In scleroderma endothelial cell damage plays an early and pivotal role in the pathogenesis of sclerotic lesions. In our study we determined whether or not plasma from 11 consecutive patients with scleroderma contained a subset of larger than normal (supranormal) multimers of von Willebrand factor which are potent inducers of platelet aggregation and adhesion. Supranormal multimers were found in all patients, but in none of the normal controls. Supranormal multimers may contribute to the pathogenesis of systemic sclerosis by inducing platelet aggregation and enhancing adhesion to subendothelium.
