Chronic obstructive pulmonary disease (COPD) has become one of the most fatal diseases of the century considering mortality and morbidity levels worldwide. This disease is an inflammatory response to environmental stress and tobacco smoking. Although spirometry is the gold-standard diagnostic test administrated in primary and secondary care, it often exhibits low accuracy in cases of predicting disease worsening and possible bias due to the operator, patient, and conditions. Recent developments in proteomics research suggest that the presence of protein biomarkers can aid in the accurate diagnosis and prediction of disease outcomes. This review presents the cutting-edge research progress in the area of protein biomarkers towards the management of COPD. The literature review was confined to protein biomarkers in saliva and sputum because testing these bodily fluids shows great promise for point-of-care (POC) testing due to its practicality, non-invasiveness and inexpensive handling and sampling. Although it is conclusive that more studies on sputum and saliva are needed, this review studies the promising clinical value of interleukin (IL)-6 and IL-8, matrix metalloproteinase (MMP)-8 and MMP-9, C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and neutrophil elastase (NE). Following the critical analysis of salivary and sputum biomarkers, the recent development of POC biosensors for the multiplexed detection of biomarkers is also reported. Overall, the review aims to explore the possibility for the future development of POC sensors for chronic lung disease management utilizing clinically relevant biomarkers in saliva and sputum.

痰液和唾液蛋白生物标记物以及护理点生物传感器,用于COPD的管理。

考虑到全球的死亡率和发病率水平,慢性阻塞性肺疾病(COPD)已成为本世纪最致命的疾病之一。这种疾病是对环境压力和吸烟的炎症反应。尽管肺活量测定法是基层和二级医疗机构执行的金标准诊断测试,但在预测疾病恶化以及由于操作人员,患者和状况而可能造成的偏见的情况下,肺活量测定法通常显示出较低的准确性。蛋白质组学研究的最新进展表明,蛋白质生物标志物的存在可以帮助准确诊断和预测疾病结局。这篇综述介绍了蛋白质生物标志物在COPD管理方面的前沿研究进展。文献综述仅限于唾液和痰中的蛋白质生物标记物,因为对这些体液进行测试显示出了即时诊(POC)检测的巨大希望,因为它具有实用性,无创性以及廉价的处理和采样方法。尽管有结论需要对痰液和唾液进行更多的研究,但本综述研究了白介素(IL)-6和IL-8,基质金属蛋白酶(MMP)-8和MMP-9,C反应蛋白的临床价值( CRP),肿瘤坏死因子-α(TNF-α)和中性粒细胞弹性蛋白酶(NE)。在对唾液和痰液生物标志物进行严格分析之后,还报道了用于生物标志物多重检测的POC生物传感器的最新发展。全面的,
