Evaluation of syndrome symptons of restless legs in patients with renal dialytic failure in a southern city of Santa Catarina
Introduction: Renal failure is characterized by functional loss of the kidney and hemodialysis is the therapeutic option. The renal patient may have sleep disorders, including restless legs syndrome (RLS), which occurs in 30% of renal patients and in 10% of the general population. It is a motor neurological disorder, whose etiopathogenesis is not understood. Clinical diagnosis is the gold standard. RLS has been associated with cardiovascular morbities and increased mortality, however, it is underdiagnosed. The present study aimed to assess the prevalence and factors associated with RLS symptoms in patients with dialysis renal failure in a private clinic for chronic renal patients. Methods: Cross-sectional study, including 140 patients seen at the Tubarão Renal Diseases Clinic, from August to November 2016. Results: The average age of the interviewed population was 60.82 years, the majority being men (63.6%). Most respondents reported having restful sleep (78.6%). Despite this, snoring / sleep apnea prevalence was found in more than half of the patients (57.1%) and SPI in 19.3% (the most severe form being found in 8.6% of the patients). Other comorbidities found were: SAH, insomnia, diabetes mellitus and cardiac disorders. Statistically, dialysis time was longer among patients with RLS (P = 0.03). The female gender was shown to be a risk factor (P = 0.006) and cardiac alterations also had a significant association (P = 0.044-Fisher), as well as insomnia (p = 0.00011). Conclusions: Sleep disorders are prevalent and should be part of the assessment of all dialysis patients.
