AIM: The goal was to analyze the link between blood levels of calcidiol and all-cause, cardiac and infectious diseases, and mortality due to cancer in hemodialysis patients. PATIENTS AND METHODS: This study retrospectively evaluated a representative sub-cohort (n=6,518) of German hemodialysis patients from the incidence cohorts 1997-2006. RESULTS: Most (58.8%) were found to be vitamin D deficient (25(OH)D<20 ng/ml), with 41.2% being severely deficient (25(OH)D<12.5 ng/ml). All-cause mortality risk more than doubled in patients with severe deficiency (adjusted odds ratio (aOR)=2.67; 95% confidence interval (CI)=2.30-3.10; p<0.0001). Comparable data were obtained for mortality from cardiac disease (aOR=1.57; 95% CI=1.30-1.88; p<0.0001), infectious disease (aOR=1.48; 95% CI=1.15-1.90; p=0.0026), and cancer (aOR=1.51; 95% CI=1.09-2.08; p=0.0121), respectively. CONCLUSION: These data highlight the need to ensure primarily adequate 25(OH)D levels in dialysis patients for an advantage of survival.
