RESUMO
AIMS: Hepatocellular carcinoma (HCC) develops even in patients with hepatitis C virus (HCV) eradication by direct-acting antiviral agents. Fatty liver and metabolic dysfunction are becoming major etiologies of HCC. We aimed to evaluate the impact of metabolic dysfunction-associated steatotic liver disease (MASLD), a new definition of steatotic liver disease, on the development of HCC after HCV eradication. METHODS: We enrolled 1280 elderly patients with HCV eradication and no history of HCC. We evaluated α-fetoprotein (AFP), Fibrosis-4 index and MASLD after 24 weeks of sustained virological response. Decision tree analysis was used to investigate factors associated with HCC development after HCV eradication. RESULTS: A total of 86 patients (6.7%) developed HCC during the follow-up period (35.8 ± 23.7 months). On multivariate analysis, serum AFP level (HR 1.08, CI 1.04-1.11, P = 0.0008), Fibrosis-4 index (HR 1.17, CI 1.08-1.26, P = 0.0007), and MASLD (HR 3.04, CI 1.40-6.58, P = 0.0125) at 24 weeks of sustained virological response were independent factors associated with HCC development. In decision tree analysis, the initial classifier for HCC development was AFP ≥7 ng/mL. However, in patients with AFP <7 ng/mL, MASLD, rather than Fibrosis-4 index, was the classifier for HCC development. No significant difference was observed in the cumulative incidence of HCC between patients with AFP ≥7 ng/mL and patients with AFP <7 ng/mL and MASLD. CONCLUSION: MASLD at 24 weeks of sustained virological response is a risk factor for HCC development in elderly patients with HCV eradication. Additionally, decision tree analysis revealed that MASLD was associated with HCC development, even in patients with serum AFP levels <7 ng/mL.
RESUMO
AIMS: The real-world efficacy of sofosbuvir/velpatasvir treatment for patients with hepatitis C virus-related decompensated cirrhosis is unclear. We aimed to identify factors that improve liver functional reserve after treatment. METHODS: This was a multicenter retrospective study of 12-week sofosbuvir/velpatasvir treatment. A total of 48 patients with Child-Pugh (CP) class B or C were enrolled at 11 institutions. We evaluated changes in liver functional reserve at 24 weeks post-treatment. RESULTS: At baseline, 40 and eight patients were CP class B and C, respectively. The overall rate of sustained virologic response 12 weeks post-treatment was 95.8% (46/48). Serum albumin, alanine aminotransferase and α-fetoprotein levels, and the FIB-4 index were significantly improved post-treatment (P < 0.05). Among patients who achieved sustained virologic response 12 weeks post-treatment, those with CP class A increased from 0 to 24 patients (56%) at 24 weeks post-treatment. In multivariate analysis, body mass index (BMI) ≥25 was an independent factor that inhibited CP class improvement (P < 0.05). In decision tree analysis, after treatment, the initial divergent variable for CP class improvement was hepatic encephalopathy, followed by serum sodium level and BMI. CONCLUSION: Sofosbuvir/velpatasvir treatment improved the liver functional reserve in patients with hepatitis C virus-related decompensated cirrhosis at 24 weeks post-treatment. However, BMI ≥25 inhibited improvement in CP class. Additionally, decision tree analysis revealed that a combination of hepatic encephalopathy, serum sodium levels, and BMI were diversity profiles associated with no improvement in liver functional reserve after the treatment.
RESUMO
AIM: Agile 3+ and Agile 4 scores, based on liver stiffness measurement (LSM) by transient elastography and clinical parameters, were recently reported to be effective in identifying advanced fibrosis and cirrhosis in nonalcoholic fatty liver disease (NAFLD). This study aimed to validate the utility of these scores in Japanese patients with NAFLD. METHODS: Six hundred forty-one patients with biopsy-proven NAFLD were analyzed. The severity of liver fibrosis was pathologically evaluated by one expert pathologist. The LSM, age, sex, diabetes status, platelet count, and aspartate aminotransferase and alanine aminotransferase levels were used to calculate Agile 3+ scores, and the parameters above excluding age were used for Agile 4 scores. The diagnostic performance of the two scores was evaluated using receiver operating characteristic (ROC) curve analysis. Sensitivity, specificity, and predictive values of the original low cut-off (for rule-out) value and high cut-off (for rule-in) value were tested. RESULTS: For diagnosis of fibrosis stage ≥3, the area under the ROC (AUROC) was 0.886, and the sensitivity of the low cut-off value and the specificity of the high cut-off value were 95.3% and 73.4%, respectively. For diagnosis of fibrosis stage 4, AUROC, the sensitivity of the low cut-off value, and the specificity of the high cut-off value were 0.930, 100%, and 86.5%, respectively. Both scores had higher diagnostic performance than the FIB-4 index and the enhanced liver fibrosis score. CONCLUSIONS: Agile 3+ and Agile 4 are reliable noninvasive tests to identify advanced fibrosis and cirrhosis in Japanese NAFLD patients with adequate diagnostic performance.
RESUMO
BACKGROUND AND AIM: The prevalence of glucose intolerance in chronic liver disease patients is high, but glucose intolerance may be overlooked in a single blood test. The purpose of this study is to evaluate blood glucose variability in patients with chronic liver disease by a continuous glucose monitoring system (CGMS) and to examine the discrepancy between hemoglobin A1c (HbA1c) levels estimated from average blood glucose levels and HbA1c. METHODS: This study included 335 patients with chronic liver disease associated with glucose intolerance. A fasting blood test and 72-h CGMS were performed. The estimated HbA1c was calculated from the average blood glucose level, and the correlation between hepatic functional reserve and blood glucose-related parameters was analyzed. From the obtained data, we created a new formula to calculate HbA1c without using CGMS. RESULTS: As hepatic functional reserve decreased, average blood glucose and insulin resistance increased while HbA1c decreased (P < 0.0001). The discrepancy between the estimated HbA1c calculated from the mean blood glucose level and the serum HbA1c (ΔHbA1c) increased as the liver reserve decreased. Using multiple regression analysis, a formula based on fasting blood glucose, HbA1c, body mass index, albumin, and liver function was constructed, and its validity was demonstrated in a study using a different control group. CONCLUSIONS: Hemoglobin A1c may be underestimated because of decreased hepatic functional reserve. CGMS was useful in assessing accurate glycemic control of blood glucose and in detecting postprandial hyperglycemia and nocturnal hypoglycemia. Patients with chronic hepatic impairment should be corrected for hepatic functional reserve before glycemic control.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide and one of the leading causes of hepatocellular carcinoma and liver transplantation. Moreover, patients with NAFLD frequently complain of non-specific symptoms including fatigue, abdominal discomfort, as well as anxiety, and NAFLD is reported to affect patient-reported outcomes (PROs). Thus, for clarifying the total burden of NAFLD, it is crucial to assess all associated outcomes, including not only clinical and economic outcomes but also PROs. PROs are thought to reflect what is happening in one's daily life and is an important way patients and health-care professionals communicate. There are various instruments for the assessment of PROs. Recently, a NAFLD/non-alcoholic steatohepatitis (NASH)-specific instrument called "Chronic Liver Disease Questionnaire (CLDQ)-NAFLD/NASH" has been developed. CLDQ-NAFLD/NASH comprises six domains: (i) abdominal symptoms, (ii) activity/energy, (iii) emotional health, (iv) fatigue, (v) systemic symptoms, and (vi) worry. CLDQ-NAFLD/NASH has demonstrated excellent internal consistency, face validity, content validity, and test-retest reliability. It has been sufficiently validated in two international phase 3 clinical trials. In this review, we summarize features of various instruments for assessing PROs by focusing on CLDQ-NAFLD/NASH. We also examine the validity of CLDQ-NAFLD/NASH in Japanese patients and alterations in CLDQ-NAFLD/NASH score in Japanese patients with significant hepatic fibrosis. Moreover, we discuss the utility of CLDQ-NAFLD/NASH in phase 3 clinical trials and in a real-world clinical setting.

AIM: The Enhanced Liver Fibrosis (ELF) test comprises a logarithmic algorithm combining three serum markers of hepatic extracellular matrix metabolism. We aimed to evaluate the performance of ELF for the diagnosis of liver fibrosis and to compare it with that of liver stiffness measurement (LSM) by FibroScan in non-alcoholic fatty liver disease. METHODS: ELF cut-off values for the diagnosis of advanced fibrosis were obtained using receiver operating characteristic analysis in patients with biopsy-confirmed non-alcoholic fatty liver disease (training set; n = 200). Diagnostic performance was analyzed in the training set and in a validation set (n = 166), and compared with that of LSM in the FibroScan cohort (n = 224). RESULTS: The area under receiver operating characteristic curve was 0.81 for the diagnosis of advanced fibrosis, and the ELF cut-off values were 9.34 with 90.4% sensitivity and 10.83 with 90.6% specificity in the training set, and 89.8% sensitivity and 85.5% specificity in the validation set. There was no significant difference in the area under the receiver operating characteristic curve between ELF and LSM (0.812 and 0.839). A combination of ELF (cut-off 10.83) and LSM (cut-off 11.45) increased the specificity to 97.9% and the positive predictive value, versus ELF alone. Sequential use of the Fibrosis-4 index (cut-off 2.67) and ELF (cut-off 9.34) increased the sensitivity to 95.9%. CONCLUSIONS: ELF can identify advanced liver fibrosis in non-alcoholic fatty liver disease, and its diagnostic accuracy is comparable to that of FibroScan. According to the clinical setting, combinations or sequential procedures using other non-invasive tests complement the diagnostic performance of ELF for the identification of advanced fibrosis.
RESUMO
This study explores the role of gender-based decision-making in the adoption of improved maize varieties. The primary data were collected in 2018 from 560 farm households in Dawuro Zone, Ethiopia, and were comparatively analyzed across gender categories of households: male decision-making, female decision-making and joint decision-making, using a double-hurdle model. The results show that the intensity of improved maize varieties adopted on plots managed by male, female, and joint decision-making households are significantly different. This effect diminishes in the model when we take other factors into account. Using the gender of the heads of households and agricultural decision-maker, the current study did not find significant evidence of gender difference in the rate and intensity of adoption of improved maize varieties. The intensity of adoption of improved maize varieties is lower for female-headed households where decisions are made jointly by men and women, compared to the male-headed households where decisions are made jointly. As the economic status is a key driver of adoption of improved maize varieties, it is recommended that the policies and programs that aim at developing and disseminating quality maize seeds in southern Ethiopia should emphatically support economically less endowed but more gender egalitarian joint decision-making households, especially female-headed ones.
RESUMO
In Japan, hepatitis B or C virus infection has been a major health issue. For the prevention of liver-related deaths, multifaceted strategies have been taken against hepatitis virus. In fiscal year (FY) 2002, nationwide screening for hepatitis was started as a part of health examinations provided by municipal governments. From FY2007, the hepatitis treatment network has been strengthened by the nationwide establishment of regional government-based hepatitis treatment systems, comprising linked regional core centers, specialized institutions for hepatitis treatment, primary care physicians, and regional governments. Special subsidy program for patients with viral hepatitis was started at FY2008. The range of coverage has been expanding from patients treated with interferon to those on nucleotide analogs or interferon-free therapies, including drug prices and examination expenses. The Basic Act on Hepatitis Measures was established in 2009. The Basic Guidelines for Promotion of Control Measures for hepatitis was issued in 2011, comprising nine principles in order to promote measures for hepatitis B and C. The Hepatitis Information Center was established in 2008. Its mission is to provide up-to-date hepatitis-related information, supporting collaboration between regional core centers, and training medical personnel. The revision of the above-mentioned Basic Guidelines in 2016 set the target as the reduction of patients progressing to cirrhosis and/or liver cancer. Achieving this goal definitely requires active collaboration among the national and local governments, regional core centers, and the Hepatitis Information Center, and participation by medical personnel, patients, and people with awareness.
RESUMO
BACKGROUND It is important to avoid relapse in autoimmune hepatitis (AIH) because repeated multiple relapses have been associated with a worse prognosis. However, risk factors for relapse before initiation of treatment are not fully understood. The aim of this study was to find predictive markers for relapse of type 1 AIH. MATERIAL AND METHODS We reviewed the records of 53 patients diagnosed with type 1 AIH based on the revised scoring system proposed by the International Autoimmune Hepatitis Group (IAIHG) between 2009 and 2014 at 4 hospitals belonging to the Saga Study Group of Liver Diseases (SASLD). We analyzed the differences in background characteristics between patients with or without relapse. RESULTS All patients achieved remission after treatment, and 9 (17%) subsequently relapsed. The relapsed patients were significantly younger and had a higher positive rate of anti-smooth muscle antibody (ASMA) than the non-relapsed patients (100% vs. 25%, P=0.0012). Moreover, relapse rate increased with titer of ASMA, while titer of antinuclear antibody was not associated with relapse rate. CONCLUSIONS ASMA is a useful predictive marker for relapse of type 1 AIH during or after withdrawal of medical therapy. More careful attention should be paid to immunosuppressive therapy in patients with high titers of ASMA.
RESUMO
BACKGROUND/AIMS: The aims of this study were to compare long-term prognosis of patients with hepatocellular carcinoma (HCC) treated with radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI). METHODOLOGY: Two hundred and thirteen patients with HCC were initially treated with PEI or RFA at Saga University Hospital between 1990 and 2004. The present study included 190 patients: 98 treated with PEI from 1990 to 1999, and 92 with RFA from 2000 to 2004. The association of treatment method with survival prognosis was evaluated by multivariate analysis. RESULTS: There were no significant differences in gender, etiology, and tumor stage between the two groups. Five-year survival rate in the PEI group was 40% and 51% in the RFA group. According to tumor stage, there were no differences in 5-year survival rate between the two groups for tumor stage I and III. For stage II patients, RFA had better survival than PEI (48% vs. 28%, p = 0.03). Multivariate analysis indicated that RFA was more effective for long-term survival than PEI in patients with tumor stage II (p = 0.04). CONCLUSIONS: Compared to PEI, RFA improved survival in patients with stage II HCC, indicating a therapeutic advantage of RFA.

There is an association between nonalcoholic fatty liver disease (NAFLD) and atherosclerosis, but the genetic risk of atherosclerosis in NAFLD remains unclear. Here, a single-nucleotide polymorphism (SNP) of the heat shock 70 kDa protein 8 (HSPA8) gene was analyzed in 123 NAFLD patients who had been diagnosed using a liver biopsy, and the NAFLD phenotype including the maximum intima-media thickness (Max-IMT) of the carotid artery was investigated. Patients with the minor allele (A/G or G/G) of rs2236659 showed a lower serum heat shock cognate 71 kDa protein concentration than those with the major A/A allele. Compared with the patients with the major allele, those with the minor allele showed a higher prevalence of hypertension and higher Max-IMT in men. No significant associations between the HSPA8 genotype and hepatic pathological findings were identified. In decision-tree analysis, age, sex, liver fibrosis, and HSPA8 genotype were individually associated with severe carotid artery atherosclerosis (Max-IMT ≥ 1.5 mm). Noncirrhotic men aged ≥ 65 years were most significantly affected by the minor allele of HSPA8. To predict the risk of atherosclerosis and cardiovascular disease, HSPA8 SNP genotyping might be useful, particularly for older male NAFLD patients.

Sodium glucose cotransporter-2 inhibitors (SGLT2is) are now widely used to treat diabetes, but their effects on nonalcoholic fatty liver disease (NAFLD) remain to be determined. We aimed to evaluate the effects of SGLT2is on the pathogenesis of NAFLD. A multicenter, randomized, controlled trial was conducted in patients with type 2 diabetes with NAFLD. The changes in glycemic control, obesity, and liver pathology were compared between participants taking ipragliflozin (50 mg/day for 72 weeks; IPR group) and participants being managed without SGLT2is, pioglitazone, glucagon-like peptide-1 analogs, or insulin (CTR group). In the IPR group (n = 25), there were significant decreases in hemoglobin A1c (HbA1c) and body mass index (BMI) during the study (HbA1c, -0.41%, P < 0.01; BMI, -1.06 kg/m2 , P < 0.01), whereas these did not change in the CTR group (n = 26). Liver pathology was evaluated in 21/25 participants in the IPR/CTR groups, and hepatic fibrosis was found in 17 (81%) and 18 (72%) participants in the IPR and CTR groups at baseline. This was ameliorated in 70.6% (12 of 17) of participants in the IPR group and 22.2 % (4 of 18) of those in the CTR group (P < 0.01). Nonalcoholic steatohepatitis (NASH) resolved in 66.7% of IPR-treated participants and 27.3% of CTR participants. None of the participants in the IPR group developed NASH, whereas 33.3% of the CTR group developed NASH. Conclusion: Long-term ipragliflozin treatment ameliorates hepatic fibrosis in patients with NAFLD. Thus, ipragliflozin might be effective for the treatment and prevention of NASH in patients with diabetes, as well as improving glycemic control and obesity. Therefore, SGLT2is may represent a therapeutic choice for patients with diabetes with NAFLD, but further larger studies are required to confirm these effects.

Chronic liver disease, especially viral hepatitis, is an urgent issue in Japan. Human resource management is important to promote appropriate care for patients with chronic liver disease in medical institutions and in the community. In 2011 the Ministry of Health, Labour and Welfare in Japan started training hepatitis medical care coordinators (HMCCs). Various medical professionals (such as public health nurses, general nurses, and clinical technicians), patients, and ordinary citizens are certified as HMCCs by the prefectural government after learning about liver diseases in a training program. The training program can be optimized in accordance with the regional circumstances and basic knowledge and skills of the applicants. HMCCs encourage residents and patients to undergo a hepatitis screening test, after which positive patients undergo detailed examination, treatment, and follow-up. HMCCs contribute to the expansion of knowledge about hepatitis in their workplace and community. By 2018, there were HMCCs in all 47 prefectures of Japan. There were 20,049 HMCCs in 2019. The most common professions of HMCCs were public health nurses, followed by general nurses, hospital pharmacists, laboratory technicians, and medical social workers. After certification, the activities of HMCCs vary; to ensure that HMCCs are adequately used in medical institutions, the supervisor and physicians must recognize the importance of HMCCs and generate opportunities for HMCC activity. The training and effective utilization of HMCCs is a promising way to decrease the prevalence and mortality of chronic liver diseases in Japan.
RESUMO
We examine factors affecting the choice of marketing channels for maize among male, female, and joint decision-making farm households using data from households in Dawuro zone, southern Ethiopia. Econometric results suggest that female and joint decision-makers are more likely to sell maize to consumers or retailers in the main local market where the maize price is higher than to wholesale merchants directly from the farm. Individual decision-makers (male or female) who grow improved maize varieties are more likely to sell to wholesalers directly from the farm. This may be an indication of the effectiveness of joint decisions over individual decisions related to the market price. We also found that improved maize varieties distributed to farmers in the study area are of poor quality and that there is a lack of modern storage facilities so that farmers have to sell immediately after harvest during the lower price season. Thus, there is a need for policies promoting the distribution of high-quality maize seeds and encouraging investments in the establishment of modern maize storage facilities in the study area. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s10745-021-00252-x.
RESUMO
This study examines the impact of gender differences on maize productivity in Dawuro Zone, southern Ethiopia. Our study addressed the limitations of the previous studies in two ways. First, the study separately assessed gender differences in productivity between de facto female-headed households and de jure female-headed households and revealed that female-headed households are not homogenous. Second, the study separately examined the impacts of the covariates on male-headed households and female-headed households using an exogenous switching treatment effect model. We find the existence of gender differences in maize productivity between male-headed households and female-headed households. The maize productivity of male-headed households was overall 44.3% higher than that of female-headed households. However, if female-headed households received the same return on their resources as male-headed households, their productivity would increase by 42.3%. This suggests agricultural policy should target female-headed households to help reduce the productivity gap between male-headed households and female-headed households. Finally, the distributions of the gender differentials between male-headed households and female-headed households are more pronounced at mid-levels of productivity.
RESUMO
Liver fibrosis is associated with lifestyle-related diseases, including diabetes. The identification of diabetic patients with severe liver fibrosis is important, but a simple and reliable diagnostic procedure remains to be determined. We conducted an observational study to evaluate the performance of a FIB-4 index-based screening strategy for the diagnosis of advanced liver fibrosis in patients with diabetes or prediabetes. Two hundred and forty-two patients underwent abdominal imaging in our Study. According to the abdominal imaging findings, fatty liver, liver cirrhosis, and hepatocellular carcinoma were defined, and their association with FIB-4 index evaluated. The prevalences of liver cirrhosis and hepatocellular carcinoma in patients with a high (≥ 2.67; liver cirrhosis: 42.9%, hepatocellular carcinoma: 14.3%) FIB-4 index were significantly higher than in those with an intermediate (1.3 ≤ FIB-4 < 2.67; liver cirrhosis: 1.6%, hepatocellular carcinoma: 0.8%) or low FIB-4 index (< 1.3; liver cirrhosis: 1.2%, hepatocellular carcinoma: 0%). The diagnostic accuracy, specificity, and sensitivity of the FIB-4 index for the diagnosis of liver cirrhosis or hepatocellular carcinoma were 84.3%, 85.5%, and 89.3%, respectively, with an optimized cut-off value of 2.96 (sensitivity = 0.86, specificity = 0.98). Using an optimized cut-off value, FIB-4 index might be useful to identify liver cirrhosis or hepatocellular carcinoma in diabetes patients with high diagnostic accuracy.
RESUMO
The effect of the skin-capsular distance (SCD) on the controlled attenuation parameter (CAP) for diagnosis of liver steatosis in patients with nonalcoholic fatty liver disease (NAFLD) remains unclear. The SCD was measured using B-mode ultrasound, and the CAP was measured using the M probe of FibroScan®. According to the indications of the M probe, 113 patients with an SCD of ≤ 25 mm were included in the present study. The association between the SCD and CAP was investigated, and the diagnostic performance of the SCD-adjusted CAP was tested. The SCD showed the most significant positive correlation with the CAP (ρ = 0.329, p < 0.001). In the multiple regression analysis, the SCD and serum albumin concentration were associated with the CAP, independent of pathological liver steatosis. According to the multivariate analysis, two different formulas were developed to obtain the adjusted CAP using the SCD and serum albumin concentration as follows: adjusted CAP (dB/m) = CAP - (5.26 × SCD) and adjusted CAP (dB/m) = CAP - (5.35 × SCD) - (25.77 × serum albumin concentration). The area under the receiver operating characteristic curve for diagnosis of a steatosis score ≥ 2 of adjusted CAP was 0.678 and 0.684 respectively, which were significantly greater than the original CAP (0.621: p = 0.030 and p = 0.024). The SCD is associated with the CAP independent of liver steatosis. Adjustment of the CAP using the SCD improves the diagnostic performance of the CAP in NAFLD.

Access to imaging is limited for diagnosing nonalcoholic fatty liver disease (NAFLD) in general populations. This study evaluated the diagnostic performance of noninvasive and nonimaging indexes to predict NAFLD in the general Japanese population. Health checkup examinees without hepatitis virus infection or habitual alcohol drinking were included. Fatty liver was diagnosed by ultrasonography. The hepatic steatosis index (HSI), Zhejiang University (ZJU) index, and fatty liver index (FLI) were determined, and risk of advanced liver fibrosis was evaluated by the fibrosis-4 index. NAFLD was diagnosed in 1935 (28.0%) of the 6927 subjects. The area under the receiver operating characteristic (AUROC) curve of the HSI, ZJU index, and FLI was 0.874, 0.886, and 0.884, respectively. The AUROC of the ZJU index (p < 0.001) and FLI (p = 0.002) was significantly greater than that for the HSI. In subjects with a high risk of advanced fibrosis, the sensitivity of the HSI, ZJU index, and FLI were 88.8%, 94.4%, and 83.3% with a low cut-off value and the specificity was 98.5%, 100%, and 100% with a high cut-off value. In conclusion, all indexes were useful to diagnose NAFLD in the general Japanese population and in subjects with potentially advanced liver fibrosis.
RESUMO
Objective Despite recent advances in hepatitis C virus (HCV) treatment, some HCV-positive individuals are unaware of their infection. The present study aimed to assess the rate and age distribution in Saga Prefecture regarding i) HCV infection and HCV screening and ii) direct acting anti-viral (DAA) treatment. Methods HCV screening data collected at a medical institution or in the workplace were obtained from the administrative database in Saga Prefecture between April 1, 2008 and March 31, 2014. DAA treatment data from Saga Prefecture were obtained from the DAA treatment reimbursement recipient database between October 2014 and March 2017. Results There were 35,625 individuals who underwent HCV screening, and the HCV positive rate was 1.18% (421 individuals), which increased in an age-related manner. The screening rate in the screened populations peaked at 45-74 years of age (approximately 6%) and decreased in the younger and older generations. The estimated percentage of DAA treatment peaked at 65-74 years old (65.8%) and significantly decreased inversely with age in the younger generations; only 9.4% of HCV carriers received DAA treatment in the 20- to 34-year age group. The proportion of subjects who received a complete physical examination for DAA treatment was higher in the subjects who were screened at a medical institution than in those screened at the workplace. Conclusion The rate of subjects who underwent HCV screening and DAA treatment was not high, especially in the younger generation, in Saga Prefecture. This group should be targeted for HCV screening and treatment.
