Liver transplantation is a well-established treatment for liver failure. Prolongation in survival is accepted, but long-term effects of liver transplantation on cognitive and psychological outcome are unclear. In the present study, psychological data were prospectively collected for 164 patients who were assessed for liver transplantation. Memory impairment, psychomotor slowing, anxiety, and depression were commonly observed. Severity of liver disease at assessment was significantly associated with slowing of reaction time. Memory impairment distinguished those who were not listed for transplantation because of illness severity. One year posttransplantation, follow-up data from transplant recipients showed significant improvement in most psychological domains relative to both healthy comparison participants and patients with chronic liver disease who did not undergo transplantation. Immunosuppression (cyclosporine versus tacrolimus) did not have differential effects on quality of life, fatigue, or affective status, although those administered cyclosporine showed greater improvements at 1-year follow-up on simple and choice reaction times. Elevated levels of anxiety and neuroticism at pretransplantation assessment were associated with worse psychosocial outcome at 1 year posttransplantation. Severity of liver disease was not related to psychological outcome at 1 year. Good psychological outcome at 1 year was maintained at the 3-year follow-up. (Liver Transpl 2003;9:712-720.)
The World Health Organization has recently produced a generic quality of life measure--the WHOQOL-100, together with an abbreviated version, the WHOQOL-BREF. Preliminary data suggest that the WHOQOL BREF provides a valid and reliable alternative to the lengthier WHOQOL-100. In the present study, the sensitivity to change of both versions was tested pre- and 3 months post liver transplantation in fifty patients and also in twenty-one non-transplanted liver disease controls. Quality of Life domains on both measures were highly correlated, and were sensitive to change following transplant and remained stable on repeat assessment in non-transplanted control patients. However, the sensitivity to change was significantly reduced for the Social domain in the WHOQOL BREF. It is concluded that the WHO-QOL-BREF is a useful alternative to the WHOQOL-100 in evaluating quality of life improvement following major therapeutic interventions for Physical, Psychological and Environmental domains of life quality. However, researchers interested in measuring the Social aspects of life quality may be best advised to use the lengthier WHOQOL-100.
PTSD in a sample of patients who survived life-threatening variceal haemorrhage is much rarer than might reasonably have been anticipated. Possible reasons for this low prevalence of PTSD are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
