Inflammation's Impact on Heart Disease and Diabetes (INFO)

January 31, 2025 updated by: University of Aarhus

Inflammation: a Key Contributor to Heart Disease and Diabetes?

The goal of this observational study is to evaluate the inflammatory response associated with cardiometabolic diseases, and whether these can be reduced by ex vivo treatment with therapeutic agents. Briefly, the study involves two populations: healthy volunteers and severely obese patients undergoing weight-loss surgery. The main questions the study seeks to address are:

  1. To investigate if the therapeutic agents modulate the inflammatory response linked to obesity and cardiometabolic disease?
  2. What underlying factors contribute to variations in individual responses?

Researchers will examine differences between healthy participants and those undergoing weight-loss surgery to assess the potential impact of weight loss on responsiveness and overall outcomes.

Participants will:

  • Undergo initial testing to evaluate their baseline response.
  • Provide samples during surgery for further analysis.
  • Participate in follow-up assessments to track changes over time.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The goal of this observational study is to investigate the relationship between treatment responsiveness and inflammation both systemically in blood, and peripherally in tissue biopsies, focusing on its relevance to cardiometabolic disease and associated conditions. The study aims to develop a predictive model to identify individuals most likely to benefit from anti-inflammatory treatments, thus supporting personalized therapeutic strategies.

Main research questions:

  1. To investigate if the therapeutic agents modulate the inflammatory response linked to obesity and cardiometabolic disease
  2. To determine the underlying factors that contribute to variations in individual responses to anti-inflammatory drugs

Study design:

The study will involve two participant groups:

  • Healthy control group, composedrised of normal weight individuals
  • Obese adult patients, scheduled to undergo bariatric surgery.

Participant procedures:

  • Baseline testing: An initial test will evaluate treatment responsiveness.
  • Tissue sampling: Tissue biopsies are obtained during surgery and undergo detailed analyses, including ex vivo treatments
  • Follow-up assessments: Participants will be reassessed a year after surgery to evaluate long-term outcomes.

Methods:

  • Molecular studies: Whole blood and peripheral tissue biopsies (adipose tissue, liver, muscle and intestinal biopsies) will be analyzed to identify cellular and molecular pathways associated with treatment responsiveness.
  • Predictive modeling: Clinical, molecular, and biochemical data will be integrated to create a model predicting individual responsiveness.
  • Insulin sensitivity analysis: Advanced imaging techniques will measure tissue-specific glucose uptake.

Hypotheses: Impaired ability to regulate the inflammatory response correlates with cardiometabolic disease.

Anticipated Outcomes:

The study seeks to support precision medicine approaches for addressing cardiometabolic disease.

This research builds on previous findings about the role of inflammation in cardiometabolic dysfunction. By differentiating responders from non-responders, the study aims to support targeted therapeutic strategies for inflammation and cardiometabolic health.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Healthy controls and obese patients, scheduled to undergo bariatric surgery without a pre-surgical diet

Description

Inclusion Criteria:

  • Individuals willing and able to give appropriate oral and written informed consent
  • Men and women over 18 years of age.
  • Correct body mass index (BMI) (Lean controls: 18.5-24.9 kg/m2. Obese gastric bypass patients: 35-50 kg/m2)

Exclusion Criteria:

  • The individual does not follow instructions given in the research study.
  • Pregnancy.
  • Significant gastrointestinal problems.
  • Use of tobacco.
  • The individual consumed alcohol within two days prior to the study visit

  • Use of dietary supplements that impact the inflammatory resolution process (e.g., fish oils), and the person is not willing to discontinue the use of the supplements 1 week prior to the visits.
  • Underlying cardiometabolic disease, or medication related to such disease (e.g., blood pressure medication, insulin to treat diabetes, etc.).
  • Underlying inflammatory disease, or medication related to such disease.
  • The individual states that they have increased bleeding tendency or are using anti-coagulant (blood-thinning) medication.
  • For obese patients only: The individual has lost more than 8% of his/her body weight since their clinical referral for surgery or has lost more than 3% of his/her body weight in the 4 months leading up to surgery.
