概括
接种COVID-19疫苗对肝移植接受者来说是安全的. 该研究发现BNT162b2接种疫苗后没有增加氨酸转氨酶 (ALT) 或肝活检的风险,确保了这种脆弱人群的疫苗安全性.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 免疫学 免疫学 免疫学
- 移植手术 移植手术
背景情况:
- 肝移植 (LTx) 接受者面临COVID-19的风险增加.
- 疫苗接种对于缓解LTx患者严重后果至关重要.
- 人们对疫苗潜在的副作用存在担忧,例如阿氨酸酶 (ALT) 的升高,可能导致肝脏活检的增加.
研究的目的:
- 确定在BNT162b2接种疫苗之前和之后在LTx接种者中ALT升高的流行率和相对发病率.
- 评估BNT162b2接种疫苗后LTx接种者肝脏活检患病率的变化.
主要方法:
- 利用了393名LTx接受者在丹麦肝移植接受者共患病率 (DACOLT) 研究中的数据.
- 在每个BNT162b2疫苗剂量周围计算了ALT升高和肝脏活检的患病率.
- 用人自我控制病例系列 (SCCS) 分析来评估疫苗接种和ALT升高之间的关联.
主要成果:
- 在每个疫苗剂量周围,ALT升高的患病率仍然相当.
- 接种疫苗后没有观察到ALT升高的相对发病率增加.
- 肝活检的患病率在接种疫苗期间没有显著变化.
结论:
- 接种BNT162b2疫苗似乎不会增加ALT升高的风险,也不需要在肝移植接受者中更频繁的肝活检.
- 这些发现支持在这个免疫力低下的人群中接种COVID-19疫苗的安全性.
- 对管理LTx接种者的临床医生来说,关于与疫苗相关的肝酶变化的数据令人放心.

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...

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...
