About this study
This study evaluates the local and systemic inflammatory response in the airway in COPD patients who consume electronic cigarettes compared with conventional cigarette smokers.
Read the detailed description
Chronic obstructive pulmonary disease (COPD) is an illness with high morbidity and mortality in our society with a prevalence of about 10% of the population. Smoking represents the main risk factor for development of COPD having been associated with a greater decrease in lung capacity and increased mortality. Therefore, early treatment of smoking habit is an essential therapeutic approach.
The first line drug treatments have proven effective for smoking cessation, on the other hand the introduction of electronic cigarettes has brought a wide impact on our society,being considered as possible replacements in patients with difficulties in quitting the habit; however there is still limited information on its use in addition to some undesirable effects that have been described such as the lipoid pneumonia.
Recent clinical trials have shown that the use of electronic cigarettes may be associated with symptoms like dry cough, mouth irritation, dyspnea, and headache. On the other hand it has also been associated with increased airway resistance, an immediate decrease of exhaled nitric oxide (FeNO) and FEV1.
Our study aim to assess the inflammatory response in COPD patients who are regular consumers of electronic cigarettes compared with conventional cigarette smokers. The inclusion criteria in the study are: male patients diagnosed with COPD Gold B and C according to international guidelines that are regular smokers with no desire to quit their smoking habit. Exclusion criteria includes those with serious cardiovascular disease, chronic inflammatory disease, active oncologic disease of any origin, use of corticosteroids or other drugs with anti-inflammatory effect and finally COPD patients with acute exacerbation in the last twelve weeks.
Patients will be randomized into two groups: users of conventional and electronic cigarette. All patients in the second group will be provided with the same type of electronic cigarette and doses of inhaled nicotine.
We will perform a complete clinical characterization of the patients collecting data related with their smoking habit, daily consumption, tests to assess the degree of dependence and withdrawal symptoms, level of dyspnea and symptoms associated with tobacco consumption.
We will perform a complete respiratory functional test including spirometry, diffusion capacity and measurement of exhaled carbon monoxide levels. Inflammatory involvement of the airway will be examined by assessing the concentration of exhaled nitric oxide, studying the percentage of neutrophils and eosinophils in induced sputum and a general analysis for determination of inflammatory mediators: IL1B, IL6, IL8, factor alpha and C-reactive protein tumor necrosis.
The results will be evaluated by statistical tests. The results obtained will provide us with information about the effect of the electronic cigarette in COPD and its effectiveness in smoking cessation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| COPD patients & conventional cigarettes | COPD patients regular smokers of conventional cigarettes with no desire to quit smoking habit. | |
| COPD patients & electronic cigarettes | COPD patients who had been users of electronic cigarettes for at least 8 weeks. They will be provided with an specific type of electronic cigarette and the same dosage of inhaled nicotine. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluation of inflammatory response
Assessment of the local inflammatory airway response measured by respiratory functional test and sputum culture, in addition to the evaluation of the systemic inflammatory response provided by determination of acute reactants in blood tests (determination of C-reactive protein and cytokines in blood sample) in COPD patients.
Measured: 8 weeks
Secondary outcomes (2)
Clinical symptoms associated with COPD
Complete characterization of patients: tobacco consumption related symptoms: cough, oral irritation, dyspnoea. Control of the symptoms of nicotine withdrawal and evaluation test.
Measured: 8 weeks
Tobacco withdrawal
Maintained smoking abstinence rate at 8 weeks in the electronic cigarette group.
Measured: 8 weeks

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Obstructive Pulmonary Disease, run by Fundacio Catalana de Pneumologia at 1 site in Spain.
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 2 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 Feb 2020. 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 Spain. 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?
Evaluation of inflammatory response (time frame: 8 weeks). 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 NCT02892396, which also lists 12 linked publications.
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 Feb 2020.
