概括
尼古丁胺补充剂显著降低了免疫抑制的固体器官移植接受者 (SOTRs) 中的角质细胞癌 (KC) 发生率. 这种低成本的补充剂被推用于该患者群体的二次KC预防.
科学领域:
- 皮肤病学 皮肤病学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 尼古丁胺 (维生素B3) 已知具有抗紫外线损伤和炎症的化学预防性.
- 它在免疫抑制群体,特别是固体器官移植接受者 (SOTRs) 的有效性仍然不确定,这是由于关于减少角质细胞癌 (KC) 的相互矛盾的研究.
- 这项研究解决了理解尼古丁胺在SOTR二次KC预防中的作用的差距.
研究的目的:
- 评估口服尼古丁胺胺补充剂在降低免疫抑制SOTRs的角质细胞癌 (KC) 发病率方面的有效性.
- 评估二次结果,包括侵袭性平细胞癌 (SCC),SCC in situ (SCCis) 和基底细胞癌 (BCC) 在一年和两年期间.
- 为尼古丁胺作为SOTRs中的化学预防剂提供基于证据的建议.
主要方法:
- 在一个单一的第三级护理机构进行了一项回顾性队列研究.
- 包括的患者是接受口服尼古丁胺胺 (每天两次500毫克) 至少一年的SOTRs.
- 尼古丁胺胺补充剂服用前一年和服用后一年的KC发病率进行了比较,对二次结果进行了一年和两年间隔的分析.
主要成果:
- 在补充剂后的一年内,KC总发病率显著下降,从224例降至121例 (平均减少2.19个KC;p=0.0012).
- 观察到SCC (平均下降1.15; p=0.00081) 和SCCis (平均下降1.37; p=0.032) 的显著减少,但没有BCC (p=0.13).
- 在两年随访的患者中 (n=31),KC发生率从234下降到167 (平均减少2.18个KC;p=0.037).
结论:
- 尼古丁胺胺补充剂显著降低了免疫抑制的SOTRs中的角质细胞癌 (KC) 发生率.
- 这些发现支持尼古丁胺作为一种低风险,低成本的化学预防补充剂,用于减少SOTR中的KC.
- 进一步的研究可能会探索在不同免疫抑制群体中最佳剂量和长期影响.

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...

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
2
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...
