Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs) are regarded as nephrotoxins. Children commonly use NSAIDs and are susceptible to nephropathy, but the relationship between acute kidney injury (AKI) and use of NSAIDs is not well examined yet.
Objective: To evaluate the relationship between AKI and use of NSAIDs in hospitalized pediatric patients who are susceptible to nephropathy.
Methods: We conducted this systematic review and meta-analysis of observational studies by searching PubMed, Embase, and Cochrane Database for articles published up to June 1, 2020. Reports included involved children (age < 18 years) who used NSAIDs for various reasons and were admitted in the hospital. The main outcome measure was whether AKI occurred, and pooled odds ratio (OR) and 95% confidence intervals (CI) were calculated using generic inverse variance methods.
Results: Seven studies reporting risk of AKI in the hospitalized pediatric patients receiving NSAIDs were included applying a random-effects model. In the hospitalized pediatric population, the pooled OR of AKI for present NSAID exposure was 1.55 (95%CI 1.26-1.92).
Conclusions: NSAID exposure was associated with an approximate 1.6-fold rise in the odds of developing AKI in hospitalized pediatric patients. Avoidance, cautious use of NSAIDs and further evidence are needed. This study was registered with PROSPERO (identifier: CRD42021219779).
