We prospectively evaluated the effect of fluid retention on bioelectrical impedance analysis (BIA) as a simple method for the estimation of body cell mass (BCM<jats:sub>BIA<\/jats:sub>) in 41 patients with cirrhosis (n = 20 with ascites; n = 21 without ascites) using total body potassium counting (BCM<jats:sub>TBP<\/jats:sub>) as a reference method. Arm muscle area and creatinine\u2013derived lean body mass were compared with total body potassium data. In patients total body potassium was 24.4% lower than in controls and this loss was more severe in patients with ascites (-34.1%; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; .01). BCM<jats:sub>BIA<\/jats:sub> and BCM<jats:sub>TBP<\/jats:sub> were closely correlated in controls (<jats:italic toggle=\"yes\">r<\/jats:italic>\n                                 <jats:sup>2<\/jats:sup> = .87, <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; .0001), patients without ascites (<jats:italic toggle=\"yes\">r<\/jats:italic>\n                                 <jats:sup>2<\/jats:sup> = .94, <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; .0001) and patients with ascites (<jats:italic toggle=\"yes\">r<\/jats:italic>\n                                 <jats:sup>2<\/jats:sup> = .56, <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; .0001). Removal of 6.2 \u00b1 3 L of ascites had only minor effects on BCM<jats:sub>BIA<\/jats:sub> (deviation of -0.18 kg\/L ascites). Limits of agreement between both methods were wider in patients with ascites than in patients without (6.2 vs. 4.2 kg). In patients without ascites arm muscle area (r<jats:sup>2<\/jats:sup> = .64; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; .001) and lean body mass (r<jats:sup>2<\/jats:sup> = .55; <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; .001) correlated significantly with total body potassium, but not in patients with ascites. For assessment of protein malnutrition in patients with cirrhosis, body cell mass determination by use of BIA offers a considerable advantage over other widely available but less accurate methods like anthropometry or the creatinine approach. Despite some limitations in patients with ascites, BIA is a reliable bedside tool for the determination of body cell mass in cirrhotic patients with and without ascites.<\/jats:p>\n
