Cough Variant Asthma, CVA is a special type of asthma, mainly reflected in cough, while asthma symptoms are lighter or less. The following is a detailed description of the treatment of cough variant asthma:
I. Diagnosis
1. Clinical symptoms: The main symptoms are irritating dry cough, which is usually more severe and is an important feature of night cough. Coughs are usually sustained or repeated, often accompanied by sexual coughing at night or in the morning, which increases after the exercise. Some of the patients may be associated with dysentery, breathing, dysentery, but relatively light.
2. Auxiliary examination: lung function examination: Aerodynamic high-reactivity is an important basis for the diagnosis of cough variant asthma. Bneumatic bronchial stimulation test: Positive results suggest a high-reactive gas route that facilitates diagnosis. Exhalation peak (PEF): an average day and night variability rate of >10%, or PEF weekly variability rate of >20%, may be used as a basis for supporting diagnosis. Allergen testing: the identification of allergens contributes to prevention and treatment. Breast X-ray or CT: There is usually no apparent anomaly, but it can be used to exclude other lung diseases.
3. Diagnostic criteria: Chronic cough, often accompanied by sexual cough at night or in the morning, aggravated after exercise. Bneumatic tubes stimulate test positive or pneumatic peak (PEF) > 10% day and night variability. bronchial extension treatment is effective. Exclude other diseases that cause chronic cough, such as chronic bronchitis, bronchial expansion, etc.
Treatment
General treatment
Avoiding triggers: Identify and minimize exposure to allergies or other irritations that may trigger asthma symptoms, such as pollen, dust mites, animal fur, smoke, etc.
Lifestyle adaptation: Maintaining good living habits, including adequate sleep, balanced diet and moderate sports. (c) Avoiding intense physical activity, as some patients may experience increased post-motion symptoms.
Environmental Control: Keep indoor air clean, regularly clean home environments and reduce the growth of dust mites and other allergens.
2. Drug treatment
Inhalation of sugar cortex hormones: this is the main drug for the treatment of cough mutinous asthma, which mitigates the symptoms of cough through local inflammation. The most common drugs are Boudinaid, Fluidacason, etc.
Long-acting β2 receptor agonists: This drug can relax the airway smoothing muscles and reduce the narrow air lanes, thus mitigating cough and asthma symptoms. The usual drugs are salmetero and so on.
Ditrilene regulater: Cough symptoms are mitigated by regulating the biological activity of triolene, reducing gas tract inflammation and swelling. The most common drugs are sodium Monust.
Anti-sensitization drugs: Anti-sensitization drugs, such as ketphene, thitriazine, etc., can be used as appropriate for cough-modified asthma patients with allergies.
Coughing drugs: coughing drugs can be used to mitigate cough symptoms if necessary, but care is taken to avoid overuse and cover-up or side effects.
Other treatments
Medical Chinese medicine: According to Chinese medicine, cough mutated asthma may be associated with pulmonary spleen and kidney disorders. Thus, the pulmonary spleen and kidney function can be regulated by Chinese medicine for the purpose of coughing. The usual Chinese prescriptions are small cyanide soup, chowder soup, etc.
Immunotherapy: For patients who are known to be allergic, special immunotherapy (dissensitization treatment) can be considered to reduce cough symptoms by gradually increasing the patient ‘ s tolerance to the sensitizer by injecting under the skin or having an allergy under the tongue.
bronchial thermoformation: This is a surgical treatment for severe asthma, which reduces cough symptoms by reducing the number of airway smoothing muscles and reducing their high responsiveness. However, the method is mainly used to treat typical asthma and its applicability to cough variants needs further study.
III. PREPARED AND PREVENTION
1. Prognosis: Cough mutated asthma is treated in a standard way, and most patients have good control and symptoms are reduced or disappeared. However, some patients may experience repeated episodes due to the persistence of allergies or inadequate treatment, and progress is typical of asthma.
2. Prevention: Avoiding exposure to allergens and conducting regular sensitization tests. Keep indoor air clean and avoid smoking and passive smoking. Increased exercise and increased body immunity. Pulmonary function checks are conducted regularly to detect and treat lung diseases in a timely manner.
In conclusion, the diagnosis and treatment of cough mutated asthma requires a combination of clinical symptoms of the patient, the results of the secondary examinations and individual differences. Standardized treatment and effective preventive measures are important in controlling conditions, reducing symptoms and improving the quality of life.
