摘要

目的:探讨宏基因组测序(mNGS)技术在新生儿败血症治疗中的应用价值。方法:回顾性分析20121月至20231月在首都儿科研究所新生儿病房住院诊断为新生儿败血症的病历资料,根据是否完善下一代测序NGS检查分为NGS组与非NGS组,比较两组患儿临床表现、实验室炎症指标检查、临床治疗时间。其中,NGS组患儿中比较mNGS和传统病原学检测的检出率,分析NGS组患儿中宏基因组测序结果对临床治疗时间的影响。结果:收集符合标准的患儿共144例,其中非NGS组患儿81例,NGS组患儿63例。两组患儿主要以发热、呼吸困难、血象异常为临床表现,差异均无统计学意义(P>0.05)。实验室检查中,中性粒细胞(NEU)及C-反应蛋白(CRP)等数值差异有统计学意义(P<0.05)。NGS组患儿在整体治疗时间上少于非NGS组,但差异无统计学意义(P>0.05)。NGS组患儿血液阳性检出率为48.57%,痰培养阳性检出率为100%,脑脊液阳性检出率为52.94%,宏基因组测序在3种体液中的检出率均高于传统病原学检测(P<0.05)。与未检出或低置信度结果相比,高置信度宏基因组测序结果40例,检出阳性率63.49%,但在治疗时间上高置信度宏基因组测序结果与其他宏基因组测序结果相比减少(P<0.05)。结论:宏基因组测序高置信度结果对临床治疗具有较高的指导意义。在临床高度怀疑存在感染且传统病原学检测未能明确病原体时,建议应尽早选择宏基因组测序技术。

Abstract

Objective: To explore the application value of macrogenome sequencing technology in the treatment of neonatal sepsis.Methods: Retrospective analysis of the medical records of children diagnosed with neonatal sepsis who were hospitalized in the neonatal ward of the Capital Institute of Paediatrics from January 2012 to January 2023 and divided them into the NGS group and the non-NGS group according to whether they had perfected the NGS examination comparing the clinical manifestations and experimental examinations of the two groups as well as the time of the children's clinical treatment in the two groups. In the NGS group the detection rates of macro-genome sequencing and traditional pathogenicity testing were compared and the impact of macro-genome sequencing results on clinical treatment time was analysed in the NGS group. Results A total of 144 cases of children who met the criteria were collected including 81 cases in the non-NGS group and 63 cases in the NGS group with fever dyspnoea and blood abnormalities as the main clinical manifestations in the two groups P>0.05), and there were statistically significant differences in neutrophils NEU and C-reactive protein CRPin the laboratory tests P<0.05), of which the NGS group had less time in treatment than the non-NGS group. There was less than that of the non-NGS group but there was no statistically significant difference P>0.05. In the NGS groupthe positive detection rate was 48.57% in blood 100% in sputum culture and 52.94% in cerebrospinal fluid and macrogenomic sequencing had a higher detection rate in the three body fluids compared with traditional pathogenetic testing P<0.05. Compared with non-detection or low confidence results high-confidence macrogenome sequencing results in 40 cases had a positive detection rate of 63.49% but the high-confidence macrogenome sequencing results in terms of time to treatment were significantly reduced compared with other macro-genome sequencing results results P<0.05.Conclusion: High-confidence macrogenomic sequencing results are highly indicative of clinical treatment.It is recommended for early selection when there is a high clinical suspicion of infection and the pathogen cannot be identified by conventional aetiology.
