TREATMENT OF TOAD VENOM POISONING WITH DIGOXIN-SPECIFIC FAB FRAGMENTS

Toxicity from toad venom poisoning is similar to digoxin toxicity and carries a high mortality rate. We report on six previously healthy men who developed vomiting and bradycardia after ingesting a purported to pical aphrodisiac. Each patient had positive apparent digoxin levels a nd the first four patients died of cardiac dysrhythmias. The last two patients recovered following treatment with digoxin Fab fragments. We analyzed samples of the purported aphrodisiac and found that it was id entical to Chan Su, a Chinese medication made from toad venom. to our knowledge, this is the first reported use of digoxin Fab fragments to treat toad venom poisoning.
