摘要

Background

Prediabetes is associated with higher risk of chronic kidney disease (CKD), however studies investigating the prognostic index for incident CKD in patients with prediabetes are lacking. Thus, the present study aims to find the risk factors for CKD in prediabetic population.

Methods

We included 1220 prediabetic participants without CKD in the REACTION study and examined the associations of clinical indicators with CKD incidence with 3.6 years of follow-up using logistic regression analyses. To explore the nonlinear relationship between the Urine Albumin-To-Creatinine Ratio (UACR) and the hazard ratio (HR) of CKD, a Restricted Cubic Spline (RCS) analysis was conducted. Logistic regression analysis was employed to assess the association between UACR categories and the risk of CKD incidence.

Results

There were 78 (6.4%) individuals developed CKD, and elevated UACR was observed in patients who developed CKD. UACR was an independent risk factor of CKD after adjusting for covariates and RCS presented an association between elevated UACR and higher risk of CKD incidence. UACR cutoff points of 7.54 mg/g overall was associated with the risk of CKD progression. In comparison to a UACR range of 0-7.54 mg/g (B1), those who falling within the ranges of 7.54–14.95 (B2), 14.95–22.36 (B3), and 22.36-30 (B4), exhibited a significantly increased risk of CKD development. eGFR below the threshold of 81.64 mL/min/1.73m2 was significantly associated with an increased risk of CKD characterized by impaired glomerular filtration.

Conclusion

In conclusion, the novel UACR cutoff of 7.54 mg/g serves as an effective tool to identify individuals at high risk of developing CKD-ACR during the prediabetes stage.
