Background: Mood disorders and other neuropsychiatric disorders are common adverse events limiting tolerability of alpha-interferon (IFN) therapy for hepatitis C virus (HCV). Because efavirenz (EFV) frequently produces neuropsychiatric side effects, we studied the effect of EFV in the incidence of these side effects in HIV/HCV patients receiving IFN. Methods: Prospective cohort of HIV/HCV patients receiving IFN and ribavirin. Adverse events and concomitant medications were systematically recorded once monthly. Results: Among 266 HIV/HCV patients starting a Course of IFN (91% pegylated IFN) plus ribavirin, 53 (20%) received concomitant EFV and 213 (80%) did not. Most EFV patients (92%) were already on EFV before starting IFN (mean 26 months). Neuropsychiatric side effects were frequent, without significant differences between both groups (79% vs 65%, P = 0.051), and only 10 patients discontinued IFN. Mood disorders were reported more frequently in EFV patients (36% vs 23%, P = 0.046), but antidepressant therapy use was similar in both groups. The incidence of anxiety, insomnia.. irritability, headache or prescription of anxiolytics or hypnotics was similar. Conclusions: Neuropsychiatric adverse events are common in HIV/HCV patients receiving IFN, usually mild or moderate. EFV may favor symptoms of mood disorders, although it was not related to an increased risk of significant depression requiring specific treatment.
