About the study

Hypothesis is that the occurrence of nocturnal Vaso-Occlusive Crisis (VOC) and priapism in
adults might be related to episodes of nocturnal desaturation secondary to a sleep apnea
syndrome. Investigator hypothesize that chronic biological consequences of Obstructive Sleep
Apnea (hypercoagulability, endothelial dysfunction …) favour VOC and acute manifestations
(nocturnal desaturation) favour nocturnal VOC.

The confirmation of this hypothesis will lead investigator to propose a systematic screening
of obstructive sleep apnea (OSA) in patients with nocturnal VOC. Moreover, systematic
treatment of OSA in sickle cell patients could help significantly reduce the number and
severity of nocturnal VOC.
