Overview
- Annual thrombotic risks are variable and depend on the underlying thrombophilia.[1]
Natural History
- Refer to the clinical symptoms section regarding early clinical features of patients with thrombophilia.
- If left untreated, the annual incidence of incident thrombosis in asymptomatic patients with Factor V Leiden and (Prothrombin G20210A) (<0.06%) is low.[2] The risk is approximately equivalent to treatment with oral contraceptives (OCPs). Whereas the annual incidence of significant bleeds is approximately 2-3%.[3]
- Studies performed by Christiansen et al and Baglin et al revealed that inherited thrombophilia from factor V leiden and prothrombin G20210A did not predict for recurrent thrombosis.[4][5]
- Christiansen et al and De Stefano et al observed a mild increased risk for recurrent thrombosis in patients with protein C, protein S, and antithrombin deficiency.[4][6]
- OCPs, hormone replacement therapy, and pregnancy can significantly increase thrombotic risk in patients with thrombophilia.[7]
- Certain high risk thrombophilias require indefinate anticoagulation.
Complications
- Patients with primary hypercoagulable states develop thrombotic complications mostly in the settting of aquired risk factors which include trauma, surgery, immobility, pregnancy and use of OCPs.
- Deep vein thrombosis and pulmonary embolus are the most common complications.
| Thrombophilic state | Thrombotic risk[2] |
|---|---|
| Trauma/General surgery | Modest |
| Age > 60 | Modest |
| Immobilization | Modest |
| Pregnancy | Modest |
| Hormone therapies | Modest |
| Factor V Leiden heterozygosity | Modest |
| Prothrombin mutation | Modest |
| Homocysteinemia | Modest |
| Increased factor VIII levels | Modest |
| Increased factor IX levels | Modest |
| Increased factor XI levels | Modest |
| Protein C and S deficiency | Intermediate |
| Dysfibrogenemia | Intermediate |
| Malignancy | High |
| APLS/Lupus anticoagulant | High |
| Myeloproliferative disorders/hyperviscosity | High |
| PNH | High |
| Orthopedic surgery | High |
| Antithrombin deficiency | High |
| Factor V Leiden homozygosity | High |
Modification of thrombotic risk with concurrent hormone exposure.
| Thrombophilic state | Annual Incidence (%) | Relative Risk |
|---|---|---|
| Normal | 0.008 | 1 |
| Factor V leiden heterozygous | 0.06 | 3-10 |
| Factor V leiden homozygous | 0.5-1 | 80 |
| Prothrombin G20210A | 0.02 | 1-5 |
| Oral contraceptive (OCP) | 0.03 | 4 |
| OCP and factor V leiden heterozygous | 0.3 | 35 |
| OCP and factor V leiden homozygous | 100 | |
| OCP and prothrombin G20210A | 16 | |
| OCP and protein C/S, or antithrombin III deficiency | 9.7 | |
| Pregnancy | 7 | |
| Pregnancy and factor V leiden heterozygous | 35 | |
| Cancer | 5 | |
| History of venous thrombosis | 50 |
Data were extracted from multiple sources.[1][2][7]
Prognosis
- Certain thrombophilic conditions are high risk and require consideration for lifelong anticoagulation. In these cases, expert consultation is recommended.
| Possible indications for lifelong/prophylactic anticoagulation |
|---|
| Antiphospholipid syndrome |
| Paroxysmal nocturnal hemoglobinuria |
| Recurrent thrombosis regardless of underlying thrombophilia |
| History of life-threatening thrombosis or atypical locations |
| Malignancy with history of thrombosis |
