RESUMEN
BACKGROUND/PURPOSE: Chronic kidney disease (CKD) has become a worldwide health problem, leading to high morbidity and mortality, and non-alcoholic fatty liver disease (NAFLD) is considered a risk factor for CKD. The aim of this study was to explore the relationship between NAFLD fibrosis score (NFS) and the estimated glomerular filtration rate (eGFR), and identify possible risk factors related to the NFS among Taiwanese subjects. METHODS: Subjects were enrolled from the database of the Department of Preventive Medicine of Kaohsiung Municipal Hsiao-Kang Hospital. The eGFR was calculated according to the Taiwanese Modification of Diet in Renal Disease (TMDRD) equation, and the NFS was employed to evaluate the fibrotic level. RESULTS: In total, 11,376 subjects were enrolled in this study, with a mean age of 52.0 ± 6.81 years, including 4529 (39.8%) males. A fasting sugar level ≥100 mg/dL (OR = 1.70, 95% CI = 1.52-1.87) and an abnormal waist circumference (OR = 1.81, 95% CI = 1.65-1.99) were significant factors associated with NFS (p < 0.05). Trends of a decreasing TMDRD score and an increasing NFS with increasing age were noted (p < 0.05). The NFS was significantly negatively correlated with the TMDRD score (standard coefficients: -0.067, p < 0.001). CONCLUSION: A higher NFS is associated with an impaired eGFR in Taiwanese subjects. Controlling risk factors, especially fasting sugar level and waist circumference, may be useful in preventing NFS deterioration, which is negatively correlated with the eGFR.

BACKGROUND: The features and risk analysis of non-alcoholic fatty liver disease (NAFLD) in a community-based setting remain elusive. The predictors between obese and lean subjects need further clarification. We aimed to assess the characteristics of NAFLD during a community screening. The associated metabolic abnormalities and cardiovascular risk assessment were also analyzed. METHODS: A total of 2483 subjects receiving multi-purpose health screening at 10 primary care centers were recruited. They received clinical assessment, including demographic data, laboratory examination, and abdominal sonography. RESULTS: The prevalence of NAFLD and metabolic syndrome were 44.5%, and 15.8%, respectively. Among those NAFLD subjects, 1212 (48.8%) subjects were obese (BMI≥ 24 kg/m2). There was an increasing trend of NAFLD according to age, ranging from 25.8% of those aged <30 years to 54.4% of those aged 50-70 years (P for trend< 0.0001). High insulin resistance (IR) was the significant predictive factor for NAFLD in both obese (odds ratio [OR] = 3.85, 95% confidence interval [CI] = 1.87-8.36, P = 0.0002) and lean subjects (OR = 2.52, 95% CI = 1.13-5.54, p = 0.02). The prevalence of high Framingham Risk Score (≥7.5%) was 56.7% (211/372) among the male subjects, which was significantly higher than that (26%, 191/734) of the females (P < 0.001). There was a significant increase of high Framingham Risk Score according to BMI, ranging from 23.1% of BMI<24 kg/m2 to 45% of BMI>27 kg/m2 (P for trend< 0.0001). CONCLUSION: IR is predictive of NAFLD irrespective of BMI. The cardiovascular risk may exist in lean NAFLD subjects.

BACKGROUND & AIMS: Hepatitis C virus (HCV)-infected patients with cirrhosis remain at risk of hepatocellular carcinoma (HCC) even after achieving sustained virological response (SVR). The aim of the study was to explore the incidence and risk for HCC among non-cirrhotic patients with an SVR. METHODS: A total of 642 patients with an SVR after peginterferon/ribavirin therapy were enrolled with a median follow-up period of 53.0 months (range: 6-133 months). RESULTS: Thirty-three of the 642 (5.1%) patients developed HCC over 2324.8 person-years of follow-up. Cox regression analysis revealed that the strongest predictive factor of HCC occurrence was liver cirrhosis (HR 4.98, 95% CI 2.32-10.71, p<0.001), followed by age (HR 1.06, 95% CI 1.02-1.11, p=0.005) and γGT levels (HR 1.008, 95% CI 1.004-1.013, p<0.001). The incidence of HCC did not differ between patients with high and low baseline γGT levels among patients with cirrhosis (p=0.53), but the incidence of HCC was significantly higher in non-cirrhotic patients with high γGT levels compared with those with low γGT levels (p=0.001). Cox regression analysis revealed that the strongest factors associated with HCC development in non-cirrhotic sustained responders were baseline γGT levels (HR 6.44, 95% CI 2.20-18.89, p=0.001) and age (HR 3.68, 95% CI 1.33-10.17, p=0.012). The incidence of HCC was not different between older non-cirrhotic patients with high γGT levels and cirrhotic patients (p=0.34). CONCLUSIONS: HCC remains a threat in non-cirrhotic patients with an SVR. Serum γGT levels helped to identify potential patients at high risk.

BACKGROUND AND AIMS: Fatty liver disease (FLD) is associated with several metabolic derangements. We conducted a retrospective cross-sectional and longitudinal study to evaluate the role of FL severity in the risk of new-onset and co-existing hypertension (HTN) and diabetes mellitus (DM). METHODS: The cross-sectional cohort consisted of 41,888 adults who received health checkups in a tertiary hospital of Taiwan from 1999 to 2013. Of them, 34,865 without HTN and/or DM at baseline and within 1 year after enrollment were included as a longitudinal cohort (mean, 6.45 years for HTN; 6.75 years for DM). FL severity based on the degree of hepatic steatosis was assessed by ultrasound sonography. RESULTS: In cross-sectional cohort, 22,852 (54.6%) subjects had FL (18,203 [43.46%] mild FL and 4,649 [11.10%] moderate/severe FL); 13.5% (n = 5668) had HTN; and 3.4% (n = 1411) had DM. Moderate/severe FL and mild FL had significantly higher risks of existing HTN (adjusted odds ratio/95% confidence interval [CI] 1.59/1.43-1.77 and 1.22/1.13-1.32, respectively). In longitudinal cohort, 3,209 and 822 subjects developed new-onset HTN and DM, respectively (annual incidence, 14.3 and 3.5 per 1000 person-years; 10-year cumulative incidence, 14.35% and 3.89%, respectively). Moderate/severe and mild FL had significantly higher risks of new-onset HTN (adjusted hazard ratio [aHR]/CI 1.54/1.34-1.77 and 1.26/1.16-1.37, respectively) and DM (aHR/CI 5.88/4.44-7.81 and 3.22/2.56-4.07, respectively). Resolved FL during follow-up decreased the risk of HTN and/or DM. CONCLUSIONS: Patients with FL are at high risk of prevalent and incident HTN and/or DM. The risk increases with the severity of FL.

We aimed to investigate the association between air pollution and advanced fibrosis among patients with metabolic associated fatty liver disease (MAFLD) and chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. A total of 1376 participants who were seropositive for HBV surface antigen (HBsAg) or antibodies to HCV (anti-HCV) or had abnormal liver function in a community screening program from 2019 to 2021 were enrolled for the assessment of liver fibrosis using transient elastography. Daily estimates of air pollutants (particulate matter ≤2.5 µm in diameter [PM2.5 ], nitrogen dioxide [NO2 ], ozone [O3 ] and benzene) were aggregated into mean estimates for the previous year based on the date of enrolment. Of the 1376 participants, 767 (52.8%) and 187 (13.6) had MAFLD and advanced fibrosis, respectively. A logistic regression analysis revealed that the factors associated with advanced liver fibrosis were HCV viremia (odds ratio [OR], 3.13; 95% confidence interval [CI], 2.05-4.77; p < 0.001), smoking (OR, 1.79; 95% CI, 1.16-2.74; p = 0.01), age (OR, 1.04; 95% CI, 1.02-1.05; p < 0.001) and PM2.5 (OR, 1.10; 95% CI, 1.05-1.16; p < 0.001). Linear regression analysis revealed that LSM was independently correlated with PM2.5 (ß: 0.134; 95% CI: 0.025, 0.243; p = 0.02). There was a dose-dependent relationship between different fibrotic stages and the PM2.5 level (the PM2.5 level in patients with fibrotic stages 0, 1-2 and 3-4: 27.9, 28.4, and 29.3 µg/m3 , respectively; trend p < 0.001). Exposure to PM2.5 , as well as HBV and HCV infections, is associated with advanced liver fibrosis in patients with MAFLD. There was a dose-dependent correlation between PM2.5 levels and the severity of hepatic fibrosis.

After the mass vaccination project in Taiwan, the prevalence of the hepatitis B virus (HBV) infection for the college-aged population of 18 to 21 years is uncertain. We aimed to investigate the prevalence of hepatitis B markers in different birth cohorts. A total of 38,075 students in universities in Kaohsiung area undergoing entrance examinations between July 2006 to September 2020 were included. Seroprevalence of the hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) status and laboratory data were collected. The seropositive rate of HBsAg was less than 1% for students born after 1991. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were significantly higher, and body mass index (BMI) was significantly lower in HBV carriers compared to those who were not carriers (all p < 0.001). Multivariate logistic regression showed that age, male, higher BMI, and positive HBsAg were risk factors of abnormal ALT value. A decrease in the positive rate of anti-HBs which was significantly higher in the cohort of plasma-derived vaccines than recombinant vaccines was found. We concluded that there were decreasing trends in seropositive rates of HBsAg and anti-HBs for students of the college-aged population in the Kaohsiung area. The status of HBsAg was a predictive factor of abnormal ALT levels. The period effect on anti-HBs seropositivity for DNA recombinant vaccine somehow existed.
RESUMEN
The controlled attenuation parameter (CAP) measurement obtained from FibroScan® is a low-risk method of assessing fatty liver. This study investigated the association between the FibroScan® CAP values and nine anthropometric indicators, including the abdominal volume index (AVI), body fat percentage (BFP), body mass index (BMI), conicity index (CI), ponderal index (PI), relative fat mass (RFM), waist circumference (WC), waist-hip ratio (WHR), and waist-to-height ratio (WHtR), and risk of non-alcoholic fatty liver disease (fatty liver). We analyzed the medical records of adult patients who had FibroScan® CAP results. CAP values <238 dB/m were coded as 0 (non- fatty liver) and ≥238 dB/m as 1 (fatty liver). An individual is considered to have class 1 obesity when their body mass index (BMI) ranges from 30 kg/m2 to 34.9 kg/m2. Class 2 obesity is defined by a BMI ranging from 35 kg/m2 to 39.9 kg/m2, while class 3 obesity is designated by a BMI of 40 kg/m2 or higher. Out of 1763 subjects, 908 (51.5%) had fatty liver. The BMI, WHtR, and PI were found to be more strongly correlated with the CAP by the cluster dendrogram with correlation coefficients of 0.58, 0.54, and 0.54, respectively (all p < 0.0001). We found that 28.3% of the individuals without obesity had fatty liver, and 28.2% of the individuals with obesity did not have fatty liver. The BMI, CI, and PI were significant predictors of fatty liver. The BMI, PI, and WHtR demonstrated better predictive ability, indicated by AUC values of 0.72, 0.68, and 0.68, respectively, a finding that was echoed in our cluster group analysis that showed interconnected clustering with the CAP. Therefore, of the nine anthropometric indicators we studied, the BMI, CI, PI, and WHtR were found to be more effective in predicting the CAP score, i.e., fatty liver.
RESUMEN
Background and Aims: Disease severity across the different diagnostic categories of metabolic dysfunction-associated fatty liver disease (MAFLD) remains elusive. This study assessed the fibrosis stages and features of MAFLD between different items. We also aimed to investigate the associations between advanced fibrosis and risk factors. Methods: This multicenter cross-sectional study enrolled adults participating in liver disease screening in the community. Patients were stratified following MAFLD diagnostic criteria, to group A (395 patients) for type 2 diabetes, group B (1,818 patients) for body mass index (BMI)>23 kg/m2, and group C (44 patients) for BMI≤23 kg/m2 with at least two metabolic factors. Advanced fibrosis was defined as a fibrosis-4 index>2.67. Results: Between 2009 and 2020, 1,948 MAFLD patients were recruited, including 478 with concomitant liver diseases. Advanced fibrosis was observed in 125 patients. A significantly larger proportion of patients in group C (25.0%) than in group A (7.6%) and group B (5.8%) had advanced fibrosis (p<0.01). Logistic regression analysis found that hepatitis B virus (HBV)/hepatitis C virus (HCV) coinfection (odds ratio [OR]: 12.14, 95% confidence interval [CI]: 4.04-36.52; p<0.01), HCV infection (OR: 7.87, 95% CI: 4.78-12.97; p<0.01), group C (OR: 6.00, 95% CI: 2.53-14.22; p<0.01), and TC/LDL-C (OR: 1.21, 95% CI: 1.06-1.38; p<0.01) were significant predictors of advanced fibrosis. Conclusions: A higher proportion of lean MAFLD patients with metabolic abnormalities had advanced fibrosis. HCV infection was significantly associated with advanced fibrosis.
RESUMEN
OBJECTIVES: Gaps in linkage-to-care remain the barriers toward hepatitis C virus (HCV) elimination in the directly-acting-antivirals (DAA) era, especially during SARS Co-V2 pandemics. We established an outreach project to target HCV micro-elimination in HCV-hyperendemic villages. METHODS: The COMPACT provided "door-by-door" screening by an "outreach HCV-checkpoint team" and an "outreach HCV-care team" for HCV diagnosis, assessment and DAA therapy in Chidong/Chikan villages between 2019 and 2021. Participants from neighboring villages served as Control group. RESULTS: A total of 5731 adult residents participated in the project. Anti-HCV prevalence rate was 24.0% (886/3684) in Target Group and 9.5% (194/2047) in Control group (P < 0.001). The HCV-viremic rates among anti-HCV-positive subjects were 42.7% and 41.2%, respectively, in Target and Control groups. After COMPACT engagement, 80.4% (304/378) HCV-viremic subjects in the Target group were successfully linked-to-care, and Control group (70% (56/80), P = 0.039). The rates of link-to-treatment and SVR12 were comparable between Target (100% and 97.4%, respectively) and Control (100% and 96.4%) groups. The community effectiveness was 76.4% in the COMPACT campaign, significantly higher in Target group than in Control group (78.3% versus 67.5%, P = 0.039). The community effectiveness decreased significantly during SARS Co-V2 pandemic in Control group (from 81% to 31.8%, P < 0.001), but not in Target group (80.3% vs. 71.6%, P = 0.104). CONCLUSIONS: The outreach door-by-door screen strategy with decentralized onsite treatment programs greatly improved HCV care cascade in HCV-hyperendemic areas, a model for HCV elimination in high-risk marginalized communities in SARS Co-V2 pandemic.

BACKGROUND & AIMS: A substantial proportion of hepatitis C virus genotype 1 (HCV-1) patients achieved a sustained virological response (SVR, HCV RNA seronegative throughout 24 weeks of post-treatment follow-up) after 24 weeks peginterferon/ribavirin therapy. We explored the role of interleukin-28B genotype in identifying patients who responded to the regimen. METHODS: Interleukin-28B rs8099917 genotype was determined in 226 HCV-1 patients with 24 weeks peginterferon/ribavirin. RESULTS: Compared to patients with rs8099917 TG/GG genotype, those with TT genotype had significantly higher rapid virological response (RVR, HCV RNA seronegative at treatment week 4, 54.0% vs. 17.9%, p<0.001) and SVR (64.7% vs. 25.6%, p<0.001) rates, and lower relapse rate (28.0% vs. 54.5%, p=0.01). Logistic regression analysis revealed that the strongest factor predictive of a RVR was the carriage of rs8099917 TT genotype (odds ratio/ 95% confidence intervals [OR/CI]: 6.24/2.34-16.63), followed by lower viral loads (OR/CI: 5.29/2.81-9.93) and age (OR/CI:0.94/0.91-9.97). The most important factor predictive of an SVR was the attainment of a RVR (OR/CI: 22.23/9.22-53.58), followed by the carriage of rs8099917 TT genotype (OR/CI: 3.38/1.18-9.65), lower viral loads (OR/CI: 2.23/1.00-4.93) and ribavirin exposure dose (OR/CI: 1.17/1.06-1.30). The determinant power of rs8099917 genotype on SVR was mainly restricted to non-RVR patients, particularly those with higher baseline viral loads. Combination of the two pretreatment predictors, interleukin-28B genotype and baseline viral loads, could predict treatment efficacy with a positive predictive value of 80% and a negative predictive value of 91%. CONCLUSIONS: Interleukin-28B genotype could help identifying patients who are or are not candidates for an abbreviated regimen before treatment.

UNLABELLED: Genome-wide association studies have linked single nucleotide polymorphisms (SNPs) near the interleukin-28B gene to the hepatitis C virus genotype 1 (HCV-1) response to peginterferon/ribavirin treatment. We aimed to explore the impact on the treatment outcomes of Asian HCV-2 patients. We determined rs8105790, rs8099917, rs4803219, and rs10853728 to be candidate SNPs in 482 Asian HCV-2 patients treated with the standard of care. Because the first three SNPs were in very strong linkage disequilibrium with one another (r2 = 0.94-0.96), rs8099917 and rs10853728 were selected for an analysis of their influence on the achievement of rapid virological response [RVR; seronegativity for hepatitis C virus (HCV) RNA in treatment week 4] and sustained virological response (SVR; seronegativity for HCV RNA throughout 24 weeks of posttreatment follow-up). The rs10853728 genotype did not predict RVR or SVR in HCV-2 patients. However, patients with the rs8099917 TT genotype, in comparison with patients with GT/GG genotypes, had a significantly higher rate of achieving RVR (85.2% versus 72.0%, P = 0.017) but did have not a significantly higher rate of achieving SVR (89.4% versus 86.0%). Multivariate analysis revealed that a baseline HCV viral load <400,000 IU/mL was the strongest predictor of RVR [odds ratio (OR) = 4.27, 95% confidence interval (CI) = 2.31-7.87, P < 0.001], and this was followed by advanced liver fibrosis (OR = 0.28, 95% CI = 0.15-0.53, P < 0.001), the carriage of the rs8099917 TT genotype (OR = 3.10, 95% CI = 1.34-7.21, P = 0.008), and the pretreatment level of aspartate aminotransferase (OR = 0.996, 95% CI = 0.99-1.00, P = 0.04). Nevertheless, the achievement of RVR was the single predictor of SVR with an OR of 19.37 (95% CI = 8.89-42.23, P < 0.001), whereas the rs8099917 genotypes played no role in achieving SVR with or without RVR. CONCLUSION: The rs8099917 TT genotype is significantly independently predictive of RVR, which is the single best predictor of SVR, in Asian HCV-2 patients.

BACKGROUND/AIMS: Pre-diabetes is a risk factor for type 2 diabetes mellitus (DM) development. This study aimed to elucidate the impact of treatment response on sequential changes in glucose abnormalities in pre-diabetic chronic hepatitis C (CHC) patients. METHODS: Chronic Hepatitis C patients with a baseline haemoglobin A1C (A1C) range 5.7-6.4% who achieved 80/80/80 adherence were prospectively recruited. All patients received current peginterferon-based recommendations. The primary outcome measurement was their A1C level at the end of follow-up (EOF). The interaction between variants of the IL28B gene and outcomes of glucose metabolism was also measured. RESULTS: A total of 181 consecutive CHC patients were enrolled. The mean A1C at EOF was 5.82 ± 0.41%, which was significantly lower than the baseline level (5.93 ± 0.21%, P < 0.001). At EOF, 63 (34.8%) patients became normoglycaemic, whereas 10 (5.5%) patients developed DM. The sustained virological response (SVR) rates of 63 normoglycaemics, 108 pre-diabetics and 10 diabetic patients at the EOF were 92.1%, 84.3% and 50% respectively (normoglycaemics vs. diabetics P = 0.003; pre-diabetics vs. diabetics P = 0.02). Achievement of an SVR was the only predictive factor associated with normoglycaemia development at EOF by multivariate logistic regression analysis (Odds ratio = 2.6, P = 0.04). The prevalence of the interleukin 28B rs8099917 TT variant in patients who developed DM (70.0%) at EOF tended to be lower than that in patients with pre-diabetics (87.0%) or normoglycaemics (92.1%). CONCLUSION: Successful eradication of HCV improves glucose abnormalities in pre-diabetic CHC patients.

Understanding the barriers and tackling the hurdles of hepatitis C virus (HCV) care cascades is key to HCV elimination. The current study aimed to investigate the rates of disease awareness, link-to-care, and treatment uptake of HCV in a hyperendemic area in Taiwan. Tzukuan residents from 2000 to 2018 were invited to participate in the questionnaire-based interviews for HCV. The rates of disease awareness, accessibility, and anti-HCV therapy were evaluated in anti-HCV-seropositive participants. Among 10,348 residents, 1789 (17.3%) were anti-HCV seropositive. Of these 1789 anti-HCV-seropositive participants, data of 594 participants from questionnaire-based interviews in 2005-2018 were analyzed for HCV care cascades. Overall, 24.9% of anti-HCV-seropositive HCV participants had disease awareness, 53.9% of aware participants had accessibility, and 79.8% of assessed participants had received HCV treatment, with a community effectiveness of 10.7%. HCV prevalence decreased over time, from 21.2% in the early cohort to 9.3% in the recent cohort. Disease awareness increased over time, from 15.6% to 41.7%, with the community effectiveness increasing from 1.3% to 28.8%. Lower education levels and normal liver biochemistry were associated with a lower rate of disease awareness. Notably, 68% of participants with abnormal liver biochemistry and 69% of those with advanced fibrosis (FIB-4 > 3.25) were unaware of their HCV disease. We demonstrated huge gaps in disease awareness, link-to-care, and treatment uptake in the HCV care cascade in an HCV-hyperendemic area, even in the initial era of direct-acting antiviral agents. There is an urgent need to overcome these hurdles to achieve HCV elimination.

Hepatitis C virus (HCV) eradication through antivirals ameliorates metabolic profiles. The changes in 2-h plasma glucose (2HPG) levels by oral glucose tolerance test (OGTT), in chronic hepatitis C (CHC) patients who receive directly acting antivirals (DAAs) was elusive. Five hundred and thirty-three CHC patients who achieved sustained virological response (SVR, undetectable HCV RNA throughout 3 months after the end-of-treatment) by DAAs were consecutively enrolled. Pre- and posttreatment 2HPG levels and glucose status were compared. The proportion of patients with improved, worsened, and stable 2HPG was 14.4% (n = 77), 18.6% (n = 99), and 67.0% (n = 357), respectively. Compared with patients with worsening 2HPG, those with improved 2HPG had a higher proportion of cirrhosis (45.5% vs. 24.2%, p = 0.004) and higher pretreatment 2HPG levels (175.3 vs. 129.5 mg/dl, p < 0.001). High baseline 2HPG was independently associated with improved 2HPG in multivariate analysis (odds ratio [OR]/CI: 1.05/1.03-1.06, p < 0.001). When baseline 2HPG was not taken into account, cirrhosis was the only factor independently associated with improved 2HPG status (OR/CI: 2.58/1.29-5.15, p = 0.007). Linear regression analysis revealed that factors independently correlated to changes in 2HPG levels were female sex (ß: 8.78; 95% CI:2.34, 15.22; p = 0.01), diabetes (ß: -27.72; 95% CI: -50.16, -5.28; p = 0.02), liver cirrhosis (ß: -8.91; 95% CI: -16.75, -2.20; p = 0.01), and genotype 1 of HCV (ß: -0.12; 95% CI: -15.19, -2.43; p = 0.01). 2HPG improved after HCV eradication by DAAs, particularly in cirrhotic patients.

BACKGROUND & AIMS: Evidence on the efficacy of antiviral treatment in chronic hepatitis C (CHC) patients with hepatocellular carcinoma (HCC) after curative treatment is scarce. We aimed to evaluate the efficacy and safety of pegylated interferon-alpha plus ribavirin (pegIFN/RBV) combination therapy in these patients, compared to cirrhotic patients. METHODS: This prospective, multicenter, case-control study recruited 82 consecutive CHC patients with HCC after curative management and 87 sex/age-matched cirrhotic patients. All patients received pegIFN-alpha-2a and weight-based RBV according to current treatment recommendations. The primary outcome measurement was sustained virological response (SVR, seronegative of hepatitis C virus RNA throughout the 6-month post-treatment follow-up period). RESULTS: The SVR rate was significantly lower in the HCC group compared to the cirrhosis group (48.8% vs 64.4%, p=0.04). However, the significantly lower rate of SVR in the HCC group was observed among genotype-1 patients (33.3% vs 60.7%, p=0.005) but not among genotype-2/3 patients (70.6% vs 71.0%, p=0.88). In patients who achieved 80/80/80 adherence, there was no significant difference of SVR rate between groups (50.7% vs 64.2%, p=0.12) Multivariate logistic regression analysis demonstrated that rapid virological response (viral clearance during the first 4 weeks of treatment, odds ratio=22.1, p<0.001) and adherence (odds ratio=3.1, p=0.05) were predictive factors associated with SVR, whilst previous occurrence of HCC was not associated with SVR (Odds ratio=0.4, p=0.09). The incidence of severe adverse events did not differ between the two groups. CONCLUSIONS: The study proved the feasibility of pegIFN/RBV therapy with current treatment guidelines in CHC patients after successful eradication of HCC, with careful monitoring.

BACKGROUND/AIMS: Pretreatment insulin resistance (IR) is associated with treatment response to peginterferon plus ribavirin (PegIFN/RBV) combination therapy in chronic hepatitis C (CHC) infection. However, the impact of PegIFN/RBV therapy on both IR and ß-cell function in CHC patients has rarely been investigated. METHODS: A total of 277 non-diabetic patients treated with PegIFN-α and weight-based RBV, with 80/80/80 adherence, were recruited. Their IR and ß-cell function by homeostasis model assessment model (HOMA-IR and HOMA-%B) before treatment and at 24 week after treatment [end of follow-up (EOF)] was measured. RESULTS: A sustained virological response (SVR) was achieved by 79.4% (220/277) of all patients: 63.6% (75/118) of genotype-1 and 91.2% (145/159) of genotype-non-1 patients. There was no significant change of HOMA-IR post-therapy (2.25 ± 2.46 vs 2.04 ± 2.12, P=0.42). By contrast, there was a significant reduction of HOMA-%B of all patients at EOF (122.9 ± 145.2 vs 92.4 ± 73.2, P=0.001), particularly in those responders (119.1 ± 142.1 vs 89.6 ± 70.3, P=0.002). In 80 patients with high baseline HOMA-IR, both HOMA-IR and HOMA-%B decreased significantly at EOF, irrespective of SVR achievement. CONCLUSION: This study demonstrated pancreatic ß-cell function was ameliorated by PegIFN/RBV therapy in CHC patients, particularly in those responders.

BACKGROUND AND AIM: Cytokines activation is a common feature in chronic hepatitis C (CHC) infection. Visfatin, as a recently-recognized adipocytokine, may correlate with metabolic abnormalities. We aimed to elucidate the characteristics of visfatin in CHC patients. METHODS: This retrospective study included 102 treatment-naïve CHC patients and 97 sex-/age-matched healthy adults. Serum visfatin levels were examined by an enzyme linked immunosorbent assay test. The correlation between visfatin and hepatitis C virus (HCV) infection in terms of virological, metabolic, and histopathological profiles was analyzed. The impact of visfatin on the treatment response to pegylated interferon plus ribavirin (PEGIFN/RBV) therapy was also assessed. RESULTS: The visfatin level was correlated significantly with fibrosis scores (r = 0.23, P = 0.02) in CHC patients. A significant higher visfatin level was observed in CHC patients with histological activity index scores of mild and more (P = 0.01) and advanced fibrosis (P = 0.04). The mean visfatin level (0.81 ± 0.28 log ng/mL) of 26 CHC patients with metabolic syndrome was significantly lower than their counterparts (0.95 ± 0.30 log ng/mL) (P = 0.03). There was no significant correlation between visfatin and HCV genotypes, viral load, and treatment response to PEGIFN/RBV therapy. Multiple logistic regression analyses demonstrated that metabolic syndrome was the leading negative variable (odds ratio = 0.09, 95% confidence interval = 0.02-0.46, P = 0.004) associated with high visfatin level, followed by advanced fibrosis (odds ratio = 2.88, 95% confidence interval = 1.06-6.78, P = 0.03). CONCLUSIONS: Serum visfatin was correlated with disease severity and metabolic syndrome in CHC patients.

BACKGROUND: The present study evaluated the efficacy and safety of pegylated interferon (PegIFN)/ribavirin treatment in elderly patients with hepatitis C virus (HCV) infection. METHODS: Seventy elderly patients with hepatitis C virus (HCV) infection (group A; age, > or = 65 years) and 140 sex- and HCV genotype-matched controls (group B; age, 50-64 years) were allocated to receive a PegIFN-alpha-2a/ribavirin standard-of-care regimen. RESULTS: Group A had a significantly higher rate of treatment discontinuation (21.4% vs 6.4%; P = .001) and grade 3 or 4 adverse events (34.3% vs 20%; P = .002) than group B. In intention-to-treat analysis, the sustained virologic response (SVR) rate was substantially lower in group A than in group B (67.1% vs 78.6%; P = .07). The inferiority of the SVR rate in group A was observed among patients with HCV genotype 1 (HCV-1) (51.9% vs 75.9%; P = .03) but not among patients with HCV genotype 2 or 3 (HCV-2/3) (76.7% vs 80.2%; P = .65). Among patients in group A who had a rapid virologic response, those infected with HCV-1 and those infected with HCV-2/3 had similar SVR rates (80% and 87.9%, respectively). For patients receiving treatment for >80% of its expected duration, SVR rates were similar between the 2 groups (80.4% vs 82.6%, respectively), regardless of viral genotype. CONCLUSIONS: Older patients with HCV infection, especially those in the subgroup infected with HCV-1, had a greater frequency of adverse events and poorer adherence to the standard-of-care regimen, which may be the major reason for treatment inferiority.

OBJECTIVES: Hepatitis C virus (HCV) infection is the leading cause of cirrhosis and hepatocellular carcinoma worldwide. Tzukuan, located in the southwestern area of Taiwan, is an HCV hyperendemic area (>30%). This study aimed to assess the changing epidemiological characteristics of HCV infection and to evaluate the long-term outcomes after the implementation of public health strategies for two decades. DESIGN: A population-based retrospective cohort study. SETTING: A comprehensive care programme was implemented, namely COMPACT Study, in Tzukuan since 1997. PARTICIPANTS: A total of 10 714 residents participated the screening. OUTCOME MEASURES: The HCV status, demographic and clinical profiles of the participants were recorded and validated annually from 2000 through 2019. RESULTS: The HCV infection prevalence rates were 21.1% (1076/5099) in 2000-2004, 18.8% (239/1269) in 2005-2009, 14.1% (292/2071) in 2010-2014 and 10.3% (234/2275) in 2015-2019 (p for trend test <0.0001). Among them, 1614 underwent repeated tests during the follow-up period. The annual incidence rates were 0.54% in 2005-2009, 0.4% in 2010-2014 and 0.22% in 2015-2019, respectively (p=0.01). In addition to old age, lower education level was a major risk factor for HCV infection across different periods. HCV infection prevalence rate among those illiterates reached 40.9%, followed by 28.5% in those with elementary school level, and <10% in those with high school or higher levels. The major risk factor has shifted from iatrogenic exposure in 2000-2009 to household transmission after 2010. CONCLUSIONS: HCV infection has been decreasing and the epidemiological features are changing in the hyperendemic area by continuing education, prevention and treatment strategies.

BACKGROUND AND AIM: A number of hepatitis C virus (HCV) patients without a rapid virological response (RVR) achieved a sustained virological response (SVR) with peginterferon-alpha-2a/ribavirin. The aim of this study was to identify factors associated with SVR in non-RVR patients. METHODS: Baseline and on-treatment factors were used to explore the prognostic factors for SVR in 113 HCV genotype-1 (HCV-1) and 20 HCV-2 non-RVR patients in two randomized trials. RESULTS: The SVR rate in HCV-1 patients with a complete early virological response (cEVR) and partial early virological response was 91.9% versus 45% (P < 0.001) and 21.4% versus 10% (P = 0.62), respectively, after 48 and 24 weeks of treatment. The SVR rate in HCV-2 patients with a cEVR was 90.9% versus 57.1% (P = 0.25), respectively, after 24 and 16 weeks of treatment. Multivariate analysis showed that cEVR and standard regimen were independently associated with SVR. Viral kinetic study revealed that HCV viral loads < 10,000 IU/mL at week 4 were the best predictor of cEVR for both HCV-1 and HCV-2 non-RVR patients with the accuracy of 81% and 95%, respectively, and also of SVR with the accuracy of 78% and 92%, respectively, in patients receiving standard of care. The most important independent predictors for cEVR were HCV viral loads < 10(4) IU/mL at week 4, followed by increased ribavirin dose within 12 weeks of treatment. CONCLUSIONS: Achieving a cEVR with standard of care is the most important predictor of SVR in non-RVR patients. Week 4 viral loads < 10,000 IU/mL could accurately predict cEVR early and following SVR in non-SVR patients.
