Abstract
OBJECTIVE
The aim of this study was to clarify the site of primary pathology in otitis media with effusion.
STUDY DESIGN AND SETTING
The levels of the inflammatory mediators TNF-alpha, TNF-beta, IL-1beta, IL-8, IL-6, IL-4, IL-2, IL-5, IL-10, and IFN-gamma were measured in 54 pairs (108 samples) using specific enzyme-linked immunosorbent assays (ELISAs).
RESULTS
The levels of pro-inflammatory cytokines TNF-alpha, TNF-beta, IL-1beta, IL-8, anti-inflammatory cytokines IL-5, IL-4, IL-10, IL-6, and cytokines with immunoregulatory potential IFN-gamma, IL-2 were different between both ears of the same patient.
CONCLUSION
The results suggest that in one individual both ears have different immunological processes or rates and this has implications on using the opposite ear as a control in clinical trials.
SIGNIFICANCE
Profiles of interlink of examined cytokines within the samples of both ear effusions were significantly different. A significant bilateral difference was found in the levels of IFN-gamma.
