title: Interferon treatment is not associated with a worsening of psychiatric symptoms in patients with hepatitis C.
abstract: OBJECTIVE
  To study prospectively the psychiatric side effects of interferon-alpha in patients with hepatitis C.
  
  
  METHODS
  Sixty-three consecutive patients at a hepatitis clinic were recruited. All were assessed using a psychiatric interview (SCID) and monitored using a self-reporting psychiatric symptom questionnaire (SCL-90).
  
  
  RESULTS
  Patients on interferon did not suffer a drop in mood or an increase in anxiety or irritability. The subgroup with past depression also did not suffer an increase in depressive symptoms. No patients attempted suicide.
  
  
  CONCLUSIONS
  The risk of serious psychiatric symptoms when being treated with interferon-alpha may not be high. Psychiatric illness or the possibility of psychiatric complications should not be used as a reason to refuse this treatment to patients with hepatitis C.
