Determination of Etiologic Factors in Chronic Rhinitis by Bacterial and Fungal Culture ofʹ Nasal Discharges

Chronic Rhinitis (CR) is a common disease of upper respiratory tract. The clinical signs are Rhinorrhea, nasal obstruction, sneezing and itching. Which may lead patient refer to ORL clinics. CR may be due to non-allergic infectious and non-infectious or allergic etiologic agents. In order to study the etiologic agents and the value of Lab. techniques in diagnosis of CR, a prospective study was undertaken over a 14-month period on 100 patients suffering from CR referring Emam Reza Hospital. Clinical examination and Laboratory tests including cytology smear. Bacterial and fungal culture of the nasal discharge were performed for each patient. 56% of the patients were female and 44% were male. CR was common among the age group 10-19 years old. Rhinorrhea (97%), nasal blockage (87%), sneezing and itching (66%) were the common clinical signs. Nonseasonal Permanent CR was observed in 54% of the patients and 46% had seasonal rhinitis. Personal and familial allergic history was specified in 42% and 24% of the patients respectively. Using cytologic smear of nasal discharges, neutrophilic inflamation in 43%, eosinophilic inflamation in 18% and combined inflamation in 18% of sample was diagnosed. Coagulase negative staphylococci (54%) and aspergillus SPP (18%) were the most common bacteria and fungi cultured respectively. The results confirmed that laboratory tests such as cytology smear and culture of nasal discharge are very helpful for precise diagnosis of chronic rhinitis and its related etiologic agents.
