				        	Objective To investigate the correlation between human leucocyte antigen-DQA1(HLA-DQA1)and clinical characteristics of patients with Sj?gren's syndrome(SS).Methods A total of 242 SS patients admitted to the First Affiliated Hospital of Baotou Medical College from August 2022 to August 2023 were selected as the study objects.According to the HLA-DQA1 test results,the patients were divided into HLA-DQA1 positive group(n=147)and HLA-DQA1 negative group(n=95).The clinical manifestations,laboratory indicators,labial gland biopsy and disease activity were compared between two groups.Receiver operating characteristic curve was used to analyze the diagnostic value of HLA-DQA1 for disease activity in SS patients.Results The proportion of dry mouth,dry eye and purpura,the proportion of anti-SSA antibodies,anti-SSB antibodies,antinuclear antibody(ANA)positive and the level of immunoglobulin G in HLA-DQA1 positive group were significantly higher than those in HLA-DQA1 negative group(P<0.05),and the hemoglobin level was significantly lower than that in HLA-DQA1 negative group(P<0.05).The disease activity of HLA-DQA1 positive group was significantly higher than that of HLA-DQA1 negative group(P<0.05).The areas under the curve of HLA-DQA1,anti-SSA antibody and anti-SSB antibody to determine the disease activity of SS patients were 0.593,0.534 and 0.593,respectively.The area under the curve of disease activity of SS patients judged by the three indexes combined was 0.638.Conclusion HLA-DQA1 is correlated with the disease activity of SS patients.In HLA-DQA1 positive patients,dry mouth,dry eyes,hyperglobulinemia,anemia and purpura were more obvious.Meanwhile,the positive rates of anti-SSA/SSB antibodies and ANA were higher,suggesting that HLA-DQA1 expression is helpful in judging the disease of SS patients.
