Update on Non-immediate Drug Allergy Reactions: State and New Aspects
Author(s): Enrique Gomez* and Natalia Blanca-Lopez
Purpose of the review: Among the Adverse Drug Reactions (ADR), around 10-15% are driven by an immunological
mechanism and considered as allergic drug reactions. Within the Type IV of drug allergic reactions and in accordance
with Gell and Coombs classification, the non-immediate drug hypersensitivity reactions (NI-DHR) relates to the
most complex group of drug allergy, being cellular mediated responses and appearing from 1 hour to several weeks
after drug/metabolites exposure. Current diagnosis protocols are limited and there is an unmet need to identify
a diagnostic approach that mimic the pathological response and enhance the possibilities for a more accurate and
realistic diagnosis.
Recent findings: Changes in gene patterns induced during the acute phase of the NI-DHR provide clues of the
underlying immunologica.. View more»
