概括
移植后免疫性球瘤病变 (ITG) 的复发是常见的. 这一案例凸显了在Rituximab由于B细胞数量低而无效时管理ITG复发的挑战.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 移植免疫学 移植免疫学
- 淋巴细胞疾病 淋巴细胞疾病
背景情况:
- 免疫性球性球症 (ITG) 是一种罕见的疾病,导致球体中的蛋白质沉积,可能导致功能衰竭和末期病 (ESRD).
- 移植后ITG复发影响超过50%的患者,由于病例报告稀缺,已建立的治疗方案有限.
研究的目的:
- 报告移植后免疫性球细胞病变复发的情况.
- 讨论在免疫抑制和B细胞枯竭的背景下对复发性ITG的管理挑战和潜在的治疗考虑.
主要方法:
- 一名58岁的男性患有蛋白尿和肌水平升高,接受了脏活检,最初诊断出患有膜增殖性球球腺炎,暗示ITG.
- 患者因功能不良而接受Rituximab,没有改善,进展为ESRD,并接受了移植.
- 移植后,由于蛋白尿,通过活检诊断出复发性ITG,尽管CD19阳性B细胞计数为零,但排除了进一步的rituximab管理.
主要成果:
- 患者经历了移植后五个月的ITG复发,尽管标准的抗排斥疗法 (塔克罗利斯,mycophenolate mofetil,普雷尼松酸盐).
- 目前的功能显示出相对稳定的肌水平 (120-150 mmol/L),蛋白尿持续超过正常范围.
- 患者的CD19阳性B细胞计数无法检测,这表明B细胞枯竭和无法重新给予Rituximab.
结论:
- 这一案例凸显了管理ITG复发的困难,特别是当之前的B细胞消耗疗法使得进一步使用这些药物成为不可能时.
- 这些发现有助于对移植后ITG复发的有限文献,为未来的治疗策略和患者管理提供了见解.

Overview
Tissue Transplantation
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.

Kidney Transplant I: Introduction
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...
Kidney Transplant II: Surgical Procedure
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 donor...
Kidney Transplant III: Nursing Management
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...
