Ha Bansal, MD, MAS1 1University of California, San FranciscoAbstractBackground–Urine albumin-creatinine ratio (ACR) and protein-creatinine ratio (PCR) are important markers of kidney damage and are utilized for prognosis in persons with chronic kidney disease (CKD). In spite of how usually these measurements are completed in clinical practice, somewhat few studies have directly compared the efficiency of those two measures with regard to associations with clinical outcomes, which may well inform clinicians about which measure of urinary protein excretion is finest. We studied the association of ACR and PCR with popular complications of CKD. Study Design–Cross-sectional study. Setting Participants–3,481 participants with CKD Mps1 Biological Activity within the Chronic Renal Insufficiency Cohort (CRIC) study. Predictors–ACR and PCR. Outcomes–We examined the association among ACR and PCR with measures of widespread CKD complications: serum hemoglobin, bicarbonate, parathyroid hormone, phosphorus, potassium and albumin. Measurements–Restricted cubic spline analyses adjusted for estimated glomerular filtration rate (eGFR; calculated by the MDRD [Modification of Diet program in Renal Disease] Study Equation) had been performed to study the continuous association with our predictors with each and every outcome. Results–Mean eGFR was 43 ?13 (SD) ml/min/1.73 m2 and median levels of PCR and ACR have been 140 and 46 mg/g, respectively. In continuous analyses adjusted for eGFR, larger ACR and PCR have been comparable and both had been related with lower levels of serum hemoglobin, bicarbonate, and albumin and larger levels of parathyroid hormone, phosphorus, and potassium. Across all outcomes, the associations of ACR and PCR have been comparable with only small, absolute?2013 The National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

Equivalent associations have been seen in patients with diabetes mellitus. Limitations–Participants largely had moderate CKD with low levels of ACR and PCR, so outcomes might not be generalizable to all CKD populations. Conclusions–In persons with CKD, ACR and PCR are reasonably comparable in their associations with typical complications of CKD. Therefore routine measurement of PCR may perhaps provide comparable data as ACR in managing instant complications of CKD. Chronic kidney illness (CKD) is quite prevalent am.
