Plasma Exchange and Immunoglobulins – Indications and Use

Plasmapheresis (Plasma Exchange):

  • Definition: Plasmapheresis, also known as therapeutic plasma exchange, involves removing the **plasma portion** of a patient’s blood and replacing it with either **albumin** or fresh plasma.

 

  • Mechanism of Action:

Plasmapheresis removes pathogenic antibodies that interfere with neuromuscular function.

By eliminating these antibodies, normal neuromuscular activity is restored.

 

  • Indications:

Effective in chronic inflammatory demyelinating polyneuropathy, Guillain-Barré-syndrome (GBS) in adults, multifocal motor neuropathy, dermatomyositis, stiff-person syndrome, and myasthenia gravis exacerbations (but not stable disease).

 

Considered for Lambert-Eaton myasthenic syndrome and pediatric Guillain-Barré-syndrome (GBS).

 

Not recommended for inclusion body myositis, post-polio syndrome, IgM paraproteinemic neuropathy, and small fiber neuropathy.

 

  • Clinical Use: Often used in the ICU for neuromuscular disorders.

 

 

Intravenous Immunoglobulins (IVIG):

 

  • Definition: IVIG is a therapy containing healthy antibodies from blood donors, administered intravenously.

 

  • Mechanism of Action:

High doses of IVIG can block damaging antibodies associated with GBS and myasthenic crisis.

 

  • Indications:

Recommended for **chronic inflammatory demyelinating polyneuropathy**, GBS in adults, multifocal motor neuropathy, dermatomyositis, stiff-person syndrome, and myasthenia gravis exacerbations (but not stable disease).

 

Also useful for **Lambert-Eaton myasthenic syndrome** and pediatric GBS.

 

Not recommended for inclusion body myositis, post-polio syndrome, IgM paraproteinemic neuropathy, and certain small fiber neuropathies.

 

  • Clinical Use: IVIG remains a mainstay of treatment in the ICU for many neuromuscular disorders.
