Founded in 2005, APS Foundation of America, Inc. (APSFA) is the only United States nonprofit health agency dedicated to bringing national awareness to Antiphospholipid Syndrome (APS), the major cause of multiple miscarriages, thrombosis, young strokes and heart attacks. We are a volunteer run, community based 501(c)3 non-profit Public Charity organization and is dedicated to fostering and facilitating joint efforts in the areas of education, support, public awareness, research and patient services.  The APSFA’s Medical Advisory Team includes nationally & internationally recognized experts on Antiphospholipid Syndrome.

APS is an autoimmune disorder in which the body recognizes certain normal components of blood and/or cell membranes as foreign substances and produces antibodies against them. There are two known forms. APS may occur in people with systemic lupus erythematosus, other autoimmune disease, or in otherwise healthy individuals.

APS is also referred to as APLS or APLA in the United States and formerly Hughes Syndrome or Sticky Blood in the UK.

What is Antiphospholipid Syndrome (APS)?

APS is associated with recurrent clotting events (thrombosis) including premature stroke, repeated miscarriages, phlebitis, venous thrombosis and pulmonary thromboembolism. It is also associated with low platelet or blood elements that prevent bleeding. Recently, however, even more disease states have been linked with APL including premature heart attack, migraine headaches, various cardiac valvular abnormalities, skin lesions, abnormal movement/chorea, diseases that mimic multiple sclerosis, vascular diseases of the eye that can lead to visual loss and blindness.

Find a Doctor

With the help of our Medical Advisory team, our forum members, and other APS patients, we have compiled a list of doctors who are familiar with APS and who currently treat APS patients. The doctors on this list may not be “experts” in APS, but other APS patients have recommended them. The APS Foundation of America, Inc. does not endorse any of these doctors—they were simply suggested to us by others who have had luck with them. Every APS case is unique, so you may not have the same positive experience. Please be sure to call their office to inquire directly to ensure that they accept your health insurance and are accepting new patients.
