Abstract

Introduction

Fibrotic interstitial lung diseases (ILD) are a heterogeneous group of conditions. Progression criteria include clinical, imaging, and/or lung functional decline. Currently, the 6-min walk test (6MWT) is considered the gold standard for assessing exercise-induced desaturation. The 1-min sit-to-stand test (1STST) has the advantage of being easy to perform, making it feasible for use during clinical consultations. The aim of this study was to compare the 1STST with the 6MWT in patients with fibrotic ILD to detect exercise-induced desaturation.

Methods

A multicenter cross-sectional involved patients with fibrotic ILDs from two centers. The 6MWT and 1STST were performed with a 30-min rest period between the tests. The modified Borg scale was used to assess dyspnea and lower limb fatigue and continuous SpO2 and heart rate were monitored. Desaturation was defined as SpO2 < 90 % or decline >3 %.

Results

Ninety patients were included. The median walking distance in the 6MWT was 432 m and the median number of repetitions in the 1STST was 22, with a significant correlation (p < 0.001, ρ = 0.383). In addition, the minimum SpO2 and the desaturation levels recorded during the tests exhibited a moderate significant correlation (p < 0.001, ρ = 0.502 and p < 0.001, ρ = 0.537, respectively). There was a strong association between the increase in Borg score for dyspnea and a moderate association between the increase in Borg score for lower limb fatigue after both tests (p < 0.001, ρ = 0.706 and p < 0.001, ρ = 0.656, respectively).

Conclusions

This study demonstrates a significant correlation between the 6MWT and the 1STST in detecting exercise-induced desaturation.
评估纤维化间质性肺病的 1 分钟坐立试验。
导言:纤维化间质性肺病(ILD)是一类异质性疾病。进展标准包括临床、影像和/或肺功能衰退。目前,6 分钟步行测试(6MWT)被认为是评估运动引起的饱和度降低的黄金标准。1 分钟坐立测试 (1STST) 的优点是操作简便,可在临床会诊时使用。本研究的目的是比较 1STST 和 6MWT 在纤维化 ILD 患者中的应用,以检测运动诱发的失饱和度:这项多中心横断面研究涉及两个中心的纤维化 ILD 患者。进行 6MWT 和 1STST 测试时,两次测试之间有 30 分钟的休息时间。采用改良博格量表评估呼吸困难和下肢疲劳,并连续监测SpO2和心率。SpO2<90%或下降>3%即为饱和度降低:结果:共纳入 90 名患者。结果:纳入的 90 名患者中,6MWT 步行距离的中位数为 432 米,1STST 重复次数的中位数为 22 次,两者之间存在显著相关性(p 结论:该研究表明,6MWT 和 1STST 之间存在显著相关性:这项研究表明,6MWT 和 1STST 在检测运动诱发的饱和度降低方面存在明显的相关性。

期刊介绍: Respiratory Medicine is an internationally-renowned journal devoted to the rapid publication of clinically-relevant respiratory medicine research. It combines cutting-edge original research with state-of-the-art reviews dealing with all aspects of respiratory diseases and therapeutic interventions. Topics include adult and paediatric medicine, epidemiology, immunology and cell biology, physiology, occupational disorders, and the role of allergens and pollutants. Respiratory Medicine is increasingly the journal of choice for publication of phased trial work, commenting on effectiveness, dosage and methods of action.
