Assessment of the Frequency of Autoantibodies in Chronic Viral Hepatitis

Abstract

Objective: To examine the occurrence frequency of auto-antibodies and autoimmune diseases in patients with chronic hepatitis B or C.

Methods: A total of 67 patients diagnosed with chronic hepatitis B and 77 patients diagnosed with chronic hepatitis C infection based on HBs Ag, Anti HCV, HBe Ag, Anti HBe Ag, HBV DNA, HCV RNA, liver ultrasound, and liver biopsy results as well as 48 healthy individuals were included in this study. ANA, anti dsDNA, anti LKM, Anti-SMA, AMA, C-ANCA, P-ANCA, anti-SSA, anti-SSB, anti-Scl-70, anti Jo-1, anti-U1snRNP, anti-centromere, anti-Jo-1, anti tpo, and anti tg were studied in all individuals in each study group.

Results: ANA positivity was detected in 8 (12%), 15 (19%) and 2 (4%) individuals in HBV, HCV and control groups, respectively. The difference between the groups was significant (P=0.04). Similarly, anti Tg was positive in one subject in HBV group, in 6 subjects (7%) in HCV group, and in one subject among controls, the difference being significant (P=0.04). There were no significant differences between the study groups in the frequency of other auto-antibodies.

Conclusion: Similar to studies involving patients who received interferon and/or antiviral agents, an increased frequency of auto-antibodies was also detected in our patient group consisting of interferon and anti-viral naive subjects. The increase in the frequency of auto-antibodies reached statistical significance among individuals with HCV infection. Thus, pre-treatment assessment of auto-antibodies in newly diagnosed cases of chronic hepatitis B or hepatitis C infection may provide beneficial information on the future occurrence of auto-immune responses in these patients.
