title: Hemoperfusion with alpha-amanitin: an in vitro study.
abstract: The authors carried out sixteen hemoperfusions with alpha-amanitin in vitro in a closed system using active charcoal, Amberlite XAD-2 and Amberlite XAD-4 in hemoperfusion capsules. As a perfusion solution 4 liters of 0.9% NaCl solution was used. The alpha-amanitin concentration in the solution was 8.3 +/- 0.36 mg/L. Individual hemoperfusion lasted 5 hours. Two hundred and forty minutes of Amberlite XAD-2 hemoperfusion led to the zero values of alpha-amanitin concentration in 0.9% NaCl solution. When using active charcoal the adsorption capacity of the hemoperfusion capsule was already exhausted at 120 min. The results gathered suggest that the most effective alpha-amanitin hemoperfusion in vitro was obtained with Amberlite XAD-2 and the least effective with active charcoal. The authors recommend the use of hemoperfusion with Amberlite XAD-2 for acute intoxication with Amanita phalloides in humans up to 24-36 hours after poisoning.
