Direct acting antivirals (DAA) result in high rates of sustained virologic response (SVR), with minimal side-effects. We assessed the impact of SVR on presence of depressive symptoms in the HIV-HCV co-infected population in Canada during the second-generation DAA era (2013-2020). Methods: We used data from the Canadian Co-infection Cohort (CCC), a multicentre prospective cohort of people with a HIV and HCV co-infection, and its associated sub-study on food security. Since depression screening was performed only in the sub-study, we predicted Center for Epidemiologic Studies Depression Scale-10 classes in the CCC using a random forest classifier and corrected for misclassification. We included participants who achieved SVR and fit a segmented modified Poisson model using an interrupted time series design, adjusting for time-varying confounders. Results: We included 470 participants; 58% had predicted depressive symptoms at baseline. The median follow-up was 2.4 years (IQR: 1.0-4.5.) pre-SVR and 1.4 years (IQR: 0.6-2.5) post-SVR. The pre-SVR trend suggested depressive symptoms changed little over time, with no immediate level change at SVR. However, post-SVR trends showed a reduction of 5% per year (risk ratio: 0.95 (95%CI: 0.94-0.96)) in the prevalence of depressive symptoms. Conclusions: In the DAA era, predicted depressive symptoms declined over time following SVR. These improvements reflect possible changes in biological pathways and/or better general health.
