Even malnutrition is highly prevalent in PD patients. It is now well established that lower levels of serum markers of nutrition such as albumin, creatinine, and prealbumin are associated with increased mortality in PD patients [Fein, P.A. et al: Adv Perit Dial 2002;18:195–199]. Moreover cardiovascular disease is a leading cause of death in patients with end-stage renal disease, and hypertension and volume expansion are highly prevalent in long-term PD patients. Many studies in hemodialysis and in PD have demonstrated that phase sensitive bioelectrical impedance analysis is a widely used and proven method for evaluating patient’s body composition. The vectorial bioimped- ance analysis is a validated system to evaluate the hydration and nutritional state of hemodialysis and PD patients with acceptable sensitivity and specificity. The aim of this study is to evaluate the reliability and accuracy of the new multifrequency BodyComp ® bioimpedance analyzer as a home based tool versus traditional Bia Vector ® . Copyright © 2006 S. Karger AG, Basel Cardiovascular disease is a leading cause of death in patients with end- stage renal disease [2], and hypertension and volume expansion [3, 4], highly prevalent in long-term peritoneal dialysis (PD) patients, may be considered the principal determinants. Wang et al. [5] demonstrated that fluid overload is the major determinant of uncontrolled hypertension (fig. 1); also malnutrition may be considered an important mortality risk factors in a PD population [1]. Bioelectrical impedance analysis (BIA) is a widely used and proven method for evaluating patient’s body composition [6–15]. Downloaded by: C.
