| pubmed-article:1828820 | pubmed:abstractText | To evaluate the expression of hepatocyte HLA Class I and II antigens and the infiltration of CD8-positive lymphocytes in patients with chronic hepatitis, cells obtained by the technique of fine-needle aspiration were compared with those obtained by percutaneous liver biopsy. In general, correlation between cytological and histological specimens of HLA Class I and Class II antigen expression and CD8 lymphocyte infiltration was excellent when comparing results of the core biopsy expressed semiquantitatively, and results from fine-needle aspiration quantitatively as percentage of cells stained. Although the major potential of multiple fine-needle aspiration sampling probably will be in the surveillance of patients who have received orthotopic liver transplants, the results of this study indicate that fine-needle aspiration can provide a useful technique for following antigen expression and inflammatory changes in studies in which frequent periodic samples may be necessary to monitor efficacy or toxicity of treatment regimens. | lld:pubmed |
