Covering Autoimmune Diseases

Cardiolipin antibodies

Cardiolipin, and other related phospholipids, are lipid molecules normally found in the cell membranes and in platelets. They play an important role in the blood clotting process.

When antibodies are produced against cardiolipin they increase an affected patient’s risk of developing recurrent inappropriate blood clots in both arteries and veins. Cardiolipin antibodies are also associated with thrombocytopenia, recurrent miscarriages (especially in the 2nd and 3rd trimester), and with premature labour and preeclampsia.

Cardiolipin antibodies are frequently seen with autoimmune disorders, such as systemic lupus erythematosus (SLE), and with other antiphospholipid antibodies, such as lupus anticoagulant. When patients experience thrombosis, recurrent miscarriages, thrombocytopenia, cardiolipin antibodies, and/or another antiphospholipid antibody, they may be diagnosed with antiphospholipid syndrome (APS). APS can be primary with no underlying autoimmune disease, or secondary, existing with a diagnosed autoimmune disorder.

Moderate to high levels of one or more of the classes of cardiolipin antibodies that persist when tested again 6 weeks later indicate the likely continued presence of that specific antibody.

  1. Hello,
    I have been living with APS (primary) for 30 years, having been diagnosed at 21.
    I have been taking Warfarin for almost all of this time and had heart surgery eight years ago, for which I take further medication.
    Recently I was diagnosed with autoimmune Thyroid disease.
    I have started taking Levothyroxin but I am told it will have to be increased very slowly as it couls interfere with other meds I take.
    For a while, I felt a lot better, my hair stopped falling out and my energy increased, i lost some of the weight I had recently put on.
    However, I am on 75 micrograms and I am feeling awful again. My hair is falling out even more. The worst thing for me is that my voice is so husky and low that I am embarrassed to speak.
    I used to sing.
    Now i feel too awful to hear my voice and I used to love it so.
    Any advice?
    I am seeing my GP again on Thursday.

    Thanks in advance.


    1. Dear Miriam,
      living with a chronic disease is a lifelong challenge, as you certainly know. Be brave, hang on and trust your doctor, he or she should be your partner in managing your condition.
      Maybe, getting in contact with a patient organisation would be helpful for you, e.g. the EULAR Pare in Europe.
      I wish you all the best
