Tremors and Health-Related Quality of Life in Liver Transplant Recipients: Post-hoc Analysis of a Multicenter, Randomized, Controlled Trial Comparing a Life Cycle Pharma-Tacrolimus Regimen and Extended-Release Tacrolimus Regimen

We investigated whether life cycle pharma (LCP)-tacrolimus compared to extended-release (ER)-tacrolimus results in a difference in severity of tremors and HRQoL. In this multi-center, open-label, randomized, controlled trial, 108 patients were randomized in a 1:1 ratio to either LCP-tacrolimus regimen or ER-tacrolimus regimen after transplantation. HRQoL was assessed with the EQ-5D-5L and SF-36 questionnaire (two generic HRQoL instruments) and the quality of life in essential tremor (QUEST) questionnaire (domain specific HRQoL instrument). The EQ-5D-5L scores were translated to the societal values. We examined the HRQoL over the course of the study by fitting generalized mixed effect models. In total, 105 patients were included, 53 to the LCP- and 52 to the ER-tacrolimus regimen. Baseline questionnaires were available for every LT recipient. At 12 months 25% [10/40], 95% confidence interval (CI) 14.2%–40.2% of the LT recipients in the LCP-tacrolimus regimen group experienced tremors compared to 30.4% [14/46], 95%-CI 19.1%–44.8% of the LT recipients in the ER-tacrolimus regimen group; risk difference: 0.054; 95%-CI −0.151–0.249; p = 0.63. No statistically significant differences in HRQoL were seen between the two regimens.
