RELATIONSHIP OF ALLERGIC DISEASES, POLLEN EXPOSURE AND COVID-19 IN GEORGIA.

Allergic diseases have been recognized as one of the global health issues and affect about a third of the worldwide population. COVID-19 pandemic has raised concerns about the risk of infection and the severity of COVID-19 infection in patients with asthma and allergic rhinitis. The aim of our study was to define the relationships between pollen exposures and SARS-CoV-2 infection rates in Georgia, as well as to characterize the Covid-19 autoimmune and antiviral responses in Georgian allergic patients with different sensitization patterns. Data on daily COVID-19 positivity rates, case fatality rates, and pollen concentrations from February 2020 to November 2022 were collected in Tbilisi, Kutaisi, and Batumi. Diagnostic parameters, including total IgE, specific IgE, eosinophil counts, anti-nuclear antibodies, and Covid-19 antibodies, were assessed in 181 atopic patients and 24 healthy controls with confirmed SARS-CoV-2 infection. Laboratory findings revealed significant variations in eosinophil counts and total IgE levels among the groups. ANA positivity did not exhibit substantial differences between atopic patients and healthy controls. Individuals with indoor allergies displayed lower SARS-CoV-2-specific antibody levels, potentially explained by variations in adaptive immune responses. There was no correlation between pollen concentration and COVID-19 epidemiological characteristics, indicating that pollen had no effect on virus epidemiology.
