Serum sodium concentration
Blood glucose level
Background: A lot of risk factors for mortality have been proposed in hemodialysis patients. However, most of the findings were derived from the analyses using all of the hemodialysis patients. What we really want to know is the prognostic factor in stable hemodialysis patients who have good activities of daily living, because it is difficult to estimate their prognosis by physical appearance.
Methods: This is a 7-year observational study. The study involved registering 631 patients who had undergone hemodialysis for more than 1 year at enrollment and were still alive more than 1 year after it. Demographic and clinical data were collected to analyze the relationship with mortality. Moreover, the patients were age-stratified to investigate age-dependent prognostic factors.
Results: Low serum sodium concentration is an independent risk factor for all-cause and cardiovascular mortality common to a wide range of ages in stable hemodialysis patients. Causes of hyponatremia included the predialysis blood glucose level as well as the variables related to nutrition, inflammation, and fluid overload.
Conclusions: Low serum sodium concentration is a significant prognostic factor in stable hemodialysis patients. Low serum sodium concentration can be a clue to finding current poor glucose control in stable hemodialysis patients. Predialysis blood glucose level is one of the representative factors correlated with serum sodium concentration.
