[PMID: 36400113 DOI: 10.1016/j.mcp.2022.101872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 10/26/2022] [Accepted: 11/04/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Recently developed Immunoglobulin-E (IgE) based molecular allergy diagnostics provide the ability of identifying allergenic components or ingredients at the molecular level (component-resolved-diagnosis, CRD). Compared to the classical IgE-based allergy diagnostics, molecular technology is providing more sensitive and specific IgE-sensitization patterns. Certain sensitization patterns are characteristic of large geographic regions. There are only few data available on the molecular IgE sensitization patterns in East-Central Europe. This study aims to present further data from this region. METHODS Data of 3993 stored, anonymized molecular ImmunoCap IgE measurements (CRD), performed in Hungary between January-December 2019 from sera of 1288 subjects (mean age: 27 years ±18 years, male/female ratio 0.56) were analyzed retrospectively, in order to get a local distributional pattern of the sensitizing (IgE >0.35 KU/l) molecular allergens. RESULTS The proportion of CRD positive cases was 24.3%. Amongst them, the most prevalent inhalative allergens were Amb a 1 (18%) Art v 1 (8%) in adults and Der p 2 (3%) and Der p 1 (3%) and Amb a 1 (4%) in subjects below 18 years of age. The same for food allergens were Gal d 2 (21%), Bos d 4 (17%), Bos d 5 (11%) in adults and Gal d 2 (38%), Gal d 1 (28%), Bos d 4 (21%), Bos d 5 (13%) and Bos d 8 (7%) in children. The ratio of mono-sensitivities among CRD-positive cases was 37.5%. CONCLUSION Our results provide region-specific patterns of sensitization and molecular allergen spreading for Hungary. The relatively higher abundance of polysensitization's among allergic cases underlines the need for early diagnostic -and preventive measures in the future.

Abstract
Allergic rhinitis (AR) is an inflammatory disorder of the nasal mucosa, and is a worldwide health problem with a significant impact on the quality of life. The main goal of AR treatment is to relieve symptoms. However, standard treatments have considerable side effects or are not effective. Photobiomodulation (PBM) therapy has emerged as an alternative treatment. Here, we evaluated the effects of transcutaneous systemic (tail) or local (skin over nostrils) PBM using a 660-nm light-emitting diode (LED) array. Adult rats were assigned into 4 groups: basal, as non-manipulated animals; Sham, as rats sensitized with 7 intradermal injections of ovalbumin (OVA) plus alum followed by intranasal instillation with OVA (2%) daily for 7 days; and the LPBM and SPBM groups, in which the animals were treated with PBM (local or systemic) immediately after the last instillation of OVA (1%) daily for 3 days. Our results showed that local PBM treatment reduced mast cell degranulation in the nasopharynx and nostrils; levels of leukotriene B4, thromboxane A2, and interleukin 4 (IL-4) in the nasopharynx; and gene expression of IL-4. Moreover, we showed higher levels and gene expression of IL-10 after local PBM treatment. Systemic PBM treatment did not change any of the evaluated parameters. In conclusion, our data showed that local (but not systemic) treatment with PBM could improve parameters related to AR in an animal model, and should be tested clinically.

Association of allergic rhinitis with hypothyroidism, asthma, and chronic sinusitis: Clinical and radiological features. World J Otorhinolaryngol Head Neck Surg 2021; 8:262-268. [PMID: 36159906 PMCID: PMC9479480 DOI: 10.1016/j.wjorl.2020.12.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 12/07/2020] [Indexed: 11/23/2022] Open
Abstract
Background Allergic rhinitis (AR) is characterized by mucosal inflammation that leads to a variety of symptoms, such as nasal congestion, rhinorrhea, and sneezing. This rhinitis is triggered by inhalation of allergens, such as pollen, and this condition has a negative impact on the quality of life. AR was shown to be associated with a number of co‐morbidities, including hypothyroidism, asthma, and chronic sinusitis. Objective This study aimed to assess AR‐associated comorbidities in patients presenting symptoms and paranasal sinus computed tomography (CT) scan findings in Taif City, Saudi Arabia. Methods This cross‐sectional study evaluated medical and radiological records of AR patients retrospectively from the period of December 2018 to September 2019 in Al‐Hada Armed Forces Military Hospital, Taif City, Saudi Arabia. Results A total of 103 AR patients with a mean age of 39.0 ± 15.6 years with 55.3% males and 44.7% females. The three most common associated comorbidities in allergic rhinitis patients were chronic sinusitis (28.2%), hypothyroidism (21.4%), and asthma (8.7%). Nasal obstruction (30.1%) was the symptom most frequently presented by all patients. Mucosal thickening occurred most frequently in patients with associated chronic sinusitis, while bilateral osteomeatal complex obliteration was observed mostly in asthmatic patients, and bony boundary thinning was more prevalent among patients with associated hypothyroidism. Conclusion The gender distribution of AR was 10% more common among males; however, the most common three comorbidites in allergic rhinitis patients were chronic sinusitis, hypothyroidism, and asthma, and most of those patients were females. Hypothyroidism can be a hidden predisposing factor for AR, while chronic sinusitis can be caused by AR due to secretion stasis or immune system activation.

Abstract
Group 2 innate lymphoid cells (ILC2s) and Th2 type immune response are critically involved in the pathogenesis of allergic rhinitis (AR), and this pathological process is influenced by microRNAs-mediated post-transcriptional regulation. The present study investigated the adaptation and function of miR-155 in AR patients and mouse model. We found that significantly increased miR-155 expression (1.63 ± 0.12 vs. 0.92 ± 0.11 in human, and 1.68 ± 0.15 vs. 1.06 ± 0.06 in mice) and ILC2s activity in nasal mucosa and serum in AR patients and mice. Administration of miR-155 antagomir significantly reduced the activity of ILC2s in nasal mucosa, suppressed the production of Th2 cytokines in serum and nasal mucosa, and alleviated the airway inflammation and allergic symptoms in AR mice, while miR-155 agomir increased ILC2s activity and production of Th2 cytokines and induced airway inflammation and allergic symptoms in control mice. Meanwhile, the expression of transcriptional factor c-Maf (0.57 ± 0.05 vs. 0.37 ± 0.04) in nasal mucosa in AR mice, which was significantly recovered by miR-155 antagomir (0.56 ± 0.04). Treatment with miR-155 agomir decreased c-Maf expression in nasal mucosa in control mice. This synchronized with the similar pattern in the current observations that miR-155 regulated Th2 cytokine (IL-4, IL-5, IL-9 and IL-13) production, airway inflammation and allergic symptoms in AR mice. Together, upregulation miR-155 suppressed the expression of transcriptional factor c-Maf and was critically involved in the ILC2s activation, which contributed to the airway inflammation and allergic symptoms in AR.

Abstract
This article reviews the current understanding of the role of air pollution in both the symptom exacerbation and rising prevalence of allergic rhinitis (AR) for the development of future AR therapeutics and management strategies. We discuss the epidemiological evidence for this relationship through birth cohort studies, the economic impact of AR, and the influence of air pollution through the lens of the exposome framework of allergic disease development. This is followed by a discussion on the influence of diesel exhaust and diesel exhaust particles (DEP) from motor vehicle emissions and their implication in the rising prevalence of allergic disease and allergic sensitization through triggering inflammatory signalling pathways that exacerbate AR symptoms. Finally, a summary is provided of clinical trials assessing the influence of air pollution on AR with a depiction of currently available therapies and management strategies. Future directions in the development of AR modalities given the air pollution-mediated symptom exacerbation are challenged with unfolding the complex gene–environment interaction product of heterogenous AR presentation.

Abstract
Background Sensitization to common mold allergens is one of the major causes of allergic rhinitis and asthma. Therefore, there is a critical need for standard sensitivity tests including skin prick tests to improve the stability of fungi extracts in traditional allergenic formulations. To address this concern, the present study aimed to develop a formulation to preserve allergenic activity of mold extracts. Methods 48 stabilizer formulations were designed and monitored for allergenic activity during a 40-days incubation period at 37 °C using an ELISA. Specifically, the IgE reactivity of allergenic A. alternata extracts were examined. After establishing the most effective stabilizer formulation, we evaluated whether it could protect the allergenic activity of Alt a1, A. fumigatus, and C. herbarum using an IgE inhibition ELISA after 40 days at 37 °C. Results We demonstrated that the most effective stabilizer formulation was a glycerol-based extract containing Arg and Glu. This formulation had an equal ratio of sucrose, sorbitol and protein and was able to preserve more than 95% of allergenic A. alternata extract activity during a 40-days incubation period at 37 °C. Conclusion The present study reveals a novel formulation that is an efficient stabilizer of allergenic mold extract activity and has practical applications in mold skin prick tests, ELISAs, immunotherapies, and RAST.

Abstract
Allergen-specific immunotherapy (AIT) is currently the only potential treatment for allergies including allergic rhinitis (AR) and food allergies (FA) that can modify the underlying course of the diseases. Although AIT has been performed for over a century, the precise and detailed mechanism for AIT is still unclear. Previous clinical trials have reported that successful AIT induces the reinstatement of tolerance against the specific allergen. In this review, we aim to provide an updated summary of the knowledge on the underlying mechanisms of IgE-mediated AR and FA as well as the immunological changes observed after AIT and discuss on how better understanding of these can lead to possible identification of biomarkers and novel strategies for AIT.

Abstract
BACKGROUND Although 5-grass pollen sublingual immunotherapy has a good safety profile in controlled clinical trials, additional safety information among pediatric patients in a real-world setting would be useful. OBJECTIVE To further document the safety of 5-grass tablet among children aged 5 to 9 years with allergic rhinoconjunctivitis (ARC). METHODS This multicenter, observational study included allergy immunotherapy-naïve 5- to 9-year-old children with grass pollen-induced ARC prescribed with 5-grass tablet daily (3-day dose escalation to 300 index of reactivity [IR]). Patients were followed up daily for safety and tolerability over the first 30 treatment days. Adverse events (AEs) and adverse drug reactions (ADRs) were analyzed descriptively. RESULTS Three hundred seven children (mean age, 7.1 years) were enrolled. Fifty-eight percent were confirmed as polysensitized, and 36% had mild-to-moderate asthma. Of 307 patients, 233 (76%) reported AEs, and 173/307 (56%) reported ADRs, most frequently mild application-site reactions (throat irritation, oral pruritus, oral paresthesia). Sixteen of 307 (5.2%) patients withdrew because of ADRs. In 143 of 173 (83%) patients, ADRs first occurred within 1 week of starting treatment. More than half of the ADRs lasted less than 2 days, and ADRs resolved spontaneously in 161 of 173 (93%) patients. Recurrences of ADRs were reported in 45 of 173 (26%) patients and were also mainly application-site reactions. No notable differences were found in ADRs related to whether patients had asthma at inclusion. Neither epinephrine use nor admission to intensive care unit was reported. CONCLUSION The safety profile of 5-grass tablet in pediatric ARC patients aged 5 to 9 years was consistent with safety findings in older patients, most ADRs being at the application site and mild to moderate. ClinicalTrials.gov identifier: NCT02295969; EUPAS registration number: 8104.
