摘要
肺部感染是老年患者的常见病，感染的病原体多样，其临床症状和体征常缺乏特异性，实验室指标不典型，易误诊及延误治疗。降钙素原（procaleitonin，PCT）作为细菌感染的一种新型炎症参数，有较高的特异性及敏感性。目前认为PCT在诊断和感染性疾病的治疗中有一定指导意义，但PCT与老年患者肺部感染的相关性报道较少。以下就PCT的研究现状及其在老年肺部感染患者诊治中的应用进展作一综述。
Pulmonary infection is a common disease in the elderly. The pathogen is varied,and its clinical symptoms and signs often lack of specificity. Laboratory indicators are not typical, which lead easily to misdiagnose and delayed treatment. As a new type of inflammation parameters,the infection of procalcitonin has higher specificity and sensitivity. It is believed that procalcitonin had some value in the diagnosis and treatment of infectious diseases, but the correlation between the elderly with pulmonary infection was less. Here is a survey of the status of PCT and its application in the diagnosis and treatment of pulmonary infections in elderly patients.
