Circulating ICAM-1 levels were not elevated in low-flux membranes and most of the high-flux HD membranes, except for one high-flux polysulfone membrane. cVCAM-1 levels were significantly elevated both in low- and high-flux dialysis membranes, whereas cE-selectin was not increased. cICAM-1 levels were not different before and after hemodialysis in the entire study group. In contrast, cVCAM-1 and cE-selectin levels increased significantly during HD in the entire study group (both p<0.001)
