Classifying the Severity

         Asthma is considered to be a chronic pulmonary disease that has no cure and is characterized by chronic airway inflammation and bronchial hyper-responsiveness (Dlugasch et al., 2021). In the case of D.R., his symptoms would be classified as step 3: moderate persistent asthma exacerbation. According to the Global Initiative for Asthma (GINA) guidelines (2022), moderate persistent asthma is characterized by daily symptoms, nighttime symptoms more than once a week, peak flow rates consistently at 60-80% of personal best, and exacerbations affecting daily activities. D.R. presents with symptoms lasting several days, nighttime symptoms for three consecutive nights, and peak flow rates ranging from 65-70% of baseline. Additionally, his inadequate response to short-acting beta agonist (SABA) therapy despite prior effectiveness suggests a moderate exacerbation requiring escalation of treatment (Reddel et al., 2022).

Common Asthma Triggers

         Identification of asthma triggers can be complex due to several biological, demographic, behavioral, environmental, and infectious determinates. Asthma exacerbations can be triggered by various factors, including allergens, respiratory infections, irritants, exercise, and weather changes (Zhang & Ram, 2020). In D.R.’s case, his trigger seems to be an infectious process such as a respiratory infection and/or environmental allergens. Respiratory infections, particularly viral infections like the common cold, are well-known triggers for asthma exacerbations (Zhang & Ram, 2020). To support the hypothesis the asthma trigger may be an infectious process and/or environmental allergens, D.R. presents with symptoms consistent with a viral respiratory infection, such as cough, stuffy nose, and watery eyes with postnasal drainage. Furthermore, D.R.’s symptoms of postnasal drainage and watery eyes could also indicate exposure to allergens such as pollen, dust mites, or pet dander which could induce airway inflammation and exacerbate asthma symptoms.

Etiology

         Current evidence suggests that asthma is a complex multifactorial disorder and its etiology is attributed to interactions between genetic susceptibility, host factors, and environmental exposures (Dharmage et al., 2019). Over 100 genes are implicated in the development of asthma and development is thought to be polygenic with multiple genes interacting to then cause the variable phenotype of asthma and in modifying asthma severity and response to treatment (Dlugasch et al., 2021). Host factors contributing to asthma include obesity, nutritional factors, infections, and allergic sensitization exposures (Dharmage et al., 2019). Environmental exposures that could contribute include air pollution, pollens, mold, and other aeroallergens, and weather exposures (Dharmage et al., 2019). Based on the information provided on D.R. the possible etiology of his being an asthmatic patient could be attributed to a genetic predisposition and/or exposure to respiratory infections and allergens.
