ABSTRACT
BACKGROUND:
The relationship between circulating bile acids (BAs) and kidney function among patients with type 2 diabetes is unclear. We aimed to investigate the associations of circulating concentrations of BAs, particularly individual BA subtypes, with chronic kidney disease (CKD) in patients of newly diagnosed type 2 diabetes.METHODS:
In this cross-sectional study, we included 1234 newly diagnosed type 2 diabetes who participated in an ongoing prospective study, the Dongfeng-Tongji cohort. Circulating primary and secondary unconjugated BAs and their taurine- or glycine-conjugates were measured using ultraperformance liquid chromatography-tandem mass spectrometry. CKD was defined as eGFR < 60 ml/min per 1.73 m2. Logistic regression model was used to compute odds ratio (OR) and 95% confidence interval (CI).RESULTS:
After adjusting for multiple testing, higher levels of total primary BAs (OR per standard deviation [SD] increment 0.78; 95% CI 0.65-0.92), cholate (OR per SD 0.78; 95% CI 0.66-0.92), chenodeoxycholate (OR per SD 0.81; 95% CI 0.69-0.96), glycocholate (OR per SD 0.81; 95% CI 0.68-0.96), and glycochenodeoxycholate (OR per SD 0.82; 95% CI 0.69-0.97) were associated with a lower likelihood of having CKD in patients with newly diagnosed type 2 diabetes. No significant relationships between secondary BAs and odds of CKD were observed.CONCLUSIONS:
Our findings showed that higher concentrations of circulating unconjugated primary BAs and their glycine-conjugates, but not taurine-conjugates or secondary BAs, were associated with lower odds of having CKD in patients with type 2 diabetes.Key words
