Molecular Aspects of Allergen-Specific Immunotherapy in Patients with Seasonal Allergic Rhinitis

A systematic review and narrative synthesis of publications was undertaken to analyze the role of component-resolved diagnosis technology in identifying polysensitization for the provision of allergen-specific immunotherapy to patients with seasonal allergic rhinitis. A search of publications was carried out in electronic databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search helped to identify 568 publications, 12 of which were included in this review. Overall, 3302 patients were enrolled. The major finding was that component-resolved diagnostics change the choice of relevant allergens for allergen-specific immunotherapy in at least 50% of cases. Sensitization to allergen components differs with age, type of disease, and overall disease duration. Patients who had both bronchial asthma and allergic rhinitis were sensitized to a larger number of allergens than patients who had bronchial asthma alone.

Allergic Rhinitis: Pathophysiology and Treatment Focusing on Mast Cells

Allergic rhinitis (AR) is a common rhinopathy that affects up to 30% of the adult population. It is defined as an inflammation of the nasal mucosa, develops in allergic individuals, and is detected mostly by a positive skin-prick test. AR is characterized by a triad of nasal congestion, rhinorrhea, and sneezing. Mast cells (MCs) are innate immune system effector cells that play a pivotal role in innate immunity and modulating adaptive immunity, rendering them as key cells of allergic inflammation and thus of allergic diseases. MCs are typically located in body surfaces exposed to the external environment such as the nasal mucosa. Due to their location in the nasal mucosa, they are in the first line of defense against inhaled substances such as allergens. IgE-dependent activation of MCs in the nasal mucosa following exposure to allergens in a sensitized individual is a cardinal mechanism in the pathophysiology of AR. This review is a comprehensive summary of MCs' involvement in the development of AR symptoms and how classical AR medications, as well as emerging AR therapies, modulate MCs and MC-derived mediators involved in the development of AR.

Turkish Guideline for Diagnosis and Treatment of Allergic Rhinitis (ART)

OBJECT

To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients.

METHODS

The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article.

RESULTS

A detailed guideline about all aspects of allergic rhinitis was created.

CONCLUSION

The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

Interactive Network Platform Improves Compliance and Efficacy of Subcutaneous Immunotherapy for Patients with Allergic Rhinitis

BACKGROUND

Allergic rhinitis (AR) is a common chronic inflammatory disease of nasal mucosa worldwide, and its symptoms seriously affect the lives of patients. Subcutaneous immunotherapy (SCIT) is an effective treatment for AR, but it is also associated with low patient compliance and difficulties in fully achieving therapeutic effects.

OBJECTIVE

In this prospective randomized controlled study, we verified the effects of an interactive network platform named "U breath" in improving patient compliance and the efficacy of SCIT in patients with AR.

METHODS

A total of 148 patients who received SCIT were recruited as participants and randomly assigned to either the standardized management (SM) or the interactive network platform management (INP) group. The SM group experienced the standard management SCIT process. The INP group experienced a new management approach based on an interactive network platform called "U breath". The compliance rate, combined symptom and medication score (CSMS), visual analogue scale score and the rhinoconjunctivitis quality of life questionnaire (RQLQ) results were evaluated at baseline and 1-year postintervention for the two groups.

RESULTS

Within the first year of treatment, the INP group had a higher compliance rate than did the SM group, with a statistically significant difference (P<0.05). The INP group showed better clinical improvement than the SM group did in terms of the VAS score, and the RQLQ score except the sleep problems (P< 0.05).

CONCLUSION

This study confirmed that the application of an interactive network platform is of great significance for improving patient compliance and the treatment effects of SCIT in patients with AR.

This chapter explores the common cold and influenza and associated symptoms, including cough, congestion, rhinorrhea, sore throat, diarrhea, pain, and fever. This chapter will aid pharmacists in identifying the characteristics and pharmacological and nonpharmacological management of these conditions. Allergies of the nose and eyes are another common ailment encountered in the community pharmacy, and this chapter assists pharmacists in reaching a differential diagnosis and strategies to manage these conditions.

Practice Patterns for Chronic Respiratory Diseases in the Asia-Pacific Region: A Cross-Sectional Observational Study

BACKGROUND

Allergic rhinitis (AR), asthma, chronic obstructive pulmonary disease (COPD), and rhinosinusitis are common and little studied in the Asia-Pacific region.

OBJECTIVES

We sought to investigate real-world practice patterns for these respiratory diseases in India, Korea, Malaysia, Singapore, Taiwan, and Thailand.

METHODS

This cross-sectional observational study enrolled adults (age ≥18 years) presenting to general practitioners (GP) or specialists for physician-diagnosed AR, asthma, COPD, or rhinosinusitis. Physicians and patients completed study-specific surveys at one visit, recording patient characteristics, health-related quality of life (QoL), work impairment, and healthcare resource use. Findings by country and physician category (GP or specialist) were summarized.

RESULTS

Of the 13,902 patients screened, 7,243 (52%) presented with AR (18%), asthma (18%), COPD (7%), or rhinosinusitis (9%); 5,250 of the 7,243 (72%) patients were eligible for this study. Most eligible patients (70-100%) in India, Korea, Malaysia, and Singapore attended GP, while most (83-85%) in Taiwan and Thailand attended specialists. From 42% (rhinosinusitis) to 67% (AR) of new diagnoses were made by GP. On average, patients with COPD reported the worst health-related QoL, particularly to GP. Median losses of work productivity for each condition and activity impairment, except for asthma, were numerically greater for patients presenting to GP vs. specialists. GP prescribed more antibiotics for AR and asthma, and fewer intranasal corticosteroids for AR, than specialists (p < 0.001 for all comparisons).

CONCLUSIONS

Our findings, albeit mostly descriptive and influenced by between-country differences, suggest that practice patterns differ between physician types, and the disease burden may be substantial for patients presenting in general practice.

The Association of Industry Payments to Physicians with Prescription of Brand-Name Intranasal Corticosteroids

Objectives To examine the association of industry payments for brand-name intranasal corticosteroids with prescribing patterns. Study Design Cross-sectional retrospective analysis. Setting Nationwide. Subjects and Methods We identified physicians prescribing intranasal corticosteroids to Medicare beneficiaries 2014-2015 and physicians receiving payment for the brand-name intranasal corticosteroids Dymista and Nasonex. Prescription and payment data were linked by physician, and we compared the proportion of prescriptions written for brand-name intranasal corticosteroids in industry-compensated vs non-industry-compensated physicians. We associated the number and dollar amount of industry payments with the relative frequency of brand-name prescriptions. Results In total, 164,587 physicians prescribing intranasal corticosteroids were identified, including 7937 (5%) otolaryngologists; 10,800 and 3886 physicians received industry compensation for Dymista and Nasonex, respectively. Physicians receiving industry payment for Dymista prescribed more Dymista as a proportion of total intranasal corticosteroid prescriptions than noncompensated physicians (3.1% [SD = 9.6%] vs 0.2% [SD = 2.5%], respectively, P < .001). Similar trends were seen for Nasonex (12.0% [SD = 16.8%] vs 4.8% [SD = 13.6%], P < .001). The number and dollar amount of payment were significantly correlated to the relative frequency of Dymista (ρ = 0.26, P < .001 and ρ = 0.20, P < .001, respectively) and Nasonex prescriptions (ρ = 0.09, P < .001 and ρ = 0.15, P < .001, respectively). For Dymista, this association was stronger in otolaryngologists than general practitioners ( P < .001). There was a stronger correlation between the percentage of prescriptions and the number and dollar amount of payments for Dymista than for Nasonex ( P = .014 and P < .001). Conclusions Industry compensation for brand-name intranasal corticosteroids is significantly associated with prescribing patterns. The magnitude of association may depend on physician specialty and the drug's time on the market.
