Research progress of sarcopenic obesity and chronic liver disease / 中华肝脏病杂志

Sarcopenia has attracted increasing attention with the study of nutrition in patients with liver disease. Sarcopenia is an independent risk factor for a poor prognosis of liver disease and is becoming increasingly common in patients with liver disease. Studies have shown that patients with liver disease and sarcopenic obesity have a worse prognosis than patients with liver disease and simple sarcopenia or obesity. In clinical practice, it is easy to recognize patients with malnutrition and decreased muscle mass, but we often ignore those patients with normal body weight or even obesity who will likewise experience muscle mass loss. Simply relying on the monitoring of body mass and body mass index to assess the nutritional and muscle status of patients with liver disease is not accurate. At present, our understanding of the relationship between chronic liver disease and sarcopenic obesity is still poorly understood. In this paper, the research progress on chronic liver disease, sarcopenia, and sarcopenic obesity in recent years is reviewed so as to provide a theoretical basis for improving the clinical prognosis of patients with liver disease.

Research progress on pathogenesis and potential therapeutic target of sarcopenia obesity / 中国临床药理学与治疗学

Sarcopenia obesity (SO), a specific disease with co-occurrence of obesity and sarcopenia, is shown clinically as abnormal accumulation of fat, decreased mass and strength of muscle, and increased risk of incidence and mortality of other chronic diseases. Currently, there exist various definitions and diagnoses about SO in the various regions of the world. Its prevalence in populations elevates in an age-dependent manner. This article summarized the possible pathogenesis of SO from the view of chronic inflammation, oxidative stress, insulin resistance, and Hippo pathway, subsequently listed and analyzed potential pharmacological targets (fibroblast growth factor, CD44, adiponectin, etc) involved in treating SO, in order to provide new ideas for clinical diagnosis, treatment of SO patients and research and development of innovative drugs.
