In conclusion, tenofovir DF therapy in HBV-infected adolescents was well tolerated and highly effective at suppressing HBV DNA and normalizing ALT values in both treatment-naïve patients and those with prior exposure to oral HBV therapy. No resistance to tenofovir DF was observed through week 72, and lamivudine-associated mutations at baseline appeared to have no effect on virologic response. Tenofovir DF is, therefore, a valuable treatment

option for the management of CHB in adolescents. We thank Amy Lindsay, Ph.D., and Evelyn Albu, Ph.D., of Percolation Communications LLC for providing editorial assistance. “
“Aim:  Although hepatocellular carcinoma (HCC)-specific serum tumor markers, α-fetoprotein (AFP) and des-γ-carboxy prothrombin (DCP), are used in the screening for HCC, their utility in pre-transplantation evaluation is not well established. This study selleck kinase inhibitor aimed to evaluate the accuracy of AFP and DCP measurement for the diagnosis of HCC in liver transplant candidates. Methods:  A total of 315 consecutive adult patients (174 men and 141 women, see more mean age 52 years), who

were to receive liver transplantation for end-stage liver diseases, were enrolled. The pre-transplant levels of AFP and DCP were compared with the histopathology of explanted liver. Results:  Hepatocellular carcinoma was present in the explanted liver of 106 recipients PJ34 HCl (median number of nodules 2, mean diameter 2.5 cm). The area under receiver operating characteristic curve for the diagnosis

of HCC was 0.83 (95% confidence interval, 0.78–0.88) for AFP and 0.47 (0.41–0.54) for DCP. With the cut-off value of 100 mAU/mL, 20/106 (18.9%) patients with HCC and 54/194 (27.8%) patients without HCC were positive for DCP. DCP positivity was associated with vascular invasion, tumor differentiation and size among patients with HCC, which was associated with albumin level among patients without HCC. Vitamin K was administered prior to transplantation to 20 patients who were positive for DCP (two with and 18 without HCC), resulting in a decrease in DCP levels in 19 of them. Conclusions:  Serum DCP levels may be raised in end-stage liver disease patients without HCC, and cannot be used as a reliable marker for HCC among liver transplant candidates. “
“The serum alanine aminotransferase (ALT) assay is the most common laboratory test for the detection of liver disease.1 Because ALT is continuously distributed in populations and might be influenced not only by liver disease, but also various medical conditions unrelated to liver disease, and demographic determinants (age, sex, and body mass index), the cut-off serum ALT value that discriminates between healthy and diseased livers has not been clearly defined.
