Abstract: Objective To explore the correlation between fulminate type 1 diabetes mellitus and allopurinol-induced drug hypersensitivity syndrome, and to provide reference for clinical practice. Methods A patient with HLA-B*5801 allele who developed secondary fulminant type 1 diabetes mellitus after allopurinol-induced hypersensitivity syndrome and was reported. The characteristics of the case and the related mechanism of drug-induced adverse reactions were analyzed according to the relevant literature, and the treatment measures for such patients were sorted out. Results The patient lost islet function completely and needed long-term multiple daily insulin injection to control blood glucose in the future. Previous studies and case reports suggest that this adverse event may be related to the use of allopurinol. Conclusion This case suggests that HLA-B*5801 gene testing should be performed before allopurinol treatment. Clinicians should be aware of the risk of secondary autoimmune diseases associated with drug-induced hypersensitivity syndrome.
