1680 – Prevalence, Severity And Course Of Depressive Symptomatology In Chronic Hepatitis c Patients On Pegylated Interferon Alpha: a 72-week Prospective Study

Abstract

Introduction

Treatment with pegylated interferon alpha (PEG-IFN-α) in patients with chronic hepatitis C (CHC) is associated with depression more frequently than in other diseases treated with PEG-IFN-α.

Objective

To prospectively evaluate prevalence, severity and course of depressive symptomatology in CHC patients treated with PEG-IFN-α.

Methods

Hamilton Depression Rating Scale (HAMD) was used to asses depressive symptoms in 103 subjects with CHC before PEG-IFN-α (mean dose 152.6±25.6 mcg; duration of therapy 48 weeks) and at the follow-up visits (4th, 12th, 24th, 48th, 72th week). Control group included 103 subjects with CHC without PEG-IFN-α.

Results

There was a significant increase in HAMD scores as early as in the 4th week of PEG-IFN-a therapy compared to baseline scores (38.8% vs. 24.3%). The peak of depressive symptomatology was detected in the 12th week (mean HAMD 9.34¤ 6.93), when a half of patients (49.5%) had HAMD above 7. At the end of the treatment (48th week), 38.8 % had HAMD above 7, and in the 72nd week (24 weeks without PEG-IFN-α), prevalence of depressive symptomatology was decreased to the values lower than at baseline (23.3% vs. 24.3%). The majority (28.2%) had mild depression, whereas moderate and severe depressive symptoms were found in 20.4% and 1%, respectively. No change in prevalence of depression was detected in control group.

Conclusion

Present study is the longest follow-up study of depressive symptoms as a side-effect of PEG-IFN-α in CHC. Our data yielded that the severity of the symptoms was mild to moderate and tends to decrease following therapy completion.
