Classification AIHA can be classified as warm autoimmune hemolytic anemia or<unk> , which includes<unk>  agglutinin disease and paroxysmal<unk>  hemoglobinuria. These classifications are based on the characteristics of the autoantibodies involved in the pathogenesis of the disease. Each has a different underlying cause, management, and prognosis, making classification important when treating a patient with AIHA. ---- :Autoimmune hemolytic anemia ::*Warm-antibody type :::*Primary :::*Secondary (lymphoproliferative disorders, autoimmune disorders) ::*Cold-antibody type (anemia) :::*Primary<unk>  agglutinin disease :::*Secondary<unk>  agglutinin syndrome ::::*Associated with malignant disease ::::*Acute, transient, infection-associated (acute<unk>  antibody mediated AIHA complicating Mycoplasma pneumoniae or viral infections ) ::::*Chronic (lymphoproliferative disorders) ::*Paroxysmal<unk>  hemoglobinuria :::*Idiopathic :::*Secondary ::::*Acute, transient (Infections other than syphilis) ::::*Chronic (syphilis) ::*Mixed<unk> - and warm-antibody type :::*Idiopathic :::*Secondary (lymphoproliferative disorders, autoimmune disorders) ::*Drug-induced immune hemolytic anemia :::*Autoimmune type :::*Drug absorption type :::*Neoantigen type
