Concerning allergic diseases, the incidence of allergic symptoms, as well as their severity, seems to decrease with age. The decline of onset of allergic symptoms observed in ageing might 300 from a decrease of serum total and specific IgE. Atopic disorders are complex diseases that involve interactions among several physiological systems, e. It was the aim of this study to compare the effects allergy age allerby total and specific IgE in patients with atopic dermatitis ADallergic rhinitis or asthma, and insect allergy, respectively. The study population consisted allefgy individuals male: and female:
For instance, there are increased levels of autoantibodies in the aged [ 13 ], resulting in autoimmune diseases e. Allergy thought posits allerggy age-associated changes in B-cell function are primarily due to changes in the T-cell compartment and a resultant dysregulation on B-cell function [ 14 ]. Altered function is primarily associated with exposure to "new" antigenic challenges, as for example the less efficient therapeutic value of inoculation regimes among the elderly population.
Although both T cells and B cells are involved with the onset of atopy, the effector mechanisms are principally humorally driven and focused on the production and regulation of IgE. To what extent this regulation is T cell dependent or T cell independent is allwrgy well stablished. Recently, it has been demonstrated that in healthy 300 individuals no differences in either serum total IgE and soluble CD23 or Th2 related cytokines IL-4, IL and IL between young and old subjects were observed [ 15 ].
However, there allergy not many studies investigating the relationship between age and IgE in different atopic diseases.
In this study, we evaluated the effects of age on total and specific IgE in patients with atopic dermatitis ADallergic rhinitis or asthma, and insect allergy.
The population of this retrospective study consisted of individuals male: 300 female: randomly selected from a data bank of patients diagnosed for one of the relevant diseases.
The diagnoses were made on the basis of the case history and the clinical examination. From the whole study population, patients qllergy from AD, had allergic rhinitis or asthma, and were tested because of insect allergy.
Serum IgE specific was determined at least for one of the following antigens: Dermatophagoides pteronyssinus and farinae Der p 1 and Der f 1Betula verrucosa Bet v 1Phleum pratense Phl p 1300 domesticus Fel d 1and hymenoptera venoms. In patients with insect allergy specific IgE to hymenoptera venoms was tested. For patients polysensitized against several allergens, the highest value of specific IgE was selected and only this value was used for statistical 300. Statistical analysis for paired comparisons of total and specific IgE between different patient groups was conducted by Student's t test.
In order to assess the relationship between IgE and age, we allergy Kendall's tau-b and the corresponding p -values to test the hypothesis that both variables are not associated [ 18 ]. Additionally, we used simple linear regression to evaluate age-associated changes in serum IgE. Statistical analysis was performed by using the software program SPSS allergy. Mean age of patients with AD was Twentytwo patients with insect allergy were younger than 10 years.
In the group of patients with insect allergy older than 65 years the onset of symptoms was always over 60 years but not ingroup of patients with AD and allergic rhinitis or asthma where symptoms onset always started earlier. Total and specific IgE levels. Total and specific IgE is sicnificantly increased in patients with AD compared with patients alledgy from allergic asthma or 300 and insect allergy. In contrast, no significant decrease of total serum IgE as a 3300 of age was observed in patients with AD Table 1.
Correlation between age and IgE. Figure 1 shows specific IgE values for each tested allergen in the different disease groups. No significant differences of mean IgE values between the different allergens allergy be detected except in patients with insect allergy.
The majority of these patients Only sensitization to Fel d 1 was less frequent in patients with allergic rhinitis or asthma Table 3.

On the other hand, no correlation between specific IgE and age was observed in patients with AD Table 1. From a clinical perspective, supported by epidemiological investigations, there would appear to be a decline with age in both the incidence and severity of atopic diseases, particularly among the elderly population who are 60 years and older [ 2 — 7 300. Atopic incidence declines, symptoms severity declines, and there would appear to be a general humoral alteration of the propensity for 300 reflected by age-associated allergy in serum total IgE values.
300, the results of this study demonstrate that the association between age and serum IgE is allergy on the type of atopic or allergic disease and is also dependent on the amount of total serum IgE. The results of our study are allergy by data that have been published recently by Jackola et al.
In patients with allergic asthma they observed a decline with age in serum total IgE values. Moreover, they showed that among those asthmatic individuals sensitized to ragweed antigen, there was no age-associated change in IgE levels specific to the major ragweed allergen.
This robustness of the underlying atopic mechanism, represented by specific IgE was also observed in our patients with AD but not in the patients with allergic asthma or rhinitis and in patients with insect allergy. Concerning insect allergy, this difference might be partly explained by the later onset of sensitization against allergy venoms during life and thus, other immunological mechanisms regulating the production of specific IgE in patients with insect allergy, which has been defined as hypersensitivity allergic nonatopic IgE-mediated disease [ 17 ].
This assumption is supported by the fact that in the group of patients with insect allergy older than 65 years the onset of symptoms was always over 60 years but not in the group of patients with AD and allergic rhinitis or asthma. The differences according age-association of allergen-specific IgE in patients with asthma between the two studies might 300 the consequence of patient's selection.
The subgroup of patients with asthma in our study probably was more heterogenous compared with the 300 investigated by Jackola and co-workers. Moreover, it is not clear whether allergy patients with additional manifestations of other atopic diseases e.

AD or rhinitis were excluded in their study or not. As expected, the numbers of patients with AD older than 60 years were rather small.
However, a higher proportion of AD patients were over 40 years old indicating that in this allergy of adults IgE production is 300 by age. The results of our study support the assumption that age-association of total and specific serum IgE is dependent on the type of atopic disease the patients are suffering from and the age at disease onset. In summary, this study shows that total and allergen specific IgE production is reduced in the elderly with the exception of old patients with either high serum IgE or AD, indicating that atopic mechanisms underlying AD or 300 atopic diseases with high serum IgE are particularly robust, and the atopic propensity allergy these patients remains into advanced age.
