MOLINA-SAENZ, Mónica María; VILLA-ARANGO, Ana María e CARDONA-VILLA, Ricardo. Safety of subcutaneous immunotherapy with tyrosine-adsorbed house dust mite extracts in patients with allergic disease. Rev. alerg. Méx. [online]. 2017, vol.64, n.1, pp.52-65. ISSN 2448-9190. https://doi.org/10.29262/ram.v64i1.233.
Background:
In spite of allergen-specific immunotherapy (SIT) multiple benefits, its use is restricted in some countries owing to concerns about severe adverse reactions.
To evaluate systemic adverse reactions in patients with atopic dermatitis, allergic asthma, allergic rhinitis and allergic conjunctivitis who received subcutaneous immunotherapy with tyrosine-adsorbed Dermatophagoides and Glycyphagoides dust mites extracts.
Methods:
Retrospective study of the 2010-2015-period that included 773 patients diagnosed with IgE-mediated diseases, where the safety of allergen-specific immunotherapy was described according to the World Organization of Allergy subcutaneous immunotherapy-induced systemic reactions classification system.
Results:
79.7 % of patients had rhinitis, 54.9 % asthma, 34.5 % conjunctivitis and 16.4 % atopic dermatitis. Out of 12,546 tyrosine-adsorbed extract doses, 45 systemic reactions were recorded: 12 were grade 1 (30 %), 27 grade 2 (67.5 %) and 1 was grade 3 (2.5 %); the reaction rate was 0.35 per 100 administered injections, for an incidence rate of 5.8 %. No fatal reactions occurred.
Conclusion:
The frequency of systemic reactions with subcutaneous immunotherapy with Dermatophagoides farinae, Dermatophagoides pteronyssinus and Blomia tropicalis tyrosineadsorbed extracts was similar to that reported with other extracts.
