¡¡¡¡Abstract£º¡¡Objective To analyze the expression of anti nuclear antibody spectrum(LIA-ANAs)in patients with chronic hepatitis C and to explore the clinical significance of autoantibodies in patients with chronic hepatitis C.Methods In the retrospective study,81 patients with chronic hepatitis C were selected from the outpatients and inpatients in the Department of Infectious Diseases of Changhai Hospital of Naval Military Medical University from March to July 2018 as the chronic hepatitis C group,and 81 cases from physical examination healthy people were selected as the healthy control group,and the results of LIA-ANAs,hepatitis C virus(HCV)-RNA load and liver function were measured and analyzed statistically.Results The positive rate of LIA-ANAs was 45.67%,which was significantly higher than that of the control group(4.93%,4/81),the difference was statistically significant(χ2=33.300,P<0.001).One specific autoantibody was detected in 30 cases(37.04%),which accounted for 81.08% of the patients with positive LIA-ANAs;two specific autoantibodies were detected in 6 cases(7.40%),which accounted for 16.21% of the patients with positive LIA-ANAs;three specific autoantibodies were detected in 1 case(1.23%),which accounted for 2.70% of the patients with positive LIA-ANAs.Among 81 patients with chronic hepatitis C,6 patients had ana titer≥1¡Ã100,24 patients had HCV-RNA≥1×103 copies/mL.There was a significant difference in HCV-RNA load between the positive and negative groups(χ2=4.645,P<0.05).The median difference in ALT and AST between the two groups was statistically significant,the levels of ALT and AST in the positive group were higher than those in the negative group(U=595.000,597.500,P=0.038 2,0.040 3).There was no significant difference in age(t=0.720,P=0.479)and gender(χ2=0.400,P=0.520)between the positive and negative groups of LIA-ANAs in 81 patients with chronic hepatitis C.Conclusion Patients with chronic hepatitis C are prone to produce autoantibodies.The production of autoantibodies is not related to gender and age,but related to liver function(ALT,AST)and HCV-RNA load.The detection of LIA-ANAs in sera of patients with chronic hepatitis C will be helpful for clinical diagnosis and treatment.
