Update on cystatin C: incorporation into clinical practice

Area of Science:

• Nephrology
• Clinical Chemistry
• Biomarker Research

Background:

• Creatinine-based glomerular filtration rate (GFR) estimation is standard for monitoring kidney function.
• Emerging evidence suggests cystatin C improves GFR classification for chronic kidney disease (CKD).
• Cystatin C aids in understanding CKD complications.

Purpose of the Study:

• To review and update the literature on cystatin C.
• To critically evaluate recent high-impact studies on cystatin C.
• To provide a practical guide for clinicians incorporating cystatin C into practice.

Main Methods:

• Literature review and synthesis of existing studies.
• Critical evaluation of recent high-impact research.
• Analysis of cystatin C's role in current kidney disease guidelines.

Main Results:

• Cystatin C demonstrates potential for enhanced GFR estimation compared to creatinine.
• Evidence supports cystatin C's utility in specific clinical populations for CKD classification.
• Cystatin C aids in predicting and understanding CKD-related complications.

Conclusions:

• Cystatin C is a valuable biomarker for kidney function assessment.
• Integrating cystatin C into clinical practice can improve CKD management.
• Further research and clinical adoption of cystatin C are warranted.
