概括
像mycophenolate和tacrolimus这样的免疫抑制药物可能会增加移植接受者 (KTR) 的癌症风险. 风险因年龄和性别而异,这表明需要个性化免疫抑制策略来缓解癌症的发展.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 移植接受者 (KTR) 通常需要长期免疫抑制.
- 当代免疫抑制剂对于移植的生存至关重要,但可能与二次癌症有关.
- 了解普得尼松,酸和塔克罗利斯等药物的特定风险对于患者管理至关重要.
研究的目的:
- 调查当代免疫抑制剂的累积剂量与KTR癌症发病率之间的关联.
- 为了确定这些关联是否根据患者的年龄和性别而有所不同.
- 探索暴露近期对癌症风险的影响.
主要方法:
- 初级KTR (1997-2016) 的回顾性队列研究.
- 多变量Cox模型用于评估累积免疫抑制剂 (普雷尼松,酸,塔克罗利斯) 和原发性恶性瘤 (PMN) 之间的关联.
- 权重累积暴露 (WCE) 建模评估了暴露的近期;评估了与年龄和性别的相互作用.
主要成果:
- 在1064名KTR中,108名 (10.2%) 患有PMN.
- 累积的塔克罗利斯暴露显示PMN风险增加,特别是在年轻的KTR (15岁和30岁).
- 较高的累积mycophenolate剂量与PMN风险的增加有关,PMN风险在女性中更为明显,特别是在5-10年前暴露时.
结论:
- 长期暴露于甲酸和塔克罗利斯可能会增加KTR的癌症风险.
- 年龄和性别改变了这些风险,年轻的KTR和女性可能更容易受到分别的塔克罗利和酸的影响.
- 量身定制的免疫抑制策略是有必要的,以尽量减少脏移植接受者的癌症风险.

Pulmonary Tuberculosis I
243
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.

Tissue Transplantation
366
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
