Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 4 to 8 years
- All sexes
- No healthy volunteers
- Child
Who may be able to join
- a group of children (n=90) suffering from CRS (fulfilling the EPOS criteria, European Position Paper on Rhinosinusitis and Nasal Polyps) and asthma (fulfilling the API criteria, Asthma Predictive Index), including a 30-person subgroup diagnosed with clinically significant IgE-dependent hypersensitivity (accordance between symptoms and current exposure to sensitizing allergen),

About this study
Official title: The Role of Nonspecific Immune Response of the Airway Mucosa in Children With Chronic Rhinosinusitis and Asthma
The project is intended to be realised in two phases. In the first stage, a case control study will be performed. In the second phase, double-blind, placebo controlled study will be conducted. In the first phase 3 groups of children will be compare: i) a group of children suffering from chronic rhinosinusitis (CRS) (fulfilling the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) criteria) and asthma (fulfilling the Asthma Predictive Index (API) criteria) (CRS+/asthma+, n=90), ii) a group of children suffering from CRS (fulfilling the EPOS criteria) but without asthma symptoms (negative API criteria) (CRS+/asthma-, n=30) and iii) a group of children without symptoms of CRS (negative EPOS criteria) and without asthma symptoms (negative API criteria) (CRS-/asthma-, n=30). In the second phase the effect of intranasal glucocorticosteroids will be assessed. The following research methods will be used: CRS-symptom score questionnaire (SN-5) and Childhood Asthma Control Test (cACT) questionnaires, skin prick test, spirometry, measurement of nitric oxide NO in exhaled breath (FeNO), taste perception test, eosinophil morphology assessment, ratio: glucose concentration in nasal secretion/serum glucose level, concentration of specific immunoglobulin (Ig) E, total immunoglobulin G (IgG) and immunoglobulin A (IgA), the proportion of innate lymphoid cells (ILC) and regulatory lymphocytes cells in the peripheral blood. Endoscopic examination of the upper airways will be performed and samples of the mucosa will be taken. The mucosal examination will be as follows: i) polymerase chain reaction (PCR) examination for the detection of the presence of viral and bacterial genetic material, ii) measurement of the expression of the various messenger ribonucleic acid (mRNA), iii) measurement of the expression of mRNA for the Epithelial-Mesenchymal Transition (EMT) genes and iv) percentage of ILCs.
Read the detailed description
Persistence of CRS and asthma require multiple interconnected feedback and feed-forward circuits between ILCs and epithelial cells. It seems that type 2 ILCs (ILC2) are the most important accelerators of type II immune response that prepare cytokine microenvironment for Th2 cells chronic activation. What decide on ILC2 accumulation - this is an urgent question. The aim of the proposed project is to examine the role of the innate immune response of airways in children suffering from chronic rhinosinusitis and asthma.

What is being measured
The primary outcome is the main question the study is designed to answer.
Asthma Control Test for children (cACT™)
Childhood Asthma Control Test (cACT™), will be used, which has been recommended by the Global Initiative for Asthma (GINA) Report
Measured: 12 months
SN-5
validated questionnaire for the assessment for quality of life in children with CRS (5 symptom-cluster items covering the domains of sinus infection, nasal obstruction, allergy symptoms, emotional distress, and activity limitations)
Measured: 12 months
Secondary outcomes (5)
Spirometry
Respiratory function tests will be performed according to the American Thoracic Society (ATS) standards. The best result of three spirometric maneuvers will be selected for the analysis of obstructive disorders and the level of disease severity according to the standards of the Polish Society of Lung Diseases. The analysis will include FEV1% (A/N% - the percent of the measured to predicted value).
Measured: 12 months
Nasal fraction of exhaled nitric oxide (nFeNO) Measurements
Measurements of nasal fraction of exhaled nitric oxide (nFeNO) will be performed using an electrochemical analyzer (ExpAir) according to the manufacturer's instructions. The detection limit ranged from 1 ppb to 6000 ppb.
Measured: 12 months
Glucose concentration
Glucose concentration in serum and in nasal secretions will be assessed using glucose oxidase sticks (Roche, Lewes, East Sussex, U.K.). Nasal glucose concentration will analyzed in the context of blood glucose level using following ratio: nasal glucose level/blood glucose level.
Measured: 12 months
Immunophenotyping
Mucosa - The nasal mucosa sample will be gently processed (mechanical dissociation, mild enzyme digestion) to produce a single cell suspension. It will be further fixed and stained with specific cocktail of fluorescent dye-stained antibody and then cell identification will be performed by flow cytometry. The relative count of all cell subsets will be determined. All procedures will be performed in buffers containing brefeldin and/or monesin to prevent dislocation of proteins of interest.
Measured: 12 months
quantitative polymerase chain reaction (qPCR)
Total RNA will be isolated from mucosa samples and then reverse-transcribed with e.g. Thermo Scientific Maxima Reverse Transcriptase. qPCR reaction will be performed using house-designed primer sets. Relative expression of genes of interest (involved in innate response) will be analyzed against selected house-keeping gene transcripts.
Manufacturer recommended procedure will be used to quantify Human Epithelial to Mesenchymal Transition gene panel and Multiplex Real-Time PCR for pathogen genes
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Mometasone Nasal in people with Sinusitis and Asthma, run by Medical University of Lodz at 1 site in Poland.
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 3 inclusion and 7 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 13 Aug 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 Poland. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Asthma Control Test for children (cACT™) (time frame: 12 months). The study lists 2 primary outcomes in all. 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 NCT03011632, which also lists 4 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 13 Aug 2019.
