まとめ
COVID-19感染は長期にわたる腎不全を引き起こし,感染後18ヶ月間持続する推定グルメルフィルタレーション率 (eGFR) が低下する. 高齢と心血管疾患は 腎臓機能不全のリスクを高めます
科学分野:
- 腎臓科
- 感染症
- 公衆衛生
背景:
- 腎機能不全は,急性COVID-19における一般的な合併症です.
- この腎機能障害の長期的持続は,ほとんど特徴づけられていない.
- COVID-19後の腎臓の副作用を理解することは,患者の管理に極めて重要です.
研究 の 目的:
- 急性COVID-19および感染後3-6ヵ月および12-18ヵ月で推定された球過濾率 (eGFR) によって測定された腎臓機能を比較する.
- COVID-19後の状態の個体における患者特徴とeGFRの関係を調査する.
- COVID-19後の患者と対照群のEGFRの違いを評価する.
主な方法:
- COVID-19後の95人の患者と94人の対照群を含むコホート研究.
- 感染後3~6ヶ月と12~18ヶ月で生物学的サンプルを採取し,急性感染のデータは医療記録から得られた.
- 混合効果と線形回帰モデルを使用して,eGFRおよび関連因子を分析した.
主要な成果:
- 61例の完全症例のうち,感染中にEGFR < 90mL/ min/ 1. 73m2は50. 8%で,対照群の40. 4%と比較して3~6ヶ月で68. 9%,12~18ヶ月で75. 4%に上昇した.
- eGFRの低下は,高齢化,入院,既にある心血管疾患/高血圧と関連していた.
- 混同因子を調整した後に,eGFRはCOVID-19後の患者で12〜18ヶ月で有意に低下した.
結論:
- 過去のCOVID-19感染は,eGFRを最大18ヶ月まで減少させる.
- 高齢や心血管疾患/高血圧などの併発性疾患などの要因は,COVID-19後の腎臓への影響を悪化させる.
- これらの発見は,COVID-19感染後の慢性的な腎機能低下の可能性を強調しています.

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

01:28Glomerular Filtration Rate and its Regulation
3.3K
The Glomerular Filtration Rate (GFR) is a measure of kidney function, reflecting the volume of filtrate formed per minute in the kidneys. On average, GFR is approximately 125 mL/min in males and 105 mL/min in females. Maintaining a relatively constant GFR is essential for the kidneys to effectively regulate body fluid homeostasis and maintain extracellular stability.
GFR regulation involves two primary intrinsic controls: the myogenic and tubuloglomerular feedback mechanisms.

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

01:23Renal Clearance
1.3K
The glomerular filtration rate (GFR) is a critical marker of kidney function, reflecting the efficiency of filtration by the glomeruli. Renal clearance of specific substances, such as inulin or creatinine, is commonly used to measure GFR.
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

01:22Acute Kidney Injury I: Introduction
72
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
