Abstract Background and Aims IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis characterized by impaired immunological tolerance. One of possible trigger factors for IgAN initiation and development are allergens which have been described to form IgA complexes deposited in the mesangium. Previous studies reported that serum immunoglobulin class E (IgE) levels are elevated and suggested as a prognostic indicator in glomerular diseases. However, mechanisms of IgE/IgG4-mediated allergic reactions involvement in IgAN as well as specific allergens and their clinical significance have poorly been investigated. The aim of the study was to assess the total serum IgE and IgG4 level and to determine the allergoprofile in IgAN patients. Method The peripheral blood was obtained from 21 IgAN patients (aged of 32.0 (27.0 ÷ 36.0) y.o., male/female ratio as 14/7) and 18 donors (aged of 38.0 (30.0 ÷ 46.0) y.o., male/female ratio as 10/8). IgAN diagnosis was confirmed in patients’ biopsy materials according to the Oxford classification (MEST-C score). The concentrations of total IgE and IgG4 were determined using «IgE total-ELISA-BEST» kit («Vector-Best», RF) and «Human IgG4 Platinum ELISA» kit («eBioscience», Austria)». Allergen-specific IgE to 55 inhalation (domestic, epidermal, fungal, plant) or food allergens were measured using «EUROLINE Atopy Screen IgE» immunoblot kit («Euroimmun», Germany). Statistical analysis was done in Statistica 8.0. Results The increased level of total IgE (in 47,4% of cases) but not IgG4 was established in sera of IgAN patients as compared to donors (p=0.004). Moreover, proteinuria was lower in IgAN patients with a high IgE level as compared to normal one (610 (220 ÷ 910) mg/day vs 1545 (600 ÷ 2200) mg/day, p=0.01) as well as there were no any crescent formation. The investigation of allergen-specific IgE in IgAN patients revealed a strong positive reaction to dust mite allergens of Dermatophagoides pter. (22,75 (16,72 ÷ 35,69) IU/ml – in 29% of cases) and Dermatophagoides farinae (38,24 (12,19 ÷ 65,88) IU/ml – in 43% of cases) correlated with the total IgE (R=0,57, p=0,03) and IgM (R=0,54, p=0,04). The more concentration of specific IgE to dust mite allergens was the lower the severity of segmental glomerulosclerosis (R= -0.55, p=0.04), crescent formation (R= -0.56, p=0.03), proteinuria (R= -0.65, p=0.01) and haematuria (R = -0.55, p = 0.04) were reported. A weak positive reaction was established to other domestic (house dust, honey bee venom, common wasp venom, cockroach), epidermal (cat), plant (sweet vernal grass, orchard grass, timothy grass, cultivated rye, alder, birch, hazel, oak, common ragweed, mugwort, plantain) and food (carrot, sesame, hazelnut, apple) allergens in 9–18% of IgAN patients. Conclusion The prevailing of specific IgE to dust mite allergens of Dermatophagoides pter. and Dermatophagoides farinae but not to food or plant allergens was determined in IgAN patients. The obtained data demonstrated that IgAN pathogenesis in patients with latent sensibilization to dust mite allergens is characterized by a milder disease course what allows to identify this cohort as possible secondary form of IgAN.

Indian Scenario

Background: IgA nephropathy (IgAN) is most common primary glomerulopathy. There are variations in prevalence of IgAN and its clinical features in different studies from India. Aim: To summarize overall scenario of IgAN in India. Methods: In this systematic review, studies related to IgAN and related renal disease were included. Data searched were PubMed, EMBASE, Google scholar, and Cochrane Database from inception to 31st January 2019. Results: Total 49 studies (N=2480) were included: 21studies (N=2309) of primary IgAN; 19 studies (N=21) of Secondary IgAN; four studies (N=133) of IgA vasculitis nephropathy (IgAVN); and five studies (N=17) of IgA dominant nephropathy (IgADN). Prevalence of IgAN was 16.5% in India. Age of affected persons was ranging from 27.2±16.7 to 48.6±21.3 years . Male female ratio was 1.8:1. Clinical features of Primary IgAN, IgAVN, IgADN & Secondary IgAN were microscopic hematuria (49.6%, 44.4%, 15.6% & 59.5%), macroscopic hematuria (5.1%, 0.4%,40.9%,& 35.7%), Subnephrotic proteinuria (42.1%, 29.4%, 23.2%, & 52.3%), nephrotic proteinuria (16.0%, 4.4%, 76.8%,& 47.6%), and hypertension (25.8%,18.3%, 35.5%,& 47.6%).. The 24 hours proteinuria was ranging from 2.6±1.5 to 4.7±2.3 gm/day and serum creatinine (mg/dl) was ranging from 0.9±0 to 3.5±3.9 mg/dl. Histolomorphologically, all type of IgAN showed mesangial hypercellularity and Immunofluorescence revealed IgA deposition. Conclusion: The overall prevalence of primary IgAN in India was 16.5%. The subnephrotic proteinuria and microscopic hematuria were common clinical features. Keywords: IgA Nephropathy; histomorphology; prevalence; India.

Abstract Background Oral mite anaphylaxis (OMA) is a condition characterized by severe allergic reactions after ingesting food containing dust mite-contaminated flour. Physical exertion is recognized as a common trigger factor inducing anaphylaxis. The association of OMA with exercise-induced anaphylaxis has rarely been reported. Case presentation We report a 29-year-old Thai woman who had dust mite ingestion-associated, exercise-induced anaphylaxis who tolerated the same bag of contaminated flour without exercise. A sample of contaminated cooking flour was examined under a light microscope. Living mites, Dermatophagoides farinae, were detected by a medical entomologist based on the morphology. We performed skin test to both mite-contaminated and newly opened Gogi® cooking flour, common aeroallergens, food allergens, and all other ingredients in the fried coconut rice cake 5 weeks after the anaphylactic episode. Specific IgE tests, using ImmunoCAP were also performed. Conclusions Dust mite ingestion-associated, exercise-induced anaphylaxis may be misdiagnosed as wheat-dependent exercise-induced anaphylaxis and should be suspected in patients with anaphylaxis linked to food intake and exercise, but who have no apparent evidence to the index food ingredients on allergy workup.

We measured the number of airborne, viable fungi and house dust mite (HDM) allergen levels in the homes of a group of asthmatic children. Blood samples were drawn and the amounts of total and specific serum IgE were determined. The association between the number of fungal colonies, dust mite allergen exposure, and specific and total IgE was evaluated. The number of viable airborne fungi was high (20 543 CFU/m) in those investigated houses.Der p1concentrations on child's mattress exceeding 2μg/g were found in 78.6% of the houses. A quantitative dose-response relationship was demonstrated between the exposure to viable, airborne molds and the amount of total IgE (r=0.4399andP=.0249) and the level was further increased in children with coexposure to viable fungi and HDM.

BACKGROUND: IgE may be considered the hallmark of allergic disorders. It is easily detected in serum and can be measured as total IgE and as allergen-specific IgE. In fact, the serum IgE assay is used to diagnose an allergy.AIM: The aim of this study is to evaluate, investigate and present the distribution of total serum IgE levels, determined with UniCap system, in food-allergy suspected patients in a Republic of Macedonia.MATERIAL AND METHODS: In this study we analyzed retrospectively 8898 consecutive patients that were admitted for allergy testing at the Institute of Immunobiology and Human Genetics during the ten year period between 01.01.2001 and 01.01.2011. Total IgE levels in patient sera were detected with the in vitro system UniCAP100 (Pharmacia, Uppsala, Sweden).RESULTS: When we analyzed the number of patients according to the total IgE groups, we noted that most of the patients have normal levels of total IgE in serum. However, we also discovered a group of patients with elevated levels of total IgE that are greater than 200 kU/L. The average concentration of total serum IgE is higher in women in the age group 6 (6-7 years), followed by a steep decrease in the age group 9 (9-10 years), and after that the average concentrations of total IgE were mostly constant with the exception of a partial increase in the age group 21 (65-69 years). For men, the average serum concentrations of total IgE were highest in the age group of 6 (6-7 years), which was significantly higher than the average concentrations of total IgE in all other age groups.CONCLUSION: The large number of enrolled patients, a particular strength of this study, revealed that average concentrations of total IgE in men are higher than in women and that total IgE did not decrease with age. On the contrary, increased total IgE levels were found in patients aged 65 and 69 of both genders. We continue our work with analyses of the specific IgE antibodies values toward food and the correlation with total IgE values.

Asthma is a common problem that affects about 20 million peoples in India and can be often under-diagnosed or misdiagnosed. It can be allergic or non-allergic though the former type is more common and prevalent. Allergic asthma can be triggered by many allergens and house dust mites (HDM) are one of the common indoor allergens. The present study emphasizes the significance of house dust mites in allergic asthmatic subjects which is based on 115 asthmatic subjects in Punjab, India. For the quantification and the estimation of total serum Immunoglobulin E and HDM specific IgE, a mixture of 14 allergens and a mixture of two mite allergens viz. Dermatophagoides pteronyssinus and D. farinae were used respectively. Total and specific IgE levels were detected on ImmunoCAP Phadia 100. A statistically significant correlation between total and HDM specific IgE levels of 115 asthmatic subjects was found as compared to control group of 30 non-allergic individuals. The specific IgE levels of 54.78% subjects against the allergen of two mite species were found to be positive. Dust samples were taken from various localities of the houses to identify the diversity of house dust mites which were responsible for allergic asthma. Five common house dust mite species viz. D. pteronyssinus Trouessart, D. farinae Hughes, D. microceras Griffiths and Cunnington, D. aureliani Fain and Euroglyphus maynei Cooreman were identified from the dust. The present study observed that total IgE levels were higher with higher specific IgE levels against the mixture of two mite allergens viz. D. pteronyssinus and D. farinae in the blood serum.  D. pteronyssinus was the most abundant and prevalent mite species followed by D. farinae. Therefore, present study concluded that HDM specific IgE levels against the mite allergen of D. pteronyssinus and D. farinae in the serum of allergic asthmatic subjects were found to be higher because of the higher prevalence of these two mites (D. pteronyssinus i.e. 69.80% and D. farinae i.e. 20.72%) in the house of allergic asthmatic subjects as compared to other identified mites.

Abstract Background: Thymoma is often associated with a series of paraneoplastic syndromes. Among them, thymoma-related nephrotic syndrome is much rare.Methods: This retrospective study collected data from patients with thymoma and renal involvement in Xiangya Hospital, Central South University in a period of 5 years to investigate the clinical characteristics of thymoma-associated nephrotic syndrome.Results: Seven patients were studied (age: 51.1±21.4 years old; male/female ratio: 5/2). Among them, thymic pathology revealed 2 cases of type A and 1 case of type B3, myasthenia gravis (MG) was found in 1 out of 7 cases. Renal pathology showed 2 cases of FSGS and 1 case of IgA nephropathy. 2 out of 7 cases who received combined therapy of steroid and immunosuppressive drugs achieved complete remission. Despite 3 out of 7 cases received surgical excision of thymoma, 2 of them experienced treatment failure in nephrotic syndrome.Conclusions: nephrotic syndrome can be associated with thymoma. The FSGS is the most frequent thymoma-associated glomerular lesion in this study. IgA nephropathy may be another pathological type in thymoma-associated NS. Despite after surgical excision, long treatment periods with high dosage of steroid combined with immunosuppressants were needed to achieve complete remission.

ABSTRACT One hypothesis for the decreased rates of atopy observed among helminth-infected individuals is that parasite-induced polyclonal immunoglobulin E (IgE) outcompetes allergen-specific IgE for FcεRI binding on basophils and mast cells. In experiments with fresh blood drawn from filaria-infected patients, we found no association between ratios of polyclonal to Brugia malayi antigen (BmAg)-specific IgE (range, 14:1 to 388:1) and basophil responses to BmAg as measured by histamine release. Using serum samples from a filaria-infected patient who also had dust mite (Dermatophagoides pteronyssinus)-specific IgE antibodies from time points with various ratios of polyclonal to D. pteronyssinus-specific IgE (16:1 to 86:1), we demonstrated that increased ratios of polyclonal to D. pteronyssinus-specific IgE did not attenuate basophil sensitization as measured by D. pteronyssinus-specific histamine release. Suppression of histamine release was likely not observed in either of these sets of experiments because polyclonal to antigen-specific IgE ratios were not sufficiently high, as concurrent passive sensitization of basophil experiments required ratios of polyclonal to antigen-specific IgE of greater than 500:1 to suppress basophil histamine release. Further, the intensity of IgE staining in basophil populations from 20 patients with active filaria infections correlated strongly with total serum IgE levels (rho = 0.698; P = 0.0024) with no plateau in intensity of IgE staining, even though some patients had total IgE levels of greater than 10,000 ng/ml. Our data therefore suggest that in helminth infections (and in filarial infections in particular), the ratios of polyclonal to allergen-specific IgE rarely reach those levels necessary to inhibit allergen-specific IgE-FcεRI binding and to suppress allergen-induced degranulation of mast cells and basophils.
