Daclatasvir (DCV) and asunaprevir (ASV) combination therapy has been primarily used in patients without NS5A L31 or Y93 resistance-associated substitutions (RASs) before treatment. We examined the characteristics of patients without these baseline RASs who did not achieve hepatitis C virus eradication with DCV and ASV combination therapy and identified new baseline NS5A RASs that are closely associated with failure of combination therapy.Three hundred thirty-five patients with hepatitis C virus genotype 1 infection with no NS5A L31, NS5A Y93, and NS3 D168 RASs before DCV and ASV combination therapy and no history of protease inhibitor therapy were enrolled. All RASs were evaluated by direct sequencing.Sustained virologic response at 12weeks (SVR12) was achieved in 297 patients (89%). Patients with NS5A Q24, L28, and/or R30 RASs or concomitant NS5A F37 and Q54 RASs had a significantly lower SVR12 rate than patients without these RASs (70% vs 92%, p<0.001 and 79% vs 92%, p=0.002 respectively). Multivariate analysis showed that NS5A Q24, L28, and/or R30 RASs and concomitant NS5A F37 and Q54 RASs were significantly associated with virologic failure. The SVR12 rate in patients without NS5A Q24, L28, and/or R30 RASs and concomitant NS5A F37 and Q54 RASs was 96.2% (202/210).In patients without NS5A L31 or Y93 RASs, the presence of NS5A Q24, L28, and/or R30 RASs and concomitant NS5A F37 and Q54 RASs at the baseline was associated with failure of DCV and ASV combination therapy. The coexistence of baseline RASs other than NS5A L31 and Y93 may affect the therapeutic effectiveness of DCV and ASV combination therapy.

Aims: Our study addressed potential associations between fatty liver and small, dense low-density lipoprotein cholesterol (sd-LDL-C) levels using a cross-sectional analysis. Methods: We enrolled 476 male subjects. Serum sd-LDL-C concentrations were determined using precipitation assays. Results: Subjects were divided into four groups based on triglyceride (TG) and LDL-C levels: A, TG<150 mg/dl and LDL-C<140 mg/dl; B, TG<150 mg/dl and LDL-C ≥ 140 mg/dl; C, TG ≥ 150 mg/dl and LDL-C<140 mg/dl; and D, TG ≥150 mg/dl and LDL-C ≥ 140 mg/dl. sd-LDL-C levels and the prevalence of fatty liver were significantly higher in groups B, C, and D than in group A. Subjects were also categorized into four groups based on serum sd-LDL-C levels; the prevalence of fatty liver significantly increased with increasing sd-LDL-C levels. Additionally, logistic regression analysis revealed an independent association between sd-LDL-C concentrations and fatty liver using such potential confounders as obesity and hyperglycemia as variables independent of elevated TG or LDL-C levels. Conclusions: Fatty liver is a significant determinant of serum sd-LDL-C levels independent of the presence of obesity or hyperglycemia. Fatty liver may alter hepatic metabolism of TG and LDL-C, resulting in increased sd-LDL-C levels. © 2012 Hosoyamada et al.; licensee BioMed Central Ltd.

Background: The prevalence of diabetes mellitus (DM) has been increasing. The present study was carried out to examine the relationship between this increase and fatty liver.Methods: Japanese participants who underwent regular health examinations in 1991, 1996, 2001, 2006, and 2011 were enrolled. Fatty liver was diagnosed using ultrasonography. DM was defined as requiring the use of medication for DM, having a fasting blood glucose level ≥126 mg/dl, or hemoglobin A1c level ≥6.5 %.Results: Logistic regression analysis on data from 11,235 participants (6,882 men and 4,271 women) in 2011 revealed that the association between fatty liver and DM was independent of age, body composition, and other confounders [odds ratio (OR) 1.97, 95 % confidence interval (95 % CI) 1.66–2.32 in men, and OR, 3.12; 95 % CI, 2.29–4.26 in women]. In 2006, 5,318 participants did not have DM and were able to be followed up in 2011. Fatty liver in 2006 was an independent predictor of DM in 2011 [OR 1.73 (95 % CI 1.20–2.50) in men, 4.13 (2.16–8.10) in women]. The prevalence of DM increased significantly during the 20-year period examined among both men (6.0, 8.9, 10.0, 10.8, 12.0 %, P < 0.001) and women (3.3, 4.5, 4.2, 4.1, 5.1 %, P = 0.004), accompanied with an increased prevalence of fatty liver among both men (10.8, 26.3, 33.8, 36.7, and 38.0 %, P < 0.001) and women (6.5, 16.7, 22.2, 21.3, and 20.8 %, P < 0.001).Conclusion: Fatty liver independently predicts both present and future DM. Fatty liver may play an important role in the recent increases in the prevalence of DM. © 2013, Springer Japan.

Background: Alcohol is considered to be a major cause of fatty liver (FL). In contrast, however, recent investigations have suggested that moderate alcohol consumption is protective against FL. To clarify the role of alcohol consumption in FL development, we examined the association between drinking patterns and FL prevalence. Methods: We enrolled 9,886 male participants at regular medical health checks. Each subject's history of alcohol consumption was determined by questionnaire. The subjects were classified according to alcohol consumption as non-, light, moderate, and heavy drinkers (0, <20, 20-59, and ≥60 g/day, respectively). FL was defined by ultrasonography. Independent predictors of FL were determined by logistic regression analysis. Results: The prevalence of FL displayed a "U-shaped curve" across the categories of daily alcohol consumption (non-, 44.7%; light, 39.3%; moderate, 35.9%; heavy drinkers, 40.1%; P < 0.001). The prevalence of FL was associated positively with body mass index and other obesity-related diseases and inversely with alcohol consumption (light, odds ratio [OR] 0.71, 95% confidence interval [CI] 0.59-0.86; moderate, OR 0.55, CI 0.45-0.67; heavy, OR 0.44, CI 0.32-0.62) as determined by multivariate analysis after adjusting for potential confounding variables. In addition, examination of drinking patterns (frequency and volume) revealed that the prevalence of FL was inversely associated with the frequency of alcohol consumption (≥21 days/month) (OR 0.62, CI 0.53-0.71) but not with the volume of alcohol consumed. Conclusions: Our observations suggest that alcohol consumption plays a protective role against FL in men, and consistent alcohol consumption may contribute to this favorable effect. © Springer 2010.

Background Metabolic syndrome, which includes obesity, hyperglycemia, dyslipidemia, and hypertension, is a major risk factor for the development of nonalcoholic fatty liver disease (NAFLD). Cigarette smoking is a well-known risk factor for metabolic syndrome, but the epidemiological impact of cigarette smoking on development of NAFLD is unclear. Methods In this retrospective study, 2,029 subjects underwent a complete medical health checkup in 1998 and again in 2008. Those who were positive for hepatitis B surface antigen or hepatitis C virus antibody, or had an alcohol intake of >20 g/day as assessed by questionnaire, were excluded. Fatty liver was diagnosed by abdominal ultrasonography. Independent risk factors associated with the development of NAFLD were determined by multiple logistic regression analysis. Smoking status was expressed using the Brinkman index (BI), which was calculated as the number of cigarettes smoked per day multiplied by the number of years of smoking. Results Of 1,560 subjects without NAFLD in 1998, 266 (17.1%) were newly diagnosed with NAFLD in 2008. Multiple logistic analysis identified age [adjusted odds ratio (AOR) 0.95, 95% confidence interval (95% CI) 0.94-0.97], male sex (AOR 1.46, 95% CI 1.01-2.10), body mass index C25 (AOR 3.08, 95% CI 2.20-4.32), dyslipidemia (AOR 1.79, 95% CI 1.25-2.58) and cigarette smoking (AOR 1.91, 95% CI 1.34-2.72) as risk factors associated with the development of NAFLD. Smoking status at baseline was also associated with the development of NAFLD (BI 1-399: AOR 1.77, 95% CI 1.02-3.07, BI C400: AOR 2.04, 95% CI 1.37-3.03). Conclusion Cigarette smoking is an independent risk factor for onset of NAFLD.

We conducted transhepatic arterial infusion chemotherapy (TAI) was on 62 patients with highly advanced hepatocellular carcinoma without distant metastases and therapeutic outcome was compared with 18 who were untreated. TAI significantly prolonged the survival of the patients, and was the most important prognostic factor on multivariate analysis. The following 3 regimens for trans-arterial injection were compared: A, a combination of a bolus hepatic artery injection of 3 agents (cisplatin, mitomycin-C and epirubicin)+low dose 5-fluorouracil+cisplatin (FP); B, low-dose FP alone; and C, bolus intrahepatic artery injection of the above 3 agents combined without FP. Regimen A yielded in the most effective survival rate, with an efficacy rate of 41.6% and a CR of about 20%. These results indicate that TAI is an effective therapeutic modality, and the dose FP combined with a bolus intrahepatic arterial infusion may improve outcomes in advanced liver cancer.
