まとめ
累積的な腎機能低下は,推定グルメラー濾過率 (eGFR) 負荷で測定され,頭蓋内動脈硬化症 (ICAS) のリスクを大幅に増加させます. この累積的な負荷は,単一の測定よりも,ICASをよく予測します.

- 流行病学について
背景:
- 頭蓋内動脈硬化症 (ICAS) は,脳卒中の主な原因である.
- 推定グルメルフィルタレーション率 (eGFR) とICASの間の長期的な関係は,まだ完全に理解されていません.
- 腎機能がICASの発達に及ぼす累積的な影響を調査することは,脳卒中予防戦略にとって極めて重要です.

- 累積的なeGFR負荷とeGFR傾きを5年間の連続測定を用いて計算する.
- ICAS事件を特定するために2021年12月までのフォローアップ (2016年-2021年)
主要な成果:
- 累積的なeGFRの負荷が高く,eGFRの傾きが高く,腎臓機能の低下が長く続くと,ICASのリスクが増加することが顕著でした.
- シングルタイムポイント eGFR < 90 mL/ min/ 1. 73 m2もICASとの有意な関連性を示した.

Glomerular 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 Drug Excretion: Glomerular Filtration
490
The kidney serves as the primary organ responsible for eliminating drugs and their metabolites from the body. This process, known as renal elimination, starts with glomerular filtration and results in urine formation. Each kidney houses millions of functional units called nephrons, where urine production occurs. A nephron has two main components: a renal corpuscle and a renal tubule.
Drugs gain access to the kidney via the renal artery, which progressively branches off into afferent arterioles....

Factors Affecting Renal Clearance: Renal Impairment

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...

Glaucoma: Overview
740
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Glomerular Filtration: Net Filtration Pressure
3.7K
Glomerular filtration, a key process in the kidneys, is regulated by three main pressures: Glomerular blood hydrostatic pressure (GBHP), Capsular hydrostatic pressure (CHP), and Blood colloid osmotic pressure (BCOP).
GBHP, with an average value of 55 mmHg, promotes filtration by pushing water and solutes through the filtration membrane. This is balanced by two opposing forces: CHP, a "back pressure" exerted against the filtration membrane by fluid already in the capsular space and renal...

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
