[t-PA and PAI in patients with Raynaud's syndrome in treatment with a stable prostacyclin analog]

Abstract

An study was made in order to determinate the relationship between the restoration of the local fibrinolytic activity and the clinical signs in patients with a Raynaud's phenomenon. It is known that local fibrinolytic activity is a system influenced by changes into its components produced by exogenous and endogenous factors. An important role is represented by the t-PA and PAI-1. On the contrary, u-PA doesn't change. Samples were all taken at the same time, approximately at the middle of the morning. In patients with Raynaud's phenomenon treated with a prostacyclin stable analogous, we have perceived a clinical improvement, corresponding with a fibrinolytic activity increase.
