Abstract

Nasal allergy is statistically related to inflammatory chronic sinusitis as a risk factor. But one question still remains unanswered: are the reactions and modifications observed in the sinuses after natural exposure to a nasal allergen or after nasal allergen challenge linked to an IgE mediated mechanism? Similarities in symptoms, eosinophils and mediators of inflammation in the mucosa have been found between allergic rhinitis and sinusitis. The same applies for the deposition of Major Basic Protein (MBP) and treatment results, especially when topical steroids are found. An original prospective study was held among 106 patients (24 patients allergic to perennial allergens, 82 non allergic patients) suffering from bilateral chronic inflammatory (no polyposis) ethmoidal sinusitis. The allergic group was submitted to a 3 months antiallergic treatment (Cetirizine 10 mg once a day, Beclomethasone dipropionate 50 micrograms three times a day) before being referred for bilateral endonasal ethmoidectomy under endoscopic control. Scores for rhinorrhea, nasal obstruction and global comfort (global assessment) were compared before and after ethmoidectomy. Both groups were significantly improved by surgery. Comparing both groups, no signi...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Adenomatous Polyposis Coli

Adenomatous polyposis coli is a protein encoded by the APC gene and acts as a tumor suppressor. Discover the latest research on adenomatous polyposis coli here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
