OBJECTIVE: To evaluate the correlation between antiphosphatidylethanolamine antibodies (aPE) and some antiphospholipid antibodies (aPL)-related clinical manifestations in patients with systemic lupus erythematosus (SLE). METHODS: Patients with SLE (n=217) were tested for the presence of aPE, anticardiolipin antibodies (aCL), and lupus anticoagulant (LA). The prospective aPL-related clinical manifestations studied were: thrombosis, thrombocytopenia, recurrent fetal losses, heart valvulopathies, hemolytic anemia, livedo reticularis, and pulmonary hypertension. RESULTS: A total of 109 SLE patients (50.23%) were IgG aPE-positive; 17.51% presented aPE as the sole autoantibody and had some clinical features of aPL-related clinical manifestations. IgG aPE were associated to the presence of heart valvulopathies (p=0.002). A statistical difference was also found when considering high levels of IgG aPE (O.D.>0.600) in patients with livedo reticularis (p=0.008). CONCLUSION: The evaluation of IgG aPE may allow us to detect some more patients with aPL-related clinical manifestations in the SLE population, aPE correlated particularly with valvulopathies and livedo reticularis.
