Immunoglobulin Levels

Gastroallergic anisakiasis (GAA) and Anisakis-sensitization-associated chronic urticaria (CU+) differ with respect to specific IgE levels. We hypothesised different immunoglobulin avidities in both entities as well as their dependence on TI and fish consumption. 16 patients with GAA and 17 patients with CU+ were included, and immunoglobulin levels were analysed by CAP (Phadia). IgE and IgG avidity indexes (AvIgE and AvIgG, resp.) were also determined. IgG avidity was higher in GAA than in CU+ (P=0.035), whereas there was a tendency to lower IgE avidity in GAA (P=0.095). When analysing all patients, AvIgG was positively correlated with specific IgE, IgG, and IgG4 as well as total IgE (Rho between 0.66 and 0.71; P<0.002), but AvIgE was negatively correlated with specific IgE (Rho −0.57; P<0.001), specific IgG4 (Rho −0.38; P<0.05), and total IgE (Rho 0.66; P<0.001). In GAA, weekly fish consumption was positively associated with AvIgE (Rho 0.51; P=0.05). A multivariate regression showed that time interval was the main explaining factor for AvIgE in GAA. We could show a differential behaviour of immunoglobulin isotype avidities in both entities and their dependence on fish-eating habits as well as on the time elapsed to the last parasitic episode.

Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA) method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant) were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%), IgE-bound wheezing/asthma (10.8%) and food allergies (7.4%), and to much lesser extent those of allergic rhinitis (3.4%) and urticaria (1.7%). The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005) (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%). Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms.

ABSTRACT Allergic bronchopulmonary aspergillosis (ABPA) is a frequent complication in cystic fibrosis patients. The diagnosis remains difficult and requires a combination of clinical, radiological, biological, and mycological criteria. The aim of this study was to analyze the added value of two recombinant antigens, rAspf4 and rAspf6, associated with the detection of specific IgG; precipitins; total IgE; and Aspergillus fumigatus in sputum for the diagnosis of ABPA. In a retrospective study, we determined the specific IgE responses to these recombinants in 133 sera of 65 cystic fibrosis patients. We selected an average of five serum samples from each of the 17 patients with ABPA (13 proven and 4 probable ABPA) and from 3 patients with Aspergillus bronchitis and rhinosinusitis. One serum sample for the 45 patients without ABPA was tested. The sensitivity of specific IgE detection against rAspf4 calculated per patient (92.3%) was significantly higher (P < 0.05) than that of rAspf6 (53.8%). When rAspf4 IgE detection was associated with anti-Aspergillus IgG enzyme-linked immunosorbent assay (ELISA) and precipitin detection, the sensitivity rose to 100%. The specificities of rAspf4 and rAspf6 IgE detection were 93.7% and 91.6%, respectively. Other diagnostic criteria had slightly lower specificities (87.5% for anti-Aspergillus IgG ELISA, 89.6% for precipitins, 84.4% for total IgE, and 85.0% for positive A. fumigatus culture in sputum). In conclusion, this retrospective study showed the relevance of rAspf4 IgE detection, in combination with other biological markers (Aspergillus IgG ELISA, precipitins, and total IgE), for improving the biological diagnosis of ABPA.

Abstract Background Worldwide, allergy affects more than one billion people, with particularly rising prevalence in industrialised areas. Specifically, young adults appear to be predominantly targeted for an allergy diagnosis. Allergic diseases in pregnancy are mainly pre-existing but could also occur de novo. The immunological changes while pregnant, with increased Th2 lymphocyte activity, can facilitate allergen sensitisation. Objective The aim of this study was to evaluate the pattern of specific IgE (sIgE) sensitisation to common inhalant and food allergens in pregnancy, and assess its relationship to self-reported allergic disease. Methods We assessed 200 pregnant women, aged 20–38 years (mean age = 29 years), participant of ELMA (Epigenetic Hallmark of Maternal Atopy and Diet) study, living in a metropolitan area, with no pregnancy associated metabolic complications, for total IgE and allergen specific IgE to 20 allergens. Results 48% of pregnant women were sensitised to at least one allergen, at a cut-off point of 0.35 kU/L and they were assigned as atopic. However 42% in atopic group were not reporting any allergic disease. The most common inhalant allergens were: pollen (24.5%) and animal dander (23.5%). The most common food allergens were: cow’s milk (5.5%) and apples (4.5%). 7.5% of women reported asthma, 21.5% allergic rhinitis, 11.5% atopic dermatitis and 18.5% food allergy. 8.5% of were taking medication for asthma or allergies. Atopic dermatitis had the highest tendency to become more severe during pregnancy. Total IgE values were significantly higher in atopic women. Conclusions Allergic sensitisation is a common phenomenon in pregnancy. Some sensitisations could be asymptomatic. Further studies should investigate if sensitisation in mothers confers risks for immune alterations in their children.

The Relationship

The Canary Islands are hyperendemic for canine heartworm and the risk of zoonotic infection is high. Additionally, there is evidence of development of allergies due to nematode infections in animals and humans. Since the population of the Canary Islands presents high prevalence of allergic comorbidities, and previous studies have shown a possible relationship between allergies and seropositivity to heartworm, the aim was to evaluate whether exposure to heartworm may contribute to the development of allergies in the human population. First, an epidemiological study was conducted on 248 owners of dogs with/without heartworm infection in the Canary Islands. Secondly, a serological analysis of the presence of total IgE and specific IgE against heartworm was conducted in 66 samples of inhabitants of the Canary Islands. The survey showed that allergic owners had heartworm-positive dogs more frequently (p < 0.01). Of the analyzed human samples, 43.9% were seropositive to heartworm and Wolbachia. Total IgE concentrations were increased in 34.5% seropositive samples and 8.1% seronegative samples. Specific IgE against heartworm was only found in human seropositive samples (17.2%). Contact with heartworm may be a risk factor for the development of allergic diseases, although further studies to elucidate the relationship between heartworm and allergies should be carried out.

Objective: In this study, we: (1) evaluated the correlation between total IgE and the presence of specific IgE; (2) compared the characteristics of patients with positive specific IgE to those with negative specific IgE; and, (3) analyzed the allergic testing results of patients on omalizumab and reported the effect of omalizumab on forced expiratory volume (FEV1) and asthma control test (ACT) results. Methods: Data from patients diagnosed with allergic asthma and seen at Florida Lung, Asthma & Sleep Specialists (FLASS) between January 2016 and June 2019 were analyzed. Parameters evaluated were total IgE, and levels of specific IgE to antigens in the ImmunoCAP test and skin prick test (SPT). Additional parameters for patients on omalizumab therapy for at least 6 months were FEV1, % predicted FEV1 and ACT results. Results: A total of 475 patients (114 males, 361 females) met the inclusion criteria. The mean age was 53 years (range: 17 to 89 years). Of these, 36 patients were not included in the analysis due to incomplete data. Mean total IgE was higher in patients with positive ImmunoCAP results compared to those with negative results (396 KU/L vs. 81.3 KU/L). There was a significant positive correlation between total IgE and levels of positive specific IgE in the ImmunoCAP test (p<0.0001, r=0.36, n=213 patients). The correlation between total IgE and levels of positive allergens in SPT was not significant (p=0.15, n=44 patients) Two positive reactions to allergens were seen in 22% of ImmunoCAP tests and 13% of SPT tests. There was no statistically significant improvement in FEV1 (p=0.097, CI -0.17 to 0.02) and % predicted FEV1 (p=0.109, CI -6.63 to 0.70) in patients who used omalizumab for at least 6 months. There was a statistically significant improvement in ACT scores (p=0.031, CI -4.21 to -0.21) in patients who used omalizumab for at least 6 months. Conclusion: Allergic asthma could be seen in patients who had an absence of specific IgE in ImmunoCAP and a negative reaction to SPT. The benefit of omalizumab therapy is not limited to allergic asthma patients with positive specific IgE.

Special Case

The prevalence of allergic diseases is increasing worldwide. It is estimated that more than 30% of the world population is now affected by one or more allergic conditions and a high proportion of this increase is in young people. The diagnosis of allergy is dependent on a history of symptoms on exposure to an allergen together with the detection of allergen-specific IgE. Accurate diagnosis of allergies opens up therapeutic options. Allergen specific immunotherapy is the only successful disease-modifying therapy for IgE-mediated allergic diseases. New therapeutic strategies have been developed or are currently under clinical trials. Besides new routes of administration, new types of allergens are being developed. The use of adjuvants may amplify the immune response towards tolerance to the antigens. In this review, we analyze different antigen-specific immunotherapies according to administration route, type of antigens and adjuvants, and we address the special case of food allergy.

Different Types

Background and Objectives: Different types of food introduced gradually in the diet will expose children to different food allergens, increasing the chance of developing allergic diseases. The aim of our study was to determine if allergen-specific IgE values can influence, depending on the diet, the prediction of remission of urticaria in children. Materials and Methods: This prospective study was conducted in 132 patients diagnosed over two years with urticaria, admitted to “Sf. Maria” Clinical Pediatric Hospital Iaşi. Total IgE assay was performed by ELISA, and determination of specific serum IgE by the CLA System Quanti Scan method (Innogenetics, Heiden, Germany). Data were gathered and statistical analysis was performed using statistical software SPSS, using descriptive and inferential statistics. Results: The determination of specific IgE to food allergens was performed on a total of 132 cases. The values of specific IgE were positive for one or more food allergens in 84 patients (63.64%). The most common allergens involved were: cow’s milk in 33.3% cases, egg white in 22.6% cases, and hazelnuts in 11.9% cases. The specific IgE values for the different types of food included in our study had a predictive value for disease remission. Conclusions: The determination of specific IgE confirms the presence of a particular food allergen and may have predictive value for the future development of an allergic manifestation.
