Borderline
Quantitative synthesis revealed a significant and consistent systemic depletion of circulating acetate and propionate in adult CKD patients compared to healthy controls (p < 0.05).
CKD is associated with a profound systemic reduction in acetate and propionate, supporting the model of a compromised gut-kidney axis based on converging evidence.
The divergent results for butyrate in paediatric versus adult populations suggest that SCFA metabolism is influenced by age-related factors or compensatory mechanisms.

Einfach gesagt: Allergy published by European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.
Sasaki M et al. · Allergy (2024)
Overall, there was some evidence showing that the three main SCFAs (acetate, propionate and butyrate) in the first few years of life had a protective effect against allergic diseases, especially for atopic dermatitis, wheeze or asthma and IgE-mediated food allergy in childhood.
The association between each SCFA and allergic disease appeared to be different by disease and the age of assessment.

Oh KK et al. · Cells (2022)
Then, we implemented protein-protein interaction (PPI) networks with 342 overlapping target, another subnetwork was constructed with the top 30% degree centrality (DC), and the final core networks were obtained after screening the top 30% betweenness centrality (BC).
The final core targets were IL6, AKT1, and ALB.
We showed that the three core targets interacted with three other components via the MSMT network in alleviating obesity, i.e., four microbiota, two substrates, and six metabolites.

Results Probiotic supplementation, especially multispecies formulations, initiated in the first trimester led to a mean reduction in gestational weight gain (GWG) of 1.25 kg (95% CI: -1.78 to -0.72 kg; p < 0.001) compared to controls.
Furthermore, postpartum weight retention was reduced by an average of 1.05 kg (95% CI: -1.53 to -0.58 kg; p < 0.001) when probiotic use extended into the postpartum period.
The heterogeneity in strains, dosage, and duration and pooled analysis consistently favored probiotic intervention.

Einfach gesagt: Therapeutic strategies that restore BPB populations and butyrate levels, such as prebiotics, dietary fiber, and microbiota-targeted interventions, hold promise for mitigating inflammation and enhancing systemic health through microbiome modulation.
Snodgrass JL et al. · International journal of molecular sciences (2026)
Butyrate supports colonocyte energy metabolism, reinforces epithelial barrier function, regulates goblet cell mucus production, and exerts anti-inflammatory effects via histone deacetylase inhibition and G-protein-coupled receptor signaling.
The depletion of BPB and the resultant butyrate deficiency may represent a unifying pathophysiological mechanism underlying these conditions.
