ABSTRACT
Staphylococcus aureus secretes numerous superantigenes which trigger the inflammatory mechanisms of sinus mucosa and cause chronic rhino-sinusitis. This study was designed to evaluate the role of staphylococcus aureus superantigens in polyp tissues of patients with chronic rhino-sinusitis in comparison with a control group. Polyp tissue samples of 28 patients and mucosal specimens of 19 healthy individuals were evaluated for staphylococcus aureus bacterium superantigens, exotoxins A, B, C and D and TSST-1 with RT-PCR and ELISA methods Rasoul Akram Hospital during 2 years. Polymerase chain reaction [PCR] results revealed that 88.2% of the patients and 45.5% of the controls had at least one type of superantigen [P=0.03]. Evaluation of superantigens using ELISA method showed presence of at least one type of superantigen in the nasal samples of all patients and in 35.3% of the controls [P < 0.001]. A relationship between staphylococcal superantigens and nasal polyps is concluded from this study which indicates the probable role of these superantigens in the pathogenesis of nasal polyposis
