Abstract
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.

Werthman EH, Colloca L, Oswald LM. Adverse childhood experiences and burn pain: a review of biopsychosocial mechanisms that may influence healing. Pain Rep 2022; 7:e1013. [PMID: 38304399 PMCID: PMC10833651 DOI: 10.1097/pr9.0000000000001013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 04/09/2022] [Accepted: 04/20/2022] [Indexed: 11/26/2022] Open
Abstract
Adverse childhood experiences (ACEs) affect over half of the adults in the United States and are known to contribute to the development of a wide variety of negative health and behavioral outcomes. The consequences of ACE exposure have been studied in patient populations that include individuals with gynecologic, orthopedic, metabolic, autoimmune, cardiovascular, and gastrointestinal conditions among others. Findings indicate that ACEs not only increase risks for chronic pain but also influence emotional responses to pain in many of these individuals. A growing body of research suggests that these effects may be the result of long-lasting changes induced by ACEs in neurobiological systems during early development. However, one area that is still largely unexplored concerns the effects of ACEs on burn patients, who account for almost 450,000 hospitalizations in the United States annually. Patients with severe burns frequently suffer from persistent pain that affects their well-being long after the acute injury, but considerable variability has been observed in the experience of pain across individuals. A literature search was conducted in CINAHL and PubMed to evaluate the possibility that previously documented ACE-induced changes in biological, psychological, and social processes might contribute to these differences. Findings suggest that better understanding of the role that ACEs play in burn outcomes could lead to improved treatment strategies, but further empirical research is needed to identify the predictors and mechanisms that dictate individual differences in pain outcomes in patients with ACE exposure and to clarify the role that ACE-related alterations play in early healing and recovery from burn injuries.
