老年人呼吸道易受细菌感染。老年人由于免疫功能减退和炎性反应降低,呼吸道感染的临床表现可以发生改变。本文通过测定血清C-反应蛋白(CRP)、血浆弹性硬蛋白酶复合体(EC)和乳铁蛋白(LF)来探讨老年人下呼吸道感染的炎性应答。 疑诊急性下呼吸道感染41例,分为肺炎和非肺炎性肺部感染(Chest Infection,CI)组。其中肺炎组25例,男16、女9例,平均年龄81岁(SD 5.8),有新近出现的咳嗽、多痰、呼吸困难症状及胸片上显示阴影;CI组16例,男9、女7例,平均年龄82岁(SD 6.6),仅有新近发生的呼吸道症状而无胸片阴影。 患者做了全血计数和分类,以及细菌培养。在住院
The elderly respiratory tract susceptible to bacterial infection. The elderly may experience a change in the clinical manifestations of respiratory infections due to decreased immune function and decreased inflammatory response. This article explored the inflammatory response of lower respiratory tract infection in the elderly by measuring serum C-reactive protein (CRP), plasma elastase (EC) and lactoferrin (LF). Suspected acute lower respiratory tract infection in 41 cases, divided into pneumonia and non-pneumonia (Chest Infection, CI) group. There were 25 cases in the pneumonia group, 16 males and 9 females, with an average age of 81 years (SD 5.8). There were newly-emerged symptoms of cough, phlegm, dyspnea and shadow on the chest radiograph. CI group, 16 males and 9 females For example, the mean age was 82 years (SD 6.6) with only recent respiratory symptoms without a chest radiograph. Patients performed whole blood count and classification as well as bacterial culture. In hospital
