Abstract
Kidney transplantation provides the best outcome for patients with end-stage renal failure both in terms of morbidity and mortality and health-related quality of life (QoL). Health-related QoL has become recognized as an important outcome measure in patients with different chronic medical conditions, including chronic kidney disease (CKD). There are several factors in kidney-transplanted patients which have a negative impact on QoL in these patients. Sleep disorders, such as insomnia, sleep apnea syndrome (SAS), and restless legs syndrome (RLS), are common in kidney-transplanted patients and clearly belong to this group of factors, although there is only limited published data available about the association between sleep problems and QoL in this patient population. The prevalence of both insomnia and RLS is reduced in kidney-transplanted patients compared to dialysis patients, and it is similar to the prevalence observed in the general population. The prevalence of sleep apnea, however, is very high, around 30%. The association between the presence of these sleep disorders and impaired QoL has been relatively well documented in dialysis patients, but there is only scarce published information about this association in the kidney transplant population. In this paper, we will summarize data from the literature describing the impact of sleep problems, which are potentially treatable, on QoL in kidney-transplanted patients. We suggest that the appropriate diagnosis and management of sleep disorders may improve QoL in kidney-transplanted patients.
