Clinical and cytologic characteristics of allergic rhinitis in elderly patients.

BACKGROUND: The constant increase in the elderly population worldwide has led to a greater interest in immunologic responses during aging. Thus, special attention to allergic diseases in elderly people has begun to emerge, but little is known about the effect and features of allergic rhinitis in elderly people. OBJECTIVE: To evaluate the clinical and cytologic characteristics of respiratory allergy and its impact on the quality of life in elderly people. METHODS: Elderly patients with rhinitis referred to our allergy unit during a 3-month period underwent clinical evaluation and responded to the Rhinasthma Questionnaire. All patients also underwent skin prick testing, measurement of total IgE level, and nasal cytologic analysis. The data were compared with a control group of young adults. RESULTS: Fifty-four patients older than 65 years (mean age, 69.3 years) and 89 young adults (mean age, 26.3 years) with allergic rhinitis were studied. The elderly patients had a less positive family history of atopy (P=.02) and had rhinitis plus conjunctivitis more frequently (P=.002) than young adults, whereas the difference between groups in total IgE level was not statistically significant. On nasal cytologic analysis, the differential count of inflammatory cells did not differ between groups, but in the elderly patients the epithelial-goblet cell ratio was decreased. The quality of life in elderly people was more impaired than in young adults (P=.01). CONCLUSION: In elderly people with allergic rhinitis, the clinical characteristics are different and quality of life is more heavily impaired compared with young adults.

Reversible Cognitive Frailty, Dementia, and All-Cause Mortality. The Italian Longitudinal Study on Aging.

OBJECTIVES: Cognitive frailty, a condition describing the simultaneous presence of physical frailty and mild cognitive impairment, has been recently defined by an international consensus group. We estimated the predictive role of a "reversible" cognitive frailty model on incident dementia, its subtypes, and all-cause mortality in nondemented older individuals. We verified if vascular risk factors or depressive symptoms could modify this predictive role. DESIGN: Longitudinal population-based study with 3.5- and 7-year of median follow-up. SETTING: Eight Italian municipalities included in the Italian Longitudinal Study on Aging. PARTICIPANTS: In 2150 older individuals from the Italian Longitudinal Study on Aging, we operationalized reversible cognitive frailty with the presence of physical frailty and pre-mild cognitive impairment subjective cognitive decline, diagnosed with a self-report measure based on item 14 of the Geriatric Depression Scale. MEASUREMENTS: Incidence of dementia, its subtypes, and all-cause mortality. RESULTS: Over a 3.5-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia [hazard ratio (HR) 2.30, 95% confidence interval (CI) 1.02-5.18], particularly vascular dementia (VaD), and all-cause mortality (HR 1.74, 95% CI 1.07-2.83). Over a 7-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia (HR 2.12, 95% CI 1.12-4.03), particularly VaD, and all-cause mortality (HR 1.39, 95% CI 1.03-2.00). Vascular risk factors and depressive symptoms did not have any effect modifier on the relationship between reversible cognitive frailty and incident dementia and all-cause mortality. CONCLUSIONS: A model of reversible cognitive frailty was a short- and long-term predictor of all-cause mortality and overall dementia, particularly VaD. The absence of vascular risk factors and depressive symptoms did not modify the predictive role of reversible cognitive frailty on these outcomes.
