Psychiatric comorbidity among hepatitis C-positive patients.

This study assessed the prevalence of psychiatric disorders among hepatitis C patients at a Veterans Affairs Medical Center. Medical records of 306 randomly selected hepatitis C-positive patients were reviewed for past and present DSM-IV-based psychiatric disorders. Each psychiatric diagnosis was independently confirmed with DSM-IV criteria using symptoms recorded in the chart. Only independently confirmed diagnoses were included for analysis. Mood disorders were present in 38% of patients; personality disorders in 30%; PTSD in 19%; other anxiety disorders in 9%; and psychotic disorders in 17%. Although alcohol use disorders were found in 86% of this patient population, intravenous drug use disorders were present in only 28%. Our data indicate that prevalence rates of a variety of psychiatric disorders are higher in veterans with hepatitis C than in the general population. Mood, anxiety, personality, and psychotic disorders were all relatively common in these patients. Psychiatric disorders may influence the course and treatment of hepatitis C infection, and psychiatrists as well as internists should be aware of the substantial psychiatric comorbidity in patients with this infection.
