A new home based bioimpedance system for PD

Fluid overload and uncontrolled hypertension may be considered important mortality risk factors in peritoncal dialysis (PD) population. 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 bioimpedance 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 (R) bioimpedance analyzer as a home based tool versus traditional Bia Vector (R).
