Direct-acting antiviral agents (DAA) for hepatitis C virus (HCV) are not effective for hepatitis B virus (HBV), which may be suggestive of reactivation of anti-HBe hepatitis during interferon (IFN)-free DAA therapy in HBV/HCV co-infected patients with inactive HBV. A 69-year-old male patient was diagnosed with chronic hepatitis due to HBV/HCV co-infection with serum levels of alanine aminotransferase (ALT) of 94 U/L, HCV RNA of 4.2 log IU/mL and HBV DNA of 2.5 log copies/mL. HCV was thought to be responsible for the hepatitis activity because of low level of HBV core-related antigen (3.1 log U/mL). He was treated with combination therapy of daclatasvir and asunaprevir. Serum ALT gradually increased, and reached 237 U/L on day 43 in spite of undetectable HCV RNA. Serum HBV DNA was increasing to 7.0 log copies/mL at that time. The treatment was stopped due to suspicion of drug-induced liver injury and/or HBV reactivation. Administration of entecavir reduced HBV DNA levels, followed by improvement in ALT levels. This report proposes that close monitoring of HBV DNA during the anti-HCV DAA therapy and the commencement of anti-HBV therapy with nucleoside analogs after the increase of HBV DNA should be considered in patients with HBV/HCV co-infection. © 2016 The Japan Society of Hepatology.

Aim: We conducted this prospective study to elucidate the long-term outcome and incidence of hepatocellular carcinoma (HCC) development after nucleos(t)ide analog (NA) treatment in patients with chronic hepatitis B (CHB) or cirrhosis. Methods: CHB or cirrhosis patients without past NA treatment or HCC were started on entecavir (ETV) or lamivudine (LVD), and prospectively followed up with monthly blood tests, and with abdominal imaging every 6months in CHB and every 3months in cirrhosis patients. Results: A total of 256 subjects with CHB (n=194) or cirrhosis (n=62) received ETV (n=129) or LVD (n=127) for 4.25years (range: 0.41-10.0). After NA treatment, serum HBV DNA, alanine aminotransferase and α-fetoprotein (AFP) dropped significantly, along with significant increases in serum albumin and prothrombin time. Drug-resistance developed in 60 cases in the LVD group and in only one case in the ETV group. HCC developed in 35 patients, and the incidence at years 1, 3, 5, 7 and 10 was significantly higher in patients with cirrhosis (8.1%, 17.5%, 43.2%, 46.7% and 53.4%, respectively) than chronic hepatitis (1.6%, 3.5%, 3.5%, 7.1% and 29.6%, respectively), with no difference between ETV and LVD. After NA treatment, the sensitivity/specificity for HCC of AFP and des-γ-carboxy prothrombin (DCP) was 45.7%/97.3% and 33.3%/96.2%, respectively, with the specificity of AFP being higher than at baseline (64.4%), at the cut-off of 10ng/mL. Conclusion: NA exerted a long-term efficacy and improved hepatic reservation in CHB and cirrhosis. After NA treatment, AFP dropped to lower than 10ng/mL with marked elevation of specificity, leading to an earlier detection of HCC. © 2011 The Japan Society of Hepatology.

We herein report the case of an 85-year-old woman presenting with right internal jugular vein candidal thrombophlebitis associated with central venous catheters (CTCVC). The infecting agent was Candida albicans, which caused recurrent candidemia five times in total. Micafungin (MCFG) alone was ineffective; however, the combination of MCFG with fosfluconazole (F-FLCZ) successfully treated the patient without a need for any anticoagulant or surgical therapies. To the extent of our knowledge, this is the first report of CTCVC being successfully treated with a combination of F-FLCZ and MCFG. These new antifungal agents have better efficacy, tolerability and bioavailability; therefore, they can be useful alternatives to classical combination therapies such as amphotericin-B and 5-fluorocytosine. © 2013 The Japanese Society of Internal Medicine.

Objectives: The aim of this study was to evaluate the impact of olmesartan on progression of coronary atherosclerosis. Background: Prior intravascular ultrasound (IVUS) trial results suggest slowing of coronary atheroma progression with some medicines but have not shown convincing evidence of regression with angiotension-II receptor blocking agents. Methods: A prospective, randomized, multicenter trial-OLIVUS (Impact of OLmesartan on progression of coronary atherosclerosis: evaluation by IntraVascular UltraSound)-was performed in 247 stable angina pectoris patients with native coronary artery disease. When these patients underwent percutaneous coronary intervention for culprit lesions, IVUS was performed in their nonculprit vessels (without angiographically documented coronary stenosis [<50%]). Patients were randomly assigned to receive 10 to 40 mg of olmesartan or control and treated with a combination of beta-blockers, calcium channel blockers, diuretics, nitrates, glycemic control agents, and/or statins per physician's guidance. Serial IVUS examinations (baseline and 14-month follow-up) were performed to assess coronary atheroma volume. Volumetric IVUS analyses included lumen, plaque, vessel volume, percent atheroma volume (PAV), percent change in total atheroma volume (TAV) and PAV. Results: Patient characteristics and blood pressure control were identical between the 2 groups. However, follow-up IVUS showed significantly decreased TAV and percent change in PAV in the olmesartan group (5.4% vs. 0.6 % for TAV and 3.1% vs. -0.7% for percent change in PAV, control vs. olmesartan, p < 0.05 for all). Conclusions: These observations suggest a positive role in a potentially lower rate of coronary atheroma progression through the administration of olmesartan, an angiotension-II receptor blocking agent, for patients with stable angina pectoris. © 2010 American College of Cardiology Foundation.

The OLmesartan on the progression of coronary atherosclerosis: evaluation by IntraVascular UltraSound (OLIVUS) trial demonstrated that an angiotensin II receptor blocker, olmesartan, reduces the rate of coronary atheroma progression as evaluated by intravascular ultrasound in patients with stable angina pectoris undergoing percutaneous coronary intervention. This substudy examined the impact of olmesartan on serum biomarkers and the relationship between biomarker changes and atheroma progression. Patients in the OLIVUS trial (n = 247) were randomly assigned to a control group or the olmesartan group. A subgroup of these patients (n = 135, 55 %) was analyzed at baseline and at 14 months. Patients' characteristics and blood-pressure control were identical between the control group (n = 65) and the olmesartan group (n = 70), and also between the subpopulation and total population. The change in the level of high-sensitivity C-reactive protein (hs-CRP) (mg/l) and adiponectin (μg/ml) was significantly greater in the olmesartan group than in the control group (between-group differences: 0.5 and -0.7; 95 % confidence interval: 0.2-0.8 and -1.3 to -0.1; P = 0.001 and 0.02, respectively). Multiple regression analysis revealed that the nominal changes in total atheroma volume and percent atheroma volume were significantly associated with the nominal change in hs-CRP in the olmesartan group but not in the control group. Olmesartan reduced hs-CRP in patients with stable angina, and this correlated with the change in coronary atheroma. © 2013 Springer.
