Worsening of anemia is very common in sickle cell disease. It is important to investigate specific complications related to sickle cell disease but also other causes of anemia in general. Transfusions or exchange transfusions are major therapeutic options and are frequently used for acute complications of sickle cell disease but also for primary and secondary prevention of some of the chronic complications. ⋯ A strong collaboration between the patient's expert center, the Blood center and the patient's hospitalization unit is required to make decisions. © 2023 Société nationale française de médecine interne (SNFMI).

Review
[Monogenic auto-inflammatory diseases associated with actinopathies: A review of the literature].
Auto-inflammatory diseases (AIDs) are diseases resulting from an inappropriate activation of innate immunity in the absence of any infection. The field of monogenic AIDs is constantly expanding, with the discovery of new pathologies and pathophysiological mechanisms thanks to pangenomic sequencing. Actinopathies with auto-inflammatory manifestations are a new emerging group of AIDs, linked to defects in the regulation of the actin cytoskeleton dynamics. ⋯ However, the diagnosis remains genetic, and several differential diagnoses must be considered. The pathophysiology of these diseases is not yet fully elucidated, and studies are needed to better clarify the inherent mechanisms that can guide the choice of therapies. In most cases, the severity of the picture indicates allogeneic marrow transplantation.

Familial Mediterranean fever is the most common monogenic auto-inflammatory disease in the world. It mainly affects people originating from the Mediterranean region. The mutated gene is MEFV, which codes for pyrin. ⋯ The diagnosis is suspected on the basis of clinical and anamnestic factors and confirmed by genetic analysis. These guidelines also suggest a "treat-to-target" approach to disease management, particularly in case of suspected colchicine resistance - a very rare situation that should remain a diagnosis of elimination, especially after colchicine compliance has been verified. Two special situations are also addressed in these guidelines: kidney failure and pregnancy.

Sickle 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. ⋯ 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).
