Major thermal burn injuries result in approximately 40,000 hospitalizations in the United States each year. Chronic pain affects up to 60% of burn survivors, and Black Americans have worse chronic pain outcomes than White Americans. Mechanisms of chronic pain pathogenesis after burn injury, and accounting for these racial differences, remain poorly understood. Due to socioeconomic disadvantage and differences in skin absorption, Black Americans have an increased prevalence of Vitamin D deficiency. We hypothesized that peritraumatic Vitamin D levels predict chronic pain outcomes after burn injury and contribute to racial differences in pain outcomes. Among burn survivors (n = 77, 52% White, 48% Black, 77% male), peritraumatic Vitamin D levels were more likely to be deficient in Blacks vs Whites (27/37 [73%] vs 14/40 [35%], P < .001). Peritraumatic Vitamin D levels were inversely associated with chronic post-burn pain outcomes across all burn injury survivors, including those who were and were not Vitamin D deficient, and accounted for approximately one-third of racial differences in post-burn pain outcome. Future studies are needed to evaluate potential mechanisms mediating the effect of Vitamin D on post-burn pain outcomes and the potential efficacy of Vitamin D in improving pain outcomes and reducing racial differences.
