Abstract: 

Rationale

For a long time, allergy was not considered to play an important role in respiratory symptoms in elderly. This concept has been reassessed recently. The aim of this study is to describe the profile of sensitization to inhalant allergens (AI) in elderly patients with respiratory allergy symptoms.

 

Methods

Retrospective analysis of medical records of patients older than 60 years assisted in Allergic Clinic of Policlinica Geral of Rio de Janeiro and diagnosed with asthma or rhinitis. They performed skin prick test (SPT) for aeroallergens, according to the Task Force Practice Parameters 1995, from August 2010 to August 2013.

 

Results

A total of 135 patients with a mean age of 68.9 years were evlauted: 98 female (72.6%). All but one patient presented rhinitis symptoms (99.3%) and 37 (27.4%) had rhinitis and asthma associated. Regarding SPT, 62.2% were positive for D. pteronyssinus, 52.6% for D. farinae, 45.2% for B. tropicalis, 15.6% for fungi mix, 12.6% for dog, 14.8% to cat, 8.1% for A. fumigatus, 32.6% for cockroach and 6.7% to grass pollen. SPT was negative in only 9.5% of the patients. There was no statistically significant difference between the frequency of sensitization to each allergen and the age or gender of the sample.

 

Conclusions

The frequency of sensitization to inhalant allergens was as high as in younger age groups, as like as the profile. The allergic etiology should always be investigated in elderly patients with respiratory symptoms suggestive of atopy.
