Abstract:
Objective To study the DNA methylation of nucleated cells in peripheral blood of patients died from anaphylactic shock caused by cephalosporin drugs and to provide a new research direction and basis for the forensic diagnosis of shock caused by drug hypersensitiveness. Methods Methylation microarray was used to detect DNA methylation of nucleated cells in peripheral blood of patients died from anaphylactic shock caused by cephalosporin drugs and normal subjects. Sequencing data and chip data were analyzed for differences in DNA methylation using R language methylkit, ChAMP package. Random forest algorithm was used to evaluate the importance of the DNA methylation differential sites. Results Differential sites of DNA methylation highly associated with anaphylaxis caused by cephalosporin drugs were obtained at loci such as ETS1, PRR23B and GNAS. Conclusion Cephalosporin allergy is associated with DNA methylation, and DNA methylation may be a new strategy for forensic identification of anaphylactic shock and death.
