Special Issue Information

Dear Colleagues,

Emerging evidence suggests the crucial role of nutrients and intestinal barrier alteration in the pathogenesis of dysmetabolic chronic liver disorders (CLDs), particularly metabolic dysfunction-associated steatotic liver disease (MASLD).

In the era of precision medicine, nutrigenetic/genomic approaches have progressively shown the active role of nutrients, revealing the mutual relationship between dietary elements and metabolic processes. Relevant findings have identified “pro-inflammatory” foods, elucidating their capability to disrupt immune pathways, ultimately promoting phlogosis and oxidative stress at local, hepatic, and systemic levels. Complementarily, the alteration of the bowel integrity barrier (“leaky gut”), which contributes to the crossing of substances, dramatically impacts this picture. Gut microbiota appears as a key regulator, influencing both nutrient transformation processes and intestinal permeability.

This Special Issue aims to provide new evidence about the complex relationship between gut microbiota, nutrition, and intestinal permeability in MASLD and dysmetabolic CLDs

Special attention will be given to studies elucidating the traits linking nutrients with the intestinal barrier’s homeostasis in this setting.

Manuscript submissions may include original research articles (clinical, translational, or basic research) and systematic reviews.

“From Bench to Bedside”, these studies can provide the basis for designing promising and effective management strategies for MASLD and dysmetabolic CLDs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Background/Objectives: Fonte Essenziale®, a mineral water rich in bicarbonate, sulfate, calcium, and magnesium, has shown potential in modulating the gut–liver axis and microbiota in hepatic steatosis. However, its long-term effects on intestinal permeability (IP), systemic inflammation (SI), and oxidative stress—key factors in Metabolic dysfunction-associated steatotic liver disease (MASLD)—remain unexplored. Methods: Eighty-seven MASLD patients were randomized into two groups: group A received Fonte Essenziale® (400 mL/day, fasting) plus a controlled nutritional regimen for 12 months, followed by a 6-month water washout; group B followed only the controlled nutritional regimen. IP markers, SI (IL-1β, IL-6, TNF-α), oxidative stress (dROMs/BAP), and clinical data (including Controlled Attenuation Parameter—CAP) were assessed at baseline (T0), 12 months (T12), and post-washout (T18). Baseline increased IP (in-IP) was defined by fecal zonulin > 110 ng/mL and serum LBPp > 10 µg/mL; improvement (im-IP) required normalization of both. A ≥30% CAP reduction indicated steatosis improvement. Results: Thirty-eight patients in group A and thirty-nine in group B completed the study. At T12, group A showed significant reductions in fecal zonulin (p: 0.0163) and serum LBPp (p < 0.0001), with increased occludin and claudin 1 (all p < 0.0001). Im-IP prevalence was higher in group A (p: 0.0037). Group A also showed significant reductions in IL-1β, TNF-α, IL-6, LPS, and dROM/BAP (all p < 0.05), especially among those with im-IP. CAP, insulin, and HDL levels improved significantly (all p < 0.0001). Multivariate analysis confirmed water intake (aOR: 2.185, p: 0.001) and im-IP achievement (aHR: 1.267, p: 0.021) as predictors of steatosis improvement. Benefits persisted at T18. Conclusions: Prolonged Fonte Essenziale® intake improved hepatic steatosis and MASLD outcomes by modulating IP, SI, and oxidative stress. This trial has been registered on clinicaltrials.gov (NCT07211113). Full article
