Trial summary

Exposure to Aspergillus spores is associated with symptoms of asthma or airway inflammation (Chaudhary \& Marr, 2011; Smith \& Denning, 2011), leading to the possible onset of severe fungal complications with acute or chronic inflammation. Read more about this study

About this study

Official title: Evaluation of the Relationship Between the Degree of Environmental Fungal Exposure in Patients' Dwellings and Clinical Symptoms of Patients With Chronic Obstructive Pulmonary Disease - Study of Feasibility

Exposure to Aspergillus spores is associated with symptoms of asthma or airway inflammation (Chaudhary \& Marr, 2011; Smith \& Denning, 2011), leading to the possible onset of severe fungal complications with acute or chronic inflammation. In patients with chronic obstructive pulmonary disease (COPD), whose main etiological factor is cigarette smoke, A. fumigatus sensitization has been reported to be related to poor lung function (Bafadhel et al., 2014). Besides, COPD patients with fungal sensitization exhibit greater granulocyte count, implying more severe inflammation (Agarwal, Gaur, \& Chowdhary, 2015). Fungal cultures from sputum are frequently positive in patients with asthma or with COPD (Pashley, 2014). Fungal colonization and infection have also been suspected to be related to exacerbations of COPD, but their potential role in the pathogenesis of COPD is poorly understood (Bafadhel et al., 2014). The hypothesis is that patients with COPD have a worsening of their pulmonary symptoms after exposure to fungal spores. This study will ensure the feasibility of quantifying environmental fungal exposure in patients' dwellings. For this, an electrostatic wipe will be deposited in the living room and another one in the bedroom for 12 weeks. The wipes will be analyzed by the mycology laboratory of the Croix Rousse hospital.

If the results of this first study are conclusive, it is planned to continue this analysis with a regional multicentre study.

What participants receive

    The main objective will be to study the feasibility of the quantification of domestic fungal exposure with electrostatic wipe. The interval of environmental fungal exposure quantification values measured by conventional mycology and by NGS will be established, with analysis of the correlation between the quantification obtained by the two techniques.

    For this, an electrostatic wipe will be deposited in the living room and another one in the bedroom for 12 weeks. The wipes will be analyzed by the mycology laboratory of the Croix Rousse hospital.

What is being measured

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

  1. Quantification of domestic fungal exposure.

    The main judgment criterion will be to study the feasibility of the quantification of domestic fungal exposure.

    Fungal diversity exposure will be analyzed by mycological culture and next-generation sequencing.

    The interval of environmental fungal exposure quantification values measured by conventional mycology and by Next Generation Sequençing will be established, with analysis of the correlation between the quantification obtained by the two techniques.

    Measured: 12 weeks after inclusion.

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Obstructive Pulmonary Disease, run by Hospices Civils de Lyon at 1 site in France.

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 8 inclusion and 9 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 19 Jul 2023. 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 France. 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?

Quantification of domestic fungal exposure. (time frame: 12 weeks after inclusion.). 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 19 Jul 2023.
