Immunotherapy
SLIT was performed using a preparation of carbamylated allergoid (LaisĀ®,
Lofarma SpA, Milan, Italy), biologically standardised in allergenic
units (AU, 1:1000 AU), prepared as orosoluble tablets (allergoid SLIT),
and administered according to the recommendations by the manufacturer.
The patients started with the maintenance 1000 AU dose, taken regularly
twice a week for house-dust mites and 5 times a week for pollens.
