Study population: Allergic rhinitis (AR) is a common chronic inflammatory disease of the upper respiratory tract with paroxysmal sneezing, nasal congestion, watery nasal discharge and nasal itching as the main clinical symptoms. Bronchial asthma (BA) is a complex heterogeneous chronic inflammatory disease of the bronchi with recurrent symptoms of wheezing, shortness of breath, chest tightness, and coughing.AR usually coexists with BA, and about 70-90% of patients with asthma develop rhinitis, and about 40% of patients with rhinitis develop asthma. When AR and BA occur together, it is called combined allergic rhinitis and asthma syndrome (CARAS).
Who may be able to join
- Patients with AR, BA and CARAS who meet the Western medical diagnostic criteria;
- Chinese medical evidence consistent with lung qi deficiency evidence, phlegm-heat congestion of the lung evidence, or wind-heat offending the lung evidence;
- Age 18 to 80 years;
- Voluntarily accepted the study and signed an informed consent form;
- Not participated in other clinical studies within 1 month before enrollment.
Who cannot join
- Patients with combined vasomotor rhinitis and eosinophilic non-allergic rhinitis, other non-allergic rhinitis diseases that can cause symptoms such as nasal congestion and runny nose;
- Patients who are participating in other drug trials;
- Patients with a combination of other serious systemic diseases;
- Pregnant or lactating women;
- Patients with confusion, disorders of consciousness, dementia, and various psychiatric disorders.

Official title: Preliminary Application and Evaluation of Exhaled Breath Condensate Biomarkers in Combined Allergic Rhinitis and Asthma Syndrome (CARAS)
To explore the differences in the expression of biomarkers in different sample types between the healthy population and different subgroups of the disease, and to screen for potential biomarkers in a more simple, direct and objective way. To screen the biomarkers that can be identified by CARAS Chinese medicine symptoms and different stages, and to provide a reference basis for individualised diagnosis and treatment of the disease.

Measured: Basline
Tumor necrosis factor-β (TNF-β)
Airway inflammation will be assessed using the TNF-β.
Measured: Basline
Eosinophil cationic proteins (ECP)

Measured: Basline
Immunoglobulin E (IgE)

Measured: Basline
Secondary outcomes (5)
Fractional exhaled nitric oxide (FeNO)
Higher FeNO values indicate higher airway inflammation.
Measured: Basline
Forced expiratory volume in one second (FEV1)
Lung function will be assessed using the FEV1.
Measured: Basline
Forced vital capacity (FVC)
Lung function will be assessed using the FEV1.
Measured: Basline
FVC as the percentage of the predicted value (FVC%)
Lung function will be assessed using the FVC%.
Measured: Basline
Forced expiratory volume in one second / forced vital capacity (FEV1/FVC)
Lung function will be assessed using the FEV1/FVC.
Measured: Basline

Questions about this trial
What is this clinical trial studying?
An observational study of Combined Allergic Rhinitis and Asthma Syndrome, run by Henan University of Traditional Chinese Medicine at 1 site in China.
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 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: status not confirmed, as of the sponsor's last update on 28 Aug 2024. 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 China. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Yang Xie (13526621325, xieyanghn@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Interleukin-2、4、5、13 (IL-2、4、5、13) (time frame: Basline). The study lists 5 primary outcomes in all. 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 28 Aug 2024; AzTrials last refreshed its copy on 7 Nov 2026.
