概括
患有天生的免疫缺陷 (IEI) 的患者面临更高的COVID-19住院和死亡风险,尤其是成年人. 早期干预,如免疫球蛋白治疗和康复期血,可能会改善这些脆弱人群的结果.
科学领域:
- 免疫学
- 传染性疾病
- 遗传学
背景情况:
- 天生的免疫错误 (IEI) 与COVID-19患者的严重临床结果有关.
- 了解IEI患者住院,ICU入院和死亡的特定风险对于临床管理至关重要.
研究的目的:
- 确定COVID-19相关住院,ICU入院和IEI患者死亡的危险因素.
- 在IEI患者群体中分析COVID-19的临床特征和结果.
主要方法:
- 62名被诊断为IEI的COVID-19患者 (29名儿童,33名成年人) 的回顾性分析.
- 数据收集包括人口统计,IEI类型,临床表现,实验室标志物 (D-二次体,费里丁),并发症和接受的治疗.
- 统计分析以确定住院和重症监护室的风险因素.
主要成果:
- 成人住院率 (21/33) 比儿童 (11/29) 高.
- 咳,提升的D-二聚合物和费里丁水平与住院有关.
- 免疫球蛋白替代疗法和咳是住院风险的重要预测因素.
- 较高的费里水平与重症监护室入院相关.
- 总体死亡率为6. 5%,明显高于一般人群,没有儿童死亡.
- 艾格玛格洛布林血症的急诊率很高,突出显示了粘膜IgA在COVID-19防御中的作用.
结论:
- IEI患者,特别是成年人,患有严重COVID-19的风险增加.
- D-二聚合物和费里丁水平升高是严重疾病和住院风险的指标.
- 康复性血治疗可能会缩短特定IEI类型的住院时间,如AGAMMAGLOBULINEMIA.

Factors Affecting the Risk of Infection
12.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Development of Immunocompetence
448
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...

Active versus Passive Immunity
3.7K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.

Immunodeficiency Diseases
1.2K
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.

Introduction to Innate and Adaptive Immunity
5.2K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Immune Response Against Viral Pathogens
917
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
