Abstract

Hepatitis C virus (HCV) infection is associated with a myriad of extrahepatic manifestations (EHM), as well as the production of autoantibodies, including rheumatoid factor (RF). This study aims to elucidate whether serum levels of RF change before and after HCV eradication, and whether these changes differ according to the type of therapy used. This is a retrospective cohort study of adults with chronic HCV infection treated with interferon-free or interferon-based regimens. All patients had HCV viremia at baseline and documented sustained virological response (SVR) 12 or 24 weeks after completing treatment. We measured the serum levels of RF at baseline and at SVR-12 or −24 to analyse the changes after eradication. This study enrolled 297 patients (median age, 59 years; female, 48.5%; cirrhosis, 16.8%). Among them, 78 (26.3%) were RF-positive by qualitative serology at baseline. This number decreased to 49 (16.5%) at SVR-12 or −24 (p < 0.001). Quantitatively, the median RF also decreased from 1.6 IU/mL (interquartile range [IQR], undetectable—15.8) to undetectable (IQR, undetectable—6.6 IU/mL) (p < 0.001). Significant reductions were observed in both groups. The proportion with RF seropositivity decreased from 24.3% to 15.4% (p = 0.001) in patients treated with interferon-free agents (n = 214) and from 31.3% to 19.3% (p = 0.006) in patients treated with interferon-based regimens (n = 83), without significant difference between two groups (p = 0.40). Serum RF decreased after HCV eradication, regardless of treatment regimen. Our findings suggest that HCV eradication may attenuate HCV-related autoimmunity.
