Abstract

PURPOSE
The burn increase the requirement for the antioxidative vitamin C and decrease the plasma concentration of vitamin D due to the loss of skin body surface area. We investigated the vitamin C and D status and the prevalence of vitamin C and D insufficiency in adult burn patients undergoing rehabilitative therapy.
METHODS
256 burn patients admitted to the department of rehabilitation medicine from April 2013 to September 2014 were tested for the plasma level of vitamin C and D[25(OH)D]. Vitamin C insufficiency was considered as <26.1micromol/L and vitamin D insufficiency as <20 ng/ml. We compared the mean plasma level of vitamin C and D[25(OH)D] according to burned percent of total body surface area (TBSA).
RESULTS
Vitamin C insufficiency in 63.3% and vitamin D deficiency in 87.1%. In burn patients of TBSA> or =20%, mean plasma concentration of vitamin C and vitamin D[25(OH)D] were significantly lower (P=0.023, P<0.001). With adjusting for potential confounder such as age, sex, burn type, mean serum 25 (OH)D levels was significantly decreased 0.07 ng/ml per one percent of burned surface area (beta=-0.07, P<0.001), but with adjusting for age, sex, burn type, length of ICU stay and duration from burn injury to sampling, vitamin C and vitamin D[25(OH)D] were not significantly decreased (P=0.221, P=0.142).
CONCLUSION
Vitamin C and D insufficiency were common nutrient problems in burn patients undergoing rehabilitative therapy. Further studies will be needed to establish the effective way to improve vitamin C and D status and prevent nutritional complications.
