TTP - treatment
Plasmapheresis
vWD presents as ____
Mucocutaneous bleeding
Treatment for vWD
Cryoprecipitate (vWF) + DDAVP (release vWF)
Vitamin K deficiency - labs
Prolonged PT, deficient factors 2, 7, 9, 10, C, S
Treatment for vitamin K deficiency
Normal liver fxn – vitamin K supplements
Liver disease or acute hemorrhage – FFP
Hereditary hemorrhagic telangiectasia - gene deficiency
Endoglin (CD 105)
Function of antithrombin 3
Serine protease - inhibits thrombin activation
AT3 requires what?
Heparin
AT3 deficiency causes increased risk of _____
Clotting (via thrombin activation)
AT3 deficiency - presentation
Recurrent LE thrombophlebitis, DVT, leg ulcers, PE
AT3 deficiency - treatment
Refractory?
Anticoagulants (heparin)
AT3 replacement
Protein C/S deficiency - treatment
Warfarin
Factor V Leiden - risk?
Treatment?
Thromboembolism
No episodes = monitor, etc.
Prior episode(s) = lifelong anticoagulation
Prothrombin 20210
Risk?
G-A mutation, causing increased prothrombin activity
Thrombosis
Common occurrences w/ antiphospholipid syndrome
- Thromboembolism
- Miscarriage
- Thrombocytopenia
- Cerebral ischemia/stroke
- UBOs on MRI
Diagnosis of antiphospholipid syndrome (3)
- Prolonged PTT
- No correction using normal plasma
- Neutralization w/ excess phospholipid
Specific diagnostic test for antiphospholipid syndrome
Dilute Russell viper venom time (DRVVT)
Treatment for antiphospholipid syndrome
Hx of thromboembolism –> lifelong anticoagulation
ITP - treatment
Prednisone
Reactive leukocytosis, thrombocytopenia, prolonged PT and PTT, no RBC fragments on smear
How to diagnose?
DIC - from infection
Dx = D-dimer level
DIC treatment
Treat the cause, FFP, cryoprecipitate, platelet transfusions
Hyaline thrombi that occlude the capillaries of basically every organ
TTP
Patient on prolonged antibiotics, PT starts to get longer
Vitamin K deficiency - no microbial production
Connective tissue disease, prolonged PTT that doesn’t correct, valvular heart disease, recurrent stroke, thrombocytopenia
Antiphospholipid syndrome
