Prevalence of chronic hepatitis B and C in psoriasis patients: A cross-sectional study in a large US population

To the Editor: An association between psoriasis and hepatitis B and C is inconsistently reported in the literature.1-3 Because both hepatitis B and C viruses have been hypothesized to exacerbate psoriasis and because biologic treatments for psoriasis may be contraindicated in patients infected with hepatitis viruses, exploring this possible relationship for each virus may lead to better management.1 Consequently, this study aimed to determine the prevalence of hepatitis B and C in patients with psoriasis within a large, single-center, US patient population.
