Although HIV infection has been reported to be a risk factor for OBI, the prevalence and clinical features of OBI in Japanese HIV infected patients have not been documented. This retrospective, single-center study was conducted to determine the prevalence and characteristic of OBI in Japanese antiretroviral therapy (ART) naïve HIV infected patients. OBI was defined as the presence of serum HBV DNA but without detectable HBsAg. Of the 147 ART naïve HIV infected patients, OBI was detected in 9 (6.1%) patients; 2 (4.3%) of 47 with both anti-HBs and anti-HBc positive, 6 (27.3%) of 22 with anti-HBc alone, and 1 (2.0%) of 50 with both anti-HBs and anti-HBc negative. The mean HBV DNA level was low at 28.7 ± 18.2 IU/mL. The proportion of OBI patients with anti-HBc alone was significantly higher than that of non-OBI patients (66.7% vs 14.5%, P = 0.001). In addition, the prevalence of AIDS (acquired immunodeficiency syndrome)-defining illnesses in the OBI group was significantly higher than in the non-OBI group (77.8% vs 35.5%, P = 0.001). No significant difference was found in the CD4 count or alanine aminotransferase levels of these two groups. This is the first study to reveal the prevalence and clinical features of OBI in Japanese HIV-infected patients. The persistence of anti-HBc alone and AIDS-defining illnesses were associated with the occurrence of OBI in these patients.. |

With the development of antiretroviral therapy (ART) for HIV, chronic HCV infection has become a major cause of liver disease and mortality for hemophiliac patients coinfected with HCV/HIV. Data is limited regarding the efficacy and safety of antiviral therapy with the HCV protease inhibitor telaprevir (TVR) in combination with pegylated interferon-α (PegIFN-α) and ribavirin (RBV) for hemophilia patients coinfected with HCV/HIV. We report a case of a Japanese patient with hemophilia and HCV/HIV coinfection who had partial response to prior to PegIFN-α and RBV therapy. This is the first published report of 24-week TVR-based triple therapy for a hemophilia patient coinfected with HCV/HIV. The patient had HCV genotype 1a infection with a high viral load. His single-nucleotide polymorphism of the interleukin 28B (rs8099917) gene was the TT major allele. He presented with undetectable HIV RNA and a high CD4(+) T cell counts by taking ART including tenofovir, emtricitabine and raltegravir. He was again treated for HCV with TVR plus PegIFN-α2b and RBV for the first 12 weeks, followed by the continuation of PegIFN-α2b and RBV for 12 additional weeks while continuing ART. He had rapid virological response and achieved sustained virological response with the 24-week treatment. No serious adverse events such as skin rash, severe anemia or exacerbated bleeding tendency were observed, only a mild headache. No dose adjustment was necessary when tenofovir and raltegravir were used in combined with TVR, and no HIV breakthrough was observed. TVR-based triple therapy with ART could can an effective treatment for hemophilia patients coinfected with HCV (genotype 1)/HIV regardless of prior response. TVR can be used in combination with tenofovir, emtricitabine and raltegravir for patients with hemophilia. Furthermore, patients with undetectable HCV RNA at week 4 could be successfully treated with a 24-week regimen.. |

METHODS: The data of 61 consecutive Japanese patients with chronic hepatitis B who underwent continuous lamivudine treatment for more than 24 mo and had a virological response were analyzed. Analysis of YMDD mutants was done by real-time polymerase chain reaction with LightCycler probe hybridization assay for up to 90 mo (mean, 50.8 mo; range, 24-90 mo). RESULTS: A mixed mutant-type (YMDD + tyrosine-isoleucine-asparatate-asparatate: YIDD or tyrosine-valine-asparatate-asparatate: YVDD) or a mutant-type (YIDD or YVDD) were found in 57.4% of 61 patients at 1 year, 78.7% of 61 patients at 2 years, 79.6% of 49 patients at 3 years, 70.5% of 34 patients at 4 years, 68.4% of 19 patients at 5 years, 57.1% of 14 patients at 6 years, and 33.3% of 6 patients at 7 years. Of the 61 patients, 56 (92%) had mixed mutant- or a mutant-type. Only 5 (8%) had no mutants at each observation point. Virological breakthrough was found in 26 (46.4%) of 56 patients with YMDD mutants, 20 of whom had a hepatitis flare-up: the remaining 30 (53.6%) had neither a virological breakthrough nor a flare-up. All 20 patients who developed a hepatitis flare-up had a biochemical and virological response after adefovir was added to the lamivudine treatment. CONCLUSION: Our results suggest that it is possible to continue lamivudine treatment, even after the emergence of YMDD mutants, up to the time that the patients develop a hepatitis flare-up.. |
