[13] [14] [5] [4] [2] [15] Pregnancy [7] and ethinylestradiol (EE)-containing combined birth control pills increase APC resistance as measured by either the aPTT- or ETP-based test. [ 4 ] [ 5 ] [ 15 ] EE-containing birth control pills show different degrees of influence on the ETP-based test depending on the progestin , which may be due to ...
Factor V Leiden (rs6025 or F5 p.R506Q [1]) is a variant (mutated form) ... Women with factor V Leiden have a substantially increased risk of clotting in pregnancy ...
APC resistance is the inability of protein C to cleave Factor Va and/or Factor VIIIa, which allows for longer duration of thrombin generation and may lead to a hypercoagulable state. This may be hereditary or acquired. [4] The best known and most common hereditary form is Factor V Leiden, which is responsible for more than 95% of cases. [5]
[5] Pregnancy after the age of 35 augments the risk of VTE, as does multigravidity of more than four pregnancies. [2] Pregnancy in itself causes approximately a five-fold increased risk of deep venous thrombosis. [6] Several pregnancy complications, such as pre-eclampsia, cause substantial hypercoagulability. [2]
In general, men are more likely than women to experience repeated episodes of venous thrombosis. [5] People with factor V Leiden are at a relatively low risk of thrombosis, but may develop thrombosis in the presence of an additional risk factor, such as immobilization. Most people with the prothrombin mutation (G20210A) never develop thrombosis ...

Antiphospholipid syndrome is known for causing arterial or venous blood clots, in any organ system, and pregnancy-related complications.While blood clots and pregnancy complications are the most common and diagnostic symptoms associated with APS, other organs and body parts may be affected like platelet levels, heart, kidneys, brain, and skin.
The last category, alterations in the constitution of blood, [6] has numerous possible risk factors such as hyperviscosity, coagulation factor V Leiden mutation, coagulation factor II G2021A mutation, deficiency of antithrombin III, protein C or S deficiency, nephrotic syndrome, changes after severe trauma or burn, cancer, late pregnancy and ...
