|December 4, 1982
まとめ
移植前のT細胞の反応性があり,移植時にクロスマッチが陰性であった腎臓移植受容者は,1年後に60%の移植生存率を持っていた. これは,T細胞の事前の感受性にもかかわらず,成功した移植が可能であることを示唆しています.
科学分野:
- ネフロロジーはネフロロジーを用います.
- 免疫学 免疫学とは
- 移植医学 移植医学について
背景:
- 陽性なT細胞クロスマッチは,腎臓移植の拒絶のリスクが高いことを示します.
- 移植前のT細胞反応性の臨床的意義は不明であるが,移植時に存在しない.
研究 の 目的:
- 移植前のT細胞反応性があり,移植時にクロスマッチが陰性であった高度に敏感な患者の移植生存を評価する.

- 患者はアザチオプリン,プレドニゾーン,ウサギの抗チモサイト血清で免疫抑制を受けた.
- 移植後,少なくとも1年間のフォローアップ.
主要な成果:
- 患者の60% (9/15) は,平均血清クレアチニン値1.6mg/dLの機能する移植を維持しました.
- 早期の移植機能不全は12人の患者で発生しました.
- 早期の急性ユーモラル拒絶 (1) と慢性拒絶 (2) に起因する移植の喪失が発生しました.
- 14人の患者は,移植前の正常なリンパ球に対するT細胞の反応性の低下を示した.

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...
