Azelastine was suggested as a supplementary choice of glucocorticoid for the control of moderate to severe allergic rhinitis (AR). However, the underlying mechanism has not been completely understood. In this study, primary cultured nasal epithelial cells and bronchial epithelial cells were
BACKGROUND
The role of antigen presenting cells (APC) in allergic rhinitis is underexposed. Allergen presentation to T lymphocytes is probably an important aspect of the pathophysiological mechanism of allergic rhinitis.
OBJECTIVE
The aim of the study was to investigate the presence and dynamics of
OBJECTIVE
Th-2 type cytokine production (Interleukin-4 [IL-4] and interleukin-5 [IL5]) has been demonstrated to play a significant role in the pathophysiology of allergic rhinitis (AR), and the treatment of AR with topical corticosteroids has been shown to reduce the expression of Th-2 type
OBJECTIVE
Th-2 type cytokine production (interleukin-4 [IL-4] and interleukin-5 [IL-5]) has been demonstrated to play a significant role in the pathophysiology of allergic rhinitis (AR), and the treatment of AR with topical corticosteroids has been shown to reduce the expression of Th-2 type
OBJECTIVE
To study the effects of long term use of beclomethasone dipropionate (BDP) nasal spray on bone density with perennial allergic rhinitis (AR) in adults.
METHODS
A 5-year randomized study was conducted on the effects of BDP nasal spray on serum calcium, phosphorus, alkaline phosphatase, and
Allergic rhinitis (AR) is an IgE-mediated upper airway disease, and its impact on asthma has been widely recognized. Protein tyrosine phosphatase non-receptor 22 (PTPN22) gene and the cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) gene polymorphisms have been reported to be associated with
This study evaluated the effects on bone mineral status of long-term treatment with intranasal budesonide (INB) spray, using the recommended dose, in pediatric patients with allergic rhinitis (AR). This retrospective, case-control study of 230 prepubertal children with perennial AR, who had used
Having in view the concept about a close relationship between morphofunctional changes and clinical picture of the disease, 35 patients of different sex, age and various duration of the disease were examined, in order to clarify certain modifications of chronic rhinitis and mechanisms of its
The effects of a three-month course of oral ketotifen on the histology and histochemistry of nasal mucosa, assessed on punch biopsy material, were studied in 30 adults with perennial allergic rhinitis. Ketotifen treatment was associated with reversal of the histopathology and enzyme changes in every
BACKGROUND
Nasal allergen provocation has demonstrated that allergen-induced rhinitis is associated with an increase in local IL-4 mRNA and IgE heavy chain (Cepsilon) and IgE heavy chain promoter (Iepsilon) RNA and that pretreatment with topical glucocorticosteroids inhibits the increase in these
Macrophages are the most common cell type residing in the lumen of the lower airways. However, very little is known about the presence and putative pathogenic implications of macrophages in the upper airways. Using specific immunohistochemical techniques, the presence of and changes in macrophage
We recently shown a novel neuro-immune competition between vasoactive intestinal peptide (VIP) and PGD2 for CRTH2 receptor, and that genistein augmented VIP and PGD2-induced eosinophil chemotaxis. However, there are neither studies on the CRTH2 gene expression in allergic rhinitis (AR) nor in the
In 239 German patients with atopic conditions (atopic dermatitis, hay fever, allergic rhinitis, bronchial asthma, and acute urticaria) the phenotype and gene distribution of 15 genetic blood polymorphisms (ABO, MNSs, rhesus, P, Kell, Duffy, Kidd, Hp, Gc, Gm, Inv, aP, PGM1, EsD, and 6-PGD) were
The enzymatic changes in chronic hypertrophic rhinitis were studied in 14 patients. The cholinesterase content was increased in the subepithelium and stroma, denoting parasympathetic hyperactivity. Acid phosphatase was increased in the epithelium, subepithelium and around the glands, indicating
BACKGROUND
Allergic rhinitis (AR) is an inflammatory disorder of the upper airway. Protein tyrosine phosphatase non-receptor 22 encoded by PTPN22 gene and cytotoxic T-lymphocyte associated 4 encoded by Ctla4 gene are associated with autoimmune diseases.
OBJECTIVE
This study was performed to evaluate
