概括
患有慢性淋巴细胞白血病/小淋巴细胞淋巴瘤 (CLL/SLL) 和二次免疫缺陷疾病 (SID) 的患者面临更高的感染风险. 免疫球蛋白替代疗法 (IgRT) 可能表明更脆弱的人群需要进一步研究.
科学领域:
- 血液学 血液学 血液学
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
背景情况:
- 患有慢性淋巴细胞白血病/小淋巴细胞淋巴瘤 (CLL/SLL) 的患者经常患上二次免疫缺陷疾病 (SID).
- 在CLL/SLL患者中,SID增加了对严重,复发或持久感染的易感性.
- 了解患有和没有SID的CLL/SLL患者的感染负担至关重要.
研究的目的:
- 评估患有CLL/SLL的患者的感染负担,比较患有和没有SID的患者.
- 通过免疫球蛋白替代疗法 (IgRT) 用来分层评估SID的CLL/SLL患者的感染率和医疗资源利用率 (HCRU).
主要方法:
- 使用匿名的美国Optum-Humedica数据进行回顾性队列研究 (2015年10月~2020年3月).
- 确诊的CLL / SLL诊断的18岁以上的患者根据IgG水平,诊断码和主要感染被分为SID和非SID队列.
- 根据IgRT治疗状态进一步分类SID患者.
主要成果:
- 与没有SID的患者相比,患有CLL/SLL和SID的患者的感染率显着更高 (70.1%vs30.4%).
- 严重的细菌感染 (39.8%与9.2%) 和因感染住院的病例 (27.7%与5.8%) 在SID队列中更为频繁.
- SID队列具有更高的抗感染药物使用,HCRU和更短的整体存活期 (12.3个月与16.9个月). 患有SID的IgRT治疗患者表现出更大的感染负担和HCRU.
结论:
- 二次性免疫缺陷疾病显著增加了CLL/SLL患者的感染负担,医疗保健利用率和死亡率.
- 在患有SID的CLL/SLL患者中使用免疫球蛋白替代疗法可能表明需要进一步调查的更易受伤害的亚组.
- 需要进一步的研究来指导IgRT的使用,并评估其在高风险人群中的益处.

Immunodeficiency Diseases
923
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.

Pulmonary Tuberculosis I
225
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Disorders of Leukocytes
910
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...

Cells of the Adaptive Immune Response
971
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
