Abstract
BACKGROUND: Most research on the psychiatric symptoms of peginterferon/ribavirin for the treatment of hepatitis C comes from VA centres and clinical trials with rigid entry criteria that often excluded patients with markers of mental health and substance use disturbance (MH/SUD). The findings from these lines of research may not be generalizable to patients treated under standard of care in a tertiary care setting. AIM: To investigate the incidence and outcomes of psychiatric symptoms in patients treated under standard of care protocol, not enrolled in clinical trials. METHODS: This is a retrospective analysis of 215 patients who underwent therapy from 2002 to 2006 at a university-based tertiary care centre. Survival curves explored the relationship between history of MH/SUD and the development of psychiatric symptoms on treatment. RESULTS: The cumulative history of MH/SUD was 67%. Of these, 39% had taken psychotropic medications previously, and 80% continued on them during therapy. On therapy, 46% developed depressive symptoms, 19% and 46% endorsed anxiety and irritability respectively. Cumulatively, 64% of patients indicated mood disturbance on therapy. Most symptoms developed between weeks 2 and 18, and rarely after week 20. Of those who developed mood symptoms, 66% required an intervention. Treatment discontinuation was infrequent. CONCLUSIONS: This large observational study provides important insights into the incidence and course of psychiatric symptoms in an unselected sample of patients treated in a tertiary care setting. Patients had higher rates of MH/SUD comorbidity, psychotropic medication use and exhibit higher rates of mood disturbance on therapy compared with previous reports, although a majority completed the prescribed treatment regimen.
