BACKGROUND: Non-immediate reactions to beta-lactam antibiotics (BL) occur more
than one hour after drug administration, and the most common manifestations are
maculopapular exanthemas and delayed-appearing urticaria and/or angioedema.
Infections can lead to skin eruptions and mimic drug hypersensitivity reactions
(DHR), if a drug is taken at the same time. The most of children are labeled as
'drug allergic' after considering only the clinical history. OBJECTIVE: To
diagnose/detect a hypersensitivity or an infection which mimic DHR in children
with non-immediate reactions to BL METHODS: A prospective survey was conducted in
a group of 1026 children with histories of non-immediate reactions to BL by
performing patch tests, skin tests, and in case of negative results, drug
provocation tests (DPTs). In 300 children, a study was performed to detect
infections by viruses or Mycoplasma pneumoniae. RESULTS: Urticaria and
maculopapular exanthemas were the most reported non-immediate reactions. Only 76
(7.4%) of 1026 children had confirmed non-immediate hypersensitivity reactions to
BL. Fifty-seven children had positive delayed-reading intradermal tests (18 of
these with a positive patch test). Nineteen children had positive DPT. Sixty-six
of 300 children had positive tests for viruses or Mycoplasma pneumoniae and 2 of
them had a positive allergy work-up. CONCLUSIONS: A diagnostic work-up should be
performed in all children with non-immediate reactions to BL, to remove a false
label of hypersensitivity. Even though only 57 (5.5%) of 1026 children displayed
positive responses to delayed-reading intradermal tests to BL, such tests appear
to be useful in order to reduce the risk for positive DPTs.
