About this study

To study Fibrocytes in patients with Rheumatoid Arthritis, Interstitial lung disease and severe asthma and healthy controls.

Read the detailed description

Objectives: 1) To demonstrate that circulating CD45+ CD34+ CD11b+ cells can express Procollagen 1 and thereby show that these markers can be used to identify circulating fibrocytes. 2) To measure the levels of circulating CD45+, CD34+, CD11b+ cells in patients with RA, Fibrotic ILDs, severe asthma and in healthy controls (HC). 3) To compare the levels with number of peripheral blood mononuclear cells (PBMC) that differentiate to mature fibrocytes in vitro.

Method: The CD45+, CD34+, CD11b+ cells from 4 patients were isolated by cell sorting, and stained for Procollagen. 30 patients (10 of each RA, fibrotic ILDs: IPF or non-specific interstitial pneumonitis (NSIP), severe asthma) and 10 HC were included. Current medication, disease activity, lung function and radiographic data were collected. In 100 µL of lysed blood cells were enumerated by flowcytometry. Further, PBMC were isolated and cultured for 5 days. Coverslips from two wells were stained and mature fibrocytes counted and reported as fibrocytes per 106 PBMC originally added to the well.

Study groupRoleWhat they receive
Fibrocyte measurement and lung function testExperimentalAll participants has a peripheral blood sample taken, where fibrocytes are measured using flowcytometry. Further peripheral blood mononuclear cells (PBMC) are isolated and cultured. All, except healthy controls, have their lung function measured.

What is being measured

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

  1. Measure fibrocytes in peripheral blood.

    To measure the levels of circulating CD45+, CD34+, CD11b+ cells (cells/uL) in patients with RA, Fibrotic ILDs, severe asthma and in healthy controls (HC).

    Measured: Baseline

Secondary outcomes (3)
  1. Compare circulating CD45+, CD34+, CD11b+ cells (cells/uL) with number of fibrocytes in cultured cells (fibrocytes/cultured peripheral blood mononuclear cells).

    To compare the levels of circulating CD45+, CD34+, CD11b+ cells (cells/uL) with number of peripheral blood mononuclear cells (PBMC) that differentiate to mature fibrocytes in vitro.

    Measured: Baseline

  2. Fibrocytes and lung diffusion capacity.

    Is the level of fibrocytes in peripheral blood (cells/uL) correlated signs of interstitial lung disease in a lung function measured by diffusing capacity for carbon monoxide (DLCO) (mmol CO per min per kPa).

    Measured: Baseline

  3. Fibrocytes and rheumatoid arthritis

    Is the level of fibrocytes in peripheral blood (cells/uL) correlated to disease activity in rheumatoid arthritis, measured by disease activity score in 28 joints (DAS28).

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A study testing Fibrocyte measurement and lung function test. in people with Interstitial Lung Diseases and Rheumatoid Arthritis, run by Odense University Hospital at 1 site in Denmark.

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 5 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: finished, as of the sponsor's last update on 21 Apr 2017. 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 Denmark. 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?

Measure fibrocytes in peripheral blood. (time frame: Baseline). 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 NCT02711657, 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 21 Apr 2017.
