About this study

The purpose of the study is to determine the characteristics of patients with diabetes and sarcoidosis and to compare them with those of patients with diabetes and no sarcoidosis. The investigators will approach these aims by measuring hemoglobin A1c, C peptide, insulin levels, and 2-hour glucose tolerance test results on the study population as well as collecting clinical data from records. Three groups of patients will be identified from pulmonary and endocrinology clinics at the University of Alabama at Birmingham. The first group will have a diagnosis of sarcoidosis without diabetes, the second group will have a diagnosis of both sarcoidosis and diabetes, and the third group will have a diagnosis of diabetes without sarcoidosis. Sample size is not pre-determined, but investigators anticipate this number to be less than 100. These patients will be asked in person during an office visit to join the study. For each patient who agrees to join, at a clinic visit, investigators will review and sign consent. Following the visit or at a time convenient for each patient, study subjects will undergo a fasting plasma venous sample collection for a hemoglobin A1c, C peptide, insulin level and perform a 2-hour oral glucose tolerance test. The degree of glucose intolerance and prevalence of diabetes will be analyzed and compared between the groups and to historical published control data via T test comparisons. At a later separate visit, patients recruited will undergo ultrasound of the pancreas to assess pancreatic size and morphology.

    Venous blood samples will be obtained for hemoglobin A1c, C peptide, insulin level, and 2-hour fasting glucose tolerance test.

  • Ultrasound of pancreasDiagnostic test

    Ultrasound of pancreas will be obtained on all study participants.

Questions about this trial

What is this clinical trial studying?

An observational study of Sarcoidosis and Diabetes Mellitus, run by University of Alabama at Birmingham at 1 site in United States.

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 1 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The record says: withdrawn, as of the sponsor's last update on 13 Dec 2019. 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 United States. 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 was withdrawn before enrolling participants, so there are no results.

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?

Change in glucose during oral glucose tolerance test (oGTT) (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Dec 2019.
