Study Notes
Coagulation Disorders
- Coagulation disorders arise from problems with platelets, clotting factors, or both.
- Coagulopathy is any condition affecting blood clotting ability.
- Suspected when standard bleeding-control methods fail.
- Can develop secondary to autoimmune conditions or significant blood loss.
- Microemboli paradoxically deplete clotting factors, leading to hemorrhages alongside intravascular clotting.
Idiopathic (Immune) Thrombocytopenic Purpura (ITP)
- An autoimmune disorder impacting platelet lifespan.
- Antiplatelet antibodies shorten platelet life, despite normal production.
- Can cause severe bleeding after procedures like C-sections or lacerations.
- Mortality rate for adults with ITP is 5%.
Thrombotic Thrombocytopenic Purpura (TTP)
- Characterized by abnormal platelet clumping in capillaries due to autoimmune reaction.
- Leads to low platelet count and inadequate clotting response to injury.
- Can result in kidney failure, heart attack, stroke, and is deadly within three months if untreated.
- Mortality rate is 10-20%.
Heparin-Induced Thrombocytopenia (HIT)
- An immunity-mediated clotting disorder triggered by heparin therapy.
- Causes unexplained low platelet count.
- Mortality rate is 30%.
Disseminated Intravascular Coagulation (DIC)
- A life-threatening condition with simultaneous clotting and anti-clotting mechanisms.
- Patients risk both internal and external bleeding, organ damage due to micro-clots.
Hemophilia
- An inherited bleeding disorder due to deficiencies in factor VIII or factor IX.
- Often triggered by minor trauma.
- Relatively common, typically diagnosed in early childhood.
- Affects over one million individuals.
