#2736 THE PHASE ANGLE AS A PREDICTOR OF SARCOPENIA IN NORMOHYDRATED PATIENTS ON HEMODIALYSIS: A MULTICENTER STUDY

Abstract Background and Aims The skeletal muscle index (SMI) is an impedance parameter that assesses mass, the phase angle (PA) inversely related to strength mass in hemodialysis patients. Both parameters may represent useful inexpensive tools identify sarcopenic Method presence of sarcopenia was analyzed 348 normohydrated patients 5 centers by means vector bioimpedance using BIA101 BIVA PRO equipment. To do this, are evaluated as markers strength, respectively. Results Mean SMI PA were 8.64 ± 1.5 5.2 0.9. mean 5.6 0.9 those with within normality (9.2 1.9) (p<0.001). In moderate severe sarcopenics patients, (8.9 1.2 vs 7.5 0.9) (5.3 0.86 4.7 0.67) significantly lower (p < 0.001) (Table 1). on standard hemodialysis, (P = .02) .004) lower. .014) 0.01) female gender but number higher among men (p< 0.001). cut-off value PA, which predicted a risk sarcopenia, 3.5 all (95% CI, 0.60-0.71; P .0001; 100% sensitivity, 96% specificity ); 3.55 for 0.57-0.78; .003; 94% specificity) 3.65 women 0.60-0.73 ; (Fig. logistic regression analysis, male gender, technique, associated 2).
