Abstract:
COVID-19 has rarely been associated with immune-mediated phenomena such as autoimmune haemolytic anaemia (AIHA). Both cold hemolysis with cold agglutinin detection and warm haemolysis have been described with variable prognoses. Current treatment regimens are based on experience with other case series and case reports, which still represent a clinical challenge. Corticosteroids, red cell transfusions and rituximab have been successfully employed. We present 3 cases of AIHA in the context of COVID-19 disease, the first case successfully treated with plasma exchange and long-term follow-up of the 3 cases showing complete remission of anaemia.
