Abstract : Background: Hepatitis C virus (HCV) and HIV infections are associated with higher risk of autoimmune diseases and T-cell dysfunction. Setting: We evaluate prevalence and factors associated with the presence of autoimmune antinuclear (ANA), anti–smooth muscle actin (aSMA), and anti–liver kidney microsome (aLKM1) antibodies (Ab) in HCV/HIV-coinfected patients during the post–combined antiretroviral therapy era. Methods: A cross-sectional observational study nested in the ANRS CO13 HEPAVIH cohort (NCT number: NCT03324633). We selected patients with both ANA testing and T-cell immunophenotyping determination during the cohort follow-up and collected aLKM1 and aSMA data when available. Logistic regression models were built to determine factors associated with the presence of auto-Ab. Results: Two hundred twenty-three HCV/HIV-coinfected patients fulfilled selection criteria. Prevalence of ANA and aSMA was 43.5% and 23.2%, respectively, and both were detected in 13.3% of patients. Isolated aSMA were detected in 9.9% and aLKM1 in 2 patients. In multivariable analysis, only a low nadir CD4 T-cell count was significantly associated with ANA detection. Conclusions: ANA and aSMA detection remain frequent in HCV/HIV-coinfected patients during the post–combined antiretroviral therapy era, despite fair immune restoration. These results advocate for a close monitoring of ANA before immune checkpoint inhibitor therapy in these patients with greater caution for those with a low nadir CD4 T-cell count.
