Opsoclonus Myoclonus Syndrome - Treatment

Treatment

There is no known definitive cure for OMS. However, several drugs have proven to be effective in its treatment.

Some of medication used to treat the symptoms are:

  • ACTH has shown improvements in symptoms but can result in an incomplete recovery with residual deficits.
  • Corticosteroids (such as prednisone or methylprednisolone) used at high dosages (500 mg - 2 g per day intravenously for a course of 3 to 5 days) can accelerate regression of symptoms. Subsequent very gradual tapering with pills generally follows. Most patients require high doses for months to years before tapering.
  • Intravenous Immunoglobulins (IVIg) are often used with varying results.
  • Several other immunosuppressive drugs, such as cyclophosphamide and azathioprine, may be helpful in some cases.
  • Chemotherapy for neuroblastoma may be effective, although data is contradictory and unconvincing at this point in time.
  • Rituximab has been used with encouraging results.
  • Other medications are used to treat symptoms without influencing the nature of the disease (symptomatic treatment):
    • Trazodone can be useful against irritability and sleep problems
  • Additional treatment options include plasmapheresis for severe, steroid-unresponsive relapses.

The following medications should probably be avoided:

  • Midazolam - Can cause irritability.
  • Melatonin - Is known to stimulate the immune system.

Famous quotes containing the word treatment:

    I feel that any form of so called psychotherapy is strongly contraindicated for addicts.... The question “Why did you start using narcotics in the first place?” should never be asked. It is quite as irrelevant to treatment as it would be to ask a malarial patient why he went to a malarial area.
    William Burroughs (b. 1914)

    Narcissist: psychoanalytic term for the person who loves himself more than his analyst; considered to be the manifestation of a dire mental disease whose successful treatment depends on the patient learning to love the analyst more and himself less.
    Thomas Szasz (b. 1920)

    The treatment of African and African American culture in our education was no different from their treatment in Tarzan movies.
    Ishmael Reed (b. 1938)
