A diagnosis of aTTP means you may hear new terms. Understanding these terms may help you feel more prepared for conversations with your doctor.
aTTP (acquired thrombotic thrombocytopenic purpura): A rare blood disorder that develops when the immune system stops ADAMTS13, a protein, from working properly. Without this protein, the body creates too many blood clots.
Acquired: Describes a condition that is developed later in life. It may be unknown why aTTP was developed.
Thrombotic: Refers to the small blood clots that form inside blood vessels.
Thrombocytopenic: Means having a low platelet count.
Purpura: Red- or purple-colored spots on the skin that do not go away when pressure is applied. It may look like a bruise.
ADAMTS13: An enzyme, or protein molecule, needed to prevent the body from making more blood clots than it needs.
Anemia (uh-NEEM-ee-uh): A drop in the number of red blood cells in the body. Red blood cells carry oxygen throughout the body.
Episode (or Event): An acute period when someone is affected by an illness.
Immune system: The body’s natural defense system against a harmful organism that can make you sick.
Immunosuppressive therapy/Immunosuppressant: Treatment that helps decrease the activity of the immune system, which is overactive during an episode of aTTP.
Intravenous (IV): Entering the body through a vein.
Jaundice: Yellowing of the skin and eyes.
Microthrombi: A blood clot located in a small blood vessel.
Petechiae (puh-tEE-kee-ie): Small red or purple spots less than 1/8 of an inch in size on the skin.
Plasma exchange (PEX): A procedure that removes and replaces a person’s blood plasma. This process helps clean the body by removing things it has too much of (such as immune cells) and adding things it has too little of (such as ADAMTS13 and platelets).
Platelets: A small cell found in the blood that is involved in clotting.
Recurrence: Any aTTP episode that follows the first aTTP episode.
Red blood cell: A cell that carries oxygen from the lungs to all parts of the body and then carries carbon dioxide back to the lungs to exhale out of the body.
Specialty pharmacy: A pharmacy that delivers medicines that are not available through a local pharmacy. It often provides services including:
Subcutaneous (SC or subQ): Injected into the body under the skin.
von Willebrand factor (vWF) (vawn vil-uh-brahnt): One of the components in your blood that helps your platelets stick together.
