1,25-Dihydroxyvitamin D3 reduces early mortality post severe burn injury via alleviating endotoxemia, oxidative stress and inflammation
Severe burn patients frequently suffer from 1,25-Dihydroxyvitamin D3 (1,25-[OH]2-D3) deficiency. In this study, we investigated the effect of 1,25-[OH]2-D3 on early mortality post severe burn and potential underlying mechanisms. Our results indicate that 1,25-[OH]2-D3 significantly reduced early mortality in mice post severe burn injury. A decrease in serum lipopolysaccharide levels and an increase in serum superoxide dismutase activity were found after administration of 1,25-[OH]2-D3. Furthermore, 1,25-[OH]2-D3 demonstrated protective effects on both intestinal and lung histology and ameliorated lung inflammation. Its anti-inflammatory effect was further confirmed in airway epithelial cells. In conclusion, our study provides evidence that 1,25-[OH]2-D3 has a significant impact on the reduction of early mortality post severe burn injury, possibly through its ability to alleviate endotoxemia, oxidative stress, and inflammation. Our findings highlight the potential of 1,25-[OH]2-D3 to protect the intestinal mucosal barrier in the early stage following major burn injury and opens up new avenues for clinical application of 1,25-[OH]2-D3 in burn patients.
期刊介绍:
Burns aims to foster the exchange of information among all engaged in preventing and treating the effects of burns. The journal focuses on clinical, scientific and social aspects of these injuries and covers the prevention of the injury, the epidemiology of such injuries and all aspects of treatment including development of new techniques and technologies and verification of existing ones. Regular features include clinical and scientific papers, state of the art reviews and descriptions of burn-care in practice.
Topics covered by Burns include: the effects of smoke on man and animals, their tissues and cells; the responses to and treatment of patients and animals with chemical injuries to the skin; the biological and clinical effects of cold injuries; surgical techniques which are, or may be relevant to the treatment of burned patients during the acute or reconstructive phase following injury; well controlled laboratory studies of the effectiveness of anti-microbial agents on infection and new materials on scarring and healing; inflammatory responses to injury, effectiveness of related agents and other compounds used to modify the physiological and cellular responses to the injury; experimental studies of burns and the outcome of burn wound healing; regenerative medicine concerning the skin.
