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: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
