Serum IgE, TNF-α and FeNO levels in children with acute attack of bronchial asthma and their correlation with disease severity in Chengdu / 公共卫生与预防医学

Objective To analyze the levels of IgE,TNF-α and FeNO in children with acute attack of bronchial asthma and their correlation with the severity of bronchial asthma, so as to provide theoretical basis for clinical evaluation of bronchial asthma. Methods A total of 547 children with acute bronchial asthma treated in Chengdu Women and Children's Central Hospital from January 2020 to December 2020 were selected and divided into mild group (n=287), moderate group (n=186) and severe group (n=74) according to the severity of their disease. All the children's symptoms were controlled after treatment. The serum IgE, TNF-α and FeNO levels in the experimental group were compared between the acute attack stage and the clinical control stage. Spearman correlation analysis was used to analyze the correlation between the serum IgE, TNF-α and FeNO levels and the severity of the disease. ROC curve of children with bronchial asthma was drawn to analyze the differential diagnosis value of serum IgE, TNF-α and FeNO levels in children with acute bronchial asthma. Results The levels of IgE, TNF-α and FeNO in acute stage were significantly higher than those in clinical control stage (P<0.05). The levels of serum IgE, TNF-α and FeNO in severe group were higher than those in mild and moderate groups significantly (P<0.05). The levels of serum IgE, TNF-α and FeNO in moderate group were higher than those in mild group significantly (P<0.05). Spearman correlation analysis showed that serum IgE, TNF-α and FeNO water were positively correlated with the severity of bronchial asthma (r=0.419 , 0.438 , 0.502 , P<0.05). ROC curve analysis showed that the AUC, sensitivity, accuracy and specificity of serum IgE, TNF-α and FeNO levels combined in diagnosing the severity of bronchial asthma in patients with acute attack was 0.938 (95% CI: 0.912-0.982 ), 83.47%, 92.06%, 94.28%. Conclusion The level of serum IgE, TNF-α and FeNO in children with acute attack of bronchial asthma is closely related to the severity of the disease, and combined detection of the three can be used to evaluate the severity of the disease in children.

A Study on Total Serum IgE Levels and Absolute Eosinophil Count in Allergic Rhinitis Patients

Allergic rhinitis is an IgE mediated hypersensitivity disease of the mucous membrane of nasal airway characterized by sneezing, itching, watery nasal discharge and sensation of nasal obstruction.METHODSThe aim of the study was to evaluate the total serum IgE levels and absolute eosinophil counts in patients with allergic rhinitis, and rhinitis with asthma. In this study, 160 patients of allergic rhinitis attending ENT OPD were clinically examined and investigated with Total Serum IgE levels and absolute eosinophil counts. Statistical analysis was done using SPSS software.RESULTS160 study subjects with signs and symptoms of allergic rhinitis were investigated with total serum IgE levels and absolute eosinophil count. 46.25% were males and 53.75% were females. The patients included in the study were aged 10-60 years. Seasonal symptoms were observed in 44% of patients while perennial symptoms were experienced by 56% of the patients. As per ARIA classification, 66.3% had mild, 6.9% had moderate and 26.9% had severe allergic rhinitis. Bronchial asthma was found to be the most common comorbidity present in 13% of subjects, associated sinonasal polyps which was present in 13.8%. 71.9% had raised Total Serum IgE levels and eosinophilia was present in 59.4%. A significant relationship exists between total IgE levels and eosinophilia in patients with allergic rhinitis.CONCLUSIONSAllergic rhinitis is an IgE mediated inflammatory disease and raised total serum IgE levels and raised absolute eosinophil count in study subjects with clinical signs and symptoms of rhinitis are likely to correlate with allergic aetiology.

Correlation between polymorphism of-152G/A and 7488T/C at IL-17 gene and levels of total serum IgE among 224 children with Asthma in Guiyang / 中华微生物学和免疫学杂志

Objective To investigate the influences of interleukin 17A gene promoter -152G/A (IL-17A -152G/A) and interleukin 17F gene exon 7488 T/C (IL-17F 7488T/C) single nucleotide poly-morphisms on children bronchial asthma and serum total IgE ( TIgE) levels. Methods Genotype distribu-tion of IL-17A-152G/A and IL-17F 7488T/C in 224 children with asthma and 150 healthy subjects was de-tected by polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) analysis. Some samples were selected for PCR product sequencing and verification. IMMAGE800 specific protein analyzer from the Beckman Coulter test system was used to automatically detect serum TIgE levels in all subjects. Re-sults Three genotypes of AA, AG and GG were detected at IL-17A -152G/A locus in both asthma and control groups. Differences in genotype frequency distribution were statistically significant between the two groups (P<0. 05). Subjects carrying the variant allele A at IL-17A-152G/A locus were more likely to have asthma than those without (P<0. 05). Three genotypes of TT, TC and CC were detected at IL-17F 7488T/C locus in both asthma and control groups, but differences in the frequency distribution of genotype and al-lele were statistically significant between the two groups (P<0. 05). There was a significant difference in se-rum TIgE levels between asthma and control groups (P<0. 05). In asthma group, patients of AA genotype at IL-17A -152G/A locus had higher serum TIgE levels than those of AG genotype (P=0. 001) and GG geno-type (P=0. 001). No significant difference in serum TIgE levels was found among healthy subjects of the three genotypes in control group. No significant difference in serum TIgE levels was observed among the sub-jects of TT, TC and CC genotypes at IL-17F 7488T/C locus in asthma or control group (P>0. 05). Conclu-sion IL-17 gene polymorphism was correlated with the incidence of asthma in children in Guiyang area. IL-17A -152G/A polymorphism was an important candidate gene for asthma in Guiyang area and the variant al-lele A at -152G/A locus was correlated with increased serum TIgE levels. IL-17F 7488T/C polymorphism was also an important candidate gene for asthma in Guiyang. Children carrying the variant allele C at IL-17F 7488T/C locus showed a lower risk for asthma in Guiyang. IL-17F 7488T/C polymorphism had no influence on serum TIgE levels.

A Significance of High Levels of Total Serum IgE in Herpes Zoster / 대한피부과학회지

BACKGROUD: Herpes zoster is caused by the reactivation of varicella zoster virus. Many factors are involved in the reactivation of viruses, but most of them are unknown, except for immunosuppression and old age. A relationship between an increased level of total serum IgE and viral infection has been observed in a few previous studies. OBJECTIVE: The purpose of this study was to evaluate the quantitative changes, as well as the role of the total serum IgE, in patients suffering with herpes zoster. METHODS: We retrospectively reviewed the medical records and laboratory data of 205 patients with herpes zoster. We evaluated the clinical findings such as the affected dermatomes, the duration of illness and the persistence of herpes zoster-associated pain. The relationships of the clinical findings and the level of total serum IgE, which was measured by competitive chemiluminescence immunoassay, were also evaluated. RESULTS: The level of total serum IgE was elevated in 95 (46.3%) of 205 patients with herpes zoster and who did not have any medical history that would influence the level of total serum IgE. The amount of elevation of the total serum IgE was higher in the younger patient group than that in the older patient group. However, there were no statistically significant relationships between the level of total serum IgE and the clinical features. CONCLUSION: The level of total serum IgE in patients with herpes zoster was increased to more than the normal level. This may contribute to an overt defect of the cellular immune system in patients with herpes zoster.

Correlation Between the Total Serum IgE Level of Asthmatic Diseases in Infants and the Development of Asthma / 药物流行病学杂志

Objective:To study the total serum IgE level of infant's asthmatic diseases in acute attacks and its effect on the development of wheezing.Method:The serum IgE levels of 964 children(younger than two years old)diag- nosed as asthmatic bronchitis or bronehiolitis were measured by immune dispersion nephelometer.Result:78.9% childrens had high E levels(females took up 25.9% and males,74.1%),asthmatic bronchitis accounted for 92.3% of the total and bronehiolitis,60.3%.Of the 328 infants involved in our research,76 were diagnosed as asthma at last,which accoun- ted for 23.2%.Conclusion:78.9% infants had a high level of IgE in an acute phase.There was a prominent relativity be- tween IgE and the development of asthma.The increased IgE level of asthmatic bronchitis was obviously higher than that of the bronchiolitis.There appeared to be a connection between the IgE level and the occurrence of asthmatic bronchitis to- gether with the development of asthma.

Clinical significance of serum IgE / 소아과

Many previous studies have proved that human allergic disease resulted from the formation of antibodies belonging to a unique immunoglobulin isotype termed immunoglobulin E (IgE). Most of IgE- producing plasma cells are found in the lymphoid tissue associated with the gastrointestinal and respiratory tracts. IgE may be found free in the mucosal secretions of these tissues, bound to local mast cells, or distributed by the systemic circulation to mast cells and basophils throughout the body. Total serum IgE concentrations tend to be higher in allergic adults and children compared with non-allergic individuals, but the value of total serum IgE as a screening test for allergic disease is limited. Total serum IgE levels are related to the probability of an individual having detectable allergen-specific IgE. Allergen-specific IgE concentrations vary with a person's age, the degree and duration of the recent allergen or cross-reactive allergen exposure. The value of quantitative assays for allergen-specific IgE has been suggested in recent studies. Serum IgE increases in many non-allergic diseases, including infectious and parasitic diseases. The IgE changes appear to be specific to the infectious agents, whereas non-specific in other diseases. The increased serum IgE in some of these conditions probably results from alterations in immune function. This review summarizes the clinical significance of total and allergen-specific IgE examinations in allergic diseases.

A Case of Job's Syndrome / 대한피부과학회지

The Job's syndrome is a relatively rare primary immunodeficiency disorder characterized by recurrent staphylococcal infection and abscess formation, defective neutrophil chemotaxis, and markedly elevated serum IgE level. Clinical features are atopiclike dermatitis, furunculosis, paronychia, pulmonary bacterial pneumonia etc. We reported a case of Job's syndrome in a 12-year-old girl who had recurrent pneumonia, scaly pruritic dermatitis, fissured tongue, and nail dystrophy with elevated serum IgE level.

The Relationship between Total Serum IgE, Allergen-Specific IgE, and Skin Prick Test in Children with Atopic Asthma

PURPOSE: Skin prick test and determination of allergen-specific IgE antibodies in serum are methods commonly used to diagnose allergies. Several studies indicate that skin test and specific IgE have roughly the same diagnostic precision, although discrepancies exist. The objective of this study was to evaluate the influence of total serum IgE on the relation between skin prick test and allergen-specific IgE antibody. METHODS: We performed skin prick tests using 14 major inhalant allergens and measured total IgE and specific IgE for two major allergens [Dermatophagoides farinae(D.f.) and Dermatophagoides pteronyssinus (D.p.)] in serum of 230 children with atopic asthma. RESULTS: Positivity of skin prick test was 92.2% for D.f., 89.6% for D.p., and 22.6% for cockroach. Allergen/Histamine(A/H) ratio and allergen-specific IgE score showed a positive correlation for D.f.(r=0.39, P<0.01), and for D.p.(r=0.38, P<0.01). Total serum IgE and allergen-specific antibody score showed a positive correlation for D.f.(r=0.50, P<0.01), and for D.p.(r=0.53, P<0.01). There was no correlation between total serum IgE and A/H ratio on skin prick test for the two allergens. However, total serum IgE had the tendency to increase according to the number of positive allergens on skin prick test. At each level of A/H ratio for D.f. and D.p. on skin prick test, patients with high total IgE had higher antigen-specific IgE scores than patients with low total IgE. CONCLUSION: Our results show that the relationship between skin prick test and antigen-specific IgE was influenced by the level of serum total IgE. This indicates that the level of serum total IgE should be taken into account when skin prick test and allergen-specific IgE are compared.

PURPOSE: The tests of Serum IgE and allergen specific antibodies are important for screening and diagnosis of allergic disease. This study was conducted find out the distributions of allergic diseases, level of IgE, and usual allergen specific antibodies in healthy well-being preschool childrenin Inchon city. METHODS: We gained the level of serum IgE and RAST (radioallergosorbent test : D. pteronyssinus, D. farinae, Egg white and Cow milk) for 274 (Male 130, Female 144) preschool children in Inchon city during January through June in 1997. The history of allergic diseases (allergic asthma, allergic rhinitis, atopic dermatitis, food allergy and urticaria) was taken by each children's parent over telephone interviews. The personal computer SAS program was used for data analysis. RESULTS: 1) The 274 preschoolers (female 144, male 130 F:M=1:0.9) were composed of 74 (female 44, male 30) 3 year-old, 99 (female 52, male 47) 4 year-old, and 101 (female 48, male 53) 5 year-old children. 2) 30.1% of the children were with history of allergic diseases. 3) The mean and standard deviation of serum IgE levels were 215.8+/-171.0 IU/mL with a history of allergic diseases and 60.4+/-73.2 IU/mL without a history of allergic diseases for 3 year-old; 237.0+/-233.5 IU/mL and 48.5+/-74.4 IU/mL for 4 year-old; and 223.6+/-247.5 IU/ml and 45.2+/-41.9 IU/mL for 5 year-old children (P<0.001), respectively. 4) The rate of positive RAST (D. pteronyssinus, Dp) was 66.7% with a history of allergic diseases and 2.6% without a history of allergic diseases for 3 year-old girls, and 41.7% and 5.6% for 3 year-old boys; 58.3% and 2.5% for 4 year-old girls, and 53.8% and 2.9% for 4 year-old boys; and 61.1% and 3.3% for 5 year-old girls, and 54.5% and 0.0% for 5 year-old boys (P<0.001), respectively. 5) The rate of positive RAST (D. farinae, Df) was 66.7% with a history of allergic diseases and 0.0% without a history of allergic diseases for 3 year-old girls, and 16.7% and 0.0% for 3 year-old boys; 50.0% and 0.0% for 4 year-old girls, and 46.2% and 5.9%, for 4 year-old boys; and 55.6% and 3.3% for 5 year-old girls, and 54.5% and 0.0% for 5 year-old boys (P<0.001), respectively. 6) The rate of positive RAST (Egg white, F1) was 66.7% with a history of allergic diseases and 21.1% without a history of allergic diseases for 3 year-old girls, and 66.7% and 38.9% for 3 year-old boys; 75.0% and 15.0% for 4 year-old girls, and 46.2% and 5.9% for 4 year-old boys; and 38.9% and 13.3% for 5 year-old girls, and 50.0% and 19.4% for 5 year-old boys (P<0.001), respectovely. 7) The rate of positive RAST (Cow milk F2) was 0.0% for 3, 4 and 5 year-old and boys both with and without a history of allergic diseases. CONCLUSION: We conclude that serum IgE level and RAST (Dp, Df, F1) are important screening methods for allergic disease of preschool children, and milk allergy is little over 3 year-old children in Inchon. Further studies will be needed.

Linkage analysis between gene marker of chromosome 11q13 and total serum IgE level in sib - pairs with probands of asthmatic children / 천식및알레르기

BACKGROUND: It is known that total serum IgE levels closely corrleate with prevaience of asthma regardless of atopic status. Although heredity is reported to be important in expression of total serum IgE in twin studies, genetic factor controlling this phenotype is controversial. Objective .' To evaluate whether genetic factor in chromosome 1 1q13 may control the expression of tatal serum IgE level, linkage analysis between this phenotype and gene marker of chromosome 11q13 was investigated. MATERIAL AND METHOD: Total serum IgE level and the genotype of chromosome 11q13 with microsatellite marker (D11597) was determined in 73 probands of asthmatic chiMren and 76 their sibs. Statistical significance of linkage was evaluated by affected and quantitative trait locus (QTL) sib-pair analysis. RESULT: In 20 affected sib-pairs with total serum IgE level higher than 305 IU/ml (geometric mean plus two folds SD in 53 normal controls), two D11S97 alleles were shared by ten sib-pairs, one allele by nine sib-pairs, and no allele by one sib-pairs. Sharing rate of the alleles in affect,ed sib-pairs, was 72.5%, which indicates linkage of the phenotype and genotype (x=4. 27, p=0.03). In 35 sib-pairs with total serum IgE level higher than 170 IU/ml (geometric mean plus one fold SD in 53 normal controls), two D11S97 alleles were shared by 16 sib-pairs, one allele by 15 sib-pairs, and no allele by four sib-pairs. The shar ing rate of the alleles in affected sibpairs, was 67.1%, which indicates linkage of the phenotype and the genotype(x=4. 24, p=0.03). Difference of geometric value of total serum IgE levels between probands and their sibs wa,s smaller in 32 sib-pairs sharing two alleles than in 32 those sharing one allele and 12 those with no identical allele (0.45+0.07 vs. 0.52+0.07 vs. 0.89 +0.21). CONCLUSION: The expression of total serum IgE level was linked to gene marker of chromosome 11q13.

Serum IgE Standardized for Age in Korean Children and Its Diagnostic Reliability in Childhood Asthma

PURPOSE: IgE was identified by Ishizaka as an antibody that is reacted at Type I hypersensitivity reaction, and has been used in the diagnosis of allergic disease and the differential diagnosis of extrinsic and intrinsic asthma. But there was some confusing in the diagnosis because of the broad range of measured serum IgE. Recently it was reported that serum IgE should be standardized for area and age to give the diagnostic reliability. METHODS: We measured serum IgE in 512 Korean children admitted at Ewha Woman University Mokdong Hospital between March 1991 and March 1994 and studied the relationship between asthma and serum IgE standardized for age in Korean children. RESULTS: 1) The geometric mean of serum IgE in non - allergic children and asthma were increased gradually according to age. The ranges of measured IgE in each group were overlapped in some part. 2) Log IgE increased by age similarly in asthma and non - allergic children, but was higher in asthma children than non - allergic children. Z scores of log IgE in asthma children increased by age, but those in non - allergic children was not changed by age. 3) Log IgE in male was not significantly different to that of female (p>0.05). 4) Incidence of asthma increased by increasing of Z score of log IgE standardized for age(p<0.05). 5) The normal range of serum IgE standardized for age was presented. Asthma was absent in children below the lowest normal IgE level (log IgE-1.5SD). CONCLUSIONS: Serum IgE if standardized by age, would be much valuable for the diagnosis of asthma in children.

A case of hyperimmunoglobuline E syndrome

The hyperimmunoglobulin E syndrome is a primary immunodificiency disorder characterized by recurrent staphylococcal infections and markedly elevated serum IgE level. Clinical features are coarse face and severe infections of the skin-furunculosis or chronically pruritic dermatitis and sinopulmonary tract infection from infancy by coagulase positive Staphylococcus aureus, or Candida albicans etc. The patients's serum IgE level is elevated but the basic immunologic pathogenesis not fully understood. We have experienced a case of hyperimmunoglobulin E syndrome in a 26/12-year-old who had suffered from recurrent staphylococcal pneumonias and abscesses and chronically pruritic dermatitis from 1 month of age with elevated serum IgE level. A brief review of the related literature is presented.

The results were as follows . 1. The median value of total serum IgE level of each age group in patients with atopic dermatitis distributed from 56.5 IU/@Ll to 660It.J/C. The distributions of the median value of total serum IgE levels of total patients with atopic dermatitis, total male patients with atopic dermatitis, and total female patients with atopic dermatitis were 185 IU/C, 220 IUj'@C, and 165 IUj'C. There was no statistical significance of median value of total serum IgE level between mole patients and female patients. 2. The 95% and 99% lower confidence limit(one-sided) of total serum IgE level of ea.ch age group in patients with atopic dermatitis distributed from 32.6 IU /n4 to 287IU/v4 and from 31 IU/m0 to 202 IU4. The 95% lower confidence limit (one-sided) of total serum IgE level of total patients with atopic dermatitis, tatal male patients with atopic dermatitis, and. total female patients with atopic dermatitis were 170 II.J/m0, 185 IU,m/l, and 133 IUm/l. The 99% lower confidence limit.(one-sided) of total serum IgE level of total patient with atopic dermatitis, total male patient with atopic dermatitis, and total female patients with atopic dermatitis were 165 IU/ml, 180 IU/ml, and 125 IU/ml.

IgE and In Vivo Delayed Hypersensitivity to the Recall Antigens in Atopic Dermatitis and Their Relationship / 대한피부과학회지

We measured serum 1gE by using IgE 'Eiken' radioirnrnunoassay Kit and delayed cutaneous hypersensitivity responsiveness by the Multitest CMI Kit (Institut Merieux) that simultaneously administrates 7 standardized recall antigens(tetanus, diphtheria, streptococcus, tuberculin, candida, trichophyton, proteus) and 70% W/V glycerin diluent control by multiple prick puncture. We studied 40 cases comprising 20 patients with atopic dermatitis (AD) and 20 healthy children as control. The results were obtained as follows; 1) The mean serum level of IgE in AD(63.3+/-395.2 1U/ml) was higher than in control(155.6+/-67.1IU/ml) (p<0.0l), but the intensity of reaction (IR) & rate of reaction (RR) in AD (l.34+/-1.06, 0.38+/-0.23) was not significantly decreased than in control (1.70+/-0.87,0.44+/-0.16). 2) 1n both AD & control group, tuberculin showed highest IR R RR. 3) Anergic state was found in only one patient with disseminated cutaneous lesions Sc 4) serum IgE, but rate of hypoergy was significantly increased in AD(65%) than in control (30%) (p<0.05). 4) Serum IgE was not statistically correlated with IR and RR, but IR was statistically correlated with RR (p<0.001, r=0.9504). 5) IgE level in severe AD (generalized skin lesion) was significantly increased than in both mild AD 8c control group (p<0. 001). but IR & RR were not statistically correlated with disease severity.

Serum IgE levels in 48 patients with scabies were measured by enzyme-linked immunosorbent a.ssay(ELISA) to evaluate the relationship between the scabies and serum IgE. A group of 44 healthy persons was taken as a controls. The results were summarized as follows: In children group(p 15 year-old) of the scabies, serum IgE level was 446 3 +267.2 IU/ml and significantly elevated than in controls, 126, 3 175, 4 IU/rnl, In adult group(over 16 year-old), serum IgE levels of the scabies and controls were 506. 4 + 581. 8 IU/ml, 435, 5+ 548, 8 lU/rnl respetively, and there was no significant difference between them. 2) There were no statistical correlations between the serum IgE levels and intensity of pruritus, duration of illness, number of skin lesions or number of circu1ating eosinophils in patients with scabies.
