| 1 | Association between endotoxemia and histological features of nonalcoholic fatty liver disease显示文摘AIM To assess whether surrogate biomarkers of endotoxemia were correlated with the histological features ofnonalcoholic fatty liver disease(NAFLD).METHODS One hundred twenty-six NAFLD patients who had undergone percutaneous liver biopsy were enrolled. Serum lipopolysaccharide(LPS)-binding protein(LBP) and anti-endotoxin core immunoglobulin G(Endo Cab Ig G) antibody concentrations at the time of liver biopsy were measured using the enzyme-linked immunosorbent assays to examine for relationships between biomarker levels and histological scores. RESULTS Serum LBP concentration was significantly increased in nonalcoholic steatohepatitis(NASH) patients as compared with nonalcoholic fatty liver(NAFL) subjects and was correlated with steatosis(r = 0.38, P < 0.0001) and ballooning scores(r = 0.23, P = 0.01), but not with the severity of lobular inflammation or fibrosis. Multivariate linear regression analysis revealed that LBP was associated with steatosis score and circulating C-reactive protein, aspartate aminotransferase, and fibrinogen levels. Serum Endo Cab Ig G concentration was comparable between NASH and NAFL patients. No meaningful correlations were detected between Endo Cab Ig G and histological findings. CONCLUSION LBP/Endo Cab Ig G were not correlated with lobular inflammation or fibrosis. More accurate LPS biomarkers are required to stringently assess the contribution of endotoxemia to conventional NASH. | Hiroyuki Kitabatake Naoki Tanaka Naoyuki Fujimori Michiharu Komatsu Ayaka Okubo Kyogo Kakegawa Takefumi Kimura Ayumi Sugiura Tomoo Yamazaki Soichiro Shibata Yuki Ichikawa Satoru Joshita Takeji Umemura Akihiro Matsumoto Masayoshi Koinuma Kenji Sano Toshifumi Aoyama Eiji Tanaka | 2017 | World Journal of Gastroenterology2017，23，4： | 5 |
| 2 | Mutations of pre-core and basal core promoter before and after hepatitis B e antigen seroconversion显示文摘AIM: To investigate the role of pre-core and basal core promoter(BCP) mutations before and after hepatitis Be antigen(HBe Ag) seroconversion.METHODS: The proportion of pre-core(G1896A) and basal core promoter(A1762T and G1764A) mutant viruses and serum levels of hepatitis B virus(HBV) DNA, hepatitis B surface antigen(HBs Ag), and HB core-related antigen were analyzed in chronic hepatitis B patients before and after HBe Ag seroconversion(n = 25), in those who were persistently HBe Ag positive(n = 18), and in those who were persistently anti-HBe positive(n = 43). All patients were infected with HBV genotype C and were followed for a median of 9 years.RESULTS: Although the pre-core mutant became predominant(24% to 65%, P = 0.022) in the HBe Ag seroconversion group during follow-up, the proportion of the basal core promoter mutation did not change. Median HBV viral markers were significantly higher in patients without the mutations in an HBe Ag positive status(HBV DNA: P = 0.003; HBs Ag: P < 0.001; HB core-related antigen: P = 0.001). In contrast, HBV DNA(P = 0.012) and HBs Ag(P = 0.041) levels were significantly higher in patients with the pre-core mutation in an anti-HBe positive status.CONCLUSION: There is an opposite association of the pre-core mutation with viral load before and after HBe Ag seroconversion in patients with HBV infection. | Nozomi Kamijo Akihiro Matsumoto Takeji Umemura Soichiro Shibata Yuki Ichikawa Takefumi Kimura Michiharu Komatsu Eiji Tanaka | 2015 | World Journal of Gastroenterology2015，21，2： | 4 |
| 3 | Systemic hemodynamics in advanced cirrhosis: Concerns during perioperative period of liver transplantation显示文摘Advanced liver cirrhosis is usually accompanied by portal hypertension. Long-term portal hypertension results in various vascular alterations. The systemic hemodynamic state in patients with cirrhosis is termed a hyperdynamic state. This peculiar hemodynamic state is characterized by an expanded blood volume, high cardiac output, and low total peripheral resistance. Vascular alterations do not disappear even long after liver transplantation(LT), and recipients with cirrhosis exhibit a persistent systemic hyperdynamic state even after LT. Stability of optimal systemic hemodynamics is indispensable for adequate portal venous flow(PVF) and successful LT, and reliable parameters for optimal systemic hemodynamics and adequate PVF are required. Even a subtle disorder in systemic hemodynamics is precisely indicated by the balance between cardiac output and blood volume. The indocyanine green(ICG) kinetics reflect the patient's functional hepatocytes and effective PVF, and PVF is a major determinant of the ICG elimination constant(kICG) in the well-preserved allograft. The kICG value is useful to set the optimal PVF during living-donor LT and to evaluate adequate PVF after LT. Perioperative management has a large influence on the postoperative course and outcome; therefore, key points and unexpected pitfalls for intensive management are herein summarized. Transplant physicians should fully understand the peculiar systemic hemodynamic behavior in LT recipients with cirrhosis and recognize the critical importance of PVF after LT. | Tomohide Hori Yasuhiro Ogura Yasuharu Onishi Hideya Kamei Nobuhiko Kurata Motoshi Kainuma Hideo Takahashi Shogo Suzuki Takashi Ichikawa Shoko Mizuno Tadashi Aoyama Yuki Ishida Takahiro Hirai Tomoko Hayashi Kazuko Hasegawa Hiromu Takeichi Atsunobu Ota Yasuhiro Kodera Hiroyuki Sugimoto Taku Iida Shintaro Yagi Kentaro Taniguchi Shinji Uemoto | 2016 | World Journal of Hepatology2016，8，25： | 3 |
