Mushroom poisoning: An updated review.

Area of Science:

• Mycology
• Toxicology
• Clinical Medicine

Background:

• Mushrooms are widely consumed globally, with both edible and toxic varieties.
• Distinguishing poisonous from edible mushrooms morphologically is often impossible, leading to accidental poisonings.
• Mushroom toxins cause diverse clinical syndromes, ranging from mild gastrointestinal upset to fatal outcomes.

Purpose of the Study:

• To review clinical syndromes associated with poisonous mushroom consumption.
• To elucidate the mechanisms of action of various mushroom toxins.
• To outline current therapeutic strategies for mushroom poisoning.

Main Methods:

• Literature review of clinical cases and toxicological studies.
• Categorization of mushroom toxins (e.g., cyclopeptides, gyromitrin, amatoxins).
• Analysis of the clinical manifestations and pathological mechanisms of poisoning.

Main Results:

• Cyclopeptide-amatoxins are implicated in over 90% of fatal mushroom poisonings.
• Amanita phalloides is a significant cause of lethal mushroom ingestions.
• Various toxins induce distinct clinical syndromes, necessitating specific diagnostic and treatment approaches.

Conclusions:

• Mushroom poisoning is a critical public health concern requiring accurate identification of toxic species.
• Understanding toxin mechanisms is crucial for developing effective treatments.
• Prompt medical intervention based on toxin type improves patient outcomes.
