Penicillin allergy rashes in children misdiagnosed
Skin rashes in children though to be caused by an allergic reaction to penicillin may instead have been caused by a virus, according to scientists.
A study of 88 children who were being treated with beta-lactams and had developed delayed onset urticarial or maculopapular rashes found that around two-thirds were infected with some type of virus.
Two months after presenting at the emergency ward, further tests found that less than 7% of these children were allergic to penicillin.
As a result of their research, the Swiss scientists concluded that oral challenge tests are the best method of diagnosing penicillin allergies in children.
