| 1 | Changes in lipid metabolism in chronic hepatitis C显示文摘AIM: To investigate the relationship between certain biochemical parameters of lipid metabolism in the serum and steatosis in the liver.METHODS: The grade of steatosis (0-3) and histological activity index (HAI, 0-18) in liver biopsy specimens were correlated with serum alanine aminotransferase (ALT), total cholesterol and triglyceride levels in 142 patients with chronic hepatitis C (CH-C), and 28 patients with non-alcoholic fatty liver disease (NAFLD) without hepatitis C virus (HCV) infection. The serum parameters were further correlated with 1 797 age and sex matched control patients without any liver diseases.RESULTS: Steatosis was detected in 90 out of 142 specimens (63%) with CH-C. The ALT levels correlated with the grade of steatosis, both in patients with CH-C and NAFLD (P<0.01). Inserting the score values of steatosis as part of the HAI, correlation with the ALT level (P<0.00001) was found. The triglyceride and cholesterol levels were significantly lower in patients with CH-C (with and without steatosis), compared to the NAFLD group and to the virus-free control groups.CONCLUSION: Our study confirms the importance of liver steatosis in CH-C which correlates with lower lipid levels in the sera. Inclusion of the score of steatosis into HAI, in case of CH-C might reflect the alterations in the liver tissue more precisely, while correlating with the ALT enzyme elevation. | Katalin Jármay Gizella Karácsony András Nagy Zsuzsa Schaff | 2005 | World Journal of Gastroenterology2005，11，41： | 22 |
| 2 | Elevated miR-33a and miR-224 in steatotic chronic hepatitis Cliver biopsies显示文摘AIM:To assess the expression of selected microRNAs(miRNA) in hepatitis C,steatotic hepatitis C,noninfected steatotic and normal liver tissues.METHODS:The relative expression levels of miR-21,miR-33 a,miR-96,miR-122,miR-125 b,miR-221 and miR-224 were determined in 76 RNA samples isolated from 18 non-steatotic and 28 steatotic chronic hepatitis C(CHC and CHC-Steatosis,respectively) cases,18 non-infected,steatotic liver biopsies of metabolic origin(Steatosis) and 12 normal formalin-fixed paraffin-embedded liver tissues using TaqMan MicroRNA Assays.All CHC biopsy samples were obtained prior to initiating therapy.Patients' serum biochemical values,which included glucose,triglyceride,cholesterol,alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl-transferase(GGT),alkaline phosphatase(AP),were obtained and correlated with relative miRNA expression.RESULTS:When compared with control non-infected liver samples,miR-122 and miR-221 levels were reduced in CHC-Steatosis(P < 0.03) and in CHC,CHCSteatosis and Steatosis(P < 0.01).Alternatively,the expression of miR-33 a and miR-224 were elevated in CHC-Steatosis and Steatosis in comparison to control tissue(P < 0.01).The levels of miR-33 a and miR-224 in CHC-Steatosis(P < 0.02) and miR-224 in Steatosis(P < 0.001) were increased in comparison to CHC samples.By contrast,the expression of miR-21 did not differ statistically between diseased and normal liver samples.Levels of miR-33 a correlated negatively with serum AST and AP levels in Steatosis as well as with necroinflammatory grade in CHC,whereas miR-21 correlated positively with AST in Steatosis and displayed negative correlation with triglyceride level in CHC-Steatosis.In contrast,miRNA levels were not correlated with ALT,GGT,cholesterol levels or fibrosis stage.CONCLUSION:Differences in miRNA expression were observed between CHC and steatotic CHC,CHC and steatotic liver,but not between steatotic CHC and steatotic liver of metabolic origin. | Gabor Lendvai Katalin Jármay Gizella Karácsony Tünde Halász Ilona Kovalszky Kornélia Baghy Tibor Wittmann Zsuzsa Schaff András Kiss | 2014 | World Journal of Gastroenterology2014，20，41： | 2 |
