Urine samples were obtained preoperatively and 4, 8, 12, 24, 48 and 72 h postoperatively, and urinary KIM-1 and NGAL contents were measured by enzyme linked immunosorbent assay and corrected against urine creatinine content. The receiver operating characteristic (ROC) curves click here were used to determine the area under the curve (AUCs) of urinary KIM-1 and NGAL for AKI. The baseline urinary KIM-1 contents were higher in AKI patients than non-AKI patients (P < 0.01). Urinary NGAL contents were also higher in AKI patients
than non-AKI patients (P < 0.001). The area under the curve (AUC) of urinary KIM-1 was 0.900 (P = 0.004) and at a cutoff of 338.26 pg/mg Cr, the sensitivity was 90% and the specificity was 75%. Adriamycin The AUC of urinary NGAL was 0.900 (P = 0.004) and at a cutoff of 261.76 ng/mg Cr, the sensitivity was 90% and the specificity was 87.5%. The combined AUC of urinary KIM-1 and NGAL was 0.938 (P = 0.002) with a sensitivity of 90% and a specificity of 100%. Cox regression analysis revealed that urinary KIM-1content 72 h after operation correlated with the prognosis of AKI patients (P = 0.009). When kidney viability was stratified by urinary KIM-1 content 72 h postoperatively, Kaplan–Meier analysis showed
that patients with a urinary content of KIM-1 < 138.20 pg/mg had a higher kidney viability rate than those with a urinary content of KIM-1 > 138.20 pg/mg. Urinary KIM-1 and NGAL had a good accuracy for detecting AKI. KIM-1 72 h postoperatively can predict the renal outcome of obstructive nephropathy. “
“Fibroblast growth factor 23 is reported Baf-A1 to be a pivotal regulator for the chronic kidney disease-mineral bone disorders, working in coordinated ways with phosphate, calcium, and parathyroid hormone. However, whether there is a relationship between fibroblast growth factor 23 and magnesium is currently unclear. To address this, we performed a cross-sectional observational study in haemodialysis patients. We measured the serum levels of fibroblast growth factor 23, magnesium and other factors that are implicated in chronic kidney disease-mineral
bone disorders in 225 haemodialysis patients. Simple correlation analysis showed that fibroblast growth factor 23 was not correlated with magnesium. However, upon multiple regression analysis, a significant negative correlation was found between fibroblast growth factor 23 and magunesium (b = −0.164, P = 0.0020). Moreover, the levels of fibroblast growth factor 23 in patients treated with magnesium oxide had significantly lower levels than those without magnesium oxide. We speculate that the magnesium is a potential regulator of fibroblast growth factor 23 levels in haemodialysis patients. Our data suggest that follow-up studies to elucidate the molecular mechanisms that underlie this relationship are warranted.
