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.

This is a systematic review and meta-analysis of existing evidence regarding the possible effects of epothilones on spinal cord injury (SCI). This study aimed to investigate the possible effects of epothilone administration on locomotion recovery in animal models of SCI. Despite increasing rates of SCI and its burden on populations, no consensus has been reached about the possible treatment modality for SCI. Meanwhile, low-dose epothilones have been reported to have positive effects on SCI outcomes. Electronic databases of Web of Science, Scopus, Embase, and Medline were searched using keywords related to epothilones and SCI until the end of 2020. Two researchers screened the articles, and extracted data were analyzed using STATA ver. 14.0. Final results are reported as a standardized mean difference (SMD) with a 95% confidence interval (CI). After the screening, five studies were included in the analysis. Rats were used in all the studies. Two types of epothilones were used via intraperitoneal injection and were shown to have positive effects on the motor outcomes of samples with SCI (SMD, 0.87; 95% CI, 0.51 to 1.23; p=0.71). Although a slightly better effect was observed when using epothilone B, the difference was not significant (coefficient, −0.50; 95% CI, −1.52 to 0.52; p=0.246). The results of this study suggest that epothilones have positive effects on the improvement of motor function in rats, when administered intraperitoneally until a maximum of 1 day after SCI. However, current evidence regarding the matter is still scarce.
