概括
患有多发性骨髓瘤和二次免疫缺陷的患者面临更高的感染风险. 免疫球蛋白替代疗法可能表明更脆弱的患者群体,突出需要更好地了解二次免疫缺陷负担.
科学领域:
- 血液学 血液学 血液学
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
背景情况:
- 患有二次免疫缺陷 (SID) 的多发性骨髓瘤 (MM) 患者容易感染.
- 疾病进展和治疗毒性加剧了MM患者的感染风险.
研究的目的:
- 评估MM患者和没有SID的感染负担.
- 为了比较接受免疫球蛋白替代疗法 (IgRT) 的MM患者与不接受免疫球蛋白替代疗法 (IgRT) 的SID患者之间的结果.
主要方法:
- 使用匿名的美国索赔数据进行回顾性队列研究 (2015年10月至2020年3月).
- 18岁以上的MM患者根据IgG水平,诊断码和主要感染被分为SID和非SID队列.
- SID患者进一步分为IgRT和非IgRT组.
主要成果:
- 与没有SID队列相比,SID队列的感染率 (58.9%对31.3%),严重感染率 (29.8%对10.6%) 和与感染有关的住院病例 (26.9%对9.1%) 显着更高.
- 细菌感染最常见,特别是在SID队列 (49.2%) 和IgRT亚组 (70.4%).
- 在SID队列中,整体存活时间较短 (12.6个月),而非SID队列 (14.7个月).
结论:
- 患有SID的MM患者经历了较高的感染负担和较差的生存率.
- 接受IgRT的SID患者的感染率增加表明,这一亚组代表了一个更脆弱的人群.
- 改善SID的理解和管理对于改善多发性骨髓瘤患者的治疗结果至关重要.

Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

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.

Pulmonary Tuberculosis I
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.
