Kidney Disease: Chronic Kidney Disease.

Area of Science:

• Nephrology
• Internal Medicine
• Public Health

Background:

• Chronic kidney disease (CKD) impacts 37 million US adults, involving complex renal damage processes.
• CKD is often asymptomatic, detected through urinalysis (proteinuria) or blood tests (elevated creatinine).
• Accurate estimation of glomerular filtration rate (GFR) is key for diagnosis and staging.

Purpose of the Study:

• To define CKD and its diagnostic criteria.
• To outline screening recommendations for high-risk populations.
• To emphasize management strategies for slowing CKD progression.

Main Methods:

• Utilizing the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation for GFR estimation.
• Considering Cystatin C levels for GFR estimation in specific patient groups.
• Classifying CKD based on GFR, proteinuria, and etiology.

Main Results:

• CKD is defined by GFR < 60 mL/min/1.73 m2 or persistent kidney damage evidence.
• Screening is advised for individuals with diabetes, hypertension, cardiovascular disease, or family history of kidney failure.
• Identifying and minimizing exposure to nephrotoxic drugs is essential.

Conclusions:

• CKD diagnosis relies on GFR thresholds and evidence of kidney damage.
• Proactive screening and risk factor management are vital for mitigating CKD.
• Optimizing underlying conditions like hypertension and diabetes is crucial for slowing disease progression.
