Abstract

Objective: The incidence of chronic kidney disease (CKD) is on the rise. CKD patients are at high risk of cardiovascular (CVD) and all-cause mortality. CKD patients have several endocrine disorders, including low levels of dehydroepiandrosterone sulfate (DHEA-S). In the general population, low levels of DHEA-S are associated with high CVD and all-cause mortality. The aim of this study was to analyze the prognostic value of plasma DHEA-S on the survival of CKD patients on hemodialysis. Method: This was a single-center prospective cohort study on two hundred CKD patients on hemodialysis, which assessed the prognostic value of plasma DHEA-S on their survival. Result: We found that plasma DHEA-S levels were negatively associated with age, and positively associated with dialysis duration and plasma creatinine, albumin, and phosphate levels in hemodialysis men. Elderly patients with co-morbidities (i.e. diabetes mellitus, congestive heart failure, and chronic obstructive pulmonary disease), poorer fluid control which was evaluated by higher cardiothoracic ratio, and low plasma creatinine and albumin levels seemed to have poor prognosis in hemodialysis men. Furthermore, low plasma DHEA-S levels were significantly associated with CVD-related [hazard ratio (HR) = 3.877; P=0.021], non-CVD-related (HR = 3.522; P=0.016), and all-cause mortality (HR = 3.667; P=0.001) in hemodialysis men. But low plasma DHEA-S levels were not significantly associated with CVD-related, non-CVD-related, and all-cause mortality in hemodialysis women. Multivariate Cox regression analysis suggested that low plasma DHEA-S levels are significantly and independently associated with all-cause mortality in hemodialysis men (HR = 2.933; P=0.033). Conclusion: The study suggested that low plasma DHEA-S was independently and significantly associated with all-cause mortality in CKD hemodialysis men.
