Background: Remodeling is considered a new or different reconstruction of tissues. The airway remodeling is a consequence of changes induced by endothelial cells and extra-cellular matrix as a result of chronic inflammation.
Objective: To show histological changes into mucosa in patients with perennial allergic rhinitis.
Material And Methods: We studied 26 patients with perennial allergic rhinitis, with evolution of 3 to 6 years, between 20 to 40 years old, without medical or immunological treatment. A turbinate biopsy was taken in all of them.
Results: We found enlargement of the basal membrane in 92.3%, subepithelial fibrosis in 92.4%, neutrophils in 100% of the cases, eosinophils in 100%, lymphocytes in 100%, edema in 46.2%, fragmented reticular fibers in 19.2%, and vascular dilatation in 11.1%.
Conclusion: These results suggest nasal remodeling in patients with allergic rhinitis, although more structural studies about this pathology are necessary.

This study aimed to investigate the relationship between allergen-specific immunoglobulin E (IgE) sensitization and allergic rhinitis (AR) symptoms in school-aged children in Japan and to understand the current severity of AR symptoms and the quality of life (QOL) among children with AR. We analyzed data from 8-year-old children who participated in the Yamanashi Adjunct Study of the Japan Environment and Children's Study, focusing on those with complete information on specific IgE levels and AR (1229 for perennial AR [PAR] and 1196 for seasonal AR [SAR]). Sensitization was determined when allergen-specific IgE levels were class 2 (0.

Pollen-food allergy syndrome is an IgE-mediated allergic reaction arising from cross-reactive homologous allergens found in both food and pollen. Allergens, such as pathogenesis-related protein class 10 and profilin, usually trigger oropharyngeal itching and numbness in patients, whereas lipid transfer proteins tend to induce anaphylaxis. This article presents a case study of an individual with Artemisia pollen allergy who experienced anaphylaxis after consuming red fruit ginseng, a perennial herb belonging to the Campanulaceae family.

The US practice parameter recommends the use of INAH or INCS as first-line therapy for the treatment of AR. Although not directly targeted to children, the recent US Practice Parameters proposed intranasal antihistamines as first-line therapy whereas the ARIA guidelines did not.

Purpose: The combination therapy of leukotriene receptor antagonists and antihistamines may alleviate allergic rhinitis (AR) symptoms better than monotherapy. This study aimed to investigate the safety and efficacy of Monterizine, a fixed-dose combination of montelukast and levocetirizine, compared to montelukast monotherapy in pediatric patients with AR.
Methods: One hundred seventy-six children aged 6 to 14 years with perennial AR symptoms were recruited.
