Objective To investigate the values of urine neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecular-1 (KIM-1) and interleukin-18 (IL-18) in the diagnosis of acute kidney injury (AKI) in children after cardiopulmonary by-pass (CPB). Methods Sixty-seven patients who had undergone CPB were recruited from March to June 2013 and assigned to acute kidney injury group (AKI group) or non-acute kidney injury group (non-AKI group) according to the pediatric RIFLE (pRIFLE) cri-teria. Serum and urine samples were collected from each patient at 30 min, 2 h, 4 h, 24 h, 48 h and 72 h after CPB for serum and urine creatinine, urine NGAL, KIM-1 and IL-18. All the data were evaluated by receiver operator characteristic curve (ROC) analysis and area under curve (AUC) analysis. Results Twenty-three cases (34.3%) had AKI in 67 children after CPB. Among them 15 cases were risk-stage AKI, 4 cases injury-stage AKI, 3 cases failure-stage AKI and 1 cases loss-stage AKI. The levels of urine NGAL/Ucr were higher in AKI group than those in non-AKI group at 4h, 48h and 72h after CPB (P<0.05). The cut-off value of NGAL/Ucr was 1.200 at 4 h after CPB, the sensitivity and specificity for prediction of AKI were 0.864 and 0.561, and the AUC was 0.671 (95%CI:0.537-0.804). The levels of urine KIM-1/Ucr were higher in AKI group than those in non-AKI group at 48h and 72 h after CPB (P<0.05). The cut-off value of KIM-1/Ucr was 1.162 at 24h after CPB, the sensitivity and specificity for prediction of AKI were 0.773 and 0.512, and the AUC was 0.698 (95%CI:0.563-0.834). The levels of IL-18/Ucr were higher in AKI group than those in non-AKI group at 4 h after CPB (P<0.05). The cut-off value of IL-18/Ucr was 0.04 at 4 h after CPB, the sensitivity and specificity for predici-ton of AKI were 0.773 and 0.561, and the AUC was 0.655 (95%CI:0.510-0.800). Conclusions It is indicated that urine NGAL, KIM-1 and IL-18 may have important clinical values for early prediction of AKI.

OBJECTIVETo investigate the new biomarkers of acute kidney injury, as well as to confirm the values of response gene to complement 32 (RGC-32) for early diagnosis of acute kidney injury by comparing the values of serum creatinine (Scr) and cystatin C (CysC) in children who had undergone cardiopulmonary bypass (CPB).

METHODSixty-seven patients who had accepted CPB were recruited from the cardiac surgery intensive care unit, Children's Hospital Affiliated to Shanghai Jiao Tong University from March to June 2013 and assigned to acute kidney injury group (group AKI) or non-acute kidney injury group (group non-AKI), on the basis of the definition by the pediatric RIFLE (pRIFLE) criteria. Also 30 healthy control children were recruited. Serum samples were taken regularly from each patient after CPB at 30 min, 2 h, 4 h, 24 h, 48 h and 72 h for RGC-32. Serum samples were tested by enzyme linked immunosorbent assay (ELISA) which was employed to determine the levels of serum RGC-32. Scr and CysC were analyzed by HITACHI 7180 automatic biochemical analyzer. All the data were analyzed by receiver operator characteristic curve (ROC) and area under curve (AUC).

RESULTThe incidence of AKI was 34% (23/67), including 15 cases with risk stage AKI, 4 cases with injury stage AKI, 3 cases with failure stage AKI, 1 cases with loss stage AKI. Three out of four subjects with Failure stage AKI and the one case with Loss stage all accepted renal replacement therapy. CPB group had a higher level of serum RGC-32 than that of pre-operation after CPB 30 minute [(2.88 ± 0.68) µg/L vs. (1.39 ± 0.31) µg/L, P < 0.05]. At the same time, comparing with the non-AKI group, the levels of serum RGC-32 were higher than that of controls 30 min, 2 h, 4 h, 24 h and 48 h after CPB (t = 2.560, 2.180, 2.818, 2.226, 3.017; P < 0.05). The values for the AUC were determined for RGC-32 as 0.770, 0.707, 0.768, 0.728,0.723 and 0.770 after CPB 30 min, 2 h, 4 h, 24 h, 48 h and 72 h. The values for sensitivity of serum RGC-32 30 min, 2 h and 4 h after CPB was 0.914, 0.824, 0.824 and the values for specificity of serum RGC-32 was 0.619, 0.667, 0.810, respectively. But the values for sensitivity of CysC was 0.625, 0.813, 0.813, and specificity 0.571, 0.619, 0.571, respectively. The values for sensitivity of Scr was 0.625, 0.625, 0.813 and specificity was 0.571, 0.571, 0.524, respectively.

CONCLUSIONThe sensitivity of serum RGC-32 for detecting AKI was much higher than that of Scr and serum CysC in children who had accepted CPB, and that RGC-32 may be a new biomarker for early detection of AKI. However, the conclusion needs to be further elucidated.

Autism spectrum disorder (ASD) is one of the common neurodevelopmental disorders in children. Its etiology and pathogenesis are poorly understood. Previous studies have suggested potential changes in the complement and coagulation pathways in individuals with ASD. In this study, using multiple reactions monitoring proteomic technology, 16 of the 33 proteins involved in this pathway were identified as differentially-expressed proteins in plasma between children with ASD and controls. Among them, CFHR3, C4BPB, C4BPA, CFH, C9, SERPIND1, C8A, F9, and F11 were found to be altered in the plasma of children with ASD for the first time. SERPIND1 expression was positively correlated with the CARS score. Using the machine learning method, we obtained a panel composed of 12 differentially-expressed proteins with diagnostic potential for ASD. We also reviewed the proteins changed in this pathway in the brain and blood of patients with ASD. The complement and coagulation pathways may be activated in the peripheral blood of children with ASD and play a key role in the pathogenesis of ASD.
