概括
瘤坏死因子-α (TNFA) -308A/G单核酸多态性 (SNP) 与阿尔及利亚患者的脏杂种移植排斥 (KAR) 有关. 携带TNFA -308A等位基因的携带者可能面临更高的KAR风险,而携带TNFA -308G的携带者可能面临更低的风险.
科学领域:
- 免疫遗传学 免疫遗传学
- 移植免疫学 移植免疫学
- 拒绝的遗传学 拒绝的遗传学
背景情况:
- 瘤坏死因子-α (TNFA) -308A/G单核酸多态性 (SNP) 和脏杂种移植排斥 (KAR) 之间的关联仍然不清楚.
- 了解遗传倾向可以帮助管理移植后并发症.
研究的目的:
- 在阿尔及利亚患者队列中调查TNFA-308A/G SNP与KAR的关联.
- 为了确定预测KAR风险的潜在遗传标记.
主要方法:
- 一项追溯病例控制研究,涉及313名阿尔及利亚参与者:58名脏移植接受者没有排斥 (PWoR),58名排斥 (PWR) 和197名健康人 (HI).
- 使用实时聚合酶链反应进行了TNFA-308A/G SNP的基因定型.
主要成果:
- 与HI和PWoR组相比,PWR组的TNFA -308A等位基因和AA基因型频率明显高于HI和PWoR组.
- 相反,TNFA -308G等位基因的频率在PWR组中低于PWoR和HI组.
- 这些关联在PWR患者中特别明显,这些患者具有新的抗人类白细胞抗原 (HLA) 抗体.
结论:
- 在阿尔及利亚脏移植接受者中,TNFA -308A/G多态性与KAR有关.
- 携带TNFA-308A等位基因的携带者,特别是那些具有抗HLA抗体的人,可能会增加KAR的风险.
- TNFA -308G等位基因携带者可能对KAR有保护作用,这表明基因型导向治疗策略的潜力.

Kidney Transplant I: Introduction
28
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

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.
