Background: Numerous inflammatory skin diseases are associated with the gut microbiota. Studies of the association between gut microbiota and inflammatory skin diseases have yielded conflicting results owing to confounding factors, and the causal relationship between them remains undetermined.
Methods: Two-sample Mendelian randomization (MR) was used to examine the association between gut microbiota and four common inflammatory skin diseases: acne, psoriasis, urticaria and atopic dermatitis. The summary statistics of the gut microbiota from the largest available genome-wide association study meta-analysis (n = 13,266) conducted by the MiBioGen consortium along with the summary statistics of the four diseases were obtained from the FinnGen consortium. Causal relationships were assessed using the inverse variance weighted (IVW), weighted median, MR-Egger and maximum likelihood methods, and several sensitivity analyses were performed to ensure the accuracy of the results. Finally, reverse and multivariable MR analyses were performed to verify the robustness of the results.
Results: We found causal associations of Bacteroidaceae [odds ratio (OR), 2.25; 95% confidence interval (CI), 1.48-3.42; p = 0.0001], Allisonella (OR, 1.42; 95% CI, 1.18-1.70; p = 0.0002) and Bacteroides (OR, 2.25; 95% CI, 1.48-3.42; p = 0.0001) with acne, the Eubacterium fissicatena group with psoriasis (OR, 1.22; 95% CI, 1.10-1.35; p = 0.0002) and Intestinibacter with urticaria (OR, 1.28; 95% CI, 1.13-1.45; p = 0.0001). These results were corrected for a false discovery rate. Sensitivity analyses were performed to validate the robustness of the associations and reverse MR confirmed that the results were not influenced by the reverse effect.
Conclusion: Our study revealed that some gut microbiota are risk factors for inflammatory skin diseases, providing new information on potential therapeutic targets. Additionally, a possible association with the gut-skin axis was confirmed. Further research is required to elucidate the mechanisms underlying these relationships.

Probiotics as green inputs have been reported to regulate metabolism and immunity of fish. However, the mechanisms by which probiotics improve growth and health of fish are unclear. Therefore, the aim of this study was to investigate the effect of Bacillus subtilis HGCC-1, an indigenous probiotic isolated from fish, on growth performance, host lipid metabolism, liver inflammation and gut microbiota of golden pompano.

Background: The conversion of primary bile acids to secondary bile acids by the gut microbiota has been implicated in colonic inflammation. This study investigated the role of gut microbiota related bile acid metabolism in colonic inflammation in both patients with inflammatory bowel disease (IBD) and a murine model of dextran sulfate sodium (DSS)-induced colitis.
Methods: Bile acids in fecal samples from patients with IBD and DSS-induced colitis mice, with and without antibiotic treatment, were analyzed using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS).

Background And Hypothesis: Gut dysbiosis characterized by an imbalance in pathobionts (Enterobacter, Escherichia and Salmonella) and symbionts (Bifidobacterium, Lactobacillus and Prevotella) can occur during chronic kidney disease (CKD) progression. We evaluated the associations between representative symbionts (Bifidobacterium and Lactobacillus) and pathobionts (Enterobacteriaceae) with kidney function in persons with autosomal dominant polycystic kidney disease (ADPKD).
Methods: In this cross-sectional study, 29 ADPKD patients were matched to 15 controls at a 2:1 ratio.

Objective: Summaries of the relationships between the microbiota and liver cirrhosis and their conclusions are not consistent. This study describes microbial differences in patients with liver cirrhosis by performing a meta-analysis.
Methods: We searched PubMed, Embase, Web of Science, and the Cochrane Library and collected related articles published before March 10, 2024.

The absence of suitable intervention significantly increases the likelihood of type 2 diabetes mellitus (T2DM) development in people with prediabetes. Recent statistical findings indicate that the gut microbiome might influences the development of insulin resistance. The objective of our study was to assess the efficacy and safety of probiotic supplementation in individuals diagnosed with prediabetes.
