In hematology, Autoimmune hemolytic anemia (AIHA) is an "acquired hemolytic anemia due to the presence of autoantibodies which agglutinate or lyse the patient's own red blood cells."[1]
Classification
- Autoimmune hemolytic anemia
- Direct antiglobulin ("Coombs") test-negative
- Direct antiglobulin ("Coombs") test-positive
- Cold agglutinin disease[2]
Diagnosis
- Red-blood-cell-bound immunoglobulin G[3]
- Coombs' test, using the direct method, may have 97% sensitivity for detecting warm antibodies.[4][5]
Treatment
As of 2010, no randomized controlled trials were available.[6] Subsequent studies are below.
Rituximab, a monoclonal antibody, was found to be safe by a systematic review of 21 studies, although only one was a randomized controlled trials.[7]
