Abstract

Hemodialysis (HD) patients can develop acute reactions during treatment as well as increased long-term susceptibility to infections and malignancies. Abnormalities in leukocyte adhesion may contribute to these processes. Recently, serum levels of soluble adhesion molecules have been detected in circulating blood of normal subjects and in patients with chronic renal failure. We studied the effects of a single dialysis session with new cuprophane membrane on the soluble (s) form of intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), two adhesion molecules with a variety of immunologic roles. Significant elevations in both sICAM-1 (523 ± 61 v 304 ± 45 [SEM] ng/mL, P < 0.05) end sVCAM-1 (2,055 ± 270 v 1,189 ± 149 ng/mL, P < 0.05) were observed in HD patients at baseline compared with controls. Both sICAM-1 and sVCAM-1 levels decreased after a 3-hour HD session (P < 0.001). Early in HD, sICAM-1 levels, though lower then predialysis, were elevated in the exit line of the dialyzer compared with entrance (339 ± 64 v 259 ± 53 ng/mL, P < 0.001), whereas sVCAM-1 was decreased on the exit line compared with entrance (639 ± 90 v 932 ± 92 ng/mL, P < 0.001). Because ICAM-1 and VCAM-1 are important for many leukocyte functions, alterations in serum levels of sICAM-1 and sVCAM-1 may play a role in the immunologic consequences of uremia and HD treatment.
