RESUMEN

BACKGROUND: Sofosbuvir plus ribavirin (RBV) therapy showed higher sustained virological response at 12 weeks after treatment (SVR12) than pegylated interferon (peg-IFN) plus RBV; however, liver function, fibrosis, and hepatocellular carcinoma markers have not been assessed so far. SUMMARY: Patients (n = 21) receiving Sofosbuvir plus RBV and those (n = 24) receiving peg-IFN plus RBV were enrolled in this study. Changes in alanine aminotransferase (ALT) and α-fetoprotein (AFP) levels, platelet (PLT) counts, FIB-4, and aspartate aminotransferase-to-platelet ratio index (APRI) in both groups were assessed in patients achieving SVR12. Also, fibrosis regression was assessed using pathophysiological biomarkers, such as hyaluronic acid, bone morphogenetic protein 7 (BMP-7), and connective tissue growth factor (CTGF) in the Sofosbuvir plus RBV group. In both groups, while the reduction in ALT levels was significant that of AFP was not. Compared with the baseline, although serum PLT count at the end of treatment (EOT) was significantly higher in the Sofosbuvir plus RBV group, it was significantly lower in the peg-IFN plus RBV group. Although a significant decline in fibrosis markers such as FIB-4 and APRI was observed between the baseline and at EOT in the Sofosbuvir plus RBV group, no significant change of these markers was observed in the peg-IFN plus RBV group. Moreover, BMP-7 and CTGF were significantly lower at EOT than the baseline in the Sofosbuvir plus RBV group. Key Message: The treatment with Sofosbuvir plus RBV results in not only a higher SVR, but also improves the liver function and the degree of fibrosis.

RESUMEN

OBJECTIVES: The efficacy of the all-oral administration of daclatasvir and asunaprevir for 24 weeks was compared with that of telaprevir for 12 weeks plus pegylated interferon and ribavirin (PEG-IFN/RBV) for 24 weeks, and that of simeprevir for 12 weeks plus PEG-IFN/RBV for 24 weeks, with a focus on the prevention of occurrence and recurrence of hepatocellular carcinoma (HCC). The levels of alanine aminotransferase (ALT) and α-fetoprotein (AFP) as suppressive markers of HCC were also measured. METHODS: Patients received daclatasvir and asunaprevir (n = 17), simeprevir plus PEG-IFN/RBV (n = 15) and telaprevir plus PEG-IFN/RBV (n = 25). Sustained virological response (SVR) and the mean change in the level of serum ALT, AFP and platelet (PLT) count were compared among the three groups. RESULTS: No difference in SVR was observed in patients given daclatasvir with asunaprevir (SVR4), telaprevir plus PEG-IFN/RBV or simeprevir plus PEG-IFN/RBV (SVR24). Also, no significant difference was observed in the mean change of serum ALT, AFP or PLT count among the three groups. CONCLUSION: The preventive effect of the IFN-free, all-oral regimen of daclatasvir and asunaprevir was observed with a focus on the occurrence and recurrence of HCC, as was IFN-based treatment with telaprevir or simeprevir plus PEG-IFN/RBV.

RESUMEN

At present, for adults with chronic hepatitis B virus (HBV) infection, two new analogues, entecavir (ETV) and tenofovir, are recommended as the first-line therapy by the EASL (European Association for the Study of the Liver), AASLD (American Association for the Study of Liver Diseases), and APASL (Asian Pacific Association for the Study of the Liver) guidelines. The use of pegylated interferon-α (PEG IFN-α) is recommended as the first-line therapy instead of standard IFN-α according to the above 3 guidelines. In this paper, the aim was to assess: (1) the long-term efficacy and safety as well as the resistance to ETV and tenofovir disoproxil fumarate (TDF); (2) the efficacy of PEG IFN-α; (3) the role of combination therapy with IFN plus two analogues, such as lamivudine and ETV; (4) the efficacy and safety of two analogues with cirrhosis, and (5) suppression of hepatocellular carcinoma (HCC) by ETV and IFN treatment. The results are as follows: (1) both ETV and TDF showed long-term efficacy and safety; (2) PEG IFN-α resulted in a greater decline in HBV DNA levels and a higher rate of HBeAg seroconversion; (3) combination therapy with IFN plus two analogues did not elevate the rate of sustained responses; (4) both ETV and TDF showed efficacy and safety with cirrhosis (ETV especially displayed efficacy and safety with decompensated cirrhosis), and (5) suppression of HCC was observed by ETV and IFN.

RESUMEN

BACKGROUND/AIMS: Insulin resistance (IR) has been reported to be an independent predictor of treatment outcome in chronic hepatitis C patients. METHODS: We analyzed the relationship between IR and the outcome of pegylated interferon and ribavirin (PEG-IFN/RBV) therapy, taking into account host factors of body mass index and histological index, such as rate of fatty change and fibrosis. Japanese patients (n = 30; 19 men and 11 women; median age 60.0 ± 8.7 years) with chronic hepatitis C-1b with a high viral load were treated with PEG-IFN-α2b/RBV for 48 weeks. RESULTS: Sustained virological response (SVR) was seen in 60% (18/30) and non-SVR in 40% (12/30). HOMA-IR (homeostasis model of assessment-insulin resistance index) at the start and at 24 weeks of treatment showed no statistical difference between SVR and non-SVR. Correlation was observed between HOMA-IR and body mass index (r = 0.45, p = 0.013). Among 20 patients, steatosis and fibrosis were assessed by biopsy. Correlation was observed between HOMA-IR and steatosis (r = 0.57, p = 0.0093), whereas no correlation was observed between HOMA-IR and fibrosis. CONCLUSION: A larger prospective study is needed to clarify the role of IR in the outcome of PEG-IFN/RBV combination therapy and hepatic fibrosis in Japanese patients.

RESUMEN

BACKGROUND: Metastasis occurs as a late event in the natural history of hepatocellular carcinoma (HCC), and most patients die of liver failure attributed to the tumor supplanting the liver. Conversely, the brain is a less common metastatic site. CASE SUMMARY: We describe a rare case of hepatitis C virus-related multiple HCC metastasizing to the cavernous sinus, Meckel's cave, and the petrous bone involving multiple cranial nerves in an 82-year-old woman. At admission imaging studies including Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (MRI) revealed multiple HCC nodules in both right and left lobes. Ultrasound guided biopsy of the left lobe revealed moderately differentiated HCC. Molecular targeted therapy with Lenvatinib (8 mg/d for 94 d, per os) and Ramucirumab (340 mg/d and 320 mg/d, two times by intravenous injection) were administered for 4 mo, resulting in progression of the disease. Three months after the start of molecular target therapy, the patient presented with symptoms of hyperalgesia of the right face and limited abduction of the right eye, indicating disturbances in the right trigeminal and abducens nerves. Brain MRI disclosed a mass involving the cavernous sinus, Meckel's cave and the petrous bone. Contrast-enhanced MRI with gadolinium-chelated contrast medium revealed a well-defined mass with abnormal enhancement around the right cavernous sinus and the right Meckel's cave. CONCLUSION: The diagnosis of metastatic HCC to the cavernous sinus, Meckel's cave, and the petrous bone was made based on neurological findings and imaging studies including MRI, but not on histological examinations. Further studies may provide insights into various methods for diagnosing HCC metastasizing to the craniospinal area.

RESUMEN

PURPOSE: Zinc has been reported to ameliorate hematologic side effects and improve liver function. In addition to its various effects, zinc supplementation in chronic hepatitis C patients with genotype 1b of high viral load enhanced the response to interferon (IFN) monotherapy. This study was aimed at clarifying whether zinc could improve hematologic side effects, improve liver function, and enhance the response to therapy in patients with chronic hepatitis C treated with pegylated-interferon (PEG-IFN) plus ribavirin (RBV). METHODS: The 32 patients enrolled in the study were randomly divided into two groups: a PEG-IFN-alpha2b plus RBV with zinc group (PEG/RBV + zinc, n = 16) and a PEG-IFN-alpha2b plus RBV group (PEG/RBV, n = 16). HCV-RNA, serum zinc, ALT, white blood cell, red blood cell, platelet, and hemoglobin (Hb) levels were examined. RESULTS: Serum zinc levels were significantly higher in the PEG/RBV with zinc group than in the PEG/RBV without zinc group at 4, 8, and 12 weeks. No significant differences were observed in the clearance of HCV-RNA between the two groups. The outcome of the treatment was similar; results of laboratory examinations including ALT before, during, and after therapy revealed no significant differences between the two groups at any point in all items except serum zinc levels. A sustained virological response rate was observed in 50.0% in the PEG/RBV with zinc group and 43.8% in the PEG/RBV without zinc group, with no significant difference between the two groups. CONCLUSIONS: The study demonstrated no evidence that zinc ameliorates hematologic side effects, improves liver function, and enhances the response to the therapy in chronic hepatitis C receiving PEG-IFN-alpha2b plus RBV.

RESUMEN

SM-11355, cis-[((1R, 2R)-1, 2-cyclohexanediamine-N, N')bis(myristato)]platinum(II), suspended in Lipiodol (SM-11355/Lipiodol) showed cytotoxic activity in hepatic tumor models in vivo and tumor cell lines in vitro. SM-11355/Lipiodol demonstrated selective retention in tumor tissue in vivo and high accumulation in tumor cells in vitro. This study was aimed to clarify the relation between the cytotoxicity of SM-11355/Lipiodol and intracellular platinum content. The cytotoxic activities were estimated by using WST-1 reagent. Intracellular platinum content and platinum-DNA adduct were estimated following exposure with SM-11355/Lipiodol when methionine was added. Methionine clearly inhibited the cytotoxic activities of SM-11355/Lipiodol. Moreover, intracellular platinum content and platinum-DNA adduct following exposure of SM-11355/Lipiodol decreased with increases in methionine concentration. The characteristic release of SM-11355/Lipiodol was not affected by addition of methionine. The present results suggested that one of platinum compounds exposed to cells following SM-11355/Lipiodol treatment is very similar in cytotoxic mechanism to cisplatin.
