Síndrome das pernas inquietas em unidades de hemodiálise em Manaus

Abstract

Restless legs syndrome (RLS) is a sensorimotor disorder characterized by an urge or need to move the limbs and variable discomfort. Chronic renal failure (CRF) is an important cause of secondary RLS. The aim of this study was to assess the frequency of RLS in CRF patients in a hemodialysis unit in Manaus. 57 patients with CRF were assessed. A clinical protocol was used for personal dates, medical dates, and criteria provided by International Restless Legs Syndrome Study Group. Biochemical and hematological values were obtained. The frequency of RLS was 14% (08 patients). There was not difference in hematologic and biochemical tests. The frequency is considerable and suggests an important presence of the Restless Legs Syndrome in the population of patients in hemodialysis. Further biochemical studies are necessary to elucidate the pathophysiology of RLS in patients with renal failure. Keywords: Restless Legs Syndrome, chronic renal failure.
