Which statement about Guillain-Barré syndrome treatment is correct?

• A. Antibiotics are the first-line therapy
• B. Corticosteroids accelerate recovery
• C. Routine plasmapheresis is contraindicated in all patients
• D. Both intravenous immunoglobulin (IVIG) and plasma exchange shorten recovery

Answer: (D)

In Guillain-Barré syndrome, the aim is to blunt the autoimmune attack on peripheral nerves to speed recovery. Two established first-line treatments do this effectively: intravenous immunoglobulin (IVIG) and plasma exchange. They work by different but complementary mechanisms to reduce the immune-mediated damage—IVIG modulates the immune response, while plasma exchange removes circulating autoantibodies and inflammatory mediators. When started early, both therapies shorten the time to independent function and can lessen the need for mechanical ventilation in more severe cases. Antibiotics aren’t the primary treatment because GBS is not driven by a bacterial infection; they don’t alter the disease process, though antibiotics may be used if a concurrent infection is present. Corticosteroids have not shown reliable benefit in speeding recovery for GBS. Routine plasmapheresis is not universally contraindicated; it is a recognized treatment option in appropriate patients, though not every case is suitable. Therefore, the correct statement is that both IVIG and plasma exchange shorten recovery.
