Results from this study3

No result from this study comes from a test of the peptide.

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In children with otitis media with effusion, mean VIP levels were 50.91 pg/ml in serous and 54.86 pg/ml in mucoid middle ear effusions.

  3. 03HumanEndogenous levelObservational studyOther

    In children with otitis media with effusion, VIP levels correlated inversely with substance P levels in middle ear effusions.

    In plain wordsIn children with middle ear fluid, higher substance P was linked to lower levels of the body's own VIP.

    Summary
    This is the first report demonstrating high levels of substance P (SP) that inversely correlate with vasoactive intestinal peptide (VIP) levels in middle ear effusions (MEEs) of patients with otitis media with effusion (OME).
