“…Urine albumin (albuminuria) and protein (proteinuria) losses in normal individuals are usually <30 mg/24 h, and lower than 150 mg/24 h, respectively. Since diagnosis, all patients had adhered to a renal diet that was low in sodium and/or phosphorus and/or protein, depending on the patients’ condition and CKD stage [ 4 , 20 , 21 ].…”

Background Ischemia-modified albumin (IMA) is a secreted biomarker for ischemic oxidative stress. This case-control study aimed to evaluate the association of ischemia-modified albumin (IMA) in saliva, serum, and urine with diagnosis of chronic kidney disease (CKD) in 24 children. Material/Methods The study involved 24 children with CKD. CKD was defined according to the Kidney Disease Improving Global Outcomes (KDIGO) diagnostic criteria. The control group consisted of 24 healthy children who were matched for age and gender to the experimental group. The concentration of IMA was determined by the colorimetric method in non-stimulated whole saliva (NWS), stimulated whole saliva (SWS), serum, and urine of children with CKD. The Mann-Whitney U test was used for inter-group comparisons. Results IMA levels were significantly higher in NWS ( P =0.0082) and SWS ( P =0.0014) of children with CKD than in the control group. The concentration of IMA in NWS was correlated with standard indicators of kidney function, including the estimated glomerular filtration rate (r=-0.798, P ≤0.0001), stage of CKD (r=0.814, P ≤0.0001), and serum creatinine (r=0.711, P ≤0.0001) and urea levels (r=0.738, P ≤0.0001). Conclusions Salivary IMA concentration depends on renal function in children. Salivary IMA discriminates children with end-stage kidney disease from children with mild and moderate CKD and healthy children with high sensitivity and specificity. Further research is required, including assessment of the diagnostic usefulness and validation of the biomarker in a clinical diagnostic study.
