title: [Prevalence of antiphospholipid antibodies in patients with sickle cell disease].
abstract: Structural abnormalities in erythrocyte membrane are more and more claimed as a determinant factor in the sickle cell disease pathogenesis. This being would have been provided by a new anionic phospholipids distribution and conformation. Phosphatidyl-serine exposing and phosphatidic acid enhancing would induce specific immunoglobulins synthesis. In this study, assessment of antiphospholipid antibodies prevalence was carried out among sickle cell trait patients (n = 35) and homozygous patients (n = 59) as compared to healthy subjects (n = 39). Antiphospholipid antibodies, assayed by ELISA procedure, were significantly higher among the homozygous patients than the sickle cell trait patients ones and highlighted as compared to healthy subjects. Pathologic data were only observed among homozygous patients. These specific antibodies, associated with thrombosis and haemolysis, would have constitute a morbid link and a therapeutic target of this sickness, dominated by homodynamic troubles.
