in HBsAg in CHB patients according to the HBeAg status and treatment drugs. @*Methods@#CHB patients with at least 1 year of follow-up treatment with one drug, either entecavir (ETV) or tenofovir (TDF), were enrolled in this study. The mean HBsAg levels were measured annually for up to 6 years. A linear mixed model was used to compare the HBsAg quantification levels during the follow-up period. An independent samples t-test was used to analyze the differences in the HBsAg quantification levels at each treatment time point. @*Results@#Ninety-seven patients were enrolled in this study; 59 among them were HBeAg-positive. Two patients in the TDF group achieved HBsAg seroconversion. The HBsAg level decreased during the follow-up in the ETV and TDF groups. The HBsAg level was lower in the TDF group than the ETV group during the follow-up. On the other hand, subgroup analysis showed that this trend was the same only in the HBeAg-negative patients, not in the HBeAg-positive patients. In the HBeAg-negative patients, HBsAg level in the TDF group was significantly lower than that in the ETV group at 36, 48, and 72 months. The change in HBsAg level from the baseline increased at a decreasing rate during the follow-up in both groups. Furthermore, the change in the HBsAg level in the TDF group was significantly larger than that of the ETV group at 36 months in the HBeAg-negative patients. @*Conclusions@#Although TDF might be more efficient than ETV in reducing the HBsAg level in HBeAg-negative patients in a few years, HBsAg seroconversion occurred very rarely. A further large-scale, long-term study will be needed to confirm the antiviral effects on the HBsAg level.
ABSTRACT
Background/Aims@#Because hepatitis B virus (HBV) replication has been known to play animportant role in cancer recurrence after curative treatment of HBV-related hepatocellularcarcinoma (HCC), we examined whether treatment based on nucleos(t)ide analogues (NAs)might decrease the recurrence rate and improve patient survival. @*Methods@#The retrospective cohort study enrolled 73 patients with chronic hepatitis B whowere treated with transarterial chemoembolization (TACE) and radiofrequency ablation (RFA)with curative intent for HCC. Among those, 30 and 43 patients were treated with tenofovirdisoproxil fumarate (TDF) and entecavir (ETV), respectively. @*Results@#Of the 73 patients, 51 experienced HCC recurrence, and 14 patients were deadduring a follow-up of 73±34 months. Multivariate analyses showed that tumor size (hazardratio [HR], 1.590; 95% confidence-interval [CI], 1.106-2.285; P=0.012) and Child-Pugh class B(vs. class Aon cirrhosis; HR, 5.794; 95% CI, 2.311-14.523; P=0.001) was significantly associatedwith HCC recurrence, and Child-Pugh class B (HR, 7.357; 95% CI, 2.100-25.777; P=0.002) was anindependent unfavorable prognostic factor for survival. During NAs therapy, TDF was superiorto ETV for complete viral response at 1 year after the date of combination of TACE and RFA(P=0.016). However, the risks of HCC recurrence and survival were not significantly differentbetween those treated with TDF versus ETV. @*Conclusions@#TDF was superior to ETV for achieving complete viral response. However, therecurrence and mortality after TACE and RFA for HBV-related HCC were not significantlydifferent between patients treated with TDF versus ETV.

ABSTRACT
Background/Aims@#Chronic hepatitis C virus (HCV) infections put patients at risk of serious liver disease and adversely affects patient quality of life (QoL). MOSAIC (International Multicenter Prospective Observational Study to Evaluate the Epidemiology, Humanistic and Economic Outcomes of Treatment for Chronic Hepatitis C Virus) was a prospective, non-interventional, international, multicenter study that aimed to describe the epidemiology of the infection, the impact of the infection on health-related QoL (HRQoL) and daily activities, and healthcare resource use related to HCV and treatment. Here, we present the results on HRQoL and daily activity impairment in consecutively enrolled South Korean patients treated with interferon (IFN)-containing regimens prospectively followed for up to 48 weeks. @*Methods@#General HRQoL, HCV-specific HRQoL, perceived health state, and work/general activity impairments were measured using the EuroQoL 5-dimension 5-level (EQ-5D-5L), HCV patient-reported outcomes (HCV-PRO), EQ-5D Visual Analog Scale, and Work Productivity and Activity Impairment questionnaires, respectively. @*Results@#Thirty-three of the 100 enrolled patients initiated IFN-based treatment, with an intended duration of 24 weeks for 20 patients and 48 weeks for 12 patients; this information was missing for one patient. Fourteen patients (42.4%) prematurely withdrew. After treatment initiation, IFN-treated patients showed a trend towards deterioration of both general (baseline: 0.87±0.103, week 4: 0.77±0.153) and HCV-specific (baseline: 76.2±19.5, week 4: 68.2±22.3) HRQoL. The scores recovered somewhat towards the end of treatment (EOT) (0.84±0.146 for EQ-5D-5L and 70.8±21.9 for HCV-PRO). The perceived health state and work/general activity impairment displayed similar temporal patterns. @*Conclusions@#Initiating IFN-based treatment prompted some deterioration in general and HCV-related HRQoL, accompanied by impaired daily activities and most work productivity measures; however, the HRQoL and productivity scores improved towards the EOT. HRQoL impairment upon treatment initiation likely contributed to treatment discontinuation.
ABSTRACT
Background/Aims@#Intrahepatic cholangiocarcinoma (ICC) is the second-most common primary liver malignancy, arising from the peripheral intrahepatic bile duct epithelium. Hepatitis B virus (HBV) or hepatitis C virus (HCV) may be involved in the development of ICC. We explored the prognostic value of hepatitis virus infection, as well as other prognostic factors affecting survival in patients with ICC. @*Methods@#A retrospective chart review was performed for patients diagnosed with ICC between August 2005 and December 2018 at Konkuk University Medical Center. We identified a total of 131 patients with ICC. Overall survival rates of patients with and without hepatitis were determined. Univariate and multivariate analyses were used to estimate factors influencing survival outcomes. @*Results@#A total of 17.6% (23/131) of patients were positive for HBV or HCV. Hepatitis B positive ICC patients were significantly younger with higher albumin and higher α-fetoprotein than those without hepatitis viral infections. The median survival of hepatitis-positive and hepatitis-negative groups was 280 and 213 days, respectively. Survival rates were not significantly different between the two groups (p = 0.279). Multivariate analyses indicated that lower serum carbohydrate antigen 19-9 (CA 19-9) (p < 0.001), lower T stage (p = 0.042), the absence of lymph-node metastasis (p = 0.043), and receiving curative surgery (p = 0.033) were independent predictors of better outcomes. @*Conclusions@#While hepatitis influenced a number of clinical features in ICC patients, it did not affect survival rate. Prognostic factors influencing survival outcomes with ICC were CA 19-9 level, T stage, the presence of lymph node metastasis, and curative surgery.
ABSTRACT
BACKGROUND/AIMS: A switch to systemic therapy, such as sorafenib, should be considered for hepatocellular carcinoma (HCC) patients refractory to transarterial chemoembolization (TACE). On the other hand, treatment changes are difficult if the liver function worsens to Child-Pugh B or C. Therefore, predicting the risk factors for non-responsiveness to TACE and deteriorating liver function may be helpful.METHODS: Newly diagnosed Child-Pugh A HCC patients who underwent TACE from January 2012 to June 2018 were included. After 1 year, this study evaluated whether there was a treatment response to TACE and whether the Child-Pugh class had worsened.RESULTS: Among 121 patients, 65 were refractory and 56 responded to TACE. In multivariable logistic regression analysis, the tumor size, tumor number, and albumin at the time of the diagnosis of HCC were significant prognostic factors for the treatment response to TACE. Among 65 patients who presented TACE-refractoriness, 27 showed liver function deterioration from Child-Pugh class A to class B or C after TACE. In multivariable logistic regression analysis, bilirubin at the diagnosis of HCC was a significant prognostic factor for liver function deterioration. A predictive algorithm based on the regression equations revealed a sensitivity, specificity, positive predictive value, and negative predictive value of 74.1%, 74.5%, 45.5%, and 90.9%, respectively, for TACE-refractoriness and liver function deterioration.CONCLUSIONS: The prognostic model incorporating the tumor size, tumor number, albumin, and bilirubin at the diagnosis of HCC may help identify patients who show a poor response to TACE and aggravation of liver function after TACE, who may benefit from early switching into systemic therapy before liver function aggravation.
ABSTRACT
BACKGROUND/AIMS: Surgical resection or ablation is recommended for the treatment of early hepatocellular carcinoma (HCC), whereas transarterial chemoembolization (TACE) is frequently used in early HCC ineligible for curative resection. We evaluated the clinical effects and safety of radiofrequency ablation (RFA) shortly after TACE in patients with Barcelona clinic liver cancer (BCLC) stage A HCC. METHODS: Sixty-seven BCLC stage A HCC patients who failed to achieve complete response to TACE as either a first line treatment and who subsequently received RFA at the Konkuk University Medical Center from January 2005 to December 2017 were included. Evaluation indices included treatment response, overall survival rate, recurrence-free survival, prognostic factors, and procedure-related complications. RESULTS: Median follow-up was 46.9 months. Fifty-four (80.6%) patients were of Child-Pugh class A, and 13 (19.4%) were of class B. Modified UICC stages were I in 10 (14.9%), II in 46 (68.7%), and III in 11 (16.4%) patients. In the 67 study subjects, cumulative recurrence-free survival rates were 86.8%, 55.9% and 29.7% at 1, 3, and 5 years, respectively, and overall survival rates were 100%, 93.4%, and 83.5% at 1, 3, and 5 years, respectively. Tumor size significantly predicted recurrence. No treatment-related death occurred. CONCLUSIONS: Combination of RFA was an efficient and safe treatment for BCLC stage A HCC patients that failed to achieve complete response to initial TACE. We suggest TACE plus RFA be considered as a curative option for early HCC patients ineligible for curative resection of RFA.

The advent of novel, direct-acting antiviral (DAA) regimens for hepatitis C virus (HCV) infection has revolutionized its treatment by producing a sustained virologic response of more than 95% with few side effects and no comorbidities in the general population. Until recently, ideal DAA regimens have not been available to patients with severe renal impairment and end-stage renal disease because there are limited data on the pharmacokinetics, safety, and efficacy of treatment in this unique population. In a hemodialysis context, identifying patients in need of treatment and preventing HCV transmission may also be a matter of concern. Recently published studies suggest that a combination of paritaprevir/ritonavir/ombitasvir and dasabuvir, elbasvir/grazoprevir, or glecaprevir/pibrentasvir successfully treats HCV infection in chronic kidney disease stage 4 or 5 patients with or without hemodialysis.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a serious infectious complication in patients with liver cirrhosis. However, information about prognosis of SBP in hepatocellular carcinoma (HCC) patients is limited. We investigated the clinical course of SBP in HCC patients. METHODS: This study enrolled patients diagnosed with SBP between 2005 and 2017. Medical records of patients were reviewed and clinical course was compared between the non-HCC and HCC groups. RESULTS: In total, 123 SBP cases including 49 HCC cases were enrolled. Men were predominant (48/74, 64.9% vs. 34/49, 69.4%; P = 0.697); median age was 58 years in both non-HCC and HCC groups (P = 0.887). The most common etiology was alcohol (32/74, 43.2%) in non-HCC group and hepatitis B (30/49, 61.2%) in HCC group (P = 0.009). Antibiotic resistance rate was higher in non-HCC than in HCC group (29.7% vs. 12.2%; P = 0.028); in-hospital mortality did not differ between the groups (25/74, 33.8% vs. 13/49, 26.5%; P = 0.431). Development rate of hepatorenal syndrome did not differ between non-HCC and HCC group (14/74, 18.9% vs. 10/49, 20.4%; P = 1.000), but hepatic encephalopathy was less common in HCC group (26/74, 35.2% vs. 9/49, 18.3%; P = 0.008). The most important predictor of in-hospital mortality in patients with HCC was white blood cell count above 11,570 cells/mm3 (odds ratio, 6.629; 95% confidence interval, 1.652–26.590; P = 0.008). CONCLUSION: Prognosis of SBP in HCC patients is relatively less severe. This result may be related with reduced antibiotics resistance and lower development rates of other complications, such as hepatic encephalopathy. Degree of systemic inflammation may be the most important factor for in-hospital mortality.

BACKGROUND/AIMS: Direct-acting antiviral (DAA) therapy has been shown to achieve a high rate of sustained virologic response (SVR) and favorable outcomes in chronic hepatitis C (CHC) patients. We investigated the virologic response and its clinical impact in CHC patients. METHODS: CHC patients with compensated liver function treated with DAAs between 2016 and 2017 were included for retrospective analysis. We analyzed baseline characteristics and virologic and biochemical responses at on-treatment 4 weeks, end of treatment, and post-treatment 12 weeks. Fibrosis was measured as liver stiffness measurement by transient elastography (FibroScan). Adverse events were monitored during the treatment period. RESULTS: A total of 135 patients (61.5% with genotype [GT] 1b and 38.5% with GT 2a) were enrolled 47.4% were male, 79.3% were treatment naive, and 30.4% had cirrhosis. SVR 12 was observed in 97.6% (81/83) in the GT 1b and 98.1% (51/52) in the GT 2a; treatment with daclatasvir+asunaprevir was the most commonly used in GT 1b (55/83), and sofosbuvir+ribavirin was the most commonly used in GT 2a (49/52). The median change of liver stiffness measurement at two time points using the signed rank test was -3.2 kPa in patients who underwent transient elastography before treatment and at SVR 12 (n=25). The most common adverse events were anemia, dyspepsia, and insomnia. One GT 2a patient treated with sofosbuvir+ribavirin stopped the treatment at 8 weeks due to symptomatic bradyarrhythmia; however, he recovered spontaneously and achieved SVR 12. CONCLUSIONS: DAA treatment of chronic hepatitis C genotype 1b and 2a resulted in a high rate of sustained virologic response and improvement of liver fibrosis score.

BACKGROUND: Liver biopsies have been partially replaced by noninvasive methods for assessing liver fibrosis. We explored the usefulness of four novel biomarkers, enhanced liver fibrosis (ELF), glycosylation isomer of Mac-2 binding protein (M2BPGi), galectin-3, and soluble suppression of tumorigenicity 2 (sST2), in association with liver fibrosis. METHODS: ELF, M2BPGi, galectin-3, and sST2 were assayed in 173 patients with chronic liver diseases. The results were analyzed according to fibrosis grade (F0/1, F2, and F3/4) by transient elastography (TE). RESULTS: ELF, M2BPGi, galectin-3, and sST2 values differed significantly according to TE grade; ELF and M2BPGi values were higher in F2 and F3/4 than in F0/1 (P≤0.001, all), sST2 values were higher in F3/4 than in F0/1 and F2 (P < 0.05), and galectin-3 values were higher in F3/4 than in F0/1 (P=0.0036). ELF and M2BPGi showed good TE fibrosis detection performance (area under the curves [AUC], 0.841 and 0.833 for ≥F2; and 0.837 and 0.808 for ≥F3). The sensitivity and specificity for predicting TE grade F≥2 were 84.1% and 76.7% for ELF and 63.6% and 91.5% for M2BPGi. CONCLUSIONS: This is the first study to compare the liver fibrosis assessment of four novel biomarkers: ELF, M2BPGi, galectin-3, and sST2. The biomarkers varied significantly according to TE grade, and each biomarker showed a different trend. ELF and M2BPGi seem to have comparable good performance for detecting liver fibrosis.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) is one of critical complications in liver cirrhosis patients with ascites. We aimed to review clinical course of SBP patients in a 10-year period from single center. METHODS: This study enrolled SBP patients between 2005 and 2015. Their medical records were reviewed. The laboratory findings of serum and ascites were examined, and characteristics of isolated microorganisms in ascites were analyzed. RESULTS: Total 51 patients were enrolled. Male patients were predominant (64.7%), and mean age was 59.20 years. The most common etiology of cirrhosis was alcohol (41.2%), followed by hepatitis B (39.2%). Microorganism was isolated from the ascites in 31 patients (60.78%). The proportions of Gram negative and Gram positive were 80.64% and 19.36%. The proportions of Escherichia coli, Klebsiella, and Streptococcus species were 29.41%, 19.61% and 11.76%. Among Escherichia colis, 4 cases were ESBL positive (7.84%). The most commonly used first-line antibiotic was cefotaxime (80.40%). Prophylactic antibiotics treatment was performed only in 8 patients, and SBP was recurred in 7 patients (13.72%). When comparing the SBP recurrence group and the non-recurrence group, there were no significant differences in laboratory findings of serum and ascitic fluid. CONCLUSIONS: SBP is still a critical complication in cirrhosis patients with ascites, and the clinical features of SBP have not been altered much compared with those in 1990's. The effective treatment of SBP is still very important for a better prognosis of cirrhosis patients.

BACKGROUND/AIMS: Little is known about the effect of early flares on response during first-line tenofovir disoproxil fumarate (TDF) treatment for chronic hepatitis B (CHB). The aim of this study was to investigate the incidence and outcome of early alanine aminotransferase (ALT) flare in treatment-naive patients with CHB during long-term TDF monotherapy. METHODS: One hundred eighty-one treatment-naive CHB patients were treated with a 300-mg once-daily dose of TDF for more than 12 weeks. Virological markers of hepatitis B virus (HBV) and biochemical data were measured at baseline and every 4-12 weeks during the therapy. The proportion of patients with undetectable HBV DNA level (5 × upper limit of the normal range) occurred in seven patients (3%) without viral breakthrough within the first 8 weeks after the start of TDF monotherapy. Among them, six patients were HBeAg-positive and one patient was HBeAg-negative. All cases of early ALT flares resolved within 4 weeks and virologic response was observed in all patients without interruption or discontinuation of treatment. CONCLUSIONS: Continuous TDF monotherapy was effective and safe in treatment-naive patients with CHB who experienced early ALT flares followed by a decrease in HBV DNA level.

BACKGROUND/AIMS: Before tenofovir (TDF) become available in South Korea, combination therapy with entecavir (ETV) and adefovir (ADV) was the most potent regimen for chronic hepatitis B (CHB) patients who fail to respond to rescue therapy for drug resistance. We analyzed the efficacy of ETV-ADV combination therapy and investigated the clinical and clonal results of TDF-based rescue therapy in CHB patients refractory to this combination. METHODS: We retrospectively reviewed the medical records of CHB patients treated for up to 3 years with ETV-ADV combination therapy as a rescue therapy for drug resistance. In cases refractory to this combination, clinical and clonal analyses were performed for TDF-based rescue therapy. RESULTS: The analysis was performed on 48 patients. Twelve patients achieved a virological response (VR) within 3 years. A VR was subsequently achieved in nine of the ten patients without a VR who switched to TDF monotherapy. A VR was also achieved in six of the seven patients who switched to lamivudine-TDF combination therapy, and in two of the two patients who switched to ETV-TDF combination therapy. In an in vitro susceptibility test, viral replication was detected with TDF monotherapy but not with ETV-TDF combination therapy. CONCLUSIONS: The efficacy of ETV-ADV combination therapy was insufficient in CHB patients who were refractory to rescue therapy. A more potent regimen such as ETV-TDF combination therapy may be considered in such refractory cases.

Portal biliopathy is defined as abnormalities in the extra- and intrahepatic ducts and gallbladder of patients with portal hypertension. This condition is associated with extrahepatic venous obstruction and dilatation of the venous plexus of the common bile duct, resulting in mural irregularities and compression of the biliary tree. Most patients with portal biliopathy remain asymptomatic, but approximately 10% of them advance to symptomatic abdominal pain, jaundice, and fever. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are currently used as diagnostic tools because they are noninvasive and can be used to assess the regularity, length, and degree of bile duct narrowing. Management of portal biliopathy is aimed at biliary decompression and reducing the portal pressure. Portal biliopathy has rarely been reported in Korea. We present a symptomatic case of portal biliopathy that was complicated by cholangitis and successfully treated with biliary endoscopic procedures.

BACKGROUND/AIMS: Nucleos(t)ide analogues (NAs) help reduce the recurrence rate after the curative treatment of hepatitis B related hepatocellular carcinoma (HCC). Sorafenib has been shown to improve survival of advanced HCC patients. Whether antiviral therapy with NAs could help such patients is unknown. Our aim is to investigate the usefulness of antiviral therapy for advanced-stage HCC treated with sorafenib. METHODS: We performed a retrospective cohort study in advanced-stage HCC patients treated with sorafenib between June 2007 and December 2013. Patients in group A (the non-antiviral therapy group) were treated with sorafenib alone. Those in group B (the antiviral therapy group) were treated with sorafenib and NAs. Progression-free survival (PS) and overall survival (OS) were compared between these two groups. RESULTS: Finally, 23 patients in group A and 40 patients in group B were enrolled in the study. The mean number of days of treatment with sorafenib was 79 (34-231) days and 96 (33-449) days for group A and B, respectively (P=0.286). The mean PS of group A and B was 97 (14-449) days and 51 (0-461) days, respectively (P=0.068). The OS was 154 (44-741) days in group A and 138 (30-1,025) days in group B (P=0.665). PS and OS showed no significant difference between the two groups. CONCLUSIONS: This study shows that there was no significant survival gain of using antiviral therapy in patients with advanced-stage HCC treated with sorafenib. In consideration of cost-effectiveness, antiviral therapy may be not mandatory.

Immunoglobulin G4-related disease is a recently recognized entity characterized by a mass-forming or regional lesion that contains an extensive infiltration of IgG4-producing plasma cells with dense fibrosis. Immunoglobulin G4-related disease can affect any organ system, but solitary hepatic lesion of Immunoglobulin G4-related disease is very rare. This entity mimics primary malignant hepatic tumor, such as hepatocellular carcinoma or intrahepatic cholangiocarcinoma. We experienced a case of hepatic IgG4-related inflammatory pseudotumor in a 50-year-old woman, mimicking hepatocellular carcinoma.
