Food allergy in Alergológica

To measure the frequency and to determine the characteristics of Hymenoptera hypersensitivity in a Spanish population at a particular point in time and compare with the data obtained in a similar study carried out in The number of patients included in the study alergoloticaof whom 77 1. This represented an increase of 0.

The honey bee was responsible for The group with Hymenoptera allergy had a predominance of males This population needed assistance in emergency units and hospitalisation more frequently. They had a low score on the mental component of the quality of life questionnaire.

Asthma in Alergológica-2005.

The typical patient profile is of a man, living in a small village, working outdoors with significant exposure to alerrgologica stings and in contact with farm animals, without atopic diseases. Bees and wasps are equally responsible of the stings.

The need of emergency assistance in those patients is higher and the waiting time to be attended by an allergist is shorter. Abejas y avispas fueron igualmente responsables de las picaduras.

However, allergic hypersensitivity [19]. Inour Society repeated this observational, can result in more severe local reactions or generalized prospective, and cross-sectional study on a sample of systemic reactions. Just one insect sting may provoke a subjects seen in allergic clinics and selected at their first severe allergic reaction, which can be furthermore fatal, in a interview.

The prevalence of Hymenoptera venom allergy previously sensitized person [1]. Particularly, Hymenoptera and the influence of several risk factors in its development are the insects that cause the most frequent, relevant and were also evaluated, and compared with the data obtained dangerous reactions.

The allergic reaction may be caused by more than ten years before [20]. This trial was carried out by stings from a number of species in this insect order, occurring allergists from every part of Spain throughout two selected only in individuals who have previously been sensitized to periods of The subjects were asked specific questions Hymenoptera venom.

Systemic reactions also are IgE mediated population data of our recent trial. Material and Methods Insect sting allergy may develop at any age, and usually manifests after several uneventful stings []. It is known An observational, prospective and cross-sectional study that strong local reactions are more frequent than systemic was carried out on a sample of subjects.

The aim of the reactions, and range from 2. All the data on the methods used are described previously Systemic reactions among beekeepers are more frequent, and fall [21]. Compared with adults, children have a higher frequency differences between qualitative variables were described using of isolated cutaneous reactions to insect stings and a lower the chi-square test and the comparison of the average values frequency of vascular symptoms and anaphylactic shock.


However, it is very important to recognize both the cases were bee-keepers or their family members. Eighteen patients had suffered more exposure will influence the risk of receiving a sting. Certain than one sting reaction during the previous year.

Sixty-one of the 77 cases had suffered, their family membersgreenhouse workers, food handlers, previously to the present reaction, reactions with Hymenoptera bakers.

Beehives or wasp nests located in the vicinity of stings: Systemic allergic reactions to Hymenoptera stings are Twenty-five cases were admitted to the emergency estimated to occur in about 2. In department and were treated with epinephrine; three 8. Type of Reaction of cases. The waiting list to be attended was lower in patients with Hymenoptera allergy. The median of days necessary to reach a diagnosis was This fact revealed a significant difference Grade 1 11 Grade 2 22 The explanation for this Grade 4 8 It should be noted that Immunotherapy Discussion was prescribed in The schedules of immunotherapy used were conventional in There is asymptomatic sensitization the cases, rhinitis in 5.

If we compare these data with those obtained from the The diagnostic tests used in the study of these patients were sample, we can easily conclude that there is a misdiagnosis of clinical histories, skin tests and quantification of specific IgE this type of allergy and a clear increase with regard to previous to Hymenoptera venoms. This misdiagnosis is in any case.

The patients with Hymenoptera allergy had a low score This can be a consequence of the illness itself, as it is most 25th percentilecompared with the general sample, in the frequently acute and self-limited in time. Furthermore, allergy mental component of the quality of life questionnaire. There are several factors that influence the risk of receiving Comparison with the Main Sample a sting.

The prevalence of Hymenoptera venom allergy is greater in men, median age, and in rural areas. The typical Several differences between the main sample of the study patient profile is of a man, living in a small village, working and that with allergy to venoms were found and these are outdoors farmer, building worker or gardener with a greater summarized in the Table 2.

Another contribution to these results The group with Hymenoptera allergy were mainly males is the fact that beekeepers and their family members are a Thus, older median age In wasp allergy, we found 0. We can insect allergy has a better prognosis in children than in adults conclude that in this trial the proportion between bee and [6]. However, due to the low number of epidemiologic studies wasps is similar, possibly because the data come from the that include children, we do not know if the prevalence of entire nation.

Hymenoptera allergy is lower at these ages. This low figure The type of reaction presented in different studies is could be possibly due to a lower level of exposure lower variable and depends on the kind of population included. In this number of stings due to short time of exposure.

The results would be different if this epidemiologic hospitalized and many of them were referred from emergency study had been carried out in the general population. It is important to note that in many cases the Most of the patients who suffered a reaction previous to emergency health assistance is provided by doctors in rural the generalized reaction experienced a strong local reaction.


Consequently, it is usual for cases of severe reactions, such as This controversial result can be explained by the fact that anaphylactic reactions, to be referred from emergency units. It was not a present with more severe reactions. If we accept that this is an under-diagnosed not described in detail. It is Epinephrine is the drug of choice to treat IgE-dependent necessary that allergists dedicate time and effort to spreading anaphylaxis.

The wide use of epinephrine in and family doctors, so patients can benefit from an effective these patients reflected good compliance with these guidelines. If primary prevention is not Anaphylactic reactions have often been under-treated and it possible it is not possible to know who will develop a systemic seems that we have improved in this aspect. All patients who have suffered a generalized systemic The severity of the reactions and the sensitivity of allergists reaction after a Hymenoptera sting should carry epinephrine to this problem were the causes of the short waiting time for for self-injection, especially in the warm season, where the these patients; as it was essential to make a quick diagnosis risk of stings is higher.

The situation is different when there is and start the immunotherapy as soon as possible. In these cases, the indication in other allergic disorders. The history must be compatible: Furthermore, these an acute allergic reaction after an insect wasp or bee sting, patients stop following this recommendation after a short suggestive of an IgE-mediated mechanism.

If so, then specific time [14]. IgE, both in vivo and in vitro should be measured: It is IgE measured to confirm the diagnosis. The importance of the also indicated if the reaction is slight or moderate and there are reaction and the risk of exposure determine the choice of which other risk factors. The indication for immunotherapy in this diagnostic tests to perform.

Local reactions are not a subsidiary group follows these criteria, so most reactions are severe. Sting challenge tests are not used regimens than in other kinds of extracts such as aeroallergens.

They are not indicated in patients The variability and geographical dispersion alergologcia the data who have not been treated with immunotherapy [14]. Honeybee, Vespula mix and Polistes mix. For most patients an allergic reaction after an insect sting is This last point is unknown because these data were not included a traumatic event.
