    Summary
    This summary is machine-generated.

    Ciguatera poisoning, caused by toxins in tropical reef fish, is increasingly found in temperate regions. Intravenous mannitol shows promise for treating this seafood toxicosis.

    Area of Science:

    • Marine Biology
    • Toxicology
    • Public Health

    Background:

    • Ciguatera poisoning is a significant health concern linked to consuming tropical coral reef fish.
    • Increased global travel and seafood importation are leading to more frequent ciguatera cases in non-endemic, temperate regions.
    • The primary cause is toxins from the dinoflagellate Gambierdiscus toxicus, potentially with bacterial involvement.

    Purpose of the Study:

    • To review the pathophysiologic features and symptoms of ciguatera poisoning.
    • To compare ciguatera with other seafood-related syndromes.
    • To discuss current and potential therapeutic interventions.

    Main Methods:

    • Literature review of ciguatera poisoning.
    • Analysis of clinical manifestations and toxicological profiles.

  • Comparison with other seafood toxicosis syndromes.

    • Main Results:

    • Ciguatera toxicosis onset ranges from 10 minutes to 30 hours post-ingestion.
    • Symptoms include gastrointestinal and neurological effects, cardiovascular changes, and prolonged fatigue.
    • Intravenous mannitol is identified as the most promising treatment, though not definitively curative.

    Conclusions:

    • Ciguatera poisoning is an emerging public health issue in temperate zones due to global food trade.
    • Early recognition of symptoms and prompt treatment are crucial for patient outcomes.
    • Physicians must educate travelers about the risks of consuming tropical reef fish.
