Anaphylaxis to Polyvinylpyrrolidone in Povidone-Iodine for Impetigo Contagiosum in a Boy with Atopic Dermatitis

Abstract

This observation was in line with the clinical findings that anaphylaxis had not developed despite the long use of PVP-I solution, but developed only when he received PVP-I solution treatment where basophils could contact PVP-I in the presence of serum, which was probably due to a broken skin and vessel condition. Furthermore, our results suggest the usefulness of HRT in the diagnosis of PVP allergy, and the possibility that negative SPT does not entirely rule out PVP allergy.
