2007 OCT 1 -- Current study results from the report, "Intravenous immunoglobulin as an adjunct to plasma exchange for the treatment of chronic thrombotic thrombocytopenic purpura," have been published. According to recent research from Hamilton, Canada, "Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease. Therapeutic plasma exchange (TPE) is the most effective therapy; however, despite TPE, about one-third of TTP patients will relapse."

"A subset of patients with TTP has antibodies to ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) and may become resistant to conventional treatments. We describe a patient with TTP and high-titre anti-ADAMTS13 antibodies who developed a chronic, relapsing course of TTP despite frequent TPE. Once adjuvant treatment with intravenous immunoglobulin (IVIG) was added, remission was achieved. Even during remission, anti-ADAMTS13 antibodies remained elevated," wrote J.C. Moore and colleagues, McMaster University, Health Science Center.

The researchers concluded: "We conclude that IVIG may sustain remission in some patients with chronic, relapsing TTP."

Moore and colleagues published their study in Vox Sanguinis (Intravenous immunoglobulin as an adjunct to plasma exchange for the treatment of chronic thrombotic thrombocytopenic purpura. Vox Sanguinis, 2007;93(2):173-5).
