Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

The inclusion criteria were: age > 18 years, imaging ultrasound-based evidence of hepatic steatosis, and clinical and biochemical features configuring MD (at least one of: obesity, type 2 diabetes, dyslipidemia, or essential arterial hypertension diagnosis).

All patients who were potentially considered eligible received TE evaluation with the LSM definition. Importantly, patients with AF (TE-assessed LSM confirming >F3) were excluded. This choice was motivated by evidence that in AF, IP is significantly altered, contributing to an enhanced bacterial translocation, both events influenced by the potential presence of portal hypertension Other exclusion criteria were: (a) chronic liver disease (CLD) of other etiology [hepatitis B and/or C virus, alcohol-related liver disorder (ALD) with evidence of alcohol abuse history assessed by using the Alcohol Use Disorders Identification Test questionnaire, hemochromatosis, Wilson's disease, or cholestatic liver disorders]; (b) evidence of cancer, including hepatocellular carcinoma (HCC); (c) acute systemic infections; (d) pregnancy; (e) psychological/psychiatric problems potentially invalidating the informed consent and/or conditions impacting the ability to adhere to dietary recommendations and intervention protocol; (f) chronic kidney disease (with Estimated Glomerular Filtration Rate - eGFR- <30 ml/min); (g) the use (ongoing and/or in the 3 months preceding the enrollment) of drugs/supplements that could influence IP (e.g., probiotics, antibiotics, NSAIDs).

About this study

Official title: Exploring Effects of Long-lasting Bicarbonate-Sulfate-Calcium-Magnesium Water Intake on Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)-Related Outcomes Via Impacting Intestinal Permeability (IP), IP-related Systemic Inflammation, and Oxidative Stress.

Background: Fonte Essenziale®, a mineral water rich in bicarbonate, sulphate, 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.

MASLD patients will be consecutively endoller and randomized into two groups: group A receiving 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) will be 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 will indicate hepatic steatosis improvement.

Read the detailed description

This will be a prospective, randomized, controlled clinical trial conducted at the Hepatogastroenterology Division of the University of Campania "Luigi Vanvitelli" (Naples, Italy). The study will be designed and implemented under the framework of the Ferrarelle-Vanvitelli research agreement (n. 390-01583577-30059 - dated 09/02/2023), which previously enabled the investigation of mineral water as a non-pharmacological intervention in chronic liver disease.

Patients meeting the diagnostic criteria for MASLD [17] will be consecutively screened for potential eligibility. All individuals considered potentially eligible will undergo Transient Elastography (TE) with Liver Stiffness Measurement (LSM) to exclude those with LSM-defined advanced fibrosis (AF) (> F3).

Eligible participants will then be randomized in a 1:1 ratio into two study arms: Group A and Group B. Group A will receive 400 ml/day of Fonte Essenziale® mineral water, administered each morning on an empty stomach for 12 consecutive months, in addition to a specialist-prescribed controlled nutritional regimen (see dedicated subsection), followed by a 6-month washout period during which only the nutritional regimen will be maintained. Group B will follow the same 12-month nutritional protocol without water supplementation. The selected water dose and fasting administration will be based on the original protocol and prior studies, given that gastric emptying is accelerated and absorption more consistent under fasting conditions, potentially enhancing mucosal interaction.

Three study time-points will be defined: baseline (T0), after 12 months (T12), and post-washout (T18), the latter applicable only to Group A. At each time-point, anthropometric, clinical, and demographic data-including age, sex, smoking status, MASLD-related comorbidities, and Body Mass Index (BMI)-will be collected, alongside routine biochemical parameters and TE-derived liver disease progression metrics, including both LSM-defined fibrosis staging and Controlled Attenuation Parameter (CAP)-based steatosis grading. At T12, a ≥30% reduction in baseline CAP values will be considered indicative of steatosis improvement.

Additionally, at each time-point, following the collection of 20 ml serum and 200 mg fecal samples, intestinal permeability (IP) will be assessed via a biomarker panel comprising fecal zonulin (ng/ml), serum LPS-binding protein (LBPp) (µg/ml), indicative of systemic endotoxin exposure, and serum occludin and claudin-1 (ng/ml), representing epithelial tight-junction integrity. At T0, concurrent fecal zonulin >110 ng/ml and serum LBPp >10 µg/ml will define increased IP (in-IP) [6,13]. At T12, improvement in IP (im-IP) will be defined by simultaneous reductions in fecal zonulin <110 ng/ml and serum LBPp <10 µg/ml. This dual-marker approach will be adopted to enhance diagnostic reliability, as single biomarkers may inadequately reflect barrier integrity and function.

IP-associated systemic inflammation (SI) will be evaluated at all time-points by measuring circulating LPS (ng/ml) and pro-inflammatory cytokines [interleukin (IL)-1β, IL-6, and Tumor Necrosis Factor alpha (TNF-α), pg/ml]. Finally, systemic oxidative stress will be assessed using the Biological Antioxidant Potential (BAP) and derivatives of Reactive Oxygen Metabolites (dROM) tests, both validated tools in chronic liver disease contexts.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intestinal permeability changes (time frame: T0-T12 (after the 12 months of intervention)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07211113, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
