ABSTRACT
ObjectiveThis observational case-control study analyzed the clinical, functional, inflammatory profile, and treatment data of a cohort of patients with asthma who were followed up at the outpatient clinic of a teaching hospital.MethodsPatients who visited the clinic between January 2008 and February 2020 and diagnosed with asthma according to the Global Initiative for Asthma (GINA) criteria were included in the study. Patients were broadly classified into two groups age <60 or age ≥60 years. The patients were evaluated for asthma control and severity, medications used, comorbidities, smoking status, occurrence of exacerbation, spirometry at the first and last visits, sputum cytology, allergic prick test, and inflammatory cytokine levels.ResultsPatients over 60 years of age had lower asthma control test (ACT) scores, required higher doses of inhaled corticosteroids to achieve asthma control and had worse lung function with fixed airway obstruction, higher number of comorbidities, greater exposure to tobacco, and longer outpatient follow-up than younger patients with asthma. Furthermore, older patients presented with neutrophilia and higher levels of TNFα in the induced sputum as compared to younger patients.ConclusionsThese findings suggest that patients aged ≥60 years of age had a more severe asthma profile and poorer lung function than younger patients with asthma. Furthermore, aging, long-term asthma, comorbidities, and tobacco exposure contributed to an accelerated decline in lung function.
