Immune-mediated hemolytic anemia: understanding the nemesis.

IMHA is one of the most common causes of anemia in small animals. Although treatment may be rewarding, many patients do not respond adequately to glucocorticoids alone and require additional immunosuppressive therapy. Some patients may succumb to acute severe anemia and die within the first few weeks of treatment; even if they survive, relapses may occur. IMHA is the nemesis; as our understanding of this disease increases and treatment options expand, it is hoped that survival rates will finally improve.
