背景情况:

重症综合免疫缺陷 (SCID) 的新生儿查 (NBS) 依赖于T细胞受体切除循环 (TREC).
假阳性结果是SCID NBS的一个重大挑战,特别是在早产婴儿中.
目前的查实践可能会导致脆弱人群不必要的后续程序.

研究的目的:

评估TREC值和SCID查结果,特别是在早产新生儿中.
确定基于证据的SCID查实践,尽量减少早产婴儿的错误阳性.
为在低出生体重和早产人口中优化SCID NBS提供建议.

主要方法:

Immunodeficiency Diseases

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Development of Immunocompetence

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
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.
Subsequent T...
