This is a long-term evaluation follow-up study of neurocognitive performance and emotional state in patients with chronic hepatitis C infection and a former (peg)interferon alfa-2b-based therapy.

M.R. Kraus, G. Teuber, NN, NN (MPsych), M. Scheurlen


  • Neurocognitive and psychiatric changes induced by interferon alfa-2b therapy in patients with chronic hepatitis C - are they fully reversible in long-term follow-up after the end of antiviral treatment?
  • At least 12 months after the end of antiviral treatment - are neurocognitive and mood-related parameters even significantly improved as compared to pretreatment values? Is this possibly only true of patients with successful virus eradication?
  • At least 12 months after the end of antiviral treatment, is there a significant difference between patients with and without sustained virological response with respect to neurocognitive performance, emotional state and quality of life?
  • In the absence of clinically significant liver damage in patients with chronic hepatitis C - does the mere presence of the hepatitis C virus have any significant influence on neurocognitive or attentional performance?
  • Does the study data support an additional indication for antiviral therapy in chronic hepatitis C? In the case of successful virus eradication, emotional state and - above all - is neurocognitive performance significantly improved even in the absence of severe liver damage?

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
HCV outpatients (University Hospital)

Inclusion Criteria:

  • Patients with chronic hepatitis C and indication for interferon-based antiviral therapy.
  • Written informed consent to study participation, especially to long-term follow-up monitoring of psychiatric and neurocognitive side effects of combination therapy with (peg)interferon alfa-2b and ribavirin.
  • Age of study participants: between 18 and 65 years.
  • All patients need to have documented antibodies to hepatitis C virus (HCV) and circulating HCV-RNA as measured by reverse-transcription polymerase chain reaction (Cobas Amplicor HCV Monitor™ test, Roche Diagnostics)

Exclusion Criteria:

  • Insufficient knowledge of the German language or cognitive impairment (due to the indispensable application of questionnaires and the TAP, test battery of attentional performance).

Further Exclusion Criteria:

  • Age under 18 years or over 65 years
  • Coinfections such as hepatitis B virus or human immunodeficiency virus
  • Severe internal diseases (e.g., cancer, ischemic heart disease, autoimmune disease)
  • Major depressive disorder (according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM-IV] criteria), psychosis, active intravenous drug use or alcohol abuse.

These additional exclusion criteria are important in order to avoid interfering or confounding effects by other variables that are not linked to the hepatitis C infection.
