What is Drug-induced AIHA (diAIHA)?

By William Aird

Categorized as:

  • Drug-independent – via auto-antibodies
  • Drug-dependent antibodies
    • Activates a response only while the drug is present.
    • Drug-dependent antibodies may specifically attach to the drug, the drug’s metabolites, and/or drug-RBC neoantigens.
    • Two types:
      • Hapten type which is due to the noncovalent binding of the drug to the RBC which is then targeted by the autoantibody in a drug-dependent manner.
      • Drug-autoantibody immune (ternary) complexes that are mediated by a complement-dependent hemolysis that is drug dependent.
