[Can urine albumin/creatinine ratio replace 24 hours urinary albumin?]

Objective: To analyze the correlation between urinary albumin/creatinine ratio (ACR) and 24-hour urinary microalbumin (UMA) and evaluate the predictive value of ARC for early diabetic nephropathy. Methods: A total of 368 patients with type 2 diabetes mellitus were retrospectively collected. Early diabetic nephropathy was defined as 24h UMA 30~<300 mg/24h. The correlation between ACR and 24hUMA, and the area under the receiver operating characteristic (ROC) curve of ACR in diagnosis of early diabetic nephropathy were calculated. Gender, age, course of disease, fasting venous blood glucose, glycosylated hemoglobin, blood pressure, triglyceride and total cholesterol were used as adjusting variables to establish univariate and multivariate logistic models of ACR for early diabetic nephropathy, respectively. A regression model was used to evaluate the diagnostic value of ACR for early diabetic nephropathy. Results: The correlation between ACR and 24h UMA was 0.658. The area under ROC curve of ACR for early diabetic nephropathy was 0.907 before and 0.933 after adjustments of gender, age, course of disease, fasting venous blood glucose, glycosylated hemoglobin, blood pressure, triglyceride and total cholesterol, respectively. The OR value of ACR of diabetic nephropathy was 2.016 before and 2.762 after same adjustments. The calibration of Hosmer-Lemeshow chi-square test evaluation model was 19.362 before (P=0.13) and 14.928 after adjustments (P=0.061). Conclusion: ACR is a better predictor for early diabetic nephropathy although its value is influenced by gender, age, course of disease, blood sugar, lipid, and blood pressure.

Cytokine ratios in chronic periodontitis and type 2 diabetes mellitus

AIM

Chronic periodontitis may influence systemic cytokines in type 2 diabetes. This study aimed to evaluate the cytokine ratios in type 2 diabetes with, and without chronic periodontitis.

MATERIALS & METHODS

Gingival status, periodontal, glycemic parameters and serum cytokines were evaluated in participants grouped as healthy, chronic periodontitis, and type 2 diabetes with, and without chronic periodontitis.

RESULTS AND CONCLUSIONS

Cytokine ratios showed significant differences in type 2 diabetes and chronic periodontitis, were highest in participants having both type 2 diabetes and chronic periodontitis, with a statistically significant cut-off point and area under curve by receiver operating characteristic.
