About this study

Official title: Changes in the Hypothalamic-pituitary Region of Patients With Metabolic Syndrome and Obesity

This study aims to identify new morphological and quantitative magnetic imaging parameters of pituitary gland and sellar region in overweight and obese patient at baseline and after 3 years, dividing patients in 3 groups (weight loss through diet and lifestyle changes, weight loss through bariatric surgery, no weight loss)

Read the detailed description

This longitudinal prospective study in overweight and obese patients aims to identify and characterize new morphological and quantitative MRI parameters of pituitary gland and sellar region assessed by texture analysis with a specific software (ImageJ©). These parameters will be correlated them to hypothalamic-pituitary-peripheral axis function, metabolism and body composition.

Data will be detected at baseline and at 3 years follow-up to quantitatively identify the different pituitary MRI patterns in 3 groups:

  1. patients without weight modifies
  2. patients with weight loss obtain through diet and lifestyle changes
  3. patients with weight loss obtained through bariatric surgery
Being tested
Bariatric surgery, Diet and lifestyle changes

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bariatric surgeryProcedure or surgery

    Also called sleeve gastrectomy, gastric bypass, bilio-intestinal bypass

  • Diet and lifestyle changesBehavioural

    Also called hypocaloric diet, physical exercise

Study groups in NCT03458533
Study groupRoleWhat they receive
Group 1Obese patients with indication to bariatric surgery
Receives: Procedure: Bariatric surgery
Group 2Overweight or obese patients without indication to bariatric surgery, able to obtain weight loss trough diet and lifestyle changes
Receives: Behavioral: Diet and lifestyle changes
Group 3Overweight or obese patients without indication to bariatric surgery, not able to obtain weight loss trough diet and lifestyle changes
Receives: Behavioral: Diet and lifestyle changes

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pituitary volume

    Change in pituitary volume (mm3) from baseline to 3 years

    Measured: 0, +3 years

Secondary outcomes (4)
  1. Evaluation of pituitary mean and standard deviation intensity

    Changes in new quantitative magnetic imaging parameters of pituitary gland from baseline to 3 years

    Measured: 0, +3 years

  2. Correlation of magnetic resonance parameters with anthropometric measurements

    Correlation analysis of pituitary mean and standard deviation intensity with anthropometric measurements

    Measured: 0, +3 years

  3. Correlation of magnetic resonance parameters with pituitary axis function

    Correlation analysis of pituitary mean and standard deviation intensity with pituitary axis function

    Measured: 0, +3 years

  4. Correlation of magnetic resonance parameters with glyco-metabolic status

    Correlation analysis of pituitary mean and standard deviation intensity with glyco-metabolic status

    Measured: 0, +3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Overweight and Obesity and Metabolic Syndrome, run by University of Roma La Sapienza at 1 site in Italy.

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

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. 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 6 Dec 2022. 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?

Pituitary volume (time frame: 0, +3 years). 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 NCT03458533, 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2022.
