ABSTRACT Background and Aim We aimed to investigate whether gut microbiota could predict the treatment response pharmacological agents among metabolic dysfunction‐associated steatotic liver disease (MASLD) patients without diabetes mellitus (DM), as data are lacking. Methods prospectively followed up non‐diabetic MASLD who used empagliflozin. Clinical, anthropometric, laboratory assessments magnetic resonance imaging‐proton density fat fraction (MRI‐PDFF) were performed from baseline week 52 (EOT). Baseline stool samples collected, shotgun DNA metagenomic sequencing was profile microbiome. The primary outcome empagliflozin at EOT, defined MRI‐PDFF decline ≥ 30% EOT baseline. Linear discriminant analysis [LDA] effect size identify putative bacterial species. Multivariable logistic regression derive adjusted odds ratio (aOR) of with species by adjusting for clinical factors. Results Twenty‐two (48.9%) 45 (median age: 56.9 years [IQR: 51.0–63.2]; male: 23 [51.1%]) achieved EOT. There difference in alpha diversity (Shannon index: p < 0.001; Simpson = 0.001) beta ( 0.048) microbiome between non‐response groups.

Conclusions Certain species, particularly combination , butyriciproducens, may MAFLD DM.

Vaccination plays a critical role in public health by reducing the incidence and prevalence of infectious diseases. The efficacy vaccine has numerous determinants, which include age, sex, genetics, environment, geographic location, nutritional status, maternal antibodies, prior exposure to pathogens. However, little is known about gut microbiome how it can be targeted through dietary interventions improve immunological responses. Unveiling this link imperative, particularly post-pandemic world, considering impaired COVID-19 response observed dysbiotic individuals. Therefore, article aims comprehensively review diet probiotics modulate composition, linked efficacy. Dietary fiber polyphenolic compounds derived from plant-based foods microbial diversity promoting growth short-chain fatty acids-producing microbes. On other hand, animal-based have mixed effects – whey protein fish oil promote eubiosis In contrast, lard red meat adverse effects. Studies further indicate that probiotic supplements exert varied effects, mostly strain dosage-specific. Interlinking diet, microbiome, probiotics, vaccines will reveal opportunities for newer research on diet-induced microbiome-manipulated precision vaccination strategies against
