This pilot study concerns the evaluation of the acute cytokine response to exercise and changes in this throughout a 7 week pulmonary rehabilitation programme.
17 (10 male, 7 female) stable COPD patients, mean (SD) age 69 (8) yrs, mean FEV1, 51.3 (17.3)% predicted entered into 7 weeks of rehabilitation. The acute cytokine response (ACR) was measured from serum cytokine levels; Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and C-reactive protein (CRP) taken pre, post and 1 hour post-maximal incremental shuttle walking test (ISWT). The ACR to maximal exercise was determined before rehabilitation (TO) and post rehabilitation (T7). The ACR (pre/post test) to iso-distance exercise (based on initial ISWT distance) was determined throughout the rehabilitation period at 2 (T2), 4 (T4) weeks and at the end (T7).
12 patients completed the study. Maximal ISWT distance significantly increased after rehabilitation. There was no significant change in baseline cytokine level throughout; or in pre/post-exercise cytokine levels prior to, during or following rehabilitation.
There was no significant inflammatory response associated with maximal exercise before or after training. Cytokine responses to a fixed bout of exercise did not alter markedly throughout. Clinical PR is unlikely to exacerbate systemic inflammation in COPD.
本初步研究旨在评估运动引起的急性细胞因子反应,以及在为期7周的肺康复计划中该反应的变化情况。
17名(10名男性,7名女性)稳定期慢性阻塞性肺疾病(COPD)患者,平均(标准差)年龄69(8)岁,平均第一秒用力呼气容积(FEV1)为预计值的51.3(17.3)%,参加了为期7周的康复训练。通过检测血清细胞因子水平来测量急性细胞因子反应(ACR);在最大递增往返步行试验(ISWT)前、后及后1小时采集白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)和C反应蛋白(CRP)。在康复训练前(T0)和康复训练后(T7)测定对最大运动的ACR。在整个康复期间的第2周(T2)、第4周(T4)和结束时(T7),测定对等距离运动(基于初始ISWT距离)的ACR(测试前/后)。
12名患者完成了研究。康复训练后最大ISWT距离显著增加。整个过程中基线细胞因子水平没有显著变化;康复训练前、期间或之后运动前/后细胞因子水平也没有显著变化。
训练前后与最大运动相关的炎症反应均不显著。对固定运动量运动的细胞因子反应在整个过程中没有明显改变。临床肺康复不太可能加剧COPD患者的全身炎症反应。
