Can protein S deficiency go away?
If you acquired protein S deficiency, it should go away when the condition that caused it is gone.
Why is protein S decreased during pregnancy?
Protein S is a cofactor of protein C which lowers the activated factors VIII and V. Pregnancy reduces the level of protein S to 40-50% of normal levels but it is not clear whether the lowered protein S levels increase the risk of developing thrombo-embolism during pregnancy.
Does protein S deficiency cause stillbirth?
Protein S deficiency may be a cause of stillbirth, as a result of a hypercoagulable state associated with throm- bosis of major vessels.
Can protein S levels change?
Normal findings. Protein S levels are low at birth and do not reach adult values until approximately age 6 months. Patient age, sex, health history, the method used for the test, and many other factors can affect laboratory test results, possibly causing results to vary.
How common is protein S deficiency?
Mild protein S deficiency is estimated to occur in approximately 1 in 500 individuals. Severe protein S deficiency is rare; however, its exact prevalence is unknown.
What is the best blood thinner for protein S deficiency?
Rivaroxaban may be considered as a valid anticoagulant alternative in patients with severe inherited protein S deficiency and warfarin-induced skin necrosis.
Does protein S go up or down in pregnancy?
During pregnancy, protein C levels remained unchanged except for a small increase in protein C antigen at 28-32 weeks gestation. The free protein S fell significantly and progressively during pregnancy, although only in about one-third of patients did the level fall below the normal range.
How does protein C affect pregnancy?
Protein C deficiency and pregnancy Women with protein C deficiency have a higher risk of developing clots both during and after pregnancy. That’s because pregnancy is a risk factor for developing blood clots.
Is protein C deficiency a blood disorder?
Protein C deficiency is a disorder that increases the risk of developing abnormal blood clots; the condition can be mild or severe. Individuals with mild protein C deficiency are at risk of a type of blood clot known as a deep vein thrombosis (DVT).
How do you increase protein S?
14 Easy Ways to Increase Your Protein Intake

Does protein S deficiency cause miscarriage?
Protein S deficiency is a rare inherited thrombophilia often associated with fetal losses in pregnancy. It is seen in approximately 1 in 500 to 1 in 3,000 people. Homozygous Protein S deficiency in neonates manifests as a catastrophic and fatal thrombotic complication termed Purpura Fulminans (PF).
What is normal protein S level?
These percentage values should usually fall between 60 and 150. There might be slight differences among testing facilities. High levels of protein S are not typically cause for concern, whereas low levels may increase your risk of blood clots.
What are the treatment options for protein S deficiency during pregnancy?
Many experts recommend that women with protein S deficiency and a history of fetal loss, and severe or recurrent eclampsia, receive low-dose aspirin and prophylactic-dose low molecular weight heparin (LMWH) therapy during pregnancy, with the LMWH prophylaxis extending for 6 weeks postpartum.
What are the causes of protein S deficiency?
Some causes of acquired protein S deficiency include vitamin K deficiency, consumption from thrombosis, DIC, or invasive procedures, decreased hepatic synthesis, pregnancy, estrogen, sickle cell anemia, HIV infection, varicella infection, nephrotic syndrome, and acute phase reactions (due to elevated C4b-binding protein). 1.
What is the role of protein s in pregnancy?
Third Trimester. % of normal. Protein S is a vitamin K dependent protein that is a cofactor for activated protein C (APC)-mediated degradation of coagulation factors Va and VIIIa, It also appears to act as a cofactor for tissue factor pathway inhibitor (TFPI), inhibiting tissue factor mediated factor X activation.
Is LMWH safe during pregnancy and postpartum?
For women with a prior VTE history and confirmed protein S deficiency, experts recommend prophylactic or intermediate dosing of LMWH during pregnancy and for 6 weeks postpartum.
