Cold agglutinin hemolytic anemia in a patient with adult-onset Still's disease

Abstract

We report on a patient with adult Still's disease who developed, at the onset of her illness, an autoimmune hemolytic anemia (AHA) due to cold agglutinin (CA). Hemolysis spontaneously subsided and CA disappeared before starting therapy with aspirin and prednisone. The occurrence of AHA in patients affected with collagen diseases is currently explained by a loss of tolerance, leading to the emergence of multiple autoreactive clones. In our case the self-limiting course of AHA leads us to propose another interpretation, i.e. that the cold reactive autoantibody might have been related to a transient infection able to play a pathogenetic role in the systemic disease, as suggested by several authors.

Autoimmune Hemolytic Anemia

Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (lyse), leading to an insufficient number of oxygen-carrying red blood cells in the circulation. Discover the latest research on AIHA here.
