Nasal polyps Treatment

Staphylococcus aureus is a frequent colonizer of the upper airways in chronic rhinosinusitis with nasal polyps, but also resides intramucosally; it has been shown that secreted staphylococcal proteins such as enterotoxins and serine proteases induce the release of cytokines such as IL-5.  Recent study have analyzed nasal polyp tissue freshly obtained during routine surgery, which did or did not contain cultivatable S. aureus, to study spontaneous IL-5 production by nasal polyp tissue over 24 and 72 h in tissue culture. In S. aureus-positive samples was interfered by killing the bacteria using antibiotics or S. aureus specific intravenous staphylococcal phages (ISP), active or heat-inactivated This study also demonstrate that cultivatable S. aureus may be found in type-2 inflamed nasal polyps; the pathogen is replicating within 24 h and secretes proteins, including enterotoxins and serine proteases. The presence of S. aureus was associated with a significantly higher release of IL-5...
