Objective of this prospective study was to investigate clinical use and prognostic value of BIA-derived phase angle and alterations in body composition for hepatitis C infection HCV following antiviral therapy. Methods 37 consecutive patients with HCV infection were enrolled BIA was performed and PA was calculated from each pair of measurements. 22 HCV genotype 3 patients treated for 24 weeks and 15 genotype 1 patients treated for 48 weeks were examined before and after antiviral treatment and compared to 10 untreated HCV patients at 0 24 and 48 weeks. Basic laboratory data were correlated to body composition alterations. Results Significant reduction in body fat BF kg vs. kg genotype1 kg vs. kg genotype 3 and body cell mass BCM kg vs. kg genotype1 kg vs. kg genotype 3 was found following treatment. PA in genotype 3 patients was significantly lowered after antiviral treatment compared to initial measurements vs. . Total body water TBW was significantly decreased in treated patients with genotype 1 l vs. l . PA reduction was accompanied by flu-like syndromes whereas TBW decline was more frequently associated with fatigue and cephalgia. Discussion BIA offers a sophisticated analysis of body composition including BF BCM and TBW for HCV patients following antiviral regimens. PA reduction was associated with .
