肌少症指数在肌少症中的应用进展

Progress in the Application of Sarcopenia Index in Sarcopenia

摘要: 肌肉减少症是一种渐进性的全身骨骼肌质量、力量和功能的下降。这种情况在慢性消耗性疾病及重症患者中很常见，并且可以增加不良预后的风险，随着年龄的增长，尤其影响老年患者。因此早期诊断肌少症进行早期干预可以极大程度地减轻再住院与死亡风险，目前一些新技术，包括双能X线吸收仪、计算机断层扫描、超声和生物阻抗分析等多种成像方式已经被证实用于诊断和预后肌肉减少症，然而由于其繁杂的诊断流程及操作步骤，对于患消耗性疾病的老年患者及危重症患者来说，这些技术有诸多不便。肌肉减少症指数是诊断肌少症、预测慢性消耗性疾病及危重症患者的预后和营养不良的重要工具。

Abstract: Sarcopenia is a progressive loss of mass, strength, and function of skeletal muscle throughout the body. This condition is common in patients with chronic wasting disease and severe illness and can increase the risk of poor prognosis, especially affecting older patients as they age. Therefore, early diagnosis and early intervention of sarcopenia can greatly reduce the risk of re-hospitalization and death. Currently, some new technologies, including dual-energy X-ray absorptometry, computed tomography, ultrasound, bioimpedance analysis and other imaging methods, have been proved to be used in the diagnosis and prognosis of sarcopenia. However, due to its complicated diagnostic procedures and operational procedures, for elderly patients with wasting diseases and critically ill patients, these technologies are inconvenient. The sarcopenia index is an important tool for diagnosing sarcopenia and predicting prognosis and malnutrition in patients with chronic wasting disease and critical illness.
