Association Between Renal Reserve Function and Progression of Renal Function to Predict CKD Risk in Thai Elderly

• Conditions: Elder; Renal Function Abnormal

• Registration Number: NCT05158959
• Lead Sponsor: Chulalongkorn University

Brief Summary

This study investigates renal functional reserve in elderly.

Detailed Description

The prevalence of CKD in elder is high as age has been a variable in eGFR equation. eGFR by calculation always declines in parallel with age. The assumption that a persistent over 3 months of eGFR less than 60 mL/min/1.73m2 define CKD with risk of progression and need refer to nephrologist may not necessary true in aging population. We study renal functional reserve in elderly population who risk of CKD progression and ESRD is the highest prevalence in human life cycle and explore whether renal functional reserve can be used as ad additional marker of CKD progression in elderly.
