OBJECTIVE: Water balance and blood pressure (BP) alterations are strongly associated in haemodialysis (HD) patients. Aim of this study was to determine whether bioelectrical impedance analysis (BIA) parameters can be used as predictors of intradialytic hypotension (IDH). DESIGN AND METHOD: We conducted an observational study of chronic HD patients. BIA was measured before the HD procedure using InBody S10 (Biospace, Seoul, Korea) body composition analyzer. Intracellular water (ICW), extracellular water (ECW), total body water (TBW), ECW/TBW ratio and phase angle (PhA) were selected as markers of hydration state and thus possible predictors of IDH...

INTRODUCTION: Phase Angle (PhA) is a ratio of whole body reactance and resistance obtained from Bioelectrical Impedance Analysis (BIA). It indicates cellular health and integrity and is considered as prognostic tool in medical disorders. In spite of prognostic potentials of PhA, it has limited usefulness in clinical practice and in population studies because of non-availability of normal population reference limits for comparison. Moreover, it is influenced by various factors like age, sex, race and body composition (i...

BACKGROUND: Bariatric surgery is proven to be the most effective therapy for obesity. However, the targeted weight reduction is not always achieved. Reliable predictors for postoperative success are rare. Also, most available predictors, such as gender and socioeconomic status, cannot be influenced. The aim of the study was to assess the reliability of the phase angle (PhA) as a predictor of weight reduction and body composition after bariatric surgery. METHODS: One hundred seventy-three patients (127 with Roux-en-Y gastric bypass and 46 with sleeve gastrectomy), treated between January 2004 and December 2012, were included into this prospective trial...

Muscle strength can define the general muscular fitness (MF) measurable through hand-grip strength (HG), which is a factor that relates to the health of people of different ages. In this study we evaluated the muscle strength together with a bioimpedance electric analysis in 223 healthy Colombian adult subjects. The bioelectrical impedance vector analysis (BIVA) was conducted to determine the resistance (R), reactance (Xc) and phase angle (PhA). We classified the subjects into three groups (for tertiles), obtaining lower values of R and Xc in subjects with lower HG, plus a high correlation between PhA and HG...

BACKGROUND: In critically ill patients, muscle loss is associated with adverse outcomes. Raw bioelectrical impedance analysis (BIA) parameters (eg, phase angle [PA] and impedance ratio [IR]) have received attention as potential markers of muscularity, nutrition status, and clinical outcomes. Our objective was to test whether PA and IR could be used to assess low muscularity and predict clinical outcomes. METHODS: Patients (≥18 years) having an abdominal computed tomography (CT) scan and admitted to intensive care underwent multifrequency BIA within 72 hours of scan...

BACKGROUND: Obesity, metabolic syndrome (MetS), and psoriasis, largely driven by environmental factors, show multiple bidirectional associations, with important metabolic implications in psoriatic patients. Besides body mass index (BMI) as a measure of obesity, data on phase angle (PhA), a direct measure by bioelectrical impedance analysis (BIA), used as a marker of cellular health and a predictor of morbidity and mortality in various diseases, are still lacking in psoriasis. In this case-control, cross-sectional study, we investigated the PhA in 180 pairs of adult psoriatic patients and healthy controls, evaluating also the potential use of the PhA as marker of the clinical severity, the quality of life, and the presence of the MetS in psoriatic patients...

OBJECTIVE: The phase angle identifies changes in tissue's electrical properties assessed by bioelectrical impedance measurement and it can predict prognosis in some conditions. Percutaneous endoscopic gastrostomy (PEG) is commonly used in patients with severe nutritional problems, but there is a need to improve the clinical decision-making for using PEG. We examined if a decreased phase angle predicts complications, short-term mortality (within 60 days of PEG insertion), or inflammatory markers (high C-reactive protein [CRP] levels or low albumin levels) following PEG insertion...
