Compare the three mechanisms of drug-induced immune hemolysis
What will be an ideal response?
Answer: In drug adsorption, a drug binds to the erythrocyte and then antidrug antibodies attach to the drug. There is extravascular lysis from the interaction between the Fc fragment of the antibody and the Fc receptors of macrophages and resulting phagocytosis of the coated cell. In immune complex, the drug and antibody to it form a complex that adsorbs to the cell membrane and activates complement. This results in intravascular lysis.
In the autoantibody induction type, the drug alters the RBC membrane, causing formation of a neoantigen. The immune system reacts by forming an antibody that reacts with all RBCs.
