Conclusions
There were few confirmed cases of either type of reaction. Skin testing
proved less valuable in nonimmediate reactions, over half of which would
also have been lost in a short DPT protocol. Selective responders to
amoxicillin were more likely to have nonimmediate reactions, while
clavulanic acid-selectivity was exclusive to the nonimmediate typology.
Over half the cases with DPTs required 6-7 days of treatment for DHR
confirmation.
Key words: hypersensitivity, betalactams, immediate reaction,
nonimmediate reactions, children.
