Overview
Thrombophilia is defined as a predilection for clot formation (thrombosis). It could be inherited or acquired, nevertheless most of the time thrombophilia is due to an interplay between both inherited and acquired factors. Protein C deficiency is the most common cause of inherited thrombophilia. This clot formation tendency can lead to venous thrombus formation and subsequent conditions such as pulmonary embolism, deep venous thrombosis, pregnancy loss and stroke. Most of patients with thrombophilia may remain asymptomatic until another thrombophilic condition has been added. symptoms are generally depended on which organ is involved.
Causes
Life Threatening Causes
Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.
Common Causes
- Protein C deficiency (most common cause of inherited hypercoagulable state)
- Prothrombin gene mutation such as Prothrombin G20210A, which is the second most common cause of inherited hypercoagulable state
- Factor V Leiden
- Protein S deficiency
- Antithrombin deficiency
- Medications such as combined oral contraceptives, bevacizumab, lenalidomide, asparaginase, erythropoietin, raloxifene, tamoxifen, tranexamic acid, heparin, ethinylestradiol and hormone replacement therapy
- Systemic lupus erythematosus
- Pregnancy
- Malignancy
Less Common Causes
Less common causes include:[1][3]
- Elevation in some coagulation factors such as VIII, IX and XI
- Dysfibrinogenemia
- Hyperhomocysteinemia and Methylenetetrahydrofolate mutation
- Plasminogen deficiency
- Elevated Lipoprotein(a)
- Klinefelter syndrome
- Polycythemia vera
- Paroxysmal Nocturnal Hemoglobinuria
- Antiphospholipid Syndrome
- Chronic renal insufficiency
