Clinical Trial Summary

Metalloproteinases (MMPs) constitute a family of endopeptidases that cleaves the extracellular matrix as collagen included in the eardrum. Activity of MMP has been shown in some otitis media with effusion (OME) fluids. These enzymes could be directly linked to the prosnostic of OME as it may damage the eardrum and leads to tympanic atrophy.

The main goal of the study is to find out the correlation between activity of MMPs and tympanic atrophy. The investigator will also study if there is any clinical predictive factors in relation to the level of MMPs.


Clinical Trial Description

The investigator will include 35 children under 12 years old with OME and who need tympanostomy or tube placement under general anesthesia. Middle ear effusion will be collected, divided in two and frozen.

The investigator will perform ELISA tests to measure the level of MMP2 MMP9 MMP7 et TIMP2 (inhibitor of MMPs). The investigator want to compare the level of MMPs between healthy eardrum and atrophic membrane.

Clinical data will be collected such as age, gender, chronicity of the OME, quality of the eardrum and middle ear effusion type to see if there is any difference when MMPs level is higher. ;
