Low vitamin D concentrations are prevalent in chronic kidney disease (CKD) patients. We investigated the relationship between plasma 25-hydroxyvitamin D (25(OH)D) or 1,25-dihydroxyvitamin D (1,25(OH)2D) concentrations with death, cardiovascular events (CVE) and dialysis initiation in patients with advanced CKD. Study Design: The Homocysteine Study was a randomized double-blind trial evaluating the effects of high doses of folic acid on death and chronic dialysis initiation in patients with advanced CKD (stage 4 and 5 not yet on dialysis). 25(OH)D and 1,25(OH)2D concentrations were measured in stored plasma samples obtained 3 months after trial initiation and evaluated at clinically defined cutoffs (<10, 10-30, and >30 ng/mL) and tertiles (< 15, 15-22, and >22 pg/mL), respectively. Cox-proportional hazard models were used to examine the association between vitamin D concentrations and clinical outcomes. 1,099 patients with advanced CKD from 36 Veteran Affairs Medical Centers 25(OH)D and 1,25(OH)2D concentrations Death, CVE and time to initiation of chronic dialysis. After a median follow-up period of 2.9 years, 41% (n=453) died, while 56% (n=615) initiated dialysis. Mean 25(OH)D and 1,25(OH)2D concentrations were 21±10 ng/mL and 20±11 pg/mL, respectively. After adjustment for potential confounders, the lowest tertile of 1,25(OH)2D was associated with death (HR, 1.33; 95% CI, 1.01-1.74) and initiation of chronic dialysis (HR, 1.78; 95% CI, 1.40-2.26), compared to the highest tertile. The association with death and initiation of dialysis was moderately attenuated after adjustment for plasma fibroblast growth factor-23 (FGF23) concentrations (HRs of lower tertiles of 1.20 [95% CI, 0.91-1.58] and 1.56 [95% CI, 1.23-1.99], respectively, compared to highest tertile). There was no association between 25(OH)D concentrations and outcomes. Participants were mostly male. Low plasma 1,25(OH)2D concentrations are associated with death and initiation of chronic dialysis in advanced CKD. Fibroblast growth factor-23 may attentuate this relationship.
