Determination of the
cytokine (IL-10, IFN-γ, IL-5) response to BLG
revealed significantly higher IL-10 levels during
the tolerance phase (212.93 vs 142.46 pg/ml, P =
.011). There was a significant increase in BLGIgG4
and the BLG-IgG4/IgE ratio in the tolerance
phase when compared to the symptomatic phase.
