Insights

Serum creatinine levels are linked to cardiovascular disease (CVD) risk factors. These associations are stronger in older adults, with lifestyle factors being more influential in middle-aged individuals.

Area of Science:

  • Nephrology
  • Cardiology
  • Public Health

Background:

  • Serum creatinine is a recognized cardiovascular disease (CVD) risk factor and a measure of glomerular filtration rate.
  • Understanding serum creatinine determinants in the general population is crucial for public health.

Purpose of the Study:

  • To investigate the determinants of serum creatinine in a large, diverse general population sample.
  • To explore age- and sex-specific associations between serum creatinine and various health and lifestyle factors.

Main Methods:

  • The Hordaland Health Study included over 18,000 participants across different age groups (41-49 and 71-74 years) and sexes.
  • Data collection involved questionnaires on lifestyle and medical history, physical examinations, and non-fasting blood samples.
  • Multiple linear and logistic regression analyses were employed to identify determinants of serum creatinine.

Main Results:

  • Male and older participants exhibited higher serum creatinine levels.
  • In older adults, creatinine correlated with triglycerides, CVD, upper-arm circumference, and antihypertensive use, and inversely with smoking.
  • In middle-aged individuals, creatinine was associated with upper-arm circumference, lipids, exercise, and inversely with smoking and alcohol intake.

Conclusions:

  • High serum creatinine is associated with CVD risk factors in the general population.
  • These associations are more pronounced in older individuals.
  • Lifestyle variables play a relatively greater role in determining serum creatinine in middle-aged subjects.

Drug Dosing in Renal Diseases: Measurement of Serum Creatinine Concentration and Clearance

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 (Clcr), a...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

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. This equation is...

Serum Studies: Renal Function Tests

Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
Factors Affecting Renal Clearance: Renal Impairment01:17

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...

Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate

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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

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...
