Psychiatric differences between liver transplant candidates with familial amyloid polyneuropathy and those with alcoholic liver disease.

BACKGROUND Psychiatric diagnoses are very common in liver transplant candidates, and such diagnoses are predictive of a poor clinical evolution and quality of life after transplantation. Also, nonadherence before the transplant is predictive of nonadherence after the transplant. METHODS We studied the psychiatric and psychosocial profiles of 85 liver transplant candidates, comprising consecutive patients attending outpatient clinics of a liver transplantation unit at a public hospital. Interviews and questionnaires were used to measure personality traits, symptoms of anxiety and depression, social support, and adherence. These patients were broken into 3 groups: patients with familial amyloid polyneuropathy (n = 20), patients with alcoholic liver disease (n = 33), and patients with other liver diseases (n = 32). RESULTS About 58% of patients had a current psychiatric diagnosis (24.8%, major depressive disorder, 22.3% generalized anxiety disorder, 8.3% adaptive disorder, 2.3% abuse of or dependence on substances other than alcohol). Current psychiatric diagnosis did not differ between patients with familial amyloid polyneuropathy and patients with alcoholic liver disease. Patients with alcoholic liver disease showed lower scores for 2 protective personality traits, social support and adherence to medication, than other patients. Patients with familial amyloid polyneuropathy showed higher scores for those traits. CONCLUSIONS All patients waiting for a liver transplant should undergo psychiatric and psychological assessment. Some psychological characteristics such as personality traits and social support differ between clinical groups, so it may be useful to design different approaches for each group. Patients with alcoholic liver disease may require a special approach to improve adherence to medication.
