Inflammatory Profiling in Chronic Lung Disease

April 15, 2024 updated by: Ludwig Boltzmann Institute for Lung Vascular Research
The aim of this study is to investigate the underlying inflammatory profile in patients with chronic lung disease and determine the association pulmonary hypertension.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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

Chronic lung diseases (CLD), such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) are often complicated by the presence of pulmonary hypertension (PH), where even a mild elevation of blood pressure in the pulmonary arteries is associated with an even poorer prognosis. In this study, we will investigate whether similarities exist in the inflammatory profile that could potentially underlie all forms of pulmonary hypertension. Inflammatory data will be generated using flow cytometry, expression profiling and histological analysis and compared to the associated clinical data.

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

Sampling Method

Non-Probability Sample

Study Population

Subjects undergoing lung transplantation at the Medical University of Vienna

Description

Inclusion Criteria:

  • Patients undergoing lung transplant with COPD or IPF, with associated PH
  • Signed informed consent

Exclusion Criteria:

  • patients without written informed consent
  • Signs of any infection such as pneumonia, pulmonary tuberculosis or infections with pleural effusions.

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.
COPD-PH group
Patients with confirmed COPD and pulmonary hypertension
Other: Tissue sampling

Blood collection via venipuncture into citrate- or ethylenediaminetetraacetic (EDTA)-containing vacutainer tubes and into serum tubes. Explant lung tissue obtained from patients that underwent lung transplantation.

Non-transplanted donor lungs that had been harvested for transplantation, but not implanted because of size-reduction serve as controls.
IPF-PH
Patients with confirmed pulmonary fibrosis and pulmonary hypertension
Other: Tissue sampling

Blood collection via venipuncture into citrate- or ethylenediaminetetraacetic (EDTA)-containing vacutainer tubes and into serum tubes. Explant lung tissue obtained from patients that underwent lung transplantation.

Non-transplanted donor lungs that had been harvested for transplantation, but not implanted because of size-reduction serve as controls.
Control group
Control group without diagnosed COPD, IPF, or pulmonary hypertension
Other: Tissue sampling

Blood collection via venipuncture into citrate- or ethylenediaminetetraacetic (EDTA)-containing vacutainer tubes and into serum tubes. Explant lung tissue obtained from patients that underwent lung transplantation.

Non-transplanted donor lungs that had been harvested for transplantation, but not implanted because of size-reduction serve as controls.

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
Analysis of inflammatory cell profile
Time Frame: within 36 months

The number of leukocytes (CD45+ cells) and derivatives (percentage lymphocytes, monocytes and neutrophils) will be measured by flow cytometry in explanted lung tissue and blood of patients with CLD-PH and controls.

Values will be reported as %CD45+ and %total cells.
within 36 months

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
Degree of pulmonary vascular disease
Time Frame: within 36 months

Pulmonary vascular disease will be assessed by associated clinical data (mPAP (mmHg), PVR (WU))

  1. CLD without PH (mPAP <21 mmHg, or mPAP 21-24 mmHg with pulmonary vascular resistance (PVR) <3 Wood Units (WU)).
  2. CLD with PH (mPAP 21-24 mmHg with PVR ≥3 WU, or mPAP 25-34 mmHg) (CLD-PH).
  3. CLD with severe PH (mPAP ≥35 mmHg, or mPAP ≥25 mmHg with low cardiac index (<2.0 L·min-1·m-2)) (CLD-severe PH).

Study record dates

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.

Primary Completion (Estimated)

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.
