Lead Sponsor: Centre Hospitalier Universitaire Dijon

Brief Summary

Autoimmune hemolytic anemia (AIHA) is an auto-immune disease mediated by specific antibodies targeting red blood cells. Its pathogenesis is not completely understood, and the role of T cells have been rarely studied.

The aim of this study is to compare the frequency of circulating T cells, T cell polarization and functions, notably regulatory T cells, during warm AIHA by comparison to healthy controls.

The role of treatments, such as steroids, will also be determined in patients with warm AIHA.
