Depression caused by common treatment for hepatitis C

==Depression caused by common treatment for hepatitis C may affect

outcomeATLANTA–An article appearing in the January 2005 issue of Brain, Behavior

and Immunity suggests that developing depression while on interferon-alpha plus

ribavirin may impact how well the medications work.

In a study conducted in the Department of Psychiatry and Behavioral Sciences at

Emory University School of Medicine, Charles L. Raison, MD, Andrew Miller, MD,

and colleagues, observed that patients who develop depressive symptoms during

interferon-alpha plus ribavirin therapy were significantly less likely to have

cleared the hepatitis C virus from their blood following six months of

treatment.

" Hepatitis C infection affects three to five million Americans, and is the

leading cause of liver transplantation, " said Dr. Raison. " With advances in

treatment, 40-50 percent of patients can be cleared of the virus. Unfortunately,

however, the current treatment for hepatitis C – interferon-alpha plus ribavirin

– produces a high rate of psychiatric side effects that have long been

recognized as impediments to successful antiviral therapy. In the past we

primarily worried that depression interfered with quality of life, or would

cause patients to stop taking the medicine. These new data suggest that even if

patients stay on treatment, they are less likely to have a good outcome if they

develop depression. "

The study examined 103 participants who received pegylated interferon-alpha-2b

plus ribavirin (PEG IFN/ribavirin). All participants were psychiatrically

evaluated prior to initiation of the medication and at 4, 8, 12 and 24 weeks of

PEG IFN/ribavirin treatment.

Only 34% of the patients who had a significant increase in depression cleared

the hepatitis C virus from their blood at 24 weeks, as compared to 59%-69% of

patients with milder increases in depression. The effect of depression on viral

clearance persisted even after adjusting for factors known to affect treatment

outcome, such as viral genotype, or whether medications had to be reduced.

" The findings of this study provide preliminary evidence that baseline mood

state should be assessed in patients prior to commencing treatment, " said Dr.

Raison. " Significant deviations from this state may increase the likelihood of

treatment failure. Moreover, these findings provide further support that the

development of depression can have a negative impact on health outcomes in

medically ill subjects. "

Researchers from the Rollins School of Public Health, Emory University and the

Department of Medicine, Gasteroenterology and Hepatology, Weill Medical College

of Cornell University were also involved in the study. The study was supported

by grants from the National Institute of Mental Health, Schering–Plough, and the

Centers for Disease Control and Prevention.
