Evaluation of the IgE reactivity of common pandora parvalbumin in a Moroccan population and action of heating and enzymatic treatments

The aim of this study was to evaluate the immunoglobulin E (IgE) sensitivity to common pandora (Pagellus erythrinus) parvalbumin (CPP) in a Moroccan population from the Fez region, and then to study the effect of temperature and enzymatic digestion on the allergenicity of CPP. This work was conducte...

Evaluation of specific IgE showed that 11.8% of patients present higher values (>150 IU/ml).
