Hepatitis C testing and infection rates in bipolar patients with and without comorbid substance use disorders

Patients with BD and comorbid SUD had an over fourfold increase in relative risk for HCV than our control group and a similar risk as patients in our SUD group. Furthermore, even if bipolar patients did not have a comorbid SUD (the BD group), their relative risk of HCV was significantly higher than that of the control group. This suggests that patients with BD, particularly those with a comorbid SUD, should be screened and tested for HCV.
