血清降钙素原(PCT)测定在感染性疾病病原鉴别诊断中的应用价值探讨

Serum Procalcitonin (PCT) Was Measured in Infection Application Value of Differential Diagnosis of Disease Pathogen

目的:探讨血清降钙素原(PCT)检测在感染性疾病病原鉴别诊断中的应用价值。方法:回顾性收集本院临床各科室2017年1月至2017年9月收治的86例血培养阳性或九项呼吸道病原监测为阳性的感染性疾病患者,分析血清PCT检测在病原学鉴别诊断中的应用价值。结果:革兰阴性菌组PCT水平最高,其次为革兰阳性菌组,两组间比较有显著性差异,但该两组与其它4组比较均有非常显著性差异;真菌组与支原体组及Q热立克次体组三组PCT水平相当,三组间比较无显著性差异;病毒组PCT水平最低,与其余5组比较均有非常显著性差异。结论:血清PCT检测在感染性疾病病原早期鉴别诊断中有一定的应用价值,在病原学结果未获得前,可依据PCT水平推断可能感染的病原体,并给予相应的抗感染治疗。

Objective: To explore significance of serum calcitonin (PCT) in the differential diagnosis of infectious diseases. Methods: A retrospective study was performed on 86 patients with infectious diseases who had received positive blood culture or nine respiratory tract pathogens in the clinical departments of our hospital from January 2017 to September 2017. Results: The PCT level of gram-negative bacteria group was the highest, followed by gram-positive bacteria group. There were significant differences between the two groups, but there were significant differences between the two groups and the other four groups. The level of PCT in the fungal group was similar to that in the mycoplasma group and the Q thermoplastic group, but there was no significant difference between the three groups. The PCT level of the virus group was the lowest, which was significantly different from that of the other 5 groups. Conclusion: The detection of serum PCT has certain significance in early differential diagnosis of infectious diseases. Before the results of pathogenic are obtained, the infected pathogens may be inferred according to the level of serum PCT and made the corresponding anti-infection treatment.
