降钙素原检测在新生儿感染性疾病中的应用(1)
[摘要] 目的 探讨血清降钙素原(PCT)在新生儿感染性疾病应用价值。方法 将该院儿科2013年12月—2014年12月收治的288例住院新生儿分别归入重症感染组(64例)、一般感染组(132例)、非感染组(92例)，采用电化学发光法检测患儿血清降钙素原(PCT)水平变化。结果 一般感染组132例，降钙素原阳性46例，阳性率34.85%，阴性86例；重症感染组64例，降钙素原阳性40例，阳性率62.5%，阴性24例；非感染组92例，降钙素原阳性9例，阳性率9.78%，阴性83例。重症感染组PCT阳性率最高，一般感染组其次，非感染组阳性率最低，差异有统计学意义(P<0.05)；所有患儿血清降钙素原值随病情的好转而降低，差异有统计学意义(P<0.05)。结论 ①通过检测288例患儿血清PCT水平可以明确患儿的感染情况，可有效鉴别细菌感染；②新生儿肺炎有多种病因，并非细菌感染一种，PCT检测可作为新生儿感染性肺炎的鉴别指标，为临床合理使用抗生素提供理论依据。

[Abstract] Objective To investigate the value of serum procalcitonin(PCT) applied to neonatal infectious diseases. Methods 288 neonates hospitalized in Department of Pediatrics of our hospital from December 2013 to December 2014 were divided into severe infection group (64 cases)， general infection group (132 cases)， non-infected group (92 cases). Electrochemical luminescence method was used to test the level of serum PCT in the neonates. Results Of the 132 cases in the general infection group， 46 cases had positive procalcitonin with the positive rate of 34.85%， 86 cases had negative procalcitonin. Of the 64 cases in the severe infection group， 40 cases had positive procalcitonin with the positive rate of 62.5%， 24 cases had negative procalcitonin. Of the 92 cases in the non-infected group， 9 cases had positive procalcitonin with the positive rate of 9.78%， 83 cases had negative procalcitonin. The severe infection group had the highest positive rate of PCT， followed by the general infection group， and the non-infected group had the lowest positive rate of PCT with statistically significant difference(P<0.05). The level of PCT in all the neonates decreased as the disease improved with statistically significant difference(P<0.05). Conclusion ①The infection of the neonates and bacterial infection can be effectively identified by testing the level of serum PCT in 288 neonates. ②Many reasons including bacterial infection can cause neonatal pneumonia. PCT testing can be used as the identification index of neonatal infectious pneumonia， which provides a theoretical basis for the clinical rational use of antibiotics.
