ABSTRACT
OBJECTIVE:To investigate the relationship between HLA-B*5801 gene polymorphism and allopurinol-induced ADR in the Han population of Hainan Province. METHODS:The in-situ hybridization fluorescence staining analysis technique was used to detect HLA-B*5801 allele of 149 inpatients receiving allopurinol in Hainan Provincial People's Hospital during Sept. 2015-Sept. 2017.They were divided into tolerance group and ADR group according to ADR.Woolf's formula was used to calculate OR. The correlation of HLA-B*5801 allele with the occurrence of allopurinol-induced ADR was analyzed. RESULTS:Of 149 patients,there were 133 cases in tolerance group,among which 17.29%(23/133)carried HLA-B*5801 allele.There were 16 cases in ADR group,among which 93.75%(15/16)carried HLA-B*5801 allele. Among 16 ADR patients,13 patients suffered from lesion of skin and its appendents;1 patient suffered from systemic damage;1 patient suffered from gastrointestinal systemic damage;1 patient suffered from central and peripheral nervous system damage. The risk of ADR in patients with HLA-B*5801 allele was significantly higher than patients without HLA-B*5801 allele(OR:71.74,95%CI:9.02-570.55,P<0.000). The lesion of skin and its appendents was strongly associated with HLA-B*5801 allele(OR:57.39,95%CI:7.11-463.50,P<0.000). CONCLUSIONS:HLA-B*5801 allele is strongly associated with allopurinol-induced ADR. It is suggested that HLA-B*5801 allele of Han patients should be detected before taking allopurinol,which helps to reduce the incidence of allopurinol-induced ADR.
