Although it has reached the early spring stage, the temperature in the north still fluctuates significantly, and allergic cough is still in the high incidence stage. A lot of people are always coughing and coughing and recurring.
Allergic cough can occur at any age and has recurrent or persistent coughs for more than a month. The onset is not limited to winter and spring, and is more common at night and in the morning, and cough is worse during exercise.
Symptoms of allergic cough
Dry cough with less phlegm
The main clinical symptom of allergic cough is dry cough, there will be phlegm in the throat, but it is very little, and the cough has the characteristics of frequent and paroxysmal attacks at night, and after getting up in the morning, it is generally relieved by a few slight coughs, but in severe cases, coughing and wheezing and wheezing symptoms can appear.
Respiratory symptoms
It may be accompanied by some respiratory symptoms, such as coarse breath sounds and snoring during sleep, as well as mild nasal congestion and sneezing due to respiratory infections. In addition, only a very small percentage of patients** develop an erythematous rash and may be complicated by atopic dermatitis.
The key point of allergic cough
Standardized diagnostics
standardized diagnosis
By carefulTake a medical history(Duration of cough, circadian pattern, nature, predisposing factors, accompanying symptoms, etc.) and corresponding laboratory tests, narrow the scope of diagnosis of cough, provide the best diagnostic clues, obtain preliminary diagnostic results and perform the following examinations to confirm the diagnosis.
1. Chest X-ray or CT examination
Usually normal or with increased lung markings but no other organic lesions.
2. Pulmonary function test
Bronchial provocation testing is indicated when the patient's forced expiratory volume in one second (FEV1) is greater than 70% of the predicted value. Bronchial provocation tests in patients with allergic cough are generally negative, and a positive test indicates airway hyperreactivity and is an important basis for clinical diagnosis of cough-variant asthma.
3. Exhaled nitric oxide (FENO) level measurement
FENO assay is a recognized non-invasive test method for the assessment of airway inflammation, which has the characteristics of quantifiable, simple, safe, real-time, reproducible, etc., and has high sensitivity and specificity. It is mainly used for the diagnosis, differential diagnosis and differential diagnosis of common airway inflammatory diseases such as allergic cough, chronic cough, asthma, and chronic obstructive pulmonary disease
The FENO assay can be rapid
Get tested for allergic cough
Nitric oxide levels in the airways are measured by breathing in and intake, eliminating the need for a painful examination process. In allergic cough, inflammation of the airways may lead to elevated nitric oxide levels. Combined with clinical information, it helps doctors better understand the patient's condition and thus more accurately diagnose allergic cough or other respiratory diseases. Monitor the effectiveness of the program to ensure the adjustment and optimization of the program.
4. Allergen detection
Allergen testing is indicated in patients with suspected anaphylactic cough to identify the allergen as early as possible.
Effective**
effective treatment
1. Remove allergens: stay away from or avoid contact with allergens, and take desensitization if necessary*** can effectively prevent allergic cough.
2. Drugs**: antitussive drugs, glucocorticoids, and antihistamines are the mainstays.
Life advice
life advice
During the remission period of allergic cough, it is necessary to actively prevent acute attacks, strengthen self-immunity, and increase or decrease clothing in time according to the temperature changes of the weather to avoid colds and avoid inducing cough attacks.
