概括
在全球范围内,白疹免疫力正在下降,只有不到一半的人口受到保护. 这种重新出现的疫苗可预防的疾病需要紧急的公共卫生关注和补充疫苗接种战略.
科学领域:
- 免疫学 免疫学 免疫学
- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 脊髓灰质炎是严重的公共卫生问题,因为它再次成为疫苗可以预防的感染.
- 评估全球血清IgG抗白血病抗体水平对于识别易感人群至关重要.
研究的目的:
- 估计全球人口中保护性IgG抗白血病抗体的综合血清流行率.
- 为了确定影响全球白病血清保护率的因素.
主要方法:
- 在三个数据库中进行了系统的文献搜索,直到2023年5月.
- 包含的研究报告了血清抗白血病抗体标位> 0.1 IU/ml作为血清保护.
- 使用NHLBI检查清单进行质量评估,并从统计学上解决异质性问题.
主要成果:
- 在1720篇获取的文章中,有51篇被纳入了元分析.
- 最初的综合血清阳性率为57%,在删除异常值后调整为51%.
- 血清发病率随着年龄的增长而下降,并且在地理上有所不同,西太平洋和非洲地区的发病率较低.
- 在2015年之后,二菌血清保护显著下降,在2016-2023年期间降至45.75%
结论:
- 自2015年以来,全球白喉血清保护率已下降到50%以下,这表明疾病正在重新出现.
- 全球人口的很大一部分不再对白喉病有血清保护.
- 建议通过补充接种疫苗加强白喉免疫力,先进行抗体标位查.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Therapeutic Drug Monitoring: Drug Analysis Methods
342
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Diphtheria
175
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
