Antiphospholipid syndrome (APS)
Antiphospholipid syndrome (APS) is an autoimmune condition that increases the risk of blood clots. It occurs when the immune system mistakenly produces antibodies against phospholipids, which are essential components of cell membranes.
Symptoms of APS can vary widely. Some individuals may experience recurrent blood clots, which can lead to deep vein thrombosis (DVT) or pulmonary embolism. Others might have complications during pregnancy, such as repeated miscarriages or pre-eclampsia. In rarer cases, APS can cause strokes or transient ischaemic attacks (TIAs), as well as skin rashes or livedo reticularis, which is a mottled skin appearance.
The exact cause of antiphospholipid syndrome isn't fully understood, but it can occur on its own (primary APS) or alongside other autoimmune disorders, such as lupus (secondary APS). Certain risk factors may increase the likelihood of developing APS, including a family history of blood clots or autoimmune diseases, and certain infections or medications.
Treatment for APS focuses on reducing the risk of blood clots. This usually involves anticoagulant medications, such as warfarin or heparin, which help to thin the blood. In some cases, lifestyle changes, like maintaining a healthy weight, regular exercise, and avoiding smoking, can also be beneficial.
It’s important to seek medical advice if you experience symptoms like swelling, pain in the legs, sudden shortness of breath, or unusual bleeding, particularly if you have a history of blood clots or autoimmune conditions. Early diagnosis and management are crucial in preventing serious complications associated with antiphospholipid syndrome.
