Background/Objectives: Kidney transplantation is the standard of care for the majority of patients with end-stage kidney disease. Neurological complications are common, and among them, tremor is very frequent and usually attributed to immunosuppressive drug toxicity. Methods: In this retrospective study, we investigate the incidence and characteristics of tremor in kidney transplant patients and analyze its occurrence with respect to a multitude of demographic and clinical parameters, thereby aiming to confirm the role of calcineurin inhibitor-induced neurotoxicity and to identify other putative predictive factors. Furthermore, we characterize post-transplant tremor with the goal of identifying its clinical features and determining the impact on quality of life. Results: A total of 129 kidney transplant recipients were screened; six patients were excluded due to a history of movement disorders prior to kidney transplantation. In total, 123 patients were included in the final analysis—69 male (56%) and 54 female patients (44%), with a median age of 50. A total of 36% (46 patients) developed tremor in the post-transplant period. Using both univariable and multivariable analyses, we found that female sex and tacrolimus use were independently associated with the development of post-transplant tremor. In addition, multivariable analysis identified an association between younger age and post-transplant tremor. Furthermore, we observed a trend in the duration of symptoms in relation to the calcineurin inhibitor choice. Conclusions: Despite a relatively high prevalence (36%), post-transplant tremor does not significantly impact the QoL and spontaneously resolves within 1 year in adult kidney transplant recipients. Female sex and tacrolimus were identified as independent predictors of post-transplant tremor in renal transplant recipients.
