THE EPIDEMIOLOGY OF ALLERGIC RHINITIS IN JORDANIAN PATIENTS WITH CHRONIC RHINOSINUSITIS AT KING HUSSEIN MEDICAL CENTER.

Background:- Allergy is a leading factor to chronic rhinosinusitis with multiple causes. Chronic rhinosinusitis is correlated with various disorders as atopic disease, cystic fibrosis, immunologic disorders and ciliary dyskinesia. Objective: To assess the epidemiology of allergic rhinitis in Jordanian patients with chronic rhinosinusitis. Methods:- Our prospective study included 115 participants, of both sexes, aged 18-38 years and with clinical features of chronic rhinosinusitis diagnosed by endoscopic and radiologic criteria at King Hussein hospital, King Hussein medical center, Amman, Jordan, during the period Jan 2015-Feb 2016. Allergic rhinitis was diagnosed in terms of the patient’s history including frequent inhalant allergens. After finishing the physical examination and recording the endoscopic detections, the data was analyzed and P value was recorded significant if < 0.05. Results:- The mean age of participants was 32 years. Males were more affected than females, 57.4 %(66) and 42.6 %(49), respectively. The incidence of polypoid and none-polypoid rhinosinusitis was 54.8 % (63) and 45.2 % (52), respectively. The patient s’ most frequent clinical features were nasal discharge (93.04%) and blockage (90.4%).There were no significant discrepancies in allergic response between polypoid and non-polypoid chronic rhinosinusitis patients. Conclusion:- Allergic responses in Jordanian chronic rhinosinusitis patients are more than in Jordanian general population in Amman with allergic rhinitis only.
