Acute kidney injury in premature and low birth weight neonates: a systematic review and meta-analysis

Yang Wu et al. Pediatr Nephrol. 2022 Feb.

Abstract

Background: Acute kidney injury (AKI) is common and it is associated with poor clinical outcomes in premature and low birth weight neonates. This systematic review and meta-analysis was performed to summarize the literature and evaluate the prevalence, risk factors, and mortality of premature and low birth weight neonates with AKI.

Methods: A systematic search in PubMed, Embase, and the Cochrane Library was performed. Studies on the prevalence, risk factors, diagnosis, and outcomes of acute kidney injury in preterm neonates and neonates with low birth weight were included and analyzed.

Results: Fifty articles of 10,744 patients were included in this study. The overall rate of AKI from the pooled results of all patients was 25% (95% CI 20-30%) with heterogeneity among studies (I2 = 97%; P < 0.01). Patients with AKI had significantly higher rate of mortality than patients without AKI (odds ratio (OR) = 7.13; 95% CI 5.91-8.60; P < 0.01).

Conclusions: AKI was prevalent and was associated with high mortality rate among preterm and low birth weight neonates.

Keywords: Acute kidney injury; Low birth weight; Premature; Systematic review.
