OBJECTIVE: Albumin creatinine ratio (ACR) in a spot urine is replacing albumin excretion rate (AER) in 24 hour-collected urine as screening test for microalbuminuria because of simplicity and reliance. There are some controversies about the most relevant ACR value in detecting microalbuminuria. Most commonly recommended cut-off value is 30 mg/gm. Some recommends sex-specific ACR cut-off value: 17 mg/gm for men, 25 mg/gm for women. In this report, we evaluated diagnostic characteristics of ACR according to above different cut-off values and estimated most relevant ACR cut-off value for microalbuminuria in patients with type 2 diabetes. METHODS: Urine was collected for 24hours for the measurement of microalbumin in type 2 diabetes who admitted in SNUH. The next day, first morning urine was obtained for microalbumin and creatinine concentration in patients with albumin excretion rate (AER) below 300 mg/day. RESULTS: 33% of total 156 patients had microalbuminuria. ACR correlated positively with AER. According to regression equations of AER and ACR, an AER of 30 mg/day corresponded to an ACR of 32 mg/gm. Positive and negative predictive values of ACR 30 mg/gm for microalbuminuria were 81% and 84% in men. In women, these were 80% and 86% respectively. Using recommended sex-specific ACR cutoff values, these were 52% and 94% in men, 68% and 91% in women. The most relevant ACR cutoff from receiver operating characteristics curve was 32 mg/gm in our study. CONCLUSION: Using ACR 30 mg/gm as cut-off values of microalbuminuria, positive and negative predictive value were above 80% in both men and women. In patients visiting SNUH, ACR 32 mg/gm may be more relevant in screening microalbuminuria in type 2 diabetes.

Proteinuria, including albuminuria, is a primary or major clinical sign of kidney disease. The urine albumin-to-creatinine ratio (UACR) and urine protein-to-creatinine ratio (UPCR) are used to screen patients with chronic diseases, such as diabetes and hypertension, which increase the risk of chronic kidney disease. Here, we evaluated the performance of the MEDITAPE UC-11A strips (Sysmex, Japan), compared with that of the quantitative assay, in assessing UACR and UPCR.METHODS: We obtained a total of 808 random urine specimens. UACR and UPCR, semiquantitatively analyzed using MEDITAPE UC-11A strips with a UC-3500 automated strip reader (Sysmex, Japan), were compared to UACR and UPCR measured by a quantitative assay.RESULTS: The concordance rates of UACR and UPCR, analyzed using MEDITAPE UC-11A, and those analyzed using the quantitative assay, were 70.1% and 78.7%, respectively. Using UACR, analyzed via quantitative assay, as a reference to estimate albuminuria (UACR >30 mg/g), the concordance rate, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of UACR, analyzed using MEDITAPE UC-11A, were 80.5, 97.5, 67.0, 70.3, and 97.1%, respectively. Using UPCR, analyzed via quantitative assay, as a reference to estimate proteinuria (UPCR >0.15 g/g), the concordance rate, sensitivity, specificity, PPV, and NPV of UPCR, analyzed using MEDITAPE UC-11A, were 86.7, 94.4, 81.5, 77.6, and 95.6%, respectively.CONCLUSIONS: UACR and UPCR, analyzed using MEDITAPE UC-11A, exhibited relatively high sensitivity and NPV, which is beneficial for laboratory screening for both albuminuria and proteinuria.]]>

Diabetes mellitus (DM) has grown up to be an important issue of global public health because of its high incidence rate. Diabetic kidney disease (DKD) is the main cause of end-stage kidney disease (ESKD). Therefore, early diagnosis and timely prevention and treatment of DKD are essential for the progress of DM. The clinical diagnosis and staging of DKD are mostly based on the urinary albumin excretion rate (UAER) and estimated glomerular filtration rate (eGFR). However, clinically, DKD patients show normoalbuminuric diabetic kidney disease (NADKD) instead of clinical proteinuria. The old NADKD concept is no longer suitable and should be updated accordingly with the redefinition of normal proteinuria by NKF/FDA (National Kidney Foundation/Food and Drug Administration). Based on the relevant guidelines of DM and chronic kidney disease (CKD) and combined with the current situation of clinical research, the review described NADKD from the aspects of epidemiology, pathological mechanism, disease diagnosis, clinical characteristics and biomarkers, to arouse the new understanding of NADKD in the medical profession and pay attention to it.
