Asthma is characterised by an overload of eosinophils, mast cells, and activated T helper lymphocytes in the airways, resulting in persistent inflammation. The mediators released by these inflammatory cells causes bronchoconstriction, mucus secretion, and remodelling. Cytokines, chemokines, growth factors, lipid mediators, immunoglobulins, and histamine are inflammatory mediators that drive this process. Allergic asthma inflammation can be difficult to manage. The development of adaptive immunity to an allergen, which leads to immunological memory, is the fundamental reason for this. This causes allergic reactions to the allergen to resurface, resulting in chronic inflammation and damage to the airways. Th2 cytokines, which can act as positive feedback loops to encourage the production of more inflammatory mediators, including chemokines and other cytokines, are generally directed by Th2 cytokines in asthma.

Asthma is a widespread disease that affects more than 300 million individuals around the world. Asthma was long thought to be the hallmark T Helper type 2 (TH2) illnesses of the airways, owing to the huge number of eosinophils found in the airways of persons with moderate asthma, as evidenced by findings from murine models. Some neutrophilic inflammation in asthma is now known to be controlled by the TH17 subset of helper T cells, whereas some eosinophilic inflammation is controlled by type 2 Innate Lymphoid cells (ILC2 cells) functioning in concert with basophils.

Asthma is manageable, and it's typically simple to do so. Symptoms should be nonexistent or limited, with little or no need for inhaled 2-agonists to "rescue" the patient. There should be no nocturnal or early morning symptoms, a regular lifestyle, no morbidity, and expiratory flow rates that are normal or close to the patient's best. As a result, there should be little resting bronchoconstriction and little bronchodilator responsiveness. These objectives apply to all levels of asthma severity. Control is achieved with a structured treatment approach that includes patient education, environmental control, and enough anti-inflammatory drugs, as well as an as-needed symptom reliever, typically an inhaled 2-agonist. The need for inhaled 2-agonist should be rare, and it is a semi-objective trait that indicates a lack of control.

Failure to follow asthma recommendations, the presence of a nonresponsive, nonasthmatic illness, and very severe asthma are three reasons why patients with asthma may have inadequate management. Failure to follow asthma treatment guidelines is the most common cause of poor control. Many practitioners may overlook common symptoms as a sign of poor control. This could be due to a lack of acquaintance with current recommendations or a failure to recognise repeated symptoms as an issue. Patients frequently fail to follow suggestions by failing to regulate their environment, use anti-inflammatory drugs, or minimise or recognise the need to reduce their use of bronchodilators.

As inhaled anti-inflammatory medicines are more expensive than bronchodilators, cost is a significant issue in patient noncompliance. The presence of a nonasthmatic disease that does not respond to asthma treatments is a second explanation for poor asthma management. Some of these problems may worsen as a result of asthma treatment. Nonasthmatic airway illnesses include chronic obstructive lung disease, bronchiolitis, and bronchiectasis is among the most frequent. Once coexisting airway disease is ruled out, there are a variety of potential causes for lack of control, including regular or excessive inhaled 2-agonist usage, which can exacerbate asthma management,4 uncontrolled sinusitis, untreated gastroesophageal reflux, and psychogenic issues (psychogenic dyspnea, anxiety-hyperventilation, paradoxical vocal cord function, and factitious asthma).

Exacerbating factors such as 2-agonist overuse, sinusitis, gastric reflux, and psychogenic disorders should be thoroughly investigated in these asthma patients. After excluding them, such people have inadequate control due to the presence of extremely severe asthma. Only in these patients should treatment goals be changed since they are either unattainable or only possible at the expense of unacceptably large corticosteroid doses taken.

Asthma severity has been classified in a number of ways. This can include the severity of overall asthma, the severity of an episode, or the severity of an airflow blockage at a specific period. It's critical to distinguish between the two. Overall asthma severity has traditionally been determined by a combination of symptoms, medication requirements, physiologic abnormalities (reduced flow rates), and morbidity. The majority of these criteria (symptoms, 2-agonist needs, morbidity, and lower flow rates) clearly indicate that asthma control is lacking. The requirement for inhaled anti-inflammatory medication is an exception.

Because severe asthma is a diverse condition, it is still poorly understood and difficult to treat. Patients with severe asthma spend a disproportionate amount of asthma-related health-care resources. Severe asthma can appear gradually or suddenly after the initiation of the condition. The genetic and environmental factors that are most likely to have a role in the development of severe disease are unknown, but they are likely to comprise both allergic and nonallergic factors. Air trapping, airway collapsibility, and a high level of methacholine hyper responsiveness are common physiologic features in these patients. Only recent specific phenotypes of severe asthma have been identified. Severe asthma appears to be divided into two phenotypes that differ at immunologic, physiologic, epidemiologic, and pathologic levels when diagnosed by age of onset (early vs. late).

Patients with severe asthma can also be classified based on the presence and kind of inflammation. Severe asthma with chronic eosinophilia (of early or late start) is more symptomatic and has a higher rate of near-fatal episodes. At least half of people with severe asthma, on the other hand, have very little visible inflammation. As a result, "steroid resistance" can manifest itself in a variety of ways, not all of which are caused by a lack of steroid action on inflammation. Treatment is still difficult, with corticosteroids being the most effective treatment. 5- lipoxygenase inhibitors, anti-IgE, and immunomodulatory medicines, on the other hand, are likely to have a role in treatment. A greater understanding of the phenotypes implicated in this disease will be required to improve therapy.
