ABSTRACT OBJECTIVE To explore the pathogenesis, diagnosis and treatment of drug reaction with eosinophilia and systemic
symptoms (DRESS) caused by cross-allergy between cephalosporins and carbapenems, and provide reference for safe clinical
medication. METHODS Clinical pharmacists participated in the diagnosis and treatment process of a patient with severe pneumonia
whose DRESS caused by suspected cross-allergy between cephalosporins and carbapenems in our hospital. At the same time,
relevant studies on the pathogenesis, diagnosis, treatment, and cross-allergy between cephalosporins and carbapenems were
retrieved for analysis. Based on the clinical manifestations and treatment process of this patient, the possible mechanisms of cross-
allergy between cephalosporins and carbapenems and the treatment strategies for DRESS were discussed. RESULTS The
RegiSCAR score of this patient was 6 points, confirming the diagnosis of DRESS. There may be β-lactam ring-specific human
leucocyte antigen alleles or T-cell receptors, which led to suspected cross-allergic reactions between cephalosporins and
carbapenems. The clinical pharmacists suggested discontinuing cephalosporins and carbapenems and using methylprednisolone
combined with immunoglobulin for treatment. The physician adopted the pharmacist’s suggestion, and the patient did not have
fever again and the rash gradually subsided. CONCLUSIONS There is a possibility of cross-allergy between cephalosporins and
carbapenems causing DRESS. For patients with DRESS, it is recommended to promptly investigate the suspected drugs and
discontinue them. The combination of glucocorticoids and immunoglobulin is a feasible treatment option. Medical institutions with
conditions should conduct herpesvirus screening and treatment.
