概括
肝移植 (LT) 后的低母球蛋白血症 (HGG) 是常见的. 移植前的HGG,而不是肝病的严重程度 (MELD得分),对LT后的死亡风险产生重大影响.
科学领域:
- 免疫学
- 肝病学
- 移植科学
背景情况:
- 肝移植 (LT) 后的一个常见并发症是低球蛋白血症 (HGG).
- 肝移植前肝病严重程度对LT后免疫球蛋白水平的影响尚不清楚.
- 了解这些动态对于治疗移植后并发症至关重要.
研究的目的:
- 研究移植前的肝病末期模型 (MELD) 评分和LT后的血清免疫球蛋白G (IgG) 水平之间的关系.
- 评估LT后HGG的发病率及其与临床结果的关联,特别是死亡率.
- 确定MELD评分是否影响肝移植后的免疫球蛋白动态.
主要方法:
- 在2016年7月至2022年12月期间接受LT的患者的回顾性分析.
- 使用倾向性匹配来比较低和高MELD分数组.
- 在不同时间点 (LT前,1个月,6个月,1年后) 评估血清IgG水平,并评估HGG发生率和死亡率.
主要成果:
- 从LT前 (1,606. 5 mg/ dL) 到LT后1个月 (1,011. 6 mg/ dL) 的血清IgG水平显著下降.
- 在移植后的任何时间点,低MELD和高MELD组之间没有发现IgG水平的显著差异.
- 36. 0% 的患者在LT后的一年内出现HGG,而LT前的HGG与死亡率的增加独立相关.
结论:
- 肝移植后的移植前期常见的并发症.
- 移植前的HGG,而不是MELD得分显示的潜在肝病的严重程度,是死亡率的重要预测因素.
- 肝病的严重程度 (MELD评分) 没有显著影响HGG发育或LT后的免疫球蛋白动态.

Transcytosis of IgG
2.9K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Kidney Transplant III: Nursing Management
81
Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Kidney Transplant I: Introduction
60
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...
