The 1,25(OH)D:25(OH)D ratio showed a highly significant inverse correlation with serum hepcidin concentrations in patients with IBD (Kendall τ 0.19, P = 0.005; Figure 4 a).
The 1,25(OH)D:25(OH)D ratio showed a highly significant inverse correlation with serum hepcidin concentrations in patients with IBD (Kendall τ 0.19, P = 0.005; Figure 4 a).
Furthermore, we identified a clear trend toward an inverse association of serum 25(OH)D levels with iron deficiency anemia (β [SE] = −0.385 [0.199], P = 0.054) and anemia in general (β [SE] = −0.364 [0.200], P = 0.069) in patients with IBD.
Taking into account the entire IBD population, the result was almost significant (β [SE] = 0.258 [0.131], P = 0.055).
Despite a statistical trend, hemoglobin levels and diagnosis of anemia were not significantly influenced by vitamin D status in our cohort of adult patients with IBD.
Serum iron (β [SE] = 0.180 [0.096], P = 0.065) showed a trend toward a positive multivariate association with vitamin D sufficiency.
