The role of fat-soluble vitamins for graft-versus host disease after myeloablative conditioning in allogeneic stem cell transplanted patients

| Summary: | Abstract Whether the fat-soluble vitamins A, D, E, and K are associated with development of graft-versus-host disease (GvHD) after allogeneic stem cell transplantation, is unclear. We assessed if the levels of these vitamins were associated with development of GvHD during the first year after transplantation using data from a two-armed randomized nutritional intervention trial. Changes in plasma levels during 1-year follow-up were analyzed using a linear mixed model for repeated measurements. Vitamin A, D, E, and K levels changed significantly the first year in both study arms (p < 0.001). Higher levels of vitamin E over time were associated with less acute GvHD grades 3–4 (OR = 0.997, 95% CI: (0.994, 0.999), p = 0.017). No associations were found with vitamin A, D, E and K levels and chronic GvHD. Multivariable analysis adjusted for treatment group, age, pre-transplant vitamin level and risk factors for GvHD did not change the results. Six weeks post-transplantation, higher levels of vitamin E were associated with less acute GvHD grades 3–4, (p = 0.012). In conclusion, we found an association between higher levels of vitamin E over time and less severe acute GvHD. Whether this reflects a causal relationship warrants further study.
