Extended IgE profile of shrimp-sensitized patients based on Multiplex Examination ALEX2 - Allergy Explorer. Postepy Dermatol Alergol 2023; 40:661-669. [PMID: 38028417 PMCID: PMC10646718 DOI: 10.5114/ada.2023.132071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 07/27/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction The key to the correct diagnosis of shrimp allergy is a qualification to the most efficient diagnostic method and later interpretation of the result. To achieve this, it is necessary to apply a diagnostic strategy relevant to each patient's clinical situation and approach every case individually. Aim In this study the allergen profile of shrimp-sensitized patients was analysed using ALEX2 Allergy Explorer. Material and methods This study includes 50 adult patients with positive prick-by-prick tests with tiger shrimp bought from the local eco-market and an elevated concentration of IgE specific to the shrimp allergen extract (ImmunoCap). A total of 35 patients with negative skin prick tests with shrimp and not detectable sIgE shrimp in ImmunoCap were included in the control group. All patients had ALEX2 Allergy Explorer microarray test. Results In the shrimp-sensitized group, 22 patients were sensitized to at least one allergen component of Penaeus monodon, 20 patients were sensitized to crab, and 20 were sensitized to lobster. Only 15 (30%) patients were sensitized to the Northern prawn (Pandalus borealis) allergen extract in ALEX2 and only 12 (24%) to Shrimp mix (Litopenaeus setiferus, Farfantepenaeus aztecus, Farfantepenaeus dourarum). Conclusions Sensitization to shrimp tropomyosin in the research group was present only in 34% of cases. There may be other shrimp allergen components, not available in ALEX2, which are responsible for shrimp sensitization.

Abstract
Background An allergy to kiwi is rare in Poland. Most (65–72%) of the patients who are allergic to kiwi report symptoms of an oral allergy syndrome (OAS); however, systemic manifestations (18–28%) have also been reported. Case report A 27-year-old male patient, previously not suffering from chronic diseases, exercised in the gym. He began with isometric training and then continued with aerobic exercise on a treadmill. After exercise, he ate 2 kiwi (Actinidia deliciosa) fruits. He experienced a swelling of the lips after eating the fruit, followed by an itchy scalp and a swollen face. Approximately 60 min later, the symptoms worsened: the patient suffered from generalized hives, general weakness and a "rumbling" sensation in ears. The patient's condition improved upon the consumption of antihistamines. However, the swelling of the face persisted for 24 h despite previously eating a kiwi without any side effects. By means of diagnostics based on allergen components, an allergy to grass allergen components, especially timothy grass—Phl p 1, Phl p 2 and Phl p 5, was confirmed. The presence of IgE that is specific for Act d 2 kiwi was also found. The patient had an oral food challenge with kiwi fruit at rest and after exercise provocation test. The challenge was negative at rest and positive after exercise. A food-dependent exercise-induced anaphylaxis gathered with a kiwi sensitization was diagnosed. Conclusion To our knowledge, this case is the first report of a kiwi-allergic patient in whom exercise was a necessary cofactor to induce an anaphylactic reaction.

Circulating Leptin, Adiponectin, and Tumor Necrosis Factor-Alpha in Patients Undergoing Surgery Due to Colorectal Cancer. Digestion 2021; 102:246-255.

Abstract
BACKGROUND Adipocytokines have been proposed as factors mediating associations between obesity and inflammation in patients with colorectal cancer (CRC). Thus, the aim of this study was to determine the clinical relationships between blood concentrations of leptin (LEP), adiponectin (ADP), and tumor necrosis factor alpha (TNF-alpha) and the outcomes measured in patients with CRC undergoing surgery. PATIENTS AND METHODS History, body composition, and blood concentrations of LEP, ADP, and TNF-alpha were determined in 107 patients undergoing surgery due to CRC. The patients were followed up for 619.72 ± 371.65 days. RESULTS Compared to patients with stage II CRC, individuals with clinical stage I CRC had significantly lower ADP and higher TNF-alpha blood concentrations. We found significant correlations between the clinical stage of CRC (early vs. localized vs. metastatic) and the following: crude blood ADP concentration (R = 0.25; p = 0.015), ADP-to-TNF-alpha ratio (R = 0.31; p = 0.002), and ADP when indexed to body surface area (R = 0.25; p = 0.008) and to fat mass (R = 0.25; p = 0.016). The risk of death during the long-term follow-up period was independently related to the clinical stage of CRC, impairment of the patient's functional status, and higher blood carcinoembryonic antigen concentration. In Kaplan-Meier survival analysis, patients with blood LEP concentrations adjusted to a visceral adipose tissue score of ≥0.47 had a significantly better likelihood of surviving than their counterparts. CONCLUSIONS In patients with CRC undergoing surgery, blood ADP and TNF-alpha concentrations were associated with the clinical stage of the cancer, likelihood of radical tumor excision, occurrence of nonsurgical postoperative complications, and long-term survival, which suggests the role of dysregulation in the endocrine function of adipose tissue in response to the neoplasmatic process.

Abstract
Background Shrimp allergy is a growing problem among the European population. TSLP, IL-25 and IL-33 are involved in the pathophysiology of allergic diseases, including asthma and atopic dermatitis, as they activate the Th2-dependent immune response. Methods Thirty-seven patients (18 male and 19 female) with a positive history of symptoms associated with shrimp consumption were selected. All patients had blood samples taken to assess the concentration of allergen-specific IgE (sIgE) to house dust mites (HDM) and shrimp (Singleplex, quantitative method with cut off value > 0,35 kAU/L) as well as the level of allergen components using the ImmunoCap ISAC method (Microarray test, semi-quantitative with cut off value > 0,3 ISU-E). The concentrations of TSLP, IL-25 and IL-33 in the patients’ blood serum was assessed using the ELISA method (Cusabio). Twenty patients with negative allergy history of allergic disease tests were included in the control group. Results Among the 37 shrimp-allergic patients, ImmunoCap ISAC was identified the presence of sIgE to the available shrimp allergen components in only 14 cases (37.8%). TSLP and IL25 levels were significantly higher in the study group. No statistically significant correlation was found between the concentration of analyzed alarmins and the concentration of sIgE level to shrimp or HDM between the study and control groups. No statistically significant correlation was found between poly-sensitization occurring in patients and levels of TSLP, IL-25 and IL-33 . Conclusion In shrimp-allergic patients, the concentrations of TSLP and IL-25 were significantly higher than in the control group (1.33 vs. 0.49 and 157 vs. 39.36, respectively). There was no correlation between the concentrations of TSLP, IL-25 and IL-33 and the concentration of sIgE in the patients or the number of allergen components that the patients were sensitized to.

Abstract
BACKGROUND Levels of specific IgE (sIgE) against allergen components can be assessed using multiplex assays or with highly sensitive, quantitative methods. The aim of this study was to compare the sensitivity and specificity of different immunological methods for diagnosis of shrimp allergy. METHODS Twenty patients with positive skin prick tests for frozen tiger shrimp were selected for further examination. Blood samples were taken to assess concentrations of sIgE against the house dust mites Dermatophagoides pteronyssinus and D. farinae, shrimp allergen extract, allergen components Der p 1, Der p 2 and Pan a 1 (ImmunoCap), and the ImmunoCap ISAC 112 panel. RESULTS All patients had elevated levels of sIgE against shrimp and D pteronyssinus. Eight patients were sensitized to Pen m 1, three patients were sensitized to Pen m 2, and two patients were sensitized to Pen m 4 (ISAC). ImmunoCap ISAC detected shrimp sensitization in 50% of patients. There was a strong correlation between concentrations of sIgE against Pen m1 and Der p 10 detected by ImmunoCap. CONCLUSIONS The singleplex ImmunoCap system remains the reference diagnostic method, but in the case of shrimp allergy ImmunoCap ISAC provided better insight into patient allergen profiles.

Abstract
Shrimp tropomyosin has a similar structure to house dust mite (HDM) tropomyosin.
In this research, 232 adult patients with symptoms of persistent allergic
rhinitis were randomly selected. In the group, 59% were sensitized to
Dermatophagoides pteronyssinus and 57.8% to
Dermatophagoides farinae. In total, 128 (55.2%) patients
were sensitized to both HDM species and 143 (61.6%) to at least one. Slightly
over a quarter (25.4%) of patients were sensitized to shrimp. Of the 35
shrimp-sensitized patients, the sensitization to Der p 10 and Pen a 1 was found
in 11 cases (31.4%). There was a strong correlation between IgE Pen a 1 and IgE
Der p 10 concentrations. The results indicate that there are other allergens
responsible for a high incidence of shrimp sensitization in HDM-sensitized
patients. A high convergence of Der p 10 and Pen a 1 levels may indicate that
the determination of just one of the above is reasonable.

Abstract
Can f 5 allergy and possible cross-reactivity with human semen in which there are significant amounts of prostate-specific antigen (PSA) are particularly interesting aspects of allergy to dog. The objective of the study was to confirm cross-reactivity between human PSA and Can f 5 in a study of canine sensitised women. A total of 100 women (aged 18-73, 41 on average) with a positive history of animal fur allergy or positive skin prick tests to canine allergens were selected. Levels of Immunoglobulin E (IgE) specific to Can f 1, Can f 2, Can f 3, Can f 5 were determined. Patients with increased concentration of sIgE Can f 5 were selected for further inhibition testing using polystyrene microplate ELISA test coated with human PSA. In the studied population, allergy to Can f 5 dominated (52.3% of patients with increased concentration of canine-specific IgE were allergic to this allergenic component). In all analyzed cases, the concentration of IgE Can f 5 decreased after incubation on the ELISA plate coated with human PSA. The minimum decrease in concentration was 10.44%, the maximum was 37.73%, the average decrease was 21.6%. No statistically significant influence of the presence or absence of allergenic sIgE Can f 5 in blood serum on the occurrence of symptoms after intercourse was found. The study confirmed the moderate ability of Can f 5 to cross-react with human PSA sIgE, which may be clinically significant in some women. At the same time, symptoms of an allergy to male semen do not constitute a typical clinical presentation of allergy to Can f 5.

Abstract
BACKGROUND Inflammatory responses mediated by adipocytokines may affect both atherosclerosis development and progression, as well as the risk of in-stent restenosis. The aim of this study was to determine the relationships between blood leptin, adiponectin and tumor necrosis factor-α (TNF-α) concentrations and the 1-year outcome of superficial femoral artery (SFA) stenting. METHODS Blood concentrations of leptin, adiponectin and TNF-α were determined in 70 patients undergoing SFA stenting due to intermittent claudication and in 40 patients undergoing carotid artery stenting (CAS). All subjects were followed up for at least 1 year in relation to the occurrence of clinically driven target lesion revascularization (TLR) or a major adverse cardiovascular event (MACE). RESULTS Patients undergoing SFA stenting and CAS had similar blood adipocytokine concentrations. Patients with diabetes mellitus presented a higher leptin concentration, lower adiponectin-to-leptin ratio, and lower blood adiponectin concentration indexed to fat mass (FM) and to visceral adiposity score (VAS). In Kaplan-Meier analysis, blood concentration of TNF-α indexed to FM and to VAS was higher in patients who underwent TLR and MACE. However, in multifactorial analysis, the severity of atherosclerosis lesions in the femoropopliteal vascular region, estimated in relation to TASC-II classification, was the only predictor of TLR. CONCLUSIONS Circulating adipocytokines did not distinguish patients with different clinical manifestations of atherosclerosis. Higher ratios of TNF-α -to-FM and to VAS before SFA stenting were related to TLR and MACE occurrence. Dysregulation in adipocytokine secretion may be a potential mediator of a proatherogenic action of diabetes mellitus in patients with peripheral artery disease.

Abstract
OBJECTIVES Venom immunotherapy (VIT) is an effective treatment method and is addressed to patients with a history of an anaphylactic reaction to Hymenoptera stings. However, the immunological mechanisms of protection have not been explained yet. The objective of this study was to analyze neutrophils, interleukin 8 (IL-8) and interleukin 17 (IL-17) before and after the initial phase of the immunotherapy. MATERIAL AND METHODS Overall, 40 individuals, including 20 wasp venom sensitized and 20 bee venom sensitized patients, were included in the study. The patients had had a history of severe allergic reactions type III and IV according to Mueller's classification. An ultra-rush VIT protocol was used in this study. The concentration of serum IL-8 and IL-17A was determined using the ELISA enzymatic method. RESULTS The authors demonstrated a significant rise in the IL-8 level after the immunotherapy, compared to baseline (14.9 vs. 24.7, p < 0.05). The rise in the neutrophils level was also noticeable but proved to be barely out of the range of statistical significance (4.3 vs. 5.0, p = 0.06). The shift in IL-17A was negligent and not statistically significant in the paired samples t-test (1.6 vs. 1.5, p = 0.34). CONCLUSIONS Venom immunotherapy induces neutrophils and IL-8 activity after 2 days. After the desensitization, the level of IL-17A did not change. Int J Occup Med Environ Health. 2020;33(6):811-7.

Abstract
INTRODUCTION Food allergy affects 6-17% of Europeans and in 60% of the cases it is accompanied by inhalation allergy. This is due to two phenomena, namely co-sensitisation and cross-reactivity, which are caused by panallergens, such as lipid transfer proteins (LTP). These proteins are classified as defence proteins PR-14 and are responsible for protecting the plant from bacterial and fungal infections. Clinically, LTP allergy manifests with severe anaphylactic reactions or milder reactions, such as oral allergy syndrome. AIM To assess the incidence of specific IgE to components belonging to LTP based on molecular testing. MATERIAL AND METHODS The study was conducted at the Department of Allergy, Clinical Immunology and Internal Diseases in Bydgoszcz, Poland. A total of 50 subjects participated in the study. Each subject had their asIgE levels determined with ImmunoCap ISAC. RESULTS AND CONCLUSIONS Antigen-specific IgE antibodies to LTP components were identified in 24% of the subjects. In subjects with LTP allergy, adverse skin reactions were the most common after consumption of sensitising foods. Peach was the most common food allergen triggering these reactions. The Artemisia vulgaris component Art v 3 was the precursor of LTP allergy in our study population: the highest incidence and the highest mean levels of asIgE were demonstrated for this component.

Abstract
BACKGROUND The endocrine function of adipose tissue and skeletal muscles mediates the risk of cardiovascular complications of obesity. AIMS The aim of this study was to determine the associations of leptin, adiponectin (ADA), tumor necrosis factor α (TNF‑α), and irisin levels with the diagnosis of atrial fibrillation (AF) on admission to the hospital as well as parameters of transthoracic echocardiography among inpatients with cardiovascular diseases (CVDs). METHODS The study included 80 consecutive patients hospitalized due to paroxysmal or persistent AF and a control group of 165 age- and sex‑matched individuals admitted due to exacerbation of chronic CVD. In all participants, we assessed serum leptin, ADA, TNF‑α, and irisin concentrations, body composition determined by bioelectrical impedance analysis, and transthoracic echocardiographic parameters. RESULTS Compared with controls, patients with AF had greater fat mass (FM), higher serum leptin levels and lower levels of ADA, TNF‑α, and irisin when indexed to body surface area, FM, and visceral adiposity. Hyperleptinemia slightly increased the risk of AF (odds ratio [OR], 1.02; 95% CI, 1.01-1.03; P <0.01). The correlation was stronger after indexation to FM (OR, 1.34; 95% CI, 1.01-1.81; P <0.05). The coefficients of significant correlations with echocardiographic parameters were stronger for irisin than for adipocytokines: 0.16 to 0.35 and 0.12 to 0.22, respectively. CONCLUSIONS Adipocytokines and irisin exert a significant but weak effect on heart chamber size and affect the risk of AF occurrence. Their blood concentrations do not seem to be related simply to body composition but probably depend on individual variations in adipocytokine and myokine secretion as a result of numerous factors.

Abstract
Determining the single factor that triggered anaphylactic shock can be challenging. We present an interesting case of a 25-year-old female patient with recurrent anaphylactic reactions developing after eating various foods, particularly in presence of co-factors of allergic reactions. Symptoms occurred after consumption of various kinds of foods - peach, pancakes with cottage cheese and fruit, a meal from a Chinese restaurant - all eaten on other occasions without symptoms. During diagnosis, skin prick tests were negative for all tested allergen extracts (both inhalatory and food) from Allergopharma. Prick by prick tests were positive for the peach - wheal diameter - 6 mm, nectarine - 4 mm (histamine 4 mm, negative control 0 mm). Increased levels of asIgE were found for allergens of peach (0.55 kU/L).Open challenge test with one mid-size peach combined with the physical exercise challenge test was positive. ImmunoCAP ISAC test indicated increased levels of IgE specific for the lipid transfer protein (LTP) for walnut (nJug r 3), peach (Pru p 3), wheat (rTri a 14) and plane tree (rPla a 3). The patient was diagnosed with food-dependent, exercise-induced anaphylaxis associated with an allergy to lipid transport proteins (LTPs).

Abstract
Background An allergy to mango is extremely rare. The antigenic composition of the fruit is not fully known. Profilin from mango has a structure similar to birch tree profiling: it is responsible for cross-reactions between mango and pear, apple, and peach. A panallergen with a structure similar to mugwort defensin (Art v 1) which cross-reacts with celery, carrot, peanuts, pepper, aniseed, and caraway has been previously described. Case study A female patient, 30 years old, was admitted in February 2017 because of recurrent allergic reactions following consumption of various foods. The most severe allergic reaction in the patient’s life occurred after eating a mango fruit. Within several minutes the patient developed a generalised urticaria, followed by facial oedema, strong stomach pain and watery diarrhoea. The diagnostics involved skin tests with a set of inhalatory and food allergens, including native skin tests. The patient also experienced symptoms of recurrent, generalized urticaria in connection with consumption of various types of food, especially complex dishes containing many different ingredients. Additionally, an interview revealed that the patient was experiencing symptoms of the oral allergy syndrome after ingesting various fruit and vegetables, especially during late summer and fall. Diagnostics was extended by determining the levels of IgE specific for allergen components, using the ImmunoCap ISAC method. In order to confirm the occurence of a cross-reaction between mugwort and mango allergens, we performed the inhibition test of IgE specific for mugwort using a mango allergen extract and ImmunoCap matrix. Results Skin prick tests (SPT) were positive for allergens of grass 7 mm; weeds 8 mm; cat’s fur 5 mm; mugwort 6 mm. SPT were also positive for mango. The level of specific IgE was increased for allergens of mugwort, grass, celery, pepper, carrot, mango, banana, peach, and apple. The ImmunoCap ISAC test demonstrated a high level of specific IgE rPhl p 1 (timothy grass) and Art v 1 (mugwort). We also performed the IgE inhibition test using both mango extract and ImmunoCap matrix and confirmed a cross-reaction with Art v 1 in the pathogenesis of symptoms observed in the patient. Conclusions An anaphylactic reaction to consumed mango, resulting from cross-allergy with mugwort Art v 1 was diagnosed in the patient. Acute urticarial in this case is a manifestation of IgE-mediated food allergy. During in vitro diagnostic procedures we found an elevated concentration of IgE specific to several food allergens (including celery, peppers, carrot, banana, peach, apple, shrimp). The elimination diet removing allergens the patient was allergic to was recommended. Considering the anaphylactic reaction the patient was instructed to carry a rescue set composed of an adrenaline autosyringe, steroids, and antihistamines.

Abstract
Eggplant allergy is rare and most of the previously described reactions were mild. In this case report, we present an interesting case of a 27-year-old male who experienced symptoms of anaphylaxis (shortness of breath, and swelling of the face, lips and tongue, which was followed by hypotension, tachycardia of 140/min and a sudden loss of consciousness) several minutes after eating a dish containing backed eggplant. Previously, the patient had experienced symptoms of allergy after eating different types of food, such as salad and chicken in spices. The symptoms were enhanced by co-factors. They were heterogeneous, ranging from oral symptoms to anaphylactic shock. During the diagnostic pathway, skin prick tests (SPTs) were positive to grass and cat. Prick by prick skin tests were positive for eggplant, both cooked and fresh. In ImmunoCap ISAC, IgE specific to rPhl p 1 (1.7 ISU-E), rCan f 5 (1,2 ISU-E), Fel d 1 (9.6 ISU-E ) and LTPs - nJug r 3 (0.5 ISU-E), rPru p 3 (0.6 ISU-E), rPla a 3 (1.3 ISU-E) were found. Based on the clinical pattern of the disease and the results of component resolved diagnosis, we suspect that this complex case of anaphylaxis may be gathered with LTP syndrome.

Abstract
BACKGROUND Component resolved allergen diagnosis allows for a precise evaluation of the sensitization profiles of patients sensitized to felines and canines. An accurate interpretation of these results allows better insight into the evolution of a given patients sensitizations, and allows for a more precise evaluation of their prognoses. METHODS 70 patients (42 women and 28 men, aged 18-65, with the average of 35.5) with a positive feline or canine allergy diagnosis were included in the research group. 30 patients with a negative allergy diagnosis were included in the control group. The total IgE levels of all patients with allergies as well as their allergen-specific IgE to feline and canine allergens were measured. Specific IgE levels to canine (Can f 1, Can f 2, Can f 3, Can f 5) and feline (Fel d 1, Fel d 2, Fel d 4) allergen components were also measured with the use of the ImmunoCap method. RESULTS Monosensitization for only one canine or feline component was found in 30% of patients. As predicted, the main feline allergen was Fel d 1, which sensitized as many as 93.9% of patients sensitized to felines. Among 65 patients sensitized to at least one feline component, for 30 patients (46.2%) the only sensitizing feline component was Fel d 1. Only 19 patients in that group (63.3%) were not simultaneously sensitized to dogs and 11 (36.7%), the isolated sensitization to feline Fel d 1 notwithstanding, displayed concurrent sensitizations to one of the canine allergen components. Fel d 4 sensitized 49.2% of the research group.64.3% of patients sensitized to canine components had heightened levels of specific IgE to Can f 1. Monosensitization in that group occurred for 32.1% of the patients. Sensitization to Can f 5 was observed among 52.4% of the patients. CONCLUSIONS Concurrent sensitizations to a few allergic components, not only cross-reactive but also originating in different protein families, are a significant problem for patients sensitized to animals.

Abstract
Sunflower seeds are a rare source of allergy, but several cases of occupational allergies to sunflowers have been described. Sunflower allergens on the whole, however, still await precise and systematic description. We present an interesting case of a 40-year-old male patient, admitted to hospital due to shortness of breath and urticaria, both of which appeared shortly after the patient ingested sunflower seeds. Our laryngological examination revealed swelling of the pharynx with retention of saliva and swelling of the mouth and tongue. During diagnostics, 2 months later, we found that skin prick tests were positive to mugwort pollen (12/9 mm), oranges (6/6 mm), egg protein (3/3 mm), and hazelnuts (3/3 mm). A native prick by prick test with sunflower seeds was strongly positive (8/5 mm). Elevated concentrations of specific IgE against weed mix (inc. lenscale, mugwort, ragweed) allergens (1.04 IU/mL), Artemisia vulgaris (1.36 IU/mL), and Artemisia absinthium (0.49 IU/mL) were found. An ImmunoCap ISAC test found an average level of specific IgE against mugwort pollen allergen component Art v 1 - 5,7 ISU-E, indicating an allergy to mugwort pollen and low to medium levels of specific IgE against lipid transfer proteins (LTP) found in walnuts, peanuts, mugwort pollen, and hazelnuts. Through the ISAC inhibition test we proved that sunflower seed allergen extracts contain proteins cross-reactive with patients' IgE specific to Art v 1, Art v 3, and Jug r 3. Based on our results and the clinical pattern of the disease we confirmed that the patient is allergic to mugwort pollen and that he had an anaphylactic reaction as a result of ingesting sunflower seeds. We suspected that hypersensitivity to sunflower LTP and defensin-like proteins, both cross-reactive with mugwort pollen allergens, were the main cause of the patient's anaphylactic reaction.

Abstract
Lymphocytes Th17 and other types of immune system cells produce IL17. By induction of cytokines and chemokines, the IL17 cytokine is involved in mechanisms of allergic reaction with participation of neutrophil granulocytes. It affects activation, recruitment, and migration of neutrophils to the tissues, regulating inflammatory reaction intensity. Excited neutrophils secrete inter alia elastase and reactive oxygen species (ROS)--significant mediators of inflammation process responsible for tissues damage.The aim of the study was to evaluate the concentrations of serum interleukin 17A, serum neutrophil elastase, and ROS production by neutrophils in patients with food allergy.The study included 30 patients with food allergy diagnosed based on interview, clinical symptoms, positive SPT, placebo controlled double-blind oral provocation trial, and the presence of asIgE in blood serum against selected food allergens using fluoro-immuno-enzymatic method FEIA UNICap 100. The control group consisted of 10 healthy volunteers. The concentrations of IL17A were determined in all patients using ELISA method with eBioscience kits, and elastase using BenderMed Systems kits. Chemiluminescence of non-stimulated neutrophils was evaluated using luminol-dependent kinetic method for 40 min on Luminoskan (Labsystems luminometer).The results of serum IL-17A concentrations and the values of chemiluminescence obtained by non-activated neutrophils, as well as elastase concentrations, were higher in patients with food allergic hypersensitivity compared to healthy volunteers.This study demonstrates a significance of IL-17A and activated neutrophil granulocytes in the course of diseases with food allergic hypersensitivity.
