Anticardiolipin antibodies are found in most autoimmune disorders and especially in those that involve decreased mitochondrial function (essentially all fatiguing illnesses and many other chronic illnesses, such as neurodegenerative diseases, neurobehavioral diseases, among other diseases). Cardiolipin is a specialized lipid that is mostly found in the inner mitochondrial membrane where it is essential for oxidative phosphorylation or the production of high-energy molecules in the cell that are necessary for metabolism and cell function. Reduction of the cardiolipin molecules results in leaky mitochondrial membranes, and these membranes must not be leaky or high-energy molecules can’t be produced, resulting in fatigue. Infections damage cardiolipin and other membrane phospholipids by oxidation—the infections produce peroxides that oxidize the membrane lipids, and cardiolipin molecules are particularly sensitive. Once damaged, they must be removed and antibodies can be made against them during this process. These same oxidative events can damage the endothelial cells lining the blood vessels, resulting in increased platelet aggregation and increased production of platelets to compensate for this.
