    Abstract Background. The study aims to analyze in detail the incidence, mortality using the standardized incidence ratio (SIR), and standardized mortality ratio (SMR) of hepatocellular carcinoma (HCC) in primary biliary cirrhosis (PBC), because no large case studies have focused on the detailed statistical analysis of them in Asia. Methods. The study cohorts were consecutively diagnosed at Gunma University and its affiliated hospitals. Age- or sex-specific annual cancer incidence and deaths were obtained from Japanese Cancer Registry and Death Registry as a reference for the comparison of SIR or SMR of HCC. Moreover, univariate analyses and multivariate analyses were performed to clarify predictive factors for the incidence of HCC. Results. The overall 179 patients were followed up for a median of 97 months. HCC had developed in 13 cases. SIR for HCC was 11.6 (95% confidence interval (CI), 6.2-19.8) and SMR for HCC was 11.2 (95% CI, 5.4-20.6) in overall patients. The serum albumin levels were a predictive factor for the incidence of HCC in overall patients. Conclusions. The incidence and mortality of HCC in PBC patients were significantly higher than those in Japanese general population. PBC patients with low serum albumin levels were populations at high risk for HCC.

    Abstract Objectives: The aim of this study was to assess the long-term prognosis, efficacy, and safety of combination therapy using ursodeoxycholic acid (UDCA) and bezafibrate (BF) for primary biliary cirrhosis (PBC) patients exhibiting dyslipidemia.
    Methods: We performed a prospective, randomized, controlled, multicenter study to compare the long-term clinical results between combination therapy and UDCA monotherapy for patients refractory to UDCA monotherapy. Twenty-seven consecutive PBC patients were enrolled.
    Results: The median treatment period in the UDCA and UDCA+BF groups was 107 and 110 months, respectively. The serum alkaline phosphatase (ALP) levels and the Mayo risk score in the combination therapy group (mean 290 IU/l and 0.91, respectively) were significantly lower than those in the UDCA monotherapy group (mean 461 IU/l and 1.42, respectively) at 8 years after the beginning of the study (P<0.05). The serum creatinine levels in the combination therapy group (mean 0.94 mg/dl) were significantly higher than those in the UDCA monotherapy group (mean 0.56 mg/dl) at 8 years after the beginning of the study (P<0.05). However, the survival rate was not significantly different between the groups. We observed dose reduction or discontinuation of the administration of BF, but not UDCA, due to renal dysfunction or muscle pain.
    Conclusions: Long-term combination therapy significantly improved the serum ALP levels and the Mayo risk score. However, the survival rate was not significantly different between the groups. In addition, long-term combination therapy significantly increased the serum creatinine levels. We should pay close attention to adverse events during this long-term combination therapy.

    Abstract Hepatitis C virus (HCV) infection is common in dialysis patients worldwide and nosocomial HCV spread within dialysis facilities continues to develop. Combination therapy with daclatasvir and asunaprevir (DCV/ASV) that has proven efficacy for dialysis patients infected with genotype 1b HCV (HCV/1b) has several concerns in Japan. The recently available combination therapy with ombitasvir, paritaprevir, and ritonavir (OBV/PTV/r) is not contraindicated in patients with chronic renal failure and has more safety profile and shorter treatment period than that with DCV/ASV. We evaluated the effects of combination therapy with OBV/PTV/r in four dialysis patients infected with HCV/1b, who were eligible for our study. On-treatment assessments included standard laboratory testing, serum HCV RNA and symptom-directed physical examinations. Three patients had a sustained virological response at 12 weeks after treatment, but one remaining patient had viral breakthrough. Notably, the patient with viral breakthrough had been coinfected with HCV/1b and HCV/2b; namely, HCV/2b with resistance-associated variations was not eradicated by the combination therapy. Among the three patients responsive to the combination therapy, one patient complained of appetite loss and itching, while in another patient the therapy was discontinued due to itching, exacerbation of wamble, and a falling tendency probably due to interaction with valsartan. These AEs were ameliorated or disappeared after the completion of the therapy. The significance of our study is persuasive virological evaluation associated to the combination therapy and reasonable interpretation of AEs. In conclusion, combination therapy with OBV/PTV/r may have promise as an efficacious therapy, but caution regarding AEs should be practiced.

    Abstract A small-cell carcinoma of the extrahepatic bile duct in a 69-year-old woman is herein reported. A tumor measuring approximately 3 cm in diameter was located at the confluence of the common bile duct, cystic duct, and common hepatic duct. Histopathologically, the tumor was small-cell neuroendocrine carcinoma without any gland formation or differentiation to squamous cell carcinoma. Tumor cells were immunoreactive for epithelial markers such as epithelial membrane antigen and cytokeratin and for the neuroendocrine markers such as neuron-specific enolase, chromogranin A, and synaptophysin. Although the carcinomas in more than half of the reported cases have been reported to be associated with well-to-moderately differentiated squamous or glandular components, seven cases, including our case, showed the carcinomas without squamous or glandular components. According to the review of 16 previously reported cases and our case of small-cell carcinoma of the extrahepatic bile ducts, there is no significant difference in the clinicopathological findings, namely, age, sex, site of carcinoma, and prognosis between the cases with or without squamous or glandular components. No CD34-positive multipotent adult progenitor cells, which might be the origin of the small-cell carcinoma, were detected in the bile duct epithelium in our case.

    Abstract Background: Primary biliary cirrhosis (PBC) is regarded as an autoimmune liver disease and familial clustering of PBC could represent some genetic predisposition to the disease.
    Aims: To elucidate the genetic background of PBC by investigating familial cases of PBC.
    Methods: Familial cases were picked out from 171 PBC patients who enrolled in this study. We analyzed them and their family members, and compared them clinically and immunogenetically to non-familial cases.
    Results: Out of 171 PBC patients, ten (5.8%) were identified as familial PBC in five families. The clinical features of familial PBC were almost comparable to those of non-familial PBC. The distribution of human leukocyte antigens (HLA)-A, -B and -DR in familial PBC showed no specificity. Two new PBC patients were identified in one family in addition to the two originally enrolled PBC patients, resulting in four patients with PBC within the same family. The two new PBC patients had an identical HLA haplotype. On the other hand, one HLA-identical sister of a PBC patient in another family did not develop PBC.
    Conclusions: Primary biliary cirrhosis can exhibit familial clustering without any HLA predisposition, however, a survey of families for PBC could be useful for identifying new patients with PBC in the asymptomatic stage for earlier diagnosis and treatment.

    Abstract Background and aims: The Japan Society for Dialysis Therapy established "Guidelines for the Treatment of Hepatitis C Virus Infection in Dialysis Patients." We evaluated the status of HCV infection and the treatment of hemodialysis patients in Gunma prefecture.
    Methods: Questionnaires concerning the infection rate, recognition of the guidelines, and treatment status were sent to all 64 hospitals/clinics that had hemodialysis systems in Gunma prefecture. The hepatitis C virus-infected hemodialysis patients who received pegylated interferon (peg-IFN) were analyzed at Gunma University Hospital.
    Results: The positive rate for hepatitis C virus antibody was 256/2582 hemodialysis patients (9.9%). The positive rate varied between institutions (range 0-40.0%; median 9.0%). All institutes recognized the establishment of the guidelines. Conventional or peg-IFN treatment was being given at 37.5% of the institutions. The other 62.5% institutions answered that they intended to provide the treatment in the future if collaboration with a hepatologist could be arranged. The most common answers regarding the indication for IFN treatment were as follows: few complications, under 60 years of age, more than 10 years of survival expected on hemodialysis. Eighteen patients received peg-IFN treatment. The sustained virological response rate of all patients was 33.3%, 0% in 1b/high viral titer, 50% in genotype 2, and 100% in genotype 2/low viral titer. The sustained virological response rate was worse in the patients with 1b/high viral load and diabetic nephropathy (P < 0.05).
    Conclusions: Recognition of the publication of the guidelines was high. However, the number of patients treated with peg-IFN was still low. Further enlightenment and cooperation between hemodialysis teams and hepatologists are therefore needed.
