The association of plasma testosterone level and progression of diabetic nephropathy in male
摘要
Diabetic nephropathy (DN) is a leading cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD), significantly impacting the global burden of diabetes mellitus (DM). Testosterone has been implicated in the pathophysiology of DN, yet its specific role remains unclear.
MethodsThis retrospective cohort study analyzed 347 male patients with type 2 diabetes mellitus (T2DM), including 165 with DN and 182 without DN, to explore the relationship between plasma testosterone levels and DN progression. Clinical and biochemical data were collected, and univariate, multivariate regression, and logistic regression analyses were performed. A nomogram predictive model was developed incorporating DN risk factors.
ResultsNo significant difference in plasma testosterone levels was observed between DN and DM patients. However, testosterone levels varied significantly across DN stages, peaking in stage G5. Multivariate analysis identified testosterone (OR = 3.13, 95% CI [1.25–8.87]) as an independent risk predictor for poor DN prognosis. The predictive model combining Cyc, testosterone, Age, SBP, DBP, UACR, and demonstrated excellent prediction for the adverse outcomes in DN. (AUC = 0.923, 95% CI: 0.891–1).
ConclusionTestosterone plays critical roles in DN progression and prognosis. The developed nomogram offers a practical tool for risk stratification and management of male DN patients. Further research is needed to validate these findings and elucidate the mechanistic pathways linking testosterone to DN progression.
