A Case Study: Rare Lepiota brunneoincarnata Poisoning

Abstract

Amatoxin poisoning from the genus Lepiota may have a deadly outcome, although this is not seen as often as it is from the genus Amanita. In this report, we present a patient who was poisoned by a sublethal dose of Lepiota brunneoincarnata mushrooms. The patient was hospitalized 12 hours after eating the mushrooms. The patient's transaminase levels increased dramatically starting on day 4. Aspartate transaminase peaked at 78 hours. Starting at 1265 IU/L, alanine transaminase peaked at 90 hours at 5124 IU/L. The patient was discharged on day 8 to outpatient care, and his transaminase levels returned to normal ranges in the subsequent days. A toxin analysis was carried out on the mushrooms that the patient claimed to have eaten. Using reversed-phase high-performance liquid chromatography analysis, an uptake of approximately 19.9 mg of amatoxin from. nearly 30 g of mushrooms was calculated. This consisted of 10.59 mg of alpha-amanitin, 9.18 mg of beta-amanitin, and 0.16 mg of gamma-amanitin In conclusion, we present a patient from Turkey who was poisoned by L. brunneoincamata mushrooms.
