Asthma Classification

Depending on the factors causing exacerbation, asthma is divided into different clinical forms: allergic, nutritional (food), Aspirin-sensitive, infective, and steroid-dependent and exercise induced asthma.


Allergic (atopic) asthma. Rhinitis, conjunctivitis and bronchismus combination are typical symptoms. Blood tests show increase of IgE levels. Often it is accompanied with lingering exacerbations. Genetic predisposition to allergic diseases can be observed. It may show itself as an epidemic attack.

Nutritional asthma. Caused by some food products. Asthma attack begins after 8-12 hours after meal, due to this fact the patients are rarely able to relate asthma attacks to a certain product. Medical history often has references to other allergic diseases which usually occur under the influence of dietary factors (exudative diathesis, urticaria fever, atopic dermatitis).

Aspirin-sensitive asthma. Characterized by a complex of symptoms: nasal polyp, rhinitis, nonsteroidal anti-inflammatory drugs intolerance. Their intake causes asthma attack. Polyps can also be localized in gastrointestinal and urogenital tracts. It manifests with severe course. The death rate reaches 10%, due to sudden anaphylactoid reactions after taking NSAIDs or food with high salicylate concentration. Read for getting more information –

Infective asthma. Has a rich variety of clinical signs. As a rule, it is characterized by severe course, can cause disablement.

Exercise induced asthma. In most cases appears at young ages. Asthma attacks are caused by brisk walking, running, laughing, fear and other physical exercise or emotion. Asthma attack does not occur at the moment of procatarxis impact, but at the rest state (5-10 minutes later).

Bronchial Asthma Pathogenesis

According to the modern concept asthma has inflammatory nature. Inflammation can be induced by contact with allergen, industrial pollutions or acute viral infection. It is Considered to be continuous, regardless of its severity.

Genetic factor plays a special role in the disease development. People with genetic predisposition the disease appears at early childhood and has more severe course. Exacerbations may be triggered by a wider allergens variety and other factors.

The disease manifestation is influenced by:

  • age;
  • airborne allergen;
  • industrial air pollution;
  • weather conditions;
  • previous respiratory tract infections (especially viral);
  • psychoemotional factors.

Asthma Clinical Characteristics

Bronchial asthma clinical characteristics has diversity and include pathologic process of not only respiratory tract but also the skin cover, gastrointestinal tract, psychoemotional spheres, blood-forming and visual organs.

The frequency of occurrence and symptom load widely vary and depend on the degree of airway obstruction, type and course of the disease. There are two basic variants of bronchial asthma that can be distinguished:

  • intermittent – characterized by long-lasting remission (attack-free intervals), sometimes lasting for decades;
  • persistent – characterized by continuous exacerbations, inability of sustained remission.


Asthma Symptoms

During remission period patients with uncomplicated asthma course don’t usually suffer from symptoms and signs. Some patients on intense exhale or after physical exercise have dry mono wheezes and sibilant rales.

Acute asthma course is characterized by the following symptoms:

  • dyspnoea;
  • non-productive cough;
  • sibilant rales;
  • chest tightness and shortness of breath.

Different combination of these symptoms are possible. Asthma attacks result in discharge of pituita, bringing relief to the patient.

Exacerbations usually occur because of undertreatment or contact with risk factor. Asthma attacks appear more often in the morning or at night, may be triggered by risk factors. Usually recrudescence increases during several hours or days, sometimes – during few minutes. You may find more facts about symptoms of asthma in special category –

General Principles of Bronchial Asthma Treatment

Asthma treatment pursues following objectives:

  1. chronic and unpleasant symptoms prevention(e. g. cough and apneusis at night, early in the morning or after physical exercise);
  2. maintaining a (near) «normal» pulmonary function;
  3. maintaining normal activity level (including exercise and other physical activities);
  4. preventing further recrudescence and minimizing necessity of calling ambulance and emergency hospitalization;
  5. maintaining optimal drug therapy with minimal number of side effects, or complete lack thereof (Many pharmacies today, e. g. Canadian Health&Care Mall, offer a wide range of the latest drugs that cause minimal side affects online);
  6. satisfying patients and their relatives with the results of treatment.

The absence of clinical signs of the disease does not except current respiratory tract inflammatory process, so the basic anti-inflammatory therapy should be carried out regardless of asthma clinical aspects severity.
