Warm autoimmune hemolytic anemia (WAIHA) is the most common form of autoimmune hemolytic anemia (AIHA), caused by IgG autoantibodies targeting red blood cells at body temperature. Clinicians differentiate it from other types of hemolytic anemia such as cold AIHA, mixed autoimmune hemolytic anemia, and secondary hemolytic anemias, which is crucial for accurate diagnosis and treatment planning.
WAIHA patients often experience fatigue, jaundice, pallor, and shortness of breath due to ongoing hemolysis. Though autoimmune hemolytic anemia is rare, WAIHA represents approximately 70–80% of cases, typically affecting adults with a slight female predominance. Enhanced diagnostic techniques, including testing with WAIHA serum, have improved early detection and patient management worldwide.
First-line therapy generally involves corticosteroids, with rituximab, immunosuppressants, or splenectomy for resistant cases. Despite these interventions, variable response rates and relapse continue to influence the warm autoimmune hemolytic anemia prognosis, underscoring the need for more effective and targeted treatment options.
The WAIHA market is witnessing increased activity, driven by biologic innovations and pipeline expansion. Major pharmaceutical initiatives, including Sanofi warm autoimmune hemolytic anemia programs, are advancing therapies aimed at improving response durability and reducing relapse risk. Focus on differentiating warm vs cold AIHA and developing targeted therapies is shaping the evolving market landscape.
As scientific understanding of autoimmune hemolytic anemias deepens and novel treatments reach the clinic, the WAIHA field is poised for steady growth. Emerging therapies offer the promise of more precise and effective care for patients affected by this rare and serious disorder.
