Objective This study aims to create a method of calculating intra-abdominal visceral fat volume by using ultrasound (US). The visceral fat volume measured by US was evaluated by comparison with the volume measured by computed tomography (CT).Methods Eighty-seven patients (52 males and 35 females) were enrolled in this study. Both US and CT were performed, and the visceral fat volume was measured. Both the distance and thickness of the parameters in US were measured as follows: 1) the distance between the internal surface of the abdominal muscle and the splenic vein, 2) the distance between the internal surface of the abdominal muscle and the posterior wall of aorta on the umbilicus, and 3) the thickness of the fat layer of the posterior right renal wall.Results
Aim The predictors for the development of hepatocellular carcinoma (HCC) after direct‐acting antiviral (DAA) treatment were investigated. Methods A total of 1174 patients with chronic hepatitis C virus infection were treated with DAA therapy (sofosbuvir and ledipasvir [n = 615], sofosbuvir and ribavirin [n = 380], and daclatasvir and asunaprevir [n = 179]) and achieved sustained virologic response (SVR). The HCC development rate and the factors that might contribute to the development of HCC after the end of DAA treatment were analyzed. Results During the median observation period of 537 days, HCC developed in 33 cases. The incidence of HCC was 1.9%, 3.2%, and 4.1% at 1, 1.5, and 2 years after the end of DAA therapy, respectively. Multivariate analysis with pre‐ and post‐treatment factors identified the Fibrosis‐4 (FIB‐4) index (hazard ratio [HR] = 1.09; 95% confidence interval [CI], 1.021–1.178; P = 0.011) and post‐treatment α‐fetoprotein (AFP) (HR = 1.11; 95% CI, 1.054–1.172; P < 0.001) as independent factors that contributed to the development of HCC after DAA therapy. Using these identified parameters, a new scoring system (0 to 2 points) was established. Patients in the high‐score group (2 points) could be identified as having a significantly higher risk of HCC development, and the respective 1‐ and 2‐year cumulative incidence rates of HCC were 6.1% and 14.4%. Conclusions A high FIB‐4 index and a high post‐treatment AFP at the end of DAA treatment were the independent predictors for developing HCC after DAA treatment. For patients with these risk factors, extra attention to the possibility of HCC development is needed.
Recently, the number of patients diagnosed with WD has been increasing, not only in terms of those with classical-type WD but also in terms of elderly patients or patients with non-cirrhotic liver injury such as fatty liver and chronic hepatitis. The various clinical features of WD should be recognized and particular attention should focus on HCC as a complication.

Sex differences in the predictors for hepatocellular carcinoma (HCC) development after direct‐acting antiviral (DAA) therapy was investigated. DAA therapy was given to 1438 (663 male, 775 female) patients. Sex differences in the HCC development rate and the factors contributing to HCC development after DAA therapy were investigated. Male patients had a significantly higher cumulative HCC incidence (log‐rank test, P = .007). On multivariate analysis, the fibrosis‐4 index (HR = 1.11; 95%CI, 1.042‐1.202, P = .002) and posttreatment α‐fetoprotein (AFP) (HR = 1.11; 95%CI, 1.046‐1.197, P = .001) were found to be independent factors that contributed to HCC development following DAA therapy in female patients, whereas only posttreatment AFP (HR = 1.090; 95%CI, 1.024‐1.160, P = .007) was an independent factor in male patients. The optimal posttreatment AFP cut‐off values were set based on receiver operating characteristic curve analyses. The optimal posttreatment AFP cut‐off value was much higher in females (6.0 ng/mL) than in male (3.5 ng/mL) patients. In conclusion both in male and female patients, posttreatment AFP was an independent predictor of HCC development after DAA therapy. However, the cut‐off values differed between the sexes. In male patients, HCC could be seen in patients with relatively low posttreatment AFP levels; more careful observation might be needed in such patients.
A 31-year-old woman with Graves' disease with a 12-month-history of propylthiouracil intake and autoantibodies in the sera was admitted to our hospital. The differential diagnosis between autoimmune hepatitis and propylthiouracil-induced hepatitis was intractable. Steroid therapy was started and she showed a complete response to the treatment. Liver biopsy demonstrated acute hepatitis and plasma cell infiltration. A second liver biopsy, which was performed 10 months after starting steroid therapy, showed some inflammatory cells in the portal tracts. These findings suggest that she had been suffering from autoimmunehepatitis. (Internal Medicine 42: 331-335, 2003)
Background An unexpected recurrence of hepatocellular carcinoma (HCC) sometimes occurs in patients with hepatitis C virus (HCV) after treatment with direct-acting antivirals (DAAs). However, the characteristics of patients with HCC recurrence may differ depending on time after DAA treatment. We aimed to identify risk factors related to HCC recurrence according to time after DAA treatment. Methods Of 1663 patients with HCV treated with a DAA, 199 patients had a previous history of HCC. We defined HCC recurrence within 1 year after DAA treatment as ‘early recurrence’, and recurrence more than 1 year after as ‘late recurrence’. The different risk factors between the early and late phases of HCC recurrence after the end of DAA therapy were investigated. Results Ninety-seven patients experienced HCC recurrence during the study period. Incidences of recurrence were 29.8, 41.0, and 53.4% at 1, 2, and 3 years, respectively, after the end of DAA therapy. Multivariate analysis identified post-treatment α-fetoprotein (AFP) as an independent factor contributing to HCC recurrence in the early phase (hazard ratio, 1.056; 95% confidence interval, 1.026–1.087, p < 0.001) and post-treatment estimated glomerular filtration rate (eGFR) (hazard ratio, 0.98; 95% confidence interval, 0.96–0.99, p = 0.032) as a predictor of HCC recurrence in the late phase. Conclusion Patients with higher post-treatment AFP in the early phase and those with lower post-treatment eGFR in the late phase had a high risk of HCC recurrence. The risk factors associated with HCC recurrence after DAA treatment were different between the early and late phases.
The tolerability and efficacy of sofosbuvir and ribavirin in patients infected with hepatitis C virus (HCV) genotype 2 were investigated under actual clinical conditions. A total of 208 patients with chronic HCV genotype 2 infection were treated with sofosbuvir 400 mg and ribavirin (weight-based dosing) for 12 weeks. Treatment discontinuation and sustained virological response 12 (SVR12) were evaluated. Moreover, factors associated with SVR12, hemoglobin decreasing to less than 10 g/dL during treatment, and alanine aminotransferase (ALT) non-normalization after treatment were evaluated. In all patients, SVR12 responses were 96.1% (200/208). About 6 of 8 patients (3.8%) who did not achieve SVR12 were re-treatment patients, and eight patients who did not achieve SVR all had liver cirrhosis. Multivariate analysis also identified body mass index (OR = 0.79; P < 0.001), platelet count (OR = 0.88; P = 0.003), and estimated glomerular filtration rate (eGFR) (OR = 0.96; P = 0.007) as independent contributing factors associated with hemoglobin decreasing to less than 10 g/dL during treatment, and only Mac-2 Binding Protein Glycosylation isomer (M2BpGi) (OR = 2.46; P = 0.017) as an independent contributing factor associated with ALT non-normalization after treatment. Cirrhotic patients may have a relatively high rate of treatment failure. In patients whose M2BpGi levels are elevated, their ALT tended to not normalize after treatment completion. These patients who did not achieve normalization of ALT after sofosbuvir plus RBV treatment need more careful observation for emergence of hepatocellular carcinoma even after achievement of SVR.
