Abstract

An accelerated muscle wasting was the pivotal factor for protein-energy wasting in end stage renal disease. However, very few researches have examined the skeletal muscle quantity and quality in clinical patients. This study investigated the muscle morphologic changes by magnetic resonance imaging (MRI) and analyzed the related factors in hemodialysis patients. Fifty-eight patients receiving maintenance hemodialysis (HD) were investigated and 28 healthy adults with gender and age matched were used as controls (Control). Anthropometry, cytokine factors, and laboratory data were measured. The muscle and intermuscular adipose tissues (IMAT) were analyzed via a Thigh MRI. The bicep samples were observed after HE staining. Homeostatic model assessment of insulin resistance (HOMA-IR) was measured and their association with muscle wasting was analyzed. HD patients tended to have a lower protein diet, anthropometry data, and serum albumin, but the C reactive protein and interleukin-6 increased significantly. The MRI showed that HD patients had less muscle mass and a lower muscle/total ratio, but the fat/muscle and IMAT was higher when compared to the Control group. The muscle fiber showed atrophy and fat accumulation in the biceps samp...Continue Reading

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
