Activation of immunocompetent cells in the peritoneum of patients treated with CAPD

Activation of immunocompetent cells in the peritoneum of patients treated with CAPD. Chemiluminescence and flow cytometry, employing a number of monoclonal antibodies, was used to investigate activation of immunocompetent cells in the blood and peritoneum of patients treated with CAPD. Increased expression of HLA-DR and RFD7, both markers of macrophage maturation, was observed on peritoneal macrophages, 78% and 33.5% cells positive, when compared to blood monocytes, which were 46% and 5.3%, respectively (P
