Woman: Toxin Still Powerful Years Later | theledger.com

CIGUATERA

Dr. Omar Sanchez sends us a link about a woman who had ciguatera and who still is symptomatic years later. This can be read in the "ledger" at this address: http://snipurl.com/nrxr

The following is information that we have on our web site about this toxin and the condition it can cause.

* The toxin, icthyosarcotoxin, is heat stable, lipid soluble and comes from the dinoflagellate Gambierdiscus toxicus. It is common in the tropics, concentrated up the food chain and is seen in eels, red snapper, amberjack and so forth.

* Symptoms: vary, the usual onset occurs in the first 12 hours and can last for ten to twelve days. The GI symptoms are followed by myalgias, arthralgias and paresthesias. There is the heat/cold reversal phenomenon and this is supposed to be diagnostic. Neurological symptoms may take months to resolve and occasionally may be permanent. Symptoms are aggravated by alcohol and by eating a fish only slightly affected.

* Treatment: nonspecific, primarily supportive. Suggested treatment has included calcium gluconate, corticosteroids, atropine, vitamin B, pyroxidine, amitriptyline and mannitol. Mannitol treatment is 250 cc 20% Mannitol (1mg/kg), this usually relieves the neurological symptoms in minutes and the rest of the symptoms in 3 days.
