RESUMEN

Background and Objectives: Transarterial chemoembolization (TACE) is a widely accepted treatment for hepatocellular carcinoma (HCC). Regarding TACE, arterial injuries, such as hepatic artery spasm or dissection, can also occur, although pseudoaneurysms are rare. We report a case of pseudoaneurysm following TACE. Materials and Methods: A 78-year-old man had been undergoing TACE for HCC in segment 8 of the liver for the past 5 years, with the most recent TACE procedure performed approximately 1 month prior. He presented to the emergency department with melena that persisted for 5 days. Computed tomography revealed a pseudoaneurysm in the S8 hepatic artery with hemobilia. Results: the pseudoaneurysm was successfully treated by N-Butyl-cyanoacrylate glue embolization. Conclusions: In patients that have undergone TACE presenting with melena and hemobilia identified on CT, consideration of hepatic artery pseudoaneurysm is crucial. Such cases can be safely and effectively treated with endovascular managements.

RESUMEN

BACKGROUND & AIMS: Loss-of-function HSD17ß13 mutations protect against the development of chronic liver disease. HSD17ß13 inhibition represents a potential approach to treat liver diseases, such as non-alcoholic steatohepatitis (NASH). ARO-HSD is an RNA interference (RNAi) therapeutic designed to selectively reduce expression of HSD17ß13 mRNA in hepatocytes. In this study, we evaluated the effects of ARO-HSD in normal healthy volunteers (NHVs) and patients with confirmed or clinically suspected NASH. METHODS: The safety, tolerability, and pharmacodynamics of ARO-HSD were evaluated in 32 NHVs and 18 patients with confirmed/clinically suspected NASH. Double-blind NHV cohorts received single escalating doses of ARO-HSD (25, 50, 100, or 200 mg) or placebo subcutaneously on Day 1. Open-label patient cohorts received ARO-HSD (25, 100, or 200 mg) subcutaneously on Days 1 and 29. Liver biopsy was performed pre-dose and on Day 71 to evaluate expression levels of HSD17ß13 mRNA and protein. RESULTS: ARO-HSD treatment was well tolerated with no treatment-related serious adverse events or drug discontinuations. The most frequently reported treatment-emergent adverse events were mild injection site reactions, which were short in duration. Mean changes in hepatic HSD17ß13 mRNA from baseline to Day 71 were: -56.9% (25 mg), -85.5% (100 mg), and -93.4% (200 mg). The mean HSD17ß13 mRNA reduction was 78.6% (p <0.0001) across pooled cohorts. Hepatic HSD17ß13 protein levels were similarly reduced across doses. In patients, mean changes in alanine aminotransferase from baseline to Day 71 were -7.7% (25 mg), -39.3% (100 mg), and -42.3% (200 mg) (p <0.001 for pooled cohorts). CONCLUSIONS: ARO-HSD was well tolerated at doses ≤200 mg. This proof-of-concept study demonstrated that short-term treatment with ARO-HSD reduces hepatic HSD17ß13 mRNA and protein expression, which is accompanied by reductions in alanine aminotransferase. GOV NUMBER: NCT04202354. IMPACTS AND IMPLICATIONS: There is an unmet medical need for new therapies to treat alcohol-related and non-alcoholic liver disease. ARO-HSD is a small-interfering RNA designed to silence HSD17ß13 expression and hence to phenocopy the protective effect seen in individuals with HSD17ß13 loss-of-function. The reductions in HSD17ß13 expression and in transaminases seen with ARO-HSD administration represent an initial step towards clinical validation of HSD17ß13, a drug target with substantial genetic validation, as an important modulator of human liver disease.

RESUMEN

BACKGROUND: Life-threatening bleeding following endoscopic variceal ligation (EVL) in patients with cirrhosis rarely can occur. The present study aimed to evaluate the performance of computed tomography (CT) in predicting the risk of early bleeding following EVL in cirrhotic patients. METHODS: We retrospectively investigated 285 cirrhotic patients who had undergone EVL. EVL was performed for prophylaxis or acute variceal bleeding. The patients were classified into 2 groups: early bleeding (< 14 days after EVL) and non-early bleeding. We compared baseline characteristics including CT findings between the patient groups. RESULTS: Among the 285 patients who underwent EVL treatment, 19 patients (6.7%) experienced early bleeding. On average, these bleeding occurred 9.3 ± 3.5 days after the EVL, with a range of 3 to 13 days. Patients who experience early bleeding had a higher six-week bleeding-related mortality rate compared to those in the non-early bleeding group (31.6% vs. 10.2%; p = 0.014). There was a correlation between the grade of esophageal varix observed during endoscopy and the diameter of esophageal varix observed on CT (p < 0.001). The diameter of esophageal varix on CT was identified as the only significant predictive factor for early bleeding (p = 0.005). CONCLUSION: A larger esophageal varix diameter observed on CT is associated with an increased risk of early bleeding after EVL treatment. Early identification of this high-risk group can provide a change of treatment strategies to improve patient outcomes.

RESUMEN

BACKGROUND: This study aimed to investigate the prevalence rate of hepatitis C virus (HCV) infection and identify the demographic, and sociological characteristics and changes in awareness of HCV infection by participating the study for North Korean defectors residing in South Korea. METHODS: This study prospectively enrolled participants. Demographic, sociological and clinical data, and questionnaire surveys focused on awareness of HCV infection were collected. RESULTS: In total, 211 North Korean defectors participated in this study from September 2020 until June 2021. There were 174 women (82.5%), and the overall mean age was 48.9 years (range, 20 to 80 years). Of these participants, 112 (53.1%) had immigrated to South Korea since 2011. The overall prevalence of anti-HCV antibody among North Korean defectors was 1.9%. Thirty participants (14.2%) had hepatitis B surface antigens. A huge lack of awareness regarding HCV infection has been observed among North Korean defectors. CONCLUSION: This is the first prospective study to investigate the prevalence rate of HCV infection among North Korean defectors residing in South Korea. As North Korean defectors are a vulnerable group concerning HCV infection, they may benefit from HCV screening policies and educational interventions for HCV infection.

RESUMEN

BACKGROUND AND AIMS: ARC-520, the first an RNA interference (RNAi) therapeutic, was designed to reduce all RNA transcripts derived from covalently closed circular DNA, leading to a reduction in viral antigens and hepatitis B virus (HBV) DNA. APPROACH AND RESULTS: We aimed to evaluate the depth of hepatitis B surface antigen (HBsAg) decline in response to multiple doses of ARC-520 compared to placebo (PBO) in two randomized, multicenter studies in nucleoside/nucleotide analogue reverse-transcriptase inhibitor (NUC)-experienced patients with hepatitis B early antigen (HBeAg)-negative (E-neg) or HBeAg-positive (E-pos) disease. A total of 58 E-neg and 32 E-pos patients were enrolled and received four monthly doses of PBO (n = 20 E-neg, 11 E-pos), 1 mg/kg ARC-520 (n = 17 E-neg, 10 E-pos), or 2 mg/kg ARC-520 (n = 21 E-neg, 11 E-pos) concomitantly with NUC. HBsAg change from baseline to 30 days after the last ARC-520 dose were compared to PBO. Both E-neg and E-pos high-dose groups significantly reduced HBsAg compared to PBO, with mean reductions of 0.38 and 0.54 log IU/mL, respectively. HBsAg reductions persisted for approximately 85 days and >85 days after the last dose in E-neg and E-pos patients, respectively. The low-dose groups did not reach statistical significance in either study. E-pos patients showed a dose-dependent reduction in HBeAg from baseline. Mean maximum reduction was 0.23 and 0.69 log Paul Ehrlich IUs/mL in the low-dose and high dose ARC-520 groups respectively. ARC-520 was well tolerated, with only two serious adverse events of pyrexia possibly related to study drug observed. CONCLUSIONS: ARC-520 was active in both E-neg and E-pos, NUC-experienced HBV patients; but absolute HBsAg reductions were moderate, possibly due to expression of HBsAg from integrated HBV DNA, indicating the need for RNAi therapeutics that can target viral transcripts regardless of origin.

RESUMEN

PURPOSE OF REVIEW: Cirrhotic cardiomyopathy (CCM) is a well-recognized entity. When patients with CCM encounter challenges such as liver transplantation, overt cardiac dysfunction manifests, leading to morbidity and mortality. Although revised diagnostic criteria for CCM have recently been proposed, these still need to be validated. RECENT FINDINGS: Previous reviews have summarized the mechanisms of CCM, such as abnormalities of the ß-adrenergic pathway, cardiac plasma membrane biophysical and biochemical properties, and electrophysiological changes. Cardiomyocyte apoptosis, inflammation, and oxidative stress also play important roles. The present review details further mechanisms of CCM, which include myosin heavy chain isoform shifts and abnormalities in cellular calcium transients. Additionally, we review recent studies on therapeutic strategies. Recent work underscores the importance of CCM in the natural history of the immediate and medium-term postoperative period after liver transplantation. Appropriate management strategies for CCM remain the area of greatest unmet need, requiring much further research. SUMMARY: CCM is a clinically relevant syndrome affecting patients with cirrhosis, leading to increased morbidity and mortality. New diagnostic criteria have been recently proposed by an expert working group. The pathogenic mechanisms remain incompletely clarified and optimal management strategies need much further study.

RESUMEN

BACKGROUND AND AIMS: The influence of direct-acting antivirals (DAAs) on chronic hepatitis C (CHC)-related hepatocellular carcinoma (HCC) remains controversial. We investigated the effect of eradicating CHC using DAAs on treatment outcomes in patients with CHC-related HCC treated with transarterial chemoembolization (TACE). METHODS: This nationwide, multi-center, retrospective study recruited patients with CHC-related HCC treated with TACE as the first-line anti-cancer treatment, and who achieved a sustained virological response (SVR) using DAAs (DAA group) between 2006 and 2017. Patients achieving an SVR following interferon-based treatment (IFN group) and those without treatment (control group) were also recruited for comparison. RESULTS: A total of 425 patients were eligible for the study. Of these, 356 (83.8%), 26 (6.1%), and 43 (10.1%) were allocated to the control, IFN, and DAA groups, respectively. A multivariate analysis showed that liver cirrhosis, segmental portal vein thrombosis, and larger maximal tumor size independently predicted an increased risk of progression (all p < 0.05), whereas, the DAA group (vs. IFN and control groups) independently predicted a reduced risk of progression (hazard ratio (HR) = 0.630, 95% confidence interval 0.411-0.966, p = 0.034). The cumulative incidence rate of HCC progression in the DAA group was significantly lower than that in the IFN and control groups (p = 0.033, log-rank test). In addition, the DAA group (vs. IFN and control groups) was independently associated with a reduced risk of mortality (p = 0.042). CONCLUSIONS: DAA treatment provided significantly prolonged progression-free survival in patients with CHC-related HCC treated with TACE compared to that in patients administered IFN or no treatment.

RESUMEN

BACKGROUND: The advancement of treatment with direct-acting antiviral (DAA) agents has improved the cure rate of hepatitis C virus (HCV) infection close to 100%. The aim of our study was to assess the real-world effectiveness and safety of DAA regimens for the treatment of patients with chronic HCV genotype 2. METHODS: We retrospectively analyzed the clinical data of patients treated with sofosbuvir plus ribavirin (SOF + RBV) or glecaprevir/pibrentasvir (G/P) for chronic HCV genotype 2 infection at seven university hospitals in the Korean southeast region. RESULTS: SOF + RBV therapy produced an 89% and 98.3% sustained virologic response 12 week (SVR12) after treatment completion in the full analysis set and per-protocol set, respectively, and the corresponding values for G/P therapy were 89.5% and 99.2%, respectively. The difference between the treatments was probably because 6.2% (59/953) of patients in the SOF + RBV group did not complete the treatment and 9.8% (14/143) in the G/P group did not test HCV RNA after treatment completion. Adverse events (A/Es) were reported in 59.7% (569/953) and 25.9% (37/143) of the SOF + RBV and G/P groups, respectively. In the SOF + RBV group, 12 (1.26%) patients discontinued treatment owing to A/Es, whereas no patients discontinued treatment because of A/Es in the G/P group. CONCLUSION: In both treatment groups, SVR was high when treatment was completed. However, there was a high dropout rate in the SOF + RBV group, and the dropout analysis showed that these were patients with liver cirrhosis (LC; 43/285, 15.1%), especially those with decompensated LC (12/32, 37.5%). Therefore, an early initiation of antiviral therapy is recommended for a successful outcome before liver function declines. Furthermore, patients with decompensated LC who are considered candidates for SOF + RBV treatment should be carefully monitored to ensure that their treatment is completed, especially those with low hemoglobin and high alanine transaminase.

RESUMEN

BACKGROUND: Hepatocellular carcinoma (HCC) is an inflammation-related cancer, where nonresolving inflammation contributes to its development and progression. Peripheral inflammatory cells have been shown to be associated with the prognosis of various types of cancer. The present study investigated the utility of pretreatment peripheral inflammatory cells in the prognosis of patients with HCC. METHODS: We retrospectively analyzed data regarding peripheral inflammatory cell, and patient and tumor characteristics from patients with HCC who were diagnosed between November 2008 and March 2018. Baseline data, including peripheral inflammatory cell counts, were recorded before treatment. The relationships between overall survival (OS) and study variables were assessed. RESULTS: A total of 1681 patients who were diagnosed with HCC were included. In univariate and multivariate analyses, individual neutrophil, lymphocyte and monocyte cell counts were found as independent indicators of poor OS. High neutrophil (≥3100 × 106/L) and, monocyte (≥470 × 106/L) counts and low lymphocyte counts (< 1640 × 106/L) significantly associated with reduced OS (p < 0.05). Neutrophil and, monocyte cell counts rose and lymphocyte counts decreased in association with advancing the Barcelona Clinic Liver Cancer stage (P < 0.001). CONCLUSIONS: Pretreatment peripheral neutrophils, lymphocytes, and monocytes are independently associated with outcomes of patients with HCC. These cells provides a noninvasive, low-cost, easy, and reproducible biomarker that can be used in routine clinical practice to predict the prognosis of patients with HCC.

RESUMEN

PURPOSE OF REVIEW: Cirrhotic cardiomyopathy is a syndrome of depressed cardiac function in patients with cirrhosis. We aimed to review the historical background, pathophysiology and pathogenesis, diagnostic definitions, clinical relevance, and management of this syndrome. RECENT FINDINGS: An inflammatory phenotype underlies the pathogenesis: gut bacterial translocation with endotoxemia stimulates cytokines and cardiodepressant factors, such as nitric oxide and endocannabinoids. Cardiomyocyte plasma membrane biochemical and biophysical changes also play a pathogenic role. These factors lead to impaired beta-adrenergic function. Proposed new echocardiographic criteria for the diagnosis of cirrhotic cardiomyopathy include systolic global longitudinal strain and indices of diastolic dysfunction. Cardiac dysfunction participates in the pathogenesis of hepatorenal syndrome and increased morbidity/mortality of cirrhotic patients to hemorrhage, infection, and surgery, including liver transplantation. There is no specific treatment, although ß-adrenergic blockade and supportive management have been proposed, but it needs further study. Cirrhotic cardiomyopathy is a clinically relevant syndrome afflicting patients with established cirrhosis. Optimum management remains unclear, and further study is needed in this area.

RESUMEN

BACKGROUND & AIMS: There are no globally agreed upon treatment guidelines for patients with chronic hepatitis B virus (HBV) with multidrug resistance (MDR). We conducted a multicenter, prospective, real-world cohort study of effects of tenofovir disoproxyl fumarate (TDF) monotherapy and TDF-based combination therapy, as rescue therapy, in patients with multidrug-resistant chronic HBV infections. METHODS: We recruited patients with chronic HBV infection with resistance to antivirals from 8 tertiary hospitals in Korea. Patients (n=423) received rescue therapy with TDF monotherapy (n=174) or TDF-based combination therapy (n=249). The median follow-up period was 180 weeks. A virologic response was defined as a serum HBV DNA level of <20 IU/mL. RESULTS: Cumulative rates of virologic response did not differ significantly between the groups that received TDF monotherapy vs combination therapy at 48 weeks (71.7% vs 68.9%), 96 weeks (85.1% vs 84.2%), 144 weeks (92.1% vs 92.7%), 192 weeks (93.4% vs 95.7%), or 240 weeks (97.7% vs 97.2%). Serum levels of HBV DNA below 4.0 log10 IU/mL (odds ratio, 2.478; 95% CI 1.959-3.135; P < .001) and the absence of mutations associated with resistance to adefovir (odds ratio, 1.570; 95% CI 1.279-1.926; P < .001) were associated with virologic response in patients with MDR. There was no significant difference of virologic response among patients of different ages, sex, patients with vs without cirrhosis, positivity for hepatitis B e antigen, or renal function (all P > .05). CONCLUSION: In a multicenter, real-world cohort study, long-term use of TDF monotherapy showed non-inferior antiviral efficacy compared with that of TDF-based combination therapy in patients with MDR.

RESUMEN

Hepatitis B virus (HBV) suppression with nucleot(s)ide analogue therapy reduces the risk of hepatic decompensation and hepatocellular carcinoma (HCC) in patients with advanced liver disease.1 In the present era of potent antiviral therapies, the prognostic significance of the serum HBV DNA level as a biological gradient has substantially diminished; the majority of treated patients achieve virologic suppression.2,3 After control of viremia, a higher baseline fibrosis level is a useful predictor for disease progression.4 Few "prospective" studies on the effects of antiviral agents, especially in chronic hepatitis B (CHB) patients with advanced liver disease, have been reported.

RESUMEN

BACKGROUND & AIMS: Tenofovir alafenamide (TAF) is a new prodrug of tenofovir developed to treat patients with chronic hepatitis B virus (HBV) infection at a lower dose than tenofovir disoproxil fumarate (TDF) through more efficient delivery of tenofovir to hepatocytes. In 48-week results from two ongoing, double-blind, randomized phase III trials, TAF was non-inferior to TDF in efficacy with improved renal and bone safety. We report 96-week outcomes for both trials. METHODS: In two international trials, patients with chronic HBV infection were randomized 2:1 to receive 25 mg TAF or 300 mg TDF in a double-blinded fashion. One study enrolled HBeAg-positive patients and the other HBeAg-negative patients. We assessed efficacy in each study, and safety in the pooled population. RESULTS: At week 96, the differences in the rates of viral suppression were similar in HBeAg-positive patients receiving TAF and TDF (73% vs. 75%, respectively, adjusted difference -2.2% (95% CI -8.3 to 3.9%; p = 0.47), and in HBeAg-negative patients receiving TAF and TDF (90% vs. 91%, respectively, adjusted difference -0.6% (95% CI -7.0 to 5.8%; p = 0.84). In both studies the proportions of patients with alanine aminotransferase above the upper limit of normal at baseline, who had normal alanine aminotransferase at week 96 of treatment, were significantly higher in patients receiving TAF than in those receiving TDF. In the pooled safety population, patients receiving TAF had significantly smaller decreases in bone mineral density than those receiving TDF in the hip (mean % change -0.33% vs. -2.51%; p <0.001) and lumbar spine (mean % change -0.75% vs. -2.57%; p <0.001), as well as a significantly smaller median change in estimated glomerular filtration rate by Cockcroft-Gault method (-1.2 vs. -4.8 mg/dl; p <0.001). CONCLUSION: In patients with HBV infection, TAF remained as effective as TDF, with continued improved renal and bone safety, two years after the initiation of treatment. Clinicaltrials.gov number: NCT01940471 and NCT01940341. LAY SUMMARY: At week 96 of two ongoing studies comparing the efficacy and safety of tenofovir alafenamide (TAF) to tenofovir disoproxil fumarate (TDF) for the treatment of chronic hepatitis B patients, TAF continues to be as effective as TDF with continued improved renal and bone safety. Registration: Clinicaltrials.gov number: NCT01940471 and NCT01940341.

RESUMEN

Early recurrence is common after curative hepatectomy for hepatocellular carcinoma and is associated with poor prognosis. This study aimed to identify risk factors of early recurrence after curative hepatectomy in hepatocellular carcinoma. Overall, 63 patients who underwent curative hepatectomy for hepatocellular carcinoma were enrolled. Patients were divided into the early recurrence group, who developed recurrence within 12 months after hepatectomy (n = 10), and the non-early recurrence group (n = 53). Clinicopathological factors of early recurrence were retrospectively analyzed. Among the 63 patients, 10 (15.9%) patients experienced early recurrence. Univariate analysis showed tumor necrosis (p = 0.012), level of PIVKA-II (prothrombin induced by vitamin K absence or antagonist-II; p = 0.002), and microvascular invasion (p = 0.029) to be associated with early recurrence. By multivariate analysis, there were significant differences in high PIVKA-II (p < 0.001) and tumor necrosis (p = 0.012) in patients with early recurrence. The optimal cutoff values of PIVKA-II and tumor necrosis were 46 mAU/mL and 3% of total tumor volume, respectively. Patients with a high preoperative PIVKA-II level and extent of tumor necrosis, which are independent risk factors for early recurrence, should be actively treated and monitored closely after hepatectomy.

RESUMEN

AIM: The aim of this study was to investigate the effect of yttrium-90 radioembolization on the outcome of Asian patients with early to advanced stage hepatocellular carcinoma (HCC). METHODS: Sixty-two patients were screened and 50 patients (80.6%) were eligible. Response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST), and overall survival was estimated using the Kaplan-Meier method. RESULTS: The Barcelona Clinic Liver Cancer (BCLC) stage was A in 40% of patients, B in 24%, and C in 36%; 66% of patients had hepatitis B virus infections. According to RECIST criteria, partial responses occurred in 40% of patients, and stable disease was achieved in 46%. Tumor response was significantly associated with BCLC stage (P = 0.003). The median overall time to progression was 5.8 months (range, 0.9-46.1 months). Follow-up treatments after radioembolization were carried out in 31 patients due to remnant HCC (n = 18) or HCC progression (n = 13). The median overall survival was 40.9 months (95% confidence interval, 10.2-71.6 months). Treatment was tolerable except for one lung toxicity and two hepatic toxicities. CONCLUSION: Yttrium-90 radioembolization appears to be well tolerated and effective in Asian patients with BCLC stage A-C HCC. Follow-up treatments after radioembolization can be safely provided.

RESUMEN

BACKGROUND AND AIM: This multinational (Taiwan, South Korea, Russia) phase 3 study evaluated the all-oral, ribavirin-free, fixed-dose combination (DCV-TRIO) of daclatasvir (NS5A inhibitor) 30 mg, asunaprevir (NS3 inhibitor) 200 mg, and beclabuvir (NS5B inhibitor) 75 mg, in patients with chronic hepatitis C virus genotype-1 infection, with or without compensated cirrhosis. METHODS: UNITY-4 (NCT02170727) was an open-label, two-cohort study in which 169 patients, treatment-naive (n = 138) or treatment-experienced (n = 31), received twice-daily DCV-TRIO for 12 weeks with 24 weeks of post-treatment follow-up. The primary efficacy end point was sustained virologic response at post-treatment week 12 (SVR12) in treatment-naive patients. RESULTS: Eighty-eight (52%) patients were men, 81 (48%) Taiwanese, 78 (46%) Korean, and 10 (6%) Russian; 23 (14%) had compensated cirrhosis, and 52 (31%) were IL28B (rs1297860) non-CC genotype. Baseline resistance-associated NS5A polymorphisms (L31 and/or Y93) were detected in 25/165 (15%) patients with available genotype-1 sequencing data. SVR12 was achieved by 98.6% (136/138; 95% confidence interval: 94.9-99.8%) of treatment-naive and 100% (31/31; 95% confidence interval: 88.8-100%) of treatment-experienced patients. Both virologic failures were found to be infected with hepatitis C virus genotype-6g; 100% SVR12 was observed for genotype-1a (n = 8) and genotype-1b (n = 157). Two patients experienced serious adverse events. Eight (5%) patients experienced reversible grade 3/4 alanine aminotransferase or aspartate aminotransferase elevations, leading to discontinuation in four (2%); all achieved SVR12. There were no grade 3/4 total bilirubin increases and no deaths. CONCLUSIONS: Twelve weeks of DCV-TRIO was well tolerated and provided 100% SVR12 in treatment-naive and treatment-experienced patients with genotype-1 infection, with or without cirrhosis, including those with baseline NS5A-L31 or NS5A-Y93 resistance-associated substitutions.

RESUMEN

BACKGROUND AND AIM: There are limited data assessing whether patients who achieved virological suppression on lamivudine but remain hepatitis B "e" antigen-positive should be switched to a more potent antiviral with a high genetic barrier to resistance or continue with lamivudine. We compared the safety and efficacy of switching with entecavir versus continuing lamivudine. METHODS: This was a Phase IV, randomized, open-label, prospective study in a tertiary care setting. Seventy-three chronic hepatitis B patients who achieved virological suppression on lamivudine (serum hepatitis B virus DNA < 60 International Unit (IU)/mL) were enrolled. Entecavir or lamivudine were administered orally for up to 96 weeks. Virologic and serologic responses were measured throughout the study. RESULTS: A significantly higher proportion of patients in the entecavir group achieved hepatitis B virus DNA < 60 IU/mL at Weeks 48 (100% [38/38] vs 62.8% [22/35]; P < 0.001) and 96 (97.4% [37/38] vs 57.1% [20/35]; P<0.001). A greater number of patients had virologic breakthrough (Week 96 cumulative incidence 42.9% vs 2.6%; P<0.001) and genotypic lamivudine resistance (28.6% [10/35] vs 0% [0/38]; P<0.001) in the lamivudine group. No serious adverse events or laboratory abnormalities were reported. CONCLUSIONS: Even after achieving virological suppression on lamivudine therapy, the risk of emergent lamivudine resistance increases over time. Switching to entecavir resulted in a maintained virologic response and superior serologic responses versus continued lamivudine therapy. This study supports a rationale for switching to entecavir in chronic hepatitis B patients with virological suppression on lamivudine.

RESUMEN

Multiple therapeutic modalities are available for hepatocellular carcinoma (HCC) treatment. We aimed to evaluate the trends for HCC treatment in Korea. Recent trends and patterns in treatment modalities were assessed in HCC patients who first registered for the Health Insurance Review Assessment Service between 2008 and 2012. From 2009 to 2012, 57,690 patients were diagnosed with HCC. Transcatheter arterial chemoembolization (TACE) was the most common treatment modality for initial treatment. Curative treatment modalities like hepatic resection, liver transplantation, and local ablation therapy increased gradually. The 3 most common treatment modalities (hepatic resection, local ablation therapy, TACE) used after initial treatment in 2009 were studied. Following initial hepatic resection, 44.5% of patients required re-treatment. TACE was the most common modality (in 48.3% of cases), while 15.0% of patients received local ablation therapy. After local ablation therapy, 55.4% of patients were re-treated, wherein 45.0% of patients received TACE and 31.5% received local ablation therapy. Following initial TACE, 73.9% patients were re-treated, most commonly with TACE (57.7%) followed by local ablation therapy (12.8%). While there were no significant differences between the initial and re-treatment modalities, various multiple treatments followed the initial treatment. The treatment modalities were interchangeable.

RESUMEN

Analgesics, known to be hepatotoxic drugs, are frequently prescribed to patients with liver cirrhosis who are prone to drug-induced liver injury. No guidelines are available regarding the prescription of analgesics in these patients. Therefore, we aimed to evaluate the prescription pattern of most frequently used analgesics in patients with cirrhosis. We assessed the prescription pattern of acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) in patients with liver cirrhosis registered in Health Insurance Review Assessment Service database between January 1, 2012 and December 31, 2012. A total of 125,505 patients with liver cirrhosis were registered from January 1, 2012 to December 31, 2012. Of that group, 50,798 (40.5%) patients claimed reimbursement for at least one prescription for acetaminophen or NSAIDs during the one year follow-up period. Overall, NSAIDs (82.7%) were more prescribed than acetaminophen (64.5%). NSAIDs were more prescribed than acetaminophen even in decompensated cirrhosis compared with compensated cirrhosis (71.5% vs. 68.8%, P value < 0.001). There was a marked difference in prescription preference between acetaminophen and NSAIDs among physicians. Internists more frequently prescribed acetaminophen than NSAIDs compared to other physicians (50.9% vs. 76.2%, P < 0.001). Gastroenterologists more frequently prescribed acetaminophen over NSAIDs compared to other internists (80.9% vs. 51.2%, P < 0.001). Analgesics were prescribed in 40.5% of patients with cirrhosis. NSAIDs were more frequently prescribed although they should be avoided. The prescription pattern of analgesics were different significantly among physicians in patients with liver cirrhosis. The harmful effects of NSAIDs in patients with cirrhosis should be reminded to all physicians prescribing analgesics.
