Abstract

Introduction

Russula subnigricans is now one of the leading lethal mushroom species in China, with a mortality rate of more than 50%. The typical clinical manifestation of Russula subnigricans poisoning is rhabdomyolysis, and we are unaware of previous reports of Russula subnigricans-associated hemolysis.

Case series

Herein we report a cluster of five patients with confirmed Russula subnigricans poisoning. Four of the patients who ingested sun-dried Russula subnigricans never developed rhabdomyolysis. However, in one patient, acute hemolysis developed on the second day following ingestion and was associated with a fall in hemoglobin concentration and a rise in unconjugated bilirubin concentration. Further investigation revealed that the patient had glucose-6-phosphate dehydrogenase deficiency.

Conclusion

This case cluster suggests that the toxin of Russula subnigricans could cause hemolysis in a susceptible patient and warrants further study.
