Summary
Congenital thrombotic thrombocytopenic purpura (TTP), also called Upshaw-Schulman Syndrome or
hereditary or familial TTP is a rare, but severe disease. The purpose of this study is to
determine how infusions of plasma to patients with congenital TTP correlate with symptoms and
signs of activity of the disease, and to determine why some patients need more frequent
infusions of plasma than others to prevent acute attacks of the disease.
