Gut Microbiota Influence Host Metabolism and Immune Responses in Atopic Dermatitis: A Next-Generation Sequencing-Based Functional Profiling Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Gut dysbiosis has been linked to immune imbalance in allergic diseases, but the underlying mechanisms remain unclear. We aimed to verify whether gut microbiota composition is associated with cellular, metabolic, and immune pathways in atopic dermatitis. Patients and Methods: Fifty adults with atopic dermatitis and 25 sex- and age-matched healthy controls were enrolled. Gut microbiome composition was assessed using V3-V4 16S rRNA sequencing. Functional pathways were inferred from microbiome data using PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States). Results: Despite only subtle differences in microbiota composition between patients with atopic dermatitis and controls, PICRUSt analysis identified significant differences in 149 functional pathways. Key pathways enriched in atopic dermatitis involved signal transduction mediated by protein kinases, as well as carbohydrate and lipid metabolism. Downregulated pathways included those related to energy metabolism, amino acid and nucleotide metabolism, antigen processing, and innate immune responses. In patients with atopic dermatitis, microbial diversity increased with EASI scores and IgE levels, correlating with additional predicted functional shifts. Conclusion: Our results suggest that even subtle structural differences in gut microbiota may exert significant functional effects in atopic dermatitis. Altered pathways could contribute to immune imbalance and impaired epidermal barrier function. These findings underscore the importance of incorporating functional analyses into future gut microbiota studies of atopic dermatitis to help identify therapeutic targets, including candidate probiotic strains for supplementation.
