What is the prevalence of Antiphospholipid / Hughes Syndrome?

How many people does Antiphospholipid / Hughes Syndrome affect? Does it have the same prevalence in men and women? And in the different countries?


Antiphospholipid syndrome (APS), also known as Hughes syndrome, is a relatively rare autoimmune disorder that affects the blood clotting process. It is characterized by the presence of specific antibodies called antiphospholipid antibodies (aPL) in the blood, which can lead to an increased risk of abnormal blood clot formation.


The prevalence of APS varies across different populations and geographical regions. Estimates suggest that APS affects approximately 1-5% of the general population. However, it is important to note that many individuals with APS may remain undiagnosed due to its diverse and often nonspecific symptoms.


APS can occur at any age, but it is more commonly diagnosed in women of childbearing age. It is a leading cause of recurrent pregnancy loss and complications such as pre-eclampsia and fetal growth restriction. Additionally, APS can also manifest as blood clots in veins or arteries, leading to conditions like deep vein thrombosis or stroke.


Early diagnosis and appropriate management are crucial in APS to prevent complications. Treatment typically involves blood thinning medications to reduce the risk of clot formation. Regular monitoring and close collaboration with healthcare professionals are essential for individuals with APS to manage their condition effectively.

I have always heard it is not as rare as thought to be. So I don't know.

It is more common in women than men and often goes in diagnosed in both cases. In women it can cause miscarriage of pregnancy due to blood clotting in the placenta or umbilical cord. It is not routinely tested for except in women with multiple miscarriages.

It is not more common in women than men, it is just more diagnosed in women because of miscarriage/pregnancy problems. In both men and women it is underdiagnosed because not a lot of doctors know much about it. Most med students (at least here in Canada) cover APS in one day.
