| Abstract: | Protein-energy wasting (PEW), a syndrome involving adverse changes in nutrition and body composition, is a serious problem associated with morbidity and mortality in patients with end-stage renal disease (ESRD). The pathogenesis of PEW is multifactorial, and the underlying mechanisms are not fully understood. However, recent translational work has provided compelling evidence for a causal role of parathyroid hormone (PTH) in the pathogenesis of adipose tissue browning and increased energy expenditure, a critical component of PEW in ESRD. These results provide a biological explanation for the clinical association between secondary hyperparathyroidism (SHPT) and PEW in hemodialysis patients and may serve as an additional rationale for treating SHPT. Large-scale clinical and epidemiological studies should determine the clinical significance of SHPT as a contributor to PEW and establish the optimal management of SHPT to ameliorate PEW. |
