“Anti-cardiolipin antibodies are autoantibodies that use cardiolipin as a target antigen. Common causes include the following: first, consider antiphospholipid antibody syndrome. In this condition, anticardiolipin antibodies tend to be high titer and are associated with a history of arteriovenous embolism or recurrent adverse pregnancies. In addition, elevated anticardiolipin antibodies are seen in peculiar diseases. First, other autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, and desiccation syndrome; second, viral infections, commonly chickenpox virus, rubella virus, and mumps virus, can cause increased anticardiolipin antibodies; third, diseases of the mycoplasma system, which also cause increased anticardiolipin antibodies; and fourth, oral medications, such as clopidogrel, which can also cause increased anticardiolipin antibodies. The fourth is oral medications, such as chloropyrazine. In addition, a very small number of normal elderly people without obvious signs, due to unknown reasons, will also appear the antibody increase, so when there is an increase in anticardiolipin antibodies must be systematic examination, systematic treatment, it is recommended that oral antiplatelet drugs, as well as anticoagulant drugs, if necessary, go to a regular hospital for treatment.”
