乙组链球菌 (GBS) 阳性,以及产妇内抗生素预防 (IAP),与降低胆膜炎的风险有关. 这种保护性关联随着妊娠年龄的增加而变得更加明显,特别是在40周后.
科学领域:
- 产科和妇科 产科和妇科
- 传染性疾病 传染性疾病
- 新生儿健康 新生儿健康
背景情况:
- 乙组链球菌 (GBS) 查和产后抗生素预防 (IAP) 是标准的做法.
- 之前的研究表明,GBS殖民可能与较低的胆膜炎风险有关,可能是由于IAP的保护作用.
研究的目的:
- 为了证实GBS殖民和减少胆膜炎风险之间的关联.
- 评估这种关联是否随着分娩时的妊娠周而变化.
主要方法:
- 在2005年至2021年期间,对超过155,000次单期分娩的回顾性队列研究.
- 基于ICD-10代码在GBS阳性患者与GBS阴性患者中的临床胆炎诊断的分析.
- 在分娩时按妊娠周对结果的分层.
主要成果:
- 与GBS阴性患者相比,GBS阳性患者的胆 ?? 膜炎诊断的可能性降低了21% (1.5%对2.2%).
- 在GBS阳性和阴性群体之间的胆膜炎率的差异随着妊娠年龄的增长而增加.
- 在GBS阳性个体中,胆膜炎的风险保持稳定,但在41-42周妊娠时,在GBS阴性个体中显著增加.
结论:
- 在具有通用GBS查和IAP的环境中,GBS阳性与较低的胆 ?? 膜炎风险有关.
- 这种保护作用似乎是由40周以后GBS阴性患者中胆 ?? 膜炎的发病率增加所驱动的.
- 怀孕年龄是GBS状态和胆膜炎风险之间的关系的一个关键因素.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
