When the numbers of SEB gene copies were compared between the groups, there were statistically significant differences between groups A and C (p<0.0001), and between groups B and C (p=0.002).Conclusion: Higher rates of SEB positivity in serum samples and higher numbers of SEB gene copies in concha samples indicate that Staphylococcal superantigens may be associated with CRS development.

Abstract

Objectives: This study aims to investigate the presence and levels of Staphylococcal enterotoxin B (SEB) in chronic rhinosinusitis (CRS) cases with or without nasal polyps.Patients and Methods: The study included 38 patients with CRS. Patients were divided into two groups as CRS group with nasal polyps (group A, n=18) and CRS group without nasal polyps (group B, n=20). The control group (group C) consisted of 15 patients. Staphylococcal enterotoxin B levels were measured in concha supernatants and serum samples in all three groups and in polyp tissues in group A by using enzyme-linked immunosorbent assay. Real-time polymerase chain reaction analysis was used to reveal enterotoxin B gene expression in polyp and concha tissue samples.Results: Staphylococcal enterotoxin B levels were positive in 11 (78.6%) and 11 (55.0%) patients, and in one (6.7%) patient in group A, B, and C, respectively. A statistically significant difference was detected between groups in terms of SEB positivity (p<0.0001). When the numbers of SEB gene copies were compared between the groups, there were statistically significant differences between groups A and C (p<0.0001), and between groups B and C (p=0.002).Conclusion: Higher rates of SEB positivity in serum samples and higher numbers of SEB gene copies in concha samples indicate that Staphylococcal superantigens may be associated with CRS development.

Özet

Amaç: Bu çalışmada nazal polipi olan veya olmayan kronik rinosinüzit (KRS) olgularında Stafilokokal enterotoksin B (SEB) varlığı ve seviyesi araştırıldı.Hastalar ve Yöntemler: Çalışmaya KRS'li 38 hasta dahil edildi. Hastalar nazal polipli KRS grubu (grup A, n=18) ve nazal polipsiz KRS grubu (grup B, n=20) olmak üzere iki gruba ayrıldı. Kontrol grubunu (grup C) 15 hasta oluşturdu. Stafilokokkal enterotoksin B seviyeleri enzim-bağımlı immünosorbent analiz kullanılarak her üç grupta konka süpernatantlarında ve serum örneklerinde ve grup A'da polip dokularında ölçüldü. Polip ve konka doku örneklerinde enterotoksin B gen ekspresyonunu ortaya koymak için gerçek zamanlı polimeraz zincir reaksiyon analizi kullanıldı.Bulgular: Grup A, B ve C'de SEB seviyeleri sırasıyla 11 (%78.6) ve 11 (%55) hastada ve bir (%6.7) hastada pozitif idi. Gruplar arasında SEB pozitifliği açısından istatistiksel olarak anlamlı derecede farklılık saptandı (p<0.0001). Gruplar arasında SEB gen kopyası sayıları karşılaştırıldığında, grup A ile C arasında (p<0.0001) ve grup B ile C arasında (p=0.002) istatistiksel olarak anlamlı derecede farklılıklar vardı.Sonuç: Serum örneklerinde daha yüksek oranlarda SEB pozitifliği ve konka örneklerinde daha yüksek sayılarda SEB gen kopyası olması, Stafilokokal süperantijenlerin KRS gelişimi ile ilişkili olabileceğini gösterir.
