Abstract
Co-morbidities are a significant problem in the elderly population but are rarely presented and analyzed for interdependencies among the various coexisting chronic diseases. Objective: The aim of this study was to present a profile of comorbidities in elderly patients with and without asthma and COPD. Methods: Respondents were recruited at 20 sites in Poland. Stratified random sampling from patient databases resulted in 15,973 patients older than 60 years of age. A retrospective analysis of medical history and ICD-10 codes was performed. In addition, patients underwent a spirometry test with a bronchial reversibility test and were administered questionnaires on the prevalence of chronic diseases by doctors. Results: The study population consisted of 1023 asthmatic patients, 1084 patients with COPD and 1076 control subjects without any signs of bronchoconstriction and with correct spirometry. Patients with asthma exhibited a similar distribution of cardiovascular and metabolic co-morbidities as the control group. However, asthmatic patients had a higher prevalence of arterial hypertension and depression with an odds ratio (OR) = 1.48 (95% CI: 1.38–1.62) and OR = 1.52 (95% CI: 1.44–1.68), respectively. Coronary disease (OR = 2.12; 95% CI: 1.97–2.33), cor pulmonale (OR = 3.1; 95% CI: 2.87–3.22) and heart failure (OR = 2.71; 95% CI: 2.64–3.11) were predominantly observed in patients with COPD. Patients with severe asthma exhibited a greater predisposition to cardiovascular and neuropsychiatric diseases. Conclusion: Asthma coexisted frequently with arterial hypertension and depression in elderly patients. Patients with COPD have a more exaggerated profile of coexisting diseases, specifically cardiovascular problems.
