Abstract
Background
The additional burden of HCV infection in HIV–HCV-coinfected individuals may have some consequences on adherence to HAART. Few studies have explored the pattern of correlates of non-adherence to HAART while simultaneously considering the impact of HCV treatment and depressive symptoms on adherence to HAART. We used longitudinal data to assess factors associated with non-adherence to HAART.
Methods
The French national prospective cohort ANRS-CO13-HEPAVIH is a multicentrer cohort, which recruited 1,175 HIV–HCV-coinfected patients in 17 hospital outpatient units delivering HIV and HCV care in France between October 2006 and June 2008. For this analysis, we selected participants on HAART with self-reported data for adherence to HAART (n=727 patients, 1,190 visits). Data were collected using self-administered questionnaires and medical records. A mixed logistic regression model based on an exchangeable correlation matrix was used to identify factors associated with non-adherence to HAART.
Results
Patients reported non-adherence to HAART in 808 (68%) of the 1,190 visits. Four variables remained associated with non-adherence to HAART after multivariate analysis: hazardous alcohol consumption, cocaine use and depressive symptoms, regardless of whether treatment for depression was being received. Finally, patients being treated for HCV infection were less likely to be non-adherent to HAART.
Conclusions
Besides the problem of polydrug use, two other dimensions deserve special attention when considering adherence to HAART in HIV–HCV-coinfected patients. Access to HCV treatment should be encouraged as well adequate treatment for depression in this population to improve adherence and response to HAART.
