Mast Cell Anergy: absence of symptoms after accidental re-exposure to
amoxicillin/clavulanic acid 3 days after anaphylaxis
Abstract
Empty Mast Cell Syndrome, also named Post Anaphylaxis Mast Cell Anergy
(PAMA), is a temporary state of loss of mast cell responsiveness after a
severe immediate hypersensitivity reaction. We describe a case of PAMA
after accidental re-exposure to amoxicillin in a patient who developed
severe anaphylaxis to this drug three days earlier in the operating
room.
