Abstract
Cochineal carmine, or simply carmine (E120), is a red colouring that is obtained from the dried bodies of the female insect Dactylopius coccus Costa (the cochineal insect). We have evaluated the prevalence of sensitization and asthma caused by carmine in a factory using natural colouring, following the diagnosis of two workers with occupational asthma. The accumulated incidence of sensitization and occupational asthma due to carmine in this factory are 48.1% and 18.5% respectively, figures that make the introduction of preventive measures obligatory. Occupational asthma caused by inhaling carmine should be considered as a further example of the capacity of certain protein particles of arthropods (in this case cochineal insects) to act as aeroallergens. Carmine should be added to the list of agents capable of producing occupational asthma, whose mechanism, according to our studies, would be immunological mediated by IgE antibodies in the face of diverse allergens of high molecular weight, which can vary from patient to patient. Nonetheless, given the existence of different components in carmine, it cannot be ruled out that substances of low molecular weight, such as carminic acid, might act as haptenes. Besides, since we are dealing with a colouring that is widely used as a food additive, as a pharmaceutical excipient and in the composition of numerous cosmetics, it is not surprising that allergic reactions can appear both through ingestion and through direct cutaneous contact. We find ourselves facing a new example of an allergen that can act through both inhalation and digestion, giving rise to an allergolical syndrome that can show itself clinically with expressions of both respiratory allergy and alimentary allergy.

Abstract
Latex has become one of the most frequent aetiological agents of occupational asthma in the last decade, especially amongst health personnel. The prevalence of occupational asthma due to latex in the different affected occupations varies between 2.5 and 10%, figures that give an idea of the magnitude of the problem. Latex proteins, absorbed in the dust of cornstarch, used as a lubricant, are responsible for asthma due to latex gloves. This cornstarch dust that covers the inside of the gloves acts as a vehicle for dispersing allergenic proteins. Latex aeroallergens are found in particles of different dimensions. The levels of latex aeroallergens in the environment capable of causing sensitization and of unleashing symptoms are not well defined. The determination of these levels of exposure to latex is complicated, since with latex one is dealing with a complex mixture of allergens with differing stability and bio-availability. The bioaerosol of latex is mainly produced by the active use of powdered gloves, but rugs or carpets and coverings act as important reservoirs of the allergen. Besides, the movement of people from areas with a high environmental concentration of latex constitutes an important means of dispersing the allergen, and probably ventilation systems as well. As in other cases of occupational asthma, diagnosis in many cases requires that a bronchial challenge be realized. The specific challenge tests through inhalation with latex have been carried out by different methods, which can be grouped by those that use an aqueous extract of latex and those that consist in handling or shaking gloves, which thus generate a dust aerosol. Each method has its advantages and drawbacks as described. Once the sensitized patient begins manifestations of the disease, his prognosis is poor if measures aimed at a maximum reduction of exposure to latex are not applied.

Abstract
BACKGROUND Chicken serum albumin (alpha-livetin) has been implicated as the causative allergen of the bird-egg syndrome. However, the clinical relevance of sensitization to this allergen has not been confirmed by specific challenge tests and environmental sampling. We investigated whether chicken albumin can be detected in air samples collected in a home with birds, and whether sensitization to this protein may cause respiratory and food allergy symptoms. The heat resistance of chicken albumin and the possible cross-reactivity with conalbumin were also investigated. METHODS We studied eight patients with food allergy to egg yolk who also suffered from respiratory symptoms (rhinitis and/or asthma) caused by exposure to birds. Sensitization to egg yolk and bird antigens was investigated by skin and serologic tests. Hypersensitivity to chicken albumin was confirmed by specific bronchial, conjunctival, and oral provocation tests. RESULTS All patients had positive skin tests and serum IgE against egg yolk, chicken serum, chicken meat, bird feathers, and chicken albumin. The presence of airborne chicken albumin in the domestic environment was confirmed. Specific bronchial challenge to chicken albumin elicited early asthmatic responses in six patients with asthma. An oral challenge with chicken albumin provoked digestive and systemic allergic symptoms in the two patients challenged. IgE reactivity to chicken albumin was reduced by 88% after heating at 90 degrees C for 30 min. ELISA inhibition demonstrated only partial cross-reactivity between chicken albumin and conalbumin. CONCLUSION Chicken albumin (Gal d 5) is a partially heat-labile allergen that may cause both respiratory and food-allergy symptoms in patients with the bird-egg syndrome.

Abstract
BACKGROUND Exposure to acrylates may give rise to rhinitis and asthma in both industrial and domestic environments. The mechanisms underlying these respiratory conditions caused by acrylates remain largely unknown. METHODS We studied two assembly operators exposed to cyanoacrylate glue who developed rhinitis and asthma symptoms. The causal relationship of these symptoms to cyanoacrylate glue exposure was investigated by serial peak expiratory flow (PEF) monitoring at work and off work. Moreover, inhalation testing was performed by asking the patients to mimic exposure at work with the cyanoacrylate glue in a 7-m3 challenge chamber. RESULTS Serial PEF monitoring at work and away from work was consistent with occupational asthma in both patients. The methacholine inhalation test was negative in patient 1 (off work) and showed bronchial hyperresponsiveness in patient 2. After 20-min exposure to cyanoacrylate, the patients had late and progressive asthmatic reactions, respectively, and the methacholine test became positive in patient 1. Induced-sputum samples obtained 3 and 24 h after the cyanoacrylate challenge showed a marked increase in sputum eosinophils. CONCLUSION Exposure to cyanoacrylate in these patients provoked not only variable airflow limitation and bronchial hyperresponsiveness, but also pronounced eosinophilia in sputum.

Abstract
There are some contradicting data about clinical allergic cross-reactivity to cephalosporins among patients who have had a previous allergic reaction to penicillins. The purpose of this study was to assess the safety of administering cephalosporins to penicillin-allergic patients. The diagnosis of penicillin allergy was made by positive skin tests to penicillin reagents and/or provocation tests with the penicillin suspected of causing the allergic reaction. To assess the clinical tolerance to cephalosporins, 41 well-characterized penicillin allergic patients diagnosed by positive skin tests and/or provocation tests were challenged with three cephalosporins that do not share the same side chain to the penicillin that induced the reactions: cephazoline, cefuroxime and ceftriaxone. Skin prick and intradermal tests with all cephalosporins tested were negative. All penicillin-allergic patients tolerated therapeutic doses of the three cephalosporins tested (cephazoline, cefuroxime and ceftriaxone) without any ill effect. These results indicate that the risk of suffering from an allergic reaction on administering cephalosporins to penicillin-allergic patients seems to be very low, provided that cephalosporins with a different side chain to the penicillin responsible for the allergic reaction are used.

Abstract
BACKGROUND Psyllium is the seed of the plant Plantago ovata, which is widely used in nonprescription laxatives. It has been reported that psyllium powder may act as an inhalant allergen, especially in the workplace. A patient with asthma due to inhalation of P. ovata seed powder is described, being highlighted the allergenic potential of this substance frequently used as a laxative. We report a 31 year-old atopic woman, who handled and prepared at home, twice daily, a laxative containing P. ovata seeds (Plantaben) prescribed to her paralytic mother. METHODS AND RESULTS Skin prick test to psyllium powder extract was positive. Specific IgE antibodies to psyllium were positive as determined by ELISA. Methacholine inhalation test revealed mild bronchial hyperresponsiveness (PC20 = 1.5 mg/ml). Specific bronchial challenge to psyllium powder elicited an isolated early asthmatic response. The allergens in psyllium were investigated by SDS-PAGE and immunoblotting, being identified several allergenic components with an apparent molecular weight of 66, 60, 36-20 and 14 kDa. No cross-reactivity was found between P. ovata seed and P. lanceolata pollen, as determined by ELISA-inhibition. CONCLUSION Psyllium may act as a potent inhalant allergen capable of eliciting asthma symptoms, not only in an occupational context, but also in a domestic environment, affecting consumers of this laxative or relatives who handle it.

Abstract
BACKGROUND The third-stage larvae of Anisakis simplex may be a hidden source of allergens in fish. The objective was to determine whether the ingestion of lyophilized A. simplex larvae, or antigen, induces clinical symptoms in a group of A. simplex-sensitized patients. METHODS Double-blind, placebo-controlled oral challenges were conducted in 11 individuals who had experienced allergic reactions after eating fish. Another patient had chronic urticaria unrelated to the ingestion of fish. All patients had positive skin tests and specific IgE determinations for A. simplex and negative skin tests to a battery of fish species. Conjunctival tests with A. simplex extracts were conducted in all patients and in five controls. The 12 patients received capsules containing either lactose or one, five, or 25 lyophilized larvae of A. simplex at 2-h intervals in a double-blind fashion. The highest single dose was 100 larvae. ECP and tryptase levels in serum were measured before and after the last oral challenge. Lyophilized antigen was also given to five patients. RESULTS None of the 12 patients experienced a positive reaction after the ingestion of the placebo, the lyophilized larvae, or the antigen. Tryptase and ECP levels before and after challenges did not change significantly. Conjunctival provocation tests were positive in 11 out of the 12 patients and in none of the controls. CONCLUSIONS The ingestion of 100 lyophilized A. simplex larvae, or its equivalent in antigen, does not induce clinical symptoms in individuals with a clinical history and laboratory findings of hypersensitivity to A. simplex. The data suggest that only the ingestion of live larvae may be capable of inducing allergic manifestations.

Abstract
BACKGROUND Soybean dust has been identified as the causative agent of occupational asthma and asthma epidemics. Two main soybean hull allergens responsible for asthma outbreaks, Gly m 1 and Gly m 2, have been identified and purified. OBJECTIVE The soybean allergens causing occupational asthma in exposed bakers were investigated and compared with those involved in epidemic asthma. METHODS We report four bakers or confectioners with work-related respiratory symptoms who were exposed to soybean flour used as a baking additive. The causative role of soybean flour was investigated by immunological tests and specific inhalation challenge tests. Soybean flour allergens causing occupational asthma were characterized by immunoblotting. Immunoglobulin (Ig) E-reactivity to Gly m 1 and Gly m 2 was assessed using enzyme-linked immunosorbent assay. RESULTS Sensitization to soybean flour was demonstrated by skin and serological tests and was confirmed by positive inhalation tests. Bronchial challenge test to soybean flour extract elicited immediate or dual asthmatic responses. Immunoblotting with soybean flour and soybean hull extracts showed IgE-binding mainly to high molecular weight (MW) allergens. There was an important individually different allergic response to inhalant soybean components. None of the patients showed IgE-reactivity against Gly m 1 and only one patient showed IgE-reactivity to the soybean hull allergen Gly m 2. CONCLUSION These bakery workers had developed IgE-mediated occupational asthma to soybean flour. The allergens involved in occupational asthma caused by soybean flour are predominantly high MW proteins that are present both in soybean hull and flour, and they are different from the allergens causing asthma outbreaks, which are mainly low MW proteins concentrated in the hull.

Abstract
BACKGROUND Carmine has been implicated as an etiologic agent of occupational asthma, but the allergens involved have not been yet identified. OBJECTIVE To identify the allergens involved in occupational asthma due to carmine dye. METHODS An in vitro study based in SDS-PAGE and IgE immunoblotting with carmine and cochineal extracts was performed. Sera from three carmine dye workers diagnosed with occupational asthma induced by carmine dye and from seven nonatopic subjects were used. RESULTS Three proteins of around 30, 28, and 17 kD in raw cochineal extract and another protein of 50 kD in the boiled one were demonstrated by SDS-PAGE. Two proteins of around 50 and 28 kD were observed in the carmine extract by the same technique. Specific IgE binding bands at 17 kD in cochineal raw extract, at 50 kD in the boiled one, and at 28 kD in carmine extract were demonstrated by IgE immunoblotting. CONCLUSIONS We have identified three allergens of around 17, 28, and 50 kD implicated in occupational asthma of three carmine workers.

Abstract
We report on three patients who experienced persistent asthma symptoms after repetitive irritant exposure which took place over a period from several days to months. Airway inflammation was assessed by induction of sputum and functional follow-up information was obtained from serial lung function tests. All patients had bronchial hyperresponsiveness to methacholine at the time of diagnosis. However, induced sputum samples did not show increased differential count of eosinophils. Treatment with inhaled corticosteroids was started in all of the patients and two of them were removed from work. In the two patients who left the workplace, methacholine inhalation test became negative when symptoms disappeared, whereas the patient who continued working had persistent asthma symptoms and a deterioration of bronchial hyperresponsiveness.

Abstract
BACKGROUND An association between allergy to fruits and latex, and between pollen and plant-derived food has been described. The cross-reactive structures responsible for these associations have not yet been completely elucidated. METHODS IgE reactivity to the recombinant allergens Bet v 1 and Bet v 2, different pollens, natural latex, papain, and bromelain was investigated in 29 patients with allergy to fruits or vegetables who lived in an area without birch trees. RESULTS Exactly 79.3% of patients were allergic to grass pollen, and two of them had clinical allergy to latex. Serum IgE reactivity (CAP) to birch pollen was found in 65% of patients, to Bet v 2 in 51.7%, to Bet v 1 in 3.4%, to latex in 58.6%, to bromelain in 51.7%, and to papain in 17.2% of patients. All subjects with positive IgE to Bet v 2 had also reactivity to latex, grass, olive tree, birch, and mugwort pollens. The six patients not allergic to pollen did not show IgE reactivity to latex, Bet v 1, or Bet v 2. A significant correlation was found between CAP to latex with Bet v 2 (r=0.86, P<0.001), with birch (r=0.86, P<0.001), and with ryegrass (r=0.81, P<0.001). Immunoblotting using nine sera with positive CAP to birch pollen showed IgE-binding to a 15-kDa band that was recognized by antiprofilin monoclonal antibody. Bet v 2 CAP could be inhibited up to 52% by ryegrass and up to 23% by mugwort. CAP to latex was almost completely inhibited by ryegrass pollen with sera from five subjects without symptoms due to latex, whereas no inhibition was observed with serum from one patient with allergy to latex. CONCLUSIONS Patients with allergy to plant-derived food and associated pollinosis showed a high frequency of IgE reactivity to Bet v 2, which may cause positive serum IgE determinations to latex and birch pollen due to the presence of cross-reactive epitopes. IgE reactivity to Bet v 2 may serve as an indicator of broad sensitization.

Abstract
BACKGROUND We report on a patient who experienced allergic reactions after eating goat cheese and after touching goat and sheep cheese, but not after consuming cow's milk dairy products. OBJECTIVE To assess the allergenicity and IgE-binding capacity of the caseins from the three different species. METHODS Skin prick tests were carried out using whole milk and caseins from three different species (goat, sheep and cow), and whey fractions of cow's milk. Total serum IgE and specific IgE to cow's milk proteins were measured by CAP system and specific IgE against caseins and whole milk were determined by ELISA technique. To evaluate allergenic cross-reactivity, inhibition of the IgE ELISA activity to goat's milk and goat casein was tested for the three caseins. SDS-PAGE and immunoblotting was used to determine IgE binding bands in caseins. RESULTS Skin tests were positive to sheep and goat's milk, sheep and goat casein, as well as to sheep and goat cheese. Total serum IgE was 66 kU/L and IgE determinations by CAP were negative. IgE ELISA against the caseins from goat and sheep was strongly positive, whereas it was negative to cow casein. ELISA inhibition assays revealed a high degree of cross-reactivity between goat casein and sheep casein. Immunoblotting showed three IgE-binding bands in goat casein at 31, 27 and 22 kDa, which may correspond to alpha-, beta- and gamma-caseins. A band at about 31 kDa was observed in sheep casein and another band at 34 kDa was recognized in cow casein. CONCLUSION This patient developed allergy to goat and sheep cheese with good tolerance to cow's milk. We identified goat casein as the main allergen causing sensitization in this patient as demonstrated by in vivo and in vitro tests. A high degree of cross-reactivity between goat and sheep casein was observed.

Abstract
BACKGROUND We report on a 21-year-old atopic woman who developed urticaria, angioedema of the face, and wheezy dyspnea shortly after drinking beer and after eating a corn-made snack. METHODS Skin prick tests and specific IgE determinations to beer ingredients and cereal extracts were performed. Immunoblotting inhibition assays were carried out to investigate possible common allergens shared by barley and malt with corn. RESULTS Skin prick tests and specific IgE measurements with beer, barley, malt, wheat, corn, rye, rice, and oat flour were positive. Ten pollen-allergic patients showed negative skin tests to beer. Double-blind, placebo-controlled, oral challenge tests with sodium metabisulfite and wheat flour were negative. Immunoblotting demonstrated several IgE-binding bands at 31-56 kDa in malt and barley extracts, and a major band at 38 kDa in the beer extract. Immunoblot inhibition assays showed that malt extract was able to inhibit most of the IgE-binding bands in wheat and corn extracts, whereas corn did not produce significant inhibition to barley and malt extracts. CONCLUSIONS This patient developed type I hypersensitivity to barley/malt and corn. Although she also showed IgE reactivity to wheat and other cereals, no symptoms were elicited upon ingestion of these cereals, probably indicating latent sensitization to them.

Abstract
A 20-yr-old pharmaceutical worker who developed attacks of shortness of breath and wheezing 9 months after beginning work on a process in which cefadroxil powder was bottled or encapsulated will be described. Skin test with cefaxodril was negative. Baseline spirometry and methacholine inhalation test were normal. A controlled bronchial challenge test was carried out in a closed-circuit system with assessment of respirable dust concentration. Exposure to cefadroxil powder at a mean concentration of 10 mg x m(-3) for 10 min elicited an isolated immediate asthmatic response, but no response was observed to control challenge with lactose. Single-blind oral challenge test with amoxicillin up to 500 mg was well tolerated, whereas the oral challenge with cephalexin (25 mg) elicited an immediate asthmatic response. This patient had developed occupational asthma caused by inhalation of cefadroxil as confirmed by specific inhalation test. Since she tolerated oral amoxicillin, a synthetic penicillin with the side-chain identical to that of cefadroxil, it seems that she may be sensitized to the dihydrothiazine ring of cephalosporins.

Abstract
We designed a cluster schedule of immunotherapy for patients allergic to Dermatophagoides pteronyssinus which showed good safety and clinical efficacy. Here we compare the in vivo and in vitro changes with those of a conventional schedule in a controlled trial. Sixty-three patients were randomized as follows: 29 were treated with the cluster schedule, 15 with a conventional schedule and 19 received no immunotherapy. A standardized extract was used. Changes in in vivo parameters (skin prick test and conjunctival provocation test) and in in vitro parameters (IgE, IgG, IgG1 and IgG4 for the complete extract, Der p 1 and Der p 2) were measured before immunotherapy (T0), on reaching maintenance phase (T1), and after 6 (T2), 12 (T3) and 18 months of maintenance (T4). Cutaneous reactivity showed a significant decrease from T1 in both the cluster and conventional schedules, and conjunctival reactivity was also significantly lowered from T1 in these groups. Specific IgE decreased and specific IgG, IgG1 and IgG4 increased significantly from T1 in the cluster and conventional schedules. Neither of these parameters showed any changes in the group without immunotherapy. In conclusion, our cluster schedule induced changes in cutaneous and conjunctival reactivity and in immunological parameters that were similar to those achieved with the conventional schedule; these changes did not appear in patients who did not undergo immunotherapy.

Abstract
A significant number of cases of chronic eosinophilic pneumonia remain idiopathic in spite of a comprehensive search of associated causes. This study reports a patient with a classical clinical presentation of chronic eosinophilic pneumonia and peripheral blood eosinophilia in whom selective sensitization to Candida albicans was demonstrated. This yeast was present in the bronchoalveolar lavage culture and specific serum immunoglobulin (Ig)E and IgG against C. albicans were found in the patient's serum. Levels of these specific immunoglobulins diminished with corticosteroid treatment and increased coinciding with a new outbreak of symptoms after lowering the dosage of corticosteroids. To the author's knowledge, this is the first case described of chronic eosinophilic pneumonia associated with sensitization to C. albicans. Evaluation of allergy to C. albicans should be performed in chronic eosinophilic pneumonia before labelling cases as idiopathic.

Abstract
BACKGROUND T cells are known to play a major role in the pathogenesis of atopic allergic asthma, but it is less clear whether they are involved in occupational asthma caused by low molecular weight chemicals such as plicatic acid. OBJECTIVES We sought to determine whether peripheral blood T cells from patients with western red cedar asthma (WRCA) recognize plicatic acid (PA) conjugated to human serum albumin (HSA) as judged by proliferation or cytokine production and to analyze the response to PA inhalation with flow cytometry. RESULTS Significant proliferative responses to PA-HSA were observed in eight of 33 patients with WRCA, none of 10 exposed nonasthmatic cedar workers, and one of 18 nonasthmatic control subjects. Two of 25 patients with WRCA also showed proliferative responses to unconjugated PA. All the WRCA responders were either currently exposed to cedar or had ceased exposure within the preceding 2 years. None of the four patients receiving oral steroids responded, but inhaled steroids did not seem to influence responsiveness. No correlations were found between the maximum stimulation response and any of the current FEV1 values, the current PC20 methacholine values, or the magnitude of the late asthmatic response to PA. Peripheral blood T-cell subset proportions and their degree of activation were similar in patients with WRCA and exposed control subjects. There was no change in T-cell phenotypes or their activation markers after PA inhalation challenge. In vitro, PA-HSA stimulation did not affect subset ratios but led to release of small amounts of IL-5 and IFN-gamma, with no detectable increase in IL-4. CONCLUSIONS PA-HSA-specific T lymphocytes seem to be present in small numbers in the peripheral blood of patients with WRCA and may respond to antigenic exposure by producing IFN-gamma and IL-5. However, the proportion of responding cells would appear to be lower than in comparable studies of atopic asthma.

Abstract
BACKGROUND Several egg white and egg yolk and avian proteins have been described as a cause of inhalant allergy. Sometimes inhalational type I hypersensitivity to these proteins is associated with food allergy to egg. OBJECTIVE We studied two patients who experienced respiratory and food allergic symptoms upon exposure to egg or avian antigens through the inhalative or digestive routes. Clinical and immunological studies were carried out in order to identify individual allergens from these sources that could be responsible for crossreactivity reactions. RESULTS Patient 1 showed IgE sensitization to egg yolk livetins, feathers, and chicken serum. Specific bronchial challenge with chicken albumin and livetin extracts elicited a positive early asthmatic response and an increase in serum eosinophil cationic protein. Immunoblot and CAP-inhibition studies in this patient supported that chicken albumin (alpha-livetin) was the crossreactive antigen present in egg yolk and chicken serum and feathers. Patient 2 showed sensitization to egg white, ovomucoid and lysozyme. However, SDS-PAGE and immunoblot studies demonstrated contaminating lysozyme in the ovomucoid extract and identified lysozyme as the main allergen causing egg sensitization in this patient. Conjunctival challenge test confirmed allergy to lysozyme. CONCLUSION Egg yolk and egg white proteins may act not only as ingested allergens but also as aeroallergens. Immunological studies using highly purified preparations of egg proteins are useful for the accurate diagnosis of allergic reactions to egg proteins and to identify individual allergens that may be responsible for crossreactivity reactions.

Abstract
Reactive airways dysfunction syndrome (RADS) is a type of asthma that develops in subjects without prior pulmonary disease, following single or multiple exposure to high levels of nonimmunogenic irritants. The main difference from classic occupational asthma is the absence of a latency period. Non-specific bronchial hyperresponsiveness is characteristic of the disease and usually persists after cessation of exposure. We report the cases of two subjects in whom RADS developed after occupational exposure to irritants.

Abstract
We describe a woman with hypersensitivity pneumonitis that was related to using a home ultrasonic humidifier. A micronodular infiltrate was seen in her chest radiograph. The inhalation challenge test was performed with the humidifier, and she exhibited a positive response. The cultures of the humidifier water grew Candida albicans, Rhodotorula spp., and Aspergillus spp. The test for precipitating antibodies against the humidifier water gave a positive response, and specific IgG, IgM, and IgA antibodies against extracts of A. fumigatus, C. albicans, and Rhodotorula spp. were demonstrated in the patient's serum by ELISA. A strong, dose-dependent inhibition of Rhodotorula IgG-ELISA by humidifier water was observed, suggesting that Rhodotorula might be the cause of hypersensitivity pneumonitis in this patient.

Abstract
BACKGROUND Ficus benjamina or weeping fig is a plant used increasingly for indoor decoration that can cause allergic rhinitis and asthma. OBJECTIVE We report a clinical and immunologic study in a patient with perennial asthma caused by F. benjamina latex in whom several episodes of angioedema of the oropharyngeal tract and tongue followed ingestion of figs and kiwi. METHODS Hypersensitivity to latex from F. benjamina and from Hevea brasiliensis, fig fruit, kiwi, papain, and bromelain was investigated by means of skin prick test, specific IgE determination by CAP, histamine release test, and bronchial provocation test to F. benjamina latex. CAP-inhibition assays were carried out to study possible cross-reactivity among these antigens. RESULTS Hypersensitivity to F. benjamina latex, fig, kiwi, and proteases was demonstrated by means of skin prick test, determination of specific IgE and histamine release test. Bronchial provocation test with F. benjamina latex resulted in a dual asthmatic reaction, confirming the etiologic role of this plant. A rise of eosinophil cationic protein in patient's serum was observed 21 hours after bronchial challenge, suggesting activation of eosinophils. Inhibition assays showed that F. benjamina latex as liquid-phase inhibited up to 95% the CAP to fig and up to 57% the CAP to papain. Neither sensitization nor cross-allergenicity with H. brasiliensis latex was found. CONCLUSIONS Hypersensitivity to F. benjamina latex may cause IgE-mediated respiratory allergy. The association with allergy to fig and papain is likely due to the existence of cross-reactive allergen structures.

Abstract
BACKGROUND Indoor allergens are common causes of sensitization and asthma. Climatic and home conditions can modify their levels. OBJECTIVE We studied the influence of climatic conditions and home characteristics on the exposure to indoor allergens of mite allergic asthmatic subjects in two Spanish cities with different climates (Las Palmas and Pamplona). METHODS We included 65 subjects diagnosed with asthma caused by Dermatophagoides pteronyssinus. A questionnaire about their dwellings was completed. Home dust samples were collected. Mite (Der p1, Der f1, Der 2) and cat (Fel d1) allergens were measured by a monoclonal-antibodies based ELISA. RESULTS Characteristics of dwellings were similar in both areas. Der p1 was the main allergen (0-44 micrograms/g). Der p1, Der f1 and Der 2 levels were higher in the homes in Las Palmas (p < 0.001, p < 0.01 and p < 0.001, respectively). Damp homes in Pamplona had higher Der p1 levels, similar to those detected in homes in Las Palmas. Fel d1 levels (0-78.90 micrograms/g) were only related to the presence of cats in the dwelling (p < 0.001). CONCLUSIONS D. pteronyssinus allergen exposure was influenced by climatic conditions and dampness in homes in temperate regions. Humidity in homes can generate an ideal environment for mite growth despite unfavorable outdoor climatic conditions. Fel d1 levels were only related to the presence of a cat in the house.
