Summary
Estimating kidney function in older adults is challenging. New equations, particularly those using cystatin C, show promise for detecting chronic kidney disease (CKD) and improving geriatric outcomes, but require further validation.
Area of Science:
- Geriatrics
- Nephrology
- Biochemistry
Background:
- Aging is associated with structural and functional kidney changes.
- Chronic kidney disease (CKD) in older adults links to comorbidities, disability, and mortality.
- Current methods for estimating kidney function are difficult to apply in the elderly.
Purpose of the Study:
- To review age-related kidney changes and function estimation methods.
- To assess the impact of reduced kidney function on geriatric outcomes.
- To evaluate the reliability of equations for estimating glomerular filtration rate (eGFR) in older patients.
Main Methods:
- Literature review focusing on age-related kidney function.
- Analysis of existing equations for estimating glomerular filtration rate (eGFR).
- Evaluation of novel biomarkers and equations for kidney function assessment in geriatrics.
Main Results:
- Estimating kidney function in older adults presents unique challenges.
- Widely used eGFR equations based on serum creatinine have limitations in this population.
- Serum cystatin C-based equations show potential for improved accuracy in older individuals.
Conclusions:
- Accurate eGFR estimation is crucial for early CKD detection and management in the elderly.
- Existing creatinine-based equations are insufficient for older populations.
- Cystatin C-based equations warrant further investigation as a reliable method for assessing kidney function in geriatric patients.

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
354
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

371
In healthy individuals, serum creatinine levels remain stable due to a balance between its constant production—primarily from muscle metabolism—and renal excretion. Creatinine is freely filtered by the glomeruli, making it a valuable marker for estimating renal function. When the glomerular filtration rate (GFR) decreases, the kidneys can only eliminate less creatinine, causing serum levels to rise.Serum creatinine concentration is widely used to estimate creatinine clearance...

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...

2.1K
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.
