Clinical Significance
Phospholipid autoantibodies specific to phosphatidylinositol (PI), phosphatidylglycerol (PG), phosphatidylserine (PS), phosphatidylethanolamine (PE), phosphatidylcholine (PC), phosphatidic acid (PA), cardiolipin (CL), and sphingomyelin are found in hematologic autoimmune diseases, especially antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE). APS is characterized by arterial and venous thrombosis, thrombocytopenia, and recurrent fetal loss; thrombosis, thrombocytopenia, and hemolytic anemia also occur in SLE and are associated with the presence of phospholipid autoantibodies. Women with infertility, showing spontaneous abortion or in vitro fertilization failure, demonstrate PI autoantibodies in 25% of cases.
