en Usefulness of A Random Spot Urine Proteins-to-Creatinine Ratio to Screen for Increased Albuminuria in Patients with Type 1 Diabetes بیوشیمی Biochemistry مقالات اصلی Original Article <div style="text-align: justify;">Background: Moderately increased albuminuria is a biomarker for early onset diabetic nephropathy. The aim of this study was to evaluate the performance of use proteinuria-to-creatininuria ratio (UPCR) at different cut-off to screen for increased albuminuria using albuminuria-to-creatininuria ratio (UACR) as a gold standard.  Methods: This was a cross-sectional study. A random spot urine sample was collected from patients with type 1 diabetes to measure albuminuria and total proteinuria using respectively an immunoturbidimetric and a colorimetric assay. Albuminuria was expressed as UACR and proteinuria as UPCR. The area under the curve (AUC) method and the kappa coefficient were used to compare UPCR and UACR. Results: In 150 diabetic patients, moderately increased albuminuria was detected in 33.3% using UACR and 35.3% using UPCR at 272 mg/g. UPCR thresholds of 130, 150, 180 and 200 mg/g yielded higher detection rates than UACR. However, all UPCR cut-offs showed low diagnostic accuracy (AUC < 70%), and agreement with UACR was mild (kappa < 0.40). Conclusion: The level of agreement between UPCR and UACR was moderate. It is not sufficient for UPCR to replace UACR to screen for increased albuminuria in patient with type 1 diabetes.</div> Albuminuria, Diabetes, Diabetic Nephropathyn, Kidney Diseases, Proteinuria. 561 569 http://rbmb.net/browse.php?a_code=A-10-1614-1&slc_lang=en&sid=1 El Hadji Malick Ndour elhadjimalick1.ndour@ucad.edu.sn. 100319475328460021585 100319475328460021585 Yes Department of Pharmaceutical Biochemistry, Faculty of Medicine, Pharmacy and Dentistry, Cheikh Anta Diop University, Dakar, Senegal.
