概括
在固体器官移植 (SOT) 接受者中,COVID-19疫苗接种并没有降低白细胞计数. 然而,SARS-CoV-2感染与这些脆弱患者白细胞计数下降的风险更高有关.
科学领域:
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
- 移植 移植 移植 移植
背景情况:
- 固体器官移植 (SOT) 接受者面临严重的COVID-19风险.
- 接种疫苗至关重要,但可能会导致副作用,如白细胞数量下降.
- 了解SOT接受者的这些影响至关重要.
研究的目的:
- 评估SARS-CoV-2 mRNA接种疫苗后白细胞数量下降的流行率和发病率. 在SOT接种者中.
- 为了比较疫苗接种后白细胞计数变化与SARS-CoV-2感染.
- 评估疫苗接种/感染与白细胞数量下降之间的关联.
主要方法:
- 线性混合模型分析了疫苗剂量前后白细胞计数变化.
- 血白细胞数量下降的患病率是在疫苗接种前和后以及感染前和后确定的.
- 自控病例系列分析评估了疫苗接种或感染后白细胞数量下降的风险.
主要成果:
- 在228名SOT接种者中,接种疫苗并没有改变白细胞计数或其患病率.
- 在SARS-CoV-2 mRNA疫苗接种和白细胞数量下降之间没有发现任何关联 (IRR:0.6;P=0.461).

Disorders of Leukocytes

Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
