- 腎臓科
- 移植医学
背景
- 腎臓移植患者の高い心血管疾患と死亡率は持続しています.
- 動脈静脈 (AVF) は,移植後の心血管再形成に寄与する可能性があります.
- AVFの結合がこの改造を逆転させる可能性は不明です.
研究 の 目的
- 安定した腎臓移植を受けた患者の心臓の構造と機能に対するAVF結合の効果を評価する.
- AVFの結合が心血管の改造を逆転させられるかどうか
主な方法
- 移植後の安定した腎臓機能 (> 12ヶ月) を含むランダム化制御試験.
- 参加者はAVF結合または無介入にランダムに割り当てられました.
- 心臓の磁気共鳴画像は, left ventricular (LV) の質量,体積,心房領域,射出分数,NT-proBNP,心臓出力,および腕の流れを評価するために,初期および6ヶ月間使用されました.
主要な成果
- AVF結合は,対照群のわずかな増加と比較して,LV質量を22. 1g大幅に減少させた (P<0. 001).
- LV量,心臓出力,心房量,NT-proBNP濃度 (P<0. 01) の有意な減少が観察されました.
- 肺動脈の射出分数や肺動脈の速度の有意な変化は認められず,腎機能/血圧の合併症や変化も認められませんでした.
結論
- 安定した腎臓移植受容者における特許AVFの選択的結合は,左心室筋質量の臨床的に有意な減少につながります.
- AVFの結合は腎機能や血圧に悪影響を及ぼさない安全な手順です.
- この研究は,腎臓移植患者の心血管改造を緩和するための治療戦略としてAVF結合の証拠を提供します.

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.
The renal cortex is the thick outer layer of the kidney. It...
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...
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...
Cardiac muscle, or myocardium, is a specialized type of muscle found exclusively in the heart. Its unique structural and functional characteristics enable the heart to perform its vital role of pumping blood throughout the body continuously and rhythmically. The cardiac muscle cells, or cardiomyocytes, possess an endomysium and perimysium but do not have an epimysium.
Compared to skeletal muscles, cardiac muscle cells are small and mostly have a single nucleus. Additionally, they are usually...
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...
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.
Fruits can be classified based on the number of flowers and the structure of the carpels involved in their...
