Correlation of dehydroepiandrosterone with diabetic nephropathy and its clinical value in early detection.

ABSTRACT:

Aims/introduction

This study was carried out to assess the association of dehydroepiandrosterone (DHEA) with diabetic nephropathy (DN) in patients with type 2 diabetes mellitus to better predict the progression of diabetic nephropathy.

Materials and methods

A total of 1,082 patients with type 2 diabetes mellitus in the Department of Endocrinology and Metabolism of Tianjin Medical University General Hospital were enrolled in this study, and grouped for comparison. The effect of serum DHEA on DN was evaluated by multivariate logistic regression analysis, and receiver operating characteristic curves were established to explore the optimal concentration of DHEA in patients with DN and non-DN.

Results

DHEA was significantly decreased in patients with DN (P < 0.001). The prevalence of DN was significantly higher in the low DHEA quartile than in the other quartiles (P < 0.001). Spearman-related analysis showed that DHEA levels were negatively correlated with patient age, course of diabetes, systolic blood pressure, blood creatinine, uric acid, urine albumin-to-creatinine ratio, 24-h urine microalbumin, 24-h urine protein quantification and glomerular filtration rate, and positively correlated with body mass index, total cholesterol and low density lipoprotein. Logistic regression analysis showed that the effect of DHEA on DN was statistically significant (P < 0.001). The receiver operating characteristic curve showed that the sensitivity was 81.4%, the specificity was 70% and the area under the curve was 0.812 when the optimal cut-off value was 1,640 (pg/mL).

Conclusion

DHEA is significantly associated with DN and might be a protective factor for DN, and is important for the prediction of DN.
