概括
在早产新生儿中,预防性颗粒细胞-巨细胞殖民地刺激因子 (GM-CSF) 纠正中性缺陷,但不会减少败血症或改善存活率. 这项研究没有发现极度早产婴儿无败血症生存的显著益处.
科学领域:
- 新生儿医学 新生儿医学
- 儿科血液学 儿科血液学
- 新生儿感染性疾病 新生儿感染性疾病
背景情况:
- 系统性败血症是早产新生儿死亡的主要原因.
- 理论上,血造细胞殖民地刺激因子被提出可以减少败血症并改善结果.
- 目前在新生儿医学中使用这些药物缺乏强有力的证据.
研究的目的:
- 评估粒细胞 - 巨细胞殖民地刺激因子 (GM-CSF) 预防是否可降低高危中性衰竭的早产儿的败血症,死亡率和发病率.
- 评估GM-CSF在改善这种脆弱人群的无败血症生存率方面的疗效.
主要方法:
- 一个单盲,多中心,随机对照试验,涉及280名新生儿 (怀孕期≤31周,出生体重<第10个百分点).
- 参与者每天接受皮下GM-CSF5天或在出生后72小时内接受标准管理.
- 主要结局是无败血症生存到14天,并进行治疗意图分析.
主要成果:
- 与对照组相比,在最初的11天内,转基因-CSF治疗导致中性粒细胞数量显著更快地增加.
- 在GM-CSF治疗组和对照组之间没有观察到无败血症生存时间的显著差异 (-8%的差异,95%CI -18至3).
- 对这项和之前的试验的元分析表明,预防性GM-CSF没有生存益处.
结论:
- 早期产后预防性GM-CSF有效地纠正极度早产新生儿的中性质缺陷.
- 然而,它并没有显示出败血症发病率的减少或生存率和短期结果的改善.
- 这些发现不支持在这个人群中常规使用预防性GM-CSF.

Differentiation of Common Myeloid Progenitor Cells
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
