PurposeTo demonstrate effectiveness of our present radiological report check flowchart enabling physicians to respond to significant unexpected findings (SUFs), by comparing the response periods from the examination date to the action date on untreated SUFs between the previous and present versions of our flowchart.MethodsIn the flowchart’s previous version used February–October 2019, SUFs, which were notified by email, were audited every month. The physician received a phone call and was asked to act on the untreated SUF. In the flowchart’s present version used from November 2019 to May 2020, SUFs were audited every 2 weeks. The physician and his/her chief were asked to return a written response to the untreated SUF. We evaluated the difference in the response periods between the previous and present versions of the flowchart.ResultsWith the previous flowchart’s use, untreated SUFs were 43 of 229 SUFs (18.8%) with the present flowchart untreated SUFs were 22 of 130 SUFs (16.9%). All SUFs in both periods were eventually responded. The present flowchart (median/range, 25/11–70 days) significantly had shorter response periods than the previous flowchart (70/16–290 days) (p < 0.0001).ConclusionThe present flowchart employing a shortened primary audit interval, a written response, and the department chief’s intervention, helped reduce the response periods.

BACKROUND: Not all patients with hepatocellular carcinoma (HCC) benefit from treatment with molecular targeted agents such as sorafenib. We investigated whether New-FP (fine-powder cisplatin and 5-fluorouracil), a hepatic arterial infusion chemotherapy regimen, is more favorable than sorafenib as an initial treatment for locally progressed HCC. METHODS: To avoid selection bias, we corrected the data from different facilities that did or did not perform New-FP therapy. In total, 1709 consecutive patients with HCC initially treated with New-FP or sorafenib; 1624 (New-FP, n = 644; sorafenib n = 980) were assessed. After propensity score matching (PSM), overall survival (OS) and prognostic factors were assessed (n = 344 each). Additionally, the patients were categorized into four groups: cohort-1 [(without macrovascular invasion (MVI) and extrahepatic spread (EHS)], cohort-2 (with MVI), cohort-3 (with EHS), and cohort-4 (with MVI and EHS) to clarify the efficacy of each treatment. RESULTS: New-FP prolonged OS than sorafenib after PSM (New-FP, 12 months; sorafenib, 7.9 months; p < 0.001). Sorafenib treatment, and severe MVI and EHS were poor prognostic factors. In the subgroup analyses, the OS was significantly longer the New-FP group in cohort-2. CONCLUSIONS: Local treatment using New-FP is a potentially superior initial treatment compared with sorafenib as a multidisciplinary treatment in locally progressed HCC without EHS.

Background To identify the genetic factors involved in the pathogenesis of primary biliary cirrhosis (PBC), we focused on the organic cation transporter 1 (OCT1/SLC22A1), which is closely associated with phosphatidylcholine synthesis in hepatocytes. Methods We selected four (rs683369, rs2282143, rs622342 and rs1443844) OCT - 1 single nucleotide polymorphisms (SNPs), and genotyped these SNPs using the TaqMan probe method in 275 Japanese PBC patients and 194 gender-matched, healthy volunteers as controls. Results The Chi-square test revealed that the rs683369 variant allele (G) was associated with insusceptibility to PBC development [ P  = 0.009, odds ratio (OR) 0.60, 95 % confidence interval (CI) 0.40–0.88] in an allele model, and that the rs683369 variant allele (G) was associated with jaundice-type progression in a minor allele dominant genotype model ( P  = 0.032, OR 3.10, 95 % CI 1.05–9.14). The OCT-1 rs2282143 variant (T) and rs622342 variant (C) were also associated with jaundice-type progression in a minor allele recessive genotype model ( P  = 0.0002, OR 10.58, 95 % CI 2.36–47.54, and P  = 0.006, OR 7.84, 95 % CI 1.39–44.36, respectively). Furthermore, the association of OCT - 1 rs683369 and rs622342 with susceptibility to jaundice-type progression was confirmed by a replication study with a distinct set of PBC patients who underwent liver transplantation. Conclusions The present study is the first report on the association of OCT - 1 genetic polymorphisms with the overall development and jaundice-type progression of PBC.

Telaprevir (TVR) is used for the treatment of chronic hepatitis C in a combination therapy with pegylated-interferon and ribavirin. Although renal dysfunction is one of the critical adverse outcomes of this treatment, little is known regarding the mechanism of its onset. The present study assessed the association of renal function with TVR dose and viral response. Hematological, biochemical, urinary and virological parameters of renal function were examined during the TVR-based triple therapy of patients infected with hepatitis C virus (HCV) genotype 1b. Serum creatinine levels were increased and the estimated glomerular filtration rate (eGFR) was decreased in every patient during TVR administration, but these values recovered to normal levels following cessation of TVR. Fractional excretion of sodium was <1% at days 3 and 7, appearing similar regardless of baseline renal function. Urinary β2-microglobulin levels were elevated and were significantly higher in patients with renal dysfunction, as compared with those not exhibiting renal dysfunction (P<0.05). The reduction in renal function was milder in patients treated with a reduced TVR dose, and these patients had a significantly lower risk of developing renal dysfunction (P<0.05). Using a multivariate analysis, TVR dose and eGFR at the initiation of treatment were identified as significant contributory factors in the development of renal dysfunction. Reduction in TVR dose did not lead to a significant increase in the viral kinetics of HCV or detrimental effects on the sustained viral response (SVR) rate. It is hypothesized that renal dysfunction during TVR treatment is caused by damage of the renal tubule, in addition to pre-renal dysfunction, and that reduction in TVR dose reduces the rate of renal dysfunction without causing a significant decrease in the SVR rate.

Background/Aim: Nutritional states of Japanese patients with liver cirrhosis have recently shown great diversity, some show protein energy malnutrition and others excessive nutrition and obesity. For there to be adequate guidance regarding dietary treatment, it is important that a patient's current nutritional state be clarified. Methods: We assessed nutritive intake in Japanese cirrhotic patients and determined their nutritional problems. Subjects were non-hospitalized patients with hepatitis C virus (HCV)-related cirrhosis in the compensated stage (n=47), chronic hepatitis C (n=46) or healthy volunteers (n=32). A brief self-administered diet history questionnaire was conducted with assistance from a registered dietitian. Results: We categorized patients with cirrhosis according to daily intake of energy and protein; 10.6% had an energy and protein intake within a normal range, 72.4% showed excessive intake, and 17.0% showed insufficient intake of energy or protein. In cirrhotic patients with diabetic complications, the intake levels of energy, proteins, fat and carbohydrates were significantly higher than in patients without diabetes. Moreover, cirrhotic patients had significantly higher intake levels of energy, protein and fat than did chronic hepatitis C patients and healthy individuals. In patients with HCV-related liver cirrhosis, insufficient intake of energy and protein was shown in some, while many, especially those with diabetes, showed excessive intake. Conclusion: For nutritive management of cirrhotic patients, the intake of various nutrients should be appropriately assessed and effective nutritional education systems established.

Background: Sorafenib, an oral multikinase inhibitor, was approved for the treatment of advanced hepatocellular carcinoma (HCC), but has not been adequately evaluated for safety and effectiveness in Japanese patients with advanced HCC. Aims: The purpose of this study was to prospectively assess the efficacy, safety, and risk factors for survival in patients with advanced HCC treated with sorafenib. Methods: Between May 2009 and December 2010, 96 Japanese patients with advanced HCC (76 male, 20 female, mean age: 70.4 years) were treated with sorafenib. Eighty-eight patients had Child-Pugh class A, and 8 patients had Child-Pugh class B liver cirrhosis. Barcelona Clinic Liver Cancer stage B and C were found in 64 and 32 patients, respectively. Results: Twelve patients demonstrated partial response to sorafenib therapy, 43 patients had stable disease, and 33 patients had progressive disease at the first radiologic assessment. The most frequent adverse events leading to discontinuation of sorafenib treatment were liver dysfunction (n = 8), hand-foot skin reaction (n = 7), and diarrhea (n = 4). The median survival time and time to progression were 11.6 and 3.2 months, respectively. By multivariate analysis, des-γ-carboxy prothrombin serum levels and duration of treatment were identified as independent risk factors for survival. Conclusions: This study showed that sorafenib was safe and useful in Japanese patients with advanced HCC. In addition, this study demonstrated that sorafenib should be administered as a long-term treatment for advanced HCC regardless of therapeutic effect and dosage.

We conducted an epidemiological study of 509 residents of H town, Fukuoka, Japan, to investigate the high mortality rate from liver disease. Antibodies to hepatitis C virus (HCV) (anti-HCV) were detected in 120 residents (23.6%); HCV RNA in 91 (17.9%), and hepatitis B surface antigen (HBsAg) in 13 (2.6%). Multivariate logistic regression analyses showed that presence of anti-HCV, male gender, and history of liver disease were associated with the presence of liver dysfunction, and that age of more than 40 years and a particular district were associated with the presence of anti-HCV. HCV RNA was more frequently detected in anti-HCV-positive men than women (41, or 85.4% versus 50, or 69.4%) (P < 0.05). The incidence of liver dysfunction was significantly higher in HCV RNA-positive men than women (32, or 66.7% versus 22, or 30.6%) (P < 0.05). These findings suggest that: (1) HCV was correlated with the high mortality rate from liver diseases, (2) there were district-related differences in the incidence of HCV, and (3) the lower frequency of elimination of HCV from men may explain why they showed a high mortality from liver disease.
