Depression caused by common treatment for hepatitis C may affect outcome

17.01.2005


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.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
