Abstract

Background: This study aimed to evaluate the association between phase angle, muscle strength, and muscle mass in patients undergoing kidney transplantation.

Methods: Patients whose pre- and follow-up phase angles were measured after kidney transplantation were enrolled. Phase angle and body composition were measured using a multi-frequency bioimpedance analysis device before and at 7 and 14 days and 3, 6, and 12 months after transplantation. Muscle strength was evaluated using handgrip strength (HGS). Low HGS was defined as < 28 kg in males and < 18 kg in females. Low muscle mass was defined as an appendicular lean mass index of < 7.0 kg/m2 in males and < 5.7 kg/m2 in females.

Results: Eighty-eight patients (mean age 52.3 ± 10.1 years) were analyzed. The mean phase angle of pre-transplantation was 5.0 ± 1.0°. Body fat percentage was significantly higher at 6 and 12 months after transplantation than pre-transplantation (P < 0.0001). Twelve months after kidney transplantation, the prevalence of low HGS decreased (pre-transplantation vs. 12 months post-transplantation: 28.4% vs. 17.0%), and the prevalence of low muscle mass (pre-transplantation vs. 12 months post-transplantation: 21.6% vs. 28.4%) increased. The pre-transplantation phase angle was significantly associated with low muscle mass at 12 months after kidney transplantation (odds ratio [OR]: 0.34; 95% confidence interval [CI]: 0.16-0.72; P = 0.005). The pre-transplantation phase angle was not significantly associated with low HGS (OR: 0.37; 95% CI 0.12-1.17; P = 0.090) 12 months after kidney transplantation.

Conclusions: Pre-transplantation phase angle can predict muscle mass status 12 months after kidney transplantation.

移植前的相位角可预测肾移植后的低肌肉质量状况。
背景:本研究旨在评估肾移植患者的相位角、肌肉力量和肌肉质量之间的关系:本研究旨在评估肾移植患者的相位角、肌肉力量和肌肉质量之间的关系:方法:研究对象为肾移植术前和术后测量相位角的患者。在移植前、移植后 7 天和 14 天以及移植后 3、6 和 12 个月时,使用多频生物阻抗分析装置测量相位角和身体成分。肌肉力量采用手握力量(HGS)进行评估。男性和女性的低 HGS 定义为 2:对 88 名患者(平均年龄为 52.3 ± 10.1 岁)进行了分析。移植前的平均相位角为 5.0 ± 1.0°。移植后 6 个月和 12 个月的体脂率明显高于移植前(P 结论:移植前的相位角对移植后的体脂率有影响:移植前相位角可预测肾移植 12 个月后的肌肉质量状况。

期刊介绍: Clinical and Experimental Nephrology is a peer-reviewed monthly journal, officially published by the Japanese Society of Nephrology (JSN) to provide an international forum for the discussion of research and issues relating to the study of nephrology. Out of respect for the founders of the JSN, the title of this journal uses the term “nephrology,” a word created and brought into use with the establishment of the JSN (Japanese Journal of Nephrology, Vol. 2, No. 1, 1960). The journal publishes articles on all aspects of nephrology, including basic, experimental, and clinical research, so as to share the latest research findings and ideas not only with members of the JSN, but with all researchers who wish to contribute to a better understanding of recent advances in nephrology. The journal is unique in that it introduces to an international readership original reports from Japan and also the clinical standards discussed and agreed by JSN.
