| description | Сurrent allergen-specific immunotherapy (AIT) is the most pathogenetically justified method of the IgE-dependent treatment of allergic diseases. Subcutaneous (SCIT) and sublingual (SLIT) AIT are currently used in wide clinical practice. Sublingual immunotherapy is characterized by the convenience of use, decreased incidence of systemic and local side effects, and proven clinical efficacy. However, sublingual form of home dust mite allergen for AIT is not yet produced in Russia. Previously, the technology for sublingual form of D. farinae (Der f) mites allergen was developed in our laboratory, and this extract was shown to be non-toxic and free of any significant side effects. We obtained a sublingual form of mixed D. pteronyssinus (Der р)/D. farina mites allergen for sublingually allergen-specific immunotherapy. We studied physico-chemical and immunobiological properties of the Der р and Der f mites phenol-free water-salt mixed extract (WWSME). WWSME was studied after sterilizing filtration. WWSME was analyzed by electrophoresis in polyacrylamide gel in the presence of dodecyl-sodium sulfate and reverse-phase high-performance liquid chromatography. ELISA was performed with polyclonal rabbit serum, obtained by sensitization of animals with recombinant Der f1 and Der f2 allergens. ELISA shows positive reaction of WWSME with IgG-antibodies of rabbits. We studied acute and chronic toxicity of received mixed allergen in laboratory animals. Pathomorphological studies have shown that WWSME has no detectable toxicity and does not cause local irritation in the animals. The WWSME product contains native proteins, retains immunogenic properties, is non-toxic and does not cause significant side effects. This extract can be used as the basis for designing a sublingual form of dust mite mixed allergen, which is especially promising for pediatric applications. |
