Abstract:

Objective

To investigate the predictive value of urinary TIMP-2×IGFBP7 for sepsis acute kidney injury (AKI) by the Meta-analysis.

Methods

The database of PubMed, Web of Science, Cochrane, Embase, CNKI, WanFang, VIP and CBM were searched. Data was analyzed by RevMan 5.3 and Meta-Disc 1.4.

Results

Six studies involving 592 patients were included. Among them, 2 studies were from Western countries, while 4 studies were from China. Pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio with corresponding 95% confidence interval were 0.82 (0.76-0.87), 0.59 (0.54-0.64), 3.11 (1.47-6.56), 0.27 (0.13-0.57) and 12.92 (4.23-39.41), respectively. The area under the curve for summary receiver operating characteristic curves was 0.8497 with a Q* value of 0.7809. Subgroup analysis showed that the predictive accuracy of TIMP-2×IGFBP7 was higher in stage 1 AKI and Chinese population, with AUCs of 0.9072 and 0.8920, respectively.

Conclusion

Urinary TIMP-2×IGFBP7 is an early predictive marker for sepsis AKI, especially in stage 1 AKI and Chinese population.
