Sensitization to new pollen allergens in the Republic of Belarus
Belarusian State Medical University, Minsk, Republic of Belarus
Vestnik VGMU. 2026;25(2):87-92.
Abstract.
Objectives. To assess the prevalence of sensitization to pollen from invasive plant species in residents of the Republic of Belarus and conduct comparative evaluation of immunoblotting method using self-made pollen allergen extracts with ELISA using commercial allergen solutions.
Material and Methods. The study was conducted on 106 sera from patients with pollinosis (56 men, 52.8%; 50 women, 47.2%), an average age was 31.66 ± 10.25 years). The study included the determination of specific immunoglobulin E by immunoblotting using in-house allergen extracts and ELISA.
Results. Specific IgE antibodies to the commercial goldenrod allergen were detected in 20 patients using the ELISA method and in 16 patients using the immunoblotting method using our own goldenrod pollen extract, in 5 patients to parietalis using the ELISA method, in 2 patients to Scots pine and box elder using the immunoblotting method.
Conclusions. The spectrum of sensitization expands to include invasive species (goldenrod, box elder, pellitory), as well as some species rare in their ability to cause hay fever (Scots pine).
Keywords: pollinosis, goldenrod, pellitory, specific immunoglobulins E, pollen extract, allergen.
Sources of funding. The study was carried out within the framework of the research work «Clinical features and characteristics of sensitization in patients with hay fever» within the framework of the task «Study allelic polymorphisms of genes associated with the development of hay fever» of the state scientific research program 3 «Biotechnology-2», subprogram 3.2 «Genomics, epigenomics, bioinformatics» for 2023–2025.
