Neuropsychiatric Effects of Interferon-Alpha and Ribavirin

Completed

Conditions studied: Mental Disorder

In brief

Use of the drug interferon-alpha (IFN-A), is associated with frequent and well characterized side effects like neurotoxicity. Neurotoxicity can cause symptoms of depression, agitation, anxiety, and/or confusion. The NIDDK is conducting a research study called, "Combination of Alpha Interferon with Long Term Ribavirin Therapy for Patients with Chronic Hepatitis C" (98-DK-0003). Patients participating in it are receiving interferon-alpha in addition to an antiviral medication called ribavirin. Researchers at the NIMH intend to study patients to learn more about how different medications can influence mood, thoughts and behavior. The primary purpose of this study is to determine if treatment with IFN-A in combination with ribavirin alters human brain biochemistry as measured by proton magnetic resonance spectroscopy (MRS). MRS uses strong magnetic fields in order to measure biochemical products of metabolism found in the brain. Researchers intend to perform MRS scans before, during, and after patients receive their medications Researchers believe that the combination of IFN-A/Ribavirin will directly affect specific areas of the brain and as a result, some patients will develop specific mood or cognitive symptoms. Patients often must stop taking these medications because of the side effects. This study will not contribute directly to the treatment of patient's Hepatitis C condition. However, the information gathered from this study will help researchers better understand the neuropsychiatric affects associated with interferon alpha and ribavirin therapy.
