What are the most effective therapies for Guillain-Barr syndrome (GBS)?

The Dutch Guillain-Barr Study Group found that intravenous immunoglobulin and therapeutic plasma exchange were equally effective in the treatment of GBS.1 The Plasma Exchange/Sandoglobulin Guillain-Barr Syndrome Trial Group demonstrated that therapeutic plasma exchange alone, intravenous immunoglobulin alone, and therapeutic plasma exchange immediately followed by a course of intravenous immunoglobulin were all equally effective.2 Intravenous immunoglobulin after a course of therapeutic plasma exchange does not confer additional benefit. Anecdotal evidence suggests that relapses may be more frequent with intravenous immunoglobulin than with therapeutic plasma exchange, but this may result from differences in the length of treatment.3 Corticosteroids are not recommended for the treatment of GBS.4
The French Cooperative Group reported that among patients with severe GBS, 6 days of therapeutic plasma exchange was no more effective than 4 days.5 Research is needed to determine whether intravenous immunoglobulin given for longer than 5 days would be associated with fewer relapses.
Researchers are currently investigating treatments that might prove superior to intravenous immunoglobulin and therapeutic plasma exchange:
• Interferon-β may decrease adhesion and transmigration of lymphocytes and thus provide a potential therapeutic benefit to patients with GBS.6,7
• CSF filtration removes soluble inflammatory mediators and antibodies from sites where myelin or nerve damage may occur.8 CSF filtration could be used in combination with therapeutic plasma exchange or intravenous immunoglobulin to remove inflammatory mediators and antibodies from the spinal fluid and the blood.
• Immunoadsorption with a tryptophan-linked polyvinyl alcohol gel has been investigated in small studies.9,10
• Administration of nerve growth factors might enhance axonal regeneration.11
Further research on the pathogenesis of GBS is needed to develop more specific and more effective treatments. In the meantime, ancillary measures such as effective analgesia, proper timing of intubation and tracheostomy, and deep venous thrombosis prophylaxis can improve outcomes in patients with GBS.3
