Abstract
Allergic diseases such as allergic rhinitis (AR), allergic asthma (AAS), atopic dermatitis (AD), food allergy (FA), and eczema are systemic diseases caused by an impaired immune system. Accompanied by high recurrence rates, the steadily rising incidence rates of these diseases are attracting increasing attention. The pathogenesis of allergic diseases is complex and involves many factors, including maternal-fetal environment, living environment, genetics, epigenetics, and the body's immune status. The pathogenesis of allergic diseases exhibits a marked heterogeneity, with phenotype and endotype defining visible features and associated molecular mechanisms, respectively. With the rapid development of immunology, molecular biology, and biotechnology, many new biological drugs have been designed for the treatment of allergic diseases, including anti-immunoglobulin E (IgE), anti-interleukin (IL)-5, and anti-thymic stromal lymphopoietin (TSLP)/IL-4, to control symptoms. For doctors and scientists, it is becoming more and more important to understand the influencing factors, pathogenesis, and treatment progress of allergic diseases. This review aimed to assess the epidemiology, pathogenesis, and therapeutic interventions of allergic diseases, including AR, AAS, AD, and FA. We hope to help doctors and scientists understand allergic diseases systematically.

[PMID: 36670145 PMCID: PMC9860019 DOI: 10.1038/s41598-023-28108-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 01/12/2023] [Indexed: 01/22/2023] Open
Abstract
The purpose of this study was to identify the inflammatory cytokines that were associated with pachychoroid neovasculopathy (PNV). Seventy-five eyes of 75 patients with PNV, 145 eyes of 145 patients with neovascular age-related macular degeneration without pachyvessels, and 150 eyes of 150 normal subjects were examined for the levels of intraocular cytokines. In eyes with PNV, the levels of IL-1α, IL-1β, IL-2, IL-4, IL-10, and VEGF were significantly higher than that of the controls. Logistic regression analysis showed that the highest association with the pachyvessels was found for IL-4, IL-2, and IL-1α. In eyes with PNV, the levels of IL-4, IL-2, IL-5, IL-13, IL-1α, and IL-1β were significantly higher in eyes with both increased choroidal thickness and choroidal vessel diameter. The strongest correlation with the choroidal thickness and vessel diameter was observed for IL-4. In PNV eyes with polypoidal lesions, the levels of IL-4, IL-17, and TNFβ were significantly correlated with the number of polypoidal lesions. Of these cytokines, IL-4 was especially associated with the thickness of the choroidal vessels and the formation of polypoidal lesions. We conclude that IL-4 is most likely involved in establishing the clinical characteristics of PNV and polypoidal vascular remodeling.

How an Immune-Factor-Based Formulation of Micro-Immunotherapy Could Interfere with the Physiological Processes Involved in the Atopic March. Int J Mol Sci 2023; 24:ijms24021483. [PMID: 36675006 PMCID: PMC9864899 DOI: 10.3390/ijms24021483] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 01/05/2023] [Accepted: 01/10/2023] [Indexed: 01/14/2023] Open
Abstract
Allergic diseases consist of improper inflammatory reactions to antigens and are currently an important healthcare concern, especially considering their increasing worldwide development in recent decades. The "atopic march" defines the paradigm of allergic diseases occurring in chronological order and displaying specific spatial manifestations, as they usually start as atopic dermatitis (AD) and food allergies during infancy and progressively evolve into allergic asthma (AA) and allergic rhinitis (AR) or rhino-conjunctivitis in childhood. Many immune cell subtypes and inflammatory factors are involved in these hypersensitivity reactions. In particular, the T helpers 2 (Th2) subset, through its cytokine signatures made of interleukins (ILs), such as IL-4, IL-5, IL-10, and IL-13, as well as mast cells and their related histamine pathways, contribute greatly to the perpetuation and evolution of the atopic march. By providing low doses (LD) and ultra-low doses (ULD) of ILs and immune factors to the body, micro-immunotherapy (MI) constitutes an interesting therapeutic strategy for the management of the atopic march and its symptoms. One of the aims of this review is to shed light on the current concept of the atopic march and the underlying immune reactions occurring during the IgE-mediated responses. Moreover, the different classes of traditional and innovative treatments employed in allergic diseases will also be discussed, with a special emphasis on the potential benefits of the MI medicine 2LALERG® formulation in this context.

A novel and alternative therapy for persistent allergic rhinitis via intranasal acupuncture: a randomized controlled trial. Eur Arch Otorhinolaryngol 2023; 280:2773-2783. [PMID: 36617611 PMCID: PMC10175315 DOI: 10.1007/s00405-022-07793-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 12/12/2022] [Indexed: 01/10/2023]
Abstract
BACKGROUND Acupuncture is used to treat allergic rhinitis (AR) in traditional Chinese medicine, and the ST2 and ST36 acupoints are generally selected in clinical practice. We report a new intranasal acupuncture method at the Neiyingxiang (EX-HN9) and Biqiu points for the treatment of persistent AR (PAR). Here, the efficacy and safety of this method were evaluated. METHODS A total of 120 patients diagnosed with PAR were randomly allocated (2:1 ratio) to intranasal acupuncture or Western medicine groups, the basic principle of random grouping is SAS random grouping method. The applicator held a nasal endoscope and a 0.30 × 75 mm filiform needle in their left and right hands, respectively. When aiming at the Neiyingxiang or Biqiu point, the applicator quickly inserted the needle to a 20-mm depth as parallel as possible to the inferior turbinate or middle turbinate, without special reinforcing and reducing techniques (the needle remained for 20 min). The intranasal acupuncture groups received acupuncture treatment three times per week for 2 weeks. The Western medicine group was treated with budesonide nasal spray (two sprays/nostril, twice/day) and loratadine (one tablet/night) for 2 weeks. Visual analog scale (VAS) scores were the primary outcome. Quality of life, medication dosages and adverse events were secondary outcomes measured using the Rhinoconjunctivitis Quality-of-Life Questionnaire (RQLQ). Confidence assessments were performed to evaluate data from the treatment and follow-up periods. RESULTS The results were as follows: (1) VAS and RQLQ scores were significantly lower in the intranasal acupuncture group than in the Western medicine group on day 1 (i.e., first treatment) (P < 0.05; 95% CI - 13.1 to - 9.6 VAS points) (P < 0.05; 95% CI - 20.27 to - 12.28 RQLQ points). Overall symptoms (95% CI - 2.86 to - 1.86 points), nasal obstruction (95% CI - 6.33 to - 5.36 points), olfactory function (95% CI - 2.91 to - 1.75 points), sleep (95% CI - 5.05 to - 3.57 points), actual problems (95% CI - 2.03 to - 0.06 points), nasal symptoms (95% CI - 6.62 to - 4.5 points), and emotional problems (95% CI - 5.05 to - 3.5 points) were significantly improved. (2) VAS and RQLQ scores in the two groups were significantly improved at week 2; however, there were no significant group differences in the VAS (P > 0.05; 95% CI - 1.21 to - 1.38 points) and RQLQ (P > 0.05; 95% CI - 0.33 to - 3.46 points) scores. Olfactory function symptoms were significantly improved (95% CI - 1.58 to - 0.21 points). (3) During the follow-up period, there was a significant difference between the two groups (P < 0.05) with higher RQLQ and VAS scores in the intranasal acupuncture group than in the Western medicine group. VAS scores on rhinobyon symptoms, nasal itch, rhinorrhea and olfactory function and RQLQ scores for activities, non-nasal/eye symptoms, actual problems, nasal symptoms, and eye symptoms were significantly improved. (4) No adverse events were observed in either group during treatment. CONCLUSIONS Intranasal acupuncture has good efficacy and safety in the treatment of PAR. Moreover, VAS and RQLQ scores were much lower in the intranasal acupuncture group than in the Western medicine group, and acupuncture had an immediate impact, especially for improving nasal congestion, olfactory function and sleep.

J Asthma Allergy 2022; 15:1321-1335. [PMID: 36132977 PMCID: PMC9482964 DOI: 10.2147/jaa.s372314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Accepted: 08/29/2022] [Indexed: 11/23/2022] Open
Abstract
Background Allergic rhinitis (AR) is a common allergic disease in otolaryngology. Its pathogenesis is still unclear. PLC1 plays a key role in calcium homeostasis and immune response, which is potentially related to AR. We aimed to explore the association between PLCL1 genetic loci and susceptibility to AR. Methods We recruited 1975 volunteers to perform an association analysis through SNPStats online software. False-positive report probability (FPRP) analysis was used to detect whether the positive findings were worth noting. Linkage disequilibrium and haplotype analysis were completed through Haploview and SNPStats. The influence of SNP-SNP interaction on AR susceptibility was evaluated through multifactor dimensionality reduction (MDR). Results The results showed that four genetic loci in PLCL1 (rs2139049, rs212164068, rs2228135, and rs6738825) are associated with AR susceptibility under multiple genetic models. Allele "A" of PLCL1-rs2139049 (OR = 0.85, p = 0.031) or of -rs212164068 (OR = 0.85, p = 0.030), and allele "G" of PLCL1-rs6738825 (OR = 0.84, p = 0.022) are significantly associated with reduced AR risk. PLCL1-rs2228135 is associated with an increased risk of AR in males or participants older than 43 years of age. FPRP analysis showed that most of positive results are noteworthy findings. Three loci model composed of rs2139049, rs2164068, and rs2228135 is the best model for predicting AR risk (p = 0.0022). In addition, the haplotype "Grs2139049Ars6738825Ars2164068Ars2228135" (OR = 0.50, p = 0.033) can reduce the AR risk. Conclusion Allele "A" of PLCL1-rs2139049, allele "A" of -rs212164068, and allele "G" of PLCL1-rs6738825 are protective factors of AR in Han population from northern Shaanxi, China.

Abstract
Background: Allergic rhinitis (AR) is an especially common disorder associated with both environmental and genetic factors, and a lot of researchers have attempted to find polymorphisms which predisposed to the disease. We conducted a meta-analysis of the most frequently researched polymorphisms to find those genes which may be susceptible to AR and then may be of value in diagnosis. Methods: Pubmed and China National Knowledge Infrastructure (CNKI) databases were searched to screen out eligible studies focusing on the correlation between polymorphisms and AR susceptibility, and then polymorphisms cited in at least 3 studies were selected. Results: The 142 papers originally selected cited 78 genes. Twelve genes (coinciding with 23 polymorphisms) were reported in more than three papers. Twenty-three polymorphisms were involved in the meta-analysis. Among the 23 polymorphisms, only 4 were found to be related to the risk of AR: IL-13 rs20541, CTLA-4 rs11571302, IL-4R RS1801275 and ACE (I/D). The remaining 19 of the 23 polymorphisms were not associated with AR. Conclusion: We found polymorphisms that could be used for AR diagnosing and those that were unrelated to AR. This may be the first step in detecting polymorphic combinations susceptible to AR (IL-13 RS20541, CTLA-4 RS11571302, IL-4R RS1801275 and ACE (I/D). In addition, our results may improve AR diagnosis and contribute to the intensive study of AR.

Abstract
Environmental factors play an important role in the development and exacerbation of allergic rhinitis (AR) in childhood. Indoor air pollution, such as house dust mites and secondhand smoke, can significantly increase the onset of AR, while pet dander may affect the exacerbation of AR symptoms in children. Furthermore, traffic related air pollution and pollen are outdoor air pollutants that can affect immune competency and airway responsiveness, increasing the risk of AR in children. Climate change has increased AR in children, as growth patterns of allergenic species have changed, resulting in longer pollen seasons. More extreme and frequent weather events also contribute to the deterioration of indoor air quality due to climate change. Additionally, viruses provoke respiratory tract infections, worsening the symptoms of AR, while viral infections alter the immune system. Although viruses and pollution influence development and exacerbation of AR, a variety of treatment and prevention options are available for AR patients. The protective influence of vegetation (greenness) is heavily associated with air pollution mitigation, relieving AR exacerbations, while the use of air filters can reduce allergic triggers. Oral antihistamines and intranasal corticosteroids are common pharmacotherapy for AR symptoms. In this review, we discuss the environmental risk factors for AR and summarize treatment strategies for preventing and managing AR in children.
