Abstract

BACKGROUND: Grass pollen allergy is an important trigger for the development of respiratory disorders. Defining the grass pollen season onset is critical for correct allergy diagnosis and personalized therapy. The development of a pan-European sentinel network for allergic diseases has raised the problem of translating the Google search terms into different European languages as well as defining specific pollen season characteristics in different regions. Grass pollen allergy was investigated due to high allergenicity and wide expansion of grass pollen in Europe.

OBJECTIVES: The aim of this study was to examine which translations of "hay fever", "grass", and "rhinitis" could be used in the native Cyrillic languages, especially in Ukrainian and Russian, and to compare the seasonality of allergic respiratory queries in Ukraine with the grass pollen counts.

METHODS: Google Trends (GT) was used to search Google queries concerning grass pollen allergy: "allergy", "hay fever", "runny nose", "grass", "asthma", and "pollen". The Cyrillic terms in Ukrainian and Russian were used. The search was done for the period from 2013 to 2017. Pollen collection from 2013 to 2016 was conducted using volumetric methods. Average daily temperatures were obtained from http://gismeteo.ua. Correlations were assessed by Spearman (R) test.

RESULTS: The Ukrainian Google users searched the Cyrillic equivalents for "runny nose", "grass", and "asthma". Due to the GT queries profile, Ukraine had a "D" pattern according to the classification, developed by Bousquet J et al (2017). In Ukraine, the

CONCLUSIONS: The terms "grass", "allergy", "hay fever", and "asthma" (in their Cyrillic equivalents) are required in Ukraine to account for the grass pollen exposure by GT. The study of GT may be a useful tool to make an assessment of the grass pollen season for the prevention and minimization of exposure to significant grass pollen concentrations.
