| 1 | Endotoxin receptor CD14 gene variants and histological features in chronic HCV infection显示文摘AIM:To analyze the correlation between CD14 rs2569190/C-159T single nucleotide polymorphism (SNP) and disease progression in chronic hepatitis C.METHODS: Liver biopsy specimens from a total of 137 and 349 patients with chronic hepatitis C were separately evaluated with respect to necroinflammatory activity (grading) and architectural changes (staging). In one group, further histological lesions characteristic for hepatitis C, hepatitis C virus subtypes, and biochemical parameters of liver disease were also investigated. Samples of genomic DNA were genotyped for the respective SNP by 5'-nuclease assays using fluorescent dye-labeled allele-specif ic probes.RESULTS: Genotype distribution did not deviate from the Hardy-Weinberg equilibrium. In the first group, patients homozygous for the variant allele T were found to be younger than C allele carriers (39.6±12.5 vs 45.7±11.5, P=0.008). Among the histological lesions studied, portal lymphoid aggregates were more frequently observed among TT homozygotes than among C carriers (21/37 vs 32/100, P=0.008). The presence of portal lymphoid aggregates was closely correlated with hepatic inflammation (P=0.003) and with bile duct damage (P<0.001). The degree of fibrosis, in contrast, was not found to be related to the CD14 gene C-159T polymorphism.CONCLUSION: The data suggest a possible relationship between CD14 C-159T polymorphism and the formation of portal lymphoid aggregates, but not liver fibrosis progression in chronic hepatitis C. | Eva Askar Giuliano Ramadori Sabine Mihm | 2009 | World Journal of Gastroenterology2009，15，31： | 2 |
