Evaluation of the treatment strategy for complicated allergic rhinitis.

OBJECTIVE: Aim: To carry out a comprehensive evaluation of treatment modification for patients with seasonal allergic rhinitis (SAR) complicated by anxiety-neurotic disorders. PATIENTS AND METHODS: Materials and Methods: Patients with SAR in the acute stage on the background of anxiety disorders were studied. Immunological studies were carried out, an assessment of the dynamics of indicators of the quality of life of patients, the level of anxiety / depression was assessed. In the clinical group, a variant of therapy modification was proposed. RESULTS: Results: Significant changes in the subpopulation ratio of lymphocytes, an increase in the immunoregulatory index, which indicated the severity of the immunological process, were revealed in SAR patients in the acute stage against the background of anxiety disorders. At the same time, a significant activation of the humoral link of immunity was observed: an increase and a significant increase in IgE in the blood serum and an increase in the content of sIgA in the nasal secretion. In most patients, eosinophilia was found in the peripheral blood and in the rhinocytogram before treatment. In the study of the quality of life of patients, changes in many parameters were found. CONCLUSION: Conclusions: The combination of "Nazafort Allergy Protection" and Atarax seems to be the most successful, which significantly improved the physical and psycho-emotional state of patients with SAR, complicated by anxiety and neurotic disorders. This combination led to an increase in the stress resistance of patients.

Sublingual immunotherapy for cedar pollinosis possibly triggers eosinophilic esophagitis.

Sublingual immunotherapy (SLIT) is an effective and popular treatment for cedar pollinosis. Although SLIT can cause allergic side effects, eosinophilic esophagitis (EoE) is a lesser-known side effect of SLIT. A 26-year-old male with cedar pollinosis, wheat-dependent exercise-induced anaphylaxis, and food allergies to bananas and avocados presented with persistent throat itching, difficulty swallowing, heartburn, and anterior chest pain 8 days after starting SLIT for cedar pollinosis. Laboratory examination showed remarkably elevated eosinophils, and esophagogastroduodenoscopy revealed linear furrows in the entire esophagus. Histological examination of an esophageal biopsy specimen revealed high eosinophil levels. The patient was strongly suspected with EoE triggered by SLIT. The patient was advised to switch from the swallow to the spit method for SLIT, and the symptoms associated with SLIT-triggered EoE were reduced after switching to the spit method. This case highlights the importance of recognizing SLIT-triggered EoE as a potential side effect of SLIT for cedar pollinosis, especially with the increasing use of SLIT in clinical practice. EoE can occur within a month after initiating SLIT in patients with multiple allergic conditions, as observed in our case. Furthermore, the spit method should be recommended for patients who experience SLIT-triggered EoE before discontinuing SLIT.

Association between Polyunsaturated Fatty Acid Intake and Eczema in Children and Adolescents.

INTRODUCTION: Eczema is a common allergic skin condition among children and adolescents, and polyunsaturated fatty acids (PUFAs) are a kind of fatty acid which were reported to be associated with reduced risk of eczema. Previous studies explored different types of PUFAs with various age groups of children and adolescents, and the influence of confounding factors such as medicine use was not considered. In the present study, we aimed to identify the associations between PUFAs and the risk of eczema in children and adolescents. These findings of our study might help better understand the associations between PUFAs and eczema. METHODS: This cross-sectional study collected the data of 2,560 children and adolescents aged 6-19 years from National Health and Nutrition Examination Surveys (NHANES) between 2005 and 2006. Total PUFA, omega-3 (n-3), including octadecatrienoic acid/18:3, octadecatrienoic acid/18:4, eicosapentaenoic acid/20:5, docosapentaenoic acid/22:5, and docosahexaenoic acid/22:6, omega-6 (n-6), including octadecatrienoic acid/18:2 and eicosatetraenoic acid/20:4, total n-3 intake, total n-6 intake, and n-3/n-6 were main variables in this study. Univariate logistic regression was applied for identifying potential confounders for eczema. Univariate and multivariate logistic regression analysis were conducted to explore the associations between PUFAs and eczema. Subgroup analysis was performed on subjects with different ages, and patients complicated with other allergic diseases, allergy, and medicine use or not. RESULTS: In total, there were 252 (9.8%) subjects who had eczema. After adjusting for confounding factors including age, race, poverty to income ratio (PIR), medicine use, hay fever, sinus infection, body mass index (BMI), serum total immunoglobulin E (IgE) antibody, and IgE, we observed that eicosatetraenoic acid/20:4 (OR = 0.17, 95% CI: 0.04-0.68) and total n-3 (OR = 0.88, 95% CI: 0.77-0.99) were linked with decreased risk of eczema in children and adolescents. Eicosatetraenoic acid/20:4 was correlated with decreased risk of eczema in participants without hay fever (OR = 0.82, 95% CI: 0.70-0.97) and medicine use (OR = 0.80, 95% CI: 0.68-0.94) or with allergy (OR = 0.75, 95% CI: 0.59-0.94). Total n-3 intake was associated with a reduced risk of eczema with the adjusted OR of 0.84, 95% CI: 0.72-0.98) in participants without hay fever. In those without sinus infection, octadecatrienoic acid/18:4 was linked with decreased risk of eczema (OR = 0.83, 95% CI: 0.69-0.99). CONCLUSION: N-3 and eicosatetraenoic acid/20:4 might be associated with the risk of eczema in children and adolescents.

The add-on effect of an intranasal antihistamine with an intranasal corticosteroid in Japanese cedar pollinosis.

OBJECTIVE: Combination intranasal drugs with a corticosteroid and antihistamine are available in several countries with better effect than treatments with single agents. However, it remains unclear whether this effect is also seen in Japanese cedar pollinosis (JCP), the most prevalent seasonal allergic rhinitis in Japan. We investigated the effect of an add-on intranasal antihistamine with an intranasal corticosteroid in JCP during the pollen dispersal period. (UMIN000025508) METHODS: We performed a double-blinded, randomized, placebo-controlled trial from March 1 to 14, 2017. Patients (n = 20 per group) received either a mometasone furoate nasal spray (MFNS) plus a levocabastine nasal spray (levocabastine group) or MFNS plus a placebo nasal spray (placebo group). The primary endpoint was the difference in the total nasal symptom score (TNSS) after treatment between the two groups. Differences in the total ocular symptom score, total symptom score, total medication score, total symptom-medication score, and five individual symptoms as well as safety were the secondary endpoints. RESULTS: The change in the TNSS from baseline was significantly greater in the levocabastine group than in the placebo group. A significant reduction in the TNSS was observed more than 6 days earlier in the levocabastine group than in the placebo group. Such add-on effects were also seen in the secondary endpoints. Both treatments were well-tolerated. CONCLUSION: The intranasal antihistamine provided better control of not only nasal symptoms, but also of ocular symptoms, and decreased the need for rescue medications when added to intranasal corticosteroid treatment in JCP patients.

Associations between endometriosis and allergy-related diseases as well as different specific immunoglobulin E allergy: A cross-sectional study.

AIM: To explore the associations between endometriosis and different kinds of allergy-related diseases as well as different specific immunoglobulin E (IgE) allergy. METHODS: This cross-sectional study included 1332 female participants ≥20 years and divided them into the endometriosis group (n = 97) and the nonendometriosis group (n = 1235). The confounders were obtained by comparing the differences of variables in groups. Univariate and multivariate logistic regression analyses were performed to analyze the associations between endometriosis and allergy-related diseases as well as different specific IgE allergy. Subgroup analysis were performed in age, body mass index (BMI), and pregnancy history. RESULTS: After adjusting for confounders, increased risk of allergy (odd ratios [OR] = 2.13, 95% confidence interval [CI]: 1.31-3.47), hay fever (OR = 2.31, 95%CI: 1.32-4.06), and dog-specific IgE (OR = 2.13, 95%CI: 1.03-4.41) were observed in females with endometriosis. Among females aged between 30 and 39 years, the risk of allergy (OR = 3.51, 95%CI: 1.07-11.56), hay fever (OR = 3.26, 95%CI: 1.08-9.83), and dog-specific IgE (OR = 4.39, 95%CI: 1.02-18.88) was increased in patients with endometriosis compared with those without. In terms of females aged 40 to 49 years, the risk of hay fever was increased in patients with endometriosis. For females with BMI of 25-30 kg/m2 , the risk of allergy was increased in patients with endometriosis. Increased risk of allergy, hay fever, and dog-specific IgE was observed in females with a history of pregnancy. CONCLUSION: Endometriosis was associated with higher risk of allergy, hay fever, and dog dander. Special care should be provided for patients with endometriosis for the potential risk of allergy.

Omalizumab is effective for a patient with pollen-food allergy syndrome who experienced intractable lip edema.

Pollen-food allergy syndrome (PFAS) is an immunoglobulin E (IgE)-mediated allergic reaction caused when patients with pollen allergy ingest food having cross-reactivity with pollen. To date, no effective treatment method for this has been established. Here we report the case of a patient with PFAS who experienced lip edema, causing difficulties in treatment. This report describes the case of a 12-year-old boy with perennial allergic rhinitis since the age of 8 years. After ingesting fresh fruits and raw vegetables at the age of 11 years, he started to experience lip edema repeatedly. Thus, the patient was referred to our department. Based on the results of serum antigen-specific IgE, prick-to-prick, and allergen component tests, he was diagnosed with PFAS. He has been instructed to avoid causative food. Furthermore, the treatment using an antihistamine and antileukotriene receptor antagonist was initiated for pollen allergy. Sublingual immunotherapy (SLIT) for Japanese cedar pollen was initiated because the patient experienced severe nasal allergy symptoms during the dispersal season of this pollen. These treatments alleviated the nasal symptoms; however, the lip edema persisted. Omalizumab administration improved the lip edema. The combination of SLIT and omalizumab may be an effective treatment option for patients with PFAS.

Ultra-processed foods and allergic symptoms among children and adults in the United States: A population-based analysis of NHANES 2005-2006.

Design: There is a strong correlation between dietary intake and allergic diseases. Ultra-processed foods (UPFs) are gradually becoming dominant worldwide and causing health problems for children and adults. We hope to determine whether links exist between UPFs and allergic symptoms. Methods: We investigated data from 2,736 children (16-19 years) and 4,256 adults (≥20 years) from the National Health and Nutritional Examination Survey (NHANES) 2005-2006. The associations between the mean UPFs contribution to total energy intake and all allergic symptoms (IgE, current asthma, allergy, rash, sneeze, wheeze, eczema, and hay fever) were estimated by weighted multivariate logistic regression. Results: Logistic regression analysis showed UFPs were negatively associated with IgE levels in children. Those with higher quartiles had a reduced risk from 16% (OR, 0.84, 95%CI, 0.55 to 1.28) to 34% (OR, 0.66, 95%CI, 0.49 to 0.89), p for trend = 0.006. UPFs were also positively related to current asthma in children with an increased risk of 11% (OR, 1.11, 95%CI, 0.79 to 1.56) to 76% (OR, 1.76, 95%CI, 1.10 to 2.82), p for trend = 0.0393. UPFs were also associated with eczema in girls. But there was no association observed between UPFs and allergic symptoms in adults. Conclusion: Our results suggested that UPFs assessed by the NOVA system were associated with IgE, current asthma in children, and eczema in girls. These results further support the need to test the association of modern dietary patterns with allergic symptoms.

Childhood blood eosinophils and symptoms of allergic disorders: a cross-sectional study in Southern China.

PURPOSE: The relationship between childhood blood eosinophils and subtypes of allergic diseases remains understudied. This study aimed to examine the associations between childhood blood eosinophils and subtypes of asthma, rhinitis and dermatitis, as well as the modifying effect of age. METHODS: We obtained concurrent blood cell counts and serum Immunoglobulin E (IgE) test results in 5026 children (0-13, years) from First Affiliated Hospital of Guangzhou Medical University from 2014 to 2019. Generalized additive models with multivariable adjustments were utilized to model the exposure-response relationship between eosinophils and allergic symptoms. The robustness of the association was assessed in two age categories (<6, 6-13 years). RESULTS: The association of eosinophils with allergic asthma/rhinitis was positively nonlinear, with a plateau at levels of Q4 (≥0.51, 109/L). Conversely, exposure-response curves between eosinophils and the risk of non-allergic asthma and rhinitis were negatively linear, and especially, became statistically significant when levels of eosinophils were larger than Q3 (≥0.30, 109/L). Compared with their counterparts, school-aged children (6-13, years) with a higher level of blood eosinophils (≥0.35, 109/L) were more likely to suffer from allergic asthma [relative excess risk due to interaction (RERI), 2.51; 95% CI, 1.24-3.78], allergic rhinitis (RERI, 2.79; 95% CI, 1.14-4.45) but not allergic dermatitis (RERI not significant). CONCLUSION: Higher eosinophil counts were associated with the increased risk of allergic subtype symptoms and the decreased risk of non-allergic subtypes in children. Moreover, the associations between eosinophils and allergic asthma/rhinitis were accentuated in the school-aged child. These findings may contribute to providing novel insights for clinical administration relevance of allergic-related symptoms.Key messages:There was a positively nonlinear association between childhood eosinophils and allergic asthma/rhinitis.Age modified the associations between eosinophils and allergy-related outcomes. The associations of eosinophil with allergic asthma/rhinitis accentuated in the school-aged child (6-13, years).

Assessing the prevalence and severity of asthma, rhinitis, and eczema among schoolchildren (6-7 and 13-14 years old) in Khuzestan, Iran: a cross-sectional survey.

BACKGROUND: Asthma and allergic complications are the most common chronic disorders in children and adolescents. This study aimed to determine the prevalence and severity of asthma, allergic rhinitis, eczema among schoolchildren, and some related risk factors. METHODS: The cross-sectional study was performed in 2019 and involved 4000 students aged 6-7 years and 4000 students aged 13-14 years (both girls and boys) from urban schools in Khuzestan Province, southwestern Iran. We used the multi-stage sampling method. Data were collected using the Persian version of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. RESULTS: The prevalence of current wheeze, wheeze ever and asthma ever in the age group of 6-7 years was 3.8, 4.5, and 1.8%, respectively; in the age group of 13-14 years, it was 4.4, 5.9, and 3.4, respectively. In terms of gender, males (4.9, 6.0, and 2.7 percent, respectively) had substantially higher rates of current wheeze, wheeze ever, and asthma ever compared to the girls (2.8, 3.6, and 2.0 percent, respectively) (p < 0.001). The prevalence of rhinitis, Hay fever, and eczema among young people was 5.3%, 3.5%, and 1.0%, respectively. Current wheeze was more common in children with allergic rhinitis in the last 12 months (30.3% vs. 2.7%, p < 0.001), Hay fever (32.8% vs. 0.3%, p < 0.001) and eczema (27.8% vs 3.8%, p < 0.001), compared to children who did not. CONCLUSIONS: The prevalence and severity of asthma symptoms were significantly associated with allergic rhinitis, eczema, and gender.

[Modern H1 antihistamines in the treatment of patients with allergic rhinitis and comorbid acute respiratory infections]. / Sovremennye H1-antigistaminnye sredstva v terapii patsientov s allergicheskim rinitom i komorbidnymi ostrymi respiratornymi infektsiyami.

Patients with allergic rhinitis (AR) have a predisposition to frequent acute respiratory viral infections (ARVI). Inflammation of the mucous membrane of the nasal cavity and paranasal sinuses in such patients is more pronounced against the background of a combination of allergic and infectious inflammation. OBJECTIVE: To evaluate the effect of therapy using modern antihistamines on the condition and severity of symptoms in adult patients with exacerbation of AR caused by plant pollen (seasonal) (SAR) and the development of ARVI. MATERIAL AND METHODS: An observational study was conducted at the Department of Otorhinolaryngology of the Evdokimov Moscow State University of Medicine and Dentistry of the Ministry of Health of the Russian Federation from April to August 2021. Included are patients of both sexes aged 18 to 65 years with a previously (at least 1 year ago) verified diagnosis of mild and moderate acute SAR in the acute stage, who sought medical help for ARVI. All patients were prescribed therapy with the inclusion of a drug belonging to the pharmacological group of antihistamines of the 2nd generation (a course of 14 days). In addition, patients received symptomatic ARVI therapy according to indications, including nasal decongestants (as needed), antipyretic and antitussive drugs. RESULTS: Based on the data obtained, it was possible to prove that the use of modern antihistamines in patients comorbid with AR and ARVI has a pronounced therapeutic effect. Theoritin provides a therapeutic effect at an early stage in relation to nasal and non-nasal symptoms of SAR/ARVI, and also quickly improves the quality of life of patients, which makes its use promising for the treatment of ARVI against the background of AR. The drug has an antihistamine activity comparable to cetirizine and surpasses it in its ability to suppress an allergic inflammatory reaction, for example on the skin, as well as in the duration of preservation of the antihistamine effect. CONCLUSION: The presented results indicate the effectiveness of theoritin and cetirizine in the treatment of patients with seasonal exacerbation of allergic rhinitis, comorbid for acute respiratory viral infections.

Oak Pollen Allergy in Korea.

Oak pollen allergy is common all over the world and an important cause of pollinosis. The molecular properties of some component allergens have been clearly characterized, while some of them are still waiting for characterization. Studies on some oak component allergens are neglected, possibly because of its high cross-reactivity to birch. However, the utilization of culprit allergen molecules is expected to increase the diagnostic sensitivity and efficacy of immunotherapy. Sensitization to oak pollen along with birch often causes pollen food allergy syndrome to fruits and vegetables. Acorn and wood dust from oak can cause allergic disease. We summarize the distribution and taxonomic classification of oak trees of allergenic importance. Molecular characteristics of the identified component allergens, cross-reactivity, and clinical aspects for diagnosis and immunotherapy are also described with an emphasis on Korean situations.

Importance of allergen-environment interactions in epidemic thunderstorm asthma.

Australia is home to one of the highest rates of allergic rhinitis worldwide. Commonly known as 'hay fever', this chronic condition affects up to 30% of the population and is characterised by sensitisation to pollen and fungal spores. Exposure to these aeroallergens has been strongly associated with causing allergic reactions and worsening asthma symptoms. Over the last few decades, incidences of respiratory admissions have risen due to the increased atmospheric concentration of airborne allergens. The fragmentation and dispersion of these allergens is aided by environmental factors like rainfall, temperature and interactions with atmospheric aerosols. Extreme weather parameters, which continue to become more frequent due to the impacts of climate change, have greatly fluctuated allergen concentrations and led to epidemic thunderstorm asthma (ETSA) events that have left hundreds, if not thousands, struggling to breathe. While a link exists between airborne allergens, weather and respiratory admissions, the underlying factors that influence these epidemics remain unknown. It is important we understand the potential threat these events pose on our susceptible populations and ensure our health infrastructure is prepared for the next epidemic.

Thunderstorm asthma in seasonal allergic rhinitis: The TAISAR study.

BACKGROUND: Asthma epidemics associated with thunderstorms have had catastrophic effects on individuals and emergency services. Seasonal allergic rhinitis (SAR) is present in the vast majority of people who develop thunderstorm asthma (TA), but there is little evidence regarding risk factors for TA among the SAR population. OBJECTIVE: We sought to identify risk factors for a history of TA and hospital presentation in a cohort of individuals with SAR. METHODS: This multicenter study recruited adults from Melbourne, Australia, with a past diagnosis of TA and/or self-reported SAR. Clinical information, spirometry results, white blood cell count, ryegrass pollen-specific (RGP-sp) IgE concentration, and fractional exhaled nitric oxide were measured to identify risk factors for a history of TA in individuals with SAR. RESULTS: From a total of 228 individuals with SAR, 35% (80 of 228) reported SAR only (the I-SAR group), 37% (84 of 228) reported TA symptoms but had not attended hospital for treatment (the O-TA group), and 28% (64 of 228) had presented to the hospital for TA (the H-TA group). All patients in the H-TA group reported a previous asthma diagnosis. Logistic regression analysis of factors associated with O-TA and H-TA indicated that lower FEV1 value and an Asthma Control Questionnaire score higher than 1.5 were associated with H-TA. Higher blood RGP-sp IgE concentration, eosinophil counts, and fractional exhaled nitric oxide level were significantly associated with both O-TA and H-TA. Receiver operating curve analysis showed an RGP-sp IgE concentration higher than 10.1 kU/L and a prebronchodilator FEV1 value of 90% or lower to be biomarkers of increased H-TA risk. CONCLUSION: Clinical tests can identify risk of a history of TA in individuals with SAR and thereby inform patient-specific treatment recommendations.

Esophageal Eosinophilia Is Common Among Relatives of Eosinophilic Esophagitis Patients.

BACKGROUND & AIMS: Familial clustering of eosinophilic esophagitis (EoE) has been described, and we report on the biopsy-assessed prevalence of esophageal eosinophilia (EE) in first-degree family members. The aim was to determine the prevalence of EE in first-degree adult relatives (FDRs) of EoE patients. METHODS: Index EoE patients diagnosed by EE (>15 eosinophils per high-power field) and proton pump inhibitor nonresponsiveness were identified and family trees were constructed. Adult FDRs were invited to undergo upper endoscopy with esophageal biopsies and to complete reflux, dysphagia, and allergy/atopy questionnaires. Questionnaire information was gathered only for those who responded as per institutional review board purview. Records from other children and adult FDRs with prior EoE diagnoses also were obtained when permission was obtained. Simple and multivariable logistic regression models were used to evaluate the unadjusted and odds ratios of EoE for demographic and clinical variables. RESULTS: A total of 239 FDRs from 37 index EoE patients were identified. Seventy-one of 239 adult (age, >18 y) FDRs completed endoscopy and questionnaires and 18 of 71 FDRs had EE. An additional 17 FDRs were confirmed to have EE after external medical record retrieval, resulting in a total of 35 of 239 (14.6%) FDRs with EE. Significantly more male FDRs had EE compared with female FDRs (P = .027). Proton pump inhibitors, dysphagia, gastroesophageal reflux disease, asthma, and reflux symptoms predicted EE in FDRs. FDRs who had EE reported hay fever, allergic eye symptoms, and food allergy more frequently than those without EE (P = .03, P = .001, and P = .02, respectively). Specifically, younger age, higher serum eosinophils, being male, and having food allergies all were associated with higher odds of EoE (P = .0211, P = .0031, P = .0362, and P = .0089, respectively). CONCLUSIONS: The prevalence of esophageal eosinophilia is extremely high and male-predominant in first-degree relatives of EoE patients. Symptoms of hay fever, allergic eye symptoms, and food allergy were predictors of EE in FDRs. Dysphagia did not predict esophageal eosinophilia. Family members of EoE patients are at risk for EE, particularly those who have atopic symptoms.

Prevalence of Gastro-esophageal Reflux Disease in Suspected Laryngo- pharingeal Reflux Unresponsive to Proton-pump Inhibitors.

BACKGROUND: Laryngopharyngeal Reflux (LPR) may be part of Gastroesophageal Reflux Disease (GERD). However, sometimes suspected LPR seems refractory to Proton Pump Inhibitors (PPI), questioning therefore the GERD diagnosis. Our aim was to evaluate the real-life prevalence of GERD in patients with a recent laryngoscopic diagnosis of LPR, and unresponsive to PPI. We also assessed whether other causes than GERD could explain the laryngoscopic findings in those patients. METHODS: We retrospectively analyzed patients with the diagnosis of LPR, and unresponsive to PPI. Those patients must have been investigated by: upper gastrointestinal endoscopy with biopsies; multichannel intraluminal impedance and pH monitoring (MII-pH); X-ray of the chest and/or of the paranasal sinuses; hormonal thyroid assessment; prick tests to assess food and/or inhalants and pollen allergy. RESULTS: We enrolled 28 patients (18, 64.3%, males and 10, 35.7%, females; median, IQR age 39.4, 21-75 yrs). Endoscopic hiatal hernia was found in 9/28 (32.1%) patients; the MII-pH analysis showed abnormality in 2/28 (7.14%) patients (both having also GERD symptoms); Chest X-ray found chest diseases in 2/28 (7.14%) patients and X-rays of the paranasal sinuses found sinusitis in 1/28 (3.6%); 2/28 (7.14%) patients had hyperthyroidism; food and/or inhalants and pollen allergy was found in 9 (32.1%) patients. In 12/28 (42.9%) patients, any of the investigated diseases was found. CONCLUSIONS: This study found that the real prevalence of GERD in patients with a recent laryngoscopic diagnosis of LPR, and unresponsive to PPI, is low. Moreover, more than 40% of them did not show any of the investigated diseases in real life.

Effect of rhinophototherapy on nasal congestion in patients with seasonal allergic rhinitis.

OBJECTIVE: The aim of the present study was to objectively and subjectively evaluate the effects of adding rhinophototherapy to intranasal beclomethasone dipropionate to treat nasal congestion in patients with seasonal allergic rhinitis. METHOD: Seventy-five seasonal allergic rhinitis patients were randomly divided into two groups. Patients in Group 1 received intranasal beclomethasone dipropionate for two weeks and patients in Group 2 had rhinophototherapy added to the same medical therapy as Group 1. The effectiveness of treatments was evaluated with the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), Nasal Obstruction Symptom Evaluation scale (NOSE) questionnaires and active anterior rhinomanometry. RESULTS: After treatment, significant improvement was observed in Group 2 vs Group 1 in terms of RQLQ (p = 0.011) and NOSE (p = 0.001) scores. In Group 2, significant differences were observed between before and after treatment for inspiratory total nasal resistance (p = 0.004). However, no significant differences vs. baseline were observed in Group 1. CONCLUSION: Our study shows that adding intranasal phototherapy with a combination of UVA, UVB and visible light therapy to nasal beclomethasone dipropionate treatment objectively improves nasal patency in patients with seasonal allergic rhinitis.

What is the contribution of IgE to nasal polyposis?

Taking a novel approach, this narrative review collates knowledge about nasal polyposis and the biological functions of IgE in several diseases (allergic rhinitis, allergic asthma, nonsteroidal anti-inflammatory drugs-exacerbated respiratory disease, and chronic spontaneous urticaria) to consider which IgE-mediated mechanisms are relevant to nasal polyposis pathology. A type 2 eosinophil-dominated inflammatory signature is typical in nasal polyp tissue of European patients with nasal polyposis, with a shift toward this endotype observed in Asian populations in recent years. Elevated polyclonal IgE is present in the nasal tissue of patients with and without allergy. It is derived from many different B-cell clones and, importantly, is functional (proinflammatory). Staphylococcus aureus enterotoxins are thought to act as superantigens, inducing production of polyclonal IgE via B-cell and T-cell activation, and triggering release of inflammatory mediators. In some patients, exposure to antigens/triggers leads to production of high levels of antigen-specific IgE, which mediates cross-linking of the high-affinity IgE receptor on various cells, causing release of inflammatory mediators. The efficacy of omalizumab confirms IgE as an important inflammatory mediator in nasal polyposis. By blocking IgE, omalizumab targets the T2 inflammation in nasal polyposis, reduces nasal polyp score and improves symptoms.
