ABSTRACT
Early identification of culprit drugs is crucial for the treatment and prevention of severe drug eruptions.At present,no accurate and effective methods are available for identifying the culprit drugs in severe drug eruptions.Commonly used tests include patch test,lymphocyte transformation test and so on.However,low sensitivity and specificity limit their clinical application.Enzyme-linked immunospot assay,an in vitro technique,can identify culprit drugs in cutaneous adverse drug reactions by detecting cytokines secreted by drug-specific T lymphocytes.It has high sensitivity and specificity in patients with severe drug eruptions,and can be carried out during the acute stage of disease or among immunocompromised patients.Therefore,enzyme-linked immunospot assay may be an effective method for identifying culprit drugs in severe drug eruptions.
