Relationship between restless leg syndrome and quality of life in uremic patients

Patients with RLS suffer nonrestorative sleep, daytime sleepiness, fatigue, and concentration problems. In addition, dialysis itself effects the psychological and social life of the patient negatively. The aim of this study was to determine the prevalence of RLS in patients on regular hemodialysis, and its relationship with patients' quality of life, socio-demographic and laboratory data.

One hundred and eighteen stable chronic hemodialysis (HD) patients referring to the hemodialysis unit of Turkish Kidney Foundation and 49 patients that met IRLSSG diagnostic criteria were included into the study. IRLSSG Diagnostic Criteria and International Restless Leg Syndrome rating scale were used as a guideline to diagnose and evaluate the severity of RLS. Short form-36 health survey was used to evaluate the quality of life. For statistical analysis, the "SPSS for Windows" package program was used.

A total of forty-nine patients, of whom 26 were female and 23 were male, that met IRLSSG diagnostic criteria were included into the study. Mean age of the patients was 61.35 ± 13.17 years. There was a negative correlation between the IRLSS score and SF36 Physical Score, Mental Score and Total Score, respectively (p=0.018 r=-0.351, p=0.01 r=-0.380, p=0.00 r=-0.499). There was no significant correlation between the IRLSS score and dialysis duration, blood ferritin and parathyroid hormone and other comorbid diseases.

RLS is a common distressing problem in patients with ESRD, which negatively impacts functional health status. Clinicians should be aware of the symptoms of RLS to decrease morbidities related with quality of life.
