AbstractSickle cell disease is syndromic, associating a hemolytic anemia, a vaso-obstructive vascular disease, and an infectious risk linked to the precocity of the splenic function loss. The willingly hyperacute and potentially fatal character of the two last elements of the pathophysiologic syndrome, has, quite rightly, focused the therapeutic researches on them. Great success in those two domains have allowed a very important gain in life expectancy. However, chronic progressive organ dysfunction began to appear in older than 25 years-old patients. It concerns mainly renal, hepatic, cardiac functions and pulmonary arterial pressure and may lead to organ failure and premature death. Since some 25 years, the clinical research demonstrated an association between such complications and intravascular hemolytic rate, and it turned to a causative relationship. This present paper try to summarize the actual knowledge on the structural and genetic aspects of sickle cell anemia hemolysis. © 2023 Société nationale française de médecine interne (SNFMI).
