Treatment of Type II & III hypersensitivity is best summarized as:

• A. Allergen avoidance
• B. Interferon, cyclophosphamide, cyclosporin infusions
• C. Plasmapheresis
• D. No cure, symptom control only

Answer: (D)

In Type II and Type III hypersensitivity, the injury is caused by antibodies targeting cells or by immune complexes that deposit in tissues. Because these conditions are so disease-specific and vary widely in mechanism and presentation, there isn’t a single treatment that cures all of them. Therapies are chosen to reduce antibody levels or immune complex burden and to dampen inflammation, but they don’t guarantee a cure across the whole group. Plasmapheresis can help in some situations by removing antibodies or immune complexes, and immunosuppressants can control disease activity, yet these approaches are not universally curative. Allergen avoidance targets Type I hypersensitivity, and the other listed options aren’t universally applicable to every Type II or III condition. Therefore, the broad, general takeaway is that treatment often focuses on control of symptoms and suppression of the immune response rather than a universal cure.
