Depression during interferon therapy for chronic viral hepatitis: early identification of patients at risk by means of a computerized test.
OBJECTIVE
At the doses used for the treatment of chronic viral hepatitis, interferon (IFN)-related side-effects are usually modest, even though in some cases they require the interruption of therapy. Neuropsychiatric disturbances that range from modest depression and irritability to forms of manic-depressive psychosis and attempted or successful suicides are among the most important side-effects. The aim of our study was to determine whether the Minnesota Multiphasic Personality Inventory (MMPI) is a sensitive and reliable test for the early identification of patients at risk of depression before IFN therapy is commenced, and whether it could be useful for the monitoring of these patients during treatment.


METHODS
We prospectively studied 67 patients with chronic active liver diseases, consecutively enrolled in open studies and treated with r-IFNalpha2. Before starting therapy and after 3 months of treatment, all patients underwent a clinical neurological evaluation and MMPI.


RESULTS
At baseline, the correlation between the clinical evaluation and the score of the depression scale of the MMPI was statistically significant (P< 0.0001). Nine of 14 (64.3%) patients with a baseline score > or = 60/100 showed a depressive mood after 3 months of therapy. Five of 44 patients (11.3%) with a baseline score < 60/100 showed a depression of medium level after 3 months of treatment. This difference was highly significant (P< 0.0001).


CONCLUSIONS
According to our results, the MMPI is a reliable and sensitive test for the early identification of patients at risk of depression before and during IFN therapy for chronic viral liver diseases.
