Assessing the value of serum and urinary interleukins for diagnosis of acute kidney injury in children and adolescents: A systematic review and meta-analysis.

ABSTRACT:

Introduction

Several studies have questioned the diagnostic utility of interleukins (IL) in detecting acute kidney injury (AKI) in pediatric population. Therefore, the present systematic review and meta-analysis aims to assess the diagnostic value of ILs in pediatric AKI patients.

Method

Two independent researchers screened records acquired through searching in Medline, Embase, Scopus, and Web of Science, until the end of 2020. Articles evaluating serum and urinary levels of ILs in AKI patients were included in this study. Data were extracted and analyzed using STATA software.

Results

Twenty-one studies were included. Analyses showed that AUC, sensitivity, specificity and diagnostic odds ratio of urinary IL-18 for diagnosing AKI were 0.77 (95% CI: 0.74, 0.81), 0.64 (95% CI: 0.32, 0.87), 0.75 (95% CI: 0.62, 0.85) and 6 (95% CI: 1, 23), respectively. Those values were 0.79 (95% CI: 0.75, 0.83), 0.58 (95% CI: 0.37, 0.76), 0.87 (95% CI: 0.66, 0.96), and 9 (95% CI: 4, 20) for serum IL-6, and 0.72 (95% CI: 0.68, 0.76), 0.53 (95% CI: 0.34, 0.72), 0.79 (95% CI: 0.60, 0.91) and 4 (95% CI: 2, 8) for serum IL-8, respectively. Urinary levels of ILs 6, 8 and 10 were not significantly different between AKI patients and the non-AKI control group. Serum levels of ILs 10 and 18 were not adequately evaluated in the studies.

Conclusion

IL-18 urinary levels and IL-6 and IL-8 serum levels are significantly higher in AKI patients compared to the non-AKI group. However, their low sensitivity and specificity in detecting AKI questions their diagnostic value.

Project description:Acute kidney injury (AKI) is a major contributor to in-hospital morbidity and mortality. Vancomycin, one of the most commonly used antibiotics in a clinical setting, is associated with AKI, with its incidence ranging up to 43%. Despite the high demand, few studies have investigated serum biomarkers to detect vancomycin-induced kidney injury (VIKI). Here, we evaluated the diagnostic value of nine candidate serum biomarkers for VIKI. A total of 23,182 cases referred for vancomycin concentration measurement from January 2018 to December 2019 were screened and 28 subjects with confirmed VIKI were enrolled (VIKI group). Age- and sex- matched control group consisted of 21 subjects who underwent vancomycin therapy without developing VIKI (non-VIKI group), and 23 healthy controls (HC group). The serum concentrations of clusterin, retinol binding protein 4 (RBP4), interleukin-18 (IL-18), tumor necrosis factor receptor 1 (TNF-R1), C-X-C motif chemokine ligand 10 (CXCL10), neutrophil gelatinase-associated lipocalin (NGAL), osteopontin, trefoil factor-3 (TFF3), and cystatin C were compared among the three groups, and their correlations with estimated glomerular filtration rate (eGFR) and diagnostic values for VIKI were assessed. All of the biomarkers except clusterin and RBP4 exhibited significant elevation in the VIKI group. Serum TFF3, cystatin C, TNF-R1, and osteopontin demonstrated an excellent diagnostic value for VIKI (TFF3, area under the curve (AUC) 0.932; cystatin C, AUC 0.917; TNF-R1, AUC 0.866; osteopontin, AUC 0.787); and except osteopontin, a strong negative correlation with eGFR (TFF3, r = -0.71; cystatin C, r = -0.70; TNF-R1, r = -0.60). IL-18, CXCL10, and NGAL showed weak correlation with eGFR and moderate diagnostic value for VIKI. This study tested multiple serum biomarkers for VIKI and showed that serum TFF3, cystatin C, TNF-R1, and osteopontin could efficiently discriminate VIKI patients. Further studies are warranted to clarify the diagnostic value of these biomarkers in VIKI.
