After participating in this educational activity, participants should be able to:
- Discuss the mechanism of production of drug-induced antibodies and their serologic classification.
- List some of the common drugs involved in DIHA.
- Describe the immunohematologic findings in DIHA.
- Discuss the special tests done at a reference laboratory for DIHA.
- Discuss the clinical findings in patients with DIHA.
Drug-induced immune hemolytic anemia (DIHA) is fortunately rare, but may be challenging for both the clinician and the blood bank. A high level of suspicion by the clinician may prompt the possibility of DIHA, however, serological testing is needed to confirm the diagnosis and often times, the blood bank raises concern for DIHA in a patient. This program will discuss the clinical and immunohematologic findings seen by a hospital blood bank which should raise concern for DIHA in a patient with immune hemolysis, and additional testing done by a reference laboratory. DIHA testing may mimic both warm and cold autoantibodies and an accurate patient history plays a key role in differential diagnosis.
