Results

CKD is a comorbidity that occurs frequently in COPD patients, and we believe that renal function in COPD patients should preferably be evaluated based not only on Cr but also in combination with Cys.

The Cys level was significantly higher and eGFRCys was significantly lower in the COPD group . While the prevalence of CKD evaluated based on eGFRCr was 31% in the COPD group and 8% in the non-COPD group , the evaluated prevalence based on eGFRCys was 53% in the COPD group and 15% in the non-COPD group , demonstrating an even higher prevalence.
