“…The frequency of rhinitis in the elderly has been addressed in very few elderly-targeted studies. Ventura et al (17) found that rhinitis was present in 16.8% of the patients aged over 65 years referred to an allergology unit. Population-based studies are even scarcer.…”

Background: Nationwide epidemiologic data on rhinitis in the elderly do not exist. This study aimed to estimate the prevalence of rhinitis in the population aged 65 years or above in mainland Portugal and to characterize and classify rhinitis in this age group. Methods: Cross-sectional, nationwide, population-based survey of citizens aged 65 years or above, living in mainland Portugal. Current rhinitis (CR) was defined as the presence of at least two symptoms: 'repeated sneezing and itchy nose', 'blocked nose for more than one whole hour', or 'runny nose when not having a cold or flu', either usually or in the last 12 months.Rhinitis severity was assessed using a visual analogue scale; rhinitis was classified according to ARIA. Results: Data were obtained from 3678 responders (92.5% response rate). The prevalence of CR was 29.8% (95% confidence interval (CI): 28.4%-31.3%): 49.1% had mild intermittent, 7.0% mild persistent, 27.5% moderate-severe intermittent, and 16.4% moderate-severe persistent rhinitis. Only 38.6% of patients with CR had been physician diagnosed and 38.7% were under treatment for this disease in the previous year. Allergic conjunctivitis symptoms were referred by 68.6% of subjects with CR (rhinoconjunctivitis population prevalence, 20.5% (95% CI: 19.2%-21.8%)). Conclusions: Rhinitis and rhinoconjunctivitis are common but underdiagnosed and undertreated diseases in the geriatric population. This was the first nationwide epidemiological survey classifying rhinitis according to ARIA guidelines in this age group. More than 40% of old-age patients presented moderate-severe disease.

“…It is a matter of debate how much structural as well as functional changes of the mucosa and skin, in addition to immunological alterations affecting, for example, lymphocytes and lymphokines, encountered at old age are responsible for these figures [21][22][23] . Adverse reactions to food may differ in their pathophysiology encompassing both allergic and non-allergic hypersensitivity reactions [9] .…”

Food Allergy: An Increasing Problem for the Elderly

As populations become older all over the world, allergic reactions in elderly persons will be encountered more often in the future. Up to now, there has been much more literature on allergy prevalence in childhood than on allergy diseases in adults. As a challenge to epidemiology, allergic disorders in elderly persons may be masked by various symptoms corresponding with a general age-induced decline of physiological functions, including vitamin D deficiency and gastric pH increase. How much structural and functional changes (e.g. low calcitriol level) or effects caused by drugs (e.g. acid-suppression medications) in addition to immunological alterations encountered at old age are responsible for this development is a matter of debate. In the years ahead, the problem of allergy in adulthood and especially in the elderly will become more pronounced.

“…Em relação à idade, existem poucos trabalhos abordando os quadros alérgicos em idosos [16][17][18][19][20][21][22][23][24][25][26][27][28][29], sendo que dois estudos nacionais apontaram uma alta prevalência de manifestações cutâneas nessa faixa etária, entre as quais a DC [21] e o prurido, como sintoma isolado [22].…”

Resultados: Foram incluídos 362 pacientes, entre o quais 60 idosos (idade maior ou igual a 60 anos) e 302 não idosos. Além da dermatite de contato foram observados outros tipos de alergias em 20 (33,3%) dos idosos e em 113 (37,4%) dos não idosos (p=0,54). Houve um total de 162 reações positivas ao patch test entre os idosos e 738 reações positivas entre os não idosos (p=0,24). Quanto às reações positivas fortes ocorreram 41 (68,3%) entre os idosos e 156 (51,6%) entre os não idosos (p=0,02). Somando-se reações positivas fortes e muito fortes, foram 44 (73,3%) em idosos e 214 (70,8%) em não idosos (p=0,69). As substâncias mais sensibilizantes foram o sulfato de níquel (em 33,3% dos idosos e 38 % dos não idosos) e o perfume mix (em 25% dos idosos e 27,8% dos não idosos), sem diferença estatística entre os dois grupos etários. Conclusões: A taxa de positividade do patch test entre os pacientes com dermatite de contato foi alta, não havendo diferença entre idosos e não idosos, sendo o sulfato de níquel e o perfume mix as substâncias mais sensibilizantes. Na investigação etiológica da dermatite de contato deve-se pensar principalmente na possibilidade de sensibilização aos perfumes e ao níquel, independentemente da faixa etária. DESCRITORES: dermatite de contato; idoso; perfumes; níquel; testes do emplastro. ABSTRACT Aims:To evaluate the prevalence of the main allergens found in allergic contact dermatitis among elderly and non-elderly patients. Methods: Retrospective study of the medical records of patients clinically diagnosed with contact dermatitis treated from August 2000 to January 2012 at the Allergy Outpatient Clinic of Marília Medical School and at an Allergy and Dermatology private clinic in Marília, state of São Paulo, Brazil. The inclusion criteria were clinical diagnosis of contact dermatitis, patch test performed during the study period, and no treatment with systemic corticosteroids or any other immunosuppressants. Age, sex, history of other types of allergy and allergens used were assessed. The patch test results were read 48 hours and 72 hours after application of the test chambers. Results: A total of 362 patients were included in the study: 60 elderly patients (aged 60 years or older) and 302 non-elderly patients. In addition to contact dermatitis, other types of allergies were observed in 20 (33.3%) of elderly patients and in 113 (37.4%) of non-elderly patients (p=0.54). There were 162 positive reactions on the patch test among elderly patients and 738 positive reactions among non-elderly patients (p=0.24). Strong positive reactions were present in 41 (68.3%) elderly patients and in 156 (51.6%) non-elderly patients (p=0.02). Strong and very strong positive reactions, when assessed together, were detected in 44 (73.3%) elderly patients and in 214 (70.8%) non-elderly patient...
