Abstract
The association of human leukocyte antigen (HLA) with the risk of drug-induced skin eruptions has been extensively studied. The sensitivity of the association of specific HLA alleles with drug eruptions ranges from approximately 50 to 100%, indicating a significant influence of HLA alleles on the risk of developing such reactions. Consequently, HLA testing holds substantial clinical potential as a genetic diagnostic tool to avoid drug eruptions. For instance, when prescribing drugs like carbamazepine and lamotrigine, which are known to cause severe drug eruptions, preemptive HLA genetic testing can help predict an individual's risk. This approach enables clinicians to reduce the overall incidence of drug eruptions by selecting alternative therapeutic agents or adjusting dosages based on the results of HLA genetic testing.
期刊介绍：
Allergology International is the official journal of the Japanese Society of Allergology and publishes original papers dealing with the etiology, diagnosis and treatment of allergic and related diseases. Papers may include the study of methods of controlling allergic reactions, human and animal models of hypersensitivity and other aspects of basic and applied clinical allergy in its broadest sense.
The Journal aims to encourage the international exchange of results and encourages authors from all countries to submit papers in the following three categories: Original Articles, Review Articles, and Letters to the Editor.
