Can Self-Efficacy Improve Your Asthma Symptoms?
What is Asthma?
Asthma is an airway disease that manifests through chronic inflammation. The airway hyperresponsiveness in asthma patients occurs under the impact of various triggers including exercise, allergens, and viruses (Quirt et al., 2018). The airspace narrowing leads to the development of respiratory symptoms including coughing, chest tightness, breathlessness/shortness of breath, and wheezing. The reversibility of airflow obstruction in asthma patients is either spontaneous or based on the administration of fast-acting bronchodilators. Asthma exacerbation progresses through acute wheezes that lead to life-threatening respiratory complications if left untreated. Asthma of childhood often associates with hay fever, eczema, or atopy. Asthma not only elevates health care costs but also increases the risk of multiple hospital admissions (Hashmi, Tariq, & Cataletto, 2020).
What are the Various Types of Asthma?
Asthma is categorized into the following
phenotypes.
1. Severe asthma
2. Asthma in aged/elderly people

What Causes Asthma?
The below-mentioned outdoor and indoor
pollutants/allergens elevate the risk of asthma in predisposed or high-risk
individuals (Chabra & Gupta, 2020).
1. Waste materials from combustion devices
2. High ozone levels
3. Fumes containing various pollutants
4. Irritant chemicals
5. Smoking
6. Smog
7. Biological allergens, including mold, animal
dander, cockroaches, and dust mites
8. Excessive physical activity or exercise
9. Humidity
10. Temperature changes
11. Flu, cold, sinusitis, and other respiratory
infections
12. Pollens and spores
What is the Pathophysiology of Asthma?
The reversible respiratory manifestations of asthma
rely on the following pathophysiological mechanisms (Hashmi, Tariq, &
Cataletto, 2020) (Bush, 2019).
1. Elevation in airway mucus/inflammation due to
bronchial hypersensitivity
2. A remarkable elevation in airway resistance
3. Smooth muscle contraction
4. Mucus plug formation and hypersecretion
5. Inflammatory cell infiltration
The irreversible asthma complications reciprocate
with the development of the following conditions.
1. Epithelial desquamation
2. Collagen deposition
3. Basement membrane thickening
4. Smooth muscle hyperplasia/hypertrophy
5. Airway remodeling
6. Impaired lung growth trajectories
The asthma progression mechanism is based on the
following processes (Sinyor & Perez, 2020).
1. The early phase of asthma
exacerbation begins with the triggering of plasma cell-based IgE
antibodies.
2. The accumulation of IgE antibodies in asthma
patients occurs under the influence of environmental triggers and genetic
factors.
3. The basophils and mast cells effectively bind with
IgE antibodies.
4. The exposure of asthma patients to various
environmental triggers or pollutants leads to the degranulation of mast
cells.
5. The mast cells eventually release cytokines,
leukotrienes, prostaglandins, and histamine.
6. The release of toxicities under the influence of
environmental triggers leads to airway tightening based on smooth muscle
contraction.
7. The production of GM-CSF and interleukins (IL-13,
IL-5, and IL-4) occurs under the impact of Th2 lymphocytes that eventually
leads to respiratory passage inflammation.
8. The survival of basophils and eosinophils occurs
under the impact of IL-5 and IL-3.
9. The development of hyperplasia, fibrosis, and
remodeling occurs under the influence of IL-13.
10. The late phase of asthma exacerbation
manifests through the localization of memory T-cells, helper cells,
neutrophils, basophils, and eosinophils across the lung surface, thereby
leading to inflammation and bronchoconstriction.
11. The transport of late-phase reactants to the
inflamed locations occurs under the impact of mast cells.
12. The intensity of airway inflammation and
bronchoconstriction determines asthma severity.
13. The narrowing and thickness of airways determine
the overall asthma duration.
14. The increased breathing work reciprocates with
intermittent flow obstruction.
15. The exaggerated bronchoconstrictor responses to
various environmental triggers lead to airway hyperresponsiveness in asthma
patients.
16. The respiratory manifestations of asthma progress
under the influence of elevated airway smooth muscle mass and histamine
production (from mast cells).
17. The increased contractility of airway smooth muscle
cells occurs under the influence of intracellular free calcium elevation and
vagal tone.
18. The extent of lung function decline determines the
intensity of asthma exacerbation.
19. The breathing difficulty of asthma patients
increases under the impact of bronchiolar mucus, exudate, granular white blood
cell accumulation, and airway inflammation.
20. The collagen deposition in airways occurs due to
increased myofibroblasts that lead to epithelium elevation and narrowing of
lamina reticularis/smooth muscle layer.
21. The basement membrane thickening could lead to
irreversible airflow obstruction under the impact of airway remodeling.
What are the Diagnostic Approaches for Asthma
Evaluation?
The following clinical methods assist in diagnosing
asthma and its complications (Saglani & Menzie-Gow, 2019) (Lab Tests
Online, 2020).
1. The elevated fraction of nitric oxide in exhaled
air indicates a marked increase in eosinophilic-mediated airway
inflammation.
2. The complete physical examination and review of
symptoms are paramount to the assessment of asthma signs and symptoms.
3. The assessment of blood eosinophil count helps in
diagnosing asthma among children. Eosinophilia in children is indicated by the
eosinophil count of greater than 500.
4. Spirometry assists in evaluating pulmonary function
based on FEV1 (Forced Expiratory Volume in One Second). FEV1/FVC value of less
than seventy-percent indicates airflow obstruction.
5. A chest x-ray helps to rule out structural and
functional abnormalities in the lungs.
6. IgE assessment also helps to evaluate asthma
development.
7. Sputum culture helps in ruling out pulmonary
infections.
8. Sputum cytology helps to determine the extent of
airway inflammation.
9. The organ function assessment of asthma patients
relies on a comprehensive metabolic panel.
10. Complete Blood Count (CBC) helps to evaluate inflammation
and infection in asthma patients.
11. The assessment of arterial blood gases helps to
evaluate the levels of carbon dioxide, oxygen, and blood pH.
12. Allergic sensitivity testing helps to evaluate the
impact of asthma triggers, including pollens, pet dander, mold, mites, and
dust.
The Asthma Control Cycle
Evidence-based clinical literature documents the
following asthma control measures based on the review of symptoms/lung
function, diagnostic assessment, and medication adjustment (Horak et al.,
2016).
1. The asthma review process relies on the systematic
evaluation of symptoms, respiratory exacerbation patterns, medication side
effects, patient satisfaction, and lung function.
2. The assessment is based on the meaningful
evaluation of asthma diagnosis, risk factors, medication inhalation compliance,
and patient preference.
3. The adjustment of asthma medications,
non-pharmacological interventions, and modifiable risk factors is highly
necessary to reduce the frequency of asthma attacks.
4. Inhalation therapy is the first-line treatment for
asthma management. This treatment method is increasingly used by asthma
patients based on high tolerance and limited side effects.
5. The regular intake of controller medication not
only minimizes inflammation and respiratory symptoms but also reduces the risk
of exacerbations.
6. The controller medications include methylxanthines,
long-acting anticholinergics, leukotriene receptor agonists, long-acting
beta-2-agonists, and inhaled corticosteroids.
7. The reliever medications include short-acting
anticholinergics and short-acting beta-2 agonists.
8. Add-on therapy includes phenotype-oriented
medications, anti-IL5 therapy, oral/systemic corticosteroids, and anti-IgE
therapy.
What are the Non-Pharmacological Asthma Management
Options?
You may opt from the following list of physical
activities and dietary interventions for managing your asthma exacerbations.
However, the careful selection of the prevention strategies undoubtedly
warrants medical supervision.
1. Water-based activities
2. Swimming
3. Inspiratory muscles training
4. Breathing exercises
5. Physical activity
6. Vitamin E/C Supplementation
7. Selenium-enriched diet
8. A diet based on marine fatty acid
9. A diet with reduced monosodium glutamate
10. Low-salt diet
11. Elevated caffeine intake
What is the Role of Self-Efficacy in Asthma
Improvement?
Self-efficacy improvement is the preliminary
requirement for the systematic management of asthma symptoms (Mancuso, Sayles,
& Allegrante, 2010). Greater awareness of asthma causes, pathophysiology,
treatment requirements, compliance measures, medication dosages, and
therapeutic outcomes potentially assists asthma patients to effectively control
their respiratory complications. An improved self-efficacy not only reduces
asthma exacerbations but also helps to prevent asthma-related comorbidities.
Some of the tested self-efficacy improvement measures for asthma patients are
listed below.
1. Increased socialization is the need of the hour for
reducing the risk of asthma-related depression.
2. Asthma patients need to improve their knowledge of
environmental triggers that cause respiratory exacerbations. They must take
necessary dietary precautions, physical activity measures, and other safeguards
for reducing their health adversities based on weather variations, pollution,
upper respiratory infections, allergies, and stress.
3. The thorough knowledge of asthma medications and
their adverse effects is highly needed to reduce the frequency of asthma
attacks. The asthma patients require managing the appropriate stack of
medicines and carry the steroid inhalers to manage their respiratory
stress.
4. Asthma patients need to improve their knowledge of
their perceived health care outcomes.
5. The acquisition of regular feedback from physicians
and caretakers also proves helpful in managing the stressful complications of
asthma exacerbations.
