[Drug allergy among patients suffering from nasal polyps].
The study was performed in order to evaluate quantity and morphology of nasal polyps in patients with diagnosed drug allergy to aspirin, antibiotics, polocain, procain and other drugs. The study included 60 patients (27 females, 33 males aged between 18-69 years). Nasal polyp morphology was examined under electron microscope and light microscope. Morphological evaluation of epithelial and subepithelial structures was done under light microscope, taking not of inflammatory infiltration type, basal membrane, as well as degree of intestinal edema. Evaluation of epithelial cell type, their relative proportion, as well as area percentage covered by cilium, microvilli and squamous epithelium was done under electron microscope. Polyps in patients with idiosyncrasy to polish aspirin and sodium metamizole (12 patients) featured increased eosinophilic infiltration, thickened basal membrane, with elevated eosinophil percentage differential count. The epithelial percentage area was covered by squamous cells without villi. Polyps associated with idiosyncrasy to polish aspirin differed morphology compared to polyps originality from patients allergic to other medications. On the other hand polyps from patients allergic to other drugs, such as: penicillin, procainamide were morphologically (electron light microscope, light microscope) similar to those polyps caused by inflammatory factors.
