A double blind placebo controlled trial of recombinant tissue plasminogen activator in the treatment of digital ischemia in systemic sclerosis.

ABSTRACT

The treatment of digital ischemia in systemic sclerosis remains inadequate. We report a double blind, placebo controlled trial of recombinant tissue plasminogen activator (rtPA), a potent thrombolytic agent. Ten patients received rtPA. A potent, acute fibrinolytic effect was observed. During the infusion of rtPA, improvements in skin blood flow were seen. These improvements were shortlived.
