Morphological Pancreatic Features in Diabetes Mellitus Type 2 (PANDIAM)

February 28, 2023 updated by: J. Enrique Domínguez-Muñoz, Hospital Clinico Universitario de Santiago

Morphological Features of the Pancreas in Patients With Type 2 Diabetes Mellitus: Correlation With Clinical Features of the Disease.

Hypothesis: Type 2 diabetes mellitus is associated with pancreatic fibrosis that can be evaluated by minimally invasive imaging techniques. That fibrosis is associated with alteration of exocrine pancreatic function, defined as a reduced secretion of pancreatic enzymes and the development of nutritional deficiencies.

To test that hypothesis, a prospective, observational, cross-sectional, comparative, case-control study has been designed.

Pancreatic fibrosis will be evaluated by endoscopic ultrasound and quantitative elastography in cases (type-2 diabetes) and age-gender-matched controls without diabetes.

Pancreatic function will be explored by fecal elastase test and nutritional evaluation.

Calculated sample size is 94 patients (47 cases and 47 controls). Study period is 2 years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Anticipated)

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adult diabetic (patients) and nondiabetic (controls) undergoing endoscopic ultrasound for indications other than evaluation of the pancreas due to suspected or known pancreatic disease.

Description

Inclusion Criteria:

  • Patients older than 18 years.
  • Undergoing an upper endoscopic ultrasound for any indication other than pancreatic disease.
  • Signed informed consent-
  • Patients: Previous diagnosis of type-2 diabetes mellitus.
  • Controls: Nondiabetic subjects, matched by age, gender, alcohol consumption, and smoking with patients.

Exclusion Criteria:

  • History of pancreatic disease or surgery.
  • History of upper gastrointestinal surgery.
  • Diabetes type other than type-2.
  • Severe cardiovascular or respiratory disease.
  • Lack of informed consent.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Case
Cases are adult patients with type-2 diabetes, who undergo endoscopic ultrasound examination for any non-pancreatic indication.
Diagnostic test: Endoscopic ultrasound
Evaluation of pancreatic fibrosis by endoscopic ultrasound and elastography. Evaluation of exocrine pancreatic function by fecal elastase-test and nutritional evaluation.
Other Names:
  • Fecal elastase test
  • Nutritional evaluation
Control
Controls are adult, non-diabetic patients, who undergo endoscopic ultrasound examination for any non-pancreatic indication.
Diagnostic test: Endoscopic ultrasound
Evaluation of pancreatic fibrosis by endoscopic ultrasound and elastography. Evaluation of exocrine pancreatic function by fecal elastase-test and nutritional evaluation.
Other Names:
  • Fecal elastase test
  • Nutritional evaluation

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Degree of pancreatic fibrosis
Time Frame: Day 1
Evaluation of the degree of pancreatic fibrosis by endoscopic ultrasound and elastography.
Day 1
Degree of impairment of exocrine pancreatic function
Time Frame: Up to 7 days
Quantification of fecal elastase and evaluation of the nutritional status
Up to 7 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Prevalence of pancreatic atrophy
Time Frame: Day 1
Size of the pancreas as evaluated by endoscopic ultrasound
Day 1
Factors associated with pancreatic fibrosis
Time Frame: Day 1
Demographics and clinical data significantly associated with pancreatic fibrosis
Day 1

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 3, 2022

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
