Abstract:Objective To explore the clinical application value of quantitative C-reactive protein (CRP), high-sensitivity C-reactive protein (hsCRP) and blood routine test in order to provide reliable laboratory diagnostic index for clinical practice. Methods: CCRP and hsCRP were quantitatively analyzed by the CHM-4100 specific protein analyzer and the blood samples were analyzed by the Japanese MEK-8222K cell analyzer. Results: 61 of 82 patients with bacterial infectious diseases had abnormal CRP and hsCRP, the positive rate was 74.4%, the white blood cell count was more than 10.0 *10 ^ 9/L, the percentage of neutrophils was more than 80%, and the positive rate was 58.5%. Among 131 patients with non-bacterial infections, 8 had abnormal CRP and hsCRP, the positive rate was 6.1%. Leukocyte count was more than 10.0 *10^ 9/L, neutrophil percentage (Neu%) was more than 80%, 13 were positive, and the positive rate was 9.9%. 116 cases of abnormal CRP and hsCRP were found in 147 patients with cardiovascular diseases. The positive rate was 78.9%. The white blood cell count was more than 10.0 *10 ^ 9/L. The percentage of neutrophils was more than 80%. 42 cases were positive. The positive rate was 28.6%. Conclusion: The combined detection of CRP, hsCRP and blood routine is helpful to differentiate early bacterial infection from non-bacterial infection and predict cardiovascular disease

CRP、hsCRP是一種非特異性反應蛋白質,在細菌性感染和心血管疾病中,其含量可以成倍增加,是細菌感染敏感性指標,也是心血管疾病風險的預測因子之一。采用CRP、hsCRP與血常規(guī)聯(lián)合檢查,可以協(xié)助于臨床醫(yī)生診斷,正確合理用藥。
1 資料與方法
1.1 一般資料 2017年本院住院患者360例,男200例,女160例。細菌感染組82例,非細菌感染組131例,心血管疾病組147例,所有病例均為明確診斷的住院患者。
1.2 標本采集及處理 患者入院時,采集靜脈血2mL,測血常規(guī),再測CRP、hsCRP。
1.3 檢測方法 CCRP、hsCRP用CHM-4100特定蛋白儀散射乳膠免疫比濁法定量分析,血常規(guī)用日本光電MEK-8222K五分類細胞分析儀進行分析,均使用配套試劑和質控物。
2 結果
2.1 82例細菌感染性疾病患者CRP、hsCRP異常61例,陽性率74.4%,白細胞計>10.0×10^9個/L,中性粒細胞百分比(Neu%)>80%,陽性48例,陽性率58.5%。
2.2 131例非細菌感染疾病患者CRP、hsCRP異常8例,陽性率6.1%,白細胞計數(shù)>10.0×10^9個/L, 中性粒細胞百分比(Neu%)>80%,陽性13例,陽性率9.9%。
2.3 147例心血管疾病患者CRP、hsCRP異常116例,陽性率78.9%,白細胞計數(shù)>10.0×10^9個/L,中性粒細胞百分比(Neu%)>80%,陽性42例,陽性率28.6%。
3 討論
感染性疾病是易發(fā)的常見病,當機體發(fā)生細菌感染炎癥后6-8小時CRP、hsCRP即可明顯上升。本實驗結果表明,CRP、hsCRP在診斷細菌感染性疾病的敏感性為74.4%(61/82),而在病毒感染或非細菌感染性疾病中,CRP、hsCRP敏感性為6.1%(8/131),這也體現(xiàn)CRP、hsCRP在診斷細菌性感染時特異性較高,CRP、hsCRP在判斷細菌感染與病毒感染中具有重要作用。CRP、hsCRP在診斷心血管疾病的因素敏感性為78.9%(116/147),CRP、hsCRP不僅是心血管疾病的預測因子,也是診斷心血管疾病的重要指標之一。
白細胞計數(shù)及分類是一種傳統(tǒng)診斷細菌感染或病毒感染指標,本實驗顯示在診斷細菌性疾病時WBC比CRP、hsCRP的敏感性較低,由于影響白細胞計數(shù)升高因素較多,還有部分細菌感染時,患者白細胞計數(shù)及分類變化不顯著,無法給臨床提供有價值的信息。而CRP、hsCRP不受任何因素影響,是一種敏感性炎癥標志物。若將白細胞計數(shù)及分類作為細菌感染主要指標,則易造成漏診、誤診,但CRP、hsCRP可早于WBC升高,再結合血常規(guī)檢查,特異性和敏感性大大提高。
