About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

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;

Disqualifiers

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;

Trial 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).

Trial outcomes

Primary outcomes

1

Interleukin-2、4、5、13 (IL-2、4、5、13)

Airway inflammation will be assessed using the IL-2、4、5、13.

Time frame
Basline
2

Interferon-γ (IFN-γ)

Airway inflammation will be assessed using the IFN-γ.

Time frame
Basline
3

Tumor necrosis factor-β (TNF-β)

Airway inflammation will be assessed using the TNF-β.

Time frame
Basline
4

Eosinophil cationic proteins (ECP)

Airway inflammation will be assessed using the ECP.

Time frame
Basline

Secondary outcomes

1

Fractional exhaled nitric oxide (FeNO)

Higher FeNO values indicate higher airway inflammation.

Time frame
Basline
2

Forced expiratory volume in one second (FEV1)

Lung function will be assessed using the FEV1.

Time frame
Basline
3

Forced vital capacity (FVC)

Lung function will be assessed using the FEV1.

Time frame
Basline
4

FVC as the percentage of the predicted value (FVC%)

Lung function will be assessed using the FVC%.
