Abstract
Aim: To observe the association of peripheral blood eosinophil percentage in patients with allergic nasal polyps.
Design: Descriptive cross-sectional study
Place and duration: Pathology Department of Bakhtawar Amin Medical & Dental Hospital, Multan from September 2020 to August 2021.
Methodology: Blood samples of all the cases operated for nasal polyps in Bakhtawar Amin Trust Institute are drawn before surgery to look for eosinophils. Family and past history of allergy is recorded. Histopathology of all the operated specimen of nasal polyps is done and sample for eosinophil count is collected again in cases that proved to be allergic nasal polyps on microscopic examination to look for any alteration in eosinophil percentage in blood on excision of polyps.
Results: Twenty nine out of forty (72.5) percent of patients with allergic nasal polyps reveal increase in peripheral blood eosinophil percentage that returned to normal in 26(65%) patient on excision of nasal polyps.
Conclusion: The study disclosed a notable link between allergic nasal polyps and peripheral blood eosinophil percentage and this association is further enhanced by the fact that the blood eosinophil count returned to normal on removal of nasal polyps.
