The adhesion molecules ICAM-1, VCAM-1 and E-Selectin are regulated by proinflammatory cytokines and play an important role in the binding and activation of leukocytes in inflammatory diseases. This study measured the serum concentrations of circulating adhesion molecules (cICAM-1, cVCAM-1, cE-Selectin) by sandwich ELISA in systemic vasculitis with renal involvement (Wegener's granulomatosis WG, n = 25; systemic lupus erythematosus SLE, n = 50) in comparison to chronic glomerulonephritis (n = 10), stable renal allograft function and end-stage renal disease (CAPD/hemodialysis, each n = 10). Both cICAM-1 and cVCAM-1 levels, but not cE-Selectin, were significantly increased (p < 0.001) in active WG compared to healthy controls. cICAM-1, not cVCAM-1 differed significantly between active and inactive WG. Only cVCAM-1 was significantly elevated in active/inactive SLE (p < 0.01). WG with rapidly progressive glomerulonephritis had significantly raised levels of cICAM-1 and cVCAM-1, but not cE-Selectin, compared to controls (p < 0.005). In lupus nephritis only cVCAM-1 was significantly elevated (p < 0.01). cICAM-1 and cVCAM-1 levels were significantly raised in WG patients, that were hemodialysed and in patients with hemodialysis because of different reasons when compared to controls. However, cVCAM-1 but not cICAM-1 was significantly higher in WG with HD than without HD. Patients with chronic glomerulonephritis, renal allografts or CAPD also had significantly raised cVCAM-1 concentrations. These data suggest, that levels of circulating adhesion molecules might reflect different pathophysiologic processes in systemic vasculitides and endothelial/immune activation in non-inflammatory renal diseases.
