- ハイパーカリミアおよび関連する代謝性酸性症候群に寄与する要因を特定する.
主な方法:
- シクロスポリン受給者における血清カリウム濃度を,プレドニゾロンおよびアザチオプリン受給者と比較した.
- 腎機能,酸塩状態,および高カリミア患者におけるホルモンレベル (アルドステロン,レニン) を分析した.
- 尿のpH値とベータブロッカーの影響と腎切除の評価.
主要な成果:
- サイクロスポリン群で9ヶ月間観察された平均血清カリウム濃度が著しく高かった.
- シクロスポリン投与を受けた43人の患者のうち7人が持続性高カリミア (6.0-7.1 mmol/l) と高塩素性酸化症を発症した.
- 低アルドステロン症,腎管不全,および低白血症 (ベータブロッカーによる可能性がある) は,高カリミア患者で関与していました.
結論:
- 腎臓移植患者におけるサイクロスポリン誘発の高カリミアは,カリウムと水素イオン分泌の低下と関連しています.
- ベータブロッカーによって悪化する可能性のあるヒポレニニネミアとヒポアルドステロン症候群は,この状態に寄与します.

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...
Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...
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...
Acute Kidney Injury IV: Diagnostic Studies and Prevention
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
