DESCRIPTION Abstract: The role of vitamin D in bone metabolism is well established, but recent epidemiologic and basic science studies suggest that vitamin D related pathways are involved in the determination of pulmonary function, risk of infection, and respiratory health, all factors influencing morbidity and mortality in chronic SCI. These observations regarding vitamin D are highly significant as vitamin D deficiency and insufficiency is common in chronic spinal cord injury. Previous research conducted at VA Boston in persons with chronic SCI has demonstrated that longitudinal decline in pulmonary function and chest illness risk are not attributable to level and severity of injury, but to other potentially modifiable factors. The VA Boston SCI research program has conducted epidemiologic studies focused on identifying factors responsible for pulmonary function decline and pulmonary-related illness in chronic SCI. In a cohort of 330 persons with chronic SCI, it is proposed to longitudinally assess the relationship between vitamin D levels with pulmonary function and the risk of future chest illness. Understanding these adverse effects of lower vitamin D levels is particularly important in SCI because of the increased risk of pulmonary-related diseases and infection. Our approach is efficient because it will take advantage of a large SCI cohort enrolled in an ongoing longitudinal health study. The demonstration of an association between pulmonary function decline and an increased risk of chest illness with lower levels of vitamin D would result in a clinical trial assessing the potential benefits of vitamin D supplementation that would potentially identify an approach to disease prevention in SCI.

描述 摘要：维生素 D 在骨代谢中的作用已得到充分证实，但最近的流行病学和基础科学研究表明，维生素 D 相关途径涉及肺功能、感染风险和呼吸系统健康的确定，所有这些因素都会影响发病率和死亡率。慢性 SCI 中。这些关于维生素 D 的观察结果非常重要，因为维生素 D 缺乏和不足在慢性脊髓损伤中很常见。波士顿退伍军人管理局之前对慢性脊髓损伤患者进行的研究表明，肺功能的纵向下降和胸部疾病风险并不是由受伤的程度和严重程度造成的，而是由其他潜在的可改变因素造成的。 VA 波士顿 SCI 研究项目开展了流行病学研究，重点是确定慢性 SCI 中导致肺功能下降和肺部相关疾病的因素。在 330 名慢性 SCI 患者的队列中，建议纵向评估维生素 D 水平与肺功能和未来胸部疾病风险之间的关系。了解较低维生素 D 水平的这些不利影响对于以下方面尤为重要： SCI 因为肺部相关疾病和感染的风险增加。我们的方法是有效的，因为它将利用参与正在进行的纵向健康研究的大量 SCI 队列。如果维生素 D 水平较低，肺功能下降与胸部疾病风险增加之间存在关联，那么将开展一项临床试验来评估补充维生素 D 的潜在益处，这可能会确定预防 SCI 疾病的方法。
