Quality of life after liver transplantation

Quality of life (QoL) is an outcome criterion of increasing importance after orthotopic liver transplantation (OLT). The background of this development is the dramatic improvement in patient survival rates over the past two decades combined with the question of the quality of this survival. Among 339 OLT performed in Kiel since 1987, 123 recipients (70 males, 53 females) of mean age 56.7 +/- 13.1 years who underwent transplantation between August 1992 and June 2007 were subjected to European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) C30 plus a liver transplant specific module to analyze QoL. In addition, we included 40 patients listed for OLT in the univariate and multivariate analyses performed using SPSS13.0. A cohort of healthy individuals served as the control group. QoL (global health) among liver recipients was reduced compared with the control group and improved compared with patients on the waiting list. Comparison of the underlying liver diseases showed a comparable QoL between postalcoholic cirrhosis and cholestatic liver diseases. Retransplantation was accompanied by a significant loss of QoL. Cyclosporine-treated recipients displayed a better QoL compared with those treated with tacrolimus. After establishing a system of continuous, systematic QoL assessment, we combined these results with survival outcomes. Further research must focus on advanced statistical methodology that combines these 2 major outcome parameters (QoL and survival). Furthermore, the influence of medical parameters, such of co-morbidity or immunosuppression, needs to be further established with reference to QoL.
