The majority of “normal GFR” obese study participants who developed CKD, were initially found with increased concentrations of serum uric acid (5.9 ± 0.6 mg/dL; n = 14; 87.5%), cholesterol (194 ± 5.8 mg/dL; n = 15; 93.8%), and triglycerides (172 ± 4.9 mg/dL; n = 10; 62,5%) as well as urine NGAL concentration (9.8 ± 3.5 ng/ml; n = 13; 81,2%), as compared to “normal GFR” obese adolescents who did not develop CKD. This evidence concerns the gene LCN2 and chronic kidney disease.
