“…Second, the study did not include information on the concomitant use of drugs, such as trimethoprim or cimetidine (43,44), which can inhibit the tubular secretion of creatinine, although the use of these medications is likely to be rare at the time period of CRIC enrollment. Our results are consistent with prior studies which have reported that CrCl is approximately 10%-30% higher than simultaneously measured GFR (16)(17)(18)(19)45). Third, since there was only one measurement of baseline iGFR and CrCl, we were not able to generate data on within-person CV from CRIC data and had to rely on data from previously published studies.…”

“…However, available empirical data supporting this notion primarily consist of studies showing that the CrCl/GFR ratio is higher in patients with lower measured GFR than in patients with higher measured GFR (Supplemental Table 1) (16)(17)(18)(19)(20).…”

“…To determine the individual prognosis of a patient with a renal disease, physicians currently make use of functional parameters such as serum creatinine, GFR, proteinuria, and the histologic information obtained from the renal biopsy. Several studies have shown that the current functional measurements are inaccurate as measures of progression in chronic renal failure (1,2). An extensive number of studies have shown that certain histologic changes in the biopsy are associated with an adverse outcome.…”

“…This hyperbolic relationship implies that at a GFR close to normal, large changes in GFR correspond with only small changes in cystatin C. Therefore, mild elevation of serum cystatin C as typically seen in renal transplant recipients, may already reflect marked impairment of renal function, leading to overestimation of GFR. Using creatinine clearance as reference method to assess the performance of serum cystatin C and serum creatinine, we are aware that creatinine clearance can result in an inaccurate estimate of GFR [2,22,261. However, good agreement between creatinine clearance and "true" markers of GFR as inulin [3], 1251-iothalamate [16] and 99mTc-DTPA clearance [17,20] at all levels of renal function was reported.…”
