[Hemolysis in mushroom poisoning: facts and hypotheses]
Abstract:
Primary hemolysis induced by antigens and toxins of mushrooms must be distinguished from hemolysis secondary to shock and disseminated intravascular coagulation with disruption of erythrocytes caused by severe poisoning with many mushroom species. Primary hemolysis is well documented as immunohemolysis after repeated ingestion of involute paxillus (Paxillus involutus). Direct hemolysis is reported after eating raw mushrooms with a high content of hemolysins. Hemolysis is only speculative in monomethylhydrazine poisoning by false morels (Gyromitra esculenta). Secondary hemolysis due to shock is not uncommon. Hemolysis in connection with enzymopenia of erythrocytes has not been documented as yet. In the present study the various hemolytic syndromes are described and discussed.
Insights
Mushroom poisoning can cause primary hemolysis from toxins or secondary hemolysis from shock. This study differentiates these hemolytic syndromes, including immunohemolysis and direct hemolysis, for better understanding of mushroom-induced red blood cell damage.
Area of Science:
- Toxicology
- Hematology
- Mycology
Context:
- Mushroom ingestion can lead to various adverse health effects, including hemolysis.
- Distinguishing primary hemolysis from secondary hemolysis is crucial for accurate diagnosis and treatment.
- Previous research has documented specific instances of mushroom-induced hemolysis.
Purpose:
- To describe and discuss the various hemolytic syndromes associated with mushroom poisoning.
- To differentiate primary hemolysis (immunohemolysis, direct hemolysis) from secondary hemolysis (due to shock, disseminated intravascular coagulation).
- To review the known and speculative mechanisms of mushroom-induced hemolysis.
Summary:
- Primary hemolysis can be immunohemolytic (e.g., Paxillus involutus) or direct (raw mushrooms with hemolysins).
- Secondary hemolysis, often due to shock or disseminated intravascular coagulation, is common in severe poisoning.
- Hemolysis in monomethylhydrazine poisoning (Gyromitra esculenta) and erythrocyte enzymopenia remain speculative.
Impact:
- Provides a comprehensive overview of hemolytic syndromes in mushroom poisoning.
- Aids clinicians in differentiating causes of hemolysis in patients with suspected mushroom exposure.
- Highlights areas for future research, such as erythrocyte enzymopenia and specific toxin mechanisms.
