Systemic and Histopathological Effects of Bromelain-Based Enzymatic Debridement in Human Burns—A Systematic Review

Background/Objectives: Bromelain-based enzymatic debridement (NexoBrid®) is an established tissue-preserving alternative to tangential excision in deep partial-thickness burns. Its clinical efficacy is supported by randomised trials, but its systemic effects are inconsistently described and its effects at tissue level in humans are largely unknown. The objective was to synthesise the human evidence on both domains and to determine, as a prespecified endpoint, whether any study has evaluated them in the same patients.

Methods

PubMed, Embase and Scopus were searched between 2016 and 2026 using two stream-specific strategies that shared their intervention and population blocks and differed only in their outcome block: Stream A, clinical outcomes reported with systemic biological parameters; Stream B, clinical outcomes reported with histopathological findings. Eligible studies were original human investigations published in the last ten years. Risk of bias was assessed with ROBINS-I and the JBI checklists, and the synthesis was narrative, following PRISMA 2020 and SWiM.
