目标:

本研究旨在描述一项为期13年的大规模队列研究中B族链球菌（GBS）菌血症的流行病学特征、临床表现、治疗措施及转归。

方法:

这项回顾性研究纳入了2011年1月1日至2023年12月31日期间，在澳大利亚西悉尼四家大都市医院中获得B族链球菌（GBS）血培养阳性的16岁及以上患者。通过电子病历系统对这些阳性培养病例的详细信息进行了回顾。

结果:

在为期13年的研究期间，共纳入344例GBS菌血症患者。患者中位年龄为65岁，50%的患者年龄≥65岁。在83.1%的患者中识别出已知危险因素，其中以心脏病和糖尿病最为常见。皮肤及软组织感染是最常见的首发表现（32.0%）。妊娠相关感染占病例的相当比例（16.3%）。7天和30天死亡率分别为2.3%和5.2%，其中年龄≥65岁患者的死亡率较高，达9.3%。青霉素类是治疗GBS菌血症及其继发表现最常用的抗生素类别（66.1%）。

结论:

GBS 菌血症最常见于年龄 ≥65 岁的个体或孕妇。尽管总体死亡率较低，但在年龄 ≥65 岁人群中死亡率高出两倍。

Clinical Significance of Antibiotic Resistance

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...

Bacterial Meningitis I: Introduction

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
