Abstract
BACKGROUND AND AIM Lack of awareness disturbs proper care for hepatitis C virus (HCV) infections in patients undergoing surgery. We investigated the status of HCV screening, confirmation, and treatment in patients who underwent surgery. METHODS Patients who underwent surgery at a tertiary academic center between 2019 and 2021 were eligible for this retrospective study. RESULTS Between 2019 and 2021, 96 894 patients (40 121 males; 41.4%) who underwent surgery under general anesthesia were recruited. The median age of the participants was 55.0 years. Of the 83 920 (86.6%) patients who tested positive for anti-HCV antibodies, 576 (0.7%) showed positive results, with a higher proportion of patients with diabetes mellitus (32.6% vs 18.5%), hypertension (50.5% vs 28.6%), liver cirrhosis (13.2% vs 1.7%), and unfavorable laboratory test results when compared with those with negative results (all P < 0.05). HCV RNA was tested in 215 patients (37.3%), with a positivity rate of 20.5% (n = 44). Of the 44 patients, 42 (95.5%) were referred for antiviral treatment, and 29 (69.0%) were successfully treated with direct-acting antiviral therapy. HCV RNA confirmation rates were higher in the Department of Hepatobiliary and Transplant Surgery (76.6%) than in the other surgical departments (25.0-33.5%) (P < 0.001). CONCLUSIONS The proportion of patients who were positive for anti-HCV antibodies and failed to receive proper management after surgery was not negligible. Increased awareness of HCV infection among surgeons through appropriate education may be required.

Abstract
BACKGROUND Limited data are available on hepatitis C virus (HCV) infection in persons who inject drugs (PWID) in South Korea. The present study aimed to investigate the seroprevalence of HCV antibodies, risk factors for HCV seropositivity, and HCV treatment status in PWID between January 2012 and May 2022. METHODS We retrospectively reviewed the medical records of 418 drug users who underwent HCV antibody testing in three hospitals caring for 90% of known PWID in South Korea, of whom 373 were PWID. RESULTS The HCV seroprevalence was 39.7% (148/373) in PWID vs. 6.7% (3/45) in non-injection drug users (P < 0.001). Age ≥ 40 years, hospital type (58.2% in the prison hospital vs. 34.0% in the private hospital), and enrollment year (68.2% in 2012-2014 vs. 30.0% in 2021-2022) were independently associated with HCV seropositivity. Among the HCV-seropositive PWID, 90.5% (134/148) were diagnosed with HCV infection; however, only 6.8% (10/148) received HCV treatment. The hepatitis B virus surface antigen and human immunodeficiency virus antibody positivity were 4.0% (14/352) and 1.9% (6/317) in tested PWID, respectively. CONCLUSION The HCV seroprevalence in PWID was 39.7% with a very low treatment rate, which prompts active measures to test and treat PWID for HCV infection in South Korea.

J Clin Med 2022; 11:jcm11051451. [PMID: 35268541 PMCID: PMC8911386 DOI: 10.3390/jcm11051451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 03/05/2022] [Accepted: 03/06/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Hepatocellular carcinoma (HCC) rarely develops in patients with chronic hepatitis C (CHC) who achieve sustained virological response (SVR). We assessed the incidence of HCC in CHC patients with hemophilia after treatment with pegylated interferon plus ribavirin (PegIFN/RBV) and direct-acting antivirals (DAAs). Methods: Patients (n = 202) were enrolled between March 2007 and July 2019. A total of 139 patients were treated with PegIFN/RBV (genotype 1, n = 98; genotype 2, n = 41). Sixty-three patients were treated with DAAs (genotype 1, n = 44; genotype 2, n = 19). The cumulative incidence rates of HCC were estimated using the Kaplan−Meier method and compared using the log-rank test. Results: For genotype 1, SVR was achieved in 78.6% (77/98) and 90.9% (40/44) of patients in the PegIFN/RBV and DAAs groups, respectively. For genotype 2, SVR was achieved in 95.1% (39/41) and 94.7% (18/19) of patients in the PegIFN/RBV and DAAs groups, respectively. Six HCC cases were identified. The cumulative incidence of HCC was 4.1% at 14 years in PegIFN/RBV and 1.7% at 5 years in DAAs. The 14-year cumulative incidence of HCC was 1.9% in the SVR group and 21.7% in the no-SVR group in the PegIFN/RBV group (p < 0.001). Conclusions: Treatment with PegIFN/RBV led to stable SVR and a low incidence of HCC. Although the follow-up period was short, DAAs led to more stable SVR than PegIFN/RBV and a low incidence of HCC in CHC patients with hemophilia.

Abstract
Hepatitis C virus (HCV) is a significant public health problem, and the elimination of its infection by 2031 is a global goal. However, due to insufficient testing, lack of linkage to care (LTC) and treatment, Libya may be far from achieving this goal. This study aimed to explore HCV testing, the care and treatment of infected people, and to assess the burden of the infection among individuals who visited the main Medical Centre in Tobruk region, eastern Libya, for various medical and surgical conditions. A research team interviewed public health officials in Tobruk Medical Center, inspected available equipment, and obtained data available for people who were positive for antibodies to HCV (anti-HCV) as part of their routine pre-invasive procedures and pre-donation screening tests from January 2005 to April 2020. HCV antibody tests were positive for 612 cases out of 368,392 (0.17%). Of those who tested positive for anti-HCV antibodies, no one had followed up by RNA test for identifying individuals with chronic HCV infection, and there are no links to outpatient care and treatment. Our findings highlight the critical need for an up-to-date HCV diagnosis and linkage to care guidelines, which includes a follow-up RNA test for anti-HCV positive patients and early linkage to care for confirmed cases to accelerate the elimination of HCV infection from the community.

Abstract
Hepatitis C virus (HCV) infection is the second most common cause of chronic liver disease in South Korea, with a prevalence ranging from 0.6% to 0.8%, and HCV infection incidence increases with age. The anti-HCV antibody test, which is cheaper than the HCV RNA assay, is widely used to screen for HCV infections; however, the underdiagnosis of HCV is a major barrier to the elimination of HCV infections. Although several risk factors have been associated with HCV infections, including intravenous drug use, blood transfusions, and hemodialysis, most patients with HCV infections present with no identifiable risk factors. Universal screening for HCV in adults has been suggested to improve the detection of HCV infections. We reviewed the cost-effectiveness of HCV screening and the methodologies used to perform screening. Recent studies have suggested that universal HCV screening and treatment using direct-acting antivirals represent cost-effective approaches to the prevention and treatment of HCV infection. However, the optimal timing and frequency of HCV screening remain unclear, and further studies are necessary to determine the best approaches for the elimination of HCV infections.

Abstract
BACKGROUND AND AIM Several barriers prevent the proper screening, diagnosis, and treatment of hepatitis C virus (HCV) infection. We aimed to evaluate the status of HCV screening, confirmation, and treatment rates in a tertiary academic medical center in Korea. METHODS Patients who visited Severance Hospital between 2015 and 2019 were eligible in this retrospective study. The testing and positivity rates for anti-HCV antibodies and HCV RNA were sequentially analyzed. RESULTS Between 2015 and 2019, 252 057 patients (117 131 men, 46.5%) who underwent anti-HCV antibody testing were retrospectively reviewed. The median age of the study population was 51.0 years. Patients with positive anti-HCV antibody test results (n = 2623, 1.0%) showed a higher proportion of liver cirrhosis (17.6% vs 2.0%) and unfavorable laboratory test results (all P < 0.05). The positivity rates were 1.3% and 0.8% in the medical and surgical departments, respectively. HCV RNA was tested in 1628 (62.1%) patients, with a 57.4% (n = 928) positivity rate. The medical department had a higher HCV RNA testing rate than the surgical department (75.4% vs 40.8%). Among the 928 patients who showed positivity for HCV RNA, 847 (90.7%) underwent genotype testing (mostly 1 and 2 [95.4%]). The treatment rate was 66.9% (n = 567); it was higher in the gastroenterology department (70.8%) than in the non-gastroenterology departments (62.3%). CONCLUSIONS A considerable proportion of patients testing positive for anti-HCV antibodies were not referred for proper management. Systematic and automated screening and referral systems, which may help identify patients requiring treatment for HCV infection, are necessary even in tertiary academic medical centers.

Abstract
Background/Aims Sofosbuvir (SOF)-based therapy has been used in Korean patients with chronic hepatitis C virus (HCV) infection since January 2016. This study aimed to investigate the real-life effectiveness and safety of SOF-based therapy in genotype 2 HCV infection. Methods From January to December 2016, 458 genotype 2 HCV-infected patients who received ≥1 dose of SOF-based therapy were consecutively enrolled in seven tertiary hospitals. Sustained virologic response (SVR) rates and safety were determined by intention- to-treat (ITT) and per-protocol (PP) analyses. Results The mean age of the patients was 61.0 years; 183 (40%) were male, and 13.1% showed a high viral load (>6,000,000 IU/ mL). Among the 378 treatment-naïve patients, the SVR rates were 94.2% (ITT) and 96.7% (PP). Among the 80 treatmentexperienced patients, the SVR rates were 96.3% (ITT) and 98.7% (PP). Patients with a relatively high fibrosis-4 index score (>3.25) had similar SVR rates to those with a relatively low score (p=0.756). A total of 314 patients (68.6%) were treated with a reduced ribavirin dose at the prescriber's discretion, but they showed similar SVR rates to those treated with the weight-based dose (ITT: 95.5% and 92.3%, PP: 97.4% and 96.3%, respectively). Adverse events were observed in 191 patients (41.7%), including 86 (18.8%) with anemia, but only one (0.2%) discontinued antiviral therapy due to nausea. Conclusions SOF-based therapy showed high real-life efficacy and tolerability in Korean patients with genotype 2 chronic HCV infection, regardless of previous antiviral treatment experience and fibrosis score. A reduced ribavirin dose can be considered in this patient cohort.

Abstract
Background/Aims To eliminate hepatitis C virus (HCV) infection, improving public knowledge of and access to HCV screening and treatment is essential. The aim of this study was to evaluate the knowledge of and testing rate for HCV and the opinions about the inclusion of the HCV test in the National Health Examination (NHE) among the general population in South Korea. Methods A telephone interview survey was conducted by an independent research company using a 16 item-questionnaire (demographics, knowledge of HCV, testing and results, need for screening) in May 2019. The sample population consisted of 1,003 adult Korean residents adjusted by age, sex, and area according to the standard Korean population in 2019. Results Among the 1,003 participants (505 women, mean age of 47.9 years), 56.4% recognized HCV; 44.4% understood that HCV is transmittable, and 56.8% thought that HCV is curable by medication. The recognition rate tended to increase with an increasing level of education. Testing for anti-HCV antibodies was reported by 91 people (9.1%); among them, 10 people (11.0%) reported a positive result, and eight people received treatment. The common reasons for HCV testing were a health check-up (58.5%), a physician's recommendation (11.0%) and elevated liver enzyme levels (10.7%). The majority of the population (75.1%) agreed with the integration of HCV into the NHE. Conclusions The level of knowledge of HCV is suboptimal, and the self-reported testing rate for HCV is less than 10%; however, once HCV infection is diagnosed, the treatment rate seems to be high in South Korea. More active campaigns and effective screening are needed.

[PMID: 34060258 PMCID: PMC8167412 DOI: 10.3346/jkms.2021.36.e142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Accepted: 04/25/2021] [Indexed: 11/20/2022] Open
Abstract
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.

Real-Life Effectiveness and Safety of Glecaprevir/Pibrentasvir for Korean Patients with Chronic Hepatitis C at a Single Institution. Gut Liver 2021; 15:440-450. [PMID: 32839365 PMCID: PMC8129668 DOI: 10.5009/gnl19393] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 06/03/2020] [Accepted: 06/21/2020] [Indexed: 12/14/2022] Open
Abstract
Background/Aims Glecaprevir/pibrentasvir (G/P) is a combination of direct-acting antiviral agents that is an approved treatment for chronic infections by all six hepatitis C virus (HCV) genotypes. However, there are limited data on the effect of G/P in Korean patients in actual real-world settings. We evaluated the real-life effectiveness and safety of G/P at a single institution in Korea. Methods This retrospective, observational, cohort study used sustained virologic response at 12 weeks after treatment completion (SVR12) as the primary effectiveness endpoint. Safety and tolerability were also determined. Results We examined 267 individuals who received G/P for chronic HCV infections. There were 148 females (55.4%), and the overall median age was 63.0 years (range, 25 to 87 years). Eighty-three patients (31.1%) had HCV genotype-1 and 182 (68.2%) had HCV-2. A total of 212 patients (79.4%) were HCV treatment-naïve, 200 (74.9%) received the 8-week treatment, 13 (4.9%) had received prior treatment for hepatocellular carcinoma, 37 (13.7%) had chronic kidney disease stage 3 or higher, and 10 (3.7%) were receiving dialysis. Intention to treat (ITT) analysis indicated that 256 (95.9%) achieved SVR12. A modified ITT analysis indicated that SVR12 was 97.7% (256/262). Six patients failed therapy because of posttreatment relapse. SVR12 was significantly lower in those who received prior sofosbuvir treatment (p=0.002) and those with detectable HCV RNA at week 4 (p=0.027). Seventy patients (26.2%) experienced one or more adverse events, and most of them were mild. Conclusions These real-life data indicated that G/P treatment was highly effective and well tolerated, regardless of viral genotype or patient comorbidities. (Gut Liver 2021;15-450)

Abstract
BACKGROUND/AIMS Real-world, clinical practice data are lacking about sofosbuvir/ ribavirin (SOF/RBV) treatment of Korean patients with hepatitis C virus genotype 2 (HCV GT2) infection. This study investigated the efficacy and safety of SOF/RBV in Korean patients with HCV GT2 infection and clinical factors predicting sustained virological response 12 weeks (SVR12) after the end of SOF/RBV treatment. METHODS A total of 181 patients with HCV GT2 with/without cirrhosis were treated with SOF/RBV for 16/12 weeks. Rapid virological response (RVR) was defined as non-detectable HCV RNA at 4 weeks. RESULTS The RVR rate was 80.7% (146/181), the end of treatment response rate was 97.8% (177/181) and the SVR12 rate was 92.8% (168/181). Of eight patients with relapse, four did not achieve RVR. Three patients had a history of hepatocellular carcinoma (HCC). Multivariable analysis showed that RVR (p = 0.015) and no previous history of HCC (p = 0.007) were associated with SVR12. Factors significantly contributing to RVR included cirrhosis, creatinine concentration, and pre-treatment HCV RNA level. SVR12 rate was significantly higher in RVR (+) than RVR (-) patients (95.2% vs. 82.9%, p = 0.011) and also significantly higher in patients without than with a history of HCC (94.1% vs. 72.7%, p = 0.008). During treatment, 80/181 patients (44.2%) experienced mild to moderate adverse events, with 32 (17.7%) requiring RBV dose reductions due to anemia. CONCLUSION SOF/RBV treatment was effective and tolerable in HCV GT2 patients. RVR and no previous history of HCC were positive predictors of SVR12.

Abstract
Background The opportunities for examining elderly patients with hepatocellular carcinoma (HCC) have increased. We investigated the treatment of HCC for elderly patients and the overall survival associated with each treatment modality. Methods From January 2003 to December 2005 (n=578, period I) and January 2008 to December 2014 (n=2428, period II), the National Cancer Center and Korean Liver Cancer Association collected clinical data of 3006 patients with HCC aged ≥70 years old at 54 medical centers in Korea. We analyzed the treatment modalities and overall survival for patients with HCC aged ≥70 years. Results The mean age, Child-Pugh score, and model for end-stage liver disease score and proportion of male patients were not different between period I and period II (74 years, 6.6, 10.4 and 70.1% vs 76 years, 6.2, 9.9 and 67.3%). TNM stage II and BCLC stage A were most commonly noted in periods I and II (44.3% and 49.1% vs 40.4% and 40.2%). Transarterial therapy was the most commonly used treatment modality according to age in both periods. Surgical resection was associated with significant superior overall survival compared to local ablation and transarterial therapy (p<0.001). After propensity score matching between surgical resection and transarterial therapy in period II, surgical resection was associated with more favorable overall survival outcomes (median: 39 months vs 86 months, p<0.001). Conclusion Transarterial therapy was the most commonly used treatment modality for patients with HCC aged ≥70 years. However, surgical resection led to significantly higher overall survival rates compared to other treatment modalities.

Abstract
BACKGROUND/AIM This study aimed to establish the real-world effectiveness and safety of grazoprevir/elbasvir (EBR/GZR) therapy in South Korea. METHODS A total of 242 patients with chronic hepatitis C virus (HCV) genotype 1 or 4 infection who started EBR/GZR were consecutively enrolled from seven tertiary hospitals. Retrospective analysis of the fractions of patients that achieved sustained virological response (SVR) was performed, and the incidence of adverse events was noted. RESULTS The mean age of enrolled patients was 59.0 ± 12.6 years and 47.5% were males. Patients with HCV genotype 1b accounted for 93.8% (n = 227), and patients with HCV of unspecified genotype 1 accounted for 5.8% (n = 14). Hypertension was the most common comorbid disease (29.8%) followed by diabetes (22.7%) and chronic kidney disease (CKD, 12.4%). SVR rates of treatment-naïve and treatment-experienced patients were 85.5% (182/213) and 93.1% (27/29), respectively, in the intention-to-treat analyses, whereas in the per-protocol analyses, those were 97.8% (179/183) and 100% (28/28), respectively. Fewer patients with HCV genotype 1 of unspecified subtype achieved SVR (81.8%, n = 11) compared to the patients with SVR infected with genotype 1b (99%, n = 198, p < 0.001). All patients with CKD showed SVR. Itching (12%) and dyspepsia (4.1%) were common adverse events. Of the four patients who discontinued the antiviral therapy, one experienced mild fatigue but neither treatment withdrawal was because of an adverse event. CONCLUSION EBR/GZR showed high real-world effectiveness and safety in Korean patients with chronic HCV infection regardless of the previous antiviral treatment, liver cirrhosis, or CKD status.

Abstract
Background/Aims This study aimed to elucidate the epidemiological and clinical characteristics of chronic hepatitis C (CHC) patients in South Korea from 2007 to 2017 and to compare the treatment patterns between two periods before and after the first approval of direct-acting antivirals (DAA) in South Korea in 2015. Methods This prospective, multicenter cohort enrolled 2,758 patients with hepatitis C virus (HCV) viremia at seven tertiary centers, and clinical data were prospectively collected with questionnaire surveys focused on lifetime risk factors related to HCV infection. Results The HCV patients had a mean age of 57.3 years (50.8% male). Among them, 14.3% showed a positive history of transfusion before HCV screening and 5.6% reported intravenous drug use (IVDU), with significant differences in these risk factors between men and women. The proportions of patients with chronic hepatitis, liver cirrhosis and hepatocellular carcinoma (HCC) were 69.5%, 18.9%, and 11.5%, respectively. The mean alanine aminotransaminase level was within the upper normal limit at 49.9%, and the major genotypes were 1b (48.2%) and 2 (46.4%). The overall treatment rate was 53.8%, showing a rapid transition from interferon-based therapy to DAA therapy. In the post-DAA-approval era, the untreated group was older, had a higher prevalence of HCC, and had less education than the treated group. Conclusions More than 90% of CHC patients were over 40 years old, the major genotypes were 1b and 2, and IVDU was observed in less than 6% of CHC patients. Approximately half of the patients underwent antiviral therapy even in the DAA era, showing an unmet need with regard to HCV elimination.

Abstract
Viral hepatitis is the most important cause of acute and chronic liver disease in Korea. Particularly, hepatitis B virus (HBV) is the leading cause of liver-related mortality. Because of the nationwide vaccinations in the 1980s, hepatitis B surface antigen positive rates substantially decreased from 8% to 3%. Moreover, the introduction of potent nucleoside or nucleotide analogs led to the effective treatment of patients who had already been infected by HBV. The remaining issue has been to develop novel drugs that can cure HBV infection. Hepatitis C virus (HCV), on the other hand, is a hepatotropic virus that is parenterally transmitted. In Korea, the prevalence of HCV is estimated to be approximately 1%. Although no effective vaccine for HCV has been developed yet, highly effective and safe direct-acting antiviral therapy, which has a short treatment duration of 8 - 12 weeks, has made HCV eradication possible globally. Currently, the unsolved issue regarding HCV management is low disease awareness among patients and health care providers. Therefore, nationwide testing for anti-HCV would be a solution to identify patients infected with HCV but with no symptoms. Lastly, the Hepatitis A virus (HAV) is orally transmitted and results in acute hepatitis. In Korea, the young adult population is a high-risk group since this group is not vaccinated against HAV. More active vaccination and improved hygiene would be necessary to prevent HAV infection.

Abstract
BACKGROUND AND STUDY AIMS The demand for treatments for viral hepatitis using direct antiviral agents (DAAs) has increased; however, few real-world clinical studies are available. The objective of this study was to evaluate the efficacy and safety of sofosbuvir combined with ribavirin for patients with chronic hepatitis C (CHC) genotype 2 (GT2). PATIENTS AND METHODS A total of 106 consecutive CHC GT2 patients treated with sofosbuvir plus ribavirin between May 2016 and August 2018 (median age: 52.5 years, male: 51 [48.1%], treatment-naïve patients: 98 [92.5%]) were analyzed. The primary endpoint was sustained virologic response at 12 weeks (SVR12). The secondary endpoint was the occurrence of side effects during treatment. RESULTS Of a total of 106 patients with CHC GT2, 103 were genotype 2a (97.2%), and 3 were 2b (2.8%). SVR12 was confirmed in 105 of 106 patients (99.1%). The one patient with treatment failure had combined liver cirrhosis and hepatocellular carcinoma. Twenty-five patients had liver cirrhosis in addition to hepatitis C virus (HCV) (Child-Turcotte-Pugh (CTP)-A, n = 24; C, n = 1), and SVR12 was confirmed in 24 of these patients (96.0%). The mean HCV RNA titer was 2,629,159 IU/ml. Reductions in haemoglobin levels occurred in 23 patients during treatment (3.0 mg/dL, mean), and consequently, ribavirin dose reduction was required (365.2 mg, mean). CONCLUSION Sofosbuvir plus ribavirin was highly effective for the treatment of patients with CHC GT2 and had no serious, treatment-related adverse effects.

Abstract
BACKGROUND Spatial epidemiology is used to evaluate geographical variations and disparities in health outcomes; however, constructing geographic statistical models requires a labor-intensive process that limits the overall utility. We developed an open-source software for spatial epidemiological analysis and demonstrated its applicability and quality. METHODS Based on standardized geocode and observational health data, the Application of Epidemiological Geographic Information System (AEGIS) provides two spatial analysis methods: disease mapping and detecting clustered medical conditions and outcomes. The AEGIS assesses the geographical distribution of incidences and health outcomes in Korea and the United States, specifically incidence of cancers and their mortality rates, endemic malarial areas, and heart diseases (only the United States). RESULTS The AEGIS-generated spatial distribution of incident cancer in Korea was consistent with previous reports. The incidence of liver cancer in women with the highest Moran's I (0.44; p < 0.001) was 17.4 (10.3-26.9). The malarial endemic cluster was identified in Paju-si, Korea (p < 0.001). When the AEGIS was applied to the database of the United States, a heart disease cluster was appropriately identified (p < 0.001). CONCLUSIONS As an open-source, cross-country, spatial analytics solution, AEGIS may globally assess the differences in geographical distribution of health outcomes through the use of standardized geocode and observational health databases.

Abstract
Background/Aims This study aimed to investigate the epidemiology of hepatitis C virus (HCV) infection in the Korean general population and the awareness and treatment status of HCV infection among anti-HCV-positive persons. Methods We used data from the Korea National Health and Nutrition Examination Survey (KNHNES) collected between 2012 and 2016. All the participants aged ≥10 years in the KNHNES were tested for the anti-HCV antibody. Anti-HCV-positive persons were tested for HCV RNA and assessed for their awareness and treatment experience regarding HCV infection. Results The prevalence of anti-HCV was 0.66% (95% confidence interval, 0.56% to 0.78%) among Koreans aged ≥10 years, representing an estimated 278,819 anti-HCV-positive persons, and 0.71% (95% confidence interval, 0.60% to 0.84%) among Koreans aged ≥20 years. The prevalence of anti-HCV increased with age and had significant geographic variation. The positive rate of HCV RNA in anti-HCV-positive persons was 33.5% and increased with age. The rate of HCV infection awareness was 15.2% (35/250) among anti- HCV-positive persons and 30.5% (18/59) among HCV RNApositive persons. Among the participants, 13.5% of HCV RNA-positive persons had been treated for HCV infection. Conclusions The prevalence of anti-HCV among Koreans aged ≥20 years was 0.71%; one-third of anti-HCV-positive persons tested HCV RNA-positive. The awareness and treatment rates of HCV infection were low among HCV-infected persons. Therefore, active measures should be taken to diagnose and treat persons unaware of HCV infection.

Abstract
BACKGROUND Liver cirrhosis has become a heavy burden not only for patients, but also for our society. However, little is known about the recent changes in clinical outcomes and characteristics of patients with cirrhosis-related complications in Korea. Therefore, we aimed to evaluate changes in characteristics of patients with liver cirrhosis in Daegu-Gyeongbuk province in Korea over the past 15 years. METHODS We retrospectively reviewed the medical records of 15,716 liver cirrhotic patients from 5 university hospitals in Daegu-Gyeongbuk province from 2000 to 2014. The Korean Standard Classification of Diseases-6 code associated with cirrhosis was investigated through medical records and classified according to the year of first visit. RESULTS A total of 15,716 patients was diagnosed with cirrhosis. A number of patients newly diagnosed with cirrhosis has decreased each year. In 2000, patients were most likely to be diagnosed with hepatitis B virus (HBV) cirrhosis, followed by alcoholic cirrhosis. There was a significant decrease in HBV (P < 0.001), but alcohol, hepatitis C virus (HCV), and non-alcoholic fatty liver disease (NAFLD) showed a significant increase during the study period (alcohol, P = 0.036; HCV, P = 0.001; NAFLD, P = 0.001). At the time of initial diagnosis, the ratio of Child-Turcotte-Pugh (CTP) class A gradually increased from 23.1% to 32.9% (P < 0.001). The most common cause of liver-related hospitalization in 2000 was hepatocellular carcinoma (HCC) (25.5%); in 2014, gastrointestinal bleeding with esophageal and gastric varices (21.4%) was the most common cause. Cases of hospitalization with liver-related complication represented 76.4% of all cases in 2000 but 70.9% in 2014. Incidence rate of HCC has recently increased. In addition, HCC-free survival was significantly lower in CTP class A than in classes B and C. Finally, there was significant difference in HCC occurrence according to causes (P < 0.001). HBV and HCV cirrhosis had lower HCC-free survival than alcoholic and NAFLD cirrhosis. CONCLUSION In recent years, the overall number of cirrhosis patients has decreased. This study confirmed the recent trend in decrease of cirrhosis, especially of cirrhosis due to HBV, and the increase of HCV, alcoholic and NAFLD cirrhosis. Targeted screening for at-risk patients will facilitate early detection of liver diseases allowing effective intervention and may have decreased the development of cirrhosis and its complications.

Abstract
Background: Given a hepatitis C virus (HCV) elimination goal by 2030, World Health Organization (WHO) guidelines recommend scaling up HCV screening and treatment with highly-effective direct-acting antivirals (DAAs). This study investigated the cost-effectiveness of various screening and treatment strategies for chronic HCV patients in South Korea in patients aged over 40 as compared to currently screening only high-risk patients.Methods: A published Markov disease progression model was used with a screening/treatment decision-tree to model different screening and treatment strategies for Korean HCV patients (aged over 40) from a national payer perspective over a lifetime time horizon. The screening strategies included "screen-all" (upfront only: "once"; or upfront and age 65: "twice") or a "high-risk only" screening strategy followed by treatment. Treatment strategies included either ledipasvir/sofosbuvir (LDV/SOF), SOF + ribavirin (SOF + RBV; in GT2 only), or glecaprevir/pibrentasvir (GLE/PIB). Model inputs were sourced from published literature and costing databases and validated by Korean hepatologists.Results: Regardless of treatment strategy, a "screen all twice" scenario led to the lowest rates of advanced liver disease events compared to "screen all once" and "high-risk only" screening scenarios. In this screening scenario, treatment with LDV/SOF for GT1/2 dominates (i.e. is more effective and less4costly) LDV/SOF in GT1 and SOF + RBV in GT2, while GLE/PIB is not cost-effective relative to LDV/SOF (₩105,124,920/QALY) at a willingness-to-pay threshold of 1xGDP per capita.Conclusion: Screening all South Korean patients twice followed by LDV/SOF treatment is cost-effective as compared current high-risk screening. Adopting this strategy can help achieve WHO HCV elimination goals.

Abstract
BACKGROUND AND AIMS Hepatitis C virus (HCV) and its sequelae present a significant source of economic and societal burden. Introduction of highly effective curative therapies has made HCV elimination attainable. The study used a predictive model to assess the clinical and economic impact of implementing national screening and treatment policies toward HCV elimination in Korea. METHODS A previously validated Markov disease progression model of HCV infection was employed to analyze the clinical and economic impact of various strategies for HCV diagnosis and treatment in Korea. In this analysis, the model compared the clinical and economic outcomes of current HCV-related interventions in Korea (7,000 patients treated and 4,200 patients newly diagnosed annually, starting in 2017) to four elimination scenarios: 1) initiating sufficient diagnosis and treatment interventions to meet the World Health Organization's GHSS elimination targets by 2030, 2) delaying initiation of interventions by one year, 3) delaying initiation of interventions by two years and 4) accelerating initiation of interventions to meet elimination targets by 2025. Modelled historical incidence of HCV was calibrated to match a viremic HCV prevalence of 0.44% in 2009. Elimination scenarios required 24,000 treatments and 34,000 newly diagnosed patients annually, starting in 2018, to reach the 2030 targets. RESULTS Compared to current "status quo" interventions, elimination (or accelerated elimination by 2025) would avert 23,700 (27,000) incident cases of HCV, 1,300 (1,400) liver-related deaths (LRDs) and 2,900 (3,100) cases of end-stage liver disease (ESLD) over the 2017-2030 time period. Postponing interventions by one (or two) years would avert 21,100 (18,600) new HCV infections, 920 (660) LRDs and 2,000 (1,400) cases of ESLD by 2030. Following elimination or accelerated elimination strategies would save 860 million USD or 1.1 billion USD by 2030, respectively, compared to the status quo, requiring an up-front investment in prevention that decreases spending on liver-related complications and death. CONCLUSIONS By projecting the impact of interventions and tracking progress toward GHSS elimination targets using modelling, we demonstrate that Korea can prevent significant morbidity, mortality and spending on HCV. Results should serve as the backbone for policy and decision-making, demonstrating how aggressive prevention measures are designed to reduce future costs and increase the health of the public.

Abstract
The Asia-Pacific region is home to more than half of the global population and accounted for 62·6% of global deaths due to liver diseases in 2015. 54·3% of global deaths due to cirrhosis, 72·7% of global deaths due to hepatocellular carcinoma, and more than two-thirds of the global burden of acute viral hepatitis occurred in this region in 2015. Chronic hepatitis B virus (HBV) infection caused more than half of the deaths due to cirrhosis in the region, followed by alcohol consumption (20·8%), non-alcoholic fatty liver disease (NAFLD; 12·1%), and chronic infection with hepatitis C virus (HCV; 15·7%). In 2015, HBV accounted for about half the cases of hepatocellular carcinoma in the region. Preventive strategies for viral hepatitis-related liver disease include increasing access to clean drinking water and sanitation. HBV vaccination programmes for neonates have been implemented by all countries, although birth-dose coverage is extremely suboptimal in some. Availability of screening tests for blood and tissue, donor recall policies, and harm reduction strategies are in their initial stages in most countries. Many governments have put HBV and HCV drugs on their essential medicines lists and the availability of generic versions of these drugs has reduced costs. Efforts to eliminate viral hepatitis as a public health threat, together with the rapid increase in per-capita alcohol consumption in countries and the epidemic of obesity, are expected to change the spectrum of liver diseases in the Asia-Pacific region in the near future. The increasing burden of alcohol-related liver diseases can be contained through government policies to limit consumption and promote less harmful patterns of alcohol use, which are in place in some countries but need to be enforced more strictly. Steps are needed to control obesity and NAFLD, including policies to promote healthy lifestyles and regulate the food industry. Inadequate infrastructure and insufficient health-care personnel trained in liver diseases are issues that also need to be addressed in the Asia-Pacific region. The policy response of most governments to liver diseases has thus far been inadequate and poorly funded. There must be a renewed focus on prevention, early detection, timely referral, and research into the best means to introduce and improve health interventions to reduce the burden of liver diseases in the Asia-Pacific region.

Abstract
The treatment of inflammatory bowel disease (IBD) has been revolutionized for the last 10 years by the increasing use of immunomodulators and biologics. With immunosuppression of this kind, opportunistic infection is an important safety concern for patients with IBD. In particular, viral hepatitis is determined by the interaction between the virus and the host's immunity, and the risk of reactivation increases if immunity is compromised by immunosuppression therapy. Parts of Asia, including Korea, still show intermediate endemicity for the hepatitis A virus and hepatitis B virus compared with the United States and Western Europe. Thus, members of IBD research group of the Korean Association for the Study of Intestinal Diseases have produced a guideline on the prevention and management of viral hepatitis in IBD.

Abstract
Background: Data about the association between hepatitis virus infection and colorectal neoplasia (CRN) are extremely limited. We examined the association between hepatitis B virus (HBV) and hepatitis C virus (HCV) infection with the risk of CRN. Methods: A cross-sectional study was performed on asymptomatic examinees who underwent a colonoscopy and serologic testing for hepatitis B surface antigen (HBsAg) and hepatitis C antibody (HCV Ab) between 2004 and 2015. Results: Of 155,674 participants who underwent serologic testing for HBsAg, 5476 (3.5%) were positive for HBsAg. The mean age of the study participants was 41.1 ± 9.1 years. The prevalence of CRN was higher in the HBsAg (+) than in HBsAg (-) participants (16.9% vs. 15.6%, p = 0.009). Even after adjusting for confounders, HBsAg positivity was correlated with an increased risk of CRN (odds ratio (OR), 1.10; 95% confidence interval (CI), 1.01–1.19; p = 0.025). Of 155,180 participants who underwent serologic testing for HCV Ab, only 240 (0.15%) were positive for HCV Ab. The prevalence of CRN was higher in HCV Ab (+) than in HCV Ab (-) participants (22.9% vs. 15.6%, p = 0.002). However, the association disappeared after adjusting for confounders (OR, 1.04; 95% CI, 0.72–1.50; p = 0.839). Conclusions: HBV infection was independently correlated with an increased risk of CRN. Our results indicate the possibility that HBV infection may contribute to colorectal carcinogenesis. Screening colonoscopy may have to be recommended more thoroughly for HBV-infected patients.

Trends in the prevalence of chronic liver disease in the Korean adult population, 1998-2017. Clin Mol Hepatol 2019; 26:209-215. [PMID: 31679316 PMCID: PMC7160351 DOI: 10.3350/cmh.2019.0065] [Citation(s) in RCA: 74] [Impact Index Per Article: 14.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Accepted: 09/02/2019] [Indexed: 01/11/2023] Open
Abstract
Data on the trends in the prevalence of chronic liver disease (CLD) in Korea are scarce. This study aimed to evaluate whether the CLD prevalence changed between 1998-2001 and 2016-2017. Data were extracted from the Korea National Health and Nutrition Examination Survey (1998-2001 to 2016-2017; n=25,893). Non-alcoholic fatty liver disease (NAFLD) was defined as a hepatic steatosis index >36 in the absence of any other evidence of CLD. The definition of alcoholrelated liver disease (ALD) was excessive alcohol consumption (≥210 g/week for men and ≥140 g/week for women) and an ALD/NAFLD index >0. The prevalence of NAFLD increased from 18.6% (95% confidence interval [CI], 17.8-19.5%) in 1998-2001 to 21.5% (95% CI, 20.6-22.6%) in 2016-2017. During the same time period, increases were observed in the prevalence of obesity (27.0 vs. 35.1%), central obesity (29.4 vs. 36.0%), diabetes (7.5 vs. 10.6%), and excessive drinking (7.3 vs. 10.5%). ALD prevalence also increased from 3.8% (95% CI, 3.4-4.2%) to 7.0% (95% CI, 6.4-7.6%). In contrast, chronic hepatitis B decreased from 5.1% (95% CI, 4.6-5.5%) to 3.4% (95% CI, 3.0-3.8%). The prevalence of chronic hepatitis C was approximately 0.3% in 2016-2017. The prevalence of NAFLD and ALD increase among Korean adults. Our results suggest potential targets for interventions to reduce the future burden of CLD.

Abstract
This study aimed to investigate the real-life effectiveness and safety of daclatasvir (DCV) and asunaprevir (ASV) combination therapy in Korean patients. We consecutively enrolled patients with genotype 1b hepatitis C virus (HCV) infection treated with at least one dose of DCV/ASV combination therapy in seven tertiary hospitals of South Korea. The sustained virologic response (SVR) rates and safety according to intention-to-treat (ITT) and per-protocol (PP) analyses were evaluated. Among the 526 enrolled patients, 91% showed negative (87%) or "undetermined" (4%) resistance-associated substitution (RAS); 9% did not undergo RAS testing. The SVR rates for ITT and PP were 89.3% and 95.0% in treatment-naive patients and 93.2% and 95.6% in treatment-experienced patients, respectively. In PP analysis, negative RAS was associated with higher SVR (96.3%) than with "undetermined RAS" (85.7%) or "not tested for RAS" (84.4%). Adverse events were reported in 185 (35.4%) patients, and events leading to discontinuation were observed in 4.3% of the study population. Forty-two (8.0%) patients developed transaminase elevation (≥2 × upper normal limit), resulting in treatment discontinuation in six (1.1%) patients. DCV/ASV combination therapy showed acceptable efficacy in genotype 1b compensated HCV-infected patients with negative pretreatment RAS. Although most adverse events were tolerable to continue antiviral treatment, adequate monitoring for transaminase elevation is warranted.

The change in the nationwide seroprevalence of hepatitis C virus and the status of linkage to care in South Korea from 2009 to 2015. Hepatol Int 2019; 13:599-608. [PMID: 31432446 DOI: 10.1007/s12072-019-09975-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Accepted: 07/29/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Hepatitis C virus (HCV) requires epidemiological monitoring to estimate its disease burden and to develop countermeasures. This study aimed to investigate the difference between the 2015 and 2009 nationwide anti-HCV seroprevalence and to determine linkage to care estimates in South Korea. METHODS A total 268,422 examinees ≥ 20 years old were included in 2015 from 33 medical institutions nationwide. Electronically extracted data were retrospectively analyzed to calculate the age-, sex-, and area-adjusted anti-HCV prevalence. Seroprevalence in 2015 was measured using the same method as that in 2009. For anti-HCV-positive subjects, medical records were reviewed to see whether HCV RNA testing or antiviral treatment was performed. RESULTS Adjusted anti-HCV prevalence was 0.60% (95% confidence interval, 0.57-0.63) based on general Korean population in 2015. It showed an increasing trend according to age; 0.23% in thirties, 0.38% in forties, 0.63% in fifties, 1.08% in sixties, and 1.65% in those aged ≥ 70 years. From 2009 to 2015, the adjusted anti-HCV prevalence decreased by 30%, with odds ratio of 0.70 (95% CI 0.70-0.71). There was significant intranational regional variation and changing pattern of seroprevalence. Among 1359 anti-HCV-positive subjects, HCV RNA test was performed in 60% and 25.4% had positivity. Treatment-initiated and cured rates in 2015 were 18.5% and 10.9%, respectively. CONCLUSIONS Anti-HCV prevalence in South Korea was 0.6% in 2015, showing a 30% decrease from that in 2009. Although the HCV RNA testing rate was increased since 2009, this remains suboptimal. Moreover, the treatment uptake rate should be improved in South Korea.

Abstract
BACKGROUND/AIMS In the Republic of Korea, an estimated 231,000 individuals have chronic hepatitis C virus (HCV) infection. The aim of the present analysis was to evaluate the safety and efficacy of elbasvir/grazoprevir (EBR/GZR) administered for 12 weeks in Korean patients who were enrolled in international clinical trial phase 3 studies. METHODS This was a retrospective, integrated analysis of data from patients with HCV genotype (GT) 1b infection enrolled at Korean study sites in four EBR/GZR phase 3 clinical trials. Patients were treatment-naive or had previously failed interferon-based HCV therapy, and included those with human immunodeficiency virus coinfection or ChildPugh class A cirrhosis. All patients received EBR 50 mg/GZR 100 mg once daily for 12 weeks. The primary endpoint was sustained virologic response at 12 weeks after completion of therapy (SVR12, HCV RNA <15 IU/mL). RESULTS SVR12 was achieved by 73 of 74 (98.6%) patients. No patients had virologic failure and one discontinued from the study after withdrawing consent. SVR12 rates were uniformly high across all patient subgroups. A total of 16 patients had nonstructural protein 5A resistance-associated substitutions at baseline (16/73, 22%), all of whom achieved SVR12. Adverse events (AEs) reported in >5% of patients were fatigue (6.8%), upper respiratory tract infection (5.4%), headache (5.4%), and nausea (5.4%). Thirteen patients (17.6%) reported drug-related AEs, two serious AEs occurred, and two patients discontinued treatment owing to an AEs. CONCLUSION In this retrospective analysis, EBR/GZR administered for 12 weeks was well-tolerated and highly effective in Korean patients with HCV GT1b infection.

Abstract
Background Hepatitis C virus (HCV) infection is one of the leading causes of liver cancer, creating enormous economic and social burdens. The Chinese government recommends routine screening of inpatients for HCV before invasive procedures to prevent iatric infections. However, the diagnosis and treatment rates for HCV remain low. The aim of this study was to use available routine screening data to understand the HCV screening of inpatients in different regions of China. Methods Inpatient information and HCV screening results were collected from January 2016 to December 2016 at eight tertiary hospitals in different regions of China to compare the HCV-positivity of hospitalized patients among different regions and age groups. Results The HCV screening rate of inpatients was more than 50%. A total of 467,008 inpatients were enrolled in the study (51.20% were male), and the HCV antibody (anti-HCV) -positive rate was 0.88% (95% confidence interval [CI], 0.85–0.91%) among the total population. This rate was significantly higher among all males compared with all females (0.91% vs 0.85%). Moreover, the HCV antibody-positive rate increased with age and was highest for the 60–64-year age group. Notably, 90.14% (3722/4129) of the anti-HCV seropositive patients were 40 years of age or older. HCV screening for people over 40 years old is recommended. Conclusions This study highlights the key role of routine examination for HCV infection in hospitalized patients. Full use of inpatient screening results to manage HCV antibody-positive patients and a screening strategy targeting inpatients 40 years and older were found to be low-cost and effective, which will help to find the missing millions of yet unaware patients and also accelerate the elimination of HCV in China.

Abstract
BACKGROUND AND AIM For genotype 2 chronic hepatitis C (CHC), the efficacy and safety of sofosbuvir plus ribavirin therapy (SOF + RBV) was better than pegylated interferon plus ribavirin therapy (PR) at a greater drug cost. This study investigated the cost-effectiveness of SOF + RBV compared with PR for treatment-naïve genotype 2 CHC in South Korea. METHODS Using a decision analytic Markov model, a cost-effectiveness analysis comparing SOF + RBV with PR or no treatment for treatment-naïve genotype 2 CHC was performed with probabilistic and deterministic sensitivity analyses from the payer's perspective in 2017. Three cohorts of patients aged 40-49, 50-59, and 60-69 years were simulated to progress through the fibrosis stages F0-F4 to end-stage liver disease, hepatocellular carcinoma, or death. Published and calculated data on the clinical efficacy of the regimen, health-related quality of life, costs, and transition probabilities were used. RESULTS While the incremental cost-effectiveness ratio for PR was dominant over no treatment, the incremental cost-effectiveness ratios for SOF + RBV were $20 058 for the patients in their 40s, $19 662 for those in their 50s, and $22 278 for those in their 60s compared with PR. Probabilistic sensitivity analysis indicated an 89.0% probability for the SOF + RBV to be cost-effective at a willingness to pay of $29 754.4 (per-capita gross domestic product in 2017) for the patients in their 40s and 94.1% and 89.1% for the patients in their 50s and 60s, respectively. CONCLUSIONS The SOF + RBV is a cost-effective option for genotype 2 treatment-naïve CHC patients, especially for the patients with liver cirrhosis in Korea.

Abstract
Background and Aims: Recently, the World Health Organization adopted the first-ever global hepatitis strategy with the dream of eliminating viral hepatitis as a public health threat by 2030. However, the epidemiology and treatment rates of hepatitis C virus (HCV) infection in Western China are still unknown. Methods: A total of 111,916 adult individuals (15-96 years) who underwent the HCV-antibody (HCV-Ab) test in the Second Affiliated Hospital of Chongqing Medical University between 2013 and 2015 were included in this study. We retrospectively analyzed the electronic medical records' data for each, and the positivity of HCV-Ab and the treatment of HCV RNA-positive patients were evaluated. Results: During 2013-2015, the crude prevalence of HCV-Ab was 1.4% (95%CI: 1.4-1.5; 1,611/111,916) and the adjusted prevalence of HCV-Ab was 1.7% (95%CI: 1.6-1.8), which was higher than in the 2006 national study (0.43%). The prevalence was 2-times higher in males than females (2.0% vs. 1.1%, p < 0.01). Notably, only 46% (434/951) of the HCV RNA-positive patients received standard peg-interferon plus ribavirin treatment, with 370 (82%) that completed treatment, of whom 272 (74%) achieved sustained virologic response (SVR). Particularly, 11% (32/292) of HCV RNA-positive patients were HBsAg-positive, and the SVR rate for them was lower than for the HBsAg-negative patients, but no significant difference was observed. Conclusions: HCV infection may have increased since 2006 in Western China. The SVR rate of peg-interferon plus ribavirin treatment was high, but the proportion of untreated HCV patients was large. Thus, more efforts need to be made by the government to create a scientific-based policy for HCV treatment and prevention.

Abstract
PURPOSE The Korean society has moved rapidly toward becoming a multicultural society. This study aimed to estimate the seroprevalence of hepatitis viruses and investigate hepatitis B virus (HBV) genotypic diversity in female marriage immigrants. MATERIALS AND METHODS Screening program was conducted at support centers for multicultural families in 21 administrative districts in Korea between July 2011 and January 2017. A total of 963 female marriage immigrants were included in this study. Blood samples were tested for hepatitis viral markers and HBV genotype. RESULTS Subjects' median age was 33 years (20-40 years), and they originated from nine countries including Vietnam (n=422, 43.8%), China (n=311, 32.3%), the Philippines (n=85, 8.8%), Cambodia (n=58, 6.0%), and Japan (n=39, 4.0%). About 30% (n=288) of subjects required hepatitis A vaccination. HBsAg positive rate was 5.4% (n=52). Positive HBsAg results were the highest in subjects from Southeast Asia (6.6%, n=38). Anti-HBs positive rate was 60.4% (n=582). About 34% (n=329) of subjects who were negative for anti-HBs and HBsAg required HBV vaccinations. Genotypes B and C were found in 54.6% (n=12) and 45.4% (n=10) of the 22 subjects with HBV, in whom genotypes were tested. Eight (0.8%) subjects were positive for anti-HCV. Positive anti-HCV results were the highest in subjects from Central Asia (7.9%, n=3). CONCLUSION Testing for hepatitis viral marker (hepatitis A virus IgG and HBsAg/anti-HBs) is needed for female marriage immigrants. Especially, HBV genotype B is different from genotype C of Koreans. Therefore, interest and attention to vaccination programs for female marriage immigrants are necessary for both clinicians and public health institutes.

Efficacy and safety of sofosbuvir plus ribavirin for Korean patients with hepatitis C virus genotype 2 infection: A retrospective multi-institutional study. Clin Mol Hepatol 2018; 24:311-318. [PMID: 29865774 PMCID: PMC6166109 DOI: 10.3350/cmh.2017.0070] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Revised: 01/23/2018] [Accepted: 02/26/2018] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND/AIMS Sofosbuvir plus ribavirin is a standard treatment for patients infected with chronic hepatitis C virus (HCV) genotype 2 in Korea. The purpose of this study was to examine the efficacy and safety of this treatment in Korean patients with chronic HCV genotype 2 infection. METHODS We retrospectively analyzed clinical data of patients treated with sofosbuvir plus ribavirin for chronic HCV genotype 2 from May 2016 to December 2017 at eight hospitals located in the Daejeon-Chungcheong area. RESULTS A total of 172 patients were treated with sofosbuvir plus ribavirin. Of them, 163 patients completed the treatment, and 162 patients were tested for sustained virologic response 12 weeks after treatment discontinuation (SVR12). Mean age was 59.6±12.3 years (27-96), and 105 (64.4%) patients were female. Of the total patients, 49 (30.1%) were diagnosed with cirrhosis, and 31 of them were treated for 16 weeks. Sofosbuvir plus ribavirin was the first-line treatment for 144 (88.3%) patients. Eleven (6.7%) patients were intolerant to previous interferon-based treatment. Eight (5.0%) patients relapsed after interferon-based treatment. HCV RNA non-detection rate at 4, 8, and 12 weeks was 97.5%, 99.1%, and 99.3%, respectively, and SVR12 was 98.8% (161/163). During treatment, 18 (11.0%) patients had to reduce their administrated dose of ribavirin because of anemia. One patient stopped the treatment because of severe anemia. Other adverse events, including dizziness, indigestion, and headache, were found in 26 (16.0%) patients. CONCLUSION A 12-16 week treatment with sofosbuvir plus ribavirin is remarkably effective and well tolerated in Korean patients with chronic HCV genotype 2 infection.

Abstract
Background/Aims The introduction of direct-acting antivirals (DAA) in 2013 revolutionized hepatitis C virus (HCV) treatment, offering a cure rate >90%. However, this therapy is expensive, and estimations of the number of chronic HCV-infected (CHC) patients and their treatment costs pre-2013 are therefore essential for creating policies and expanding drug access. Herein, we aimed to investigate the number of HCV-related liver disease patients, their healthcare utilization, their annual direct medical costs, and the interferon-based antiviral treatment rates and costs from 2009 to 2013 in South Korea. Methods The National Health Insurance database was reviewed, and patients diagnosed with CHC from 2009 to 2013 were extracted. Data regarding detailed healthcare utilization, prescribed drugs, and direct medical costs were obtained. For annual direct healthcare cost calculations, a prevalence-based approach was used. Results Overall, 181,768 CHC patients were identified. In 2013, the annual per-patient costs for chronic hepatitis, liver cirrhosis, hepatocellular carcinoma, and the first year post-liver transplant were 895, 1,873, 6,945, and 67,359 United States dollars, respectively. Interferon-based antiviral therapeutics were prescribed to 25,223 patients (13.9%). Conclusions Healthcare costs have increased remarkably with increasing liver disease severity. Thus, efforts to stop disease progression are needed. Moreover, the low rate of interferon-based therapy indicates an unmet need for DAA.

Abstract
Chronic, untreated hepatitis C virus (HCV) infection is associated with a poor clinical prognosis and a detrimental impact on patients' lives, including on work productivity. To estimate the value of productivity losses due to genotype 1 (GT1) HCV infection in Hong Kong, Singapore, South Korea and Taiwan and to estimate the potential productivity gains associated with treating patients with ledipasvir/sofosbuvir (LDV/SOF) therapy, an economic model was developed with a time horizon of 1 year. Hepatitis C virus patients entered the model at 12 weeks post-treatment, having achieved or not achieved sustained virological response (SVR). Absenteeism and presenteeism rates were taken from a pooled analysis of data from the ION 1-3 studies. These rates were converted into hours of lost productivity, multiplied by the average wage and applied to the total employed, adult GT1 population in each country. Results were compared assuming no treatment, and assuming all patients were treated with LDV/SOF. Total productivity losses due to untreated HCV were: $11.3 million, $17.1 m, $146.0 m and $349.1 m in Hong Kong, Singapore, South Korea and Taiwan. LDV/SOF treatment resulted in economic gains of $4.5 m, $6.8 m, $58.7 m and $138 m, respectively. These gains were due to reduced presenteeism. The results were sensitive to changes in the prevalence of HCV and the average wage. In conclusion, productivity losses due to untreated HCV infection represent a substantial economic burden. By instituting universal HCV treatment with LDV/SOF (or other therapies with high SVR rates), productivity gains can be achieved.

Abstract
Liver cancer is the sixth most common cancer (fourth in men and sixth in women) and the second largest cause of cancer mortality in South Korea. The crude incidence rate of liver cancer was 31.9/100,000 (47.5/100,000 in men and 16.2/100,000 in women) and the age-standardized incidence rate was 19.9/100,000 (32.4/100,000 in men and 8.8/100,000 in women) in 2014. The crude incidence rate increased from 1999 to 2011 and thereafter showed a subtle decreasing tendency. The crude prevalence rate was 113.6/100,000 (170.2/100,000 in men and 57.1/100,000 in women) and the age-standardized prevalence rate was 72.6/100,000 (115.7/100,000 in men and 33.7/100,000 in women) in 2014, which increased from 2010 to 2014. Survival from liver cancer has improved over the last two decades. The 5-year relative survival rate was markedly increased from 10.7% in those diagnosed with liver cancer between 1993 and 1995 to 32.8% in those diagnosed between 2010 and 2014. The epidemiology of liver cancer is influenced by that of underlying liver diseases such as viral hepatitis. Substantial progress has been made in the prevention and treatment of viral hepatitis; however, uncontrolled alcoholic liver disease, obesity and diabetes appears to have the potential to emerge as major causes for liver cancer. Depending on the success of the control of risk factors, the epidemiology of liver cancer in Korea may change.

Abstract
Chronic hepatitis C (CHC) is caused by hepatitis C virus (HCV) infection. HCV infection causes acute hepatitis, and the majority of those infected progress to chronic hepatitis, and some of them develop cirrhosis and hepatocellular carcinoma. Transmission of HCV is parenteral, and the major transmission routes include drug abuse, insecure injections or medical procedures, contaminated syringes or needles, sexual contact with an HCV-infected person, vertical infection of newborns by infected mothers, the transfusion of blood or blood products contaminated with viruses, and organ transplants. As no vaccine against HCV is available, HCV management involves blocking routes of transmission transmission, screening for HCV infection, and protecting liver disease progression by treatment. Highly potent oral direct antiviral agents are now available. Therefore, early detection through nation-wide screening program and appropriate treatment should be implemented to improve the quality of life of patients with HCV. Furthermore, for the effective HCV control in South Korea, The organization of an 'integrated national viral hepatitis control system' is desirable.

Abstract
The role of hepatitis virus infection in glucose homeostasis is uncertain. We examined the associations between hepatitis B virus (HBV) or hepatitis C virus (HCV) infection and the development of diabetes in a cohort (N = 439,708) of asymptomatic participants in health screening examinations. In cross-sectional analyses, the multivariable-adjusted odds ratio for prevalent diabetes comparing hepatitis B surface antigen (HBsAg) (+) to HBsAg (−) participants was 1.17 (95% CI 1.06–1.31; P = 0.003). The corresponding odds ratio comparing hepatitis C antibodies (HCV Ab) (+) to HCV Ab (−) participants was 1.43 (95% CI 1.01–2.02, P = 0.043). In prospective analyses, the multivariable-adjusted hazard ratio for incident diabetes comparing HBsAg (+) to HbsAg (−) participants was 1.23 (95% CI 1.08–1.41; P = 0.007). The number of incident cases of diabetes among HCV Ab (+) participants (10 cases) was too small to reliably estimate the prospective association between HCV infection and diabetes. In this large population at low risk of diabetes, HBV and HCV infections were associated with diabetes prevalence and HBV infection with the risk of incident diabetes. Our studies add evidence suggesting that diabetes is an additional metabolic complication of HBV and HCV infection.

Abstract
Hepatitis C virus (HCV) infection is a major cause of liver cirrhosis, hepatocellular carcinoma, and liver-related mortality. The new antiviral drugs against HCV, direct acting antivirals, result in >90% cure rate. This review aimed to summarize the current prevalence, clinical characteristics, outcomes, and treatment response associated with HCV infection, and countermeasures for optimal HCV control in South Korea. Based on a literature review, the current anti-HCV prevalence in the Korean population is 0.6 to 0.8%, with increasing prevalence according to age. The major HCV genotypes in Korean patients were genotype 1b and genotype 2. Successful antiviral treatment leads to significantly reduced liver related complications and mortality. However, only about one third of the individuals with HCV infection seem to be managed under the current national health insurance system, suggesting a remarkable rate of underdiagnoses and subsequent loss of opportunity to cure. A recent study in South Korea showed that targeted population screening for HCV infection is cost-effective. To prevent recently developed clusters of HCV infection in some clinics, mandatory surveillance rather than sentinel surveillance for HCV infection is required and governmental countermeasures to prevent reuse of syringes or other medical devises, and public education should be maintained. Moreover, one-time screening for a targeted population should be considered and a cost-effectiveness study supporting an optimal screening strategy is warranted.

Abstract
BACKGROUND/AIMS Interferon-based treatment is not appropriate for a large number of patients with chronic hepatitis C for various medical and social reasons. Newly developed directly acting antivirals (DAAs) have been used to treat chronic hepatitis C without severe adverse effects and have achieved a sustained viral response (SVR) rate of 80-90% with short treatment duration. We were interested to determine whether all patients who failed to respond to or were ineligible for interferon-based therapy could be treated with DAAs. METHODS Medical records of patients with positive serum anti-hepatitis C virus (HCV) or HCV RNA between January 2009 and December 2013 were reviewed. Demographic, clinical, and treatment data were collected for analysis. RESULTS A total of 876 patients were positive for both anti-HCV and HCV RNA. Of these, 244 patients were eligible for interferon, although this was associated with relapse in 39 (16%) of patients. In total, 130 patients stopped interferon therapy (67% adverse effects, 28% non-adherent, 4% malignancy, 1% alcohol abuse) and 502 patients were ineligible (66% medical contraindications, 25% non-adherent, 5% socioeconomic problems). Among 671 patients who were ineligible for or failed to respond to interferon therapy, more than 186 (27.7%) could not be treated with DAA due to financial, social, or cancer-related conditions. CONCLUSIONS Newly developed DAAs are a promising treatment for patients with chronic hepatitis C who are ineligible for or failed to respond to interferon-based therapy. Nevertheless, not all chronic hepatitis C patients can be treated with DAAs due to various reasons.

Abstract
BACKGROUND Anti-HCV assays are widely used as a screening tool for HCV infection. However, diagnostic performances and effective signal-to-cut-off ratios (S/COs) for predicting true HCV infections would vary according to the assays used. Thus, we evaluated the diagnostic performances of the new Elecsys Anti-HCV assay. METHODS A total of 41 694 cases tested by the Elecsys Anti-HCV II assay (Roche Diagnostics, Germany) during January 2013 to December 2015 were retrospectively analyzed by comparing with the diagnosis on HCV infections determined by patients' medical records and results of laboratory tests. RESULTS Excluding 62 cases with unclear history of HCV infection, 430 and 41 202 cases were respectively assorted as "true infection" and "no evidence of infection," and 99.85% of the initial results by the Elecsys assay were concordant with the diagnosis on HCV infection. Sensitivity, specificity, positive and negative predictive values were respectively 99.30%, 99.86%, 88.04%, and 99.99%, where the prevalence of the HCV infection was 1.0%. The area under the receiver operating characteristics curve value of the Elecsys assay was 0.9980 (95% confidence interval [CI]=0.9944 to 1.0017). The S/CO by the Elecsys assay for predictive of a true-positive ≥95% of the time was 19.0 (95% CI=15.0 to 25.1). CONCLUSION The Elecsys Anti-HCV II assay showed excellent diagnostic performances, particularly in terms of sensitivity, specificity, and NPV. However, the results obtained by this assay with S/CO less than a certain value would need to be retested by HCV RNA PCR or another anti-HCV assay.

[PMID: 28060834 PMCID: PMC5218507 DOI: 10.1371/journal.pone.0167770] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Accepted: 11/18/2016] [Indexed: 02/06/2023] Open
Abstract
Background and Aims This study aims to investigate the cost-effectiveness of a one-time hepatitis C virus (HCV) screening and treatment program in South Korea where hepatitis B virus (HBV) prevails, in people aged 40–70, compared to current practice (no screening). Methods A published Markov model was used in conjunction with a screening and treatment decision tree to model patient cohorts, aged 40–49, 50–59 and 60–69 years, distributed across chronic hepatitis C (CHC) and compensated cirrhosis (CC) health states (82.5% and 17.5%, respectively). Based on a published seroepidemiology study, HCV prevalence was estimated at 0.60%, 0.80% and 1.53%, respectively. An estimated 71.7% of the population was screened. Post-diagnosis, 39.4% of patients were treated with a newly available all-oral direct-acting antiviral (DAA) regimen over 5 years. Published rates of sustained virologic response, disease management costs, transition rates and utilities were utilised. Results Screening resulted in the identification of 43,635 previously undiagnosed patients across all cohorts. One-time HCV screening and treatment was estimated to be cost-effective across all cohorts; predicted incremental cost-effectiveness ratios ranged from $5,714 to $8,889 per quality-adjusted life year gained. Incremental costs associated with screening, treatment and disease management ranged from $156.47 to $181.85 million USD; lifetime costs-offsets associated with the avoidance of end stage liver disease complications ranged from $51.47 to $57.48 million USD. Conclusions One-time HCV screening and treatment in South Korean people aged 40–70 is likely to be highly cost-effective compared to the current practice of no screening.

Abstract
Background Despite declines in mortality and morbidity rates of patients with human immunodeficiency virus (HIV) infection as the result of highly active antiretroviral therapy, liver diseases due to chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are a leading cause of death among HIV-infected patients. However, HIV and HBV or HCV coinfection is still poorly documented, and more information is needed to better understand the characteristics of HIV-infected patients in Korea. Materials and Methods A cross-sectional study was performed to investigate clinical characteristics and prevalence of HBV and HCV infection in HIV patients enrolled in the Korea HIV/acquired immune deficiency syndrome (AIDS) cohort study from 17 institutions between December 2006 and July 2013. Results Among the 1,218 HIV-infected participants, 541 were included in this study. The prevalence of HBV-HIV and HCV-HIV coinfection was 5.0% (27/541) and 1.7% (9/541), respectively. There was no patient who was positive for both HBs antigen and HCV antibody. In multivariate logistic regression analysis, HBV unvaccinated status was a significant risk factor for HBV-HIV coinfection (odds ratio = 4.95, 95% confidence interval = 1.43–17.13). Conclusions HBV and HCV infection was more common in HIV-infected persons enrolled in the Korean HIV/AIDS cohort, than in the general population in Korea.

Abstract
Background/Aims The prevalence of hepatitis C virus (HCV) infection in Busan, Gyeongnam, and Jeonnam Provinces in Korea is more than twice the national average. This study aimed to examine whether demographic and lifestyle characteristics are associated with HCV infection in these areas. Methods A case control study was performed at three study hospitals. HCV cases were matched with two controls for sex and age. Patient controls were selected from non-HCV patients at the same hospital. Healthy controls were subjects participating in medical checkups. Conditional logistic regression models were used. Results A total of 234 matched-case and patient- and healthy-control pairs were analyzed. The significant risk factors for both controls were sharing razors (adjusted odds ratio [aOR], 2.39 and 3.29, respectively) and having more than four lifetime sexual partners (aOR, 2.15 and 6.89, respectively). Contact dockworkers (aOR, 1.91) and tattoos (aOR, 2.20) were significant risk factors for the patient controls. Transfusion (aOR, 5.38), a bloody operation (aOR, 5.02), acupuncture (aOR, 2.08), and piercing (aOR, 5.95) were significant risk factors for the healthy controls. Needle stick injuries and intravenous drug abuse were significant in the univariate analysis. Conclusions More education concerning the dangers of sharing razors, tattoos and piercings is required to prevent HCV infection. More attention should be paid to needle stick injuries in hospitals and the community.

Abstract
This prospective cohort study aimed to elucidate the clinical outcome and its related factors of chronic hepatitis C in a hepatitis B-dominant Asian region.From January 2007 to October 2012, 382 patients with chronic hepatitis C without liver cirrhosis were prospectively enrolled at 6 university hospitals, and regularly followed until Apr 2014 to identify the development of liver cirrhosis, decompensated cirrhosis, hepatocellular carcinoma (HCC), and overall survival.During the median follow-up of 39.0 months (range 18.0-81.0 months), liver cirrhosis, hepatic decompensation, and HCC developed in 42 patients (11.0%), 4 patients (1.0%), and 12 patients (3.1%), respectively. The cumulative probability of development of cirrhosis at 3 years and at 5 years was 9.6% and 16.7%, respectively. That of HCC at 3 and 5 years was 1.6% and 4.5%, respectively. The 3-year and 5-year overall survival rate was 99.7% and 96.0%, respectively. Pegylated interferon-based antiviral therapy was undertaken in 237 patients (62.0%) with a sustained virologic response (SVR) rate of 74.3%. The factors related to the overall clinical outcomes were age ≥55 years (HR 2.924, P = 0.016), platelet counts <150 × 10/L (HR 3.195, P = 0.007), and the achievement of SVR (HR 0.254, P = 0.002).The clinical outcomes of this Korean chronic hepatitis C cohort were modest with minimal mortality, but significant disease progression occurred in the patients with old age, low platelet, and non-SVR after interferon-based antiviral treatment or no treatment, suggesting priority for direct acting antiviral therapy.

Abstract
The objective of this study was to establish modified cutoff values of serum alpha-fetoprotein (AFP) according to hepatitis status. While AFP is used as a serum marker in the diagnosis or monitoring of hepatocellular carcinoma (HCC), its use as a screening method to the general population is controversial. We evaluated its screening performance in a hepatitis prevalent East Asian population, and suggest different cutoff values according to the individual's hepatitis status. We evaluated the performance of AFP as a screening test in 48,123 consecutive Koreans during the period from March, 2012 to August, 2013 who underwent routine health checks at a single institution. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated with fixed cutoff and with modified cutoffs according the individual's hepatitis status. A total of 24 out of 48,123 subject (0.05%) were newly diagnosed with HCC after screening. Among the 1,874 subject with positive hepatitis B virus surface antigen (HBsAg), 17 (0.91%) developed HCC, compared with two out of 393 (0.51%) individuals with hepatitis C virus antibody (anti-HCV). Five out of 45,855 (0.01%) subject with neither HBsAg nor anti-HCV developed HCC. Compared to the performance of a fixed cutoff, specificity, PPV, and NPV improved without sacrificing sensitivity when applying modified cutoff. In conclusion, our findings suggest that AFP with modified cutoffs according to the individual's hepatitis status might be a useful screening marker for HCC in hepatitis prevalent areas.
