Abstract

Objectives- To determine clinical and laboratory predictors of restless legs syndrome (RLS) in patients with end-stage kidney disease (ESKD) undergoing long-term hemodialysis (HD). Materials and Methods- One hundred and sixty-two consecutive patients were assessed. History of sleep disturbances, neurological examination, clinical, and laboratory data were collected. Patients with and without RLS were compared, and a logistic regression model described the relations between independent predictors and RLS. Results- Fifty-one patients (32%) currently had RLS (RLS+). RLS+ vs RLS- patients were more frequently women (49% vs 29%, P=0.012), had first-degree relative with RLS (22% vs 6%, P=0.004), insomnia (59% vs 36%, P=0.007), peripheral neuropathy (41% vs 21%, P=0.006), and low residual diuresis (92% vs 68% with below 500ml/24h, P=0.001). Low (OR=8.71, CI=2.27-33.41; P=0.002) and absent (OR=4.96, CI=1.52-16.20; P=0.008) residual diuresis, peripheral neuropathy (OR=4.00, CI=1.44-11.14; P=0.008), and first-degree relative with RLS (OR=3.82, CI=1.21-12.13; P=0.023) significantly predicted RLS in ESKD patients undergoing HD. Conclusion- Positive family history for RLS together with reduced/absent residual renal function and peripheral neuropathy predicts the risk for RLS in ESKD patients undergoing HD. Longitudinal studies are warranted to correlate RLS occurrence with genetic and environmental factors.
