Systematic review and meta-analysis links prenatal NSAIDs to higher kidney disease risk in children
This systematic review and meta-analysis examined the relationship between prenatal NSAIDs exposure and kidney disease risk in children. The analysis included a sample size of 4,159,617 individuals. The primary outcome assessed was kidney disease risk. The study did not report adverse events or serious adverse events. The authors did not report tolerability or discontinuations. The review did not report a specific setting or follow-up duration.
Key findings indicate an adjusted odds ratio of 2.40 (95% CI 1.84–3.13) for kidney disease risk associated with prenatal NSAIDs use. Unadjusted analysis showed an odds ratio of 1.10 (95% CI 1.05–1.15). Overall risk yielded an odds ratio of 1.36 (95% CI 1.14–1.62). Risk was also increased in the second trimester with an odds ratio of 1.17 (95% CI 1.09–1.26) and in the third trimester with an odds ratio of 1.10 (95% CI 1.09–1.11).
The authors acknowledge that the data do not solve causality issues concerning potential confounding by other risk factors. They state that more high-quality studies are needed to establish whether the association with NSAIDs is causal. The review did not report practice relevance or funding conflicts. Clinicians should interpret these findings cautiously given the limitations regarding confounding.
