概括

与原性免疫缺陷相关的淋巴增殖性疾病 (OIIA-LPDs) 的自发回归与更好的生存率有关. 埃普斯坦-巴尔病毒 (EBV) 编码的RNA在位杂交 (EBER-ISH) 和可溶性互白素-2受体 (sIL-2R) 水平预测回归.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
病毒学病毒学

背景情况:

其他有毒性免疫缺陷相关的淋巴增殖性疾病 (OIIA-LPD) 与用于自身免疫疾病的免疫抑制药物 (ISD) 使用有关.
爱斯坦-巴尔病毒 (EBV) 感染是OIIA-LPD发展的一个可疑因素.
在ISD停止后OIIA-LPD自发回归 (SR) 的预测因子尚未确定.

研究的目的:

为了研究OIIA-LPD患者的临床特征.
确定与治疗反应,预后和自发回归 (SR) 相关的因素.
评估埃普斯坦-巴尔病毒 (EBV) 编码的RNA在位杂交 (EBER-ISH) 和可溶性互白素-2受体 (sIL-2R) 水平对SR的预测值.

主要方法:

在2002年至2022年期间,对82名被诊断患有OIIA-LPD的患者进行了回顾性观察研究.
对临床数据的分析,包括治疗反应,预后和ISD停药后的SR.
评估EBV编码RNA在位杂交 (EBER-ISH) 和可溶性互白素-2受体 (sIL-2R) 的水平.

主要成果:

50%的患者在停止免疫抑制药物后实现了自发回归 (SR).
所有患者的5年整体存活率为86.3%,SR组 (96.9%) 与非SR组 (77.2%) 相比显著更高.
多变量分析确定了积极的EBER-ISH结果和低的sIL-2R水平作为SR的显著预测因素 (分别P=0.016和0.012).

结论:

自发回归 (SR) 与OIIA-LPD患者的整体存活时间 (OS) 显著延长有关.
爱斯坦-巴尔病毒 (EBV) 编码的RNA在位杂交 (EBER-ISH) 阳性和低可溶性互白素-2受体 (sIL-2R) 水平是SR的关键预测因素.
这些发现有助于理解OIIA-LPD预后,并指导治疗决策.

Immunodeficiency Diseases

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.
There are three main causes of immunodeficiency...

Pulmonary Tuberculosis I

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.
Mode of...
