Determinants Of Stigma Among Patients With Hepatitis C Virus (HCV) Infection

Abstract [from journal]

Stigma around hepatitis C virus (HCV) infection is an important and understudied barrier to HCV treatment and elimination. The determinants of HCV-related stigma, including the impacts of stage of HCV treatment (i.e., spontaneously-cleared; diagnosed, untreated; previously treated, not cured; currently being treated; treated, cured) and coinfection with human immunodeficiency virus (HIV), remain unknown. To address these gaps, we conducted a cross-sectional study among patients with a history of HCV infection (n=270) at outpatient clinics in Philadelphia from July 2018 - May 2019. We evaluated stigma using the validated HCV Stigma Scale, adapted from the Berger HIV Stigma Scale. Associations among HCV-related stigma and hypothesized demographic, behavioral, and clinical risk factors were evaluated by multivariable linear regression. Most participants (95.5%) experienced HCV-related stigma. Mean stigma scores did not differ significantly between HCV-monoinfected and HIV/HCV-coinfected participants (P=0.574). However, we observed significant interactions between HIV status and multiple determinants; therefore, we stratified analyses by HIV status. Among HIV/HCV-coinfected participants, previous HCV treatment without cure, female gender, Hispanic/Latino ethnicity, and some college education were significantly associated with higher HCV-stigma scores. An annual income of $10,000-$40,000 was associated with significantly lower stigma scores. No significant associations were observed among HCV-monoinfected participants. We found that most participants experienced stigma associated with HCV diagnosis. While stigma scores were similar between HCV-monoinfected and HIV/HCV-coinfected participants, the determinants associated with HCV stigma differed by HIV status. Understanding how experiences of stigma differs between HCV-monoinfected and HIV/HCV-coinfected patients may aid in the development of targeted interventions to address the HCV epidemic.
