Relationship between plasma 25-hydroxyvitamin D and cathelicidin (LL-37) in critically ill subjects with sepsis, critically ill subjects without sepsis and healthy subjects. The was a positive relationship between plasma 25-hydroxyvitamin D (25(OH)D) and systemic LL-37 levels in all three subject groups (critically ill subjects with sepsis, critically ill without sepsis and healthy controls). This remained significant after adjustment for differences in race and patient population (R² = 0.21, P = 0.05).
