Brief Summary

The investigators seek to analyze the samples provided by patients with obesity-associated fatty liver disease at the multi-omics level and to integrate the results with clinical information, genotypic variants, and factors influencing inter-organ crosstalk. The main aim is to improve the interpretation of fatty liver disease associated with obesity and diabetes by developing predictive models built with algorithms from artificial intelligence. The challenge is to decipher the flow of information by exploring contributing factors, proximate causes of regulatory defects, and maladaptive responses that may promote therapeutic approaches.

Study Arms (3)

Severe obesity without liver disease

Patients with severe obesity who did not meet the criteria described in Kleiner et al. (2005) for nonalcoholic steatohepatitis diagnosis (score 0-2).

Diagnostic Test: To propose diagnostic tests for liver diseases before surgical decisions.

Severe obesity with liver disease without criteria for steatohepatitis

Patients with severe obesity who did not meet the criteria described in Kleiner et al. (2005) for nonalcoholic steatohepatitis diagnosis, but their biopsies presented some liver severity (scores 3 and 4).

Diagnostic Test: To propose diagnostic tests for liver diseases before surgical decisions.

Severe obesity with well-defined steatohepatitis and/or cirrhosis

Patients with severe obesity who met the criteria described in Kleiner et al. (2005) for nonalcoholic steatohepatitis diagnosis (score 5-8).

Diagnostic Test: To propose diagnostic tests for liver diseases before surgical decisions.

Interventions

Observational although patients are candidates for metabolic surgery.

Also known as: External follow up monitoring liver diseases and weight loss.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Participants are consecutive patients with obesity type II or III attending the bariatric surgery unit for treatment. In this center, women are more frequent than men. The average age is 49 (interquartile range 41 - 58). Steatohepatitis (\~30 percent), type 2 diabetes mellitus (\~40 percent), hypertension (\~60 percent), and dyslipidemia (\~35 percent) are the most prevalent comorbidities. Other common ailments are obstructive sleep apnea (\~20 percent) and hypothyroidism (\~10 percent).

You may qualify if:

  • Body mass index greater or equal to 40 kg/m\^2.
  • Body mass index between 35 and 40 kg/m\^2 with high-risk comorbidities (diagnosis or treatment for hypertension, dyslipidemia, or type 2 diabetes mellitus).
  • Positive psychiatric evaluation.
  • Age greater or equal to 18 years old.

You may not qualify if:

  • Legal or illegal drug consumption, including alcohol.
  • Diagnosis of Hepatitis.
  • Current cancer diagnosis or treatment.
  • Clinical or analytical evidence of severe illness.
  • Clinical or analytical evidence of chronic or acute inflammation.
  • Clinical or analytical evidence of infectious diseases.
  • Clinical or analytical evidence of terminal illness.

The Data Management Plan makes data fully findable, accessible, interoperable, and reusable, following the indication of the Horizon 2020 initiative of the European Union. The clinical team identified sensitive data, including epidemiological, anthropometric, and medical information. It is the only responsibility of the principal investigator to ensure that sensitive data are de-identified, implementing technical safeguards to guarantee anonymity. Most data will be experimental and obtained from the analysis of column value and data format description (.txt or .csv) and syntax scripts (.R). The external collaborators, especially those involved in validation cohorts, may have access to data upon request. With the acceptance of the principal investigator, Rovira i Virgili University's institutional service will guarantee digital access to repositories with raw data generated in research analyses.
