Epidemiological characterization and risk factors of rhinitis and rhinoconjunctivitis among preschool children in Shanghai, China.

BACKGROUND: Previous studies have reported an increasing prevalence of childhood allergic rhinitis in developing countries. There is still a lack of the recent epidemiology of allergic rhinitis among Chinese preschool children. Therefore, this study explored the prevalence of rhinitis symptoms and identified their associations with potential risk factors among children at the age of 3-6 in Shanghai, China. METHODS: Validated International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was adopted to collect information about rhinitis symptoms and potential risk factors. Univariate and multivariate logistic regression analyses were used to assess associations between risk factors and allergic rhinitis and rhinoconjunctivitis. RESULTS: A total of 6183 questionnaires were included in our study. The prevalence of rhinitis ever, current rhinitis, and physician-diagnosed rhinitis were 32.6%, 29.2%, and 14.3%, respectively, while the prevalence of current rhinoconjunctivitis was 11.3%. The higher prevalence was observed in boys than in girls in terms of rhinitis ever, current rhinitis, current rhinoconjunctivitis and doctor-diagnosed rhinitis. Autumn had the highest prevalence among four seasons. In our multivariate logistic regression analyses, history of allergic diseases and paracetamol use in the last year showed positive associations with the increased risk of both current rhinitis and rhinoconjunctivitis, and antibiotic use was an independent significant risk factor only for current rhinitis. Genetic factors, including maternal and paternal rhinitis, asthma, and eczema, were significantly associated with the prevalence of current rhinitis. Similar associations were seen between these factors and current rhinoconjunctivitis, except for paternal eczema. Among environmental factors, smoking exposure at home, heavy truck traffic in home's street, floor heating system were independent risk factors for both current rhinitis and rhinoconjunctivitis in the adjusted model, while cleaning the house less than once a week was only associated with current rhinitis. CONCLUSION: The prevalence of current rhinitis was 29.2% among children aged 3-6 in Shanghai, China. Sex differences and seasonal variations were observed in the prevalence of rhinitis symptoms. The identified risk factors would provide a basis for policy makers and medical experts to take intervention measures to prevent allergic rhinitis and rhinoconjunctivitis.

Conditioned Medium of Human Amniotic Epithelial Cells Alleviates Experimental Allergic Conjunctivitis Mainly by IL-1ra and IL-10.

Allergic conjunctivitis (AC) is the most prevalent form of mucosal allergy, and the conditioned medium (CM) from mesenchymal stem cells has been reported to attenuate some allergic diseases. However, the therapeutic effects of CM from different tissue stem cells (TSC-CM) on allergic diseases have not been tested. Here, we studied the effects of topical administration of different human TSC-CM on experimental AC (EAC) mice. Only human amniotic epithelial cell-CM (AECM) significantly attenuated allergic eye symptoms and reduced the infiltration of immune cells and the levels of local inflammatory factors in the conjunctiva compared to EAC mice. In addition, AECM treatment decreased immunoglobulin E (IgE) release, histamine production, and the hyperpermeability of conjunctival vessels. Protein chip assays revealed that the levels of anti-inflammatory factors, interleukin-1 receptor antagonist (IL-1ra) and IL-10, were higher in AECM compared to other TSC-CM. Furthermore, the anti-allergic effects of AECM on EAC mice were abrogated when neutralized with IL-1ra or IL-10 antibody, and the similar phenomenon was for the activation and function of B cells and mast cells. Together, the present study demonstrated that AECM alleviates EAC symptoms by multiple anti-allergic mechanisms mainly via IL-1ra and IL-10. Such topical AECM therapy may represent a novel and feasible strategy for treating AC.

Associação entre alergia ocular leve e ceratocone em crianças / Association between mild ocular allergy and keratoconus in children

RESUMO Objetivo: Avaliar a possibilidade de alterações precoces sugestivas de ectasia detectáveis no Pentacam em casos sutis de alergia ocular em crianças. Métodos: Análise retrospectiva de 49 prontuários, com paciente de ambos os sexos e idades entre 3 e 14 anos. Do total de crianças estudadas, 31 apresentavam alergia ocular grau 1, e 18 não apresentavam qualquer sinal ou sintoma de alergia ocular, servindo como controles. Avaliaram-se diversos índices do Pentacam. Resultados: Houve associação estatisticamente significativa nas variáveis "Df - variação do mapa da elevação anterior da córnea" e "Pentacam combinado", que podem estar relacionadas com a detecção precoce de ectasia corneana nesses pacientes. Conclusão: Houve relação causal entre a prevalência da alergia ocular e alterações tomográficas na córnea, sugestivas de ceratocone em alguns pacientes provavelmente suscetíveis, podendo ser considerado um fator de risco para essa complicação.

ABSTRACT Objective: To assess if early alterations detected by Pentacam in children suffering from mild ocular allergy are suggestive of ectasia. Methods: A retrospective analysis of 49 medical records of patients of both sexes, aged between 3 and 14 years was performed. In this sample, 31 children suffered from grade I ocular allergy, and 18 presented no signs or symptoms of ocular allergy and comprised the control group. Several Pentacam indexes were evaluated. Results: A statistically significant association was found in the variables "Df - variation of the anterior corneal elevation map" and "combined Pentacam", which can be related to the early detection of corneal ectasia in these patients. Conclusion: There was a causal relation between prevalence of ocular allergy and tomographic alterations on the cornea, suggestive of keratoconus in some probably susceptible patients, which may be considered a risk factor for this complication.

Giant papillary conjunctivitis: A review.

Giant papillary conjunctivitis (GPC), which is characterized by the development of "giant" papillae on the superior tarsal conjunctiva, is a common complication in contact lens wearers. This condition can be associated with excessive mucus production, itching, blurry vision, and diminished contact lens tolerance. Risk factors for GPC include non-disposable lenses, infrequent lens replacement, long wearing time, inadequate lens hygiene, and atopy. Although the exact pathophysiology of GPC remains incompletely understood, it likely develops from the combination of mechanical trauma to the superior tarsal conjunctiva and an immunologic response by the conjunctiva to deposits on the anterior surface of the contact lens. With proper management, GPC has an excellent prognosis. In mild cases, prompt contact lens cessation is sufficient for the resolution of signs and symptoms. For more severe cases, the use of topical anti-histaminic agents is indicated. Uncommonly, topical steroids, non-steroidal anti-inflammatory agents, immunomodulatory medications, or very rarely surgery may be needed. In this review article, we provide a comprehensive review of the available literature on GPC, with an emphasis on recent findings and treatment advances for this common condition.

IL-27 signaling deficiency develops Th17-enhanced Th2-dominant inflammation in murine allergic conjunctivitis model.

BACKGROUND: While most studies focus on pro-allergic cytokines, the protective role of immunosuppressive cytokines in allergic inflammation is not well elucidated. This study was to explore a novel anti-inflammatory role and cellular/molecular mechanism of IL-27 in allergic inflammation. METHODS: A murine model of experimental allergic conjunctivitis (EAC) was induced in BALB/c, C57BL/6 or IL-27Rα-deficient (WSX-1-/- ) mice by short ragweed pollen, with untreated or PBS-treated mice as controls. The serum, eyeballs, conjunctiva, cervical lymph nodes (CLNs) were used for study. Gene expression was determined by RT-qPCR, and protein production and activation were evaluated by immunostaining, ELISA and Western blotting. RESULTS: Typical allergic manifestations and stimulated thymic stromal lymphopoietin (TSLP) signaling and Th2 responses were observed in ocular surface of EAC models in BALB/c and C57BL/6 mice. The decrease of IL-27 at mRNA (IL-27/EBI3) and protein levels were detected in serum, conjunctiva and CLN, as evaluated by RT-qPCR, immunofluorescent staining, ELISA and Western blotting. EAC induced in WSX-1-/- mice showed aggravated allergic signs with higher TSLP-driven Th2-dominant inflammation, accompanied by stimulated Th17 responses, including IL-17A, IL-17F, and transcription factor RORγt. In contrast, Th1 cytokine IFNγ and Treg marker IL-10, with their respective transcription factors T-bet and foxp3, were largely suppressed. Interestingly, imbalanced activation between reduced phosphor (P)-STAT1 and stimulated P-STAT6 were revealed in EAC, especially WSX-1-/- -EAC mice. CONCLUSION: These findings demonstrated a natural protective mechanism by IL-27, of which signaling deficiency develops a Th17-type hyperresponse that further aggravates Th2-dominant allergic inflammation.

Principales aeroalérgenos en rinoconjuntivitis alérgica en la ciudad de Temuco, Chile / Aeroallergens causing rhinoconjunctivitis

Background: Allergic rhinoconjunctivitis (ARC) has a prevalence of 30% in industrialized countries. For an accurate diagnosis and treatment, it is crucial to identify the causative aeroallergen. Aim: To evaluate aeroallergen sensitization in adults with ARC in the city of Temuco, Chile. Patients and Methods: A skin test against the main aeroallergens present in Temuco was carried out in patients aged 15 to 64 years with ARC diagnosed by medical examination and the Score For Allergic Rhinitis. Results: At least one aeroallergen sensitization was present in 234 (62.4%) out of 375 patients. Pollen-sensitized patients were positive mainly for Grasses (44.4%), Plantago (27.8%), Cynodon (26.1%), Sorrel (23.5%), Birch (14.9%), Nothofagus obliqua (13.3%) and Alder (11.1%). Dust mites were the most common non-pollinic sensitizing aeroallergens, including Dermatophagoides pteronyssinus (70.1%) and Dermatophagoides farinae (62.8%). Conclusions: According to our results, skin tests in the city of Temuco should include at least dust mites, pollens of Grasses, Plantago, Cynodon, Sorrel, Birch, Nothofagus obliqua and Alder, because these allergens account for 93% of ARC cases in this city.

[Epidemiological investigation of allergic rhinitis in Ningxia].

Objective: To investigate the epidemiological characteristics of allergic rhinitis (AR) in Ningxia and to analyze its related factors. Methods: From March to September of 2013, a multi-stage and cluster sampling method was used to investigate the diagnosis and treatment of AR in Ningxia Area (3 years and above). Guidelines for diagnosis and treatment of allergic rhinitis (2009, Wuyishan) was used as the basis for the diagnosis of adult AR, while Guidelines for diagnosis and treatment of pediatric allergic rhinitis (2010, Chongqing) was used as the basis for children. SPSS 16.0 software was used to complete the statistical analysis. Results: The total number of questionnaires was 6 000, and the number of effective questionnaire was 5 236, the recovery rate was 87.27%. With 684 cases diagnosed of AR, the prevalence of AR in Ningxia was 13.06% (684/5 236), including 13.40% (325/2 425) of males, 12.77% (359/2 811) of females. The difference was not statistically significant (χ(2)=0.456, P>0.05). There was significant difference in the prevalence between Hui and Han [14.35% (452/3 150) vs 11.12% (232/2 086), χ(2)=11.51, P<0.05]. According to ARIA criteria, persistent AR was 27.63% (189/684), intermittent AR was 72.37% (495/684). The month with highest incidence of AR in Ningxia Area was September, accounting for 71.78% (491/684). The prevalence of urban population was 14.54%, with the prevalence of rural population was 11.90%, and the difference was significant between urban and rural residents (χ(2)=7.90, P<0.05). The age group with highest prevalence rate was 21~30 years old. The main inhalation allergens were mugwort (68.42%), weeds (58.48%) and ragweed (55.56%). The main dietary allergens were wheat flour (14.33%), peanut (13.74%) and walnut kernel (11.99%). The most common complication was allergic conjunctivitis [82.02% (561/684)]. Conclusion: The epidemiology of AR in Ningxia Area is preliminarily understood, which will provide the epidemiological evidence for the prevention and treatment of AR and the formulation of public health policy.

Pollen/TLR4 Innate Immunity Signaling Initiates IL-33/ST2/Th2 Pathways in Allergic Inflammation.

Innate immunity has been extended to respond environmental pathogen other than microbial components. Here we explore a novel pollen/TLR4 innate immunity in allergic inflammation. In experimental allergic conjunctivitis induced by short ragweed (SRW) pollen, typical allergic signs, stimulated IL-33/ST2 signaling and overproduced Th2 cytokine were observed in ocular surface, cervical lymph nodes and isolated CD4+ T cells of BALB/c mice. These clinical, cellular and molecular changes were significantly reduced/eliminated in TLR4 deficient (Tlr4-d) or MyD88 knockout (MyD88-/-) mice. Aqueous SRW extract (SRWe) directly stimulated IL-33 mRNA and protein expression by corneal epithelium and conjunctiva in wild type, but not in Tlr4-d or MyD88-/- mice with topical challenge. Furthermore, SRWe-stimulated IL-33 production was blocked by TLR4 antibody and NF-kB inhibitor in mouse and human corneal epithelial cells. These findings for the first time uncovered a novel mechanism by which SRW pollen initiates TLR4-dependent IL-33/ST2 signaling that triggers Th2-dominant allergic inflammation.

Advances and highlights in mechanisms of allergic disease in 2015.

This review highlights some of the advances in mechanisms of allergic disease, particularly anaphylaxis, including food allergy, drug hypersensitivity, atopic dermatitis (AD), allergic conjunctivitis, and airway diseases. During the last year, a mechanistic advance in food allergy was achieved by focusing on mechanisms of allergen sensitization. Novel biomarkers and treatment for mastocytosis were presented in several studies. Novel therapeutic approaches in the treatment of atopic dermatitis and psoriasis showed that promising supplementation of the infant's diet in the first year of life with immunoactive prebiotics might have a preventive role against early development of AD and that therapeutic approaches to treat AD in children might be best directed to the correction of a TH2/TH1 imbalance. Several studies were published emphasizing the role of the epithelial barrier in patients with allergic diseases. An impaired skin barrier as a cause for sensitization to food allergens in children and its relationship to filaggrin mutations has been an important development. Numerous studies presented new approaches for improvement of epithelial barrier function and novel biologicals used in the treatment of inflammatory skin and eosinophilic diseases. In addition, novel transcription factors and signaling molecules that can develop as new possible therapeutic targets have been reported.

Treatment with olopatadine and naphazoline hydrochloride reduces allergic conjunctivitis in mice through alterations in inflammation, NGF and VEGF.

The aim of the current study was to investigate whether olopatadine and naphazoline hydrochloride reduce allergic conjunctivitis in mice through alterations in inflammation, NGF and VEGF. An allergic conjunctivitis mouse model was established using histamine or an antigen (ovalbumin), following which mice were treated with 1% olopatadine solution and/or 0.2 mg/ml of naphazoline hydrochloride. Histamine or antigen­induced conjunctival vascular hyperpermeability was examined and the levels of inflammatory factors, cytokines, IgE, GMCSF and NGF were analyzed using ELISA in antigen­induced conjunctival vascular hyperpermeability mice. In addition, VEGF protein expression was measured using western blotting in antigen­induced mice. The results indicated that olopatadine and naphazoline hydrochloride significantly suppressed conjunctival dye leakage in mice with histamine or antigen­induced conjunctival vascular hyperpermeability. In addition, treatment with olopatadine and naphazoline hydrochloride was able to reduce the levels of inflammatory factors (TNF­α, IL­1ß and IL­6), cytokines (IFN­Î³ and IL­4), IgE, GMCSF, and NGF in antigen­induced conjunctival vascular hyperpermeability mice. The protein expression levels of VEGF in antigen­induced conjunctival vascular hyperpermeability mice were reduced following treatment with olopatadine and naphazoline hydrochloride. These results suggest that treatment with olopatadine and naphazoline hydrochloride reduces conjunctivitis in mice via effects on inflammation, NGF and VEGF.

[Allergic rhinoconjunctivitis caused by occupational exposure to ginger]. / Allergisk rinokonjunktivitis pga. erhvervsmæssig udsættelse for ingefær.

We present a case report of occupational allergic rhinoconjunctivitis after exposure to dust from ginger-containing herbal medicine. The likelihood of an aetiological connection between exposure and the patient's symptoms was supported by a temporal association, positive specific IgE, positive histamine release test, positive prick test, and positive acoustic rhinometry test. Occupational allergy to ginger has rarely been reported. The cases described - including the one we present - suggest that work-related IgE-mediated allergy is associated with exposure to dry aerosols/dust.

Cytokines in tears during the secondary keratoconjunctival responses induced by allergic reaction in the nasal mucosa.

BACKGROUND: Allergic keratoconjunctivitis (KC) can occur in a primary form due to an allergic reaction taking place in the conjunctivae or in a secondary form induced by nasal allergy. OBJECTIVES: To search for the cytokine changes in tears accompanying the secondary keratoconjunctival response types (SKCR), caused by the nasal allergy. METHODS: In 43 KC patients developing 15 immediate (SIKCR), 16 late (SLKCR) and 12 delayed (SDYKCR) responses to nasal provocation tests with allergens (NPT), the NPTs were repeated with subsequent recording of cytokine concentrations in tears up to 72 h. RESULTS: The SIKCRs (p<0.001), occurring 10-120 min after the NPT, were accompanied by significant changes (p<0.05) of interleukin (IL)-4, IL-6, IL-10, IL-12p70 and granulocyte-macrophage colony-stimulating factor (GM-CSF). The SLKCRs (p<0.01), appearing 5-12 h after the NPT, were associated with significant changes (p<0.05) of IL-3, IL-4, IL-5, IL-8, IL-10, tumor necrosis factor (TNF)-α, GM-CSF and granulocyte colony-stimulating factor. The SDYKCRs (p<0.01), occurring 24-48 h after the NPT, were accompanied by significant changes (p<0.05) of IL-2, IL-8, IL-10, interferon-γ, transforming growth factor-ß and TNF-α. CONCLUSIONS: The particular SKCR types, induced by an allergic reaction in the nasal mucosa, were accompanied by different cytokine profiles in the tears, suggesting involvement of different hypersensitivity mechanisms. These results also stress the diagnostic usefulness of NPTs combined with monitoring of ocular features in KC patients who did not respond satisfactorily to the topical ophthalmological treatment.

[Giant papillary conjunctivitis]. / Gigantopapilläre Konjunktivitis.

Giant papillary conjunctivitis is an inflammation of the conjunctiva, which is associated with immunological-allergic disorders, but is difficult to integrate as a defined type of illness. The deposits of contact lenses are responsible in predisposed wearers. They induce a special immune answer to their biochemical ingredients. In addition, roughness of the superficial corneal layers and the conjunctiva, even without any contact lenses after filtrating glaucoma surgery, leads to mechanically induced papillary formations. In former days these symptoms of building giant papillae were seen mostly in wearers of soft hydrogel contact lenses. Nowadays manufacturers have developed contact lens systems with a variety of material components, with an increase of protein and lipid deposits. In combination with the observed non-compliance of wearers regarding lens exchange and contact lens hygiene, GPC is an issue which should be taken into consideration again.

[The epidemiology of pollen allergy]. / Épidémiologie de l'allergie pollinique.

The prevalence of seasonal allergic rhinitis can be established through surveys performed in a sample of the general population. These surveys are based on a questionnaire, which could lead to an overestimate of prevalence rates, and on measurements of specific IgE, which need to be interpreted in the light of the responses to the questionnaire. Such surveys are few in France and need to be updated. Risk factors for seasonal allergic rhinitis are genetic, epigenetic and environmental. Relationships between exposure to pollen and health can be documented through ecological and panel surveys. Panel surveys may give information on threshold levels and dose-response relationships. In addition to pollen exposure, global warming and air pollutants act as cofactors. Monitoring of both pollen exposure and its health effects should be encouraged and strengthened.

Association between environmental factors and current asthma, rhinoconjunctivitis and eczema symptoms in school-aged children from Oropeza Province--Bolivia: a cross-sectional study.

BACKGROUND: In recent years, the prevalence of asthma, rhinoconjunctivitis and eczema symptoms in childhood has considerably increased in developing countries including Bolivia, possibly due to changes in lifestyle, environmental and domestic factors. This study aimed to assess the association between environmental factors and asthma, rhinoconjuctivitis and eczema symptoms in school-aged children from Oropeza Province in Chuquisaca, Bolivia. METHODS: A cross-sectional study was performed in 2340 children attending the fifth grade in 36 randomly selected elementary schools in Oropeza province. The prevalence of symptoms was determined using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Environmental factors were assessed by the ISAAC environmental questionnaire including questions related to exposure to pets, farm animals, indoor and outdoor pollution, presence of disease vectors at home and precarious household conditions. Generalized linear mixed-effects models were adjusted for age, sex and place of living. RESULTS: Thirty seven percent of children reported that at least one of their parents smoked at home. Wood or coal was used as cooking fuel in 19% of the homes and 29% reported intense truck traffic on the street where they lived. With respect to hygiene conditions, 86% reported exposure to dogs, 59% exposure to cats and 36% regular contact to farm animals. More than one precarious household condition was reported by 8% of children. In the adjusted model exposure to dog (adjusted OR 1.4; CI 95% 1.0-1.9), cat (1.2; 1.0-1.5), farm animals (1.5; 1.2-1.8); intense truck traffic (1.3; 1.0-1.6), parents smoking at home (1.2; 1.0-1.5), presence of disease vectors at home (fourth quartile vs. first quartile: 1.6; 1.2-2.3) and two or more precarious household conditions (1.5; 1.0-2.2) were significantly associated with rhinoconjunctivitis symptoms. The associations were similar for asthma and eczema symptoms; however it did not reach the level of statistical significance for all items. CONCLUSION: Our results support previous findings reported for poor communities especially in Latin America, showing that lower hygiene conditions did not have protective effect against asthma and rhinoconjunctivitis and eczema symptoms.

[Fast onset of action of sublingual immunotherapy in dust mite caused allergic rhinoconjunctivitis].

OBJECTIVE: To investigate whether sublingual immunotherapy(SLIT) can take effect during the early phase in allergic rhinoconjunctivitis. METHOD: Sixty subjects diagnosed as allergic rhinoconjunctivitis were enrolled and divided into the SLIT group and the control group. The daily symptom and medication scores were recorded and analyzed. RESULT: After 4 weeks treatments, the daily symptoms score had significantly reduced in SLIT group(P<0. 05). After 6, 8, 10 weeks treatments, the daily symptoms scores of subjects in the SLIT group had all shown continuous reduction, with no consumption of medication. The comparison between daily symptom score at 4th week and those in 6th week or 8th week or 10th week in the SLIT group had shown no significant difference (all P > 0.05). Whereas, the daily symptoms score and daily medication score in control group had shown changes with fluctuations. The correlation analysis had indicated that the daily medication score in the control group had a significant negative correlation with the daily symptom score (F = 554.9, P < 0.01). No serious adverse events occurred in this study. CONCLUSION: SLIT could take effect in patients with allergic rhinoconjunctivitis sensitive to house dust mite as fast as the 4th week.

Cytological changes in tears during the secondary conjunctival response induced by nasal allergy.

PURPOSE: Allergic conjunctivitis (AC) can be caused by an allergic reaction localised exclusively in the conjunctivae and initiated by direct exposure of conjunctivae to an allergen (primary AC form) or it can be induced secondarily by an allergic reaction occurring primarily in the nose (secondary AC form). OBJECTIVES: To investigate the cellular profiles in tears accompanying the particular types of secondary conjunctival response (SCR). METHODS: In 53 seasonal AC or perennial AC patients developing 53 positive SCRs (17 immediate, 21 late, 15, delayed) and 31 negative responses to the nasal provocation test with allergen (NPT), the NPTs were repeated and supplemented with, cytological examination of the tears. RESULTS: The immediate SCRs (p<0.01), appearing 10-120 min after the NPT, were associated with increased eosinophil and mast cell counts. The late SCRs (p<0.01), occurring 5-12 h, were accompanied by increased eosinophil, neutrophil, basophil and epithelial cell counts. The delayed SCRs (p<0.05), appearing 24-48 h, were associated with increased lymphocyte, neutrophil, monocyte, epithelial and goblet cell counts. CONCLUSIONS: The secondary immediate, late and delayed conjunctival responses, induced by nasal allergy, were associated with different cellular profiles in the tears. The cells, except mast, epithelial and goblet cells, displaying no intracellular changes, had probably migrated from conjunctival capillaries, affected by factors released during the initial nasal allergic reaction, without participating in the allergy processes. In AC patients demonstrating insufficient therapeutic compliance, the role of nasal allergy should be examined.

Pharmacotherapy of rhinitis and rhinosinusitis.

Concerns for the cosmetic surgeon regarding allergic rhinoconjunctivitis and rhinosinusitis include diagnosis, treatment, and assessment of the disease and whether or not the timing or outcome of cosmetic procedures will be affected. In this article, the pharmacotherapy of allergic and nonallergic rhinoconjunctivitis and rhinosinusitis is discussed with emphasis on intranasal steroids, antihistamines, and antibiotics.
