Purpose: Chronic rhinosinusitis (CRS) is one of the most common chronic diseases in the geriatric population. However, CRS inflammatory mechanisms in older people have not been thoroughly investigated. Our work aimed to analyze the bacterial flora of the nose and paranasal sinuses in patients with CRS over 65 years of age, including comorbidities, previously performed endoscopic sinus surgery (ESS), presence or absence of polyps and the extent of the inflammatory process.
Patients and Methods: The study involved 529 patients between 18 and 84 years of age with chronic rhinosinusitis who underwent endoscopic sinus surgery. There were 101 patients separated over 65 years of age (M = 52, K = 49, mean age 69 ± 0.7 years). The control group consisted of 168 patients aged 18– 40 years with CRS. The bacterial culture of material collected from the patients during ESS was analyzed.
Results: In the group of patients over 65 years of age, more frequent occurrence of Proteus spp. and Pseudomonas aeruginosa was found in comparison to younger patients. In older patients with bronchial asthma, the occurrence of S. aureus, Escherichia coli, and Citrobacter spp. was more frequent than in control group. Multiple sinus surgical procedures in older patients were associated with the dominance of Staphylococcus aureus and Escherichia coli, which was not demonstrated in the control group. There were no statistically significant differences between the occurrence of bacterial strain and the presence of polyps, both in the group of patients over 65 years of age as well as in the control group.
Conclusion: The bacterial flora of patients with CRS is different in older and younger patients. A different therapeutic approach should be considered in older patients with CRS, but this problem requires further studies.
