Other Names for Thrombotic Thrombocytopenic Purpura

Inherited Thrombotic Thrombocytopenic Purpura

• Familial thrombotic thrombocytopenic purpura
• Upshaw-Schulman syndrome (USS)

Acquired Thrombotic Thrombocytopenic Purpura

• Moschcowitz disease

If you have TTP, you may sometimes hear it referred to as TTP–HUS. HUS, or hemolytic-uremic syndrome, is a disorder that resembles TTP, but is more common in children. Kidney problems also tend to be worse in HUS. Although some researchers think TTP and HUS are two forms of a single syndrome, recent evidence suggests that each has different causes.
