谨慎处理报告的抗生素过敏是抗生素管理的一个重要方面。荷兰抗生素政策工作组（SWAB）于2023年4月发布了《SWAB指南：疑似抗生素过敏的处理方法》以下简称（指南）,指南依据对疑似抗生素过敏人群的比较和结果问题研究,对每个问题进行系统的文献检索,并通过证据评价系统对现有最佳证据进行审查后制定。指南就疑似抗生素交叉过敏,速发型过敏和迟发型过敏等问题进行阐述,为报告抗生素过敏患者选用抗生素治疗的床旁决策提供基于现有研究的循证建议。本文对指南涉及12个关键问题进行解读,以期为疑似抗生素过敏患者临床治疗提供参考,使患者获益。

Careful handling of reported antibiotic allergies is an important aspect of antibiotic management．In April 2023,the Dutch Working Group on Antibiotic Policy（SWAB）issued the SWAB Guide：“The Dutch Working Party on Antibiotic Policy（SWAB）guideline for the approach to suspected antibiotic allergy”,hereinafter referred to as “the guide”．According to the intervention,comparison and results of people with suspected antibiotic allergy,the guide systematically searched the literature of each question,and was formulated after reviewing the best evidence available through the evidence evaluation system．The guide elaborated on the suspected cross-allergy,quick-onset allergy and delayed-onset allergy,and selected antibiotics for reporting patients with antibiotic allergy．In this paper,12 key issues involved in the guidelines are interpreted in order to provide reference for clinical treatment of patients suspected of antibiotic allergy and benefit patients．

目的 探究与分析化脓性阑尾炎抗生素治疗后不同时机腹腔镜阑尾切除术的疗效及预后。方法 研究于2019年1月—2021年1月进行,我院收治的96例化脓性阑尾炎患者为此研究的参与对象,接受抗生素治疗≤72 h后手术的患者为观察组(n=38),>72 h的患者为对照组(n=38)。对比2组患者的指标。结果 2组的手术时间等相较均无差异(P>0.05);观察组的住院时间及住院费用均短于或少于对照组(P<0.05)。观察组术前中性粒细胞比例及白细胞计数高于对照组(P<0.05);术后2组患者组间无差异(P>0.05)。观察组的腹腔渗液阳性率低于对照组(P<0.05)。2组并发症发生率比较,组间无差异(P<0.05)。结论 化脓性阑尾炎患者经抗生素治疗后续尽早接受手术治疗。

目的 观察低出生体重早产儿应用抗生素后肠道菌群的动态变化。方法 选取2018年6月—2019年7月在广州市第一人民医院住院的10名低出生体重早产儿,在出生时、出生后1~2周、出生后2~3周、出生后3~4周、出生后4~5周、出生后5~6周时分别收集粪便样本,通过16s高通量测序检测患儿粪便菌群变化并统计分析。结果 应用抗生素后的低出生体重早产儿肠道菌群α多样性(Shannon指数、Simpson指数、ACE指数和PD_whole_tree指数)下降(P均<0.05),肠道菌群结构在门、科、属水平均发生改变,其中Alistipes、Bacteroides、Lactobacillus、unidentified_Lachnospiraceae、unidentified_Ruminococcaceae、Alloprevotella、unidentified_Cyanobacteria、Bacillus、Stenotrophomonas和Acinetobacter菌属相对丰度减少(P均<0.05)。结论 低出生体重早产儿应用抗生素后肠道菌群多样性下降,肠道菌群结构发生改变,并在抗生素停用后仍持续,针对性补充益生菌或益生元可能有助于肠道菌群恢复稳态。

Objective To observe the dynamic changes of gut microbiota in premature infants with low birth weight after antibiotics therapy. Methods 10 low birth weight premature infants hospitalized in Guangzhou First People's Hospital from June 2018 to July 2019 were included. Fecal samples were collected at birth, 1~2 weeks after birth, 2~3 weeks after birth, 3~4 weeks after birth, 4~5 weeks after birth and 5~6 weeks after birth, respectively. The changes of fecal microbiota were detected and analyzed by 16s high-throughput sequencing. Results The α-diversity of gut microbiota (Shannon index, Simpson index, ACE index and PD_whole_tree index) in low birth weight preterm infants treated with antibiotics decreased (P<0.05). The structure of gut microbiota changed at phylum, family and genus levels, among which Alistipes, Bacteroides, Lactobacillus, unidentified_Lachnospiraceae, unidentified_Ruminococcaceae, Alloprevotella, unidentified_Cyanobacteria, Bacillus, Stenotrophomonas and Acinetobacter decreased (P<0.05). Conclusion The diversity of gut microbiota in low birth weight preterm infants decreased and the structure of gut microbiota changed after antibiotic therapy. Targeted supplementation of probiotics or prebiotics may contribute to the recovery of gut microbial homeostasis.

目的 了解中山市儿童社区获得性肺炎病原学特点及其与年龄、抗生素使用的相关性,为疾病诊断和抗生素合理使用提供参考依据。方法 对中山市妇幼保健院儿科住院部2016年1月—2016年4月收治的小儿社区获得性肺炎临床资料、入院前使用抗生素和病原学检测结果进行回顾性分析。结果 共有155例研究对象纳入研究,细菌检出95株,其中革兰氏阴性菌61株,革兰氏阳性菌34株。流感嗜血杆菌,金黄色葡萄球菌,肺炎链球菌,大肠埃希氏菌,副流感嗜血杆菌的占构成比前五位。支原体和衣原体现症感染率约7.7%～8.4%。RSV检出率达25.8%。年龄在3 a以上、入院前使用过抗生素者,革兰阳性菌检出率较低(P<0.05)。入院前使用过抗生素者,革兰阴性菌检出率较高,且使用4 d及以上者高于使用3 d及以下者(P<0.05)。结论 住院儿童CAP的治疗,应综合考虑病人的年龄、入院前的抗生素使用情况,结合当地CAP 的可能优势病原选择合适的治疗方案。

Objective To explore the etiological characteristics and factors of community-acquired pneumonia(CAP) in children in Zhongshan for providing reference for the diagnosis and rational use of antibiotics for CAP. Methods Retrospective analysis were applied on clinical data and etiology results of CAP in children admitted to the pediatric inpatient department of Maternal and Child Health Hospital in Zhongshan from January to April, 2016. Results 155 children were enrolled. The number of bacteria detected was 95, including 61 Gram-negative bacteria, 34 Gram-positive bacteria. Haemophilus influenzae, Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli, Haemophilus parainfluenzae accounted the top five. The recent infection rate of Mycoplasma and Chlamydia were from 7.7% to 8.4%. RSV detection rate was 25.8%.The Children who were over 3 years old, pre-use of antibiotics, associated with lower detection rate of Gram-positive bacteria (P<0.05). The Children who were the pre-use of antibiotics, associated with higher detection rate of Gram-negative bacteria, and the use of four days and more higher than three days or less(P<0.05). Conclusion For the treatment of CAP in children, the patient's age and pre-use history of antibiotics should be considered, combined with local common type of disease pathogens, to select the appropriate treatment.
