Summary

Despite important advances in the current understanding of sickle cell vaso-occlusion, the basis of its control and prevention remain partially unknown. The primary purpose is to test the hypothesis of a control of the sickle cell vaso-cocclusive (VOC) process by the anti band 3 antibodies by assessing the level of these antibodies in the steady state and during the crises in SCA patients. To assess the relationship between the level of band 3 antibodies, the oxidation status, the expression of microparticles and the hemorheological alterations of the sickle red cells (SS RBs), the severity of VOC.

SCA patients (SS genotype)

The clinical data relative to the patients will be collected in each of these stages (CVO, basic state). Besides, to estimate the severity of the CVO, we shall use an index of severity of the episode ( IS2) adapted from the one who was validated by our group to stratify the severity of vasoocclusifs episodes at the drepanocytic child SS. Main clinical parameters: taken of analgesic at home (level), temperature in the admission, SaO2 in the admission, number of painful sites, thoracic pain with or without associated cough, score EVA in the entrance, feeling of the patient of bigger gravity of the CVO with regard to its crises previous, heart rate to the admission, … Main biological parameters: rate of leukocytes, of polynucléaires neutrophiles, of réticulocytes, Lactate déshydrogénase, of haemoglobin, C-reactive Protein … The biological data can be studied according to their raw rate or according to their difference with their basic value (in the stable state).
