Abstract: Objective To analyze the detection results of HLA-B*5801 and clinical applicability of allopurinol in our hospital in order to provide information for preventing allopurinol-caused adverse reactions. Methods The clinical information about patients who had their HLA-B*5801 detected between January 1, and December 31, 2017 in our hospital was retrospectively analyzed. The applicability of gene detection results was assessed. Results A total of 55 patients who had received gene detection were collected, including 39 from the Department of Nephrology, 13 from the Department of Dermatology, and 3 from the Department of Endocrinology. There were 17 (30.91%) HLA-B*5801 allele positive cases,38 (69.09%) negative cases. Thirteen patients suffered from cutaneous adverse reactions after allopurinol treatment, eleven of whom were HLA-B*5801 allele positive and 2 were negative. Among these patients, 30 (54.55%) had had their HLA-B*5801 gene tested before allopurinol therapy according to the guidelines. Conclusion The proportion of patients who have their HLA-B*5801 gene detected before allopurinol therapy in our hospital is relatively low. The pharmaceutical department should strengthen the supervision of clinical use of allopurinol. It is recommended that this drug be used according to the results of gene test to minimize the risk of adverse reactions.
