摘 ? 要:目的 ?探討血清超敏C反應蛋白、前清蛋白及降鈣素原聯合檢測在重癥肺炎患者中的變化及診斷的臨床意義。方法 ?選取2017年6月~2018年5月我院呼吸內科收治的肺炎患者70例作為研究對象,依據病情分為重癥肺炎組與非重癥肺炎組,同時選取30例健康體檢者作為對照組,對比各組血清hc-CRP、PA及PCT結果并進行分析。結果 ?重癥肺炎組血清hc-CRP及PCT水平分別為(15.44±1.76)mg/L、(0.92±0.22)ng/ml,高于非重癥肺炎組(9.24±1.14)mg/L、(0.67±0.15)g/ml和對照組(2.66±0.26)mg/L、(0.16±0.02)g/ml(P<0.05),血清PA(87.62±6.74)mg/L低于非重癥肺炎組(165.49±21.26)mg/L和對照組(297.54±34.63)mg/L(P<0.05),非重癥肺炎組與對照組相比,血清hc-CRP、PA及PCT差異具有統計學意義(P<0.05);PCT敏感度最高,PA特異性最高,三項聯合檢測陽性率高于單項檢測。結論 ?hc-CRP、PA及PCT對于重癥肺炎診斷均有一定的臨床診斷及鑒別診斷意義,并且三項聯合檢測可提高敏感度和特異性。

Abstract:Objective ?To investigate the clinical significance of serum hypersensitive C-reactive protein, prealbumin and procalcitonin in the diagnosis of severe pneumonia.Methods ?70 ?patients with pneumonia admitted to our hospital from June 2017 to May 2018 were selected as subjects. According to the condition, they were divided into severe pneumonia group and non-severe pneumonia group. 30 healthy subjects were selected as the control group. Serum hc-CRP, PA and PCT results were analyzed and analyzed.Results ?The serum hc-CRP and PCT levels in severe pneumonia group were (15.44±1.76) mg/l, (0.92±0.22) ng/ml, higher than those in non-severe pneumonia group which were(9.24±1.14) mg/L,(0.67 ±0.15) g/ml respectively and (2.66±0.26) mg/l,(0.16±0.02) g/ml in control group (P<0.05).Serum PA (87.62±6.74) mg/L was lower than that in non-severe pneumonia group (165.49±21.26) mg/l and control group (297.54±34.63) mg/L(P<0.05).Compared with the control group, the serum hc-CRP,PA and PCT in the non-severe pneumonia group were significantly different(P<0.05).The sensitivity of PCT was the highest, the specificity of PA was the highest, and the positive rate of three combined tests was higher than that of single test.Conclusion ?Both hc-CRP,PA and PCT have some clinical and differential diagnostic significance in the diagnosis of severe pneumonia, and the combined detection can improve the sensitivity and specificity.

重癥肺炎(severe pneumonia)是指有嚴重中毒癥狀或并發癥的肺炎,其病原體感染比較復雜,臨床癥狀不典型且發展迅速而難以鑒別,臨床病死率較高。因此,快速準確對其感染早期進行診斷﹑預后判斷及治療至關重要[1]。目前對肺炎的實驗室檢查主要參考血常規白細胞總數、分類及相關炎癥指標如C反應蛋白(hc-CRP),但重癥肺炎臨床癥狀隱蔽,需要聯合多項指標進行診斷。hc-CRP是常用的炎癥反應早期指標,前清蛋白(PA)是負急性時相反應蛋白,降鈣素原(PCT)是嚴重細菌性炎癥與真菌感染的特異度指標,三項在重癥肺炎的研究較少,本研究主要探討血清hc-CRP、PA及PCT在重癥肺炎患者水平變化,為臨床診斷與治療提供參考依據。
